Abstract
The invention discloses a material return mechanism of a stretching die, and relates to the field of dies, in particular to the material return mechanism of the stretching die. The material return mechanism is simple in structure and convenient to return material, and the cost is reduced. The stretching die comprises an upper die holder, a male die, a female die, a lower die holder and a connecting rod mechanism, wherein the upper die holder, the male die, the female die and the lower die holder are successively arranged from top to bottom; through holes are respectively formed in the center of the upper die holder and the center of the male die; the connecting rod mechanism comprises a connecting rod I, a connecting rod II and a material box tank; one end of the connecting rod I is hinged to the upper die holder, the other end of the connecting rod I is hinged to one end of the connecting rod II, and the other end of the connecting rod II is hinged to the lower die holder; the material box tank is fixedly arranged on the connecting rod II; and the material box tank is obliquely arranged between the male die and the female die. According to the material return mechanism disclosed by the invention, the connecting rod mechanism is additionally arranged, so that the automatic return of materials is realized by utilizing the changes of strokes, and the stretch is not influenced. The material return mechanism disclosed by the invention is convenient to process, low in cost, suitable for small scale production, safe and reliable.
Description
Technical field
The present invention relates to mould applications, more particularly to the unloading mechanism of stretching die.
Background technology
When typical products in mass production makees stretch process, the device structure of needs is complicated, relatively costly.However, for be pilot carry out stretch process when, how efficiently, safety the material returned that product is carried out directly affect the efficiency of processing and the quality of product.In prior art, be pilot is processed by the way of the material returned, the mode for being operated using Traditional Man more.But there is the aspects such as the low, safety of efficiency in manual mode of operation.
The content of the invention
The present invention is directed to problem above, there is provided a kind of simple structure, facilitates the material returned, cost-effective stretching die unloading mechanism.
The technical scheme is that：The stretching die includes successively from top to bottom upper bolster, punch, die and die shoe, and the center of the upper bolster and the center of punch are provided with through hole；Also include linkage, the linkage includes connecting rod one, connecting rod two and magazine groove, and one end of the connecting rod one is hinged on upper bolster, and one end of other end articulated linkage two, the other end of the connecting rod two is hinged on die shoe；
The magazine groove is fixed and is located on the connecting rod two, and the magazine groove is inclined and is located between the punch and die.
It is provided with the through hole and makes bar.
Connection source of the gas in the through hole.
Angle between the connecting rod two and horizontal plane is 15 ° -50 °, and the magazine groove is perpendicular to the connecting rod two.
The present invention increases linkage on the upper and lower die holder of stretching die, automatic material returning is realized using stroke change, during beginning, lower section of the magazine groove in punch, punch is run downwards when being stretched, and magazine groove is run to outside mould, do not affect stretching, when stretching is completed, punch runs up, and magazine groove is run to the lower section of punch, by beating bar dnockout or malleation source of the gas can be passed through, stretching material is pushed in magazine groove, magazine groove band is gradient, material is rolled in semi-finished product box.The convenient processing of the present invention, low cost, it is adaptable to small lot batch manufacture is safe and reliable.
Description of the drawings
Fig. 1 is the structural representation of the first embodiment in the present invention,
Fig. 2 is the working state figure one of the present invention,
Fig. 3 is the working state figure two of the present invention,
Fig. 4 is the structural representation of second embodiment in the present invention；
1 is upper bolster in figure, and 2 is punch, and 3 is die, and 4 is die shoe, and 5 is connecting rod one, and 6 is connecting rod two, and 7 is magazine groove, and 8 is through hole, and 9 is to make bar, and 10 is stretching material.
Specific embodiment
As Figure 1-4, the stretching die includes successively from top to bottom upper bolster 1, punch 2, die 3 and die shoe 4 to the present invention, and the center of the upper bolster 1 and the center of punch 2 are provided with through hole 8；Also include linkage, the linkage includes connecting rod 1, connecting rod 26 and magazine groove 7, and one end of the connecting rod 1 is hinged on upper bolster 1, and one end of other end articulated linkage 26, the other end of the connecting rod 26 is hinged on die shoe 4；In work, it is hinged between connecting rod one, two, meanwhile, connecting rod one, two is respectively hinged on upper bolster and die shoe, the magazine groove action in upper bolster direct action, and then drivening rod two and connecting rod two, it is not necessary to increase power source, simple to operate, reliable.
The magazine groove 7 is fixed and is located on the connecting rod 25, and the magazine groove 7 is inclined and is located between the punch 2 and die 3；As shown in Fig. 2 in stretching so that magazine groove is located at the outside of mould；As shown in figure 3, after stretching so that magazine groove is located at centre, the underface of punch of mould, is easy to splicing, while rolling in the direction of the arrow to the semi-finished product box in outside, it is to avoid safe and reliable by manually carrying out the material returned.
As shown in figure 1, the first embodiment in the present invention is：It is provided with the through hole 8 and makes bar 9；Bar is made in setting, by rigid action, directly stretching material 10 is pushed into magazine groove 7.
As shown in figure 4, second embodiment in the present invention is：Connection source of the gas in the through hole 8, by flexible action, directly pushes magazine groove 7 by stretching material 10.
Angle a between the connecting rod 26 and horizontal plane is 15 ° -50 °, and the magazine groove 7 is perpendicular to the connecting rod 26；By arranging the angle between connecting rod two and horizontal plane so that magazine groove can be securely positioned in the outside of mould in minimum angle, the normal work for stretching is not affected；In maximum angle, the underface of punch can be securely positioned in, improve the accuracy of splicing；Magazine groove perpendicular to connecting rod two, the reliably action of coupler link one, two, meanwhile, be easy to after splicing be discharged to outside, save manpower, adapted to small lot batch manufacture, reduce cost.
The present invention at work, alleviates labor intensity, improves class's yield, strengthens safety.
