Description

Technical Field

[0001] This utility model relates to the field of air preheater tube processing in boiler manufacturing units, specifically to a tooling for simultaneously cutting multiple tubes. Background Technology

[0002] In pipe processing, pipes often need to be cut to specific lengths. Traditional cutting methods typically involve cutting one pipe at a time, which is inefficient and consumes significant manpower and time. Furthermore, when multiple pipes need to be cut to the same size, the lack of an effective simultaneous fixing device makes it difficult to ensure consistent cutting accuracy for each pipe, affecting the quality of subsequent pipe use and installation compatibility. Therefore, there is an urgent need for a tooling system that can stably fix multiple pipes simultaneously and facilitate cutting to improve this situation. Utility Model Content

[0025] Specific Implementation Method Two: Combining Figures 1 to 4 This embodiment describes a sliding device 300 comprising two sliding steel pipes 7 and four steel pipe positioning assemblies 500. The two sliding steel pipes 7 are horizontally arranged opposite each other on the left and right sides of the main frame 100.

[0032] Working principle

[0033] Combination Figures 1 to 4 The working principle of this utility model's fixture for simultaneously cutting multiple pipes is explained as follows: First, based on the required cutting length of the steel pipes, the position of the rear main frame channel steel 9 is adjusted via the sliding device 300 to ensure a suitable position between the front main frame channel steel 2 and the rear main frame channel steel 9. Then, multiple pipes to be cut are sequentially placed into the fixture's main frame 100. Next, the two adjusting studs 4 and two adjusting nuts of the pipe clamping device 200 are operated to firmly fix the pipes in place by the clamping blocks 5. The pipe ends to be cut at the front main frame channel steel 2 are marked with the required dimensions. The cutting equipment (such as a toothed saw or a band saw) is started, and multiple pipes are simultaneously cut along the marked plane. Because the pipes are stably fixed, the cutting position is precisely determined, ensuring the dimensional accuracy and consistent cut quality of each pipe.

[0034] The working process of the tooling for simultaneously cutting multiple pipes according to this utility model is as follows:

[0035] I. Preparatory work:

[0036] First, place the tooling on a stable operating table and check whether each component is securely connected, whether the adjusting stud 4 of the pipe clamping device 200 can rotate smoothly, and whether the adjustment of the sliding device 300 is flexible and accurate.

[0037] II. Size Adjustment:

[0038] Determine the cutting length of the pipe according to the drawing requirements. Use a tool (wrench) to adjust the positioning clamp 3 so that the rear main frame channel steel 9 can move freely on the slide steel pipe 7, so that the rear main frame channel steel 9 and the front main frame channel steel 2 are adjusted to a suitable length distance. Then tighten the positioning clamp 3 with a wrench to fix the distance between the front main frame channel steel 2 and the rear main frame channel steel 9. Only in this way can the length error of multiple pipes after cutting be controlled within a very small range.

[0039] III. Pipe Placement and Fixing:

[0040] The steel pipes that meet the processing requirements are placed sequentially into the main frame 100 of the tooling, with one end of the pipe against the positioning back plate 6, ensuring that the pipe ends are neatly arranged and that each layer of pipes fits tightly. Then, the adjusting stud 4 of the pipe clamping device 200 is rotated simultaneously, causing the clamping block 5 to slowly press down until the pipe is firmly clamped. During the clamping process, the firmness of the fixation can be checked by visual observation or by slightly shaking the pipe. If there is any looseness, the adjusting stud 4 needs to be further adjusted and tightened.

[0041] IV. Cutting Operation:

[0042] Mark the pipe ends to be cut at both ends of the front main frame channel steel according to the required dimensions. Start the cutting equipment (such as a saw) and cut multiple pipes simultaneously along the plane where the markings are located until the cutting is complete. After cutting, turn off the cutting equipment first. After the cutting blade stops moving, loosen the screw of the clamping device, take out the cut pipe, and complete one round of cutting operations.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
