Abstract
The invention relates to an adjustable drawbench. A pull rod is installed in an outer sleeve and passes through an expansion inner hole to be connected with a screw thread at the left end of a connecting sleeve, wherein the expansion inner hole is provided with annular teeth on a left side outer circle and provided with a quartering slot to the middle part along an axes; the right end of an expansion tooth is connected with an inner sleeve sleeved on the outer wall of the pull rod by a thread screw; the inner sleeve is connected with a guide sleeve by a guide bolt; the guide sleeve is connected with an oil cylinder piston rod by a thread screw; and the middle part of the connecting sleeve is provided with a spring. The invention has the advantages of simple structure, reasonable design, convenient operation without damaging a tube plate, integrated elastic expansive sleeve type expansion tooth, reliable tube drawing operation, convenient reset, high degree of automation, time and labor saving and largely improved working efficiency. A hydraulic oil cylinder is adopted for providing powder, thereby the motion is stable, and the stress is uniform. A pull rod thread regulating mechanism can conveniently, rapidly and finely adjust the maximum expansion size.
Description
Technical field
The present invention relates to a kind of drawbench, especially relate to a kind of adjustable drawbench.
Background technology
At present, the bloated toothed portion of the related drawbench in this field is that split type pintongs combines, and wales by the tail springs steel wire.This structure is difficult for resetting after extracting pipe, and bite is in pipe easily.In addition, the maximum expansible size of expand tube can not be regulated, and to the caliber of the different margins of tolerance, needs to change the bloated tooth of different size.Influence very much efficiency of construction.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, easy to operate, quick, do not damage the adjustable drawbench of tube sheet.
In order to achieve the above object, the technical solution used in the present invention is: pull bar is housed in overcoat, pull bar penetrates the left side cylindrical annular tooth, and open quartering groove to the bloated tooth internal control and the adapter sleeve left end screw thread at middle part along axis and join, bloated tooth right-hand member position joins by screw thread and the interior cover that is socketed on the pull bar outer wall, interior cover joins by guider screw and guide pin bushing, and guide pin bushing links to each other with the oil cylinder piston bar by screw thread, and spring is equipped with at the adapter sleeve middle part.
Advantage of the present invention is:
Simple in structure, reasonable in design, easy to operate, do not damage tube sheet, the integral, flexible expansion sleeve type tooth that expands, tube drawing is reliable, is convenient to reset.Power adopts hydraulic jack, and motion is steadily, and is stressed even, the pull rod screw guiding mechanism, and fine-tuning maximum expansible size, convenient and swift.The automaticity height, time saving and energy saving, can increase work efficiency greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
As shown in Figure 1, pull bar 1 is equipped with in the present invention in overcoat 3, pull bar 1 penetrates the left side cylindrical annular tooth, and open quartering groove to 2 internal controls of bloated tooth and the adapter sleeve left end screw thread at middle part along axis and join, bloated tooth 2 right-hand member positions join by screw thread and the interior cover 4 that is socketed on pull bar 1 outer wall, interior cover 4 joins by guider screw 5 and guide pin bushing 7, and guide pin bushing 7 links to each other with oil cylinder 10 piston rods by screw thread, and spring 8 is equipped with at adapter sleeve 9 middle parts.
The present invention penetrates tooth 2 endoporus that expand by pull bar 1 and is threaded with adapter sleeve 9 left ends, and this screw thread not only plays the connection effect, can also determine the maximum expansible size of bloated tooth 2 by the length that the adjustment pull bar exposes.The screwing length of adjusting screw thread can be pulled out the pipe of different inner diameters tolerance.Bloated tooth 2 right-hand member positions join by screw thread and interior cover 4, and interior cover 4 links to each other with guide pin bushing 7 by guider screw 5.Guide pin bushing 7 joins with adapter sleeve 9 left end screw threads.Adapter sleeve 9 right-hand members are connected with oil cylinder 10 piston rods by screw thread, and spring 8 is equipped with at adapter sleeve 9 middle parts, make adapter sleeve 9 be in stress all the time, guarantee that pull bar 3 right-hand member screw threads are not loosening, and the tooth external diameter that expands does not change.Guide pin bushing 7 is slotted up and down, and guider screw 5 slides in groove.
Operating process of the present invention:
1, the tooth external diameter adjustment of expanding: open oil pump, pull bar 1 moves synchronously backward with guide pin bushing 7, to guide pin bushing 7 inner faces with stop after interior cover 4 left sides contact.Rotating rod 1 is adjusted tooth 2 external diameters to regulation (the different tube diameters tolerance required size) size that expands and is promptly finished.
2, tube drawing: wait to pull out in bloated mouthful in following bloated tooth 2 insertions of oil cylinder release situation, make overcoat 3 left sides near the tube sheet end face.Open oil pump, pull bar 1 moves synchronously backward with guide pin bushing 7, effect by pull bar 1 conical surface, bloated tooth 2 progressively tooth is clamp-oned tube wall, reach maximum after treating guide pin bushing 7 inner faces and interior cover 4 left sides contacting, continue pulling again, guide pin bushing 7 drives the tooth 2 that expands and outwards moves with pipe, make the pipe of the oral area position of expanding break away from the end tubesheet holes, promptly finish the tube drawing process.
3, withdraw from: after the oil pump release, under the effect of compression spring 6, pull bar 1, guide pin bushing 7 synchronous resets, the tooth 2 that expands shrinks, and can withdraw from.
