Description

Technical Field

[0001] The utility model relates to the technical field of pipe bender, in particular to a multi-angle pipe bender. Background Art

[0002] In the existing pipe bending process, there is a problem that the pipe is not firmly fixed, which causes the pipe to shift during the bending process, making it impossible to accurately control the bending angle, thereby affecting the quality of the finished product and increasing the error rate. Utility Model Content

[0003] The utility model aims at the technical problems existing in the prior art and provides a multi-angle pipe bender to solve the problem that the pipe is not firmly fixed, resulting in the pipe shifting during the bending process, making it impossible to accurately control the bending angle.

[0004] The utility model solves the above technical problems with the following technical solutions: a multi-angle pipe bender, comprising:

[0005] A frame and a forming block arranged on the frame, wherein a forming groove for accommodating a pipe is provided on a side wall of the forming block;

[0006] A holding component located on one side of the forming block and holding the pipe against the forming groove;

[0007] The driving member is arranged on the pressing assembly and is used to drive the pressing assembly pressed against the pipe to move along the path of the forming groove, so that the pipe presents an outer contour consistent with the path of the forming groove.

[0008] The beneficial effects of the utility model are:

[0009] 1) The pipe bender effectively wraps and holds the pipe through the built-in contour of the forming groove and the holding component, ensuring that the pipe is in a fixed position and angle during the forming process, avoiding displacement, and improving the stability and accuracy of the bending process. While the holding component has a limiting effect, it cooperates with the linkage of the driving part to move along the path of the forming groove to deform the pipe, ensuring that the pipe is accurately bent and presents the expected shape and contour, effectively realizing the deformation processing of the pipe.

[0010] 2) In summary, through the combined application of the forming groove, the holding assembly and the driving part, the pipe is effectively limited to ensure that the pipe will not move during the bending process, thereby achieving accurate bending processing. By effectively limiting the position and controlling the deformation of the pipe, the movement of the pipe can be reduced, thereby greatly reducing the product failure rate and improving product quality and work efficiency.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the forming groove is composed of three sections, namely, a straight groove one, a rounded groove, and a straight groove two, which are connected in sequence, wherein the straight groove one is opened on one side of the forming block, the straight groove two is opened on the other side of the forming block, and the side wall of the straight groove two is adjacent to the side wall of the straight groove one, and the rounded groove is opened at the angle formed by the straight groove one and the straight groove two, so that the path formed by the three sections of the forming groove is in an arc shape.

[0013] Furthermore, the shape of the groove opening of the forming groove is set to be semicircular.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the semicircular notch of the forming groove can fit more closely with the surface of the pipe, effectively reducing the gap and friction, helping to protect the appearance and surface quality of the pipe, and avoiding damage to the pipe during the deformation process. The better fit reduces the deviation and instability during the deformation of the pipe, and can provide better adaptability, thereby achieving a more precise, efficient and reliable pipe deformation processing process.

[0015] Furthermore, the forming block is provided with a baffle on one side of the forming groove, and a avoidance groove is provided on the side of the baffle facing the forming groove, and the avoidance groove is distributed in a mirror-symmetrical manner with the forming groove.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that the baffle is used to limit the end of the pipe to prevent the non-stressed end of the pipe from warping, making it impossible for the pipe to deform and bend, further improving the deformation processing process of the pipe. The mirror-symmetrical layout of the forming groove and the avoidance groove makes the baffle bear a balanced force when blocking the pipe, which is more fitting and avoids the formation of a gap between the pipe and the avoidance groove, resulting in slight warping of the non-stressed end of the pipe.

[0017] Furthermore, the driving member includes a driving member 1 that is driven by displacement along the axial direction of the straight groove 1 and a driving member 2 that is driven by displacement along the radial direction of the straight groove 1, and the driving directions of the driving member 1 and the driving member 2 are different.

[0018] Furthermore, the drive 1 includes a handle, a rocker, a support, a screw rod, a nut, a connecting plate, a slide rail, and a slider. The support is fixed on the frame, and the two ends of the screw rod are rotatably connected to the support through a rotating shaft. The rocker is fixed to one end of the screw rod, the handle is sleeved on one end of the rocker, the nut is screwed on the outside of the screw rod through a thread, one side of the connecting plate is fixed on the nut, and the other side of the connecting plate is fixed on the slider, the slide rail is fixed on the top of the support, and the slider slides on the slide rail.

[0019] Furthermore, the second drive includes a cylinder.

[0020] Furthermore, the holding assembly includes a roller, a support rod, and a cross arm, one end of the cross arm is rotatably connected to the connecting plate via a rotating shaft, and the other end of the cross arm is rotatably connected to the driving end of the cylinder via a rotating shaft, the support rod is fixed on the side wall of the cross arm close to the cylinder, and the roller is rotatably connected to the support arm via a rotating shaft.

[0021] The beneficial effect of adopting the above further scheme is that, first, the pipe is inserted between the forming groove and the avoidance groove, so that it is located in the straight groove one, and one end is located between the forming groove and the avoidance groove, then, the cylinder moves along the radial direction of the straight groove one, driving the cross arm to rotate toward the pipe with the connecting end of the connecting plate and the cross arm as the rotation axis, and the cantilever drives the roller to rotate toward the pipe through the support rod, so that the roller contacts and abuts against the pipe, and the pipe is limited and fixed;

[0022] At the same time, the operator holds the handle to make the handle move in a circle with the screw as the rotation axis. The handle drives the screw to rotate through the rocker, and the nut moves along the screw. The nut drives the connecting plate and the slider to slide on the slide rail. The connecting plate drives the cross arm, the support rod and the roller to move axially along the straight groove, so that the roller is pressed on the pipe and rolls along the axial direction of the straight groove. In addition, with the support of the cylinder drive, the roller draws an arc-shaped trajectory during the rolling process on the pipe, which coincides with the path of the fillet groove, so that the roller is against the other end of the pipe and presses the other end into the second straight groove, thereby realizing the arc bending process of the pipe.

[0023] Furthermore, a limiting groove is provided on the outer side of the roller along the circumference of the roller.

[0024] Furthermore, the shape of the notch of the limiting groove is set to be semicircular and has the same radial dimension as the forming groove.

[0025] The beneficial effect of adopting the above-mentioned further scheme is that the limit control of the roller is enhanced. At the same time, through the semicircular groove design and the consistency with the forming groove, the accuracy of the processing process and the safety of the pipe are effectively guaranteed. The design of the limit groove on the outside of the roller makes it more effective to limit the movement range of the roller during the processing process, and moves according to a specific trajectory, thereby improving the stability and accuracy of the pipe processing. The limit groove adopts a semicircular design and has the same size as the forming groove, which can better fit the surface of the pipe and reduce friction and the risk of damage to the pipe.

DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] In the existing pipe bending process, there is a problem of loose fixation of the pipe, which causes the pipe to shift during the bending process, making it impossible to accurately control the bending angle, thereby affecting the quality of the finished product and increasing the error rate. The utility model proposes a multi-angle pipe bender to solve the above problem.

[0033] The utility model provides the following preferred embodiments

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a multi-angle pipe bender comprises:

[0035] A frame 100 and a forming block 200 disposed on the frame 100, wherein a forming groove 210 for accommodating a pipe is provided on a side wall of the forming block 200;

[0036] A holding assembly 300 located at one side of the forming block 200 and holding the pipe against the forming groove 210;

[0037] A driving member 500, which is disposed on the pressing assembly 300 and is used to drive the pressing assembly 300 pressed against the pipe to move along the path of the forming groove 210, so that the pipe presents an outer contour consistent with the path of the forming groove 210;

[0038] The pipe bender effectively wraps and holds the pipe through the built-in profile of the forming groove 210 and the pressing component 300, ensuring that the pipe is in a fixed position and angle during the forming process, avoiding displacement, and improving the stability and accuracy of the bending process. While the pressing component 300 has a limiting effect, it cooperates with the linkage of the driving member 500 to move along the path of the forming groove 210 to deform the pipe, ensuring that the pipe is accurately bent and presents the expected shape and profile, and effectively realizing the deformation processing of the pipe.

[0039] In summary, through the combined application of the forming groove 210, the holding assembly 300 and the driving member 500, the pipe is effectively limited to ensure that the pipe will not move during the bending process, thereby achieving accurate bending processing. By effectively limiting the position and controlling the deformation of the pipe, the movement of the pipe can be reduced, thereby greatly reducing the product failure rate and improving product quality and work efficiency.

[0040] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the forming groove 210 is composed of three sections of straight groove 1 211, rounded groove 212, and straight groove 213 connected in sequence, wherein the straight groove 1 211 is opened on one side of the forming block 200, the straight groove 213 is opened on the other side of the forming block 200, and the side wall of the straight groove 213 is adjacent to the side wall of the straight groove 1 211, and the rounded groove 212 is opened at the angle formed by the straight groove 1 211 and the straight groove 213, so that the path formed by the three sections of the forming groove 210 is in an arc shape, and the notch shape of the forming groove 210 is set to be semicircular. The notch of the forming groove 210 is semicircular, which can fit more closely with the surface of the pipe, effectively reduce the gap and friction, help to protect the appearance and surface quality of the pipe, and avoid damage to the pipe during the deformation process. The better fit reduces the deviation and instability of the pipe during deformation, and can provide better adaptability, so as to achieve a more accurate, efficient and reliable pipe deformation processing process.

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the forming block 200 is provided with a baffle 400 on one side of the forming groove 210, and a avoidance groove 401 is opened on the side of the baffle 400 facing the forming groove 210, and the avoidance groove 401 is distributed in a mirror-symmetrical manner with the forming groove 210. The baffle 400 is used to limit the end of the pipe to prevent the non-stressed end of the pipe from warping, causing the pipe to be unable to deform and bend, further improving the deformation processing process of the pipe, and the mirror-symmetrical layout of the forming groove 210 and the avoidance groove 401 makes the baffle 400 bear a balanced force when blocking the pipe, which is more fitted, avoiding the formation of a gap between the pipe and the avoidance groove 401, resulting in a slight warping of the non-stressed end of the pipe.

[0042] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the driving member 500 includes a driving member 510 that is driven by displacement in the axial direction of the straight groove 211 and a driving member 520 that is driven by displacement in the radial direction of the straight groove 211, and the driving directions of the driving member 510 and the driving member 520 are different. The driving member 510 includes a handle 511, a rocker 512, a support 513, a screw rod 514, a nut 515, a connecting plate 518, a slide rail 516, and a slider 517. The support 513 is fixed on the frame 100, and the two ends of the screw rod 514 are rotatably connected to the support 513 through a rotating shaft. The rocker 512 is fixed to one end of the screw rod 514, the handle 511 is sleeved on one end of the rocker 512, and the nut 515 is connected to the support 516 through a rotating shaft. The thread is screwed on the outer side of the screw rod 514, one side of the connecting plate 518 is fixed on the nut 515, and the other side of the connecting plate 518 is fixed on the slider 517, the slide rail 516 is fixed on the top of the support 513, and the slider 517 slides on the slide rail 516. The second drive 520 includes a cylinder, and the pressing assembly 300 includes a roller 301, a support rod 302, and a cross arm 303. One end of the cross arm 303 is rotatably connected to the connecting plate 518 through a rotating shaft, and the other end of the cross arm 303 is rotatably connected to the driving end of the cylinder through a rotating shaft. The support rod 302 is fixed on the side wall of the cross arm 303 close to the cylinder, and the roller 301 is rotatably connected to the support arm through a rotating shaft;

[0043] First, insert the pipe between the forming groove 210 and the avoidance groove 401, so that it is located in the straight groove 211, and one end is located between the forming groove 210 and the avoidance groove 401. Then, the cylinder moves along the radial direction of the straight groove 211, driving the cross arm 303 to rotate toward the pipe with the connecting end of the connecting plate 518 and the cross arm 303 as the rotation axis. The cantilever drives the roller 301 to rotate toward the pipe through the support rod 302, so that the roller 301 contacts and abuts against the pipe, and the pipe is limited and fixed;

[0044] At the same time, the operator holds the handle 511 and makes the handle 511 perform circular motion with the screw 514 as the rotation axis. The handle 511 drives the screw 514 to rotate through the rocker 512, and the nut 515 moves along the screw 514. The nut 515 drives the connecting plate 518 and the slider 517 to slide on the slide rail 516. The connecting plate 518 drives the cross arm 303, the support rod 302 and the roller 301 to move axially along the straight groove 211, so that the roller 301 is pressed on the pipe and rolls along the axial direction of the straight groove 211. In addition, under the support of the cylinder drive, the roller 301 draws a curved trajectory during the rolling process on the pipe, which coincides with the path of the fillet groove 212, thereby realizing the arc bending processing process of the pipe.

[0045] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a limiting groove 600 is provided on the outer side of the roller 301 along the circumference of the roller 301. The groove shape of the limiting groove 600 is set to be semicircular and has the same radial size as the forming groove 210, thereby enhancing the limiting control of the roller 301. At the same time, through the semicircular groove design and the consistency with the forming groove 210, the accuracy of the processing process and the safety of the pipe are effectively guaranteed. Due to the design of the limiting groove 600 on the outer side of the roller 301, the movement range of the roller 301 is more effectively limited during the processing, and it moves according to a specific trajectory, thereby improving the stability and accuracy of the pipe processing. The limiting groove 600 adopts a semicircular design and has the same size as the forming groove 210, which can better fit the surface of the pipe and reduce friction and the risk of damage to the pipe.

[0046] The specific working process of the utility model is as follows:

[0047] (1) Place the pipe with a bend

[0048] First, the pipe is inserted between the forming groove 210 and the avoidance groove 401 so that it is located in the straight groove 211 and one end thereof is located between the forming groove 210 and the avoidance groove 401 .

[0049] (2) Limit the position of the pipe

[0050] Next, the cylinder moves along the radial direction of the straight groove 211, driving the cross arm 303 to rotate toward the pipe with the connecting plate 518 and the connecting end of the cross arm 303 as the rotation axis. The cantilever drives the roller 301 to rotate toward the pipe through the support rod 302, so that the roller 301 contacts and abuts against the pipe, thereby limiting and fixing the pipe.

[0051] (3) Bending the pipe

[0052] At the same time, the operator holds the handle 511 and makes the handle 511 perform circular motion with the screw 514 as the rotation axis. The handle 511 drives the screw 514 to rotate through the rocker 512, and the nut 515 moves along the screw 514. The nut 515 drives the connecting plate 518 and the slider 517 to slide on the slide rail 516. The connecting plate 518 drives the cross arm 303, the support rod 302 and the roller 301 to move axially along the straight groove 211, so that the roller 301 is pressed on the pipe and rolls along the axial direction of the straight groove 211. In addition, under the support of the cylinder drive, the roller 301 draws an arc-shaped trajectory during the rolling process on the pipe, which coincides with the path of the fillet groove 212, so that the roller 301 is against the other end of the pipe and the other end of the pipe is pressed into the straight groove 213, thereby realizing the arc bending processing process of the pipe.
