Description

Technical Field

[0001] This utility model belongs to the technical field of metal processing equipment and related accessories, and in particular relates to a fixing structure for a metal stamping die. Background Technology

[0002] Metalworking is a process technology that transforms metal materials into items, parts, and components. It includes large parts such as bridges and ships, as well as small components such as engines, jewelry, and watches. It is widely used in various fields such as science, industry, art, and handicrafts. Among them, hardware parts are various metal devices made of metals such as iron, steel, and aluminum through physical processing such as forging, rolling, and cutting. In the stamping process of hardware parts, they generally need to be placed in a suitable stamping die for stamping. In order to ensure the quality of stamping, the stamping die needs to be fixed to prevent displacement during the operation.

[0003] A search revealed that publication number CN218341879U, with an application date of August 24, 2022, discloses a fixing structure for a precision stamping die, including a main support frame and a hydraulic telescopic rod. A placement table is fixedly installed above the main support frame, and an equipment support assembly is provided at the front end of the placement table. The equipment support assembly includes a connecting plate, a sliding groove, a slider, and a placement frame. A sliding groove is provided on the inner side of the connecting plate, and a slider is slidably connected to the inner side of the sliding groove. The hydraulic telescopic rod is fixedly installed above the placement table.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The existing fixing structure of hardware stamping dies uses two sets of hydraulic telescopic rods to push the fixing plate to clamp the stamping die during use. However, this method only clamps and limits the stamping die in two directions, which will affect the stability of the stamping die under high load conditions.

[0006] 2. Existing fixing structures for metal stamping dies use two sets of hydraulic telescopic rods to clamp the die, but this method requires multiple sets of equipment, increasing operating costs. Therefore, we provide a fixing structure for metal stamping dies to solve the aforementioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a fixing structure for a metal stamping die. By setting a transmission component, the upper and lower double-threaded rods can rotate independently, allowing the left and right clamping plates and the front and rear clamping plates to be adjusted individually according to the size of the metal stamping die. This provides a wide range of applications and clamping and fixing in multiple directions, resulting in better stability. Furthermore, by utilizing an adjustment component, the electromagnetic block generates a magnetic attraction with the iron block after being energized, thereby adjusting the position of the L-shaped hanging plate, motor, worm gear, etc., to achieve individual adjustment of the rotation of the upper or lower double-threaded rod, reducing equipment operating costs.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a fixed structure for a hardware stamping die, including a processing table and movable holes opened at both ends of the upper surface. A transmission component is provided at the bottom of the processing table, and an adjustment component is provided on one side of the bottom of the processing table.

[0010] The transmission assembly includes an upper double-threaded rod suspended directly below the processing table, and a lower double-threaded rod located directly below the upper double-threaded rod;

[0013] The present invention is further configured such that a driven gear disc is sleeved on the outer wall of both the upper and lower double-threaded rods, and a movable seat is screwed onto both ends of the outer wall of both the upper and lower double-threaded rods.

[0014] The present invention is further configured such that the threads on the outer walls of the upper double-threaded rod and the lower double-threaded rod are helically engaged with the internal threads in the wall of the threaded hole on the movable seat, and the movable seat is slidably installed inside the movable hole.

[0015] The present invention is further configured such that a clamping plate is bolted to one end of the top of the movable seat, and anti-slip protrusions are evenly spaced on the inner wall of the clamping plate. Both ends of the upper double threaded rod and the lower double threaded rod are rotatably mounted in bearings on the inner wall of the side plate.

[0016] The present invention is further configured such that a partition is fixed on the inner wall of the L-shaped hanging plate, a top plate is fixed on the top of the L-shaped hanging plate, and the output shaft of the motor is connected to the worm gear through a coupling.

[0017] The present invention is further configured such that the top end of the worm gear is rotatably connected to the bearing on the partition plate and the bearing on the inner wall of the top plate, and a slider is fixedly provided at one end of the top of the top plate.

[0018] The present invention is further configured such that an iron block is embedded inside the slider, and the iron block and the electromagnetic block are attracted by magnetic force, and the slider is slidably installed inside the slide groove.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a transmission component, allows the upper and lower double-threaded rods to rotate independently, enabling the left and right clamping plates and the front and rear clamping plates to be individually adjusted according to the size of the metal stamping die. It has a wide range of applications and provides clamping and fixing in multiple directions, resulting in better stability. This solves the problem that the existing fixing structure of metal stamping dies uses two sets of hydraulic telescopic rods to push the fixing plate to clamp the stamping die during use. However, this method only clamps and limits the stamping die in two directions, which affects the stability of the stamping die under high load conditions.

[0021] 2. This utility model, by setting an adjustment component, generates a magnetic attraction between the electromagnetic block and the iron block after the electromagnetic block is energized, and adjusts the position of the L-shaped hanging plate, motor, worm gear, etc., to realize the individual adjustment of the rotation of the upper double threaded rod or the lower double threaded rod, reducing the equipment operating cost. It also solves the problem that the existing hardware stamping die fixing structure requires two sets of hydraulic telescopic rods to clamp the stamping die, which requires multiple sets of equipment and thus increases the equipment operating cost.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] Please see Figures 1 to 4 This utility model is a fixing structure for a hardware stamping die, including a processing table 100 and movable holes 101 opened at both ends of the upper surface. A transmission assembly 200 is provided at the bottom of the processing table 100. The transmission assembly 200 includes an upper double threaded rod 201 suspended directly below the processing table 100 and a lower double threaded rod 202 located directly below the upper double threaded rod 201.

[0033] Specifically, a slide groove 102 is provided on one side of the bottom of the processing table 100, and electromagnetic blocks 102a are embedded in the inner walls of both sides of the slide groove 102; driven gear disks 201a are sleeved on the outer walls of the upper double threaded rod 201 and the lower double threaded rod 202, and movable seats 203 are screwed onto both ends of the outer walls of the upper double threaded rod 201 and the lower double threaded rod 202; the threads on the outer walls of the upper double threaded rod 201 and the lower double threaded rod 202 are screwed into the internal threads in the threaded hole wall of the movable seat 203, and the movable seat 203 is slidably installed inside the movable hole 101; a clamping plate 204 is bolted to one end of the top of the movable seat 203, and anti-slip protrusions 204a are evenly spaced on the inner wall of the clamping plate 204; both ends of the upper double threaded rod 201 and the lower double threaded rod 202 are rotatably installed in bearings on the inner wall of the side plate 205.

[0034] Furthermore, both ends of the outer walls of the upper double-threaded rod 201 and the lower double-threaded rod 202 are provided with forward threads and reverse threads, and the forward threads and reverse threads are helically engaged with the internal threads in the threaded hole wall of the moving seat 203. Therefore, when the upper double-threaded rod 201 and the lower double-threaded rod 202 rotate, they will drive the two sets of moving seats 203 on the outer wall to move in opposite directions. Two sets of electromagnetic blocks 102a are provided, and the anti-slip protrusions 204a further improve the clamping stability of the stamping die.

[0035] The operation process of this embodiment is as follows: When it is necessary to clamp and fix the metal stamping die, the motor 302 is started. The output shaft of the motor 302 rotates, driving the worm gear 302a to rotate through the coupling. The helical teeth on the outer wall of the worm gear 302a mesh with the helical teeth on the outer wall of the upper double threaded rod 201 or the lower double threaded rod 202. Therefore, when the worm gear 302a rotates, it will drive the upper double threaded rod 201 or the lower double threaded rod 202 to rotate. The upper double threaded rod 201 or the lower double threaded rod 202 engages with the internal thread in the threaded hole wall of the upper moving seat 203 on the outer wall. Both ends of the outer wall of the double-threaded rod 201 or the lower double-threaded rod 202 are provided with forward and reverse threads. Therefore, when the upper double-threaded rod 201 or the lower double-threaded rod 202 rotates, it will drive the moving seats 203 at both ends of the outer wall to move in opposite directions. This causes the clamping plates 204 on the oppositely arranged moving seats 203 to move in opposite directions, which can clamp onto the outer wall of the metal stamping die and fix it. At the same time, the left and right clamping plates 204 and the front and rear clamping plates 204 can be adjusted individually according to the size of the metal stamping die, making it widely applicable.

[0036] Example 2

[0037] Please see Figure 2 and Figure 5 Based on Embodiment 1, unlike the first embodiment, an adjustment component 300 is provided. The adjustment component 300 includes an L-shaped hanging plate 301 set below the processing table 100 and a motor 302 installed at the bottom of the L-shaped hanging plate 301. This solves the problem that the existing hardware stamping die fixing structure uses two sets of hydraulic telescopic rods to clamp the stamping die during use, which requires multiple sets of equipment and thus increases the equipment usage cost.

[0038] Specifically, a partition 301a is fixed on the inner wall of the L-shaped hanging plate 301, and a top plate 301b is fixed on the top of the L-shaped hanging plate 301. The output shaft of the motor 302 is connected to the worm gear 302a through a coupling. The top end of the worm gear 302a passes through the bearing on the partition 301a and is rotatably connected to the bearing on the inner wall of the top plate 301b. A slider 303 is fixed at one end of the top of the top plate 301b. An iron block 303a is embedded inside the slider 303. The iron block 303a and the electromagnetic block 102a are attracted by magnetic force. The slider 303 is slidably installed inside the slide groove 102.

[0039] Furthermore, the helical teeth on the outer wall of the worm gear 302a mesh with the helical teeth on the outer wall of the driven gear disk 201a, which plays a role in transmission. When one of the electromagnetic blocks 102a is energized, it generates a magnetic attraction with the iron block 303a, causing the slider 303 to move along the direction of the magnetic force.

[0040] The operation process of this embodiment is as follows: When it is necessary to drive either the upper double threaded rod 201 or the lower double threaded rod 202 to rotate, the electromagnetic block 102a near the side of the upper double threaded rod 201 or the lower double threaded rod 202 is energized. After the electromagnetic block 102a is energized, it will generate a magnetic attraction to the iron block 303a, causing the slider 303 to move along the inside of the slide groove 102, and driving the top plate 301b, L-shaped hanging plate 301, motor 302, worm gear 302a, etc. to move. The worm gear 302a continuously approaches the upper double threaded rod 201 or the lower double threaded rod 202, so that the helical teeth on the outer wall of the worm gear 302a contact and mesh with the helical teeth on the outer wall of the upper double threaded rod 201 or the lower double threaded rod 202. Then, the upper double threaded rod 201 or the lower double threaded rod 202 can be driven to rotate by the motor 302. This allows for quick adjustment of the rotation of the upper double threaded rod 201 or the lower double threaded rod 202 and reduces the equipment operating cost.
