Description

An online inertial vertical turning device for slender objects

technical field

The invention relates to the technical field of improving the structure of an automatic turning device for producing elongated articles, in particular to an inertial vertical turning device for elongated articles.

Background technique

During the production process, the steel pipes are automatically cut to length, and are mainly conveyed by rollers to complete multiple processes, and finally to the wide area of the environment for bundling, which is convenient for loading and unloading. When the longitudinal conveying is transferred to the transverse conveying, a pipe turning device is provided. When the two raceways are parallel at the same time, the steel pipe on the outer track needs to be raised vertically to a certain height, and then the steel pipe falls on the inclined beam below, and the inclined beam crosses the inner roller table, and the steel pipe rolls down from the inclined beam to the horizontal conveying device . The function of the pipe turning device is mainly to automatically turn the steel pipes conveyed by the upper raceway onto the traversing platform and transfer them to the lower raceway, and then the lower raceway will continue to convey the steel pipes downwards, and through the lower turning device, the steel pipes Turn over the stand and transfer to the baling rack for baling.

The weight of each 6-inch steel pipe with a wall thickness of 4mm is about 110 kg. It can be imagined that the inertial momentum moving at a speed of 0.1-0.5 m/s is very large. Such a large inertial momentum is often wasted on the collision plate opposite the roller table. On the contrary, the existing technology relies on mechanisms such as motors or cylinders to realize the turning action to realize the transfer from longitudinal conveying to transverse conveying.

In the prior art, hydraulic pressure, air pressure, and electric power are often used to realize the pipe turning action. CN203804661U of Tianjin Zhaolida Steel Tube Co., Ltd. discloses a material turning device that uses a motor to provide turning power. Long-term use requires maintenance of the motor and reducer.

There are also those that rely on inertial force to realize the tube turning action. As CN202864412U discloses a square tube automatic material turning device, the steel pipe is conveyed in a straight line and bumps into the force plate 5, and the force plate 5 rotates to drive the force axle frame 3 to rotate clockwise, that is, end. The drive rod at the top drives the steel wire to move backwards, and the backward movement of the steel wire rope is converted into a drive rod 7 and a tube plate 9 connected to the steel wire rope to rotate around the tube bracket 8 to move the steel pipe laterally. The above-mentioned stressed shaft frame 3 converts the inertial force into a rotational force, and the rotational force is converted into a backward winding force of the steel wire rope, and the backward winding force drives the pipe removal shaft frame 8 to rotate, which is converted into a horizontal pipe removal force. The above-mentioned rotational force It needs to be converted into the winding force of the steel wire rope, but the force of driving forward and backward driven by the rigid force transferred to the steel wire rope will be partially offset by the tension of the steel wire rope, and the power loss should be limited. What it finally realizes is the action of pushing the tube horizontally.
