A waste material pushing and turning mechanism and stamping die

Abstract

The invention discloses a waste push turnover mechanism and a stamping die. The waste push turnover mechanism comprises an air cylinder, a support, an electromagnet and an elastic top pin. The first end of the support is connected with an air cylinder rod on the air cylinder. A push plate is arranged at the second end of the support. The electromagnet is fixedly installed on the push plate. The elastic top pin is installed on the push plate and is located on the side, far away from the support, of the push plate. Through the waste push turnover mechanism and the stamping die, waste can fall with the preset posture, thereby sliding out smoothly.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a waste material pushing and turning mechanism and a stamping die. Background technique [0002] The design of the stamping process plan for automobile panels is to determine the sequence of drawing, trimming, punching, flanging, shaping and other processes and the specific content of each process according to the product structure shape and technical requirements. At the same time, the convenience of stamping operation, Safety, reasonable mold structure, smooth discharge of workpieces and waste, etc. Especially in the trimming process, it is generally required that the scraps slide off the mold smoothly after trimming, and it is not allowed to accumulate scraps on the mold, otherwise accidental production accidents will occur and production efficiency will be reduced. It is especially critical for stamping scraps to slip in automated production lines, and poor slips of sc...

Problems solved by technology

[0006] (1) The existing technical solution is a waste material hook installed on the upper die, and the upper die moves upward to lift the waste material to avoid being stuck between the waste material knives, but the movement of the waste material is unstable after being lifted up and cannot be controlled In the direction of movement, it may fall into the mold cavity, or fail to fall into the waste chute, resulting in failure to smoothly discharge out of the mold, requiring manual cleaning

[0007] (2), for the waste material that is relatively close to the inside of the mold or the waste material that is relatively vertical (with a large angle with the horizontal direction) after cutting, the device in the prior art solution cannot be used

[0008] (3) When the waste material in the inner area slides down vertically, the relative position of the waste material and the slideway is limited, and the posture is uncontrolled, making it more difficult to slide out, and the size of the mold needs to be increased, which will increase the cost of the mold
