Description

Technical Field

[0001] The invention relates to the technical field of fusion welding machines, in particular to a temperature-controlled PSP steel-plastic pipe electromagnetic fusion welding machine. Background Art

[0002] When working, the traditional fusion welding machine mainly includes key components such as power supply, transformer, electrode and electrode clamp. The power supply is responsible for providing the necessary electrical energy, while the transformer converts this electrical energy into a high current suitable for the fusion welding process. The function of the electrode is to transfer the current to the metal material fixed by the electrode clamp, thereby generating heat at the contact point of the material, heating it to the melting point, so as to weld two or more metal materials together;

[0003] However, this traditional fusion welding method has some significant problems, mainly manifested in the extremely high current stability requirements. For example, if the arc is too long, pores may appear in the welding area; if the welding current is too small, the welding materials may not be fully fused; and if the current is too large, it may cause welding defects such as undercut and weld nodules. In addition, this method is usually accompanied by the problems of low welding efficiency and slow heating speed, which affects the consistency and reliability of welding quality. At the same time, it also consumes a lot of electricity, does not meet the environmental protection requirements of energy conservation and emission reduction, and is relatively inconvenient in operation. With the improvement of on-site installation and construction technical requirements, traditional fusion welding machines have become increasingly unable to meet the needs of modern industrial production.

[0048] A multifunctional heat dissipation mechanism 4 is installed on the welding machine body 101;

[0049] The multifunctional heat dissipation mechanism 4 includes strip frames 401 fixed on the upper surface of the welding machine body 101 and arranged symmetrically, a rotating rod rotatably connected between two groups of strip frames 401 through a bearing, and a plate body 1 402 fixed on the rotating rod;

[0050] One side of the plate body 1 402 is rotatably connected with the plate body 2 403 through a bearing, and a cooling fan 404 is installed on the plate body 2 403. An air vent 405 corresponding to the cooling fan 404 is provided on the upper surface of the welding machine body 101. A rotating disk 410 is fixed at one end of the rotating rod. The edge surface of the rotating disk 410 is provided with a plurality of groups of equally spaced card slots 411. One group of the strip frames 401 is provided with an L-shaped through groove, and a sliding rod 406 is provided in the L-shaped through groove. A square block 408 slides on the surface of the sliding rod 406. A card 409 is fixed on one side of the square block 408. The card 409 is stuck in the card slot 411 provided in one group of the rotating disks 410 for locking the position of the rotating disk 410. A spring 3 407 is wound around the surface of the sliding rod 406. The two ends of the spring 3 407 are respectively fixedly connected to the square block 408 and the strip frame 401, and the sliding rod 406 is fixedly connected to the strip frame 401.

[0051] A fixing pin 413 is fixed on one side of the upper surface of the second plate body 403 close to the first plate body 402, and the surface of the fixing pin 413 is rotatably connected to a blocking piece 412 through a bearing, and a second return torsion spring 414 is wound around the surface of the fixing pin 413, and the two ends of the second return torsion spring 414 are fixedly connected to the blocking piece 412 and the fixing pin 413 respectively;

[0052] The lower surface of the blocking piece 412 is flush with the plate body 1 402 and the plate body 2 403 respectively;

[0053] A mounting plate 105 is fixedly installed inside the welding machine body 101 , and the wireless transmission communication module 106 and the electromagnetic heating execution module 107 are both installed on the surface of the mounting plate 105 .

[0054] In this embodiment: when the temperature-controlled PSP steel-plastic pipe electromagnetic welding machine is used, first, the plug of the electromagnetic coil 102 is aligned with the socket 109, and then the plug of the electromagnetic coil 102 is pushed. When the strip plate 301 contacts the inclined surface of the buckle plate 305, the roller 304 on the strip plate 301 slides on the inclined surface of the buckle plate 305 during the process of pushing the plug of the electromagnetic coil 102 to move. Since the upper surface of the buckle plate 305 is designed with an inclined surface structure, when the strip plate 301 drives the roller 304 on the L-shaped side plate 303 to move on the inclined surface of the buckle plate 305, the strip plate 301 continuously tilts upward, and at the same time drives the reset torsion spring 304 to move upward. 2 generates torsional deformation. When the roller 304 corresponds to the buckle groove 306 provided on the buckle plate 305, when the reset torsion spring 1 302 is reset, the strip plate 301 is driven to tilt downward, and the roller 304 is driven to be stuck in the buckle groove 306. When the roller 304 is on the buckle groove 306, the plug of the electromagnetic coil 102 is completely inserted into the socket 109, and the roller 304 is stuck in the buckle groove 306, so that the electromagnetic coil 102 and the socket 109 can be connected and locked, thereby preventing the electromagnetic coil 102 from being pulled and affecting the connection between the electromagnetic coil 102 and the socket 109, effectively preventing the electromagnetic coil 102 from falling off, and improving the use effect of this structure;

[0055] When the electromagnetic coil 102 plug is inserted into the socket 109, the push rod 308, the resistance rod 310 and the second spring 309 are driven to move synchronously. At this time, the resistance rod 310 is in conflict with the welding machine body 101 and is blocked by the resistance rod 310. At this time, the resistance rod 310 drives the push rod 308 to slide on the fixed block 307 and compresses the second spring 309. When the electromagnetic coil 102 plug and the socket 109 are disassembled, the strip plate 301 is swung at this time, so that the roller 304 on the strip plate 301 is separated from the buckle groove 306. At this time, the second spring 309 in a compressed state rebounds and drives the electromagnetic coil 102 plug and the socket 109 to separate quickly, thereby improving the separation effect and achieving a better use effect.

[0056] When the plugs at both ends of the electromagnetic coil 102 are inserted into the socket 109, the electromagnetic coil 102 is then wound around the welding area of ​​the steel-plastic pipe body 103, and at the same time, the thermal resistor PT100 inside the welding machine body 101 is pulled out and fixedly placed in the welding area of ​​the steel-plastic pipe body 103 (a special clamp is used to fix the thermal resistor PT100 on the steel-plastic pipe. The clamp can be mechanical, fixed by screws, or spring-loaded to ensure that the thermal resistor PT100 is in close contact with the surface of the steel-plastic pipe body 103). The thermal resistor PT100 is a temperature probe, usually used to measure temperature. The PT100 thermal resistor is set on the PSP steel-plastic pipe electromagnetic fusion welding machine. Its purpose is to monitor and control the temperature of the steel-plastic pipe body 103 during the fusion welding process, and to monitor the temperature change of the steel-plastic pipe body 103 during the fusion welding process in real time. During this process, the resistance change of the thermal resistor PT100 needs to be converted through a conversion The circuit converts the resistance change into an electrical signal. Usually, this involves a bridge circuit (such as a Wheatstone bridge) that converts the resistance change into a voltage change. This voltage signal is proportional to the temperature. The converted electrical signal is usually very weak and needs to be amplified by an amplifier and the noise is removed by a filter to improve the accuracy of the signal. The amplified and filtered electrical signal will be sent to an analog-to-digital converter (ADC). The ADC converts the analog signal into a digital signal. A computer or microprocessor can process these digital signals. The microprocessor or central processing unit (CPU) will process the digital signal and convert the voltage value into a temperature value according to the resistance-temperature characteristic curve of the thermal resistor PT100. The processed temperature value will be sent to the liquid crystal display 108 for display. The liquid crystal display 108 can be an LCD, LED or other type of display. According to the user's settings, the current temperature can be displayed in the form of numbers or charts;

[0057] After the electromagnetic coil 102 is wound on the surface of the steel-plastic pipe body 103, during this process, the pressing block 206 is pressed, thereby driving the connecting rod 203 to move downward, and at the same time, the spring 1 205 is stretched through the expansion disk 204, and the connecting rod 203 drives the resisting arc-shaped piece 202 to move downward, releasing the squeezing of the surface of the electromagnetic coil 102, and then starting the connecting plate 201, moving the connecting plate 201 to the kink of the electromagnetic coil 102 wound around the steel-plastic pipe body 103, and then releasing the pressing block 206, and releasing the squeezing of the connecting rod 203. The spring 105 contracts and drives the arc-shaped piece 202 to move upward, and then the surface of the electromagnetic coil 102 is squeezed by the arc-shaped piece 202 to lock the electromagnetic coil 102 wound on the surface of the steel-plastic pipe body 103, thereby avoiding the occurrence of fluffy conditions, ensuring that the electromagnetic coil 102 is firmly fixed at a specific position of the steel-plastic pipe, avoiding the displacement of the coil during the heating process, thereby ensuring the accuracy of the heating position and the welding quality, reducing the safety risks in the operation, and improving the safety of the overall operation;

[0058] Then, the welding parameters, such as heating power, heating time, etc., are set through the LCD screen 108. After the input is completed, it is confirmed that the parameter settings are correct, and the electromagnetic heating execution module 107 is started to start heating the steel-plastic pipe body 103. The wireless transmission communication module 106 can remotely monitor and control during this process and adjust the heating parameters. The thermal resistor PT100 (not shown in the figure) will measure the temperature of the welding area in real time and transmit the data to the control unit (not shown in the figure). The control unit adjusts the heating power according to the set welding curve and real-time temperature data to ensure accurate temperature control. When the temperature of the welding area reaches the preset value, in this process, through the setting of the electromagnetic coil 102, the metal pipe section of the steel-plastic pipe body 103 cuts the alternating magnetic field lines to generate alternating current, i.e., eddy current. The eddy current causes the carriers of the metal pipe section of the steel-plastic pipe body 103 to move irregularly at high speed. The carriers collide and rub with atoms to generate heat energy, thereby heating the steel-plastic pipe body 103, so that the material of the steel-plastic pipe body 103 is locally heated and melted, and the molten material will form a molten pool at the joint. As the heating continues, the materials in the molten pool will be fully mixed to achieve welding.

[0059] The electromagnetic heating mode can quickly transfer energy to the heating material, so that no other auxiliary materials are needed for heating. The electromagnetic waves can make the steel-plastic pipe material heat up by itself, which greatly reduces the difficulty of welding, automatically controls the welding temperature, and automatically identifies the interference of various environments on the welding temperature, accurately achieving precise welding effects. Compared with the heating method using gas or liquid fuel, the electromagnetic heating mode does not require these traditional fuels, so there is no emission of any pollutants during the heating process, which is more environmentally friendly and helps to achieve the goal of energy conservation and emission reduction. Since electromagnetic heating can achieve instantaneous heating, the metal material can quickly reach the melting point, thereby ensuring stable and strong welding quality. Compared with traditional heating methods, electromagnetic heating is not easy to produce welding defects such as pores and weld nodules. At the same time, the microstructure of the metal material changes little, maintaining the original characteristics of the material;

[0060] When the welding machine body 101 is in use, the cooling fan 404 can be used to cool the inner cavity components of the welding machine body 101. The heat dissipation can prevent the internal temperature of the welding machine body 101 from being too high, ensure that the electronic components of the welding machine body 101 operate within the normal operating temperature range, and avoid equipment failure caused by overheating. After the electromagnetic fusion welding machine is completed, the square block 408 is slid on the sliding rod 406 by sliding the square block 408, and the spring 407 is compressed at the same time. At the same time, the square block 408 drives the card 409 to move synchronously, so that the card 409 is inserted from the card slot 410 provided on the rotating disk 410. 1 is disengaged, thereby releasing the lock of the rotating disk 410, and then the second plate body 403 is folded, thereby driving the cooling fan 404 to be folded synchronously, and at the same time, the second plate body 403 drives the first plate body 402 to be folded, and the first plate body 402 drives the rotating disk 410 to rotate through the rotating rod until the second plate body 403 is turned to a certain angle, and then the square block 408 is released. At this time, the spring three 407 rebounds and drives the square block 408 and the card 409 to be stuck in the matching card slot 411, thereby completing the locking of the rotating disk 410, and then completing the locking of the first plate body 402, and then rotating the fixing pin 413 The blocking piece 412 on the plate body 403 is then driven to twist the reset torsion spring 414, so that the reset torsion spring 414 produces a certain elastic deformation, and then the blocking piece 412 is completely folded on the plate body 403, thereby releasing the lock of the plate body 403 and the plate body 403, and then the plate body 403 is turned over to 180 degrees, and then the blocking piece 412 is released, and the elastic reset of the reset torsion spring 414 drives the blocking piece 412 to reset, thereby locking the plate body 1 402 and the plate body 2 403. At this time, the plate body 403 drives the cooling fan 404 to turn its direction, and then the electromagnetic coil 10 2 and the steel-plastic pipe body 103 are moved to the position below the heat dissipation fan 404 to dissipate the heat of the electromagnetic coil 102 and the steel-plastic pipe body 103. The heat dissipation fan 404 can discharge the heat generated inside the welding machine body 101 in time when working, protect sensitive electronic components from high temperature, and enable the electromagnetic fusion welding machine to continuously and stably output power to ensure welding quality. When the welding process is completed, the heat dissipation fan 404 can be folded to the specified position to help quickly reduce the temperature of the welding area and the electromagnetic coil 102, reduce the potential impact of heat on materials, and improve the multifunctional use of the heat dissipation fan 404.

[0061] It should be noted that: there is no need to use open flames for heating, the operation process is relatively safe, and the equipment is equipped with a liquid crystal display 108, which can monitor and feedback the temperature in real time, making the operation more intuitive and easy to use.

[0062] At the same time, a wireless transmission communication module 106 and a non-contact wireless temperature measurement technology are provided, which facilitates the on-site operator to grasp the welding status in real time, thereby improving the welding quality and success rate of the fusion welding machine;

[0063] The electromagnetic heating execution module 107 includes a high-frequency power generator, a controller and a protection circuit. The high-frequency power generator generates high-frequency current to supply the induction coil to generate sufficient magnetic field strength for heating. The controller is responsible for controlling the entire electromagnetic heating process, including starting, stopping, power adjustment, etc. The protection circuit is used to monitor the working status of the system. Once an abnormality (such as overtemperature, overload, etc.) is detected, the power supply will be cut off immediately to protect the safety of the equipment and operators.
