Abstract
The utility model discloses an engine connecting rod preforming cracking device. The engine connecting rod preforming cracking device can apply pressure to a V-shaped groove in an engine connecting rod preforming piece; machining is convenient due to the fact that the pressure is applied in the groove to form fractured surfaces; the number of machining procedures is small; at the time of secondary machining, the number of the machining procedures can be effectively reduced, the two surfaces are matched easily after the machining, and therefore the purposes of saving time, labor and resources are achieved.
Description
Technical field
The utility model relates to a kind of engine link preformed cracker.
Background technology
It is reported that the auto output of China in 2010 is about 1,400 ten thousand, traditional common forging and stamping and the machining process processing of the general employing of the engine link of domestic automobile, for improving engine performance, some automobile production producer adopts the sinter soging connecting rod from external import, substitutes existing product.
Therefore, the engine link of domestic produced in conventional processes has been difficult to meet high-quality in the industrial production such as current automobile, high accuracy, high efficiency, low consumption, requirement that cost is low.
In last century, Germany and the U.S. forge and to begin one's study iron powder, succeed in developing a kind of novel metal forming technique power forging, are swaged into first the parts such as connecting rod, have now in connecting rod two ends are arranged, and a tradesman generally end that termination is larger is called stub end.
The power forging technology be conventional powder metallurgical technique and precision forging organically combine and of growing up have much the market competitiveness less, without the cutting metal processing method; take metal dust as raw material; through the preformation compacting; in protective atmosphere, carry out heat-agglomerating and as main blank; then forging molding and realizing without the burr precision die forging once on forcing press, form and common forge piece equal densities, complex-shaped net-size forging.The advantage of existing powder metallurgy formation better performances, can bring into play again the characteristics that forging this case effectively change metal material tissue and performance effect, makes powder metallurgy and Forging Technology obtain new breakthrough on producing.
The engine link forged piece preformed piece of manufacturing at present, in big end end inner circle, not being provided with " V " type breach, is to wait instrument to cut big end end use saw when manufacturing engine link, the face after reprocessing is cut, after this processing, face is too smooth, easily dislocation, when in use, two faces are not easy to coincide, this engine link forged piece preformed piece in processing again, time-consuming also effort, and moulding is bad.
Summary of the invention
The utility model is for above problem, a kind of cracker of engine link preformed member is provided, because the connecting rod preformed member is provided with the V-shaped groove body in blank, the taper press rods formation plane of disruption of exerting pressure in groove by crank bore, thus reach the purpose of cracking connecting-rod major part.
For achieving the above object, the utility model adopts following technological means:
A kind of engine link preformed cracker, comprise that be used to carrying the horizontal stand of engine link, support is provided with the through hole corresponding with engine connecting rod big end end circular hole, and the top of horizontal stand is provided with a taper press rods.
Further, described support upper surface is provided with the depressed area face corresponding with the engine link contact-making surface.
Further, described horizontal stand stub end both sides are provided with wall supporting.
Further, a side of the stub end of described horizontal stand is provided with the soft bearing capacity district of arc section after the carrying cracking.
Further, the corresponding engine link body position of described horizontal stand place is provided with the clamping piece for the clip engine link.
Operation principle of the present utility model and the course of work are as follows:
Adopt technique scheme, hole circle is the design of " V " type breach in the big end end, and under the effect of taper press rods, big end is cleaved to come.Big end end after decomposition, the fracture morphology uniformity, extraordinary polarization is arranged when assembling, except hold-down screw, without any machined, can effectively reduce manufacturing procedure, save the process equipment investment, improve stock utilization, reach time saving and energy saving, economize on resources, the purpose that significantly reduces costs.
The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, the accompanying drawing that the following describes is only some embodiment that put down in writing in the application, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing;
Fig. 1 is the utility model structural representation.
The specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Based on the embodiment in the application, those of ordinary skills are not making under the creative work prerequisite the every other embodiment that obtains, and all should belong to the scope of the application's protection.
As shown in Figure 1, a kind of engine link preformed cracker, comprise the horizontal stand 1 be used to carrying engine link, and support 1 is provided with the through hole 2 corresponding with engine connecting rod big end end circular hole, and the top of horizontal stand 1 is provided with a taper press rods 3.
Because the side of engine link is provided with arris, in cracking, there will be and slide or arris is caused to certain breakage, therefore in the support upper surface, be provided with the depressed area corresponding with the engine link contact-making surface 4, during use, engine link can be placed in to depressed area 4, can play anti-skidding and reduce the breakage to arris.
During engine link, under the effect of powerful external force, the stub end of engine link may outwards eject, be unfavorable for section and inner arc surface, for the anti-phenomenon of planting here, horizontal stand stub end both sides are provided with wall supporting, and a side of the stub end of horizontal stand is provided with the soft bearing capacity district of arc section after the carrying cracking.
The corresponding engine link body position of described horizontal stand 1 place is provided with the clamping piece for the clip engine link.
During use, engine link is placed in to depressed area 4, with clamping piece clip engine link body, then taper press rods 3 moves downward, and stub end is from the cracking of V-arrangement opening part.
The above is only the application's preferred embodiment, makes those skilled in the art can understand or realize the application.Multiple modification to these embodiment will be apparent to one skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the application's spirit or scope, realization in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
