Abstract
The utility model discloses a transmission shaft rapid roll changing gear used for a pipe welder, the transmission shaft rapid roll changing gear used for the pipe welder is arranged on a support of the pipe welder, the support is connected with a cardan shaft flange and a roller clutch flange through a square bearing, a transition shaft is arranged inside the square bearing, the rear end of the transmission shaft is closely connected with the cardan shaft flange, a sliding clutch flange capable of sliding backward and forward is arranged on the periphery of the front end of the transmission shaft, and the front end of the sliding clutch flange is closely connected with the roller clutch flange. According to the transmission shaft rapid roll changing gear used for the welded pipe unit, due to the fact that the transmission shaft and the clutch flanges are arranged in the middle of the transmission shaft rapid roll changing gear used for the welded pipe unit, the roller is separated from the cardan shaft through sliding, time for changing the roller is shortened, and the transmission shaft rapid roll changing gear used for the welded pipe unit is simple to operate and convenient to use.
Description
Technical field
The utility model relates to a kind of steel rolling servicing unit, particularly a kind of power transmission shaft fast roll changing device for the welded tube unit.
Background technology
Existing cold roll forming, the transmission device of welded tube unit production line, all directly link to each other with roll mandrel by universal drive shaft, the weak point of this structure is when the product of making different size need be changed roll, need be with the flange bolt between universal drive shaft and the roll mandrel separately, at first will use crane to hang universal drive shaft when separating connecting bolt, by two people's demounting bolts, have ten six roots of sensation rolls on each welded tube unit, the flange of every universal drive shaft and roll mandrel is connected with ten bolts, and remodel needs to start three cranes at every turn, six people's operations, just can finish dismounting about eight hours, the time of always remodeling needs nearly about 13 hours.When producing thick-walled pipe sometimes, because bolt strength causes the bolt deformed damaged inadequately, all to change some bolts when changing specification at every turn.Thereby, increase cost, reduce production efficiency.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of power transmission shaft fast roll changing device for the welded tube unit, is beneficial to shorten roll changing time, and is easy to operate.
To achieve these goals, the technical solution adopted in the utility model provides a kind of power transmission shaft fast roll changing device for the welded tube unit, this device is arranged on the support of welded tube mill, this support holds by square shaft and is connected with universal drive shaft flange and roll clutch flange, in holding, described square shaft is provided with transition axis, described transition axis rear end and described universal drive shaft flange are fastenedly connected, the front end periphery be provided with can before and after the slide engaging and disengaging flange that slides, described slide engaging and disengaging flange front end and described roll clutch flange are fastenedly connected.
The described slide engaging and disengaging flange of going up is connected with bottom roll clutch flange spline with topping roll clutch flange with lower slider clutch flange.
Effect of the present utility model is the power transmission shaft fast roll changing device for the welded tube unit, by a transition axis and clutch flange are set in the centre, by sliding, roll is separated in universal drive shaft, this fast roll changing device only needs one man operation can finish the dismounting of a power transmission shaft when changing specification.At first the bolt on the slip flange is unclamped, the slip flange is slided gets final product itself and power transmission shaft disengaging then, need not crane and cooperates.Only need two people, about about 1 hour time can finish the dismounting of ten six roots of sensation connecting axles when remodeling, about six hours of the whole time of remodeling can finish now at every turn.Shorten the used time of roll change greatly, enhanced productivity, reduced labour intensity, simple to operate, easy to use.
Description of drawings
Fig. 1 is the structural representation of the power transmission shaft fast roll changing device for the welded tube unit of the present utility model.
Among the figure: 1, support 2, cylinder 3, square shaft hold 4, transition axis
5, slide engaging and disengaging flange 6, roll clutch flange 7, universal drive shaft flange
The specific embodiment
Described in detail below in conjunction with the structure of accompanying drawing to the power transmission shaft fast roll changing device for the welded tube unit of the present utility model.
As shown in Figure 1, a kind of power transmission shaft fast roll changing device for the welded tube unit of the present utility model, this device is arranged on the support 1 of welded tube mill, this support 1 holds 3 by square shaft and is connected with universal drive shaft flange 7 and roll clutch flange 5, described square shaft holds and is provided with transition axis 4 in 3, described transition axis 4 rear ends and described universal drive shaft flange 7 are fastenedly connected, the front end periphery be provided with can before and after the slide engaging and disengaging flange 5 that slides, described slide engaging and disengaging flange 5 front ends are connected with described roll clutch flange 6 splines.
The operation principle of the power transmission shaft fast roll changing device for the welded tube unit of the present utility model is as follows:
When needs dismountings roll, unclamp for the bolt of clutch flange 5 on transition axis 4, and slide engaging and disengaging flange 5 is sliding backward, up to separating with roll mandrel clutch flange 6, carry out roll change work.When having changed roll, when assembling, slide engaging and disengaging flange 5 to front slide, and is connected by spline at precalculated position and clutch flange 6 on transition axis 4, after with slide engaging and disengaging flange 5 by bolting to transition axis 4, finish the transmission of power.
Each support is provided with two groups of rolls, can operate simultaneously.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.
