Description

Technical Field

[0001] This utility model relates to the field of iron wire production technology, and more specifically, to an iron wire coarse drawing device. Background Technology

[0002] Iron wire is a basic metal product characterized by high strength, low cost, and ease of processing. It is widely used in various fields such as industry, agriculture, construction, and daily life. For example, it can be used for rebar tying and securing, as well as as the core material for steel wire ropes or to make chains and screens. In iron wire production, rough drawing is a crucial step. It is mainly used to draw thicker raw materials through multiple passes to initially reduce the diameter and form semi-finished wire, laying the foundation for subsequent fine drawing and surface treatment. An annealing process may be added during rough drawing, which is necessary for wires that have hardened significantly after multiple drawing processes. For medium- and low-strength wires, rough drawing is generally carried out using pulley-type wire drawing machines. However, with pulley-type wire drawing machines, annealing is delayed, and it is difficult to heat the wire during rough drawing. Furthermore, annealing is not essential for the rough drawing process. Therefore, it is necessary to improve the existing rough drawing equipment. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wire drawing device, which sets up a heating device on the existing pulley-type wire drawing machine, effectively solving the problem that the existing pulley-type wire drawing machine is difficult to handle in terms of wire drawing hardening.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A wire drawing device includes a pulley-type wire drawing machine, heating components, and a control device. Multiple heating components are mounted on the pulley-type wire drawing machine. One heating component is positioned between two adjacent pulley groups on the pulley-type wire drawing machine. Each heating component includes a heating column and a heat-conducting wheel. The heating column is vertically positioned, and the heat-conducting wheel is sleeved on the heating column and rotatably connected to it. Wires positioned between two pulley groups are wound around the heat-conducting wheel at least once. The heating columns of all the multiple heating components are connected to the control device.

[0006] In one embodiment, the wire between the two pulley sets is wound around the heat-conducting wheel at least five times.

[0007] In one embodiment, the temperature of the heating column at the front is higher than the temperature of the heating column at the rear.

[0008] In one embodiment, the heating temperature of the heating column is ≤500°C.

[0009] In one embodiment, the heating temperature of the front heating column is 20-30°C higher than that of the rear heating column in two adjacent heating columns.

[0010] In one embodiment, the wire coarse drawing device further includes a temperature sensor, with each heating component corresponding to one temperature sensor. The temperature sensor is located on one side of the heat-conducting wheel and is used to detect the temperature of the heat-conducting wheel. All of the temperature sensors are connected to the control device.

[0011] In one embodiment, the heating assembly further includes a protective cover fitted over the heat-conducting wheel, and the protective cover has an opening for the wire to pass through.

[0012] In one embodiment, a warning light is provided on the protective cover, and the warning light is connected to the control device.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0020] like Figure 1As shown, this utility model proposes a wire drawing device, including a pulley-type wire drawing machine 1, a heating assembly, and a control device. Multiple heating assemblies are arranged on the pulley-type wire drawing machine 1. A heating assembly is arranged between two adjacent pulley groups 4 on the pulley-type wire drawing machine 1. The heating assembly includes a heating column 2 and a heat-conducting wheel 3. The heating column 2 is arranged vertically, and the heat-conducting wheel 3 is sleeved on the heating column 2. The heat-conducting wheel 3 and the heating column 2 are rotatably connected. The wire between the two pulley groups 4 is wound around the heat-conducting wheel 3 at least once. The heating columns 2 of the multiple heating assemblies are all connected to the control device.

[0021] Each pulley group 4 of the pulley-type wire drawing machine 1 corresponds to one drawing pass, with the wire winding around the pulleys in an "S" shape or spiral path. This invention adds a heating device to the existing pulley-type wire drawing machine 1, heating the wire between two drawing passes via a heat-conducting wheel 3, making the wire easier to draw and reducing the likelihood of wire hardening. Throughout the entire drawing process, the wire remains heated. After each drawing pass, the wire cools and is reheated to preheat for the next drawing pass. Preferably, the wire between the two pulley groups 4 winds around the heat-conducting wheel 3 at least five times, allowing sufficient time for heating.

[0022] In this invention, the control device controls whether the heating columns 2 enter the heating state. It is easy to understand that when heating is not required, the control device controls all heating columns 2 to turn off, or the control device controls several heating columns 2 to enter the heating state. The control device is a conventional controller, such as a PLC controller.

[0023] The connection between the heat-conducting wheel 3 and the heating column 2 is similar to that of a conventional guide wheel. The heat-conducting wheel 3 serves both to transfer the iron wire and to transfer heat, using the heat from the heating column 2 to heat the iron wire.

[0024] In some embodiments, the temperature of the heating column 2 at the front is higher than the temperature of the heating column 2 at the rear. It is easy to understand that the diameter of the wire gradually decreases during the coarse drawing process. The wire in contact with the heating column 2 at the front has a larger diameter and requires a higher heating temperature, while the wire in contact with the heating column 2 at the rear has a smaller diameter and can be heated at a relatively lower temperature. Generally, the heating temperature of the heating column 2 is ≤500℃, and more preferably, the heating temperature is ≤400℃.

[0025] Preferably, in two adjacent heating columns 2, the heating temperature of the front heating column 2 is 20-30°C higher than that of the rear heating column 2.

[0026] In some embodiments, the wire drawing device further includes a temperature sensor 6, with one temperature sensor 6 corresponding to each heating component. The temperature sensor 6 is located on one side of the heat-conducting wheel 3 and is used to detect the temperature of the heat-conducting wheel 3. Multiple temperature sensors 6 are connected to a control device. The heating of the wire is controlled by intelligently regulating the opening and closing of the heating column 2 through the temperature sensors 6 and the control device.

[0027] In some embodiments, the heating assembly further includes a protective cover 5, which is fitted over the heat-conducting wheel 3 and has an opening for the wire to pass through. The protective cover 5 is used to prevent workers from accidentally touching it.

[0028] Preferably, a warning light 7 is installed on the protective cover 5, and the warning light 7 is connected to the control device. When the corresponding heating column 2 inside the protective cover 5 is activated, the warning light 7 illuminates to remind the staff.

[0029] In some embodiments, the wire drawing device further includes an air cooler, which is located behind the pulley-type wire drawing machine 1 and connected to the control device. After the drawing is completed, the wire is cooled by air cooling. It is easy to understand that as long as any heating component is started, the subsequent air cooler will also be started accordingly, and when all heating components are turned off, the air cooler will also remain off.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
