Description

Technical Field

[0001] The utility model relates to the technical field of waste collection of a continuous stretching stamping machine, in particular to a waste collection device for a stamping machine. Background Art

[0002] The outer shell of a lithium battery is usually formed by multiple stretchings using a continuous stretching die. The current stamping machine performs the final stretching of the lithium battery outer shell at the last cutting station, and cuts off the excess material on the lithium battery outer shell through the tool on the punch head of the stamping machine. However, the cut waste will be sleeved on the punch head of the stamping machine. To ensure the normal operation of the subsequent punch head of the stamping machine, currently, an air nozzle is used to blow off the waste on the punch head of the stamping machine. However, there is a situation where the waste does not completely separate from the punch head of the stamping machine, which may lead to equipment shutdown. At the same time, the blown waste will be scattered near the cutting station of the stamping machine, and on-site personnel need to perform regular cleaning. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a waste collection device for a stamping machine, which can ensure the effective separation of waste from the punch head of the stamping machine and collect the waste in an orderly manner.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a waste collection device for a stamping machine, including a punch press body, a waste hopper and a fixture; the punch press body successively has a cutting station and a waste station along the stamping process direction, the feeding end of the waste hopper is located at the waste station, and the fixture reciprocates between the cutting station and the feeding end of the waste hopper.

[0005] Further, the fixture includes two oppositely arranged movable arms and a clamping part arranged on the movable arms. The cutting station and the waste station are located between the two movable arms. The movable arms have a first moving direction and a second moving direction. The first moving direction is parallel to the stamping process direction of the punch press body, and the second moving direction is perpendicular to the stamping process direction of the punch press body.

[0006] Further, a receiving platform is arranged at the feeding end of the waste hopper, and the fixture reciprocates between the cutting station and the receiving platform.

[0007] Further, the clamping part includes an assembly plate and a clamping block; the assembly plate is connected to the movable arm, the assembly plate has an assembly long hole, and the clamping block is arranged on the assembly plate through the assembly long hole.

[0008] Further, the clamping part includes an assembly plate and a clamping block; the assembly plate is connected to the movable arm, the assembly plate has a plurality of assembly holes, and the clamping block is arranged on the assembly plate through the assembly holes.

[0009] Further, a groove is provided on the clamping end face of the clamping block.

[0010] Further, the waste collection device of the punching machine further includes a waste conveyor belt, and the waste conveyor belt is located below the discharge end of the waste hopper.

[0011] The beneficial effects of the present utility model are as follows: Different from the prior art, a waste station is added after the cutting station of the punching machine body, and the feeding end of the waste hopper is placed at the waste station. At the same time, a fixture that can reciprocate between the cutting station and the feeding end of the waste hopper is added. During the process of collecting waste, the fixture moves to the cutting station. When the punch of the punching machine rises and separates from the die, the fixture operates to clamp the waste sleeved on the punch of the punching machine, so that the waste cannot continue to move upward with the punch of the punching machine. Then the fixture clamps the waste and moves to the feeding end of the waste hopper. Finally, the waste is collected uniformly through the waste hopper. This cycle not only ensures the effective separation of the waste from the punch of the punching machine, but also prevents the waste from scattering around the cutting station of the punching machine body.

[0020] In order to describe in detail the technical content, the achieved purpose and the effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the drawings.

[0021] Please refer to Figure 1As shown in the figure, a waste collection device for a stamping machine of the present utility model includes a punching press body 1, a waste hopper 2 and a fixture 3; the punching press body 1 successively has a cutting station 11 and a waste station 12 along the stamping process direction, the feeding end of the waste hopper 2 is located at the waste station 12, and the fixture 3 reciprocates between the cutting station 11 and the feeding end of the waste hopper 2.

[0022] Working principle: During the process of collecting waste, the fixture 3 moves to the cutting station 11. When the punch 5 of the stamping machine rises and separates from the die, the fixture 3 operates to clamp the waste sleeved on the punch 5 of the stamping machine, so that the waste cannot continue to move upward with the punch 5 of the stamping machine. Then the fixture 3 clamps the waste and moves it to the feeding end of the waste hopper 2. Finally, the waste is collected uniformly through the waste hopper 2. This cycle not only ensures the effective separation of the waste from the punch 5 of the stamping machine, but also prevents the waste from scattering around the cutting station 11 of the punching press body 1.

[0023] In one embodiment, please refer to Figure 1 As shown in the figure, the fixture 3 includes two oppositely arranged movable arms 31 and a clamping portion 32 provided on the movable arms 31. The cutting station 11 and the waste station 12 are located between the two movable arms 31. The movable arms 31 have a first moving direction and a second moving direction. The first moving direction is parallel to the stamping process direction of the punching press body 1, and the second moving direction is perpendicular to the stamping process direction of the punching press body 1. The movable arms 31 are used to drive the clamping portion 32 to transfer the waste from the cutting station 11 to the feeding end of the waste hopper 2. Among them, for the specific movement mode of the movable arms 31, reference can be made to the three-axis stamping manipulator disclosed in the publication number CN103395060B, which includes a Y-axis lifting mechanism, an X-axis moving mechanism, a Z-axis moving mechanism and an arm rod mechanism. The X, Y, and Z axes are orthogonal three axes; the Y-axis lifting mechanism includes a lifting lead screw, a lifting lead screw nut and a main hanger; the X-axis moving mechanism includes a feeding lead screw, a feeding lead screw nut, a first X-axis slide rail mechanism, a push rod guide rod and a second X-axis slide rail mechanism; the Z-axis moving mechanism includes a Z-axis lead screw, a Z-axis lead screw nut, a clamping seat guide rod, a first Z-axis slide rail mechanism and a second Z-axis slide rail mechanism; the arm rod mechanism is used to mount or connect the manipulator.
