DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example: A punching machine material removal structure, such as Figure 1-Figure 4 As shown, it includes a machine platform 1, an adjusting foot 2, a gantry 3, a cylinder 4, a slide 5, a punching head 6, a punching part 61, a hinged rod 7, a pushing frame 8, a forming assembly and a ejecting assembly. The adjusting foot 2 is symmetrically connected to the left and right sides of the bottom of the machine platform 1, and the gantry 3 is connected to the top of the machine platform 1. The cylinder 4 is installed on the top of the gantry 3 by bolts. The slide 5 is symmetrically connected to the left and right sides of the inner upper side of the gantry 3. The punching head 6 is slidably connected between the slides 5. The telescopic rod of the cylinder 4 is connected to the punching head 6. The bottom of the punching head 6 is threadedly connected to the punching part 61 for punching the original part, and the punching part 61 is replaceable. The front side of the punching head 6 is symmetrically rotatably connected to the hinged rod 7. The pushing frame 8 is rotatably connected between the lower front sides of the slide 5. The pushing frame 8 can be rotated to push out the formed finished product. The hinged rod 7 is rotatably connected to the front side of the pushing frame 8. A forming assembly and an ejecting assembly are provided on the top of the machine platform 1.

[0023] like Figure 1 、 Figure 3 and Figure 4 As shown, the forming assembly includes a mounting seat 9, screws and nuts 91, a mold 10, a limit block 101 and a material guide frame 12. The mounting seat 9 is installed in the middle of the top of the machine 1 by bolts, and the mold 10 is installed on the mounting seat 9 by two left-right symmetrical screws and nuts 91. The mold 10 can be disassembled and replaced by the screws and nuts 91. The mold 10 is located directly below the stamping part 61. The front, back and left sides of the top of the mold 10 are connected with limit blocks 101 for limiting the position of the finished product original. The size between the limit blocks 101 is the size of the finished product original. A material guide frame 12 is installed on the rear side of the top of the machine 1 to facilitate the sliding and collection of the finished product. The material guide frame 12 is located on the rear side of the mounting seat 9 and is an oblique structure.

[0024] like Figure 3 and Figure 4 As shown, the ejection assembly includes an ejection block 11 and a return spring 111 . The ejection block 11 for ejecting the finished product is slidably connected to the mold 10 , and a return spring 111 is connected between the ejection block 11 and the inside of the mold 10 .

[0025] like Figure 5As shown, it also includes a slide rail 13, a discharge frame 14 and an electric push rod 15. The slide rail 13 is symmetrically connected to the front and back of the right side of the gantry 3. The distance between the two slide rails 13 is the width of the finished original, and the slide groove height of the slide rail 13 is the thickness of the finished original. A discharge frame 14 is connected between the top right sides of the two slide rails 13, and the finished originals are stacked in the discharge frame 14. An electric push rod 15 is installed on the upper right side of the machine 1 by bolts, and a push block is connected to the telescopic rod of the electric push rod 15. The top surface of the push block is consistent with the top surface of the slide rail 13. The telescopic rod of the electric push rod 15 is extended, and the push block can only push one finished original to move at a time.

[0026] When performing the stamping process of the finished product, the finished originals are first stacked in the discharge frame 14, and the finished original at the bottom is limited to the two slide rails 13. The electric push rod 15 is started, and its telescopic rod is extended, and the finished original at the bottom is pushed to the left by the push block. After the telescopic rod is reset, the remaining finished originals in the discharge frame 14 will slide down. Through such an operation, the finished original can be pushed to the left along the slide rail 13 intermittently. When the finished original is pushed onto the mold 10, the three limit blocks 101 can ensure that the finished original is in the center position. The electric push rod 15 can be used in conjunction with the cylinder 4. After each finished product is formed, the loading operation is performed again. At the beginning of the stamping work, the cylinder 4 is started, and its telescopic rod is extended, driving the punching head 6 and the punching part 61 to move downward. The punching head 6 will push the hinged rod 7 and the push frame 8 to rotate. The hinged rod 7 drives the push frame 8 to rotate forward along the slide 5, while the punching head 6 and the punching part 61 continue to move downward, and the punching part 61 will squeeze The finished product on the mold 10 is stamped, and the original is pressed to fit the shape of the mold 10 cavity. The original will extrude the top block 11 downward, and the return spring 111 is compressed accordingly. After the finished product is stamped and formed, the telescopic rod of the cylinder 4 is shortened and reset, driving the punching head 6 and the punching part 61 to move upward, and the punching part 61 is out of contact with the finished product, and the return spring 111 rebounds and resets, driving the top block 11 to move upward, and the top block 11 pushes the formed finished product to move upward. When the punching head 6 moves upward, it will drive the hinged rod 7 and the pushing frame 8 to reverse, and the hinged rod 7 drives the pushing frame 8 to rotate backward along the slide 5. Due to the increase in the height of the finished product after molding, the pushing frame 8 will contact the finished product during the process of rotating and resetting to the rear side, and then push the finished product out of the mold 10 to the rear side, so that the finished product slides along the guide frame 12 to realize automatic material removal. At this time, the above operation can be repeated, and the original is loaded by the electric push rod 15, and then stamped by the cylinder 4 to achieve continuous work and improve work efficiency.
