Description

A head-wrapping device for processing T-bolts Technical Field

[0001] This utility model applies to the field of T-bolt production technology, and particularly relates to a head-wrapping device for processing T-bolts. Background Technology

[0002] Currently, T-bolts are named for their head shape resembling the letter "T". The horizontal part is used to insert into the slot or hole, and the vertical part is threaded to be fastened with a nut. They are commonly used in furniture, construction and other fields. They are easy to install and have good anti-rotation effect. When manufacturing T-bolts, the head forming process mainly adopts hot forging and stamping technology. The round steel is processed into the required shape through heating and stamping steps, and then subjected to heat treatment and other subsequent processes to improve the material properties.

[0003] However, currently, when stamping the head of a bolt, the bolt is placed on a fixture and then stamped from the top using a stamping mechanism. During this process, to fix the bolt, the operator needs to adjust one side of the fixture for different bolt diameters. This method not only fails to center the bolt but also requires resetting and readjusting the fixture before the bolt can be moved after processing. This overall process is time-consuming and labor-intensive, impacting the efficiency of subsequent head stamping. Therefore, we propose a head-stamping device for T-bolt processing. Summary of the Invention

[0004] The main objective of this invention is to provide a head-wrapping device for processing T-bolts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A head-wrapping device for processing T-bolts includes a processing machine table, a support frame fixedly installed at the top center of the processing machine table, a hydraulic push cylinder vertically fixedly installed at the top center of the support frame, and a lifting plate fixedly installed at the bottom of the piston rod of the hydraulic push cylinder;

[0007] A placement frame is fixedly installed at the top center of the processing machine table. Limiting rollers are movably installed on both sides inside the placement frame. A hollow frame is fixedly installed on the top inner side of the processing machine table. A centering drive mechanism is provided inside the hollow frame, and the centering drive mechanism is connected to the limit roller drive.

[0008] The bottom of the lifting plate is equipped with a pushing mechanism.

[0009] As an optional solution to the technical solution of this application, the centering drive mechanism includes a bidirectional lead screw. Both sides of the bidirectional lead screw are threadedly connected to transmission sleeves. A connecting frame is fixedly installed on the top of the outer side of each transmission sleeve. The vertical cross-section of the connecting frame is T-shaped. The hollow frame and the top of the processing table are provided with sliding grooves, and the connecting frame is slidably inserted into the sliding groove. A fixing frame is vertically fixedly installed on the top surface of each connecting frame. Mounting plates are slidably installed on both ends of the inner side of the placement frame. Connecting plates are fixedly installed on both ends of the side of each mounting plate. An I-shaped rod is rotatably installed between the sides of every two sets of connecting plates through a bearing. A limiting roller is fixedly sleeved on the middle surface of the outer side of the I-shaped rod. A servo motor is fixedly installed on the inner side of the hollow frame, and the side of the servo motor drive shaft is fixedly connected to the top of the side of the bidirectional lead screw through a coupling.

[0010] By adopting the above technical solution, under the rotational transmission action of the transmission sleeve by the bidirectional screw and the connection transmission action of the connecting frame and the fixed frame, the clamping distance between the two sets of limiting rollers is adjusted, while ensuring that the two sets of limiting rollers can move synchronously from both sides of the bolt to be processed. This ensures that the limiting rollers can center and clamp T-bolts of different diameters, thereby ensuring that the hydraulic push cylinder only needs to move vertically to stamp and shape the top of the T-bolt, thus improving the efficiency of the stamping process for the top of the bolt.

[0011] As an optional solution to the technical solution of this application, the pushing mechanism includes a movable plate and a return spring. A movable plate is movably fitted onto the bottom surface of each of the lifting plates. An adsorption magnet is fixedly embedded in the middle of the bottom of the lifting plate. A movable groove is opened in the middle of the movable plate, and the adsorption magnet is movably installed inside the movable groove.

[0012] By adopting the above technical solution, after the top of the stamped bolt is attracted and fixed by the adsorption magnet, the stamped bolt can be moved vertically synchronously with the recovery movement of the hydraulic push cylinder, so that it can be automatically removed from the inside of the placement frame, making it convenient to change the bolt.

[0013] As an optional solution to the technical solution of this application, movable rods are vertically fixedly installed on the four corner surfaces of the top of the movable plate, and the movable rods are slidably inserted into the inside of the side of the lifting plate. A return spring is movably sleeved on the outer surface of each movable rod, and the bottom of the return spring is movably attached to the outer wall of the top of the lifting plate.

[0014] By adopting the above technical solution, the movable rod is pushed back and reset by the return spring, so that after the movable rod moves vertically due to the pushing action of the inner wall of the support frame, the position of the movable rod and the movable plate can be restored, thus ensuring the reusability of the overall mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present application discloses a head-wrapping device for processing T-bolts. This device comprises horizontally movable limiting rollers on both sides of a placement frame and a rotatable bidirectional lead screw on the inside of the processing machine. The bidirectional lead screw, through its rotational transmission action on the transmission sleeves on both sides, drives two sets of transmission sleeves to move synchronously horizontally towards or relative to each other. After the transmission sleeves and movable plate are connected by a connecting frame and a fixed frame, the limiting rollers move horizontally within the placement frame synchronously with the horizontal movement of the transmission sleeves. This allows for adjustment of the clamping distance between the two sets of limiting rollers, ensuring that both sets can move synchronously from both sides of the bolt to be processed. This ensures that the limiting rollers can center and clamp T-bolts of different diameters, thereby allowing the hydraulic push cylinder to perform stamping and shaping of the T-bolt head simply by moving vertically, thus improving the efficiency of head-wrapping stamping processing.

[0017] 2. A head-wrapping device for processing T-bolts according to the technical solution of this application, by setting an adsorption magnet inside the lifting plate and setting movable rods through the inside of the lifting plate on both sides of the top of the movable plate, allows the hydraulic push cylinder to drive the movable plate and the adsorption magnet to descend synchronously to stamp and shape the top of the bolt. Under the adsorption of the adsorption magnet, the shaped bolt can be fixed and adsorbed. As the hydraulic push cylinder moves vertically, it automatically moves out from the surface of the limiting roller. After the movable rod moves synchronously to the inner wall of the support frame, the movable rod is pushed and separated by the abutment action of the inner wall of the support frame, so that the movable plate can descend vertically synchronously to push and separate the bolt adsorbed on the surface of the adsorption magnet. This facilitates the operator to transfer and change the shaped bolt, and further improves the efficiency of head-wrapping stamping processing of the bolt top. Attached Figure Description

[0022] As shown in Figures 1-3, this utility model provides a technical solution: a head-wrapping device for processing T-bolts. A placement frame 12 is fixedly installed at the top center of the processing machine table 1. Limiting rollers 28 are movably installed on both sides inside the placement frame 12. A bidirectional lead screw 21 is rotatably installed on the inner center of the placement frame 12 via a bearing. A servo motor 29 is fixedly installed on the inner side of the hollow frame 2, and the side of the transmission shaft of the servo motor 29 is fixedly connected to the top of the side of the bidirectional lead screw 21 via a coupling. Transmission sleeves 22 are movably sleeved on both sides of the outer side of the bidirectional lead screw 21 via threads. A connecting frame 23 is fixedly installed on the top of the outer side of each transmission sleeve 22. The vertical section of the connecting frame 23 is T-shaped. Slide grooves are opened on the top of both the hollow frame 2 and the processing machine table 1, and the connecting frame 23 is slidably inserted into the slide groove. A fixing frame 24 is vertically fixedly installed on the top surface of each connecting frame 23.

[0023] In this technical solution (as shown in Figures 1, 2, and 3), mounting plates 25 are slidably installed at both ends of the inner side of the placement frame 12. Connecting plates 26 are fixedly installed at both ends of the side of each mounting plate 25. I-shaped rods 27 are rotatably installed between the sides of every two sets of connecting plates 26 via bearings, and limiting rollers 28 are fixedly sleeved on the outer middle surface of the I-shaped rods 27.

[0024] In this technical solution (as shown in Figures 1, 2 and 3), mounting plates 25 are slidably installed on both ends of the inner side of the placement frame 12. Connecting plates 26 are fixedly installed on both ends of the side of each mounting plate 25. I-shaped rods 27 are rotatably installed between the sides of every two sets of connecting plates 26 via bearings, and limiting rollers 28 are fixedly sleeved on the outer middle surface of the I-shaped rods 27.

[0025] In this technical solution (as shown in Figures 1, 2 and 3), a support frame 11 is fixedly installed at the top center of the processing machine table 1. A hydraulic push cylinder 13 is vertically fixedly installed at the top center of the support frame 11. A lifting plate 3 is fixedly installed at the bottom of the piston rod of the hydraulic push cylinder 13. A movable plate 32 is movably fitted onto the bottom surface of each lifting plate 3. An adsorption magnet 31 is fixedly embedded in the bottom center of the lifting plate 3. A movable groove 35 is opened in the middle of the movable plate 32, and the adsorption magnet 31 is movably installed inside the movable groove 35.

[0026] In this technical solution (as shown in Figures 1, 2 and 3), movable rods 33 are vertically fixedly installed on the four corner surfaces of the top of the movable plate 32, and the movable rods 33 are slidably inserted into the inside of the side of the lifting plate 3. A return spring 34 is movably sleeved on the outer surface of each movable rod 33, and the bottom of the return spring 34 is movably attached to the outer wall of the top of the lifting plate 3.

[0027] During operation, the servo motor 29 is turned on via an external control switch, causing it to rotate synchronously with the bidirectional lead screw 21 inside the hollow frame 2. Combined with the rotational transmission action of the bidirectional lead screw 21 on the transmission sleeve 22, this drives the two sets of transmission sleeves 22 to move horizontally in opposite directions within the hollow frame 2. Subsequently, under the connecting transmission action of the connecting frame 23 and the fixed frame 24, the movable plates 32 located at both ends of the inner side of the placement frame 12 move horizontally in opposite directions until they drive the two sets of limit rollers 28 to move synchronously in opposite directions and approach and fit against the outer side of the T-bolt screw to be processed. Then, the hydraulic push cylinder 13 is activated, causing the movable plate 32 and the adsorption magnet 31 at its bottom to descend rapidly. After stamping and shaping the top of the T-bolt, the limit rollers 28... Under the limiting action of the two sides of the bolt, the T-bolt can be limited and prevented from shifting during the stamping process. After the stamping is completed, the magnet 31 attracts the T-bolt, so that it can be moved out of the placement frame 12 with the rotation of the limiting roller 28. With the synchronous vertical movement of the movable plate 32 and the lifting plate 3, until the top of the movable rod 33 contacts the inner wall of the support frame 11, the top of the movable rod 33 is resisted by the inner wall of the support frame 11. At the same time as the movable rod 33 moves vertically outside the lifting plate 3, it pushes the movable plate 32. At the same time as the movable plate 32 moves vertically at the bottom of the lifting plate 3, it pushes the T-bolt outside the magnet 31 and separates it from the bottom of the magnet 31. Then, the bolt of the stamping head is transferred, and the head of the T-bolt is shaped.
