Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a local roughening tool. Background Art

[0002] When it is necessary to perform local upsetting processing on rod-shaped parts, the traditional processing method generally adopts the overall manufacturing and processing forming scheme, turning a large cylindrical metal rod on a lathe. Turning the blank into a finished product requires cutting off a large amount of raw materials, which increases the processing cost of the parts; at the same time, it takes a long time to process each part, which makes the processing efficiency of the parts low, which is not conducive to the rapid mass production of parts. Upsetting is a forging process that reduces the height of the blank and increases the cross-section. If the partial cross-section of the blank is increased, it is called local upsetting. When upsetting, it should be noted that the end face of the blank should be flat and perpendicular to the axis, and the forging force should be positive, otherwise it is easy to forge crooked; the upsetting force should be large enough, otherwise it will form a thin waist or interlayer.

A hydraulic cylinder is provided on the mounting plate, and the piston rod of the hydraulic cylinder is detachably connected to a roughing head. A symmetrical guide rod is provided on the mounting plate, and the end of the guide rod is arranged in the hollow rod clamping mechanism.

This design facilitates the replacement of the roughing head and is suitable for use with hollow rods of different specifications. The roughing head is stable during movement to ensure the quality of roughing.

[0004] However, the above technical solution has the following defects: in the above hollow rod end roughing tooling, two fixing blocks are used to clamp the round rod, but the sizes of the fixing blocks are fixed, and the roughing area cannot be adjusted, which is inconvenient to use.
