Abstract
The utility model relates to a pipe bender, which is characterized by mainly consisting of a framework, an oil cylinder, a rotary crank, an arc fixed pulley, a roller and a fixed support. The fixed support is fixed on the top of a worktable of the framework, the arc fixed pulley is in pin joint with the fixed support, the front of the rotary crank is in pin joint with the arc fixed pulley coaxially, the roller is in pin joint with the rotary crank and on the same axis with the arc fixed pulley, the rear end of the rotary crank is in pin joint with a piston rod of the oil cylinder, the oil cylinder is fixedly connected with the worktable of the framework, and a stopper is arranged on the top of the worktable of the framework parallel to the axis of the piston rod of the oil cylinder. The pipe bender has the advantages that the pipe bender can bend pipes in an arc cold manner along a fixed arc clamping fixture by utilizing the oil cylinder as propelling force and can be placed on a construction site or a rivet welding workshop to bend pipes conveniently at any time and anywhere according to required angles.
Description
Technical field
The utility model belongs to bending machine, relates in particular to a kind of bending machine that adopts oil cylinder to make the circular arc cold bend(ing) as propulsion power, along fixing circular arc mold.
Background technology
In the building site that much needs bent tube technique, and rivet welding factory, common way is that the factory that large quantities of steel pipes that need simmering and bending are delivered to angle pipe equipment is processed.So often running into arc angle has error, causes difficulty to field Welding, revises also pretty troublesome.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of bending machine to be provided, and volume is little, simple in structure, can be placed on building site or rivet welding workshop whenever and wherever possible, easily carries out bend pipe according to needed angle.
The utility model is realized a kind of bending machine for realizing above-mentioned purpose through following technical scheme; It is characterized in that: mainly constitute by frame, oil cylinder, block, rotating crank, circular arc fixed wheel, running roller and fixed support; Be fixed with fixed support on the said frame work top, be connected with the circular arc fixed wheel on the fixed support, said rotating crank front end and the coaxial pin joint of circular arc fixed wheel; Be connected with running roller on the rotating crank with on the same axis of circular arc fixed wheel; Said rotating crank rear end and oil cylinder piston lever pin connect, and oil cylinder and frame work top are affixed, are provided with block with oil cylinder piston rod axis parallel position on the frame work top.
Beneficial effect: adopt oil cylinder to make the circular arc cold bend(ing) as propulsion power, the fixing circular arc mold in edge.Can be placed on building site or rivet welding workshop whenever and wherever possible, easily carry out bend pipe according to needed angle.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the circular arc fixed wheel is fixed on partial view on the frame work top.
1-oil cylinder among the figure, 2-steel pipe, 3, the 5-block, 4-rotating crank, 6-circular arc fixed wheel, 7-running roller, 8-fixed support, 9-frame.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of bending machine; Mainly constitute by frame 9, oil cylinder 1, block 3,5, rotating crank 4, circular arc fixed wheel 6, running roller 7 and fixed support 8; Be fixed with fixed support on the said frame work top, be connected with the circular arc fixed wheel on the fixed support, said rotating crank front end and the coaxial pin joint of circular arc fixed wheel; Be connected with running roller on the rotating crank with on the same axis of circular arc fixed wheel; Said rotating crank rear end and oil cylinder piston lever pin connect, and oil cylinder and frame work top are affixed, are provided with block with oil cylinder piston rod axis parallel position on the frame work top.
Operation principle:
Can change the diameter of wheel circular arc fixed wheel 6 according to the size of required circular arc.Size according to diameter of steel tube is changed wheel circular arc fixed wheel and running roller, makes its semicircle groove width corresponding.Steel pipe 2 is placed in two half slots, is close to block 3,5.Oil cylinder throw crank, crank are center of circle driven wheel 7 with A, do circular motion.Under the push effect of wheel 7, make steel pipe do bend tension along the circle of circular arc fixed wheel, the size of angle is by artificial control.The distance that crank A, B are 2 is decided by setting steel pipe arc radius and diameter of steel tube, according to the difference of bending diameter, can change corresponding crank at any time and get final product.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
