Abstract
The invention discloses a cold extruding device used for internal splines of steering pump shafts of automobiles. The cold extruding device is composed of a hydraulic machine and a mold. The mold comprises an upper mold body and a lower mold body. The upper mold body is installed on an upper working platform of the hydraulic machine. An internal spline puncher pin matched with inner holes of parts is installed below the upper mold body. The lower mold body is installed on a lower working platform of the hydraulic machine. A mold cavity matched with outer circles of the parts is formed in the center of the lower mold body. The center of the internal spline puncher pin and the center of the mold cavity are located on the same straight line. In the manner, the cold extruding device is simple in structure and convenient to operate; in addition, raw materials can be saved, and the production cost can be reduced; and meanwhile the concentricity of the internal splines of the parts and the outer circles of the parts can be improved, a large amount of time can be saved for follow-up external spline extruding, and the working efficiency can be improved.

Accompanying drawing explanation
Fig. 1 is a kind of internal spline cold extrusion equipment structural representation in a preferred embodiment for motor turning pump shaft of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, patrix, and 2, counterdie, 3, internal spline drift, 4, die cavity, 5, part, 6, padded cover, 7, parallels, 8, push rod, 31, soon shaping, 32, guide pad.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of internal spline cold extrusion equipment for motor turning pump shaft, be made up of hydraulic press and mould, described mould comprises: patrix 1 and counterdie 2, described patrix 1 is arranged on the upper workbench of hydraulic press, and the below of described patrix 1 is provided with the internal spline drift 3 matched with part 5 endoporus, described counterdie 2 is arranged on the lower workbench of hydraulic press, and the center of described counterdie 2 offers the die cavity 4 matched with part 5 cylindrical, the center of described internal spline drift 3 and described die cavity 4 on the same line, on described hydraulic press, the stroke of workbench and the processing length of part 5 match.
Wherein, padded cover 6 is provided with bottom the die cavity 4 of described counterdie 2, the padded cover 6 of differing heights can be selected according to different part dimension, thus ensure that the internal spline of part 5 can be completely extruded, expand mould to the scope of application of different size part, can prevent push rod 8 from directly contacting with part 5 when taking out part 5, part of damage simultaneously.
The below of described counterdie 2 is also provided with parallels 7 and push rod 8, and described push rod 8 penetrates described parallels 7 and is connected with described padded cover 6, after machining, can be taken out by part more easily by push rod.
Described internal spline drift 3 comprises: the guide pad 32 be fixedly connected with and forming blocks 31, there is radian in the junction of described guide pad 32 and described forming blocks 31, can convenient forming blocks 31 enter mold cavity and carry out internal spline extruding after guide pad 32 enter inner bore of part.
Present invention is disclosed a kind of internal spline cold extrusion equipment for motor turning pump shaft, its course of work is:
Patrix 1, counterdie 2 installation and debugging are good, that is: internal spline drift 3 and counterdie die cavity 4 be centrally located at same straight line, use parallels 7 that the processing length of the stroke of workbench on hydraulic press and part 5 is matched below counterdie 2, bottom counterdie 2 die cavity 4, put into padded cover 6 again, the die cavity 4 of counterdie 2 put into by part.Like this when patrix 1 is expressed to certain position downwards with internal spline drift 3, the guide pad 32 of internal spline drift 3 is introduced into part 5 endoporus, patrix 1 continues downward straightening to the forming blocks 31 of internal spline drift and enters inner bore of part, because part 5 cylindrical cannot stretch in the die cavity 4 of counterdie 2, inner bore of part starts plastic deformation occurs, thus forms internal spline.Terminate when being expressed to stroke, the mode utilizing push rod 8 to push up padded cover 6 ejects part.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
