Description

Technical Field

[0001] This application relates to the field of galvanized iron drum production technology, specifically to a galvanized iron drum production and forming device. Background Technology

[0002] Galvanized iron drums are iron drums with a zinc coating on their surface. Their biggest feature is that they can prevent metal from rusting and corroding, thus improving the service life of steel products. In the production process of galvanized iron drums, a rib-stretching machine is used to process corrugated ribs on the drum body to increase the mechanical strength of the metal drum.

[0003] A search revealed that patent application CN219309883U discloses a hydraulic expansion machine for processing metal drums. When processing a workpiece using the expansion machine body, a cooling liquid can be evenly sprayed onto the workpiece surface through a nozzle, thus achieving cooling. This solves the problem of existing expansion machines lacking a cooling mechanism for the workpiece, resulting in the inability to dissipate heat from deformed areas during processing, potentially causing injury to workers. However, the liquid spraying cooling solution has limitations. To prevent the liquid from affecting the workpiece processing, an additional liquid recovery device is required, which can increase production costs. To address this issue, this application proposes a galvanized iron drum production forming device. Summary of the Invention

[0004] The purpose of this application is to address the limitations of the above-mentioned cooling technology using liquid spraying, which requires additional liquid recovery devices to prevent the liquid from affecting the processing of the workpiece, thus increasing production costs. This application provides a galvanized iron drum production and forming device.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A galvanized iron drum production and forming apparatus, comprising:

[0007] The base plate has a sleeve installed horizontally at its top, and an inner tube is rotatably installed inside the sleeve. The inner tube extends along the length of the sleeve, and both ends of the inner tube penetrate the sleeve.

[0008] An air pump is installed on the top of the base plate, and its output end is connected to the end of the inner tube. The end of the sleeve is equipped with a rib expansion mechanism, and the end of the inner tube passes through the middle of the rib expansion mechanism and is equipped with a nozzle assembly.

[0009] The drive mechanism, which is located on the inner tube, is used to drive the movement of the rib expansion mechanism.

[0010] Furthermore, a vertical plate is connected to the top of the base plate, and a first frustum block is constructed on one side of the vertical plate. It is close to the expansion rib mechanism, and its outer diameter gradually decreases from the vertical plate toward the expansion rib mechanism. A sleeve passes through the first frustum block, and an air guide groove is opened on the outer side of the first frustum block. It extends along the length direction of the first frustum block and has multiple grooves arranged in a ring along the axis of the first frustum block.

[0011] Furthermore, a fixed plate is connected to the base plate, the end of the sleeve slides through the fixed plate, and a connecting block is constructed on it. A lead screw is rotatably installed on the base plate, the connecting block slides with the base plate and is threaded with the lead screw, and a driving component is installed on the base plate to drive the lead screw to rotate.

[0012] Furthermore, the nozzle assembly includes a cylindrical block, and a plurality of nozzles are arranged in a ring around the cylindrical block, all of which are connected to the inner tube, and the output direction of the nozzles is towards the periphery of the expansion mechanism.

[0013] Furthermore, the driving mechanism includes a first spur gear installed at the end of the inner tube, a drive motor installed on the sleeve, a second spur gear installed at its output end, which meshes with the first spur gear, a second frustum block threadedly fitted on the outer side of the inner tube, the second frustum block slidingly fitted with the sleeve, its outer diameter gradually decreasing from the end of the inner tube toward its end, and the second frustum block abutting against the expansion rib mechanism.

[0014] Furthermore, a rotary joint is installed at the end of the inner tube. The rotary joint is fixed to the periphery of the sleeve via an L-shaped plate. A flexible hose is installed on the rotary joint and is connected to the output end of the air pump.

[0015] Furthermore, the L-shaped plate has a first section and a second section that are connected to each other. The end of the first section is connected to the periphery of the rotary joint, and the end of the second section is fixed to the periphery of the sleeve.

[0016] Furthermore, the L-shaped plate and the air pump are located on the same side of the sleeve, and pipe clamps are installed on the side of the L-shaped plate away from the first spur gear, which are used to fix the hose.

[0017] The beneficial effects of this application are as follows:

[0018] This application employs an inner tube design. After the workpiece undergoes rib expansion processing, the air pump operates, allowing air to quickly pass through the inner tube and be sprayed out through the nozzle assembly. This disrupts the air inside the workpiece and accelerates its flow. When the air comes into contact with the deformed parts of the workpiece, it carries away the heat, thereby achieving the purpose of cooling the workpiece. Compared with existing technologies, the gas cooling method is less likely to affect the workpiece processing, less likely to cause waste, and less likely to increase additional production costs, making it practical.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-6 As shown, one embodiment of this application discloses a galvanized iron drum production and forming apparatus, comprising:

[0028] The base plate 1 has a sleeve 2 horizontally arranged on its top. An inner tube 3 is rotatably installed inside the sleeve 2. The sleeve 2 and the inner tube 3 are on the same axis. The inner tube 3 extends along the length of the sleeve 2 and both ends of the inner tube 3 penetrate the sleeve 2.

[0029] The air pump 4 is a compression type air pump, which belongs to the prior art. It is installed on the top of the base plate 1, and its output end is connected to the end of the inner tube 3. The end of the sleeve 2 is equipped with a rib expansion mechanism 5. The rib expansion mechanism 5 adopts the structural principle of a rib expansion machine. When it is inserted into the inside of the cylindrical workpiece and works, it can squeeze the inner wall of the workpiece outward to form a protruding annular rib. The end of the inner tube 3 passes through the middle of the rib expansion mechanism 5, and a nozzle assembly 6 is installed on it. When the air pump 4 works, air can quickly pass through the inner tube 3 and be sprayed out through the nozzle assembly 6, which can disturb the air inside the workpiece and make its flow speed faster. When the air comes into contact with the deformed part of the workpiece, it can carry away the heat on it, thereby achieving the purpose of cooling the workpiece. It should be noted that in this application, a refrigeration device can also be installed at the output end of the air pump 4 to reduce the air temperature and improve its cooling effect. Compared with the prior art, the gas cooling method is less likely to affect the processing of the workpiece, less likely to cause waste, and less likely to increase additional production costs, which is practical.

[0030] The drive mechanism 7 is mounted on the inner tube 3 and is used to drive the expansion mechanism 5 to move.

[0031] It should be noted that when the device is used in a production line, two devices are required. The two devices need to be symmetrically slidably installed on both sides of the production line. This is a conventional technical method. When the cylindrical workpiece moves between the two devices, the two devices can move relative to each other and abut against the two ends of the workpiece to fix the workpiece. At this time, the sleeve 2 and the inner tube 3 can be inserted into the workpiece to perform rib expansion processing and cool the deformed parts of the workpiece.

[0032] This application employs an inner tube 3 design. After the workpiece completes the rib expansion process, the air pump 4 operates, allowing air to quickly pass through the inner tube 3 and be sprayed out through the nozzle assembly 6. This disrupts the air inside the workpiece and accelerates its flow. When the air comes into contact with the deformed parts of the workpiece, it can carry away the heat, thereby achieving the purpose of cooling the workpiece. Compared with the prior art, the gas cooling method is less likely to affect the workpiece processing, less likely to cause waste, and less likely to increase additional production costs, making it practical.

[0033] like Figure 3 and Figure 4As shown, in some embodiments, a vertical plate 8 is connected to the top of the base plate 1. A first frustum block 9 is constructed on one side of the vertical plate 8, which is close to the expansion mechanism 5. Its outer diameter gradually decreases from the vertical plate 8 toward the expansion mechanism 5. When both devices slide toward the workpiece, the end of the workpiece will abut against the side of the first frustum block 9. At this time, the first frustum blocks 9 at both ends of the workpiece can abut against and fix it. The sleeve 2 passes through the first frustum block 9. An air guide groove 10 is provided on the outer side of the first frustum block 9. It extends along the length of the first frustum block 9 and is arranged in a ring along the axis of the first frustum block 9. When the end of the workpiece contacts the side of the first frustum block 9, the air sprayed from the nozzle assembly 6 can be discharged from the inside of the workpiece through the air guide groove 10 to reduce the influence of the fast-flowing airflow on the workpiece and make it less likely to deviate from its original position.

[0034] like Figure 3 As shown, in some embodiments, a fixed plate 11 is connected to the base plate 1, the end of the sleeve 2 slides through the fixed plate 11, the sleeve 2 slides with the vertical plate 8, and a connecting block 12 is constructed on it. A lead screw 13 is rotatably installed on the base plate 1, the lead screw 13 extends along the length direction of the sleeve 2, the connecting block 12 slides with the base plate 1, a slider 1201 is constructed at the bottom of the connecting block 12, and a groove 1202 is opened at the top of the base plate 1. The groove 1202 extends in the same direction as the lead screw 13. The slider 1201 slides with the groove 1202 and is threaded with the lead screw 13. When the lead screw 13 rotates, the connecting block 12 and the slider 1201 can slide along the length direction of the groove 1202, thereby driving the sleeve 2 to slide. At this time, the length of the inner tube 3 inserted into the workpiece can be adjusted, so that the rib forming process can be performed at different positions of the workpiece. A driving component 14 is installed on the base plate 1. The driving component 14 is a motor, and its output end is connected to the lead screw 13, which is used to drive the lead screw 13 to rotate.

[0035] like Figure 4 As shown, in some embodiments, the nozzle assembly 6 includes a cylindrical block 15, with a plurality of nozzles 16 arranged in a ring around the cylindrical block 15, all of which are connected to the inner tube 3. After passing through the inner tube 3, the gas can be ejected from the nozzles 16 around the cylindrical block 15. The inner diameter of the nozzles 16 is smaller than the inner diameter of the inner tube 3, which can accelerate the gas flow rate and improve the cooling effect. The output direction of the nozzles 16 is all towards the periphery of the expansion mechanism 5. After the expansion mechanism 5 is reset, the gas ejected from the nozzles 16 can directly contact the deformed part of the workpiece.

[0036] like Figures 3-5As shown, in some embodiments, the drive mechanism 7 includes a first spur gear 17 mounted on the end of the inner tube 3, a drive motor 18 mounted on the sleeve 2, and a second spur gear 19 mounted on its output end, which meshes with the first spur gear 17. When the drive motor 18 is working, the inner tube 3 can be rotated through the meshing first spur gear 17 and second spur gear 19. A second frustum block 20 is threaded on the outer side of the inner tube 3, and the outer side of the end of the inner tube 3 is threaded. The thread at the end of the inner tube 3 passes through the middle of the second frustum block 20, and the second frustum block 20 slides with the sleeve 2. A transverse block 2001 is constructed on the periphery of the second frustum block 20, and a transverse groove 2002 is opened in the sleeve 2. The transverse block 2001 slides with the transverse groove 2002. The outer diameter of the inner tube 3 gradually decreases from the end of the inner tube 3 toward its end. The second frustum block 20 abuts against the expansion mechanism 5. The main working principle of the existing expansion machine is to use the inclined surface to abut against the rigid block punch (i.e., the expansion block) to make it extend radially, thereby squeezing the inner wall of the workpiece outward to form a protruding annular rib on the outer surface of the workpiece, that is, to make the barrel wall undergo radially increased bulging deformation. In this application, the second frustum block 20 is used to replace the inclined surface. When the drive motor 18 drives the inner tube 3 to rotate, the second frustum block 20 can be driven to slide along the length of the inner tube 3. When the side of the second frustum block 20 abuts against the expansion block in the expansion mechanism 5, it can be forced to extend radially to complete the expansion processing of the workpiece.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, a rotary joint 21 is installed at the end of the inner tube 3. The rotary joint 21 is a prior art technology. The rotary joint 21 is fixed to the periphery of the sleeve 2 by an L-shaped plate 22, thereby fixing the rotary joint 21. A flexible hose 23 is installed on the rotary joint 21. The flexible hose 23 is a rubber tube and is connected to the output end of the air pump 4. With this design, on the one hand, when the sleeve 2 slides, the flexible hose 23 can bend with the movement of the sleeve 2. On the other hand, when the inner tube 3 rotates, the flexible hose 23 is not easily twisted under the action of the rotary joint 21, so as to facilitate the passage of air.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the L-shaped plate 22 has a first segment 2201 and a second segment 2202 that are connected to each other. The first segment 2201 and the second segment 2202 are vertically connected. The end of the first segment 2201 is connected to the periphery of the rotary joint 21, and the end of the second segment 2202 is fixed to the periphery of the sleeve 2.

[0039] like Figure 1 and Figure 2As shown, in some embodiments, the L-shaped plate 22 and the air pump 4 are located on the same side of the sleeve 2, and pipe clamps 24 are installed on the side of the L-shaped plate 22 away from the first spur gear 17. Pipe clamps 24 are installed on the outer sides of the first section 2201 and the second section 2202. The pipe clamps 24 are U-shaped and are used to fix the hose 23. This can protect the hose 23, making it less likely to twist when the sleeve 2 moves, and making it less likely for the hose 23 to contact the first spur gear 17 and wear out, thereby extending the service life of the device.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
