[0025] When the tool is in use, the sheet metal part is placed on the lower mold 12, and its two sides are located above the push plate 17. After the hole groove on the sheet metal part is punched out, the electric push rod 13 is started, and the electric push rod 13 drives the first push rod 15 and the second push rod 16 to move up, thereby pushing the push plate 17 up, thereby lifting the sheet metal part. After moving up to a certain height, the adjusting seat 26 on the vertical cylinder 21 of the first push rod 15 contacts the limit plate and cannot move up. Then the vertical rod 22 of the second push rod 16 continues to move up, and the vertical rod 22 of the first push rod 15 slides in the vertical cylinder 21. Then, as the vertical cylinder 21 of the second push rod 16 moves up, the second support 24 slides on the slide rail and lifts one side of the push plate 17, thereby making the push plate 17 tilt, relying on the tilt to make the sheet metal part slide, thereby sliding the sheet metal part to one side, thereby completing the sheet metal part stripping, thereby reducing the work steps of manual material stripping by the staff, thereby reducing the workload of the staff.

[0026] Further, such as Figure 2-4 As shown, the surface of the vertical cylinder 21 is provided with an external thread 31; the adjustment seat 26 is connected to the external thread 31 through a thread; when in use, the adjustment seat 26 connected to the external thread 31 on the vertical cylinder 21 can conveniently adjust the height of the vertical cylinder 21, so that the staff can adjust the height of the sheet metal and the tilt angle of the push plate 17 according to needs.

[0027] Further, such as Figure 4 As shown, a negative pressure groove 42 is provided on the top of the push plate 17; a hose 41 is fixed to the top of the vertical cylinder 21; the top of the hose 41 passes through the bottom of the negative pressure groove 42 and is connected to the negative pressure groove 42; the negative pressure groove 42 is located in the middle of the push plate 17; when in use, when the vertical rod 22 and the vertical cylinder 21 move downward to reset, the downward movement of the vertical rod 22 will form a negative pressure inside the vertical cylinder 21, thereby extracting the negative pressure groove 42 through the hose 41, thereby making the surface of the sheet metal fit on the push plate 17 , in order to fix it to a certain extent, when the push plate 17 moves up, the sheet metal is not easy to fall off. When the push plate 17 tilts, the vertical rod 22 continues to move up to push out the air in the vertical cylinder 21, thereby releasing the fixation. At this time, the push plate 17 is tilted, which can guide the sheet metal to be unloaded in one direction, and the blown air flow can reduce the friction between the sheet metal and the push plate 17, thereby reducing the possibility of sheet metal falling off when the push plate 17 moves up, making it easier to unload at a fixed point.

[0028] Further, such as Figure 4 As shown, a rubber pad 5 is fixed to the top of the negative pressure groove 42; an air inlet groove is opened at the position corresponding to the rubber pad 5 and the negative pressure groove 42; when in use, the rubber pad 5 is provided to improve the fit between the push plate 17 and the surface of the sheet metal, thereby improving the fixing effect of the negative pressure suction force.

[0029] Further, such as Figure 4 As shown, a filter screen 6 is fixedly connected to the interior of the negative pressure tank 42; the filter screen 6 is located at the top of the hose 41; when in use, due to the punching machine processing workshop, metal debris is generated, and the filter screen 6 is set to filter the air inhaled by the vertical cylinder 21, thereby reducing the possibility of the hose 41 being blocked.

[0030] Further, such as Figure 4 As shown, a rubber ring 7 is fixed to the top of the adjustment seat 26. When in use, the rubber ring 7 can buffer the contact between the adjustment seat 26 and the limit seat 25, thereby playing a protective role.

[0031] Working principle: when in use, the sheet metal is placed on the lower mold 12, and its two sides are located above the push plate 17. After the hole grooves on the sheet metal are punched out, the electric push rod 13 is started, and the electric push rod 13 drives the first push rod 15 and the second push rod 16 to move upward, so as to push the push plate 17 upward, thereby lifting the sheet metal. After moving up to a certain height, the adjustment seat 26 on the vertical cylinder 21 of the first push rod 15 contacts the limit plate and cannot move up. Then the vertical rod 22 of the second push rod 16 continues to move up, and the vertical rod 22 of the first push rod 15 slides in the vertical cylinder 21, and then The vertical cylinder 21 of the second push rod 16 moves upward, so that the second support 24 slides on the slide rail and lifts one side of the push plate 17, so that the push plate 17 tilts, and the sheet metal part slides down by relying on the tilt, so that the sheet metal part slides to one side, so as to complete the sheet metal part return, thereby reducing the staff's manual return work steps and thus reducing the staff's workload, relying on the adjustment seat 26 connected to the external thread 31 on the vertical cylinder 21, so as to facilitate the adjustment of the height of the vertical cylinder 21, so that the staff can adjust according to their needs. The height of the entire sheet metal part moving up and the angle of inclination of the push plate 17, when the vertical rod 22 and the vertical cylinder 21 move down to reset, the vertical rod 22 moves down to form a negative pressure inside the vertical cylinder 21, so as to extract the negative pressure groove 42 through the hose 41, and then make the surface of the sheet metal part fit on the push plate 17, so as to fix it to a certain extent. When the push plate 17 moves up, the sheet metal part is not easy to fall. When the push plate 17 is tilted, the vertical rod 22 continues to move up to push out the air in the vertical cylinder 21, so as to release the fixation. At this time, the push plate 17 is tilted, which can cause The sheet metal is guided to be withdrawn in one direction, and the blown air flow can reduce the friction between the sheet metal and the push plate 17, thereby reducing the possibility of sheet metal falling when the push plate 17 moves upward, and facilitating fixed-point unloading. The rubber pad 5 is provided to improve the fit between the push plate 17 and the surface of the sheet metal, thereby improving the fixing effect of the negative pressure suction. Since the punching machine processing workshop generates metal debris, the filter 6 is provided to filter the air inhaled by the vertical cylinder 21, thereby reducing the possibility of the hose 41 being blocked.
