Detailed implementation manners

[0032] The following describes the preferred implementation manners of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0033] The present utility model provides a size calibration device for cold-formed channel steel, including:

[0034] Workbench 1, used for carrying the channel steel;

[0035] N-shaped frame 2, arranged on the upper end surface of the workbench 1;

[0036] The n-shaped frame 2 is fixedly installed on the upper end surface of the workbench 1 and can be relatively fixed;

[0037] Sliding blocks 3, in a pair, both sliding on the upper end surface of the workbench 1 and located below the n-shaped frame 2;

[0038] Through hole 4, formed in the sliding block 3;

[0039] Sliding pin 5, arranged in the through hole 4 and extending out of both ends of the through hole 4 at both ends;

[0040] Tension spring 16, wound and installed on the outer surface of the sliding pin 5, and one end is fixedly connected to the outer surface of the sliding pin 5, and the other end is fixedly connected to the inner surface of the through hole 4;

[0041] The sliding of the sliding block 3 can drive the sliding pin 5 to move, so that one end of the sliding pin 5 contacts the outer wall surface of the channel steel;

[0042] Infrared emitters 6, in a pair, respectively arranged on the end faces of a pair of sliding blocks 3 away from each other;

[0043] The infrared emitter 6 is fixedly connected to the outer wall surface of the sliding block 3 and can be relatively fixed;

[0044] The infrared receivers 7, with a pair in number, are respectively arranged on the end faces of a pair of sliding blocks 3 away from each other, and are used to respectively receive the infrared rays emitted by a pair of infrared emitters 6;

[0045] The infrared receivers 7 are fixedly connected to the outer wall surface of the sliding block 3 and can be relatively fixed;

[0046] The controller 8 is fixedly installed on the upper end face of the n-shaped frame 2 and is electrically connected to a pair of infrared emitters 6 and a pair of infrared receivers 7 respectively;

[0047] The alarm 9 is fixedly installed on the upper end face of the n-shaped frame 2 and is electrically connected to the controller 8;

[0048] When the channel steel is bent, one end of the sliding pin 5 in contact with it can contract into the through hole 4, and the other end of the sliding pin 5 can slide between the infrared emitter 6 and the infrared receiver 7 to block the infrared rays emitted by the infrared emitter 6. At this time, when the infrared receiver 7 cannot receive the infrared rays, it will send the information to the controller 8 in the form of an electrical signal, so that the controller 8 controls the alarm 9 to give an alarm to remind the staff and facilitate the staff to find the bending point of the channel steel;

[0049] The driving mechanism is arranged in the n-shaped frame 2 and is used to drive a pair of sliding blocks 3 to move.

[0050] Specifically, the driving mechanism includes;

[0051] The groove 10 is formed in the lower end face of the upper wall of the n-shaped frame 2;

[0052] The bidirectional threaded rod 11 is rotatably installed in the groove 10;

[0053] One end of the driving block 12 is fixedly connected to the upper end face of the sliding block 3, and the other end is slidably installed in the groove 10 and is threadedly connected to the bidirectional threaded rod 11;

[0054] When the bidirectional threaded rod 11 rotates, it can drive a pair of driving blocks 12 to approach or move away from each other simultaneously, and the distance between them can be adjusted according to the size of the channel steel so that one end of the sliding pin 5 can contact its outer surface. At the same time, the inner wall surface of the groove 10 forms a limiting groove, and a limiting block slidably connected to the limiting groove is fixedly installed on the outer wall surface of the driving block 12, which can make the driving block 12 slide more stably in the groove 10 and improve the measurement accuracy of the sliding pin 5.

[0055] Specifically, a through port 13 is formed in one end of the driving block 12 located outside the groove 10, and a measuring ruler 14 is arranged in the n-shaped frame 2, and the measuring ruler 14 penetrates through the through port 13;

[0056] On the end faces of a pair of sliding blocks 3 that are close to each other, pointers 15 used in cooperation with the measuring scale 14 are fixedly installed respectively;

[0057] The movement of the sliding block 3 can drive the pointer 15, so that one end of the pointer points to the scale on the measuring scale 14, facilitating the staff to adjust the distance between a pair of sliding pins 5 according to the specifications of the channel steel.

[0058] Specifically, on the upper end face of the workbench 1 and on one side of the n-shaped frame 2, a pair of fixed seats 17 are fixedly installed, and a pair of sliding plates 18 are arranged between the pair of fixed seats 17;

[0059] A guide wheel 19 is arranged on one end face of the sliding plate 18, and the outer surface of the guide wheel 19 is in contact with the outer surface of the channel steel;

[0060] A threaded rod 20 is rotatably installed on one end face of the sliding plate 18, and the threaded rod 20 is in threaded connection with the fixed seat 17;

[0061] The rotation of the threaded rod 20 can drive the sliding plate 18 and the guide wheel 19 to move, facilitating the contact between the guide wheel 19 and the channel steel. At the same time, there are multiple guide wheels 19, which can clamp the channel steel to keep its position straight, facilitating the calibration of the size of the channel steel.

[0062] Specifically, a slide bar 21 is fixedly installed on one end face of the sliding plate 18, and the end of the slide bar 21 away from the sliding plate 18 slidably penetrates through the fixed seat 17;

[0063] When the sliding plate 18 slides, it can drive the slide bar 21 to slide in the fixed seat 17, which can limit the sliding position of the sliding plate 18 and prevent it from shaking.

[0064] Working principle: First, the staff place the channel steel on the workbench 1, and at the same time, one end of it is between a pair of sliding blocks 3. At this time, the staff rotate the bidirectional threaded rod 11. The rotation of the bidirectional threaded rod 11 can drive a pair of driving blocks 12 respectively, so that a pair of sliding blocks 3 approach each other. At the same time, the sliding of a pair of sliding blocks 3 can drive a pair of pointers 15 respectively. The measuring scale 14 can measure the distance between a pair of pointers 15, make the distance between them the same as the size of the channel steel, and make one end of the sliding pin 5 contact the outer wall surface of the channel steel. At this time, the staff rotate a pair of threaded rods 20 respectively. The rotation of the threaded rods 20 can drive the sliding plate 18 and the guide wheels 19 to move simultaneously, so that the guide wheels 19 contact the outer wall surface of the channel steel to clamp the channel steel and make the channel steel in a straight state. At this time, the staff operate the controller 8 to start a pair of infrared emitters 6. The pair of infrared emitters 6 emit infrared rays respectively, so that a pair of infrared receivers 7 receive the infrared rays respectively. At this time, the staff push the channel steel. When the channel steel moves, the sliding pin 5 can measure the size of the channel steel. When the channel steel is bent, the sliding pin 5 can slide, so that one end of it blocks the infrared rays emitted by the infrared emitter 6. When the infrared receiver 7 cannot receive the infrared rays, it transmits an electric signal to the controller 8, so that the controller 8 controls the alarm 9 to alarm, reminding the staff and facilitating the staff to straighten the bending point of the channel steel, which brings convenience to people.
