Machining method for small-batch production of O-shaped sealing ring fixing pieces

Abstract

The invention discloses a machining method for small-batch production of O-shaped sealing ring fixing pieces. The machining method comprises the following steps of: a, receiving materials with the sizes of 100 * 60 * 40 and corresponding marks; B, milling the materials to be 90 + / -0.3 * 50 + / -0.3 * 30 + / -0.3 for standby application; C, drilling holes of phi 7 + / -0.2 * 90 in the milled materials, and ensuring that the sizes are 7 + / -0.2 and 4.5 + / -0.1; D, carrying out slow travelling wire cutting according to the sizes of workpiece materials to be machined for standby application; E, carrying out slow travelling wire cutting on the workpiece materials obtained in the step d according to the sizes of workpiece materials to be processed for standby application; and f, polishing the workpiece materials obtained in the step e until the surfaces with the roughness of Ra0.8 are obtained. According to the method, through reasonable discharging, a plurality of gaskets are combined into a workpiece with a large size, so that the problem that a small-size workpiece is difficult to clamp by large equipment is solved, and then stamping is replaced with a slow travelling wire cutting method, so that the problems that clamping is difficult and the size precision is difficult to guarantee are solved.

Description

technical field [0001] The invention relates to a processing method for a small-sized, special-shaped gasket, in particular to a processing method for small-batch production of an "O"-shaped sealing ring fixed piece. Background technique [0002] For enterprises that have used large and medium-sized equipment to produce large and medium-sized parts for many years, it is uneconomical to purchase new equipment if they are temporarily tasked with producing small-sized parts in small batches, and large-scale equipment is often difficult to clamp small-sized workpieces. Clamping accuracy cannot be guaranteed, so how to improve the process and use existing equipment to complete the task is worth discussing; [0003] For curved sheet metal stamping parts, if the size of the part is small, it is often not easy to clamp during stamping. Even if it can be clamped, it is often difficult to guarantee the dimensional accuracy of the part. Therefore, how to improve the process flow and us...
