Abstract

The utility model relates to a rotary -cut forming device of circular tensioning member, include upper die base, punch holder, lower bolster, take off flitch, die holder, upper die base center part has vertical migration's guide arm and the guide arm lower extreme sets up the deflector, set up the cam in the deflector mounting groove, deflector below take off the flitch on fixed mounting die socket slide wedge and set up rotatable rotary -cut die on the die socket slide wedge, a lower mould floating block is add to lower bolster top surface fixed mounting rotary -cut terrace die above the rotary -cut terrace die. The utility model discloses beneficial effect does: the detachable trims the tensioning member many times on request, and the air -blowing play is used through lower mould floating block jack -up in the back, it is rational in infrastructure, the rotary -cut steady quality, production efficiency is high, and is with low costs.

Description

A kind of rotary-cut shaped device of circular tensioning member

Technical field

The utility model relates to Stamping Die Technology, particularly relates to a kind of rotary-cut shaped device of circular tensioning member.

Background technology

Nowadays, all take much count of the research of punch forming theory both at home and abroad, also make great progress in many aspects, along with the perfect further of theory and the development of computer technology; The part of punch process is of a great variety, and part shape, size and required precision are different, and in thus producing, Sheet Metal Forming Technology method is also varied.Generally speaking, separation circuit and the large class of forming process two is divided into; Separation circuit is the operation that the stamping parts of instigating blank to obtain definite shape, size and cross section quality along the separation of certain outline line is commonly called as blanking part; Forming process is that blank produces the distortion of plasticity thus obtains the operation of the stamping parts of certain size under condition of not breaking.This two classes operation, be divided into again four kinds of basic working procedure such as stamping-out, bending, drawing, shape mould by basic deformation mode difference, often kind of basic working procedure is again containing many single operations.

This case it is important to note that, the innovation carrying out diel is needed for the high cost of current flange cylindrical member manufacture, low production efficiency situation, reason is that traditional similar mould structure is unreasonable, rotary-cut quality is lower, primary structure is that the position of concave-convex mold coordinates poor, lack guide, tensioning member rotary-cut inaccuracy.Thus, for circular tensioning member, need the rotary-cut of design one cuff to go out the multi-station progressive die of part.

For above aspect, need reasonably to improve prior art.

Utility model content

For above defect, the utility model provides the rotary-cut shaped device of the circular tensioning member that a kind of mould structure is reasonable, rotary-cut steady quality, production efficiency are high, cost is low, to solve many deficiencies of prior art.

For achieving the above object, the utility model is by the following technical solutions:

A kind of rotary-cut shaped device of circular tensioning member, comprise upper bolster, train wheel bridge, lower bolster, stripper plate, die shoe, below train wheel bridge, stripper plate is set, above die shoe, lower bolster is set, described upper bolster centre with vertical movement guide rod and lower end of the guide rod arranges guide plate, in described guide plate mounting groove, cam is set, meanwhile, the stripper plate below described guide plate fixedly mounts die socket wedge and rotatable rotary-cut die is set on die socket wedge; Described lower bolster end face fixed installation rotary-cut punch, sets up a counterdie floating block above rotary-cut punch.

Correspondingly, described rotary-cut die top is with rotating mechanism;

Described rotary-cut die is peripheral with mobile guide post;

Described rotary-cut punch inner surface is with helicoid.

The beneficial effect of the rotary-cut shaped device of circular tensioning member described in the utility model is: this structure is primarily of guide plate cam and die socket wedge composition, in punching course, by the rotary-cut die being fixed on patrix, go downwards to the rotary-cut punch being fixed on counterdie, contacted with the cam path of four pieces of guide plate mutual dislocation by the profile wedge of die socket, in conjunction with patrix move both vertically formed similar screw, several times tensioning member is trimmed on request, after gone out with air-blowing by counterdie floating block jack-up; Rational in infrastructure, rotary-cut steady quality, production efficiency is high, and cost is low, obtains good technology and economic benefit.

Accompanying drawing explanation

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of the rotary-cut shaped device of circular tensioning member described in the utility model embodiment.

In figure:

1, upper bolster; 2, upper padding plate; 3, train wheel bridge; 4, lower bolster; 5, stripper plate; 6, die shoe; 7, counterdie floating block; 8, guide plate; 9, cam; 10, die socket wedge; 11, rotary-cut die; 12, rotary-cut punch.

Detailed description of the invention

As shown in Figure 1, the rotary-cut shaped device of the circular tensioning member described in the utility model embodiment, comprise upper bolster 1, upper padding plate 2, train wheel bridge 3, lower bolster 4, stripper plate 5, die shoe 6, below train wheel bridge 3, set gradually stripper plate 5, lower bolster 4 is set above die shoe 6; Described upper bolster 1 centre with vertical movement guide rod and lower end of the guide rod arranges guide plate 8, described guide plate 8 inside is offered two mounting grooves and in groove, arranges cam 9, meanwhile, the stripper plate 5 below described guide plate 8 fixedly mounts die socket wedge 10 and rotatable rotary-cut die 11 is set on die socket wedge 10; Described lower bolster 4 end face fixedly mounts rotary-cut punch 12 and above rotary-cut punch 12, sets up a counterdie floating block 7.

The rotary-cut shaped device of the circular tensioning member described in above the utility model embodiment, in punching course, by the rotary-cut die being fixed on patrix, go downwards to the rotary-cut punch being fixed on counterdie, contacted with the cam path of guide plate mutual dislocation by the profile wedge of die socket, in conjunction with patrix move both vertically formed similar screw, several times tensioning member is trimmed on request, after gone out with air-blowing by counterdie floating block jack-up; Produce checking through die trial, mould structure is reasonable, and rotary-cut steady quality, production efficiency is high, and cost is low.

The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
