Abstract
The present invention relates to the machining process of spindle, including upper spindle and central shaft, specially for castor. The machining process with wire as material includes extrusion at two ends to reduce diameter, cold forging to form notch, bevel and shaft, cutting extrusion with the mold with shape edge to form the shaft with fluke and round corner. The said process has less production steps, short production period, high production efficiency, low material consumption and low production cost.
Description
Technical field
This relates to the universal wheel accessory, especially a kind of processing method of spindle specially for castor.
Background technology
Upper spindle and central shaft are the important accessories on the universal wheel, and its production technology directly has influence on production efficiency and production cost.Existing universal wheel axle forges axis body and each several part size and profile with cold forging machine earlier, makes the groove at two ends again by machined into, that is to say that producing an axle needs three process.Because this kind processing method needs to be shaped with lathe car system axle, its production process certainly leads to a large amount of iron filings, not only exists raw materials consumption many, exists the production cycle long simultaneously, complex process, deficiencies such as inefficiency.
Summary of the invention
The object of the present invention is to provide a kind of technology simple, save raw material, reduce production costs, shorten the production cycle, the processing method of the spindle specially for castor of enhancing productivity.
The objective of the invention is to be achieved by the following scheme, form by upper spindle and central shaft, it is characterized in that: get equal wire rod, two ends adopt extrusion to reduce the line footpath, utilize cold forging machine to forge out footpath and groove inclined-plane and axis body required size at the bottom of the required groove in axle two ends, utilize half sharp arm of angle chamfered edge extruding of mould again, make the wire rod two ends form overhead kick body and R angle.
The invention has the advantages that: on the basis in function of use that does not change original product and service life,, whole axle only just can be finished in process of production through cold forging one procedure by changing the processing method of product.Thereby reached economical with materials, reduced production costs, reduced production process, shortened the production cycle, the purpose of enhancing productivity.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described.
Fig. 1 is a upper spindle structural representation of the present invention;
Fig. 2 is a center spindle structure schematic diagram of the present invention;
Fig. 3 is upper spindle processing schematic diagram;
Fig. 4 is central shaft processing schematic diagram.
The specific embodiment
As shown in figs. 1 and 3: be the upper spindle structural representation, constitute by the strip axis body, its processing method is: get equal wire rod, two ends adopt squeezing to reduce the line footpath, utilize cold forging machine to forge out footpath 1,2 and groove inclined- plane 5,6 and axis body required size at the bottom of the required groove in upper spindle two ends, utilize half sharp angle 10 limit chamfered edge extruding of mould 9 again, make the wire rod two ends form overhead kick body 3,4 and R angle 7,8.The present invention can make whole upper spindle only finish through cold forging one procedure in process of production, and production efficiency can improve more than 8-12 times.
Shown in Fig. 2 and 4: be the structural representation of central shaft, its processing method is identical with upper spindle, does not repeat them here.
Claims (1)
1, a kind of processing method of spindle specially for castor, comprise upper spindle and central shaft, it is characterized in that: get equal wire rod, two ends adopt extrusion to reduce the line footpath, utilize cold forging machine to forge out footpath (1,2) and groove inclined-plane (5,6) and axis body required size at the bottom of the required groove in axle two ends, utilize half limit, sharp angle (10) chamfered edge extruding of mould (9) again, make the wire rod two ends form overhead kick body (3,4) and R angle (7,8).
