Abstract
The utility model discloses a kind of coder axle for elevator traction machine, comprise bar portion and flange, described bar portion and flange are individual components, and the centre of described flange is provided with step, described bar portion and flange are at described step place by being welded to connect, and described bar portion is an elongated cylinder.The utility model can Simplified flowsheet, after using raw MAT'L prtreatment respectively, adopts friction welding weld together, finally carries out fine limit work.After this design, stock utilization is improved, both can saves forging, and save raw MAT'L again, and reduce machinework productive costs.
Description
Technical field
The utility model relates to a kind of elevator traction machine, and specifically, what relate to is a kind of coder axle for elevator traction machine, is mainly used in the parts of elevator machine brake part.
Background technology
Along with the process of urbanization, the development of real estate and commercial real estate, skyscraper gets more and more, increasing to the demand of elevator.
The existing design of the coder axle for elevator traction machine adopts integral structure (bar portion and flange), because blank flange face is large, bar portion is elongate tapered structure, be not suitable for die forging and can only adopt open die forging, with forged flange face again after the pulling of circle material, such technics comparing is complicated, due to open die forging dimensional control low precision, cause bar portion stock left for machining very large, make the stock utilization of product very low, the stock utilization in bar portion only has 0.15, and Total Product stock utilization only has 0.3, and this design causes productive costs very high.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of coder axle for elevator traction machine, and save material and Simplified flowsheet, stock utilization is improved, and reduces productive costs.
For realizing above-mentioned object, a kind of coder axle for elevator traction machine described in the utility model, comprise bar portion and flange, described bar portion and flange are two parts, the centre of described flange is provided with step, described bar portion and flange are at described step place by being welded to connect, and described bar portion is an elongated cylinder.
Preferably, the step of described flange is three grades, is wherein positioned at middle step the highest, and the step of both sides is symmetrical centered by the step of centre, and described bar portion is welded in intermediate step by friction welding.
Preferably, the diameter of the step of described centre is identical with the diameter in bar portion.
Preferably, the other end in described bar portion is provided with attaching parts, for being connected to miscellaneous part.
Preferably, the diameter being directly less than described bar portion of described attaching parts.
Preferably, the edge of described flange is provided with projection.
The utility model beneficial effect:
The shape of the utility model to existing product designs, and it is designed to two parts, a flange and a columniform elongated shaft, such structure can Simplified flowsheet, after using raw MAT'L prtreatment respectively, adopt friction welding weld together, finally carry out fine limit work.After this design, stock utilization is improved, both can saves forging, and save raw MAT'L again, and reduce machinework productive costs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: bar portion 1, flange 2, step 3, attaching parts 4, protruding 5.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 1, the present embodiment provides a kind of coder axle for elevator traction machine, comprise bar portion 1 and flange 2, described bar portion 1 and flange 2 are two parts, the centre of described flange 2 is provided with step 3, described bar portion 1 and flange 2 are at described step 3 place by being welded to connect, and described bar portion 1 is an elongated cylinder.
As a preferred implementation, the step 3 of described flange 2 is three grades, and the step being wherein positioned at midway location is the highest, and the step of both sides is symmetrical centered by intermediate step, and described bar portion 1 is welded on middle step by friction welding.
As a preferred implementation, the diameter of the step of described centre is identical with the diameter in bar portion 1.
As a preferred implementation, the other end in described bar portion 1 is provided with attaching parts 4, for being connected to miscellaneous part.
As a preferred implementation, the diameter being directly less than described bar portion 1 of described attaching parts 4.
As a preferred implementation, the edge of described flange 2 is provided with protruding 5.
The utility model is designed to two parts, a flange and a columniform elongated shaft, and such structure can Simplified flowsheet, after using raw MAT'L prtreatment respectively, adopts friction welding weld together, finally carries out fine limit work.After this design, stock utilization is improved, the stock utilization in bar portion is increased to 0.6 by original 0.15, Total Product stock utilization is increased to 0.55 by original 0.3, this design both can save forging, saved raw MAT'L again, and reduced machinework productive costs.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
