[0002] Cutting is a crucial step in the processing of stainless steel flexible metal hoses. Traditional cutting methods typically require straightening the metal hose beforehand to ensure accuracy and quality. However, existing cutting equipment has several problems during straightening and cutting operations, mainly in the following aspects:

[0003] 1. Unstable straightening effect: Existing straightening devices often result in unsatisfactory straightening effects when straightening metal hoses due to the lack of a precise control mechanism;

[0004] Second, the operation is complicated: existing cutting devices usually require multiple manual adjustments and calibrations, which are complicated and time-consuming, and cannot achieve fixed-length cutting.

[0005] 3. Poor applicability: Different specifications and materials of metal hoses require different straightening and cutting parameters. Existing equipment often lacks flexibility and cannot adapt to metal hoses of various specifications and materials, resulting in poor applicability of the equipment and the need for frequent replacement or adjustment of the equipment.

[0006] To address the shortcomings of existing technologies, this utility model provides a fixed-length cutting device for processing stainless steel metal hoses, aiming to solve the aforementioned problems. Utility Model Content

[0040] The length-fixing mechanism 2 includes a lead screw 21, a pair of guide rods 22, a nut 23, a guide block 24, and a drive motor 25. The two ends of the lead screw 21 are connected to a pair of side plates 11 via bearings. Both ends of the pair of guide rods 22 are connected to the pair of side plates 11, and each guide rod 22 has a scale line 221. The nut 23 is threadedly connected to the lead screw 21. The guide block 24 is connected to the outer periphery of the nut 23 and slidably connected to each guide rod 22. The drive motor 25 is mounted on a side plate 11 without a groove 111, and its output end passes through the side plate 11 and connects to one end of the lead screw 21.

[0041] A straightening mechanism 3 is provided on side plate 2 12 and is movably connected to side plate 11, and is used to straighten the hose before cutting it.

[0042] And a cutting mechanism 4, which is disposed on the top plate 13 and is used to cut the hose.

[0043] In this embodiment, the present invention designs a fixed-length mechanism 2, which, through the cooperation of a lead screw 21, a nut 23, a guide block 24, a graduated guide rod 22, and a drive motor 25, can precisely control the moving distance of the hose, thereby achieving fixed-length cutting of the hose. This solves the problem that traditional cutting methods cannot achieve fixed-length cutting, improves cutting efficiency and quality, and reduces material waste.

[0044] Furthermore, a groove 111 is also provided on the top of the guide block 24.

[0045] Specifically, the straightening mechanism 3 includes two pairs of straightening blocks 31, an auxiliary plate 33, and a cylinder 35; wherein,

[0046] An arc-shaped groove is provided at one end of each pair of straightening blocks 31 that is close to each other. Two straightening blocks 31 are fixedly connected to the side plate 11 and the guide block 24 respectively, and the other two straightening blocks 31 are slidably connected in the groove 111.

[0047] One end of the auxiliary plate 33 abuts against the back of the two movable straightening blocks 31, and the other end is connected to the output end of the cylinder 35.

[0048] To improve the structural stability of the straightening mechanism 3, in this embodiment, the straightening mechanism 3 further includes an elliptical reinforcing plate 34; the elliptical reinforcing plate 34 is connected to both the output end of the cylinder 35 and the auxiliary plate 33.

[0049] The above design avoids problems such as poor straightening effect or equipment damage caused by structural instability.

[0050] In order to provide a buffering effect during the straightening process and prevent the straightening block 31 from directly contacting the hose and causing scratches or damage to the hose surface, thus protecting the surface quality of the hose, in this embodiment, the straightening mechanism 3 further includes two pairs of flexible pads 32, each of which is fitted with the arc-shaped groove of the straightening block 31.

[0051] In this embodiment, the present invention introduces a straightening mechanism 3. By setting two pairs of straightening blocks 31, with arc-shaped grooves opened at their close ends, the shape of the metal hose can be better conformed to, and the hose can be straightened. The cylinder 35 pushes the auxiliary plate 33, which in turn drives the movable straightening blocks 31 to move, realizing the dynamic straightening of the hose. Compared with traditional straightening devices, the straightening effect is more stable and reliable, providing a better foundation for subsequent cutting and ensuring cutting quality. The design of a flexible pad 32 of a certain thickness makes the straightening mechanism 3 suitable for stainless steel metal hoses of various specifications and sizes, improving the flexibility and applicability of the device.

[0052] Specifically, the cutting mechanism includes a cutting blade 41, a cutting motor 42, and a cylinder 45; wherein,

[0053] The second cylinder 45 is located inside the top plate 13, and the output end of the second cylinder 45 is connected to the cutting frame 44.

[0055] The cutting motor 42 is located on the side of the cutting frame 44, and the output end of the cutting motor 42 is connected to one end of the rotating shaft 43.

[0056] It should be noted that, in order to facilitate the adjustment of the positions of cylinder 35 and cylinder 45, in this embodiment, the side plate 12 and the top plate 13 are also provided with a number of mounting holes 5 for the movable installation of cylinder 35 and cylinder 45.

[0057] In this embodiment, the present invention has several mounting holes 5 on the side plate 2 12, which allows the mounting position of the cylinder 35 to be adjusted according to the length of the hose cutting, so that the auxiliary plate 33 is subjected to more uniform force, and the straightening mechanism 3 is more stable; several mounting holes 5 are provided on the top plate 13, which allows the mounting position of the cylinder 45 to be adjusted according to the length of the hose cutting, so as to facilitate the precise cutting of the cutting blade 41.

[0058] Working principle: In use, first determine the fixed cutting length of the stainless steel metal hose, adjust the specific positions of cylinder 35 and cylinder 45, then start the drive motor 25. The motor shaft of the drive motor 25 rotates, driving the lead screw 21 to move, thereby causing the nut 23 to move linearly. The nut 23 drives the guide block 24 to move. According to the scale of the guide rod 22, the drive motor 25 is turned off when the guide block 24 moves to the preset distance (the fixed cutting distance at this time needs to be increased by the distance between the guide block 24 and the cutting blade 41). Then, place one end of the stainless steel metal hose into the straightening block 31 at the position of the guide block 24, and place the other end into the straightening block 31 on the side plate 12. Start cylinder 35. The piston rod of cylinder 35 causes the auxiliary plate 33 to move closer to the straightening block 31 until both ends of the stainless steel metal hose are clamped and fixed. Then, turn off cylinder 45. After straightening is completed, start the cutting motor 42 and cylinder 45 to continue cutting the stainless steel metal hose to the fixed length.

[0059] In summary, this utility model, through the combination of the above structures, can achieve straightening treatment before cutting stainless steel metal hoses to a fixed length, and is applicable to stainless steel metal hoses of different specifications and sizes.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
