Abstract

In concrete, the present invention relates to a kind of processing method of warm-heating once through compound extrusion-forming for oil cylinder. The extrusion die is also equipped. The bar stock is heated to 750-850 deg.C, after once forming by compound extrusion, and it is made up by three times of extending. Owing to that the oil cylinder of the shock absorber is made by the given method and clamp, so the material consumption is lowered, the yield is high, the quality of the product is ensured, the used equipment is decreased and the working period is shortened.

Description

The manufacture method of tool for oil cylinder of shock absorber for motor vehicle and anchor clamps
The present invention relates to the processing technology of tool for oil cylinder of shock absorber for motor vehicle, the one-time formed processing method of specifically a kind of warm Compound Extrusion, and configuration extrusion die.
At present, for the manufacturing of tool for oil cylinder of shock absorber for motor vehicle, adopt bulk-breaking welding combination and processing method such as cold stamping shaped usually.The former cylinder body is low service life, and raw materials consumption is big, and yield rate is low, does not guarantee product quality; The latter needs equipment tonnage big, and hot mo(u)lding equipment is many, and energy source and power consumption is big, and the used cold-punching mold life-span is short, and cold drawing often, the product process-cycle is long, the cost height, and yield rate is low, does not satisfy user's needs; The technology of above-mentioned two kinds of methods is complicated, and efficient is low.
The objective of the invention is the shortcoming at above-mentioned existence, provide a kind of processing tool for oil cylinder of shock absorber for motor vehicle technology simple, used raw materials consumption is little, method that product quality is high and anchor clamps.
Technical essential of the present invention is: get warm 750~850 ℃ of bar, after the Compound Extrusion one-shot forming, extend for three times and to make; The used anchor clamps of Compound Extrusion by the cope match-plate pattern counterdie, dash, ejector beam and material returned pull bar etc. constitute, it is characterized in that cope match-plate pattern crosses the lead sliding sleeve of a side and link to each other with counterdie, the opposite side of cope match-plate pattern counterdie joins through material returned pull rod screw, the inner face centre of patrix installs and dashes, on the lower bolster fixing lower mode cavity with towards corresponding, material returned pull bar and ejector beam all are fixed on the supporting plate.
Because the processing method and the anchor clamps that adopt the present invention to provide are made tool for oil cylinder of shock absorber, make its raw-material consumption reduce, the yield rate height, product quality is guaranteed; Device therefor reduces, and the process-cycle of product is short.Its manufacture method is simple, and used clamp structure is simple, and easy operating has alleviated operator's labour intensity, and is easy to utilize.
Accompanying drawing is the used clamp structure schematic diagram of the present invention.
During work, when rising to the press slide dead point towards (4) with cope match-plate pattern (5), will put into counterdie (2) chamber by warm 750~850 ℃ of blanks of bar of tool for oil cylinder size intercepting, it is descending to start press slide, and upper punch (4) is with the blank extrusion modling.Dash (4) when returning, workpiece (3) is stayed in the lower mode cavity (2), and cope match-plate pattern (5) drives material returned pull bar (6) and ejector beam (1) ejects counterdie (2) with workpiece.(7) among the figure are supporting plate.
The given method of the present invention unlike the prior art be that forward extrusion, backward extrusion are simultaneously Carry out (cope match-plate pattern, counterdie are worked simultaneously), the unit pressure of backward extrusion is greater than the unit of forward extrusion Pressure. Backward extrusion pressure 50~60Kg/mm2, forward extrusion power 30~40Kg/mm2 The Compound Extrusion part Stressed evenly metal inside is organized and is not damaged, and improves toughness of products and intensity, guarantees product matter Amount; Compound Extrusion is cold, and to draw number of times few, and its ratio 1: 50 forms the garden tube of thin-walled, wall pressure 1.5m/m ( Internal diameter φ 48m/m, external diameter φ 51m/m).

Claims (3)

1. the manufacture method of a tool for oil cylinder of shock absorber for motor vehicle is characterized in that getting warm 750~850 ℃ of bar, after the Compound Extrusion one-shot forming, extends for three times and to make.
2. anchor clamps of using of method according to claim 1, it is characterized in that it by cope match-plate pattern, counterdie, dash, ejector beam and material returned pull bar etc. constitute, cope match-plate pattern (5) links to each other with counterdie (2) by the lead sliding sleeve of a side, cope match-plate pattern (5) joins through material returned pull rod screw with the opposite side of counterdie (2), the inner face centre of cope match-plate pattern (5) installs and dashes (4), counterdie (2) chamber fixing on the lower bolster is with corresponding towards (4), and material returned pull bar (6) and ejector beam (1) all are fixed on the supporting plate (7).
3. in accordance with the method for claim 1, when it is characterized in that the processing cylinder body running, forward extrusion, backward extrusion are carried out simultaneously, and cope match-plate pattern, counterdie are worked simultaneously, and the unit pressure of backward extrusion is greater than the unit pressure of forward extrusion; Backward extrusion power is 50~60kg/mm 2, forward extrusion power is 30~40kg/mm 2
