U-shaped pipe swan neck system
The utility model belongs to machining equipment field, specifically a kind of U-shaped pipe swan neck system for U-shaped tube bank in U-shaped heat exchange of heat pipe.
In prior art, many employings that bends of U-shaped tube bank manually bend, and labor intensive cost is large, the speed that bends is slow and bend weak effect, bend radius compared with easily to cause bend loss degree of folding time little large, out-of-roundness exceeds standard, even cause pipe to flatten.
Utility model content
For the defect of prior art, the object of this invention is to provide the U-shaped pipe swan neck system that a kind of structure is simple, easy to operate, bend pipe efficiency is high and effective.
The technical solution of the utility model is: comprise drive unit, moment of torsion output panel, workbench, disk bending die, central shaft, bearing pin, planetary gear, turning rolls and steady pin; The output of described drive unit connects moment of torsion output panel; The center fixed center axis of described workbench, and table top to be provided with central shaft be the annular cotter way in the center of circle; Fixed disc bending die on described central shaft; One end of described turning rolls is filled on center shaft by shaft hole sleeve and can rotate around central shaft, and turning rolls is provided with continuously arranged multiple locating hole, described planetary gear is arranged in locating hole by bearing pin, and planetary gear formation body corresponding with disk bending die clamp structure; Lock in the pin-and-hole that described steady pin is through described annular cotter way and lower end is fixed on moment of torsion output panel, upper end is inserted on turning rolls; Described workbench is also provided with body fixed mechanism.
Such scheme is more preferably:
Described turning rolls comprises upper and lower two-arm and upper and lower two-arm is arranged in the upper and lower both sides of disk bending die, and upper and lower two-arm is provided with corresponding continuously arranged multiple locating hole; Described planetary gear is arranged between upper and lower two-arm by bearing pin and locating hole.
Described body fixed mechanism is olecranon iron spanner.
Described drive unit is angle-bender
Compared with prior art, the utility model has the following advantages: 1, turning rolls is designed to loose structure, by adjusting the position of bearing pin and planetary gear, has both achieved the continuous adjustment of elbow radius, solves again the problem that planetary gear clamping does not tightly cause slip; 2, adopt electric steel bar bender to provide moment of torsion to replace the type of drive of artificial pushing rolling wheels frame, ensureing the uniformity that bend pipe process moment of torsion provides and successionally saving cost of labor simultaneously.

Detailed description of the invention
See Fig. 1, a kind of U-shaped pipe swan neck system, comprising drive unit 8(can be chosen as angle-bender), moment of torsion output panel 1, workbench 2, disk bending die 3(periphery be with the semicircle coincide with body or arc tube seat), central shaft 4, bearing pin 5, planetary gear 6, turning rolls 7, steady pin 9 and body fixed mechanism 10; The output of drive unit 8 connects moment of torsion output panel 1; The center fixed center axis 4 of workbench 2, and table top to be provided with central shaft be the annular cotter way in the center of circle; Fixed disc bending die 3 on central shaft 4; Turning rolls 7 is comprised upper and lower two-arm and to be all contained in by the shaft hole sleeve of one end on the central shaft of disk bending die 3 both sides and can to rotate around central shaft, and upper and lower two-arm is provided with corresponding continuously arranged multiple locating hole; Planetary gear 6 is arranged between upper and lower two-arm by bearing pin 5 and locating hole, planetary gear 6 formation body corresponding with disk bending die 3 clamp structure; Lock in the pin-and-hole that steady pin 9 is through annular cotter way and lower end is fixed on moment of torsion output panel 1, upper end is inserted on turning rolls 7 underarm; Workbench 2 is also provided with body fixed mechanism (such as olecranon iron spanner).
1, central shaft is welded on workbench center through the axis hole (constrained port) of turning rolls one end, disk bending die centre bore, forms the center that turning rolls rotates around disk bending die;
2, planetary gear is fixed in the locating hole of turning rolls by bearing pin, clamps pipe in order to coordinate with disk bending die;
3, steady pin is connected on driving-disc (i.e. moment of torsion output panel) through the annular pin slot welding on workbench, and the pin-and-hole inserting turning rolls underarm provides driving force to drive turning rolls to rotate.
Choose the bending die of respective diameters according to required U-shaped pipe diameter during work, adjustment planetary gear position, pipe is inserted in the middle of bending die and planetary gear, make planetary gear just to inflection point, pull body fixed mechanism clamping pipe, starting drive unit drives turning rolls to rotate around disk bending die by moment of torsion output panel, straight tube is completed the U-shaped pipe of pattern requirement.
By the utility model, the beneficial effect obtained is: 1, work class system adjusts to 3 people/class by 4 people/class, saves labor cost 25%; 2, operating efficiency brings up to bend pipe 500 every day from bend pipe 250 every day in past, increases work efficiency 100%; 3, workpiece quality brings up to 100% from original qualification rate less than 80%, saves a large amount of former material cost.
In the middle of this covering device puts into production, after adopting this device by the information of actual feedback, work is very smooth, reach Expected Results, ensure for a large amount of subsequent products provides technology, remarkable in economical benefits improves.
Below be only exemplary embodiments of the present utility model, those skilled in the art can do suitable modification and improvement completely on its basis, but identical with the utility model substance, fall into protection domain of the present utility model equally.
