Description

Technical Field

[0001] The present application relates to the technical field of annealing furnaces, and in particular to an automatic feeding device for annealing furnaces. Background Art

[0002] Annealing is a preparatory heat treatment process widely used in production. Annealing of most machine parts and mold blanks can not only eliminate the internal stress and composition and structural inhomogeneity of castings, forgings and welded parts, but also improve and adjust the mechanical properties and process properties of steel.

[0003] The existing annealing process is to feed the annealing material into the annealing furnace through the annealing feeding device, then close the furnace door, then slowly heat the metal to a certain temperature, maintain it for a sufficient time, then cool it at an appropriate speed, and then transport the annealing material out to complete the annealing.

[0004] The above-mentioned prior art solutions have the following defects: the existing annealing feeding device is located in the annealing furnace throughout the annealing process, which can easily cause damage to the annealing feeding device, and one annealing feeding device can only feed one annealing furnace during annealing. When there are multiple annealing furnaces, multiple annealing feeding devices need to be equipped. Summary of the invention

[0005] In order to enable the annealing feeding device to perform annealing feeding on multiple annealing furnaces, the present application provides an automatic feeding device for annealing furnaces.

[0006] The above technical objectives of this application are achieved through the following technical solutions: An automatic loading device for an annealing furnace comprises a supporting base, a movable base and a fixed base, wherein the movable base is provided with wheels and the vehicle is connected to a driving device, the fixed base is arranged inside the annealing furnace, a movable structure for driving the supporting base to move is arranged above the movable base, and the movable structure is connected to a clamping structure for fixing or separating the movable structure and the supporting base, and the supporting base can slide back and forth above the movable base and the fixed base.

[0007] By adopting the above scheme, when annealing and loading are required, the driving device drives the mobile base to move in front of the annealing furnace, and then the mobile structure drives the support base containing the annealing material to move above the fixed base, so as to send the annealing material into the annealing furnace, and then the furnace door is closed for annealing. The mobile base can then load the next annealing furnace without waiting for the annealing to be completed; when the annealing is completed, the mobile base moves in front of the fixed base, the clamping structure is fixedly connected to the support base, and then the mobile structure moves the support base to the mobile base, so as to take the annealing material out of the annealing furnace, thereby enabling the annealing and loading device to anneal multiple annealing furnaces.

[0008] Optionally, the movable structure includes a screw and a movable platform, a threaded sleeve is fixedly connected to the lower surface of the movable platform, the threaded sleeve and the screw are threadedly connected, the screw is rotatably connected to the movable base, and one end of the screw is rotatably connected to a rotating motor.

[0009] By adopting the above solution, the rotating motor drives the lead screw to rotate, thereby driving the threaded sleeve and the moving platform to move along the lead screw, so that the moving platform drives the supporting base to move above the moving base and the fixed base.

[0010] Optionally, the clamping structure includes a clamping rod, which is fixedly connected to the mobile platform, a clamping hole is provided on the side surface of the supporting base, a clamping groove is provided on the side surface of the clamping hole, the clamping rod is inserted into the clamping hole, a transmission cavity is provided in the clamping rod, and a pin hole is provided at the clamping rod opposite to the clamping groove, the pin hole is connected to the transmission cavity, a clamping pin is slidably connected in the pin hole, the clamping pin is hinged with a connecting rod at one end of the transmission cavity, the connecting rod is hinged with a sliding rod, the sliding rod is slidably connected in the transmission cavity, the sliding rod is perpendicular to the clamping pin, and a spring is sleeved on the outer side of the sliding rod.

[0011] By adopting the above scheme, when the supporting base is located above the moving base, the bayonet pin is stuck in the bayonet slot, thereby connecting the moving platform and the supporting base. When the supporting base is located on the fixed base, the sliding rod slides to one end of the lead screw, pulling the sliding rod to move in a direction away from the fixed base, thereby driving the connecting rod to move, thereby driving the bayonet pin to completely slide into the pin slot, and then the moving base moves in a direction away from the fixed base, causing the connecting rod to slide out of the connecting hole, thereby separating the moving platform and the supporting base.

[0012] Optionally, the sliding rod is connected to an unlocking rod, the threaded sleeve is provided with an unlocking groove, the unlocking groove is connected to the transmission chamber, the unlocking rod is slidably connected in the unlocking groove, and when the threaded sleeve slides to one end of the screw close to the fixed base, the mobile base presses the unlocking rod completely into the unlocking groove, and at the same time the unlocking rod drives the pin to slide out of the slot.

[0013] By adopting the above scheme, when the support base is moved from the mobile base to the fixed base, that is, when the mobile platform moves to the end of the lead screw close to the fixed base, the unlocking rod abuts against the surface of the mobile base, thereby completely squeezing the unlocking rod into the unlocking groove, thereby driving the sliding rod to move, thereby driving the connecting rod and the bayonet to move, so that the bayonet is completely retracted into the pin hole, and then the mobile base moves to the side away from the fixed base, so that the connecting rod slides out of the bayonet hole, so that the mobile platform and the support base are separated. When annealing is completed, after the mobile base is moved to the fixed base, the connecting rod is inserted into the bayonet hole, and then the motor is rotated to drive the lead screw to rotate, thereby driving the mobile platform to move toward the end of the lead screw away from the fixed base, so that the unlocking rod is separated from the surface of the mobile base, and the spring rebound drives the sliding rod and the connecting rod to move, so that the bayonet is inserted into the bayonet slot, so that the mobile platform and the support base are connected, so that the mobile platform drives the support base to move from the fixed base to the top of the mobile base, and then the mobile base transports the annealed material to the next process.

[0014] Optionally, the length of the locking groove along the direction of the locking rod is much longer than the diameter of the locking pin.

[0015] By adopting the above solution, since the movable platform moves away from the fixed base while the latch pin is inserted into the slot, the path of the latch pin in the slot is an oblique line, so that the length of the slot along the direction of the connecting rod is sufficient for the latch pin to extend, making the transmission smoother.

[0016] Optionally, a plurality of rollers are disposed above the movable base and the fixed base, and the support base is placed above the rollers.

[0017] By adopting the above scheme, rollers are set to reduce the friction resistance of the support base when it moves over the mobile base and the fixed base, thereby reducing energy consumption, making the support base move more smoothly over the mobile base and the fixed base, and also reducing the wear of the support base.

[0018] Optionally, the movable base and the fixed base are provided with a connecting structure.

[0019] By adopting the above scheme, in the process of moving the support base above the mobile base and the fixed base, the interaction force generated may cause the mobile base and the fixed base to move relative to each other, thereby causing problems in the movement of the support base. Therefore, the mobile base and the fixed base are connected by setting a connecting structure to avoid relative movement of the mobile base and the fixed base during the movement of the support base.

[0020] Optionally, the connecting structure includes a rotating shaft and an L-plate, the rotating shaft is rotatably connected to the mobile base, one end of the L-plate is fixedly connected to the fixed base, the rotating shaft is connected to a driving motor that drives the rotating shaft to rotate, and the end of the rotating shaft facing away from the mobile base is fixedly connected to a clamping plate. When the mobile base and the fixed base need to be connected, the driving motor drives the rotating shaft to rotate and drives the clamping plate to move into the gap between the L-plate and the fixed base.

[0021] By adopting the above scheme, the fixed base and the movable base are brought close to each other, and then the driving motor drives the rotating shaft to rotate, thereby driving the card plate to rotate, so that the card plate rotates to the gap between the L plate and the fixed plate, thereby limiting the displacement of the card plate, thereby limiting the displacement of the movable base, thereby preventing the movable base and the fixed base from moving relative to each other during the process of the support base moving over the movable base and the fixed base.

[0022] Optionally, the connection structure is provided in two groups, and the two groups of L-plates are away from each other.

[0023] By adopting the above solution, the two groups of L plates further limit the displacement of the movable base, thereby further ensuring the stability of the support base moving above the movable base and the fixed base.

[0024] Optionally, a connection groove is opened on the surface of the fixed base, and the L-plate is arranged in the connection groove.

[0025] By adopting the above solution, the fixed base and the movable base can be better fitted together, and the contact area between the fixed base and the movable base can be increased.

[0026] In summary, this application has the following technical effects: 1. By setting up a fixed base, a movable base and a supporting base, the annealing material is placed on the supporting base, and the supporting base is moved from the movable base to the fixed base, and then the movable base can continue to automatically load other annealing furnaces, so that the annealing loading device can anneal and load multiple annealing furnaces; 2. The rollers are set to make the support base move more smoothly on the mobile base and the fixed base; 3. A connection structure is provided to prevent relative displacement between the mobile base and the fixed base during movement of the support base. BRIEF DESCRIPTION OF THE DRAWINGS

The lead screw 41 is rotatably connected to the moving base 2, and one end of the lead screw 41 is rotatably connected to a rotating motor 411. The rotating motor 411 drives the lead screw 41 to rotate, thereby driving the threaded sleeve 421 and the moving platform 42 to move along the lead screw 41, so that the moving platform 42 drives the supporting base 1 to move above the moving base 2 and the fixed base 3.

The rollers 6 are arranged to reduce the friction resistance of the support base 1 when it moves above the mobile base 2 and the fixed base 3, thereby reducing energy consumption, making the support base 1 move more smoothly above the mobile base 2 and the fixed base 3, and also reducing the wear of the support base 1.

When the threaded sleeve 421 slides to the end of the lead screw 41 close to the fixed base 3, the mobile base 2 completely presses the unlocking rod 523 into the unlocking groove 422, and at the same time, the unlocking rod 523 drives the bayonet 52 to slide out in the slot 12.

[0034] Reference Figure 4 and Figure 5When the support base 1 is located above the mobile base 2, the latch pin 52 is stuck in the latch slot 12, thereby connecting the mobile platform 42 and the support base 1; when the support base 1 is moved above the mobile base 2 to above the fixed base 3, that is, when the mobile platform 42 moves to the end of the lead screw 41 close to the fixed base 3, the unlocking rod 523 abuts against the surface of the mobile base 2, thereby completely squeezing the unlocking rod 523 into the unlocking slot 422, thereby driving the sliding rod 522 to move, thereby driving the connecting rod 521 and the latch pin 52 to move, so that the latch pin 52 is completely retracted into the pin hole 512, and then the mobile base 2 moves to the side away from the fixed base 3, so that the connecting rod 51 slides out of the connecting hole 11, The movable table 42 is separated from the supporting base 1; when the annealing is completed, the movable base 2 is moved to the fixed base 3, and the clamping rod 51 is inserted into the clamping hole 11, and then the motor 411 is rotated to drive the screw 41 to rotate, thereby driving the movable table 42 to move toward the end of the screw 41 away from the fixed base 3, so that the unlocking rod 523 is separated from the surface of the movable base 2, and the spring rebound drives the sliding rod 522 and the connecting rod to move, so that the locking pin 52 is inserted into the clamping groove 12, thereby connecting the movable table 42 and the supporting base 1, so that the movable table 42 drives the supporting base 1 to move from the fixed base 3 to the top of the movable base 2, and then the movable base 2 transports the annealed material to the next process.

[0035] Reference Figure 6 , the mobile base 2 and the fixed base 3 are provided with a connection structure 7. In the process of moving the support base 1 over the mobile base 2 and the fixed base 3, the interaction force generated may cause the mobile base 2 and the fixed base 3 to move relative to each other, thereby causing problems in the movement of the support base 1. Therefore, the mobile base 2 and the fixed base 3 are connected by providing a connection structure 7 to avoid relative movement of the mobile base 2 and the fixed base 3 during the movement of the support base 1.

When the mobile base 2 and the fixed base need to be connected, the driving motor 711 drives the rotating shaft 71 to rotate and drives the clamping plate 712 to move to the gap between the L plate 72 and the fixed base 3. The connection structure 7 is provided with two groups, and the two groups of L plates 72 are separated from each other. Bring the fixed base 3 and the movable base 2 close together, then drive the motor 711 to drive the rotating shaft 71 to rotate, thereby driving the clamping plate 712 to rotate, so that the clamping plate 712 rotates to the gap between the L plate 72 and the fixed plate, thereby limiting the displacement of the clamping plate 712, thereby limiting the displacement of the movable base 2, thereby preventing the movable base 2 and the fixed base 3 from moving relative to each other during the movement of the support base 1 above the movable base 2 and the fixed base 3.

[0037] The specific implementation principle of the present application is as follows: when material annealing is required, the material to be annealed is placed above the supporting base plate, and then the mobile base 2 is moved with the supporting base plate and the annealing material thereon to the front of the annealing furnace 8, the mobile base 2 is moved to insert the rotating shaft 71 into the connecting groove 31, and then the driving motor 711 is driven to rotate to drive the clamping plate 712 to rotate, so that the clamping plate 712 is rotated to between the L plate 72 and the bottom of the connecting groove 31, so that the L plate 72 limits the clamping plate 712, and then limits the mobile base 2, so that the mobile base 2 and the fixed base 3 will not be relatively displaced, and then the rotating motor 411 is rotated to drive the lead screw 41 to rotate, thereby driving the threaded sleeve 421 and the mobile base 3 to rotate. The platform 42 moves toward the fixed base 3, so that the movable platform 42 pushes the supporting base 1 to move, so that the supporting base 1 moves above the movable base 2 to above the fixed base 3. At the same time, when the movable platform 42 moves to the end of the lead screw 41 close to the fixed base 3, the unlocking rod 523 abuts against the surface of the movable base 2, so that the unlocking rod 523 is completely squeezed into the unlocking groove 422, thereby driving the sliding rod 522 to move, thereby driving the connecting rod 521 and the bayonet 52 to move, so that the bayonet 52 is completely retracted into the pin hole 512, and then the movable base 2 moves to the side away from the fixed base 3, so that the connecting rod 51 slides out of the connecting hole 11, so that the movable platform 42 and the supporting base 1 are separated. Then, the driving motor 711 drives the rotating shaft 71 to rotate, so that the clamping plate 712 is rotated out between the L plate 72 and the bottom of the connecting groove 31, and then the mobile base 2 is moved away from the fixed base 3, the furnace door is closed, and the annealing furnace 8 anneals the material, and the mobile base 2 can repeat the above operation to load other annealing furnaces 8, so that the automatic loading device can load multiple annealing furnaces 8 without waiting for the annealing to be completed.
