Description

Technical Field

[0001] The invention relates to the field of wire drawing machines, in particular to a tensioning and adjusting mechanism for wire drawing machines. Background Art

[0002] Wire drawing machine is also called wire drawing machine. It belongs to the pre-processing equipment for the production of standard parts and other metal products. Its purpose is to draw the wire or rod produced by steel manufacturers and transported to the production enterprises of standard parts and other metal products through the wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wire or rod meet the raw material processing requirements for the production of standard parts and other metal products. Therefore, the pre-processing quality of wire or rod by wire drawing machine is directly related to the product quality of standard parts and other metal product manufacturers. Wire drawing machine belongs to the metal wire drawing machine in the metal product equipment industry. Wire drawing machine is widely used in the production and pre-processing of metal products such as steel wire, rope wire, prestressed steel wire, standard parts, etc. The tension adjustment device of the existing wire drawing machine has a simple structure and does not have a lubrication component. During the adjustment operation, the friction force is likely to cause the wire to wear, affecting production. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a wire drawing tension adjustment mechanism, which has the advantages of solving the problems raised in the above background technology.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A tensioning adjustment mechanism for a wire drawing machine comprises a workbench, the top surface of the workbench is vertically fixedly connected to a support plate, the outer wall of the support plate is rotatably matched with a plurality of groups of rollers, wires are coiled between the plurality of groups of rollers, and an adjustment mechanism is arranged between the plurality of groups of rollers on the outer wall of the support plate, the adjustment mechanism comprises an adjustment slot provided on the outer wall of the support plate, an adjustment block is slidably matched in the adjustment slot up and down, a driving component for driving the adjustment block to move up and down is also arranged in the adjustment slot, a hollow bracket is fixedly connected to the outer wall of the adjustment block, a rotating shaft is rotatably connected in the hollow bracket, and an adjustment wheel is fixedly connected on the outer side of the rotating shaft in the hollow bracket, An annular groove is provided on the outer wall of the adjusting wheel, the silk thread passes through the annular groove and is coiled with other multiple groups of rollers, a lubrication assembly is provided above the adjusting wheel and at the top of the hollow bracket, the lubrication assembly includes an oil nozzle fixedly connected to the top of the hollow bracket, the bottom of the oil nozzle is vertically arranged toward the adjusting wheel, the top of the oil nozzle is connected to an oil inlet pipe, a control valve is provided on the outside of the oil inlet pipe, one end of the oil inlet pipe extends to the outside of the hollow bracket, the extended end of the oil inlet pipe is connected to a lubricating oil tank, and the lubricating oil tank is fixedly connected to the top of the support plate.

[0005] By adopting the above technical solution, during operation, the operator passes the silk thread through the annular groove on the adjusting wheel and winds it around the outside of multiple groups of rollers. As the silk thread is stretched, the tension of the silk thread gradually increases. To ensure that the tension of the silk thread is controlled within a range during stretching, the operator turns on the drive assembly to drive the adjusting block and the hollow bracket on the adjusting block to move up and down to a suitable height. At this time, the silk thread in the annular groove on the adjusting wheel moves up and down to a suitable height, thereby adjusting the tension of the silk thread during stretching. After the tension of the silk thread is adjusted, the silk thread will contact the annular groove to generate friction. At this time, the operator turns on the control valve on the oil inlet pipe, and the lubricating oil in the lubricating oil tank is dripped to the oil nozzle through the oil inlet pipe, and drips into the annular groove through the oil nozzle, which plays a lubricating role and reduces the wear of the silk thread.

[0006] Further configuration: the driving assembly includes an adjusting cylinder arranged at the top of the adjusting slot, a connecting plate is fixedly connected to the bottom of the adjusting cylinder output end, and the connecting plate is fixedly connected to the top of the adjusting block at one side away from the adjusting cylinder.

[0007] By adopting the above technical solution, during the adjustment operation, the operator turns on the adjustment cylinder according to the operation requirements, and cooperates with the connecting plate to drive the adjustment block and the hollow bracket on the adjustment block to move up and down to a suitable height. At this time, the silk thread in the annular groove on the adjusting wheel moves up and down to a suitable height, thereby adjusting the tension of the silk thread when it is stretched.

[0008] Further configuration: a material receiving box with an opening upward is provided on the outer wall of the support plate below the hollow bracket, a filter screen is fixedly connected to the top of the material receiving box, an oil outlet is opened through one side of the material receiving box, an oil outlet is connected to the oil outlet, and a switch valve is provided on the outside of the oil outlet pipe.

[0009] By adopting the above technical solution, during lubrication operation, the lubricating oil in the annular groove will drip directly into the receiving box. When the lubricating oil drips, the filter net set on the top of the receiving box can filter out larger impurities to avoid affecting the secondary use of the lubricating oil.

[0010] It is further configured that an annular metal ring is matched and fixedly connected in the annular groove.

[0011] By adopting the above technical solution, the annular metal ring is arranged to contact the silk thread, thereby reducing friction and avoiding wear of the silk thread.

[0012] It is further provided that the outer side of the annular metal ring is coated with an anti-rust coating.

[0013] By adopting the above technical solution, the setting of the anti-rust coating plays an anti-rust protection role, avoiding the wear and rust of the annular metal caused by long-term contact between the wire and the annular metal, thereby preventing the operation from being affected.

[0014] In summary, the present invention has the following beneficial effects: When the present invention is in operation, the operator passes the silk thread through the annular groove on the adjusting wheel and winds it around the outside of multiple groups of rollers. As the silk thread is stretched, the pulling force of the silk thread gradually increases. To ensure that the tension of the silk thread during stretching is controlled within a range, the operator turns on the driving assembly to drive the adjusting block and the hollow bracket on the adjusting block to move up and down to a suitable height. At this time, the silk thread in the annular groove on the adjusting wheel moves up and down at a suitable height, thereby adjusting the tension of the silk thread during stretching. After the tension of the silk thread is adjusted, the silk thread will contact the annular groove to generate friction. At this time, the operator turns on the control valve on the oil inlet pipe, and the lubricating oil in the lubricating oil tank is dripped to the oil nozzle through the oil inlet pipe, and drips into the annular groove through the oil nozzle, thereby playing a lubricating role and reducing the wear of the silk thread.
