Embodiment 1

[0032] Processing technology of plane triangle:

[0033] 1) Blank fixing: fix the blank on the workbench;

[0034] 2) Plane rough grinding: Use a 40-mesh surface grinder to carry out plane rough grinding on the upper and lower surfaces of the blank respectively. After the plane rough grinding, the machining allowance of the upper surface of the blank is measured as 0.25, and the machining allowance of the lower surface Measured to be 0.5mm;

[0035] 3) Drilling: Drill the fixed hole 1 and the positioning hole 2 on the blank processed in step 2. The drilling of the fixed hole 1 is done by the machining center, and it is a one-time molding. The absolute error of the fixed hole 1 after punching is 0.05mm , the positioning hole 2 is initially drilled by the machining center, and the machining allowance of the positioning hole 2 after the initial drilling is measured to be 0.25mm;

[0036] 4) Heat treatment: first raise the temperature of the blank treated in step 3 to 700°C and ...

[0051] Processing technology of plane triangle:

[0052] 1) Blank fixing: fix the blank on the workbench;

[0053] 2) Plane rough grinding: Use 80-mesh sand surface grinder to carry out plane rough grinding on the upper and lower surfaces of the blank respectively. After the plane rough grinding, the machining allowance of the upper surface of the blank is measured as the machining allowance of the lower surface of 0.5mm Measured to be 0.25mm;

[0054] 3) Drilling: Drill the fixed hole 1 and the positioning hole 2 on the blank processed in step 2. The drilling of the fixed hole 1 is done by the machining center, and it is a one-time molding. The absolute error of the fixed hole 1 after punching is 0.05mm , the positioning hole 2 is initially drilled by the machining center, and the machining allowance of the positioning hole 2 after the initial drilling is measured to be 0.5mm;

[0055] 4) Heat treatment: first raise the temperature of the blank processed in step 3 to 750°C ...

Embodiment 3

[0070] Processing technology of plane triangle:

[0071] 1) Blank fixing: fix the blank on the workbench;

[0072] 2) Plane rough grinding: Use 80-mesh surface grinder to carry out plane rough grinding on the upper and lower surfaces of the blank respectively. After the plane rough grinding, the machining allowance of the upper surface of the blank is measured as the machining allowance of the lower surface of 0.28mm Measured to be 0.46mm;

[0073] 3) Drilling: Drill the fixed hole 1 and the positioning hole 2 on the blank processed in step 2. The drilling of the fixed hole 1 is done by the machining center, and it is a one-time molding. The absolute error of the fixed hole 1 after punching is 0.05mm , the positioning hole 2 is initially drilled by the machining center, and the machining allowance of the positioning hole 2 after the initial drilling is measured to be 0.42mm;

[0074] 4) Heat treatment: first raise the temperature of the blank treated in step 3 to 730°C and h...

Abstract

The invention provides a flat machine cam processing technology, which aims to solve the problems in the existing flat machine cam processing technology that the precision of a flat machine cam is not high enough, the noise is large in the use process, the service life is short, and the like. The processing technology comprises a plane cam processing technology and a concave-convex cam processingtechnology, wherein the plane cam processing technology comprises the following steps: 1) blank fixation, 2) plane rough grinding, 3) punching, 4) heat treatment, 5) slow wire cutting, 6) plane accurate grinding, and 7) polishing; and the concave-convex cam processing technology comprises the following steps: a) blank fixation, b) plane rough grinding, c) punching, d) first carving of a concave-convex part, e) heat treatment, f) slow wire cutting, g) plane accurate grinding, h) accurate carving of the concave-convex part, and i) polishing. The flat machine cam produced by adopting the technology has the advantages of high precision, high abrasive resistance and low noise, so the flat machine cam processing technology is suitable for processing various flat machine cams.

Description

technical field [0001] The invention relates to a processing technology for flat knitting machine parts, in particular to a flat knitting machine triangle processing technology. Background technique [0002] As a part of the flat knitting machine, the quality of the triangle not only has a certain influence on other parts of the flat knitting machine, but also directly relates to the quality of knitted products. Triangular machining on the market is currently difficult to process after heat treatment, so it is mainly carried out by processing first and then heat treatment. However, since the workpiece is easily deformed after heat treatment, the precision of the obtained triangular products is not high enough, and then in a certain To a certain extent, it hinders the improvement of the quality of knitted products. In addition, due to the inherent precision defects of the products, there is a phenomenon of high noise during use. Contents of the invention [0003] The purpo...
