Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model discloses a kind of bolt bush assembly parts, and lining and bolt combination that this bolt bush assembly parts is manufactured by cold-heading form, lining and bolt are combined securely, do not come off.
As shown in Fig. 1 to Fig. 2 E, in the utility model, bolt bush assembly parts includes: bolt 300, the lining shaping by cold-forging steel, and described bolt 300 comprises the bead of bolt head, screw rod and described bolt head and described screw rod transition position; Described lining comprises head, guide cylinder 11, the inner shaft of described lining is upwards provided with deep hole 22 and the minor diameter through hole 23 in first hole 21, guide cylinder 11 successively, bolt 300 penetrates in the described minor diameter through hole 23 of described lining, and be flexibly connected with described lining, described lining be provided with outward punching point extruding minor diameter through hole 23 block described screw rod described in be threaded into the part of described bead.The sphere of activities of described lining is the centre of screw flight and the described bolt head of bolt 300.
Be more preferably, be provided with a groove between described head and guide cylinder 11, described sleeve surface applies U.S. special for a long time, so that surface treatment.The lining of this lining assembly parts is mainly used the machine shaping of cold-heading method, and this bolt bush assembly parts is automobile engine cover fixing bolt, has by the bar portion 10 of cold-heading molding and the inner space connecting.
The step that this bolt bush assembly parts shapes comprises: the workpiece 100 of forward extrusion cylindricality forms head and bar portion, and preferred, workpiece 100 is cylindrical body, is cut into predetermined length and is preset as 9.1mm.Fig. 2 A shows workpiece 100 through the concrete structure after first upsetting, and workpiece 100 be extruded into truncated conical shape, the diameter of the bar portion 10 extruding is greater than the diameter of workpiece 100 heads.In forward extrusion process, material flow direction is consistent with mold movement direction.This step completes in the first station, and the first station comprises that mould has: punch die cushion block, punch die PIN, punch die, the main mould of straight hole, main mould PIN.On cold-heading equipment, manufacture and in the bar course of working that this bolt bush assembly parts uses, should avoid the jumping-up part of part or head to occur slight crack or form burr.
The described head of forward extrusion workpiece forms first hole 21 and deep hole 22, and workpiece 100 processes in the first station, moves to the second station, form coaxial setting described head first hole 21 and away from the deep hole 22 of one end of described head, as shown in Figure 2 B.This step completes in the second station, and the second station comprises that mould has: punch die cushion block, punch die PIN(terminal), pad, main die sleeve pipe, main mould PIN, liftout pole and Flat wire spring after pad, the second main mould after punch die, the main core rod of straight hole, main formwork, the first main mould.Workpiece 100 is in forward extrusion process, and material flow direction is consistent with mold movement direction.
Head described in forward extrusion, forms a guide cylinder 11 in bar portion 10, as shown in Figure 2 C.Workpiece 100 is through the described head of extruding, and bar portion 10 length of sides, form guide cylinder 11.Further, first hole 21 of head is communicated with described deep hole 22 to form a minor diameter through hole 23 described in forward extrusion, as shown in Figure 2 D.Minor diameter through hole 23 is communicated with first holes 21 and away from head one end deep hole 22.Bolt 300 is inserted to workpiece 100 and push described head to form 2 points on head both sides.Before punching point, need first inserting bolt 300, then workpiece 100 is rushed a little, guarantee that bolt 300 does not come off.Due in conventional machining process to after workpiece 100 punching point, then bolt 300 manually to knock in workpiece 100, easily cause bolt 300 to come off, affect engine assembly.Bolt 300 inserts after workpiece 100, the screw thread of bolt 300 is all through minor diameter through hole 23, the bottom of 2 of 100 both sides of workpiece over against minor diameter through hole 23 of extruding, by fixture fixation workpiece 100 positions, expose punching point position, by drift crushing failure at high speed, formed and rushed a little, a restriction bolt 300 that rushes for workpiece 100 departs from workpiece 100.
In sum, the utility model bolt bush assembly parts can adopt multi-station cold-heading equipment to process continuously, a step of each station processing, five stations are processed five described bolt bushes simultaneously, each station can be processed a plurality of bolt bush assembly parties, can solve the problems such as the high and product quality of existing processing cost.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
