Description

Technical Field

[0002] At present, most of my country's steel forming technology is in the cold single-stream processing, and hot double-stream processing has not yet appeared. The steel forming process is complex and the equipment is single. The existing adjustable guide device has a complex structure and many actuators, which is not economical.

[0003] Therefore, according to the shortcomings of the guide device in the field of hot forming of steel plates at this stage, it is necessary to design a guide device for double-flow hot forming with fewer driving mechanisms. Utility Model Content

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A multi-degree-of-freedom hot steel plate guiding device comprises an outer frame, an upper platform disc adjusting mechanism, a lower platform disc adjusting mechanism and a base adjusting mechanism, wherein the outer frame is installed above the base adjusting mechanism so that the height and the tilt angle of the outer frame can be adjusted by the base adjusting mechanism, the upper platform disc adjusting mechanism and the lower platform disc adjusting mechanism are installed inside the outer frame, and the upper platform disc adjusting mechanism is arranged above the lower platform disc adjusting mechanism;

[0007] The upper platform disc adjustment mechanism comprises an upper guide rod, an upper left first guide roller system, an upper left second guide roller system, an upper right first guide roller system, an upper right second guide roller system and an upper spiral disc, wherein the upper guide rod passes through the outer frame, the upper left first guide roller system, the upper left second guide roller system, the upper right first guide roller system and the upper right second guide roller system are all slidably mounted on the upper guide rod, and are all spirally connected with the upper spiral disc rotatably mounted in the outer frame, and the upper left first guide roller system and the upper left second guide roller system are symmetrically arranged with the upper right first guide roller system and the upper right second guide roller system;

The lower left first guide roller system and the lower left second guide roller system are symmetrically arranged with the lower right first guide roller system and the lower right second guide roller system.

[0009] Further, the base adjustment mechanism includes a front screw elevator, a rear screw elevator, a rear height adjustment bevel, a front height adjustment bevel and a base, the rear height adjustment bevel and the front height adjustment bevel are respectively installed on the front and rear sides of the base, the front screw elevator is connected to the front height adjustment bevel to drive the front height adjustment bevel to move along the axial direction of the guide rod, and the rear screw elevator is connected to the rear height adjustment bevel to drive the side height adjustment bevel to move along the axial direction of the guide rod;

[0010] A first oblique wedge matched with the rear height adjustment oblique wedge and a second oblique wedge matched with the front height adjustment oblique wedge are also provided at the bottom of the outer frame.

[0011] Furthermore, the upper spiral disk and the lower spiral disk are coaxially arranged and connected to the same driving shaft.

[0012] Furthermore, the upper platform disc adjustment mechanism also includes an upper outer guide connecting plate, and the upper outer guide connecting plate is composed of two pieces, which are respectively used to connect the upper left guide roller system and the upper right guide roller system with the upper spiral disk in a spirally movable manner.

The key is that the symmetrically arranged upper left guide roller system and the upper right guide roller system can be adjusted to perform axial adjustment in the same direction or in the opposite direction at the same time through the clockwise or counterclockwise rotation of the upper spiral disk. The movement error of the symmetrically arranged upper left guide roller system and the upper right guide roller system is very small compared with the traditional single axial adjustment mechanism, which has the significance of high-precision adjustment. And the same proportion adjustment of steel plates of different specifications and sizes can be performed through the different specifications of the spiral groove on the upper spiral disk.

[0015] Furthermore, the lower platform disc adjustment mechanism also includes a lower outer guide connecting plate, and the lower outer guide connecting plate is composed of two pieces, which are respectively used to connect the lower left guide roller system and the lower right guide roller system with the lower spiral disk in a spirally movable manner.
