A rotary stamping die

Abstract

The invention discloses a rotary stamping die which comprises an upper die plate (1), a lower die plate (2), an upper die block (3), a lower die block (4) and a rotary shaft (5). The upper die block (3) and the lower die block (4) which are used for stamping a product (8) are arranged between the upper die plate (1) and the lower die plate (2), and the rotary shaft (5) which is used for driving the lower die block (4) to rotate is arranged on the lower die plate (2), is rotationally matched with the lower die plate (2) and is connected with an output shaft of an external motor (6) by a belt (7). The rotary stamping die is characterized in that an anti-collision mechanism which is used for preventing the upper die block (3) and the lower die block (4) from being collided with each other is arranged between the upper die plate (1) and the lower die plate (2). The rotary stamping die has the advantages that tool collision of the die can be prevented under emergency conditions, and accordingly operators do not need to frequently stop machines to maintain the rotary stamping die.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a rotary stamping die. Background technique [0002] Among the existing stamping dies, there is a rotary stamping die. Its working principle is to rotate the fixed die according to the beat, so that the movable die can continuously stamp out the required models at different positions of the fixed die to meet the requirements of multiple positions on the product. stamping needs. Especially for products that are evenly distributed in the circumferential direction, the same model can be punched out in the circumferential direction of the product only by rotating around the axis of the fixed die, which not only reduces the number of die punches and simplifies the die structure, but also relies on the same punch Complete the entire stamping process, so the consistency of each part of the stamped product is high. [0003] However, since the rotary stamping die needs to be conti...

Problems solved by technology

[0003] However, since the rotary stamping die needs to be continuously rotated at a certain angle to complete the stamping, the error in the rotation angle will directly lead to the coordination error between the fixed die and the movable die, and in severe cases, it will cause knife collision, which will damage the die

For stamping dies, the punch part is the most important part in the die, and its precision requirements and manufacturing costs are relatively high.

In the existing technology, the rotation angle error of the mold is often controlled through regular debugging, thereby reducing the situation of knife collision, but this not only greatly increases the labor intensity of the operator and reduces the processing efficiency, but also causes errors in the control program and slippage of the transmission parts. In the event of various emergencies such as dislocation, it is still impossible to avoid the situation that the tool will be damaged and the mold will be damaged.
