Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment production lines, and in particular to a heat treatment circulation device and an operation line for an anti-collision beam. Background Art

[0002] Heat treatment is a common metal treatment process used to improve the performance of materials. Anti-collision beams play a vital role in safety protection in automobile structures, and their materials and processing technology directly affect their performance and effectiveness. Heat treatment is a very critical step in the production process of anti-collision beams. Proper heat treatment can significantly improve the mechanical properties and durability of materials. At present, anti-collision beams are mostly prepared by rectangular tubes, and the tubes are heated and quenched in the early stage.

[0003] The invention patent application with the existing patent application number CN117512313A discloses a heat treatment forming device for high-temperature resistant seamless steel pipes, including a workbench, a heat treatment box located in the middle of the workbench, a conveying device symmetrically arranged on both sides of the heat treatment box, a motor fixed to the outer side of the heat treatment box, and two groups of heating tubes arranged in the upper and lower inner cavities of the heat treatment box. A pushing rack is arranged in the heat treatment box between the two groups of heating tubes.

[0004] As in the above technical solution, a conveying device is provided on both sides of the heat treatment box for conveying pipes; in the actual application process, a material transfer mechanism needs to be provided to transfer the pipes to the conveying device. At present, when feeding pipes, it is common to arrange several pipes in parallel, and then rely on a lifting cylinder to drive the bracket to lift the pipes close to the material transfer mechanism, and then rely on another cylinder to push the lifted pipes to the conveying device, but this feeding structure cannot achieve the positioning of the pipes. Therefore, during the pipe transportation, a guide wheel group will be provided between the conveying device and the heat treatment box to achieve the positioning of the pipes so that the pipes can enter the heat treatment box smoothly; because the setting of the guide wheel group will lead to the increase of the operation line and the increase of the occupied area, and the setting of the lifting cylinder and the pushing cylinder, especially the pushing cylinder needs to be set above the pipe, will cause the equipment structure to be not compact enough and easy to interfere with the stacking of pipes.

[0058] The anti-collision beam heat treatment circulation device and operation line of the present invention have the following beneficial effects compared with the prior art:

[0059] (1) A first table and a second table with a height difference are arranged on the first frame, wherein the first table is used to install a conveying roller group, a supporting roller group and a positioning mechanism, and the second table is used to place the pipe and the transfer mechanism. In this way, when transferring the pipe, the pipe can be automatically dropped onto the supporting roller group by relying on the height difference, and then the pipe can be placed on the conveying roller group by relying on the supporting roller group. Compared with the existing solution of lifting first and then pushing, this structure has the advantages of being more compact and occupying less space. At the same time, since the conveying roller group and the supporting roller group are both provided with positioning mechanisms, The positioning of the pipe can be realized, making it easier for it to enter the subsequent heat treatment process equipment. Since the guide wheel positioning components are reduced, the length of the operation line can be significantly reduced; (2) the transfer mechanism is formed by setting the guide frame, the flap and the end shaft, so that the end shaft can be connected through the power parts such as the motor to drive the flap to turn over, so that the pipe on the flap slides toward the supporting roller group, which improves the convenience of feeding; at the same time, the cleaning component is connected to the transfer mechanism through the connecting plate, and the inside of the pipe can be purged through the cleaning component to avoid the presence of impurities that affect the heat treatment effect;

[0060] (3) The connection plate of the cleaning component is connected to the transfer mechanism through the first part, and the cleaning component uses a three-way pipe fitting for air supply, one port of the three-way pipe fitting is connected to the end shaft of the transfer mechanism and connected to the connection plate, which can significantly improve the stability of the cleaning component assembly; and the cleaning component does not rely on the first frame for installation and fixation, which reduces the difficulty of integration and facilitates assembly and disassembly maintenance;

[0061] (4) A carrier is provided in the conveyor roller group for installing the positioning mechanism, wherein the carrier is connected to the first frame through the side bracket, and is slidably matched with the first sliding ring of the conveyor roller through the ring frame, so that when the positioning mechanism is installed on the vertical plate, the conveyor roller can support the carrier and the positioning mechanism to ensure the stability of the structure; at the same time, this structure makes the positioning mechanism closer to the center position of the conveyor roller, which facilitates the positioning mechanism to position the pipe;

[0062] (5) In the positioning mechanism, driven by the electric push rod, the electromagnet will move in the axial direction, thereby driving the pipe to move and adjust the position of the pipe. At the same time, this structure also makes the positioning mechanism suitable for positioning different types of pipes;

[0063] (6) In the cooling device of this production line, the roller is supported by a cooling pipe. After the heat of the pipe is transferred to the roller, the heat is quickly taken away by the cooling water flow in the cooling pipe to avoid affecting the bearing seat and power parts supporting the transmission. At the same time, the cooling pipe is also connected to the spray pipe so that the cooling water flow can be directly sprayed onto the pipe as a cooling water flow. This simplifies the structure of the cooling equipment and reduces the impact of heat on the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0082] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0083] like Figures 1 to 9 As shown, the anti-collision beam heat treatment circulation device of the present invention comprises a first frame 1, a conveying roller group 2, a supporting roller group 3, a transfer mechanism 4, a positioning mechanism 5 and a cleaning assembly 6;

[0084] like Figures 10 to 16 As shown, the anti-collision beam heat treatment operation line of the present invention includes the above-mentioned anti-collision beam heat treatment circulation device, and also includes a heating device 7, a cooling device 8 and a gas collection device 9.

[0085] like Figure 1 and Fig. 9 As shown, the first frame 1 has a first table 101 and a second table 102, the first table 101 is lower than the second table 102, and the second table 102 is used to support the anti-collision beam tube 100; the conveying roller group 2 is arranged on the first table 101, and is used to convey the anti-collision beam tube 100; the supporting roller group 3 is arranged on the first table 101, and the supporting roller group 3 and the conveying roller group 2 are staggered, and the supporting roller group 3 is used to support the anti-collision beam tube 100; the transfer mechanism 4 is arranged on the side of the second table 102 facing the first table 101, and is used to flip the anti-collision beam tube 100 onto the supporting roller group 3; the positioning mechanism 5 is arranged on both the conveying roller group 2 and the supporting roller group 3, and is used to adjust the position of the anti-collision beam tube 100;

[0086] As in the above structure, the second table 102 is used to place the anti-collision beam tube 100. A plurality of anti-collision beam tubes 100 are arranged in parallel. When they need to be transported, a pushing mechanism such as a cylinder is used to push the anti-collision beam tube 100 to advance. In this way, the frontmost anti-collision beam tube 100 will be transferred to the transfer mechanism 4.

[0087] Then the transfer mechanism 4 is activated to transfer the anti-collision beam tube 100 to the supporting roller group 3, and the positioning mechanism 5 located on the supporting roller group 3 will position the anti-collision beam tube 100 so that the position of the anti-collision beam tube 100 is correct;

[0088] Then, the supporting roller group 3 transfers the anti-collision beam tube 100 to the conveying roller group 2, and the positioning mechanism 5 on the conveying roller group 2 performs secondary positioning on the anti-collision beam tube 100, and then conveys the anti-collision beam tube 100 to the heating device 7;

[0089] In this structure, a first table 101 and a second table 102 with a height difference are arranged on the first frame 1, wherein the first table 101 is used to install the conveying roller group 2, the supporting roller group 3 and the positioning mechanism 5, and the second table 102 is used to place the anti-collision beam pipe 100 and the transfer mechanism 4, so that when the anti-collision beam pipe 100 is transferred, the pipe can be automatically dropped onto the supporting roller group 3 by relying on the height difference, and then the anti-collision beam pipe 100 can be placed on the conveying roller group 2 by relying on the supporting roller group 3; compared with the existing solution of lifting first and then pushing, this structure has the advantages of more compact structure and smaller space occupation; at the same time, since the positioning mechanism 5 is arranged on both the conveying roller group 2 and the supporting roller group 3, the positioning of the anti-collision beam pipe 100 can be realized, making it more convenient to enter the subsequent heat treatment process equipment, and since the conveying roller group 2 and the supporting roller group 3 are staggered, this reduces the guide wheel positioning components, so the length of the operation line can be significantly reduced;

[0090] like Figure 3As shown, the transfer mechanism 4 includes a guide frame 41, a flap 42 and an end shaft 43, wherein the guide frame 41 is arranged on the side of the second table 102 facing the first table 101; the flap 42 is a strip plate with a semicircular cross section, and the arc surface of the flap 42 is slidably matched with the guide frame 41; the end shaft 43 is arranged at both ends of the flap 42, and the end shaft 43 is supported by a bearing seat;

[0091] As in the above structure, the flap 42 is used to support the anti-collision beam tube 100, and the end shaft 43 is used to connect the motor. When the transfer mechanism 4 transports the anti-collision beam tube 100, the motor drives the flap 42 to rotate through the end shaft 43. At this time, the flap 42 will flip the anti-collision beam tube 100 down, and relying on the height difference between the two tables and the guidance of the guide frame 41, the anti-collision beam tube 100 will fall onto the supporting roller group 3. At this time, the supporting roller group 3 can be used to send the anti-collision beam tube 100 to the conveying roller group 2, and then the conveying roller group 2 can be used to send the anti-collision beam tube 100 to the heating device 7.

[0092] like Figure 2 , Figure 6 and Figure 7 As shown, the cleaning assembly 6 includes a connecting plate 61, a three-way pipe fitting 62 and an air induced draft hood 63, wherein the connecting plate 61 includes a first portion 611, a second portion 612 and a third portion 613; one side of the first portion 611 is connected to the flap 42, and the other side is connected to the end shaft 43; one end of the second portion 612 is connected to the first portion 611, and the other end is inclined toward the side close to the end shaft 43; one end of the third portion 613 is connected to the second portion 612; one end of the three-way pipe fitting 62 is connected to the end shaft 43, one end passes through the third portion 613, and the other end is a free end; the air induced draft hood 63 is connected and connected to and through one end of the three-way pipe fitting 62 passing through the third portion 613;

[0093] As in the above structure, the free end of the three-way pipe 62 is used to connect the blower. After the anti-collision beam pipes 100 are arranged in parallel, the blower sends air through the three-way pipe 62 and the induced draft hood 63 to purge the inside of the anti-collision beam pipe 100, thereby removing internal impurities and preventing the impurities from reacting during the heat treatment and affecting the heat treatment effect.

[0094] In this structure, the first part 611 of the connecting plate 61 is used to connect the flap 42 and the end shaft 43, the second part 612 connects the first part 611 and the third part 613, and the third part 613 is connected to the three-way pipe fitting 62, and one port of the three-way pipe fitting 62 is also connected to the end shaft 43; this allows the weight of the three-way pipe fitting 62 and the induced draft hood 63 to be directly borne by the bearing seat via the end shaft 43, and because the flap 42 and the guide frame 41 are slidably matched, the guide frame 41 will also share the weight, thereby ensuring the stability of the installation of the three-way pipe fitting 62 and the induced draft hood 63; this structure realizes the integration of the cleaning assembly 6 and the transfer mechanism 4, and there is no need to install the cleaning assembly 6 on the first frame 1, which improves the convenience of positioning during assembly;

[0095] Specifically, the pipe opening of the three-way pipe fitting 62 passes through the third portion 613 and is detachably connected to the induced draft hood 63, and the three-way pipe fitting 62 is connected to the end shaft 43 via a flange, thereby facilitating subsequent disassembly and maintenance;

[0096] Furthermore, in this structure, the flap 42, the connecting plate 61, the three-way pipe 62 and the induced draft hood 63 are relatively fixed, so their relative positions are accurate. As long as the anti-collision beam pipe 100 can be smoothly transferred to the flap 42, due to the parallel arrangement of multiple anti-collision beam pipes 100, it is ensured that the induced draft hood 63 can be aligned with the pipe opening of the anti-collision beam pipe 100, thereby realizing the purge work;

[0097] Furthermore, the second portion 612 is inclined and presents a flared structure relative to the first portion 611 , which can position the anti-collision beam tube 100 and ensure that the anti-collision beam tube 100 can be smoothly transferred to the flap 42 .

[0098] like Figure 5 As shown, the conveying roller set 2 includes a conveying roller 21 and a carrier 22, wherein the conveying roller 21 includes a supporting section 211, a limiting section 212 arranged on both sides of the supporting section 211, a first slip ring 213 arranged on the circumference of the limiting section 212, and a rotating shaft 214 arranged on the end surface of the limiting section 212, and the rotating shaft 214 is supported by a bearing seat; the carrier 22 is arranged on the first frame 1, and a part of the carrier 22 is slidably matched with the first slip ring 213; the positioning mechanism 5 is arranged on the part of the carrier 22 that is slidably matched with the first slip ring 213;

[0099] As in the above structure, the conveying roller 21 is used to convey the anti-collision beam tube 100, which is supported by the supporting section 211 and the anti-collision beam tube 100 is limited by the limiting section 212 to prevent the anti-collision beam tube 100 from accidentally deviating;

[0100] Before transportation, the anti-collision beam pipe 100 needs to be limited in position, and the limitation is achieved by the positioning mechanism 5 installed on the carrier 22;

[0101] Among them, the carrier 22 is fixedly connected to the first frame 1. In order to make the positioning mechanism 5 as close to the supporting section 211 as possible, the carrier 22 is partially extended to the limiting section 212 and slidingly cooperates with the first slip ring 213 on the limiting section 212. In this way, the positioning mechanism 5 is close to the supporting section 211 to realize the positioning of the anti-collision beam tube 100, and the supporting section 211 can support the extended part of the carrier 22 through the first slip ring 213, thereby ensuring the overall structural stability of the carrier 22 and the accurate position of the positioning mechanism 5.

[0102] like Figure 4 As shown, the carrier 22 includes a ring frame 221, a side frame 222 and a vertical plate 223, wherein the ring frame 221 is an arc-shaped plate structure, and the ring frame 221 is slidably matched with the first sliding ring 213; the side frame 222 is arranged on both sides of the ring frame 221 and connected to the first frame 1; the vertical plate 223 is arranged on the ring frame 221, and the positioning mechanism 5 is arranged on the vertical plate 223;

[0103] As in the above structure, in the carrier 22, it is connected to the first frame 1 through the side bracket 222, one end of the side bracket 222 extends to the supporting section 211 and is connected to the ring frame 221, the ring frame 221 is provided with an arc groove to slide with the first sliding ring 213, so as to transfer the weight to the conveying roller 21 through the ring frame 221; the vertical plate 223 is set on the ring frame 221 to carry the positioning mechanism 5.

[0104] like Figure 3 As shown, the supporting roller group 3 includes a supporting roller 31, a first guide rod 32, a sliding bracket 33, a bracket 34 and a cylinder 35, wherein the first guide rod 32 is provided at both ends of the supporting roller 31; the sliding bracket 33 is provided on the first frame 1, the first guide rod 32 penetrates the sliding bracket 33 and slides together; the bracket 34 is provided on the supporting roller 31, and the positioning mechanism 5 is provided on the bracket 34; the cylinder 35 is provided on the first frame 1, and the movable end of the cylinder 35 is connected to the bracket 34;

[0105] As in the above structure, the supporting roller group 3 is used to cooperate with the conveying roller group 2 to convey the anti-collision beam pipe 100; the bracket 34 on the supporting roller 31 is connected to the cylinder 35, and the positioning mechanism 5 is installed at the same time; when it is working, the anti-collision beam pipe 100 will slide onto the supporting roller 31, at this time the positioning mechanism 5 will first complete the positioning work of the anti-collision beam pipe 100, and then the cylinder 35 will drive the supporting roller 31 to fall, so that the anti-collision beam pipe 100 is overlapped on the conveying roller 21 of the conveying roller group 2, and the anti-collision beam pipe 100 can be conveyed;

[0106] Among them, in order to ensure the stable movement of the supporting roller 31 and reduce the radial force on the piston rod of the cylinder 35 when the anti-collision beam tube 100 falls, a first guide rod 32 is set at both ends of the supporting roller 31, and a sliding bracket 33 is set on the first frame 1 to cooperate with the first guide rod 32, which can realize the movement and guidance of the supporting roller 31. At the same time, the end face of the supporting roller 31 can be abutted against the sliding bracket 33 to avoid axial movement of the supporting roller 31, thereby preventing damage to the piston rod of the cylinder 35.

[0107] like Figure 8 As shown, the positioning mechanism 5 includes a fixed seat 51, an electric push rod 52, a second guide rod 53, an end plate 54 and an electromagnet 55, wherein the fixed seat 51 is connected to the conveying roller group 2 and / or the supporting roller group 3; the electric push rod 52 is arranged on the fixed seat 51; the second guide rod 53 passes through the fixed seat 51 and is coaxial with the electric push rod 52; the end plate 54 is connected to the second guide rod 53 and the movable end of the electric push rod 52; the electromagnet 55 is arranged on a side of the fixed seat 51 away from the end plate 54, and is connected to the second guide rod 53;

The positioning mechanism 5 on the conveying roller group 2 is connected to the vertical plate 223 through the fixing seat 51; the positioning mechanism 5 on the supporting roller group 3 is connected to the bracket 34 through the fixing seat 51;

[0109] When the positioning mechanism 5 is in motion, the electric push rod 52 drives the second guide rod 53 and the electromagnet 55 to move through the end plate 54, so that the electromagnet 55 is close to or away from the anti-collision beam tube 100. After the electromagnet 55 absorbs the anti-collision beam tube 100, the electric push rod 52 moves again to adjust the position of the anti-collision beam tube 100, thereby ensuring that the anti-collision beam tube 100 is in the correct position;

[0110] The positioning mechanism 5 of this structure has the advantage of being compact, and with the cooperation between the second guide rod 53 and the fixing seat 51 , the movement can be ensured to be stable and reliable.

[0114] like Figures 11 to 14 As shown, the cooling device 8 includes a second frame 81, a cooling pipe 82, a spray pipe 83, a first connecting pipe 84, a second connecting pipe 85, a support rod 86, a roller 87 and a water tank 88, wherein the second frame 81 is arranged on one side of the heating device 7; two cooling pipes 82 are arranged in parallel on the second frame 81, and the cooling pipes 82 are supported by a bearing seat; the spray pipe 83 is arranged between the two cooling pipes 82, and the spray pipe 83 is parallel to the cooling pipe 82; both ends of the first connecting pipe 84 are respectively connected to the The end of a cooling pipe 82 is rotatably connected; one end of a second connecting pipe 85 is rotatably connected to the end of a cooling pipe 82, and the other end of the second connecting pipe 85 is rotatably connected to the end of a spray pipe 83; one end of a support rod 86 is connected to the middle section of the first connecting pipe 84, and the other end is detachably connected to the end of the spray pipe 83 away from the second connecting pipe 85; a roller 87 is arranged on the cooling pipe 82; a water tank 88 is mounted on the roller 87, and the water tank 88 is slidably matched with the roller 87 to position the roller 87;

[0115] As described above, in the cooling device 8, the cooling pipe 82 is directly used as the support shaft of the roller 87, and the roller 87 is used to support the anti-collision beam pipe 100 after heating. In this way, the heat transferred to the roller 87 will be taken away by the cooling water flow flowing through the cooling pipe 82 to prevent local overheating.

[0116] Specifically, the cooling pipe 82 is supported by a bearing seat, and the cooling pipe 82 and the roller 87 are set as an integrated structure. A sprocket 89 is set on one side of the roller 87 to connect the motor and the chain to realize the driving action. The conveying roller 21 can be directly driven by the motor and the coupling; at the same time, this transmission structure is adapted to the rotation connection between the cooling pipe 82 and the first connecting pipe 84 and the second connecting pipe 85;

[0117] In this structure, in order to facilitate water circulation, a first connecting pipe 84 is provided to connect the two cooling pipes 82, so that water can be supplied through one cooling pipe 82, and after absorbing heat, the cold water will further enter the spray pipe 83 through the second connecting pipe 85, so as to be sprayed onto the anti-collision beam pipe 100 through the spray pipe 83, so as to achieve cooling of the anti-collision beam pipe 100, thereby making full use of the supplied water; wherein the first connecting pipe 84 and the second connecting pipe 85 are rotatably connected by a rotating water seal joint to avoid interfering with the rotation of the cooling pipe 82 and the roller 87;

[0123] The second positioning ring 883 also has an arc groove, and the first positioning ring 882 and the second positioning ring 883 are configured as a semicircular ring structure. After the first positioning ring 882 is connected to the second positioning ring 883, the water trough 88 is mounted on the roller 87, and due to the configuration of the second slip ring 884, it will not interfere with the rotation of the roller 87; since the water trough 88 rotates in coordination with multiple rollers 87, its position can be guaranteed to be stable.

[0124] like Fig.13 As shown, the spray pipe 83 includes an end pipe 831, a bottom pipe 832 and a top pipe 833, wherein one end of the end pipe 831 is rotatably connected to the port of the second connecting pipe 85; one end of the bottom pipe 832 and the top pipe 833 are both connected and penetrated with the other end of the end pipe 831, and the other end of the bottom pipe 832 is detachably connected to the support rod 86; the top pipe 833 partially corresponds to the bottom pipe 832, and the top pipe 833 and the bottom pipe 832 are provided with nozzles opposite to each other;

[0126] like Fig.16 As shown, the gas collecting device 9 includes a column 91, a side plate 92 and a gas collecting hood 93, wherein four columns 91 are arranged on the second frame 81; two side plates 92 are arranged opposite to each other, and the two side plates 92 are respectively connected to two columns 91, one of the side plates 92 is connected to the first connecting pipe 84, and the support rod 86 passes through the side plate 92; the other side plate 92 is connected to the spray pipe 83, and the spray pipe 83 passes through the side plate 92; the gas collecting hood 93 is arranged on the column 91 and corresponds to the spray pipe 83;

Since the cooling pipe 82 is positioned by the water tank 88 in the structure of the cooling device 8, the installation position accuracy of the first connecting pipe 84 is guaranteed, and then under the layout of the first connecting pipe 84 connected to the column 91, the installation positions of the spray pipe 83 and the gas collection hood 93 are also positioned, so as to achieve good coordination of the components to ensure the normal cooling work.

[0128] In some embodiments, the cooling device 8 and the gas collecting device 9 are enclosed by a sheet metal box.
