Description

Technical Field

[0001] The present invention relates to the technical field of rolling mills, and more specifically, it relates to a metal wire rolling mill with a synchronous heating function. Background Art

[0002] During the hot rolling process of metal wire, the material needs to be heated and then fed into the rolling mill to achieve plastic deformation. In traditional hot rolling processes, gas heating furnaces or electric induction heating devices are generally used to preheat the wire externally.

[0003] In the above-mentioned technical solutions, it is difficult to ensure the temperature of the wire during processing. The temperature may drop rapidly due to the low ambient temperature. To ensure the hot rolling effect, in the prior art, the hot rolling effect is improved by the self-heating of the rolling rolls. However, since the rolling wheels and the wire cannot be in contact at the same position for a long time, it is still impossible to ensure sufficient heating of the wire during hot rolling, and it is difficult to ensure the hot rolling effect.

[0004] Therefore, a new technical solution is urgently needed to solve the above technical problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a metal wire rolling mill with a synchronous heating function.

[0006] The above technical object of the present invention is achieved through the following technical solutions: A metal wire rolling mill with a synchronous heating function includes a base. On the surface of the base, two sets of rolling roll groups are provided. Each rolling roll group includes a connecting block. On both sides of the surface of the connecting block, vertical connecting plates are provided. Between the connecting plates, an upper rolling wheel and a lower rolling wheel are provided. The lower rolling wheel and the upper rolling wheel are made of conductive metal. On both sets of rolling roll groups, conductive connectors electrically connected to the lower rolling wheel or the upper rolling wheel are provided;

[0007] It further includes a driving component for driving the two sets of rolling roll groups to move relatively or away from each other, and an adjusting component for adjusting the distance between the upper rolling wheel and the lower rolling wheel in each set of rolling roll groups.

[0008] The present invention is further provided as follows: A sliding groove is opened on the surface of the base along its length direction. The two connecting blocks are slidably connected in the sliding groove. The driving component includes a lead screw rotatably connected in the sliding groove. The surface of the lead screw is provided with threads with opposite helix directions and is respectively threadedly connected to the two connecting blocks. One end of the base is equipped with a motor for driving the lead screw.

[0009] The present invention is further provided as follows: The upper rolling wheel is rotatably connected between the two connecting plates. The connecting plates are provided with sliding grooves in the vertical direction. Sliding blocks are slidably connected in the sliding grooves. The lower rolling wheel is rotatably connected between the two sliding blocks. The adjusting component is used to adjust the height position of the sliding blocks.

[0010] The present invention is further configured such that: the conductive joint is disposed on one side of the slider, and the slider is made of conductive metal.

[0011] The present invention is further configured such that: the adjusting assembly includes two fixing plates disposed on both sides of the middle of the base surface. Two abutting rods are hinged on the fixing plates. The two ends of the abutting rods facing the base are inclined upward and abut against the bottom of the slider. The adjusting assembly further includes an adjusting member for adjusting the angle of the abutting rods.

[0012] The present invention is further configured such that: the adjusting member includes an adjusting rod disposed on the base surface. The two ends of the abutting rod facing the base are inclined upward and abut against the bottom of the slider. Four grooves corresponding to the four adjusting rods are formed on the base surface along its length direction. A convex block slidably connected to the groove is disposed at the bottom of the adjusting rod. A screw rod is rotatably connected in the groove. The screw rod passes through and is threadedly connected to the convex block. One end of the screw rod extends out of the side wall of the base and is provided with a rotating handle.

[0013] The present invention is further configured such that: the lower surface of the slider is arc-shaped.

[0014] The present invention is further configured such that: the top of the adjusting rod is arc-shaped.

[0015] The present invention is further configured such that: the abutting rod is made of insulating material.

[0016] The present invention has the following beneficial effects: Before processing, the driving assembly drives the two rolling mill groups to move relatively, so that the distance between the two rolling mill groups is relatively close. And the adjusting assembly is used to increase the distance between the upper rolling wheels. Thus, it is convenient to pass the preheated metal wire between the upper and lower rolling wheels of the two groups. Then, the driving assembly drives the two rolling mill groups to move away from each other, and the adjusting assembly is used to reduce the distance between the upper and lower rolling wheels, and finally press the metal wire tightly. Finally, by connecting the two conductive joints to a power source, the current is conducted through the metal wire, and the metal wire generates heat under the action of its own resistance, thereby ensuring its hot rolling effect.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0023] As shown in the figure, a metal wire rolling mill with a synchronous heating function includes a base 1. Two sets of roller sets 2 are arranged on the surface of the base 1. The roller set 2 includes a connecting block 3. Vertical connecting plates 4 are arranged on both sides of the surface of the connecting block 3. An upper roller 5 and a lower roller 6 are arranged between the connecting plates 4. The lower roller and the upper roller are made of conductive metal. Conductive joints 7 electrically connected to the lower roller or the upper roller are arranged on both sets of roller sets 2.

[0024] It further includes a driving assembly for driving the two sets of roller sets 2 to move relatively or away from each other, and an adjusting assembly for adjusting the distance between the upper roller and the lower roller in each set of roller sets 2.

[0025] Before processing, the two sets of roller sets 2 are driven to move relatively by the driving assembly, so that the distance between the two sets of roller sets 2 is relatively close, and the distance between the upper rollers 5 is increased by the adjusting assembly, so that the preheated metal wire can be conveniently passed through between the two sets of upper rollers 5 and lower rollers 6. Then, the two sets of roller sets 2 are driven to move away by the driving assembly, and the distance between the upper roller 5 and the lower roller 6 is reduced by the adjusting assembly, and finally the metal wire is pressed tightly. Finally, by connecting the two conductive joints 7 to the power supply, the current is conducted through the metal wire, and the metal wire generates heat under the action of its own resistance, so as to ensure its hot rolling effect.

[0026] A sliding groove 8 is opened on the surface of the base 1 along its length direction. Two connecting blocks 3 are slidably connected in the sliding groove 8. The driving assembly includes a lead screw 9 rotatably connected in the sliding groove 8. The surface of the lead screw 9 is provided with threads with opposite helix directions and is respectively threadedly connected to the two connecting blocks 3. One end of the base 1 is equipped with a motor 10 for driving the lead screw 9. By driving the lead screw 9 with the motor 10, the two sets of roller sets 2 are driven to approach, so as to conveniently pass the metal wire through between the two sets of upper rollers 5 and lower rollers 6.

[0027] The upper rolling wheel is rotatably connected between two connecting plates 4. The connecting plates 4 are provided with sliding grooves 11 in the vertical direction. A slider 12 is slidably connected in the sliding grooves 11. The lower rolling wheel is rotatably connected between two sliders 12. The adjusting assembly is used to adjust the height position of the slider 12. By driving the slider 12 to slide downward along the sliding groove 11 through the adjusting assembly, the lower rolling wheel 6 moves downward, so as to increase the distance between the lower rolling wheel 6 and the upper rolling wheel 5, so as to facilitate the metal wire to pass through between the upper rolling wheel 5 and the lower rolling wheel 6.

[0028] The conductive connectors 7 are arranged on one side of the slider 12. The slider 12 is made of conductive metal. By connecting two conductive connectors 7 to a power source, when the metal wire passes through between two groups of upper rolling wheels 5 and lower rolling wheels 6, and after the adjusting assembly drives the upper rolling wheel 5 to move upward and clamp the metal wire, the current enters the metal wire and conducts. During the process of winding and hot rolling the metal wire, its own temperature is guaranteed, so as to ensure the hot rolling effect.

[0029] The adjusting assembly includes two fixing plates 13 arranged on both sides of the middle of the surface of the base 1. Two abutting rods 14 are hinged on the fixing plates 13. The two ends of the abutting rods 14 facing the base 1 are inclined upward and abut against the bottom of the slider 12. The lower surface of the slider 12 is arranged in an arc shape. The adjusting assembly further includes an adjusting member for adjusting the angle of the abutting rods 14. By means of the adjusting member, the abutting rods 14 are inclined upward towards their movable ends. When the driving assembly drives two groups of rolling roller sets 2 to move relatively, the height positions of the two lower rolling wheels 6 gradually decrease, and the distance between them and the upper rolling wheel 5 increases, so as to facilitate the metal wire to pass through between the upper rolling wheel 5 and the lower rolling wheel 6. After the driving assembly drives two groups of rolling roller sets 2 to move away, under the action of the abutting rods 14, the height positions of the lower rolling wheels 6 gradually rise, and finally the metal wire is clamped and the current is conducted. The abutting rods 14 are made of insulating materials to ensure processing safety.

[0030] The adjusting member includes an adjusting rod 15 arranged on the surface of the base 1. The top of the adjusting rod 15 is arranged in an arc shape and abuts against the bottom of the abutting rod 14. Four grooves 16 corresponding to the four adjusting rods 15 are arranged on the surface of the base 1 along its length direction. A convex block 17 slidably connected in the groove 16 is arranged at the bottom of the adjusting rod 15. A screw rod 18 is rotatably connected in the groove 16. The screw rod 18 passes through and is threadedly connected to the convex block 17. One end of the screw rod 18 extends out of the side wall of the base 1 and is provided with a rotating handle 19.

[0031] By driving the screw rod 18 to rotate through the rotating handle 19, the adjusting rod 15 is driven to slide along the groove 16 to adjust the deflection angle of the abutting rod 14, so that the height positions of the two lower rolling wheels 6 can be adjusted separately, further improving the applicable range of the processing of this equipment.

[0032] The specific embodiments are only explanations of the present invention and are not limitations thereof. After reading this specification, those skilled in the art may make modifications to the embodiments that do not contribute creatively as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
