Abstract
The invention relates to a sizing mill capable of adjusting a roll gap manually. The sizing mill is characterized in that three roller components are arranged on a sliding block in a rotational mode respectively; the sliding block can slide along the radial direction of a hole pattern and is provided with an inclined plane; three wedge blocks are arranged in a machine frame body in a movable mode respectively; and an inclined plane of each wedge block is in contact fit with the inclined plane of the sliding block. The sizing mill is simple and compact in structure; and the three roller components are respectively arranged on the sliding block which moves synchronously to adjust the roll gap quickly, so that the roll gap is adjusted conveniently and quickly, the maintenance workload of a production line is reduced, the maintenance period of the production line is shortened, waste is reduced, the maintenance cost is reduced, and the production efficiency and the quality of seamless steel tubes are improved.
Description
Technical field
The present invention relates to a kind of seamless steel pipe production, especially relate to a kind of sizing mill that can manually adjust roll gap.
Background technology
At present, on seamless steel tube production chain, sizing mill used generally includes three roll parts, the adjustment of the roll gap between its three rolls normally relies on the adjustment spacer thickness that three axles are fastened to adjust, and just in assembling process, the mode with pad is adjusted, sizing mill manufacturer gives after seamless steel tubing mill, can not adjust online.In the process of rolled steel tube, due to discontinuity or other reason make three rolls between gap (roll gap) change, thereby the quality of influence of rolled seamless steel pipe.Current common way is that three rolls of sizing mill are processed, the aperture that adds macroporous type, the sizing mill that the used for sizing mill of production line front portion is new substitutes, and the sizing mill after processing is moved backward, and be arranged on the last sizing mill of production line, just loses efficacy superseded, make like this maintenance workload of production line large, maintenance period is long, wastes very greatly, and maintenance cost is high, and waste time and energy, production efficiency is low.
Summary of the invention
The applicant is for above-mentioned problem, be studied improvement, a kind of sizing mill that can manually adjust roll gap is provided, simple and compact for structure, roll gap easy to adjust quick, reduce the maintenance workload of production line, the maintenance period that shortens production line, cuts the waste, and reduces maintenance cost, enhance productivity, improve seamless steel pipe quality.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of sizing mill that can manually adjust roll gap, comprise Rack Body, three roll parts are arranged in described Rack Body, the axis of three roll parts forms equilateral triangle, the roll of three roll parts forms the pass of rolled steel tube, three described roll parts are rotatably arranged on slide block respectively, described slide block is slidably mounted in described Rack Body, described slide block can radially sliding along described pass, described slide block is provided with inclined-plane, three voussoirs are movably arranged in described Rack Body, and described in each, the inclined-plane of voussoir contacts cooperation with the inclined-plane of described slide block respectively; One side of support body is provided with inner cap and enclosing cover, and ring gear is rotatably arranged between the inner cap and enclosing cover of Rack Body one side, and described ring gear is coaxial with described pass; Three swivel nuts described voussoir that is threaded respectively, described swivel nut is cup-shaped, the flange of described swivel nut is spacing in described Rack Body, drive rod is sleeved in described swivel nut, swivel nut described in described drive rod spline joint, drive rod described in pinion spline joint, described pinion and the engagement of described ring gear, spring supports and is contained between the bottom surface of described swivel nut and the boss of described drive rod.
Further:

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 2, the present invention includes Rack Body 1, Rack Body 1 is cylindrical, three roll parts 2 are arranged in Rack Body 1, the axis of three roll parts 2 forms equilateral triangle, the roll 201 of three roll parts 2 forms the pass 3 of rolled steel tube, three roll parts 2 are rotatably arranged on slide block 4 by bearing respectively, slide block 4 is slidably mounted in Rack Body 1, slide block 4 can, along the radially sliding of pass 3, in the present embodiment, be provided with the guide rail 5 radially arranging along pass 3 in Rack Body 1, slide block 4 slides along guide rail 5, guarantees the accuracy that slide block 4 slides.Slide block 4 is provided with inclined-plane, and three voussoirs 6 are movably arranged in Rack Body 1, and the inclined-plane of each voussoir 6 coordinates with the inclined-plane contact of corresponding slide block 4.One side of Rack Body 1 is provided with inner cap 101 and enclosing cover 102, ring gear 7 is rotatably arranged between the inner cap 101 and enclosing cover 102 of Rack Body 1 one sides, ring gear 7 is coaxial with pass 3, three swivel nuts 8 voussoir 6 that is threaded respectively, rotary threaded sleeve 8 can make voussoir 6 move back and forth up and down (as Fig. 2), swivel nut 8 is cup-shaped, and the flange 801 of swivel nut 8 is spacing by inner cap 101, and swivel nut 8 only can rotate and can not do axially-movable.Three drive rods 9 are sleeved in swivel nut 8, drive rod 9 connects swivel nut 8(as Fig. 3 by spline 902), pinion 10 connects drive rod 9 by spline 902, pinion 10 and ring gear 7 engagements, spring 11 supports and is contained between the bottom surface of swivel nut 8 and the boss of drive rod 9, rotate any drive rod 9 and can drive pinion 10 to rotate, and drive other two pinions 10 synchronously to rotate by ring gear 7, thereby band movable snail sleeve 8 synchronously rotates.The outer end of drive rod 9 is provided with square toes 901, conveniently utilizes tool operation drive rod 9.
When adjusting the roll gap of roll 201 of three roll parts 2, with spanner, rotate any in three drive rods 9, drive rod 9 band movable snail sleeves 8 and pinion 10 rotate, by swivel nut 8, drive voussoir 6 to move, effect driving slide block 4 by voussoir 6 by inclined-plane moves radially, thereby drives the roll 201 of roll parts 2 to move radially; Due to three pinions 10 and ring gear 7 engagements, by a pinion 10, drive ring gear 7 to rotate, ring gear 7 drives two other pinion 10 synchronously to rotate, thereby make two other swivel nut 8 drive voussoir 6 and slide block 4 synchronizing movings, thereby drive the roll 201 of three roll parts 2 synchronously to move radially, thereby reach the object of the roll gap of the roll 201 of adjusting three roll parts 2, make the arc surface of the roll 201 of three roll parts 2 form Yuan center consistent with the center of rolled steel tube.
