Description

Technical Field

[0001] The utility model belongs to the technical field of steel cord production equipment, and specifically designs an anti-arch height device for steel cord. Background Art

[0002] Steel cord is often used in the production of rubber skeleton materials. A steel cord is usually composed of several strands of steel wires twisted together and is usually stored wound on a spool.

[0003] The arch height of the steel cord is an index reflecting the bending degree of the steel cord in its natural state. After the steel cord is wound on the spool for a period of time, it will undergo bending deformation and its straightness is insufficient. At present, the arch height requirement for most steel cords is not to exceed 20 mm. Directly using steel cords that do not meet the arch height requirement for production will result in internal stress concentration after the finished product is produced. Summary of the Invention

[0004] In order to solve the problem that the steel cord is prone to bending deformation on the spool, which affects its straightness and causes internal stress concentration in the steel cord during use, the utility model provides an anti-arch height device for steel cord. Before the steel cord is wound onto the spool, the steel cord is pre-deformed by bending in the opposite direction of the spool winding direction, and the pre-deformation angle is adjusted according to the characteristics of the steel cord to ensure the arch height requirement of the steel cord.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] An anti-arch height device for steel cord, comprising a moving frame, a pulley, a spool and a steel cord. The moving frame includes a mounting part, a wire-passing part and a winding part. Two limiting holes penetrate through the mounting part up and down. A spool is arranged on one side of the moving frame. The wire-passing part is fixedly arranged on the side of the mounting part away from the spool. The wire-passing part penetrates through a wire-passing hole. One end of the mounting part is fixedly provided with a winding part. A plurality of round holes are opened at the end of the winding part away from the mounting part; A bolt penetrates through one of the round holes. The lower end of the bolt extends out of the corresponding round hole and is threadedly connected with a nut. A bearing is sleeved on the bolt between the nut and the winding part. A pulley is installed on the outer side of the bearing; The steel cord passes through the wire-passing hole, is wound around the pulley and then wound onto the spool. After the steel cord passes through the wire-passing hole, it bypasses the pulley to achieve pre-deformation, and then is wound onto the spool to ensure the arch height requirement of the steel cord.

[0007] Preferably, two limiting columns penetrate through the two limiting holes, and the moving frame moves up and down along the limiting columns, and the lifting and moving of the moving frame is guided by the limiting columns.

[0008] Preferably, the mounting part, the wire-passing part and the winding part are of an integral structure.

[0009] Preferably, the bending direction of the steel cord wound around the pulley is opposite to the bending direction of the steel cord wound around the spool, so as to achieve pre-deformation.

[0010] Preferably, the steel cord forms an angle a when wound around the pulley, and the angle a is an acute angle. The size of a is determined according to the material of different steel cords. By replacing the pulley with a corresponding diameter and adjusting the installation of the pulley on the corresponding round hole, the requirement of the pre-deformation angle a of the steel cord is achieved.

[0011] Preferably, a V-shaped groove is circumferentially formed on the pulley, and the included angle of the V-shaped groove is 60°. The steel cord is wound through the V-shaped groove, and the pre-deformation is achieved by winding the steel cord through the V-shaped groove.

[0012] By the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] 1. According to the product characteristics of the steel cord produced by the present utility model, the anti-arch height pre-deformation angle is calculated. Subsequently, a pulley with a corresponding size is selected and installed at the corresponding round hole position. Then, before the steel cord is wound onto the spool, the wire drawing is bent pre-deformed in the direction opposite to the winding direction on the spool, so as to ensure the arch height requirement of the steel cord within a certain natural aging range after winding, and the anti-arch height of the steel cord is achieved.

[0014] 2. The present utility model uses a limit post to ensure the lifting and guiding of the moving frame and the pulley, ensuring that while achieving the anti-arch height pre-deformation, it does not affect the accurate wire arrangement of the steel cord. The structure is simple, and the installation and disassembly are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] As Figures 1 to 4 shown, this embodiment provides a steel cord reverse camber device, which includes a moving frame, a pulley 1, a spool 2, and a steel cord 3. The moving frame includes an installation part 4, a wire passing part 5, and a winding part 6. The installation part 4, the wire passing part 5, and the winding part 6 are of an integral structure. Two limiting holes 7 penetrate through the installation part 4 up and down. A spool 2 is arranged on one side of the moving frame, and the steel cord 3 is wound on the spool 2. Both of the two limiting holes 7 are sleeved and penetrated with limiting columns 16, and the moving frame moves up and down along the limiting columns 16. The lifting and moving of the moving frame is limited by the limiting columns 16. The moving frame is connected to a lifting mechanism with a lifting function to realize the reciprocating lifting and moving of the moving frame.

[0022] On the side of the installation part 4 away from the spool 2, a wire passing part 5 is fixedly arranged. A wire passing hole 9 penetrates through the wire passing part 5. One end of the installation part 4 is fixedly provided with a winding part 6. The steel cord 3 passes through the wire passing hole 9 to reach the winding part 6. A plurality of round holes 10 are opened at one end of the winding part 6 away from the installation part 4. A bolt 11 penetrates through one of the round holes 10. The lower end of the bolt 11 extends out of the corresponding round hole 10 and is threadedly connected with a nut 12. A bearing 13 is sleeved on the bolt 11 between the nut 12 and the winding part 6. A pulley 1 is installed on the outer side of the bearing 13. The steel cord 3 is wound around the pulley 1 and then wound on the spool 2. The bending direction of the steel cord 3 wound around the pulley 1 is opposite to the bending direction of the steel cord 3 wound on the spool 2. The reverse bending pre-deformation of the steel cord 3 compared with the winding direction on the spool 2 is realized through the pulley 1, thereby realizing the reverse camber.

[0023] A V-shaped groove 14 is circumferentially opened on the pulley 1. The included angle of the V-shaped groove 14 is 60°. The steel cord 3 is wound through the V-shaped groove 14. By means of the V-shaped groove 14, when the steel cord 3 is wound through the pulley 1, the steel cord 3 is limited to prevent it from falling off the wheel.

[0024] As Figure 1 shown, the steel cord 3 passes through the wire passing hole 9, is wound around the pulley 1, and is wound on the spool 2. The steel cord 3 forms an included angle a when wound around the pulley 1. The included angle a is an acute angle.

[0025] During use, first, according to the characteristics of the steel cord to be produced, calculate the size of the required angle a, and then determine the size of the required pulley 1 and install it on the corresponding round hole 10. Subsequently, the steel cord 3 passing out of the wire passing hole 9 is wound around the V-shaped groove 14 of the pulley 1, and after winding, it is wound on the spool 2, ensuring that the bending direction of the steel cord 3 wound around the pulley 1 is opposite to the bending direction of the steel cord 3 wound on the spool 2 to realize the reverse camber.

[0026] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent shall be included within the scope of the patent application of the present invention.
