Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.
As shown in Figure 1, Figure 2, it is described in the utility model to be used to produce the continuous of the circular bushing of automobile shown in Fig. 5 and Fig. 6
Mould, including upper mould 1 and lower mould 2, the surface of the upper mould 1 are provided with section 3 and a pair of outer sections 4 in a pair, and interior section 3 is in circle
The angle of arcuation and circular arc is 110 °~120 °, and outer section 4 is also 110 °~120 °, interior section in arc-shaped and the angle of circular arc
4 external diameters are 1.5d, and the outer external diameter of section 4 is that the midpoint line of section 3 and the midpoint line of two outer sections 4 are perpendicular in 1.7d, two,
Lower mould 2 is provided with an interior cut hole 5 being engaged with 3 external diameters of interior section and an outer cut hole being engaged with 4 external diameters of outer section
6, wherein d are the circular chassis diameter of bushing 7 of automobile.Automobile is as shown in Figure 4 with the circular structure of bushing 7.It is located at inscribe on upper mould 1
The rear of piece 3 and outer section 4 is also disposed with pressure head 17, at least two integer head for bed material subsequently to be extruded to convex closure 16
18th, it is provided with punching head 19, counter-bore head 20 and blanking first 21, lower mould 2 and pressure head 17, integer first 18, punching head 19, counter-bore head
20 and blanking it is first 21 coordinate groove 22.
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 local process of work of the present utility model is：As shown in Figure 1, Figure 2 and Figure 7, for producing automobile circle lining
The material strip 12 of set 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, two drifts 8
Material strip 12 is carried out to rush positioning hole 11, after being over, material strip 12 moves right the positioning hole 11 before causing positioned at close to drift 8
Alignment pin 9 immediately below, 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
Put, drift 8 processes second pair of positioning hole 9.As shown in figure 3, two arc holes are gone out in interior section 3 during pushing, first
13, because 3 sections of interior section are in a rectangular trapezoid, so as interior section 3 continues to push, the inner side edge of arc hole 13 can be turned under
The two straight flanges separation in Qu Bingyu arcs hole 13, material is thus formed an inner curve, after machining, above carries on mould 1, so
After continue material conveying band 12 to the right, after the positioning holes 11 processed before four are located at four lower sections of alignment pins 9, push mould
1, drift 8 continues to rush positioning hole 11 to material strip 12, and outside that panel region progress for having processed arc hole 13 of cutting into slices outside 4 pairs
Arcuate socket 14 is processed and forms outer curvature, and the formation of outer curvature is identical with the forming process of inner curve, and interior section 3 is then
Continue processing and form inner curve.The intermediate zone 15 for subsequently needing to pull is formed between arc hole 13 and outer arcuate hole 14.
As shown in figures 3 and 8, a kind of method for producing the circular bushing of automobile, is comprised the following steps that,
(1) positioning hole is rushed：Positioning hole 11 is rushed on material strip 12 using drift 8, the effect of positioning hole 11 is correcting material strip 12
Trend, reduce the feeding error of material strip 12, be conducive to production stable.
(2) puncture：Arc hole 13 is processed on material strip using inner cutter 3.
(3) puncture：Outer arcuate hole 14 is processed on material strip using outer cut 4.(1) detailed process of (2) (3) is with reference to it
Preceding introduction.
(4) convex closure is stretched：The center of arc hole 13 is directed at using pressure head 17 and convex closure 16 is extruded, and convex closure 16 is in now round platform
Shape, the height of convex closure 16 is higher than height of the automobile with the circular convex closure of bushing 7, and the upper surface diameter of convex closure 16 is less than automobile with circular bushing
The external diameter of 7 convex closures, the lower surface diameter of the round platform of convex closure 16 is more than external diameter of the automobile with the circular convex closure of bushing 7.
(5) integer：Integer is carried out using the first 18 pairs of convex closures 16 of integer, the height of convex closure 16 is specially gradually reduced, expands convex
16 upper surface diameters are wrapped, the round platform lower surface diameter of convex closure 16 is shunk, until convex closure 16 becomes cylindric, and convex closure 16 is highly lower slightly
In the convex closure height of the circular bushing 7 of automobile, the body diameter lower surface diameter of convex closure 16 is slightly less than the circular convex closure of bushing 7 of automobile
External diameter.
(6) punching：Using punching head 19 by the top punching of convex closure 16, the diameter of punching head 19 is slightly less than convex closure 16 in (5)
Internal diameter.So go out after circular hole, can be produced on the inner surface of convex closure 16 it is jagged on step, step, can be with following process
Step and burr pressure are fallen by reaming, it is ensured that the wall thickness and intensity of convex closure 16.Because the upper surface of convex closure 16 and the company of side
The thickness for meeting place is relatively small, if the diameter of punching head 19 is equal to the internal diameter of convex closure 16, then would not be formed at the top of convex closure 16
Step, and burr can be only formed, accordingly even when eliminated burr using reaming, but the wall thickness on the side top of convex closure 16 can not
Change, i.e., still very thin, this will reduce the performance of the circular bushing 7 of automobile.
(7) reaming：Stretched into using counter-bore head 20 in convex closure 16, the internal diameter of convex closure 16 is extended to technological requirement and burr
Eliminate, and adjust the height of convex closure 16 to technological requirement.
(8) blanking：The circular bushing punching 7 of the automobile of technological requirement size is got off using blanking first 21.
The utility model has the advantages that：Using the progressive die, along with by reasonably setting the straight of outer cut and inner cutter
Footpath and position relationship each other, by the material strip size reduction produced used in the circular bushing of automobile and can ensure whole
Material during individual punching press between outer cut and inner cutter is not broken in drawing process, while the flowing of material is smooth.
