[0019] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the following.

[0020] Reference Figure 1-3 As shown, a die casting burr punching device comprises a box body 1, a punching mechanism 2 arranged on the top of the box body 1, and a crushing mechanism 3 arranged on both sides of the box body 1;

[0021] The crushing mechanism 3 includes a shell 31 fixedly mounted on both sides of the box body 1, a feeding rectangular cylinder 32 fixedly mounted on the bottom of the shell 31, two crushing rollers 33 relatively movably connected inside the shell 31, and a motor 36 fixedly mounted on one side of the shell 31. One end of the two crushing rollers 33 movably penetrates the shell 31 and is fixedly connected with a synchronous wheel 35. The synchronous wheels 35 are meshed and connected by a synchronous belt. The output end of the motor 36 is fixedly connected to the axis of the synchronous wheel 35. The bottom end of the feeding rectangular cylinder 32 extends to the inside of the box body 1. An arc baffle 34 is fixedly mounted on one side of the top of the shell 31.

[0022] An infrared sensor 37 is fixedly mounted on one side of the inner side of the housing 31 , and the infrared sensor 37 is electrically connected to the motor 36 via a controller.

[0023] The utility model provides a die-casting burr punching device, which is used to punch the burrs of the die-casting through the punching mechanism 2. The punched burrs will fall into the interior of the shell 31. When the infrared sensor 37 senses the burrs falling into the interior of the shell 31, the information is transmitted to the controller, and the controller controls the motor 36 to start, and the motor 36 drives the synchronous wheel 35 to rotate. Under the action of the synchronous belt, the two crushing rollers 33 are linked to rotate together inside the shell 31 to crush the punched burrs. The crushed burrs are leaked to the interior of the box 1 through the feeding rectangular tube 32 for collection, which effectively avoids the punched burrs from accumulating on the workbench, thereby improving the working efficiency of the die-casting burr punching.

[0024] The arc-shaped baffle plate 34 is used to block the burrs cut off by punching, thereby effectively preventing the burrs cut off by punching from being pumped outward.

[0025] Optionally, the punching mechanism 2 includes a driven rod 21 fixedly installed at the four corners of the top of the box body 1, a fixed plate 22 fixedly connected to the top of the driven rod 21, and a hydraulic rod 23 passing through and fixedly installed at the top center of the fixed plate 22. The punching mechanism 2 also includes a base 26 fixedly installed on the top of the box body 1, a stamping plate 24 movably connected to the outer wall of the driven rod 21, and a burr punching die 25 fixedly installed at the bottom of the stamping plate 24. The top of the stamping plate 24 is fixedly connected to the output end of the hydraulic rod 23.

[0026] Specifically, the die casting is placed on the base 26. After placement, the hydraulic rod 23 is started, and the hydraulic rod 23 drives the stamping plate 24 to move downward. The stamping plate 24 is linked to slide on the hydraulic rod 23, so that the burr cutting die 25 contacts and cuts the die casting, thereby achieving the purpose of burr cutting of the die casting.

[0027] Furthermore, a drawout slot 4 is provided on one side of the box body 1 , a collection box 5 is slidably connected inside the drawout slot 4 , and a handle 6 is fixedly installed on one side of the collection box 5 .

[0028] Specifically, by pulling the handle 6 outward, the collection box 5 is linked to slide inside the drawer groove 4, so as to draw the collection box 5 out from the inside of the box body 1, so as to facilitate cleaning of the burrs and debris collected inside the collection box 5.

[0029] Furthermore, universal wheels 7 are provided at the four corners of the bottom of the box body 1, and two fixed blocks 8 are relatively fixedly installed on the front and rear sides of the box body 1. A screw rod 9 movably penetrates the top of the two fixed blocks 8, and a hand-tightening block 10 is fixedly connected to the top of the screw rod 9, and a floor mat 11 is fixedly connected to the bottom end of the screw rod 9.

[0030] Specifically, by arranging universal wheels 7 at the four corners of the bottom of the box body 1, the device can be easily moved at will. When the device is moved to the installation position, the hand-tightening block 10 is manually rotated, and the linkage screw 9 is threadedly rotated on the fixed block 8, so that the floor mat 11 is in contact with the ground, which is used to fix and support the device moved to the installation position, thereby improving the stability of the device during use.

[0031] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
