Description

Preferably, the motor 321 is a servo motor.

[0054] like Figure 2 As shown, the extension rod 322 includes a sleeve 3221 fixed to the motor 321, an inner rod 3222 is inserted into the sleeve 3221, a connecting rod 3223 is fixed to one end of the inner rod 3222, an end of the connecting rod 3223 away from the inner rod 3222 is fixed to one end of one of the universal transmission units 323, and a fixing bolt for resisting the inner rod 3222 is threadedly penetrated on the sleeve 3221;

[0055] Specifically, after loosening the fixing bolt, the inner rod 3222 can be pulled out to one side, so that the initial position of the inner support unit 33 changes. After adjusting its initial position to a suitable position, the fixing bolt is re-tightened, and the end thereof extending into the sleeve 3221 abuts against the surface of the inner rod 3222, so that the inner rod 3222 abuts against the sleeve 3221, thereby fixing the initial position of the inner support unit 33.

[0056] like Figure 2 , Fig.10 , Fig.11 and Fig.13 As shown, the inner support unit 33 includes a plurality of slide seats 331, each of which is sleeved with a slide sleeve 332, a middle arc-shaped support block 333 is fixed on the slide sleeve 332, both ends of the middle arc-shaped support block 333 are rotatably connected with side arc-shaped support blocks 334, and a deformation support assembly 335 is assembled on the side arc-shaped support block 334, a plurality of threaded holes are opened in the middle of one side of the slide seat 331, a fixing bolt matching the threaded hole is threadedly connected to the bottom of one side of the slide sleeve 332 through a countersunk hole, and a plurality of second limiting sliding grooves 337 are opened on the inner side of the mounting plate 341;

[0058] Specifically, when the round tube is bent, the inner support unit 33 is in the initial state, that is, the first state (eg Fig.10 ), at this time, several groups of middle arc-shaped support blocks 333 and side arc-shaped support blocks 334 are combined into an unclosed circular shape;

[0059] When bending a square tube with a square cross-section, after loosening the positioning bolts, slide the telescopic rod 3351 upward to rotate the side arc support block 334 upward. After the side arc support block 334 can no longer rotate, stop sliding the telescopic rod 3351, and then tighten the positioning bolts to fix the position of the telescopic rod 3351, thereby fixing the position of the side arc support block 334. At this time, the apex of the rotated side arc support block 334 and the apex of the middle arc support block 333 are in the same straight line, and the overall contact position is in a "W" shape when contacting the inner wall of the square tube. At this time, the inner support unit 33 is adjusted to the second form (such as Fig.11 );

[0060] When bending a square tube with a rectangular cross section, after adjusting to the second state, loosen the fixing bolts on the upper and lower sliding sleeves 332, and then move the sliding sleeves 332 according to the length-width ratio of the square tube, so that the side arc support blocks 334 and the middle arc support blocks 333 on the upper and lower sliding sleeves 332 are moved to a suitable position, so that the ratio of the rectangle surrounded by the adjusted groups of side arc support blocks 334 and the middle arc support blocks 333 is the same as that of the square tube. At this time, the inner support unit 33 is adjusted to the third state (such as Fig.13 ).

[0061] like Figure 6 and Figure 7 As shown, the adjustment assembly 34 includes a mounting plate 341, a shaft column 342 is fixed at one end of the horizontal connection seat 3233, the shaft column 342 is rotatably connected to the mounting plate 341, an adjustment plate 343 is fixed at one end of the shaft column 342 that passes through the mounting plate 341, one end of the vertical connection seat 3231 is fixed to the outer wall of the adjustment plate 343, and a plurality of guide grooves 344 distributed in a circumferential array are opened on the adjustment plate 343;

[0062] A plurality of first limiting slide grooves 345 distributed in a circumferential array are provided at the inner edge of the adjusting disk 343, a plurality of first limiting sliders 346 adapted to the first limiting slide grooves 345 are fixed at the inner edge of the mounting disk 341, and the mounting disk 341 is connected to the adjusting disk 343 via the first limiting sliders 346;

[0063] A guide rod 336 adapted to the guide groove 344 is fixed to the bottom of one side of the slide 331, and the guide rod 336 is inserted into the guide groove 344. A second limiting slider 338 adapted to the second limiting slide groove 337 is fixed to the other side of the slide 331 and the slide sleeve 332. The slide 331 and the slide sleeve 332 are slidably assembled on the mounting plate 341 through the second limiting slider 338.

[0064] After the inner support unit 33 is moved to the position where the stainless steel pipe is to be bent by the electric push rod 31, the motor 321 is started to drive the extension rod 322 to rotate, and the multiple adjustment disks 343 are rotated together under the action of the universal transmission unit 323. During the rotation process, the middle arc support block 333 and the side arc support blocks 334 are driven to gradually move outward under the action of the guide groove 344, gradually abutting against the inner wall of the steel pipe to support the inner wall of the steel pipe.

[0065] like Figure 4 and Figure 6 As shown, the universal transmission unit 323 includes a vertical connection seat 3231, one end of the connection rod 3223 away from the inner rod 3222 is fixed to the vertical connection seat 3231, a cross connection member 3232 is rotatably connected in the vertical connection seat 3231, and the other two ends of the cross connection member 3232 are rotatably connected to the transverse connection seat 3233;

[0066] The middle parts of the four ends of the cross connecting member 3232 are provided with mounting holes, and springs 3234 are fixed in the mounting holes. A hemispherical block 3235 for limiting the position of the vertical connecting seat 3231 and the horizontal connecting seat 3233 when moving is fixed at one end of the spring 3234. The vertical connecting seat 3231 and the horizontal connecting seat 3233 are provided with through slots 3236 adapted to the hemispherical block 3235.

[0067] In the initial state, the hemispherical block 3235 is clamped in the through slot 3236 under the action of the spring 3234, so that the cross connecting piece 3232 and the vertical connecting seat 3231 and the horizontal connecting seat 3233 are in a clamped and fixed state, so that when the electric push rod 31 pushes the inner support unit 33 toward the bending position of the steel pipe, it can remain horizontal and the inner support unit 33 will not swing.

[0068] Specifically, when the stainless steel pipe multi-dimensional bending equipment is working / in use:

[0069] First, the stainless steel pipe to be bent is inserted into the inner support unit 33, and then one end of the stainless steel pipe is fixed by the clamping mechanism 70, and then the moving mechanism 40 pushes the part of the stainless steel pipe to be bent to the bending mechanism 20, and then the electric push rod 31 is started to push the inner support unit 33 to the position where the stainless steel pipe is to be bent, and then the motor 321 is started to drive the extension rod 322 to rotate, and under the action of the universal transmission unit 323, the multiple adjustment disks 343 are rotated together, and the sliding seat 331 is driven to slide outward gradually under the action of the guide groove 344 during the rotation process, and at the same time, the middle arc support block 333 and the side arc support block 334 are gradually moved outward, and finally, the outer wall of the middle arc support block 333 and the side arc support block 334 are abutted against the inner wall of the stainless steel pipe to support the inner wall of the stainless steel pipe;

[0070] At this time, the stainless steel pipe is bent by the bending mechanism 20. During the bending process, the inner support unit 33 supports the inner wall of the steel pipe. At the same time, under the action of the universal transmission unit 323, the inner support unit 33 can rotate along with the bending of the steel pipe. After the bending of this part is completed, the motor 321 is started again to make the adjustment disk 343 rotate in the opposite direction, so that the middle arc support block 333 and the side arc support block 334 are away from the inner wall of the stainless steel pipe. At this time, the inner support unit 33 is pulled back by the electric push rod 31 to move it out of the bending part. After the movement, the arc support block is driven to contact the inner wall of the steel pipe by the motor 321, and then the inner support unit 33 is continuously pulled by the electric push rod 31. During the movement, the angle of the inner support unit 33 is reset under the action of the inner wall of the steel pipe.

[0071] After resetting, when the stainless steel tube needs to be bent in different dimensions, the stainless steel tube is rotated to the required angle through the rotating mechanism 50, and then the above operation of pushing the inner support unit 33 to move to the position to be bent is repeated, and the bending operation is performed. After the operation is completed, the fixation of the stainless steel tube is released, and then the stainless steel tube can be pulled out from the inner support unit 33.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
