Technical field
This utility model patent relates to a kind of sheet material forming device utilizing polyurethane rubber and solid particle to replace die.
Background technology
Sheet stamping forming is a kind of important Metal Forming technology, industrial technology develops into now, the kind of sheet material forming gets more and more, the new material that a lot of high intensity difficulties shape constantly is used, the shape of product is more complicated, shapes difficulty and strengthens, and the demand of some product is little, therefore, the production of plate stamping product is gradually by producing in enormous quantities to multi items and small lot development.Simultaneously under international big environment, processing manufacturing industry is constantly shortening the product marketization cycle, is reducing effort on the direction of product developing expense, and when utilizing traditional rigid die process for stamping to complex-shaped part forming, shaping difficulty is big, needed for shaping costly, design and the manufacture of mould need again substantial amounts of time and expense, therefore do not meet actual requirement.It addition, the proposition of traditional plate flexible die forming technique, although solve some problems of conventional rigid process for stamping, but suffer from some defects that cannot overcome at present, thus limit the development of such forming technology.In order to solve the problems referred to above and deficiency, therefore this sheet material forming method and technique is proposed.
Summary of the invention
In order to solve the weak point existing for above-mentioned technology, this utility model provides a kind of sheet material forming device utilizing polyurethane rubber and solid particle to replace die.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of sheet material forming device utilizing polyurethane rubber and solid particle to replace die, it is made up of the control system of flexible die forming system, polyurethane rubber;Flexible die forming system is formed by holding frame, support spring, particles supports plate, solid particle, the position control pad of polyurethane rubber, polyurethane rubber, guided mode plate, blank holder and punch;The control system of polyurethane rubber is made up of bracing frame, polyurethane rubber spool, bearing, tinsel, spring, spring anchor block.
Supporting spring and be arranged on appearance frame bottom, particles supports plate is fixed on support spring upper end, and solid particle is positioned on particles supports plate.
The position control pad of polyurethane rubber is arranged on appearance arch;Polyurethane rubber is positioned over the upper surface of the position control pad of polyurethane rubber, and the thickness of polyurethane rubber is 5mm-10mm.
Multilayer polyurethane rubber it is wound with on polyurethane rubber spool;Bracing frame is positioned at appearance frame both sides and is connected with polyurethane rubber spool, and spring anchor block consolidates with bracing frame;Lower spring end is connected with spring anchor block, and spring upper end is connected with wire end, and tinsel top is fixedly arranged on polyurethane rubber spool.
Guided mode plate is arranged on the top of polyurethane rubber, and guided mode plate lower surface exists micro gap with the upper surface of polyurethane rubber.
Sheet material is placed on guided mode plate upper surface;Blank holder is close to the upper surface of sheet material.
This utility model is to utilize to hold to place polyurethane rubber in frame and fill solid particle as power transmission medium, and during punch is descending, sheet material gradually deforms under the forming pressure of punch.Polyurethane rubber is because of by the resistance of spring with support buffer brake that spring and solid particle produce and be close to plate surface, it is to avoid sheet material directly directly contacts with solid particle, improves surface quality and the precision of sheet material forming product.Further, under the effect of reverse compressive stress, the patch mould making sheet material is more preferable, improves the forming limit of sheet material, and the local of effective suppression plate is thinning.
Accompanying drawing explanation
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As Figure 1-Figure 2, this utility model it be made up of the control system of flexible die forming system, polyurethane rubber;Flexible die forming system is formed by holding frame 1, support spring 12, particles supports plate 3, solid particle 11, the position control pad 9 of polyurethane rubber, polyurethane rubber 4, guided mode plate 5, blank holder 8 and punch 7;The control system of polyurethane rubber is made up of bracing frame 2, polyurethane rubber spool 10, bearing 13, tinsel 14, spring 15, spring anchor block 16.
Supporting spring 12 and be arranged on bottom appearance frame 1, particles supports plate 3 is fixed on support spring 12 upper end, and solid particle is positioned on particles supports plate.
The position control pad 9 of polyurethane rubber is arranged on appearance frame 1 top;Polyurethane rubber 4 is positioned over the upper surface of the position control pad 9 of polyurethane rubber, and the thickness of polyurethane rubber 4 is 5mm-10mm.
Multilayer polyurethane rubber 4 it is wound with on polyurethane rubber spool 10;Bracing frame 2 is positioned at appearance frame 1 both sides and is connected with polyurethane rubber spool 10, and spring anchor block 16 consolidates with bracing frame 2;Spring 15 lower end is connected with spring anchor block 16, and spring 15 upper end is connected with tinsel 14 end, and tinsel 14 top is fixedly arranged on polyurethane rubber spool 10.
Guided mode plate 5 is arranged on the top of polyurethane rubber 4, and guided mode plate 5 lower surface exists micro gap with the upper surface of polyurethane rubber 4.
Sheet material 6 is placed on guided mode plate 5 upper surface;Blank holder 8 is close to the upper surface of sheet material 6.
This utility model forming process is as follows:
As it is shown in figure 1, be placed on guided mode plate 5 by sheet material 6, according to forming dimension requirement, adjust the position of the position control pad 9 of blank holder 8, guided mode plate 5, polyurethane rubber respectively.During punch 7 is descending, sheet material 6 gradually deforms under the forming pressure of punch 7, when the polyurethane rubber 4 being wound on polyurethane rubber spool 10 contacts with the sheet material 6 gradually deformed, polyurethane rubber 4 is pulled downwardly out by the effect of power, now polyurethane rubber 4 drives polyurethane rubber spool 10 to rotate, the tinsel 14 that then top is fixedly arranged on polyurethane rubber spool 10 constantly will be wound around along with the rotation of polyurethane rubber spool 10 on axle, and then tinsel 14 will pull up spring 15, make spring 15 anamorphic stretching.Owing to polyurethane rubber 4 has bigger elastic deformation, and sheet material 6 overcomes the resistance of spring 15 during moving downward indirectly, make solid particle 11 flow simultaneously, support spring 12 compression, polyurethane rubber 4 is close to sheet material 6 surface by the buffer brake that then resistance of spring 15 and support spring 12 and solid particle 11 produce, avoid sheet material 6 directly directly to contact with solid particle 11, improve surface quality and the precision of sheet material 6 formed product.Further, under the effect of reverse compressive stress, can improve the forming limit of sheet material 6, the local of effective suppression plate is thinning.
After completing whole forming process, punch 7 is up, separates with sheet material 6, takes formed sheet material 6 away, then polyurethane rubber 4 returns back to initial condition under the effect that the restoring force of spring 15 and natural resiliency shrink again, supports spring 12 and solid particle 11 the most all restores to the original state state.When shaping next time, only need to place sheet material 6 to be processed, repeat above operating procedure.
Above-mentioned embodiment is not to restriction of the present utility model; this utility model is also not limited to the example above; change that those skilled in the art are made in the range of the technical solution of the utility model, retrofit, add or replace, also belong to protection domain of the present utility model.
