Description

Technical Field

[0001] This utility model relates to the field of stamping devices, and in particular to a precision stamping device for a nut forming machine. Background Technology

[0002] Nuts are a common type of fastener, widely used in various machines, equipment and related instruments. Nuts are mainly formed by stamping dies through the stamping and extrusion of punches to complete the outer contour and inner hole of the nut.

[0003] Existing nut stamping equipment first extrudes and stamps the outer shape of the nut, then uses a punch to stamp the inner hole of the nut. In the two forming processes, the raw material is first stamped to form a nut blank with a hexagonal cross-section, and then the nut blank is moved to another die for inner hole stamping. The operation is relatively complicated. During the nut moving process, due to the different stamping steps, the outer stamping die and the inner hole stamping die are subjected to different forces, which will produce slight deformations and cause differences in internal size. During the inner hole stamping process, the size of the nut blank will be changed, which will affect the processing accuracy of the nut. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a precision stamping device for a nut forming machine, which aims to improve the problem of needing to change molds when stamping nuts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision stamping device for a nut forming machine, comprising a bracket, a base plate fixedly connected to the inner wall of the bracket, a rotating disk rotatably connected to the inner wall of the base plate, a plurality of stamping dies slidably connected to the inner wall of the rotating disk, a plurality of slide rail blocks slidably connected to the top of the rotating disk, a motor fixedly connected to the bottom of the bracket, a second bevel gear fixedly connected to the output end of the motor, a first bevel gear meshing with the outer wall of the second bevel gear, a dial fixedly connected to the inner wall of the first bevel gear, a grooved wheel slidably connected to the outer wall of the dial, a slide rod fixedly connected to the inner wall of the bracket, a connecting frame slidably connected to the outer wall of the slide rod, a stamping machine fixedly connected to the top of the connecting frame, a first stamping head, a second stamping head, and a third stamping head sequentially fixedly connected to the bottom of the connecting frame, and a fixing component provided at the top of the base plate.

[0012] Preferably, the grooved wheel is fixedly connected to the bottom end of the rotating disk, and the grooved wheel is slidably connected to the bottom end of the base plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the connecting frame is moved downward by the stamping machine, so that the stamping head of the connecting frame stamps the raw material. The motor drives the grooved wheel and the rotating disk to rotate intermittently. At the same time, the stamping die moves the raw material to the next position, so that the stamping machine stamps the raw material again. During the stamping process, the four stamping dies of the rotating disk have the functions of transporting raw material, stamping the outer shape of the raw material, forming the inner hole of the nut, and removing the nut. This ensures that the nut raw material is always stamped in the same die, achieving a more accurate stamping effect.

[0015] 2. In this utility model, the raw material transport rail is placed at the top of the bottom plate below the first stamping head, pushing the raw material to move within the raw material transport rail. A discharge port is provided at the bottom right end of the raw material transport rail, allowing the raw material to fall into the stamping die. Since the tops of the stamping die and the slide block are on the same horizontal plane, the bottom end of the raw material can slide. The bottom plate has two discharge ports, allowing waste materials and nuts to fall into the waste box and the finished product box respectively, thereby reducing manual intervention in the stamping work and preventing injury.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a precision stamping device for a nut forming machine, comprising a support 1, a base plate 3 fixedly connected to the inner wall of the support 1, a rotating disk 4 rotatably connected to the inner wall of the base plate 3, a plurality of stamping dies 5 slidably connected to the inner wall of the rotating disk 4, a plurality of slide rail blocks 6 slidably connected to the top of the rotating disk 4, a motor 17 fixedly connected to the bottom end of the support 1, a second bevel gear 16 fixedly connected to the output end of the motor 17, a first bevel gear 15 meshing with the outer wall of the second bevel gear 16, and a dial 1 fixedly connected to the inner wall of the first bevel gear 15. 4. A grooved wheel 13 is slidably connected to the outer wall of the dial 14. A slide rod 2 is fixedly connected to the inner wall of the bracket 1. A connecting frame 7 is slidably connected to the outer wall of the slide rod 2. A punching machine 12 is fixedly connected to the top of the connecting frame 7. A first punching head 8, a second punching head 9, and a third punching head 10 are fixedly connected to the bottom of the connecting frame 7 in sequence. A fixing component is provided at the top of the base plate 3. The fixing component includes bolts 11. Multiple bolts 11 penetrate the stamping die 5 and are threaded to the inner wall of the rotating disk 4. Multiple bolts 11 penetrate the slide rail block 6 and are threaded to the inner wall of the rotating disk 4.

[0024] Specifically, the stamping machine 12 drives the connecting frame 7 under the guidance of the slide rod 2, so that the first stamping head 8, the second stamping head 9, and the third stamping head 10 simultaneously stamp the stamping die 5 below. The first stamping head 8 performs external stamping on the raw material, the second stamping head 9 performs internal stamping on the raw material that has already been externally stamped, and the third stamping head 10 is used to prevent the nut stuck in the inner wall of the stamping die 5 from interfering with the stamping equipment, thereby impacting and causing the nut to fall off. The motor 17 at the bottom of the bracket 1 drives the second bevel gear 16, which causes the first bevel gear 15 and the dial 14 to rotate, thereby driving the grooved wheel 13 and the rotating disk 4 to rotate intermittently, so that the stamping die 5 in the rotating disk 4 moves the raw material, achieving the effect that the raw material is always stamped in the original die.

[0025] Reference Figure 1 and Figure 2 A waste box 18 is fixedly connected to the inner wall of the bracket 1, and a finished product box 19 is fixedly connected to the inner wall of the bracket 1.

[0026] Specifically, by placing a waste box 18 on the inner wall of the support 1 below the second stamping head 9, and by placing a finished product box 19 on the inner wall of the support 1 below the third stamping head 10, the effect of collecting waste parts and finished products can be achieved.

[0027] Reference Figure 1 and Figure 3 The top of the base plate 3 is provided with a raw material transport rail 20, and the stamping die 5 is slidably connected to the outer wall of the slide rail block 6.

[0028] Specifically, by placing a raw material transport rail 20 on the top of the base plate 3 above the front stamping die 5, the raw material in the raw material transport rail 20 can fall into the stamping die 5. The stamping die 5 and the slide block 6 are in contact, and their tops are on the same horizontal plane. When the rotating disk 4 rotates, the bottom of the raw material can slide on the top of the stamping die 5 and the slide block 6, so as to achieve the effect of the raw material automatically falling into the stamping die 5.

[0029] Reference Figure 1 and Figure 2 The stamping machine 12 is fixedly connected to the inner wall of the bracket 1, and the stamping die 5 is slidably connected to the inner wall of the base plate 3.

[0030] Specifically, the stamping machine 12 is fixed to the inner wall of the bracket 1 to prevent the stamping head from being affected by vibration during the stamping process. The bottom end of the stamping die 5 slides on the inner wall of the base plate 3 to prevent the bottom end of the raw material from having errors after being stamped.

[0031] Reference Figure 2 The first stamping head 8 is slidably connected to the inner wall of the stamping die 5, the second stamping head 9 is slidably connected to the inner wall of the stamping die 5, and the second stamping head 9 is slidably connected to the inner wall of the base plate 3.

[0032] Specifically, the outer wall of the first stamping head 8 slides on the inner wall of the stamping die 5 to ensure the accuracy of the material when it is stamped in the shape. The outer wall of the second stamping head 9 slides on the inner wall of the stamping die 5 and the base plate 3 to ensure the accuracy of the material when it is stamped in the inner hole, thereby achieving the effect of processing the stamping material with high precision.

[0033] Reference Figure 2 The dial 14 is rotatably connected to the inner wall of the bracket 1 and to the bottom end of the base plate 3.

[0034] Specifically, the dial 14 is rotatably connected between the bottom end of the base plate 3 and the bottom end of the bracket 1, so that the dial 14 will not wobble when it rotates, thus ensuring the stable rotation of the dial 14.

[0035] Reference Figure 2 and Figure 4 The grooved wheel 13 is fixedly connected to the bottom end of the rotating disk 4, and the grooved wheel 13 is slidably connected to the bottom end of the base plate 3.

[0036] Specifically, the top of the grooved wheel 13 is fixedly connected to the bottom of the rotating disk 4, so that the base plate 3 is clamped in it, thereby ensuring that the dial 14 can rotate stably when it drives the rotating disk 4 to rotate.

[0037] Working principle: Multiple raw materials are placed in the raw material transport rail 20. The raw materials are pushed so that the material at the right end falls into the stamping die 5 below. Then, the drive motor 17 drives the second bevel gear 16 and the first bevel gear 15 to rotate, causing the dial 14 to rotate, which in turn drives the grooved wheel 13 to rotate. This causes the rotating disk 4 to drive the stamping die 5 to rotate, so that the raw materials below the raw material transport rail 20 are moved to another position and then fall into the stamping die 5 below the raw material transport rail 20. The drive press 12 drives the connecting frame 7 and about a few stamping heads to punch downwards. The first raw material is pressed to form its outer shape. After the rotating disc 4 moves the material to the next position, it falls back into the stamping die 5 from the material transport rail 20. The stamping machine 12 then stamps the material again, allowing the first material to form its inner hole and the second material to form its outer shape. The rotating disc 4 then rotates again, causing the first material to fall into the finished product box 19, and the material from the material transport rail 20 falls back into the stamping die 5. This process of rotating the die causes the materials inside to rotate together, thus automating the stamping process and eliminating the need for manual operation. This equipment not only eliminates the need to move the material and change dies for stamping but also reduces manual labor.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
