Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a bolt thread rolling machine with high protection. Background Art

[0002] The bolt thread rolling machine is a multifunctional cold extrusion forming machine tool. According to the number of axes, the bolt thread rolling machine can generally be divided into a two-axis thread rolling machine and a three-axis thread rolling machine. The thread rolling machine can perform thread, straight grain, and twill rolling on the workpiece in the cold state within its rolling force range, rolling of spur gears, helical gears and helical spline gears, straightening, reducing diameters, rolling and various forming rolling. When factories produce bolts, screws and other components, bolt thread rolling machines are usually used. The pressure of the rollers on both sides is used to extrude the texture on the surface of the workpiece, which is convenient and fast. The thread rolling cold rolling process is an advanced non-cutting process that can effectively improve the intrinsic and surface quality of the workpiece. The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece. It is an ideal process with high efficiency, energy saving and low consumption.

[0003] The existing bolt thread rolling machine requires manual loading and unloading of materials, which is very time-consuming and labor-intensive. When the workers are unloading materials, the rolling wheels are exposed and they may be pinched if they are not careful. In addition, when the bolt thread rolling machine is processing the bolts, material chips may fly out of the bolts, which may easily cause injuries to the workers and have very low safety.

[0004] Based on the above situation, the utility model proposes a bolt thread rolling machine with high protection. Utility Model Content

The base is fixedly connected to the main body, the main body is fixedly connected to the connecting frame, the main body is provided with the protective mechanism, and the base is provided with the feeding mechanism.

[0007] Furthermore, the protective mechanism includes a rounded corner cover, a limit frame, a connecting block and a large reset spring. A limit frame symmetrically distributed on the left and right is fixedly connected between the base and the main body. The limit frame is slidably connected to the connecting block. A large reset spring is fixedly connected between the connecting block and the limit frame. A rounded corner cover is fixedly connected between the paired connecting blocks, and the rounded corner cover is slidably connected to the main body.

The main body 2 is fixedly connected to the top of the base 1, and the connecting frames 3 are fixedly connected to the left and right sides of the main body 2. The main body 2 is provided with a protective mechanism, and the base 1 is provided with a feeding mechanism.

[0027] like Figure 3 and Figure 5 As shown, the protective mechanism includes a rounded corner cover 5, a limit frame 8, a connecting block 801 and a large reset spring 9. A limit frame 8 symmetrically distributed on the left and right is fixed between the rear side of the base 1 and the rear side of the main body 2. A connecting block 801 is slidably connected to the limit frame 8. A large reset spring 9 is fixed between the connecting block 801 and the limit frame 8. A rounded corner cover 5 is fixed between the paired connecting blocks 801. The rounded corner cover 5 is used to block debris generated during the bolt processing process. The rounded corner cover 5 is slidably connected to the main body 2.

[0028] like Figure 3 and Figure 4As shown, the feeding mechanism includes a hollow slide 4, a sliding frame 6 and a first cylinder 7. The hollow slide 4 is fixedly connected to the top of the base 1, the sliding frame 6 is slidably connected to the front side of the hollow slide 4, the first cylinder 7 is fixedly connected to the bottom of the hollow slide 4, and the output end of the first cylinder 7 is fixedly connected to the sliding frame 6. The sliding frame 6 is used to feed the bolt thread rolling machine.

[0029] like Figure 6 and Figure 7 As shown, it also includes a rounded frame 10, a contact wheel 11 and a small reset spring 12. The rounded frame 10 is slidably connected to the top of the rounded cover 5, and a small reset spring 12 is fixed between the rounded frame 10 and the rounded cover 5. The bottom of the rounded frame 10 is rotatably connected to a pair of contact wheels 11 distributed longitudinally front and back.

[0030] like Figure 8 As shown, it also includes a bottom plate 13 and a second cylinder 14. The bottom of the base 1 is slidably connected to the bottom plate 13.

After the thread rolling machine is repaired, the handle is released, and the rounded corner cover 5 and the connecting block 801 will move downward and return to their original positions under the action of gravity and the reset of the large reset spring 9. The rotation of the bolt will drive the contact wheel 11 to rotate. The bolt continues to move backward until the processing is completed, and it will separate from the contact wheel 11 and slide out of the circular hole on the rear side of the rounded corner cover 5. At this time, the contact wheel 11 and the rounded corner frame 10 move downward and return to their original positions under the action of gravity and the reset of the small reset spring 12.
