[0037] A plurality of guide rods 22 are connected to both sides of the upper side wall of the fixed plate 2, and the plurality of guide rods 22 located on the same side of the fixed plate 2 are evenly arranged in a direction parallel to the length direction of the adjacent strip steel. A circumferential groove is provided at the upper side wall of each guide rod 22, and the strip steel can be simultaneously inserted into the grooves provided on the side walls of the plurality of guide rods 22. Each guide rod 22 is slidably inserted into the interior of the fixed plate 2 in the vertical direction, and a guide spring 221 is fixedly connected to the lower end of each guide rod 22, and one end of each guide spring 221 away from the connected guide rod 22 is fixedly connected to the inner wall of the opposite fixed plate 2.

[0038] In actual use, the steel strip is placed between the upper pressing plate 12 and the fixed plate 2, and then the cylinder 11 drives the movable plate 1 and the connected upper pressing plate 12 to move downward, and the cutting knife group 3 abuts against the steel strip to achieve cutting of the steel strip. After the cutting is completed, the cylinder 11 drives the movable plate 1 to move to the initial position. Then the steel strip is moved forward, and the cylinder 11 is started to drive the upper pressing plate 12 to abut against the fixed plate 2 again, so that the cutting knife group 3 abuts against the steel strip again, and the steel strip is cut by different cutting knives 31.

[0041] By setting the guide column 23 and the guide sleeve 231, during the downward movement of the upper pressure plate 12, the movable plate 1 can be sleeved onto the outside of the guide sleeve 231, so that the cutting knife group 3 connected to the movable plate 1 can abut against the preset position of the strip, making the cutting process more accurate.

[0042] A plurality of feeding holes 24 are formed on the fixed plate 2 , and each feeding hole 24 is formed corresponding to a cutting knife 31 connected to the movable plate 1 .

[0043] Reference Figure 2 and Figure 3 A plurality of receiving bins 4 are provided on the lower side of the fixed plate 2, and each receiving bin 4 has an opening on one side facing the feeding hole 24 for the debris at the feeding hole 24 to enter the receiving bin 4. A discharge port 41 is provided on one side of each receiving bin 4.

[0044] Each material receiving bin 4 is provided with a pushing assembly 5 , which can push the processing debris inside the material receiving bin 4 out of the material receiving bin 4 through the discharge port 41 .

[0045] When the cutting blade group 3 cuts the strip steel, the cut debris falls from the discharge hole 24 into the receiving bin 4, and then the pushing assembly 5 pushes the debris inside the receiving bin 4 out of the receiving bin 4 from the discharge port 41, thereby completing the cleaning process of the cut debris.

[0046] The material pushing assembly 5 includes a material receiving hopper 51 located inside the material receiving bin 4, and the outer wall of the material receiving hopper 51 is vertically slidably abutted against the inner wall of the material receiving bin 4. A plurality of vertically arranged material receiving springs 52 are fixedly connected to the outer bottom wall of the material receiving hopper 51, and one end of each material receiving spring 52 away from the bottom wall of the material receiving hopper 51 is fixedly connected to the inner bottom wall of the opposite material receiving bin 4.

[0047] An opening is provided on one side of the receiving hopper 51 close to the discharge port 41, and a swing door 511 is provided at the opening of the receiving hopper 51. The upper side wall of the swing door 511 is rotatably connected to the adjacent side wall of the receiving hopper 51. The swing door 511 can pass through the discharge port 41 to connect the interior of the receiving hopper 51 with the outside of the receiving bin 4.

[0048] A push plate 53 is also provided inside the receiving hopper 51. The push plate 53 is vertically arranged and slides and abuts against the inner wall of the adjacent receiving hopper 51 in the horizontal direction. The push plate 53 is arranged opposite to the swing door 511. A horizontally arranged push screw 54 is fixedly connected to the side of the push plate 53 away from the swing door 511. The end of the push screw 54 away from the push plate 53 penetrates the side wall of the receiving hopper 51 and the receiving bin 4, and rotates with the side wall of the receiving hopper 51 and the receiving bin 4 in the vertical direction and is slidably connected in the vertical direction.

[0049] The outer part of each push screw 54 is threadedly sleeved with an oil push gear 55, which is located outside the material receiving bin 4 and meshed with a vertically arranged push rack 56. The push rack 56 is fixedly connected to the outer wall of the material receiving bin 4.

[0050] During the processing, the debris gradually falls into the receiving hopper 51. As the amount of debris inside the receiving hopper 51 increases, the receiving hopper 51 gradually moves downward. During the downward movement, the receiving hopper 51 drives the push plate 53, the push screw 54, and the push gear 55 to move downward. During the downward movement, the push gear 55 meshes with the push rack 56 and drives the push gear 55 to rotate. During the rotation, the push gear 55 drives the push screw 54 and the push plate 53 to move, so that the push plate 53 can push the debris inside the receiving hopper 51 out of the receiving bin 4 from the opening on one side of the receiving bin 4, thereby realizing the cleaning process of the processing debris inside the receiving bin 4.

[0051] Reference Figure 1 , Figure 4 and Figure 5 Two horizontally arranged feeding rollers 6 are arranged near the upper pressing plate 12 and the fixed plate 2 in the direction where the strip steel moves to the upper side of the fixed plate 2. The length direction of each feeding roller 6 is arranged perpendicular to the length direction of the strip steel. The two feeding rollers 6 rotate toward the same end and are plugged with the same end block 61. The side walls of the two feeding rollers 6 close to each other can abut against the same strip steel at the same time, and drive the strip steel to the upper side of the fixed plate 2 by rotating in opposite directions.

[0052] The two feed rollers 6 are connected to the same feed assembly 7, which is also connected to the movable plate 1 and drives the two feed rollers 6 to rotate relative to each other during the downward movement of the movable plate 1, so that the two feed rollers 6 can drive the abutted strip steel to move toward the upper side of the fixed plate 2.

[0053] By providing the feeding roller 6 and the feeding assembly 7, it is possible to realize that in the process of the movable plate 1 moving up and down to process the strip steel, the strip steel can be moved by the feeding assembly 7 in cooperation with the feeding roller 6, thereby facilitating the process of the staff moving the strip steel.

[0054] The feeding assembly 7 includes a feeding gear 71 fixedly sleeved to the end of each feeding roller 6 located inside the same end block 61, and the two feeding gears 71 are meshed with each other. The end of the feeding roller 6 located on the upper side is fixedly sleeved with a feeding ratchet 72. A feeding connecting rod 73 is provided on one side of the feeding ratchet 72. The feeding connecting rod 73 is vertically arranged and a plurality of feeding ratchets 74 are fixedly connected to the lower end of the feeding connecting rod 73 near the feeding ratchet 72. The plurality of feeding ratchets 74 are evenly arranged along the length direction of the feeding connecting rod 73. The upper end of the feeding connecting rod 73 is fixedly connected to the movable plate 1.

[0055] During the upward movement of the movable plate 1, the movable plate 1 drives the feeding connecting rod 73 to move upward, and then when the feeding ratchet 74 contacts the feeding ratchet 72, the feeding ratchet 74 engages with the feeding ratchet 72 and continues to move upward with the movable plate 1, so that the feeding connecting rod 73 cooperates with the feeding ratchet 74 to drive the feeding ratchet 72 to rotate. During the rotation process, the feeding ratchet 72 drives the two feeding rollers 6 to rotate relative to each other, thereby driving the strip steel to move toward the upper side of the fixed plate 2 during the upward movement of the movable plate 1, making the strip steel processing process more convenient.

[0056] A locking assembly 8 is provided inside the end block 61 connected to the ends of the two feed rollers 6 away from the push gear 55. The locking assembly 8 is connected to the movable plate 1, and the locking assembly 8 can limit the rotation of the two feed rollers 6 during the downward movement of the movable plate 1.

[0057] By providing the locking assembly 8, the rotation of the feed roller 6 can be restricted by the locking assembly 8 during the downward movement of the movable plate 1, thereby enabling the cutting knife assembly 3 to accurately cut the strip steel.

[0058] The locking assembly 8 includes two locking blocks 81 disposed opposite to each other between the two feed rollers 6, and each locking block 81 can abut against the side walls of the ends of the two feed rollers 6 at the same time. The opposite sides of the two locking blocks 81 are fixedly connected with locking screws 82, and each locking screw 82 is horizontally disposed and rotatably and slidably connected with the end block 61. The outer portion of each locking screw 82 is threadedly sleeved with a locking gear 83, and one side of each locking gear 83 is provided with a locking rack 84, and the lower side of each locking rack 84 is provided with a polished rod, and each locking rack 84 can mesh with the locking gear 83.

[0059] During the downward movement of the moving plate 1, the moving plate 1 drives the locking rack 84 to move downward. After moving a certain distance, the locking rack 84 meshes with the locking gear 83 on one side. As the locking rack 84 continues to move downward, the locking rack 84 can drive the locking gear 83 to rotate. During the rotation process, the locking gear 83 drives the connected locking screw 82 to move. During the movement process, the locking screw 82 drives the locking block 81 to move toward the direction close to the feeding roller 6, so that the locking block 81 can limit the rotation of the feeding roller 6 by contacting with the feeding roller 6.

[0060] The embodiment of the present application also discloses a continuous stamping process with smooth operation.

After the cutting is completed, the cylinder 11 is started to drive the movable plate 1 to move upward. During the upward movement of the movable plate 1, the feeding connecting rod 73 is driven to move and the two feeding rollers 6 are rotated, so that the strip steel continues to move toward the upper side of the fixed plate 2; S2: The cylinder 11 is turned on to drive the moving plate 1 to continue to move downward, so that the cutting knife group 3 cuts multiple round holes in the strip steel, and the cutting knife 31 performs a curling operation on one of the square holes, and at the same time partially cuts the edge of the required part, and then the moving plate 1 moves upward and drives the strip steel to continue to move forward; S3: The cylinder 11 is turned on to drive the moving plate 1 and the cutting knife 31 to move downward. The cutting knife 31 flattens the edge of the strip at the square hole of the curling, punches the hole, and cuts the remaining part of the edge of the part again. Then the moving plate 1 moves upward and drives the strip to continue to move forward. S4: The cylinder 11 is turned on to drive the movable plate 1 and the cutting knife 31 to move downward, and the cutting knife 31 punches a circular hole on the part on the strip steel. Then the movable plate 1 moves upward and drives the strip steel to continue to move forward; S5: The cylinder 11 is turned on to drive the movable plate 1 and the cutting knife 31 to move downward, so that the cut edge of the part on the strip is in contact with the cutting knife 31 on the fixed plate 2, thereby performing a preliminary bending on the edge of the part, and then the movable plate 1 moves upward and drives the strip to continue to move forward; S6: The cylinder 11 is turned on to drive the movable plate 1 and the cutting knife 31 to move downward, so that the cut edge of the part on the strip is in contact with the cutting knife 31 on the fixed plate 2, so that the edge of the part is fully bent, and then the movable plate 1 moves upward and drives the strip to continue to move forward; S7: The cylinder 11 is turned on to drive the movable plate 1 and the cutting knife 31 to move downward, so that the edge of the part on the strip is in contact with the cutting knife 31, thereby fully cutting the edge of the part so that the part falls off the connected strip.
