Description

Technical Field

[0001] The utility model belongs to the technical field of high-temperature material transportation, and in particular relates to a transmission rack component for high-temperature workpieces. Background Art

[0002] In the manufacturing process of many workpieces, the blanks usually need to go through two processes, forging and heat treatment, after being cut. For example, after the sleeve blank is formed by high-temperature forging, it also needs heat treatment to maintain the mechanical durability of the workpiece. However, the workpiece formed by high-temperature forging usually has high-temperature residual heat. If it can be transported to the heat treatment equipment for heat treatment in time, the heating energy consumption of the heat treatment can be greatly reduced. However, workpieces with high-temperature residual heat are usually not convenient for large-scale timely transportation and transfer.

[0003] In the prior art, the patent document with the announcement number CN 103612866 A discloses a monorail synchronous conveying mechanism, a conveying assembly line and a conveying method for workpieces. The monorail synchronous conveying mechanism includes a horizontal displacement device and a lifting device, and the lifting device lifts the horizontal displacement device to rise or fall; the horizontal displacement device includes a frame connected to the lifting device, a driving device arranged on the frame and a linear slide rail for carrying the workpiece, and the driving device drives the linear slide rail to move back and forth on the frame. The above scheme uses a belt to drive the linear slide rail to move back and forth, but it is still not suitable for long-distance transmission of high-temperature workpieces. The temperature will accumulate and be transferred to the belt through the linear slide rail, causing the belt to be damaged or melted and bonded, with a short service life and low efficiency.
