Description
Technical field
The present invention relates to a kind of production technology of mechanical transmissioning piece, the production technology of especially a kind of sprocket wheel or ring gear.
Background technology
Sprocket wheel and ring gear are all common mechanical transmissioning pieces, extensively using with all kinds of plant equipment.In traditional mode of production, lead to
Mode frequently with forging molding is produced, and stock utilization is relatively low, and the arc flank of sprocket wheel or ring gear is easy
Burst apart, product fraction defective is of a relatively high, and mould is also easily damaged, the mold use life-span is relatively low.
In order to avoid arc flank bursts apart, Some Enterprises employ the mode repeatedly forged and produced, this production
Technique is forged each time needs to use a secondary mould, although mould is hardly damaged, but production cost is of a relatively high；Also there is part
Enterprise directly processes sprocket wheel or ring gear using numerical control machining center, and this production technology does not need usable floor area, but sets
Standby cost is relative to increase, and processing efficiency is relatively low, also results in production cost of a relatively high.
In addition, for large-scale sprocket wheel or large-scale ring gear, it is difficult to be directly processed using numerical control machining center, and use forging
When causing the mode of type to be produced, the tonnage of required forging machine is relatively large, also results in production cost of a relatively high.
In view of this, the production technology of the applicant's sprocket wheel or ring gear is conducted in-depth research, and has this case generation then.
The content of the invention
It is an object of the invention to provide a kind of product fraction defective is relatively low, die life is of a relatively high and produces
The sprocket wheel of advantage of lower cost or the production technology of ring gear.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of production technology of sprocket wheel or ring gear, comprises the following steps,
S1：Profile is cut, and thickness and the sprocket wheel thickness identical steel plate to be produced is chosen, using cutting machine in the steel
Shape cutting is carried out on plate, the sprocket wheel or the outer contour shape identical blank of ring gear for obtaining outer contour shape and being produced；
S2：Endoporus is cut, and endoporus is cut out in the center of the blank, obtains semi-finished product；
S3：The semi-finished product are forged by forging molding on forging machine, the peripheral position in the semi-finished product both sides
Place molds arc flank；
S4：Overlap processing, by the way of milling, cutting or the grinding by forging molding during the overlap that produces remove,
Obtain sprocket wheel or ring gear.
As a modification of the present invention, in step s3, while the interior hole peripheral forging molding in the semi-finished product goes out
Floor.
As a modification of the present invention, after the completion of step S3, following steps have also been carried out：
Perforation processing, processes multiple perforation on the floor by the way of turning, milling, drilling or cutting, many
Individual perforation even cloth centered on the endoporus.
As a modification of the present invention, in step S1 and step S2, it is plasma fire to cut used cutting machine
Flame cutting machine or wire cutting machine.
Above-mentioned technical proposal is used, the invention has the advantages that：
By carrying out carrying out forging molding after the tooth form of cut place again to steel plate, forging resistance is relatively small, and flash is relatively
Few, the arc flank of sprocket wheel or ring gear is difficult to burst apart, and product fraction defective is relatively low, die life is of a relatively high, institute
The forging machine tonnage needed is relatively low, and production cost is relatively low.

Embodiment
The present invention is described further for specific embodiment below in conjunction with the accompanying drawings.
The production technology that the present embodiment is provided, can be used for the production of sprocket wheel or ring gear, main due to sprocket wheel and ring gear
Difference is the difference of tooth form, is illustrated in the present embodiment by taking sprocket wheel as an example.
The production technology for the sprocket wheel that the present embodiment is provided, comprises the following steps,
S1：Profile is cut, and thickness and the sprocket wheel thickness identical steel plate to be produced is chosen, using cutting machine on steel plate
Shape cutting is carried out, the sprocket wheel or the outer contour shape identical blank of ring gear for obtaining outer contour shape and being produced, certainly,
Need to make copying template mould before shape cutting.Because blank is obtained by way of cutting steel plate, on steel plate
The production of other parts of rim charge can still be used for, compared with the production technology that conventionally employed forging molding obtains sprocket wheel, material profit
95% or so can be promoted to by 55% or so with rate, stock utilization is of a relatively high.
S2：Endoporus is cut, and cuts out the endoporus coaxially arranged with blank in the cental axial position of blank, obtain such as Fig. 1 and
Semi-finished product shown in Fig. 2.If it should be noted that the thickness of other positions of the sprocket wheel produced in addition to sprocket is identical
, then the mounting hole size that the hole size that this step is cut coordinates with sprocket wheel with power transmission shaft always, otherwise cut by this step
The hole size cut needs to be more than the mounting hole size that sprocket wheel coordinates with power transmission shaft, and material is compacted when so can be for follow-up forging
It is dynamic that space is provided, the generation of difference can also be reduced, in the present embodiment, the hole size that this step is cut needs to be more than chain
The mounting hole size that wheel coordinates with power transmission shaft.
The sequencing of this above-mentioned two step be do not have it is conditional, it might even be possible to simultaneously carry out.In addition, in the present embodiment
In, in step S1 and step S2, it is preferably plasma flame cutting machine or wire cutting machine to cut used cutting machine.
S3：Semi-finished product as shown in Figure 3 and Figure 4, are forged by forging molding on forging machine so that semi-finished product both sides
Peripheral position at mold arc flank 10, that is to say the arc flank 10 at two side position forging moldings of sprocket,
Go out floor 20 in the interior hole peripheral forging molding of semi-finished product simultaneously, the thickness of floor 20 is less than the thickness of steel plate, in this process
In, the material of the position of floor 20 is extruded so that portion of material is extruded at the position of endoporus, so that endoporus
Size reduce, form the mounting hole that sprocket wheel and power transmission shaft coordinate.
S4：Perforation processing, with reference to shown in Fig. 5, is processed on floor 20 by the way of turning, milling, drilling or cutting
Go out multiple perforation 30, multiple even cloth centered on endoporus of perforation 30.
S5：Overlap processing, by the way of milling, cutting or the grinding by forging molding during the overlap that produces remove,
Sprocket wheel as shown in Figure 5 is obtained, certainly, if necessary, the sprocket wheel obtained needs further to carry out the process such as being heat-treated well.
The present invention is described in detail above in conjunction with specific embodiment, but embodiments of the present invention and not only limited
In above-mentioned embodiment, those skilled in the art can make various modifications according to prior art to the present invention, and these are belonged to
Protection scope of the present invention.
