Abstract

The invention discloses a ring washer production die and belongs to the technical field of mechanical device design. The ring washer production die comprises fixing shafts, a female die, core holes, counter bores, a male die, core shafts and tools. A female die body is a cuboidal plate. The counter bores are uniformly formed in the symmetric line, in the front-back direction, of the upper surface of the female die. Each core hole is machined in the center of the corresponding counter bore. The female die is fixed to a workbench through the fixing shafts. The male die is fixed to stand columns of a machine tool and located over the female die. The tools are arranged at the positions corresponding to the counter bores in the female die. Each core shaft is arranged in the center of the corresponding tool. In the machining process, a rectangular iron sheet is placed on the female die, the tools and the core shafts extends out of the male die and are inserted into the counter bores and the core holes of the female die, and ring washers can be formed through machining. The ring washer production die is simple in structure and convenient to machine; the female die is reliable in fixation, balanced in stress, high in production efficiency, low in cost and quick in blanking; components are not prone to deformation and high in formation precision; and the machining scope is wide.

Description

A kind of ring washer production mould

Technical field

The present invention relates to machinery design field, particularly relate to a kind of ring washer and produce Mould.

Background technology

Ring washer application in the middle of plant equipment is extremely extensive, particularly should in threaded connector With more extensive, ring washer size is little, and thickness is thin, uses traditional processing method pad easy Deformation, processing trouble, efficiency is low, and this kind of part uses at present more processing method for punching Cut out processing, due to simple with circular hole, general punch press die and punch structure in the middle of ring washer, Ring washer cannot be formed, after drift and cavity die structure are improved by some lathe, Ke Yijia Work goes out ring washer, but apparatus structure is complicated, and formed precision is the highest, lathe narrow application range, Therefore a kind of simple in construction of design, easy to process, and die is fixing reliable, and stress balance produces Efficiency is high, low cost, and blanking is fast, and part is unlikely to deform, and forming accuracy is high, and the range of work is wide Ring washer production mould necessary.

Summary of the invention

The purpose of the present invention is contemplated to overcome drawbacks described above, devises a kind of ring washer and produces mould Tool.

Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:

A kind of ring washer production mould, including fixing axle, die, described die body is a length Cube plate, described die uses described fixing axle fixing on the table, also includes core bore, sinks Hole, punch, mandrel, cutter, be positioned on the line of symmetry of upper surface fore-and-aft direction of described die Being evenly arranged with described counterbore, the center being positioned at described counterbore is machined with described core bore, institute State punch and be fixed on machine pillar the surface being positioned at described die, described with on described die Counterbore correspondence position is provided with described cutter, described cutter be provided centrally with described mandrel.

Described fixing axle arranges altogether four, is separately positioned on four angles of die.

Described core bore and described counterbore are machined with five on described die altogether, at described punch Bottom surface is provided with five described cutters and described mandrel.

The cutting edge of described mandrel and described cutter is arranged on the excircle of its bottom surface, described The edge of counterbore and described core bore is also machined to sharp orifice.

Described cutter is made up of six pieces of blades, and they are along the circumferential direction evenly provided on described core Around axle, between every two pieces of blades, all leave gap.

Owing to have employed above technical scheme, present invention have the advantage that

Fixing axle, die, core bore, counterbore, punch, mandrel, cutter is used to combine set The ring washer production mould of meter, fixing axle arranges altogether four, and die is fixing reliable, and stress is put down Weighing apparatus, core bore and counterbore are machined with five on die altogether, are also equipped with five in the bottom surface of punch Cutter and mandrel, production efficiency is high, and low cost, the cutting edge of mandrel and cutter is arranged at it On the excircle of bottom surface, the edge of counterbore and core bore is also machined to sharp orifice, and blanking is fast, Part is unlikely to deform, and forming accuracy is high, and cutter is made up of six pieces of blades, and they are along the circumferential direction Being evenly provided on around mandrel, all leave gap between every two pieces of blades, the range of work is wide, Equipment cost is low.

Detailed description of the invention

For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to effect Understand and understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.

A kind of ring washer production mould, including fixing axle 1, die 2, core bore 3, counterbore 4, Punch 5, mandrel 6, cutter 7, die 2 body is a cuboid plate, is positioned at die 2 It is evenly arranged with counterbore 4 on the line of symmetry of upper surface fore-and-aft direction, is positioned at the centre bit of counterbore 4 Putting and be machined with core bore 3, die 2 uses fixing axle 1 fixing on the table, and punch 5 is fixed Machine pillar is positioned at the surface of die 2, arranges with counterbore 4 correspondence position on die 2 Have cutter 7, cutter 7 be provided centrally with mandrel 6, add man-hour, on die 2 place one Block rectangular iron, punch 5 moves downwardly to the vicinity of die 2, cutter 7 and mandrel 6 from convex Mould 5 stretches out counterbore 4 and the core bore 3 inserting die 2, can be processed to form ring washer, device Simple in construction, easy to process.

Fixing axle 1 arranges altogether four, is separately positioned on four angles of die 2, die 2 Fixing reliable on the table, stress balance.

Core bore 3 and counterbore 4 are machined with five on die 2 altogether, also set in the bottom surface of punch 5 Being equipped with five cutters 7 and mandrel 6, therefore primary feed can process five ring washers, produces Efficiency is high, low cost.

The cutting edge of mandrel 6 and cutter 7 is arranged on the excircle of its bottom surface, counterbore 4 He The edge of core bore 3 is also machined to sharp orifice, and blanking is fast, and part is unlikely to deform, and shapes essence Degree height.

Cutter 7 is made up of six pieces of blades, and they are along the circumferential direction evenly provided on mandrel 6 Around, all leave gap between every two pieces of blades, add man-hour, can be by adjusting every two pieces of cuttves Between sheet, the size in gap conveniently realizes the processing of different radial dimension of ring washer, adapts to model Enclosing wide, equipment cost is low.
