Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a side-positioned limiting stamping die. Background Technology

[0002] In modern manufacturing, stamping has become one of the core processes in the field of metal plastic forming due to its significant advantages such as high efficiency, low cost and mass production capability. It is widely used in many key industries such as automobiles, electronics, home appliances, and aerospace. As the core equipment for realizing this process, the performance of stamping dies directly determines the precision, quality, production efficiency and manufacturing cost of stamped parts.

[0003] When existing stamping dies are in operation, the die is mainly placed in a worktable. The worktable provides stable support and positioning reference to ensure that the die remains stable during the stamping process.

[0004] However, in the actual stamping process, when the cylinder presses down and generates huge pressure on the die, the powerful impact force at the moment of contact can easily cause the die to shift momentarily or wobble slightly. Even if the magnitude of this shift is small, it may disrupt the original precise positioning of the blank. This is especially true for stamping parts with extremely high dimensional accuracy requirements, which can directly lead to quality problems such as dimensional deviations and shape deformations in the workpiece. This not only affects the production continuity of the stamping die but also reduces work efficiency. Utility Model Content

[0005] This invention effectively resists the impact of impact forces by using a clamping and limiting component, preventing momentary positional shifts or slight wobbling of the mold. This ensures that the mold maintains its original precise positioning, thereby reducing downtime for adjustment caused by mold shifts. This not only guarantees the continuity of stamping mold production but also improves overall work efficiency, thus solving the problems mentioned in the background art.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: Refer to Figure 1 - Figure 3As shown: A side-positioned limiting stamping die includes multiple sets of support columns 1;

[0028] Clamping and limiting component 2 is set on top of multiple sets of support columns 1;

[0029] The buffer stamping assembly 3 is disposed on top of the clamping and limiting assembly 2;

[0030] The clamping and limiting assembly 2 includes a mounting plate 201, multiple sets of baffles 208, and a fixing plate 213. A servo motor 202 is fixedly mounted near the center of the bottom of the mounting plate 201. The output end of the servo motor 202 slides through the bottom of the mounting plate 201 and extends to one side. A swing plate 203 is fixedly connected to the output end of the servo motor 202. Two sets of connecting posts 204 are symmetrically fixedly connected to the top of the swing plate 203. Pulling plates 205 are rotatably connected to the outer surfaces of the two sets of connecting posts 204. Fixing posts 206 are rotatably connected to the inner walls of the two sets of pulling plates 205. Moving plates 207 are fixedly connected to the bottom of the two sets of fixing posts 206. A set of limiting posts 209 are fixedly connected to the inner walls of the multiple sets of baffles 208. Two sets of moving plates 207 are fixedly connected to the inner walls of the baffles 208. The inner wall of the 7 is slidably connected to the outer surface of the limiting post 209. The top of each of the two sets of moving plates 207 is fixedly connected to a sliding block 210. The outer surface of each of the two sets of sliding blocks 210 is fixedly connected to a limiting block 211. The outer surface of each of the two sets of limiting blocks 211 is bonded with a silicone pad 212. The top of the fixed plate 213 is symmetrically provided with two sets of sliding grooves 214. The top of the fixed plate 213 is fixedly installed with a worktable 215 near the center. The inner wall of the two sets of sliding grooves 214 is slidably connected to the outer surface of the sliding block 210. The bottom of the mounting plate 201 is fixedly connected to the top of the multiple sets of support posts 1. The bottom of the multiple sets of baffles 208 is fixedly connected to the top of the mounting plate 201. The top of the multiple sets of baffles 208 is fixedly connected to the bottom of the fixed plate 213.

[0031] In this embodiment, when performing stamping operations using this side-positioned limiting stamping die device, the operator must first accurately place the die to be stamped on the worktable 215 of the equipment, ensuring that the bottom of the die is in stable contact with the surface of the worktable 215. After the initial placement of the die is completed, the servo motor 202 at the bottom of the mounting plate 201 is started. Its output end drives the swing plate 203 connected to it to rotate. The rotation amplitude and frequency of the swing plate 203 are controlled by the servo motor 202. During the continuous swinging of the swing plate 203, the connecting columns 204 at both ends are pulled synchronously. At this time, the movement of the connecting columns 204 drives the pulling plate 205. Driven by 205, the fixed column 206 will undergo horizontal displacement. The movement of the fixed column 206 will directly drive the movable plate 207 fixed to it, causing the two sets of movable plates 207 to move towards each other along the direction closer to the mold. When the movable plate 207 moves, the limiting column 209 installed between the baffles 208 will limit the movement direction of the movable plate 207, effectively preventing the movable plate 207 from shifting laterally or shaking during the force process, ensuring that it always moves smoothly along a straight line. At the same time, the sliding block 210 will slide synchronously along the sliding groove 214 opened on the fixed plate 213, further strengthening the guiding and limiting effect on the movable plate 207. As the plates 207 continue to move closer, the limiting blocks 211 on opposite sides of the two sets of moving plates 207 will also gradually approach the mold. A layer of uniformly thick silicone pads 212 is adhered to the surface of each limiting block 211. When the limiting block 211 contacts the edge of the mold, the silicone pads 212 will first undergo slight deformation, utilizing their elastic properties to absorb the impact force generated during clamping. This prevents rigid collisions between the limiting blocks 211 and the mold from causing scratches, dents, or other damage to the mold surface, while also ensuring tight clamping. When the two sets of limiting blocks 211 are fully fitted to the mold and reach the preset clamping force, the servo motor 202 will automatically stop operating. At this point, the mold is firmly fixed in place. On the workbench 215, with all positional parameters meeting the stamping requirements, the operator can start the main drive system of the stamping equipment after confirming that the mold is fixed correctly. The upper mold moves downward under the drive mechanism and begins to perform the stamping process on the blank in the mold. Under the action of the clamping and limiting component 2, it can effectively resist the impact of the impact force and avoid the mold from momentary positional displacement or slight shaking, so that the mold can always maintain its original precise positioning state, thereby reducing the downtime adjustment time caused by mold displacement. This not only ensures the continuity of stamping mold production, but also improves the overall work efficiency. The support column 1 is mainly used to support and fix the entire device.

[0032] Example 2: According to Figure 1 - Figure 5As shown: The buffer stamping assembly 3 includes a bracket 301. An electric cylinder 302 is fixedly installed at the top of the bracket 301 near the center. The telescopic end of the electric cylinder 302 slides through the top of the bracket 301 and extends downward. A connecting plate 303 is fixedly installed at the telescopic end of the electric cylinder 302. Multiple sets of dampers 304 are arranged and fixedly installed at the bottom of the connecting plate 303. Each set of dampers 304 is provided with a buffer spring 305. A pressure plate 306 is fixedly installed at one end of each set of dampers 304. The bottom of the bracket 301 is fixedly connected to the top of the fixed plate 213.

[0033] In this embodiment, after the clamping and limiting component 2 is used to limit and fix the mold, the electric cylinder 302 installed above the bracket 301 is activated. After the electric cylinder 302 is activated, its telescopic end will extend downward in the vertical direction, thereby driving the connecting plate 303 connected to it to press downward synchronously. During the downward movement of the connecting plate 303, the pressure plate 306 installed at its bottom will first contact the surface of the workpiece in the mold. At this time, the buffer spring 305 set between the connecting plate 303 and the pressure plate 306 will undergo elastic deformation due to compression. At the same time, the damper 304 will also play a damping role. The two together form a double buffer structure. Under the action of the buffer stamping component 3, the instantaneous impact force generated on the workpiece when the pressure plate 306 presses down can be effectively relieved, avoiding damage to the surface of the workpiece or deformation of the internal structure due to excessive pressure, and ensuring that the workpiece remains stable in the initial pressure stage.

[0034] Working principle: First, the mold is placed on the worktable 215 of the equipment. The servo motor 202 is started to drive the swing plate 203 to rotate. During the swing of the swing plate 203, the connecting column 204 is pulled synchronously. At this time, the movement of the connecting column 204 drives the pulling plate 205. Under the drive of the pulling plate 205, the fixed column 206 will be displaced. The movement of the fixed column 206 will directly drive the moving plate 207, making the moving plate 207 move closer. When the moving plate 207 moves, the limiting column 209 will limit the movement direction of the moving plate 207. At the same time, the sliding block 210 will slide synchronously along the sliding groove 214 opened on the fixed plate 213, further strengthening the guiding and limiting effect on the moving plate 207. As the moving plate 207 continues to move closer, the limiting block 211 will also gradually move closer to the mold. When the limiting block 210... When the silicone pad 212 comes into contact with the edge of the mold, it will first undergo slight deformation to prevent the rigid collision between the limiting block 211 and the mold from causing scratches, dents and other damage to the mold surface. When the limiting block 211 is fully attached to the mold and reaches the preset clamping force, the servo motor 202 will automatically stop running. At this time, the mold is firmly limited and fixed on the worktable 215. Then, the electric cylinder 302 is started, and its telescopic end will extend downward in the vertical direction. Then the connecting plate 303 presses down synchronously. During the downward movement of the connecting plate 303, the pressure plate 306 will first come into contact with the surface of the workpiece in the mold. The buffer spring 305 will undergo elastic deformation due to compression. At the same time, the damper 304 will also play a damping role. The two together form a double buffer structure to effectively reduce the instantaneous impact force on the workpiece when the pressure plate 306 presses down.

[0035] By following the steps outlined above, you can complete the use of the side-positioned limiting stamping die.
