Abstract

This invention discloses an applicable improved oil tank device and temperature control system for micro-drawing machines, relating to the field of micro-drawing machine technology. The invention addresses the oil tank used in micro-drawing machines to maintain stable drawing oil temperature. Firstly, the overall oil tank structure is improved: the lowest layer is designated as a water bath, and the uppermost layer as an oil tank. A cross-shaped insulation layer divides the oil tank into four areas: a return oil tank, a heating tank, an oil exchange tank, and an oil storage tank. U-shaped pipes and solenoid valves are used to connect or close these four areas. Based on this, temperature data from the return oil tank, heating tank, and oil exchange tank are used to generate control signals, which are then coordinated with the drawing oil temperature in the micro-drawing machine. The aim is to ensure that the drawing oil temperature is balanced with the peak output temperature. This is achieved by using a water bath heating method and restricting the flow of the drawing oil to achieve temperature balance.

Description

Technical Field

[0001] This invention relates to the field of micro-extrusion machine technology, specifically to a suitable micro-extrusion machine oil sump improvement device and temperature control system. Background Technology

[0002] The manufacturing process of enameled wire consists of a series of different production steps. Among them, the wire drawing process is a very important step in the entire manufacturing process and is also the step before the enameling. The function of the wire drawing process is to draw the standard wire into the corresponding enameled wire size. According to the size and the corresponding wire drawing machine model, the wire drawing equipment is generally divided into large drawing machine, medium drawing machine, small drawing machine and micro drawing machine. This invention mainly relates to micro drawing machine equipment, so it will be described in detail here.

[0003] Micro-drawing machines are mainly used for drawing aluminum wires with dimensions below 0.1800mm. The wire drawing process involves drawing large-diameter raw materials into smaller wires through drawing dies, which is a cold drawing process. Therefore, drawing oil is required during production. Drawing oil is the most important raw material in wire drawing production, playing roles such as lubrication, cleaning, cooling, and anti-oxidation during the drawing process, providing quality assurance for the semi-finished products after drawing. The temperature and viscosity of the drawing oil directly affect the stability of the continuous drawing process. In large, medium, and small drawing machines, the heat generated during production is sufficient to maintain the temperature of the drawing oil. However, in the actual production process of micro-drawing machines, the heat generated during drawing is much lower than that of large, medium, and small drawing machines. Therefore, the actual temperature of the drawing oil is lower and unstable, and it is also greatly affected by the temperature difference of the external environment. This leads to unstable viscosity of the drawing oil during continuous production, making it easy for the wire to break during drawing, which seriously affects production efficiency and product quality.

[0004] Therefore, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to provide a suitable micro-drawing machine oil pool improvement device and temperature control system, which solves the problems of unstable drawing oil temperature and unstable drawing oil viscosity, thereby improving production efficiency and product quality.

[0006] The objective of this invention can be achieved through the following technical solution: A suitable micro-extrusion machine oil tank improvement device, comprising an oil tank body, wherein a horizontally arranged partition is installed inside the oil tank body, and an oil chamber and a water bath chamber are arranged inside the oil tank body from top to bottom through the partition. A water bath tank is installed in the water bath chamber. A vertically arranged cross-shaped heat insulation layer is installed at the center point of the upper surface of the partition. The cross-shaped heat insulation layer is connected to the inner wall of the oil tank body. The oil chamber is provided with an oil return chamber, a heating chamber, an oil exchange chamber, and an oil storage chamber through the cross-shaped heat insulation layer. The oil return chamber, heating chamber, oil exchange chamber, and oil storage chamber are arranged counterclockwise along the center point of the partition.

[0007] Four U-shaped tubes are installed on the cross-shaped insulation layer. The four U-shaped tubes are inverted and arranged in a circular array along the center point of the cross-shaped insulation layer. The return oil chamber and the heating chamber, the heating chamber and the oil exchange chamber, the oil storage chamber and the oil exchange chamber, and the oil storage chamber and the return oil chamber are connected by the U-shaped tubes. The oil tank body is equipped with a temperature detection component, a flow direction control component and a controller. The temperature detection component consists of three temperature sensors. The three temperature sensors are located on the outside of the oil tank body corresponding to the return oil chamber, the heating chamber and the oil exchange chamber, respectively, and the probes of the temperature sensors are located inside the return oil chamber, the heating chamber and the oil exchange chamber.

[0008] The flow control component consists of four solenoid valves. The solenoid valves are installed at the upper end of the U-shaped tube. The U-shaped tube is connected to the input and output ends of the solenoid valves. The solenoid valves are located inside the cross-shaped insulation layer. The water bath is located directly below the heating chamber. The oil tank body is equipped with a return oil suction pump and an oil suction pump at the positions corresponding to the return oil chamber and the storage oil chamber, respectively.

[0009] A temperature control system for a suitable micro-extrusion oil sump improvement device is disclosed. The temperature control system uses a controller as its operating platform and includes a data collection unit, a data analysis unit, and a flow control unit. The data collection unit collects dynamic and static data and sends them to the data analysis unit. The data analysis unit uses the dynamic and static data to establish a formula for calculating the temperature rise and sets a peak oil outlet temperature. It then combines the calculated data from the temperature rise formula with the peak oil outlet temperature to generate a control signal. The flow control unit uses the control signal from the data analysis unit as a basis to perform flow control actions on the return oil suction pump, the oil suction pump, and the solenoid valve.

[0010] The system is further configured such that: the dynamic data includes the real-time temperature values ​​displayed on three temperature sensors and the heating temperature of the water bath; the static data includes the constant volume values ​​of the return oil tank, the heating tank, the oil exchange tank, and the oil storage tank, as well as the suction volume of the oil pump; the three real-time temperature values ​​are assigned the names Ta, Tb, and Tc, and the three constant volume values ​​are assigned the names Va, Vb, and Vc, where Ta and Va, Tb and Vb, and Tc and Vc correspond to the real-time temperature and constant volume values ​​in the return oil tank, the heating tank, and the oil exchange tank, respectively; and the peak value of the oil outlet temperature is assigned the name Ti.

[0011] Further settings: The formula for calculating the temperature rise is: To=(V1*T1+V2*T2) / (V1+V2), where To is the mixed temperature value of the heating chamber or oil change chamber, V1 is the static volume value, V2 is the dynamic replenishment volume value, T1 is the static temperature value, and T2 is the dynamic temperature value.

[0012] Further settings are as follows: Based on the formula for calculating temperature rise, a new formula for calculating temperature rise in the heating chamber is established: ▽T=Tb+Q / (ρ*C*Vb), where ▽T is the dynamic temperature value in the heating chamber, Q is the heat absorbed by the medium in the water bath, C is the specific heat capacity of the medium in the oil tank, and ρ is the density of the medium in the oil tank. C and ρ are constant values. In the formula for calculating temperature rise, V1 is one of Vb or Vc, V2 is one of Va or Vb, T1 is one of Tb, ▽T, and Tc, and T2 is one of Ta, Tb, and ▽T.

[0013] Further configured as follows: During operation, the flow control system, through the flow control unit combined with control signals, performs the following flow control actions:

[0014] Flow control action 1: When Ta > Ti, open the solenoid valve on the U-shaped pipe between the return oil tank and the storage oil tank, while the other solenoid valves are closed, and start the oil suction pump to extract the medium from the storage oil tank.

[0015] Flow control action 2: When Ta < Ti and Tc < Ti, close the solenoid valve on the U-shaped pipe between the return oil tank and the storage oil tank, and keep the other solenoid valves open. Before starting the oil suction pump, apply the temperature rise calculation formula to the oil exchange tank and generate the following formula: Ti > (Vi * Tc + Vc * ▽T) / (Vi + Vc), where Vi is the suction volume of the oil suction pump and Vi is a relative constant value. Thus, the range of ▽T values ​​is calculated in reverse, and the mixed temperature value generated in the oil exchange tank is < To < Ti + 5.

[0016] Flow control action three: Based on flow control action two, the medium in the return oil tank flows into the heating tank, and the temperature rise calculation formula is applied to the heating tank to generate the following formula: To 合= (Vi*Ta+Vb*Tb) / (Vi+Vb), where To 合 The dynamic mixing temperature value in the heating chamber, and To 合 Substituting these values ​​into the temperature rise calculation formula, we get the following formula: Ti = To 合 +Q / (ρ*C*(Vb+Vi))-5, thus calculating Q in reverse;

[0017] Flow control action four: When Tc > Ti, open the solenoid valve on the U-shaped pipe between the oil exchange tank and the oil storage tank, while the other solenoid valves are closed, and start the oil suction pump to extract the medium from the oil storage tank.

[0018] The present invention has the following beneficial effects:

[0019] 1. This invention addresses the oil tank structure in a micro drawing machine, aiming to maintain a stable temperature of the drawing oil within the tank. The overall oil tank structure is improved by dividing it into an oil chamber and a water bath chamber using a partition. The oil chamber is further divided into four areas: a return oil chamber, a heating chamber, an oil exchange chamber, and an oil storage chamber. A return oil suction pump and an oil suction pump are installed for the return oil chamber and the oil storage chamber, respectively. Four U-shaped pipes are added to connect these four areas. To maintain the drawing oil temperature, a water bath is used to heat the heating chamber. The overall purpose of this invention is to achieve gradient control of the same batch of drawing oil, allowing the drawing oil in the four areas to either interfere with or not interfere with each other.

[0020] 2. In conjunction with the above, a temperature control system is simultaneously added, primarily targeting the flow process of the drawing oil in the four areas mentioned above. Based on the drawing oil temperatures in the return oil tank, heating tank, and oil exchange tank, and using the peak oil outlet temperature as a reference, the system utilizes the basic principle of temperature change after mixing two liquids of different temperatures. This temperature control system autonomously controls the flow direction of the drawing oil and the water bath heating temperature. Under the premise of mutual interference, it ensures that the temperature of the drawing oil extracted from the storage tank matches the peak oil outlet temperature, thereby stabilizing the temperature range of the drawing oil acting on the micro-drawing machine and maintaining the drawing quality.

Detailed Implementation

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Regarding the temperature of the drawing oil in a micro drawing machine, the heat generated during drawing is much lower than that of large, medium, and small drawing machines. Therefore, the actual temperature of the drawing oil is low and unstable, and it is also greatly affected by the temperature difference of the external environment. This leads to unstable viscosity of the drawing oil during continuous production, making it easy for the wire to break during drawing, which seriously affects production efficiency and product quality. The following technical solution is proposed to address this issue:

[0030] Reference Figures 1-4 An applicable micro-extrusion machine oil tank improvement device in this embodiment includes an oil tank body 1. A horizontally arranged partition 6 is installed inside the oil tank body 1. An oil tank 9 and a water bath 8 are arranged from top to bottom inside the oil tank body 1 through the partition 6. A water bath box 7 is installed in the water bath 8. A vertically arranged cross-shaped heat insulation layer 10 is installed at the center point of the upper surface of the partition 6. The cross-shaped heat insulation layer 10 is connected to the inner wall of the oil tank body 1. The oil tank 9 is provided with an oil return tank 901, a heating tank 902, an oil exchange tank 903, and an oil storage tank 904 through the cross-shaped heat insulation layer 10. The oil return tank 901, the heating tank 902, the oil exchange tank 903, and the oil storage tank 904 are arranged counterclockwise along the center point of the partition 6.

[0031] Four U-shaped tubes 12 are installed on the cross-shaped insulation layer 10. The four U-shaped tubes 12 are inverted and arranged in a ring array along the center point of the cross-shaped insulation layer 10. The return oil chamber 901 and the heating chamber 902, the heating chamber 902 and the oil exchange chamber 903, the storage oil chamber 904 and the oil exchange chamber 903, and the storage oil chamber 904 and the return oil chamber 901 are connected by the U-shaped tubes 12. The oil tank body 1 is equipped with a temperature detection component, a flow direction control component and a controller 3. The temperature detection component consists of three temperature sensors 2. The three temperature sensors 2 are located on the outside of the oil tank body 1 corresponding to the return oil chamber 901, the heating chamber 902 and the oil exchange chamber 903, respectively, and the probes of the temperature sensors 2 are located inside the return oil chamber 901, the heating chamber 902 and the oil exchange chamber 903.

[0032] The flow control component consists of four solenoid valves 11. The solenoid valves 11 are installed at the upper end of the U-shaped tube 12. The U-shaped tube 12 is connected to the input and output ends of the solenoid valves 11. The solenoid valves 11 are located inside the cross-shaped insulation layer 10. The water bath 7 is located directly below the heating chamber 902. The oil tank body 1 is equipped with a return oil suction pump 4 and an oil suction pump 5 at the positions corresponding to the return oil chamber 901 and the storage oil chamber 904, respectively.

[0033] Operating principle: Please refer to the following for details. Figure 1 and Figure 4 The return oil suction pump 4 is used to return the outflowing drawing oil to the oil tank body 1, while the suction oil pump 5 is used to re-extract the drawing oil from the oil tank body 1 and apply it to the drawing process. The following describes the four areas mentioned above:

[0034] The return oil tank 901 serves as a storage structure for the returned drawing oil, allowing the temperature of the returned drawing oil to be detected by the temperature sensor 2 located at that position.

[0035] The heating chamber 902 can be used as a heating structure in the overall solution, but it only heats the drawing oil in the heating chamber 902 with a water bath and does not affect the other three areas.

[0036] The oil exchange chamber 903 serves as a transfer structure between the heating chamber 902 and the oil storage chamber 904, where the drawing oil in the heating chamber 902 is pumped into the oil exchange chamber 903 for storage.

[0037] As a drawing oil storage structure that meets the temperature requirements, the oil storage tank 904 can be used by the oil suction pump 5 to directly extract the drawing oil from the oil storage tank 904 when the micro drawing machine is started.

[0038] Based on the above, the four regions are connected only by U-shaped pipes 12. When the U-shaped pipes 12 are not connected, the four regions do not interfere with each other. Embodiment 1 serves as the structural basis for Embodiment 2.

[0039] Example 2

[0040] This embodiment, in conjunction with the applicable micro-extraction oil sump improvement device in Embodiment 1, proposes a temperature control system that primarily establishes an autonomous temperature control method based on temperature data. The specific method is as follows:

[0041] The temperature control system uses controller 3 as its operating platform. The temperature control system 3 includes a data collection unit, a data analysis unit, and a flow control unit. The data collection unit collects dynamic and static data and sends them to the data analysis unit. The data analysis unit uses the dynamic and static data to establish a formula for calculating the temperature rise and sets the peak oil outlet temperature. It then combines the calculated data from the temperature rise formula with the peak oil outlet temperature to generate a control signal. The flow control unit uses the control signal from the data analysis unit as a basis to perform flow control actions on the return oil suction pump 4, the suction pump 5, and the solenoid valve 11. The dynamic data includes the real-time displayed temperature values ​​on the three temperature sensors 2 and the heating temperature of the water bath 7. The static data includes the constant volume values ​​of the return oil tank 901, the heating tank 902, the oil exchange tank 903, and the storage tank 904, as well as the suction volume of the suction pump 5. The three real-time displayed temperature values ​​are assigned the values ​​Ta, Tb, and Tc, and the three constant volume values ​​are assigned the values ​​Va, Vb, and Vc. a and Va, Tb and Vb, and Tc and Vc correspond to the real-time displayed temperature and constant volume values ​​in the return oil tank 901, heating tank 902, and oil exchange tank 903, respectively. The peak oil outlet temperature is assigned the value Ti. The formula for calculating the temperature rise is: To = (V1*T1 + V2*T2) / (V1 + V2), where To is the mixed temperature value of heating tank 902 or oil exchange tank 903, V1 is the static volume value, V2 is the dynamic replenishment volume value, T1 is the static temperature value, and T2 is the dynamic temperature value. The calculation is based on the temperature rise... The calculation formula for the temperature rise in the heating chamber 902 is re-established as follows: ▽T=Tb+Q / (ρ*C*Vb), where ▽T is the dynamic temperature value in the heating chamber 902, Q is the heat absorbed by the medium in the water bath 7, C is the specific heat capacity of the medium in the oil tank 9, and ρ is the density of the medium in the oil tank 9. C and ρ are constant values. In the temperature rise calculation formula, V1 is one of Vb or Vc, V2 is one of Va or Vb, T1 is one of Tb, ▽T, and Tc, and T2 is one of Ta, Tb, and ▽T.

[0042] During operation, the flow control actions executed by the flow control unit in conjunction with control signals in the temperature control system include the following:

[0043] Flow control action 1: When Ta > Ti, open the solenoid valve 11 on the U-shaped pipe 12 between the return oil tank 901 and the storage oil tank 904, while the other solenoid valves 11 are closed, and start the oil suction pump 5 to extract the medium from the storage oil tank 904.

[0044] Flow control action 2: When Ta < Ti and Tc < Ti, close the solenoid valve 11 on the U-shaped pipe 12 between the return oil tank 901 and the storage oil tank 904, and keep the other solenoid valves 11 open. Before starting the oil suction pump 5, apply the temperature rise calculation formula to the oil exchange tank 903 and generate the following formula: Ti > (Vi * Tc + Vc * ▽T) / (Vi + Vc), where Vi is the suction volume of the oil suction pump 5 and Vi is a relative constant value. Thus, the range of ▽T values ​​is calculated in reverse, and the mixed temperature value generated in the oil exchange tank 903 is 0 < To < Ti + 5.

[0045] Flow control action three: Based on flow control action two, the medium in the return oil tank 901 flows into the heating tank 902, and the temperature rise calculation formula is applied to the heating tank 902 to generate the following formula: To 合 = (Vi*Ta+Vb*Tb) / (Vi+Vb), where To 合 The dynamic mixing temperature value in the heating chamber 902, and To 合 Substituting these values ​​into the temperature rise calculation formula, we get the following formula: Ti = To 合 +Q / (ρ*C*(Vb+Vi))-5, thus calculating Q in reverse;

[0046] Flow control action four: When Tc > Ti, open the solenoid valve 11 on the U-shaped pipe 12 between the oil exchange tank 903 and the oil storage tank 904, while the other solenoid valves 11 are closed, and start the oil suction pump 5 to extract the medium from the oil storage tank 904.

[0047] Referring to the description in Embodiment 1, the four areas are connected via U-shaped pipes 12 to achieve the following connections: oil return chamber 901 and heating chamber 902, heating chamber 902 and oil exchange chamber 903, oil storage chamber 904 and oil exchange chamber 903, and oil storage chamber 904 and oil return chamber 901. However, when the solenoid valve 11 on one of the U-shaped pipes 12 is in the closed state, the U-shaped pipe 12 is in the closed state. The technical advantages of this, as further explained above, are as follows:

[0048] When the drawing oil is extracted and applied to the drawing action, the temperature of the drawing oil drops significantly due to heat loss, and it will flow back to the return oil tank 901. According to the flow control action mentioned above, when Ta > Ti, it is not necessary to heat the drawing oil in a water bath, so the drawing oil stored in the return oil tank 901 can be used directly. This part will not be elaborated further.

[0049] It is important to note that when the flow direction control action one is not met, the drawing oil needs to be heated. The drawing oil in the return oil tank 901 flows in the following manner: return oil tank 901 - U-tube 12 - heating tank 902 - U-tube 12 - oil exchange tank 903 - U-tube 12 - oil storage tank 904. This can be understood as a dual change in both the volume and temperature of the drawing oil in a certain area. The volume change will not be elaborated upon, but the temperature change needs to be explained. Specifically, it refers to the formula: To = (V1*T1 + V2*T2) / (V1 + V2), which represents the temperature change after two liquids of the same medium but different temperatures are mixed. This formula is a key point in this embodiment. For example, a portion of the drawing oil collects from the return oil tank 901 into the heating tank 902. Further explanation is needed regarding this process:

[0050] Regarding the above-mentioned flow control actions two and three, this part only applies to situations where the temperature of the drawing oil in the heating chamber 902 is still lower than Ti after the drawing oil has been collected in the heating chamber 902. Only then will the water bath heating method be activated. However, if the temperature of the drawing oil in the heating chamber 902 is greater than or equal to Ti, it means that the drawing oil in the heating chamber 902 can be used for drawing action.

[0051] It still needs further explanation that the overall drawing oil connection method in the device is based on the principle that the oil suction pump 5 extracts a portion of the drawing oil, and with the connection of the four U-shaped pipes 12, the theoretical oil level in the four areas is equal. Regarding the dynamic balance of the drawing oil volume, for example, when volume V of drawing oil is extracted from the oil storage tank 904, and the return oil suction pump 4 is not started (the drawing oil is not replenished), then theoretically the volume in the return oil tank 901, heating tank 902, and oil storage tank 903 needs to decrease. V / 3, but in this embodiment, it is necessary to limit the suction volume of the return oil suction pump 4 and the suction volume of the oil suction pump 5 to be equal in order to maintain the dynamic balance of the drawing oil volume. However, in this embodiment, the dynamic balance can be broken by closing the solenoid valve 11 at a certain position. For example, in the flow direction control action two to flow direction control action four, the solenoid valve 12 between the return oil chamber 901 and the heating chamber 902 and the oil storage chamber 904 is closed. Then, in this process, only the heating chamber 902, the oil changing chamber 903 and the oil storage chamber 904 achieve dynamic balance.

[0052] Therefore, using the formulas To = (V1*T1 + V2*T2) / (V1 + V2) and ▽T = Tb + Q / (ρ*C*Vb), since V1 is either Vb or Vc, V2 is either Va or Vb, T1 is either Tb, ▽T, or Tc, and T2 is either Ta, Tb, or ▽T, we can regenerate, for example, the formulas (Vi*Tc + Vc*▽T) / (Vi + Vc) and To. 合=(Vi*Ta+Vb*Tb) / (Vi+Vb)、Ti=To 合 The formulas +Q / (ρ*C*(Vb+Vi))-5 and related formulas require explanation. The following formulas need symmetry: To=(V1*T1+V2*T2) / (V1+V2) and ▽T=Tb+Q / (ρ*C*Vb) are the basic formulas in this embodiment. However, the variables include V1, V2, T1, and T2. Based on the values ​​of the three temperature sensors 2 and Ti, corresponding calculation formulas are generated. The variables switch according to the connection state of the corresponding solenoid valve 12. These will not be explained individually in this embodiment. Their main purpose is to control the heating temperature of the water bath 7. When the drawing oil temperature is lower than Ti, the heating temperature is controlled to maintain a stable drawing oil temperature.

[0053] In summary: For the oil bath used in the micro-drawing machine to maintain stable drawing oil temperature, the overall oil bath structure is first improved. Specifically, the bottom layer is used as a water bath layer, and the top layer as an oil tank. A cross-shaped insulation layer divides the oil tank into four areas: a return oil tank, a heating tank, an oil exchange tank, and an oil storage tank. U-shaped pipes and solenoid valves are used to connect or close these four areas. Based on this, temperature data from the return oil tank, heating tank, and oil exchange tank are used to generate control signals, which, in conjunction with the drawing oil temperature in the micro-drawing machine, aim to ensure that the drawing oil temperature is balanced with the peak output temperature. This is achieved by using a water bath heating method and restricting the flow of the drawing oil to achieve temperature balance.
