The bending machine has the advantages of: simple structure, small size and light weight; low manufacturing cost, inexpensive manufacture and easy promotion; simple and convenient transportation, installation and operation, safety and reliability; and easy straightening to special cross sections or complicated special cross sections particularly, and meeting the requirements on machining of different cross-sectional areas and different materials, such as rolled steel, stainless steel, copper alloy and aluminum alloy.
Description
Technical field
The present invention relates to metallic conduit bending machinery technical field, a kind of specifically inner-tension deformation bender.
Background technology
Present metal folding adopts big machinery to add the method for mould more, and like punch press, large-sized hydraulic press etc., these mechanical volumes are big, heavy, floor space is big, power consumption is high, investment in fixed assets is big, carry out bending for long shaped steel and can't realize.
Summary of the invention
The objective of the invention is to develop a kind of simple in structure, handling ease, be utilized in the way that applies tension force in the metal material, make special-shaped metal material produce the inner-tension deformation bender of bending.
Inner-tension deformation bender of the present invention comprises: workbench, actuating unit, Bending Mould and electric control gear.
Workbench comprises: working plate links to each other with support.
Actuating unit comprises: motor and speed reducer links to each other, and reductor links to each other with wire reel, and the electric control gear of control motor rotation, all is contained on the support of workbench.
Bending Mould comprises: fixed half and moving half.Cover half is contained in the hole of working plate, and fastening with nut; Be installed with steel wire rope on the dynamic model, two of steel wire rope links to each other with steel wire rope buckle on twisting in cable drum.
The steel wire rope buckle links to each other with steel wire rope, and the other end is passed the guiding wheels and linked to each other with cable drum.
Bending Mould is changed different dies according to the number of times of bending.
Be equipped with on the bending cover half on backstay and the backstay fastening nut is arranged.
On the bending dynamic model lacing hole is arranged.
Have round on the working plate, be welded with the extension sleeve pipe under the round, the backstay on the bending cover half is contained in the round, and fastening with nut.
Electric control gear control actuating unit rotates.
Inner-tension deformation bender of the present invention is achieved in that with special-shaped metal material bending the backstay of bending cover half is contained in the round that has on the working plate, and fastening with nut, and then the bending cover half installs; On working plate, put the bending dynamic model; In the lacing hole of bending dynamic model, put on steel wire rope; Two of steel wire rope links to each other with steel wire rope buckle on twisting in cable drum, leans against the workpiece of wanting bending on the bending cover half, then starts transmission device; Dynamic model is drawn close to workpiece, until the requirement that reaches bending; If want bending repeatedly to become complex cross-sectional, then mold exchange more according to the method described above carries out repeatedly.
Transmission system:
Ac motor links to each other with cable drum with the helical teeth reductor of i=30 through i=2 deceleration belt pulley.On reel, be tied with the steel wire rope of two d=10mm.Steel wire rope reaches table top through guide wheel system, and the terminal of two steel wire ropes is the hooks that can conveniently connect and untie, and links into an integrated entity through this hook and work piece.During work, clamp mechanism is clamped after the workpiece, and transmission system tractive steel wire rope just forces direction the deform motion of workpiece towards regulation.
Electric-control system:
The native system core component is the shopin Series Frequency Converter of Shanghai Ou Pin electrical equipment company.This device is supplied power by the OPI9000A2.2/4 type.Frequency-variable electronic circuit, PLC Programmable Logic Controller and I/O interface are housed in frequency converter inside, on its panel, can easily system be programmed and running situation monitored.Frequency converter output frequency 0-400hz is adjustable continuously.Native system design output frequency is 0-50hz.System can set PID (ratio, integration, differential) control law easily, guarantees equipment steady operation under any rotating speed.System can send torque capacity under heavy duty, still can guarantee equipment safety operation up to stall.
System wiring figure and control method:
Native system wiring such as schematic diagram: its major loop 380V, the 50hz AC power is connected to the power end daughter board of control cabinet.Open (kk) through the sky that has short circuit and overload protection and be connected with line contactor (jcp), the output of line contactor, (R), (W, V U) through terminal board, are sent to traction motor (DJ) to the output of frequency converter for T, S to be connected to the input of frequency converter.
The control power supply connects the load-side of opening from sky, delivers to the terminal board of control cabinet through the 5A protector.The red light indication has electricity, green light indication line work.
Three-position switch k1 on the operation panel links to each other with the RST lead-out terminal with the FOR of frequency converter through shielded cable." RUN " and " resetting " with its control system.Release knob is when the centre position, and system quits work.K2 and rev and spl join, with its control system inversion and low speed.K3 and sph and spm join.Potentiometer on the operation panel (dwq) is the analog quantity input of system, and its three terminals are received vr, vl, acm.The position of its medial head is corresponding with the output frequency of system or rotating speed.When system moves, need only the turn potentiometer, just can change the duty of system easily.
Pay special attention to: during wiring, " E " of frequency converter end (ground terminal) is ground connection not! The DCM common port of the I/O control end of frequency converter could not have any contact with the zero line of AC power! The fin of frequency converter, with insulate " zero "!
The advantage of inner-tension deformation bender of the present invention is: simple in structure, volume is little, and is in light weight; Low cost of manufacture, inexpensive is easy to promote; Transportation, installation, simple to operation, safe and reliable; Particularly special-shaped section or very complicated special-shaped section are carried out the bending ratio and be easier to, adapt to the needs of different cross-sectional, unlike material processing, like steel, stainless steel, copper alloy, aluminium alloy etc.
