Abstract

The utility model discloses double bending and folding die of a bending machine that pertains to the technical field of die. The utility model comprises an upper die and a lower die which are provided with corresponding wedge shaped working surfaces. The lower die is fixed on a lower die seat whose lower part is provided with a glide rod, a pedestal is provided with a guide cavity, the glide rod extends into the guide cavity. The lower die and the pedestal are provided with plane working surfaces opposite to each other and which are arranged with a certain interval. A spring is installed between the glide rod and the bottom of the guide cavity. When the lower die seat moves downward to press the spring, the plane working surfaces on the lower die seat and the pedestal will approach mutually together. In use, the work of bending and folding can be carried out at the same time without replacing die. Compared with prior art, the utility model can improve work efficiency effectively. The utility model can not only be applied on a bending machine but also on a press also.

Description

Die Bending Machine Two-fold
Technical field
The utility model relates to a kind of mould, particularly a kind of flanging mould.
Background technology
When utilizing the work of bender flanging, need to use Bending Mould and flanging mould, the mould that is used for flanging in the prior art mainly includes sharp knife mould and flattening die, these two kinds of moulds are formed by upper die and lower die, upper die and lower die are provided with corresponding working face, the working face of sharp knife mould is corresponding mutually wedge shape, the working face of flattening die is two horizontal planes, counterdie and die shoe fix, patrix and bender slide block relative fixed, slide block pumps, and is placed on workpiece between the upper die and lower die under the interaction of wedge shape working face, with the workpiece bending; When needing further flanging, need process once more with flattening die, add man-hour, the workpiece of bending was fallen on the working face of flattening die counterdie, slide block drives the patrix action, and the both sides of bending are pressed against together mutually; Above-mentioned sharp knife mould and flattening die also can be arranged on the counterdie, promptly on the not coplanar of counterdie, lozenges and plane are set, or lozenges and plane are set at the diverse location of the identical faces of counterdie, but no matter above-mentioned which kind of design, all need to readjust or mold exchange more, its operating efficiency is low.
The utility model content
The purpose of this utility model provides a kind of Die Bending Machine Two-fold, makes two steps of flanging work not adjust or more can realize simultaneously under the prerequisite of mold exchange.
The purpose of this utility model is achieved in that Die Bending Machine Two-fold, comprise upper die and lower die, upper die and lower die are provided with corresponding wedge shape working face, counterdie and die shoe fix, the die shoe downside is provided with sliding bar, described sliding bar stretches into downwards in the guiding cavity that is provided with on the base, the plane working face that die shoe and base are provided with mutual correspondence and keep at a certain distance away, be provided with spring between sliding bar and the guiding cavity inner bottom part, when die shoe moved downward the compression spring, the plane working face on die shoe and the base was pressed close to mutually.
During the utility model work, workpiece before the bending can be placed between the upper die and lower die, one side with the workpiece of bending is placed on the plane working face of base simultaneously, and the bender slide block drives patrix and moves downward, and the wedge shape working face will be placed on the workpiece bending between the upper die and lower die; Simultaneously, patrix is pushed counterdie and is driven die shoe and overcome spring tension and move downward, and the plane working face on die shoe and the base is pressed close to mutually, with being positioned over the two bending edges extruding of the workpiece on the plane working face of base and abutting in together, finishes flanging work.The above-mentioned course of work as can be seen, bending and flanging work can be carried out simultaneously, can increase work efficiency; On the other hand, because of not needing more mold exchange, also can increase work efficiency.Compared with prior art, the utility model can be increased work efficiency greatly, and it not only can be applied on the bender, also can be applied on the forcing press.
Above-mentioned sliding bar can be connected as a single entity with die shoe, carries out integrally manufacturedly, to reduce attaching parts, improves bonding strength.
Tension force during for adjustment spring flanging, described sliding bar is the hollow tubular of upper end sealing, lower ending opening, and spring top is stretched in the hollow space of sliding bar, and the spring upper end is provided with spring base, the adjusting screw(rod) that has been threaded on the die shoe, adjusting screw(rod) is vertical conflicts in the spring base upper end.Push spring base by adjusting screw(rod) and move down, the amount of contraction in the time of then can adjusting spring work, the adjustment of spring tension when realizing flanging.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is another working state figure of the utility model;
Wherein, 1 patrix, 2 wedge shape working faces, 3 counterdies, 4 adjusting screw(rod)s, 5 die shoes, 5a sliding bar, 6 spring bases, 7 springs, 8 guiding cavitys, 9 bases, 10 plane working faces, the workpiece before the 11a bending, the workpiece after the 11b bending.
The specific embodiment
As figure, Die Bending Machine Two-fold, comprise patrix 1 and counterdie 3, patrix 1 and counterdie 3 are provided with corresponding wedge shape working face 2, counterdie 3 fixes with die shoe 5, die shoe 5 downsides are provided with the sliding bar 5a that is connected as a single entity with die shoe 5, sliding bar 5a stretches into downwards in the guiding cavity 8 that is provided with on the base 9, the plane working face 10 that die shoe 5 and base 9 are provided with mutual correspondence and keep at a certain distance away, be provided with spring 7 between sliding bar 5a and guiding cavity 8 inner bottom parts, when die shoe 5 moved downward compression spring 7, the plane working face 10 on die shoe 5 and the base 9 was pressed close to mutually; Sliding bar 5a is the hollow tubular of upper end sealing, lower ending opening, and spring 7 tops are stretched in the hollow space of sliding bar 5a, and spring 7 upper ends are provided with spring base 6, the adjusting screw(rod) 4 that has been threaded on the die shoe 5, and adjusting screw(rod) 4 is vertically conflicted in spring base 6 upper ends.
During work, workpiece 11a before the bending can be placed between patrix 1 and the counterdie 3, simultaneously between the plane working face 10 that is placed on base and die shoe with the workpiece 11b after the bending, the bender slide block drives patrix and moves downward, and the wedge shape working face will be placed on the workpiece bending between the upper die and lower die; Simultaneously, patrix is pushed counterdie and is driven die shoe and overcome spring tension and move downward, and the plane working face on die shoe and the base is pressed close to mutually, with being positioned over the two bending edges extruding of the workpiece on the plane working face of base and abutting in together, finishes flanging work.Push spring base by adjusting screw(rod) and move down, the amount of contraction in the time of then can adjusting spring work, the adjustment of spring tension when realizing flanging.
