Description
(1) technical field:
The present invention relates to field of machining, specifically a kind of product moulding equipment.
(2) background technology:
Stretch benders are that to be used for manufacturing dimension big, and the profile accuracy requirement is higher, and variable curvature extruding and the curved material bool of plate that relative bending radius is big are the essential equipment of section bar part production such as frame costal margin bar.At present, the equipment that is used for the section bar stretch bending both at home and abroad mainly contains two kinds: turntable stretch-bending machine and stretch-wrap bending machine.
Turntable stretch-bending machine mainly is made up of turntable, stretching device, side-pressing device three parts, and the benefit drawing device is housed on its intermediate station, and the rotation of turntable is by Electric Machine Control, and the motion of stretching device, side-pressing device and benefit drawing device etc. is by HYDRAULIC CONTROL SYSTEM.In the process, the workpiece two ends draw chuck and stretching chuck to fix by benefit, mould on the edge of work and the turntable table top is tangent, turntable rotates and makes workpiece abut on the mould gradually, this moment, side-pressing device applied lateral pressure at the point of contact, stretching device is followed workpiece motion s and is kept enough tensile forces, is convenient to component shaping.Turntable stretch-bending machine is mainly used in crooked medium and small part, can finish the shaping work as peculiar parts such as annular, U-shaped, ellipse, spirality, S shape, variable inclinations.
The stretch-wrap bending machine mainly is made up of two devices of stretching one's arms, square workbench and lathe bed, and whole motions is all by HYDRAULIC CONTROL SYSTEM.In the process, the workpiece two ends are fixed by the stretching chuck that is contained in the stretching cylinder top on stretching one's arms respectively, and edge and mould in the middle of the workpiece are tangent, twoly stretch one's arms that being flapped toward moves abuts on the mould workpiece gradually, can be shaped.The stretch-wrap bending machine is easy to realize big tensile force, is fit to crooked heavy parts, and arc length can reach 6-9 rice, such as parts such as long purlin, rib, curtain wall muscle.
At present, factory will process all kinds bool, need purchase two kinds of stretch bending equipment of turntable stretch-bending machine and stretch-wrap bending machine, has increased production cost, and has occupied very big factory building space, has increased additional investment.
(3) summary of the invention:
In order to solve in the prior art, when all kinds of bool of processing, need purchase turntable stretch-bending machine and two kinds of stretch bending equipment of stretch-wrap bending machine, cause fund waste, the deficiency of cost up, the present invention to propose a kind ofly to collect turntable stretch-bending machine and stretch-wrap bending machine function is the stretch benders of one.
The invention is characterized in the turntable of turntable stretch-bending machine, lathe bed, the device of stretching one's arms of benefit drawing device, side-pressing device and stretch-wrap bending machine are combined, and when the right side stretch one's arms be fixed motionless during as stretching device, side-pressing device is formed turntable stretch-bending machine near turntable jointly with benefit drawing device, turntable; When side-pressing device left turntable, the turntable table top is fixed on became workbench on the abutment body, stretched one's arms and drive power and disconnect in the right side, and stretching one's arms with a left side drives and be flapped toward motion by the stretching support arm together, composition stretch-wrap bending machine.
So just constitute the turntable stretch-bending machine of stretching one's arms, promptly realized purpose of the present invention.
In the present invention:
Turntable.Turntable is made up of table top and abutment body, and abutment body is a cylindrical shape, with the lathe bed link position opening is arranged; There are fixed head and vertical shaft in the middle part in the abutment body, and the table top of turntable is installed on the vertical shaft, and mesa edge is equipped with the benefit drawing device; The outer and arranged on left and right sides of abutment body has the left and right lug of stretching one's arms of connection.The lathe bed front end is connected with the turntable abutment body, and end is equipped with the stretching support arm; For avoiding structural instability, lathe bed two wallboards run through abutment body, and between lathe bed two wallboards gripper shoe are arranged; The pin-and-hole that corresponding fixed mesa is arranged on abutment body and the table top.
Two devices of stretching one's arms.The a left side same prior art of stretching one's arms among the present invention.Stretching one's arms in the right side has turn-screw in the arm chamber, and an end of this turn-screw stretches out the end face of stretching one's arms, and a pair of vertical mutually conical gear that cooperates is installed on the top, and links with dynamical system.The ram below is for having the projection of tapped through hole, and projection is sleeved on the driving wire cylinder.The right side annulus that terminal two bottom sides has the fixing right side to stretch one's arms respectively of stretching one's arms.A left and right end of stretching one's arms is installed in turntable abutment body and arranged on left and right sides respectively by connecting lug, and the middle part is connected with the stretching support arm.For the stretch bending mould that adapts to various height and the processing of spiral workpiece, left and right stretching chuck of stretching one's arms is also for lift.
Transmission system.Transmission system of the present invention is made up of master gear, pinion, power transmission shaft, gearbox and motor.Gearbox and motor place underground, and master gear, pinion and power transmission shaft are positioned at turntable table top below.
Side-pressing device.The same prior art of the structure of side-pressing device, it installs the slide rail form that adopts, and promptly lays slide rail at the abutment body front end, and side-pressing device is installed on it.It between side-pressing device and the lathe bed right angle.
The invention has the beneficial effects as follows that dual-use can be processed various types of stretch bending workpiece, compare with two original equipment, reduced by a cover stretching device, reduced equipment manufacturing cost, thereby saved equipment purchasing fund and installing space, delicate structure, easy for installation, operation is easily gone.
