Abstract
The utility model provides a drawing structure one-step forming device, comprising two parts of an upper die and a lower die. The drawing structure one-step forming device is characterized in that the upper die consists of an upper die holder, an unloading plate, an air valve and a punch; the upper die holder is arranged on the upper surface of the unloading plate; the distance between the upper die holder and the unloading plate can be adjusted by the air valve; the punch is fixed with the lower end of the upper die holder; the unloading plate is provided with a through hole which is matched with the punch; the lower die comprises a concave die; a die cavity of the concave die is internally provided with an internal top which is corresponding to the punch; the internal top can longitudinally move in the die cavity; the lower end of the internal top is connected with a force transmission plate; the lower end of the force transmission plate is connected with a telescopic shaft of a demoulding cylinder. The drawing structure one-step forming device can stretch the material by one-step forming and the product has good quality.
Description
Technical field
The utility model relates to a kind of die device, particularly a kind of pull and stretch structure one step shaping apparatus.
Background technology
On some handware products, often have the product structure that some need pull and stretch; common way is by the several operations position in the exploitation several engineering mould or the progressive die material to be changed length by length, makes the material projection reach the requirement of product structure at leisure.But, use this die device, not only the production cost height, operation is many, production is complicated and be difficult for to guarantee product quality, it is wrinkling to be broken in product projection position, projection position size accuracy is poor.
Summary of the invention
The purpose of this utility model provides a kind of pull and stretch structure one step shaping apparatus that can effectively overcome the problems referred to above generation, and by this device material is carried out pull and stretch and can finish by once-forming, and the quality better of product.
The purpose of the utility model structure is achieved in that it comprises upper die and lower die two parts, its improvement is, patrix is formed by upper bolster, stripper, air valve with towards public four parts, upper bolster is positioned at above the stripper, distance between them can be adjusted by air valve, dash public affairs and fix with the upper bolster lower end, stripper is provided with and dashes the public through hole that cooperates; Counterdie comprises die, is provided with in the die die cavity and pushes up in public corresponding, and interior top can vertically move in die cavity, and the Nei Ding lower end is connected with force transmitting board, and the force transmitting board lower end is connected with the telescopic shaft of demoulding cylinder;
In the said structure, air valve and upper bolster are fixed, and stretch out a telescopic shaft from the air valve lower end, and telescopic shaft and stripper are fixed by screw;
In the said structure, towards public bottom operate portions diameter than the big 0.1-0.4mm of waist diameter.
In sum, the utility model pull and stretch structure one step shaping apparatus adopts said structure, air valve and demoulding cylinder produce powerful pressure-plate-force, make the material between the upper die and lower die dash under the public pressure, slowly to lower convexity, and then form the high protruding pull and stretch shape that needs on the product along the die cavity of die.Adopting this device that material is carried out pull and stretch can finish by once-forming, and in the process of pull and stretch, material can evenly flow along the space that dashes between public and the die die cavity, has so also ensured the quality of product.
Description of drawings
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is the structural representation of pull and stretch structure one step shaping apparatus die opening state
Fig. 2 is the structural representation of pull and stretch structure one step shaping apparatus mold closing state
The specific embodiment
As shown in Figure 1, the utility model pull and stretch structure one step shaping apparatus comprises patrix 1 and counterdie 2, patrix comprises upper bolster 3, stripper 4, air valve 5 and dash public 6, upper bolster 3 is positioned at above the stripper 4, air valve 5 is fixing with upper bolster 3, stretch out a telescopic shaft 12 from the air valve lower end, telescopic shaft 12 is fixing by screw 13 with stripper 4, dashing public affairs 6 fixes with upper bolster 3 lower ends, stripper 4 is provided with and dashes the public through hole that cooperates, and when in the telescopic shaft 12 indentation air valves 5, it is close to stripper that air valve can drive upper bolster, distance between stripper and the upper bolster can reduce, dash public just can by through hole protrude from stripper below; Counterdie 2 comprises die 7, interior top 8, force transmitting board 9 and demoulding cylinder 10, die 7 is provided with and dashes public 6 die cavitys that cooperate, interior top 8 is positioned in the die cavity of die 7,8 lower ends, interior top are connected with force transmitting board 9, in withstand under the effect of dashing public and force transmitting board and can in die cavity, vertically move, the force transmitting board lower end is connected with the telescopic shaft 14 of demoulding cylinder 10, and the consumption of demoulding cylinder 10 can produce powerful active force.
As shown in Figure 2, material 11 fixing between the upper die and lower die is carried out pull and stretch add man-hour, when in the telescopic shaft 12 indentation air valves of air valve 5, it is close to stripper that air valve can drive upper bolster, distance between stripper 4 and the upper bolster 3 can reduce, dash public 6 just can by through hole protrude from stripper below, distance between stripper 4 and upper bolster 3 further reduces, heading on material towards the open beginning pours downwards in the die cavity of die, interior top in the die cavity also upwards heads on material simultaneously, interior top 8, material 11 is with dashing public 6 to descending, the telescopic shaft 14 of demoulding cylinder also can retraction demoulding cylinder in, in this course, material is under the common pressure that dashes public and interior top, along the die cavity of die slowly to lower convexity, and by adjusting air valve and demoulding cylinder, the pressure of public affairs 6 and the 8 pairs of materials 11 in interior top is dashed in control, material is evenly flowed along the space that dashes between public and the die die cavity, and then formed the high protruding pull and stretch shape that needs on the product.
As shown in Figure 2, bottom operate portions 602 diameters that dash public affairs 6 are than the big 0.15mm of waist 601 diameters, such structural design makes dashes the public active force that can bear very large from following moulding/demoulding cylinder generation, also make simultaneously and dash public affairs in the course of work material, distribute the heat that material produces because of distortion rapidly and reduce the material public friction that liquidates, make towards public affairs can be not easily not tiredly and damage, also make material evenly mobile, guaranteed quality along the space that dashes between public and the die die cavity.
After pull and stretch is finished, the telescopic shaft 14 of demoulding cylinder 10 begins to stretch out, interior top up promotes together with patrix, material begins to deviate from the die die cavity, and when material was deviate from the die die cavity fully, the air valve 5 of patrix began inflation work, telescopic shaft 12 stretches out air valve, air valve drives upper bolster away from stripper, and the distance between stripper and the upper bolster can increase, and impels stripper to promote the material disengaging downwards and dashes public.
