When encountering metallic materials of different shapes, even if the existing equipment can fix them, the fixation is not firm enough, and shaking will occur during the test, resulting in inaccurate final test results. Furthermore, it cannot adjust the temperature of the metallic material according to the needs of the test, resulting in insufficient comprehensiveness of the test. Summary of the Invention

The multi-section electric push rod 301 is installed at the top center of the working frame 2. An installation opening is provided at the top center of the working frame 2. The adsorption electromagnetic block 302 is installed at the bottom of the multi-section electric push rod 301. The movable circular plate 311 is provided at the bottom of the adsorption electromagnetic block 302. The mounting block 304 is provided at the bottom of the movable circular plate 311. The impact head 305 is movably installed at the bottom of the mounting block 304. The weight-adding frame 303 is installed around the outside of the mounting block 304. A top cover is installed at the top of the weight-adding frame 303. A control panel is installed on one side of the working frame 2. The multi-section electric push rod 301 and the adsorption electromagnetic block 302 are electrically connected to the control panel. A fixed sleeve is installed on the outside of the adsorption electromagnetic block 302.

[0031] The impact mechanism 3 also includes a fixed circular plate 309, a working magnetic block 310, a mounting block 313, and a movable support rod 315. The fixed circular plate 309 is mounted on the bottom end of the mounting slide rod 306. The bottom end of the pull spring 308 is fixedly connected to the top end of the fixed circular plate 309. Connecting rods 9 are movably mounted on both sides of the movable circular plate 311, and the end of the connecting rod 9 away from the movable circular plate 311 is connected to one side of the movable circular plate 307. The mounting block 313 is mounted on the bottom end of the movable circular plate 311. The movable support rod 315 is movably mounted on the bottom end of the mounting block 313. The bottom end of the movable support rod 315 is connected to the top end of the mounting block 304. The working magnetic block 310 is installed inside the movable circular plate 311.

[0032] The impact mechanism 3 also includes a pressure control switch 312, a movable ball 314, a movable circular opening 316, a mounting docking block 317, and a mounting interface 318. The mounting block 313 has a movable circular opening 316 at its top, and a movable port is located at the bottom of the inner cavity of the movable circular opening 316. The top of the movable support rod 315 extends through the movable port and into the bottom of the inner cavity of the movable circular opening 316. The movable support rod 315 has a T-shaped cross-section, and several movable balls 314 are installed around the top of the movable support rod 315. When the movable support rod 315 moves, it drives the movable balls 314 to roll, reducing the friction of the movable support rod 315 during movement. A pressure control switch 312 is installed at the upper end of the inner cavity of 316. The pressure control switch 312 is electrically connected to the control panel. An installation interface 318 is opened at the bottom of the mounting block 304. An installation docking block 317 is installed at the top of the impact head 305. The front side of the inner cavity of the installation interface 318 has an unobstructed structure. A screw is installed between the two sides of the mounting block 304 and the installation docking block 317. The installation docking block 317 is connected to the inner cavity of the installation interface 318. When installing or replacing the impact head 305, the screw is turned to disassemble it. Then the installation docking block 317 is moved back and forth and forward to separate it from the inside of the installation interface 318.

[0033] The specific implementation method is as follows: When impacting, the impact head 305 is first moved to the upper end of the inner cavity of the working frame 2. During the movement, the adsorption electromagnetic block 302 is activated, causing the adsorption electromagnetic block 302 to generate magnetism. The multi-section electric push rod 301 is then activated to drive the adsorption electromagnetic block 302 downward, so that the adsorption electromagnetic block 302 contacts the top of the movable circular plate 311 and generates magnetic attraction with the working magnetic block 310 installed inside the movable circular plate 311. Then, the multi-section electric push rod 301 drives the adsorption electromagnetic block 302 and the movable circular plate 311 to move downward. 11 moves upward, causing the mounting block 313 and the movable support rod 315 to move upward. When the movable circular plate 311 moves upward, it causes the movable circular plate 307 to move upward, stretching the pull spring 308. The corresponding number of pull springs 308 can be installed according to usage requirements. During normal use, the pull springs 308 do not need to be installed. During impact testing, the power supply to the adsorption electromagnetic block 302 is disconnected, causing the working magnetic block 310 to lose its constraint. The pull spring 308 is then stretched by gravity. The force drives the impact head 305 downward, causing it to contact and impact the top of the fixed metal material. During normal use, the impact head 305 moves downward due to its own weight. During the impact, it pushes the movable support rod 315 upward, contacting and squeezing the pressure control switch 312. The pressure generated during the impact is fed back to the control panel. If the value fed back by the pressure control switch 312 is within the preset threshold range, it is considered qualified. If the value is outside the preset range, the number of pressure control switches 312 is set. When the number of qualified pressure control switches 312 reaches the preset number, the clamping stops moving, and the test end needs to be adjusted and retested. When changing to impact heads 305 of different sizes, the screw is rotated to separate from the mounting docking block 317, and then the mounting docking block 317 is moved to separate from the mounting interface 318, allowing the impact head 305 to be disassembled and replaced. It can also replace and install small, specially designed swing-arm impact devices. Example

[0034] Please see Figure 2 , Figure 3The present invention provides a technical solution: the limiting mechanism 4 further includes a movable slider 404, a movable groove 405, a movable screw 406, a mounting recess 408, and a single-phase motor 409. Movable grooves 405 are provided on both sides of the top of the worktable 1. The movable screw 406 is installed in the inner cavity of the movable groove 405 through bearings. Movable rods are installed through the worktable 1 at opposite ends of the two movable screws 406. Movable sliders 404 are movably installed at opposite ends of the two movable screws 406.

The top of the movable slider 404 is connected to the bottom of the movable plate 401.

[0035] The limiting mechanism 4 also includes a working airbag 403, a supporting airbag 407, a pushing spring 410, a mounting spring 411, and a movable top plate 415. The opposite ends of the limiting rods 402 on both sides have a T-shaped cross-section, and a mounting spring 411 is installed on the opposite end of each limiting rod 402. The end of the mounting spring 411 away from the limiting rod 402 is connected to one side of the movable plate 401. Working airbags 403 in a compressed state are installed on the bottom ends of both sides of the inner cavity of the working frame 2. A movable top plate 415 is installed on the end of each working airbag 403 away from the working frame 2. 15. The movable top plate 415 is equipped with compressed push springs 410 around the side of the movable top plate 415 near the working airbag 403. The end of the push spring 410 away from the movable top plate 415 is connected to the inner cavity of the working frame 2. The inner cavity of the movable top plate 415 is hollow. One-way valves are installed around the side of the movable top plate 415 away from the push spring 410. An air inlet is opened on the side of the movable top plate 415 relative to the one-way valve. A connection port is opened on the movable top plate 415 relative to the working airbag 403.

[0036] The limiting mechanism 4 also includes an installation port 412, a limiting electromagnetic block 413, a pressure touch switch 414, and a rubber top block 416. A collection recess 10 is provided at the center of the top of the worktable 1, and a compressed support airbag 407 is installed inside the collection recess 10. Air supply holes are provided at the bottom ends of both sides of the inner cavity of the work frame 2 and inside the worktable 1. The end of the air supply hole furthest from the working airbag 403 is connected to the bottom end of the support airbag 407 via a one-way air supply valve. The top of the support airbag 407... Several strip-shaped air strips are installed at equal intervals, and the expanded air strips pass through the gaps between the limiting top rods 402, effectively filling the gaps between the limiting top rods 402. An exhaust valve is installed on one side of the bottom of the supporting airbag 407, and several installation ports 412 are opened around the inner cavity of the movable passage. Each installation port 412 has a limiting electromagnetic block 413 installed inside. A rubber top block 416 is installed on the end of the limiting top rod 402 away from the pushing spring 410. The limiting top rod 402 is closer to... Each rubber top block 416 has a pressure touch switch 414 installed at one end. The limit rod 402 is covered with a rubber layer, and both ends of the rubber layer are sealed to the outside of the limit rod 402. Multiple vent holes are provided on the side of the limit rod 402 away from the rubber top block 416. A connecting hose is installed on the rear side of one end of the limit rod 402, opposite to the multiple vent holes. The end of the connecting hose away from the limit rod 402 is connected to the side of the working airbag 403. Due to the rubber layer... There is a gap between the limiting top rod 402 and the rubber layer. Air is supplied into the gap through multiple vent holes, causing the rubber layer to expand and contact the sample to be fixed, thus improving the wrapping effect during the limiting. Pulleys are installed on the front and rear sides of the bottom of both sides of the inner cavity of the working frame 2. Multiple pull ropes are installed on the opposite side of the two moving plates 401, and the multiple pull ropes are in a loose state. The end of the multiple pull ropes away from the moving plate 401 passes through the pulleys on the front and rear sides and is connected to the top and bottom of one side of the movable top plate 415 respectively.

[0037] The specific implementation method is as follows: When performing fixed testing on the metal material to be tested, the single-phase motor 409 is started to drive the left moving screw 406 to rotate first, and then drives the right moving screw 406 to rotate through the connecting rod 9. The threads on the outside of the two moving screws 406 are opposite in structure. When the two moving screws 406 rotate simultaneously, they will drive the two moving sliders 404 to move to the opposite side, drive the two moving plates 401 to move to the opposite side, and drive the two limiting rods 402 to move to the opposite side. This causes the rubber block 416 installed at one end of the limiting rod 402 to contact and press against the outside of the metal material to be tested. When the limiting rod 402 is blocked, while the moving plate 401 continues to move, the multi-strand pull rope is taut, and the push spring 410 is stretched. When the moving plate 401 and the limiting rod 402 move, the movable top plate 415 loses its restraint. The movable top plate 415 is pushed to move by the compressed mounting spring 411. The working airbag 403 is stretched, and gas is supplied to the working airbag 403 through the air inlet one-way valve. When the limiting rod 402 contacts and squeezes the outside of the metal material, it will contact and squeeze the pressure touch switch 414, and the pressure touch switch 414 will generate pressure value feedback to the control panel, so that the operator can intuitively feel the pressure when the limit is fixed. When the pressure when the compression is fixed does not reach the preset value, the movement compression is performed again. After the fixation is completed, the limiting electromagnetic block 413 is activated to generate magnetic attraction and limit the limiting rod 402. When the multi-strand pull rope is tightened and continues to move (since the multi-strand pull rope is initially in a loose state, it begins to tighten after moving a certain distance. When it continues to move, it drives the movable top plate 415 to move through the multi-strand pull rope), it will drive the movable top plate 415 to move away from the movable plate 401, so that the movable top plate 415 squeezes the working airbag 403. Gas is supplied to the inside of the support airbag 407 through the air outlet and the air supply one-way valve, causing the support airbag 407 to expand. Example

[0040] The specific implementation method is as follows: When testing metal materials at different temperatures, firstly, the multi-section electric telescopic rod 505 is activated to drive the mounting slider 510 to move towards the front of the inner cavity of the mounting slide rail 506. The moving frame plate 501 is then moved forward through the connecting pipe head, so that the working nozzle 502 moves to the upper end of the fixed metal material. Then, the control solenoid valve is activated to transport the refrigerant inside the storage tank 503 to the conveying trough 507 through the connecting pipe 504. Finally, the refrigerant is sprayed out through the working nozzle 502 and comes into contact with the metal material to lower its temperature. After the temperature drops, the multi-section electric telescopic rod 505 is activated again to drive the mounting slider 510 to reset. The moving frame plate 501 is then reset through the connecting pipe head. After resetting, the impact test is performed again.
