Abstract
The invention discloses a combined type rubber containing frame for a large bending die and relates to a die part. The combined type rubber containing frame for the large bending die comprises a fixed base and a containing frame body which is arranged on the upper surface of the fixed base, wherein the containing frame body is a hollow cylinder with the two ends open, a glass fiber-reinforced plastic anti-corrosion coating is arranged on the surface of the containing frame body, rubber die pads are arranged in a cavity of the containing frame body and comprise a polyurethane rubber pad and a natural rubber pad, the natural rubber pad is arranged on the lower portion of the cavity of the containing frame body, the polyurethane rubber pad is arranged on the upper surface of the natural rubber pad, and the upper surface of the polyurethane rubber pad is flush with the upper surface of the containing frame body. The combined type rubber containing frame for the large bending die can be used for replacing a steel female die of a traditional bending die, part bending accuracy is improved, the surface quality of a bent part is improved, and the die is simple in structure and low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of mold component, relate in particular to a kind of combined rubber for large-scale bending die and hold frame.
Background technology
Crooked part is one of punching parts that during Modern Industry Products, automobile, electrical equipment, instrument and instrument are manufactured, quantity is maximum.Crooked part major part adopts bending die to process, existing bending die comprises punch and the die of steel, punch is descending under the drive of forcing press, workpiece completes brake forming under the acting in conjunction of punch and die, in order to improve precision and the surface quality of crooked part, just must in traditional die, add top board or play the structures such as apical organ, and improve the precision of punch and die, make like this mould structure complicated, manufacture difficulty is large, manufacturing cost is high, particularly for large-scale bool, the die that it is corresponding and the size of punch are larger, fine finishining is more difficult, cost is higher.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of combined rubber for large-scale bending die and hold frame, can be used for replacing the steel die of conventional bending mould, improved precision and the surface quality of crooked part, and mould structure is simple, low cost of manufacture.
Technical scheme of the present invention is: a kind of combined rubber for large-scale bending die holds frame, comprise holder and the appearance frame that is arranged at holder upper surface, appearance frame is the cylindrical shell of both ends open, hollow, hold frame table face and be provided with Corrosion Protection of Fiber Reinforced Plastics layer, in the cavity of appearance frame, be provided with rubber die-cushion, described rubber die-cushion comprises polyurethane rubber pad and natural rubber pad, described natural rubber pad is arranged at the bottom that holds frame cavity, polyurethane rubber pad is arranged at natural rubber pad upper surface, the upper surface of polyurethane rubber pad and the upper surface flush of holding frame.
As preferably, between polyurethane rubber pad and natural rubber pad, be provided with the rod that is shaped, described shaping rod is two, near the inwall that holds frame, is symmetrical set.
As preferably, described appearance frame and holder welding, hold frame outer wall and be provided with ribs, and ribs welds respectively with holding frame and holder, described holder, holds frame and ribs adopts Q235 steel to make.
The invention has the beneficial effects as follows: the present invention can be used for replacing the steel die of conventional bending mould, can reduce significantly die manufacturing cost, rubber die-cushion adopts the combining structure of polyurethane rubber pad and natural rubber pad, further reduced die manufacturing cost, but still kept the feature of polyurethane rubber, in BENDING PROCESS, hold in frame in closed state, thereby rubber die-cushion has liquid static pressure after stressed, the suffered unit pressure of rubber die-cushion all directions equates.Downward when the descending drive punch of press ram, rubber die-cushion is subject to the pressure of punch, forces workpiece to bend along punch outer peripheral contour.In whole BENDING PROCESS, crooked pressure is even, has reduced resilience, has improved Product Precision.And workpiece, all the time in formation state, has improved the surface quality of product.Do not need to arrange in addition top board or play apical organ, also not needing punch to carry out fine finishining, mould structure is simple, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As one embodiment of the present invention, as shown in Figure 1, a kind of combined rubber for large-scale bending die holds frame, comprise holder 6 and the appearance frame 4 that is arranged at holder 6 upper surfaces, holding frame 4 is the cylindrical shell of both ends open, hollow, hold frame 4 surfaces and be provided with Corrosion Protection of Fiber Reinforced Plastics layer, fiberglass is good anticorrosion-rust prevention material, atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are had to good resistivity, extended service life of the present invention, and it only need be at corresponding component external coating fiberglass, and manufacture craft is simple, very convenient.In the cavity of appearance frame 4, be provided with rubber die-cushion, described rubber die-cushion comprises polyurethane rubber pad 3 and natural rubber pad 1, described natural rubber pad 1 is arranged at the bottom that holds frame 4 cavitys, polyurethane rubber pad 3 is arranged at natural rubber pad 1 upper surface, adopt the combination of polyurethane rubber pad 3 and natural rubber pad 1, reduce the manufacturing cost of mould, and still kept the feature of polyurethane rubber.In the present embodiment, as preferably, described natural rubber pad 1 is three layers, and polyurethane rubber pad 3 is two-layer.Certainly its number can be adjusted accordingly according to the size of shaping workpiece and appearance frame 4.Between polyurethane rubber pad 3 and natural rubber pad 1, be provided with the rod 2 that is shaped, described shaping rod 2 is two, is symmetrical set the pressure when rod 2 that is shaped can increase bending near the inwall that holds frame 4.The upper surface of polyurethane rubber pad 3 and the upper surface flush of holding frame 4.
In the present embodiment, as preferably, described appearance frame 4 outer walls are provided with ribs 5, have strengthened intensity of the present invention.Described appearance frame 4 and holder 6 welding, ribs 5 weld respectively with holding frame 4 and holder 6, guarantees, when carrying out large-scale bool crooked, to hold frame 4 and holder 6 and do not produce and relatively move, and has improved quality and the precision of product.As preferably, described holder 6, hold frame 4 and ribs 5 adopts Q235 steel to make, its good combination property, long service life.
