Description
Technical field
The present invention relates to knuckle and manufacture equipment, be specifically related to a kind of major axis class knuckle Correction Die。
Background technology
Major axis class knuckle needs when manufacturing to be corrected, and timing needs to utilize Correction Die to carry out。Traditional Correction Die is made up of upper die and lower die, picking and placeing for the ease of workpiece, the axle head of knuckle is placed on mould place, axle head is all exposed to outside mould at the position of timing more than 2/3rds, when having corrected, axle head can bending phenomenon occurs, namely axle head is overproof relative to the perpendicularity in face, chassis, causes that waste product occurs, is substantially reduced benefit。
Summary of the invention
For the deficiencies in the prior art, the invention provides that a kind of cost is little, a kind of major axis novel Correction Die of class knuckle of simple in construction, it is possible to effectively stop the generation of waste product, increase the benefit。
The present invention is achieved by the following technical solutions:
A kind of major axis novel Correction Die of class knuckle, described major axis class knuckle includes flange, is arranged on the axle head on the upside of flange and is arranged on the lever arm on the downside of flange, described Correction Die includes counterdie, upper mould and bushing, described counterdie includes the lower impressions of companion flange bottom and lever arm, described upper mould includes the upper impression of companion flange top and axle head, upper impression includes the axis hole passed for axle head, described bushing it is located on axis hole, is provided with the trepanning connected with axis hole in bushing to be entangled by the axle head passed from axis hole。
As preferred embodiment, the uper side surface of described upper mould is provided with shape and the bushing groove mated in axis hole periphery, described bushing is flush-mounted in groove。
As preferred embodiment, between described counterdie and upper mould, it is provided with the fastener of fastening mutually。
As preferred embodiment, between described bushing trepanning and axle head, leave gap。
The invention has the beneficial effects as follows: the axle head of knuckle can effectively be fixed by the bushing of the present invention; the position of timing axle head can stably keep, and can be protected, it is ensured that axle head does not have buckling phenomenon; stop the generation of waste product in trimming process, increased the benefit；The present invention makes split-type structural, effectively reduces the mould material weight of upper mould, reduces die cost。
Accompanying drawing explanation
Fig. 1 is the structure chart of the present invention。
Description of symbols: 1-counterdie, the upper mould of 2-, 3-is bushing, 4-lower impressions, 5-upper impression, 6-axis hole, 7-trepanning, 8-groove。
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
The Correction Die of the present invention is mainly used in major axis class knuckle workpiece is corrected, and plays fixing effect at timing。During use, major axis class knuckle is placed in mould and is corrected。So-called major axis class knuckle is overall structure, and including flange, axle head and lever arm etc., axle head is arranged on the upside of flange, and lever arm is arranged on the downside of flange, and axle head is slim-lined construction。
Based on above slewing journal structure, the Correction Die of the present invention is made up of three split type parts, including counterdie 1, upper mould 2 and bushing 3。
Specifically, as it is shown in figure 1, counterdie 1 entirety is generally square structure, it is provided with lower impressions 4, and the structure that the shape of this lower impressions 4 forms with flange bottom and lever arm is corresponding。The square structure that upper mould 2 is generally corresponding with counterdie 1, it is provided with upper impression 5, and the structure that the shape of upper impression 5 forms with flange top and axle head is corresponding, and upper impression 5 includes the axis hole 6 passed for axle head。Bushing 3 are located on axis hole 6, are provided with the trepanning 7 connected with axis hole 6 to be entangled by the axle head passed from axis hole in bushing 3。
So that the position of bushing 3 is more stable, the uper side surface of upper mould 2 is provided with, in axis hole 6 periphery, the groove 8 that shape is mated with bushing 3, and during use, bushing 3 are flush-mounted in groove 8。
It addition, so that upper mould 2 is loaded on position stability during counterdie 1, be preferably provided with the fastener of fastening mutually between counterdie 1 and upper mould 2。
When the present invention specifically applies, first counterdie 1 is placed on supporting platform, knuckle is provided with in the lower impressions 4 that the side of lever arm loads counterdie 1 down, then upper mould 2 is directed at position and buckles, upper impression 5 is placed on knuckle, and the axle head of knuckle is passed from axis hole 6。Then it is set on axle head by bushing 3 so that the bottom of bushing 3 is inserted in the groove 8 on upper mould 2, carries out position and fixes。After completing above step, knuckle just can be carried out good spacing by Correction Die, thus carrying out next step correction work。When specifically applying, in order to avoid axle head is impaired, between trepanning 7 and the axle head of bushing 3, generally leave gap。
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention。
