[0002] During the production and transportation of steel barrels, they are prone to being bruised and deformed. Generally, the mouths of closed steel barrels are relatively small, and it is difficult to restore their shape. Therefore, after the steel barrels are damaged and deformed, they are all selected for scrap disposal.

[0048] Based on the low efficiency and poor effect of manually shaping the steel barrel 50, the embodiments of this specification propose a processing solution: as Figure 1 shown, a shaping structure for a steel barrel 50 of the present invention. The steel barrel 50 is placed on the support plate of the second support assembly 20. The first support plate 14 of the first support assembly 10 automatically presses the steel barrel 50 through the action of an oil cylinder. Compressed air is automatically filled into the steel barrel 50 through the air bag bearing 12 to tension the steel barrel 50. Under the action of the second telescopic member 44, the pressing roller assembly 40 automatically closes the protective plate 45 through the pressing rod 42, and the pressing roller 41 automatically presses the outer wall of the steel barrel 50. Bearings are installed at the centers of the pressing rollers of each pressing roller 41; after the motor of the transmission assembly 30 is automatically started, the steel barrel 50 and the three pressing rollers 41 move relative to each other along the outer wall of the steel barrel 50 for rolling. The protective plate 45 ensures the safety of the operator during the operation of the equipment, and finally completes the shaping and repair of the steel barrel 50.

[0049] The following describes the technical solutions provided in each embodiment of the present application with reference to the accompanying drawings.

[0050] As Figures 1 - 2 shown, a shaping structure for a steel barrel 50 provided by the present invention includes a first support assembly 10, a second support assembly 20, a transmission assembly 30, and a pressing roller assembly 40; the first support assembly 10 and the second support assembly 20 are correspondingly arranged, the pressing roller assembly 40 is arranged around the steel barrel 50, and the pressing roller 41 of the pressing roller assembly 40 can press the steel barrel 50.

[0051] Among them, the first support assembly 10 and the second support assembly 20 are arranged opposite to each other to clamp the steel barrel 50 and drive the steel barrel 50 to rotate.

[0052] Among them, both the first support assembly 10 and the second support assembly 20 are rotary support assemblies. For example, the first support assembly 10 can be an active rotary support assembly, and the second support assembly 20 can be a driven support assembly.

[0053] Among them, the support surface of the first support assembly 10 can be movably arranged to adapt to steel barrels 50 of different sizes or to facilitate the installation or removal of the steel barrel 50.

[0054] Among them, the transmission assembly 30 is used to drive a part of the first support assembly 10 to rotate, so as to rotate the steel barrel 50.

[0055] Among them, the pressure roller assembly 40 is located outside the steel barrel 50, and is used to press the steel barrel 50 and perform pressure rolling on the steel barrel 50 when the steel barrel 50 rotates.

[0056] Furthermore, the steel barrel 50 shaping structure further includes a frame. The first support assembly 10 is installed above the frame, the second support assembly 20 is installed below the frame, and the pressure roller assembly 40 is arranged on the side wall of the frame.

[0057] Specifically, after the steel barrel 50 is fixed between the first support assembly 10 and the second support assembly 20, the transmission assembly 30 drives a part of the first support assembly 10 to rotate. The first support assembly 10 drives the steel barrel 50 and the second support assembly 20 to rotate, so that the pressure roller assembly 40 performs roller pressing on the steel barrel 50.

[0058] As Figure 3 shown, the first support assembly 10 includes a first telescopic member 11, an air bag bearing 12, a support main shaft 13 and a first support disk 14; the telescopic shaft of the first telescopic member 11 is connected to the end of the support main shaft 13 through the air bag bearing 12. The support main shaft 13 is in transmission connection with the transmission assembly 30, and the transmission assembly 30 and the support main shaft 13 can move relative to each other. Among them, under the action of the air bag bearing 12, the transmission assembly 30 can drive the support main shaft 13 to rotate relative to the first telescopic member 11; one end of the support main shaft 13 away from the air bag bearing 12 is connected to the first support disk 14. After the first support disk 14 cooperates with the second support assembly 20 to fix the steel barrel 50, the gas conveyed into the air bag bearing 12 can enter the steel barrel 50 through the cavities inside the support main shaft 13 and the first support disk 14. The rotation of the first support disk 14 can drive the steel barrel 50 and the second support assembly 20 to rotate.

[0059] Among them, the first telescopic member 11 can be a telescopic structure such as a cylinder or an oil cylinder.

[0060] Among them, the first telescopic member 11 can be installed on the mounting frame, and the mounting frame is arranged at the top of the frame, so that the first telescopic member 11 is installed upside down on the mounting frame.

[0061] Among them, the mounting frame can be a portal structure, and the telescopic shaft of the first telescopic member 11 extends into the interior of the mounting frame and is connected to the air bag bearing 12.

[0062] Among them, the telescopic shaft of the first telescopic member 11 can be connected to the outer ring of the air bag bearing 12, and the inner ring of the air bag bearing 12 is connected to the support main shaft 13, so that when the support main shaft 13 rotates, it does not affect the first telescopic member 11.

[0063] Specifically, when the supporting main shaft 13 is driven by the transmission assembly 30 to rotate, under the action of the air bag bearing 12, the first telescopic member 11 is not affected by the rotation of the supporting main shaft 13 and can always remain stationary.

[0064] Among them, the supporting main shaft 13 can be drivingly connected to the transmission assembly 30 through structures such as a transmission belt.

[0065] Among them, one end of the supporting main shaft 13 is located inside the mounting frame, and the other end extends into the machine frame, so that the first supporting disc 14 is installed into the machine frame.

[0066] Among them, the supporting main shaft 13 has an internal cavity, and the internal cavity of the supporting main shaft 13 is connected to the air outlet of the air bag bearing 12, so that the gas transported into the air bag bearing 12 can enter the internal cavity of the supporting main shaft 13, and then enter the steel barrel 50 through the first supporting disc 14.

[0067] Among them, the first supporting disc 14 is mainly used for clamping and fixing one end of the steel barrel 50 with an inlet, and can enable the gas to enter the steel barrel 50 through the inlet of the steel barrel 50.

[0068] Specifically, when the steel barrel 50 is placed on the second supporting assembly 20, the telescopic shaft of the first telescopic member 11 extends outwards, and drives the air bag bearing 12, the supporting main shaft 13 and the first supporting disc 14 to approach the inlet end of the steel barrel 50, so that the first supporting disc 14 cooperates with the second supporting assembly 20 to fix the steel barrel 50; compressed gas is transported into the air bag bearing 12, and part of the gas can enter the supporting main shaft 13 and the first supporting disc 14, and finally enter the steel barrel 50 to tighten the steel barrel 50; finally, the transmission assembly 30 drives the supporting main shaft 13 to rotate, and the supporting main shaft 13 drives the steel barrel 50 to rotate through the first supporting disc 14, so that the roller pressing assembly 40 roller presses the tightened steel barrel 50.

[0069] The present invention dissociates the first telescopic member 11 and the supporting main shaft 13 by using the air bag bearing 12, and can input compressed air into the steel barrel 50. Compared with the existing steel barrel 50 structure, the structure is simpler, and the air bag bearing 12 is fully utilized. The present invention tightens the inside of the steel barrel 50 through the air bag bearing 12, and roller presses the inside of the steel barrel 50 through the roller pressing assembly 40, which also improves the shaping efficiency and shaping effect compared with manual shaping.

[0070] In some of the embodiments, the surface of the first supporting disc 14 facing the steel barrel 50 is a concave structure, so as to form a gas flow space after clamping the steel barrel 50, and reserve space for the upper and lower barrels, which is convenient for loading and unloading the barrels.

[0071] Among them, the first supporting disc 14 can be a trumpet-shaped structure.

[0072] In some of these embodiments, a sealing ring 15 is provided on the side of the first support disc 14 facing the steel drum 50. The sealing ring 15 is used to seal between the steel drum 50 and the first support disc 14 to prevent gas leakage in the gas flow space or prevent compressed gas in the steel drum 50 from leaking.

[0073] In some of these embodiments, external splines are provided on the outer periphery of the support main shaft 13; the transmission assembly 30 includes a first bearing seat 31 and a sprocket 32; the first bearing seat 31 is fixedly provided and sleeved on the support main shaft 13; the sprocket 32 is connected to the inner ring of the first bearing seat 31 and sleeved on the support main shaft 13. The inner wall of the sprocket 32 is provided with internal splines that mesh with the external splines, and the sprocket 32 is connected to the output shaft of the motor through a chain 33.

[0074] Among them, the first bearing seat 31 is fixed to the top of the frame and is used to support and enable the sprocket 32 to rotate.

[0075] Among them, the sprocket 32 is respectively meshed and connected with the chain 33 and the output shaft of the motor. Thus, when the output shaft of the motor rotates, the sprocket 32 is driven to rotate through the chain 33, and then the support main shaft 13 is driven to rotate.

[0076] In some of these embodiments, the second support structure includes a second bearing seat 21 and a second support disc 22 provided on the second bearing seat 21. The second support disc 22 is used to cooperate with the first support disc 14 to fix the steel drum 50.

[0077] Among them, the second support disc 22 can rotate on the bearing seat. Thus, when the second support disc 22 cooperates with the first support disc 14 to clamp and fix the steel drum 50, the second support disc 22 rotates with the steel drum 50.

[0078] In some of these embodiments, as Figures 4 - 5 shown, the pressure roller assembly 40 includes a pressure roller 41. The pressure roller 41 is arranged to press against the outer wall of the steel drum 50 and is used to shape the steel drum 50 when the steel drum 50 rotates.

[0079] Among them, there can be multiple pressure rollers 41, which are arranged longitudinally along the steel drum 50 to increase the pressure roller area.

[0080] Among them, the pressure roller 41 has a tendency to move towards the steel drum 50 to press against the steel drum 50 and shape the steel drum 50 when the steel drum 50 rotates.

[0081] For example, the pressure roller 41 presses against the steel drum 50 under the action of a spring through a U-shaped connecting arm.

[0082] Further, the pressing roller assembly 40 further includes a pressing rod 42 and a driven rod 43. Wherein, the first end of the pressing rod 42 has a tendency to move towards the steel barrel 50. When the pressing roller 41 shapes the steel barrel 50, the second end of the pressing rod 42 is fixed; the driven rod 43 is connected to the first end of the pressing rod 42, and the side of the driven rod 43 facing the steel barrel 50 is used to mount the pressing roller 41; wherein, after the second end of the pressing rod 42 is fixed, the pressing rod 42 drives the pressing roller 41 to press the steel barrel 50 through the driven rod 43.

[0083] Specifically, after the second end of the pressing rod 42 is fixed, the first end of the pressing rod 42 drives the driven rod 43 to press towards the side close to the steel barrel 50, so that the pressing roller 41 presses the steel barrel 50.

[0084] Wherein, the first end of the pressing rod 42 can have a tendency to move towards the steel barrel 50 under the action of a spring or other components.

[0085] Wherein, the outer side of the middle part of the driven rod 43 is connected to the pressing rod 42, and the inner side of the middle part of the driven rod 43 is connected with the pressing roller 41. When the position or inclination angle of the pressing rod 42 changes, the position of the driven rod 43 will move along with the pressing rod 42 to adjust the position of the pressing roller 41.

[0086] Further, the pressing roller assembly 40 further includes a second telescopic member 44. A connecting block is connected to the telescopic shaft of the second telescopic member 44, and the connecting block is connected to the second end of the driven rod 43 to drive the second end of the pressing rod 42 to move towards or away from the steel barrel 50.

[0087] Further, the second telescopic member 44 is fixed on the side wall of the frame, and the telescopic shaft of the second telescopic member 44 is supported by a slide rail fixed on the frame to realize the fixed support of the second telescopic member 44, and further support the pressing rod 42, the driven rod 43 and the pressing roller 41 through the second telescopic member 44.

[0088] Further, the pressing roller assembly 40 further includes a protection plate 45. The protection plate 45 is arranged at the end of the driven rod 43. When the second telescopic member 44 drives the second end of the driven rod 43 to move and change the position of the driven rod 43, the protection plate 45 can move along with the driven rod 43.

[0089] Wherein, when the second telescopic member 44 drives the second end of the pressing rod 42 to move away from or close to the steel barrel 50, the first end of the pressing rod 42 drives the position of the driven rod 43 to move, so that the driven rod 43 drives the protection plate 45 to move in front of the second telescopic member 44 to protect the staff.

[0090] In some of these embodiments, in each pressing roller assembly 40, there may be two pressing rods 42, which are arranged in a V-shape. There are also two driven rods 43 and two pressing roller wheels 41, which are correspondingly installed in the corresponding pressing rods 42 to increase the pressing roller efficiency for the steel drum 50.

[0091] In some of these embodiments, there are two pressing roller assemblies 40 to perform pressing roller operations on the steel drum 50 from both sides.

[0092] Specifically, in the standby state of the device, the telescopic shaft of the second telescopic member 44 retracts, causing the two protective plates 45 to move apart to both sides to place the shaped steel drum 50. After the device is started, the second telescopic member 44 drives the two protective plates 45 to approach each other through the pressing rod 42 and the driven rod 43 to protect the staff, and makes the pressing roller wheel 41 press against the outer surface of the steel drum 50. When the steel drum 50 rotates, the pressing roller wheel 41 presses against the surface of the steel drum 50 and cooperates with the tension force of the internal compressed air to perform roller pressing and shaping on the outer peripheral surface of the steel drum 50.

[0093] The working principle of the present invention is as follows:

[0094] The steel drum 50 to be shaped is placed on the second support disk 22 of the device. The first telescopic member 11 operates to lower the first support disk 14 to press the steel drum 50 tightly. The support main shaft 13 is a hollow structure, and the external spline designed on its outer surface cooperates with the internal spline of the sprocket 32 on the sprocket 32 and chain 33 mechanism to slide up and down.

[0095] A layer of rubber sealing ring 15 is fixed under the first support disk 14. After the first support disk 14 presses the steel drum 50 tightly, the first support disk 14 seals the barrel opening of the steel drum 50. The center of the first support disk 14 is a hollow structure to form an avoidance space, and the avoidance space is used to facilitate loading and unloading of the barrel. The second support disk 22 is a fixed non-driven turntable. In the standby state, the first support disk 14 is at the highest position. After the barrel loading is completed, the first telescopic member 11 operates, and through the spline effect, the first support disk 14 and the second support disk 22 clamp the steel drum 50. When the first support disk 14 and the steel drum 50 are pressed tightly, the airbag bearing 12 fills the inside of the steel drum 50 with compressed air through the center of the first support disk 14 under the control of an external solenoid valve to tension the steel drum 50.

[0096] Further, a compressed air pressure reducing valve is installed on the device to control the compressed air pressure at 0.5 - 0.6 MPa. The solenoid valve is opened to fill the compressed air into the steel drum 50. When the shaping is completed, the solenoid valve operates to switch, close the air inlet, and open the exhaust port. The compressed air inside the steel drum 50 is discharged through the silencer of the exhaust port.

[0097] After the upper barrel is completed, the protective plate 45 closes, and the 3-4 guard plate protects the operator's safety during the entire shaping process. The 3-5 pressure roller wheel 41 assembly presses against the outer wall of the steel barrel 50. The 6 driving motor is turned on, and the 4-1 first support disk 14 is driven through the 4-3 chain 33 and sprocket 32 assembly, driving the 2 lower support mechanism to rotate the steel barrel 50. Under the combined action of the tension of the internal compressed air and the pressure of the external roller mechanism, the circumferential surface of the steel barrel 50 is shaped.

[0098] In the steel barrel 50 shaping structure of the present invention, during the production process of shaping the steel barrel 50, automatic shaping of the steel barrel 50 is achieved. Compared with manual shaping, it has higher efficiency and better shaping effect. When shaping some severely damaged steel barrels 50, it performs even more excellently. Moreover, setting the steel barrel 50 shaping structure to be vertical also reduces its floor area and makes the operation more flexible.

[0099] In this specification, the same or similar parts among the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the product embodiments described later, since they correspond to the methods, the descriptions are relatively simple, and the relevant parts can be referred to the partial descriptions of the system embodiments.

[0100] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
