As shown in fig. 1 and 6, in order to improve the cutting accuracy, in the present embodiment, the follow-up cutting device 2 includes a length measuring device for measuring the length of the profile, the length measuring device includes a length measuring wheel 27 having an outer peripheral surface for contacting the profile, and a rotary encoder 28 connected to the length measuring wheel 27, and the rotary encoder 28 is used for counting the number of rotations of the length measuring wheel 27. The distance of movement of the profile can be obtained by calculating the number of turns of the length measuring wheel 27 and the circumference of the length measuring wheel 27. The follow-up cutting device 2 further comprises a cutting position detection sensor 29 for detecting the cutting position on the profile against the position of the process hole. The cut-off position detection sensor 29 may be provided upstream of the plug or downstream of the plug.

Therefore, the influence of the forming process on the length measuring device can be reduced, the influence of profile jumping on the measuring device in the cutting process of the cutter can be reduced, and the measuring data of the length measuring device are more accurate. In other embodiments, the length measuring device may be disposed upstream of the shaping process.
The working principle of the medium-sized material continuous production line in this embodiment is as follows:
the raw material of the profile 4 is in a long strip shape, is conveyed to a production line through a conveying device, is punched into a cutting position contrast process hole through a punching device, is processed and molded through a roll forming device 1, and moves forwards under the action of the roll forming device 1.
The section bar 4 passes through the workpiece groove of the fixed knife until the cutting position is detected by the cutting position detection sensor 29 and is compared with the process hole, the length measuring device starts to measure the advancing distance of the section bar 4, after the position to be cut of the section bar 4 reaches the cutting position of the cutter on the movable knife rest, the controller controls the plug 24 to move upwards to a follow-up state, the plug 24 is inserted into a process jack, the section bar 4 continuously moves, the movable knife rest 22 is driven to synchronously move by the plug 24, at the moment, the cutter driving mechanism 23 on the movable knife rest 22 drives the movable knife to move downwards to cut off the section bar 4, and the cut part falls and stacks after the section bar 4 is cut off. The cutter driving mechanism 23 drives the movable cutter to move upwards, the bolt 24 moves downwards to a disengaged state under the action of the transmission member driving mechanism 25, and the movable cutter frame 22 stops moving forwards. During the forward movement of the moving blade carrier 22, the piston rod of the blade carrier driving cylinder 26 is in a free state and continuously retracted, and after the profile 4 is cut off, the moving blade carrier 22 stops moving forward, and at this time, the blade carrier driving cylinder 26 is started to drive the moving blade carrier 22 to move backward to the initial position. The whole cutting process is automatically controlled by the controller. The above process is repeated, and continuous cutting of the section bar 4 can be realized without stopping.
In this embodiment, in order to ensure the running stability, the roll forming device 1 resumes the high speed after the profile is cut off at the movement speed when the pin is inserted into the process jack to drive the moving tool rest 22 to move forward and the movement speed when the pin is separated from the process jack, which is beneficial to improving the production efficiency. Of course, in other embodiments, when the control accuracy of each part mechanism is high, the running speed of the roll forming apparatus may be kept high continuously.
Embodiment 2 of the continuous profile production line according to the present invention, the continuous profile production line in this embodiment differs from the above embodiment only in that: in this embodiment, the cutter driving mechanism is a linear motor. In other embodiments, the linear motion drive mechanism of the present invention is provided. For example, the driving mechanism of the transmission part, the driving mechanism of the driving tool rest and the like can be linear motors, driving oil cylinders, driving air cylinders, screw and nut mechanisms driven by motors, gear and rack mechanisms driven by motors, crank sliding block connecting rod mechanisms and the like.
Embodiment 3 of the continuous profile production line according to the present invention, the continuous profile production line in this embodiment differs from the above embodiment only in that: the follow-up cutting device does not need to adopt a length measuring device, and the length of the profile is controlled through the running time, for example, when the length to be cut off is longer, the control controller controls the bolt to extend for a period of time. The process jacks on the profile also need to be correspondingly changed. In order to facilitate flexible adjustment, the profile transmission part adopts an electromagnet to suck out the profile or adopts a clamping jaw to clamp the profile conveniently. In other embodiments, the length measuring device may also employ laser detection. In other embodiments, when the control of the running time is accurate, the length measuring device is not required to be arranged, and only the position of the section to be cut on the section is required to be ensured to correspond to the cutting position of the cutter.
Embodiment 4 of the continuous profile production line according to the present invention, the continuous profile production line in this embodiment differs from the above embodiment only in that: the length measuring device is arranged at the downstream of the roll forming device.
Embodiment 5 of the continuous profile production line according to the present invention, the continuous profile production line in this embodiment differs from the above embodiment only in that: because the knife rest driving mechanism only needs to drive the movable knife rest to reset, the piston rod of the driving cylinder of the movable knife rest in the embodiment drives the movable knife rest to move in a pushing mode and is not connected with the movable knife rest.
The above description is only a preferred embodiment of the present invention, and the patent protection scope of the present invention is defined by the claims, and all equivalent structural changes made by the specification and the drawings of the present invention should be included in the protection scope of the present invention.
