Description
Technical Field
[0001] This utility model relates to the field of machining technology, and more specifically, to a stamping die for porous thin-walled products. Background Technology
[0002] Thin-walled products refer to parts or products with relatively thin walls. In manufacturing (especially injection molding, casting, stamping, and other fields), thin-walled products refer to a class of parts or finished products whose wall thickness is much smaller than other structural dimensions (such as length, width, height, or diameter). Currently, punching is a common operation in the production and manufacturing of thin-walled products. However, existing punching dies are inconvenient for positioning and flattening during the punching process, which can easily affect the accuracy and quality of punching. At the same time, the continuity of punching for longer thin-walled products is relatively poor. Therefore, it is necessary to propose a stamping die for porous thin-walled products to solve the above problems. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a stamping die for porous thin-walled products, aiming to improve the problems of existing punching dies, such as the inconvenience of positioning and flattening during the stamping process, which easily affects the accuracy and quality of punching, and the relatively poor continuity of stamping for longer thin-walled products.
[0004] This utility model is implemented as follows: This utility model provides a stamping die for porous thin-walled products, including a support structure and a stamping structure.
[0005] The supporting structure includes a stamping table, a top plate, and a lower punch. The stamping table has a through hole inside, and a fixing rod is fixed between the stamping table and the top plate. The lower punch is installed on the top surface of the stamping table, and punches are spaced apart inside the lower punch. Grooves are formed on both sides of the lower punch. The stamping structure includes a stamping cylinder, a limiting member, a support frame, and a driving member. The stamping cylinder is installed on the top surface of the top plate, and an upper punch is installed at the output end of the stamping cylinder. Punches are spaced apart on the upper punch. The limiting member is installed between the stamping table and the top plate. The support frame is installed on one side of the stamping table, and an extrusion member is installed on the support frame. The driving member is installed between the extrusion member and the support frame.
[0006] In one embodiment of this utility model, the bottom of the stamping table is symmetrically fixed with support columns, the bottom of the support columns is fixed with support plates, and the interior of the support plates is provided with nail holes in a circumferential manner.
[0007] In one embodiment of this utility model, the limiting member includes four limiting rods, a first fixing frame, and a first support roller. The four limiting rods are symmetrically fixed between the stamping table and the top plate. A spring is sleeved on each limiting rod. The first fixing frame is slidably sleeved on the limiting rod. The two ends of the spring are respectively fixed to the first fixing frame and the top plate. A first extrusion roller is rotatably mounted on the first fixing frame. The first support roller is rotatably mounted on the groove.
[0008] In one embodiment of this utility model, the upper end of the punch is formed with an external thread, a limit plate is fixed on the punch, and a threaded hole matching the external thread is provided on the upper punch seat.
[0009] In one embodiment of this utility model, the extrusion component includes a movable frame, a threaded sleeve, and a second support roller. The movable frame is slidably connected to the support frame, and the second extrusion roller is installed on the movable frame. The threaded sleeve is fixed to the support frame, and a threaded rod is threadedly connected to the threaded sleeve. The threaded rod rotatably passes through the support frame, and a rotating handle is keyed to the end of the threaded rod. The second support roller is rotatably installed on the support frame.
[0010] In one embodiment of this utility model, the support frame is provided with a sliding groove, and the movable frame has notches on both sides that match the sliding groove, and the notches are slidably connected to the sliding groove.
[0011] In one embodiment of the present invention, the second extrusion roller is located above the second support roller, and the first extrusion roller is located above the first support roller.
[0012] In one embodiment of this utility model, the driving component includes a stepper motor and a first gear. The stepper motor is mounted on the support frame, and a second gear is keyed to the end of the output shaft of the stepper motor. The first gear is keyed to one end of the second support roller, and the first gear meshes with the second gear.
[0013] The beneficial effects of this utility model are as follows: This utility model provides a stamping die for porous thin-walled products. During use, the thin-walled material is passed between the first extrusion roller and the first support roller. The elasticity of the spring allows the material to be flatly fixed on the surface of the lower punch. Then, the material passes between the second extrusion roller and the second support roller. By rotating the handle, the threaded rod is turned, causing the threaded sleeve to move the second extrusion roller downwards, clamping the material between them. A stepper motor drives the second gear to rotate intermittently, which in turn drives the first gear and the second support roller to rotate. Simultaneously, the stamping cylinder operates, causing the upper punch and punch to move downwards to engage the corresponding punch holes, completing the stamping operation on the thin-walled material. This facilitates the extrusion, positioning, and flattening of the thin-walled material during the stamping process, improving stamping stability, accuracy, and quality. It also enhances stamping continuity, increases stamping efficiency, and makes the product more convenient to use. Attached Figure Description

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Example Please see Figures 1-4 This utility model provides a technical solution: a stamping die for porous thin-walled products, including a support structure 100 and a stamping structure 200.
[0019] Please see Figures 1-3 The support structure 100 includes a stamping table 110, a top plate 140, and a lower punch 150. The stamping table 110 has a through hole 111 inside. A fixing rod 130 is fixed between the stamping table 110 and the top plate 140. The lower punch 150 is installed on the top surface of the stamping table 110. The lower punch 150 has punch holes 151 spaced apart inside. The lower punch 150 has grooves 152 on both sides. Here, the punch holes 151 are located above the through holes 111.
[0020] The bottom of the stamping table 110 is symmetrically fixed with support columns 120, and the bottom of the support columns 120 is fixed with a support plate 121. The support plate 121 has circumferential nail holes inside, which facilitates installation and fixing.
[0021] Please see Figures 1-4The stamping structure 200 includes a stamping cylinder 210, a limiting member 230, a support frame 240, and a driving member 260. The stamping cylinder 210 is installed on the top surface of the top plate 140. An upper punch seat 220 is installed at the output end of the stamping cylinder 210. Punches 221 are installed at intervals on the upper punch seat 220. The limiting member 230 is installed between the stamping table 110 and the top plate 140. The support frame 240 is installed on one side of the stamping table 110. An extrusion member 250 is installed on the support frame 240. The driving member 260 is installed between the extrusion member 250 and the support frame 240.
[0022] The limiting component 230 includes four limiting rods 231, a first fixing frame 233, and a first support roller 235. The four limiting rods 231 are symmetrically fixed between the stamping table 110 and the top plate 140. A spring 232 is sleeved on the limiting rod 231. The first fixing frame 233 is slidably sleeved on the limiting rod 231. The two ends of the spring 232 are fixed to the first fixing frame 233 and the top plate 140, respectively. A first extrusion roller 234 is rotatably mounted on the first fixing frame 233. The first support roller 235 is rotatably mounted on the groove 152. Here, the elasticity of the spring 232 can make the first extrusion roller 234 tightly adhere to the first support roller 235. Here, the extrusion of the limiting components 230 on both sides of the lower punch 150 can extrude and flatten thin-walled products, thereby improving the stamping accuracy and stamping quality.
[0023] The upper end of the punch 221 has an external thread, and a limit plate is fixed on the punch 221. The upper punch seat 220 has a threaded hole that matches the external thread. The external thread and the threaded hole make it easy to disassemble and assemble the punch 221, so that the distance between punches can be adjusted during punching, making it more flexible and convenient to use. The extrusion component 250 includes a movable frame 251, a threaded sleeve 253, and a second support roller 256. The movable frame 251 is slidably connected to the support frame 240. The second extrusion roller 252 is mounted on the movable frame 251. The threaded sleeve 253 is fixed to the support frame 240. A threaded rod 254 is threadedly connected to the threaded sleeve 253. The threaded rod 254 rotatably passes through the support frame 240. A bearing is interference-fitted onto the threaded rod 254 and embedded in the support frame 240, which facilitates the rotation of the threaded rod 254. A rotating handle 255 is keyed to the end of the threaded rod 254. The second support roller 256 is rotatably mounted on the support frame 240. By rotating the threaded rod 254, the threaded sleeve 253 drives the second extrusion roller 252 to move downward. This facilitates the extrusion and fixing of thin-walled products of different thicknesses, thereby facilitating driving movement. The support frame 240 has a slide groove 241, and the movable frame 251 has notches 2511 on both sides that match the slide groove 241. The notches 2511 are slidably connected to the slide groove 241. The setting of the slide groove 241 and the notches 2511 can improve the stability of the movable frame 251 in raising and lowering.
[0024] The second extrusion roller 252 is located above the second support roller 256, and the first extrusion roller 234 is located above the first support roller 235. The drive unit 260 includes a stepper motor 261 and a first gear 262. The stepper motor 261 is mounted on the support frame 240, and the end of the output shaft of the stepper motor 261 is keyed to the second gear 263. The first gear 262 is keyed to one end of the second support roller 256, and the first gear 262 meshes with the second gear 263. By utilizing the intermittent operation of the stepper motor 261, the second gear 263 can be driven to rotate, which in turn drives the first gear 262 and the second support roller 256 to rotate. In this way, the raw material for thin-walled products can be continuously moved outward, thereby improving the continuity of stamping and increasing efficiency.
[0025] Specifically, the working principle of this stamping die for porous thin-walled products is as follows: During use, the thin-walled material is passed between the first extrusion roller 234 and the first support roller 235. The elasticity of the spring 232 allows the material to be flatly fixed on the surface of the lower punch 150. Then, the material passes between the second extrusion roller 252 and the second support roller 256. Finally, by rotating the handle 255, the threaded rod 254 is rotated, causing the threaded sleeve 253 to move the second extrusion roller 252 downwards, clamping the thin-walled material between the second extrusion roller 252 and the second support roller 256. During this process, the stepper motor 261 drives the second gear 263 to rotate intermittently. The second gear 263 drives the first gear 262 and the second support roller 256 to rotate. At the same time, the stamping cylinder 210 works to drive the upper punch seat 220 and the punch head 221 to move downward to cooperate with the corresponding punch hole 151, thus completing the stamping operation of the thin-walled material. In this way, the thin-walled material can be easily squeezed, positioned and flattened during the stamping process, which is beneficial to improving the stability, accuracy and quality of stamping. At the same time, it can also improve the continuity of stamping, improve stamping efficiency and make it more convenient to use.
[0026] It should be noted that the specific model and specifications of the stamping cylinder 210 and the stepper motor 261 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0027] The power supply and operating principle of the stamping cylinder 210 and the stepper motor 261 are clear to those skilled in the art and will not be described in detail here.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
