Abstract
The utility model discloses a rubber containing frame for a positive bending die, relates to mechanical equipment. The rubber containing frame comprises a fixed seat and a containing frame, wherein the containing frame is arranged on the upper surface of the fixed seat. The containing frame is a hollow barrel body with two open ends, and a rubber die cushion is arranged in a hollow cavity of the containing frame. The upper surface of the rubber die cushion is level with the upper surface of the containing frame, and a detachable annular cushion block is arranged between the rubber die cushion and the inner wall of the containing frame. The upper surface of the containing frame is provided with a guide plate, and the upper surface of the fixed seat is provided with a groove in a position opposite to the rubber die cushion. The width of the groove is smaller than that of the rubber die cushion. The rubber containing frame can be used for replacing the steel die of the traditional bending die, and the precision and the surface quality of bending parts are increased. The die has a simple structure, low manufacture cost and practicality.
Description
Technical field
The utility model relates to a kind of plant equipment, relates in particular to a kind of rubber that is used for the positive curve mould and holds frame.
Background technology
Crooked part is one of punching parts that quantity was maximum during Modern Industry Products, automobile, electrical equipment, instrument and instrument were made.The crooked part major part adopts bending die to process, and existing bending die comprises the punch and the die of steel, and punch is descending under the drive of forcing press; Workpiece is accomplished brake forming under the acting in conjunction of punch and die, for precision and the surface quality that improves crooked part, just must in traditional die, add structures such as top board or bullet apical organ; And improve the precision of punch and die; Make mould structure complicated like this, manufacture difficulty is big, and manufacturing cost is high.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of rubber that is used for the positive curve mould to hold frame, can be used for replacing the steel die of conventional bending mould; The precision and the surface quality of crooked part have been improved; And mould structure is simple, and low cost of manufacture is very practical.
The technical scheme of the utility model is: a kind of rubber that is used for the positive curve mould holds frame; Comprise holder and the appearance frame that is arranged at the holder upper surface, the appearance frame is a both ends open, the cylindrical shell of hollow; Be provided with the rubber die-cushion in the cavity of appearance frame; The upper surface of rubber die-cushion and the flush of holding frame are provided with dismountable annular cushion block between rubber die-cushion and the appearance frame inwall, hold the frame upper surface and are provided with guide plate; The position that the holder upper surface is corresponding with the rubber die-cushion has groove, and the width of groove is less than the width of rubber die-cushion.
As preferably, said rubber die-cushion adopts polyurethane rubber to process.
As preferably, said holder with hold frame and adopt the Q235 steel to process.
As preferably, said annular cushion block is two, is socketed on rubber die-cushion outer surface from inside to outside successively.
The beneficial effect of the utility model is: the utility model can be used for replacing the steel die of conventional bending mould; Can reduce die manufacturing cost significantly, the rubber die-cushion adopts polyurethane rubber to process, and polyurethane rubber is a kind of elastomer; In BENDING PROCESS; Hold in the frame and be in closed state, thereby the rubber die-cushion has liquid static pressure property after stressed, promptly the suffered unit pressure of rubber die-cushion all directions equates.Downward when the descending drive punch of press ram, the rubber die-cushion receives the pressure of punch, forces workpiece to bend along the punch outer peripheral contour.In whole BENDING PROCESS, crooked pressure is even, has reduced resilience, has improved the product precision.And workpiece is in formation state all the time, has improved surface quality of products.Do not need to be provided with in addition top board or play apical organ, also need not carry out fine finishining to punch, mould structure is simple, low cost of manufacture.Very practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of rubber that is used for the positive curve mould holds frame; Comprise holder 5 and the appearance frame 4 that is arranged at holder 5 upper surfaces, holding frame 4 is both ends open, the cylindrical shell of hollow; Be provided with rubber die-cushion 2 in the cavity of appearance frame 4; In the present embodiment, as preferably, said rubber die-cushion 2 adopts polyurethane rubbers to process.The upper surface of rubber die-cushion 2 and the flush of holding frame 4; Rubber die-cushion 2 and hold between frame 4 inwalls and be provided with dismountable annular cushion block 3, in the present embodiment, as preferably; Said annular cushion block 3 is two, is socketed on rubber die-cushion 2 outer surfaces from inside to outside successively.In the actual production, can make the utility model be applicable to the workpiece bending machining of different size through the annular cushion block 3 of changing different size or the quantity of adjusting annular cushion block 3.Hold frame 4 upper surfaces and be provided with guide plate 1, guide plate 1 can be when brake forming plays the effect of guiding to workpiece, guarantees the precision of product.Holder 5 upper surfaces have groove 6 with rubber die-cushion 2 corresponding positions, and the width of groove 6 is less than the width of rubber die-cushion 2.In the present embodiment, as preferably, the cross section of said groove 6 is a rectangle, can certainly be other shapes, and is such as semicircle, trapezoidal etc.Groove 6 can reduce rubber die-cushion 2 surface local compression, prolongs the service life of rubber die-cushion 2.
In the present embodiment, as preferably, said holder 5 with hold frame 4 and adopt the Q235 steel to process its good combination property, long service life.
The above is merely a kind of embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and obvious mode of texturing etc., all should be included within the protection domain of the utility model.
