Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
According to the description of fig. 1-4:
the utility model provides a cross wedge rolling axle type spare roll-in straightener for mould, includes:
the base 1 comprises supporting legs 11 respectively arranged at the bottom ends, and each supporting leg 11 comprises an adjusting screw 111, an adjusting nut 112 and an adjusting base 113 which are arranged from top to bottom;
the transmission group 2 is arranged at the right end of the top of the base 1 and comprises a transmission fixing frame 21, a speed reducer 22, a main motor 23 and a transmission belt 24, the speed reducer 22 and the main motor 23 are embedded in the transmission fixing frame 21 from bottom to top, the speed reducer 22 is connected with the main motor 23 through the transmission belt 24, the transmission fixing frame 21 comprises a bottom end connecting bottom plate 211, and the speed reducer 22 comprises a coupler 221 arranged at the left end;
the roll set 3 is arranged at the left end of the transmission set 2 and comprises a roll connecting arm 31, an upper roll 32, a lower roll 33, a bearing 34, a fastening clamp spring 35 and a synchronous telescopic rod 36, wherein the upper roll 32 and the lower roll 33 are arranged in the roll connecting arm 31 from top to bottom through the bearing 34, the left and right mirror images of the roll connecting arm 31 are arranged, the left roll connecting arm 31 comprises a movable shaft hole 311 arranged at the face end, the movable shaft hole 311 comprises a shaft hole ring pad 3111 arranged inside the upper roll hole and the lower roll hole 33, the fastening clamp spring 35 is respectively clamped and embedded at the left end of the upper roll 32 and the lower roll hole 33, the lower roll 33 comprises a lower roll shaft end 331 arranged from right to left, a pushing convex ring 332 and a pushing telescopic rod 333, and the synchronous telescopic rod 36 is respectively arranged in the movable shaft hole 311.
Because the pushing telescopic rod 333 and the synchronous telescopic rod 36 are both hydraulic rods and the telescopic rates of the pushing telescopic rod 333 and the synchronous telescopic rod 36 are set in proportion, before the user uses the utility model, a corresponding program parameter is set in proportion according to the telescopic rods in advance by an external control system, then the pushing telescopic rod 333 and the synchronous telescopic rod 36 are synchronously controlled to extend or contract by the control system, then the lower roller 33 is driven by the pushing telescopic rod 333 to stretch and jack through the pushing convex ring 332 and the bearing 34 at the left end of the lower roller 33 is driven by the synchronous telescopic rod 36 to stretch and jack, so that the lower roller 33 moves left and right in the bearing 34 according to the stretching and jack of the synchronous telescopic rod 36 and the pushing telescopic rod 333, thereby realizing the axial adjustment of the roller, because the axial adjustment only has one group of telescopic rods for driving, the utility model adopts the arrangement of the synchronous telescopic rod 36, when the telescopic rod drives the lower roller 33 to move left and right axially, the bearing 34 moves left and right, so that the problem that when the lower roller 33 is driven to move left and right, the end head at the left end of the lower roller 33 protrudes out of the bearing 34 too much to cause up-and-down shaking, and normal driving use is influenced is prevented.
Because the inner diameter of the shaft hole ring pad 3111 is equal to the outer diameter of the left end of the synchronous telescopic rod 36, and the shaft hole ring pad 3111 is made of rubber, when a user uses the synchronous telescopic rod device, the synchronous telescopic rod 36 can be driven to extend and retract in the moving shaft hole 311 through the equal diameters, so that the phenomenon of movement deviation can not occur, and the moving shaft hole 311 is prevented from being directly contacted with the synchronous telescopic rod 36 to cause abrasion through the use of the rubber.
When a user uses the utility model, the ground on which the utility model is placed cannot be completely horizontal, which causes the phenomenon that the utility model is placed in an unstable horizontal state, thereby causing the phenomenon that the lower roller 33 is unbalanced in processing.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
