Abstract
The utility model relates to a prevent workpiece abrasion's die, die body including the cuboid form, the middle part from the top down of die body has seted up rectangle step portion, die V type portion, spout and liftout piece mounting groove respectively, set up little screw hole and little cotter hole that the installation locating piece was used in the rectangle step portion, the surface of die V type portion is provided with the abrasionproof protective layer, still set up the screw hole and the cotter hole of installation fastening usefulness on the die body. The utility model discloses a die is used on the bending die, can effectually avoid crooked process in -process scotch work piece, has improved the finished product precision of work piece, has guaranteed production quality.
Description
Technical field
The utility model relates to a kind of for processing the mould of hinge gasket piece, refers in particular to a kind of bending die die that can effectively prevent the wear of work in bending operation.
Background technology
Bending process is the needs according to part shape, by mould and forcing press, blank is curved to the Sheet Metal Forming Technology method of certain angle, definite shape workpiece. Attachedly Figure 1 shows that middle hinge gasket piece, this part is typical V-arrangement part, workpiece shape, relatively simple for structure, and also symmetrical, normally to produce in enormous quantities, this part mainly contains Blanking Shaping and bending twice manufacturing procedure. In bending process, need to ensure the bright and clean and no marking of curved rear piece surface, conventionally be also the important required precision project of bool, but bending die of the prior art in the course of the work, due to workpiece and the generation friction of die surface, more or less can make the surface of bool occur damage, reduce the quality of workpiece, affect the form and dimensional precision of workpiece.
Utility model content
The utility model object is to have proposed a kind of die that can make the high and anti-wear of work of bending machining precision in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of die of the anti-wear of work, comprises the die body of cuboid; The middle part of described die body offers respectively rectangle stage portion, die V-type portion, chute and ejection block mounting groove from top to bottom; In described rectangle stage portion, offer Screw hole and the little pin hole that locating piece is used is installed; The surface of described die V-type portion is provided with abrasionproof protective layer; On described die body, also offer screw hole and pin hole that fastening use is installed.
Preferably, described abrasionproof protective layer thickness is 0.3 ~ 0.5mm.
Preferably, the angle of described die V-type portion is set to 87 ° ~ 88 °.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The die of the anti-wear of work of the present utility model; be provided with abrasionproof protective layer at die upper surface; can solve the problem of carrying out the violent sliding friction in workpiece and die surface in process and form scratch in bending; effectively avoid abrading workpiece; improve the forming quality of workpiece, effectively improved the dimensional accuracy of workpiece.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is cavity die structure schematic diagram of the present invention;
Accompanying drawing 2 is that A-A of the present invention is to cutaway view;
Wherein: 1, die body; 2, rectangle stage portion; 3, die V-type portion; 4, chute; 5, ejection block mounting groove; 6, Screw hole; 7, little pin hole; 8, abrasionproof protective layer; 9, screw hole; 10, pin hole.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
The cavity die structure of the anti-wear of work of the present invention, as shown in accompanying drawing 1 ~ 2, comprises the die body 1 of cuboid; The middle part of described die body 1 offers respectively rectangle stage portion 2, die V-type portion 3, chute 4 and ejection block mounting groove 5 from top to bottom; In described rectangle stage portion 2, offer Screw hole 6 and the little pin hole 7 that locating piece is used is installed; The surface of described die V-type portion 3 is provided with abrasionproof protective layer 8, described abrasionproof protective layer 8 can solve the problem of carrying out the violent sliding friction in workpiece and die surface in process and form scratch in bending, effectively avoid abrading workpiece, improve the forming quality of workpiece, effectively improved the dimensional accuracy of workpiece; On described die body 1, also offer screw hole 9 and pin hole 10 that fastening use is installed, for die is arranged on to die socket.
Embodiment mono-: described abrasionproof protective layer 8 thickness are 0.3mm, the angle of described die V-type portion 3 is set to 88 °, has considered the springback angle of workpiece.
Embodiment bis-: described abrasionproof protective layer 8 thickness are 0.5mm, the angle of described die V-type portion 3 is set to 87 °, has considered the springback angle of workpiece.
The die of the present invention program's the anti-wear of work, its course of work is: first die and supporting punch are arranged on bending die, and are arranged on workbench, then mix suitable forcing press to bending die; The workpiece to be bent of Blanking Shaping is put into die, by being arranged on the locating piece location on die. Mould is in the time of work, and punch is descending with forcing press, and after punch contacts with workpiece, workpiece starts to be bent to workpiece contact and is arranged on the kicker in the chute of die middle part under the work that presses down of punch, then works Work-sheet pressing at kicker and die one. Forcing press backhaul is up, and punch is and then up together, and the workpiece of bending forming is released by kicker under the effect of recoil of spring power, and finished work-piece is taken off, and completes the bending operation of a workpiece.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation. All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
