Description

Technical Field

[0001] This invention belongs to the field of metal heat treatment technology, specifically a feeding device for a quenching tank for metal parts. Background Technology

[0002] Currently, quenching is a common heat treatment method for metals, which can improve the strength and hardness of metals.

[0003] In existing technologies, when quenching metal parts, it is usually necessary to place the metal parts to be quenched into the quenching tank, immersing them in the quenching medium inside the tank. After quenching, the metal parts need to be removed from the quenching tank. However, since the metal parts have undergone calcination heating before quenching, impurities inside the metal parts are squeezed to the surface of the parts during the calcination process. These impurities come into contact with air and form oxide scale. As a result, when the parts are subsequently quenched in the quenching medium, the oxide scale is easy to detach from the surface of the parts and remain inside the quenching medium. Excessive oxide scale residue in the quenching medium will affect the quenching effect and quenching quality of the parts. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a feeding device for a quenching tank for metal parts.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A feeding device for a quenching tank for metal parts includes a holding cylinder, a drive assembly, a lifting assembly, and a scooping net.

[0007] The holding cylinder is positioned above the quenching tank and its vertical movement is controlled by the lifting assembly. When the holding cylinder moves downward, it brings the parts to be quenched into the quenching tank; when the holding cylinder moves upward, it brings the quenched parts out of the quenching tank.

[0008] The net is positioned inside the holding tube, and the drive assembly is installed inside the holding tube.

[0009] As the net moves downwards along with the container, the drive assembly is used to retract the net.

[0010] As the scooping net moves upward along with the container, the driving assembly is used to drive the scooping net into an unfolded state to scoop up the oxide scale impurities floating on the surface of the quenching medium.

[0011] As a further improvement of the present invention: the container includes a cylinder body, a container net is provided at the bottom of the cylinder body, and an opening for taking out and putting in is provided on the side wall of the cylinder body.

[0012] As a further improvement of the present invention: a central block is provided at the center of the inner side of the cylinder, and the central block is fixedly connected to the inner wall of the cylinder by a plurality of connecting rods.

[0013] A storage strip is fixedly installed on the inner wall of the cylinder. The storage strip is hollow inside and distributed radially along the cylinder. A scroll is rotatably installed inside the storage strip, and a slot is formed on the side wall of the storage strip.

[0014] The drive assembly includes a motor and a rotating shaft controlled by the motor. The rotating shaft is distributed along the axis of the cylinder. A traction rod is fixedly installed on the side wall of the rotating shaft. The traction rod is distributed radially along the cylinder. One end of the net is wound around the outside of the reel, and the other end extends from the slot to the outside of the receiving strip and is connected to the traction rod.

[0015] As a further improvement of the present invention: a coil spring for applying rotational force to the scroll is installed inside the storage strip.

[0016] As a further improvement of the present invention: a partition mesh plate is hinged inside the pick-up and put-out port.

[0017] As a further improvement to the present invention: the lifting assembly includes a lifting rope and a lifting plate.

[0018] The lifting plate is located at the center of the cylinder. The motor is fixedly installed on the upper part of the lifting plate. One end of the rotating shaft is connected to the output end of the motor, and the other end passes through the lifting plate and is rotatably connected to the center block. One end of the lifting rope is connected to the lifting plate, and the other end is connected to an external rope winder.

[0019] As a further improvement of the present invention: the external rope reel includes a drive motor and a reel that is controlled to rotate by the drive motor, and the end of the lifting rope away from the lifting plate is connected to the reel.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In this embodiment of the invention, initially, the holding cylinder is located above the quenching tank. When quenching is required, the part to be quenched can be placed inside the holding cylinder. Then, the lifting assembly moves the holding cylinder downwards, bringing the part inside into the quenching tank. After entering the quenching tank, the part is immersed in the quenching medium, thus completing the quenching process. After the part is quenched, the lifting assembly moves the holding cylinder and the part inside it upwards, bringing the part out of the quenching tank. Then, the part inside the holding cylinder can be removed. During the downward movement of the holding cylinder, the state of the scooping net is controlled by the driving assembly, so that the scooping net is in a retracted state inside the holding cylinder. When the part is immersed in the quenching medium, the scooping net is also in a retracted state and immersed in the quenching medium, with the scooping net positioned above the part. During the quenching process, the oxide scale and impurities attached to the surface of the part detach from the surface and then move along the quenching medium. The oxide scale impurities rise from the quenching medium to the surface. At this point, the retracted scoop does not intercept the rising oxide scale impurities. After the part is quenched, the drive assembly controls the state of the scoop, causing it to unfold inside the holding cylinder. Subsequently, the lifting assembly moves the holding cylinder and the part upward together. As the holding cylinder moves upward, the unfolded scoop moves along the inside of the quenching medium, thereby picking up the oxide scale impurities floating on the surface of the quenching medium. In this way, when the holding cylinder takes the part out of the quenching tank, the unfolded scoop can carry away the oxide scale impurities remaining in the quenching medium, thus preventing oxide scale impurities from remaining in the quenching medium and improving the subsequent quenching effect of the quenching medium on the part. Compared with the existing technology, when quenching parts, it can automatically pick up the oxide scale impurities that peel off from the surface of the part into the quenching medium, thereby preventing dust and debris from remaining inside the quenching medium and affecting the subsequent quenching effect of the part.

Detailed Implementation

[0027] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Please see Figure 1 as well as Figure 2 This embodiment provides a feeding device for a quenching tank of metal parts, including a holding cylinder 20, a driving assembly 30, a lifting assembly 40, and a scooping net 50. The holding cylinder 20 is disposed above the quenching tank 10 and is controlled to move up and down by the lifting assembly 40. When the holding cylinder 20 moves down, it brings the parts to be quenched into the quenching tank 10. When the holding cylinder 20 moves up, it brings the quenched parts out of the quenching tank 10. The scooping net 50 is movably disposed inside the holding cylinder 20. The driving assembly 30 is installed inside the holding cylinder 20. When the scooping net 50 moves down with the holding cylinder 20, the driving assembly 30 drives the scooping net 50 to a retracted state. When the scooping net 50 moves up with the holding cylinder 20, the driving assembly 30 drives the scooping net 50 to an unfolded state to scoop up oxide scale impurities floating on the surface of the quenching medium.

[0030] Initially, the holding cylinder 20 is positioned above the quenching pool 10. When quenching is required, the part to be quenched can be placed inside the holding cylinder 20. Then, the lifting assembly 40 moves the holding cylinder 20 downwards, bringing the part inside into the quenching pool 10. Once inside, the part is immersed in the quenching medium, completing the quenching process. After quenching, the lifting assembly 40 moves the holding cylinder 20 and the part inside it upwards, removing the part from the quenching pool 10. The part can then be removed from the holding cylinder 20. During the downward movement of the holding cylinder 20, the drive assembly 30 controls the state of the retrieval net 50, ensuring it is retracted inside the holding cylinder 20. When the part is immersed in the quenching medium, the retracted net 50 is also immersed in the quenching medium. At the position above the part, during the quenching process, the oxide scale impurities attached to the surface of the part detach from the surface and float up to the surface of the quenching medium. At this time, the scoop net 50, which is in a retracted state, does not intercept the floating oxide scale impurities. After the part is quenched, the drive component 30 controls the state of the scoop net 50, causing the scoop net 50 to unfold inside the holding cylinder 20. Then, the lifting component 40 moves the holding cylinder 20 and the part upward together. When the holding cylinder 20 moves upward, the unfolded scoop net 50 moves upward along the inside of the quenching medium, thereby picking up the oxide scale impurities floating on the surface of the quenching medium. In this way, when the holding cylinder 20 takes the part out of the quenching pool 10, the unfolded scoop net 50 can take out the oxide scale impurities remaining in the quenching medium, thereby preventing oxide scale impurities from remaining in the quenching medium and improving the subsequent quenching effect of the quenching medium on the part.

[0031] Please see Figure 1 In one embodiment, the holding cylinder 20 includes a cylinder body 201, a holding net 202 is provided at the bottom of the cylinder body 201, and a take-out port 203 is provided on the side wall of the cylinder body 201.

[0032] By placing the part to be quenched into the inner side of the cylinder 201 through the self-receiving port 203, the part is placed on the upper part of the holding net 202. When the lifting component 40 moves the cylinder 201 down into the quenching pool 10, the quenching medium can enter the cylinder 201 through the holding net 202 and the self-receiving port 203, thereby performing quenching treatment on the part. After quenching is completed, as the lifting component 40 brings the cylinder 201 and the part out to the top of the quenching pool 10, the operator can take the part out from the inside of the cylinder 201 through the self-receiving port 203.

[0033] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4In one embodiment, a center block 205 is provided at the center of the inner side of the cylindrical body 201. The center block 205 is fixedly connected to the inner wall of the cylindrical body 201 by a plurality of connecting rods 204. A storage strip 206 is fixedly provided on the inner wall of the cylindrical body 201. The storage strip 206 is hollow inside and is radially distributed along the cylindrical body 201. A scroll 207 is rotatably provided inside the storage strip 206. A slot is provided on the side wall of the storage strip 206 (Figure). (Not shown in the image), the drive assembly 30 includes a motor 301 and a rotating shaft 302 controlled by the motor 301. The rotating shaft 302 is distributed along the axis of the cylinder 201. A traction rod 303 is fixedly installed on the side wall of the rotating shaft 302. The traction rod 303 is distributed radially along the cylinder 301. One end of the net 50 is wound around the outside of the reel 207, and the other end extends from the slot to the outside of the receiving strip 206 and is connected to the traction rod 303.

[0034] When the part is in the quenching medium for quenching, the traction rod 303 is located on one side of the receiving bar 206, and the scoop net 50 is wound around the outside of the reel 207. At this time, the scoop net 50 is in the retracted state in the quenching medium. After the part is quenched, the motor 301 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the traction rod 303 to rotate. When the traction rod 303 rotates, it moves away from the receiving bar 206 and pulls the scoop net 50, so that the scoop net 50 is unwound from the outside of the reel 207. When the traction rod 303 rotates from one side of the receiving bar 206 to the other side, the scoop net 207 is unwound and unfolded. At this time, the scoop net 50 has a ring structure inside the cylinder 201. Then, as the lifting component 40 moves the cylinder 201 and the part upward, the ring-shaped scoop net 50 moves upward along the inside of the quenching medium, thereby picking up the oxide scale impurities floating on the surface of the quenching medium.

[0035] In one embodiment, a coil spring is installed inside the receiving strip 206 to apply rotational force to the reel 207. When the motor 301 drives the traction rod 303 to rotate via the rotating shaft 302, thereby driving the net 50 to unwind from the reel 207, the reel 207 rotates accordingly, and the coil spring is stressed. After the cylinder 201 and parts are brought out from the quenching tank 10, the workers can clean the oxide scale and impurities on the net 50. Then, the motor 301 drives the rotating shaft 302 to rotate in the opposite direction, and the rotating shaft 302 drives the traction strip 303 to rotate in the opposite direction. When the traction strip 303 rotates in the opposite direction, the coil spring drives the reel 207 to rotate in the opposite direction inside the receiving strip 206, thereby winding up the net 50 and keeping the net 50 in the wound state again.

[0036] During the quenching process, some dust and debris peeling off from the part surface can easily move out through the pick-and-place port 203 and float up into the quenching medium outside the cylinder 201, eventually settling on the surface of the quenching medium outside the cylinder 201. At this point, the unfolded scooping net 50 cannot effectively remove this oxide scale impurity. Therefore, in one embodiment, a baffle plate (not shown in the figure) is hinged inside the pick-and-place port 203. When the worker places the part to be quenched from the pick-and-place port 203 onto the holding net 20... 2. The upper part can be closed with a baffle plate. In this way, when the part is subsequently immersed in the quenching medium for quenching treatment, the oxide scale impurities peeled off from the surface of the part will not be moved out of the pick-up and put-out port 203 to the outside of the cylinder 201 due to the obstruction of the baffle plate. As a result, they will not float on the surface of the quenching medium on the outside of the cylinder 201, but will float up along the quenching medium inside the cylinder 201 and float on the surface of the quenching medium inside the cylinder 201. Therefore, the unfolded scooping net 50 can effectively scoop up the oxide scale impurities when it moves upward in the subsequent process.

[0037] Please see Figure 1 as well as Figure 2 In one embodiment, the lifting assembly 40 includes a lifting rope 401 and a lifting plate 402. The lifting plate 402 is located at the center above the cylinder 201. The motor 301 is fixedly installed on the upper part of the lifting plate 402. One end of the rotating shaft 302 is connected to the output end of the motor 301, and the other end passes through the lifting plate 402 and is rotatably connected to the center block 205. One end of the lifting rope 401 is connected to the lifting plate 402, and the other end is connected to an external rope winder (not shown in the figure).

[0038] The lifting rope 401 is wound and unwound by an external rope winder. When the lifting rope 401 is unwound, the lifting plate 402, motor 301, rotating shaft 302, center block 205, connecting rod 204, cylinder 201 and holding net 202 move downward under the action of gravity. The parts to be quenched on the upper part of the cylinder 201 and holding net 202 enter the quenching pool 10. When the lifting rope 401 is wound up, the lifting rope 401 pulls the lifting plate 402, which in turn drives the motor 301, rotating shaft 302, center block 205, connecting rod 204, cylinder 201 and holding net 202 to move upward. The holding net 202 brings the quenched parts out of the quenching pool 10.

[0039] In one embodiment, the external rope winder includes a drive motor and a reel controlled by the drive motor. The end of the lifting rope 401 away from the lifting plate 402 is connected to the reel. The drive motor drives the reel to rotate in both directions, thereby winding and unwinding the lifting rope 401. When the lifting rope 401 is wound and unwinded, the cylinder 201 and the parts are moved up and down.

[0040] In this embodiment of the invention, initially, the holding cylinder 20 is located above the quenching tank 10. When quenching is required, the part to be quenched can be placed inside the holding cylinder 20. Subsequently, the lifting assembly 40 moves the holding cylinder 20 downward, and as the holding cylinder 20 moves downward, it carries the part inside into the quenching tank 10. After entering the quenching tank 10, the part is immersed in the quenching medium, thereby completing the quenching process. After the part is quenched, the lifting assembly 40 moves the holding cylinder 20 and the part inside the holding cylinder 20 upward together. The parts are moved, thus bringing them out of the quenching tank 10. Then, the parts inside the holding cylinder 20 are removed. During the downward movement of the holding cylinder 20, the state of the scooping net 50 is controlled by the drive assembly 30, so that the scooping net 50 is in a retracted state inside the holding cylinder 20. When the parts are immersed in the quenching medium, the scooping net 50 is also retracted and immersed in the quenching medium, with the scooping net 50 positioned above the parts. During the quenching process, oxide scale impurities adhering to the surface of the parts are removed from the surface. The part detaches and then floats up to the surface of the quenching medium. At this point, the retracted scoop net 50 does not intercept the floating oxide scale impurities. After the part is quenched, the drive assembly 30 controls the state of the scoop net 50, causing it to unfold inside the holding cylinder 20. Then, the lifting assembly 40 moves the holding cylinder 20 and the part upwards together. As the holding cylinder 20 moves upwards, the unfolded scoop net 50 moves upwards along the quenching medium, thereby scooping up the oxide scale impurities floating on the surface of the quenching medium. When the holding cylinder 20 carries the parts out of the quenching tank 10, the unfolded scooping net 50 can carry away the oxide scale impurities remaining in the quenching medium, thereby preventing oxide scale impurities from remaining in the quenching medium and improving the subsequent quenching effect of the quenching medium on the parts. Compared with the prior art, when quenching parts, the oxide scale impurities peeled from the surface of the parts into the quenching medium can be automatically retrieved, thereby preventing dust and debris from remaining in the quenching medium and affecting the subsequent quenching effect of the parts.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
