Abstract
Reverse arm mould of bending, including the base with establish the clamp plate in base top, it is equipped with a plurality of spacing posts to distribute on base and the clamp plate, the spiro union has thick an of mound on the terminal surface of base, the thick seat of mound is done including blank socket and supporting seat, and the blank socket adopts detachable threaded connection with the supporting seat, is equipped with in the blank socket and twists reverse arm microcephaly jack, and the axis of this jack and the contained angle a between the base end face are less than 80 degrees, the utility model discloses can improve and twist reverse the arm in the yield of in -process of bending to simple structure practices thrift the electric energy.
Description
Technical field
The utility model relates to a kind of Bending Mould, particularly reverse arm Bending Mould.
Background technology
Reverse arm is the anti-inclined to one side important spare part of motor-car, and reverse arm adopts forge piece and has better mechanical property than adopting cast member, has more ensured the high-speed cruising of motor-car.
Reverse arm is by 120 millimeters of diameters at forging process now, the cylindrical blank that weight is 25 kilograms, first adopt pneumatic hammer by one end pulling of blank, the similar multidiameter of blank shape (as shown in Figure 7) after pulling, again multidiameter blank is placed on and on Bending Mould, carries out bending (as illustrated in Figures 5 and 6), after blank bending, then by one end thinner blank flatten, correction, machined and polishing, make finished product reverse arm (as shown in Figure 8).
But because one end diameter that blank is thicker is excessive; in the process of bending, blank often can be not in place in the A point place's bending as in Fig. 5; cause the B point place of the major part lower end of finished product reverse arm (as shown in Figure 8) to be not fully filled, and then reduced yield rate, current settling mode is to adopt to strengthen billet weight; in the time that forging blank is placed; by blank, deliberately toward B point inclined position, although yield rate has improved, it is not very obvious improving; and need to strengthen billet weight, improve production cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide reverse arm Bending Mould, can improve the yield rate of reverse arm in Forging Process, and simple in structure, saves electric energy.
In order to address the above problem, the technical solution of the utility model is: reverse arm Bending Mould, comprise base and the pressing plate that is located at base top, on base and pressing plate, be distributed with multiple limited posts, on the end face of base, be bolted with the thick seat of a pier, the thick seat of described pier does and comprises blank socket and supporting seat, and blank socket adopts detachable being threaded with supporting seat, in blank socket, be provided with reverse arm microcephaly jack, the angle a between the axis of this jack and base end face is less than 80 degree.
The beneficial effects of the utility model are: one end thinner reverse arm is inserted in jack, then working pressure machine hits one end thicker reverse arm downwards by pressing plate, make the material at B point place in Fig. 7 very sufficient, when forging, reduce the probability that in Fig. 8, B point place is not fully filled, improve yield rate, reduced production cost.

Detailed description of the invention
For the technological progress that those skilled in the art's the utility model easier to understand does prior art, before the utility model is elaborated, first prior art is described further.
Reverse arm is by 120 millimeters of diameters at forging process now, the cylindrical blank that weight is 25 kilograms, first adopt pneumatic hammer by one end pulling of blank, the similar multidiameter of blank shape (shape as shown in Figure 7) after pulling, again multidiameter blank is placed on and on Bending Mould, carries out bending (as illustrated in Figures 5 and 6), after blank bending, then by one end thinner blank flatten, correction, machined and polishing, make finished product reverse arm (as shown in Figure 8).
But because one end diameter that blank is thicker is excessive, in the process of bending, blank often can be not in place in the A point place's bending as in Fig. 5, causing the B point of the major part lower end of finished product reverse arm (as shown in FIG. 7 and 8) to be in A point place is not fully filled, the B point place of the reverse arm of blank shown in Fig. 7 is the B point position of finished product reverse arm in Fig. 8 after bending, and then reduce yield rate, current settling mode is to adopt to strengthen billet weight, in the time that forging blank is placed, by deliberately past B point inclined position of blank, although yield rate has improved, but it is not very obvious improving, and need to strengthen billet weight, improve production cost.
Below the utility model is elaborated, as shown in Fig. 1 to 4: reverse arm Bending Mould, comprise base 1 and the pressing plate 2 that is located at base 1 top, on base 1 and pressing plate 2, be distributed with multiple limited posts 3, on the end face of base 1, be bolted with the thick seat of a pier, the thick seat of described pier does and comprises blank socket 5 and supporting seat 4, blank socket 5 adopts detachable being threaded with supporting seat 4, in blank socket 5, be provided with reverse arm microcephaly jack 51, the angle a between the axis of this jack 51 and base 1 end face is less than 80 degree.
One end thinner reverse arm is inserted in jack 51, then working pressure machine hits one end thicker reverse arm blank 6 downwards by pressing plate 2, the strike point of application is arranged in the end (the F point place of Fig. 3) of one end that reverse arm blank 6 is thicker, the fulcrum of reverse arm blank 6 bendings is arranged in the position (the D point place of Fig. 3) that one end that this blank is thicker combines with thinner one end, reverse arm blank 6 is in bending process, the reverse arm blank 6 at B point place can too much not the pushing and attenuate to blank two ends because of deformation, thereby make as Fig. 3, the blank abundance at B point place in Fig. 7 or Fig. 8, B point place reverse arm blank 6 insufficient technological deficiencies are solved.
And be as fulcrum, blank to be carried out to bending as the two ends of the point of application, reverse arm blank using the E point place in Fig. 5 by contour plate by the pressing plate 2 in Fig. 5 or 6 when reverse arm blank bending in prior art, cause reverse arm blank in BENDING PROCESS to be attenuated as two ends extruding by the point of application, cause the blank at B point place inadequate.
Therefore use the utility model can effectively improve the yield rate in reverse arm bending production, reduce production costs.
