Processing method for bed die ferrules

Abstract

The invention relates to a processing method for bed die ferrules. The processing method is characterized by comprising the following steps of: grouping all ferrules according to the number of oil tanks, wherein each group of ferrules form one aggregate and each aggregate is processed with one blank; conducting rough processing, semi-refined processing and thermal treatment between the rough processing and semi-refined processing; drilling threading holes for line cutting and completing processing of other hole-shaped elements; conducting quenching thermal treatment; conducting finish processing of end surface of a disc, and carrying out qualitative thermal treatment; and cutting the disc into single pieces with a line cutting method. The processing method has the advantages of eliminating the quenching deformation of single parts, controlling the out-of-roundness of each single part to be within 0.07 and meeting the design precision requirement by adopting a multi-piece integrated processing manner, as well as removing repeatedly complicated processing procedures of single parts, reducing cutting quantity, improving the utilization rate of materials to 70% from original 30%, and further saving a great quantity of raw materials. In addition, the complicated tuning processing can be omitted, local process flows can be adjusted at any time according to change of production fieldconditions so as to be adapted to the needs of modern production.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for a bottom die collar of a quenching press. Background technique [0002] Quenching press is the leading product of auxiliary equipment in the complete series of gear processing equipment. The complete set of bottom mold collar is the key part of the machine tool, which is equivalent to the workbench of a general machine tool. The bottom mold collar is composed of 16 rings that surround in turn. The complete set of combinations is as follows: Figure 1a with Figure 1b shown. The material used is a high-quality alloy structural steel, which has been produced by single-piece processing for many years. A single part of the component is shown in Figure 4. From the shape of the single part, it can be clearly found that the part is easily deformed after quenching, and the deformation is difficult to control and eliminate. Therefore, t...
