Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, the mould described in the utility model for being used to produce the circular bushing of automobile, including upper mould 1
With lower mould 2, the surface of the upper mould 1 is provided with a pair of interior sections 3 and a pair of outer sections 4, and interior section 3 is in arc-shaped and circular arc
Angle is 110 °~120 °, and outer section 4 is also 110 °~120 ° in arc-shaped and the angle of circular arc, and 4 external diameters of interior section are 1.5d,
4 external diameters of outer section are that the midpoint line of section 3 and the midpoint line of two outer sections 4 are perpendicular in 1.7d, two, and lower mould 2 is provided with
One is vapour with the interior cut hole 5 that is engaged of 3 external diameters of interior section and an outer cut hole 6 being engaged with 4 external diameters of outer section, wherein d
The automobile-used chassis diameter of circular bushing 7.Automobile is as shown in Figure 4 with the circular structure of bushing 7.
For the accurate positioning of material strip in process for producing the circular bushing of automobile, the interior section 3
Side is provided with two drifts 8, and the line and automobile of two drifts 8 are perpendicular with the conveying direction of material strip used in circular bushing, outside
Uniform four alignment pins 9 of surrounding of section 4, four drift 8 of alignment pin 9 and two one rectangles of formation and two drifts 8 and close two
Two alignment pins 9 of drift 8 constitute and are provided with the pilot hole being engaged with drift 8 and alignment pin 9 on a square, lower mould 2
10, drift 8 is equal with the diameter of alignment pin 9.
The head of the alignment pin 9 is in coniform, accordingly even when during actual processing, material strip has skew somewhat,
It can also be corrected in the presence of the head of alignment pin 9.
In order to ensure during following process, the flowing of material is more smooth, the circle of the interior section 3 and outer section 4
Arc angle is 115 °.
The section of the interior section 3 and outer section 4 is in a rectangular trapezoid, and the straight waist of right-angled trapezium is located at outside respectively.Profit
With right-angled trapezium, bending section is processed so that material will not cause material stiff during involving because of hard draw, i.e., not
Hard pull can be produced and cause the material between interior section 3 and the arc hole and outer arcuate hole of the outer generation of section 4 to split.It is described straight
The trapezoidal specific size in angle is preferably upper bottom 2mm, is gone to the bottom as 4mm, a height of 7mm.
The course of work of the present utility model is：As shown in Figure 1, Figure 2 and Figure 3, for producing the material of the circular bushing of automobile
Band 12 is conveyed to the right from left side, and material strip 12 first reaches the left side of interior cut hole 5 of lower mould 2, and then upper mould 1 is pushed, and two drifts 8 are to material strip
12 carry out rushing positioning hole 11, after being over, and material strip 12 moves right the positioning hole 11 before causing positioned at the positioning close to drift 8
Immediately below pin 9, upper mould 1 is pushed afterwards, and alignment pin 9 passes through the position of the positioning hole 11 processed before and corrective addition band 12, drift 8
Process second pair of positioning hole 9.As shown in figure 3, two arc holes 13 are gone out in interior section 3 during pushing, first, due to interior
3 sections of cutting into slices are in a rectangular trapezoid, so as interior section 3 continues to push, the inner side edge of arc hole 13 can be bent downwardly and with it is interior
Arcuate socket 13 two straight flanges separation, material is thus formed an inner curve, after machining, above carry on mould 1, then proceed to
Right material conveying band 12, after the positioning hole 11 processed before four is located at four lower sections of alignment pin 9, pushes mould 1, drift 8
Material strip 12 is continued to rush positioning hole 11, and cuts into slices outside 4 pairs and has processed that panel region progress outer arcuate hole in arc hole 13
14 process and form outer curvature, and the formation of outer curvature is identical with the forming process of inner curve, and interior section 3 then continues to add
Work formation inner curve.The intermediate zone 15 for subsequently needing to pull is formed between arc hole 13 and outer arcuate hole 14.This practicality is new
The advantage of type is：Using the progressive die, along with by reasonably setting the diameter of outer cut and inner cutter and position each other
Relation is put, the material strip size produced used in the circular bushing of automobile can be reduced and ensure outer during whole punching press
Material between cutting knife and inner cutter is not broken in drawing process, while the flowing of material is smooth.
