Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed wire rolling mills, and in particular relates to a high-speed wire and bar direct-drive rolling mill. Background Art

[0002] The rolling process of high-speed wire rod includes rough rolling process, pre-finishing rolling process and finishing rolling process. The rolling mill used in each rolling process (such as Figure 1 The rolling mill (as shown in the figure) is composed of a motor mechanism 1, a speed change mechanism 2, a gear box 3 fixed with a bevel gear pair 4, a driven shaft 32, and an idler shaft 31, and a roll box 5 fixed with left and right roll shafts 51 and 52 for rolling the wire rod. Its working principle is that the power motor 1 drives the bevel gear pair 4 in the bevel wheel box through the gearbox 2, and then the bevel gear pair drives the driven shaft 32 and the idler shaft 31, thereby driving the left and right roll shafts 51 and 52 in the roll box to realize the online rolling of the wire rod. The rolling mill of this structure is not only large in size, complex in structure, low in transmission efficiency and high in failure rate, but also has extremely high energy consumption due to the presence of a very large gearbox and bevel gears. Utility Model Content

[0003] The utility model aims to provide a high-speed line and bar direct-drive rolling mill with simple structure, low equipment failure rate and high transmission efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A high-speed wire and bar direct-drive rolling mill, whose structure includes a motor mechanism, a gear box provided with a passive shaft and an idle shaft, and a roll box provided with a left roll shaft and a right roll shaft for driving the online rolling of wires and bars; it is characterized in that: the motor mechanism is fixed in the gear box, and its output shaft is directly connected to the passive shaft to drive its rotation.

[0006] Compared with the prior art, the high-speed wire and bar direct-drive roller box provided by the utility model can realize high-speed rolling of wires and bars because the passive shaft constituting the high-speed wire and bar direct-drive rolling mill is directly driven by the motor mechanism, and the passive shaft drives the left and right rolling rollers through the idle shaft meshing therewith; the bevel gear box and the bulky gearbox in the prior art are omitted, the box structure is greatly simplified, and the rolling efficiency of high-speed wires and bars is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a structural schematic diagram of a rolling mill in the prior art;

[0008] Figure 2 This is a schematic structural diagram of a high-speed line and bar direct-drive rolling mill provided by the utility model. DETAILED DESCRIPTION

[0009] The structure and working principle of a high-speed wire and bar direct-drive rolling mill provided by the utility model will be further described in detail below in conjunction with the accompanying drawings.

[0010] like Figure 2 The figure shows a schematic diagram of the structure of a high-speed wire and bar direct-drive rolling mill provided by the utility model. The structure of the high-speed wire and bar direct-drive rolling mill includes: a gear box 34 and a roll box 5, in which a left roll shaft 51 and a right roll shaft 52 capable of realizing online rolling of wire and bar are fixed in the roll box 5, an idle shaft 31 and a driven shaft 32 fixed in the gear box 3 are respectively meshed with the left roll shaft 51 and the right roll shaft 52, and a motor mechanism 1 is fixed in the gear box, and its rotating shaft 11 is directly fixedly connected with the driven shaft 32.

[0011] Its working principle is that when the high-speed wire and bar are used to directly drive the rolling mill to roll the wire and bar, the motor mechanism is started, and the motor mechanism directly drives the passive shaft and the idle shaft meshing therewith to rotate together, and the passive shaft and the idle shaft directly drive the left roller shaft 51 and the right roller shaft 52 to rotate towards each other at the same time, thereby completing the rolling of the high-speed wire and bar.
