Abstract
The utility model relates to the field of pressing moulds, in particular to a pressing mould of isometric pressure for a brake block, which has the technical proposal that male moulds 1, a mould cavity body 2, limit screws 3 and 4, a lower heating plate 5, a backing plate 7, lower backing plates for the male moulds 10, a backing pillar for the male mould 11 and a compression spring 12. A plurality of male moulds 1 are corresponding to the lower backing plates for the male moulds 10 and the backing pillar for the male mould 11 and are respectively arranged on the mould cavity body 2 and the lower heating plate 5; the pressing mould of isometric pressure for a brake block has the improvement that a floating cylinder assembly 6 is additionally arranged between each lower backing plate for the male moulds 10 and the backing plate 7, and all the floating cylinder assemblies 6 are communicated through a hydraulic tube. Based on the original equipment, the pressing mould of isometric pressure for a brake block is additionally provided with a floating cylinder assembly to automatically adjust the pressure in each cavity through the flow of oil inside the hydrocylinder in the pressing stage of a pressing plate, thereby achieving the goal of adjusting the thickness of friction materials and the same density.
Description
Technical field
The utility model relates to the compacting tool set field, specifically is specific pressure compacting tool sets such as a kind of brake block.
Background technology
The drawing method of brake block generally has two kinds, cold moudling and hot forming at present.Along with the maturation day by day of production technology, one-shaping technique is more and more accepted by people with its unique advantage.Adopt one-shaping technique, once can be pressed the production efficiency height a plurality of die cavitys.Because phenomenons such as cavity dimension error, weighing error.In pressing process, each chamber can be different to the pressure of friction material, can cause different die cavitys to suppress different mill material density, thereby cause the brake block performance different.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of multimode cavity once molded on year-on-year basis etc. the specific pressure compacting tool set.
Its technical scheme is: comprise punch 1, die cavity body 2, stop screw 3 and 4, following heating plate 5, backing plate 7, punch lower bolster 10, punch pad post 11, compression spring 12, a plurality of punch 1 form corresponding with punch lower bolster 10, punch pad post 11, and be separately positioned on die cavity body 2 and the play heating plate 5, its improvement is: increase unsteady cylinder assembly 6 between each punch lower bolster 10 and backing plate 7, all unsteady cylinder assemblies 6 connect mutually by hydraulic oil pipe.
Such scheme also comprises: all be connected with asbestos pad 9 by fillister head screw 8 between each unsteady cylinder assembly 6 and punch lower bolster 10.On die cavity body 2 and following heating plate 5, heater is set.Heater comprises and running through in vivo or external circulation pipe or torus.
The utility model is on the basis of existing equipment, and design increases the cylinder assembly that floats, and makes the pressing plate depression phases, can adjust each cavity pressure automatically by flowing of oil in the oil cylinder, thereby reach the purpose of adjusting friction material thickness and equal densities.
Description of drawings:
Fig. 1 is the cutaway view of the novel main TV structure of this use.
The specific embodiment:
With reference to accompanying drawing, existing brake block compacting tool set comprises: punch 1, die cavity body 2, stop screw 3 and 4, following heating plate 5, backing plate 7, punch lower bolster 10, punch pad post 11, compression spring 12, a plurality of punch 1 and punch lower bolster 10, punch pad post 11 form corresponding, and are separately positioned on die cavity body 2 and the following heating plate 5.This use is novel from adjusting the pressure dependence of each punch and punch lower bolster, and utilizing increases the cylinder assembly 6 that floats between each punch lower bolster 10 and backing plate 7, and all unsteady cylinder assemblies 6 connect mutually by hydraulic oil pipe.After adding material in the cavity body of mould, mould is inserted in the forcing press, forcing press is exerted pressure, mould can this operating mode of self adaptation, guarantee effect is identical at the pressure of each pressed blocks lining, no matter whether the filler that reason such as cavity dimension error, weighing error causes in each die cavity is identical like this, can both guarantee that its pressure is identical, just realized that also density is identical, guaranteed that the brake block performance is identical.
Also comprise in the above-mentioned example: between each unsteady cylinder assembly 6 and punch lower bolster 10, all be connected with asbestos pad 9, its protection and buffering effect by fillister head screw 8.On die cavity body 2 and following heating plate 5 heater is set, heater is the circulation pipe that is applied in the cavity, uses with the compacting of satisfying under the pressurized conditions.
