Discussion on CNC System of Medium and High Grade Punch in China

Dec 26

Discussion on CNC System of Medium and High Grade Punch in China High-performance CNC system, spindle, nano-precision grating and other functional components and machine design and manufacture of the core technology, the development of high-end CNC punch the most critical factor. CNC system is equivalent to the brain of CNC machine tools, the value of the machine accounted for one-fifth. Its role is to set the user’s processing goals, converted into specific processing steps, the command machine. At present punching process, manufacturers of CNC machine tools in China, many are buying foreign CNC system, integrated with their own machine tools. In recent years, the domestic low-end CNC system to the basic foreign competitors out of the Chinese market; the high-end market is just the opposite bus bar bending machines, only accounted for less than one-tenth of domestic.

High-end CNC system is basically in the market, such as Farnaco and Siemens in the hands of manufacturers. Foreign high-end CNC system, high-speed and high-precision performance, as well as in the five-axis processing and intelligent than the performance of domestic products are good, and the average time to failure is four times the domestic product. CNC system architecture, hardware and software accessories, high-speed high-precision algorithm requires a long time to study and improve tube drilling machine. The backwardness of domestic electronic basic industry determines the weak performance of China’s high-end CNC system. In addition to the level of the gap between the CNC system, the key components of the weak field also limits the height of domestic machine tools. In some machine tool exhibition, can also see the application of domestic or high-end CNC system Siemens CNC machine tools, and foreign assembly of the same ‘brain’ compared to the machine, the speed is only one-third of foreign, error range is someone else .

What are the decisive factors in punch machine life?

Nov 14

Punch machine manufacturers feel that the life of the punch press die depends on the closed mold of the high precision of the body of the fine thermal penalties to create exactly the punch press placement mold, close mold accessories and chisel monopoly, health and respect for the joints is not to be cautious following:

1, before the operation: through the pure mold sets of adjustment, all have chastity all components before the equipment, punch marks around the guide sleeve and the demolition of the dirt inspection valve mold lubrication; check guide sleeve, stamping, mold sliding reference individual Bumps the omission of glitches, such as a certain stone to gently remove the fraud; large station to mobilize the tactical installation of the punch, slide in the guide sleeve, is the top of a number of locking screw lift must be safe with the disassembly tools to lock.

2, on the turntable and punch at the end of the mold laying anti-fresh German love coaxial precision turntable.

3, in accordance with the order of mold assembly mold and punch to install the insurance purpose of the turntable in order to avoid the abnormal request more hard to control the mold object loaded wrong, anti-installed.

4 installation fixation, punch mold should be mold-mounted seat of the lock and tighten the screws after the review.

5, the punch mold should be trapped in a timely manner, grinding or grinding the use of flexible frivolous mold edge wear, wear and tear sheet metal stamping die material and die life. The idea of ​​punching is to change the circular motion into straight line dredging by the main electric head, the flywheel, the clutch-inspired gear, the crankshaft (or the eccentric gear) and the running of the quail, to realize the linear motion of the slider , From the main motor to the link for the active circular motion.

The link between the link and the slider need circular motion and linear motion of the transfer point, the negotiation is still there are two kinds of institutions, one for the ball type, one for the pin type (cylindrical), through this mechanism will circle The motion turns into a linear motion of the slider. The punch presses the material and makes it plastic deformation, and obtain the appearance and accuracy of the request, so it is necessary to join the group mold (sub-mold and die), the data placed in the meantime, Deformation, processing exerted on the force of the material compiled by the anti-persuasion force, by the impulse of the clumsy nature of the received.

Influence of Die Material of Punch on Operation

Oct 20

In order to solve this problem, you need to troubleshoot the problem, so how to deal with grinding punch punch machine can not return to punch failure, by the slider tightly on the handle, press the connection, through the punching machine Of the table fixed with the guide pin of the template, the upper and lower die, guide sleeve.

Work, stripping stop pin, waterfall and slider mode, first press the location of the stripper plate material, and then press the punch mold material. In the die-cutting round billet positioning, downward movement, blank pressure, from the hole, and continue to fall into the cavity, resulting in permanent deformation stamping die material, after processing the workpiece required. When the workpiece between the punch and the top sheet is held, the waste is firmly fixed to the punch. In the camera mode, the punch presses the spring work piece by spring force from the die; wasting a spring through the discharge plate while passing through the discharge plate, so as to complete the whole process. The material is sent to the step, for the next process, and so on.

There are a number of reasons why punching molds are unloaded, the reason for the different treatments is different:

1, accurate positioning Inaccurate positioning or feed device can be adjusted or fed to the device.

2, guide pin, causing the movement is not in the solution smoothly, can replace the guide column.

3, puncture injury or appearance is not smooth, but also can form the punch mold emissions, can be solved, not stamping.

4, lifting equipment set unreasonable, reset.

5, the shortage of ejector or removal of material shortage, by changing the spring or spring processing separator.

In the punch press, the slide block is driven by the mold so that the action, the main and auxiliary stamping effects, the slider should follow certain principles to meet the processing requirements, then the design, the slider should follow the principle design.

1. Installed in the punch Press the slider of the body should be simple, compact structure, reasonable layout, easy installation, as far as possible by the sliding body of the geometric center of the sliding parts center.

2. To ensure the accuracy of the slider, it should have the appropriate accuracy requirements, guide length is sufficient.

3. Reasonable cross-sectional dimensions and strength of the plate position, under the premise of strength and stiffness, minimize the weight of the slider, travel.

Because the slider structure is relatively complex, in the design process to pay attention to it, more carefully considered.

In order to solve this problem, need to deal with failure, then how should deal with the failure of the punch punch punch can not be punched, the punch through the mold block stamping, punching machine connection, Stamping machine table used in the next fixed template, the upper and lower die with the guide column, guide sleeve guide.

When working, the steel strip to the position of the stop pin, when the mold with the slider on the waterfall, first press the material of the stripper plate, and then punch the stamping die material. The punch blank is positioned in the lower die, moving downward in blank pressure, from the hole, and continues to descend into the cavity, resulting in permanent deformation of the material in the stamping die after the desired workpiece is machined. When the workpiece is clamped between the punch and the top block, the waste is also firmly fixed to the press. Punch manufacturers in the camera mode, the top piece of the workpiece through the elastic spring force ejector from the mold; the same time to waste in the hoop, the discharge plate by the spring of elastic, thus completing the entire process. Material sent to a step, for the next step of the process, so back and forth.

There are many reasons for the press die unloading, the reasons for different treatment methods are not the same:

1, the precise positioning of feeding equipment is not accurate or feeding adjustable feeding or positioning device.

2, the internal guide column pull, resulting in uneven movement can be replaced within the column-oriented solutions.

3, perforation damage or appearance is not smooth, but also the formation of stamping die discharge, can replace the stamping solution.

4, the top material device set unreasonable, reset.

5, the inadequacy of the ejector or remove the lack of material, by replacing the spring or spring handle stripper.

Punch, the role of the slider is to drive the mold to complete the action, mainly to play a secondary hot stamping effect, slider design should follow certain principles to meet the processing needs then, the slider should follow the design principles.

1. Installed on the punch slider on the various institutions should be simple structure, compact, rational layout, easy installation and adjustment, as far as possible so that the center of sliding components through the geometric center of the slider body.

2. In order to ensure the accuracy of the punch on the slider, it should have the appropriate accuracy requirements, and guide the length of sufficient.

3. Under the premise of strength and rigidity, reasonably determine the cross-sectional size and the location of the reinforcement plate to minimize the weight of the slider, travel.

4. Because the slider structure is more complex, in the design should be more careful attention to it in the process of comprehensive consideration.

On the punch mold how to maintain

Oct 10

Daily production capacity is mainly used to speculate punch presses per minute stroke number and the number of presses required to meet the production needs of the group. In this way, it is necessary to select the short-stroke high-speed punching machine for the processing of embryo and perforation. For the process of molding and extension, it is necessary to select the process characteristics such as parts processing characteristics, quality characteristics and tool characteristics. Long stroke and slower speed punching presses are used in the process of stamping, embossing and embossing. When the machine is in the bottom dead center, it has high energy short stroke punch.

1, punch mold use, the guide column and guide sleeve to add regular oil.

2, the re-production time in the upper and lower punch mold response to sliding parts and should be repeated on the edge of oil or stamping oil, and punch to see each fastening components are loose, timely detection and timely management, prevention of loose displacement, the formation of mold destruction And so on.

3, is strictly prohibited double punching punch, in addition to stamping materials, lubricants, cleaning hooks outside the Henan punch should leave the homework area.

4, the edge of iron powder is not sluggish too much, should be promptly disposed of inundation and timely accounting for waste.

5, the production of the mold after the implementation of the overall inspection, a comprehensive clear Sassafras, clear Sassafras should be promptly applied after the anti-rust oil, and press closed to ensure clean mold in order to facilitate the normal use from this.
