Abstract
A weld seam intricate edge electromagnetic appliance which can eliminate the intricate edge deformation of weld seam is composed of an electromagnetic sucker, a lever, a hydraulic jack. The utility model has no effect on the surface of work pieces and will not produce noise in the elimination of the intricate edge of the weld seam.
Description
Affiliated technical field
The utility model relates to a kind of orthopedic and positioner of correcting the weldment mismatching deformation, especially can overcome the radially welding seam misalignment electromagnetism rectifier of misalignment of the bigger thin-wall barrel of radius.
Technical background
As everyone knows, can produce radially misalignment in the cylindrical shell group in to assembling process, along with reducing of cylindrical shell wall thickness and barrel dliameter ratio, radially the mismatching deformation amount increases, and must take measures to be eliminated.What adopt on the engineering at present, is mechanical wedge type straightening method.When orthopedic, earlier a right angle rigid support is welded on the cylindrical shell, firmly squeezes into a drift then between another cylindrical shell and rigid support, the component that leans on the drift inclined-plane to bear is in vertical direction eliminated the misalignment of two cylindrical shells and is reached the requirement of assembling.This method is not only wasted a large amount of welding filling material, drift, reaches the right angle rigid support, has been increased production cost, but also has destroyed the drum surface quality, has increased labour intensity, has produced bigger noise, has worsened working environment.
Summary of the invention
In order to overcome the deficiency of existing welding seam misalignment straightening method, the utility model provides a kind of welding seam misalignment electromagnetism rectifier, this welding seam misalignment electromagnetism rectifier can not only be corrected welding seam misalignment distortion, and surface of the work is not had influence, and does not have material consumption, noiseless during work.
The technical scheme in the invention for solving the technical problem is: electromagnet, the exhausted magnetic isolating pad of rigidity, rigid lever are fixed forming one with the ring that is rigidly connected, in order to prevent that electromagnet from increasing leakage field, between electromagnetic core and rigid lever, increased the exhausted magnetic isolating pad of rigidity.When the electromagnet starting switch places enable position, produce bigger electromagnetic attraction between electromagnet and the workpiece, the two is just inhaled together firmly.Meanwhile, a hydraulic jack is housed between rigid lever and another welded part; Handle pressurization by hydraulic jack just can apply a power that makes progress to rigid lever by jack, workpiece is mentioned by rigid lever, the exhausted magnetic isolating pad of rigidity, electromagnet by this power.The height that workpiece is mentioned is by the lifting altitude control of hydraulic jack.When two welded parts surface is concordant, carry out tack welding.After the tack welding, after earlier the hydraulic jack release being restored, again the electromagnet starting switch is placed stop position, then electromagnet demagnetize immediately and and the suction between the workpiece disappear, electromagnet separates with workpiece, thereby finishes once-through operation.
The beneficial effects of the utility model are: when can eliminate welding seam misalignment, to workpiece surface quality do not have influence and do not have material consumption, reduced labour intensity, improved working environment, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical section structural map of an embodiment of the present utility model.
Fig. 2 is electromagnet magnetization, demagnetization circuit theory diagrams of the present utility model.
Among the figure, 1. workpiece, 2.E shape electromagnet, 3. solenoid, the 4. exhausted magnetic isolating pad of rigidity, 5. rigid lever, the ring that 6. is rigidly connected, 7. electromagnet casing, 8. workpiece, 9. jack, 10. oil cylinder, 11. handles, 12. help plug, 13. pressure heads, 14. release knobs.
The specific embodiment
In Fig. 1, be rigidly connected ring (6) fixing formation one and being encapsulated in the housing (7) of the exhausted magnetic isolating pad (4) of electromagnet (2), rigidity, lever (5) three.During work, connect the power switch HK among Fig. 2 earlier, again starting switch K is placed enable position; Power supply (+), current-limiting resistance RD1, RD2, starting switch K, normally closed interlock 2J
3, relay 1J, current-limiting resistance RD3, power supply () loop connect, relay 1J is charged, its normally open contact closure, and normally closed interlock disconnects; Then power supply (+), current-limiting resistance RD1,1J
1, resistance R
1, indicator lamp ZD, 1J
4, 1J
3, current-limiting resistance RD3, power supply (-) loop also connect, electromagnet coil (3) is charged, thus make the bigger electromagnetic attraction of generation between electromagnet (2) and the workpiece (1) and be pulled together securely form whole.Then hydraulic jack handle (11) is pressurizeed, liquid is squeezed in the oil cylinder (10), promotion helps on the plug (12) and moves, thereby lever (5) is applied a power vertically upward by pressure head (13), power is raised workpiece (1) by lever (5), the exhausted magnetic isolating pad (4) of rigidity, electromagnet (2) thus, reach with another workpiece (8) is surperficial and carry out tack welding when concordant, thereby realized eliminating the purpose of mismatching deformation.
Claims (3)
1. welding seam misalignment electromagnetism rectifier, this welding seam misalignment electromagnetism rectifier mainly is made up of magnechuck, rigidity pole, mechanical lifting device three parts such as (jack).It is characterized in that: magnechuck is connected with rigidity pole, and under the effect of electromagnetic attraction, magnechuck is connected with one of them workpiece again, and between rigidity pole and another workpiece, just can eliminate welding seam misalignment by the effect of mechanical lifting device.
2. welding seam misalignment electromagnetism rectifier according to claim 1 is characterized in that; Electromagnet, power supply reach and are linked in sequence into magnechuck towards demagnetization circuit, are rigidly connected after the exhausted magnetic isolating pad of rigidity between magnechuck and rigidity pole.
