Description

Inside and outside shaping swager
Technical field
The utility model relates to the inside and outside shaping swager of a kind of bar, belongs to the material processing machine field.Forging of its adaptation solid or hollow bar that diameter is bigger, cross sectional shape is more complicated.
Background technology
Chinese patent ZL200620078595.3 is the minor diameter solid bar reducing swager that my company designs, makes voluntarily in 2005 annual proper motions.The primary structure of this swager is the disk that has three road chutes that is connected of the axle end in rotation, embeds forging die, wedge, slide block, roller in the chute successively, and the roller outside is a drum; Wedge one end connects main shaft, and this axle is driven by servomotor by a paranema thick stick nut and moves axially (producing the reducing effect); By synchronous belt drive, the recoil strength that produces of the rotating band movable slider bump roller by axle forges axle simultaneously by motor; Though this technology has solved the reducing problem that forges, because drum is the fixed structure formula, so be that the processing that forges of outer polygon and major diameter, hollow bar then seems powerless for cross sectional shape.Therefore, the range of application of this swager product processed is subjected to greatly limiting.
Summary of the invention
The purpose of this utility model is in order to remedy the deficiency in the above-mentioned patented technology, fixed structure formula drum to be designed to turnably; In addition, also dispose core for forging die.Thereby can forge out more complicated parts of cross sectional shape, greatly expand the range of application of part.
The utility model is realized by following technical scheme: described inside and outside shaping swager, it is mainly forged mechanism and is forged diameter of part size adjustment mechanism and formed by the axle of the rotation disc type that is connected.Wherein disc type forges mechanism and evenly be provided with chute on disc, forging die, swash plate, slide block from inside to outside are housed in the chute successively, be equipped with on annular retainer, the retainer at the peripheral equipment of disc and be evenly distributed with roller, the peripheral equipment of retainer is equipped with drum; Being forged diameter of part size adjustment mechanism is main shaft by side-to-side movement, and the one end connects swash plate, and the other end connects the hydraulic pressure rocker arm body and constitutes, and wherein the hydraulic pressure rocker arm body is to connect rocking arm by the oil cylinder connecting rod by articulated elements, is provided with the rotation sliding sleeve in the rocking arm and constitutes.Described drum connects driving by motor by trapezoidal synchronous band and can rotate separately; Axle connects driving by motor by triangular driving band; Beyond forging die, can be provided with and be used the core of processing hollow parts with forging die.
The utility model is for prior art: owing to changed the fixed structure formula of former drum is the turntable formula; In addition, also dispose corresponding core for forging die.Make the equipment of original cylindrical component that only can the processing reducing after improving, can forge out more complicated parts of cross sectional shape, greatly expanded the range of application of part.

The specific embodiment
Above-mentioned accompanying drawing has provided embodiment of the present utility model.Below in conjunction with accompanying drawing overall structure of the present utility model and operation principle thereof are described in detail:
As shown in Figure 1, 2, this inside and outside shaping swager is mainly forged mechanism and is forged diameter of part size adjustment mechanism by the fixedly connected disc type of axle of rotating and forms.Wherein disc type forges mechanism four road radial grooves (also can be two, three, six roads) evenly is set on disc 1, from inside to outside embed successively in the per pass chute forging die 3, swash plate 4, slide block 6 are arranged, be equipped with evenly to distribute on annular retainer 5, the retainer at the peripheral equipment of disc 1 roller 7 is housed, roller is an even number, and the drum 8 that can rotate separately that is peripherally equipped with of retainer constitutes; Being forged diameter of part size adjustment mechanism is main shaft 10 by side-to-side movement, and the one end connects swash plate, and the other end connects the hydraulic pressure rocker arm body and constitutes; Wherein the hydraulic pressure rocker arm body connects rocking arm 12 by oil cylinder connecting rod 15 by articulated elements 16, and device rotation sliding sleeve 11 constitutes in the rocking arm.Shown in Figure 3, described rotation sliding sleeve 11 is that the end at main shaft 10 is provided with bearing 17, and bearing outer ring is slide block 21 fixedly, and the slide block both sides are provided with end cap 18, between slide block and both sides end cap, embed the needle roller 19 that has retainer 20, and the both sides end cap is made of cover for seat 22 connection institutes; Its middle (center) bearing 17 1 ends lean against on the shaft shoulder of main shaft 10, and its other end is fixed on the main shaft 10 by round nut 25 by top cover 24; The other end of main shaft 10 and swash plate 4 join and drive swash plate and do side-to-side movement.Described drum connects driving by motor by trapezoidal synchronous band; Axle connects driving by motor by triangular driving band; Can also be provided with in addition with forging die at forging die and to be used the core 13 that needs when processing hollow parts, this core send core mechanism to finish by special.
The operation principle of inside and outside shaping swager: referring to Fig. 1,2, the part blank 14 that will process is earlier sent in the forging die 3 of swager by feed mechanism, when axle was rotated by the triangular driving band driving by motor, joining with it disc 1 rotated thereupon; Hydraulic pressure rocker arm body work simultaneously, its principle are that oil cylinder promotes connecting rod 15 and by articulated elements 16 rocking arm 12 swung, and with the hinged rotation sliding sleeve 11 of rocking arm 12 main shaft are produced and move axially.See Fig. 3, the course of work of rotation sliding sleeve is like this: when main shaft 10 rotated, the inner ring of bearing 17, top cover 24 and round nut 25 were followed together and are rotated.Because the swing of rocking arm makes cover for seat 22 fluctuate,, so just relative slip and problem have in relative rotation been solved because the effect of prepositioned retainer 20 and needle roller 19 in fluted makes the relative slip of end cap 18 and slide block 21 be achieved; Main shaft 10 orders about swash plate 4 and realizes the reducing effect with respect to forging die 3 do axially-movable.Because action of centrifugal force, slide block 6 and forging die 3 outwards move and are in open configuration along chute; This moment, drum 8 drove turn clockwise (also can be rotated counterclockwise in case of necessity) by motor by trapezoidal synchronous band; When the axle band slide block 6 and is rotated counterclockwise with roller 7 contacted positions, roller and drum forced the slide block band forging die to central motion, made it to produce to axially and the compression of heart portion to hit blank 14.When forging hollow bar, the endoporus of blank 14 is shaped and is finished by core 13, and core is by the special mold mechanism that send core to be inserted, and this moment, processed part was the servo-actuated rotation, and so just can be shaped has the polygonal part of accurate dimension.When being shaped according to not coexisting of blank material needs fast, at a slow speed, the forging of middling speed: when needs forged fast, drum 8 was done the reverse rotation campaign with axle 9; When needs forged at a slow speed, drum and axle rotatablely moved in the same way; When the needs middling speed forges, be achieved by lock barrel.Difference according to the part section shape that will be shaped: carry out forging of outer polygonal part by locking spindle and allotment forging die; Carry out forging of inner polygon part by the allotment core.
