[0022] like Figure 2As shown, the utility model includes a product collection structure for a die device, which includes: a material collection channel arranged below a cutting station 1 - 3 , a lower die base 1 - 1 , a joint base 3 and a quick-change joint 5 .

[0023] like Figure 3 and Figure 4 As shown, the joint base 3 includes a base body 3-1 and a circular tubular inner cavity 3-2. The joint base 3 is vertically arranged above the material collection channel with its opening upward, and a spring pin 4 is horizontally arranged in the inner cavity of the joint base 3; the spring pins 4 are arranged in pairs, and each pair of rolling spring pins 4 is arranged on the same diameter; the pin head at the top of the spring pin 4 protrudes from the inner cavity side wall of the joint base 3 and faces the center of the horizontal cross section of the joint base 3 where it is located.

[0024] The spring pin 4 is implemented based on the spring pin structure in the prior art, and can be a cylindrical pin or a spherical pin. In this embodiment, the spring pin 4 is implemented based on a ball spring pin, such as Figure 3 As shown, the ball spring pin includes: a housing 4-1, a wire spring 4-2 and a ball 4-3, one end of the wire spring 4-2 is fixedly connected to the ball 4-2, a cylindrical cavity is arranged in the center of the housing 4-1, the outlet of the cylindrical cavity is a gradual arc closing, the outermost outlet diameter is smaller than the diameter of the ball 4-3, the wire spring 4-2 and the ball 4-3 are arranged in the cylindrical cavity, the outermost arc surface of the ball 4-3 protrudes from the outlet of the cylindrical cavity, and the wire spring 4-2 is in a compressed state. When the spring pin 4 is installed in the inner cavity of the joint base 3, the ball 4-3 protrudes from the inner cavity side wall of the joint base 3.

[0025] The quick-change connector 5 is barrel-shaped, and its outer diameter is adapted to the inner diameter of the connector base 3, ensuring that it can be inserted into the inner cavity of the connector base 3. At the same time, a card slot 5-1 is provided on the outer side wall of the quick-change connector 5, and the shape and size of the card slot 5-1 are adapted to the pin head at the top of the spring pin 4; when the quick-change connector 5 is inserted into the inner cavity of the connector base 3 from bottom to top, based on the cooperation of the card slot 5-1 and the ball spring pin 4, the quick-change connector 5 is installed at the bottom of the inner cavity of the connector base 3 from bottom to top.

[0026] A vacuum suction hose (not marked in the figure) is arranged at the lower part of the quick-change joint 5 which is not inserted into the inner cavity of the joint base 3, and the suction port of the vacuum suction hose faces the material collection channel. The vacuum suction hose of the present application can be realized based on the vacuum suction telescopic hose in the prior art, and the vacuum suction hose is connected to the negative pressure device to realize the suction of the product.

[0027] In order to ensure the installation stability of the quick-change connector 5 and the connector base 3 , the present application also provides a limit clamp ring 5 - 2 on the quick-change connector 5 .

[0028] like Figure 5In the illustrated embodiment, the top of the quick-change connector 5 is the access end, and the outer diameter of the access end is adapted to the inner cavity diameter of the connector base 3; the limiting clamp ring 5-2 and the clamping groove 5-1 are arranged on the outer circumference of the access end of the quick-change connector 5, and the limiting clamp ring 5-2 is located below the clamping groove 5-1; the outer diameter of the limiting clamp ring 5-2 is larger than the inner cavity diameter of the connector base 3; the distance between the upper end face of the limiting clamp ring 5-2 and the clamping groove 5-1 is adapted to the distance between the bottom end face of the connector base 3 and the spring pin 4. By setting the limiting snap ring 5-2, in actual operation, the operator pushes the quick-change connector 5 into the bottom of the connector base 3 from bottom to top. After the ball spring pin 4 is inserted into the slot, due to the existence of the limiting snap ring 5-2, the relative position of the quick-change connector 5 and the connector base 3 will no longer change, and the problem of damaging the slot and the spring pin due to excessive force will not occur; at the same time, in actual operation, if the quick-change connector 5 is accidentally subjected to horizontal force, due to the existence of the limiting snap ring 5-2, it can be in stable contact with the bottom end surface of the connector base 3, reducing the probability of the spring pin and the slot falling off due to unexpected force.

[0029] like Figure 4 and Figure 6 As shown, in this embodiment, the joint base 3 is arranged in the lower die base 1-1. 1-12 is a screw for connecting the joint base 3 with the lower die base, and 1-13 is a pin for connecting the joint base 3 with the lower die base. During specific installation, the joint base 3 is first fixed in the installation cavity 1-11 in the lower die base 1-1, and then the lower die base is installed on the cutting station 1-3 on the machine tool 1. The material collection channel is located below the lower die base 1-1. Finally, the quick-change joint 5 is inserted from bottom to top into the joint base 3 to complete the assembly of the product collection structure. After the product is cut by the cutting structure (not marked in the figure) on the cutting station, the product falls from the clamping part 1-2 and falls into the material collection channel below the cutting station 1-3 of the punch press. It is directly sucked away by the vacuum suction hose set at the bottom of the quick-change joint 5, without the need for manual sorting by the operator, which greatly improves the product collection efficiency.
