Abstract
The invention discloses a punching technique for cambered surface punch forming. The punching technique comprises the following steps: a) punching and trimming: performing punching blanking processing on a to-be-processed workpiece, and then blanking an edge of the workpiece, thereby acquiring the shape and size required by the workpiece; b) raising and pressing a rough edge: raising the workpiece, and then performing rough edge pressing treatment on a mould after raising; c) forming radian: utilizing the upper and lower mould characteristics of a mould to finish the forming of the workpiece from a plane to a cambered surface; d) step forming and bending: performing step treatment on the formed cambered surface and bending the opposite angles on the two sides of the cambered surface, wherein the bending angle is at 30 degrees; f) laterally pushing and flattening: utilizing lateral pushing flattening devices on the two sides of the mould to laterally push and flatten the local surface of the workpiece. According to the technique, the structure is reasonable, the quality problem during a forming process of the cambered surface is effectively relieved, the precision of the formed cambered surface is ensured, the damage to the mould during the forming process is effectively reduced, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of punch forming process, be specially the stamping forming Sheet Metal Forming Technology of a kind of cambered surface.
Background technology
Mould is manufacturing important process basis, and in China, Making mold belongs to special equipment manufacturing.Diel is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die.Punching press is at room temperature, utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.
At present, the product major part of diel punching press is that plane has been main, and Sheet Metal Forming Technology mainly comprises: take out dark, punching, raising, deburr or coin, shaping, the operation such as cut, Sheet Metal Forming Technology is very high to the required precision of technique, if wherein a procedure cannot meet technological requirement, finishing operations widens the error of workpiece further, thus workpiece cannot be used, cause scrapping of workpiece.And the punch forming of cambered surface, require higher to processing technology, because easily produce offset in curved face processing process, and due to the continuous punching process of mould, cause workpiece cambered surface radian inadequate, also easily produce the distortion of cambered surface, meanwhile, in cambered surface, raising, punching operation are also important topics in moulding process.
Therefore, for the problems referred to above, the present invention spy improves a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of technique simple, formed precision is high, damages the stamping forming Sheet Metal Forming Technology of little cambered surface to mould.
The present invention is achieved through the following technical solutions:
The stamping forming Sheet Metal Forming Technology of a kind of cambered surface, comprises following process:
A, punching, trimming: carry out punching punch press process to workpiece to be processed, then carry out stamping-out to the edge of work, to obtain the shape and size of workpiece requirement;
B, raising, deburr or coin: raising is carried out to workpiece, the mould then raising completed carries out deburr or coin process;
C, beat radian: utilize the upper and lower module feature of mould, complete workpiece by the shaping of plane to cambered surface;
D, interrupt poor, bending: carry out offset process to shaping cambered surface, and carry out bending to the diagonal angle, both sides of cambered surface, the angle of bending is 30 degree;
F, thruster, to clap: utilize the ambilateral thruster pressuring flat device of mould to carry out thruster to the partial face of workpiece and clap.
Further, before carrying out above-mentioned operation, first pretreatment is carried out to mould.
Further, in described operation b, rivet is squeezed into the convex closure be shaped.
Further, in described operation c, patrix concave surface, counterdie is convex surface, utilizes the cambered surface forming process that cooperatively interacted of upper die and lower die.
The invention has the beneficial effects as follows: this process structure is reasonable, effectively alleviates quality problems in cambered surface forming process, ensures shaping cambered surface precision, with the damage entering to efficiently reduce to mould in forming process, reduce production cost.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail.
The stamping forming Sheet Metal Forming Technology of a kind of cambered surface, comprises following process: a, punching, trimming: carry out punching punch press process to workpiece to be processed, then carries out stamping-out to the edge of work, to obtain the shape and size of workpiece requirement; B, raising, deburr or coin: raising is carried out to workpiece, the mould then raising completed carries out deburr or coin process; C, beat radian: utilize the upper and lower module feature of mould, complete workpiece by the shaping of plane to cambered surface; D, interrupt poor, bending: carry out offset process to shaping cambered surface, and carry out bending to the diagonal angle, both sides of cambered surface, the angle of bending is 30 degree; F, thruster, to clap: utilize the ambilateral thruster pressuring flat device of mould to carry out thruster to the partial face of workpiece and clap.Before carrying out above-mentioned operation, first locate in advance mould, in operation b, squeeze into rivet to the convex closure be shaped, in operation c, patrix concave surface, counterdie is convex surface, utilizes the cambered surface forming process that cooperatively interacted of upper die and lower die.This process structure is reasonable, effectively alleviates quality problems in cambered surface forming process, ensures shaping cambered surface precision, with the damage entering to efficiently reduce to mould in forming process, reduces production cost.
