The mounting shaft is in sliding connection with the mounting disc, a plurality of expansion blocks are arranged on the mounting shaft in the circumferential direction, the expansion blocks are connected with the mounting shaft through connecting rods, and the other end of each expansion block is in sliding connection with the corresponding sliding groove. Through the arrangement of the rib expansion mechanism, when a plurality of expansion blocks expand outwards synchronously, the ribs on the outer edges of the circumferences of the expansion blocks enable the side wall of the barrel body of the metal barrel to protrude outwards and generate plastic deformation, and finally a ring rib structure is formed. As the metal barrel does not need to rotate, the technical problem that the ring ribs are dislocated and deviated due to the fact that the metal barrel is unstable in positioning and prone to sliding is effectively solved.

Description

Technical Field

[0001] This utility model belongs to the technical field of barrel making equipment, specifically relating to a metal barrel body rib expansion device. Background Technology

[0002] Metal drums are important packaging containers, widely used in chemical, petroleum, light industry, and food industries for product packaging due to their high strength, corrosion resistance, and safety. Especially in the packaging of hazardous materials and concealed military supplies, their storage, transportation, loading and unloading, and usage performance are unmatched by other packaging materials, and they are reusable, have recycling value, and offer good ecological benefits. During the manufacturing process of metal drums, to improve the mechanical strength of the drum body, it is often necessary to process annular reinforcing ribs, also known as ring ribs. There are many methods for processing ring ribs, and roll forming is one of the commonly used methods at present. The principle is to roll the drum body using a roll forming machine. During this process, the pressure roller of the roll forming machine moves perpendicular to the drum body, causing the drum body to undergo localized plastic deformation along the normal direction of the pressure roller at the contact point, ultimately forming the ring rib.

[0003] Roll forming is a relatively mature process with a wide range of applications. However, during the processing of the ring ribs, the barrel body is prone to unstable positioning and slippage, leading to defects such as misalignment and skewing of the ring ribs. Moreover, during the roll forming process, the pressure rollers can easily leave scratches on the inner and outer surfaces of the metal barrel, affecting its overall appearance. Utility Model Content

[0004] The purpose of this invention is to provide a metal barrel body expansion device to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A metal drum body expansion device includes a base, on which a conveying mechanism, a transmission mechanism, and an expansion mechanism are provided. The expansion mechanism includes a mounting base, one end of which is fixedly provided with a mounting plate. The mounting plate has multiple radial sliding grooves. The mounting base is slidably connected to a mounting shaft, which passes through the center of the mounting plate and is slidably connected to the mounting plate. The mounting shaft has multiple expansion blocks along the circumferential direction. The expansion blocks are connected to the mounting shaft by a connecting rod. One end of the connecting rod is hinged to the expansion block, and the other end of the connecting rod is hinged to the outer wall of the mounting shaft. The expansion blocks and sliding grooves are arranged one-to-one, and the other end of each expansion block is slidably connected to the corresponding sliding groove.

[0007] As a further improvement, the outer edge of the expansion block is a rounded convex ridge, and the curvature of the outer edge of the expansion block matches the curvature of the inner wall of the metal barrel ring rib.

[0008] As a further improvement, a first hydraulic cylinder is fixedly installed on the side of the mounting base away from the mounting plate, and the output end of the first hydraulic cylinder is fixedly connected to the mounting shaft.

[0009] As a further improvement, the transmission mechanism includes a base plate, which is fixedly connected to the side of the machine base. A slide rail is fixedly mounted on the base plate, and a slide table is slidably connected on the slide rail. A mounting base is fixedly mounted on the slide table. A lead screw is rotatably mounted on the base plate. The lead screw and the slide rail are both set parallel to the mounting shaft. The slide table and the lead screw are threadedly rotatably connected. A motor is fixedly connected to the base plate, and the output shaft of the motor is fixedly connected to one end of the lead screw.

[0010] As a further improvement, the conveying mechanism includes a transmission chain rotatably mounted on the machine base, with multiple positioning fixtures for clamping the metal barrels on the transmission chain, and a second hydraulic cylinder above the transmission chain. The second hydraulic cylinder is fixedly connected to the machine base, and a pressure plate is fixedly connected to the output end of the second hydraulic cylinder, with the pressure plate engaging with the outer surface of the metal barrel.

[0011] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0012] This utility model provides a metal barrel body expansion rib device. By setting up an expansion rib mechanism, when multiple expansion blocks expand outward simultaneously, the protruding ridges on the outer circumference of the expansion blocks cause the sidewall of the metal barrel to bulge outward and undergo plastic deformation, ultimately forming a ring rib structure. During the ring rib processing, the metal barrel does not need to rotate or move its axial position, thus effectively solving the technical problem in the prior art where the ring ribs are misaligned and offset due to unstable positioning and easy slippage of the metal barrel.

[0013] By setting up a transmission mechanism, the distance that the expansion mechanism extends into the metal barrel body can be accurately controlled, effectively reducing the positional error of the ring ribs on the metal barrel body.

[0014] Since the expansion mechanism is located inside the metal barrel, it will not cause scratches on the outer surface of the metal barrel. Moreover, the metal barrel does not need to be rotated, and the protrusions of the expansion blocks will not cause obvious scratches on the inner wall of the metal barrel, thus ensuring the appearance of the metal barrel to the greatest extent.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. However, those skilled in the art will understand that the embodiments described below are only some embodiments of this utility model, not all embodiments, and are only used to illustrate this utility model, and should not be regarded as limiting the scope of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0021] like Figure 1-4As shown, a metal drum body expansion device includes a base 1, on which a conveying mechanism 2, a transmission mechanism 3, and an expansion mechanism 4 are provided. The expansion mechanism 4 includes a mounting base 401, with a mounting plate 402 fixedly mounted at one end of the mounting base 401. The mounting plate 402 has multiple radial sliding grooves 4021. A mounting shaft 403 is slidably connected to the mounting base 401. The mounting shaft 403 passes through the center of the mounting plate 402 and is slidably connected to the mounting plate 402. Multiple expansion blocks 404 are provided along the circumferential direction of the mounting shaft 403. The expansion blocks 404 are connected to the mounting shaft 403 by a connecting rod 405, with one end of the connecting rod 405 hinged to the expansion blocks 404. The other end of the connecting rod 405 is hinged to the mounting shaft 403. Each expansion block 404 is provided with two parallel connecting rods 405 between it and the mounting shaft 403, so that the length direction of the expansion block 404 is always parallel to the mounting shaft 403. The expansion blocks 404 are provided one-to-one with the sliding grooves 4021. The other end of each expansion block 404 is slidably connected to the corresponding sliding groove 4021. Specifically, the sliding groove 4021 is a T-groove or a dovetail groove. The sliding groove 4021 can limit the movement trajectory of the expansion block 404 and make the expansion block 404 only move radially along the mounting plate 402, and also provide force support for the expansion block 404. The horizontal sliding of the mounting shaft 403 changes the angle between the connecting rod 405 and the mounting shaft 403, thereby changing the distance between the expansion block 404 and the mounting shaft 403, and causing multiple expansion blocks 404 to expand outward or contract inward simultaneously. When multiple expansion blocks 404 expand outward simultaneously, the edges of the expansion blocks 404 cause the inner wall of the metal barrel 5 to bulge outward and undergo plastic deformation, ultimately forming a ring rib structure.

[0022] In this embodiment, the outer edge of the expansion block 404 is a circular arc-shaped protrusion. The curvature of the outer edge of the expansion block 404 matches the curvature of the inner wall of the ring rib of the metal barrel 5. The protrusions of multiple expansion blocks 404 can form an outer circle that matches the size of the ring rib.

[0023] In this embodiment, a first hydraulic cylinder 406 is fixedly mounted on the side of the mounting base 401 away from the mounting plate 402, and the output end of the first hydraulic cylinder 406 is fixedly connected to the mounting shaft 403. Figure 1 As shown, the first hydraulic cylinder 406 extends, causing the mounting shaft 403 to slide to the left, and multiple expansion blocks 404 expand outwards simultaneously. The first hydraulic cylinder 406 retracts, causing the mounting shaft 403 to slide to the right, and multiple expansion blocks 404 retract inwards simultaneously.

[0024] In this embodiment, the transmission mechanism 3 includes a base plate 301, which is fixedly connected to the side of the machine base 1. A slide rail 302 is fixedly provided on the base plate 301, and a slide table 303 is slidably connected on the slide rail 302. A mounting base 401 is fixedly provided on the slide table 303. A lead screw 304 is rotatably provided on the base plate 301. The lead screw 304 and the slide rail 302 are both parallel to the mounting shaft 403. The slide table 303 and the lead screw 304 are threadedly rotatably connected. A motor 305 is fixedly connected to the base plate 301. The output shaft of the motor 305 is fixedly connected to one end of the lead screw 304. The motor 305 drives the lead screw 304 to rotate, and the lead screw 304 drives the slide table 303 to move along the slide rail 302. This allows the expansion rib mechanism 4 to extend into different positions inside the metal barrel 5, and finally, ring rib structures are processed in different parts of the metal barrel 5.

[0025] In this embodiment, the conveying mechanism 2 includes a transmission chain 201 rotatably mounted on the base 1. The transmission chain 201 is equipped with multiple positioning fixtures 202 for clamping the metal bucket 5. A second hydraulic cylinder 203 is located above the transmission chain 201 and is fixedly connected to the base 1. A pressure plate 204 is fixedly connected to the output end of the second hydraulic cylinder 203. The pressure plate 204 engages with the outer surface of the metal bucket 5. Specifically, the pressure plate 204 has an arc-shaped notch that engages with the body of the metal bucket 5. When the second hydraulic cylinder 203 extends, it moves the pressure plate 204 downwards until it abuts against the surface of the metal bucket 5, preventing misalignment or displacement of the ring ribs caused by positional changes in the metal bucket 5 during processing. When the second hydraulic cylinder 203 retracts, it moves the pressure plate 204 upwards, disengaging the pressure plate 204 from the metal bucket 5.

[0026] In this embodiment, during use, the drive chain 201 drives the metal barrel 5. When the metal barrel 5 moves below the pressure plate 204, the drive chain 201 stops running, the second hydraulic cylinder 203 extends, and the pressure plate 204 moves downward and abuts against the body of the metal barrel 5 to prevent the metal barrel 5 from moving. Figure 3 As shown, motor 305 drives lead screw 304 to rotate, lead screw 304 drives slide 303 to move to the left, and causes expansion mechanism 4 to extend into different positions inside the metal barrel 5. First hydraulic cylinder 406 extends, causing mounting shaft 403 to slide to the left. Multiple expansion blocks 404 expand outwards simultaneously. The protruding ridges on the outer circumference of the multiple expansion blocks 404 cause the sidewall of metal barrel 5 to bulge outwards and undergo plastic deformation, ultimately forming ring ribs. Motor 305 reverses, lead screw 304 drives slide 303 to move to the right, causing expansion mechanism 4 to retract from inside the metal barrel 5. Second hydraulic cylinder 203 retracts, pressure plate 204 is lifted upwards, and transmission chain 201 continues to run. When the next metal barrel 5 moves below pressure plate 204, the above steps are repeated for continuous processing.

[0027] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
