Abstract

The utility model discloses a deep hole extrusion die, including last membrane module, the extrusion upper punch, floating concave mold, the floating concave mold cover, lower membrane module, bottom knockout pole and nitrogen spring, floating concave mold and floating concave mold cover rigid coupling, the floating concave mold cover can slide from top to bottom under the restriction of direction circle, the bottom knockout pole is vertical, and to stretch into down the lower mold core of membrane module up downthehole, lower membrane module is disposed under the floating concave mold, the membrane module was evenly fixed and is set up in the direction is enclosed under nitrogen spring centered on, the extrusion upper punch is vertical to be fixed at the downward overhang in the bottom of last membrane module and to the blank backward extrusion of setting in floating concave mold under the press effect. Adopt this deep hole extrusion die carry on the cold forging when crowded the aperture extrusion degree of depth be 2.5 of aperture 5 doubly.

Description

Deep extrusion mould
Technical field
The utility model belongs to forging and molding technical field, relates to extrusion die.
Background technology
At present in cold forging part process, it is often necessary to extrude a deep hole on cold forging part.Some parts If the various pins on piston pin, track pin, automobile chassis are all common deep extrusion parts;Also have one A little part such as vehicle transmission sleeve pipe, fork-shaped sleeve pipe and the dehydrating shafts etc. of washing machine, the deep hole in part is to make For preform, extrude that spline, step be ring-type or tubular member the most again.
Deep extrusion is the difficult problem being difficult in cold extruding technique avoid, general hole extruding time, hole depth Control below 2.5 with the ratio of bore dia.The aperture extruding degree of depth is to use conventional finish forge to become during 3-5 times of aperture Shape technology manufacturing process is difficult to, and uses traditional Cutting Process to produce, the letter of machine cut processing technology Single, easily realize producing, due to entirely machining, efficiency is low, and cost is high, and uniformity is poor, produces all Phase is long, wastes material, and secondly integral product intensity is same as strength of parent, and traditional Cutting Process is manufactured Interiors of products tissue looseness, intensity is low, and quality is unstable, and due to material metal streamline cut-off and Comprehensive mechanical performance is made to reduce.
Summary of the invention
The utility model is for the deficiencies in the prior art, it is provided that a kind of deep extrusion mould, the aperture extruding degree of depth 3-5 times of aperture can be reached, overcome the defect that traditional cutting technology produces, use forging and molding technology to improve Product quality comprehensive mechanical performance.
The utility model is achieved by the following technical solution:
Deep extrusion mould, including upper die component, extruding upper punch, floating cavity die, floating cavity die set, under Membrane module, bottom knockout bar and nitrogen spring, floating cavity die is affixed with floating cavity die set, and floating cavity die is enclosed within leads Can slide up and down under the restriction of circle, bottom knockout bar stretches in the lower mold core bore of lower mold assemblies the most upward, under Membrane module is arranged on the lower section of floating cavity die, and nitrogen spring is uniformly and fixedly arranged at guide collar around lower mold assemblies In, extruding upper punch is vertically fixed on the bottom of upper die component and overhangs downwards and to being arranged under press effect Blank backward extrusion in floating cavity die.
The inwall of described guide collar is provided with the upright guide rail matched with floating cavity die set outer wall.
The aperture extruding degree of depth is 2.5-5 times of aperture.
The aperture extruding degree of depth is 4 times of aperture.
The utility model compared with prior art has the advantages that
The utility model overcomes the extruding degree of depth that in prior art, conventional finish forge technology is difficult to break through and can not be more than The technical problem that aperture is 2.5 times, uses the utility model to solve thin-walled aperture by deep hole cold forging extrusion method little And the technical problem of hole depth part precision forging processing difficulties, the aperture extruding degree of depth can reach the 3-5 in aperture Times, the metal streamline of material is not cut off, and through the product that cold forging squeezes, comprehensive mechanical performance improves, product Can be good, steady quality, and also the precision of product can be guaranteed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Sequence number in figure: 1, upper die component, 2, extruding upper punch, 3, floating cavity die, 4, floating cavity die set, 5, lower mold assemblies, 6, bottom knockout bar, 7, nitrogen spring, 8, guide collar, 9, lower mold core.
Detailed description of the invention
Below by embodiment and combine accompanying drawing to the technical solution of the utility model make more specifically Bright.
Embodiment: shown in Figure 1, a kind of deep extrusion mould, including upper die component 1, extruding upper punch 2, floating cavity die 3, floating cavity die set 4, lower mold assemblies 5, bottom knockout bar 6 and nitrogen spring 7, float recessed Mould 3 and floating cavity die overlap 4 affixed, and floating cavity die set 4 can slide up and down under the restriction of guide collar 8, leads Inwall to circle 8 is provided with and overlaps the upright guide rail that 4 outer walls match with floating cavity die, and bottom knockout bar 6 is vertical Stretching into upward in lower mold core 9 hole of lower mold assemblies 5, lower mold assemblies 5 is arranged on the lower section of floating cavity die 3, Nitrogen spring 7 is uniformly and fixedly arranged in guide collar 8 around lower mold assemblies 5, and extruding upper punch 2 is vertically solid The bottom being scheduled on upper die component 1 overhangs downwards and to the blank being arranged in floating cavity die 3 under press effect Backward extrusion, using this deep extrusion mould to carry out aperture extruding degree of depth when cold forging squeezes is 2.5-5 times of aperture.
Embodiment, only to facilitate understand the technical solution of the utility model, is not intended that the utility model The restriction of protection domain, every without departing from technical solutions of the utility model perhaps according to of the present utility model Any simple modification, equivalent variations and the modification that above scheme is made by technical spirit, all still falls within this practicality Within the scope of novel protected.
