Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of roller forging die processing, and in particular relates to a roller forging die lathe processing clamping tool. Background Art
[0002] The roll forging die has an arc shape. The roll forging cavity will wear during the production process. When the wear is serious, the roll forging cavity needs to be planed off and then welded with mold welding materials. After the roll forging die cavity is welded, the surface is irregular and uneven, and the hardness reaches HRC58-62. The current processing method is to directly CNC process after welding. When writing the processing program, the highest point of the welding is set as the starting surface of the machining blank, that is, the machining allowance is large, and the hardness is extremely high. The feed amount each time is extremely small, resulting in a long processing cycle. To solve this problem, we adjusted the CNC processing to turning + CNC processing, but due to the special structure and shape of the roll forging die, it is not easy to clamp and position directly during turning. Utility Model Content
[0003] The utility model aims to provide a roll forging die lathe processing clamping tool to solve the problems raised in the above background technology.

[0005] Preferably, the lower surface of the fixed plate and the upper surface of the movable plate are provided with the same slope as the upper and lower sides of the roller forging die.
[0006] Preferably, the center of the snap ring 1 is threadedly connected to the nut, and the lower end of the snap ring is provided with the same slope as the upper and lower sides of the roller forging die. The snap ring 2 is the same as the snap ring 1 except that the center circle diameter is larger than the center circle diameter of the snap ring 1.
[0007] Technical effects and advantages of the utility model:
[0008] The fixed plate and the movable plate are provided to solve the problem that the roll forging die is difficult to clamp, and two pieces can be clamped at one time.
[0009] Since the first and second clamping rings play a limiting role when the roll forging die is clamped, the first clamping ring is threadedly connected to the screw rod, and the first and second clamping rings of different sizes can be replaced according to the roll forging dies of different thicknesses, thereby improving the versatility of the clamping tooling.
