Description

Technical Field

[0001] The present application relates to the field of heat treatment equipment, and specifically to an intelligent heat treatment production line for producing a cab. Background Art

[0002] The car cab has to bear various forces during the driving process, such as the weight of the vehicle body, the weight of passengers and cargo, wind resistance during driving, impact force caused by road bumps, etc. Therefore, in the process of producing the cab, the materials that make up the cab are generally heat treated separately or the entire cab is heat treated after welding.

[0003] Heat treatment generally includes quenching, annealing, tempering and other processes. In the Chinese patent document with the announcement number CN222007908U, an energy-saving annealing furnace for heat treatment of carbon steel forging is disclosed, and the annealing furnace shell is specifically disclosed. A movable slide rail is provided in the annealing furnace shell, and a carrier is installed on the movable slide rail. A cooling pipe and a heat absorber are installed in the inner wall of the annealing furnace shell. A switching baffle for shielding any one of the cooling pipe and the heat absorber is provided in the annealing furnace shell. A moving component for driving the switching baffle to move is provided in the annealing furnace shell, and a heating plate for heating is provided on the carrier. The utility model can recover the waste heat through the heat absorber when a heating step is required, and can assist in heat preservation by absorbing the waste heat when heat preservation is required.

[0004] However, in the above patent, the heating plate as a heat source is only arranged on the carrier, resulting in poor temperature uniformity in the outer shell of the annealing furnace. Moreover, the parts are placed directly on the carrier, causing the temperature at the contact point between the parts and the heating plate to be too high, affecting the annealing effect. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present application provides an intelligent heat treatment production line for producing a cab.

[0006] The present application is implemented by the following technical solution: an intelligent heat treatment production line for producing a cab, comprising an annealing furnace, the annealing furnace comprising a shell and a loading platform, a pair of slide rails are provided under the shell, the loading platform is adaptively arranged on the pair of slide rails and can slide on the slide rails, a heating plate is provided on the top of the loading platform, a number of supporting bosses are provided on the heating plate, a number of heating rods are arranged on the inner wall of the shell, and the workpiece to be processed is arranged on the supporting bosses and is located on the inner side of the number of heating rods.

[0007] By adopting the above technical solution, the heat emitted by the heating plate mainly heats the workpiece in the vertical direction, while the heat emitted by the heating rod mainly heats the workpiece in the horizontal direction, thereby improving the uniformity of the heat treatment effect on the workpiece.

[0008] Optionally, the loading platforms include two, both of which are disposed on a pair of the slide rails, and the two loading platforms are respectively disposed on two sides of the shell.

[0009] By adopting the above technical solution, the two loading platforms can alternately enter the shell, which improves the operating efficiency, reduces the heat loss in the shell, and effectively improves the energy utilization rate.

[0011] By adopting the above technical solution, when the worktable is loading the workpiece, the hydraulic cylinder drives the shell to move to a high position. At this time, the worktable can slide on the slide rail and move to the bottom of the shell. Then the hydraulic cylinder drives the shell to move to a low position and makes the shell contact with the worktable. At this time, the workpiece is sealed on the inner side of the shell, which effectively reduces the heat loss and further improves the heat treatment efficiency.

[0012] Optionally, an opening is provided at the bottom of the shell, and when one of the loading platforms moves below the opening, the hydraulic cylinder drives the shell to move downward and covers the top of the loading platform, and the other loading platform is located outside the shell and is used for loading workpieces.

[0013] By adopting the above technical solution, after the workpiece on one stage is loaded, it can be moved to the bottom of the opening of the shell. At this time, the stage can be docked with the shell and heat treatment of the workpiece can be performed, while the other stage is away from the shell and the workpiece can be loaded. In this way, after one stage completes the heat treatment and moves away from the shell, the other stage can immediately enter the shell for heat treatment, which improves the smoothness of the connection process, and the shell can maintain a higher temperature, thereby reducing heat loss.

[0014] Optionally, the span between the two columns facing the worktable is greater than the width of the worktable.

[0015] By adopting the above technical solution, it is ensured that there is no mutual collision between the stage and the column when the stage slides on the slide rail, thereby improving the reliability of the stage's bearing function on the workpiece.

[0016] Optionally, a frame unit is provided on the top of the worktable, and the frame unit includes a plurality of placement areas interconnected with each other, and the workpiece is placed in the placement areas; the frame unit includes a transverse portion and a vertical portion, and the vertical portion includes a gasket, a threaded seat and a vertical rod, the gasket is arranged on the supporting boss, the threaded seat is arranged on the top of the gasket, and the lower portion of the vertical rod is adaptively screwed in the threaded seat; four sliding grooves are provided on the outer wall of the vertical rod, and the sliding grooves extend in the vertical direction, one end of the transverse portion is inserted in a sliding groove of one of the vertical rods, and the other end of the transverse portion is inserted in a sliding groove of another adjacent vertical rod, and the transverse portion can slide in the sliding groove.

[0017] By adopting the above technical solution, the height of the transverse part can be adjusted when the transverse part slides in the slide groove. In this way, the heights of several transverse parts can be adjusted individually, so that the shape and size of the placement area can be easier to control, so that different workpieces can be placed in matching placement areas, ensuring that each workpiece can be heated evenly while effectively improving space utilization.

[0018] Optionally, a vertical portion is provided at the top of each of the supporting bosses, and at least two of the transverse portions are inserted into one of the vertical rods; a plurality of flaring grooves are also provided in the slide groove, the width of the flaring grooves is greater than the width of the slide groove, and the plurality of flaring grooves are spaced apart in the vertical direction; the transverse portion comprises a pair of transverse rods, a pair of limit blocks and a threaded sleeve, one limit block is arranged in a flaring groove of one of the vertical rods, and the other limit block is arranged in a flaring groove of another adjacent vertical rod, one end of one of the transverse rods is connected to one of the limit blocks, one end of the other transverse rod is connected to the other limit block, one end of the threaded sleeve is connected to the other end of one of the transverse rods by a threaded connection, and the other end of the threaded sleeve is connected to the other end of the other transverse rod by a threaded connection.

[0019] By adopting the above technical solution, when the limit block is in a horizontal state and is located in the limit groove, the limit block is in a fixed state. At this time, the limit block can only move up and down in the limit groove and cannot enter the slide groove. When the size of the placement area needs to be adjusted, the limit block can be rotated to a vertical state. At this time, the limit block can slide from the flared groove into the slide groove, so that the position of the cross bar can be adjusted. When the cross bar moves to the flared groove of a suitable height, the limit block is rotated to a horizontal state to fix the position of the cross bar. Furthermore, after the threaded sleeve is completely screwed onto one cross bar, the two cross bars will be in a state of being separated from each other, so that the cross bar can be taken out from between the two vertical bars, which is convenient for quickly increasing or decreasing the number of the cross parts.

[0020] Optionally, the distance between the two cross bars is greater than the depth of the flaring groove, and the depth of the flaring groove is the same as the depth of the sliding groove.

[0021] By adopting the above technical solution, it is ensured that after the threaded sleeve is rotated onto one cross bar, there is a sufficient distance between the two cross bars, so that the cross bar and the limit block can be quickly removed.

[0022] Optionally, a receiving groove is provided on the top of the loading platform, an asbestos board is provided in the receiving groove, the heating plate is provided on the top of the asbestos board, the top of the asbestos board is located above the notch of the receiving groove, and the top of the asbestos board is provided with a first step surface; an asbestos cover is provided on the inner side of the shell, the heating rod is provided on the inner side of the asbestos cover, and a second step surface is provided on the bottom of the asbestos cover, and when the shell cover is provided on the top of the loading platform, the first step surface and the second step surface are in contact with each other.

[0023] By adopting the above technical solution, both the asbestos board and the asbestos cover have a thermal insulation effect and can reduce heat loss. At the same time, when the first step surface and the second step surface are in contact with each other, the stage and the shell can be in a well-sealed state, which facilitates the rapid increase of the temperature inside the shell.

[0024] Optionally, an annular groove is provided on the first step surface, a mesh plate is provided in the middle of the groove, an annular asbestos strip is provided on the top of the mesh plate, the top of the asbestos strip is located above the notch of the groove, and an air pipe is provided at the bottom of the mesh plate, the air pipe extends to the outside of the worktable, and the air pipe is used to transport protective gas into the groove.

[0025] By adopting the above technical solution, after the air pipe transports the protective gas into the groove, the mesh plate can disperse the protective gas, that is, the protective gas can enter the inner side of the shell in a relatively uniform state, thereby forming a protective atmosphere on the inner side of the shell to prevent the workpiece from being oxidized during the heat treatment process.

[0026] Compared with the prior art, this application has the following beneficial effects:

[0027] 1. A heating plate is arranged on the stage to realize the heating effect on the workpiece in the vertical direction. At the same time, a heating rod is arranged in the shell to realize the heating effect on the workpiece in the horizontal direction. In this way, the heating effect on the workpiece is more three-dimensional and uniform, which can significantly improve the heat treatment effect on the workpiece.

[0028] 2. A frame unit consisting of a horizontal portion and a vertical portion is arranged on the stage, and the size of the placement area in the frame unit can be adaptively adjusted according to the different shapes and sizes of the workpieces, thereby ensuring that several workpieces can be evenly placed on the frame unit, improving space utilization, and also improving the heat treatment effect on the workpieces.

[0029] 3. A first step surface is set on the asbestos board, and a second step surface is set on the asbestos cover. When the shell is docked with the stage, the first step surface and the second step surface can fit each other, thereby improving the heat insulation effect of the shell and reducing heat loss. At the same time, protective gas is transported into the groove through the air pipe. After passing through the asbestos board and the asbestos cover, the protective gas can enter the inner side of the shell and form a protective gas on the inner side of the shell, thereby preventing the workpiece from being oxidized during the heat treatment process.

[0046] Below, combined with the attached Figure 1-7 As well as specific implementation methods, the present application is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0047] Figure 1 is a schematic stereogram of the present application, Figure 2 is a schematic perspective view of the housing. Figure 1 and Figure 2 , an intelligent heat treatment production line for producing a cab, comprising an annealing furnace 1 for annealing a workpiece, the annealing furnace 1 comprising a shell 11, a loading platform 12 and a lifting mechanism 16, wherein there is one shell 11 and two loading platforms 12, a pair of slide rails 13 are arranged below the shell 11, the two loading platforms 12 are arranged on the pair of slide rails 13 and can slide on the slide rails 13, at the same time, one loading platform 12 is located on one side of the shell 11, and the other loading platform 12 is located on the other side of the shell 11. The lifting mechanism 16 comprises a hydraulic cylinder 161, a bottom plate 162 and a column 163, four columns 163 are respectively and one by one arranged at the four corners of the bottom plate 162, the shell 11 is located below the bottom plate 162 and is sleeved on the four columns 163, the hydraulic cylinder 161 is used to drive the shell 11 to move in the vertical direction, and the four columns 163 play a role in guiding and limiting the movement of the shell 11.

[0048] Figure 3 is a schematic stereogram of the stage. Figure 4 This is a reference diagram of the stage in its exploded state. Figure 3 and Figure 4 The top of the stage 12 is provided with a receiving groove 120, and an asbestos board 18 is provided in the receiving groove 120. A heating plate 14 is provided on the top of the stage 12 and on the asbestos board 18. The top of the asbestos board 18 is located above the notch of the receiving groove 120, and a first step surface 181 is provided on the top of the asbestos board 18. The bottom of the shell 11 is provided with an opening 110, and an asbestos cover 19 is provided on the inner side of the shell 11. A plurality of heating rods 15 are provided on the inner side of the shell 11 and on the asbestos cover 19, and a second step surface 190 is provided on the bottom of the asbestos cover 19.

[0049] See also Figure 2 and Figure 4In the initial state, the push rod of the hydraulic cylinder 161 is retracted, and the housing 11 is located at a high position. At this time, a loading platform 12 can be slid to the bottom of the housing 11. Since the span between the two columns 163 facing the loading platform 12 is greater than the width of the loading platform 12, it is ensured that the loading platform 12 will not collide with the columns 163 during the movement. When the loading platform 12 is moved into place, the push rod of the hydraulic cylinder 161 extends, so that the bottom of the housing 11 is connected to the top of the loading platform 12. At this time, the first step surface 181 and the second step surface 190 are attached to each other. In the process of the first step surface 181 and the second step surface 190 being attached to each other, the asbestos board 18 and the asbestos cover 19 will undergo a certain amount of deformation, thereby improving the tightness of the contact between the asbestos board 18 and the asbestos cover 19, so that the heat loss can be reduced. Furthermore, a groove 182 is provided on the first step surface 181, a mesh plate 183 is provided in the middle of the groove 182, an asbestos strip 184 is provided on the top of the mesh plate 183, the groove 182, the mesh plate 183 and the asbestos strip 184 are all annular, and an air pipe 185 is provided at the bottom of the mesh plate 183, one end of the air pipe 185 is connected to the mesh plate 183, and the other end of the air pipe 185 passes through the asbestos plate 18 and the stage 12 and is connected to the air source, and the air source conveys the protective gas into the groove 182 through the air pipe 185. After entering the groove 182, the protective gas passes through the asbestos plate 18 and the asbestos cover 19 and enters the inner side of the housing 11, so that a protective atmosphere can be formed on the inner side of the housing 11, thereby preventing the workpiece from being oxidized during the heat treatment process and improving the heat treatment effect. The mesh plate 183 is a hard plate, which ensures that the air pipe 185 and the groove 182 will not be closed during the docking and extrusion of the asbestos board 18 and the asbestos cover 19. At the same time, the mesh plate 183 can also disperse the airflow, thereby ensuring that the protective gas can enter the inner side of the shell 11 more evenly, thereby improving the protection effect on the workpiece.

[0050] When the stage 12 is docked with the shell 11, the heating plate 14 and the heating rod 15 start heating at the same time. The heating plate 14 can provide vertical heating to the workpiece, and the heating plate 14 can provide horizontal heating to the workpiece. In this way, the two heat flows can heat the workpiece in all directions, and the uniformity of heating is greatly improved, which significantly improves the heating and heat treatment effect of the workpiece. Under the heat insulation effect of the asbestos board 18 and the asbestos cover 19, the heat loss in the shell 11 can be reduced and the energy utilization rate can be improved. Further, when one stage 12 is in a state of docking with the shell 11, the other stage 12 can load the workpiece. In this way, after one stage 12 completes the heat treatment and evacuates the shell 11, the other stage 12 can be docked with the shell 11 immediately. At this time, the shell 11 is still in a relatively high temperature state under the protection of the asbestos cover 19, which can increase the initial heat and maximize the energy utilization rate.

[0051] Figure 5 This is a reference diagram of the assembly status of the frame unit and the stage. Figure 5 A plurality of support bosses 140 are provided on the top of the heating plate 14, and a frame unit 17 is provided above the stage 12, including a transverse portion 172 and a vertical portion 173. Each support boss 140 is provided with a vertical portion 173, and a plurality of transverse portions 172 are provided between two adjacent vertical portions 173.

[0052] Figure 6 is a schematic three-dimensional diagram of a frame unit, Figure 7 yes Figure 6 The enlarged structure reference diagram at A in the middle. Figure 6 and Figure 7 The vertical portion 173 includes a gasket 1731, a threaded seat 1732 and a vertical rod 1733. The gasket 1731 can be movably or fixedly connected to the support boss 140. The threaded seat 1732 is arranged on the top of the gasket 1731. In this way, the gasket 1731 plays a buffering and shock-absorbing role on the threaded seat 1732, so as to prevent the threaded seat 1732 from directly contacting the support boss 140 made of asbestos material and causing damage to the support boss 140. The lower part of the vertical rod 1733 is adaptively screwed into the threaded seat 1732, so that the vertical rod 1733 can be detachably connected to the support boss 140, and the height of each vertical rod 1733 can be adjusted independently and in small amounts. Four slide grooves 1734 are symmetrically arranged on the outer wall of the vertical rod 1733. The slide grooves 1734 extend in the vertical direction, and each slide groove 1734 is spaced apart in the vertical direction. A plurality of flaring grooves 1735 are arranged in each slide groove 1734. The transverse portion 172 includes a pair of transverse bars 1721, a pair of stoppers 1722 and a threaded sleeve 1723. One stopper 1722 is disposed in a flared groove 1735 of a vertical bar 1733, and another stopper 1722 is disposed in a flared groove 1735 of another adjacent vertical bar 1733. One end of one transverse bar 1721 is connected to one stopper 1722, and one end of another transverse bar 1721 is connected to another stopper 1722. One end of the threaded sleeve 1723 is threadedly connected to the other end of one transverse bar 1721, and the other end of the threaded sleeve 1723 is threadedly connected to the other end of another transverse bar 1721. At least two transverse bars 1721 are disposed on each vertical bar 1733. Thus, a plurality of transverse bars 1721 and a plurality of vertical bars 1733 form a plurality of placement areas 171, and workpieces can be placed in the placement areas 171.

[0053] Furthermore, the width of the flaring groove 1735 is greater than the width of the slide groove 1734, the depth of the flaring groove 1735 is the same as the depth of the slide groove 1734, and the limit block 1722 is adaptively arranged in the flaring groove 1735. Specifically, when the limit block 1722 is in a horizontal state, the limit block 1722 can only slide up and down in the flaring groove 1735. When the limit block 1722 is in a vertical state, the limit block 1722 can slide from the flaring groove 1735 to the slide groove 1734. 4, so that when the height of the cross bar 1721 needs to be adjusted, the cross bar 1721 and the limit block 1722 can be rotated (the limit block 1722 is rotated to a vertical state), and then the cross bar 1721 and the limit block 1722 are moved up and down. When the limit block 1722 moves to the expanded groove 1735 of the corresponding height, the cross bar 1721 and the limit block 1722 are rotated in the opposite direction (the limit block 1722 is rotated to a horizontal state), and thus the height of the cross bar 1721 is adjusted. When it is necessary to remove any one of the transverse parts 172 from the frame unit 17, the threaded sleeve 1723 can be completely rotated onto a cross bar 1721. At this time, the two cross bars 1721 are in a state of separation from each other, and the cross bars 1721 and the limit blocks 1722 can be taken out at the same time. When it is necessary to add a transverse part 172 to the frame unit 17, a limit block 1722 can be placed in a slide groove 1734 of a vertical rod 1733, and then the other limit block 1722 can be placed in the slide groove 1734 of another limit rod. In this way, the two cross bars 1721 will be in a state of approaching each other, and then the threaded sleeve 1723 is rotated to connect the two cross bars 1721 through the threaded sleeve 1723, so that the installation of the transverse part 172 is completed. By setting different numbers of transverse portions 172 and adjusting the height of the transverse portions 172, the size of the placement area 171 can be adjusted, so that the size of the placement area 171 can be adapted to the size of the workpiece placed therein, and then several workpieces can be staggered and placed in the frame unit 17. In this way, it is avoided that several workpieces are stacked on each other, the space utilization rate of the frame unit 17 is improved, and it is ensured that the heat generated by the heating plate 14 and the heating rod 15 can heat all the workpieces more three-dimensionally and evenly, thereby significantly improving the heat treatment effect on the workpieces.

[0054] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
