Description

Technical Field

[0004] The rolling mill of this kind of equipment has no power driving device, and the winding machine has a power driving device. The wire sent out by the feeding device is rolled by the rolling mill and then wound on the drum of the winding machine under the drive of the power of the winding machine. The change of the cross-sectional shape and size of the wire comes from the power of the winding machine. And because the change of the cross-sectional shape and size of the wire is a gradual process and cannot be drawn and rolled in place at one time, therefore, the forming of special-shaped wires needs to go through a repeated process from rough rolling to finish rolling and from feeding to winding. The production efficiency is low and it is difficult to control the product precision.

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0036] As Figure 1-16As shown in the figure, the embodiments of the present invention include a feeding device 11 for supplying special-shaped wire rod raw materials, a rolling mill group 12 for gradually rolling according to the cross-sectional size of the rolled wire rod, a receiving device 13 for collecting the rolled wire rod, and a sensor detection device 14 for controlling the tension and linear velocity of the wire rod during the rolling process.

The motor structure includes a motor bracket 328, a servo motor 36 arranged on the motor bracket 328, and a small belt pulley 327 arranged at the output end of the servo motor 36. The small belt pulley 327 and the large belt pulley 312 rotate synchronously through a synchronous belt 322. A large belt pulley seat 311 is arranged outside the large belt pulley 312. The large belt pulley 312 is connected to the large belt pulley seat 311 through a rolling bearing 310. An upper bracket is arranged in the upper roll seat 34.

The lower roll 313 is connected to the lower bracket and the lower roll seat 32 through a rolling bearing.

[0037] A sensor detection device 14 is arranged on the rolling mill group 12. The sensor detection device 14 includes several single sensor detection devices, and the single sensor detection devices are arranged in one-to-one correspondence with the single rolling mills.

[0038] Each single sensor detection device includes a bottom plate 212, a vertical plate 211 arranged on the bottom plate 212, and an upper baffle 210 arranged at the top of the vertical plate 211. A linear slide rail 25 and a rack 21 are arranged on the vertical plate 211. A bracket bottom plate 26 is arranged on the linear slide rail 25. A bracket vertical plate 23 is arranged on the bracket bottom plate 26. The bracket vertical plate 23 is connected to a sensor 24. The output shaft of the sensor 24 is connected to a gear 22. The gear 22 meshes with the rack 21. A pulley shaft 27 is arranged on the bracket bottom plate 26. A pulley 28 is arranged on the pulley shaft 27.

[0039] A wire rod positioning structure 15 is arranged on the rolling mill group 12. The wire rod positioning structure 15 includes several single wire rod positioning devices, and the single wire rod positioning devices are arranged in one-to-one correspondence with the single rolling mills.

[0040] The wire positioning device includes a bracket base plate 41, a bracket vertical plate 42 provided at the upper end of the bracket base plate 41, a bracket horizontal plate 43 provided at the upper end of the bracket vertical plate 42, a vertical plate 410 provided at the upper end of the bracket horizontal plate 43, and a bracket top plate 49 provided at the upper end of the vertical plate 410. A fixed seat 411 and a guide rail block 413 fixedly connected to the vertical plate 410 are provided on the vertical plate 410, a sliding seat 48 connected to the guide rail block 413, the bracket top plate 49 is connected to a limit screw 412, a roller shaft II 46 is provided on the sliding seat 48, a roller shaft I 45 is provided on the fixed seat 411, the roller shaft I 45 and the roller shaft II 46 are arranged in parallel, and positioning rollers 44 are provided on both the roller shaft I 45 and the roller shaft II 46.

[0041] The feeding device 11 includes a feeding frame 51, a feeding tray 53 provided at the upper end of the feeding frame 51, and a surrounding rod 52 provided on the feeding tray 53. The surrounding rod 52 is composed of several pieces and is arranged circumferentially on the feeding tray 53.

[0042] The material receiving device 13 includes a transmission box 62, a driving motor 61 provided on one side of the transmission box 62, a main shaft 64 provided in the transmission box 62, a material receiving cylinder 63 provided on the main shaft 64, a reciprocating mechanism 66 provided on the transmission box 62, and a positioning device 65 provided on the reciprocating mechanism 66.

[0043] In this embodiment, the function of the feeding device 11 is to provide the raw material supply of the special-shaped wire, and provide the raw material of the special-shaped wire to the rolling mill for production needs. The rolling mill group 12 is composed of several single rolling mills. According to the different cross-sectional dimensions of the rolled wire, the number of single rolling mills that make up the rolling mill group 12 is also different. After the wire provided by the feeding device 11 is rolled by the first rolling mill, its shape and size are changed, and then it enters the second rolling mill for rolling, and the shape and size of the wire are changed again. In this way, the wire rolled out by the previous rolling mill enters the next rolling mill for rolling, and the cross-sectional shape and size of the wire rolled out by each rolling mill are changed to a certain extent. In this way, the wire rolled out by the last rolling mill reaches the predetermined size requirements. Because there are inevitable manufacturing errors in the rolling equipment itself, and because in the continuous rolling process, as the cross-section of the wire changes, the length of the wire also changes at the same time, so the function of the sensor detection device 14 is to keep the tension of the wire uniform and the linear velocity constant during the rolling process. Finally, the rolled wire is wound around the material receiving cylinder 63 of the material receiving device 13.

[0044] During the continuous rolling process, as the length of the wire rod changes, the sag of the wire rod between the rolling mills also fluctuates up and down. The pulley 28 of the sensor detection device 14 is located above the wire rod. As the wire rod fluctuates up and down, under the action of gravity, the pulley 28 drives the bracket through the pulley shaft 27, thereby driving the sensor 24 connected to the bracket to move up and down along the linear slide rail 25. During the up and down movement, due to the meshing of the gear 22 and the rack 21, the rotating gear 22 causes the sensor 24 to rotate simultaneously. In this way, the sensor 24 plays a role in controlling the servo motor on the rolling mill.

[0045] In the rolling mill, the rolling mill base plate 31 is used to support the components. Grooves are machined on it, and the function of the grooves is to accommodate and discharge the coolant required during the wire rolling process. The bracket 37, the bracket bottom plate 38, the large pulley seat 311, the rolling bearing, the hole retaining ring 323, the shaft retaining ring 424, the large pulley 312, the small pulley 327, the synchronous belt 322, the motor bracket 328 and the servo motor 36 constitute the power transmission device of the rolling mill. On the surfaces of the upper and lower rolling rolls of the rolling mill, grooves adapted to the special-shaped wire rod are respectively machined. The shape and size of the grooves are one of the important factors determining the shape and accuracy of the rolled wire rod. The thickness of the adjustment gasket 33 between the upper and lower rolling roll seats determines the center distance between the upper and lower rolling rolls. After adjusting the thickness of the gasket, the upper and lower rolling roll seats are connected and fastened with the compression bolts 35. The screw rod 316, the screw seat 318 and the steel ball 315 constitute the axial adjustment device of the rolling roll. Adjusting the screw rod 316 can change the axial position of the upper and lower rolling rolls. In addition to bearing the axial force and reducing the frictional resistance, the steel ball 315 can greatly reduce the end face runout of the rolling roll to ensure that the rolling mill has a high rolling accuracy. The upper and lower rolling rolls are supported by rolling bearings. The servo motor 36 transmits the motion and power to the lower rolling roll 313 through the synchronous belt 322 transmission device. Under the pressure of the upper and lower rolling rolls, the special-shaped wire rod is rolled.

[0046] The function of the wire rod positioning device 15 is to determine the relative position of the rolled wire rod with respect to the rolling mill rolls. During the production process, it is ensured that the rolled wire rod among the two wire rod positioning devices located before and after the rolling mill and the rolling mill rolls remains on a horizontal line. Among them, the bracket bottom plate 41, the bracket cross plate 43, the bracket vertical plate 42, and the vertical plate 410 form the frame of the wire rod positioning device. A positioning roller 44 is fixedly connected to the frame through the roller shaft one 45 and the fixed seat 411. The other positioning roller 44 is connected to the guide rail block 413 through the roller shaft two 46. The guide rail block 413 can slide up and down in the sliding seat 48. Grooves adapted to the rolled wire rod are provided on the upper and lower positioning rollers 44. During the production process, the limit screw 412 is adjusted to control the gap between the grooves on the positioning roller 44 and the rolled wire rod.

[0047] The feeding tray 53 of the feeding device 11 is used to place the raw materials of the special-shaped wire. The function of the surrounding rod 52 is to prevent the raw materials of the wire from winding around each other.

[0048] As the name implies, the function of the receiving device 13 is to wind up the rolled special-shaped wire together for use in the next production process. The driving motor 61 transmits motion and power through the transmission box 62. On the one hand, it drives the main shaft 64 to drive the receiving cylinder 63 to rotate. On the other hand, it drives the reciprocating mechanism 66 to make a reciprocating motion. The rolled special-shaped wire is wound around the receiving cylinder 63 through the positioning device 65. Under the action of the rotational motion of the receiving cylinder 63 and the reciprocating motion of the reciprocating mechanism 66, the rolled special-shaped wire is evenly wound around the receiving cylinder 63.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
