The utility model relates to cold extruding technique field, particularly relates to a kind of internal spline cold extrusion equipment for motor turning pump shaft.
Background technology
The feature of the pump shaft that current automobile is used is for ensureing that in part, external splines need possess axiality accurately, mach mode is mostly adopted to carry out the interior external splines of machining shaft in the prior art, but the time that machined consumes is longer, processing inconvenience, and the raw material consumed are also larger, production cost is high, in addition machined is owing to being fixedly clamped by artificial location, therefore the axiality requirement of interior external splines is a difficult problem to adopt machined to ensure, and in prior art, adopt cold extruding technique to carry out the equipment of the interior external splines of machining shaft, its structure is all more complicated, and part need be taken out repeatedly, load the processing carrying out interior external splines successively, processing method is more complicated, axiality is also poor.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of internal spline cold extrusion equipment for motor turning pump shaft, structure is simple, easy to operate, and can raw material be saved, reduce production cost, the axiality of part internal spline and cylindrical can also be improved simultaneously, for rear road extruding external splines saves the plenty of time, increase work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of internal spline cold extrusion equipment for motor turning pump shaft, be made up of hydraulic press and mould, described mould comprises: upper die and lower die, described patrix is arranged on the upper workbench of hydraulic press, and the below of described patrix is provided with the internal spline drift matched with inner bore of part, described counterdie is arranged on the lower workbench of hydraulic press, and the center of described counterdie offers the die cavity matched with part outer, the center of described internal spline drift and described die cavity on the same line.
In the utility model preferred embodiment, the mold cavity bottoms of described counterdie is provided with padded cover.
In the utility model preferred embodiment, the below of described counterdie is also provided with parallels and push rod, and described push rod penetrates described parallels and is connected with described padded cover.
In the utility model preferred embodiment, the outside diameter of described push rod is greater than the interior circular diameter of described padded cover.
In the utility model preferred embodiment, on described hydraulic press, the stroke of workbench and the processing length of part match.
In the utility model preferred embodiment, described internal spline drift comprises: the guide pad be fixedly connected with and forming blocks, and the junction of described guide pad and described forming blocks exists radian.
The beneficial effects of the utility model are: the utility model is used for the internal spline cold extrusion equipment of motor turning pump shaft, be made up of hydraulic press and mould, mould comprises: upper die and lower die, and the center being arranged on the internal spline drift below patrix be positioned at counterdie die cavity be centrally located on same straight line, adopt disposable cold extrusion forming simultaneously, can ensure that the cylindrical of processed internal spline and part has higher axiality, overall structure is simple, easy to process, can a large amount of raw material be saved compared to machining technique, lower production cost.
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 utility model;
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 utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model embodiment 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.
The utility model discloses a kind of internal spline cold extrusion equipment for motor turning pump shaft, and 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 embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
