Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, and in particular to a billet turning mechanism utilizing a billet transport chain. Background Technology

[0002] The tandem three-roll mill is the main rolling equipment for special-purpose and large- and medium-sized profiles. Due to the requirements of the rolling process, a chain conveyor is needed to transport the billet to the designated position, and then the billet is flipped by a turning machine to be introduced into the roll pass. Because the turning mechanism is driven by hydraulic means and the actuator is complex, the transmission efficiency is low. Moreover, if the hydraulic oil leaks, serious safety accidents can easily occur at the hot rolling temperature. Utility Model Content

[0003] The main purpose of this invention is to provide a billet turning mechanism that utilizes a billet transport chain, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A billet turning mechanism utilizing a billet transport chain includes a billet receiving claw, a follow-up transport trolley, a transport trolley guide groove, limiting baffles, a counterweight, and a counterweight block. The billet receiving claw and the follow-up transport trolley are connected by a rotating shaft. The follow-up transport trolley is located inside the transport trolley guide groove. The bottom ends of the counterweight and the billet receiving claw are connected by a steel rope. There are two limiting baffles, which are located on both sides of the counterweight. The counterweight block is connected to the follow-up transport trolley via a fixed pulley and a steel rope.

[0006] Preferably, its power source is a steel billet transport chain.

[0007] Preferably, the opening size of the steel-turning receiving claw is larger than the cross-sectional size of the steel billet, and the opening of the steel-turning receiving claw has a chamfer.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The reduction of the steel turning machine device saves energy and improves rolling and transportation efficiency. At the same time, the elimination of the hydraulic drive device prevents safety hazards caused by oil leakage. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-2 As shown, a billet turning mechanism utilizing a billet transport chain includes a billet receiving claw 1, a follower transport trolley 2, a transport trolley guide 3, a limiting baffle 4, a counterweight 5, and a counterweight block 6. The billet receiving claw 1 and the follower transport trolley 2 are connected by a rotating shaft. The follower transport trolley 2 is located inside the transport trolley guide 3. The bottom ends of the counterweight 5 and the billet receiving claw 1 are connected by a steel rope. There are two limiting baffles 4, which are located on both sides of the counterweight 5. The counterweight block 6 is connected to the follower transport trolley 2 through a fixed pulley and a steel rope.

[0015] Specifically, its power source is the billet transport chain.

[0016] Specifically, the opening size of the steel-turning receiving claw 1 is larger than the cross-sectional size of the steel billet 7, and the opening of the steel-turning receiving claw 1 has a chamfer.

[0017] Working principle:

[0018] The billet 7 is transported to the roller conveyor by the conveyor chain. The position of the conveyor chain is controlled by the electrical PLC and positioned by the master controller. Its power source billet turning mechanism is located between the two sets of conveyor roller conveyors and is arranged at intervals with the conveyor chain. The number of turning mechanisms is determined by the length of billet 7. Multiple sets can be set up and used together. Its power source billet turning mechanism has no other drive mechanism, which saves energy and can be applied to other transverse transport methods.

[0019] Its power source is a billet transport chain, used for transporting transverse billets 7 between two or three rolling mills. The billet receiving claw 1 and the following transport trolley 2 are connected by a rotating shaft. After the billet 7 is transversely moved into the receiving position of the billet receiving claw 1, the following transport trolley 2 moves along it. Figure 2 As shown, the steel billet 7 is flipped by changing the positions of the steel receiving claw 1 (A, B, and C).

[0020] The ends of the hammer 5 and the steel-receiving claw 1 are connected by steel ropes. During the flipping process of the steel-receiving claw 1, the hammer 5 slides up and down between the two limit baffles 4. The counterweight 6 is connected to the follow-up transport trolley 2 through fixed pulleys and steel ropes, which drives the follow-up transport trolley 2 to return to the initial steel receiving position. The steel-receiving claw 1 is simultaneously reset to position A. After the steel-flipping action is completed, the billet 7 is transported to the rolling mill for rolling through the roller conveyor.

[0021] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
