The lower mold comprises two lower mold housings and a lower mold body as well as first and second surface molds, wherein a downward groove is formed in the upper surface of the lower mold body; the two lower mold housings are arranged at the two ends of the lower mold body respectively; two bearings are axially arranged on the lower mold housings; the first and second surface molds are parallel to each other and are symmetric in shape. According to the special lower mold, the computer case is bent by the aid of cooperative turnover of the first and second surface molds; the contact between a workpiece and the lower mold is changed into current surface contact from linear contact between the workpiece and an old mold, so that the surface of the workpiece cannot be damaged; the computer case can be bent in one time, a fold mark is a straight line, the precision is high, the operation is convenient, and the cost is low; the processed surface molds are good in hardness, high in strength and planarity and hard to deform.
Description
Technical field
The invention belongs to Design of Dies field, specifically, relate to a kind of bending machine die, more particularly, relate to a kind of special bed die of computer housing bending.
Background technology
Bending machine die is that bender is used for the instrument of machine-shaping plate, and this instrument consists of various parts, the part difference that different moulds forms.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.Under the effect of bender pressure, by the guiding each other of upper die of bending machine and counterdie, blank is become and have the workpiece of given shape and size.In actual production process, enterprise can, according to the difference of shaping workpiece shape or size, configure the counterdie of different groove angles.But along with expanding economy, the shape of the workpiece of the bending of wanting is also more and more diversified, different like this workpiece just needs special mould to process, for example, in man-hour that adds of computer housing, require comparatively strict, especially requiring can not have damage to sheet material, and bending part should be absolute straight line, and general bender all can have damage by sheet material.When existing bender carries out bending, be all by mould, to offer " V " type groove or " U " type groove or other shapes to complete bending, when bending operation, sheet material is that line contacts with mould like this, must cause the damage of sheet material.
For example: China Patent No.: 201110389823.4 applyings date: on November 30th, 2011, the patent application document that a name is called a kind of Bending Mould is disclosed, it comprises the V-shaped punch for machining sheet, with with the die of punch adaptation, the contact both sides face of described die is the curved surface that makes to form between described sheet material and die non-sliding friction in process, and the contact both sides face of described die is involute shape curved surface.This beneficial effect of the invention is: improved traditional V-type Bending Mould, can tackle the bending and forming of the sheet material of multi-thickness and flanging width.Improve the production efficiency of bending and forming, reduced the work working strength of frequent replacing Bending Mould.Meanwhile, due to the minimizing of the supporting Bending Mould specification of bender, also further compressed purchasing and maintenance cost of equipment.
For example: China Patent No.: 201110304207.4, the applying date: on October 10th, 2011, disclose a name and be called a kind of bend punching die, related to the diel used of a kind of machining.It comprises upper bolster, train wheel bridge, lower bolster, die shoe, described upper bolster is connected with train wheel bridge, described lower bolster is connected with die shoe, described lower bolster is provided with groove, described train wheel bridge is provided with Bending punch, and described Bending punch is provided with the V-arrangement punching press end matching with lower bolster groove.The above Bending punch top is provided with screw.Its beneficial effect is, adopts after this invention technical scheme, and the punch pin with V-shaped hose of Bending punch and the groove fit of lower bolster, a punching press realizes the bending of parts, and parts bending camber is consistent.
But these only complete bending by " V " the type groove by offering on bed die or " U " type groove or other shapes, although this cost is lower, but cannot meet the requirement of modern crafts to precision, especially electronic product, requirement for profile is more and more higher, and common bending machine mould sheet material when bending operation is that line contacts with mould, must cause the damage of sheet material, and bending part, due to the effect of power, can there is a point deformation in mould itself, especially middle (or the projection of can slightly sinking of mould, concrete condition is to sink or projection will act on mold or bed die is determined according to the active force of bender), this bending part that just causes the workpiece of institute's bending is not an absolute straight line, have slight bending, this can not meet the production requirement of modern crafts completely, especially cannot meet the bending requirement of high-end computer housing.
Summary of the invention
1. the technical problem that invention will solve
