Description

Technical Field

[0001] The invention relates to the technical field of wire cutting processing, in particular to a medium-speed wire automatic wire removal and threading device. Background Art

[0002] Wire cutting, also known as wire-cutting electrical discharge machining, is a special processing method that uses electric spark discharge to cut conductive materials. It plays an important role in modern industrial production, especially in mold manufacturing, precision machinery parts processing and other fields.

[0003] The basic principle of wire cutting is to use a continuously moving thin metal wire (called electrode wire) as a tool electrode to perform pulse spark discharge to erode the metal of the workpiece, thereby achieving cutting processing. During the processing, a certain discharge gap is always maintained between the electrode wire and the workpiece, usually a few microns to tens of microns. When a pulse voltage is applied between the electrode wire and the workpiece, a high-temperature and high-pressure electric spark discharge will be generated in a very short time, causing the local metal on the surface of the workpiece to melt and vaporize instantly and be thrown out, thereby forming tiny pits. By constantly repeating this process, the electrode wire moves along a predetermined trajectory, and the workpiece can be gradually cut into the desired shape.

[0004] The wire cutting process has the following notable characteristics: First, high processing accuracy. Whether it is fast wire or slow wire, it can achieve high dimensional accuracy and shape accuracy. In particular, slow wire cutting can meet the processing requirements with extremely high precision. This makes the wire cutting process irreplaceable in precision mold manufacturing and complex parts processing. Secondly, it has strong adaptability. Wire cutting can process conductive materials of various hardness, including high-hardness hardened steel, cemented carbide, etc. For parts with complex shapes, sharp corners, narrow gaps, etc. that are difficult to process with traditional machining methods, the wire cutting process can also easily cope with it. Furthermore, there is no cutting force during the processing process. Since wire cutting removes metal through electric spark discharge, it does not rely on cutting force like traditional machining, so there will be no deformation caused by cutting force. This is very beneficial for processing thin-walled parts, elastic parts, etc. In addition, the wire cutting process also has the advantage of high degree of automation. Modern wire cutting equipment is usually equipped with advanced CNC systems, which can realize automatic programming and processing of complex shapes, greatly improving production efficiency and processing accuracy.

[0005] However, the traditional manual threading method has exposed many problems in practical applications, seriously affecting production efficiency and processing quality.

[0006] First of all, manual wire removal is extremely cumbersome. Operators need to rely on experience and skills to carefully thread and remove the electrode wire. This process is not only time-consuming and laborious, but also requires a high level of skill from the operator. For complex workpieces or high-precision processing requirements, the difficulty of manual wire removal is further increased, and it often takes repeated attempts to succeed, which greatly wastes time and labor costs.

[0007] Secondly, the accuracy of manual wire removal is difficult to guarantee. During manual operation, it is easily affected by human factors, such as hand shaking, line of sight deviation, etc. These factors may cause inaccurate position of the electrode wire and affect the processing accuracy. Especially in some precision processing fields with extremely high precision requirements, the insufficient accuracy of manual wire removal may lead to substandard product quality and even require reprocessing, which increases production costs.

[0008] Furthermore, manual wire removal is less safe. When the operator manually removes the wire, he needs to directly contact the electrode wire and the processing equipment, which poses certain safety risks. For example, he may be scratched by the sharp electrode wire, or the equipment may fail due to improper operation, posing a threat to the operator's personal safety. Summary of the invention

[0040] The upper surface of the first XY axis motion mechanism 2 is fixedly connected with a column 4, and the upper surface of the column 4 is fixedly connected with a UVZ axis motion mechanism 5.

[0041] The front of the UVZ-axis motion mechanism 5 is fixedly connected with an upper clamping wheel conveying device 6, which is controlled to move up and down by the UVZ-axis motion mechanism 5. The upper clamping wheel conveying device 6 uses a high-wear-resistant roller, combined with a motor drive, to clamp or release according to control signals and pulse instructions and convey the electrode wire according to a corresponding distance length through the workpiece to the corresponding position of the lower head.

When the electrode wire passes through the workpiece, the lower guide on the waste removal device 11 will rise according to the control, and the electrode wire is sent through the raised lower guide and then passes through the guide eye mold until the lower clamping wheel conveyor 10. The traditional wire dismantling equipment is a fixed eye mold veneer method or an eye mold up and down movement method. The former cannot effectively remove the waste after taking out the processing, and the latter is difficult to guarantee the accuracy of repeated use. The present invention uses a mobile guide slide combined with a fixed eye mold to solve the problem of guiding the removal of waste, and effectively guarantee the accuracy problem for a long time, and the repeated operation is more stable and reliable.

[0044] A counterweight mechanism 12 is fixedly connected to the front side of the column 4.

When the wire is removed and threaded, the cylinder is used to move the counterweight mechanism 12 according to the instructions, and participates in the auxiliary determination of the position of the electrode wire, thereby ensuring the accuracy of the real-time position of the electrode wire.

[0047] In the detection mechanism 15, the sensor includes: 1. Light-emitting element: such as light-emitting diode, which emits light of a specific wavelength; 2. Receiving element: such as phototransistor, which receives the light emitted by the light-emitting element and converts it into an electrical signal. When the electrode wire passes through the detection area of ​​the photoelectric sensor, it blocks the light, thereby causing a change in the electrical signal output by the receiving element, thereby detecting the position of the electrode wire; 3. Sensing element: It can be inductive, capacitive or Hall effect, etc. When the electrode wire approaches the sensing element, it causes changes in parameters such as the electromagnetic field or capacitance of the sensing element, thereby detecting the position of the electrode wire.

[0048] The signal processing module includes: 1. Amplifier: amplifies the weak signal output by the sensor for subsequent processing, 2. Filter: removes noise interference in the signal and improves the quality of the signal, 3. Analog-to-digital converter (ADC): converts the analog signal into a digital signal for processing by the digital circuit.

[0049] The controller is used to receive the digital signal from the signal processing part, analyze and process it, determine whether the position of the electrode wire is correct, and send out a control signal as needed. At the same time, the display screen on the controller is used to display the position information of the electrode wire for the operator to observe. The detection mechanism 15 uses traditional mechanical design with corresponding moving structural parts and the system to cooperate in detecting the corresponding position of the electrode wire.

[0053] The signal transmission module includes: 1. Transmission cable: usually high-frequency coaxial cable is used, which has good high-frequency signal transmission characteristics and can effectively transmit the pulse signal from the signal source to the electrode wire. The coaxial cable is composed of an inner conductor, an insulating layer, an outer conductor and a sheath. The inner conductor is used to transmit the signal, and the outer conductor plays a shielding role to reduce external interference. 2. Matching circuit: In order to ensure that the pulse signal can be effectively transmitted to the electrode wire, a matching circuit needs to be added to the transmission path. The matching circuit is usually composed of inductors, capacitors and other components, which are used to adjust the impedance of the transmission line to match the impedance of the pulse signal source and the electrode wire to reduce signal reflection and loss.

[0054] The signal output module includes: 1. Electrode wire clamp: used to fix the electrode wire on the high-frequency conduction device 17 and ensure good electrical contact. The electrode wire clamp is usually made of conductive materials, such as copper, tungsten, etc., with good conductivity and wear resistance. 2. Contact electrode: directly contacting the electrode wire and transmitting the pulse signal to the electrode wire. The contact electrode is usually made of wear-resistant and conductive materials, such as graphite, copper-tungsten alloy, etc., to ensure long-term stable signal transmission.

[0055] The protective shell is used to protect the internal structure of the high-frequency conduction device 17 and prevent the external environment from damaging the device. The protective shell is usually made of metal or plastic materials and has good mechanical strength and protective performance. The guide frame guides the electrode wire and transmits the pulse signal to the processing electrode wire through the high-frequency conduction device 17 for application.

[0056] In the present invention, when the device is threading the wire, the electrode wire is guided by the upper guide tube 7 and the lower guide tube 9, and then the electrode wire is conveyed by the upper clamping wheel conveying device 6 and the lower clamping wheel conveying device 10.
