DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Please refer to Figure 1-5 ;

[0024] The device of the utility model has the functions of bending and punching at the same time, and is intended to complete the punching step in one bending process to improve production efficiency; it specifically comprises a bending seat 11, a punching device 2 is provided on one side of the bending seat 11, and the punching device 2 is installed on a floating clamping device 3, that is, the punching device 2 can move together with the floating clamping device 3, and the floating clamping device 3 and the bending seat 11 have a height difference, and the floating clamping device 3 rotates synchronously with the bending seat 11, and is located between the two to form a metal pipe clamping position;

[0025] In the initial state, the floating clamping device 3 and the bending seat 11 are in a separated state, that is, the clamping position 1 is in an open state. At this time, the metal pipe is pushed to a position close to the bending seat 11 by an external feeding mechanism, and then the floating clamping device 3 approaches the bending seat 11 and combines with it to form a clamping position 1 to clamp the metal pipe. Then the bending seat 11 and the floating clamping device 3 rotate synchronously, so that the clamping position 1 rotates with the bending seat 11 as the midpoint, thereby achieving the purpose of bending the metal pipe. It should be noted that each bending process only processes part of the metal pipe, so the part of the metal pipe outside the clamping position 1 will have a tendency to move in the opposite direction of the bending. Therefore, the position of the metal pipe needs to be fixed to achieve bending. Therefore, a resistance component should be provided on the equipment to resist the outside of the metal pipe, such as a baffle, a resistance member, etc., which is a commonly used technical means and will not be described in detail this time.

[0026] Preferably, the floating clamping device 3 and the bending seat 11 are connected via the same driving device 5 .

[0027] After completing a bending operation, the floating clamping device 3 tilts downward to realize the material withdrawal action, and the bending seat 11 rotates in the opposite direction to reset. Then the external feeding mechanism pushes the metal pipe forward here, and then the floating clamping device 3 moves again in combination with the bending seat 11 to clamp the metal pipe. At this time, the metal pipe has been fixed. Finally, the punching device 2 can horizontally pass through the floating clamping device 3 to enter the clamping position 1, and pass through the metal pipe to realize the punching operation. Furthermore, the formed clamping position 1 is adapted to the shape of the metal pipe, so the metal pipe can be prevented from being deformed during the punching process. Moreover, under the operation of the same product, the distance the metal pipe is pushed each time is the same, which can be set through the program of the equipment. Therefore, the position of each punching can be the same, thereby improving the punching accuracy. Moreover, there is no need to transport the metal pipe, that is, there is no need to position it, thereby reducing the process flow and improving production efficiency.

[0028] It should be noted that the metal pipe will be pulled out a certain distance during the bending process, so during the bending operation, the external feeding mechanism should loosen the metal pipe and then clamp it after the bending is completed.

[0029] Based on the implementation method, the metal tube can be pushed forward in sections multiple times through an external feeding mechanism. After the punching is completed, the bending operation is performed simultaneously, or the clamping position is opened again, the metal core tube is pushed forward for a section through the external feeding mechanism, and then the bending operation is performed.

[0030] Furthermore, the punching described in this embodiment can be either drilling or punching, again without limitation.

[0031] One of the embodiments of the floating clamping device 3 of the utility model specifically includes a mounting seat 31. Based on the above embodiment, the floating clamping device 3 and the bending seat 11 rotate synchronously, so the mounting seat 31 and the bending seat 11 use the same driving device 5, and a driving component 32 is installed on the mounting seat 31, and the driving component 32 is connected to a movable seat 33. A pressing head 34 is installed on the movable seat 33, and a groove 35 is provided on the pressing head 34. Of course, the other half of the groove 4 12 corresponding to the groove 35 is provided on the bending seat 11, and the groove 35 and the groove 4 12 are combined to form a clamping position 1; preferably, a guide groove 13 is provided at a position close to the groove 4 12 on the bending seat 11, and the pressing head 34 can only be combined with the groove 4 12 when it enters the guide groove 13. The setting of the guide groove 13 can ensure that the groove 35 and the groove 4 12 are combined in place, and the metal pipe is protected at the same time.

[0032] In this embodiment, the mounting seat is coaxially arranged with the bending seat 11, and all components are mounted on the mounting seat, that is, the overall rotation is realized. Secondly, the movable seat 33 is driven to move obliquely by the driving component 132, so that the floating purpose can be achieved, which is used to form an empty space and facilitate back bending. In addition, in addition to providing power, the driving component 132 also has the function of supporting the movable seat. During operation, the driving component 132 is used to push the movable seat to move obliquely upward, so that the pressure head 134 is tightly attached to the bending seat 11 to form a clamping position 1, and the metal pipe is clamped and fixed at the same time. Then, the driving device 5 is used to drive the bending seat 11 and the mounting seat to rotate synchronously to complete the bending. After completion, the driving component 132 is reset, so that the movable seat is tilted downward, that is, the pressure head 134 is separated from the bending seat 11 to achieve back bending, so that the bent part of the metal pipe is separated from the bending seat 11 and the pressure head 134, and finally, the bending seat 11 and the mounting seat are reset under the drive of the driving device 5.

[0033] The driving assembly 32 is further described, which specifically includes a cylinder 321. The output end of the cylinder 321 is rotatably connected to an "L"-shaped transmission plate 322. The cylinder 321 and the transmission plate 322 in this embodiment are both inclined, and the output end of the cylinder 321 is connected to one end of the lower part of the "L", and the other end of the lower part is connected to the transmission plate 324, and the upper end is connected to the transmission plate 2 323. At the same time, the end of the upper part is rotatably connected to the mounting seat, and the transmission plate 2 323 and the transmission plate 3 324 are respectively driven to move through the transmission plate 1 322, and the transmission plate 2 323 and the transmission plate 3 324 are spaced apart, so as to form two support points for the movable seat. In addition, the other end of the transmission plate 2 is rotatably connected to the mounting seat through the transmission plate 1 322, and the position where the transmission plate 3 324 is rotatably connected to the movable seat is also rotatably connected to the transmission plate 4 325, and the other end of the transmission plate 4 325 is rotatably connected to the mounting seat 31;

[0034] The cylinder 1 321 drives the transmission plate 1 322 to move, and the transmission plate 2 323, the transmission plate 3 324 and the transmission plate 4 325 are linked in sequence to realize the tilting movement of the movable seat.

[0035] In the embodiment of the utility model, the punching device 2 includes a driving component 3 21 installed on a movable seat 1 33, and a hole forming part 22 is installed at the output end of the driving component 3 21, wherein the driving component 3 21 is placed horizontally, and when the punching method is drilling, the driving component 3 21 is a combination of a motor and a cylinder, wherein the output end of the motor is connected to the hole forming part 22, and the output end of the cylinder is connected to the end of the motor, and a sliding pair is provided between the motor and the movable seat, and the motor is pushed to move by the cylinder, so that the hole forming part 22 can penetrate the pressure head 1 34 and extend into the groove 1 35;

[0036] When the punching method is punching, the driving component three 21 is an electric cylinder, which drives the hole-forming part 22 to penetrate the pressure head 34 and extend into the groove 35. No matter which method is adopted, the hole-forming part 22 moves horizontally left and right. Such a setting can save space for the equipment and avoid interference with bending.

[0037] In the embodiment of the utility model, since the metal pipe will be driven forward during the bending process, if its position is not restricted, it will affect the bending effect. Therefore, an auxiliary device 4 is installed on one side of the floating clamping device 3 to limit the position of the metal pipe. More specifically, the auxiliary device 4 includes a mounting seat 41, a driving component 42 is installed on the mounting seat 41, and a movable seat 43 is installed at the output end of the driving component 42. The movable seat 43 is slidably connected to the mounting seat 41. The specific structure of the driving component 42 can refer to the driving component 32. In the embodiment, the movable seat 43 is driven to float by the driving component 42, and the movable seat 43 is installed with a cylinder 44, and the extension direction of the cylinder 44 is consistent with the feeding direction of the metal pipe. The output end of the cylinder 44 is connected with a movable plate 45, and one side of the movable plate 45 is connected to the movable seat 43 through a sliding pair, and a pressure head 46 is provided on the other side, and a groove 47 is provided on the pressure head 46. A pressure head 48 is provided on one side of the bending seat 11, and a groove 49 is provided on the pressure head 48, which forms a clamping position 2 with the groove 47 structure;

[0038] In the initial state, groove three 49 is aligned with groove four 12 on the bending seat 11. When the metal pipe needs to be clamped, the floating clamping device 3 and the auxiliary device 4 move toward the bending seat 11 and the pressure head three 48 respectively, and the formed clamping position one and clamping position two clamp the metal pipe. At this time, clamping position one and clamping position two are in the same straight line. When bending the pipe, the position of clamping position one changes, and the metal pipe will be pulled a certain distance. At the same time, cylinder two 44 will drive the movable plate 45 to move in the direction where the metal pipe is pulled, and groove two 47 keeps in contact with the metal pipe, which can ensure that the metal pipe remains in a straight line from the bend to clamping position two and will not be bent, thereby ensuring the molding effect of the final product.

[0039] It should be noted that the second groove 47 is relatively long and keeps in contact with the third groove 49 during the movement, that is, keeps the metal pipe in a clamped state.

[0040] One embodiment of the driving device 5 of the present invention specifically includes a central rotating shaft 51, which passes through the bending seat 11, the mounting seat 1 31 and the gear 52 respectively. Of course, all three are fixed to the rotating shaft position, and the rack 53 is driven to move linearly through the driving component 4 54, thereby driving the gear 52 to rotate, and the gear 52 drives the rotating shaft to rotate, that is, the bending seat 11 and the mounting seat are finally rotated synchronously.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
