Description

Technical Field

[0001] The utility model relates to the technical field of metal stamping, in particular to an automatic feeding detection mechanism. Background Art

[0002] In continuous automatic stamping production, the continuous stamping die can continuously stamp and form the product with the assistance of the continuous feeding mechanism. Because the continuous stamping die needs to stamp the product strip to be processed at a fixed processing point, it is necessary to accurately control the feeding step length of the feeding mechanism. The feeding detection mechanism is a structure that detects whether the product strip to be processed is fed into place. The feeding detection mechanism used in existing continuous stamping dies mostly has a relatively complex sensing structure or sensing method, which is not convenient for disassembly and maintenance, and the cost is high. For example, some spring return feeding detection mechanisms, after the product strip is fed into place, hits the spring and returns to its original position. However, the spring return feeding detection mechanism has a complex structure. After it reaches the end of its impact life and is damaged, it is difficult to disassemble and repair, and the cost is high. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an automatic feeding detection mechanism which is convenient to disassemble and maintain and has low cost.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A feeding automatic detection mechanism, comprising:

[0006] The base is mounted on the continuous stamping die, and a 7-shaped swing groove is provided on the base. The swing groove includes a first limit groove arranged horizontally and a second limit groove arranged vertically;

[0007] The pendulum block is in the shape of a figure 7 and is adapted to the pendulum slot. The pendulum block includes an upper pendulum portion and a lower pendulum portion. A rotating shaft is provided through the front end of the upper pendulum portion. The rotating shaft is detachably fixed between the front end side walls of the first limiting slot. The upper pendulum portion is rotatably connected to the rotating shaft, and a metal part to be measured is provided at the rear end of the upper pendulum portion. Before the material belt is in place, the pendulum block swings counterclockwise around the axis of the rotating shaft due to gravity, and the bottom of the rear end of the upper pendulum portion presses on the first limiting slot, and the lower pendulum portion is away from the second limiting slot. When the material belt is in place, the material belt pushes the pendulum block to swing clockwise around the axis of the rotating shaft, and the rear end of the lower pendulum portion presses on the second limiting slot, and the rear end of the upper pendulum portion is away from the first limiting slot.

[0008] The inductive sensor is detachably fixed on the base through a mounting base and is located at the rear end of the first limiting groove, and is used to detect the position of the metal part to be measured.

[0009] In some embodiments, the mounting base includes an integrally connected mounting plate and a connecting ear. The mounting plate is provided with a connecting screw that is threadedly connected to the base. The connecting ear is provided with a first screw hole; the inductive sensor is threadedly connected to the first screw hole. In at least one embodiment, the inductive sensor is perpendicular to the pendulum block, and the sensing end of the inductive sensor is close to the metal part being measured.

[0010] Compared with the prior art, the present invention achieves at least the following beneficial effects:

[0011] The metal part to be measured in the utility model follows the movement of the pendulum block, and the pendulum block will be pushed by the material belt and swing clockwise around the axis of the rotating shaft. When the material belt is in place, the rear end of the lower pendulum part presses on the second limit groove, and the rear end of the upper pendulum part is away from the first limit groove. The inductive sensor can automatically detect the position and movement trajectory of the metal part to be measured to determine whether the material belt is fed into place. When the material belt is in place, the inductive sensor outputs an electrical signal to the continuous feeding mechanism, and the continuous feeding mechanism performs corresponding start and stop actions according to the electrical signal, thereby realizing accurate feeding of the material belt product, and can perform continuous automatic stamping work in conjunction with the stamping die to improve production efficiency. The utility model has a simple structure and low cost. The rotating shaft on the pendulum block is detachably fixed between the front end side walls of the first limit groove, and the inductive sensor is detachably fixed on the base through a mounting seat. The pendulum block and the inductive sensor can be easily disassembled and maintained. BRIEF DESCRIPTION OF THE DRAWINGS
