Description

Technical Field

[0001] This utility model relates to a heat-protected billet pushing device, belonging to the field of billet pushing technology in the metallurgical industry. Background Technology

[0002] Steel billets are products obtained by casting molten steel produced in a steelmaking furnace, primarily used in the production of steel products and various steel goods. From a manufacturing process perspective, steel billets can be mainly divided into ingot-cast billets and continuously cast billets. In hot rolling, steel billets are one of the main raw materials, possessing physical properties including high density, high strength, excellent mechanical properties, weldability, machinability, and good toughness and plasticity. These characteristics make steel billets easy to process during rolling and allow them to maintain stable product shape and dimensions. After processing, steel billets need to be conveyed, requiring the use of steel billet pushing devices.

[0003] Chinese patent (CN105964961B) discloses a billet guiding and conveying device for a continuous casting machine, comprising: a frame, in which several conveying rollers are arranged sequentially and at intervals along the billet's forward conveying direction, forming a billet conveying platform for receiving and conveying the billets; several fixed cover plates arranged at left-right intervals are arranged on the frame between each pair of adjacent conveying rollers, forming several rows of fixed cover plate groups arranged at left-right intervals; a billet guiding and conveying channel is formed between each pair of adjacent fixed cover plates in each row of fixed cover plates; and a detachable movable cover plate is arranged between each pair of adjacent fixed cover plates in each row of fixed cover plates, with the movable cover plate positioned directly above the corresponding conveying roller. This device has the advantages of high safety and improved maintenance efficiency of the conveying rollers. While current billet conveying devices can transport billets, some problems still exist in practical applications. The main issue is that due to the high overall temperature of the billets, they inevitably radiate a significant amount of heat to the surrounding area during transport. This heat accumulates on the drive structure, causing thermal damage over time, leading to frequent equipment failures and poor performance. Therefore, there is an urgent need for a thermally protected billet pushing device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a heat-protected billet pushing device that not only ensures stable transmission of the billet but also provides good thermal protection for the drive structure. Furthermore, it enables real-time circulation and exchange of the cooling medium, thereby continuously ensuring thermal protection for the drive structure, improving the equipment's service life, reducing its failure rate, and solving the problems existing in the background technology.

[0005] The technical solution of this utility model is:

[0006] A heat-protected billet pushing device includes a mounting frame, a support bracket, a stroke groove, a billet pushing mechanism, a bearing plate, a heat protection component, and a pushing drive mechanism. A bearing plate is horizontally fixed between two mounting frames. A stroke groove is provided on the top surface of the bearing plate. A support bracket is provided under each mounting frame. The billet pushing mechanism is slidably installed inside the stroke groove. The billet pushing mechanism includes a movable block slidably installed inside the stroke groove and multiple billet pushing paddles fixedly installed on both outer walls of the movable block. A heat protection component that cooperates with the billet pushing mechanism and a pushing drive mechanism for the billet are provided on one outer wall of the mounting frame. The pushing drive mechanism includes a pushing motor, a mounting shaft, a mounting roller, and a pressure fan. The pushing motor is fixedly installed on one outer wall of the mounting frame. A mounting shaft is fixedly installed at one end of the output shaft of the pushing motor, and a mounting roller and a pressure fan are fixedly installed outside the mounting shaft.

[0007] One end of the billet pushing blade is slidably connected to the outer surface of one side of the two mounting brackets. There is a mounting side groove between two adjacent billet pushing blades. Several meshing teeth are fixedly installed on the bottom surface of the moving block.

[0008] The mounting side groove is equipped with a side pressure positioning component that cooperates with the steel billet.

[0009] The side-pressure positioning assembly includes a positioning plate and a side-positioning spring. The side-positioning spring is fixedly installed on the inner wall of one side of the mounting side groove, and the positioning plate is fixed to one end of the side-positioning spring.

[0010] A drive gear ring is fixedly mounted on the outer side of the mounting roller, and the drive gear ring meshes with the meshing teeth.

[0011] The thermal protection component includes a coolant tank and a thermal protection box. The thermal protection box is fitted outside the push motor. An inner mounting groove is provided inside the thermal protection box, and a coolant sleeve is embedded in the inner mounting groove. Both the coolant tank and the thermal protection box are lined with heat insulation material.

[0012] The coolant tank is fixedly installed on one side of the outer wall of the mounting bracket. A circulating liquid pump is fixedly installed inside the coolant jacket. An inlet pipe and an outlet pipe are fixedly installed on one side of the outer wall of the circulating liquid pump. An inlet port and an outlet port are provided on one side of the outer wall of the coolant jacket.

[0013] One end of each of the inlet and outlet pipes passes through the thermal protection box and is fixedly connected to the inlet and outlet. An external coolant interface is provided on the other side of the coolant tank, and a conduit is horizontally fixedly installed on the rear side of the coolant tank.

[0014] A switch panel is fixedly installed at one end of the conduit. A pressure switch that works with the circulating liquid pump is provided on one side of the outer surface of the switch panel. The pressure switch is located on one side of the pressure fan.

[0015] The beneficial effects of this utility model are:

[0016] (1) By setting up a billet pushing mechanism and a pushing drive mechanism, when the billet is being transported, the billet is placed between the two billet pushing plates of the billet pushing mechanism. At this time, the pushing motor is turned on, and the pushing motor can drive the installation roller to rotate. The driving gear ring can rotate synchronously, and the driving gear ring can drive the moving block with meshing teeth to move. The billet pushing plates can move synchronously, and can push the billet inside to be transmitted until the billet is pushed to the outside of the bearing plate. At this time, the billet will fall directly into the receiving structure and enter the next process. Through this design, the stable transmission of the billet can be completed. Moreover, this method directly realizes the transmission of hot billet by pushing. It does not generate a large pressure on the outside of the hot billet, and can effectively avoid the deformation of the hot billet.

[0017] (2) By setting up a heat protection component, a large amount of coolant will be filled in the coolant jacket when the equipment is in normal use. This coolant can effectively prevent the push motor from being attacked by continuous high temperature. When the installation roller rotates, the touch fan can also rotate synchronously. The touch fan can press the touch switch of the heat protection component once every one rotation. When the touch switch is pressed once, it will open once. At this time, the coolant in the coolant jacket can be exchanged through the inlet pipe and the outlet pipe, so that the coolant in the coolant jacket can maintain its cooling effect. Through this design, when the equipment is used, it can not only ensure the stable transmission effect of steel billet, but also achieve a good heat protection effect for the drive structure. At the same time, it can realize the real-time circulation exchange of the cooling medium, thereby continuously ensuring the heat protection of the drive structure, improving the service life of the equipment, and reducing its failure rate.

[0018] (3) By providing a side pressure positioning component on the side of the billet pushing mechanism, when the billet is placed on the bearing plate, the side positioning plate can push the billet to the side under the action of the side positioning spring, so that the billet is firmly restricted between the side positioning plate and the mounting frame. In the subsequent billet pushing, the stability of billet pushing can be effectively guaranteed, and the billet can be avoided from shifting, thus ensuring the stable operation of the work.
