Abstract
The utility model relates to a forge forming device for a thick-walled tapered hollow tube, which comprises an upper die seat, a lower die seat and guide posts, a tapered upper arc-shaped groove is formed at the bottom of the upper die seat, a lower arc-shaped groove which is identical in taper to the upper arc-shaped groove is formed at the top of the lower die seat, the groove depth H2 of the lower arc-shaped groove on the lower die seat is 1.5 to 2 times the groove depth H1 of the upper arc-shaped groove of the upper die seat, at least two guide posts are fixed on the lower die seat, and guide holes on the upper die seat are sleeved on the guide posts respectively and can conduct relative movement. The forge forming device for the thick-walled tapered hollow tube reduces the production cost and increases the percentage of tapered hollow tube finished products.
Description
Technical field
The utility model relates to a kind of forging and molding device of heavy wall taper hollow pipe, belongs to the taper hollow pipe manufacturing technology field of seamless steel pipe.
Background technology
For the taper hollow pipe mostly is to make through crimp through diel with seamless hollow pipe; and this diel is made up of last mold mechanism and following mold mechanism; last mold mechanism is connected on the pressure head of press; following mold mechanism then is installed on the workbench of press; mold mechanism is provided with the portlet support column that supports and the periphery that is positioned at support column of taper hollow pipe are pushed the tapered punch that makes its plastic deformation to hollow pipe on it; following mold mechanism is provided with the following holder that hollow pipe is carried out clamping and positioning; hollow pipe is clipped in down on the holder; in the pressure head folding process of last mold mechanism with press, by tapered punch hollow pipe is pushed and to make its plastic deformation form the taper hollow pipe.Therefore the taper hollow pipe that adopts cold stamping to make hollow pipe reach the necking down deformation technique and make has production efficiency height and advantage of low manufacturing cost.But the employing Sheet Metal Forming Technology can only be at the relatively thin hollow pipe of tube wall, but for the hollow pipe of heavy wall, as adopt the stamping die punching press to make the taper hollow pipe, then need bigger stamping press just can make the tube wall generation plastic deformation of hollow pipe and reach needed taper hollow pipe, but cold-stamped forming pressure too conference causes breaking of hollow pipe tube wall or surface wrinkling and scraps, the yield rate of product is descended significantly, and therefore, it is then not too suitable to adopt cold punching to make the taper hollow pipe.At present, also having is to adopt turning to process the taper hollow pipe, but this processing method needs the wall thickness of hollow pipe to reserve certain allowance, and not only amount of machining is very big, and also the stock utilization of Jiang Diing causes production cost high.
Summary of the invention
The purpose of this utility model provides a kind of reducing production costs, and improves the forging and molding device of the heavy wall taper hollow pipe of yield rate.
The utility model is that the technical scheme that achieves the above object is: a kind of forging and molding device of heavy wall taper hollow pipe, it is characterized in that: comprise upper bolster, die shoe and lead, the bottom of described upper bolster is provided with the last deep-slotted chip breaker of taper, top on the die shoe is provided with the arc lower groove identical with last deep-slotted chip breaker tapering, the groove depth H2 of the arc lower groove on the die shoe is 1.5～2 times of groove depth H1 of the last deep-slotted chip breaker of upper bolster, at least plural lead is fixed on the die shoe, and each pilot hole on the upper bolster is sleeved on each lead and can relatively moves.
The forging and molding device of the utility model heavy wall taper hollow pipe adopts on the upper bolster with deep-slotted chip breaker in the taper and has the die shoe of taper arc lower groove, therefore forge in the arc lower groove of heavy wall hollow pipe deep-slotted chip breaker and die shoe on upper bolster, last deep-slotted chip breaker by taper and arc lower groove push hollow pipe and make metal material generation plastic deformation make the taper hollow pipe, solved that heavy wall hollow pipe tube wall when cold stamping breaks or the phenomenon of surface wrinkling, because the wall thickness of hollow pipe is unrestricted, applicable to the making of the taper hollow pipe of different-thickness.It is 1.5～2 times of groove depth H1 of going up deep-slotted chip breaker that the utility model is designed to the groove depth H2 of arc lower groove, both made things convenient for hollow pipe had been placed in the arc lower groove, can prevent effectively that again hollow pipe from jumping out in the process of forging, can improve the security of operation in die shoe.Upper bolster of the present utility model is when knee-action, upper bolster is led by lead, therefore upper bolster can only move up and down, and can not be offset, can guarantee to make can not being out of shape of taper hollow pipe, the size and the form and position tolerance of the taper hollow pipe that is shaped satisfy designing requirement fully, can not only improve yield rate, and reduction manufactures cost.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model conical pipe forging and molding device.
Fig. 2 is the sectional structure chart of the A-A of Fig. 1.
Wherein: 1-upper bolster, the last dovetail of 11-, the last deep-slotted chip breaker of 12-, 2-lead, 3-die shoe, dovetail under the 31-, 32-arc lower groove, 4-hollow pipe, 5-clamp.
The specific embodiment
See shown in Fig. 1～2, the forging and molding device of heavy wall taper hollow pipe of the present utility model, comprise upper bolster 1, die shoe 3 and lead 2, the bottom of upper bolster 1 is provided with the last deep-slotted chip breaker 12 of taper, top on the die shoe 3 is provided with and the identical arc lower groove 32 of last deep-slotted chip breaker 12 taperings, see shown in Fig. 1～2, when upper bolster 1 fastens with die shoe 3, last deep-slotted chip breaker 12 and arc lower groove 32 constitute the taper hole of flat, and the groove depth H2 of the arc lower groove 32 on the die shoe 3 is 1.5～2 times of groove depth H1 of the last deep-slotted chip breaker 12 of upper bolster 1, at least plural lead 2 is fixed on the die shoe 3, can around die shoe 3, four leads 2 be set, each pilot hole of upper bolster 1 is sleeved on each lead 2 and can relatively moves, and by lead 2 upper bolster 1 can only be moved up and down, and can not be offset.See shown in Figure 1, the top of the utility model upper bolster 1 is provided with dovetail 11 or goes up dovetail groove, can be connected with dovetail groove or the dovetail on the forging hammer, conveniently upper bolster 1 is connected on the forging hammer, upper bolster 1 moves up and down with forging hammer and forges hollow pipe 4, and the bottom of die shoe 3 is provided with down dovetail 31 or following dovetail groove, can be connected with dovetail groove or the dovetail on the workbench, conveniently die shoe 3 is connected on the workbench.
See shown in Figure 2, during the utility model work, hollow pipe 4 one sides that will be heated to forging temperature by clamp 5 are clamped, arc lower groove 32 inner vortexs of hollow pipe 4 on die shoe 3 rotate continuously, forging hammer drives upper bolster 1 and pumps, make hollow pipe 4 distortion by last deep-slotted chip breaker 12 on the upper bolster 1 and the arc lower groove 32 on the die shoe 3, till hollow pipe 4 is deformed into required taper hollow pipe.
