The manual deep-hole pipe cutter has the advantages of simple structure, low cost, strong adaptability, high pipe-cutting efficiency and thoroughness in pipe cutting and can be convenient for manually finishing the pipe-cutting operation of a deep-hole pipe end.
Description
Technical field
The present invention relates to a kind of stroke of pipe cutter, be specifically related to a kind of manual deep hole and draw pipe cutter.
Background technology
It is the specific purpose tool realizing the damaged heat exchanger tube of heat exchanger spot replace that manual deep hole draws pipe cutter.In heat exchanger, the medium of flowing often has the characteristics such as high temperature, high pressure, high flow rate, severe corrosive or strong permeability; And when structure Design and Calculation heat exchanger tube wall thickness, do not calculate again corrosion allowance; And in order to improve heat exchange property, the wall thickness of heat exchanger tube is often very thin, after longtime running, pipe wall of heat exchange pipe is corrosion failure under the effect of medium easily, causes the faults such as leakage.
When the heat exchanger tube of heat exchanger is damaged, simple method is blocked by heat exchanger tube.If the heat exchanger tube negligible amounts of the average every tube side of heat exchanger, block the heat exchange property that one or more heat exchanger tubes significantly can reduce heat exchanger.And if heat exchange equipment field condition is poor, when not having electronic, pneumatic or other instruments, a special hand-operated tools is just needed to realize the pipe work of drawing of deep hole pipe end to change damaged heat exchanger tube.
Summary of the invention
The object of the invention is for solving above-mentioned deficiency, provide a kind of structure simple, with low cost, draw tube efficiency high, draw pipe thoroughly and the special manual deep hole manually completed can be facilitated to draw pipe cutter.
The object of the invention is to be achieved through the following technical solutions: a kind of manual deep hole draws pipe cutter, comprise knife bar, eye bolt, plug plate, bearing, draw pipe cutter, tubesheet holes and holding screw, eye bolt is inserted in the hole of plug plate, knife bar is inserted in eye bolt, bearing is connected with the left end of eye bolt, and knife bar is connected with bearing, and the left end of knife bar is provided with draws pipe cutter, drawing pipe cutter is inserted in tubesheet holes, and holding screw is connected with a stroke pipe cutter.
The present invention has effect useful as follows: structure is simple, with low cost, strong adaptability, stroke tube efficiency are high, draw pipe thoroughly also can facilitate stroke pipe operation manually completed deep hole pipe end.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
As shown in Figure 1, a kind of manual deep hole draws pipe cutter, comprise knife bar 1, eye bolt 2, plug plate 3, bearing 4, draw pipe cutter 5, tubesheet holes 6 and holding screw 7, it is characterized in that: eye bolt 2 is inserted in the hole of plug plate 3, knife bar 1 is inserted in eye bolt 2, and bearing 4 is connected with the left end of eye bolt 2, knife bar 1 is connected with bearing 4, the left end of knife bar 1 is provided with draws pipe cutter 5, and draw pipe cutter 5 and be inserted in tubesheet holes 6, holding screw 7 is connected with a stroke pipe cutter 5.
This cutter makes its blade promoting knife bar and draw pipe cutter by constantly rotating eye bolt, produces the pressure of cutting metal required when drawing pipe; Swivel knife carrier is to promote to draw the welded seam area that pipe cutter cuts deep hole end again, realizes the function of manually cutting, removing deep hole pore weld seam.The knife bar with guide function and stroke pipe cutter of cutter ends realize the guiding centering to pipe end, to ensure the cutting precision drawing pipe cutter.Bearing is used, loss of friction during to reduce rotation between stud top with holes and knife bar between the middle part of knife bar and eye bolt top.The top of knife bar is with holding screw internal thread fixing hole.It coordinates with holding screw and is fixed on drawing in pipe Cutting tool installation manner groove of knife bar end by drawing pipe cutter.By changing the cutter of different size or changing the fixing degree of depth of cutter, the overhang of adjustable stroke of pipe cutter.To adapt to different stroke pipe diameters.Knife bar end cut becomes noncircular cross section to pass in and out from plug pore from drawing pipe cutter to facilitate.
When needs carry out drawing pipe to deep hole pipe end, first the plug on the plug tube sheet of former damaged heat exchanger tube position and pad is taken off, insert in the Cutting tool installation manner hole of knife bar end by drawing pipe cutter, again holding screw is rotated in the screwed hole of feed rod end and tighten, being fixed on knife bar end drawing pipe cutter, being adjusted to correct position.Then bearing is installed to knife bar afterbody, then by eye bolt through knife bar, by eye bolt Rotary electrode wire feeding closure plate hole, knife bar is pushed by rotating eye bolt the deep hole pipe end not drawing pipe.Then start to draw pipe work.
When needing to change damaged heat exchanger tube, use this specific purpose tool that the excision of pipe end weld seam conveniently can be taken out damaged heat exchanger tube.
Use the instruments such as spanner to rotate eye bolt, under coordinate of bolt with plug plate hole internal thread, promote knife bar produce stroke pipe blade to the advance pressure of pipe end, then rotate handle of a knife and make a stroke pipe blade start to cut pipe end.When cutting certain depth, the advance pressure drop of knife bar, needs again to rotate eye bolt and continues to keep higher advance pressure.Then, continue to rotate handle of a knife cutting tube end.Until be cut to the suitable stroke pipe degree of depth.
Material as pipe end is comparatively hard, and repeatedly need cut pipe end, adjustable draws pipe cutter.That can install different edge length respectively draws pipe cutter, allows and draws pipe diameter from small to large or from big to small diameter pipe end being cut to needs gradually.
Until when the degree of depth of cutting and diameter meet the demands, exit manual deep hole and draw pipe cutter, complete the cutwork to pipe end.
The end cut of knife bar becomes eccentric shape, and be the internal diameter being generally greater than plug pore owing to drawing the maximum gauge of pipe end, the conveniently turnover of knife bar, becomes thinner eccentric shape by knife bar end cut.
The reach of eye bolt is slightly larger than plug tube plate thickness, determines the cutting depth of stroke pipe to facilitate and adapts to different plug thicknesss of slab.
Knife bar afterbody is slightly long, the centering location before convenient stroke pipe, and adapts to the bobbin carriage of different size.
Knife bar afterbody is processed into several plane, with instrument swivel knife carriers such as spanners easy to use.
The installing hole drawing pipe cutter manufactures rectangular opening, facilitates holding screw to drawing the fixing of pipe cutter.
The advantage of this cutter be simple and reliable for structure, with low cost, draw the features such as pipe speed is fast.Be suitable for using when overhaul of the equipments field condition is not enough.
