[0018] The technical effects and advantages of this utility model are as follows:
[0019] 1. This utility model, by providing a fixed plate, requires the hose to be flattened by pressure rollers one and two when bending different hoses. The hose is then placed between pressure rollers one and two, and supported by two limiting plates. The rotary motor is turned on, driving the forward and reverse lead screws to rotate, which in turn drives the two threaded collars to move relative to each other. This causes the two moving blocks to slide in the square groove, while the sliding rod slides in the limiting groove, providing stable support for the movement of the moving blocks. This facilitates the relative movement of the two fixed plates, limiting the hoses of different sizes and preventing them from shifting during the bending process, which would affect the bending efficiency and accuracy of the hoses.
[0020] 2. This utility model, by providing an adjustment component, allows for bending of the hose within the bending groove. With the support of a bracket, the adjustment motor is activated, driving the gear to rotate and move under the meshing action of the gear plate. This, in turn, moves the bending plate at one end of the connecting column downwards. The bending plate then drives the semi-I-shaped slider to slide on the outer wall of the I-shaped slide rod, providing stable support for the movement of the bending plate. The limiting rod slides within the limiting groove as the adjustment motor moves, limiting the movement of the adjustment motor. This facilitates height adjustment of the bending plate and enables the bending of the hose within the bending groove. Attached Figure Description

[0036] The drive mechanism is located in the middle of the two threaded collars 304 and is used to drive the two threaded collars 304 to move relative to each other.
[0037] The drive mechanism includes a rotary motor 301. The bottom end of the rotary motor 301 is fixedly connected to the left side of the worktable 1 via a fixing plate. The transmission end of the rotary motor 301 is fixedly connected to a positive and negative lead screw 306. The outer walls of the positive and negative lead screw 306 near both ends are movably sleeved with limit plates 302. The top ends of the two limit plates 302 are fixedly connected to the bottom end of the worktable 1 near the left and right sides.

[0039] In this embodiment, as Figure 1-3As shown, with the support of the two limiting plates 302, the rotary motor 301 is turned on, which drives the positive and negative lead screws 306 to rotate, thereby driving the two threaded collars 304 to move relative to each other, and driving the two moving blocks 305 to slide in the square slide groove 101. At the same time, the slide rod 303 slides in the limiting groove 103, providing stable support for the movement of the moving blocks 305.
[0040] Example 2
[0041] The difference from Embodiment 1 is that this embodiment discloses that: the adjustment component 9 includes a support rod 906, the top and bottom ends of the support rod 906 are fixedly connected to the top and bottom ends of the inner wall of the bracket 8, a toothed plate 902 is fixedly connected to the left side of the support rod 906, a gear 904 meshes with the outer wall of the toothed plate 902, a connecting column 909 is movably sleeved in the middle of the gear 904 through a bearing, the front end of the connecting column 909 is fixedly connected to the bending plate 10, a semi-I-shaped slider 908 is fixedly connected to the rear side of the bending plate 10 near the connecting column 909, an I-shaped slide rod 907 is slidably connected to the inner wall of the semi-I-shaped slider 908, and the rear side of the I-shaped slide rod 907 is fixedly connected to the front side of the support rod 906.
[0042] A limiting groove 905 is provided on the rear side of the support rod 906. A limiting rod 903 is slidably connected to the inner wall of the limiting groove 905. One end of the limiting rod 903 is fixedly connected to the outer wall of the connecting column 909. An adjusting motor 901 is fixedly connected to the middle of the limiting rod 903. The transmission end of the adjusting motor 901 is fixedly connected to the rear side of the gear 904.
[0043] A first slide groove 801 is provided on the front side of the bracket 8 near the left end, and a second slide groove 802 is provided on the front side of the bracket 8 near the first slide groove 801. The outer wall of the connecting column 909 is slidably connected in the first slide groove 801, and the outer wall of the semi-I-shaped slider 908 is slidably connected in the second slide groove 802.
[0044] In this embodiment, as Figure 1-2 and Figure 4-5 As shown, when the adjusting motor 901 is turned on, the gear 904 rotates and moves under the meshing action with the toothed plate 902, which in turn drives the bending plate 10 at one end of the connecting column 909 to move downward. The bending plate 10 drives the semi-I-shaped slider 908 to slide on the outer wall of the I-shaped slide rod 907, providing stable support for the movement of the bending plate 10. The limiting rod 903 slides in the limiting groove 905 as the adjusting motor 901 moves, limiting the movement of the adjusting motor 901.
[0045] The working principle of this utility model is as follows: When bending different types of hoses, the hoses need to be flattened by pressure roller 4 and pressure roller 5. The hoses are then placed between pressure roller 4 and pressure roller 5. Supported by two limiting plates 302, the rotary motor 301 is turned on, driving the forward and reverse lead screws 306 to rotate. This, in turn, causes the two threaded collars 304 to move relative to each other, and the two moving blocks 305 to slide within the square sliding groove 101. Simultaneously, the sliding rod 303 slides within the limiting groove 103, providing stable support for the movement of the moving blocks 305. This, in turn, causes the two fixed plates 6 to move relative to each other, limiting the movement of hoses of different sizes. When bending the hose in the bending groove 102, under the support of the bracket 8, the adjusting motor 901 is turned on, which drives the gear 904 to rotate and move under the meshing action with the toothed plate 902, thereby driving the bending plate 10 at one end of the connecting column 909 to move downward. The bending plate 10 drives the semi-I-shaped slider 908 to slide on the outer wall of the I-shaped slide rod 907, providing stable support for the movement of the bending plate 10. The limiting rod 903 slides in the limiting slide groove 905 as the adjusting motor 901 moves, limiting the movement of the adjusting motor 901, thereby adjusting the height of the bending plate 10 and bending the hose in the bending groove 102.
[0046] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
