Description

Technical Field

[0001] This utility model relates to the field of roll forming of steel profiles, specifically a roll forming measuring instrument for cold-bent steel profiles. Background Technology

[0002] Cold-formed steel is widely used in construction, machinery manufacturing and other fields due to its advantages such as high efficiency and energy saving and reasonable cross-section. During the feeding, turning and rolling process of cold-formed steel, the dimensional accuracy of the rolls directly affects the connection strength and assembly quality of the profile.

[0003] Traditional roll forming measuring tools are scattered and complex to operate, requiring the use of calipers, angle gauges, and other equipment to measure the bottom edge, side edge, and angle of the roll forming. This is not only time-consuming and labor-intensive, but also increases the workload due to multiple measurements. Especially in the case of a fast-moving production line, frequent tool switching severely restricts the detection efficiency. Therefore, it is necessary to design a cold-bent steel roll forming measuring instrument to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cold-bent steel roll forming measuring instrument to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold-bent steel roll forming measuring instrument, including a measuring ruler, two symmetrically opened sliding grooves on the front side of the measuring ruler, a slider slidably installed inside the sliding groove, a connecting column welded to one side of the slider, and a fixing plate fixedly installed on one side of the connecting column;

[0006] A rotating column is rotatably mounted on one side of the fixed disk, and a movable ruler plate for measuring length is slidably mounted inside the rotating column.

[0007] Preferably, the measuring ruler has length markings on its surface, and the fixed plate has angle markings on its surface.

[0008] Preferably, the surface of the movable ruler is marked with length graduations.

[0009] Preferably, a magnetic strip is embedded on the top surface of the measuring ruler.

[0010] Preferably, both ends of the movable ruler are fixedly installed with blocks, and the cross-sectional area of ​​the blocks is larger than that of the movable ruler.

[0011] Preferably, the slider has a trapezoidal cross-section, and the slider cross-sectional dimensions match the groove cross-sectional dimensions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This cold-bent steel roll forming measuring instrument is used by attaching the measuring ruler to the bottom surface of the roll forming. The length of the bottom edge of the roll forming can be measured through the length scale on the surface of the measuring ruler. Then, by moving the slider, the connecting column, fixed plate, rotating column and movable ruler plate move together. Rotating the movable ruler plate drives the rotating column to rotate, so that the movable ruler plate is parallel to the side of the roll forming and attached to the side surface of the roll forming. At this time, the angle of the side of the roll forming is measured by comparing the movable ruler plate with the angle scale on the surface of the fixed plate. The operation and reading are very convenient and ensure measurement efficiency.

[0014] 2. This cold-bent steel roll forming measuring instrument allows for the measurement of the roll forming side length by sliding the movable ruler plate against the roll forming side and passing through the scale on the movable ruler plate surface. It integrates the measurement of the roll forming bottom edge length, side edge length, and side edge angle. When measuring roll forming of materials such as carbon steel that can be magnetically attracted, the measuring ruler can be operated without holding the instrument, making the angle measurement and reading convenient and quick.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4 As shown, this utility model provides a cold-bent steel roll flower measuring instrument, including a measuring ruler 1. Two sliding grooves 3 are symmetrically opened on the front side of the measuring ruler 1. A slider 4 is slidably installed inside the sliding groove 3. A connecting column 5 is welded to one side of the slider 4. A fixed plate 6 is fixedly installed on one side of the connecting column 5.

[0022] A rotating column 7 is rotatably mounted on one side of the fixed plate 6, and a movable ruler 8 for measuring length is slidably mounted inside the rotating column 7.

[0023] Specifically, the measuring ruler 1 is attached to the bottom surface of the roller flower. The length of the bottom edge of the roller flower can be measured by the length scale on the surface of the measuring ruler 1. Then, by moving the slider 4 and rotating the movable ruler plate 8, the movable ruler plate 8 is attached to the side surface of the roller flower. At this time, the angle of the side of the roller flower is measured by comparing the movable ruler plate 8 with the angle scale on the surface of the fixed plate 6, and the length of the side of the roller flower is measured by the movable ruler plate 8.

[0024] Among them: the measuring ruler 1 has a length scale marked on its surface, the fixed plate 6 has an angle scale marked on its surface, and the movable ruler 8 has a length scale marked on its surface. The length of the bottom edge of the roller can be measured by the length scale on the measuring ruler 1, the side angle of the roller can be measured by comparing the movable ruler 8 with the angle scale on the fixed plate 6, and the side length of the roller can be measured by the scale on the movable ruler 8.

[0025] Among them, the top surface of the measuring ruler 1 is embedded with a magnetic strip 2, which can attract the bottom surface of the roller with magnetic material. When the measuring personnel use it, they can take the measuring ruler 1 out of their hands, making the operation more convenient.

[0026] Among them, both ends of the movable ruler plate 8 are fixedly installed with stop blocks 9. The cross-sectional area of ​​the stop blocks 9 is larger than the cross-sectional area of ​​the movable ruler plate 8. The two stop blocks 9 prevent the movable ruler plate 8 from detaching from the inside of the rotating column 7.

[0027] Wherein: the cross section of slider 4 is trapezoidal, and the cross section size of slider 4 matches the cross section size of slide groove 3. Slider 4 can slide inside slide groove 3 without leaving slide groove 3.

[0028] Working principle: This utility model is a cold-bent steel roll forming measuring instrument. When in use, the measuring ruler 1 is attached to the bottom surface of the roll forming. The magnetic strip 2 can be attracted to the bottom of the roll forming made of carbon steel or other materials. At this time, the measuring ruler 1 is fixed to the bottom surface of the roll forming. The length of the bottom edge of the roll forming can be measured by the length scale on the surface of the measuring ruler 1. Then, by moving the slider 4, the connecting column 5, the fixed plate 6, the rotating column 7 and the movable ruler plate 8 move together. The movable ruler plate 8 drives the rotating column 7 to rotate, so that the movable ruler plate 8 is parallel to the side of the roll forming and attached to the side surface of the roll forming. At this time, the angle of the side of the roll forming is measured by comparing the movable ruler plate 8 with the angle scale on the surface of the fixed plate 6.

[0029] The length of the side of the roller pattern can be measured by sliding the movable ruler 8 and through the scale on the surface of the movable ruler 8. It integrates the measurement of the bottom edge length, side length, and side angle of the roller pattern.
