Description

Technical Field

[0001] This utility model relates to the field of fastener tempering technology, specifically a tempering device for fastener tempering. Background Technology

[0002] Utility model application CN202222696652.6 discloses a tempering device for fasteners. By setting a rotatable stirring block inside the tempering chamber and a groove on the outer surface of the stirring block, the fasteners piled up on the bottom of the inner wall of the tempering chamber can be easily stirred.

[0003] The aforementioned device agitates the fasteners inside the conditioning chamber using a stirring block. When the fasteners are flipped to the top of the conditioning chamber, they fall down. During the fall, they collide with the components inside the conditioning chamber and the inner wall of the chamber, and the fasteners also collide with each other, which can easily cause damage to the fasteners, affecting the production quality of fastening and the conditioning effect. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a tempering device for fasteners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tempering apparatus for fastener quenching and tempering, comprising:

[0007] tempering furnace;

[0008] A rotating shaft is rotatably connected inside a tempering furnace. A fixed sleeve is fixedly fitted on the rotating shaft. Four sets of circumferentially distributed support rods are fixedly connected to the outer surface of the fixed sleeve. A fixed mesh plate is fixedly connected to the end of the support rod away from the fixed sleeve.

[0009] A clamping assembly for clamping and fixing fasteners, the clamping assembly is disposed on a support rod and can move up and down along the support rod.

[0010] Fasteners are placed on fixed mesh plates, and clamping components press on the fasteners. The clamping components can be moved back and forth along the support rod to spread the fasteners flat on the fixed mesh plates, preventing them from stacking together. Fasteners can be poured onto the four fixed mesh plates one by one, and the clamping components hold and fix the fasteners on the fixed mesh plates, preventing the fasteners from falling off during rotation and from being damaged by collision during tempering. This improves the quality of the fasteners and the tempering effect, and allows for tempering of a large number of fasteners at the same time.

[0011] Furthermore, the clamping assembly includes a clamping mesh plate with a fixed through groove. The clamping mesh plate passes through the support rod via the fixed through groove. The clamping mesh plate is located above the fixed mesh plate and has a gap. A connector is fixedly installed on the surface of the clamping mesh plate. The connector has two guide through grooves. The connector passes through the support rod via the guide through grooves. A limit plate is fixedly fitted on the support rod. An extrusion plate is slidably connected to the support rod. The extrusion plate is located above the connector. A high-temperature spring is fitted on the support rod and is located between the extrusion plate and the limit plate.

[0012] Under the elastic force of the high-temperature spring, the clamping mesh plate is pressed tightly against the surface of the fastener, preventing the fastener from falling off during rotation and avoiding collision damage during tempering, thus improving the quality of the fastener.

[0013] Furthermore, the clamping assembly also includes four guide cavities arranged circumferentially on the fixed sleeve. A high-temperature resistant steel wire rope is provided inside each guide cavity, with both ends of the high-temperature resistant steel wire rope extending through the guide cavity. One end of the high-temperature resistant steel wire rope is fixedly connected to the center of the surface of the connector, and the other end of the high-temperature resistant steel wire rope is fixedly connected to a pull rod located at the front end of the fixed sleeve.

[0014] Pulling the high-temperature resistant steel wire rope with the pull rod causes the connector to move the clamping mesh plate upward, creating space between the clamping mesh plate and the fixed mesh plate for fasteners, making operation easier and less strenuous.

[0015] Furthermore, a motor bracket is fixedly installed at the end of the tempering furnace away from the door, and a drive motor is installed on the motor bracket. The output end of the drive motor is fixedly connected to one end of the rotating shaft. A bearing seat is fixedly installed on the inner wall of the tempering furnace near the door, and the other end of the rotating shaft is rotatably connected to the bearing seat.

[0016] Furthermore, the bottom surface of the inner wall of the tempering furnace is provided with a discharge port, and the discharge port is provided with a sealing door that is hinged to the tempering furnace.

[0017] Furthermore, the bottom surface of the extrusion plate is provided with a plurality of universal ball bearings, which are in contact with the surface of the connector.

[0018] The use of omnidirectional ball bearings facilitates the forward and backward movement of the connectors and clamping plates, improving the smoothness of the movement and preventing excessive friction between the connectors and the extrusion plate from hindering movement.

[0019] Furthermore, the end of the fixed sleeve and both sides of the guide cavity are also fixedly installed with snap-fit ​​components, and the pull rod engages with the snap-fit ​​components.

[0020] The pull rod engages with the locking mechanism to prevent the pull rod from colliding with the bearing housing during rotation, thus avoiding the entanglement of the high-temperature steel wire rope. Attached Figure Description

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] This utility model provides, for example Figure 1-6 The fastener tempering apparatus shown includes:

[0031] Tempering furnace 1;

[0032] Rotating shaft 2 is rotatably connected inside tempering furnace 1. A fixed sleeve 3 is fixedly fitted on the rotating shaft 2. Four sets of circumferentially distributed support rods 4 are fixedly connected to the outer surface of the fixed sleeve 3. A fixed mesh plate 5 is fixedly connected to the end of the support rod 4 away from the fixed sleeve 3.

[0033] Clamping component 6 is used to clamp and fix fasteners. Clamping component 6 is located on support rod 4 and can move up and down along support rod 4.

[0034] When fasteners need tempering, the operator pulls the clamping assembly 6 upwards, pours the fasteners to be tempered onto the fixed mesh plate 5, releases the clamping assembly 6 so that it falls and presses onto the fasteners, and can pull the clamping assembly 6 back and forth along the support rod 4 to spread the fasteners on the fixed mesh plate 5 flat, avoiding the fasteners from stacking together. The fasteners can be poured onto the four fixed mesh plates 5 one by one, and the clamping assembly 6 clamps and fixes the fasteners on the fixed mesh plates 5 to prevent the fasteners from falling off during rotation and from being damaged by collision during tempering, thus improving the quality of the fasteners and the tempering effect. A large number of fasteners can be tempered at the same time. The rotating shaft 2 drives the fixed sleeve 3, support rod 4 and fixed mesh plate 5 to rotate, so that the fasteners are heated evenly in the tempering furnace 1, improving the quality of the tempering work.

[0035] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 5 Included with instruction manual Figure 6The clamping assembly 6 includes a clamping mesh plate 7, which has a fixed through groove 8. The clamping mesh plate 7 passes through the support rod 4 through the fixed through groove 8. The clamping mesh plate 7 is located above the fixed mesh plate 5 and has a gap. A connector 9 is fixedly installed on the surface of the clamping mesh plate 7. The connector 9 has two guide through grooves 10. The connector 9 passes through the support rod 4 through the guide through grooves 10. A limit plate 11 is fixedly installed on the support rod 4. A pressing plate 12 is slidably connected to the support rod 4. The pressing plate 12 is located above the connector 9. A high-temperature spring 13 is installed on the support rod 4. The high-temperature spring 13 is located between the pressing plate 12 and the limit plate 11.

[0036] When the fastener is placed on the fixed mesh plate 5, the clamping mesh plate 7 moves upward along the support rod 4 through the fixed through groove 8. The clamping mesh plate 7 drives the connector 9 to move upward along the support rod 4 through the guide through groove 10. The connector 9 pushes the extrusion plate 12 upward. The extrusion plate 12 applies pressure to the high-temperature spring 13. The high-temperature spring 13 deforms and contracts under pressure. The upward movement of the clamping mesh plate 7 and the fixed mesh plate 5 creates a space for placing the fastener. The operator places the fastener on the fixed mesh plate 5. Under the force of the high-temperature spring 13, the extrusion plate 12 pushes the connector... The component 9 and the clamping mesh plate 7 move downwards, and the clamping mesh plate 7 presses on the fastener. The operator pushes and pulls the clamping mesh plate 7 back and forth. The clamping mesh plate 7 and the connecting component 9 move back and forth along the support rod 4 through the fixed through groove 8 and the guide through groove 10, respectively. During the back and forth movement of the clamping mesh plate 7, the fasteners that are stacked together are separated to prevent the fasteners from stacking together. Under the elastic force of the high temperature spring 13, the clamping mesh plate 7 is pressed tightly on the surface of the fastener to prevent the fastener from falling off during rotation and to prevent the fastener from being damaged by collision during tempering, thereby improving the quality of the fastener.

[0037] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The clamping assembly 6 also includes a guide cavity 14. There are four guide cavities 14 distributed circumferentially on the fixing sleeve 3. A high-temperature resistant steel wire rope 15 is provided in the guide cavity 14.

One end of the high-temperature resistant steel wire rope 15 is fixedly connected to the center of the surface of the connector 9, and the other end of the high-temperature resistant steel wire rope 15 is fixedly connected to a pull rod 16. The pull rod 16 is located at the front end of the fixing sleeve 3.

[0038] When placing the fasteners on the fixed mesh plate 5, the operator pulls the high-temperature resistant steel wire rope 15 through the pull rod 16. The high-temperature resistant steel wire rope 15 pulls the connector 9, causing the clamping mesh plate 7 to move upward, so that a space is created between the clamping mesh plate 7 and the fixed mesh plate 5 to place the fasteners, which facilitates operation and saves effort.

[0039] Refer to the instruction manual appendix Figure 2Included with instruction manual Figure 3 A motor bracket 17 is fixedly installed at the end of the tempering furnace 1 away from the door.

A bearing seat 19 is fixedly installed on the inner wall of the tempering furnace 1 near the door. The other end of the rotating shaft 2 is rotatably connected to the bearing seat 19.

[0040] The drive motor 18 starts working, and the drive motor 18 drives the rotating shaft 2 to rotate along the bearing seat 19. The rotating shaft 2 drives the fixed sleeve 3, the support rod 4 and the fixed mesh plate 5 to rotate, so that the fasteners are heated evenly in the tempering furnace 1, which improves the quality of tempering.

[0041] Refer to the instruction manual appendix Figure 3 The bottom surface of the inner wall of the tempering furnace 1 is provided with a discharge port 20, and a sealing door 21 is provided on the discharge port 20 and hinged to the tempering furnace 1.

[0042] During discharge, the sealing door 21 on the discharge port 20 is opened, the clamping mesh plate 7 is moved upward, the fixed mesh plate 5 is rotated, and the fasteners on the fixed mesh plate 5 fall into the tempering furnace 1. The fasteners are discharged through the discharge port 20.

[0043] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The bottom surface of the extrusion plate 12 is provided with multiple universal balls 22, which are in contact with the surface of the connector 9.

[0044] The universal ball bearings 22 facilitate the forward and backward movement of the connector 9 and the clamping mesh plate 7, improving the smoothness of the movement and preventing the connector 9 from being unable to move due to excessive friction with the extrusion plate 12.

[0045] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 4 The end of the fixed sleeve 3 and the two sides of the guide cavity 14 are also fixedly installed with snap-fit ​​parts 23, and the pull rod 16 is engaged with the snap-fit ​​parts 23.
