Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5 The utility model discloses an aluminum alloy die-casting punching device with a compound device, including a workbench 10, a bracket 20 is fixedly installed on the top surface of the workbench 10, a cylinder 30 is bolted to the top surface of the bracket 20, a punching head mounting seat 40 is fixedly installed at the bottom output end of the cylinder 30, a first slide groove 50 is provided on the top surface of the workbench 10, a movable platform 60 slidably connected to the first slide groove 50 is provided, a tooth groove 70 is provided on the top surface of the movable platform 60, long grooves 80 are provided on the inner walls of both sides of the bracket 20, a groove is provided on one side of the bracket 20, a compound device 90 is provided in the groove, a long opening 100 is connected to the long groove 80, and a pushing mechanism 200 is fixedly installed at the output end of the cylinder 30.

[0021] The definition of the compound device 90 in this application is: a structure (or device) that can realize multiple functions, for example: the movable platform 60 can be driven to move equidistantly by the recovery of the cylinder 30, and the displacement of the movable platform 60 for each equidistant movement can be adjusted, which can reduce the workload of the staff and improve the efficiency. The structure is relatively simple and does not require the use of an intelligent controller.

[0022] Specifically, the pushing mechanism 200 includes a lifting slide 210, which is welded to the output end of the cylinder 30. The two ends of the lifting slide 210 are respectively connected to the two long grooves 80 for up and down sliding. One end of the lifting slide 210 is integrally connected with an extended push piece 220, which passes through the long opening 100 and extends into the groove.

[0023] In this embodiment, the entire pushing mechanism 200 can move up and down together with the output end of the cylinder 30, which can improve the stability of the punching head mounting base 40 when it moves up and down, and at the same time can push the moving bar 96 upward, thereby driving the rack 94 to move upward, so that it can be used in conjunction with the compound device 90.

[0024] Specifically, the compound device 90 includes a pair of toothed pulleys 91 distributed up and down, a synchronous toothed belt 92 is connected between the two toothed pulleys 91, a gear 93 is connected to the center of the rear end of the two toothed pulleys 91, the gear 93 and the toothed pulleys 91 are rotatably connected to the front and rear inner wall axes of the groove, wherein the lower gear 93 is meshed with the tooth groove 70, wherein the other side of the upper gear 93 is meshed with a rack 94, the front face of the rack 94 is provided with a second slide groove 95, and the second slide groove 95 is provided with a moving bar 96 connected to the second slide groove 95 and the moving bar 96 is connected to the second slide groove 95. It is a hollow aluminum alloy structure with a bracket inside. It is light in weight and high in strength. At the same time, its bottom is threadedly connected to a round rubber pad, which can play a buffering role and is easy to replace. A screw clamping device 97 is installed on the front of the rack 94. A baffle 98 is provided in the groove, which is connected to the front and rear inner walls of the rack for sliding up and down. The upper and lower inner wall axes of the groove are connected to the screw 99, and the baffle 98 is threadedly connected to the screw 99. The bottom end of the moving bar 96 is attached to the top surface of the baffle 98, and the extended push piece 220 is located directly below the moving bar 96. A switch 300 is screwed on the lower side of the other side of the moving bar 96.

[0025] In this embodiment, the compound device 90 can be used in conjunction with the pushing mechanism 200, and can drive the movable platform 60 to move during the recovery of the cylinder 30 (the recovery of the cylinder 30 is slower when it is relatively extended), and the spacing of each movement of the movable platform 60 is the same, so as to facilitate the straight and equidistant punching of the aluminum alloy die-casting parts. There is no need to manually push the movable platform 60 to move, which can reduce the workload of the staff and the need to set up a more intelligent pushing device (with PLC), which can effectively reduce the manufacturing and use costs.

[0026] Specifically, scale lines are engraved on the front and rear inner walls of the groove and the top surface of the workbench 10 .

[0027] In this embodiment, it is convenient for the staff to grasp the position of the baffle 98, thereby facilitating adjustment of the spacing between two adjacent punching holes, and convenient for the staff to grasp the position of the movable platform 60, and convenient for the staff to reset the movable platform 60, thereby facilitating subsequent normal use.

[0028] Specifically, a plurality of positioning holes 400 are formed on the top surface of the movable platform 60 , and the width of the upper end of the movable platform 60 is smaller than the width of the lower end thereof.

[0029] In this embodiment, the specific shape of the movable platform 60 is disclosed, and the positioning card hole 400 provided at the same time can be used to fix the aluminum alloy die-casting mold, thereby facilitating the positioning card to the aluminum alloy die-casting to be punched, and can effectively ensure the punching quality of the subsequent aluminum alloy die-casting.

[0030] The working principle and use process of the present invention are as follows: according to the positions of multiple equally spaced punching holes on the aluminum alloy die-casting, the starting position of the movable platform 60 is adjusted, and at the same time, the height of the blocking bar 98 is adjusted by rotating the screw 99. In normal use, the output end of the cylinder 30 will drive the punching head to move down and punch the aluminum alloy die-casting, and then slowly retract. At this time, the extended push piece 220 moves up together, and the extended push piece 220 first contacts the switch 300. At this time, the screw clamping device 97 automatically starts and clamps and tightens the movable bar 96. The movable bar 96 is fixedly connected to the rack 94. The extended push piece 220 continues to move up and drives the movable bar 96 to move up. The movable bar 96 and the rack 94 move up together (the cylinder 30 recovers the same displacement each time). At this time, the rack drive 94 drives the upper gear 93 to rotate. Under the transmission connection of the toothed pulley 91 and the synchronous toothed belt 92, the lower gear 93 rotates accordingly and drives the movable platform 60 containing the tooth groove 70 to move. The output end of the cylinder 30 moves down again for punching. At this time, the switch 300 squeezes it, and the screw clamping device 97 automatically resets. The movable bar 96 loses its clamping and automatically moves down under the action of gravity until it contacts the baffle 98. Since the horizontal height of the bottom end of the baffle 98 is consistent, the movable platform 60 moves with the same displacement each time.
