Between punch 103 and die 108, form the bending mouth.
In the practical work process, bending punch 103 is bending downwards under the effect of punch press, with 108 mating reactions of bending die product 107 is converted into 90 ° and bends when dropping to certain depth.Product is once rolled over 90 ° when curved in mould, because all there is crooked bounce-back property in any metal material, the product angle is often greater than 90 ° after the bending, and difficulty reaches the Angular Dimension of the designed requirement of product.Often reduce gap between protruding, die in order to reduce rebound amount, as the strip thickness of processing is 0.5mm, then 0.47mm-0.48mm is adopted in the gap between protruding, the die, will make product produce serious galled spots like this in the bending process.
Summary of the invention
The applicant can abrade product surface at bending process in the above-mentioned existing production technology, influence the shortcoming of product processing quality, a kind of a bending, aligning gear rational in infrastructure are provided, thereby guarantee the bending angle, effectively reduce the scratch of product surface, guarantee product processing quality.
The technical solution adopted in the present invention is as follows:
An a kind of bending, aligning gear comprise upper die component and following membrane module,
The structure of described upper die component is: comprise upper bolster, described upper bolster bottom is equipped with upper die plate, described upper die plate bottom is equipped with punch retainer, punch is fixedly arranged on the described punch retainer, the bottom of described punch retainer also is equipped with discharging backing plate and stripper, and described punch passes discharging backing plate and stripper respectively;
Described becoming of membrane module down: comprise die shoe, the die backing plate is installed on the described die shoe, die block is installed on the described die backing plate, die is installed on the described die block;
Between punch and die, form the bending mouth;
Described punch is installed on the punch retainer by rotating shaft, and described punch bottom one side is provided with the inclined-plane; Be positioned on the die shoe to be equipped with tiltedly by screw and carve, the adjustment piece is fixedly arranged at the described top of tiltedly carving, and described adjustment piece top is provided with second inclined-plane that cooperates butt with the punch inclined-plane.
As further improvement in the technical proposal:
A described end of tiltedly carving is by regulating the bolt location.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, make with easy for installation, by rotatable punch with adjust cooperating between the piece, after it finishes bending, can carry out the bending adjustment simultaneously, a bending of assurance puts in place, effectively reduce product surface bending scratch, guarantee product processing quality.
The present invention adopts bending and correcting integrating design, finishes at same mould structure, reduces effective station quantity of mould, reduces cost, and increases work efficiency, and effectively reduces the galled spots of bending.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 3 and Figure 4, a bending of present embodiment, aligning gear comprise upper die component and following membrane module,
The structure of upper die component is: comprise upper bolster 101, upper bolster 101 bottoms are equipped with upper die plate 102, upper die plate 102 bottoms are equipped with punch retainer 104, punch 103 is fixedly arranged on the punch retainer 104, the bottom of punch retainer 104 also is equipped with discharging backing plate 105 and stripper 106, and punch 103 passes discharging backing plate 105 and stripper 106 respectively;
Becoming of following membrane module: comprise die shoe 111, die backing plate 110 is installed on the die shoe 111, die block 109 is installed on the die backing plate 110, die 108 is installed on the die block 109;
Between punch 103 and die 108, form the bending mouth;
Punch 103 is installed on the punch retainer 104 by rotating shaft 15, and punch 103 bottoms one side is provided with inclined-plane (not marking among the figure); Be positioned on the die shoe 111 to be equipped with by screw 14 and tiltedly carve 13, tiltedly carving 13 tops fixedly has the piece 12 of adjustment, adjusts piece 12 tops and is provided with second inclined-plane (not marking among the figure) that cooperates butt with punch 103 inclined-planes.
Tiltedly carve an end of 13 by regulating the bolt location.
The height of adjustment piece 12 of the present invention can be according to actual operating position, controls the height of adjusting piece 12 by tiltedly carving 13 position.
In the actual process, consistent with processing method of the prior art, after finishing 90 ° of curved finishing, punch 103 continues to move downward to be run into when adjusting piece 12, and the inclined-plane (not marking among the figure) of punch 103 1 sides and adjustment piece 12 second inclined-plane (not marking among the figure) butts are owing to adjust the restriction of piece 12,103 of punch, 15 the center of circle around the shaft clockwise rotate, the rotation of punch 103 promotes product 107 left simultaneously, makes the crooked excessive of product 107, to reach compensation bending springback capacity.
The present invention adopts normal bending gap, need not to reduce the gap and guarantees the bending angle, owing to being normal bending gap even abrading less greater than the product 107 that the thick bending gap of strip material produces.
After the present invention finishes bending work, smooth the bending angle immediately, control product 107 rebounds after bending, and its rebound amount is adjustable, controlled.And can do not reduce situation protruding, the die gap be issued to freely adjust the bounce-back compensation rate purpose.
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.
