In many of our country's machinery manufacturing industries, presses are essential mold processing machines and equipment. Precision punch presses are also many types and specifications models, so what do you need to know about high speed punch presses? What are the differences between high-speed punching machines and general punching machines? Is it just the difference in speed? Is a high-speed press better than a normal press? What do you need to pay attention to when buying a high-speed press? The following is a step-by-step analysis of the following.

High-speed press is the largest productivity in the stamping and punching process. There are many manufacturers of high-speed presses, each of which may have different technical characteristics, but they are all automatic presses designed for continuous high-speed stamping.
High-speed presses and high-speed punches are used for a large number of products that must be produced using sheet metal processing. Stator plates for electric motors and generators are classic products for high-speed stamping. Even small deviations in tolerances can lead to eddy currents, which can cause electromechanical components to overheat.
Each motor or generator requires hundreds of sheets of exactly the same shape. This requires a production process with consistent quality that is designed for mass production. This is where high-speed punches and stamping machines from JDM come in. They enable particularly high stroke frequencies and correspondingly fast cycle times.
High speed presses are the same as traditional mechanical presses and pneumatic precision presses, they all belong to the crankshaft type of presses and their principles are basically the same, but high speed presses are also a unique type of crankshaft presses.
The high-speed punching machine uses two slide balancing devices to ensure that the machine keeps balanced operation. Stable high precision, high speed punching machine crankshaft, transmission gears, bushings and other friction positions are hardened by heat treatment and then grinding processing, with extremely high wear resistance and stability, stable characteristics. Processing automation, labor saving, can be equipped with all the automatic loading mechanism to carry out automated production, reduce costs and improve productivity.
High-speed press series tiltable presses are widely used for stamping and processing of small precision parts such as precision electronics, communication equipment, automotive parts, computers, electrical products, and motor rotors. High-speed presses are suitable for many production of precision electronics, hardware parts processing, integrated unique alloy, high rigidity and shock resistance. The slider is designed with a long guide path and equipped with a slider balancer to ensure precise and stable operation. It can be matched with automated production requirements, high-speed punching machine to enhance productivity and reduce costs.
High speed punching machine with high number of slider strokes. The number of strokes of the slide, that is, the number of strokes per minute, the specific application of high-speed punching machine, the number of strokes of the slide is also used with the height of the loading die, the specific feeding distance.
High-speed punching machines are equipped with slider equalization equipment and foot shock absorbing equipment. The number of reciprocating movements of high-speed punching machines far exceeds that of other types of punching machines, resulting in the inevitable onset of very large stamping inertia, which is not always harmful to the stamping accuracy if not removed immediately, and will reduce the service life of the punching machine and the die.
High-speed punching machines are equipped with emergency braking equipment as standard.
It has high stamping accuracy and feeding accuracy.
High-speed punching machine has high rigidity and slider guiding accuracy.
The auxiliary equipment of high-speed punching machine is complete. High-speed punching machine has a complete set of auxiliary supporting equipment, such as common high-precision gap feeding equipment, equalization equipment, vibration and noise reduction equipment, which can ensure that it can give full play to the very high efficiency of the stamping role.
High-speed punching machine is better in terms of precision, tensile strength, speed, system software stability and actual operation of the structure, but it does not mean that Kor speed is better than the general one. However, it does not mean that the high speed press is better than the general one. The specific purchase decision should be made according to the actual necessity.
The market demand is becoming more and more fierce, and in order for a company to continue its development trend and enhance its competitiveness, it is necessary not only to save costs but also to improve the quality of products.
The key to punching machine accuracy are: one, parallelism, two, perpendicularity, and three, total clearance. Only then can we ensure that the dynamic lower dead point is within the difference, which will prompt the production of each commodity to meet the standard and the spare parts in the mold will not be destroyed. High precision punching machine can not only produce good goods, and the damage to the mold is smaller, not only saves the mold maintenance time but also saves the maintenance cost.
If your commodity mold requires a speed of 300 times/minute or higher, you should choose a punching machine with 1000 times/minute. Because the equipment can not be applied to the limit, and within 400 times / minute punch generally does not have a forced lubrication system, in the bone part of only using grease wetting. And the structure of punching pin adopts slider type, the accuracy can't be guaranteed, in the long-term work damage quickly, the accuracy is reduced, the mold is easy to destroy, the equipment and mold overhaul rate is high, and the delay, endanger the delivery time. And the use of three round positioning pin type punching system, precision and heat resistance is very good, forced grease under basically no wear.
Quality structure can guarantee the accuracy of the equipment. Punching machine foot base is the basic of the machine, and some brands of punching machine in the same tonnage foot base in the same tonnage is not great. Punching machine adopts variable frequency speed motor, low functional loss, high speed punching machine in the same tonnage to save power 30% up and down.
Ordinary type is generally below 110~200 times, while the high speed is above 200~1100 times.
The raw material of the shell of high-speed punching machine has high rigidity and performance, and the accuracy is more stable, while the common type is otherwise.
The general ones are manual type, foot pedal and CNC punching machine, etc., while the high ones are all CNC machine tools and fully automatic.
General have general and high precision, and high speed are high precision, even to 0.01mm.
General punching machine is important for electronic components and other manufacturing industry parts of the molding, drop and other cold punching die processing process; high-speed punching machine is commonly used in the production of high-precision parts manufacturing.
The grinding tool of general punching machine is a single stamping die, which increases the overhaul cost; the grinding tool of high-speed punching machine can be both a single stamping die and a continuous die.
As a matter of course, the price of high speed presses is higher than that of general presses.
The design of eccentric shaft of high speed punching machine is much stronger than normal, which can bear a lot and not easily deformed.
The important system software of high-speed punching machine adopts pressure display, which is a little more stable.
