Description
Technical field
The present invention relates to the supporting technical field of mold of cold roll forming milling train, particularly a kind of screw rod adjustable mould rotating frame.
Background technology
The section bar of the band shape of various cross section that what cold roll forming mill milling went out is, can cut off section bar with knife edge die during production as required.But all kinds of profile shapes that mill milling goes out are due to stress asymmetry problem, its cross section is not definitely smooth, sometimes has a small amount of distortion, even if also cannot ensure to turn round scarcely through overcorrection.And the cavity dimension of knife edge die is very narrow for section bar, so section bar slightly distortion just cannot pass through die cavity smoothly.Therefore need mould suitably to be rotated an angle to adapt to the direction of twist of section bar.The matched cut-out mould of traditional cold roll forming milling train knocks with the push-and-pull of hand or hammer mould is rotated, troublesome poeration, and position location is inaccurate, fine setting is also inconvenient; Also worm gear mixed by the mould had, worm screw makes its mold rotation, but structure relative complex, and processing, installation workload are relatively large, and cost is also higher.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide that a kind of structure is simple, easy to use, accurate positioning, fine setting easily, process simple, low-cost screw rod adjustable mould rotating frame.
Object of the present invention is achieved through the following technical solutions: a kind of screw rod adjustable mould rotating frame, it comprises mold, it also comprises base plate, carrying bolt and adjusting device, on described two ends, mold left and right and with die cavity center for the center of circle is respectively arranged with elliptical aperture I in circular shape and elliptical aperture II, the upper surface of described base plate is provided with two base seat support A perpendicular to base plate and base seat support B, one end of mold is fixed on base seat support A through elliptical aperture I and base seat support A successively through mould fastening bolt I, the other end of mold is fixed on base seat support B through elliptical aperture II and base seat support B through mould fastening bolt II successively, described adjusting device is by left-handed slip-knot bolt, dextrorotation slip-knot bolt, sleeve pipe and nut composition, sleeve pipe upper, lower two ends are provided with nut, one end of dextrorotation slip-knot bolt is hinged on base seat support B, the end of thread of dextrorotation slip-knot bolt is connected with the nut being arranged on its lower end, one end of left-handed slip-knot bolt is hinged on mold, the end of thread of left-handed slip-knot bolt is connected with the nut being arranged on sleeve upper end, described carrying bolt passes base plate and contacts with mold.
Described dextrorotation slip-knot bolt and the pin joint of base seat support B are arranged on the top of base seat support B.
Described carrying bolt is connected with locking nut, and locking nut is arranged on the below of base plate.
Described elliptical aperture I and elliptical aperture II is symmetrical arranged.
The present invention has the following advantages: on two ends, (1) mold left and right of the present invention and with die cavity center for the center of circle is respectively arranged with elliptical aperture I in circular shape and elliptical aperture II, carrying bolt passes base plate and contacts with mold, therefore, when mold rotates, the contact point of mould fastening bolt I, mould fastening bolt II and carrying bolt and mold is in on the circle that is the center of circle of die cavity center all the time, namely mold is with its central rotation, make use of three-point fix, there is the feature of accurate positioning.(2) adjusting device is provided with between base seat support B of the present invention and mold, when needs mold rotates, only need unscrew or tighten the nut of sleeve pipe upper/lower terminal, to change the distance between left-handed slip-knot bolt and dextrorotation slip-knot bolt, thus make mold do counterclockwise or rotate clockwise an angle to adapt to the direction of twist of section bar, realize fine setting, and without the need to installing turning cylinder for mold, thus simplify the structure, have and finely tune feature that is easy, low cost of manufacture.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of screw rod adjustable mould rotating frame, it comprises mold 1, it also comprises base plate 2, carrying bolt 3 and adjusting device, on described mold about 1 two ends and with mold 1 for the center of circle is respectively arranged with elliptical aperture I4 in circular shape and elliptical aperture II5, elliptical aperture I4 and elliptical aperture II5 is symmetrical arranged, the upper surface of described base plate 2 is provided with two base seat support A6 perpendicular to base plate 2 and base seat support B7, one end of mold 1 is fixed on base seat support A6 through elliptical aperture I4 and base seat support A6 successively through mould fastening bolt I13, the other end of mold 1 is fixed on base seat support B7 through elliptical aperture II5 and base seat support B7 through mould fastening bolt II14 successively, therefore, when mold 1 rotates, mould fastening bolt I13, mould fastening bolt II14 and carrying bolt 3 and the contact point of mold 1 are in on the circle that is the center of circle of die cavity center all the time, namely mold 1 is with its central rotation, make use of three-point fix, there is the feature of accurate positioning.As illustrated in fig. 1 and 2, adjusting device is by left-handed slip-knot bolt 8, dextrorotation slip-knot bolt 9, sleeve pipe 10 and nut 11 form, sleeve pipe 10 upper, lower two ends are all welded with nut 11, one end of dextrorotation slip-knot bolt 9 is hinged on base seat support B7, dextrorotation slip-knot bolt 9 is contrary with the thread rotary orientation direction of left-handed slip-knot bolt 8, the end of thread of dextrorotation slip-knot bolt 9 is connected with the nut 11 being arranged on sleeve pipe 10 lower end, dextrorotation slip-knot bolt 9 is arranged on the top of base seat support B7 with the pin joint of base seat support B7, one end of left-handed slip-knot bolt 8 is hinged on mold 1, the end of thread of left-handed slip-knot bolt 8 is connected with the nut 11 being arranged on sleeve pipe 10 upper end, therefore, when needs mold 1 rotates, only need unscrew or tighten on sleeve pipe 10, the nut 11 at lower two ends, to change the distance between left-handed slip-knot bolt 8 and dextrorotation slip-knot bolt 9, thus make mold 1 do counterclockwise or clockwise rotation, and without the need to installing turning cylinder for mold 1, thus simplify the structure, there is fine setting easily, the feature of low cost of manufacture.As shown in Figure 1, carrying bolt 3 passes base plate 2 and contacts with mold 1, and carrying bolt 3 is connected with locking nut 12, locking nut 12 is arranged on the below of base plate 2, when tightening or unscrew locking nut 12, the contact position of carrying bolt 12 and mold 1 can be regulated.
The course of work of the present invention is as follows: when needs mold rotates, first mould fastening bolt I13, mould fastening bolt II14 and carrying bolt 3 is unscrewed, unscrew or tighten the nut 11 of sleeve pipe 10 upper/lower terminal again, to change the distance between left-handed slip-knot bolt 8 and dextrorotation slip-knot bolt 9, thus make mold 1 do counterclockwise or clockwise fine rotation angle to adapt to the direction of twist of section bar, then tighten locking nut 12 on mould fastening bolt I13, mould fastening bolt II14 and carrying bolt to be fixed by mold 1.
