automatic Hydraulic punching machine The equipment often used in stainless steel or display stand and angle iron industries has more advantages in speed and high quality due to its automatic control Full automatic punching machine It can be designed through an automated program, and then processing operations can be carried out directly, so it can reduce the production of defective products, and it can also complete mass processing operations, which can also benefit users in the use process.

Automatic hydraulics Punching machine Can it replace manual work? The answer is yes. The following explains the possibility of machine replacement from various perspectives, including actual case analysis and industrial development. To sum up, there are the following points:

1、 Machine replacement has become a trend. In recent years, it has been difficult for enterprises to employ workers, and the rise of workers' wages has become a common phenomenon. However, the product structure and profit margin of domestic manufacturing have not increased significantly. This makes enterprises either move their factories to underdeveloped areas with lower wages or find ways to reduce the use of workers. With the progress of robot technology, machine replacement has become a trend.

2、 The local government is carrying out the work of machine replacement in an organized way. The main measures are to make plans, support special funds, support financial services, and develop the robot industry nearby.

3、 Enterprises have encountered many problems in the process of machine replacement. For example, the early investment is large, the flexibility of the robot is not good enough, it cannot adapt to the replacement of the product line, and there is a lack of technicians who understand the robot.

whole Auto punching machine It can save a lot of manpower and material resources and greatly reduce the human cost. How to ensure the safety of operators when operating the punching machine

The die and tool materials used for punching machine pressure processing are mostly alloy steel, carbon tool steel and hard alloy. They all have a common feature: high strength and hardness, relatively low plasticity and 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? Based on years of experience, Sanuo Intelligent Environmental Protection Technology believes that starting from improving the process method of punching machine, it is better to find preventive measures, the method is simple and easy, and cost saving.

Square and round pipe punching machine The main consideration of process improvement is to reduce stress concentration and improve the plasticity of molds 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 tool geometry. In addition to avoiding sharp corners and sharp corners on the appearance and edges of molds and tools, pay attention to:

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, avoid unilateral or asymmetric holes at the beginning 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.
