Description

Technical Field

[0001] The invention relates to metal wire processing equipment, in particular to a six-die wire drawing machine. Background Art

[0002] As an important conductive material, copper rods are widely used in the fields of electricity, electronics and communications. In the production process of copper rods, it is usually necessary to reduce the diameter through wire drawing to achieve the required diameter specifications. Existing wire drawing machines mostly use a single drawing die, or adjust the speed and angle of the traction wheel manually or mechanically during the drawing process, which not only increases the complexity of operation, but may also lead to low production efficiency and fluctuations in product quality.

[0003] In addition, the traditional wire drawing machine has deficiencies in the tension control between the dies, resulting in uneven tension during the wire drawing process, which can easily cause wire breakage, deformation and other problems, thus affecting the stability of production and the quality of the product. Therefore, a new type of wire drawing machine is urgently needed to improve production efficiency, improve drawing quality, and achieve more precise tension control. Summary of the invention

[0004] In order to solve the problems of uneven tension, inaccurate speed adjustment and unadjustable wire splitting angle of wire drawing machines in the prior art, the present invention provides a six-die wire drawing machine.

[0007] For the traction wheel with adjustable angle, the effect of the line splitting operation is adjusted by adjusting the angle θ i To reflect:

[0008]

[0009] Among them, f(θ i ) is a function related to the adjustment angle, T i is the torque of the ith traction wheel (unit: Newton meter, N·m), and R is the radius of the traction wheel (unit: meter, m).

[0010] Furthermore, the pulling speed is controlled by adjusting the parameters of the tension device. The relationship between the tension T and the pulling speed v is expressed by the following formula:

[0014] v is the pulling speed (unit: meter / second, m / s)

[0015] d is the diameter of the copper rod (unit: meter, m)

[0016] k is a constant related to material properties and tension device parameters (unit: Newton·second / meter, N·s / m)

[0017] By adjusting the parameter k of the tension device, the pulling speed v can be controlled to ensure that the tension T remains uniform during the drawing process.

[0018] Furthermore, the tension device includes an upper tension wheel and a lower tension wheel.

[0019] The six-die wire drawing machine is equipped with an automatic control system, which includes a tension sensor, a speed sensor, a traction sensor and a PLC industrial computer.

[0020] A tension sensor is installed near the tension wheel and is used to detect the tension of the tension device;

[0021] The speed sensor is installed on the traction wheel to detect the speed of the wire passing through;

[0022] The traction force sensor is installed on the traction wheel and is used to detect the traction force;

[0023] The sensor signal is transmitted to the PLC industrial computer, and the PLC industrial computer controls the motor to adjust the speed, the pneumatic device to adjust the tension, and the traction wheel to adjust the traction force.

[0024] Furthermore, the device may also be equipped with a cooling box.

[0025] Compared with the prior art, the beneficial effects of the present invention are: by improving the number of molds, traction wheel design, tension control and wire splitting mechanism, the implementation of the invention can improve the stability, accuracy and efficiency of the copper rod diameter reduction drawing process, thereby significantly improving product quality and reducing production costs.

[0026] (1) Accurate control of wire splitting angle: The adjustable angle design of the traction wheel makes the wire splitting process more accurate, avoiding the problem of uneven wire splitting in traditional wire drawing machines, thereby improving the drawing accuracy and appearance quality of the copper rod.

[0027] (2) Improve the drawing quality of copper rod: The tension device controls the traction force between each two dies, ensuring uniform tension during the drawing process, avoiding breakage or deformation of the copper rod due to uneven tension, and improving the stability and consistency of the product.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-3 The six-die wire drawing machine of the present invention comprises six wire drawing stations 1, each of which is provided with a wire drawing die 2 and two traction wheels, the two traction wheels are respectively an adjustable angle traction wheel 3 and a traction wheel 4, and a tension device 5 is arranged between every two wire drawing dies.

[0035] The adjustable angle range of the adjustable angle traction wheel 3 is 2-5°.

[0036] The tension device 5 includes an upper tension wheel 51 and a lower tension wheel 52 .

[0037] The traction wheel of each station has independent power, which can provide the required traction force, and control the speed between each two dies through the tension device 5, so as to accurately control the drawing process of the copper rod.

[0038] By adjusting the parameters of the tension device, the pulling speed between each two dies (stations) is controlled to ensure uniform tension during the drawing process and prevent the copper rod from breaking or deforming;

[0039] The pulling speed is controlled by adjusting the parameters of the tension device to ensure uniform tension during the drawing process. The relationship between the tension T and the pulling speed v is expressed by the following formula:

[0040]

[0041] in:

[0042] T is the tension (unit: Newton, N)

[0043] v is the pulling speed (unit: meter / second, m / s)

[0044] d is the diameter of the copper rod (unit: meter, m)

[0045] k is a constant related to material properties and tension device parameters (unit: Newton·second / meter, N·s / m)

[0046] The tension T is proportional to the pulling speed v and inversely proportional to the diameter d of the copper rod. By adjusting the parameter k of the tension device, the pulling speed v can be controlled to ensure that the tension T remains uniform during the drawing process and prevent the copper rod from breaking or deforming.

[0047] Each drawing station has a powered traction wheel, and one of the traction wheels is adjustable for wire splitting. The adjustability of the traction wheel angle can be adjusted according to production needs, thereby effectively splitting the wire and ensuring stability during the wire drawing process.

[0048] For traction wheels with adjustable angles, the effect of the line splitting operation can be adjusted by adjusting the angle θ i To reflect.

[0049] Among them, f(θ i ) is a function related to the adjustment angle, T i is the torque of the ith traction wheel (unit: Newton meter, N·m), and R is the radius of the traction wheel (unit: meter, m).

[0050] This formula describes how the traction force of the traction wheel is adjusted to perform line splitting operations, and takes into account the dynamic characteristics of the traction wheel.

[0051] The six-die wire drawing machine is equipped with an automated control system that can monitor tension, speed and traction in real time and automatically adjust working parameters to maintain accuracy and stability during the wire drawing process.

[0052] The automatic control system includes tension sensor, speed sensor, traction sensor and PLC industrial computer.

[0053] The tension sensor is installed near the tension wheel to detect the tension of the tension device to ensure the wire tension is stable during the drawing process to prevent breakage or deformation;

[0054] The speed sensor is installed on the traction wheel to detect the speed of the wire passing through;

[0055] The traction force sensor is installed on the traction wheel and is used to detect the traction force;

[0056] The sensor signal is transmitted to the PLC industrial computer, and the PLC industrial computer controls the motor to adjust the speed, the pneumatic device to adjust the tension, and the traction wheel to adjust the traction force.

[0057] The traction wheel at each workstation is designed with an adjustable angle, which allows the copper rod to be evenly divided during the drawing process, reducing unnecessary tension fluctuations and ensuring high precision and stability in the copper rod diameter reduction process.

[0058] The equipment can also be equipped with a cooling box 6 for temperature control during the wire drawing process to ensure that the copper rod will not be deformed or damaged due to overheating during the drawing process.

[0059] Advantages of the present invention:
