Description

Technical Field

[0001] This utility model relates to the field of heat treatment processing of metal parts, and in particular to a cooling device for heat treatment processing of metal parts. Background Technology

[0002] An existing patent (publication number: CN221626317U) discloses a cooling device for heat treatment of metal parts, comprising: a housing, a drive mechanism mounted on the bottom of the housing, the output end of the drive mechanism being connected to a rotating shaft via the bottom of a cooling box, the cooling box being disposed inside the housing, an axisymmetric first sliding block and an axisymmetric second sliding block slidably mounted on the upper side of the housing, a primary sliding wheel and a secondary sliding wheel fixedly mounted on the upper part of the two axisymmetric first sliding blocks, a first connecting rod and a second connecting rod mounted on the upper part of the two axisymmetric second sliding blocks, an upper cooling nozzle mounted on the lower part of the first connecting rod and the second connecting rod, and a rotating baffle mounted on the upper part of the rotating shaft. However, this device places the metal parts in the cooling box when cooling them, and this structure requires the metal parts to be removed one by one after cooling is completed, making it impossible to repeatedly cool multiple metal parts. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a cooling device for heat treatment of metal parts that can continuously cool metal tubes on rotating plates at different positions and allows manual replacement of the cooled metal tubes.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A cooling device for heat treatment of metal parts includes a cooling box, a support frame plate, a rotating ring plate, a strip connecting plate, a rotating disk, a hanging rod, a rotating hanging plate, a rotating pressure rod, and a motor. The cooling box has an upper opening and contains coolant. The support frame plate has a set of side plates on its side, which are connected to the cooling box. A first shaft passes through the support frame plate and connects to a limiting side column, rotating within the support frame plate. The side of the connecting column is in contact with the strip connecting plate, which is connected to the rotating ring plate. The first shaft is adapted to the connecting column and passes through it, connecting to the strip connecting plate and the connecting column. The side of the connecting column is connected to the rotating pressure rod. The support frame plate has a motor mounting plate on its side, which is bolted to the side of the motor.

[0006] The motor shaft is connected to the limiting side column. The side of the rotating ring plate has an opening. The side of the rotating disk is connected to the lifting rod. Multiple lifting rods are evenly distributed on the side of the rotating disk. The lifting rods are inserted into the opening of the ring plate. The outer side of the rotating ring plate is in contact with the lifting rods. The lower surface of the rotating pressure rod is in contact with the lifting rods.

[0007] The side of the boom has a set of boom protrusions, the upper part of the rotating hanging plate has a hanging plate groove, the boom is adapted to the hanging plate groove, the boom is inserted into the hanging plate groove, the front and rear sides of the rotating hanging plate are in contact with a set of boom protrusions, the lower part of the rotating hanging plate has a hanging plate lower groove, and the hanging plate lower groove is symmetrically arranged on both sides of the rotating hanging plate. Beneficial effects

[0008] 1. The lower side of the support frame plate of this utility model is connected to the cooling box body through a set of frame plate side plates, so that the entire device is installed on the cooling box body. The rotating ring plate is connected to the strip connecting plate. The circular support platform is connected to the connecting column and the strip connecting plate in sequence. The motor is installed and fixed on the motor mounting plate. The motor shaft is connected to the limiting side column. When the motor works, it drives the first shaft to rotate, thereby controlling the rotating ring plate to rotate. The rotating pressure rod is installed and fixed on the connecting column. The rotating ring plate and the rotating pressure rod rotate simultaneously. The circular support platform limits the rotation of the rotating plate. The surface is in contact with the rotating disk. The second shaft passes through the rotating disk and connects to the anti-detachment disc. The anti-detachment disc prevents the rotating disk from slipping off the second shaft during the cooling process of the metal part during heat treatment. The second shaft supports the rotating disk and ensures the axial position of the rotating disk. When the rotating pressure rod rotates to a certain angle, it is in contact with the hanging rod. When the rotating pressure rod continues to rotate, it presses the hanging rod downward, causing the rotating disk to rotate. When the hanging rod is disconnected from the rotating pressure rod, the next hanging rod in sequence enters the rotating ring plate from the ring plate opening. The rotating ring plate rotates so that a hanging rod is placed inside the rotating ring plate.

[0009] 2. In this utility model, two adjacent hanging rods are in contact with the outer side of the rotating ring plate. The time it takes for the rotating pressure rod to rotate one revolution after being disconnected from the hanging rod is the time it takes for the rotating disk to stop rotating. The hanging rod is inserted into the groove of the hanging plate, so that the upper part of the rotating hanging plate is hung on the hanging rod. A set of hanging rod protrusions prevents the rotating hanging plate from slipping off the hanging rod during the cooling process of metal parts heat treatment. A set of hanging plate grooves at the bottom of the rotating hanging plate contains metal tubes. When the rotating disk rotates, the rotating hanging plates hanging on different hanging rods enter the cooling box in sequence to perform a cooling operation. The cooling time of each set of metal tubes in the cooling box is exactly the time it takes for the rotating pressure rod to rotate one revolution. This device can continuously cool the metal tubes on the rotating hanging plates at different positions. The metal tubes that are rotated out after cooling can be replaced manually.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0017] Example 1:

[0018] A cooling device for heat treatment of metal parts includes a cooling box 01, a support frame plate 03, a rotating ring plate 09, a strip connecting plate 11, a rotating disk 13, a hanging rod 14, a rotating hanging plate 16, a rotating pressure rod 19, and a motor 20. The cooling box 01 has an upper opening 02 at its upper part and contains coolant inside. The support frame plate 03 has a set of frame side plates 04 on its side, which are connected to the cooling box 01. The lower side of the support frame plate 03 is connected to the cooling box 01 through the set of frame side plates 04, so that the entire device is mounted on the cooling box 01. A first shaft 06 passes through the support frame plate 03 and is connected to the cooling box 01. The first shaft 06 rotates within the support frame plate 03, and the side of the connecting column 12 is in contact with the strip connecting plate 11. The strip connecting plate 11 is connected to the rotating ring plate 09. The first shaft 06 is adapted to the connecting column 12 and passes through the connecting column 12 to connect to the strip connecting plate 11. The first shaft 06 is connected to the connecting column 12. The side of the connecting column 12 is connected to the rotating pressure rod 19, which is installed and fixed on the connecting column 12. The rotating ring plate 09 and the rotating pressure rod 19 rotate simultaneously. The side of the support frame plate 03 has a motor mounting plate 05, and the side of the motor 20 is bolted to the motor mounting plate 05.

[0019] Example 2:

[0020] The motor 20 described in this invention has its rotating shaft connected to the limiting side column 21. The motor 20 is mounted and fixed on the motor mounting plate 05. The rotating shaft of the motor 20 is connected to the second shaft 08. The operation of the motor 20 drives the first shaft 06 to rotate, thereby controlling the rotating ring plate 09 to rotate. The rotating ring plate 09 has a ring plate opening 10 on its side. The rotating disk 13 is connected to the side of the hanging rod 14. Multiple hanging rods 14 are evenly distributed on the side of the rotating disk 13. The hanging rods 14 are inserted into the ring plate opening 10. The outer side of the rotating ring plate 09 is in contact with the hanging rod 14. The lower surface of the rotating pressure rod 19 is in contact with the hanging rod 14. When the dynamic pressure rod 19 rotates to a certain angle, it is in contact with the lifting rod 14. When the rotating pressure rod 19 continues to rotate, it presses the lifting rod 14 downward, causing the rotating disk 13 to rotate. When the lifting rod 14 is disconnected from the rotating pressure rod 19, the next lifting rod 14 enters the rotating ring plate 09 from the ring plate opening 10. The rotating ring plate 09 rotates so that one lifting rod 14 is placed inside the rotating ring plate 09, and the two adjacent lifting rods 14 are in contact with the outer side of the rotating ring plate 09. The time it takes for the rotating pressure rod 19 to rotate one revolution after being disconnected from the lifting rod 14 is the time it takes for the rotating disk 13 to stop rotating.

[0021] Example 3:

[0022] The present invention describes a set of hanging rod protrusions 15 on the side of the hanging rod 14, and a hanging plate groove 18 on the upper part of the rotating hanging plate 16. The hanging rod 14 is adapted to the hanging plate groove 18 and is inserted into the hanging plate groove 18 so that the upper part of the rotating hanging plate 16 is hung on the hanging rod 14. The set of hanging rod protrusions 15 prevents the rotating hanging plate 16 from slipping off the hanging rod 14 during the cooling process of metal parts heat treatment. The front and rear sides of the rotating hanging plate 16 are in contact with the set of hanging rod protrusions 15. The lower part of the rotating hanging plate 16 has a hanging plate lower groove 17, which is symmetrically arranged on both sides of the rotating hanging plate 16.

[0023] Example 4:

[0024] Metal pipes are placed inside the hanging plate groove 17 of this utility model. The lower part of the rotating hanging plate 16 passes through the upper opening 02 of the box and is inserted into the cooling box 01. A set of hanging plate grooves 17 at the lower part of the rotating hanging plate 16 holds metal pipes. When the rotating disk 13 rotates, the rotating hanging plates 16 hanging on different hanging rods 14 are sequentially lowered into the cooling box 01 for cooling. The cooling time of each set of metal pipes in the cooling box 01 is exactly the time it takes for the rotating pressure rod 19 to rotate one revolution. The side of the support frame plate 03 has a circular support platform 07, and the rear side of the rotating disk 13 is in contact with the circular support platform 07. The circular support platform 07 limits the rotation of the rotating disk 13, so that the side of the rotating ring plate 09 is in contact with the rotating disk 13. The side of the circular support platform 07 has a second shaft 08, which passes through the rotating disk 13 and connects to the anti-detachment disc 22. The anti-detachment disc 22 prevents the rotating disk 13 from slipping off the second shaft 08 during the cooling process of the metal parts for heat treatment. The second shaft 08 supports the rotating disk 13 and ensures the axial position of the rotating disk 13. This device can continuously cool the metal tubes on the rotating hanging plate 16 at different positions, and the metal tubes that have been rotated out after cooling can be replaced manually.

[0025] Example 5:

[0026] The installation steps of this utility model are as follows: First, connect the side of the frame plate 04 to the cooling box 01. Then, pass the second shaft 08 through the rotating disk 13 and connect it to the anti-detachment disc 22. Pass the first shaft 06 through the support frame plate 03 and connect it to the limiting side column 21. Connect the strip connecting plate 11 to the rotating ring plate 09. Connect the connecting column 12 to the strip connecting plate 11. Connect the first shaft 06 to the connecting column 12 and the strip connecting plate 11 in sequence. Connect the rotating pressure rod 19 to the connecting column 12. Connect the hanging rod 14 to the rotating disk 13. Hang the upper part of the rotating hanging plate 16 on the hanging rod 14. Install the motor 20 on the motor mounting plate 05. Connect the rotating shaft of the motor 20 to the limiting side column 21.
