The invention relates to an inner tension deformation special section bending machine, comprising a working platform, a power drive, a die and a press bending device. The bending machine has the advantages of simple structure, compact size, light weight, low manufacturing cost, easy popularization, simple and convenient transportation, assembly and operation, safety and reliability. The bending machine is especially suitable for bending special sections or very complicated special sections, thereby being suitable in different cross sections and different materials, such as steel, stainless steel, copper alloy and aluminum alloy.
Description
Technical field
The present invention relates to metal material bending machinery technical field, a kind of specifically internal tension force deformation special-shaped section simmer bending machine.
Background technology
Traditional simmering and bending equipment, without exception all be that work piece one end is fixed, continuous apply external force, thereby make work piece produce distortion above the yield limit of work piece at deformation point, determine its shape by mould.If the section configuration complexity of work piece, sectional area is bigger, then needs complicated mould and powerful power.General this simmering and bending process equipment is a huge monster, costs an arm and a leg, and processing charges are very high, and yield rate is lower.Crooked manual bending of employing of metallic conduit now and mechanical bent way, no matter be manual bending or mechanical bend, all be to adopt the way of mould pushing to finish the bending of metal material, if special-shaped metal material, crooked so just difficulty more, the perhaps special-shaped metal material of some complexity bending of at all having no idea.
Summary of the invention
The objective of the invention is to develop a kind of simple in structure, handling ease, utilization apply tension force in metal material way, make special-shaped metal material produce the internal tension force deformation special-shaped section simmer bending machine of distortion.
Internal tension force deformation special-shaped section simmer bending machine of the present invention comprises: workbench, actuating unit and mould, bending press.
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 control device of control motor rotation, all is contained on the support of workbench.
Mould, bending press comprise: mould, and the backstay of mould is contained in the hole of working plate, and fastening with nut; One on steel wire rope is fixed on the wire reel, and the other end is passed the guiding wheels and linked to each other with buckle, and the power set startup afterwards that links to each other with buckle of two steel wire ropes makes workpiece stressed, makes the workpiece bending according to the radius of curvature of mould.
Have the round 2 of different curvature radius on the working plate, round is welded with for 2 times and extends sleeve pipe 3.
Be equipped with on the mould on backstay and the backstay fastening nut is arranged.
Electric control gear control actuating unit rotates.
Special-shaped metal material bending is achieved in that the round 2 that has different curvature radius on the working plate, the backstay that loads a die in the round 2 of a kind of radius of curvature as requested, and tightening nuts, then mould installs.Be close to mutually at the mid point of mould mid point with the special-shaped metal material that needs processing, steel wire rope through in the special-shaped metal material, and steel wire rope two is linked to each other with buckle, at this moment, can start motor, tighten up steel wire rope,, reach the requirement of bending at last with regard to forcing the direction motion that deforms of workpiece towards regulation.
Mould is an one-side mould, and the metal material of pipe, square tube, the better simply metal material in cross section or cross section complexity all is suitable for.
Transmission system:
Ac motor links to each other with cable drum with the helical teeth reductor of i=30 by i=2 deceleration belt pulley.On reel, be tied with the steel wire rope of two d=10mm.Steel wire rope reaches table top by 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 by 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 by the power supply of OPI9000A2.2/4 type (can select motor and frequency converter model according to work piece material and section).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 be 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 by 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 counter-rotating 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 internal tension force deformation special-shaped section simmer bending machine of the present invention is: simple in structure, volume is little, and is in light weight; Low cost of manufacture, low cost 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 bend ratio and be easier to, adapt to the needs of different cross-sectional, unlike material processing, as steel, stainless steel, copper alloy, aluminium alloy etc.
