[0030] Embodiment

[0031] The embodiment will be specifically described below in combination with the drawings:

[0032] The embodiment provides a pipe limiting device for a pipe bending machine, as shown in Figures 1-4 The pipe limiting device comprises:

[0033] The mounting seat 1 is mounted on one side of the pipe bending machine 8.

[0034] The adjusting assembly comprises an adjusting slider 3 movably arranged on the mounting seat 1 along the length direction of the mounting seat 1 and a driving assembly 4 connected to the adjusting slider 3. The adjusting slider 3 is kept in a self-locking state after changing position under the driving of the driving assembly 4 and remains static.

[0035] The limiting baffle 2 is fixedly arranged on the adjusting slider 3 and faces the press-bending mechanism 81 of the pipe bending machine 8. The limiting baffle 2 is used for limiting and blocking the pipe material extending from one side of the press-bending mechanism 81.

[0036] The measuring structure comprises a scale ruler 5 arranged on the mounting seat 1 along the length direction of the mounting seat 1 and an indicating piece 6 arranged on the adjusting slider 3 and pointing to the scale ruler 5. The indicating piece 6 is used for measuring the distance length of the pipe material extending from the press-bending mechanism 81 to the limiting baffle 2 in cooperation with the scale ruler 5.

[0037] The above embodiment is the core technical scheme of the present embodiment. Before the pipe bender 8 is subjected to the bending process, according to the bending length requirement of the pipe, the limiting baffle 2 is first moved and adjusted in position on the mounting seat 1 through the adjusting slide block 3, so as to meet the requirement of the pipe for different bending lengths. The pipe waiting to be bent part extends from the bending mechanism 81 to the side of the limiting baffle 2. The length of the pipe is directly determined by the rigid abutment of the limiting baffle 2 and the pipe, and the limiting baffle 2 plays a limiting role on the pipe. All pipes take the limiting baffle 2 as a physical stop point, ensuring the consistency of the starting position and length of the pipe bending, and achieving the purpose of unifying the bending reference. Then, through the cooperation of the indicating part 6 and the scale ruler 5, the length of the pipe extending from the bending mechanism 81 to the limiting baffle 2 can be accurately measured and read, that is, the bending length of the pipe is directly quantified. This design solves the size deviation problem caused by traditional visual inspection or experience operation. By adopting the technical scheme, the pipe bender 8 can realize length limiting and distance measuring of the pipe to be bent with the aid of the limiting device, better control product quality and optimize process, and can assist the pipe bender to realize L-shaped, U-shaped, Z-shaped and other different angle bending process of the pipe. It is efficient to adapt to the production of multiple specifications of pipes, and is beneficial to improve the processing efficiency.

[0038] As shown in Figure 2 The mounting seat 1 is provided with a guide rail 11 extending in the same direction, and the adjusting slide block 3 is provided with a guide groove connected to the guide rail 11. The cooperation of the guide rail 11 and the guide groove plays a guiding role in the movement of the adjusting slide block 3. The adjusting slide block 3 has a connecting plate 31 extending in a direction perpendicular to the length direction of the guide rail 11. A gap is left between the connecting plate 31 and the mounting seat 1. The limiting baffle 2 is fixed on the connecting plate 31 in a vertical manner. The extension direction of the limiting baffle 2 is perpendicular to the extension direction of the guide rail 11. In this way, the limiting baffle 2 is arranged opposite to the bending mechanism 81. The pipe extending from the side of the bending mechanism 81 is just blocked by the limiting baffle 2. The rigid block of the limiting baffle 2 forms a physical stop point, ensuring the consistency of the extension bending length of the pipe each time, and reducing the rework rate caused by size deviation.

[0039] Further preferably, the indicating part 6 is a scale indicating arrow arranged on the side wall of the adjusting slide block 3 and pointing to the scale mark. The scale indicating arrow is located on the side of the limiting baffle 2 away from the elbow mechanism. The distance displayed by the scale indicating arrow to the scale ruler 5 is the distance of the pipe extending from the bending mechanism 81 to the limiting baffle 2, which is accurate and reliable.

[0040] As shown in Figure 4As shown, the limiting baffle 2 and the adjusting slider 3 are connected to form a limiting step 32. At least one support adjustment structure 7 is provided at the limiting step 32, abutting against the lower side of the pipe. The support adjustment structure 7 is height-adjustable along the height direction of the limiting baffle 2. Specifically, the support adjustment structure 7 includes a pad 71 fixed on the limiting step 32 and an adjusting bolt 72 threadedly connected to the pad 71. The advantage of this design is that the adjusting bolt 72 provides support contact with the lower side of the pipe (see attached diagram). Figure 1 In this context, A represents the pipe material. When bending pipes of different diameters, the contact height between the pipe and the adjusting bolt will change due to the change in pipe diameter. At this time, it is necessary to rotate the adjusting bolt to adjust its height to adapt to different specifications of pipes, thereby ensuring the flatness and balance of the pipe against the limit baffle and improving the bending quality of the pipe.

[0041] The following is combined Figures 1-4 The specific configuration methods for the driver components are explained in detail:

[0042] The drive assembly 4 includes a transmission nut 41 disposed at the bottom of the connecting plate 31 of the adjusting slider 3, an adjusting screw 42 extending along the length of the mounting base 1 and connected to the transmission nut 41, and a positioning structure disposed on the mounting base 1 and forming a positioning rotational engagement with the adjusting screw 42. More preferably, the positioning structure includes two positioning seats 43 disposed opposite to each other on the mounting base 1 and two positioning holes corresponding to the two positioning seats 43. The adjusting screw 42 has two rotating ends respectively rotatably connected to the two positioning holes, one of which passes through the outer side of one of the positioning seats 43. The two positioning seats 43 provide a positioning rotation function for the adjusting screw 42. With this structure, the limiting baffle 2 adjusts the distance between the adjusting slider 3 and the pipe bending machine 8 by adjusting the displacement movement of the adjusting slider 3 on the mounting base 1. The adjustment slider 3 uses a screw drive to achieve displacement adjustment. Specifically, the adjustment screw 42 and the transmission nut 41 work together to drive the adjustment slider 3 to move along the guide rail 11. This design has the following advantages: First, this screw drive converts rotational motion into linear motion of the adjustment slider 3, thereby precisely adjusting the displacement position of the limit baffle 2. Combined with the millimeter-level reading of the scale 5, it achieves high-precision positioning adjustment. Second, this screw drive relies entirely on friction to achieve self-locking, eliminating the need for an additional braking device. This gives the adjustment slider 3 and the limit baffle 2 static self-locking capability, which can resist the displacement of the limit baffle 2 caused by pipe vibration and pushing. It has good installation stability and convenient adjustment operation, making it well-suited for pipe bending processes that require frequent adjustments and have strict stability requirements.

[0043] In the present embodiment, although the driving assembly 4 is preferably in the form of a threaded screw rod, it is obvious that other different arrangements can be provided as an alternative to the driving assembly described above, which is a gear driving assembly provided on the mounting base 1 and comprising a worm gear and a worm provided in rotation on the mounting base 1 and a rack bar extending along the length of the mounting base 1 and connected to the adjusting slide 3, the rack bar being engaged with the worm gear, the worm being coaxially linked to an operating lever, which can be driven by the operator to rotate the worm gear and the worm, thereby driving the rack bar to move the adjusting slide 3 in a straight line. It can be seen that the driving assembly 4 in the form of a worm gear and worm combined with a rack can also drive the adjusting slide 3 to move along the guide rail 11, thereby adjusting the position of the limiting baffle to adapt to the bending requirements of pipes of different lengths. The technical core of this design lies in the efficient combination of the force amplification and self-locking characteristics of the worm gear and worm with the straight line movement of the rack, so as to achieve displacement adjustment of the adjusting slide and the limiting baffle, which is convenient to operate. Those skilled in the art can select the specific structure of the driving assembly according to the above description, and other equivalent embodiments of the driving structure will not be described here.

[0044] Obviously, the above embodiments are only examples for the purpose of clarity and are not intended to limit the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or modifications. It is not necessary and impossible to enumerate all the embodiments. The obvious changes or modifications derived therefrom are still within the protection scope of the present application.
