Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-6 In this embodiment of the present invention, a precision control structure for a stamping machine includes an operating table 100. Support legs 110 are fixedly connected to the four corners of the bottom surface of the operating table 100. A lower die base 111 is fixedly connected to the center of the top surface of the operating table 100. Two feeding conveyor belts 112 and two unloading conveyor belts 113 are symmetrically arranged on the top surface of the operating table 100. The two feeding conveyor belts 112 are located to the right of the lower die base 111, and the two unloading conveyor belts 113 are located to the left of the lower die base 111. Two rectangular slots 114 are symmetrically formed on the top surface of the operating table 100 with the lower die base 111 as the center. A lead screw 130 is rotatably connected inside each of the two rectangular slots 114. A clamping assembly 140 is screwed onto the outer wall of the lead screw 130 on the left side, and a clamping assembly 150 is screwed onto the outer wall of the lead screw 130 on the right side. Side plates 115 are fixedly connected to the top surface of the operating table 100 near the edges on both sides. An L-shaped frame 120 is fixedly connected to the side wall of the operating table 100. A hydraulic cylinder 121 is fixedly connected to the top surface of the L-shaped frame 120. An upper mold base 122 is installed through the top surface of the L-shaped frame 120. The upper mold base 122 is located directly above the lower mold base 111. Motors 131 are fixedly connected to the interior of the operating table 100 near both ends. The motor shafts of the two motors 131 are respectively connected to one end of the two lead screws 130.

[0040] Specifically, the worker places the material to be stamped onto the feeding conveyor belt 112. The side plates 115 at the edge of the feeding conveyor belt 112 ensure that the material will not slip or shift during the conveying process. The feeding conveyor belt 112 conveys the material forward at a constant speed until the front end of the material approaches the edge of the lower die holder 111. When the material is conveyed to the position above the lower die holder 111, the motors 131 located on both sides of the lower die holder 111 are started, causing the two lead screws 130 to rotate. This causes the clamping assembly 140 and the clamping assembly 150 to move towards each other, clamping the material and pressing it completely onto the lower die holder 111, ensuring the stable position of the material during the stamping process. After positioning, the hydraulic cylinder 121 is activated to begin the stamping operation. The upper die holder 122 descends to cooperate with the lower die holder 111 to complete the stamping operation. During the stamping process, clamping component one 140 and clamping component two 150 remain stationary to ensure the stability and accuracy of the material during the stamping process. After the stamping is completed, clamping component one 140 and clamping component two 150 are controlled to move away from the material and no longer clamp it. Clamping component two 150 is then controlled to push the stamped material. Under the action of the thrust, the material comes into contact with the activated unloading conveyor belt 113 and is then conveyed away, completing the entire unloading process. After the above steps are completed, the loading stage is restarted to prepare for the next stamping operation, forming a cyclical operation process. Example 1

[0041] like Figures 2-3 As shown, in this embodiment, a connecting rod 1121 is fixedly connected between the drive rollers on the two feeding conveyor belts 112, and a connecting rod 2131 is fixedly connected between the drive rollers on the two unloading conveyor belts 113. A motor 1122 and a motor 2132 are fixedly connected to the outer wall of one of the side plates 115. The motor shaft of the motor 1122 is connected to the drive roller of one of the feeding conveyor belts 112, and the motor shaft of the motor 2132 is connected to the drive roller of one of the unloading conveyor belts 113.

[0042] In this embodiment, the sides of the two upper die holders 122 and the two unloading conveyor belts 113 are close to the inner walls of the two side plates 115. Since the drive rollers of the two upper die holders 112 are connected by connecting rod 1121 and the drive rollers of the two unloading conveyor belts 113 are connected by connecting rod 1131, starting motor 1122 or motor 1132 can make the two upper die holders 112 or the two unloading conveyor belts 113 drive synchronously. When feeding is required, the stamping material is placed on the surface of the two upper die holders 112, that is, between the two side plates 115. Starting motor 1122 causes the two upper die holders 112 to transport the stamping material to the lower die holder 111. After stamping is completed, starting motor 1132 causes the two unloading conveyor belts 113 to transport the stamped material away. This eliminates the need for workers to directly contact the stamping area and reduces operational risks.

[0043] like Figures 3-6 As shown, in this embodiment, clamping assembly 140 includes a movable base 141, the outer wall of which is slidably connected to the inner wall of the rectangular groove 114. A threaded hole 1 is provided through the side wall of the movable base 141, and the threaded hole 1 is screwed into the outer wall of the corresponding lead screw 130. Two electric telescopic rods 142 are installed and fixed inside the movable base 141. Each of the two electric telescopic rods 142 extending out of the top surface of the movable base 141 has a fixed block 143. A clamping plate 144 is fixedly connected to the side wall of the two fixed blocks 143 near the lower mold base 111. Clamping assembly 150 includes a movable base 151, the outer wall of which is slidably connected to the inner wall of the rectangular groove 114. The inner wall of the rectangular groove 114 is slidably connected. The side wall of the movable seat 151 is provided with a threaded hole 2. The threaded hole 2 is screwed to the outer wall of the corresponding lead screw 130. Two electric telescopic rods 152 are installed and fixed inside the movable seat 151. The output ends of the two electric telescopic rods 152 extending out of the top surface of the movable seat 151 are fixedly connected to a connecting plate 153. Two electric telescopic rods 154 are installed and fixed inside the connecting plate 153. The output ends of the two electric telescopic rods 154 extending from the side of the connecting plate 153 near the lower mold base 111 are fixedly connected to a clamping plate 155. Rubber pads are adhered to the opposite side walls of the clamping plate 144 and the clamping plate 155.

[0044] In practice, when the stamping material is conveyed on the feeding conveyor belt 112, the electric telescopic rod one 142 and the electric telescopic rod two 152 retract, causing the top surfaces of the clamping plates one 144 and two 155 to be lower than the surfaces of the lower die base 111, the feeding conveyor belt 112, and the unloading conveyor belt 113. Simultaneously, two motors three 131 are activated, causing the two lead screws 130 to rotate, thus causing the clamping components one 140 and two 150 to move in opposite directions. When the front end of the material approaches the edge of the lower die base 111, that is, when it is located between the clamping components one 140 and two 150, the two motors three 131 can be activated again, and the electric telescopic rod one 142 retracts. 142 and the second electric telescopic rod 152 extend, causing the first clamping assembly 140 and the second clamping assembly 150 to move towards each other, thereby smoothly pushing the material onto the surface of the lower die base 111. The material is then clamped and fixed by the first clamping plate 144 and the second clamping plate 155. The hydraulic cylinder 121 is activated to lower the upper die base 122 to perform a stamping operation on the material. After the stamping is completed, the first electric telescopic rod 142 is first controlled to retract, causing the first clamping plate 144 to descend. Then, the two third electric telescopic rods 154 are controlled to extend, causing the second clamping plate 155 to push the material onto the lower material conveyor belt 113. The second motor 1132 is then activated, causing the lower material conveyor belt 113 to transport the material away. Example 2

[0045] like Figures 1-3As shown, in this embodiment, a waste bin 116 is provided below the operating table 100 at a position corresponding to the lower mold base 111. The opening on the top surface of the waste bin 116 corresponds to the hole on the lower mold base 111. A drawer slot is provided on the side wall of the waste bin 116, and a collection box 117 is slidably inserted into the drawer slot.

[0046] In practice, during the stamping process, the lower die holder 111 and the upper die holder 122 work together to press and shear the material to form the required workpiece shape. At the same time, the scrap material that is stamped off will fall smoothly along the scrap hole on the lower die holder 111 under the action of the stamping force, and thus fall into the scrap box 116 and be collected by the collection box 117, thereby realizing the separation of scrap material from workpiece. The collection box 117 can be pulled out for unified processing of scrap material.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
