[0014] A processing method for automated metal heat treatment equipment comprises the following steps: Step 1: When the metal needs to be heat treated, the output end of the hydraulic rod is controlled to move toward the bottom, the hook is controlled to clamp the metal, and the slide rail drives the hook to move toward the top of the quenching tank; Step 2: After moving to the top of the quenching pool, operate the output end of the hydraulic rod to move toward the quenching pool. The movement of the output end of the hydraulic rod will drive the spring piece to move. The movement of the spring piece will contact the friction plate and increase the resistance of the hydraulic rod when moving; Step 3: Slowly lower the output end of the hydraulic rod. The output end of the hydraulic rod will place the metal into the quenching pool to heat treat the metal and prevent the rapid contact between the metal and water from causing temperature gradients on the surface and inside of the metal workpiece, thereby generating residual stress, causing cracks and deformation, and causing damage. The present invention provides an automated metal heat treatment device and method thereof, which has the following beneficial effects: The invention drives the spring piece to move by the movement of the output end of the hydraulic rod. The movement of the spring piece will contact the friction plate and produce deformation. The deformation of the spring piece will increase the contact area with the friction plate, thereby increasing the resistance and slowing down the descent speed. Preventing the rapid contact between metal and water will cause a temperature gradient on the surface and inside of the metal workpiece, thereby generating residual stress, inducing cracks and deformation, and causing damage. When the ring moves to the bottom, it will push the limit block. The movement of the limit block will release the limit on the friction plate. The friction plate will drive itself away from the spring through the No. 1 spring reset, so that the output end of the hydraulic rod will no longer have a deceleration effect when moving to the top, preventing excessive friction from causing overload and damage to the hydraulic rod, thereby improving the protection of the device. When the output end of the hydraulic rod moves to the top, it will drive the push block to move, and the push block will drive the L-shaped rod to rotate. The rotation of the L-shaped rod will drive the friction plate to move and be limited by the limit plate again, which will not hinder the subsequent deceleration work, thereby improving the practicability of the device.

[0015] (2) The invention continuously takes in water from the water inlet and discharges it from the water outlet, so that the water in the quenching pool is always flowing, ensuring that the water in the quenching pool remains at a low temperature, preventing the water temperature from being too high and causing poor quenching effect, thereby improving production efficiency. When the slide rail slides to the top of the quenching pool, the sensing module in the sensor will detect the slide rail and start the control module. The control module will start the dual-axis motor, which will drive the threaded rod to rotate. The rotation of the threaded rod will drive the slide rod to move. The movement of the slide rod will drive the transmission rod to move. The movement of the transmission rod will drive the cover to move and seal the quenching pool to prevent the water from reacting violently after the metal comes into contact with the water, and the boiling water will splash and injure the workers, thereby improving production safety. When the cover moves, it will drive the steel cable to move. The movement of the steel cable will drive the water baffle to move. The movement of the water baffle will seal the water inlet and the water outlet to prevent the flowing water from increasing the generation of gas after coming into contact with the metal. Excessive gas will cause pores and bubbles to form inside the metal, affecting the density and strength of the material, thereby improving production efficiency.

[0016] (3) The invention provides a filter on the inner wall of the water outlet pipe so that the hot water after use can filter out the debris in the residue after being discharged, without hindering the recycling after cooling. The rotation of the threaded rod will drive the large shaft to rotate, and the rotation of the large shaft will drive the small shaft to rotate through the belt. The rotation of the small shaft will drive the rotating rod and the scraper to rotate. The scraper will scrape off the impurities on the surface of the filter to prevent the impurities from accumulating too much and causing the filtering effect to deteriorate, thereby improving the cleaning effect. When the scraper moves, it will contact the protrusion, and the scraper will vibrate after contacting the protrusion, thereby preventing the debris from adhering to the surface of the filter and improving the cleaning effect.

The support rod 66 is fixedly mounted on the inner wall of the outer shell 61, and the L-shaped plate 67 is rotatably mounted on the circumferential surface of the support rod 66. The ring 69 is fixedly mounted on the circumferential surface of the output end of the hydraulic rod 4, and the rotating plate 610 is fixedly mounted on the circumferential surface of the output end of the hydraulic rod 4. The push block 611 is rotatably mounted on the surface of the rotating plate 610, and the limit rod 612 is fixedly mounted on the circumferential surface of the output end of the hydraulic rod 4, which does not hinder the subsequent deceleration work and improves the practicality of the device.

[0021] A No. 1 spring 68 is provided between the friction plate 65 and the housing 61 , and the L-shaped plate 67 is in contact with the friction plate 65 , and the No. 1 spring 68 drives the friction plate 65 to reset.

[0022] The push block 611 contacts the L-shaped plate 67 , the limiting rod 612 contacts the push block 611 , and the limiting block 64 contacts the friction plate 65 .

[0023] A processing method for automated metal heat treatment equipment comprises the following steps: Step 1: When the metal needs to be heat treated, the output end of the hydraulic rod 4 is controlled to move toward the bottom, the hook 5 is controlled to clamp the metal, and the slide rail 3 drives the hook 5 to move toward the top of the quenching pool 71; Step 2: After moving to the top of the quenching pool 71, the output end of the hydraulic rod 4 is manipulated to move toward the quenching pool 71. The movement of the output end of the hydraulic rod 4 will drive the spring plate 62 to move. The movement of the spring plate 62 will contact the friction plate 65 and increase the resistance of the hydraulic rod 4 when moving; Step 3: Slowly lower the output end of the hydraulic rod 4, which will place the metal into the quenching pool 71 to perform heat treatment on the metal to prevent rapid contact between the metal and water, which will cause temperature gradients on the surface and inside of the metal workpiece, thereby generating residual stress, causing cracks and deformation, and causing damage.

[0024] When this embodiment is working: after the hook 5 clamps the metal, the slide rail 3 moves to drive the hook 5 to move to the top of the quenching pool 71, and then the output end of the hydraulic rod 4 puts the clamped metal into the water for quenching. When the output end of the hydraulic rod 4 moves, the movement of the output end of the hydraulic rod 4 will drive the spring piece 62 to move, and the movement of the spring piece 62 will contact the friction plate 65. After the spring piece 62 contacts the friction plate 65, it will be deformed. After the deformation of the spring piece 62, the contact area with the friction plate 65 will increase. The increase in the contact area will increase the friction between the spring piece 62 and the friction plate 65, so that the output end of the hydraulic rod 4 slowly descends when moving toward the quenching pool 71 to prevent the metal from contacting the water quickly, which will cause a temperature gradient on the surface and inside of the metal workpiece, thereby generating residual stress, inducing cracks and deformation, and causing damage. After the output end of the hydraulic rod 4 moves to the bottom, the movement of the output end of the hydraulic rod 4 will drive the ring 69 to move, and the movement of the ring 69 will contact and squeeze the limit block After the limit block 64 is squeezed, it will move toward the bottom. The movement of the limit block 64 will release the limit on the friction plate 65. After the friction plate 65 loses the limit, it will be reset by the No. 1 spring 68 to drive the friction plate 65 to move in the direction away from the hydraulic rod 4. After the movement, the friction plate 65 will no longer contact the spring 62, so that the output end of the hydraulic rod 4 will no longer have a deceleration effect when moving toward the top, preventing the hydraulic rod 4 from being overloaded and damaged due to excessive friction, thereby improving the protection of the device. When the output end of the hydraulic rod 4 moves toward the top, the movement of the output end of the hydraulic rod 4 will drive the rotating plate 610 to move, and the movement of the rotating plate 610 will drive the push block 611 to move. The push block 611 will contact the L-shaped plate 67 and drive the L-shaped plate 67 to rotate. The rotation of the L-shaped plate 67 will drive the friction plate 65 to move toward the output end of the hydraulic rod 4. The movement of the friction plate 65 will be re-limited by the limit block 64, which will not hinder the subsequent deceleration work, thereby improving the practicality of the device.
