[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4This utility model provides a technical solution: a multi-station workpiece bending device, comprising: a housing 1, a bending mechanism and a cutting mechanism; the bending mechanism and the cutting mechanism are both located on the top of the housing 1;
[0026] The bending mechanism includes a back plate 3, two symmetrical arm plates 5 fixed to the outer wall of the back plate 3, and a pull block 6 fixed between the two arm plates 5. The outer wall of the back plate 3 is provided with an arc-shaped tube groove 4 in a circular shape.
[0027] The cutting mechanism includes a mounting base 7, a support plate 8 slidably connected to the top of the mounting base 7, a laser cutting head 10 fixed to the outer wall of the support plate 8, and a stabilizing block 13;
[0028] The outer walls of the pull block 6 and the stabilizing block 13 are provided with aligned tube insertion holes;
[0029] The top of the chassis 1 integrates two workstations: a bending mechanism and a cutting mechanism. This allows for rapid cutting and bending of steel pipes. In the bending mechanism, the arc-shaped pipe groove 4 of the plate 3 corresponds to half of the pipe insertion hole of the pull block 6 and the stabilizing block 13. These can work together to process one type of steel pipe simultaneously. In the cutting mechanism, the laser cutting head 10 is mainly mounted on the support plate 8 of the mounting base 7. The laser cutting head 10 is connected to an external laser generator for operation. The support plate 8 can be moved horizontally on the top of the mounting base 7 to assist the laser cutting head 10 in cutting the steel pipe.
[0030] More preferably, multiple rows of adjusting screw holes 11 are sequentially opened on the top of the chassis 1, and the mounting base 7 is locked with the adjusting screw holes 11 of the chassis 1 by a limit bolt 12;
[0031] The outer wall of the mounting base 7 has a socket for the limit bolt 12 to be inserted. After the limit bolt 12 is removed, it can be moved to the top of the machine housing 1 so that the socket of the mounting base 7 corresponds to the adjustment screw hole 11, thereby adjusting the position of the laser cutting head 10 to meet the needs of cutting more steel pipes.
[0032] More preferably, a servo motor 2 is fixed inside the chassis 1, and one end of the drive shaft of the servo motor 2 is fixed to the bottom of the back plate 3;
[0033] The rotation of the support plate 3 is controlled by the servo motor 2. The servo motor 2 controls the rotation of the support plate 3 to assist in the bending operation of the steel pipe.
[0034] A further preferred embodiment has a servo cylinder 9 fixed to the top of the mounting base 7, and one end of the telescopic shaft of the servo cylinder 9 is fixed to the outer wall of the support plate 8;
[0035] The movement of the support plate 8 and the laser cutting head 10 is assisted by the servo electric cylinder 9 to perform the translational cutting operation of the steel pipe.
[0036] More preferably, the laser cutting head 10 is positioned vertically downwards between the stabilizing block 13 and the pulling block 6;
[0037] The position of the laser cutting head 10 facilitates the removal of the cut and bent steel pipe by personnel, ensuring that the stabilizing block 13 does not interfere with the removal of the steel pipe.
[0038] One specific application of this embodiment is as follows: This equipment can be used with a servo pipe feeder for steel pipes. The pipe feeder inserts one end of a long steel pipe through the pipe insertion hole of the stabilizing block 13, along the arc-shaped pipe groove 4 of the backing plate 3, and then through the pull block 6. The servo motor 2 controls the backing plate 3 to rotate. As the backing plate 3 rotates, the two arm plates 5 simultaneously drive the pull block 6 to rotate around the backing plate 3. With the delivery of the pipe feeder, one end of the steel pipe is bent after passing through the backing plate 3. After bending to the required degree, the servo electric cylinder 9 controls the support plate 8 to move back and forth, causing the laser cutting head 10 to move horizontally toward the steel pipe to emit a laser for cutting, thus completing the rapid segmentation and bending of the steel pipe. After the segmented and bent steel pipe is removed, the backing plate 3 and the pull block 6 are reset. At this time, the pipe feeder can continue to push the uncut and unbent steel pipe for further processing.
