After the punching is finished, the two clamping blocks 31 are controlled to slide to be separated from the section bar 100 (as shown in fig. 18 and 19), and the section bar 100 can still be limited from displacing in the positioning groove 221 under the action of the pressing piece 23; then the positioning plate 22 is controlled to rotate to a vertical state, and the length of the section bar 100 is greater than that of the positioning plate 22, so that the end part of the section bar 100 is exposed, and the end part of the section bar 100 can be milled by the milling mechanism 4; in the milling process, as the positioning plate 22 rotates to the vertical state, the milling mechanism 4 can be arranged above (as shown in fig. 2) or below the positioning plate 22, so as to avoid the interference of the clamping block 31 on the milling process. After milling is finished, the positioning plate 22 is controlled to rotate to the horizontal state again, the two clamping blocks 31 are controlled to clamp the left end and the right end of the profile 100 again, and after the profile 100 is clamped again by the two clamping blocks 31, the pressing action of the pressing piece 23 on the profile 100 is released; at this time, as shown in fig. 20, the mounting frame 21 is controlled to slide downwards until the profile 100 is separated from the positioning groove 221, and then the two clamping blocks 31 are controlled to slide backwards so as to convey the profile 100 to the bending mechanism 5 for bending. It should be noted that, the positioning plate 22 and the clamping block 31 corresponding to the hole 101 may be provided with an abdicating hole 223 (as shown in fig. 6) to avoid damage to the punching mechanism and discharge waste generated by punching in time.

Referring to fig. 3, 4, 5, 8 and 9, in some embodiments of the present application, the bending mechanism 5 comprises a female die 51 and two rolling members 52; the die 51 is of an arc structure (the radian of the die 51 is the same as that of the sunroof rail), the die 51 is arranged on the mounting frame 21, and the die 51 is positioned at the rear upper part of the positioning plate 22 in a horizontal state. The two rolling pieces 52 are arranged on the mounting frame 21 in a bilateral symmetry manner, and each rolling piece 52 comprises a rolling wheel 521, a first telescopic rod 522 and a second telescopic rod 523; the rolling wheel 521 is rotatably arranged at one end of the first telescopic rod 522, and the other end of the first telescopic rod 522 is hinged to the mounting frame 21; one end of the second telescopic rod 523 is hinged to the mounting frame 21, and the other end of the second telescopic rod 523 is hinged to the outer side wall of the first telescopic rod 522. During bending, the two second telescopic rods 523 are controlled to extend to enable the two rolling wheels 521 to approach each other, and the two first telescopic rods 522 are controlled to shorten to enable the two rolling wheels 521 to be separated from the female die 51 (as shown in fig. 20 and 21); controlling the two clamping blocks 31 to convey the section bar 100 to the position right below the female die 51, controlling the mounting frame 21 to continuously slide downwards until the middle of the female die 51 is contacted with the middle of the section bar 100, and controlling the two first telescopic rods 522 to extend to enable the two rolling wheels 521 to press the middle of the section bar 100 in the female die 51 so as to limit the section bar 100 between the two rolling wheels 521 and the female die 51; finally, the two clamping blocks 31 are controlled to slide to be separated from the section bar 100, so as to avoid the interference of the clamping blocks 31 on the bending operation, and the two first expansion rods 522 and the two second expansion rods 523 are controlled to extend, so that the two rolling wheels 521 roll from the middle part of the section bar 100 to the left end and the right end of the section bar 100 respectively, so as to force the section bar 100 to fully contact with the female die 51 until the section bar 100 is bent. The process is simple and convenient to control, and under the shaping effect of the female die 51, the size precision of bending is improved. It should be noted that the shapes of the die 51 and the rolling wheel 521 need to be adapted to the shape of the profile 100; in addition, the rotatable installation manner of the rolling wheel 521, the first expansion link 522 itself and the second expansion link 523 itself are all the prior art, and detailed description thereof is omitted.

In addition, because the female die 51 and the positioning plate 22 are both arranged on the mounting frame 21, when the mounting frame 21 is controlled to slide up and down, the female die 51 and the positioning plate 22 can be driven to slide up and down simultaneously, so that the control difficulty can be reduced, and the female die 51 can be always kept above the rear part of the positioning plate 22 in a horizontal state; when the section bar 100 is put in, the positioning plate 22 is positioned at the front side of the female die 51, and the height of the positioning plate 22 is equal to that of the two clamping blocks 31, so that the section bar 100 can be more conveniently placed in the positioning groove 221; during bending, the female die 51 slides downwards along with the mounting frame 21 to a height equivalent to the clamping block 31, and the positioning plate 22 slides downwards along with the mounting frame 21 to a position below the clamping block 31, so that interference of the positioning plate 22 on taking out the section bar 100 can be avoided, and the position of the bent section bar 100 is compared with the position of the section bar 100 when the section bar 100 is put in, the height of the middle part of the section bar 100 is basically unchanged, and only a distance (namely the horizontal distance between the positioning plate 22 and the female die 51 in the front-back direction) is shifted backwards, so that the installation height of the clamping block 31 can be controlled, and a worker can not bend when putting in or taking out the section bar 100.

Referring to fig. 9 and 10, in some embodiments of the present application, a limiting groove 5211 of an annular structure is coaxially disposed on the rolling wheel 521, and a limiting sliding block 511 is coaxially disposed at the lower end of the female die 51; when the rolling wheel 521 presses the profile 100 inside the female die 51, the limiting slide block 511 is in rolling connection with the limiting groove 5211. Under the sliding fit action between the limiting slide block 511 and the limiting groove 5211, the motion of the rolling wheel 521 can be guided and limited, so that the accuracy of rolling (bending) operation can be improved on one hand, and the rolling wheel 521 can be prevented from flattening the profile 100 on the other hand.

When the positioning plate 22 rotates to the horizontal state, the rotary clamping cylinder 231 is controlled to drive the pressing block 233 to rotate to the position right above the positioning groove 221, and then the rotary clamping cylinder 231 is controlled to shorten, so that the lower end of the pressing block 233 can press the profile 100 in the positioning groove 221. When the locking of the profile 100 needs to be released, the rotary clamping cylinder 231 is controlled to extend firstly, so that the pressing block 233 is separated from the profile 100, and then the rotary clamping cylinder 231 is controlled to rotate, so that the pressing block 233 moves to the outer side of the positioning groove 221, and the connecting rod 232 and the pressing block 233 are prevented from interfering other processes. It should be noted that, in order to avoid interference with the control pipeline of the rotating clamping cylinder 231, it is necessary to avoid the positioning plate 22 from rotating too much in the same direction, but various states of the positioning plate 22 can be realized by controlling the positioning plate 22 to rotate forward and backward, for example, during milling, the positioning plate 22 is controlled to rotate clockwise by 90 ° so as to rotate the left end of the profile 100 clockwise to the upper end position, so as to perform milling on the left end of the profile 100, and then the positioning plate 22 is controlled to rotate counterclockwise by 180 ° so as to rotate the right end of the profile 100 counterclockwise to the upper end position, so as to perform the right end of the profile 100.

Referring to fig. 6 and 7, in some embodiments of the present application, at least two pressing members 23 are provided, and a positioning block 234 is provided at a lower end of at least one pressing block 233. Before punching, because the section bar 100 does not have the hole position 101, at this time, the rotary clamping cylinder 231 corresponding to the positioning block 234 is controlled to drive the positioning block 234 to move to the outer side of the positioning groove 221, so as to avoid interference on the punching operation. After punching, due to the fact that the hole position 101 is formed in the section bar 100, the rotary clamping cylinder 231 corresponding to the positioning block 234 is controlled to drive the positioning block 234 to move into the hole position 101 in the section bar 100, the pressing block 233 can compress the section bar 100, and meanwhile, the positioning block 234 and the hole position 101 form positioning fit, so that the locking effect between the section bar 100 and the positioning groove 221 is enhanced, the section bar 100 is prevented from displacing in the positioning groove 221 in the milling process, and the milling precision of the section bar 100 is improved. As shown in fig. 7, a fillet structure or a chamfer structure may be disposed between the lower end surface and the outer side surface of the positioning block 234, and the fillet structure or the chamfer structure may play a guiding role when the positioning block 234 is inserted into the hole 101, so that the positioning block 234 can be inserted into the hole 101 more smoothly; the rounded or chamfered configuration may also prevent the locating block 234 from scratching the profile 100.
