Description

The bending machine angle adjusting device that verts

The utility model relates to a kind of bending machine, particularly relates to a kind ofly being easy to set and the simply constructed bending machine angle adjusting device that verts.

As shown in Figure 1, generally be many bendings pipe workpiece 9 (as blast pipe), for reaching continuously and the construction of the different tilt angles of tool, mainly be to utilize a kind of bending machine and the purpose that reaches bend pipe processing, the essential structure of bending machine is to be provided with a slide rail at a board end face along length direction, be equiped with a spindle drum that can in good time slide on this slide rail, an end that is symmetrical in this slide rail is provided with a tailstock, the other end then is provided with a swan neck system, and a stock that utilizes a universal joint to articulate on this tailstock can be stretched this swan neck system one side is set, and stretch and be located at workpiece inside, when the set chuck of main shaft one end of this spindle drum with piece-holder, the workpiece other end then can be subjected to the clamping of swan neck system and bending (during bending this spindle drum be subjected to workpiece bending length shorten and produced displacement by towing along slide rail), bending Hou, this swan neck system discharges workpiece, and this workpiece does feeding and rotate suitable tilt angle Hou, just can carry out the circulation of next bend pipe action again.

General bending machine divides with performance, the NC bending machine is arranged, the CNC bending machine, three kinds of semi-automatic bending machines etc., wherein the manufacturing cost of NC bending machine is lower, but it is digital control that the bending action that has only swan neck system is subjected to, workpiece feeding and workpiece tilt angle all must be earlier with artificial adjustment before operation each time, so the operation on comparatively the trouble and production capacity lower, and the workpiece feeding length of CNC bending machine, tilt angle and bending angle all utilize computer numeral control to cooperate servomotor or pressure cylinder to control, so cost is comparatively expensive, semi-automatic bending machine then is a kind of relaying machine between NC bending machine and CNC bending machine, it is in advance by the feeding length of manually setting workpiece according to processing sequence, tilt angle and cooperation are by numerically controlled swan neck system, have more the effect that can improve production capacity than NC bending machine, cost is again unlike CNC bending machine costliness.As shown in Figure 2, a kind of structure of semi-automatic bending machine, be to be provided with a slide rail 101 along length direction at a board 1 end face, be equiped with a spindle drum 2 that can in good time slide on this slide rail 101, an end that is symmetrical in this slide rail 101 is provided with a tailstock 3, the other end then is provided with a swan neck system 4, and utilize a universal joint 301 to be articulated with a stock 5 on this tailstock 3, these stock 5 other ends may extend to this swan neck system 4 one sides passing spindle drum 2 inner Hous, cooperate Fig. 3, shown in 4, this spindle drum 2 is to be installed with a framework 202 at a planker 201 end faces, this framework 202 is provided with a main shaft 203 than the lower position axle, this main shaft 203 is to be subjected to the control of a control device 6 and can to reach the location purpose rotating suitable angle Hou, this control device 6 includes locking several locating rings 601 in this main shaft 203 outsides, several cams 602 and several select bar 603, be equipped with a draw-in groove 604 on each locating ring 601, and the draw-in groove 604 of these locating rings 601 is adjusted to the predetermined angle of being separated by according to the needs of processing tilt angle, have eight cams 602 in the drawings, each cam 602 all has an onesize groove 605, and is isogonism (45.) stagger, this is selected bar 603 1 ends and is provided with a fixture block 606, the other end is pivoted with a wheel body 607, and these wheel body 607 inboards are linked on the framework 202 with an extension spring 608, this control device 6 is to utilize a pressure cylinder 701, one pawl 702 and a ratchet 703 drive, this pawl 702 is installed in pressure cylinder 701 front ends, this ratchet 703 then with these cam 602 coaxial setting firmly, by this, when these pressure cylinder 701 every promotion ratchets 703 once, this cam 602 is just by related rotation, just have cam 602 grooves 605 inside that a wheel body 607 of selecting bar 603 is absorbed in symmetry this moment, and this fixture block 606 of selecting bar 603 other ends pushes against locating ring 601 side faces in correspondence, and when this locating ring 601 rotates (just operating personnel's turning of work piece and make workpiece drive this main shaft 203 rotate) with main shaft 203, this fixture block 606 is embedded in the draw-in groove 604, and the machining angle that makes this main shaft 203 vert and be positioned to preset, and, can make these select bar 603 start in regular turn because the isogonism of these cams 602 is arranged, be embedded in each locating ring 601 in regular turn.

Though utilize above-mentioned control device 6 can reach the purpose of control workpiece tilt angle, but, when setting each locating ring 601, mainly be that side face at each locating ring 601 all is provided with scale, and when setting, be that first locating ring 601 is set locking at the zero degree state, and all be under the state that becomes flexible and do not lock at other locating rings 601, make that the draw-in groove 604 of second fixture block 606 of selecting bar 603 and second locating ring 601 is chimeric, rotate this main shaft 203 this moment, first locating ring 601 can rotate with main shaft 203, and the scale by first locating ring 601 and second locating ring 601 side face is poor, just can observe out the tilt angle value of second locating ring 601, be locked when adjusting to the angle value that desire sets again, other locating rings 601 are also to set with method, but, this setting means not only bothers, operation is slow, and can be subject to the precision of rule with the tilt angle value that visual scale difference is set workpiece, and is also comparatively not accurate.

The purpose of this utility model is to provide a kind of bending machine angle adjusting device that verts, and be to utilize the adjusting device just can be easily and set the tilt angle of workpiece exactly, and setting operation speed is fast.

The utility model bending machine angle adjusting device that verts, be to be provided with a slide rail along length direction at a board end face, this slide rail is provided with a slidably spindle drum, one end of this slide rail of symmetry is provided with a tailstock, the other end is provided with a swan neck system, and articulate a stock with a universal joint on this tailstock, this stock other end may extend to swan neck system one side, this spindle drum is installed in a planker end face with a framework, this place, framework below axle is provided with a main shaft, this main shaft is subjected to the control of a control device and rotates and locate, this control device comprises locking several angle orientation rings in this main shaft outside, several cams and several select bar, all be provided with a draw-in groove on each locating ring, this is selected bar one end and is provided with one and pushes against at the locating ring side face of correspondence and can embed fixture block in this draw-in groove, the other end is pivoted with the wheel body in the groove that can be absorbed on the symmetrical cam, wherein, this adjusting device comprises an active member that is installed on this main shaft and rotates synchronously with main shaft, produce the drive element that multiple rotates during one driving, one produces the decoder of pulse value when drive element rotates, but the programmed logic controller of this pulse value of computing and shows the display of this main shaft rotational angle.
