Specific embodiment
As shown in Figure 1, this New Tungsten disclosed in the present embodiment and tungsten alloy bar rounding apparatus, including fixed station 1, disk
Mold 2, operation handle 3, curved round force-applying piece 4.
The shape that can be seen that the present embodiment fixed station 1 with reference to Fig. 1, Fig. 2 is rectangle.The rectangle of 30~50mm can be used
Heat-resisting steel sheet and plate makes.The sidewall bottom of Disc mould 2 is machined with the circumferential groove in its end portion 21 that cross-sectional shape is rectangle.In fixed station 1
Upper thread mill drilling processes corresponding countersunk screw holes on Disc mould 2.Disc mould 2 is anchored on fixed station by sunk screw 5
1 upper surface, the circumferential groove in its end portion 21 on Disc mould 2 are located at the upside of fixed station 1.
The operation handle 3 of the present embodiment is made of heat-resisting round steel.With reference to Fig. 1 to Fig. 4 as can be seen that operation handle 3
One end bends 90 degree, and bending segment interference is connected with bearing 6.The center position of Disc mould 2 has the circular hole through its thickness,
The aperture of circular hole is more than the outer diameter of bearing 6.Operation handle 3 is connected to bearing 6 and circular hole clearance fit on Disc mould 2, is grasped
The shaft for making handle 3 is parallel with fixed station 1.The shaft interlude of operation handle 3 is thread segment, and curved round force-applying piece 4 is connected to spiral shell
In line section.
As shown in figure 3, curved round force-applying piece 4 includes nut 41 and limit base, limit base includes /V cylinder 42 and vertically connects
The connecting cylinder 43 being connected on the upside of it, the upper end of connecting cylinder 43 are connected with the side wall of nut 41.Nut 41 is connected to manipulator
On the shaft interlude of handle 3, the bottom surface of /V cylinder 42 is located at the upper surface of fixed station 1, the inside of /V cylinder and circle to be curved
The outer wall of rod piece is tangent.
The curved round force-applying piece of the present embodiment is made of heat-resisting tungsten alloy.
After fixed station, Disc mould and the operation handle of the present apparatus and curved round force-applying piece assemble, according to circular Curve to be curved
Diameter adjust the position of curved round force-applying piece in operation handle.Disc mould sidewall bottom will be rapidly inserted into after workpiece heat
In circumferential groove in its end portion, quick rotation operation handle, the curved round force-applying piece in operation handle makes the curved circle of rod piece with the rotation of operation handle.
Due to operation when rod piece accurate positioning it is quick, so rod piece it is curved circle processing time it is short, avoid the prior art appearance because
Black brittleness influences the defects of performance after being molded, and lumber recovery is high.
