Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a one-time stamping mold for automotive parts. Background Technology

[0002] Stamping of automotive parts is a process that uses molds and stamping equipment to apply pressure to metal sheets to plastically deform them, thereby efficiently and accurately manufacturing complex-shaped parts such as body panels and structural parts. It has the advantages of high material utilization and low cost, and is widely used in the production of parts such as car doors, hoods, and crossbeams.

[0003] In existing technologies, when stamping metal materials using stamping dies, metal scraps are usually separated and fall off. These scraps are of different sizes and shapes and are usually collected together, which is not conducive to recycling. To address this issue, a one-time stamping die for automotive parts is proposed. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A one-time stamping die for automotive parts includes a recycling mechanism, and a stamping mechanism is provided above the recycling mechanism. The stamping mechanism includes a hydraulic cylinder.

[0006] The recycling mechanism includes a lower mold base, and a receiving chamber is provided in the middle of the inner wall of the lower mold base. A guide block is movably installed inside the receiving chamber. The top surface of the guide block is sloped, and a number of positioning grooves are also provided on the top surface of the guide block. Each positioning groove is equidistant along the length direction of the top surface of the guide block.

[0007] The guide block is provided with threaded holes on its side and near the lower end of each positioning groove.

[0008] The positioning slot has a positioning block that is slidably installed inside it. The top of the positioning block extends above the positioning slot and is fixedly connected to a limiting frame. The bottom surface of the limiting frame also abuts against the top surface of the guide block.

[0009] As a further embodiment of this utility model: the lower end of the outer wall of the limiting frame is provided with a mounting hole, the mounting hole and the threaded hole are aligned with each other, and a bolt passes through the mounting hole and is threadedly fastened to the limiting frame.

[0010] As a further embodiment of this utility model: the lower end of the limiting frame is provided with mounting holes 2 on both sides, and the lower end of the limiting frame is also movably installed with scrap material box 1 and scrap material box 2. The mounting holes 2 are threaded with through bolts and are threadedly fastened to both scrap material box 1 and scrap material box 2.

[0011] As a further embodiment of this utility model: a lower mold is fixedly installed on the top of the lower mold base, and a discharge hole is opened on the surface of the lower mold, the discharge hole being connected in communication with the receiving chamber.

[0012] As a further embodiment of this utility model: the stamping mechanism includes a top plate, and support rods are fixedly connected to all four sides of the bottom surface of the top plate, and a hydraulic cylinder is fixedly installed at the center of the top surface of the top plate.

[0013] As a further embodiment of this utility model: the extension end of the hydraulic cylinder faces downward and is fixedly connected to an upper mold base, and an upper mold is fixedly installed in the middle of the bottom surface of the upper mold base, with the upper mold located directly above the discharge hole.

[0014] As a further embodiment of this utility model: through holes are provided around the surface of the upper mold base, and each through hole is slidably connected to a different support rod.

[0015] The beneficial effects of this utility model are:

[0016] (1) The present invention provides a guide block inside the lower die base. The scrap generated after stamping of automotive parts falls to the top of the guide block through the discharge hole. As a result, the metal scrap is subjected to gravity and falls into the prepared scrap box one or scrap box two along the slope of the top surface of the guide block, which facilitates the rapid collection of metal scrap.

[0017] (2) A limiting frame is installed on the top of the guide block. The limiting frame limits the movement direction of the metal scrap and prevents the metal scrap from deviating when it slides down. This ensures that metal scraps of different shapes or sizes fall into different scrap boxes, so as to achieve classified collection and convenient reuse. In addition, the spacing between the limiting frames can be adjusted to facilitate matching with lower molds of different sizes or shapes. Attached Figure Description

[0027] like Figure 1-6 As shown, a one-time stamping die for automotive parts includes a recycling mechanism 1, a stamping mechanism 2 above the recycling mechanism 1, and a hydraulic cylinder 203. The recycling mechanism 1 includes a lower die base 101, with a receiving chamber 104 in the middle of the inner wall of the lower die base 101. A guide block 105 is movably installed inside the receiving chamber 104. The top surface of the guide block 105 has a slope, and several positioning grooves 106 are also provided on the top surface of the guide block 105. Each positioning groove 106 is equidistantly arranged along the length of the top surface of the guide block 105. Threaded holes 107 are also provided on the side of the guide block 105 and near the lower end of each positioning groove 106. A positioning block 109 is slidably installed inside the positioning groove 106. The top of the positioning block 109 extends above the positioning groove 106 and is fixedly connected to a limit frame 108. The bottom surface of the limit frame 108 abuts against the top surface of the guide block 105. Figure 4 As shown, the limiting frame 108 divides the space on the top surface of the guide block 105, thereby separating and guiding metal scraps of different shapes or sizes.

[0028] The lower end of the outer wall of the limit bracket 108 is also provided with a mounting hole 110, which is aligned with the threaded hole 107. A bolt passes through the mounting hole 110 and is threadedly fastened to the limit bracket 108. Mounting holes 111 are also provided on both sides of the lower end of the limit bracket 108. Scrap material boxes 112 and 113 are movably mounted on the lower end of the limit bracket 108. Bolts pass through the mounting holes 111 and are threadedly fastened to both scrap material boxes 112 and 113. Figure 4 As shown, the scrap bins in the device can be set to different specifications, and can be used with limit frames 108 of different spacings to collect scraps. The instruction manual only shows two sizes of scrap bins.

[0029] A lower mold 102 is fixedly mounted on the top of the lower mold base 101. A discharge hole 103 is provided on the surface of the lower mold 102, and the discharge hole 103 is internally connected to the receiving chamber 104. Figure 2 As shown, the lower mold 102 is fixed inside the lower mold base 101 by fasteners. The lower mold 102 can be disassembled and replaced, and the spacing and number of the top limit brackets 108 of the guide block 105 must be adjusted synchronously.

[0030] The stamping mechanism 2 includes a top plate 201. Support rods 202 are fixedly connected to all four sides of the bottom surface of the top plate 201. A hydraulic cylinder 203 is fixedly installed at the center of the top surface of the top plate 201. The extension end of the hydraulic cylinder 203 faces downwards and is fixedly connected to an upper die base 204. An upper die 206 is fixedly installed at the center of the bottom surface of the upper die base 204. The upper die 206 is located directly above the discharge hole 103. Through holes 205 are opened around all four sides of the surface of the upper die base 204, and each through hole 205 is slidably connected to a different support rod 202. Figure 3 As shown, the upper mold 206 is also fixed to the bottom of the upper mold base 204 by fasteners. The upper mold 206 needs to be replaced and installed in conjunction with the lower mold 102.

[0031] The working principle of this utility model:

[0032] When the device is in use, the metal sheet is placed inside the lower mold 102. When the hydraulic cylinder 203 is started, the extension end drives the upper mold base 204 to fall. The upper mold 206 squeezes the metal sheet, and the cut metal scraps are squeezed and pushed into the discharge hole 103. Then they fall to the top of the guide block 105. Under the action of gravity, the metal scraps fall along the slope of the top surface of the guide block 105 into the scrap box 112 or the scrap box 213.

[0033] Secondly, in order to guide metal scraps of different shapes and sizes, and according to the different quantities of scraps produced in a single stamping, positioning blocks 109 can be inserted into positioning slots 106. Then, different numbers or different spacing of limit frames 108 are installed on the top of the guide block 105. When fixing the guide block 105 and the limit frame 108, the bolts are passed through the mounting hole 110 and tightened inside the threaded hole 107. In addition, when disassembling the scrap box 112 or the scrap box 213 and taking out the collected metal scraps, the bolts connected to the mounting hole 211 can be removed.

[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
