Description

Technical Field

[0001] This utility model belongs to the field of pipe processing technology, and specifically relates to a multifunctional simple pipe bending device. Background Technology

[0002] Mechanical equipment has a variety of internal structures and external surface shapes. Due to design requirements and ease of assembly, it is necessary to transmit power media, such as compressed gas or hydraulic oil, through small metal pipes. Small-diameter metal pipes need to be routed at different angles. Therefore, it is necessary to perform multi-angle bending processing on the metal pipes to facilitate assembly, save equipment space, and improve aesthetics.

[0003] Due to the personalized requirements of equipment structure and performance, metal tubes need to be flexibly bent according to the equipment structure to meet the requirements of multiple angles, different lengths, and planar and three-dimensional orientations of the metal tubes. The bending angle is usually 90 degrees. Considering the assembly size requirements and the actual use of the metal tubes to transmit pressurized power media, the tube bending device must ensure processing accuracy and reduce wear on the tube wall during processing. At the same time, it must meet the requirements of simple structure, flexible adjustment of processing size, and convenient operation. Therefore, a simple tube bending device that can guarantee processing quality is needed.

[0004] Patent (CN201720298U) discloses an extrusion-type pipe bending device, which is designed with two extrusion rollers. The outer edge of the extrusion rollers is provided with grooves corresponding to the cross-section of the profile. The extrusion rollers are mounted on a support frame by pins. A semi-circular extrusion disc is designed on the upper part of the extrusion rollers. The outer edge of the semi-circular extrusion disc is designed with grooves corresponding to the cross-section of the profile. The pipe is bent by the mutual extrusion of the extrusion disc and the extrusion rollers.

[0005] Most existing pipe bending devices are complex in structure, cumbersome to operate, and lack flexibility. For pipe bending devices that meet the requirements of multi-angle three-dimensional bending, purely manual structures are generally bulky and complex, while purely electric drives cannot perform processing activities in the event of a power outage. The purchase, use, and maintenance costs of these devices are high, and troubleshooting is difficult when malfunctions occur. Furthermore, the processing accuracy decreases after prolonged use, failing to guarantee the required processing precision. Therefore, there is an urgent need to develop a pipe bending device with a simple structure capable of multi-angle and multi-dimensional bending. Utility Model Content

[0046] The horizontal base 1 includes a long side and a short side, which are perpendicular to each other and form an L-shape.

[0047] A size block 6 is installed at one end of the long side (the end away from the short side) of the horizontal base 1;

[0048] The dimension block 6 comprises a plurality of continuously arranged equal-width dimension plates; the dimension plates are rotatably connected to the horizontal base 1, and the dimension plates are perpendicular to the long side of the horizontal base 1; wherein the dimension plates abut against each other. For example, the dimension plates are cuboids of fixed dimensions. End 0 is the end of the dimension block 6 closest to the metal tube (i.e.,...). Figure 1 (At the lower end of the tube), the length of the metal tube after each bend can be adjusted by rotating the size plate.

[0049] Multiple limiting blocks 2 are spaced apart on the long side of the horizontal base 1; the multiple limiting blocks 2 are located on a straight line;

[0050] A primary pipe bending mechanism 31 is installed on the long side of the horizontal base 1;

[0051] The single-bending mechanism 31 includes a metal platform, a handle 32, a rotating wheel 33, a bending clamp 34, and a roller 35;

[0052] The metal platform is connected to the horizontal machine base 1;

[0053] The rotating wheel 33 is rotatably connected to the metal platform;

[0054] The handle 32 and roller 35 are fixedly connected to the rotating wheel 33. For example, the handle 32 and the rotating wheel 33 are connected by threads. The handle 32 drives the rotating wheel 33 to rotate, and the rotating wheel 33 drives the roller 35 to rotate. The roller 35 can rotate around its own central axis to apply extrusion force to the metal tube.

[0055] Two bending clamps 34 are fixedly mounted at a distance from the top of the metal platform; the two bending clamps 34 are axially symmetrical. For example, each bending clamp 34 is a cylinder with a quarter-circle horizontal cross-section. The arc surfaces of the two bending clamps 34 are arranged opposite each other.

[0056] The bending clamp 34 is arc-shaped, conforming to the shape of the metal tube to ensure that the metal tube does not deform when bent.

[0057] like Figure 2 As shown, the vertical base 41 is slidably connected to the short side of the horizontal base 1; a secondary pipe bending mechanism 42 is installed on the vertical base 41. When the vertical base 41 is placed vertically, the vertical base 41 is perpendicular to the plane of the horizontal base 1.

While saving production costs, it greatly facilitates the processing and assembly of mechanical equipment. It can meet the multi-angle and multi-dimensional bending processing needs of small-diameter metal pipes, and the bending length of each section can be flexibly adjusted. At the same time, it ensures the processing accuracy of metal pipes and reduces the wear of metal pipes during processing.

[0059] The single-bending mechanism 31 controls the bending length, angle, and angular direction of the metal tube in one bend. It uses the limiting block 2 and the size block 6 to fix the metal tube, and uses the size block 6 and the size hole 5 to adjust the length of the metal tube in one bend.

[0060] The secondary bending mechanism 42 is located below the hinge 45 on the vertical base 41. It controls the length, angle and direction of the secondary bending of the metal tube.

[0063] In some embodiments, the limiting block 2 is a cylinder with an annular protrusion in the middle, one end of which is connected to the horizontal base 1.

[0068] In some embodiments, the slide is provided with a plurality of positioning holes;

[0069] The bottom of the vertical base 41 is provided with a positioning component with holes;

[0070] The vertical base 41 is positioned within the slide groove by a position adjustment pin 7. The position adjustment pin 7 is inserted sequentially into the positioning component and the positioning hole, thereby adjusting and fixing the position of the vertical base 41.

[0071] In some embodiments, the vertical base 41 includes a first base and a second base;

[0072] The first base and the second base are rotatably connected, and the second base is located above the first base;

[0073] The secondary pipe bending mechanism 42 is mounted on the first base.

[0074] like Figure 3 As shown, in some embodiments, the first base and the second base are connected by a hinge 45. The hinge 45 designed on the vertical base 41 facilitates the opening, closing, and erection of the vertical base 41, reducing the space occupied by the pipe bending device.

[0075] The hinge 45 is located on the back of the vertical base, above the secondary bending mechanism 42, which facilitates the opening, closing and erection of the vertical base 41.

For example, the triple-bending mechanism 43 is connected to the adjustment groove via bolts. The triple-bending mechanism 43 can be connected to different adjustment grooves depending on the triple-bending dimensions of the metal tube.

[0080] The triple bending mechanism 43 is located above the hinge 45 of the vertical base 41.

[0081] The secondary bending mechanism 42 moves horizontally with the vertical machine base 41 to control the length, angle and direction of the secondary bending of the metal tube. The bending principle is the same as that of the primary bending mechanism 31. The length adjustment bar 44 on the vertical machine base 41 can adjust the length of the third bending of the metal tube. Together with the tertiary bending mechanism 43, it controls the length, angle and direction of the third bending, and completes the multi-angle and multi-dimensional processing of the metal tube.

[0082] In some embodiments, the primary bending mechanism 31, the secondary bending mechanism 42, and the tertiary bending mechanism 43 have the same structure.

[0083] This utility model of pipe bending device can realize multi-angle and multi-dimensional bending of metal pipes, accurately control the bending angle and bending section length, and the bending clamp and roller can ensure that the metal pipe does not deform during bending and reduce wear on the metal pipe, thus ensuring processing quality and improving overall processing efficiency.

[0084] The working principle of this pipe bending device is as follows:

[0085] When bending a metal tube in one pass, the metal tube is placed on a horizontal machine base 1, with one end of the metal tube fixed against the dimension block 6 at dimension 0. The horizontal machine base 1 is designed with dimension holes 5, which can flexibly adjust the position of the primary bending mechanism 31. Limiting blocks 2 and bending clamps 34 are used for limiting. The length of the metal tube to be bent in one pass is adjusted by rotating the dimension block 6 or adjusting the position of the primary bending mechanism 31. Rotating the handle 32 drives the rotating wheel 33 to rotate, and the roller 35 applies pressure to the metal tube to bend it. The bending clamp 34 is arc-shaped. Under the action of rotating wheel 33 and pressing roller 35, the metal tube is bent into the required shape. Angle lines 36 are designed on the rotating wheel 33 to control the bending angle of the metal tube in one pass, ensuring processing accuracy and completing one bending operation. The roller 35 can rotate on its own when rotating with the rotating wheel 33, reducing wear on the metal tube and ensuring processing quality.

[0086] The secondary bending mechanism 42 is used to perform a secondary bending. The bending clamp 34 in the secondary bending mechanism 42 is used to limit and fix the metal tube. The length of the metal tube for secondary bending is precisely adjusted by the slide groove and the position adjustment pin 7. The bending clamp 34 is used to limit the bending. The handle 32 and the rotating wheel 33 are rotated. The roller 35 is used to squeeze the metal tube to complete the secondary bending.

[0087] The metal tube is bent three times using the three-bending mechanism 43, the length of the metal tube is adjusted using the length adjustment bar 44, the bending clamp 34 is used for limiting, the handle 32 and the rotating wheel 33 are rotated, and the roller 35 is used to squeeze the metal tube to complete the three-bending.

[0088] Although the present invention 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; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
