Maybe my friends are interested in Punching machine The knowledge of is not particularly clear. Most of the materials of dies and tools used for punching machine pressure processing are alloy steel, carbon tool steel and hard alloy. They all have a common feature: high strength and hardness, relatively low plastic toughness, which is quite beneficial to metal deformation. But it is not good for the safety of operators. How can we give consideration to both? according to Rack punching machine manufacturer Through years of experience, starting with the improvement of the punching machine's process method, the preventive measures have been found, with good results, simple methods and cost saving.

The main consideration of punching machine process improvement is to reduce stress concentration and improve the plasticity of dies and tools.

In general, the more serious the stress concentration is, the easier it is to cause local damage of the mold; The worse the plasticity of the module, the easier it is to cause mold cracks. Reduce stress concentration and improve plasticity Reduce stress concentration by optimizing the geometric structure of the tool. In addition to avoiding sharp corners and sharp corners on the appearance and edges of the mold and tool, the punching machine should also pay attention to:

How to ensure the safety of operators when operating the punching machine?

1. Pay attention to "three minds and one mind". The stress center of the workpiece, the geometric center of the mold and the pressure center of the press are "three in one", which can avoid the damage of the mold due to the stress concentration caused by eccentricity.

2. The side of the upper mold facing the operator should be made into a bevel as far as possible, which can not only increase the operating space, but also reduce the probability of the mold edges and corners being deformed and damaged under the effect of stress due to frequent use, thus popping out.

3. During the blanking process, ensure that the hardness of the male die is slightly less than that of the female die HRC5 (hardness value); When punching small holes with diameter less than 2mm, the guide sleeve of the punch should be as long as possible; During continuous blanking, the first hole should avoid unilateral or asymmetric, in order to reduce the risk of punch damage and ejection.

4. The discharge plate of the mold and the upper and lower molds should be closed as far as possible, especially the side close to the operator.

5. The extrusion processing energy is very large, and the entrance angle a of the extrusion die has a great influence on the unit extrusion force. When α= The deformation resistance is small when the angle is 40 °~60 °, which is very helpful to improve the safety performance.

How to make Hydraulic punching machine Stay better?

In the advanced industrial processing industry, punching has always been an indispensable skill process, and high-speed and high-quality punching is crucial to the processing quality and effect. Therefore, the high-quality and diversified hydraulic punching machine has become the new favorite in the market, especially the hydraulic punching machine with rich functions, heat resistance and wear resistance, which is widely used in many professional fields, We also find that many manufacturers have begun to introduce such reliable equipment with very good results. So what can we do to keep the hydraulic punching machine in a better state?

First, ensure the fit of the application field

The hydraulic punching machines with multiple functions are suitable for different process requirements in actual application, so it is important to find the appropriate product models under the guidance of official experts' suggestions and ensure that the purchased hydraulic punching machines have a good fit with our processing field.

Secondly, ensure the normative management of operations

Of course, no matter in large processing sites or small engineering fields, strict equipment management standards need to be formulated, that is, the operation authority and mode management of hydraulic punching machines need to be done well, especially the management of equipment safety and personnel safety.

Once again, monitor and maintain the equipment status

Of course, under the guidance of experts, we should also do a good job in monitoring the relevant parts of the hydraulic punching machine, including the monitoring of the operating effect and state stability of the equipment and problem solving. In addition, the careful maintenance with professional technical support can keep all parts of the hydraulic punching machine in good condition for a long time.

In a word, in order to keep good production effect and equipment status of hydraulic punching machine for a long time, on the one hand, we need to ensure that the selected equipment type has a good fit with the specific processing requirements of the industry; on the other hand, we need to ensure that the equipment authority management and standardized operation management maintain a sufficient scientific and reasonable standard, and we need to emphasize the hydraulic Punching machine equipment It is also crucial to do a good job of condition monitoring and maintenance in all aspects.
