Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to a punching guide device for server shell punching. Background Technology

[0002] As a platform that carries and protects the precision electronic components inside the server, the server casing requires extremely high manufacturing precision. It is usually made of thin metal sheets through punching, bending and other processes.

[0003] In traditional stamping production, punch presses use their powerful impact force to quickly form sheet metal. However, when processing high-precision and thin-material workpieces such as server casings, the shortcomings of existing technology gradually become apparent. First, even if the operator performs preliminary positioning of the sheet metal before stamping, the dynamic offset generated during processing is difficult to control, directly leading to deviations in hole positions or inaccurate bending angles in the final product, which seriously affects the assembly accuracy and overall quality of the server chassis.

[0004] The instantaneous impact force generated when a punch press presses down is a huge challenge for thin-walled sheet metal. In order to achieve shearing or plastic deformation of the metal, the impact force must be large enough. However, for thin sheet metal with limited ductility, this overly concentrated and violent impact force often exceeds its bearing limit, easily causing stress concentration at the edge of the stamping area, which can lead to permanent deformation, warping, or even micro-cracks in the material. This not only damages the structural integrity of the workpiece but also greatly reduces the product qualification rate. Existing stamping equipment often focuses on providing sufficient stamping force but lacks an effective buffering and softening mechanism for this force, making it difficult to balance processing efficiency with the protection of thin sheet materials.

[0005] Therefore, this utility model proposes a stamping guide device for server shell punching to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems in the existing technology of server shell punching guide device, such as the server shell and other thin plates are misaligned during punching due to unstable positioning, resulting in reduced hole and bending accuracy, and the instantaneous impact force during punching is too strong, which easily causes deformation and cracking of thin plates and low yield. The present invention aims to provide a server shell punching guide device with improved structure that can effectively solve the above problems.

[0007] This utility model provides a stamping guide device for a server shell punching press used in a stamping machine, comprising: a guide stamping machine; and a material plate fixing mechanism and a buffer mechanism disposed within the guide stamping machine. The material plate fixing mechanism includes a drive motor, a gear transmission mechanism, a threaded rod, and a moving block; the buffer mechanism includes a stamping base plate, a moving plate, a pressure spring, and a buffer spring.

[0008] Furthermore, the drive motor is connected to the gear transmission mechanism, which drives the threaded rod to rotate. The threaded rod engages with the moving block to drive the moving block to produce linear motion. The stamping base plate is driven by the stamping machine. The pressure spring is set between the stamping base plate and the moving plate, and the buffer spring supports the moving plate. When the stamping base plate is pressed, it can drive the moving plate to move, thereby compressing the pressure spring and the buffer spring in sequence.

[0009] Preferably, the gear transmission mechanism includes a first bevel gear connected to the output end of the drive motor, and a second bevel gear meshing with the first bevel gear, the second bevel gear being coaxially fixed on the threaded rod.

[0010] Preferably, the material plate fixing mechanism further includes a support plate, with the threaded rod and the moving block housed within the support plate. The support plate is used to guide the linear movement of the moving block.

[0011] Preferably, the outer wall of the moving block is provided with a protruding block, and the inner wall of the support plate is provided with a limiting structure that slides with the protruding block to prevent the moving block from falling off the support plate.

[0012] Preferably, the material plate fixing mechanism further includes a drive rod, which is used to drive a gear transmission mechanism located on both sides of the material plate to achieve synchronous movement.

[0013] Preferably, the material plate fixing mechanism further includes a fixing block, and the drive rod is rotatably inserted through the fixing block.

[0014] Preferably, the buffer mechanism further includes a central column, and a moving plate is sleeved on the outer periphery of the central column and can slide along its axial direction.

[0022] Beneficial effects:

[0023] 1. This utility model, by setting up a material plate fixing mechanism composed of a drive motor, gear transmission mechanism, threaded rod and moving block, synchronously and stably clamps and fixes both sides of the material plate before stamping, solves the problem in the prior art that thin plates such as server shells will shift during stamping due to insecure positioning, resulting in a decrease in hole position and bending accuracy. It achieves the technical effect of accurately fixing the server shell material plate, effectively avoiding shifting during stamping, and thus significantly ensuring the accuracy of hole position and bending.

[0024] 2. This utility model, by setting a two-stage buffer mechanism consisting of a stamping base plate, a moving plate, a pressing spring, and a buffer spring, transforms the instantaneous impact force during stamping into a flexible force. This solves the problem in the prior art where the impact force during the pressing of the punch press is too strong, which easily leads to deformation, cracking, or even tearing of thin plates and low yield. It achieves the technical effect of effectively buffering the instantaneous impact force when stamping the material plate, thereby avoiding deformation and cracking of thin plates due to excessive force and improving the product qualification rate.

[0025] 3. This utility model organically combines the material plate fixing mechanism that achieves precise positioning with the buffering mechanism that achieves impact buffering, so that they work together to solve the comprehensive problem that existing stamping devices cannot simultaneously take into account both positioning accuracy and material protection when processing thin-walled parts. It achieves the technical effect of ensuring both processing accuracy and protecting the integrity of materials, making the overall structure of the device reasonable and the functions comprehensive, and it is particularly suitable for processing high-precision thin-walled parts. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a stamping guide device for server shell punching, which aims to solve the problems of inaccurate positioning and easy deviation during the stamping of thin plates such as server shells, and the easy deformation and cracking of plates caused by instantaneous impact force in the prior art.

[0029] like Figure 1 and Figure 2 As shown, the server shell punching press guiding device is used in the punching machine 4. It includes a guiding punching machine 1, and a material plate fixing mechanism 2 and a buffer mechanism 3 are provided in the guiding punching machine 1. The material plate fixing mechanism 2 is used to clamp and fix the material plate before punching, and the buffer mechanism 3 is used to buffer the impact force generated when the punching machine 4 presses down.

[0030] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structure of the material plate fixing mechanism 2. Please refer to the following for details. Figure 2 and Figure 3 The structure will be described in detail below:

[0031] The material plate fixing mechanism 2 includes a drive motor 201, a support plate 207, a gear transmission mechanism, a threaded rod 205, and a moving block 206. The gear transmission mechanism is connected to the drive motor 201 and is used to drive the threaded rod 205 to rotate. The threaded rod 205 is threadedly engaged with the moving block 206. The support plate 207 is used to guide and limit the movement of the moving block 206. The gear transmission mechanism includes a first bevel gear 203 fixedly connected to the output end of the drive motor 201, and a second bevel gear 204 meshing with the first bevel gear 203. The second bevel gear 204 is coaxially fixed on the threaded rod 205. The threaded rod 205 and the moving block 206 are both accommodated in the support plate 207. Inside 07, a protruding block is provided on the outer wall of the moving block 206, and a limiting structure that slides with the protruding block is provided on the inner wall of the support plate 207 to prevent the moving block 206 from falling off the support plate 207. In order to achieve synchronous clamping of both sides of the material plate, the material plate fixing mechanism 2 also includes a drive rod 202 and a fixing block 208. The drive rod 202 is rotatably inserted in the fixing block 208. The drive rod 202 is used to drive and synchronously drive two sets of gear transmission mechanisms located on both sides of the material plate. This transmission structure, which drives the gears by the motor, the screws by the gears, and the slider by the screws, ensures that the material plate can be clamped and fixed stably, accurately and synchronously.

[0032] Based on the above embodiments, the buffer mechanism 3 will be further described in detail. Please refer to [link / reference]. Figure 4 The buffer mechanism 3 includes a central column 306, a moving plate 304 sleeved on the outer periphery of the central column 306 and capable of sliding along its axial direction, a limit cover 302 fixed on the top of the central column 306, a stamping base plate 301 disposed above the moving plate 304, a pressure spring 303 disposed between the stamping base plate 301 and the moving plate 304, a buffer spring 305 supported below the moving plate 304, and the limit cover 302 used to limit the reset position of the stamping base plate 301. This structure, which guides the moving plate 304 through the central column 306 and limits the stamping base plate 301 through the limit cover 302, ensures the motion stability of the buffer mechanism 3 during operation and reset.

[0033] Working principle: After the material sheet slides into the guide stamping machine 1, the drive motor 201 in the material plate fixing mechanism 2 is activated. The drive motor 201 drives the bevel gear 203 fixedly connected to its output end. As the bevel gear 203 rotates inside the support plate 207, it drives the drive rod 202 rotating inside the fixed block 208. This causes the bevel gear 203 fixed to the other end of the drive rod 202 to rotate synchronously. Subsequently, multiple bevel gears 203 mesh with bevel gears 204 and rotate together. As the bevel gear 204 rotates, it drives the threaded rod 205 fixed at its top. During the rotation of the threaded rod 205, the moving block 206 rises steadily under the limiting guidance of the support plate 207. After the moving block 206 rises to a certain height, the outer wall protrusion block is stuck inside the support plate 207 to prevent it from falling off. As the moving block 206 of the material plate fixing mechanism 2 is stuck on both sides of the material plate, the server shell material plate is precisely fixed, avoiding displacement during stamping and ensuring the accuracy of hole positions and bending.

[0034] When the stamping machine 4 of the guide stamping press 1 is started, the material plate is pressed down. At this time, the stamping base plate 301 in the buffer mechanism 3 is pressed down. When the stamping base plate 301 is pressed down, the stamping base plate 301 disengages from the limiting cover 302 near the edge and the pressing spring 303 is pressed down. When the pressing spring 303 is subjected to downward pressure, it will move the moving plate 304 down together. Then the buffer spring 305 retracts. After the pressing is finished, the buffer spring 305 releases and lifts the moving plate 304. During the upward movement of the moving plate 304 on the outer wall of the central column 306, the pressing spring 303 lifts the stamping base plate 301, so that the stamping base plate 301 returns to its position at the bottom of the limiting cover 302 at the top of the central column 306. This achieves the buffering of the instantaneous impact force when stamping the material plate, thereby avoiding the deformation and cracking of the thin plate due to excessive force.
