Description

Technical Field

[0001] The invention relates to a container flanging device. Background Art

[0002] Container manufacturing is a common project in the non-standard equipment processing industry. It has developed into a mature process flow and is used by many processing industries. However, some oversized container workpieces need to be flanging. For example, some industries (such as medicine and food) require a jacketed container with a complete closed pressure chamber on the surface of an ordinary container due to production process requirements. The workpiece has a special structure and a large size, which makes processing more difficult.

[0003] One of the traditional flanging technology construction methods:

[0004] Heating bending technology: add arc support at the bending point of the flanged workpiece and temporarily fix it. Use oxygen-acetylene flame evenly distributed on the circumference of the flanged workpiece for heating treatment. After reducing the hardness of the workpiece, manual bending and manual hammering are used. This method has the following disadvantages in processing products:

[0005] (1) Due to uneven force during manual hammering, the conical seal has aggregated wrinkles, which affects the assembly and welding quality with the inner tube;

[0006] (2) This method is only suitable for flanging thinner plate parts. It is difficult to achieve flanging of large workpieces using this method.

[0007] (3) The labor intensity is high and the work efficiency is extremely low.

[0008] Traditional flanging technology construction method 2:

[0009] Heating and stamping technology: Cut the material into pieces according to the diameter and length of the jacket cylinder, and then stamp it in pieces. Each piece of material is stamped to meet the arc, flange length and angle required by the drawing before assembly. Layout pre-assembly must be performed before assembly, and the weld at the assembly position should avoid the opening of the equipment pipe. Disadvantages of this method:

[0010] (1) The jacketed container is assembled in pieces, and the ovality of the cylinder has a large deviation, causing deformation of the pressure cavity;

[0011] (2) Cutting materials in pieces increases the loss of main materials and the amount of welding work, which is not conducive to energy saving. Summary of the invention

[0012] The purpose of the present invention is to provide a container flanging device, which can replace the manual heating and hammering methods to manufacture the flanging of super-large container workpieces, thereby solving technical problems such as low flanging curvature accuracy, high labor intensity, extremely low work efficiency, large material loss, and low safety.

[0013] The above purpose is achieved through the following technical solutions:

[0014] A container flanging device, which comprises: a support system, a rolling system, a pushing system and a control system. The support system is composed of a support base, a head support frame and a tail support frame. The head support frame and the tail support frame are connected with three working rollers on the rolling system, wherein the head support frame is welded by seamless rectangular steel pipes to form an integral frame, which is fixed just above the transverse support beam at the front end of the support base. The tail support frame is composed of upper and lower structural components, wherein the upper component is a detachable tipping frame, which is welded in the long direction of double-channel steel butt joints, and the flanging cylinder can be loaded and unloaded at this position after being laid down; the rolling system is composed of a motor, a reducer, three working rollers and a lifting device for the upper roller, wherein the three working rollers are symmetrically arranged in a herringbone shape, and the two lower rollers are installed in the bearings of the head support frame and the tail support frame as active rollers, The upper roller is arranged as a driven roller in a symmetrical position between the two lower rollers, and is installed in a bearing that can move vertically between the component head support frame and the tail support frame, and the front end of the upper roller is a conical structure; the processing cylinder is arranged between the two lower rollers and the upper roller, and the rotation of the two lower rollers drives the processing cylinder to rotate, wherein the upper roller presses down the processing cylinder through the lifting device; the jacking system is composed of a hydraulic jacking mechanism, a hydraulic pushing mechanism, and a supporting tie beam, and the hydraulic jacking mechanism is arranged directly below the end of the upper roller, and is a combination of a round steel pipe and a connecting rib plate and a jacking hydraulic cylinder body, which are welded and bolted to the crossbeam of the supporting base, wherein the top of the jacking hydraulic cylinder body is an arc-shaped structure, and the jacking hydraulic cylinder body structure is fixed at an angle of 30° to ensure the jacking force The direction is obliquely upward, so that it produces an angled flanging effect; the hydraulic pushing mechanism is composed of a slide guide rail, a roller bracket, a roller and a hydraulic cylinder body. The roller bracket is arranged on the slide guide rail of the longitudinal beams at both ends of the tail of the supporting base, and the roller brackets at both ends are installed with a relative inward tilt of 45° to meet the pushing effect of cylinders with different diameters; while the processing cylinder is driven to rotate by the two lower rollers, it is pressed down by the upper roller, the hydraulic lifting mechanism's lifting hydraulic cylinder lifts the flanging position of the processing cylinder, and the roller of the hydraulic pushing mechanism pushes the tail of the processing cylinder horizontally to form the flanging of the processing cylinder; the control cabinet of the electric control system is connected to each drive device through a control cable and a drive cable.

[0015] The container flanging device, the supporting base of the supporting system is formed by a pair of 300*180*8mm seamless rectangular steel pipes, the head supporting frame is welded by 300*180*8mm seamless rectangular steel pipes to form an overall frame, which is a non-detachable component, the lower structure of the tail supporting frame is a 300*180*8mm seamless rectangular steel pipe fixed directly above the crossbeam of the rear end supporting base, which is a non-detachable component, and steel plates are welded at the connection between the upper and lower structures and bolts are used to lock them front and back to avoid string movement during operation of the device.

[0016] The container flanging device has an outer diameter of 180 mm for the lower roller and a shaft end diameter of 100 mm. The Y160M-4 three-phase asynchronous motor is connected to the reducer by a V-belt for one-stage speed reduction. The reducer uses a cylindrical output gear and the two lower roller spur teeth to engage with each other for two-stage speed reduction, and ensures that the two lower rollers run in the same direction and at the same speed. The outer diameter of the upper roller is 300 mm. Since the end of the upper roller is a conical structure, it can ensure that there is enough distance between the upper roller shaft end and the lower roller shaft end to meet the space distance required for flanging.

[0017] The container flanging device described herein, the control system described herein is divided into an electric control system and a hydraulic control system, wherein the PLC controller, frequency converter, air switch, contactor, relay, switching power supply and other control components are all installed inside the industrial control cabinet, which can realize the forward and reverse rotation of the active shaft and the output of the hydraulic oil pump, and the hydraulic system described herein is an external integrated high-pressure hydraulic station, which can control three hydraulic systems of the hydraulic pushing mechanism, the hydraulic lifting mechanism and the upper roller adjustment mechanism through various oil pipes, reversing valves and other auxiliary parts.

[0018] The beneficial effects achieved by the present invention are:

[0019] 1. The present invention uses electric and hydraulic systems to work together, and the electric rolling drives the workpiece to rotate at a constant speed. The edge of the workpiece cylinder is lifted by the hydraulic round-head roller, so that the workpiece gradually forms a curved cone, which is safe and reliable.

[0020] 2. The present invention is suitable for flanging of super-large workpieces, and solves the cold flanging processing technology of thick plates and large workpieces. It can be used for flanging of carbon steel or stainless steel cylinders with a diameter range of 800mm-2400mm, a steel plate thickness of 6mm-12mm, and a flanging width of 100-200mm. The flanging effect is good, breaking through the forming processing technology of tile buckling, heating and rolling, maintaining the stability of the metallographic structure of the raw materials, while improving production efficiency and reducing the consumption of heating gas source, thereby saving energy.

[0021] 3. The present invention adopts multiple driving modes. The rotating parts of the equipment are electrically driven, and the transmission parts are hydraulically driven. The design mode combining the two power sources can not only meet the power requirements of workpiece flanging, but also maintain the smooth adjustment of the jacking and boosting mechanisms, and can achieve stepless speed regulation.

[0022] 4. The present invention has the characteristics of high safety, the hydraulic transmission has strong controllability in adjusting the telescopic amount and direction, and the direction change is easy. When an emergency occurs, no major impact will occur.

[0023] 5. The present invention adopts the flanging equipment to ensure that the flanging length of the cylinder circumference is consistent, the processing angle and arc are highly accurate, and the quality defects such as dead angles and wrinkles caused by rolling during the processing can be effectively suppressed.

[0024] 6. The present invention has the following structural features:

[0025] (1) Support system:

[0026] The supporting base is formed by a pair of 300*180*8mm seamless rectangular steel pipes, and its longitudinal and transverse support beams have the functions of bearing load and overall balance and stability.

[0027] The head support frame is an integral frame formed by welding seamless rectangular steel pipes, fixed just above the transverse support beam at the front end of the support base, and is a non-detachable component. The tail support frame is designed as an upper and lower structural component, and the upper component is a detachable tipping frame. It is welded in the long direction of double-channel steel butt joints, and the flanged cylinder can be loaded and unloaded at this position after being laid down.

[0028] The lower structure is a seamless rectangular steel pipe fixed to the top of the rear support base beam and is a non-detachable component. The upper and lower structures are connected by welding steel plates and locked with bolts to prevent the device from moving during operation.

[0029] The head support frame and the tail support frame are used to jointly support the dynamic and static loads generated by the driving wheel and the driven wheel of the transmission system. The dynamic load is the load generated by the operation of the driving wheel and the driven wheel, and the static load is the deadweight of the driving wheel, the driven wheel and the flanged parts.

[0030] (2) Rolling system:

[0031] The two lower rollers of the rolling system are active rollers, and are connected to the reducer by a Y160M-4 three-phase asynchronous motor with a V-belt for a first-stage speed reduction. The whole machine uses a cylindrical output gear and the two lower rollers' spur teeth to engage with each other for a second-stage speed reduction, and ensures that the two lower rollers run in the same direction and speed. The lower roller drives the roller wheel through an electric drive, and then drives the flanged cylinder to rotate at a uniform speed based on the friction principle, forming the overall flange of the processed parts.

[0032] The upper roller is set as a driven roller in a symmetrical position between the two lower rollers to ensure that there is enough distance between the upper roller shaft end and the lower roller shaft end to meet the required space distance for flanging. The upper roller is controlled by a hydraulic piston-piston hydraulic cylinder. First, the roller can be moved vertically up and down to realize the flanging of cylinders with different diameters. Second, it also has the function of pressing down to move the flanging cylinder upward. In addition, the designed spherical bearing can facilitate the tilting of one end of the upper roller, which is convenient for the loading and unloading process of the cylinder to be turned.

[0033] (3) Push system

[0034] The jacking system is composed of a hydraulic jacking mechanism, a hydraulic pushing mechanism, and a supporting tie beam. It is the core component for realizing the flanging technology and is the action unit for jacking the cylinder to flanging.

[0035] The hydraulic jacking mechanism is set just below the end of the driven roller. It is welded with a round steel pipe and a connecting rib plate and a hydraulic cylinder body and bolted to the crossbeam of the supporting base to ensure its firmness. The hydraulic jacking mechanism uses the hydraulic pressure of the rodless chamber to push the edge of the cylinder upward, and cooperates with the upper roller that presses the cylinder downward to gradually form a flanging effect. The hydraulic jacking mechanism is fixed at a slightly inclined angle of about 30° to ensure that the direction of the jacking force is obliquely upward, so that it produces an angled flanging effect.

[0036] The hydraulic pushing mechanism is mainly composed of a slide guide rail, a roller bracket, a roller and a hydraulic cylinder. The roller bracket is arranged on the sliding guide rails of the longitudinal beams at both ends of the tail of the tooling equipment, and the roller brackets at both ends are installed with a relative inward tilt of 45° to meet the pushing effect of cylinders with different diameters.

[0037] As the flanging angle of the processed cylinder increases, the length of the cylinder gradually decreases. The roller mechanism cooperates with the sliding guide rail through the hydraulic system to drive the roller to push the edge of the cylinder to limit the workpiece. In addition, one end of the hydraulic system is connected to the crossbeam of the roller bracket, and the other end is connected to the supporting tie beam to ensure that the direction of the rollers at both ends pushing the two sides of the cylinder is consistent with the thrust, so as to control the torsion of the cylinder.

[0038] (4) Control system:

[0039] The control system is divided into electric control and hydraulic control. The electrical control cabinet of the electric control system is connected to each drive device through control cables and drive cables. PLC controller, inverter, air switch, contactor, relay, switching power supply and other control components are installed inside the industrial control cabinet, which can realize the forward and reverse rotation of the active shaft and the output of the hydraulic oil pump.

[0040] The hydraulic system is an external integrated high-pressure hydraulic station, which can control three hydraulic systems including the pushing mechanism, the lifting mechanism and the upper roller adjustment mechanism through various oil pipes, reversing valves and other auxiliary parts.
