Abstract
A device for adjusting a rotating drum of an inclined pipe-rolling machine relates to steel rolling machinery and resolves the problem that a feed-in angle of a roller in the prior art is inaccurate. An adjusting mechanism of the device for adjusting the rotating drum of the inclined pipe-rolling machine is formed by combining a lead screw lifting adjusting mechanism and a hydraulic cylinder locking mechanism. The lead screw lifting adjusting mechanism is composed of a lead screw lifting machine, a speed reducing motor, an encoder and a position controller. The speed reducing motor is directly connected with one end of an input shaft of the lead screw lifting machine, and the other end of the input shaft of the lead screw lifting machine is connected with the encoder. An output shaft of the lead screw lifting machine is a lead screw, the upper end of the lead screw is connected with the position controller, and the lower end of the lead screw is connected with the rotating drum in contacting mode. The hydraulic cylinder locking mechanism is a constant-speed oil cylinder, a cylinder body of the constant-speed oil cylinder is connected onto a machine frame, and a piston rod is connected with the rotating drum in contacting mode. The device for adjusting the rotating drum of the inclined pipe-rolling machine is used for adjusting the feed-in angle of the roller of the inclined pipe-rolling machine, can bear large rolling force and satisfies steel tube accuracy requirements of seamless steel tube production, and adjustment accuracy is accurate.
Description
Technical field
The utility model belongs to rolling machinery, specially refers to the diagonal rolling pipe mill in the seamless steel tube production.
Background technology
In seamless steel tube production, diagonal rolling pipe mill according to the specification of rolling pipe, needs to change the feed angle that is contained in roll in the rotary drum, to improve the quality of pipe when rolled steel tube.This adjustment rotary drum is called the rotary drum adjusting device to change the mechanism of roll feed angle.It needs accurately to adjust the feed angle of roll on the one hand, also enough stability must be arranged on the other hand, bears the rolling power of tumbling of rolled steel tube.
As shown in Figure 1, existing diagonal rolling pipe mill is adjusted rotary drum with the poke-rod type guiding mechanism.The rotary drum adjusting device comprises: rotary drum 1, guiding mechanism 2, frame 3, guiding mechanism 2 are contained on the frame 3, are contained in rotary drum 1 in the frame 3 in order to adjusting.Described guiding mechanism 2 is made up of driving lever 201, gyroaxis 202, screw-threaded shaft elevator 203, reducing motor 204, rotary drum locking cylinder 205 and semicircle slide plate 206.
The adjustment process of rotary drum adjusting device is: reducing motor 204 rotations, the leading screw that drives screw-threaded shaft elevator 203 is flexible, cause that driving lever 201 rotates around gyroaxis 202, stir rotary drum 1 around its angle of revolution, center α (roll feed angle), then, the plunger that is contained in two rotary drum locking cylinders 205 in the frame 3 stretches out, and forms with joint efforts with two semicircle slide plates 206 that are contained in the frame 3, with rotary drum 1 locking, the rolling power of tumbling of bearing rolled steel tube.
This existing rotary drum adjusting device when adjusting angle, must unclamp two rotary drum locking cylinders 205, and rotary drum 1 could rotate, and when driving lever 201 was stirred rotary drum 1, rotary drum 1 also can depart from the rotary drum center, adjusts the inaccurate of angle [alpha] and cause.In addition, the wearing and tearing of driving lever 201 and rotary drum groove 101, and being slidingly connected of driving lever 201 and rotary drum groove 101, the non-linear ratio of generation adjusts, and can make the distortion in readings of computer control reducing motor 204, causes and adjusts the inaccurate of angle [alpha].
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of diagonal rolling pipe mill rotary drum adjusting device is provided, and solves existing rotary drum adjusting device, adjusts the inaccurate problem of roll feed angle.
The utility model is achieved in that
A kind of diagonal rolling pipe mill rotary drum adjusting device, comprise: rotary drum, guiding mechanism, frame, described guiding mechanism is contained on the frame, is contained in rotary drum in the frame in order to adjusting, and it is characterized in that: described guiding mechanism is to be combined by leading screw lift adjustment mechanism and hydraulic locking cylinder mechanism; Described leading screw lift adjustment mechanism is made up of screw-threaded shaft elevator, reducing motor, encoder and positioner, described reducing motor directly is connected the end that screw-threaded shaft elevator is gone into axle, the other end that screw-threaded shaft elevator is gone into axle is connected with described encoder, the shaft of described screw-threaded shaft elevator is a leading screw, the upper end of described leading screw is connected with described positioner, and the lower end of described leading screw is connected with described rotary drum contact; Described hydraulic locking cylinder mechanism is a constant speed oil cylinder, and its cylinder body is connected on the frame, and piston rod is connected with the rotary drum contact.
The utility model because leading screw lift adjustment mechanism and hydraulic locking cylinder mechanism, is perpendicular to the frame slide plate and regulates drum rotating, thereby can not produce the gap compared with prior art, guaranteed that feed angle adjusts accurately; Because leading screw lift adjustment mechanism directly is connected on the rotary drum, the two does not have relative motion, so just can make the accuracy of reading of encoder, makes the control of operation computer accurately put in place yet, can satisfy the demand of seamless steel tube production steel pipe precision.Adjust precision accurately, can bear a kind of rotary drum adjusting device of the big rolling power of tumbling.
