A processing method for an air shovel cylinder block

Abstract

The invention relates to a processing method of an air shovel cylinder body, the cylinder is especially a 190 air shovel cylinder, and the method comprises the following steps: 1. Prepare materials, and use a sawing machine to saw the blanks of the cylinder head and the cylinder body. Second, drilling processing. 3. Lathe processing: CNC lathe is used to finish the inner hole and both ends of the cylinder body, and the outer circle, inner hole and both ends of the cylinder head. Fourth, extrusion processing. 5. Welding forming, welding cylinder head and cylinder body. 6. Lathe processing, processing the cylinder head and cylinder body. 7. Rolling processing to obtain the thread required for the product. Eight, extrusion processing. Nine, heat treatment. 10. Surface treatment. By adopting the method for processing the block of the air shovel cylinder in sections, the inner diameter of the gas path of the block can be stabilized, thereby achieving the effect of stable power output.

Description

technical field [0001] The invention relates to a processing method for an air shovel cylinder body, the cylinder is especially a 190 air shovel cylinder. Background technique [0002] The air shovel is a kind of pneumatic tool with the functions of shoveling, hammering, punching, slotting, etc. It is multi-purpose, mainly used for sand cleaning of castings and deburring of large, medium and small castings, and can correct stone and concrete walls and bricks. The opening work of the wall, etc., the air shovel uses compressed air as the power to make the piston inside the cylinder reciprocate, and the piston drives the shovel to reciprocate, so that the shovel can chisel metal and building materials. In the prior art, when processing the hole E of the air channel of the cylinder block, a twist drill is used to drill in from the outside of the cylinder block. Since the processed hole is relatively deep and obliquely passes through the cylinder block, the position of the hole E...

Problems solved by technology

In the prior art, when processing the hole E of the air channel of the cylinder block, a twist drill is used to drill in from the outside of the cylinder block. Since the processed hole is relatively deep and obliquely passes through the cylinder block, the position of the hole E may be different. Because of deviation, the shape of the intersecting part of the air inlet and the hole E is inconsistent, resulting in inconsistent inner diameters, larger or smaller inner diameters will reduce the power output of the air shovel, resulting in an increase in the defective rate of the finished product. The processing method of the cylinder block of the shovel cylinder adopts the segmented processing method, and by changing the processing technology, the inner diameter of the cylinder air path is stable, so as to achieve the effect of stable power output
