Model utility content
The technical problems to be solved in the utility model is: the problem existing for prior art, a kind of bent axle car blank structure is provided, and in the time that car base is extruded moulding, avoid the connecting rod neck position of car base to occur interlayer, the mass defect such as folding.
The technical problems to be solved in the utility model realizes by the following technical solutions: a kind of bent axle car blank structure, in car base main body, be provided with connecting rod neck, described connecting rod neck is arranged between two sections of adjacent car base main bodys, the end face that car base main body combines with connecting rod neck is processed with inclination ring surface, described inclination ring surface upwards extends from the junction of connecting rod neck and car base main body, and and car base main body outer surface between angle be acute angle.
Further, described connecting rod neck two ends and be positioned at inclination ring surface in car base main body and the outer surface of connecting rod neck forms " V " font groove jointly." V " font groove contributes to eliminate car base and is extruded and occurs interlayer, the mass defect such as folding after moulding in connecting rod neck both sides, improves product quality.
Further, the angle between described inclination ring surface and car base main body outer surface is 30 degree-60 degree.The chamfering at the step place, connecting rod neck both sides of this car base main body has leading role, and in hydraulic press forming process, matched moulds is convenient, quick.
Preferably, the angle between described inclination ring surface and car base main body outer surface is 45 degree.The 45 degree chamferings at this place had both had leading role, can farthest reduce again the cutter loss in car base main body course of working.
Further, described car base main body is to adopt forged steel to make.Forged steel shaping workpiece can improve organization internal structure, and good mechanical property can bear large impact force action.
Further, described car base main body adopts structural carbon steel or Alloy Constructional Steel to make.Workpiece, owing to wherein containing the alloying element of variety classes and quantity, has the properties such as higher intensity, toughness, wear resistance.
Compared with prior art, the beneficial effects of the utility model are: because the end face combining with connecting rod neck in car base main body is processed with inclination ring surface, and the angle between described inclination ring surface and car base main body outer surface is the chamfering of 30 degree-60 degree, the leading role that utilizes this chamfering to have, can make the matched moulds of car base main body in hydraulic press machine shaping process convenient, quick, and eliminate connecting rod neck both sides and in course of working, occur interlayer, the mass defect such as folding, be conducive to improving product quality, eliminate product and reprocess the cost waste bringing; Meanwhile, the said structure of this car base main body also helps and reduces the cutter loss that car base main body adds man-hour, cuts down finished cost.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, a kind of bent axle car blank structure, in car base main body 1, be provided with connecting rod neck 2, described connecting rod neck 2 is arranged between two sections of adjacent car base main bodys 1, the end face that car base main body 1 combines with connecting rod neck 2 is processed with inclination ring surface 3, and connecting rod neck 2 two ends and the inclination ring surface 3 being positioned in car base main body 1 form " V " font groove jointly with the outer surface of connecting rod neck 2; Described inclination ring surface 3 upwards extends from connecting rod neck 2 and the junction of car base main body 1, and and angle between car base main body 1 outer surface is acute angle, generally, angle between described inclination ring surface 3 and car base main body 1 outer surface is 30 degree-60 degree, can be 30 degree, 35 degree, 40 degree, 45 degree, 50 degree, 55 degree, 60 degree, or 30 degree other angle values within the scope of-60 degree, concrete value is determined according to actual processing request and the usage requirement of car base main body.Certain concrete chamfering that this place 30 is spent between-60 degree has leading role, and utilizing in hydraulic press processing cart base main body 1 forming process, matched moulds is convenient, quick; In addition, described " V " font groove also contributes to eliminate car base main body 1 and is extruded and occurs interlayer, the mass defect such as folding after moulding in connecting rod neck 2 both sides, thereby is conducive to improve product quality, has improved car base and has opened grade efficiency and crankshaft forming efficiency.
As one preferred embodiment, angle between above-mentioned inclination ring surface 3 and car base main body 1 outer surface is 45 degree, spend chamfering and had both had leading role at this place 45, facilitate the matched moulds in hydraulic press processing cart base main body 1 forming process convenient, quick, and this place 45 spend chamfering can also make machining tool in car base main body 1 course of working lateral stressed, longitudinal stress is basic identical, thereby contribute to farthest to reduce the cutter loss in car base main body 1 course of working, and then reduced manufacturing cost.
