Description

Technical Field

[0001] This utility model relates to the field of pipe bending and forming technology, and in particular to a pipe bending and forming calibration device. Background Technology

[0002] Chinese document CN118751719A discloses a pipe processing bending calibration device, including a calibration marking device. The calibration marking device includes a calibration stand, with two support wheels symmetrically connected to the left and right sides of the top of the calibration stand. Movable wheels are movably installed on the surface of the calibration stand at positions corresponding to the support wheels. The two movable wheels are connected and fixed together by a connecting plate. A calibration marking assembly is provided on the back of the top of the calibration stand. The calibration marking assembly includes a rail block, with a movable component at the top of the rail block. Two outer buckles are inserted into one side of the pipe. The movement of a bidirectional rack is controlled by the extension and retraction of the piston end of a second cylinder. The bidirectional rack and the teeth of the irregularly shaped gear plate cooperate to control the movement of two contact plates, thereby causing the outer buckles to support and abut against the inner wall of the pipe. This facilitates pipe positioning and prevents the pipe from shaking when rotating on the surfaces of the support wheels and movable wheels, ensuring the accuracy of pipe rotation measurement.

[0003] However, the aforementioned equipment, including some existing equipment, is focused on straightening bent pipes into a straight shape. The original process of bending pipes into shape requires calibrating the bent pipes with deviations to the "original design-required bending shape and size", rather than simply straightening the bent pipes. Therefore, there is an urgent need for a pipe bending and forming calibration device. Utility Model Content

[0004] The purpose of this invention is to provide a pipe bending and forming calibration device that can solve the problem that some existing devices rarely calibrate pipes to their original bending degree.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending and forming calibration device, comprising: The base has at least two sets of positioning holes through it; A fixing mechanism, located on top of the base, is used to fix the pipe. The calibration mechanism is located on the top of the base. The calibration mechanism includes a connecting plate, positioning rods and a vertical plate. The connecting plate is placed against the top of the base. Four sets of positioning rods are fixedly installed on the bottom of the connecting plate and are evenly distributed at the four corners of the bottom of the connecting plate. The four sets of positioning rods are inserted into the corresponding positioning holes. The vertical plate is fixedly installed on the top of the connecting plate.

[0006] Preferably, the calibration mechanism further includes a first electric push rod, a calibration block, and a handle. The first electric push rod is fixedly installed on the front outer surface of the upright plate. The free end of the first electric push rod passes through the upright plate and is fixedly installed with the calibration block. The handle is fixedly installed on the top of the upright plate.

[0007] Preferably, the fixing mechanism includes a U-shaped cover, a second electric push rod, an arc-shaped pressure plate, and a rubber pad. The U-shaped cover is fixedly installed on the top of the base, the second electric push rod is fixedly installed on the top of the U-shaped cover, the free end of the second electric push rod passes through the top of the U-shaped cover and is fixedly installed on the arc-shaped pressure plate, and a rubber pad is fixedly installed on the inner wall of the arc-shaped pressure plate.

[0008] Preferably, the bottom of the connecting plate is provided with a mounting groove, and a magnet is fixedly installed in the mounting groove, and the magnet is attracted to the base.

[0009] Preferably, two sets of fixing columns are fixedly installed on the top of the base.

[0010] Preferably, an L-shaped hanging plate is fixedly installed on one outer surface of the base, and a projector is fixedly installed on the L-shaped hanging plate.

[0011] Preferably, an anti-slip pad is fixedly installed on the bottom of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The pipe bending and forming calibration equipment, through the cooperation of the calibration mechanism and the fixing mechanism, can calibrate the pipe with bending deviation in the pipe bending and forming process, so that it bends to the proper arc. This solves the problem that some existing equipment focuses on correcting the bent pipe to a straight shape, while the original process of bending and forming the pipe requires calibrating the bent pipe with deviation to the "original design required bending shape and size", rather than simply straightening the bent pipe. This improves the practicality of the equipment.

[0013] (2) The pipe bending and forming calibration equipment can flexibly adjust the position of the calibration mechanism through the cooperation of the positioning hole and the positioning rod, so as to realize calibration at any position on the base, adapting to pipes with different degrees of bending. At the same time, under the action of the projector, the calibration degree can be accurately controlled by the projection, ensuring the effect of the equipment and facilitating the promotion and use of the equipment.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a pipe bending and forming calibration device, including a base 1, a fixing mechanism 4 and a calibration mechanism 3. At least two sets of positioning holes 2 are opened through the base 1. The fixing mechanism 4 is set on the top of the base 1 and is used to fix the pipe. Two sets of fixing columns 6 are fixedly installed on the top of the base 1. An L-shaped hanging plate 7 is fixedly installed on one side of the outer surface of the base 1. A projector 8 is fixedly installed on the L-shaped hanging plate 7. An anti-slip pad 9 is fixedly installed on the bottom of the base 1. The calibration mechanism 3 is located on the top of the base 1. The calibration mechanism 3 includes a connecting plate 31, positioning rods 32, and a vertical plate 33. The connecting plate 31 is placed against the top of the base 1. Four sets of positioning rods 32 are fixedly installed on the bottom of the connecting plate 31 and are evenly distributed at the four corners of the bottom of the connecting plate 31. The four sets of positioning rods 32 are inserted into the corresponding positioning holes 2. The vertical plate 33 is fixedly installed on the top of the connecting plate 31. Through the cooperation of the positioning holes 2 and the positioning rods 32, the position of the calibration mechanism 3 can be flexibly adjusted to achieve calibration at any position on the base 1, adapting to pipes with different degrees of curvature. At the same time, under the action of the projector 8, the calibration degree can be accurately controlled through projection, ensuring the effect of the equipment and facilitating the promotion and use of the equipment.

[0018] The calibration mechanism 3 also includes a first electric push rod 34, a calibration block 35, and a handle 36. The first electric push rod 34 is fixedly installed on the front outer surface of the upright plate 33. The free end of the first electric push rod 34 passes through the upright plate 33 and is fixedly installed with the calibration block 35. The handle 36 is fixedly installed on the top of the upright plate 33. The bottom of the connecting plate 31 has an installation groove, and a magnet 5 is fixedly installed in the installation groove. The magnet 5 is attracted to the base 1.

[0019] The fixing mechanism 4 includes a U-shaped cover 41, a second electric push rod 42, an arc-shaped pressure plate 43, and a rubber pad 44. The U-shaped cover 41 is fixedly installed on the top of the base 1, and the second electric push rod 42 is fixedly installed on the top of the U-shaped cover 41. The free end of the second electric push rod 42 passes through the top of the U-shaped cover 41 and is fixedly installed on the arc-shaped pressure plate 43. The rubber pad 44 is fixedly installed on the inner wall of the arc-shaped pressure plate 43. Through the cooperation of the calibration mechanism 3 and the fixing mechanism 4, the pipe with bending deviation in the pipe bending forming process can be calibrated so that it bends to the proper arc. This solves the problem that some existing equipment focuses on straightening the bent pipe into a straight shape, while the original process of bending the pipe requires calibrating the bent pipe with deviation to the "original design bending shape and size", rather than simply straightening the bent pipe. This improves the practicality of the equipment.

[0020] Working principle: The bent pipe is divided into a straight section and a bent section, with the bend point in the middle. The straight section of the pipe is inserted into the U-shaped cover 41 through two sets of fixing posts 6, so that the bend point is located between the two sets of fixing posts 6. Then, the free end of the second electric push rod 42 is extended, which drives the arc-shaped pressure plate 43 to move down until the pipe is fixed. Next, the projector 8 is started to project the original design shape of the pipe onto the base 1. Then, as needed, the handle 36 is held to lift the calibration mechanism 3 to adjust its position, and then it is lowered to a suitable position so that each positioning rod 32 is inserted into the corresponding positioning hole 2 to achieve positioning. Then, the free end of the first electric push rod 34 is extended, which drives the calibration block 35 to move and push the bent section of the pipe to bend and calibrate it to the original design shape.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
