[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example
[0017] This embodiment 1 provides a wire drawing control system, including: a loading box 1, a transport component, a tank body 11, a wire drawing machine 14 and a control module; The transport assembly includes a conveying trough 4, a negative pressure generator 8 and a conveying pipe 10; the discharge port of the loading box 1 is connected to the conveying trough 4, and the conveying trough 4 is provided with a storage port 6 at one end away from the loading box 1; the negative pressure generator 8 passes below the storage port 6, and the negative pressure generator 8 is connected to the trough body 11 through the conveying pipe 10; A control module is used to obtain the operating status of the wire drawing machine 14; according to the operating status, based on a preset feeding frequency, the mixture in the loading box 1 is transported to the tank body 11 through a transport component to control the actual mixture concentration in the tank body 11 to be at a preset mixture concentration; the steel wire to be treated is pre-treated through the tank body 11 with a preset mixture concentration, and the pre-treated steel wire is then drawn through the wire drawing machine 14 to obtain the drawn steel wire.
[0018] The technical concept of the present invention is: through the cooperation of the loading box 1, the transport component, the tank body 11, the wire drawing machine 14 and the control module, the automatic addition control of the mixture is realized, so that the actual mixture concentration in the tank body 11 is always within the preset mixture concentration, ensuring the quality requirements of the product process control, greatly reducing the workload of employees, and ensuring the stability of production and the quality of the finished product.
[0019] like Figure 1 and Figure 2 As shown, a stirring motor 2 and a stirring rod 3 are provided in the feeding box 1, and the stirring motor 2 is connected to the stirring rod 3. The feeding box 1 in this embodiment contains a mixture of borax powder and a film-forming agent. When the stirring motor 2 is started, the stirring rod 3 below is driven to stir, and the stirring of the mixture by the stirring rod 3 makes the mixture flow evenly in the box, thereby increasing the fluidity of the powder.
[0020] The discharge port of the feeding box 1 is funnel-shaped, which is convenient for uniform discharge. A rectangular conveying trough 4 is made below the discharge port and assembled with the feeding box 1.
[0021] The conveying trough 4 is provided with a storage port 6 at one end away from the loading box 1; the storage port 6 is rectangular, and an adjusting block 7 with an adjusting screw 15 is also provided inside the storage port 6. The adjusting screw 15 drives the adjusting block 7 to move forward and backward to control the volume inside the storage port 6 and thus control the volume of the mixture inside the storage port 6. The volume of the storage port 6 is adjusted according to the amount of the mixture added to meet the amount of the mixture added.
[0022] A cylinder 5 is also provided on the end of the conveying trough 4 away from the storage port 6, which is used to push the conveying trough 4 back and forth to transport the mixture into the trough body 11. A top block device 8 is also provided on the cylinder 5, so as to push the mixture from top to bottom, and ensure the normal discharge of the mixture at the storage port 6 in a double insurance manner without forming a blockage phenomenon. The cylinder 5 in this embodiment is a double-rod double-axis cylinder, model SC50*1200.
[0023] A negative pressure generator 8 is installed below the material storage port 6 . The negative pressure generator 8 is connected to the tank body 11 through a delivery pipe 10 . The function of the negative pressure generator 8 is to suck the mixture into the tank body 11 by means of negative pressure.
[0024] The control module includes a PLC program controller 13 and an operation panel 12. The PLC program controller 13 automatically identifies the current operating status of the wire drawing machine 14, and the feeding frequency can be manually set on the operation panel 12. When one wire drawing machine 14 is running, the corresponding feeding frequency is set, and when two wire drawing machines 14 are running at the same time, the corresponding feeding frequency is set. The concentration of the mixture is controlled by different feeding frequencies. When the two machines stop at the same time, a delay time is set on the operation panel 12, and the mixture delivery is stopped after the time is reached to prevent excessive addition of borax powder when the machine tool stops for a long time. After the above settings are completed, they are automatically controlled by the PLC program controller 13, and there is no need for manual repeated settings. Example
[0025] This embodiment 2 provides a wire drawing control method based on the wire drawing control system of embodiment 1, such as Figure 3 As shown, the following steps are included: Obtaining the operating status of the wire drawing machine 14; According to the operation state, the mixture in the loading box 1 is transported to the tank body 11 through the transport component based on the preset feeding frequency, so as to control the actual mixture concentration in the tank body 11 to be at the preset mixture concentration; The steel wire to be treated is pretreated by passing through a tank 11 with a preset mixture concentration, and the pretreated steel wire is then drawn by a wire drawing machine 14 to obtain the drawn steel wire.
[0026] In this embodiment, the mixture in the loading box 1 includes borax powder and a film-forming agent, and the mixing ratio of the borax powder and the film-forming agent is 0.1-10: 1. Preferably, the mixing ratio of the borax powder and the film-forming agent is 1:1.
[0027] The preset mixture concentration includes the concentration of borax powder and the concentration of film-forming agent; the concentration of borax powder is 160-300 g / L; the concentration of film-forming agent is 160-300 g / L. Preferably, the concentration of borax powder is 190-270 g / L; the concentration of film-forming agent is 190-270 g / L.
[0028] Based on the standard concentration of 230±40 g / L, in the initial stage, the amount added per minute is simulated, small amounts are added multiple times, and samples are taken repeatedly to test the concentrations in different time periods to calculate the amount added per hour, that is, the feeding frequency. The purpose is to stabilize the concentration for 24 hours and reduce fluctuations. The addition is set to 24 hours a day according to the amount added.
[0029] Specifically, according to the operating state, based on the preset feeding frequency, the mixture in the loading box 1 is transported to the tank body 11 through the transport component, including: In response to the operation signal of the single wire drawing machine 14 in the operation state, the mixture in the loading box 1 is transported to the tank body 11 through the transport component at a feeding frequency of once every 250-290 seconds; In response to the operation signal of the two wire drawing machines 14 in operation state, the mixture in the loading box 1 is transported to the tank body 11 through the transport component at a feeding frequency of once every 190-230 seconds; In response to the stop signal of all the wire drawing machines 14 in the operating state, the mixture in the loading box 1 is stopped from being transported into the tank body 11 through the transport component based on the preset delay time.
[0030] During normal production, the feeding frequency of starting one wire drawing machine 14 and the feeding frequency of starting two wire drawing machines 14 are manually set in advance through the operation panel 12. The adding time of one wire drawing machine 14 is set to 270 seconds and the adding frequency is 1 time. The adding time of two wire drawing machines 14 is set to 210 seconds and the adding frequency is 1 time. When one or two wire drawing machines 14 are started, the PLC program controller 13 collects the running status of the wire drawing machines 14, identifies the specific number of wire drawing machines 14 started, and When a signal is given to the operation panel 12, the control adding device is started, and the mixture in the feeding box 1 is stirred regularly by the stirring rod 3 of the stirring motor. The stirred mixture flows into the conveying trough 4 and is conveyed to the storage port 6 by the cylinder 5. After the powder is conveyed to the storage port 6, it is sucked by the negative pressure generator 8 below and flows into the trough body 11 through the conveying pipe 10. During the conveying process, the top block device 8 performs a secondary push to ensure that the powder is discharged normally, and the regulating block 7 is used to adjust the capacity of the powder. The steel wire to be treated is pre-treated through the trough body 11 with a preset mixture concentration, and the pre-treated steel wire is drawn through the wire drawing machine 14 to obtain the drawn steel wire.
[0031] The use of the redesigned automatic addition wire drawing control system and wire drawing control method reduces the manual operation of employees, realizes automatic addition control, and the addition amount is unified, which not only ensures the quality requirements of product process control, but also greatly reduces the workload of employees and ensures the stability of production.
