A processing method for tooling fixture

Abstract

The invention provides a machining method of a tool jig. The method comprises the steps that 1, material preparation is carried out, wherein a blank is prepared according to machining requirements; 2, plane rough milling is carried out, wherein the blank is fixed to a machine tool to be roughly milled; 3, rough grinding is carried out, wherein the blank is fixed to a middle grinding machine for contour rough machining and grinding; 4, numerical control center rough milling is carried out, wherein a numerical control machining center carries out inner groove milling, carries out drilling and carries out prechamfering to the size, edges to be cut are milled in the inner groove, and no margin is reserved; 5, heat treatment is carried out; 6, flat grinding is carried out, wherein the blank is fixed to a small grinding machine for inner groove detection hardness face grinding, and impurities are ground and removed till the material is polished; 7, hardness detection is carried out; 8, fine grinding is carried out, wherein the blank is fixed to the middle grinding machine to be ground, six contour faces are ground to ensure the planeness and roughness of the faces; 9, fine grinding is carried out, wherein the blank is fixed to a small grinding machine for inner groove fine grinding; and 10, low-speed wire cutting is carried out, wherein edges are cut, and chamfering is carried out. By the adoption of the method, tool abrasion can be effectively reduced, machining time can be saved, and meanwhile product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of processing technology, in particular to a processing method of a tooling fixture. Background technique [0002] With the rapid development of factory automation, automated production applications have been slowly promoted in the industry. When processing tooling fixtures, such as tooling fixtures used on the production line, the requirements for tooling fixtures are often very high. The existing technology often needs to heat treat the workpiece, and then perform digital milling after the heat treatment to cut out the shape and shape we need; but often because the material of the workpiece will become harder after heat treatment, and burrs are prone to appear at the lead angle, so for The material requirements of the tool are very high, and the tool is very prone to wear and damage during the processing process, so the cost of the material consumption is also greatly increased. In view of this, this case...

Problems solved by technology

The existing technology often needs to heat treat the workpiece, and then perform digital milling after the heat treatment to cut out the shape and shape we need; but often because the material of the workpiece will become harder after heat treatment, and burrs are prone to appear at the lead angle, so for The material requirements of the tool are very high, and the tool is very prone to wear and damage during the processing process, so the cost of the material consumption is also greatly increased. In view of this, this case proposes to mill the edges and drill the chamfer before the heat treatment. After heat treatment, the method of cutting edges and chamfering by grinding machine or slow wire walking can achieve better income
