Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of profile bending, in particular to a profile bending device. BACKGROUND

[0002] Profile refers to a solid straight bar profile formed by plastic processing of metal, having a certain cross-sectional shape and size. The profile is made of iron or steel and other materials with certain strength and toughness through processes such as rolling, extrusion, casting, etc. The profile includes hot-rolled profile, cold-bent profile, cold-rolled profile, cold-drawn profile, extruded profile, forged profile, hot-bent profile, welded profile and special rolled profile, etc. Profile bending machine is widely used in shipbuilding, petrochemical industry, aviation, water and electricity, decoration, and electrical machinery manufacturing industries. In the decoration industry, high-speed plate shearing machine is widely used, which can complete the production of stainless steel plates, doors and windows, and the decoration of some special places. In the electrical industry, the plate shearing machine can cut the plate into different sizes, and then the bending machine is used for further processing. For example, computer cases, electrical cabinets, refrigerator and air conditioner shells are all made in this way. In the kitchen and catering industry, various types and specifications of stainless steel kitchen utensils are then processed, such as welding and bending. In the wind communication industry, wind power poles, road lamp poles, communication tower poles, traffic signal poles, monitoring poles, etc. are bent. In the automobile and shipbuilding industry, large-scale numerical control hydraulic plate shearing machines are generally used to complete the shearing work of the plate, and then the plate is processed by welding and bending. In the aerospace industry, high-precision numerical control plate shearing machines are generally required, which are accurate and efficient.

In recent years, argon arc welding, especially manual tungsten electrode argon arc welding, has become an indispensable means in various metal structure welding, so the demand for argon arc welding workers in various parts of the country is increasing. In recent years, the mechanization and automation of argon arc welding have been greatly improved, and more and more numerical control factors have been developed, reaching a higher stage. The use of welding machine group 7 argon arc welding in the device is mainly because the argon arc welding arc burns stably, the heat is concentrated, the arc column temperature is high, the welding production efficiency is high, the heat affected zone is narrow, the stress, deformation and crack tendency of the welded part are small, the argon arc welding is a clear arc welding, the operation and observation are convenient, the electrode loss is small, the arc length is easy to maintain, and there is no flux and coating layer during welding, so it is easy to realize mechanization and automation.

[0035] The lifting plate 1001 of the lifting group 10 is the main platform, the platform plate 1002 mainly provides an operable platform for the bent profile, the two sides of the profile are fixed in the platform plate 1002 through the bearing 1001, the rotating seat 1004 and the auxiliary pressure wheel 1005, and the moving track of the two sides of the profile is fixed during the profile bending process, and the fixed block 1006 is on the lifting plate 1001, one side extends to the platform plate 1002, the fixed block 1006 is fixed and stable, and mainly provides the bending angle limiting action of the profile during the bending process.

The bending module 1204 needs long-term friction and is the main contact component for the profile bending material, so it is made of high-chromium metal material. High-chromium metal is an excellent anti-wear material that is particularly valued. It has much higher wear resistance than alloy steel, much higher toughness and strength than general white cast iron, and also has good high-temperature resistance and corrosion resistance. In addition, it is easy to produce and has moderate cost, and is known as one of the best anti-wear materials in the current era.

[0038] The cutter holder 1501 in the cutter group 15 is the main base, and the cutter group 15 is mainly arranged on the third layer plate 13. The movable plate 1504, the cutter rod 1505 and the cutter module 1506 are driven to move by the threaded column D1502 and the motor D1503. The cutter 1507 is inserted into the lower surface position of the cutter module, which is the main structure for making profile angle bending.

[0039] The device bottom plate 1 is the main bottom plate, and the upper surface is connected to the support 2, which is the main structure for connecting the second layer plate 1101 and the third layer plate 13, and is limited by the limiting bolt 17. The limiting bolt 17 is a hand-tightening bolt that can be quickly disassembled without the aid of tools. The threaded column A4 and the motor A5 mainly provide driving force for the lifting group 10, and the guide wheel 16 facilitates the mobility and usability of the whole device.

[0040] The electrical components in this article are connected to the L298N master controller and 220V mains electricity, and the master controller can control the conventional known devices such as computers.

[0041] In use, first, the profile is placed on the lifting group 10, the position of the auxiliary pressure wheel 1005 in the lifting group 10 is adjusted, the driving force of the lifting group 10 is provided by the motor A5 and the threaded column A4, the corner bend of the profile is cut off by the cutter group, the lifting group 10 is moved to the bending group 12 and the bending driving group 11 by the motor A5 and the threaded column A4, the profile is bent by driving the bending group 12 to run by the bending driving group 11, at this time, the profile has been bent, but it is too loose and cannot be directly used as a finished product, the lifting group 10 is moved to the position of the welding machine group 7 by the motor A5 and the threaded column A4, and the bent profile is argon arc welded by the welding machine lifting group 6 and the welding machine group 7, thereby completing the overall operation of the equipment.
