Abstract
The utility model relates to a stretch-bending former for metal, comprising base, tank, oil circuit control switch, movable chuck on one side of the base, a rotation table at the middle part of the base, transmission vertical-axle, auxiliary chuck installed on the table, a rack mechanism of tank installed on the other side of the base and the rotation of the table is forced by the transmission of the rack meshing a gear installed on the vertical-axle. The rack mechanism of tank comprises cylinders, pistons and piston-rods out of which the rack is extended. The overflow orifices on the both side of the oil chamber are connected to the 3-way overflow valve. Cost of production is chopped because of the replacement of gear mission by the rack mechanism, in addition, 3-way overflow valve fixed on the tank make the stretch-bending former more smoothly, more durable, better manufacturability and more convenient to maintain or install and the structure more simple.
Description
Technical field
The utility model relates to a kind of section bar process equipment, particularly a kind of shape stretch benders.
Background technology
Stretch benders be used for that manufacturing dimension is big, the process equipment of profile accuracy requirement height, shapes such as frame costal margin bar that bending radius is bigger.Existing stretch benders kind is more, structure is different.Common turntable stretch-bending machine mainly is made up of rotary table, drawing mechanism, side pressure mechanism three parts.Be equipped with on rotary table and mend the machine drawing structure, the rotation of rotary table is by Electric Machine Control, and the motion of drawing mechanism, side pressure mechanism and benefit machine drawing structure 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 rotary table table top is tangent, workbench rotates and makes workpiece abut on the mould gradually, side pressure this moment mechanism exerts pressure at the point of contact, drawing mechanism is followed workpiece motion s and is kept enough tensile forces, is convenient to component shaping.
China Patent No. 03114613.9 disclosed a kind of turntable stretch-bending machine of stretching one's arms, it is in order to solve in the prior art when all kinds of bool of processing, need purchase two kinds of stretch bending equipment of turntable stretch-bending machine and stretch-wrap bending machine, cause the fund waste, the deficiency of cost up, 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.It is said that it can process various types of stretch bending workpiece, has characteristics easy to operate, that structure is little, easy for installation, has realized dual-use.But above-mentioned prior art drives workbench by motor, and speed-changing gear box must be set, and acquisition expenses or processing charges are higher, causes the complete machine expense to strengthen, and structure is complicated, inconvenient Maintenance and Repair.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, easy, easy to maintenance, lower-cost shape stretch benders of making, to overcome weak point of the prior art.
A kind of shape stretch benders by this purpose design, comprise support, fuel tank and oil circuit gauge tap thereof, one side of support is provided with the stretching chuck, the middle part is provided with rotary table and transmission vertical shaft, workbench is provided with to mend and draws chuck, its architectural feature is that the opposite side of support is provided with the oil cylinder rackwork, and the gears engaged on tooth bar and the transmission vertical shaft is rotated with push work platform.
Described oil cylinder rackwork comprises cylinder body, piston and piston rod, and the tooth bar post is extended in the outer end of piston rod.
Described cylinder body oil-filled chamber two ends are provided with spout hole, and spout hole is connected with the threeway overflow valve.
The engagement place of described transmission vertical shaft wheel and rack is provided with the adjustable base and the rolling post of adjustable clearance.
The utility model adopts the oil cylinder rackwork to substitute speed-changing gear box, can reduce cost significantly, and oil cylinder is provided with the threeway overflow valve, makes transmission more steady, and prolong service life, and it is simple and reasonable, making is easy, installation and maintenance are convenient.
