Abstract

The utility model relates to a work piece rectangular mould of bending, including base and die body, be equipped with the spacing groove on the die body, the last fixed surface of die body and base is connected, the upper surface of base is 6 with the contained angle A of horizontal plane, the die body upper surface has the face of bending, and the face of bending is 84 with the side contained angle B of spacing groove, the tank bottom of spacing groove is equipped with the flexible lining board. The utility model discloses make the negative angle degree on the mould, occupation space is little, and the processing cost is low.

Description

Workpiece is bent into the mould at right angle

Technical field

This utility model relates to a kind of Bending Mould, particularly relates to the mould being bent into right angle of a kind of thin plate.

Background technology

When a light sheet products needs folding an angle of 90 degrees to spend, because having resilience under force, often reach not To 90 degree, existing method is the pattern using and tiltedly digging block, and the block that tiltedly digs making negative angle is carrying out bending. Occupying very much owing to tiltedly digging the structure of block, use space big, some mould does not has the most so because of the problem of structure Many positions, and processing cost is the highest.

Summary of the invention

The purpose of this utility model is to provide one to make negative angle on mould, takes up room little, processing The workpiece of low cost is bent into the mould at right angle.

In order to achieve the above object, the technical solution of the utility model is: a kind of workpiece is bent into the mould at right angle Tool, including base and die body, described die body is provided with stopper slot, and die body is fixing with the upper surface of base to be connected, The upper surface of described base and the included angle A of horizontal plane are 6 °, and described die body upper surface has folding surface, bending Face is 84 ° with the side included angle B of stopper slot.

The bottom land of described stopper slot is provided with flexible backing plate.

After using said structure, die body is tilted by this utility model by the angle A of base, when workpiece is placed After in the stopper slot of die body, workpiece can be made to tilt, facilitate and press under vertical drift, make workpiece toward die body Folding surface tilts.Die body while making angle B, after workpiece bending shape in 90 ° more than, after drift is lifted, The phenomenon of resilience after counteracting bending.Therefore this utility model tiltedly digs block without other manufacture, and reduction takes up room, Just on mould, sheet workpiece can be washed into right angle, reduce processing cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

This utility model is described in further detail by the embodiment be given below in conjunction with accompanying drawing.

Shown in Figure 1, a kind of workpiece is bent into the mould at right angle, including base 1 and die body 2, described mould Body 2 is provided with stopper slot 21, and die body 2 is fixing with the upper surface of base 1 to be connected, the upper table of described base 1 Face is 6 ° with the included angle A of horizontal plane, and described die body 2 upper surface has folding surface 3, and folding surface 3 is with spacing The side included angle B of groove 21 is 84 °.

Shown in Figure 1, in order to, in Forging Process, not injure the lower surface of workpiece 5, described stopper slot The bottom land of 21 is provided with flexible backing plate 4.

Shown in Figure 1, this utility model by base 1 by die body and horizontal plane 6 °, when workpiece 5 After being placed in the stopper slot 21 of die body 2, workpiece 5 can be made to tilt, facilitate and press under vertical drift, make work Part 5 tilts toward the folding surface 3 of die body 2.Die body 2 while making angle B, after workpiece 5 bending formed More than 90 °, after drift is lifted, the phenomenon of resilience after counteracting bending.Therefore this utility model is without additionally system Deflecting digs block, and reduction takes up room, and just on mould, sheet workpiece 5 can be washed into right angle, and reduction is processed into This.It was verified that the included angle A of the upper surface of base 1 and horizontal plane is 6 °, folding surface 3 and stopper slot The side included angle B of 21 is 84 °, and two above angle can offset the resilience of workpiece 5 so that workpiece 5 exists 90 ° of angles it are exactly in after bending.

Above-described is only preferred implementation of the present utility model, it is noted that general for this area For logical technical staff, on the premise of creating design without departing from this utility model, it is also possible to make some changes Shape and improvement, these broadly fall into protection domain of the present utility model.
