Abstract

The invention discloses a self-adaption material width determination device for a progressive die. The device comprises material guide plates which are arranged on a female die plate to form a material guide channel and a side blade stop block arranged on one side of the material guide channel, the material inlet end of the material guide channel is provided with a horn mouth, and the side blade stop block is connected with the female die plate through elastic parts; the two sides of the material guide channel are provided with side blades, the side blades on one side of the material guide channel are fixed on the material guide plates, and the side blades on the other side of the material guide channel are arranged on the side blade stop block in a front-back moving mode and connected with the side blade stop block through elastic parts. According to the device, it can be guaranteed that a die stably and continuously works and is evenly stressed; when a material belt enters the material guide plates, coarse positioning can be firstly performed on the material belt through the horn mouth material inlet end of the material guide channel, and then the side blade stop block on one side of the material guide channel and the side blades on the side blade stop block can make close contact with the material belt, so that the material belt is quickly and accurately positioned and the material belt width is determined.

Description

technical field [0001] The invention belongs to molds, in particular to an adaptive material width determining device for progressive dies. Background technique [0002] my country is still facing many thorny problems in the manufacture of nuclear power strip molds, which restrict the development of my country's nuclear power industry. One of them is how to accurately and quickly determine the width of strip blanks. If the material width cannot be determined accurately and quickly, various unfavorable phenomena will occur during strip punching, such as unsatisfactory forming, loud mold noise, skipping waste, etc., which will shorten the life of the mold and greatly increase the cost. The existing strip width limiting device is inconvenient to operate, and the precision is very low. For the material width when the existing material guide plate has no side pressure device, because there is a gap between the strip material belt and the material guide plate, the strip material b...
