Problems solved by technology

[0003] When the three-axis drive rolling mill is rolling, the rolling force is balanced at three angles, and the rolling force of the roll is large. The single three-axis drive rolling mill requires each axis to have an independent power system or use multiple sets of reversing gear boxes. Changing the driving direction, the entire driving module transmission chain is more complicated, and the system cost is also high
[0004] The single-shaft transmission type rolling mill has a simple transmission system, and the rolls in the rolling mill are fixedly installed. The rolls cannot be disassembled quickly without dismantling the frame body. It is too large to achieve the purpose of diameter reduction and sizing; it needs to be repaired after a period of use before using it again
However, when rolling metals with high strength and poor shape, such as

Example Embodiment

[0034] Example

[0035] Such as figure 1 , figure 2 with image 3 As shown, the three-roll rolling mill used in this embodiment is mainly aimed at the rolling of bars, especially the rolling of bars with arc triangle pass and tangential pass. One of the characteristics of the three-high rolling mill of this embodiment is that the transmission structure is simple. One drive shaft drives the other two drive shafts to rotate. There is no complicated transmission structure, simple installation, higher precision, and stable and reliable long-term use; another feature Yes, the disassembly and maintenance are convenient, and the disassembly and installation of the roll 4 can be completed quickly without affecting the accuracy of the work.

[0036] The single-shaft drive roll 4 detachable three-high rolling mill includes a stand 1 and three sets of shaft components arranged at 60° to each other on the stand 1. The stand 1 is a split structure, and the three sets of shaft components inclu...

Abstract

The invention relates to the technical field of bar mills, and provides a single-shaft transmission roller detachable three-high mill. The mill comprises a rack and three shaft assemblies arranged onthe rack, wherein every two shaft assemblies form an angle of 60 degrees, the rack is of a split structure, the three shaft assemblies comprise an input long shaft assembly and two transmission shortshaft assemblies, and the transmission short shaft assemblies are connected with the input long shaft assemblies for transmission. According to the mill, by adopting the split rack, the three-high mill which is simple and reliable in transmission structure is formed by cooperation of the long shaft assembly and the short shaft assemblies, and the investment cost is greatly reduced through the simpler structure; during equipment maintenance, rollers can be quickly disassembled in a quick disassembly manner, the roller dismounting and mounting accuracy are maintained, and remounting and reuse are not affected.

Description

technical field [0001] The invention relates to the technical field of bar rolling mills, in particular to a three-roll bar-wire rolling mill, in particular to a detachable three-roll rolling mill with single-shaft transmission. Background technique [0002] At present, the commonly used bar three-roll mills in the industry include three-axis drive type and single-axis drive type. Two-axis rotation realizes the rolling of bars. [0003] When the three-axis drive rolling mill is rolling, the rolling force of the rolled piece is balanced at three angles, and the rolling force of the roll is large. The single three-axis drive rolling mill requires each axis to have an independent power system or use multiple sets of reversing gear boxes. To change the driving direction, the entire driving module transmission chain is relatively complicated, and the system cost is also high. During equipment installation and maintenance, the three-axis drive type mostly uses pressure to assemb...
