Needle-tube removes pin machine automatically
Technical field
The present invention relates to a kind of bending tool, more particularly to a kind of needle-tube for needle-tube cylindrical needle bending is removed automatically
Pin machine.
Background technology
The needle-tube set of heat exchange tubes manufactured using needle-tube, with higher heat transfer efficiency, is particularly adapted to compact conformation
Waste heat boiler, in fuel-oil or fuel-gas boiler and oil heater, a series of cylindrical needles are welded on by heat exchanger tube table by automatic welder
Face, from from the same section of needle-tube, many cylindrical needle deciles are arranged in the excircle of needle-tube;From in the axial direction of needle-tube
See, be disposed with multiple rows of by uniform distances in needle-tube periphery, wherein, the length of cylindrical needle, diameter, spacing and inclination angle can bases
Needs are flexibly arranged.With good heat-transfer, small volume, lightweight advantage, preferably from deashing and anti-wear performance, especially
Which is to have more its irreplaceable advantage for the heat exchange of oil based media.
In the production and use of needle-tube set of heat exchange tubes, in order that structure arrangement more compact or arrange more is changed
Heat pipe is needed between longitudinal heat exchanger tube and adjacent cylindrical needle bending is horizontal, referring to figure with meeting the requirement of heat exchange area
In 11 prior arts, the structural representation of needle-tube, Figure 12 are the structural representations in Figure 11 after cylindrical needle bending.At present to pin
The bending of the cylindrical needle of shape pipe, can only adopt manual type, because the cylindrical needle arrangement on same needle-tube axial direction is closeer, be
Guarantee yield rate and avoid damage to, significantly increase the labor intensity of workman, efficiency is low, waste time and energy, increased cost.
Chinese patent (application number:201210557926.1, authorized announcement date:2015.01.21) disclose a kind of pneumatic slotting
