Description

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

Technical Field

The invention relates to a method for processing small-size special-shaped gaskets, in particular to a method for processing O-shaped sealing ring fixing pieces in small-batch production.

Background

For enterprises which use large and medium-sized equipment to produce large and medium-sized parts for years, if the task of producing small-sized parts in small batches is temporarily received, adding new equipment is uneconomical, and the large-sized equipment is often difficult to clamp small-sized workpieces and cannot ensure the clamping precision, so how to finish the task by improving the process flow and utilizing the existing equipment is worth discussing;

for bent plate stamping parts, if the size of a part is small, the part is not easy to clamp during stamping, even if the part can be clamped, the size precision of the part is difficult to guarantee, so that the problem of clamping is solved and the size precision is guaranteed by improving the process flow and replacing stamping with other processing methods, which is worthy of discussion.

Disclosure of Invention

The invention aims to solve the problems of difficulty and difficulty in machining of the small-size special-shaped gaskets, and provides a method for combining a plurality of gaskets into a workpiece with a larger size through reasonable material discharge so as to solve the problem that large equipment is difficult to clamp the small-size workpiece, and then replacing punching by a slow-running wire cutting method so as to solve the technical problems of difficult clamping and difficult guarantee of size precision.

In order to solve the technical problems, the invention adopts the following technical scheme:

a processing method for small-batch production of O-shaped sealing ring fixing pieces comprises the following steps:

a. selecting materials with the size of 100 multiplied by 60 multiplied by 40 corresponding to the brand;

b. milling the selected material on a milling machine to the size of 90 plus or minus 0.3 plus or minus 50 plus or minus 0.3 plus or minus 30 plus or minus 0.3 for later use;

c. drilling holes with the diameter of 7 +/-0.2 multiplied by 90 on a vertical machining center by using the milled material, and ensuring the sizes to be 7 +/-0.2 and 4.5 +/-0.1;

d. c, performing slow-running wire cutting on the material drilled with the hole in the step c for later use on an electric spark numerical control wire cutting machine according to the size of the workpiece material to be processed;

e. d, cutting the workpiece material obtained in the step d on a slow-moving wire on an electric spark numerical control linear cutting machine for later use according to the size of the workpiece material to be processed;

f. and e, polishing the workpiece material obtained in the step e until the roughness of the workpiece material reaches Ra0.8. The beneficial effect of adopting above-mentioned technical scheme is:

according to the invention, through reasonable material arrangement, a plurality of gaskets are combined into a workpiece with a larger size, so that the problem that small-size workpieces are difficult to clamp by large-scale equipment is solved, and then the problems that clamping is difficult and size precision is difficult to guarantee are solved by replacing stamping with a slow-running wire cutting method.
