Fig. 2 is a left view of the present utility model;
Fig. 3 is a vertical view of the present utility model;
Fig. 4 is the structural representation of cylinder of the present utility model or fluid pressure drive device.
The specific embodiment
As shown in Figure 1, be provided with axle 2 in the centre position of frame 1, working face 3 is exposed on axle 2 tops, connects center die 4 thereon, is provided with gear 5 in the lower end of axle 2, is connected with reductor, motor 6.Described reductor, motor 6 rotate, and drive center die 4 by axle 2 and rotate.
Shown in Fig. 2,4, working face 3 is a rectangle, and difference vertical fixing support 7a, 7b are connected with lowering or hoisting gear 8 respectively on support 7a, 7b on the center of two long limit A, B, described lowering or hoisting gear 8 can constitute by connecting rotating disk 29 on the screw rod 28, also can be made by cylinder or oil cylinder 30.On described lowering or hoisting gear 8, be provided with guide rail 9,, just on screw rod 28, connect guide rail 9, if cylinder or oil cylinder 30 just connect guide rail 9 on its piston 31 if elevating mechanism is to connect rotating disk 29 on the screw rod 28 to constitute.Below guide rail 9, connect pinch roller 10 then.The a pair of device at this place is a Working piece positioning device 15, its role is to: Working piece positioning device is the center with center die 4, is distributed in its both sides, regulates by the height of 8 pairs of workpiece anchor points of lowering or hoisting gear, to guarantee accurate positioning.
As shown in Figure 3, originally also can be to Working piece positioning device 15 location with the fine location of workpiece with this, but for location better, at the corresponding a pair of identical Working piece positioning device 16 that also is provided with of the termination diagonal positions of working face 3 liang long limit A, B.Described Working piece positioning device is fixed on the working face 3 by support 13 by front and back drive unit 12, and the end connection guide rail 14 at front and back drive unit 12 connects locating wheel 11 and constitutes on the guide rail 14.Can be identical in this front and back drive unit 12 and lowering or hoisting gear 8 structures, be not repeated at this.The effect of this Working piece positioning device 16 is: this Working piece positioning device 16 is to give the workpiece location from the position, front and back, and concrete distance can be regulated by front and back drive unit 12, and is flexible.To the workpiece location, one positions from the front and back distance, has guaranteed the accuracy of workpiece location from the height for 15, one of this Working piece positioning device 16 and above-mentioned Working piece positioning devices.
Center on working face C limit, both two jiaos the diagonal positions limit that is provided with Working piece positioning device 16 was provided with pressue device 17.The support 18 of described pressue device 17 is vertically connected on the center of working face C, drive unit 19 before and after the frame bottom direction parallel with working face is connected with, and the structure of this front and back drive unit 19 is identical with above-mentioned front and back drive unit 12, this not tired stating; Be the 0-180 degree on the top of support 18 and be provided with pressue device 17.Described pressue device 17 is by being connected with guide rail 21 on the lowering or hoisting gear 20, guide rail 21 belows connect stamper support 22, and pressing mold 23 is connected on the stamper support 22 by axle 24.This apparatus features is: pressue device 17 can be adjusted distance by front and back drive unit 19 front and back, also can adjust distance up and down by elevating mechanism 20, like this, make pressue device no matter be under what specification at workpiece to be processed, all can on the die face of center die 4, find the optimum pressurized point, thereby make this machinery not only can produce the workpiece of different size, and can guarantee that the moulding of each workpiece is smooth, size is accurate.
As shown in Figure 3, during work, the part inwall of workpiece blank is attached on the center die 4, is located with front and back position from height respectively by Working piece positioning device 15 and 16, regulates pressue device 17 then, allows pressing mold 23 be in the optimum pressurized point; Open motor 6 then and drive center die 4 rotations, drive workpiece by center die 4 and rotate, reach the spinning purpose by axle 2.In this process, in order to reduce the frictional force that center die 4 drives workpiece, become each fixing pair of brackets 25 of diagonal positions at the D of working face face, fixed axis 26 between support, cover cylinder 27 on the axle 26.Cylinder 27 had both played supporting workpiece, rolled when operation again, reduced the frictional force of center die 4.
