Problems solved by technology

However, since the feeding of each station is automatically completed by the equipment, it is difficult to observe and judge manually, so it is often discovered after an abnormal situation occurs, and at this time the loss has already occurred

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] see figure 1 and figure 2 , as can be seen from the figure, the present invention’s method for preventing misalignment of continuous die feeding, pre-installs the upward detection pin 2 on the lower die 1, and sets the pin hole 4 at the corresponding position of the upper die 3, and the detection pin 2 is facing the pin hole 4. During normal feeding, the pin hole 4 is facing the hollow position of the workpiece 5, that is, the hole between the detection pin and the pin hole is the opening part of the workpiece. During each processing, since there is no obstruction, the detection pin can enter the pin hole. See figure 1 , since the pin hole is larger than the diameter of the detection pin, and the detection pin cannot reach the bottom of the pin hole, so the detection pin has no force. When the feed is not in place, such as too much or too little feed, when the s...

Abstract

The invention discloses a progressive die material conveying dislocation preventing method. the method comprises the steps that a detecting pin is pre-arranged on a lower die, a pin hole is formed in the corresponding position of an upper die, and in the normal feeding process, the pin hole is aligned to the hollowed position of a workpiece; when feeding is not carried out in place, the pin hole is aligned to the solid position of the workpiece, in the die assembling process, the upper die generates downward pressure on the detecting pin through the solid position of the workpiece, the detecting pin is made to move downwards, when the detecting pin moves by the set distance, the detecting pin triggers an induction switch, the induction switch is connected with a control system, and a progressive die is controlled by the control system to stop working immediately. According to the method, normal use of equipment can be effectively guaranteed, the situation that the workpiece and the equipment are bashed due to the fact that feeding is not carried out in place is avoided, and work is reliable.

Description

technical field [0001] The invention relates to the improvement of the structure of the continuous die, and specifically refers to a method for preventing dislocation of the continuous die. The invention can stop the continuous die when the continuous die is working and the material is too much or too little, so as to avoid crushing Workpieces and equipment belong to the technical field of continuous dies. Background technique [0002] The continuous mold refers to a mold that is composed of multiple stations, each station completes different processing, and the sequence of each station is related, and a series of different stamping processes are completed in one stroke of the punching machine. The continuous mold has the following advantages: 1) Stamping production efficiency is high. The continuous die can complete the blanking, flanging, bending, deep drawing, three-dimensional forming and assembly of complex parts, reducing the work of intermediate transfer and repeat...
