Description

Technical Field

[0001] This utility model relates to the field of screw heading machine technology, specifically to a multi-station screw heading machine. Background Technology

[0002] The heading machine belongs to the cold heading equipment. Its function is to punch one die and two punches to produce products. It is mainly used for forming the head of screw products. Its working principle is to straighten the wire, feed the wire, cut it, feed it into the main die, perform the first punch for initial forging, and then punch the formed blank to exit. The work is completed in one go, and the production capacity can reach about 200 pieces per minute. It is a relatively advanced product in terms of current technology.

[0003] Heading machines can manufacture common products such as self-tapping screws, electrical screws, miniature screws, internal and external hex bolts, self-drilling screws, and fiberboard screws. If a male mold ejection device is added, it can also upset other non-standard and special-shaped hardware products. However, existing heading machines often have only one station. During the heading process, the screws need to be picked up, placed, and headed sequentially at a single station, resulting in low heading efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a multi-station screw heading machine to solve the technical problem of low heading efficiency caused by the need for screw heading machines to perform sequential picking, placing and heading operations at a single station.

[0005] According to one aspect, at least one embodiment of the present invention provides a multi-station screw heading machine, including a base, a support frame, a stamping seat, a support column, a limiting mechanism, a grooved wheel mechanism, and a pushing mechanism. A U-shaped support frame is fixedly mounted on the base. Two stamping seats are fixedly mounted on the top side wall of the base. The support column is rotatably mounted on the inner top wall of the support frame. Two stamping heads are symmetrically arranged around the periphery of the support column. The limiting mechanism is mounted on the support column to limit the stamping heads. The grooved wheel mechanism is mounted on the support frame to drive the support column to rotate intermittently. The pushing mechanism is mounted on the support frame to push the stamping heads to head the screws.

[0006] Preferably, the limiting mechanism includes a limiting plate, a limiting ring, a limiting ring, a limiting post, and a limiting component. Four limiting plates are fixedly arranged at equal angles on the side wall of the support post. The limiting ring is fixedly arranged at the end of the limiting plate away from the support post. The limiting ring is arranged on the periphery of the support post and is fixedly connected to the limiting ring. Two opposing limiting posts are slidably arranged in the axial direction. The limiting posts are fixedly connected to the stamping head. The limiting component is arranged between the limiting posts and the limiting ring to limit the position between the limiting posts and the limiting ring.

[0007] Furthermore, the limiting component includes a positioning ring and a support spring. The positioning ring is fixedly provided at both ends of the side wall of the limiting post. The support spring is sleeved on the limiting post, and both ends of the support spring are in contact with the limiting ring and the positioning ring at the top of the position, respectively.

[0008] Furthermore, the Geneva mechanism includes a fixed cover, a Geneva body, an active dial, and a first motor. The fixed cover is fixedly mounted on the top side wall of the support frame, the Geneva body is rotatably mounted on the top side wall of the support frame, a connecting rod is fixedly mounted between the Geneva body and the support column, the active dial, which cooperates with the Geneva body, is rotatably mounted on the inner top wall of the fixed cover, and the first motor is mounted on the top side wall of the fixed cover, with its output end fixedly connected to the active dial.

[0009] Furthermore, the pushing mechanism includes a push plate and a hydraulic rod. The push plate is slidably disposed within the support frame, and a push block is fixedly disposed on the top side wall of the push plate. The hydraulic rod is mounted on the support frame, and the output end of the hydraulic rod is fixedly connected to the push block.

[0010] Based on the above scheme, a first mounting ring is fixedly provided on the side wall of the stamping head, and a plurality of first bolts are provided through the first mounting ring and the limiting post.

[0011] Based on the above scheme, a second mounting ring is fixedly provided on the side wall of the stamping seat, and a plurality of second bolts are provided through the second mounting ring and the base.

[0012] Based on the above scheme, the first motor is a servo motor.

[0013] The beneficial effects of the embodiments of this utility model are as follows:

[0014] 1. In this utility model, by setting two stamping seats and two stamping heads, the stamping heads can be moved sequentially to the top side of the two stamping seats for heading operation by the operation of the limiting mechanism and the groove wheel mechanism. While one stamping seat is heading, the screw can be picked up and repositioned on the other stamping seat, thereby improving the heading efficiency.

[0015] 2. In this utility model, by setting up the grooved wheel mechanism, the operation of the first motor can drive the active dial to rotate, and then through the cooperation of the active dial and the grooved wheel body, the grooved wheel body and the support column are driven to rotate intermittently, so that the stamping head can be moved to the top of the stamping seat in sequence for the heading operation through the limit plate and the limit ring.

[0016] 3. In this utility model, by setting up a pushing mechanism, after the stamping head moves above the stamping seat, the working of the hydraulic rod can drive the push block and push plate to move, thereby facilitating the stamping head to drive the limit post to be driven by the push plate to be pressed by the limit post to be driven to be headed by the stamping head.

[0030] like Figures 1-5As shown, this invention illustrates a multi-station screw heading machine according to one embodiment of the present invention. It includes a base 1, a support frame 2, a stamping seat 3, a support column 4, a limiting mechanism, a grooved wheel mechanism, and a pushing mechanism. A U-shaped support frame 2 is fixedly mounted on the base 1. Two stamping seats 3 are fixedly mounted on the top side wall of the base 1. A support column 4 is rotatably mounted on the inner top wall of the support frame 2. Two stamping heads 5 are symmetrically arranged around the periphery of the support column 4. The limiting mechanism is mounted on the support column 4 to limit the stamping heads 5. The grooved wheel mechanism is mounted on the support frame 2 to drive the support column 4 to rotate intermittently. The pushing mechanism is mounted on the support frame 2 to push the stamping heads 5 to head the screws. A first mounting ring 19 is fixedly mounted on the side wall of the stamping head 5. Multiple first bolts pass through the first mounting ring 19 and the limiting column 9. A second mounting ring 20 is fixedly mounted on the side wall of the stamping seat 3. Multiple second bolts pass through the second mounting ring 20 and the base 1.

[0031] Reference Figures 1-4 The limiting mechanism includes a limiting plate 6, a limiting ring 7, a limiting ring 8, a limiting post 9, and a limiting assembly. Four limiting plates 6 are fixedly installed at equal angles on the side wall of the support post 4. The limiting ring 7 is fixedly installed at the end of the limiting plate 6 away from the support post 4. The limiting ring 8 is installed on the periphery of the support post 4 and is fixedly connected to the limiting ring 7. Two opposing limiting posts 9 are slidably installed along the axial direction and are fixedly connected to the stamping head 5. The limiting assembly is installed between the limiting posts 9 and the limiting ring 7 to limit the position between the limiting posts 9 and the limiting ring 7. The limiting component includes a positioning ring 10 and a support spring 11. Positioning rings 10 are fixedly installed at both ends of the side wall of the limiting post 9. The support spring 11 is fitted on the limiting post 9. The two ends of the support spring 11 contact the limiting ring 7 and the positioning ring 10 at the top of the position, respectively. Specifically, the operation of the grooved wheel mechanism can drive the limiting ring 7 to move sequentially above the two stamping seats 3 and perform the heading operation. While one stamping seat 3 is being headed, the screw can be removed and repositioned on the other stamping seat 3, thereby improving the heading efficiency.

[0032] Reference Figure 5The Geneva mechanism includes a fixed cover 12, a Geneva body 13, an active dial 14, and a first motor 15. The fixed cover 12 is fixedly mounted on the top side wall of the support frame 2. The Geneva body 13 is rotatably mounted on the top side wall of the support frame 2. A connecting rod is fixedly mounted between the Geneva body 13 and the support column 4. The active dial 14, which cooperates with the Geneva body 13, is rotatably mounted on the inner top wall of the fixed cover 12. The first motor 15 is mounted on the top side wall of the fixed cover 12. The output end of the first motor 15 is fixedly connected to the active dial 14. The first motor 15 is a servo motor. Specifically, the operation of the first motor 15 can drive the active dial 14 to rotate. Then, through the cooperation of the active dial 14 and the Geneva body 13, the Geneva body 13 and the support column 4 are driven to rotate intermittently. Thus, the stamping head 5 can be moved sequentially above the stamping seat 3 for heading operation through the limit plate 6 and the limit ring 7.

[0033] Reference Figure 1 and Figure 2 The pushing mechanism includes a push plate 16 and a hydraulic rod 18. The push plate 16 is slidably disposed in the support frame 2. A push block 17 is fixedly disposed on the top side wall of the push plate 16. The hydraulic rod 18 is mounted on the support frame 2. The output end of the hydraulic rod 18 is fixedly connected to the push block 17. Specifically, after the stamping head 5 moves above the stamping seat 3, the operation of the hydraulic rod 18 can drive the push block 17 and the push plate 16 to move, thereby facilitating the stamping head 5 to drive the limit post 9 to be headed by the extrusion of the push plate 16.

[0034] In this embodiment, during use, the operator places the screw on the stamping seat 3, and then controls the first motor 15 to work. The operation of the first motor 15 can drive the active dial 14 to rotate, and then through the cooperation of the active dial 14 and the grooved wheel body 13, the grooved wheel body 13 and the support column 4 are driven to rotate intermittently. Thus, the limit plate 6 and the limit ring 7 can move the stamping head 5 to move sequentially above the stamping seat 3. After the stamping head 5 moves above the stamping seat 3, the operation of the hydraulic rod 18 can drive the push block 17 and the push plate 16 to move, so that the push plate 16 can squeeze the limit column 9 to drive the stamping head 5 to head the screw. While one stamping seat 3 is heading, the screw can be picked up and repositioned in the other stamping seat 3, thereby improving the heading efficiency.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
