Description
Technical field
The present invention relates to a kind of ejecting mechanism of mould, especially relate to a kind of slidingtype spring punch die ejecting mechanism.
Background technology
At present; often cold-heading technology can be used in machine industry; and the spring punch die in cold-heading technology is widely used; material returned rod is not had as shown in Figure 1 in this spring punch die; and the height L5 of the bottom to alloy punch die bottom forming hole 9 is equal with the total length L 6 of thimble 2, so thimble 2 can not eject workpiece.Adopt spring punch die jumping-up that buckling and folding line defect can not occur, upsetting length can also be increased, and about upsetting length being brought up to 8 times of diameters, but, higher and when having the workpiece of straight section at upsetting head, or this product bar portion is shorter, all can has at spring punch die and cause cannot normally produce containing material phenomenon (being commonly called as band material phenomenon); In order to avoid, containing the appearance of material phenomenon, being all generally forming hole is processed into the forming hole with pattern draft, being made in like this in subsequent handling and will revising product or reprocess, corresponding operation must be increased.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can increase upsetting length and there will not be containing material phenomenon slidingtype spring punch die ejecting mechanism.
The present invention solves the technical scheme that its technical problem takes: a kind of slidingtype spring punch die ejecting mechanism, comprise die sleeve, one side end face of die sleeve is provided with backing plate, in die sleeve, backing plate is provided with spring pad, spring pad is provided with spring, described spring pad comprises bottom big column and top small column, small column is positioned at spring inner, the step surface of big column places spring end face, the top of spring is provided with alloy punch die, alloy punch die is provided with punch die step, die sleeve inside is provided with die sleeve step, punch die step and die sleeve step with the use of, alloy punch die is provided with forming hole, be provided with thimble in the forming hole inside, inside of alloy punch die and place the centre hole of thimble, centre hole is counter sink, the countersunk head degree of depth of centre hole is consistent with the height of thimble head, material returned rod hole is provided with in the middle of described spring pad, material returned rod is provided with material returned rod in hole, backing plate inside below material returned rod hole is provided with excellent hole, top, push up in excellent hole and be provided with top rod.
In order to eject workpiece smoothly, described thimble total length is equal with the height of alloy punch die.
In order to when matched moulds, can the top end face of thimble just bottom forming hole, described material returned rod hole is counter sink, and the difference of the height of its countersunk head and the height of material returned club head is equal with the height of forming hole.
The invention has the beneficial effects as follows: after have employed said structure, all advantages of spring punch die can be retained, and because have employed the shortcoming containing material that material returned bar structure solves spring punch die, subsequent correction or rework process is there will not be without pattern draft, can to reduce the number of rejects and seconds rate, to improve the quality of product and the speed of production of product.

Detailed description of the invention
As Fig. 2, a kind of slidingtype spring punch die ejecting mechanism shown in Fig. 6 and Fig. 7, comprise die sleeve 3, one side end face of die sleeve 3 is provided with backing plate 8, in die sleeve 3, backing plate 8 is provided with spring pad 6, spring pad 6 is provided with spring 4, described spring pad 6 comprises bottom big column 6-2 and top small column 6-1, it is inner that small column 6-1 is positioned at spring 4, the spring pad step surface 14 that big column 6-2 and small column 6-1 is formed places spring end face, the top of spring 4 is provided with alloy punch die 1, alloy punch die 1 is provided with punch die step, die sleeve 3 inside is provided with die sleeve step, punch die step and die sleeve step with the use of, alloy punch die 1 is provided with forming hole 9, be provided with thimble 2 in inside forming hole 9 inside of alloy punch die 1 and place the centre hole 16 of thimble 2, centre hole 16 is counter sink, countersunk head 12 degree of depth of centre hole 16 is consistent with the height of thimble 2 head, material returned rod hole 10 is provided with in the middle of described spring pad 6, material returned rod is provided with material returned rod 5 in hole 10, backing plate 8 inside below material returned rod hole 10 is provided with excellent hole, top, push up in excellent hole and be provided with top rod 11, described material returned rod hole 10 is counter sink, described thimble 2 total length is equal with the height of alloy punch die 1, described material returned rod hole 10 is counter sink, and the difference of the height of the height of its countersunk head 13 and material returned rod 5 heads is equal with the height of forming hole 9.
As shown in Figure 3, clip is feed collet between main mould 7 and spring punch die, and main mould 7 is motionless, and spring punch die moves to main mould 7 direction, and material enters in main mould 7 and forming hole 9, and clip is decontroled, and expects thimble 2 toward pusher simultaneously.As shown in Figure 4, equipment punch die support drives backing plate 8 and die sleeve 3 to move to main mould 7 direction, drive spring pad 6 and material returned rod 5 to move to main mould 7 direction simultaneously, along with spring 4 is compressed, material returned rod 5 is shifted onto when propping up with the cephalic par of thimble 2 and is continued to push away, and shifts thimble 2 onto and stops to during the bottom of forming hole 9.As shown in Figure 5, equipment punch die supporting band dynamic model cover 3 and backing plate 8 move away from main mould 7 direction, simultaneously spring 4 recovers shape and pushes away spring pad 6 toward away from the motion of main mould 7 direction, when step in die sleeve 3 drive with the punch die step 15 of alloy punch die 1 props up time together with alloy punch die 1 away from, stick pusher ejection rod 11 on equipment punch die, top rod 11 pushes away again material returned rod 5, material returned rod 5 is ejection pin 2 again, stop motion when the step of the head step of thimble 2 and the countersunk head 12 of alloy punch die props up time, complete ejecting of material, solve spring punch die away from band material phenomenon during main mould 7.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
