Problems solved by technology

[0002] At present, most of the traditional production of hydraulic plunger workpieces is still in the semi-automatic stage, and the pass rate of workpiece processing is low, the processing effect of each link is not good, and even the detection of products after heating is an environment that is ignored, resulting in unqualified final products. rate rises, so there is an urgent need for an efficient heat treatment system for hydraulic plunger workpieces

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] Such as Figure 1 to Figure 12 As shown, a system for heat treating a hydraulic plunger workpiece includes the following steps:

[0048]1.1) Pickling and descaling step: Hoist the raw materials, run them through the automatic line into the pickling tank for pickling, and obtain the descaling material, wherein the pickling tank is heated through a natural gas pipeline to ensure a constant temperature; the pickling uses Concentrated hydrochloric acid pickling, the concentration is 18% to 35%, the heating temperature is stable at 55°C to 65°C, and the treatment time is 100 minutes to 180 minutes; the standard after treatment is that the raw material has no scale. The current pickling is not heated, which makes the whole process very limited by the ambient temperature and reduces the pickling effect, especially in winter, the pickling effec...

Abstract

The invention discloses a system for performing thermal treatment on a hydraulic plunger piston workpiece. The system comprises the following steps of: 1.1) removing oxide skin by pickling; 1.2) removing residual acid; 1.3) removing scale incrustation; 1.4) phosphating; 1.5) saponifying; 1.6) performing rough wire drawing; 1.7) nodulizing and thermally circulating; 1.8) cleaning materials; 1.9) performing fine wire drawing; 1.10) performing cold upsetting; 1.11) reshaping products; 1.12) quenching; 1.13) vibrating and grinding; 1.14) demagnetizing; 1.15) performing surface treatment; and 1.16)screening. The invention provides a system for efficiently performing thermal treatment on the hydraulic plunger piston workpiece.

Description

technical field [0001] The invention relates to the field of hydraulic processing, and more particularly to a system for heat-treating hydraulic plunger workpieces. Background technique [0002] At present, most of the traditional production of hydraulic plunger workpieces is still in the semi-automatic stage, and the pass rate of workpiece processing is low, the processing effect of each link is not good, and even the detection of products after heating is an environment that is ignored, resulting in unqualified final products. Therefore, there is an urgent need for an efficient system for heat treatment of hydraulic plunger workpieces. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides a system for heat-treating hydraulic plunger workpieces. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is as follows: [0005] A system for heat treating...
