Description

Technical Field

[0001] The utility model belongs to the technical field of steelmaking, and particularly relates to a steel turning mechanism of a steel turning machine for high-strength cold-drawn cylinder steel. Background Art

[0002] In the steelmaking process, a steel turning machine is required. The steel turning machine is a machine that moves the steel billets.

[0003] like Figure 1 The steel turning mechanism of the steel turning machine includes multiple isolation mounting frames 10 (arranged along the vertical screen direction), the mounting frame 10 includes a zone frame 11, and a four-bar linkage is provided between two adjacent isolation mounting frames 10. The four-bar linkage moves in the area corresponding to the zone frame 11. The four-bar linkage includes a sequentially hinged frame, an upper connecting rod 21, a V-shaped support plate 23, and a lower connecting rod 22.

[0004] When it is working, the V-shaped supporting plate 23 is located at a low position (such as Figure 1 State), the upstream steel billet (see reference numeral 91) enters the V-shaped support plate 23 (see reference numeral 92), and the driving cylinder of the four-bar mechanism moves, causing the V-shaped support plate 23 to flip the workpiece to the downstream docking component (see reference numeral 93), and the downstream docking component takes it away. At the same time, the four-bar mechanism returns to its initial position to complete the steel flipping.

[0005] However, sometimes an accident may occur when the V-shaped support plate 23 cooperates with the downstream docking component, and the downstream docking component fails to take away the steel billet. At this time, the steel billet (see reference numeral 94) will roll over the upper connecting rod 21. After the fault is eliminated, if the four-bar linkage continues to move, the steel billet (see reference numeral 94) will be stuck between the upper connecting rod 21 and the left frame of the zone frame 11, thereby blocking the upper connecting rod 21 from rotating, causing damage to the upper connecting rod 21 or the zone frame 11.

[0006] At this time, it is necessary to lift the steel billet (see reference numeral 94 ) stuck between the upper connecting rod 21 and the left frame of the zone frame 11 , which is quite troublesome. Utility Model Content

[0007] The technical problem to be solved by the utility model is: how to design a steel turning mechanism relative to a high-strength cold-drawn cylinder steel turning machine, so that an accident will not occur when the V-shaped support plate cooperates with the downstream docking component, and the upper connecting rod or the zone frame will not be damaged.

[0008] The technical solution of the utility model is specifically as follows:

[0009] A steel turning mechanism of a steel turning machine for high-strength cold-drawn cylinder steel includes at least three isolation mounting frames, the mounting frames include area frames, a four-bar linkage is provided between two adjacent isolation mounting frames, the four-bar linkage moves in the area corresponding to the area frame, the four-bar linkage includes a hinged frame, an upper connecting rod, a V-shaped support plate, and a lower connecting rod. A backflow inclined plate is fixed on the area frame, one end of the backflow inclined plate is fixed to the top of the left frame of the area frame, and the other end is fixed to the bottom frame of the area frame. When the V-shaped support plate is in a low position, the left section of the backflow inclined plate is higher than the left end portion of the V-shaped support plate, so that the steel billet of the backflow inclined plate can enter the V-shaped support plate.

[0010] The zone frame and the backflow inclined plate are both made of metal and are fixed by welding.

[0011] Compared with the existing technology, the technical effect of the present invention is that the present invention is provided with a backflow inclined plate. If an accident occurs when the V-shaped support plate cooperates with the downstream docking component, the backflow inclined plate will backflow the workpiece into the V-shaped support plate without lifting it away and without affecting the normal operation of the four-bar linkage. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the prior art.

[0013] Figure 2 It is a schematic diagram of the present utility model. DETAILED DESCRIPTION

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0015] like Figure 1 A steel turning mechanism of a steel turning machine for high-strength cold-drawn cylinder steel includes at least three isolation mounting frames 10 (arranged along the vertical screen direction), the mounting frame 10 includes a zone frame 11, and a four-bar linkage is provided between two adjacent isolation mounting frames 10. The four-bar linkage moves in the area corresponding to the zone frame 11. The four-bar linkage includes a frame hinged in sequence, an upper connecting rod 21, a V-shaped support plate 23, and a lower connecting rod 22.

[0016] A backflow inclined plate 12 is fixed on the zone frame 11, one end of the backflow inclined plate 12 is fixed to the top of the left frame of the zone frame 11, and the other end is fixed to the bottom frame of the zone frame 11. When the V-shaped support plate 23 is in a low position, the left section of the backflow inclined plate 12 is higher than the left end portion of the V-shaped support plate 23, so that the steel billet on the backflow inclined plate 12 can enter the V-shaped support plate 23.

[0017] For the sake of firmness, the zone frame 11 and the reverse flow inclined plate 12 are both made of metal and are fixed by welding.

[0018] like Figure 1 , its working principle is:

[0019] When it is working, the V-shaped supporting plate 23 is located at a low position (such as Figure 1 State), the upstream steel billet (see reference numeral 91) enters the V-shaped support plate 23 (see reference numeral 92), and the driving cylinder of the four-bar mechanism moves, causing the V-shaped support plate 23 to flip the workpiece to the downstream docking component (see reference numeral 93), and the downstream docking component takes it away. At the same time, the four-bar mechanism returns to its initial position to complete the steel flipping.

[0020] If an accident occurs when the V-shaped support plate 23 cooperates with the downstream docking component, and the downstream docking component fails to take away the steel billet, the steel billet (see reference numeral 94) will flow back through the inclined plate 12 and return to the V-shaped support plate (see reference numeral 94).

[0021] After the fault is eliminated, the four-bar linkage continues to move, and the steel billet (see reference numeral 92 ) does not block the rotation of the upper connecting rod 21 and can be turned over normally.

[0022] Features of this application:

[0023] Compared with the existing technology, the technical effect of the present invention is that the present invention is provided with a backflow inclined plate. If an accident occurs when the V-shaped support plate cooperates with the downstream docking component, the backflow inclined plate will backflow the workpiece into the V-shaped support plate without lifting it away and without affecting the normal operation of the four-bar linkage.

[0024] For other contents, please refer to the prior art.

[0025] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
