Description

Technical Field

[0001] This utility model relates to the technical field of cold heading machine components, and in particular to a flexible production cold heading machine clamping mechanism. Background Technology

[0002] The clamping mechanism of a flexible production cold heading machine is a core functional component of cold heading forming equipment. Its core function is to accurately clamp the blank (such as steel wire, bolt, bar stock) during the cold heading process, ensuring that the blank is fixed in position and stable in posture during stamping, bending, forming and other processes, providing reliable positioning for subsequent processing. It is widely used in flexible production scenarios for metal products such as fasteners, automotive parts, and electronic components.

[0003] Currently, the cold heading machine generally requires multi-step forming during the blank processing. In this process, a clamping mechanism is needed to transfer the blank to different workstations. However, the blank undergoes deformation during each processing step. Traditional clamping mechanisms are typically controlled by cylinders. Because the cylinder stroke is fixed, the clamping distance and force cannot be adaptively adjusted according to the actual dimensions of the deformed blank during the blank fixing process. If the cylinder stroke is preset according to the initial blank size, the deformed blank may shrink, resulting in insufficient clamping force and causing slippage or movement during transfer, affecting the accuracy of the workstation transfer. If the clamping force is set too high, it can easily cause secondary damage to the deformed blank, compromising forming accuracy. Therefore, a flexible production cold heading machine clamping mechanism is proposed to solve these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a flexible production cold heading machine clamping mechanism, which can solve the problems mentioned in the background art.

[0033] 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.

[0034] Reference Figures 1-5 This utility model provides an embodiment of a flexible production cold heading machine clamping mechanism, including a mounting plate 1. The mounting plate 1 is provided with a clamping assembly 2 and a moving assembly 3. The clamping assembly 2 includes a fixed frame 21, a protective assembly 23, a moving rod 26, and a positioning adjustment assembly 28. The fixed frame 21 is fixedly connected to the outer wall of the mounting plate 1. A cylinder 22 is fixedly installed on the fixed frame 21. The protective assembly 23 is located on the output end of the cylinder 22. A connecting block 24 is provided at the bottom of the protective assembly 23. The moving rod 26 is slidably connected in the fixed frame 21. The moving rod 26 and the connecting block 24 are hinged by a hinge rod 25. The positioning adjustment assembly 28 is located at the bottom of the moving rod 26. Multiple sets of clamping assemblies 2 are provided. The blank is fixed by multiple sets of clamping assemblies 2, so that the blank can be gradually moved by the moving assembly 3 during subsequent processing, thereby realizing the conversion of the blank processing station.

[0035] Reference Figures 2-3 A positioning rod 27 is fixedly connected to the inner wall of the fixed frame 21. The positioning rod 27 slides in the groove of the moving rod 26. A through groove is provided at the bottom of the fixed frame 21 for the positioning rod 27 to pass through. In this way, the positioning rod 27 can move stably when it is moved by the hinge rod 25.

[0036] Reference Figure 3The positioning adjustment assembly 28 includes a horizontal plate 281, which is fixedly connected to the bottom of the moving rod 26. An electric telescopic rod 282 is fixedly connected to the lower side of the horizontal plate 281. A clamping block 283 is fixedly connected to the telescopic end of the electric telescopic rod 282. The clamping opening of the clamping block 283 is V-shaped. A guide block 284 is fixedly connected to the outer wall of the clamping block 283. The guide block 284 is penetrated by a guide rod 285 and is slidably connected to the guide rod 285. The guide rod 285 is fixedly connected to the lower side of the horizontal plate 281. By retracting the output end of the starting cylinder 22, the connecting block 24 is driven to rise. This, in turn, drives the hinge rod 25 to move, pulling the two sets of moving rods 26 closer together, so that the clamping block 283 can fix the blank. The V-shaped clamping mouth of the clamping block 283 is suitable for blanks of different diameters and shapes. It can quickly adapt to the production needs of multiple varieties without replacing the clamping block 283, greatly shortening the changeover time. Furthermore, for different blanks, the position of the clamping block 283 can be stably adjusted by activating the electric telescopic rod 282, under the action of the guide rod 285 and the guide block 284, which facilitates the subsequent clamping and fixing of different blanks and improves the use effect of the device.

[0037] Reference Figures 3-4 The protective component 23 includes a first connector 231, which is slidably connected to a T-rod 232. A second connector 233 is fixedly connected to the bottom of the T-rod 232. The first connector 231 and the second connector 233 are elastically connected by a return spring 234. The first connector 231 is fixed to the output end of the first cylinder 22, and the second connector 233 is fixed to the connecting block 24. After the two sets of clamping blocks 283 clamp and fix the blank, when the output end of the first cylinder 22 retracts, the return spring 234 is stretched, and the first connector 231 slides relative to the T-rod 232, so that the clamping blocks 283 will not apply excessive pressure to the blank, thereby improving the accuracy and quality of the blank's gradual forming.

[0038] Reference Figure 5 The moving component 3 includes a moving base 31, which is fixed to the mounting plate 1. The moving base 31 is slidably connected to the slide rail 32, which is fixedly connected to the connecting frame 33. A second cylinder 34 is fixedly connected to the outer wall of the connecting frame 33. The output end of the second cylinder 34 is fixed to the moving base 31. The moving base 31 is driven to slide along the slide rail 32 by the second cylinder 34, so as to realize the precise station transfer of the clamping mechanism. It is suitable for multi-station gradual processing of blanks.

[0039] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0040] Working principle: In use, first, according to the initial size of the blank to be processed and the requirements of subsequent forming processes, the initial distance of the clamping blocks 283 is adjusted by the electric telescopic rod 282. The guide block 284 slides smoothly along the guide rod 285 to ensure that the V-shaped clamping mouths of the two sets of clamping blocks 283 are aligned and adapted to the blank specifications. The cylinder 1 22 is started, and its output end retracts, driving the connector 1 231 to rise. The return spring 234 is stretched accordingly, and the connector 233 slides relative to the connector 1 231 through the T rod 232. At the same time, the connector 233 drives the connecting block 24 to rise, and the hinge rod 25 pulls the two sets of moving rods 26 closer to each other along the positioning rod 27, so that the clamping blocks 283 clamp the blank. After the two sets of clamping blocks 283 clamp and fix the blank, when the output end of the cylinder 1 22 retracts, the return spring 234 is stretched, and the connector 231 slides relative to the T rod 232, so that the clamping blocks 283 do not apply excessive pressure to the blank. After initial clamping, cylinder 34 of moving component 3 is activated, driving moving seat 31 to slide along slide rail 32, thereby precisely transferring mounting plate 1 and clamping component 2 to the first processing station. After this process is completed, the blank undergoes a preset deformation. At this time, based on the dimensions of the deformed blank, electric telescopic rod 282 is activated again to fine-tune the spacing of clamping blocks 283, ensuring that the clamping force is adapted to the deformed blank and avoiding slippage or secondary damage. Subsequently, cylinder 34 continues to drive the mechanism to transfer to the next processing station, repeating the above "processing-deformation adaptation-station transfer" process.

[0041] 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.
