Embodiment Construction

[0028] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0029] As shown in the figure, a conveying system for a cylindrical workpiece in a furnace includes a slightly inclined track unit 1, a workpiece positioning unit 2, a steel puller unit 3 and a driving device 4 corresponding to the workpiece positioning unit 2 one by one. The steel pulling machine unit 3 is arranged at the front and rear ends of the slightly inclined track unit 1. When entering the furnace, the front steel rolling machine unit 3 transfers the cylindrical workpiece from the furnace roller table to the slightly inclined track unit 1 by means of the steel pulling machine. When coming out of the furnace, the back-end steel pulling machine unit 3 shifts the...

Abstract

The invention discloses an intra-furnace conveying system for a cylindrical workpiece and a conveying method of the intra-furnace conveying system and belongs to the technical field of furnace body fittings. The conveying system comprises a micro-inclined rail unit, workpiece positioning units, steel pushing machine units and driving devices, which are arranged in a furnace; the driving devices correspond to the workpiece positioning units one by one; the steel pushing machine units are arranged at the front and back ends of the micro-inclined rail unit; the workpiece positioning units are arranged beside the micro-inclined rail unit at equal intervals; each workpiece positioning unit comprises at least two odd positioning units and at least two even positioning units; the odd positioning units and the even positioning units are respectively in parallel with the workpiece in a row and are arranged in a staggered manner; each driving device is arranged between the corresponding odd positioning unit and the corresponding even positioning unit; the conveying method comprises a furnace entering process, a conveying process, a separating and positioning process, and a furnace discharging process. With the intra-furnace conveying system for the cylindrical workpiece and the conveying method, a thermal processing furnace system is simplified substantially, the cost is greatly reduced, and the thermal efficiency of the furnace body and the thermal processing quality of the workpiece are improved.

Description

technical field [0001] The invention belongs to the technical field of furnace accessories, and relates to a conveying system and a conveying method for cylindrical workpieces in a furnace. Background technique [0002] The existing conveying system for cylindrical workpieces in heat treatment furnaces and heating furnaces, such as round pipes, shafts, and round rods, uses a toothed walking beam system to support and convey cylindrical workpieces. The walking beam system is fixed in n rows Beams and n rows of movable beams. Under normal circumstances, the workpiece is placed on the fixed beam. The movable beam is used to lift the workpiece and move it forward. The movable beam is driven by the hydraulic system and the furnace bottom mechanical system to complete the "rise-translation forward-down —The movement trajectory of “translational retreat” is to achieve the purpose of conveying the workpiece forward, but there are the following problems: [0003] 1) Both the fixed b...
