Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, specifically a bolt processing mold. Background Technology

[0002] Cold heading dies are molds used on cold heading machines. Their main function is to cut, pre-shape, and form blanks into cold-formed parts. They are widely used in machinery manufacturing, especially in the production of standard fasteners such as bolts, screws, nuts, rivets, and pins.

[0003] For example, a bolt processing die with authorization announcement number "CN211360321U" uses a universal fine-brush upper die, fine-brush lower die, and pin punch for one-punch and four-punch processing, saving die costs and improving work efficiency. However, it is inconvenient to quickly unload the processed bolts during use, making it difficult to continuously process bolts after processing one bolt. Furthermore, the device requires sensor detection, making it inconvenient to quickly change and position the die. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of inconvenience in continuous processing and mold replacement of the device, and to propose a bolt processing mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a bolt processing mold, including a bracket and a platform. The platform is fixedly connected to the left end of the bracket, and support plates are symmetrically fixedly connected to the right end of the bracket. The inner walls of the support plates are rotatably connected to both ends of a rotating rod through bearings. The upper end of the rotating rod is fixedly connected to the output shaft of a motor. The motor is threadedly connected to the support plate on one side through multiple screws. The surface of the platform is provided with a clamping structure. The right end of the bracket is provided with a discharge device. A winding wheel is fixedly connected to the outer wall of the rotating rod.

[0007] Preferably, the clamping structure includes bolts and a pressure plate, the outer wall of the pressure plate abutting against the platform, and the pressure plate is threadedly connected to the platform by two bolts.

[0008] Preferably, the pressure plate abuts against the mold through an arc surface, and the outer wall of the mold abuts against the platform.

[0009] Preferably, the discharge device includes a straight rod and a push plate. The outer wall of the straight rod is slidably connected to a through hole on the surface of the support. One end of the straight rod is fixedly connected to the push plate, and another end of the straight rod is fixedly connected to a circular plate. The circular plate and the support are respectively fixedly connected to both ends of a tension spring, and the right end of the circular plate is fixedly connected to one end of a pull rope.

[0010] Preferably, one end of the pull rope is fixedly connected to the reel, and the outer wall of the push plate matches the groove opened on the surface of the bracket.

[0011] Preferably, the mold has a through hole inside, and one end of the mold is abutted against the support.

[0012] The bolt processing mold proposed in this utility model has the following advantages: by cooperating with the discharge device and the bracket, the output shaft of the motor is controlled to rotate in the reverse direction, so that the tension spring is released and the push plate can push the processed bolt material out of the mold. The bolt material can then be inserted into the mold again for processing. By pushing the processed bolt material out of the mold, the operator can insert the material into the mold for continuous processing.

[0013] By using the clamping structure and platform, the operator can remove the bolts on both sides, allowing the pressure plate to be removed. The operator can then remove the mold, replace it with a mold of different inner diameter, and position it by fitting it against the arc groove on the platform surface. At the same time, one end of the mold is fitted to the bracket, and the pressure plate is fixed by the bolts on both sides, thus completing the mold replacement. This device allows for convenient and quick mold replacement by positioning and fixing the mold. Attached Figure Description

The platform 5 is fixedly connected to the left end of the bracket 1, and the support plate 3 is symmetrically fixedly connected to the right end of the bracket 1. The inner walls of the support plate 3 are rotatably connected to both ends of the rotating rod 7 through bearings. The upper end of the rotating rod 7 is fixedly connected to the output shaft of the motor 6. The motor 6 is a servo motor, and the model is determined according to actual needs to meet the work requirements. The motor 6 is threadedly connected to the support plate 3 on one side through multiple screws. The surface of the platform 5 is provided with a pressing structure 9. The right end of the bracket 1 is provided with a discharge device 2. The outer wall of the rotating rod 7 is fixedly connected with a roller 8.

[0023] The pressure plate 902 abuts against the mold 4 through the arc surface opened on its surface. The outer wall of the mold 4 abuts against the platform 5. One end of the pull rope 201 is fixedly connected to the winding wheel 8. The outer wall of the push plate 205 matches the groove opened on the surface of the bracket 1. The mold 4 has a through hole inside. One end of the mold 4 abuts against the bracket 1.

[0024] The clamping structure 9 includes bolts 901 and a pressure plate 902. The outer wall of the pressure plate 902 abuts against the platform 5. The pressure plate 902 is threadedly connected to the platform 5 by two bolts 901.

[0025] The discharge device 2 includes a straight rod 204 and a push plate 205. The outer wall of the straight rod 204 is slidably connected to a through hole on the surface of the support 1. One end of the straight rod 204 is fixedly connected to the push plate 205, and one end of the straight rod 204 is fixedly connected to a circular plate 202. The circular plate 202 and the support 1 are respectively fixedly connected to both ends of the tension spring 203. The elastic coefficient of the tension spring 203 is determined according to actual needs and meets the working requirements. The right end of the circular plate 202 is fixedly connected to one end of the pull rope 201, which is made of nylon.

[0026] Working principle:

[0027] When machining bolts:

[0028] Install this device into the cold heading machine, aligning the mold 4 within the device with the cold heading head of the cold heading machine. Control the motor 6 to operate, causing the output shaft of the motor 6 to rotate, driving the rotating rod 7 to rotate synchronously. This rotating rod 7 then drives the winding wheel 8 to move synchronously, allowing the winding wheel 8 to wind up the pull rope 201. The pull rope 201 then pulls the circular plate 202 and the straight rod 204 to move synchronously, causing the straight rod 204 to drive the push plate 205 into the groove on the surface of the support 1. Simultaneously, the tension spring 203 is stretched, inserting the straightened bolt material into the mold 4, so that one end of the bolt material is aligned with the push plate. 205 Surface is pressed tightly, cold heading machine is started to cold head the bolt material. The die is used to compress and form a transition shape between the thin rod and the large step, reserving material for the head forming. The head outline is initially headed by a second stamping, the direction of metal flow is optimized, and the die precisely impacts the blank to complete the final shape of the bolt head and rod, ensuring continuous distribution of metal fibers to improve strength. After processing, the output shaft of motor 6 is controlled to rotate in reverse, so that tension spring 203 is released, and push plate 205 can push the processed bolt material out of the mold 4. The bolt material is then inserted into the mold 4 again for processing.

[0029] Mold change process:

[0030] The operator rotates and removes the bolts 901 on both sides, allowing the pressure plate 902 to be removed. The operator then removes the mold 4 and replaces it with a mold 4 of different inner diameters. The mold 4 is then positioned by fitting it into the arc groove on the surface of the platform 5. At the same time, one end of the mold 4 is fitted into the bracket 1, and the pressure plate 902 is fixed by the bolts 901 on both sides, thus completing the replacement of the mold 4.

[0031] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
