Description

A kind of pressing and bending squeezes inclination angle mould
Technical field
Inclination angle mould is squeezed the present invention relates to a kind of pressing and bending.
Background technology
With the development of punching press industry and pushing away newly for science and technology, stamping parts quality requirement is uprised.It is required that sheet metal component product is rolled over The outer R angles of crimp are R0.1-R0.2, also or require that outer bending edges are inclination angle, this R angles size less than sheet metal thickness, after bending Required R angles size can not be reached.Need to be realized by other techniques.
License notification number CN201776344U discloses a kind of fast press die with bending punch pin, including mould on And once mould, the space for shaped article is reserved between the upper mould and lower mould, wherein, the upper mould is main by upper mould Seat, train wheel bridge, upper backboard, upper masterplate overlap form successively, and wherein, the lower mould by lower template, lower bolster, die shoe according to It is secondary overlapping and put, the train wheel bridge is vertically and fixedly provided with hemisection drift, and the train wheel bridge is vertically and fixedly provided with for being rolled over to product Curved bending punch pin.The present invention disclose band bending impact fast press die, when upper mould is moved down, bending punch pin with Hemisection drift also follows it to move down, and is first cut product by hemisection drift, then product under being cut by bending punch pin enters Row bending, therefore, reach one-time formed purpose.But the mould can not still realize size of the R angles of bending needed for.
The content of the invention
The shortcoming of prior art, inclination angle mould is squeezed it is an object of the invention to provide a kind of pressing and bending in view of the above Tool, can make bending edges for inclination angle after punching press, prevent the generation of burr during ram extrusion inclination angle.
In order to achieve the above objects and other related objects, the present invention provides a kind of pressing and bending and squeezes inclination angle mould, including upper Mould bases plate and lower mold holder plate, the top mold frame plate have punch-pin, loading and unloading material plate are provided with the punch-pin, on the lower mold holder plate Be provided with lower mold fixed plate, the lower mold fixed plate is provided with cavity plate, be provided with lower stripper in the cavity plate, the loading and unloading material plate with Rectangular coil spring one is provided between the top mold frame plate, rectangular coil is provided between the lower stripper and the lower mold holder plate Spring two.
Preferably, be provided with the gap of 0.01-0.02mm between the loading and unloading material plate and the punch-pin, the lower stripper with The gap of 0.01-0.02 mm is provided between the cavity plate.Loading and unloading material plate can in punch-pin normal work, while product can be ensured The perpendicularity of bending edges.If gap is excessive, in punching press, the downward punching press of punch-pin, product bending edges to lower stress extrded material, this When between loading and unloading material plate and punch-pin, gap is excessive between loading and unloading material plate and cavity plate, material can crimp, influence product quality. Lower gap between stripper and cavity plate, for ensureing while normal discharging, binder, to prevent hair during ram extrusion inclination angle The generation of thorn.If gap between the two is excessive, in punching course, punch-pin is pressed down against material, and material is pressed into down Between stripper and cavity plate during gap location, burr can be produced.
Preferably, the side of the cavity plate is provided with inner guiding post or outer guiding post, or is provided with inner guiding post and outer guiding post simultaneously.With In correcting mould, it is ensured that mould and die accuracy.
Preferably, the loading and unloading material plate is connected on the top mold frame plate by stripper bolt one, and the lower stripper leads to Stripper bolt two is crossed to be connected in the lower mold fixed plate.
Preferably, the loading and unloading material plate is provided with nitrogen spring.Because product is higher to planarity requirements, mould punching is squeezed During pressure, the extruding of product stress, if pressure-plate-force not enough, has the trend for producing and arching upward upwards, can influence product plane degree.Upper mould Ensure product plane degree using nitrogen spring.
Preferably, the lower surface of the top mold frame plate is provided with counterbore, and the loading and unloading material plate upper surface is provided with counterbore, the square Shape helical spring one is placed in the counterbore of top mold frame plate and loading and unloading material plate, it is ensured that loading and unloading material plate normal binder in punching course Discharging.
Preferably, it is additionally provided with a backing plate below the top mold frame plate.
Upper mould(Mould open mode, is installed on punch press upper table surface part)Using floating press material structure, loading and unloading material plate is simultaneously Binder effect is played, is connected by stripper bolt, counterbore is processed on top mold frame plate, make the loading and unloading material plate can be in certain stroke range Move up and down.Lower mould(Mould open mode, is installed on punch press following table part)Using buoyant structure, after making to press in a state of excitement completion Product can smoothly be picked and placeed by jack-up.Lower mould stripper is fixed using stripper bolt, respective aperture is processed in lower mould and places bullet Spring, coordinating stripper bolt to be used together makes lower mould stripper normally can be moved up and down in stripper bolt stroke.
Preferably, by positioning finger setting between the punch-pin and the cavity plate.
In sum, a kind of pressing and bending of the invention is squeezed inclination angle mould and is had the advantages that:Realize aluminium case Tortuous crimp R angles extruding is the processing at inclination angle.Loading and unloading material plate can in punch-pin normal work, while product bending edges can be ensured Perpendicularity.While ensureing normal discharging, binder, the generation of burr during ram extrusion inclination angle is prevented.
