Abstract
The utility model discloses a wrought-steel hooked-tail frame bending die, comprising an upper die, an upper die base, a lower die, a roller and pins. The roller is installed on the lower die through pins; the roller edge appropriately projects to the inner of the lower die edge; the inner of the lower die is provided with a lubricating film laminated with the inner wall of the lower die. In operation, when two sides of a hooked-tail frame slide to the lower die, the roller can rotate with the hooked-tail frame; the lubricating film has lubrication effects, which can accordingly minimize the friction between the two sides of the hooked-tail frame and the lower die when the hooked-tail frame is pressed. The utility model possesses the advantages of good hot pressing effects and small thickness deformation of frame body side plates, and can effectively avoid the hooked-tail frame from being scratched or elongated or deformed by the lower die and is convenient to demould.
Description
Technical field
The utility model relates to railway freight-car forged steel coupler yoke manufacturing process technology, is a key device in the forged steel coupler yoke process for making.
Background technology
Forged steel coupler yoke is that U-shaped parts in the rolling stock jockey see that Fig. 6 and accessories such as hitch, buffer are combined into coupler and draft gear, directly finish the transmission of longitudinal force between the vehicle.The hook tail frame that uses on the past rolling stock is a steel-casting always, because defectives such as there is pore unavoidably in steel-casting, is mingled with, shrinkage porosites, intensity is difficult to improve.Now adopt high-intensity steel alloy stocking, process brake forming then by forging, pressing, make hook tail frame material form full fibr tissue, its latent defect significantly reduces than steel-casting, and comprehensive mechanical performance improves, and its intensity and service life can significantly improve.But because be blank brake forming while hot after will forging and pressing processing, die needed can not be identical with cold stamping die, otherwise can make the distortion of framework side plate thickness big and influence quality.
The utility model content
The purpose of this utility model be for forged steel coupler yoke after forging just one-step forming, in its forging temperature, bend to U font framework along machine direction, provide that a kind of hot pressing is effective, the framework side plate thickness changes for a short time, prevents the forged steel coupler yoke bending die that framework is scratched or is elongated and deformed and is convenient in demoulding.
Forged steel coupler yoke bending die of the present utility model, its structure comprises patrix, upper bolster and lower mould part, patrix is contained in the lower end of upper bolster through connecting bolt; Wherein, lower mould part comprises counterdie, roller and bearing pin, and roller is installed on the counterdie by bearing pin, and the edge of described roller should suitably be projected in the counterdie edge, puts into a lubricating film of fitting with the counterdie inwall in described counterdie.
Described roller edge is projected into the intramarginal optimum value of counterdie and elects 2～5 millimeters as.
Described lubricant film layer is a polytetrafluoroethylplastic plastic, and the thickness of described lubricant film layer is 0.3～0.5mm.
Forged steel coupler yoke bending die of the present utility model, owing to be provided with roller and lubricating film in the counterdie inboard, make hook tail frame biside plate when slipping into counterdie, because of slipping into hook tail frame biside plate, roller rotates, and lubricating film can keep apart biside plate and counterdie, plays the effect that profit is changed and reduced friction simultaneously.The friction of framework biside plate and counterdie when slipping into can effectively prevent because frictional force is too big with the scuffing of framework biside plate or with lengthening deformation.It is effective to have hot pressing, and framework side plate thickness distortion is little, can effectively avoid framework to be scratched or is elongated and deformed and advantage such as is convenient in demoulding.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Referring to accompanying drawing 1, among the figure 1 is upper bolster, the 2nd, patrix, the 3rd, bolt, the 4th, counterdie, the 5th, roller, the 6th, bearing pin, described patrix 2 is fixedly connected on the upper bolster 1 through bolt 3, and roller 5 is installed on the counterdie 4 by bearing pin 6, the edge of roller 5 suitably should be projected in the edge of counterdie 4 during installation, in described counterdie, put into a lubricating film 10 of fitting with the counterdie inwall.This lubricant film layer is a polytetrafluoroethylplastic plastic, and the thickness of described lubricant film layer is 0.3～0.5mm.The edge of described roller 5 is projected into counterdie 4 intramarginal optimum values and elects 2～5 millimeters as.Can change different patrixes according to the hook tail frame of different model.Also can change roller 5, also replaceable in case of necessity counterdie according to the hook tail frame of different model.
During work upper bolster 1 is installed on the slide block 7 of hydraulic press, counterdie 4 is installed on the workbench 9 of hydraulic press and with its consistency from top to bottom, make patrix 2 can go deep in the middle of the counterdie 4 and make the gap between the upper and lower mould even, to forge the straight hook tail frame blank 8 in back then is placed on the counterdie 4, its outstanding afterbody is aligned, referring to Fig. 2 between both sides roller 5.Start hydraulic press and make 7 times general who has surrendered's hooks of slider of hydraulic press tail frame blank 8 be pressed into counterdie 4 along between the roller 5, the complete and counterdie applying in the hook tail frame blank bottom after making bending is referring to Fig. 3.Starting hydraulic press rises slider of hydraulic press 7, boss position on slide block drive patrix and its die holder is hooked hook tail frame blank head and is broken away from counterdie fully until hook tail frame blank bottom, referring to Fig. 4, at last hook tail frame is pulled out its fore-and-aft direction from Fig. 4 position with specific purpose tool and lie in platform and get final product, referring to Fig. 5, finish the bending work of hook tail frame.It is effective to have hot pressing, and framework side plate thickness distortion is little, can effectively avoid hook tail framework to be scratched or is elongated and deformed and advantage such as is convenient in demoulding.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
