Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically to a quenching equipment for metal heat treatment processing. Background Technology

[0002] Metal castings require quenching during production. This process involves heating the metal workpiece in a specific medium to a suitable temperature, holding it at that temperature for a certain time, and then cooling it at different rates in different media. The properties of the metal are controlled by altering its surface or internal microstructure. However, most existing quenching equipment simply places the quenching frame directly into the quenching tank for quenching.

[0003] Existing patent application CN202221929999.4 discloses a surface heat treatment quenching device for metal processing, relating to the field of metal quenching technology. This invention includes a quenching tank with channels on both side walls. A servo motor is fixedly mounted on the side wall of the quenching tank. The output end of the servo motor is fixedly connected to a rotating rod via a coupling. The output end of the rotating rod is fixedly connected to a gear via a coupling. A sliding rod is fixedly connected between the inner walls of the channels. A toothed plate is slidably connected to the outer surface of the sliding rod, meshing with the gear. A mounting bracket is fixedly mounted on the upper surface of the toothed plate, with one end extending out of the channel and slidably connected thereto. This invention solves the problem that existing quenching devices often directly place the quenching frame into the quenching tank for quenching. During quenching, it is difficult to move the quenching frame, causing it to quench in a fixed area, resulting in a poor quenching effect and affecting the quenching efficiency of the device.

[0004] The above-mentioned solution has the following problems during implementation: it is not convenient to quench multiple metals at the same time during use; in addition, the temperature of the quenching liquid rises after contacting hot metal, which makes it difficult to assist the quenching liquid in heat dissipation, resulting in an unsatisfactory quenching effect on subsequent metals. Therefore, a quenching device for metal heat treatment is needed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a quenching device for metal heat treatment, including a quenching pool 1. A water inlet / outlet valve pipe is installed at the bottom side of the quenching pool 1 for the inlet and outlet of quenching liquid. Straight grooves 101 are provided on both the left and right sides of the quenching pool 1. A rotating assembly 2 is provided inside the two straight grooves 101. A movable frame 3 is provided between the outer end of the rotating assembly 2 and the top of the quenching pool 1. A lifting assembly 4 is provided between the top and bottom of the movable frame 3. A pressing assembly 5 is provided on the side of the lifting assembly 4. A placement assembly 6 for placing multiple metal workpieces is provided at the bottom of the pressing assembly 5. A stirring assembly 7 is provided on the inner side of the quenching pool 1. A transmission assembly 8 for driving the stirring assembly 7 to stir is provided on the outer side of the quenching pool 1. After placing multiple metal workpieces on the top of the placement assembly 6, the pressing assembly 5 can simultaneously stir the multiple metal workpieces. When the time is fixed, the lifting component 4 drives the pressing component 5 and the placing component 6 to descend into the quenching liquid in the quenching tank 1, so that the quenching liquid submerges each metal workpiece. At this time, the rotating component 2 can drive the moving frame 3, the lifting component 4, the pressing component 5 and the placing component 6 to move back and forth in the quenching tank 1, so as to facilitate the simultaneous quenching treatment of multiple metal workpieces. Then, the transmission component 8 drives the stirring component 7 to stir and agitate the quenching liquid, so that the quenching liquid can be more evenly distributed on the surface of the metal workpieces, improving the quenching effect of multiple metal workpieces. At the same time, since the copper plate 702 in the stirring component 7 is in contact with the quenching liquid, part of the copper plate 702 is exposed outside the quenching liquid and part is in contact with the quenching liquid when rotating and stirring the quenching liquid. Therefore, it can help dissipate the heat of the quenching liquid after contacting the hot metal, so that the subsequent quenching effect of the metal is more ideal.

[0023] As one implementation method in this embodiment, such as Figure 1 and Figure 4As shown, the rotating assembly 2 includes a motor 201, which is fixedly installed on the outer side of the quenching tank 1. A screw 202 is installed at the output end of the motor 201. The screw 202 passes through the inside of the right straight groove 101, and the side end of the screw 202 is rotatably set inside the right straight groove 101. A guide rod 203 is fixedly connected between the inner ends of the left straight groove 101 and the outer end of the moving frame 3. One end of the moving frame 3 is threaded to the outer end of the screw 202, and the other end of the moving frame 3 is sleeved on the outer end of the guide rod 203. In practice, multiple metal workpieces are placed... After the top of the placement component 6 is placed, multiple metal workpieces can be fixed simultaneously by the pressing component 5. At this time, the lifting component 4 drives the pressing component 5 and the placement component 6 to descend into the quenching liquid in the quenching pool 1, so that the quenching liquid submerges each metal workpiece. At this time, the starting motor 201 can drive the screw 202 to rotate. At this time, due to the limiting of the guide rod 203 on the moving frame 3, the moving frame 3 can move back and forth when the screw 202 rotates. At this time, the moving frame 3 can drive each metal workpiece to move back and forth in the quenching liquid, thus facilitating the simultaneous quenching treatment of multiple metal workpieces.

[0024] As one implementation method in this embodiment, such as Figure 1 and Figure 2As shown, the lifting assembly 4 includes a mounting box 401, which is fixedly connected to the middle of the movable frame 3. A second motor 402 is fixedly connected to the top of the mounting box 401. A second screw 403 is installed at the output end of the second motor 402. The second screw 403 passes through the interior of the mounting box 401, and the bottom end of the second screw 403 is rotatably located at the bottom of the interior of the mounting box 401. The pressing assembly 5 includes a screw sleeve 501, which is threadedly connected to the outer end of the second screw 403. The side end of the screw sleeve 501 is fixed. A top plate 502 is connected to the top of the top plate 502, and a cylinder 503 is installed at the top of the top plate 502. The telescopic end of the cylinder 503 extends to the bottom of the top plate 502, and a pressure plate 504 is installed at the telescopic end of the cylinder 503. The placement component 6 includes two vertical plates 601, both of which are fixedly connected to the bottom of the top plate 502. A support platform 602 is fixedly connected between the bottom ends of the two vertical plates 601. A baffle 603 is fixedly connected to the top of the support platform 602, and several spaced-apart components are fixedly connected to the top of the support platform 602. The top of the partition plate 604 and the support platform 602 has several slots 605 extending downwards. The slots 605 facilitate contact between the quenching liquid and the metal workpiece. In practice, each metal workpiece requiring quenching is placed on the top of the support platform 602. The baffle 603 shields each workpiece, facilitating placement. The partition plate 604 separates each workpiece for easier quenching. The cylinder 503 then moves the pressure plate 504 downwards, thus... Plate 504 can contact the top of the metal workpiece and press each metal workpiece downward to fix it. At this time, the starting motor 402 drives the screw 403 to rotate. Due to the limiting of the screw sleeve 501 by the top plate 502, the screw sleeve 501 can move down along the outer end of the screw 403. After the screw sleeve 501 and the top plate 502 move down, they can drive the support 602 and each metal workpiece at the top to move down until all the metal workpieces are submerged in the quenching liquid. At this time, it is convenient to quench multiple metal workpieces at the same time.

[0025] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the agitation assembly 7 includes two rotating rods 701, both rotatably positioned between the outer and inner ends of the quenching tank 1. The two rotating rods 701 are spaced apart, and several copper plates 702 are fixedly connected to the outer end of each rotating rod 701. A bracket 703 is fixedly connected to the outer end of the quenching tank 1, and a motor 704 is fixedly mounted on the top of the bracket 703. The output end of the motor 704 is connected to one of the rotating rods 701. The transmission assembly 8 includes two sprockets 801, each fixedly connected to the outer end of each rotating rod 701. A chain 802 is sleeved between the outer ends of the two sprockets 801. In practice, starting the motor 704 drives one of the rotating rods 701 to rotate. Since both rotating rods 701 are fixedly connected to sprockets 801 at their outer ends, and a chain 802 is sleeved between the outer ends of the two sets of sprockets 801, the other rotating rod 701 can rotate together when one rotating rod 701 rotates. At this time, the two sets of rotating rods 701 can drive the several copper plates 702 fixed at their outer ends to stir and move the quenching liquid, so that the quenching liquid can be more evenly distributed on the surface of the metal workpiece, improving the quenching effect on multiple metal workpieces. At the same time, since the copper plates 702 are in contact with the quenching liquid, part of the copper plates 702 are exposed outside the quenching liquid and part are in contact with the quenching liquid when rotating and stirring the quenching liquid. Therefore, it can help dissipate heat from the quenching liquid that has increased in temperature after contacting hot metal, making the subsequent quenching effect of the metal more ideal.

[0026] Working Principle: Each metal workpiece requiring quenching is placed on top of the support 602. The baffle 603 shields each workpiece, facilitating placement. The partition plate 604 separates the workpieces for easier quenching. The starting cylinder 503 moves the pressure plate 504 downwards, contacting the top of each workpiece and pressing it down. The starting motor 402 rotates the screw 403. Due to the limiting effect of the top plate 502 on the screw sleeve 501, the sleeve moves downwards along the outer end of the screw 403. This downward movement of the sleeve and top plate 502 moves the support 602 and each metal workpiece at the top until they are all submerged in the quenching liquid. The starting motor 201 then rotates the screw 202. Due to the limiting effect of the guide rod 203 on the moving frame 3, the screw 202 moves downwards as it rotates. The movable frame 3 can move back and forth, allowing each metal workpiece to move back and forth in the quenching liquid. This facilitates the simultaneous quenching of multiple metal workpieces. By starting the motor 704, one of the rotating rods 701 is driven to rotate. Since both rotating rods 701 are fixedly connected to sprockets 801 at their outer ends, and a chain 802 is sleeved between the outer ends of the two sets of sprockets 801, the other rotating rod 701 can rotate together after one rotating rod 701 rotates. At this time, the two sets of rotating rods 701 can drive several copper plates 702 fixed at their outer ends to stir and agitate the quenching liquid, so that the quenching liquid can be more evenly distributed on the surface of the metal workpieces, improving the quenching effect on multiple metal workpieces. At the same time, since the copper plates 702 are in contact with the quenching liquid, part of the copper plates 702 are exposed outside the quenching liquid while part of them are in contact with the quenching liquid when rotating and stirring the quenching liquid. Therefore, it can help dissipate heat from the quenching liquid that has increased in temperature after contacting hot metal, making the subsequent quenching effect of the metal more ideal.
