Abstract
The utility model discloses an air exhaust structure of a full-automatic hydraulic press for powder products. The air exhaust structure comprises a substrate, a male die is connected on the substrate and has a hollow cylinder shape, and the substrate has an air exhaust hole communicated with an inner cavity of the male die. According to the air exhaust structure of the full-automatic hydraulic press for powder products, air between a female die and the male die is exhausted from the air exhaust hole on the substrate after flowing through the inner cavity of the male die, simultaneously air in powder can also be exhausted without machining open bores on the male die, so that all male dies can be directly connected on the substrate, thus saving the procedure of machining open bores on all the male dies, and simultaneously ensuring the evenness of the male dies and enabling the service lives to be longer; and a protective ring is arranged between the male die and the substrate, and the protective ring is sheathed on the male die, thus avoiding the phenomena that when the product is pressed, the male die is pressed to explode and metal scatters around and hurts people due to overlarge pressure.
Description
Technical field
The utility model relates to a kind of mold component of fully automatic powder product hydraulic press, specifically is meant the exhaust structure of fully automatic powder product hydraulic press.
Background technology
Powder metallurgy be produce metal or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through being shaped and sintering, make the technology of metal material, compound and all kinds goods.Powder metallurgy has unique chemical to be formed and machinery, physical property, and these performances are can't obtain with traditional casting method.The utilization PM technique can directly be processed porous, half fine and close or full dense material and goods, like oiliness bearing, gear, cam, guide rod, cutter etc., is a kind of Cutting Process that do not have less.1 PM technique can reduce alloying component to greatest extent gathers partially, eliminates thick, uneven cast sturcture.Has important effect at preparation high-performance rare-earth permanent magnet material, rare earth hydrogen storage material, rare earth luminescent material, rare earth catalyst, high temperature superconducting materia, new metallic material (like Al-Li alloy, heat-resisting Al alloy, superalloy, powder corrosion resisting stainless steel, powder high-speed steel, intermetallic compound high-temperature structural material etc.); 2 can prepare the non-equilibrium materials of a series of high-performance such as amorphous, crystallite, accurate brilliant, nanocrystalline and over-saturation solid solution, and these materials have electricity, magnetics, optics and the mechanical property of excellence; 3 can easily realize polytype compoundly, give full play to each group element material characteristic separately, are the technologies of a kind of low-cost production high-performance metal base and ceramic composite; 4 can produce material with special construction and performance and the goods that common smelting process can't be produced, like novel porous biomaterial, and porous diffusion barrier material, high performance structure ceramic grinding tool and ceramic material etc.; 5 can realize nearly clean shape and the automatic batch production of forming, thereby, can reduce the resource and the energy resource consumption of production effectively; 6 can make full use of ore, mine tailing, steel-smelting sewage sludge, steel scale of steel rolling, the recovery waste metal is made raw material, is a kind of new technology that can effectively carry out material regeneration and comprehensive utilization.The machine tool that we are common, the five metals grinding tool much is exactly that PM technique is made.Production process: 1 produces powder, and the production process of powder comprises the mixing and other steps of the producing of powder, powder.For mouldability and the plasticity of improving powder adds plasticizer such as gasoline, rubber or paraffin usually; 2 compression mouldings, powder is pressed into required form under 500 ~ 600MPa pressure; 3 sintering carry out in the high temperature furnace of protective atmosphere or vacuum drying oven.Sintering is different from metal molten, and it is solid-state to have at least a kind of element still to be in during sintering.Pass through series of physical chemical processes such as diffusion, crystallization again, melting welding, chemical combination, dissolving in the sintering process between powder particle, become metallurgic product with certain porosity; 4 post processings, generally speaking, the product that sinters can directly use.But high and have the product of high hardness, wearability also will carry out the sintering post processing for some dimensional requirement precision, post processing comprises pressure-sizing, roll extrusion, extruding, quenching, surface hardening, immersion oil, and infiltration etc.
Present in production technology; Usually adopt the fully automatic powder hydralic stamping press to realize the purpose of punching press, in powder, have certain air, in punching press; After being stamped, powder forms product; While air portion within it also is compressed, and on the end face of grinding tool, offers exhaust outlet usually, the air when being used to discharge compression.Brought another problem simultaneously: all will offer exhaust outlet on each punch, so, not only processing capacity increases, and bigger to the damage of mould, is unfavorable for the service life of punch.
The utility model content
The purpose of the utility model is to provide a kind of exhaust structure of fully automatic powder product hydraulic press, solves the short problem in service life of plug and connecting rod in the present pulverulent product punching course.
The purpose of the utility model realizes through following technical proposals:
The exhaust structure of fully automatic powder product hydraulic press comprises pedestal, on pedestal, is connected with punch, and described punch is the cylindric of hollow, and pedestal is provided with the steam vent that is communicated with the internal cavities of punch.Pedestal is the part that is connected on the stamping machine, is driven by stamping machine, and pedestal is used to connect punch and stamping machine, and pedestal is cylinder on the whole; Its inside is cylindrical cavity, and punch is a cylindrical shape, and its inside is cavity structure, and a steam vent is set on pedestal; Steam vent is communicated with the internal cavities of punch, and during use, the gas of air compressor machine blows to powder in the die, and stamping machine drives pedestal; Pedestal drives punch and moves downward, punch with powder compaction is become whole after die cooperates, the air between die and the punch is through the steam vent discharge from the pedestal then of the cavity of punch inside; So, can discharge the middle air of powder equally, and; Not be used in and process perforate on the punch, make all punch all can directly be connected on the pedestal, practiced thrift in all operations that all will process opening on the punch that is coated with; Simultaneously, guaranteed the uniformity of punch, made its longer service life.
Between described pedestal and punch, also be provided with protective ring.Further say; Further improvement as the utility model is provided with protective ring between punch and pedestal, protective ring is sleeved on the punch; The punch that causes because of pressure is excessive when preventing the product compacting presses blast back metal disorderly to fly to injure human body everywhere, plays the effect of security protection.
Said protective ring is a plastic bushing.Say that further preferably, adopt plastic bushing as protective ring, plastic bushing is supported by elastoplast, itself has certain elasticity, be sleeved on the punch after, plastic bushing has elasticity, effective compensator or trimmer pressure, the instantaneous pressure that the minimizing punch receives.
The utility model compared with prior art has following advantage and beneficial effect:
The exhaust structure of 1 the utility model fully automatic powder product hydraulic press, air between die and the punch through the inner cavity of punch then the steam vent from the pedestal discharge, so; Can discharge the middle air of powder equally, and, not be used in and process perforate on the punch; Make all punch all can directly be connected on the pedestal, practiced thrift in all operations that all will process opening on the punch that is coated with, simultaneously; Guaranteed the uniformity of punch, made its longer service life;
