Description

The reducing swager

Technical field

The utility model belongs to the material processing machine technical field, exactly is a kind of bar processing swager that can reducing.

Background technology

Existing bar processing swager, its operation principle is to rotate to hit by each parts in the rotating band motivation head of transmission main shaft to be clipped in the bar of doing axially-movable in the mould, reach the purpose of dwindling diameter of rod, that is to say the bar of the certain-length fixed diameter of when bar continuous motion vertically, can swaging out.Because the structural design of existing swager is limit, the mould radial motion position of swaging of swager is constant, it can't be swaged by reducing, so the diameter of rod of swaging out is fixed, and the tapering of can not swaging, the rotary body or the barred body of body complexity such as curve is arranged.

Summary of the invention

The purpose of this utility model is in order to overcome defective of the prior art, but a kind of reducing swager is provided, this swager bar of fixed diameter of can not only swaging out, and the tapering of swaging out, the rotary body of curve is arranged.

This purpose realizes with following technical proposal: this reducing swager, it mainly is made up of head and transmission mechanism, wherein head comprise existing floral disc, be evenly equipped with above the floral disc in three grooves, each groove therefrom mind-set outward successively device have outside mould, slide block, little ball, the floral disc side have that side has big ball, big ball to place on the retainer outside retainer, the little ball, side has the big steel ring of raceway outside retainer and big ball; Transmission mechanism comprises the existing running part that constitutes drive that head rotates and the transmission main shaft that is connected thereof that makes, and wherein the other end of transmission main shaft connects floral disc.Its special feature is that a side of the close mould of described slide block is the inclined-plane, is provided with wedge between slide block and mould, and the inclined-plane of wedge and slide block inclined-plane match, and end device is on small footprint under the wedge; On the small footprint of wedge, be connected with another running part that makes wedge do side-to-side movement, this running part is by nut seat, connect core bar at the one end, the other end connects the pinion mate of leading screw, leading screw other end connection travelling gear and travelling gear, and the pinion mate axle is provided with belt pulley and forms.

The utility model compared with prior art has the following advantages: this swager has been done improvement on the structure of its head, but make in the prior art mould of can not reducing swaging change the mould that reducing is swaged into, its transmission mechanism can be implemented in the surface of the different-diameter of swaging out in the same metal bar under the control of department's clothes motor is handled; Also can be implemented in the surface of the fixed diameter of swaging out in the same metal bar, that is to say its can not only swage out bar of fixed diameter, the tapering of also swaging out, the rotary body of curve be arranged.So can satisfy the different requirements in the industry fast, efficiently.This swager also improves the mechanical and physical performance of material simultaneously in the processing time material saving of swaging.

Fig. 1 is an internal structure schematic diagram of the present utility model.

Fig. 2 is that the utility model A-A is to cutaway view.

The specific embodiment

Below in conjunction with Figure of description unitary construction of the present utility model and operation principle thereof are done concrete detailed explanation.

As shown in Figure 1, 2, described reducing swager mainly is made up of head and transmission mechanism.Wherein head is by circular floral disc 1, be evenly distributed with three grooves above the (see figure 2) floral disc, in each groove therefrom mind-set outward successively device mould 2 is arranged, (referring to Fig. 1) makes the wedge 11 of side-to-side movement, slide block 3, slide block one side is the inclined-plane, inclined-plane on it and the wedge coincide, wherein the wedge lower end is passed floral disc and is placed on the small footprint 12, in the slide block outside little ball 4 is arranged, 12 big balls 5 are equipped with in the outside of little ball, one retainer 6 is arranged in the outside of floral disc, big ball places on the retainer 6 and can rotate flexibly, side is a big steel ring 7 of making raceway outside retainer and big ball, and above-mentioned each parts are made of handpiece case 8 packing institutes.Transmission mechanism is made up of two parts, a part is the transmission that head is rotated, it mainly is made of motor-driven drive 9 connection transmission main shafts 10, and wherein the other end of transmission main shaft connects floral disc 1, and drive rotates head by driven by motor; Another part is to make wedge 11 do the transmission of side-to-side movement, it is by nut seat 14, right-hand member at nut seat connects a core bar 13, left end connects a leading screw 15, the leading screw other end connects travelling gear 16, one pinion 17 and travelling gear engagement are arranged, belt pulley 18 is housed on pinion shaft, and belt pulley is made of department's clothes driven by motor.Described transmission main shaft 10 is a hollow shaft, and core bar 13 passes and joins with the small footprint 12 of wedge from hollow.Belt pulley 18 is by department's clothes driven by motor and be subjected to computer control to make wedge do side-to-side movement.

The operation principle of reducing swager: see Fig. 2, when main shaft 10 rotations, joining with it floral disc 1 rotates thereupon, three little ball 4 continuously and smoothlies collide the big ball 5 in the bump outside, because continuously uniform impact force of big or small ball and action of centrifugal force, it is radially reciprocating in the groove of floral disc to make slide block 3 drive moulds 2, because 12 big balls 5 on the retainer are even distributions, so three moulds 2 are to be synchronized with the movement, the bar in the middle of the mould 2 of so just can swaging continuously.

See Fig. 1, because the wedge 11 between mould 2 and the slide block 3 is just changeing counter-rotating by belt pulley, gear train by department's clothes motor, under the control of driving-chains such as feed screw nut group and core bar 13 in move left and right, control the radial distance of the working face of mould 2 by the relative motion on wedge and slide block inclined-plane, so just can reach the purpose of controlling the excellent diameter of swaging by the motion of computer control department clothes motor to pivot.In rotary swaging process, metal bar in the middle of the mould also is to obey motor by the department of itself to pass through its driving-chains such as feed screw nut and be correlated with to clamp its side-to-side movement of mechanism controls, computer reaches die-face in radially motion according to certain rules according to the characteristics of motion of its programme-control department clothes motor, metal bar is motion vertically, the continuous operation metal bar of cylinder, circular cone and complex-curved rotary body of can swaging out so according to certain rules also.
