Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of simulation assessment, in particular to a device for simulating melting welding and thermal cutting. Background Art
[0002] Fusion welding involves melting the metal at the joint under conditions such as high temperatures, creating a strong weld joint. Because the workpieces are held tightly together, the molten metal from the two workpieces mixes under the influence of temperature and gravity, without the application of pressure. Once the temperature drops, the molten metal solidifies, firmly joining the two workpieces and completing the welding process.
[0003] Thermal cutting uses concentrated heat energy to melt or burn materials and separate them. Thermal cutting is widely used in industry for cutting metal materials, processing parts, breaking up scrap, and installing and removing materials. Because thermal cutting is directly related to welding, using the same heat source equipment and often used for cutting weldments and beveling joints before welding, it is often considered part of the welding technology field.
[0004] Traditional welding exams, due to limitations in training methods and environments, often rely on theoretical questions. This fails to assess students' actual operational performance and only assesses theoretical knowledge. This results in students lacking practical experience, hindering their mastery of welding knowledge and skills. To address this issue, a simulated melting welding and thermal cutting device is proposed. Utility Model Content
[0005] The technical problem to be solved by the present invention is to provide a simulated melting welding and thermal cutting equipment, which can simulate the welding process by simulating the combined operation of a welding and cutting gun group and a simulated welding machine, and simulate the welding process by sliding a front touch head installed at the front end of the gun body on a touch screen integrated machine, thereby playing an assessment role in the welding operation, and can simulate and assess other necessary operations through a welding operating table and an operable simulated gas meter, thereby solving the technical problem that it is difficult to assess the practical ability of examinees through simulation means in the existing technology for welding examinations, resulting in students' lack of practical experience, which is not conducive to their mastery of welding knowledge and training of welding technology.
[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:
[0007] A simulated melting welding and thermal cutting device comprises an auxiliary stand with a simulated welder installed at the bottom, a welding operating table arranged on one side of the auxiliary stand, comprising a stand body and a touch screen all-in-one machine installed on the top of the stand body, a simulated welding and cutting gun group hung on the auxiliary stand, and four operable simulated gas meters, all of which are installed on the auxiliary stand; wherein, the simulated welding and cutting gun group comprises four simulated welding guns and one simulated cutting gun, and the above five simulated guns are all composed of a front touch head, a gun body and a button or knob, wherein the front touch head is installed at the front end of the gun body for sliding on the touch screen all-in-one machine to simulate the welding process.
[0008] Through the above-mentioned structural form, the simulated welding and cutting gun group includes four simulated welding guns and one simulated cutting gun.

[0012] Through the above-mentioned structural form, an electrical connection can be achieved between the analog welding machine and the touch screen all-in-one machine, and data transmission between the two can be realized.

In addition, an ID card reader is provided on the front side of the pedestal body.
[0016] Through the above-mentioned structural form, the set switch can be used to simulate the preparation operation before welding. In addition, the grounding operation can be simulated by the combination of the grounding simulation component and the grounding clamp. At the same time, the identity of the candidate can be identified by the ID card reader during the exam, which facilitates the binding of scores and identities.
[0017] In a possible implementation, a label reader is installed on the auxiliary stand, which is used to detect labels of labor protection products and hazard source labels.
[0018] Through the above-mentioned structural form, the tag reader can be used to judge whether the operator is wearing labor protection equipment and whether the dangerous source has been removed during welding, thereby playing a role in assessing whether the protection is done well during welding and whether there is a dangerous source.
[0019] In a possible implementation, the simulated welding and cutting gun group specifically includes five simulated guns: an arc welding gun, a carbon dioxide gas shielded welding gun, an argon arc welding gun, a gas welding gun, and a gas cutting gun.
[0020] Through the above-mentioned structural form, the equipment as a whole can be used to test a variety of different welding methods and operations.
[0021] In a possible implementation, the four operable simulated gas meters are a simulated carbon dioxide gas meter, a simulated argon gas meter, a simulated oxygen gas meter, and a simulated acetylene gas meter.
[0022] Through the above-mentioned structural form, different operable simulated gas meters can be adjusted corresponding to different welding methods, thereby making the assessment process more comprehensive and scientific.
[0023] In a possible implementation, the operable analog gas meter includes an analog meter body, an analog dial is provided on the analog meter body, and an adjustment knob is installed on the front end surface of the analog meter body.

[0034] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
[0035] Example 1, a simulated melting welding and thermal cutting device, including an auxiliary stand 1, a welding operating table 2, a simulated welding machine 3 and a simulated welding and cutting gun group 4, such as Figure 1 As shown, the main body of the welding operating table 2 is a base body 21, on which a touch screen all-in-one machine 22 and a switch group including a main switch 23, a ventilation switch 24, and a welding machine switch 25 are installed.
[0036] In this embodiment, the arc welding simulation gun in the simulation welding and cutting gun group 4 is used, and the corresponding arc welding simulation gun icon is selected on the software interface of the touch screen all-in-one machine 22 .
[0037] like Figure 2 As shown, the front end of the arc welding simulation welding gun is equipped with a front touch head. When the front operation is correct, simulated welding operations can be performed on the simulated welding board on the touch screen all-in-one machine 22.
[0038] The welding operation table 2 is equipped with a main switch 23 and a ventilation switch 24. When the switch is not turned on, the corresponding input port on the microcontroller is at a low level. When the switch is turned on, the corresponding input port on the microcontroller is at a high level.
[0039] The simulated welder 3 is equipped with a back-open / front-open switch and a current / voltage knob. When the switch is off, the corresponding input port on the microcontroller is low; when the switch is on, the corresponding input port on the microcontroller is high. The current / voltage knob is a potentiometer that corresponds to the analog ADC input port on the main control board. Rotating the potentiometer knob changes the voltage / current digital tube reading on the simulated welder 3. The grounding clamp 6 contains a reed sensor. When the grounding clamp 6 is successfully placed on the grounding simulation component 26, it outputs a high-level signal to the input port of the main control board. The software receives data from the main control board via serial communication to detect whether each switch and grounding are open and in what order. The software also detects any missing welds, leaking welds, or discontinuous solder joints during the welding process, which is then used to score the weld.
[0040] In addition, the ID card reader 27 can identify the identity of the examinee, making it easier to bind the score to the identity, and the tag reader 7 can determine whether the operator is wearing labor protection equipment and whether the dangerous source has been removed during welding.
[0041] Therefore, if Figure 3 As shown in the figure, during the assessment, the correct operating steps for arc welding are:
[0042] Power supply sequence: remove the danger source → turn on the main switch 23 → turn on the ventilation switch 24 → turn on the back switch → turn on the front switch → place the grounding clamp 6 on the grounding simulation component 26.
[0043] Power outage sequence: remove the grounding clamp 6 → turn off the front switch → turn off the back switch → turn off the ventilation switch 24 → turn off the main switch 23.
[0044] If the oil drum, which is a dangerous source, is operated in the test area, the entire test will be failed; the oil drum must be moved out of the test area before power supply operation.
[0045] Example 2 differs from Example 1 in that the simulated welding guns selected are different, namely a carbon dioxide gas shielded welding gun and an argon arc welding gun. When the button on the welding gun is not pressed, the input port of the microcontroller is a low-level signal. When the button is pressed, a high-level signal is output to the input port of the microcontroller.
[0046] In this example, after the grounding operation is completed, the corresponding operable analog gas meter 5 needs to be opened. The operable analog gas meter 5 corresponding to carbon dioxide / argon includes an analog meter body 501, and an analog dial 502 is provided on the analog meter body 501. The front face of the analog meter body 501 is installed with an adjustment knob 503. By rotating the adjustment knob 503, high and low level signals are output to the input port of the single-chip microcomputer. The software receives the data sent by the single-chip microcomputer through serial communication to detect whether the total opening, ventilation, back opening, front opening, grounding and the corresponding carbon dioxide / argon operable analog gas meter 5 are opened and the opening order. The software detects whether there are missing welds, leaking welds and discontinuous welds during the welding process, and scores them accordingly.
[0047] Therefore, if Figure 3 As shown, the correct operating steps during the assessment are:
[0048] Power supply sequence: remove the danger source → turn on the main switch 23 → turn on the ventilation switch 24 → turn on the back switch → turn on the front switch → place the grounding clamp 6 on the grounding simulation component 26 → turn on the corresponding operable simulation gas meter 5
[0049] Power outage sequence: turn off the corresponding operable analog gas meter 5 → remove the grounding clamp 6 → turn off the front switch → turn off the back switch → turn off the ventilation switch 24 → turn off the main switch 23.
[0050] Example 3 differs from Example 1 in that the simulated welding torch operates differently. The gas meter corresponding to the simulated welding / cutting torch operation is an acetylene and oxygen simulated gas meter 5, which is a switch knob. Rotating the knob outputs high and low level signals to the input port of the microcontroller. Software receives data from the microcontroller via serial communication to detect the master open, ventilation, and whether the corresponding acetylene and oxygen simulated gas meters are turned on, and in what order. The software also detects whether the welding flame is neutral and the welding results are scored accordingly.
[0051] In this example, the operation of the gas welding / gas cutting simulation welding gun is different from that of the gas shielded welding / argon arc welding simulation welding gun. The knob of the gas welding / gas cutting gun body is a potentiometer knob. By rotating the knob, an analog signal is output to the AD port of the microcontroller. The microcontroller outputs the corresponding data through AD signal conversion to the touch screen all-in-one machine 22. The software uses the data to change the flame size in the program.
[0052] The utility model adopts a touch screen all-in-one machine 22 and internal assessment software, which can detect each step of the trainee's use of simulated melting welding and thermal cutting equipment, and assist the trainee to quickly learn how to use the simulated welding gun. Due to the use of simulated welding operations, the effects of stable operation, high safety and repeated use can be achieved.
[0053] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
