[0034] Application Overview
[0035] The existing manual material placement is greatly affected by the personnel's state. Every time the oil pipe is placed in the pipe bending machine, there is a slight placement deviation in the position of the oil pipe. Especially after the processing personnel repeat the simple action of loading and unloading for a long time, their attention is easily distracted, and it is further difficult to ensure that the oil pipe is placed in the designated position of the pipe bending machine, affecting the bending quality.
[0036] Based on the above technical problems, the present application proposes an automatic short tube bending equipment, wherein the automatic short tube bending equipment has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the automatic short tube bending equipment provided by the present application is easy to produce and low-cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
[0037] Schematic short pipe automatic bending equipment,
[0038] refer to Figures 1 to 6 According to a preferred embodiment of the utility model, an automatic short tube bending device is used for bending short tubes. The automatic short tube bending device includes a machine base 10, a tube bending machine 20, a material preparation module 30, a feeding module 40 and a unloading module 50.
[0039] Specifically, Figure 1As shown, the pipe bender 20 has a plurality of clamping holes 201, and the clamping holes 201 are used to clamp the short tube. It should be noted that before the pipe bender 20 bends the short tube, the short tube is a straight tube, and the material of the short tube is metal, and the short tube is hollow.
[0040] In addition, if Figure 1 As shown, the material preparation module 30 includes a plurality of protrusions 3011 arranged in an array, each of the protrusions 3011 is disposed on the machine base 10, and each of the protrusions 3011 is sleeved with a short tube. When the short tube is sleeved on the protrusion 3011, the short tube is arranged vertically.
[0041] In addition, if Figure 1 As shown, the feeding module 40 includes an internal expansion device 401 and a frame assembly 402, the frame assembly 402 is connected to the machine base 10 and is located above the material preparation module 30, the internal expansion device 401 is slidably arranged on the frame assembly 402, and the internal expansion device 401 reciprocates between the material preparation module 30 and the pipe bending machine 20, the internal expansion device 401 is liftably arranged on the frame assembly 402 and approaches or moves away from the short tube sleeved on the protrusion 3011, the internal expansion device 401 is also flipably arranged on the frame assembly 402, when the internal expansion device 401 is flipped at a predetermined angle, the internal expansion device 401 is opposite to the protrusion 3011 or the clamping hole 201 of the pipe bending machine 20, the internal expansion device 401 is also slidably arranged on the frame assembly 402 forwards and backwards and approaches or moves away from the clamping hole 201.
[0042] In addition, if Figure 1 As shown, the unloading module 50 is located at one end of the pipe bending machine 20 where the clamping hole 201 is provided.
[0043] It should be noted that the internal expansion device 401 includes a plurality of three-annular array clamps (not marked in the figure) and a three-jaw chuck (not marked in the figure), and each jaw on the three-jaw chuck is fixedly connected to a clamp. When the three jaws move toward or away from each other, the three clamps also move toward or away from each other. Since the short tube is hollow, when the three clamps are extended into the short tube, the three clamps move synchronously away from each other, and at a certain moment each clamp is pressed against the inner hole wall of the short tube to clamp the short tube. During processing, assuming that the internal expansion device 401 is located above the short tube, by moving the internal expansion device 401 downward by a predetermined distance, the internal expansion device 401 clamps the short tube sleeved on the protrusion 3011 directly below, and then by moving the internal expansion device 401 upward by a predetermined distance, the end of the short tube away from the internal expansion device 401 is separated from the protrusion 3011; by sliding the internal expansion device 401 toward the tube bender 20, at a certain moment, the short tube is in contact with the tube bender 20. The clamping holes 201 on the pipe are located on the same plane; by turning the internal expansion device 401 by 90°, the short tube originally arranged vertically will also turn by 90°, and the short tube will be opposite to the clamping hole 201; by moving the internal expansion device 401 toward the clamping hole 201 by a predetermined distance, one end of the short tube will extend into the clamping hole 201, so that the pipe bender 20 can bend the short tube; after the short tube is bent, the short tube will be separated from the pipe bender 20 and fall onto the unloading module 50. Obviously, compared with the prior art that requires manual loading and unloading, the embodiment of the present application realizes mechanical loading and unloading by setting the preparation module 30, the feeding module 40 and the unloading module 50, and the position of the short tube when feeding it into the pipe bender 20 is more stable and the continuity is also higher.
[0044] It should also be noted that the action of sleeve-mounting the short tube on the protrusion 3011 is achieved manually. To avoid the manual worker accidentally touching the internal expansion device 401 and being injured during material discharge, Figure 2 As shown, the machine base 10 has a material preparation portion 101 and a material clamping portion 102, and the material clamping portion 102 is located directly below the internal expansion device 401. The material preparation module 30 also includes a plurality of trays 301, each of which is provided with a plurality of protrusions 3011. Each of the trays 301 is slidably disposed on the machine base 10, and the tray 301 slides back and forth between the material preparation portion 101 and the material clamping portion 102.
[0045] In addition, if Figure 2As shown, the machine base 10 further includes a protective member 103, which is disposed between the material preparation portion 101 and the material clamping portion 102. The protective member 103 is fixedly connected to the machine base 10, and its fixed connection method includes but is not limited to welding or bolt connection.
[0046] It should be noted that when the short tube is manually sleeved on the protrusion 3011, the tray 301 is located in the material preparation section 101. Since the protective member 103 isolates the material preparation section 101 and the clamping section 102, the internal expansion device 401 will not be accidentally touched when the short tube is manually sleeved on the protrusion 3011. When the tray 301 moves to the clamping section 102, the internal expansion device 401 moves downward to expand and take out the short tube on the protrusion 3011, thereby realizing mechanization of loading.
[0047] Furthermore, in order to realize that the internal expansion device 401 is slidably, liftably, forwardly and backwardly and flippably arranged on the frame assembly 402, as shown in FIG. Figure 3 and Figure 4 As shown, the frame assembly 402 also includes a frame bucket 4021, a first linear module 4022, a first seat body 4023, a second linear module 4024, a second seat body 4025, a third linear module 4026, a flip drive device 4027 and a third seat body 4028. The frame bucket 4021 is fixedly connected to the machine base 10, and its fixed connection method includes but is not limited to bolt connection. The first linear module 4022 is connected to the frame bucket 4021, and the slider of the first linear module 4022 slides back and forth in the length direction of the frame bucket 4021. The second linear module 4024 is fixedly connected to the slider of the first linear module 4022 by bolt connection, and the first seat body 4023 is connected to The slider of the second linear module 4024 is fixedly connected, and the slider of the second linear module 4024 slides back and forth in the width direction of the bucket 4021, the second seat body 4025 is located at the end of the first seat body 4023 away from the bucket 4021 and is arranged vertically with the first seat body 4023, and the second seat body 4025 is connected to the first seat body 4023 and follows the movement, the third linear module 4026 is installed on the second seat body 4025, the flip drive device 4027 is installed on the slider of the third linear module 4026, the third seat body 4028 is rotatably connected to the flip drive device 4027, and the internal expansion device 401 is fixedly installed on the third seat body 4028.
[0048] It should be noted that when the first linear module 4022 is actuated, the internal expansion device 401 slides in the length direction of the bucket 4021; when the second linear module 4024 is actuated, the internal expansion device 401 slides in the width direction of the bucket 4021; when the third linear module 4026 is actuated, the internal expansion device 401 slides up and down in the height direction of the bucket 4021; when the flipping drive device 4027 is actuated, the internal expansion device 401 flips at a predetermined angle. In this embodiment of the present application, when the flipping drive device 4027 is actuated, the internal expansion device 401 flips 90°.
[0049] Specifically, to achieve the flipping of the internal expansion device 401, as shown in FIG. Figure 4 As shown, the third seat body 4028 is rotationally connected to the flip drive device 4027 in the form of a pin, and the push rod of the flip drive device 4027 is in contact with the wall of the third seat body 4028. In addition, the flip drive device 4027 has a supporting portion 40271 on the side away from its push rod. When the push rod of the flip drive device 4027 is extended, the third seat body 4028 is thrust and rotates in the direction of the supporting portion 40271, and at a certain moment, the third seat body 4028 is in contact with the supporting portion 40271.
[0050] Furthermore, if Figure 1 , Figure 5 and Figure 6 As shown, the pipe bending machine 20 includes a base 202, a rotary drive device 203, a rotating seat 204, a first clamping assembly 205, a second clamping assembly 206 and a pushing member 207. The rotary drive device 203 is installed on the base 202. The rotary drive device 203 is further implemented as a rotary motor. The rotating seat 204 is connected to the rotating shaft of the rotary drive device 203. The first clamping assembly 205 is fixedly installed on the rotating seat 204 and rotates with it. The second clamping assembly 206 is fixed on the base 202. The pushing member 207 is slidably arranged on the base 202 and approaches or moves away from the second clamping assembly 206.
[0051] It should be noted that, after the short tube is extended into the clamping hole 201, the short tube is clamped by the first clamping assembly 205 and the second clamping assembly 206, and the rotating shaft of the rotating drive device 203 rotates and drives the rotating seat 204 to rotate, so that the first clamping assembly 205 follows the rotation by a predetermined angle. Since the short tube is clamped by the second clamping assembly 206 at the same time, the part of the short tube clamped by the first clamping assembly 205 is bent by a predetermined angle relative to the part clamped by the second clamping assembly 206, so as to achieve the bending of the short tube, and the short tube is pushed outward by a predetermined distance by the pushing member 207. After repeating the above bending work several times, the bent short tube is completely pushed out of the clamping hole 201 by the pushing member 207, and is made to fall into the unloading module 50, so as to achieve the dropping of the short tube.
[0052] More specifically, in order to achieve the first clamping assembly 205 clamping the short tube, as Figure 5 and Figure 6 As shown, the first clamping assembly 205 includes a first half fastener 2051 and a second half fastener 2052, the first half fastener 2051 is fixedly mounted on the rotating seat 204, the second half fastener 2052 is slidably disposed on the rotating seat 204 and approaches or moves away from the first half fastener 2051, and the first half fastener 2051 and the second half fastener 2052 have a plurality of first semicircular holes (not marked in the figure) at opposite ends. When the second half fastener 2052 abuts against the first half fastener 2051, the first semicircular holes on the first half fastener 2051 and the second half fastener 2052 are spliced to form the clamping hole 201.
[0053] More specifically, in order to achieve the second half fastener 2052 being close to or away from the first half fastener 2051, as Figure 6As shown, the first clamping assembly 205 also includes a linear drive device 2053, a first connecting rod 2054 and a second connecting rod 2055. The linear drive device 2053 is rotatably mounted on the rotating seat 204. One end of the first connecting rod 2054 is rotatably connected to the second half fastener 2052. The other end of the first connecting rod 2054 is hinged to the push rod of the linear drive device 2053 and one end of the second connecting rod 2055 at the same time. One end of the second connecting rod 2055 that is away from the push rod of the linear drive device 2053 is rotatably connected to the rotating seat 204, and the first connecting rod 2054 and the second connecting rod 2055 form a V shape, and the push rod of the linear drive device 2053 is located at the bottom of the V shape. When the push rod of the linear drive device 2053 moves, the angle between the first connecting rod 2054 and the second connecting rod 2055 increases or decreases, and the second half fastener 2052 is moved closer to or away from the first half fastener 2051.
[0054] It should be noted that when the short tube extends into the clamping hole 201, the linear drive device 2053 is not working. At this time, the second half fastener 2052 is spaced a predetermined distance from the first half fastener 2051. When the short tube penetrates into the clamping hole 201, the linear drive device 2053 is activated, and the second half fastener 2052 moves a predetermined distance toward the first half fastener 2051 to achieve clamping of the short tube.
[0055] Similarly, in order to achieve the second clamping assembly 206 clamping the short tube, Figure 5 As shown, the second clamping assembly 206 includes a third half fastener and a fourth half fastener (not marked in the figure), and the fourth half fastener is driven by an electric push rod to slide on the base 202. The first half fastener 2051 and the second half fastener 2052 have a plurality of second semicircular holes (not marked in the figure) at the opposite ends, and the second semicircular holes correspond to the first semicircular holes one by one and have the same aperture diameter. When the fourth half fastener abuts against the third half fastener, the second semicircular holes on the fourth half fastener and the third half fastener are spliced to form the clamping hole 201.
[0056] Furthermore, in order to achieve the pushing member 207 to move closer to or farther from the clamping hole 201, as Figure 1 As shown, the pipe bending machine 20 further includes a fourth linear module 208 , which is fixedly mounted on the base 202 , and the pushing member 207 is connected to a slider of the fourth linear module 208 .
[0057] Furthermore, if Figure 1As shown, the unloading module 50 includes a conveyor belt 501, and the conveyor belt 501 is located between the machine base 10 and the pipe bender 20. The machine base 10, the conveyor belt 501 and the pipe bender 20 are in an L shape as a whole.
[0058] In summary, the short tube automatic bending equipment based on the embodiment of the present application is explained, which provides the short tube automatic bending equipment with advantages such as mechanical loading and unloading and better stability.
