Abstract
A bending scratch-proof structure comprises a bending floating block. A second bending embedded block is installed at one end of the bending floating block, a 90-degree bending face is arranged at one end of the second bending block, the first right-angle face of the second bending embedded block is flush with the upper plane of the bending floating block, a material belt is arranged on the second bending embedded block and the bending floating block, a bending male die which is matched with the first bending embedded block and the bending floating block is arranged on the upper portions of a first bending embedded block and the bending floating block, a rolling needle is installed on the second right-angle face of the second bending embedded block, and the rolling needle rolls along the second right-angle face of the second bending embedded block. The bending scratch-proof structure is reasonable in structure, simple and convenient to operate, and makes contact with the surface of the material belt through the rolling needle from beginning to end, so that scratch of the surface of the material belt is effectively avoided, processing quality of the products is ensured, and processing requirements are met. In addition, molding can be achieved for one time simply by using one set of molding dies, the trouble operation that two sets of molding dies are required to be adopted in the prior art is avoided, cost is reduced, and working efficiency is improved.
Description
Technical field
The present invention relates to die device, the anti-scratch of especially a kind of bending mould structure.
Background technology
In Bending Mould, through regular meeting the abrasive situation of product folding surface appears.In the product technology of a lot of bendings, some folding surface requires that scratch cannot be arranged, and appearance requirement is than higher.
In the prior art, as depicted in figs. 1 and 2, usually adopt two cover Bending Moulds, be respectively and pre-fold mould and mould, as shown in Figure 1, the structure of described Bending Mould is: comprise bending floating block 3, one end of described bending floating block 3 is equipped with first bending and goes into piece 4, the end that piece 4 is gone in described first bending is provided with 45 ° of inclined-planes, described first bending is gone into piece 4 and is arranged between a bevelled end and the bending floating block 3 and to constitute 135 ° of angles, is positioned at first bending and goes on piece 4 and the bending floating block 3 to place strip 2, is positioned at first bending and goes into piece 4 and be provided with the bending punch 1 that cooperates with it with bending floating block 3 tops, when described bending punch 1 moves downward, strip 2 is bent into 135 °;
As shown in Figure 2, the structure of described mould is: comprise bending floating block 3, described bending floating block 3 one ends are equipped with second bending and go into piece 6, the end that piece 6 is gone in described second bending is provided with 90 ° of folding surfaces, planar registration on the first right angle face of piece 6 and the bending floating block 3 is gone in described second bending, described second bending goes into to place strip 2 on piece 6 and the bending floating block 3, being positioned at first bending goes into piece 4 and is provided with the bending punch 1 that cooperates with it with bending floating block 3 tops, when described bending punch 1 moves downward, the strip 2 that is bent into 135 ° is bent into 90 ° again.
During bending, it is at 45 with the product bending to pre-fold mould, and then adopt mould with 90 ° of formed product, be that the stability of bender is improved greatly like this, but in the bending process, the folding surface of product is to contact the surface that piece is gone in bending all the time, and its injurious surface mark of product is bigger, influences product quality.It fails effectively to solve the abrasive problem of folding surface, does not satisfy the demand of product processing.
Summary of the invention
The applicant is at the easy abrasive shortcoming of product folding surface in the above-mentioned existing production technology, the anti-scratch of a kind of bending mould structure is provided, thereby utilize the rolling pin in the bending process with the strip surface engagement, significantly reduce the scratch on institute converted products surface, guarantee the crudy of product, reduce the processing cost of mould, increase work efficiency.
The technical solution adopted in the present invention is as follows:
The anti-scratch of a kind of bending mould structure, comprise the bending floating block, described bending floating block one end is equipped with second bending and goes into piece, the end that piece is gone in described second bending is provided with 90 ° of folding surfaces, planar registration on the first right angle face of piece and the bending floating block is gone in described second bending, described second bending goes on piece and the bending floating block to place strip, being positioned at first bending goes into piece and is provided with the bending punch that cooperates with it with bending floating block top, described second bending goes on the second right angle face of piece the rolling pin is installed, and the second right angle face that described rolling pin is gone into piece along second bending rolls.
As further improvement in the technical proposal:
Described rolling pin contacts with the folding surface of strip all the time;
Described rolling pin is hard alloy bar;
Described bending punch is provided with the discharging thimble.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, and is easy and simple to handle, in the bending process, all the time in the contact of strip surface, effectively avoids the scratch on strip surface by the rolling pin, guarantees the crudy of product, satisfies processing request.Only need in addition to adopt a sleeve forming mould, but one-shot forming finish, avoided needing in the prior art to adopt the troublesome operations of two molds, reduce cost, increase work efficiency.

Wherein: 1, bending punch; 2, strip; 3, bending floating block; 4, piece is gone in first bending; 5, discharging thimble; 6, piece is gone in second bending; 7, rolling pin.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 3, the anti-scratch of the bending of present embodiment mould structure, comprise bending floating block 3, bending floating block 3 one ends are equipped with second bending and go into piece 6, the end that piece 6 is gone in second bending is provided with 90 ° of folding surfaces, planar registration on the first right angle face of piece 6 and the bending floating block 3 is gone in second bending, second bending goes into to place strip 2 on piece 6 and the bending floating block 3, being positioned at first bending goes into piece 4 and is provided with the bending punch 1 that cooperates with it with bending floating block 3 tops, second bending goes on the second right angle face of piece 6 rolling pin 7 is installed, and the second right angle face that rolling pin 7 is gone into piece 6 along second bending rolls.
Rolling pin 7 contacts with the folding surface of strip 2 all the time.
Rolling pin 7 is hard alloy bar.Adopt carbide alloy can reduce the distortion of rolling pin 7.
Bending punch 1 is provided with discharging thimble 5.
In the actual use, strip 2 is positioned over second bending goes on piece 6 and the bending floating block 3, the 1 downward punching press of bending punch, simultaneously, be positioned at second bending go into rolling pin 7 on the piece 6 second right angle faces along right angle that strip 2 forms gradually towards last rolling, finish for 90 ° until strip 2 bendings.
The present invention has effectively avoided the scratch of strip 2 folding surface in the bending process, the working face of going into piece in bending adds a rolling pin 7, reduced strip 2 and bending greatly and gone into frictional force between the piece, the fineness on strip 2 surfaces is greatly improved, and satisfies the crudy requirement.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
