Description

Technical Field

[0001] This utility model relates to the field of metal processing device design technology, and more specifically, to a quenching and hardening treatment device for metal processing. Background Technology

[0002] Metal parts are materials with specific shapes, dimensions, and properties, formed from steel ingots, billets, or steel products through pressure processing. To facilitate subsequent use, metal parts undergo quenching and hardening. Quenching is a heat treatment process for steel that significantly improves the hardness, wear resistance, and fatigue strength of metal parts while retaining high internal toughness, thus greatly improving the physical properties of steel. Therefore, steel quenching is an essential step in many steel processing procedures. Existing quenching equipment uses shallow containers for quenching operations, which easily causes high-temperature liquid splashing during operation and makes it difficult to remove metal parts from the quenching tank after quenching, potentially leading to safety accidents. Therefore, a quenching and hardening treatment device for metal processing is proposed. Utility Model Content

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] See Figures 1 to 5 This utility model provides a quenching and hardening treatment device for metal processing, including a quenching frame 1, a top fixing frame 3, and a fixed mounting plate 6. A set of working supports 2 are respectively provided at the left and right ends of the panel of the quenching frame 1. The top fixing frame 3 is provided between the two sets of working supports 2. The bottom of the top fixing frame 3 is provided with a fixed mounting plate 6. A first part-removing frame 7 is provided at the left end of the fixed mounting plate 6, and a second part-removing frame 8 is provided at the right end of the fixed mounting plate 6. The inner cavity of the quenching frame 1 stores coolant as a quenching component, undertaking continuous or long-term quenching treatment of metal parts, effectively enhancing the overall hardening quality of the metal parts. The left and right ends of the quenching frame 1 are fixed to the two sets of working supports 2, establishing the installation of the top fixing frame 3. The bottom of the top fixing frame 3 is fixed to the fixed mounting plate 6. The two sets of part-removing frames are set on the fixed mounting plate 6, facilitating the alternating or synchronous removal of metal parts from the quenching tank 15 by the two sets of part-removing frames, or placing metal parts requiring quenching treatment into the quenching tank 15.

[0026] See Figure 4 A first hoisting motor 61 is located on the left edge of the fixed mounting plate 6, and a first lifting chain 62 is located on the output shaft of the first hoisting motor 61. A second hoisting motor 63 is located on the right edge of the fixed mounting plate 6, and a second lifting chain 64 is located on the output shaft of the second hoisting motor 63. A lifting filter screen is located at the bottom of the two sets of lifting chains. The fixed mounting plate 6 is located directly above the quenching tank 15. A lifting filter screen is installed inside the quenching tank 15. The two sets of hoisting motors can lower the two sets of lifting chains to reduce the height of the lifting filter screen and increase the effective depth of the quenching liquid inside the quenching tank 15, which facilitates the full quenching treatment of the metal parts. After the quenching treatment is completed, the two sets of hoisting motors rewind the corresponding lifting chains to pull the lifting filter screen out of the quenching liquid, so that the two sets of part pickers can take out the metal parts located on the lifting filter screen. Then, new metal parts are placed in for quenching treatment, so that the device can be used continuously and its processing efficiency can be improved.

[0027] See Figure 5The first pickup rack 7 includes a mounting frame 71. A connecting seat 72 is provided at the front end of the mounting frame 71. A first steering motor frame 73 is mounted on the connecting seat 72. A first steering shaft 74 is provided at the output end of the first steering motor frame 73. A second steering motor frame 75 is provided at the bottom of the first steering shaft 74. A second steering shaft 76 is provided at the output end of the second steering shaft 75. A third steering motor frame 77 is provided at the end of the second steering shaft 76. A connecting frame 78 is provided at the output end of the third steering motor frame 77. An electric mechanical claw 79 is provided at the bottom of the connecting frame 78. The first pickup rack 7 is connected to the fixed mounting plate 6 through the mounting frame 71. The mounting frame 71 establishes a connection with the first steering motor frame through the connecting seat 72. The first steering motor in the first steering motor frame 73 drives the entire picking frame to rotate circumferentially around the first steering axis 74, thereby adjusting the horizontal movement control of the mechanical claw. The second steering motor in the second steering motor frame 75 drives the component below it to rotate circumferentially around the second steering axis 76, thereby adjusting the vertical movement control of the mechanical claw. The movement adjustment of the picking component can be controlled by the first steering motor and the second steering motor. The rotation direction of the connecting frame 78 is controlled by the third steering motor in the third steering motor frame 77, thereby controlling the electric mechanical claw 79 to grab the oriented metal parts or to take out the quenched metal parts and send them out of the quenching device.

[0028] See Figure 1 The quenching frame 1 has a cold water tank 5 on the left side, a first water pump on the top of the cold water tank 5, and a coolant conduit 4 at the output end of the first water pump. The left end panel of the quenching frame 1 is fixed to the cold water tank 5. The cold water tank 5 continuously supplies cooling water to the quenching device. The first water pump draws cooling water and supplies it to the atomizing water nozzle through the coolant conduit 4.

[0029] The cold water tank 5 is equipped with a second water pump, and the output end of the second water pump is equipped with a water exchange pipe. The water exchange pipe is connected to the quenching tank 15. That is, the second water pump draws cooling water from the cold water tank 5 and inputs it into the quenching tank 15 through the water exchange pipe to replenish the quenching liquid in the quenching tank 15 and ensure the continuous operation of the quenching.

[0030] The top-mounted fixed frame 3 has a second filter screen at its bottom, and a DC fan is located below the second filter screen. The top-mounted fixed frame 3 also has a first filter screen at its bottom, and several atomizing water nozzles are located below the first filter screen. The top-mounted fixed frame 3 is configured as an airflow device through the two sets of filter screens. The DC fan is installed above the quenching tank 15, which is not completely sealed, to extract some of the leaked splash liquid. The highly atomized coolant sprayed from the atomizing nozzles can quickly reduce the temperature of the splash liquid, avoid safety accidents, and ensure the safety of the working environment.

[0031] See Figure 2The quenching frame 1 has a first mounting frame 11 at its rear end and a second mounting frame 12 at its front end. Each of the two mounting frames has a sliding limiting groove 13 on its inner side, with an anti-splash component 16 inside the sliding limiting groove 13. A quenching groove 15 is located in the center of the inner cavity of the quenching frame 1, and an inclined deposition frame 14 is located on the outer side of the quenching groove 15. The bottoms of the first mounting frame 11 and the second mounting frame 12 each have an independent sliding limiting groove 13. The inner cavities of the two mounting frames are designed to accommodate the anti-splash component 16, and the sliding limiting groove 13 is used to implement the anti-splash component 16. The extension and retraction limits of the first anti-splash baffle 161 and the second anti-splash baffle 162 ensure flexible control of the two sets of anti-splash baffles. During the quenching process, when the high-temperature metal parts come into contact with the quenching liquid, liquid splashing will occur. After the splashing liquid is intercepted by the two sets of anti-splash baffles, the splashing liquid drips onto the inclined deposition rack 14 or into the quenching tank 15. The inclined deposition rack 14 is set from the outside to the inside towards the quenching tank 15, which can conduct the deposited liquid into the quenching tank 15 for continued use. This can effectively avoid high-temperature liquid splashing and reduce safety hazards.

[0032] See Figure 3 The splash shield assembly 16 includes a first splash shield 161 and a second splash shield 162. Side supports 163 are respectively provided at the outer ends of the first splash shield 161 and the second splash shield 162. A first bidirectional cylinder 164 is provided between the two sets of side supports 163 at the left end of the first splash shield 161 and the second splash shield 162, and a second bidirectional cylinder 165 is provided between the two sets of side supports 163 at the right end of the first splash shield 161 and the second splash shield 162. The two sets of splash shields on the left... The two sets of anti-splash baffles are connected to the first bidirectional cylinder 164 through the side bracket 163 on their left side, and the two sets of anti-splash baffles are connected to the second bidirectional cylinder 165 through the side bracket 163 on their left side. The two sets of bidirectional cylinders are set in the inner cavity of the quenching machine frame. The same control command is input to the same side output end of the two sets of bidirectional cylinders, which can control the first anti-splash baffle 161 or the second anti-splash baffle 162 to extend and cover the top of the quenching tank 15, reduce the splashing of high temperature liquid, and ensure the safety of the working environment.

[0033] Due to the specifications of the two sets of mounting frames and the requirements for the lifting filter screen, the two sets of splash baffles are not in a closed state in the final relative state, providing space for the two sets of lifting chains. This also avoids the two sets of splash baffles being impacted by a large amount of water vapor generated during quenching, ensuring the safe use of the working components. This device can perform continuous deep quenching treatment on metal parts or perform alternating quenching and heating treatment on metal parts according to the specific quenching requirements. The picking and placing of metal parts are completed by the two sets of picking frames.

[0034] The second pick-up rack 8 has the same components and specifications as the first pick-up rack 7, and can perform synchronous pick-up, alternating pick-up and placement operations with the first pick-up rack 7, thereby improving the working efficiency of the pick-up device.

[0035] The present invention provides a quenching and hardening treatment device for metal processing. Upon opening the control terminal and initializing all components, the control terminal first controls two sets of pick-up racks to quickly place the heated metal parts onto a lifting filter screen floating above the quenching liquid surface. Two sets of hoisting motors lower the lifting filter screen, immersing the metal parts deep into the quenching tank 15. After the mechanical claw 79 completes the placement, it quickly retracts. The control terminal then controls the extension of two sets of anti-splash baffles. When the metal parts have completed the quenching process, the two sets of hoisting motors wind up two sets of lifting chains to pull the lifting filter screen out of the quenching liquid. The two sets of pick-up racks then remove the hardened metal parts. This process can be repeated.

[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
