Description
Technical Field
[0001] The utility model relates to the technical field of bent pipe measurement, in particular to a bent pipe shape detection tool. Background Art
[0002] The bending conditions of the water cooling plate bends are complex and varied, and the shape and size of the finished water cooling plate bends are common inspection contents.
[0003] At present, the common inspection process is to put the bent water cooling plate tube into a mold that matches its bending shape for comparison. If the water cooling plate tube can be completely placed in the mold, it means that it meets the requirements. Otherwise, it needs to be bent again. However, this mold can only detect the finished water cooling plate tube. For the inspection of a certain bending section during the bending process, the method of visual inspection of drawings or caliper measurement is generally used. The method of visual inspection of drawings has low measurement accuracy and is affected by external light conditions and visual angles. There are large differences in the inspections of different personnel. In addition, due to the size of the paper, a single A4 paper cannot fully cover the product, and multiple sheets of paper need to be spliced, which further reduces the accuracy. The caliper measurement cannot actually measure the length of the center line, and calculations need to be performed. The result is not intuitive. In addition, when measuring with a caliper, there is a phenomenon that some dimensions have virtual intersections, resulting in low measurement accuracy. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0024] The present embodiment provides a curved pipe shape detection tool, which is used to detect a planar curved pipe to be detected, wherein the curved pipe to be detected includes at least a first curved pipe and a second curved pipe that are connected and have different curvatures.
[0025] like Figure 1 As shown, the bend shape detection tool includes a mold plate 100. In this embodiment, the mold plate 100 is a flat plate with a simple structure and is easy to use. The mold plate 100 is provided with a verification groove that is consistent with the shape of the bend to be detected. The verification groove at least includes a first curved groove 1 and a second curved groove 2 that are connected. The first curved groove 1 is used to accommodate the first bend tube, and the second curved groove 2 is used to accommodate the second bend tube. The curvature of the first curved groove 1 is different from the curvature of the second curved groove 2. The mold plate 100 is also provided with a first extended straight groove 6. The head end of the first extended straight groove 6 coincides with the connection between the first curved groove 1 and the second curved groove 2. The first extended straight groove 6 extends straightly from its head end. The center line of the first extended straight groove 6 is tangent to the center line of the first curved groove 1, and the center line of the first extended straight groove 6 is tangent to the center line of the second curved groove 2.
[0026] In the process of bending pipes, straight pipes are generally used as raw materials, and the straight pipes are bent in sequence and in steps to finally form finished products. Taking the production of the above-mentioned bent pipe to be tested as an example, the first bent pipe and the second bent pipe are bent in sequence. When the first bent pipe of the bent pipe to be tested is bent and the second bent pipe is not bent, the bent pipe to be tested as a whole can be matched with the verification groove and the first extended straight groove 6, so that the first bent pipe is embedded in the first curved groove 1, and the straight pipe connected to the first bent pipe and not bent is embedded in the first extended straight groove 6, so that the bending effect of the first bent pipe can be easily verified to ensure that the bending meets the process requirements, and then the second bent pipe is bent. In this embodiment, the first extended straight groove 6 is set to accommodate the unbent straight pipe, so that the bent pipe to be tested as a whole, which only bends the first bent pipe, is tested.
[0027] Similarly, when the bent pipe to be inspected includes multiple first bent pipes and second bent pipes that are circularly connected, multiple first extended straight grooves 6 can realize the detection of the contour shape of the bent section formed by each bending step. The proofreading process is simple, and the results are intuitive and accurate, which can ensure that the bending of each section of the pipe can be checked in time to avoid rework, thereby effectively improving production efficiency.
[0028] like Figure 1 As shown, the first curved groove 1, the second curved groove 2, the third curved groove 3 and the fourth curved groove 5 are all arc-shaped in the length direction. The cross-sectional shapes of the first curved groove 1, the second curved groove 2, the third curved groove 3, the fourth curved groove 5, the first extended straight groove 6 and the second extended straight groove 7 are the same. Specifically, the cross-sectional shapes of the first curved groove 1, the second curved groove 2, the third curved groove 3, the fourth curved groove 5, the first extended straight groove 6 and the second extended straight groove 7 are semicircular, so as to verify the tested curved pipe with a circular cross-section.
[0029] In this embodiment, one end of the third curved groove 3 away from the straight groove 4 is connected to one end of the second curved groove 2 away from the first curved groove 1. The mold plate 100 is also provided with a third extended straight groove 8, the head end of the third extended straight groove 8 coincides with the connection between the third curved groove 3 and the second curved groove 2, the center line of the third extended straight groove 8 is tangent to the center line of the second curved groove 2, and the center line of the third extended straight groove 8 is tangent to the center line of the third curved groove 3. The third extended straight groove 8 serves as a receiving groove for the unbent and straight pipe fitting, so that the bent section (second bent pipe) of the bent pipe to be tested can be aligned with the second curved groove 2 to determine whether it meets the contour of the second curved groove 2.
[0030] In this embodiment, the inspection groove further includes a third curved groove 3, a straight groove 4 and a fourth curved groove 5 connected in sequence, and a second extended straight groove 7 is further provided on the mold plate 100, the head end of the second extended straight groove 7 coincides with the connection between the fourth curved groove 5 and the straight groove 4, the second extended straight groove 7 extends in the same direction as the straight groove 4, the center line of the second extended straight groove 7 is tangent to the center line of the fourth curved groove 5, and the center line of the second extended straight groove 7 coincides with the center line of the straight groove 4. The second extended straight groove 7 extends in the same direction as the straight groove 4, and serves as a receiving groove for the unbent and straight pipe fitting, so as to facilitate the bent section of the tested bent pipe to be aligned with the third curved groove 3, and to determine whether it meets the contour of the third curved groove 3.
[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the tail end of the first extended straight groove 6 passes through the edge of the mold plate 100, the tail end of the second extended straight groove 7 passes through the edge of the mold plate 100, and the tail end of the third extended straight groove 8 passes through the edge of the mold plate 100. In other words, when the length of the unbent straight tube is long, the tail end of the first extended straight groove 6, the second extended straight groove 7 or the third extended straight groove 8 can extend out of the mold plate 100 to avoid interference causing the straight tube to tilt and affect the calibration of the bent section.
[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
