Description

Technical Field

[0001] This application belongs to the technical field of tungsten wire drawing equipment, and specifically relates to a tungsten wire drawing mechanism. Background Technology

[0002] A tungsten wire drawing and forming device is a piece of equipment used in the production of aluminum wires. It features adjustable roller resistance, increased tensile force while maintaining drawing speed, reduced equipment length and footprint, and applicability to various specifications of tungsten wire. In modern industrial manufacturing, the tungsten wire drawing and forming device is one of the important production equipment, mainly used to stretch and deform larger diameter tungsten wires into finer tungsten wires to meet various application requirements.

[0003] In the prior art, an aluminum wire drawing and forming device disclosed in CN118751705A includes a mounting frame and an aluminum wire. A transmission mechanism and a take-up mechanism are located at the rear of the mounting frame, while a feeding mechanism, a mounting box, a preheating module, a drawing seat, a guiding mechanism, and a take-up roller are located at the front of the mounting frame. The preheating module is fixedly mounted on the inner wall of the mounting box near the feeding mechanism, and the drawing seat is fixedly mounted on the outer wall of the mounting box near the guiding mechanism. The take-up mechanism is drivenly connected to the take-up roller. The output end of the guiding mechanism is drivenly connected to a first feed roller, a second feed roller, and a drive shaft. The aluminum wire sequentially passes through the feeding mechanism, mounting box, preheating module, drawing seat, guiding mechanism, and take-up roller. This drawing mechanism can only draw a single tungsten wire, resulting in low drawing efficiency.

[0004] In a smart anti-breakage copper busbar drawing machine with publication number CN117584009A, the drawing structure is equipped with a first small drawing component. The first small drawing component detects the optimal matching drawing height with the copper busbar, so that the drawing strength of the small drawing roller and the large drawing roller on the copper busbar is within a reasonable range, but it cannot draw tungsten wire. Utility Model Content

[0005] The purpose of this utility model is to address existing problems by improving upon the existing technology of an intelligent anti-breakage copper busbar drawing machine, and providing a tungsten wire drawing mechanism that incorporates multiple tungsten wires in a belt conveyor structure for wire drawing.

[0006] To achieve the aforementioned technical objectives, the following technical solution is provided: a tungsten filament drawing mechanism, comprising a transport assembly fixed on a support, and a drawing mechanism fixed on the support and located above the transport assembly.

[0007] The feature is that the transport component includes a belt conveyor structure and multiple sets of wire drawing rollers arranged in the conveying direction and located above the belt conveyor structure, wherein each set of wire drawing rollers has at least two wire drawing rollers, and the distance between the wire drawing rollers and the belt conveyor structure gradually decreases from large to small in the conveying direction;

[0008] The wire drawing mechanism includes at least two sets of pressure wire drawing mechanisms. Each set of pressure wire drawing mechanisms includes a pressure roller. The distance between the pressure roller and the belt conveyor structure gradually decreases from large to small in the conveying direction, and the lower end is located in the bottom surface formed with the wire drawing roller set.

[0009] In one feasible embodiment, the pressure drawing mechanism also includes a mounting platform fixed to a bracket, on which a calibration mechanism for calibrating the pressure drawing mechanism is mounted.

[0010] In one feasible embodiment, the pressure drawing mechanism includes a pair of slide blocks fixed to a mounting platform; wherein a fixed side plate is slidably mounted on each pair of slide blocks, and a pressure motor is fixedly mounted on the fixed side plate, the pressure motor being connected to a pressure roller via a belt.

[0011] In one feasible embodiment, the slide block assembly contains two slide blocks, wherein the fixed side plate is provided with two rows of fixed groups with several sliders, and each fixed group is fitted onto the slide block.

[0012] In one feasible embodiment, the pressure drawing mechanism also includes a pair of adjusting screws, which are fixed to the mounting platform by bearings and located between the slide columns of the slide column assembly. Each adjusting screw is provided with a threaded sleeve, which is fixed to the fixed side plate. A worm gear motor located above the calibration mechanism is provided at the upper end of the adjusting screw.

[0013] In one feasible embodiment, the calibration mechanism includes a base fixed to a mounting platform, the base having a channel with openings at both ends aligned with a pair of adjusting screws.

[0014] A telescopic cylinder is installed inside the channel. The end rod of the telescopic cylinder is connected to a support rod, and its bottom is also connected to a support rod. The support rod is fixedly connected to an adjustment frame located between the adjustment screw and the openings at both ends of the channel.

[0015] The openings at both ends of the channel are equipped with outward-opening claws that pass through the adjustment frame and have threads on the inside to clamp the adjustment screw.

[0016] When the telescopic cylinder extends, the adjusting frame moves outward to tighten the opened clasps.

[0017] In one feasible implementation, a displacement sensor system is installed on the bottom surface of the chuck and the upper surface of the mounting platform. When a change in distance is detected, the telescopic cylinder and the worm gear motor are adjusted.

[0018] In one feasible embodiment, the belt conveyor structure includes a conveyor support frame. Reinforcing plates are provided on both side walls of the conveyor support frame. The reinforcing plates are L-shaped and have bolt grooves and slide rails arranged side by side. The reinforcing plates are fixed to the conveyor support frame by inserting bolts into the bolt grooves. A spring rod is slidably connected to the slide rail. The spring rod passes through the upper end bend of the reinforcing plate and a support rod is fixedly installed on its top. The support rod is fixedly connected to an active wire drawing roller.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] Multiple tungsten wires are drawn onto the surface of the belt conveyor structure using pressure rollers. These pressure rollers rotate faster than both the belt conveyor and the drawing roller assembly, and their rotation direction is the same as the conveying direction. This rapid grinding of the tungsten wires by the pressure rollers accelerates the reduction of their diameter. Furthermore, a calibration mechanism is installed on the pressure drawing mechanism. This mechanism allows for timely calibration when the pressure rollers vibrate during rotation, causing a positional shift in the entire mechanism, or when the entire mechanism descends under gravity, preventing the production of defective products.

[0030] like Figures 1 to 5 The embodiment shown includes a tungsten filament drawing mechanism, comprising a transport assembly 1 fixed on a support, and a drawing mechanism 2 fixed on the support and located above the transport assembly 1. The transport assembly 1 includes a belt conveyor structure 3 and four sets of drawing roller groups 13 arranged in the conveying direction and located above the belt conveyor structure 3. Each set of drawing roller groups 13 has two drawing roller cylinders 31. The distance between the drawing roller cylinders 31 and the belt conveyor structure 3 gradually decreases from large to small in the conveying direction.

[0031] The belt conveyor structure 3 includes a conveyor support 37. Reinforcing plates 32 are provided on both side walls of the conveyor support 37. The reinforcing plates 32 are L-shaped and have bolt grooves 33 and slide rails 34. The bolt grooves 33 and slide rails 34 are arranged side by side. The reinforcing plates 32 are fixed to the conveyor support 37 by inserting bolts into the bolt grooves 33. A spring rod 35 is slidably connected to the slide rail 34. The spring rod 35 passes through the upper end bend of the reinforcing plate 32 and a support rod 36 is fixedly installed on its top. The support rod 36 is fixedly connected to an active wire drawing roller 31.

[0032] In this embodiment, the wire drawing mechanism 2 includes two sets of pressure wire drawing mechanisms 4. Each set of pressure wire drawing mechanisms 4 includes a pressure roller 41. The distance between the pressure roller 41 and the belt conveyor structure 3 gradually decreases from large to small in the conveying direction, and the lower end is located in the bottom surface formed with the wire drawing roller group 13.

[0033] In this embodiment, the distance between the drawing roller 31 and the pressure roller 41 and the belt conveyor structure 3 is determined by the actual situation of the tungsten wire. The distance at the inlet of the belt conveyor structure 3 is the diameter of the tungsten wire precursor, and the distance at the outlet of the belt conveyor structure 3 is the diameter of the tungsten wire required after actual processing.

[0034] In this embodiment, the specific pressure drawing mechanism 4 further includes a mounting platform 42, which is fixed on a bracket and has a calibration mechanism 5 for calibrating the pressure drawing mechanism 4. The pressure drawing mechanism 4 includes a pair of sliding column groups 43, which are fixed on the mounting platform 42. Each pair of sliding column groups 43 has a fixed side plate 44 slidably mounted on it, and a pressure motor 45 is fixedly mounted on the fixed side plate 44. The pressure motor 45 is connected to a pressure roller 41 via a belt. Each sliding column group 43 contains two sliding columns. The fixed side plate 44 has two rows of fixed groups with several sliders 46, each fixed group being fitted onto a sliding column. The pressure drawing mechanism 4 also includes a pair of adjusting screws 47, which are fixed on the mounting platform 42 by bearings and located between the sliding columns of the sliding column group 43. Each adjusting screw 47 has a threaded sleeve fixed to the fixed side plate 44. A worm gear motor 48 is located above the calibration mechanism 5 at the upper end of the adjusting screw 47.

[0035] In this embodiment, the calibration mechanism 5 includes a base 51 fixed to the mounting platform 41. The base 51 has a channel, and the openings at both ends of the channel are aligned with a pair of adjusting screws 47. A telescopic cylinder 52 is installed in the channel. The end rod of the telescopic cylinder 52 is connected to a support rod 53, and the bottom of the cylinder is also connected to a support rod 53. The support rod 53 is fixedly connected to an adjusting frame 54 located between the adjusting screws 47 and the openings at both ends of the channel. Outwardly opening claws 55 are provided on the outer side of the openings at both ends of the channel. The claws 55 pass through the adjusting frame 54 and have threads on their inner side to clamp the adjusting screws 47. When the telescopic cylinder 52 extends, the adjusting frame 54 moves outward to tighten the open claws 55.

[0036] Furthermore, a displacement sensor system is installed on the bottom surface of the chuck 55 and the upper surface of the mounting platform 41. When a change in distance is detected, the telescopic cylinder 52 and the worm gear motor 48 are adjusted.

[0037] In this embodiment, after adjusting the height of the drawing roller 31, the height of the pressure roller 41 is adjusted. The height of the pressure roller 41 is adjusted by a worm gear motor 48 controlled by a circuit. Then, the telescopic cylinder 52 is adjusted to tighten the adjusting screw 47 with the chuck 55. When the displacement sensor system detects a change in the distance between the bottom surface of the chuck 55 and the upper surface of the mounting platform 41, the telescopic cylinder 52 adjusts the chuck 55 to loosen while the worm gear motor 48 operates, ensuring that the pressure roller 41 does not suddenly drop. During the drawing process, the rotational speed of the drawing roller 31 is consistent with the rotational speed of the belt conveyor structure 3, allowing multiple tungsten wires to be transmitted stably. The downward pressure and high-speed rotation of the pressure roller 41 allows the tungsten wires to be rapidly thinned. The rotational speed of the pressure roller 41 is 5 to 10 times that of the drawing roller 31.
