Description

Work roll positioning device

technical field

The invention relates to the technical field of rolling mills, in particular to a work roll positioning device.

Background technique

The cold-strip rolling mill has load-bearing rolls and work rolls arranged above the load-bearing rolls. When rolling, the steel bar is dragged by the motor, and the load-bearing rolls and work rolls jointly apply force to the two surfaces of the steel bar, and by changing the two The size of the gap between the rolls enables the rolling of cold-rolled ribbed steel bars of different diameters, the load-bearing rolls produce ribs on the lower surface of the steel bars, and the work rolls produce ribs on the upper surface of the steel bars. When adjusting the gap between the two rolls, the adjustment is realized by moving the work rolls. The work roll is installed on the work roll positioning device, which is beneficial to the positioning, position adjustment and replacement of the work roll. The existing work roll positioning device includes a sliding seat and a supporting arm fixed on one side of the sliding seat. The working roll is lifted by the supporting arm, and the lifting and sliding of the sliding seat drives the supporting arm to lift and slide integrally, thereby adjusting the position height of the working roll. However, the support arm cannot buffer the load-bearing impulse when it carries the work rolls. Because the work rolls are heavy, when the work rolls are installed on the support arm, the support arm is greatly impacted by the load and is easily damaged.

Please refer to FIG. 1 again, the elastic reset mechanism 40 includes a spring pin 41 , a hinge shaft 42 , a spring 43 and a spring locking pad 44 . A collar 411 is formed at one end of the spring pin 41 . During installation, one end of the spring pin 41 extends into the assembly groove 13 through the perforation 114 on the hinged wall 111, and the spring 43 is sleeved on a section where the spring pin 41 penetrates into the assembly groove 13, and through the spring locking pad 44 The locking maintaining spring 43 is against the hinged wall 111 ; one end of the spring pin 41 with the collar 411 is accommodated in the notch 14 of the adjusting seat 10 .

Please refer to Fig. 8 and Fig. 9, when assembling the work roll positioning device, assemble the sliding seat 20 and the adjusting seat 10, the clamping groove 231 of the sliding seat 20 clamps the clamping body 113 of the adjusting seat 10, and the two sides of the clamping groove 231 The third hinge hole 212 on the side wall is aligned with the ring sleeve 411 at the end of the spring pin 41, and the hinge shaft 42 passes through the third hinge hole 212 and the ring sleeve 411, so that the spring pin 41 and the slide seat 20 are hinged, that is, the The upper end of one side of the sliding seat 20 is hinged to the upper end of the hinged side 11 . The second hinge hole 211 on the both sides of the clamping groove 231 is aligned with the first hinge hole 151 of the hinge section 15, and a hinge nail 50 is provided to pass through the second hinge hole 211 and the first hinge hole 151, so that the slide seat The lower end of one side of 20 is hinged with the lower end of hinged side 11 . After installation, there is a certain gap between the end surface of the hinge section 15 and the bottom surface of the clamping groove 231 to provide a space for the adjustment seat 10 to swing relative to the sliding seat 20 around the hinge nail 50 .

Install the bracket arm 30 to the fixed side 12 of the adjustment seat 10, the slot 311 of the bracket arm 30 cooperates with the protrusion 122 of the fixed wall 12, and provides a pin (not shown) to pass through the second pin hole 312 and the protrusion The first pin hole 123 on the 122 is matched to fix the support arm 30 to the adjustment base 10 .

When the work roll positioning device is carrying the work roll, the shaft head of the work roll is pressed against the lift groove 321 of the lift end 32 of the support arm 30, and pressed against the two roller bearings 33. When pressed, due to the work The weight of the roll is heavy, and under the impact of bearing pressure, the support arm 30 will swing downward with the adjustment seat 10 relative to the slide seat 20 around the hinge nail 50 to a certain extent to provide a buffer for the pressure of the work roll. When swinging downwards, the lower end of the hinged side 11 of the adjustment seat 10 swings around the hinge nail 50. One end of the pin 41 is affixed to the sliding seat 20 through the hinge shaft 42. In this way, the adjusting seat 10 will further compress the spring 43, and the elastic force of the spring 43 will further increase, and the spring 43 provides the force to return the adjusting seat 10 to the original position relative to the sliding seat 20. force. After the work roll is installed in the lifting groove 321 of the support arm 30 and stabilized, the spring 43 presses against the hinged side 11 of the adjustment seat 10 and gradually stretches to the original stretching degree, so that the adjustment seat 10 rotates around the hinge nail 50 relative to the sliding seat 20 Swing up a certain swing and return to the original position. When the work roll needs to adjust the position and height, the driving end of the driving device pushes the sliding seat 20 to rise or fall, thereby driving the adjustment seat 10 to move together with the supporting arm 30 to achieve height adjustment. And when the sliding seat 20 is raised or lowered, the roller 24 is arranged at the bottom of the body 21 to cooperate with the guide rail to slide, so as to guide the sliding seat 20 to go up and down.

To sum up, the working roll positioning device of the present invention hinges the supporting arm on one side of the adjusting seat, and the other side of the adjusting seat is fixedly connected to the sliding seat. When the supporting arm carries the working rolls, the supporting arm can have a certain swing relative to the adjusting seat. Width, forming a certain buffer displacement, which can help protect the support arm and is not easy to be damaged. And by setting the roller bearing for lifting at the lifting end of the supporting arm, the working rolls lifted will not contact and rub against the supporting arm, thus protecting the supporting arm. In addition, the replacement of the support arm is facilitated by detachably connecting the support arm to the adjustment seat.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process conversion made by using the content of the description of the present invention, or directly or indirectly used in other related technical fields, shall be The same reasoning is included in the patent protection scope of the present invention.
