Abstract
The utility model discloses a bending mold which comprises a spherical upper mold body and a lower mold body. The lower mold body comprises one-stage bosses and a U-type groove, wherein the one-stage bosses are symmetrically arranged on two sides of the lower mold body, and the U-type groove is formed by the one-stage bosses. The spherical upper mold body is matched with the U-type groove. A polyurethane base plate is further arranged on the lower mold body. Two ends of the polyurethane base plate are arranged on the one-state bosses on two sides of the lower mold body respectively. According to the bending mold, the aims that quality of products is improved and raw materials are saved can be achieved.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of mould for bending.
Background technology
The bending sheet metal is extensively used in mechanical processing process, during the sheet metal bending, uses the Bending Mould operation usually.Existing Bending Mould all is made up of spherical patrix and U-shaped counterdie, sheet material is placed on the U-shaped counterdie, press down by spherical patrix and to make sheet material form certain flexibility, the flexibility of sheet material is by the spherical radius of spherical patrix and common decision of size institute of U-shaped counterdie.
Yet existing Bending Mould, because the impulse force that upper die and lower die are laminated is bigger, tend to make sheet material surface in the bending process that fracture phenomenon takes place, severe patient even the sheet material that can occur breaking split phenomenon, having a strong impact on the quality of product, also is a kind of greatly waste to raw material.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of Bending Mould, improve the quality of products the purpose that saves material to reach.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of Bending Mould, comprise spherical upper die and lower die, described counterdie comprises the one-level boss that bilateral symmetry arranges, with by the formed U-shaped groove of described one-level boss, described spherical patrix and described U-shaped groove match, also be provided with the polyurethane backing plate on the described counterdie, the two ends of described polyurethane backing plate place respectively on the one-level boss of described both sides.
Pass through technique scheme; a kind of Bending Mould disclosed in the utility model is to be provided with the polyurethane backing plate at counterdie, during bending sheet material is placed above the polyurethane backing plate; because the polyurethane backing plate has certain pliability and stretch-resistance; therefore, when spherical patrix carried out the bending action, the polyurethane backing plate of sheet material below had played certain cushioning and protection; make the mild bending of sheet material; prevent from occurring slight crack on the surface, guaranteed product quality, saved raw material.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the schematic diagram of the disclosed a kind of Bending Mould of the utility model embodiment;
Fig. 2 is the work schematic diagram of the disclosed a kind of Bending Mould of the utility model embodiment.
The specific embodiment
The utility model provides a kind of Bending Mould, and as shown in Figure 1, this mould comprises spherical patrix 1 and counterdie 2.The stiff end 11 that is connected with lathe above spherical patrix 1 comprises and the spherical die head 12 of below.Counterdie 2 comprises one-level boss 21 that bilateral symmetry arranges and by the formed U-shaped groove 22 of the one-level boss of both sides, and the link 23 of fixedlying connected with lathe.Spherical die head 12 matches with U-shaped groove 22.Also be provided with polyurethane backing plate 3 on the counterdie, the two ends of polyurethane backing plate 3 place respectively on the one-level boss 21 of both sides.
Bending Mould is when carrying out bending work; work schematic diagram as shown in Figure 2; sheet material 4 is placed polyurethane backing plate top, because the polyurethane backing plate has certain pliability and stretch-resistance, therefore; when spherical patrix carries out the bending action; the polyurethane backing plate of sheet material below has played certain cushioning and protection, makes the mild bending of sheet material, prevents from occurring on the surface slight crack; guarantee product quality, saved raw material.
The above only is preferred embodiment of the present utility model, and in order to limit the utility model, all modifications of making within spirit of the present utility model and equal conversion all should not drop within the protection domain of the present utility model.
