Abstract
The invention relates to a method for processing a camshaft spline of an automotive brake and a device therefor. The device comprises a squeeze roller I, a squeeze roller II, a squeeze roller base, a limit device, an adjusting device, a driving mechanism, a squeeze roller position adjusting mechanism, a frame and a wear-resisting bearing, wherein the squeeze roller base is provided with the limit device and the adjusting device and is also provided with the squeeze roller position adjusting mechanism; the squeeze roller I and the squeeze roller II are connected with the driving mechanism; and the squeeze roller base, the driving mechanism and the wear-resisting bearing are arranged on the frame. By adopting the two squeeze rollers for rolling, the tooth shape of the processed spline is consistent, and the surface density degree after processing is obviously strengthened, thereby greatly improving the quality of the processed product. As the blank is preheated before extrusion processing, the extrusion is carried out under certain temperature, so that the extrusion is easy, and the performance of the processed product is reliable. The extrusion process is adopted for processing, so as to improve the working efficiency greatly.
Description
Technical field
The present invention relates to a kind of processing method of auto parts and components, specifically a kind of processing method and equipment of automotive brake camshaft spline.
Background technology
Relevant by retrieval patent documentation, present processing method and the equipment that does not retrieve a kind of automotive brake camshaft spline identical as yet with structure of the present invention.The making of existing automobile camshaft spline, the general spline cutter that adopts carries out Milling Process on production miller, to make the spline that processes exist fish scale shape tool marks comparatively serious owing to the reason of its processing method, and cutting place burr is more obvious, phenomenons such as surface roughness is poor, the reason of milling cutter position degree and workpiece relative position adjusting is offset in process easily in addition, causes the spline angular deviation bigger.And, cause that easily assembling is not in place because long excessive circular arc, should appear at length direction milling spline end in milling cutter.So be necessary the processing method of existing automotive brake camshaft is improved, to improve the quality of product.
Summary of the invention
The objective of the invention is to provide a kind of employing to add hot extrusion technique, make the finished product that squeezes out have smooth surface, function admirable, and the processing method of a kind of automotive brake camshaft spline that can enhance productivity greatly.
Another object of the present invention is that the equipment of realizing said method will be provided.
To achieve these goals, the present invention is by the following technical solutions:
A kind of processing method of automotive brake camshaft spline may further comprise the steps:
(1) splined shaft axle head to be processed is worked into the reservation size;
(2) workpiece part to be processed is heated to 250 ℃～300 ℃;
(3) workpiece to be processed that will heat is filled in the wear-resisting supporting;
(4) splined shaft to be processed is held out against by adjusting device;
(5) regulate the compression roller spacing;
(6) starting device, and two compression rollers are progressively approaching to splined shaft to be processed under the driving of compression roller position adjusting mechanism, push;
(7) under the roll extrusion of two compression rollers, splined shaft is squeezed to required spline size, gets finished product.
A kind of process equipment of above-mentioned automotive brake camshaft spline, comprise compression roller I, compression roller II, compression roller support, stopping means, adjusting device, driving mechanism, compression roller position adjusting mechanism, frame, wear-resisting supporting, it is characterized in that: on the compression roller support, be provided with stopping means, adjusting device, be provided with the compression roller position adjusting mechanism on the compression roller support, described compression roller I, compression roller II are connected with driving mechanism; Compression roller support, driving mechanism, wear-resisting supporting are arranged on the frame.
Described its squeegee roller of compression roller I is and camshaft spline length and the identical squeegee roller of profile of tooth.
Described its squeegee roller of compression roller II is and camshaft spline length and the identical squeegee roller of profile of tooth.
Described compression roller position adjusting mechanism is the governor motion that a screw mandrel drives.
The squeegee roller of described compression roller I is the wheel body that high strength roll extrusion material is made.
The squeegee roller of described compression roller II is the wheel body that high strength roll extrusion material is made.
Advantage of the present invention is: owing to take two compression rollers to carry out rolling and processing, thus make the spline teeth unanimity after the processing, and obviously strengthen through processing rear surface compactness extent, improved the quality of processing back product greatly; Owing to before extrusion process, earlier blank is preheated, thereby extruding is carried out at a certain temperature, make extruding easily, make the properties of product that process reliable; Owing to adopt extrusion process to process, and the adjusting of compression roller regulates by position adjusting mechanism, thereby makes extruding rapidly, improved work efficiency greatly; Because rational in infrastructure, technology is advanced, simple to operate, so very big practical and popularizing value is arranged.
