The spacing compacted products of tool correct the depth of parallelism of product, and mechanical press is made up of upper punching 1, undershoot 5, plug 2 and middle mould 4, a mould
One shaping goes out pad 3.For the product that depth-width ratio is more or less the same, can preferably correct parallel by certain reduction in height
Degree, but, product larger for external diameter it is relatively thin (<Gasket product 3mm), due to resilience, the depth of parallelism is difficult to correct.
Mechanical press shaping is to realize that compacting is acted by toggle, does not have pressurize to move in the bottom dead centre of compacting
Make；And small tonnage mechanical press pressure is smaller, it is impossible to provide larger pressurize；And if realizing pressurize with hydraulic press, then equipment
Efficiency is very low.How on the premise of efficiency is not reduced, pressurize higher is provided in reforming process to correct the flat of thin product
Row degree, is the problem of the art needs solution.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of machinery pressure of efficient gasket powder metallurgy product
Precision truing mechanism processed.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of reshaping device of gasket powder metallurgy product, including upper punching, the upper punching is connected with rushes hanging block, described
On rush hanging block and be connected with floating punch, the floating punch rushes hanging block relative on freedom of movement；In the floating
Drift lower section is provided with the cushion block for placing shaping product, and the cushion block side is provided with height block, and the height block is higher than pad
Block.Position is adjustable between the cushion block and height block.The cushion block is arranged with base.
Hanging block and floating punch are rushed on described and are connected by breathing out not contiguous block, on to rush hanging block, floating punch equal in junction
For stepped, the two ends of the Kazakhstan not contiguous block are respectively provided with protuberance, and the protuberance is clasped and rushes hanging block, floating punch even
The stepped position at the place of connecing by so that rush hanging block and floating punch connection；Hanging block contact position is rushed with, the floating punch is
Arc-shaped, makes floating punch have freedom of movement in Harvard contiguous block.
After cushion block is placed on after the powder metallurgy pad of shaping, press is pushed, and part is rushed in drive descending；On rush hanging block
Connected by breathing out not contiguous block with floating punch, floating punch has appropriate freedom；Floating punch is descending to touch height block
When, due to free floating, can completely be fitted with height block, with ensure shaping cavity space highly for product highly, apply one
Fixed pressure and pressurize, correct product parallelism error.
The present invention solves the problems, such as that the parallelism tolerance of product during mechanical press shaping is uncontrollable and unstable, shaping energy
Power is greatly improved.The depth of parallelism of shaping product depends on the machining accuracy of cushion block and block, eliminate press in itself precision to whole
The influence of shape product parallelism tolerance, it is to avoid the requirement of buying high accuracy press, saves cost.And single shaping can be
Multiple is placed on cushion block and treats shaping product, substantially increase shaping efficiency, it is to avoid the shortcoming of hydraulic press slow motion.
