Abstract
The invention relates to a device for bending and shaping a coupler yoke in a one-step way. The device comprises a plurality of hydraulic cylinders, a lower mold and a convex mold, wherein the lower mold is in a three-section type, the two sides of the lower mold can be extruded in an obliquely upward way by the hydraulic cylinder B and the hydraulic cylinder C to form a U shape, and a groove matched with a blank of the coupler yoke is arranged on the upper surface of the lower mold; the convex mold is connected with a pressure head of the hydraulic cylinder A which is positioned right above the lower mold. The device has the advantages that the bending and the shaping are completed in a one-step way, the time is short, insufficient deformation caused by the low temperature of the blank of the coupler yoke is prevented, and the improvement of the cost generated by the second heating is avoided; then, after the bending and the shaping are finished, a trolley plate is formed into an oblique surface by the hydraulic cylinder H on a paladin trolley, meanwhile, the coupler yoke is lightly pushed by the hydraulic cylinder G at the back of the coupler yoke to be against a plate trailer, and then the hydraulic cylinder H is put down, so that potential safety hazards during manual operation are avoided.
Description
Technical field
The present invention relates to a kind of hook tail frame bend molding apparatus, especially relate to the devices and methods therefor that the brake forming of a kind of hook tail frame settles at one go.
Background technology
Hook tail frame is the strength member that a kind of railway freight-car is used, and hook tail frame is to be U-shaped mount structure.Existing hook tail frame is turnover panel moulding manufacture method, normal conditions are at high temperature, first the part in the middle of secured blank, pass through again special forcing press from two curved plates, make it be U-shaped, after to be formed, carry out again shaping, thisly form several shortcomings, first this method is difficult to avoid the distortion of steel plate, it is U-shaped straight position, both sides mutual dislocation, and U-shaped straight portion also can bend or warpage, thereby need to carry out further shaping, expend time in longer, conventionally shaping process also needs to reheat, therefore production cost increases greatly, on the other hand, with the method and the special corresponding forcing press of device needs, this also can cause the raising of production cost.
Also have in addition a kind of horizontal form mode, if the patent No. is CN102389913A and CN202343640U, its method is to utilize the propulsion cylinder of both sides and behind horizontal mode to suppress hook tail frame, and hook tail frame blank is pressed into U-shaped.Although the method is simple, without two procedures, is easy to occur deformation in the time of the brake forming of hook tail frame blank, causes the shape of finished product not reach requirement.
In addition, also has a kind of vertical forming mode, if the patent No. is CN100460101C, its method is: the hook tail frame blank just having forged is had to certain waste heat or the hook tail frame blank through heating, be placed on bending on forming machine, with forcing press drive punch stress on hook tail frame blank, make hook tail frame blank bending and enter the recess of forming frame body, until hook tail frame blank and die are close to, simultaneously, the framework plate that makes to be arranged at least three pairs of pressure roller compacting hook tail frame blanks on forming machine support body by controlled pressure machine makes framework plate straight, thereby make framework plate be close to punch, make axially to suppress to vertical running roller with pressure roller shaft the limit of hook tail circle body plate by controlled pressure machine, the framework plate on both sides is not distorted, finally remove press pressure, the demoulding, the shortcoming that this hook tail frame shaped device exists is that the time uncertainty of running roller compacting is many, be easy to because overlong time causes the shape of hook tail frame blank can not be guaranteed, may there is larger deformation, next is exactly that forcing press and running roller all need special, so improved to a great extent production cost.
Therefore be just necessary to develop the devices and methods therefor that a kind of production cost is low and can make the brake forming of hook tail frame settle at one go, do not find and the same or analogous devices and methods therefor of the present invention through retrieval.
