Description

Technical Field

[0001] The utility model relates to a wedge push tracking and resetting mechanism, in particular to a mechanism for tracking and resetting a continuous casting steel billet of a wedge push continuous casting machine forging device, belonging to the technical field of mechanical design and manufacturing. Background Art

[0002] Since continuous casting steel billets have the advantages of short production cycle, large production volume, high production efficiency and high degree of automation, they can better meet the market demand for large-scale, high-quality cast steel billets. However, continuous casting steel billets are prone to central defects such as looseness and shrinkage holes, which become more serious as the diameter of the casting increases. For this reason, people have designed online forging of continuous casting steel billets. Two sets of forging heads are used at the parts where the core of the steel billet is about to crack due to cold shrinkage, and the steel billet casting is squeezed in turn, so that the central defects of the high-temperature continuous casting steel billet are forged in time, thereby maximizing the production specifications of the continuous casting steel billet. However, in actual operation, since the forging head squeezes the continuous casting steel billet while the steel billet is still running, this causes the forging to hinder the operation of the continuous casting steel billet, and the forging and casting processes are not synchronized, which hinders the normal operation of the steel billet. For this reason, the consistency problem of continuous casting and forging must be solved. Summary of the invention

[0003] In response to the problems raised in the background technology, the utility model proposes a wedge-pushing tracking and resetting mechanism for the forging device of a continuous casting machine, and the forging device of the continuous casting machine is arranged on a mechanism that runs synchronously with the continuous casting billet, so that the forging head can run synchronously with the continuous casting billet during forging, thereby eliminating the obstruction of the forging process to the operation of the continuous casting billet itself.

[0004] In order to achieve the above-mentioned purpose, the utility model designs the following technical scheme: a wedge push tracking and resetting mechanism of a continuous casting machine forging device, comprising a continuous casting machine and a forging device, wherein the continuous casting machine comprises a crystallizer and a straightening device, molten steel is cooled in the crystallizer to form a high-temperature continuous casting billet, and the straightening device pulls out the high-temperature continuous casting billet; the forging device comprises a frame and a forging assembly, wherein the forging assembly is fixed on the frame, each forging assembly comprises a hydraulic cylinder and a forging head, wherein the forging head is fixedly connected to the piston rod of the hydraulic cylinder, and radially forges the high-temperature continuous casting billet, and is characterized in that:

[0005] The frame is arranged on a fixed beam.

[0010] The reset component comprises a reset spring, one end of which is fixed on the fixed beam and the other end of which presses the frame. When the forging head returns, the reset spring pushes the frame to reset.

[0011] Preferably, the lower side of the forging head is arranged as an inclined surface, which fits with the inclined surface on the fixed inclined surface body, and a inclined surface sliding pair is formed therebetween.

[0012] Furthermore, when the continuous casting machine is vertical, the sliding seat and the fixed beam form a vertical moving pair.

[0013] Furthermore, when the continuous casting machine is horizontal, the sliding seat and the fixed beam form a transverse moving pair.
