Embodiment 1

[0027] The invention discloses a processing technology for oil cylinder pistons. The oil cylinder pistons are made in pairs, and the processing steps are successively blanking, rough turning, semi-finished turning, primary finishing turning, pre-inspection, sawing, secondary finishing turning, drilling and assembling holes and final inspection.

[0028] The concrete steps of above-mentioned oil cylinder piston processing are as follows:

[0029] The first step, blanking: select a round bar φ95mm, cut and blank on a sawing machine, and the blanking length is 102mm;

[0030] The second step, rough turning: the end face of the ordinary lathe is fixed in length and the end face is flat, the outer circle of rough turning is φ90.5mm; then the outer circle of φ90.5mm is turned around, the outer circle of rough turning is φ90.5mm, and the center hole is drilled to φ20mm And blunt the sharp edge of the center hole and remove the burr;

[0031] The third step, semi-finishing: clamping...

Embodiment 2

[0039] In this example, on the basis of Example 1, the rough turning step in the second step is changed, specifically, the end face of the ordinary lathe is fixed in length and flat, and the outer circle of the rough car is φ90.3mm; Outer circle, rough turning outer circle φ90.3mm, drill center hole φ20.5mm, blunt the sharp edge of the center hole and remove burrs.

Embodiment 3

[0041] In this example, on the basis of Example 1, the rough turning step in the second step is changed, specifically, the end face of the common lathe is fixed in length and flat, and the outer circle of the rough car is φ90.0 mm; 0mm outer circle, rough turning outer circle φ90.0mm, drill center hole φ21 mm, blunt the sharp edge of the center hole and remove burrs.

Abstract

The invention relates to an oil cylinder piston processing technology. Oil cylinder pistons are made in pair, and the processing steps sequentially comprise a blanking process, a rough turning process, a half finished turning process, a primary finish turning process, initial inspection, a sawing process, a secondary finish turning process, a pilot hole drilling process and final inspection. During the rough turning process, a 1mm of allowance is left for a central hole, a 0.8mm of allowance is left for a groove, a 1.5mm of allowance is left for the fixed length of the excircle, and a 1mm of allowance is left for the fixed length of the end face. The oil cylinder piston processing technology is advantaged in that the oil cylinder pistons are made in pair, and the pair of oil cylinder pistons is sawed-off to form two pistons, and the piston processing efficiency is improved.

Description

technical field [0001] The invention relates to an oil cylinder piston, in particular to an oil cylinder piston processing technology. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and a liquid discharge device. [0003] Such as Figure 1 to Figure 3 As shown, there is an existing oil cylinder...
