[0029] In actual use of this embodiment, the movable die 130 includes a die base 131 disposed above the fixed die 120 and a punch 132 disposed on the lower side of the die base 131, wherein the diameter of the punch 132 is adapted to the diameter of the punching hole so as to perform punching; wherein the top base 110 is provided with a cylinder 111 for driving the movable die 130 to rise and fall, thereby enabling the cylinder 111 to drive the punch 132 to rise and fall, and perform punching operation on the aluminum plate placed above the fixed die 120;

[0030] Among them, by setting the draw-out cavity 121 and the waste collection component, the waste collection component can be drawn out and set in the draw-out cavity 121, thereby collecting the waste generated by the aluminum shell punching die during the punching operation, and at the same time, it is convenient to discharge the collected waste;

[0031] Among them, by setting the pull-out box 210, the sliding cavity 211, the collection box 220 and the driving member, in actual use, the collection box 220 is placed in the sliding cavity 211, and the waste generated at the punching position can be collected. The collection box 220 is driven by the driving member to slide in the sliding cavity 211, so that the collection box 220 swings back and forth, thereby preventing the waste collected in the collection box 220 from piling up too high just below the punching hole, resulting in poor waste collection effect of the collection box 220, which affects the punching operation of the punching die;

[0032] Among them, through the setting of the fixing part, it is possible to fix the pull-out box 210 in the pull-out cavity 121, thereby preventing the pull-out box 210 from sliding in the pull-out cavity 121, resulting in the collection box 220 being unable to collect waste materials better. At the same time, it is possible to release the fixation of the pull-out box 210, so that the pull-out box 210 can be pulled out in the pull-out cavity 121 to discharge the collected waste materials.

[0033] Combination Figure 3 As shown, in this embodiment, a first cavity 212 is provided on the side wall of the pull-out box 210 extending into the pull-out cavity 121, and the driving member includes a movable plate 230 slidably arranged in the first cavity 212, and a push rod 231 is relatively provided on the movable plate 230. A first spring 232 is provided in the first cavity 212 for driving the movable plate 230 to drive the push rod 231 to extend into the sliding cavity 211 to push the collection box 220 forward. The driving member also includes a push rod 221 which is arranged on the front side wall of the collection box 220 and passes through the pull-out box 210 and extends out of the pull-out cavity 121. Pressing the push rod 221 is used to drive the collection box 220 to move backward.

[0034] In actual use of this embodiment, a blocking plate is provided at the opening of the first cavity 212, and the blocking plate is used to block the first cavity 212, so as to better realize the installation of the movable plate 230 and the first spring 232 in the first cavity 212;

[0035] The push rod 231 is arranged to penetrate the movable plate 230, so that one end of the first spring 232 can be sleeved on one end of the push rod 231, and the other end abuts against the blocking plate, so that the first spring 232 can be installed in the first cavity 212 preferably. At the same time, the first spring 232 can drive the other end of the push rod 231 to extend into the sliding cavity 211, thereby pushing the collection box 220 forward. At this time, the push rod 221 is extended out of the pull-out box 210, so that the operator presses the push rod 221 to compress the first spring 232 and drive the collection box 220 to move backward. At this time, the push rod 221 is released, and the push rod 221 is reset under the action of the first spring 232. As a result, the operator can reciprocate by pressing the push rod 221 to drive the collection box 220 to reciprocate in the sliding cavity 211, thereby realizing the shaking of the collection box 220 in the sliding cavity 211, avoiding the accumulation of collected waste.

[0036] In actual use, in order to improve the waste collection effect of the collection box 220, the side wall of the collection box 220 and the top wall of the pull-out cavity 121 are slidably fitted together, thereby better avoiding waste being stuck in the gap between the two, resulting in poor waste collection effect of the collection box 220.

[0037] Combination Figure 4 and Figure 5 As shown, in the present embodiment, positioning holes 201 are provided on the opposite side walls of the pull-out cavity 121; the front side wall of the pull-out box 210 is provided with a second cavity 213 for the push rod 221 to pass through, and the fixing member includes a positioning pin member relatively and slidably arranged in the second cavity 213, one end of the positioning pin member extends through the pull-out box 210 and is inserted into the corresponding positioning hole 201 for fixing the pull-out box 210 in the pull-out cavity 121.

[0038] In actual use of this embodiment, a sealing plate 510 is provided at the opening of the second cavity 213, thereby enabling the positioning pin to be installed in the second cavity 213;

[0039] Among them, through the setting of the positioning pin and the positioning hole 201, when one end of the positioning pin extends out of the pull-out box 210 and extends into the corresponding positioning hole 201, the pull-out box 210 can be fixed in the pull-out cavity 121 to collect waste. When one end of the positioning pin is retracted into the pull-out box 210, the cooperation with the corresponding positioning hole 201 is released, so that the pull-out box 210 can be pulled out of the pull-out cavity 121, thereby facilitating the discharge of the collected waste.

[0040] In this embodiment, the positioning pin member includes a sliding block 240 slidably arranged in the second cavity 213, the sliding block 240 is provided with a positioning rod 311 that extends through the pull-out box 210, the positioning rod 311 is sleeved with a second spring 410 for driving the sliding block 240 to approach each other, a turntable 420 sleeved on the outside of the push rod 221 is provided in the second cavity 213, the sliding block 240 is provided with an abutment rod 411 for abutting against the side wall of the turntable 420 to realize the extension of the positioning rod 311, the side wall of the turntable 420 is provided with a groove 421 for the corresponding abutment rod 411 to extend into to realize the retraction of the positioning rod 311, and the side wall of the groove 421 is provided with a guide slope 422 for the abutment rod 411 to slide out.

[0041] By the structure of this embodiment, in actual use, by rotating the rotary disk 420, the abutting rod 411 slides into the groove 421 along the guide inclined surface 422 under the action of the second spring 410, and the positioning rod 311 extending out of the pull-out box 210 can be retracted, and the cooperation between the positioning rod 311 and the corresponding positioning hole 201 can be released. At this time, the pull-out box 210 can be drawn out of the pull-out cavity 121, which is convenient for the discharge of the waste collected by the waste collection assembly. By rotating the rotary disk 420, the abutting rod 411 slides out of the groove 421 along the guide inclined surface 422, thereby compressing the second spring 410, and the positioning rod 311 extends out of the pull-out box 210 and is inserted into the corresponding positioning hole 201, so that the pull-out box 210 is fixed in the pull-out cavity 121, so that it can collect waste;

[0042] In order to prevent the rotary disk 420 from rotating in error and causing the abutment rod 411 to slide into the corresponding groove 421 along the corresponding guide inclined surface 422, a hemispherical groove 521 for the abutment end of the corresponding abutment rod 411 to be inserted is provided on the side wall of the rotary disk 420, thereby limiting the abutment rod 411 so that it is not easy to slide relative to the outer wall of the rotary disk 420. At the same time, by using a large external force to drive the rotary disk 420 to rotate, the abutment rod 411 can slide out of the hemispherical groove 521, so as to adjust the telescopic position of the positioning rod 311.

[0043] In actual use, in order to facilitate the operator to drive the turntable 420 to rotate, a driving cylinder 430 is provided on the turntable 420, which is sleeved on the outside of the push rod 221 and extends through the pull-out box 210. Therefore, in order to better realize the installation of the driving cylinder 430 and the turntable 420 in the second cavity 213, the driving cylinder 430 passes through the sealing plate 510 and is rotatably provided on the sealing plate 510 through the bearing seat 320. Therefore, the rotation installation of the turntable 420 and the driving cylinder 430 is better realized; wherein, in order to facilitate the operator to drive the driving cylinder 430 to drive the turntable 420 to rotate, the protruding end of the driving cylinder 430 is provided with a dial post 431 for driving the driving cylinder 430 to rotate.

[0044] Working principle: the aluminum plate to be punched is placed on the fixed die 120, and the cylinder 111 is started to drive the punch 132 to rise and fall, so as to perform the punching operation on the aluminum plate. The waste generated by the punching operation can fall into the collection box 220 through the punching holes and be collected. After it has been collected for a period of time, the collection box 220 can be shaken in the sliding cavity 211 by repeatedly pressing and releasing the push rod 221, so as to avoid excessive accumulation of waste in the collection box 220 below the punching holes, thereby improving the collection effect of the collection box 220 in collecting waste. When the waste needs to be discharged, the drive cylinder 430 is driven to rotate by rotating the dial column 431, so that the turntable 420 rotates, and the abutment rod 411 slides into the corresponding groove 421 along the corresponding guide slope 422, so that the positioning rod 311 can be retracted, and its fixation to the pull-out box 210 is released, and the pull-out box 210 can be pulled out to discharge the waste.

[0045] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
