DETAILED DESCRIPTION

[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The following describes a casting processing heat treatment furnace according to an embodiment of the present application with reference to the accompanying drawings.

[0026] like Figure 1-Figure 5 As shown, the casting processing heat treatment furnace of the embodiment of the present application may include: a stand 1, a feeding mechanism 2, a stopper 3, a cover body 4 and two shielding mechanisms 5.

[0027] The two ends of the stand 1 are respectively provided with grooves 11 , and the grooves 11 are used to provide an accommodating space for the feeding mechanism 2 .

[0028] The feeding mechanism 2 is installed on the platform 1 , and the feeding mechanism 2 includes a conveying component 21 and a plurality of material placing components 22 .

[0029] The conveying assembly 21 is connected to the groove 11 , and is used to drive the plurality of material placing assemblies 22 and the castings to be processed to move at a uniform speed.

[0030] A plurality of material placement assemblies 22 are respectively installed on the conveying assembly 21 . The material placement assemblies 22 are used to provide a containing space for the casting to be processed. The material placement assemblies 22 include a first support body 221 and a second support body 222 .

[0031] The first support body 221 is connected to the conveying assembly 21 , the second support body 222 is pivotally connected to the first support body 221 , and the second support body 222 and the first support body 221 are arranged in a triangle.

[0032] It can be understood that the second support body 222 and the first support body 221 are arranged in a triangle. The triangular structure has good heat collection performance and can form a high heat zone in the triangular area, thereby improving the thermal utilization rate of flame heating.

[0033] An opening 223 is provided at the bottom of the first support body 221 . The stopper 3 is disposed on the stand 1 . The stopper 3 is arranged opposite to one of the openings 223 . An inclined surface 31 is provided on the stopper 3 .

[0034] It should be noted that the stopper 3 described in this embodiment can pass through the opening 223, and the stopper 3 interferes with the second support body 222, thereby pushing the second support body 222 to flip, and the second support body 222 turns over the casting.

[0035] The cover body 4 is arranged on the stand 1 , and a combustion device 41 is installed on the cover body 4 , and the combustion device 41 is used for flame heating of the casting.

[0036] The two shielding mechanisms 5 are connected to the stand 1 and the cover body 4 respectively. A plurality of through slots 50 are provided on the shielding mechanism 5 , and the conveying assembly 21 passes through the through slots 50 .

[0037] It can be understood that both sides of the cover body 4 are provided with inlets (not shown in the figure), and the shielding mechanism 5 can cover the inlets, thereby reducing the heat loss inside the cover body 4 while ensuring that the casting can enter the inside of the cover body 4.

[0038] Specifically, relevant technicians need to flame heat a batch of castings (eg, flanges, gaskets, etc.) to change the metal properties of the casting surfaces and extend their service life.

[0039] When the device is started, the feeding mechanism 2 and the combustion device 41 begin to operate, and the relevant technicians can place one or more castings inside the material placement assembly 22 with the help of a robot arm or manually, and make the castings fit on the second support body 222.

[0040] It can be understood that the discharge position of the casting is far away from the heat treatment processing position, which improves the safety of the processing process to a certain extent.

[0041] The conveying assembly 21 drives the material placing assembly 22 to move. When the material placing assembly 22 moves close to a shielding mechanism 5, one shielding mechanism 5 can be opened autonomously (this working condition can be obtained by an infrared sensor). After the casting enters the interior of the cover body 4, the other shielding mechanism 5 is closed.

[0042] The placing assembly 22 carries the casting into the interior of the cover body 4, and the combustion device 41 flame heats the casting. After a period of flame heating, the second support body 222 abuts against the inclined surface 31 of the block 3, and the inclined surface 31 can flip the second support body 222, so that the casting resting on the second support body 222 is flipped onto the first support body 221, thereby realizing the turning over of the casting, and the combustion device 41 continues to flame heat the casting.

[0043] The material placing assembly 22 drives the casting to approach another shielding mechanism 5, and the shielding mechanism 5 opens autonomously. After the material placing assembly 22 drives the casting to leave the cover body 4, the other shielding mechanism 5 closes.

[0044] As the conveying assembly 21 operates, the placing assembly 22 can flip over autonomously, and under the action of gravity, the castings are separated from the placing assembly 22 and enter an external collecting device.

[0045] At the same time, another material placement assembly 22 carries the casting into the interior of the cover body 4, and the above steps are repeated, thereby realizing automatic heat treatment, simplifying the operation steps of the workers, and improving the safety during the operation.

[0046] In one embodiment of the present application, Figure 1-Figure 3 As shown, the first support body 221 includes a support plate 2211 , a first inclined plate 2212 and two reinforcing plates 2213 .

[0047] The support plate 2211 is connected to the conveying assembly 21 , the first inclined plate 2212 is connected to the support plate 2211 , and two reinforcing plates 2213 are symmetrically arranged between the support plate 2211 and the first inclined plate 2212 .

[0048] In one embodiment of the present application, Figure 1-Figure 3 As shown, the second support body 222 includes a second inclined plate 2221 and a top block 2222, wherein the second inclined plate 2221 is pivotally connected to the first inclined plate 2212, the top block 2222 is slidably connected to the second inclined plate 2221, one top block 2222 is arranged opposite to the stopper 3, and the bottom position of the top block 2222 is between the top and bottom positions of the inclined surface 31.

[0049] Specifically, when the conveying assembly 21 drives the placing assembly 22 to move inside the cover body 4, the inclined surface 31 of the stopper 3 first passes through the opening 223, and the inclined surface 31 contacts the top block 2222. The top block 2222 moves upward, and the top block 2222 exerts force on the second inclined plate 2221, and the second inclined plate 2221 flips over, thereby pushing the casting to turn over, and the casting is attached to the first inclined plate 2212.

[0050] It should be noted that the top block 2222 is slidably connected to the support plate 2211 and the second inclined plate 2221 respectively. When the top block 2222 passes through the inclined surface 31, the top block 2222 is reset under the action of gravity, thereby pulling the second inclined plate 2221 to reset.

[0051] In one embodiment of the present application, Figure 2 As shown, the conveying assembly 21 includes two sprocket sets 211 , two conveying chains 212 and a driving device 213 .

[0052] Among them, two sprocket groups 211 are installed inside the corresponding grooves 11, two conveying chains 212 are meshed and connected to the corresponding sprocket groups 211, and the driving device 213 is installed on the stand 1, and the output shaft of the driving device 213 is connected to one end of a sprocket group 211.

[0053] Specifically, during the operation of the conveying assembly 21, the driving device 213 drives a sprocket set 211 to start rotating, and under the transmission action of the conveying chain 212, the two sprocket sets 211 rotate synchronously, thereby driving the placing assembly 22 and the casting placed therein to move together.

[0054] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the shielding mechanism 5 includes a door body 51 and a pulling assembly 52 .

[0055] The door body 51 is slidably connected to the outer wall of the cover body 4 , and the pulling assembly 52 includes a plurality of pulleys 521 , two rope bodies 522 , a connecting plate 523 and a hydraulic telescopic rod 524 .

[0056] Among them, two pulleys 521 among the multiple pulleys 521 are symmetrically arranged on the door body 51, and the other two pulleys 521 among the multiple pulleys 521 are symmetrically arranged on the cover body 4. One end of the two rope bodies 522 is connected to a pulley 521 on the door body 51, and the rope body 522 is wrapped around the outer side of a pulley 521 on the cover body 4. The connecting plate 523 is connected to the other ends of the two rope bodies 522, and the hydraulic telescopic rod 524 is installed on the stand 1, and the telescopic end of the hydraulic telescopic rod 524 is connected to the connecting plate 523.

[0057] It should be noted that a controller (not shown in the figure) is provided on the platform 1, the hydraulic telescopic rod 524 is connected to the controller, and the infrared sensor is connected to the controller.

[0058] Specifically, when the infrared sensor detects a signal that the casting is close to the shielding mechanism 5, the infrared sensor sends an operation signal to the controller, and the controller sends an operation signal to the hydraulic telescopic rod 524. The hydraulic telescopic rod 524 pulls the connecting plate 523 to move, and the connecting plate 523 pulls the rope body 522. The rope body 522 moves on the pulley 521. The rope body 522 pulls the door body 51 to move, and the door body 51 moves up. The entrance of the cover body 4 opens, and the material placement assembly 22 and the casting enter the interior of the cover body 4.

[0059] In one embodiment of the present application, Figure 1 , Figure 3 and Figure 4 As shown, a first limiting assembly 61 is provided between the door body 51 and the cover body 4 , and a second limiting assembly 62 is provided between the top block 2222 and the support plate 2211 and the second inclined plate 2221 .

[0060] It should be noted that the first limit assembly 61 and the second limit assembly 62 described in this embodiment may respectively include a guide groove (not shown in the figure) and a guide rod (not shown in the figure), and their specific connection structures have been disclosed in the prior art, so they will not be described in detail here.

[0061] In one embodiment of the present application, Figure 5 As shown, the combustion device 41 includes a burner 411 , a flamethrower 412 and two rotators 413 .

[0062] The burner 411 is connected to the cover body 4 , the flamethrower 412 is arranged inside the cover body 4 , the burner 411 is connected to the flamethrower 412 , and two rotators 413 are respectively installed between the cover body 4 and the flamethrower 412 .

[0063] It should be noted that the specific working methods of the burner 411 and the flamethrower 412 described in this embodiment have been disclosed in the prior art, so they will not be described in detail here.

[0064] It is understandable that the rotator 413 can drive the flamethrower 412 to rotate, thereby changing the flame spraying angle of the flamethrower 412 .

[0065] In summary, the casting processing heat treatment furnace of the embodiment of the present application drives multiple material placement components to run at a uniform speed through the conveying component. Within the cover body, the castings to be processed can be turned over autonomously, thereby realizing automated heat treatment, simplifying the workers' operating steps, and improving safety during the operation process.
