Abstract
The invention relates to a powder metallurgy forming die of a piston of a damper. The powder metallurgy forming die comprises an upper die punch, a first lower punch, a second lower punch, a female die and a mandrel, wherein the second lower punch sleeves the mandrel, the first lower punch sleeves the second lower punch, the female die sleeves the first lower punch and is fixedly mounted on a female die plate, the upper die punch is fixedly mounted at the lower end of the upper die punch plate, the lower end of the first lower punch is fixedly connected with a first lower punch floating plate, the lower end of the second lower punch is fixedly connected with a second lower punch floating plate, a die frame fixing plate is arranged below the second lower punch floating plate, and a mandrel floating air cylinder is arranged below the die frame fixing plate and connected with the mandrel. The powder metallurgy forming die is simple in structure and capable of pressing and forming powder metallurgy at one step, product accuracy is improved, batch production of the piston of the damper is realized, production efficiency is improved, and manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of powder metallurgy forming mould of shock absorber piston, belong to powder metallurgy die manufacturing technology field.
Background technology
Shock absorber piston is parts important in damper, and its hardness, intensity and wearability and measure of precision are had to very high requirement.Traditional common employing casting processing mode system, dimensional accuracy is lower, need to carry out subsequent technique processing, and the parts percent defective processing is higher.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of simple in structurely, production efficiency is high, can one-shot forming batch production shock absorber piston and the powder metallurgy forming mould of the high a kind of shock absorber piston of Product Precision.
The technical solution adopted in the present invention is for this reason: comprise upper punch, next punching, following two punch, former and plug, described following two punch is enclosed within plug outside, next punching is enclosed within following two punch outside, former is enclosed within next punching outside and is fixedly mounted on negative template, upper punch is fixedly mounted on patrix punching lower end, next sweeps away end and is fixedly connected with next and rushes float plate, following two punch lower end is fixedly connected with following two punch float plate, following two punch float plate below is provided with mould bases fixed head, and mould bases fixed head below is provided with plug floating cylinder and is connected with plug.
Between described plug and plug floating cylinder, be provided with mandrel holder.
Advantage of the present invention is: the present invention can be once compressing by powder metallurgy, improved Product Precision; Can produce shock absorber piston in batches, improve production efficiency and reduced manufacturing cost.
