Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a feeding and detection device for sheet metal processing. Background Technology

[0002] Sheet metal parts are mostly produced by stamping. The sheet metal is fed to the bottom of the stamping die by a feeder. However, during the stamping process, feeding too much or too little sheet metal can cause misalignment and damage to the die. In the existing technology, the amount of sheet metal fed is limited by a stop or a stopper. The stop can only prevent excessive feeding, but it cannot prevent insufficient feeding. During stamping, it can still cause die damage or product defects, which is not very practical. Therefore, this utility model proposes a feeding detection device for sheet metal processing. Utility Model Content

[0003] The main objective of this invention is to provide a feeding and inspection device for sheet metal processing, in order to solve the mold problem mentioned in the background art.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a feeding detection device for sheet metal processing, comprising a power supply, a current sensor, and a trigger switch assembly connected in a loop by wires, the trigger switch assembly facing the material feeding direction, the current sensor connected to a control panel, the trigger switch assembly including an insulating base, a first metal base and a second metal base fixed on the insulating base, a protrusion on the side of the first metal base facing the second metal base, a first metal spring and a second metal spring respectively provided on the side of the protrusion and the second metal base opposite to each other, the first metal spring being in close contact with the front of the second metal spring, an insulating dividing line vertically provided on the second metal spring, and one end of the first metal spring being located on the side of the insulating dividing line away from the second metal base.

[0005] Preferably, the first metal base and the second metal base are connected to the circuit via wires.

[0006] Preferably, the bottom end of the first metal spring is higher than the bottom end of the second metal spring.

[0007] Preferably, the insulating separator line is formed by laser ablation.

[0008] The beneficial effects of this utility model are as follows: by setting a trigger switch component in the current circuit, the trigger switch component is triggered when the material is fed into place, and the current signal in the detection circuit is used to determine whether the material is in place; when the material is fed insufficiently or excessively, the trigger switch component cannot be triggered and the circuit is in an open state, thereby ensuring that both insufficient and excessive feeding can be detected, thus enhancing practicality.

[0012] The present invention will be further described in detail below with reference to specific embodiments.

[0013] Example: like Figure 1 and Figure 2As shown, this utility model discloses a feeding detection device for sheet metal processing, comprising a power supply 1, a current sensor 2, and a trigger switch assembly 3 connected in a circuit via wires. The trigger switch assembly 3 faces the direction of material feeding. The current sensor 2 is connected to a control panel 4, which is electrically connected to a stamping machine for controlling the start and stop of the stamping machine. The trigger switch assembly 3 includes an insulating base 5, on which a first metal base 6 and a second metal base 7 are fixed. A gap is left between the opposite sides of the first metal base 6 and the second metal base 7. A protrusion 8 is provided on the side of the first metal base 6 facing the second metal base 7. A first metal spring 9 and a second metal spring 10 are respectively provided on the opposite sides of the protrusion 8 and the second metal base 7. The first metal spring 9 is in close contact with the front side of the second metal spring 10. An insulating separator line 11 is vertically provided on the second metal spring 10, and one end of the first metal spring 11 is located at the insulating separator line. When the wire 11 is away from the side of the second metal seat 7, the first metal spring 9 and the second metal spring 10 are disconnected. The feeder feeds the sheet. If the sheet is not fed into position, it does not contact the second metal spring 10, the circuit is open, the current sensor 2 does not detect the current, and the control panel 4 controls the press to stop. If the sheet is fed into position, the end of the sheet just contacts the second metal spring 10, and the sheet connects the two sides of the insulation separator 11 of the second metal spring 10, thereby connecting the first metal spring 9 and the second metal spring 10, the circuit is connected, the current sensor 2 detects the current and sends a signal to the control panel 4, and the control panel 4 controls the press to perform the stamping operation. If the sheet is fed too much, the end of the sheet pushes the second metal spring 10 backward, causing the second metal spring 10 to separate from the first metal spring 9, the circuit is broken, the current sensor 2 does not detect the current, and the press does not work.

[0014] The first metal base 6 and the second metal base 7 are connected to the circuit via wires.

[0015] The bottom end of the first metal spring 9 is higher than the bottom end of the second metal spring 10.

[0016] The insulating separator line 11 is formed by laser ablation.

[0017] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
