Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a fixed-length cutting device. Background Art

[0002] Pipes are one of the commonly used materials in industrial processing. When manufacturers produce and process pipes, they usually process the raw materials into one-piece pipes. In order to facilitate the storage and transportation of pipes, the pipes need to be initially cut after they are produced and formed to make the length of the pipes consistent. However, these pipes often need to be cut again according to actual conditions when they are used so that the length of the pipes can meet the use requirements. With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing.

[0003] For example, the patent document with the announcement number CN220541913U discloses a construction pipe length measuring device, including a support mechanism, a measuring mechanism is arranged at the inner bottom of the support mechanism, and an auxiliary measuring mechanism is arranged at one end of the measuring mechanism. By setting a measuring ruler, pulling it, and selecting the measuring distance by extending it on the support seat, the measuring scale corresponding to the selected measuring distance on the measuring ruler should be parallel to the port at the rear end of the receiving angle iron piece, and then the positioning bolt is passed through the connecting groove and extended into the fixing hole, and then the positioning bolt is rotated so that the positioning bolt and the fixing hole are threadedly locked, and the positioning bolt is threadedly locked with the fixing hole, and the position where the measuring ruler is set is clamped and fixed to enhance the stability of its measurement, ensure the uniformity of the required pipe measurement length, avoid the inaccuracy of the results of traditional manual handheld measurement, and effectively improve the use effect of the device and enhance its measurement efficiency.

[0004] Although the above technical solution can measure the length of the pipe during the cutting process, during use, when measuring and cutting pipes of different sizes, multiple measuring rulers need to be adjusted multiple times, and continuous cutting operations on pipes of various sizes cannot be achieved, which is not conducive to the assembly line measurement and cutting processing of the pipe, resulting in reduced efficiency of pipe cutting. Utility Model Content

[0007] The principle and advantage of this solution are: when cutting, the cutting material passes through the measuring part along the feeding direction, and the cutting material drives the measuring wheel to rotate during the movement. The measuring part detects the moving length of the cutting material according to the rotation of the measuring wheel. When the cutting material moves to the specified length, the cutting unit cuts the cutting material. After the cutting material is unloaded from the supporting groove, the cutting material moves again along the feeding direction. The measuring part measures the moving length of the cutting material again to prepare for the next cutting operation.

When the cutting material moves during the measurement process, the measuring part can support the cutting material, improve the stability of the cutting material during the measurement process, and ensure the accuracy of the cutting material length measurement result.

[0013] Preferably, as an improvement, a positioning block is provided at the bottom of the support groove, and the positioning block can move forward and backward along the extension direction of the support groove, so that the cut material can be fixed under the action of the positioning block after the measurement is completed, and the cut material is prevented from continuing to move forward under the action of inertia, thereby improving the accuracy of cutting the length of the cut material.

[0014] Preferably, as an improvement, the measuring wheel is located at the opening of the support groove near the cutting part, and the top of the measuring wheel is not lower than the bottom of the support groove, so that when the cutting material enters the measuring part, the cutting material can fully contact the surface of the measuring wheel, ensuring that the cutting material can drive the measuring wheel to rotate during the movement, thereby improving the accuracy of the cutting material length measurement.
