Description

Technical Field

[0001] This utility model relates to the field of cold heading machines, specifically to a device for detecting material detachment. Background Technology

[0002] During the operation of a cold heading machine, wear of the mold, displacement of the punch, or unexpected deformation of the product may cause the product to be carried out of the mold by the punch. If processing continues in this case, the punch may break or the mold may be damaged. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an anti-material stripping detection device, including a swing arm, a sensor, and a transmission mechanism. The swing arm is mounted on a cold heading machine, the sensor is mounted at the end of the swing arm, and the transmission mechanism connects the swing arm to the main shaft of the cold heading machine so that the swing arm swings as the main shaft of the cold heading machine rotates.

[0004] Preferably, the transmission mechanism includes a drive shaft and a cam. The drive shaft is mounted on the cold heading machine and connected to the main shaft of the cold heading machine. The cam is mounted on the drive shaft, and an elastic element is connected to the swing arm so that one end of the swing arm fits against the cam.

[0005] Preferably, the swing arm is equipped with rollers, and after assembly, the rollers are in contact with the cam.

[0006] Preferably, the elastic element is a spring or a torsion spring.

[0007] Preferably, it also includes a cylinder, a seat plate, and a guide structure for guiding the swing arm. The cylinder is mounted on the cold heading machine, the seat plate is mounted on the cold heading machine and connected to the output end of the cylinder, the swing arm is mounted on the seat plate, and the guide structure is disposed between the cold heading machine and the swing arm.

[0008] Preferably, a pivot is mounted on the seat plate, a swing arm is mounted on the pivot, and the elastic element is a torsion spring. The torsion spring is sleeved on the pivot, with one end abutting against the swing arm and the other end abutting against the seat plate.

[0009] The beneficial effects of this utility model are as follows: The transmission mechanism draws out the power of the cold heading machine spindle, drives the swing arm to swing, and moves the sensor to the detection position to detect whether a product is carried out by the punch. If the product is detected to be carried out, the control process can be taken to stop the equipment or take other measures to avoid damage to the mold and punch. Attached Figure Description

[0010] Figure 1 This is a structural diagram showing the combination of this utility model and a cold heading machine;

[0011] Figure 2 This is an overall structural diagram of the present invention. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0013] Please see Figures 1-2 This utility model provides an anti-material slippage detection device, including a swing arm 1, a sensor 2 and a transmission mechanism. The swing arm 1 is installed on a cold heading machine, the sensor 2 is installed at the end of the swing arm 1, and the transmission mechanism connects the swing arm 1 to the main shaft of the cold heading machine so that the swing arm 1 swings with the rotation of the main shaft of the cold heading machine.

[0014] During operation, the transmission mechanism draws power from the cold heading machine's spindle, causing the swing arm 1 to swing and move the sensor 2 to the detection position. This sensor detects whether a product is being carried out by the punch. If product is detected, the control process can be initiated to stop the machine, thus preventing damage to the mold and punch. Clearly, detecting product carry-out is a critical step in this process. After detection, the swing arm 1 moves the sensor 2 away, preventing it from interfering with the cold heading process. The swing arm 1 is linked to the spindle via the transmission mechanism, synchronizing its movement with the cold heading machine's processing actions, facilitating coordinated control and ensuring more stable operation.

[0015] Furthermore, the transmission mechanism includes a drive shaft 31 and a cam 32. The drive shaft 31 is mounted on the cold heading machine and connected to the main shaft of the cold heading machine. The cam 32 is mounted on the drive shaft 31. An elastic element 33 is connected to the rocker arm 1 so that one end of the rocker arm 1 is in contact with the cam 32. The elastic element 33 is a spring or a torsion spring.

[0016] A pivot 51 is mounted on the seat plate 5, and a swing arm 1 is mounted on the pivot 51. The elastic element 33 is a torsion spring, which is sleeved on the pivot 51, with one end abutting against the swing arm 1 and the other end abutting against the seat plate 5.

[0017] The drive shaft 31 is connected to the main shaft of the cold heading machine and receives power. A spring, torsion spring, or other elastic element 33 pushes one end of the swing arm 1 to fit against the cam 32. When the drive shaft 31 drives the cam 32 to rotate, the cam 32 drives the swing arm 1 to swing, thereby causing the sensor 2 to swing to or move out of the detection position. The structure of the cam 32 and drive shaft 31 drives the swing arm 1, which is simple and easy to cooperate with the main shaft of the cold heading machine.

[0018] Furthermore, a roller 34 is installed on the rocker arm 1. After assembly, the roller 34 fits into the cam 32, reducing the friction between the cam 32 and the rocker arm 1.

[0019] Furthermore, it also includes a cylinder 4, a seat plate 5, and a guide structure for guiding the swing arm 1. The cylinder 4 is mounted on the cold heading machine, the seat plate 5 is mounted on the cold heading machine and connected to the output end of the cylinder 4, the swing arm 1 is mounted on the seat plate 5, and the guide structure is set between the cold heading machine and the swing arm 1.

[0020] A guide structure consisting of a slider and a groove can be installed between the cold heading machine and the swing arm 1, or the guide structure can be set as a sliding sleeve and a guide rod. During operation, the cylinder 4 pushes the seat plate 5, thereby pushing the swing arm 1 and the sensor 2 closer to the detection position; in this way, the swing amplitude of the swing arm 1 can be reduced, avoiding the swing being affected by other parts of the cold heading machine.

[0021] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
