Description
Technical field
The present invention relates to the using method of a kind of make-up machine and this make-up machine, specifically a kind of conical pipe forming machine and using method thereof that cooperates broaching machine to draw conical pipe.
Background technology
Everybody conical pipe of knowing generally is to adopt rolling method to make now.To be placed on as the iron charge of substrate on the workbench, utilize the large-tonnage hydraulic press rolling, need a plurality of staff to rotate iron charge with hydraulic press, it is cylindric to cause it to be rolled into, this preparation method wastes time and energy, inefficiency, and the conical pipe surface flatness of roll forming is poor, equipment funds have high input, and floor space is big.Because conical pipe is generally longer, do taperedly can guarantee its stability, but up to now, the precedent of also utilizing the principle that draws to make the reducing conical pipe.
Summary of the invention
The present invention be directed to deficiency of the prior art, one provides a kind of principle of utilizing drawing, cooperates broaching machine to make the conical pipe forming machine of reducing conical pipe, and two provide the using method of this conical pipe forming machine.
Realize the foregoing invention purpose by the following technical solutions: a kind of conical pipe forming machine, comprise casing, be evenly distributed on the worm screw on the casing circumference, idle wheel with the engagement of worm screw end gear, the reducing wheel seat is equipped with in described casing inside, be hinged with diameter-changing wheel with connector in the reducing wheel seat, described diameter-changing wheel one end is meshed with worm screw.
The using method of this conical pipe forming machine, it is operated according to following steps:
A, this conical pipe forming machine is fixed on the workbench, an idle wheel on its circumference is connected transmission with variable speed electric motors, particularly;
B, an end of the substrate of making conical pipe twisted on the cylinder iron core and fixing, the circle diameter of this iron core equates with the center-hole diameter of the A of diameter-changing wheel point formation;
C, iron core is passed the centre bore of casing, fixedly connected with the broaching machine of make-up machine back;
D, connection power supply are adjusted the speed that draws in of broaching machine and the rotating speed of idle wheel according to the conical pipe actual size;
E, in the process that broaching machine draws in substrate, diameter-changing wheel also rotates under the gearing of idle wheel and worm screw, forwards the B point to by the A point, with its diameter variation, substrate is drawn into conical pipe.
Compared with prior art, the present invention utilizes the principle of drawing to make the conical pipe of reducing first, and equipment cost is low, the production efficiency height, and the yield rate height, good product quality, the surface flatness height alleviates workman's manual labor.

Reducing wheel seat 1 among the figure, worm screw 2, diameter-changing wheel 3, casing 4, rotating shaft 5, idle wheel 6.
The specific embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Referring to accompanying drawing 1-5, in the present embodiment, lamp stand with the taper reducing is an example, eight reducing wheel seats 1 are installed in the casing 4 of this conical pipe forming machine to be formed, all be hinged with a diameter-changing wheel 3 in each reducing wheel seat 1 with rotating shaft 5, and an end of each diameter-changing wheel 3 all with worm screw 2 engaged transmission, worm screw 2 all is contained on the circumference of casing 4, gear all is equipped with in the end of worm screw 2, and this gear all with idle wheel 6 engaged transmission.Angle between per two reducing wheel seats 1 is 90 degree.The other end of eight diameter-changing wheels 3 is circular-arc, and the assembling back constitutes round center hole.Diameter-changing wheel 3 is made up of two parts of one, and the one side is the cam of reducing, and opposite side is isometrical gear, and the side of the cam of reducing is an arc groove.
The using method of this conical pipe forming machine, it is operated according to following steps:
A, this conical pipe forming machine is fixed on the workbench, an idle wheel 6 on its circumference is connected transmission with variable speed electric motors, particularly;
B, an end of the substrate iron charge of making lamp stand twisted on the cylinder iron core and its welding is fixing the equal diameters of the A centre bore that point constitutes of the circle diameter of this iron core and eight diameter-changing wheels 3;
C, iron core is passed the centre bore of casing 4, and fix with the broaching machine of make-up machine back;
D, connection power supply are adjusted the speed that draws in of broaching machine and the rotating speed of idle wheel 6 according to the actual size of lamp stand;
E, in the process that broaching machine draws in iron charge, diameter-changing wheel 3 also rotates under the gearing of idle wheel 6 and worm screw 2, is promptly forwarded in the process that B orders with its diameter variation by the A point, the lamp stand that draws moulding is taper, and the round center hole of A point formation does not change.
Based on centre bore, the thread rotary orientation of two worm screws 2 on same diameter is opposite.Generally speaking, the circle diameter that the A point constitutes on the diameter-changing wheel 3 is 70mm, and the circle diameter that the B point constitutes is 180-220mm, long and short variation according to lamp stand, adjust the fast, slow of idle wheel 6 rotating speeds, like this, the lamp stand that draws moulding is small end 70mm, holds the taper of 180-220mm greatly.
In practical operation,, also diameter-changing wheel 3 can be made into various ways such as four, six according to the requirement of machining accuracy.
