Description

There is the assembling die of diastrophic forge piece in a kind of turned blank cross section

Technical field

The utility model relates to the assembling die that there is diastrophic forge piece in a kind of turned blank cross section, belongs to metallized metal die forging field.

Background technology

At present, have the production and processing of diastrophic forge piece generally to adopt the open die forging mode for the blank cross section, deformation processing is shaped gradually, and needs to finish press-bending and shaping work at last by the loose tool of different structure; Another kind of forging production technique is to adopt roll milling technology, finish blank section deformation operation, improved section deformation speed than open die forging production like this, and the whole uniformity guarantees easily, but length overall is difficult for guaranteeing, must increase the operation of once cutting away the tailing head, so just problem concentrate on press little curved, press and bend greatly, cut away on four procedures of stub bar and shaping, prior art will be finished this last several procedures, also must finish press-bending, cut-out and shaping work at last by the loose tool of several different structures, therefore, overall manufacturing efficient is all very low.

Brake shoe key is brake system of rail vehicle product one part, there is diastrophic forge piece in a kind of exactly typical blank cross section, its design feature is: length direction each point cross-sectional sizes is all different, and require evenly excessively, form by twice curved (camber has strict demand) on the whole, and the curved curvature of twice differs greatly, and this just gives to forge to process and causes many inconvenience.At present, the production of this forging is exactly the general open die forging mode that adopts, and deformation processing is shaped gradually, but also must need to finish press-bending and shaping work at last by the loose tool of different structure.

Summary of the invention

The purpose of this utility model has the inefficient present situation of diastrophic forge piece overall manufacturing at the blank cross section just, finish at last particularly that press-bending, cut-out and trimming are loaded down with trivial details, quality state can not guarantee consistent problem, provide a kind of turned blank cross section that the assembling die of diastrophic forge piece is arranged, this assembling die is by roll milling technology, to the band tapering after the rolling and state inconsistent in the middle of blank realize the processing and the cut-out of the workpiece of asymmetric and the completely different requirement of flexibility, once-forming.

The purpose of this utility model is achieved through the following technical solutions:

The utility model comprises patrix, movable upper die and lower die, it is characterized in that: be provided with on the top of patrix with forging equipment the structure that is installed that is connected is installed, two side lower parts at patrix are provided with lead, the lower surface of patrix is the plane, on the lower surface of patrix, be provided with at least four screw hole symmetrically, be provided with cutting edge in the lower end of a lead of patrix; The upper surface of movable patrix is the plane, on movable patrix, be provided with screw hole with the corresponding fully vertical perforation activity patrix of the screw hole of patrix, and the epimere aperture of screw hole and shank of screw coupling, the hypomere aperture of screw hole and head of screw coupling, be provided with the gathering sill that is complementary with the patrix lead in the both sides of movable patrix, the lower surface of movable patrix is the formpiston structure; Movable patrix is connected by screw with patrix, and the gathering sill of the lead of patrix and movable patrix formation leads lock construction, on the shank of screw between movable patrix and the patrix spring is housed; Bottom at counterdie is provided with base plate, and the upper surface of counterdie is provided with the cutting edge that matches with the cutting edge of patrix lead for the female mould structure that the lower surface with movable patrix is complementary on the upper surface of counterdie.

The utility model has the advantages that: for will diastrophic forge piece being arranged with time heating of three fire, three kinds of moulds of utilization, the blank cross section that just can finish processing through four procedures originally, only with once shaping once overlapping assembling die.Make the production efficiency of this forging improve 3-4 doubly, changed and hammered the production model that goes up handwork in the past into shape than prior art; Demonstrate fully and realized to forge high efficiency production advantage; The change of matter has taken place in the product quality state, makes originally every the product that has nothing in common with each other through multiple operation production size and precision become in full accord; Adopting this assembling die to produce forge piece on crank press, is 6% of original steam flat-die hammer multiple operation production energy expenditure; Simultaneously the workman is freed from onerous toil.

The specific embodiment

Embodiment:

Have the processing mold and the process of diastrophic forge piece " brake shoe key " that the utility model is further described with a kind of typical blank cross section below:

With reference to accompanying drawing, the utility model comprises patrix 2, movable patrix 3, counterdie 4, be provided with on the top of patrix 2 with forging equipment the dovetail type that the is connected structure 11 that is installed is installed, two upper lateral parts at patrix 2 are provided with mould hole for hoist 12, two side lower parts at patrix 2 are provided with lead 8, the lower surface of patrix 2 is the plane, on the lower surface of patrix 2, be provided with six screw holes 7 symmetrically, lower end at the left lead of patrix 2 is provided with cutting edge 9, is provided with the cambered surface 10 of workpiece being carried out pressure head in the lower end of the right left lead of patrix 2; The upper surface of movable patrix 3 is the plane, on movable patrix 3, be provided with screw hole 13 with the corresponding fully vertical perforation activity patrix of the screw hole 7 of patrix, and the epimere aperture of screw hole 13 and shank of screw coupling, the hypomere aperture of screw hole 13 and head of screw coupling, be provided with the gathering sill 14 that is complementary with patrix lead 8 in the both sides of movable patrix 3, the lower surface of movable patrix 3 is formpiston structure (its shape designs according to the required shape of forging products); Movable patrix 3 is connected by screw 5 with patrix 2, and the lead 8 of patrix constitutes with the gathering sill of movable patrix 14 leads lock construction, on the shank of screw between movable patrix 3 and the patrix 2, spring 6 is housed, makes the flexible connection that is connected between movable patrix 3 and the patrix 2; Be provided with base plate 16 in the bottom of counterdie 4, the upper surface of counterdie 4 is provided with the cutting edge 15 that matches with the cutting edge 9 of patrix lead for the female mould structure (its shape designs according to the required shape of forging products) that the lower surface with movable patrix 3 is complementary on the upper surface of counterdie 4.
