Detailed Description
The following description of the embodiments of the present utility model will clearly and fully describe the technical aspects of the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.
Referring to fig. 1 and 2, the deformer comprises a fixed disc 1, a plurality of groups of deformation assemblies 2 are connected to the fixed disc 1, the deformation assemblies 2 comprise a main frame 21, a deformation roller 22 and a reverse guide wheel 23, wherein the deformation roller 22 and the reverse guide wheel 23 are arranged on the main frame 21, and the main frame 21 is connected to the fixed disc 1.
The deformer with stable deformation in the utility model, the fixed disc 1 is connected with the middle shaft 11 of the tubular machine and rotates together with the middle shaft 11; the diameter a of the deforming roller 22 is 6-7mm, for example 6mm, 6.5mm or 7mm; a mounting shaft 231 is arranged on the main frame body 21 in a penetrating way, a second rolling bearing 232 is sleeved on the mounting shaft 231 in a spline way, and the outer part of the second rolling bearing 232 is connected with a reverse guide wheel 23; an adjustment structure is provided between the second rolling bearing 232 and the main frame body 21.
The spline system can prevent the second rolling bearing 232 from rotating radially relative to the mounting shaft 231, but the second rolling bearing 232 can move axially relative to the mounting shaft 231.
The working principle of the utility model is as follows:
In each deformation assembly 2, the steel cords are wound on the reverse guide wheel 23, pass through the reverse guide wheel 23, then are wound on the deformation roller 22, and after passing through the deformation roller 22, the steel cords processed on the deformation assemblies 2 are wound together, and then enter the next twisting process.
When the steel cord with the diameter of 0.6-2mm is processed, the requirements of the specification and the lay length of the steel cord can be met through the deforming roller 22 with the diameter of 6-7mm, so that the structure of the twisted steel cord is loose, the deformation can meet the requirements, and the requirement of high elongation of products is met.
The fixed disc 1 drives the deformation assemblies 2 on the fixed disc to rotate together, so that the steel cord processed by each deformation assembly 2 can rotate together with the fixed disc 1 before twisting, the twisting is more uniform, the steel cord twisting device is suitable for steel cords with large diameter, high yield strength and high deformation requirement, the back filaments in the twisting process are reduced, and the quality of the steel cord is improved.
Preferably, the deformation assembly 2 is provided with four groups which are uniformly distributed on the fixed disc 1 at 90 degrees, and in the processing process, four steel cords are twisted together, so that the special requirements of 4744HE type steel cords can be met.
Preferably, the main frame 21 is provided with a first rolling bearing 222, and the first rolling bearing 222 is connected to the deforming roller 22. The first rolling bearing 222 can avoid hard friction between the main frame body 21 and the deformation roller 22, avoid the elongation reduction of the steel cord during twisting, avoid the deficiency of the steel cord in forming due to the friction coefficient difference of resistance, enable the deformation roller 22 to generate relatively stable deformation when processing the steel cord, and improve the quality of the steel cord product.
Preferably, both ends of the deforming roller 22 are provided with blocking surfaces 221. The wire jumper is avoided in the course of working to the steel cord, and can not carry out effective deformation. It is further preferred that the diameter of the blocking surface 221 is 2-3mm larger than the diameter of the deforming roller 22.
Preferably, the adjusting structure includes an adjusting lever 24, an adjusting spring 241 and an adjusting nut 242; one end of the adjusting rod 24 is connected with the second rolling bearing 232, and the other end of the adjusting rod penetrates out of the main frame body 21 and is sleeved with the adjusting nut 242 by threads after penetrating out of the main frame body 21; the adjusting lever 24 is sleeved with an adjusting spring 241 at a portion between the second rolling bearing 232 and the main frame 21.
In the normal processing process, the middle of the reverse guide wheel 23 and the middle of the deformation roller 22 are positioned on the same straight line b, and the steel cord passing through the reverse guide wheel 23 can be just positioned at the middle position of the deformation roller 22 after being wound on the deformation roller 22, so that stable deformation occurs, but when the steel degree and the torsion force of the steel cord are relatively large, the steel cord is easy to generate resilience force, so that the steel cord is positioned at the outer edge of the deformation roller 22, slipping easily occurs, deformation size is easily changed, and therefore, the position of the reverse guide wheel 23 needs to be adjusted. Referring to fig. 2, when the adjusting nut 242 is screwed to slide the adjusting lever 24 rightward with respect to the main frame 21, the adjusting spring 241 is compressed, the second rolling bearing 232 moves together with the reverse guide wheel 23 in a direction approaching the main frame 21, and the steel cord passes through the reverse guide wheel 23 and then is wound around the deforming roller 22 on a side approaching the main frame 21, so that the steel cord is prevented from slipping off, and stability is improved. Meanwhile, the precision is relatively high by adjusting the adjusting nut 242.
Preferably, the adjustment structure is provided in two groups, one on each of opposite sides of the second rolling bearing 232.
Preferably, after the mounting shaft 231 passes through the main frame 21, the anti-drop plate 233 is connected to prevent the mounting shaft 231 from sliding into the main frame 21 when the position of the reverse guide wheel 23 is adjusted, so that the reverse guide wheel 23 is not stably mounted.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
