Tension regulating device for metal wire drawing machines

Abstract

This utility model belongs to the field of metal wire drawing technology, and in particular, it is a tension adjustment device for a metal wire drawing machine. The proposed solution includes a mounting frame and an adjustment mechanism mounted on the mounting frame. The adjustment mechanism includes a turntable, a geared disc, an electric cylinder, a connecting plate, a rack, a fixed disc and a fixed base, an elastic component, a connecting arm, and wire wheels. When the copper wire is slightly loose during transport, the elastic component can adjust the position of the wire wheels in real time, thereby adjusting the tension of the copper wire. If the tension sensor detects that the copper wire is too loose, the electric cylinder responds promptly, pushing the rack along the groove via the connecting plate. At this time, the geared disc meshing with the rack rotates, which drives the turntable to rotate synchronously, thus adjusting the vertical height of the two wire wheels. This allows for timely response to slight looseness or significant slack in the metal wire, adjusting the tension of the transported metal wire.

Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing technology, and in particular to a tension adjustment device for a metal wire drawing machine. Background Technology

[0002] Wire drawing machines, also known as wire extrusion machines, are widely used mechanical equipment in industrial applications, including machinery manufacturing, hardware processing, petrochemicals, plastics, bamboo and wood products, and wire and cable industries. Wire drawing machines can be categorized by their application, such as metal wire drawing machines, plastic wire drawing machines, and bamboo and wood wire drawing machines.

[0003] During the wire drawing process, the drawing die will gradually be damaged, and the elongation of the wire will change accordingly. If the drawing speed remains constant, the tension of the wire will increase until it breaks. When the wire drawing machine is running, different metal wires require different tensions. The wire drawing machine needs to adjust the tension to ensure smooth wire drawing during the process, and to prevent the tension from being too low or too high, which could lead to wire detachment and breakage, thus affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tension adjustment device for metal wire drawing machines, thereby solving the problems mentioned in the background section.

[0005] A tension adjusting device for a metal wire drawing machine includes a mounting frame and an adjusting mechanism mounted on the mounting frame. The adjusting mechanism includes a turntable, a geared disc, an electric cylinder, a connecting plate, a rack, a second fixed disc mounting base, an elastic component, a connecting arm, and a wire wheel. The geared disc is fixedly connected to the turntable via a connecting shaft. The rack slides along a groove in the mounting frame and is fixedly connected to the electric cylinder via the connecting plate. The fixed disc is fixed in the middle of the turntable. The second fixed base consists of two parts mounted opposite each other on the turntable. The connecting arm passes through the second fixed base and is elastically connected to the fixed disc via the elastic component. The wire wheel is fixed to the connecting arm.

[0006] By adopting the above technical solution, it is possible to adjust the tension of the conveyed metal wire.

[0007] A fixing seat is also installed on one side of the mounting frame, which is located on both sides of the turntable. A guide wheel is installed on the fixing seat, and a tension sensor is also installed on one side of the mounting frame.

[0008] By adopting the above technical solution, the metal wire is guided and arranged on the device, and the tension of the metal wire can be detected in real time.

[0009] The elastic component includes a telescopic rod and a spring. The two ends of the telescopic rod and the two ends of the spring are fixedly connected to the fixed plate and the connecting arm, respectively, and the spring is sleeved on the outside of the telescopic rod.

[0010] By adopting the above technical solution, the metal wire can be adjusted in real time.

[0011] The center points of the two guide wheels and the two spools are set on the same vertical section, and the center points of the two guide wheels and the center point of the fixed plate are on the same cross section.

[0012] By adopting the above technical solution, it is convenient to pull and arrange the metal wire.

[0013] The second fixing base is hollow, and the connecting arm has protruding ear plates on both sides. The outer wall contour of the connecting arm is adapted to the inner wall contour of the second fixing base, and the connecting arm can slide in the second fixing base.

[0014] By adopting the above technical solution, the connecting arm can be moved stably when adjusting the metal wire.

[0015] The beneficial effects of this utility model for a tension adjustment device used in a metal wire drawing machine are: When the copper wire becomes slightly loose during the conveying process, because one end of the connecting arm is elastically connected to the elastic component and the connecting arm is slidably connected to the fixed base, the position of the wire wheel can be adjusted in real time by relying on the elasticity of the elastic component, thereby adjusting the tension of the copper wire during conveying. If the tension sensor detects that the copper wire is too loose, the electric cylinder responds in time and pushes the rack along the slide groove through the connecting plate. At this time, the toothed disc meshing with the rack rotates. When the toothed disc rotates, it can drive the turntable to rotate synchronously, thereby adjusting the vertical height of the two wire wheels, so as to respond in time when the metal wire is slightly loose or has a large slack, and adjust the tension of the conveyed metal wire.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] This invention provides a tension adjustment device, such as a tension adjustment device for a metal wire drawing machine.

[0020] Includes mounting bracket 1 and adjustment mechanism mounted on mounting bracket 1; Reference Figure 1 and Figure 2 The adjustment mechanism is described in detail below. The adjustment mechanism includes a turntable 5, a gear plate 6, an electric cylinder 7, a connecting plate 8, a rack 9, a fixed plate 10, a second fixed seat 11, an elastic component 12, a connecting arm 13, and a spool 14. The gear plate 6 is fixedly connected to the turntable 5 through a connecting shaft. The rack 9 slides along the slide groove 101 of the mounting frame 1 and is fixedly connected to the electric cylinder 7 through the connecting plate 8. The fixed plate 10 is fixed in the middle of the turntable 5. The second fixed seat 11 consists of two fixed plates 10 mounted opposite each other on the turntable 5. The connecting arm 13 passes through the second fixed seat 11 and is elastically connected to the fixed plate 10 through the elastic component 12. The spool 14 is fixed on the connecting arm 13. The device is installed in a predetermined production area. It can be used to pull metal wires, including but not limited to copper wires and aluminum alloy wires. Taking copper wire as an example, the copper wire is pulled from the previous process of the production line to the top of the tension sensor 4, then around the top of the tension sensor 4, then around the bottom of an adjacent guide wheel 3, pulled to the top of an adjacent reel 14, then around the bottom of another reel 14, and finally around the top of a guide wheel 3 located on the other side of the mounting frame 1, and pulled to the next process of the production line, thus completing the placement of the copper wire on the tension adjustment device. The second fixed base 11 is hollow, and the connecting arm 13 has protruding ear plates on both sides. The outer contour of the connecting arm 13 is adapted to the inner contour of the second fixed base 11. The connecting arm 13 can slide in the second fixed base 11. When the copper wire is slightly loose during the conveying process, because one end of the connecting arm 13 is elastically connected to the elastic component 12, the connecting arm 13 is slidably connected to the second fixed base 11. Therefore, the position of the wire wheel 14 can be adjusted in real time by relying on the elasticity of the elastic component 12, thereby adjusting the tension of the copper wire during conveying. The electric cylinder 7 is controlled by a PLC (Programmable Logic Controller). Based on the detection signal transmitted by the tension sensor 4, the electric cylinder 7 is controlled to adjust the tension of the copper wire. If the tension sensor 4 detects that the copper wire is too loose, the electric cylinder 7 responds in time and pushes the rack 9 to move along the slide groove 101 through the connecting plate 8. At this time, the gear plate 6 meshing with the rack 9 rotates. When the gear plate 6 rotates, it can drive the turntable 5 to rotate synchronously, thereby adjusting the vertical height of the two wire wheels 14 to achieve the tension adjustment of the copper wire.

[0021] Reference Figure 1 On one side of the mounting frame 1, a fixed seat 2 is installed on both sides of the turntable 5. A guide wheel 3 is installed on the fixed seat 2. A tension sensor 4 is also installed on one side of the mounting frame 1. The center points of the two guide wheels 3 and the two wire wheels 14 are set on the same vertical section. The center points of the two guide wheels 3 and the center point of the fixed plate 10 are on the same cross section. When the copper wire passes through the device, the fixed seat 2 is set between the guide wheel 3 and the mounting frame 1. The fixed seat 2 supports the guide wheel 3, so that there is a certain distance between the guide wheel 3 and the side of the upper end plate of the mounting frame 1. This distance is greater than the distance from the fixed seat 2 11 to the side of the upper end plate of the mounting frame 1. This ensures that the copper wire is not affected by the fixed plate 10 and the fixed seat 2 11 during the traction process.

[0022] Reference Figure 1 To enable timely fine-tuning of the copper wire when it becomes slightly loose, the connecting arm 13 and the reel 14 are used. The elastic component 12 includes a telescopic rod and a spring. The two ends of the telescopic rod and the two ends of the spring are fixedly connected to the fixed plate 10 and the connecting arm 13, respectively. The spring is sleeved on the outside of the telescopic rod. By setting the telescopic rod, it is ensured that the connecting arm 13 can only move towards the fixed plate 10 or away from the fixed plate 10. With the elasticity of the elastic component 12, when the copper wire is slightly loose, the elastic force of the elastic component 12 can be used to push the connecting arm 13 to tighten the copper wire. At the same time, it can also play a buffering role when the drive turntable 5 adjusts the tension of the copper wire.

[0023] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
