Abstract
Description
Technical Field
[0001] This application relates to the field of metal bending technology, and more particularly to a metal bending device. Background Technology
[0002] Current metal bending processes, especially for bending metal pipes, typically involve direct pressing with a fixture. However, when bending a metal pipe into a closed shape, where the two ends of the pipe approach each other and form an encirclement, the fixture becomes surrounded by the pipe and is difficult to remove. Utility Model Content
[0003] To solve the above problems, this technical solution provides a metal bending device.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A metal bending device, comprising
[0006] A bending table is provided with hydraulic cylinders for supporting limiters at both ends of the metal part, a buffer, and an insert mechanism located between the two limiters.
[0007] The insert mechanism includes a first insert disposed on the output end of the hydraulic cylinder, a second insert and a third insert that cooperate with the first insert, and a fourth insert that cooperates with the buffer to clamp the metal part;
[0008] When the output end of the hydraulic cylinder extends, the first insert presses against the second insert and the third insert from both sides, so that the fourth insert is embedded between the second insert and the third insert. The insert mechanism presses the metal part against the limiter so that the metal part bends.
[0009] When the output end of the hydraulic cylinder retracts, the fourth insert and the first insert retract sequentially from the second insert and the third insert, and the second insert and the third insert move closer together.
[0010] In the metal bending device described above, a first slide rail is provided between the third insert and the bending table, and the sliding direction of the first slide rail is consistent with the extension direction of the output end of the hydraulic cylinder.
[0011] In the metal bending device described above, a tension spring is provided between the second insert and the third insert to give the second insert a tendency to move closer to the third insert.
[0012] In the metal bending device described above, the second insert and the third insert are respectively provided with a slider and a groove, the slider and the groove cooperating to allow the second insert to slide laterally relative to the third insert.
[0013] In the metal bending device described above, a second slide rail is provided between the fourth insert and the bending table, and the sliding direction of the second slide rail is consistent with the extension direction of the output end of the hydraulic cylinder.
[0014] As described above, in a metal bending device, the buffer includes a buffer seat, a buffer rod that slides in cooperation with the buffer seat, a buffer block disposed on the buffer rod, and a buffer spring disposed between the buffer block and the buffer seat.
[0015] In the metal bending device described above, the third insert is provided with a limiting groove, and the second insert is provided with a limiting block. The limiting groove and the limiting block cooperate to make the second insert and the third insert move synchronously in a direction away from or close to the buffer.
[0016] In the metal bending device described above, the first insert has a first inclined surface, the second insert has a second inclined surface, and the first inclined surface pushes against the second inclined surface to move the second insert away from the third insert.
[0017] In the metal bending device described above, a cavity is provided between the second insert and the third insert for the first insert to be inserted.
[0018] The beneficial effects of this application are:
[0019] This invention provides a metal bending device. When bending a metal pipe, it is placed on a limiter, and then the output end of a hydraulic cylinder extends. The first insert presses against the second and third inserts from both sides, causing them to separate as the first insert moves, allowing a fourth insert to embed between the second and third inserts. At this time, the insert mechanism presses the metal part against the limiter, causing the metal part to bend. When the output end of the hydraulic cylinder retracts, the fourth insert and the first insert retract sequentially from the second and third inserts, and the second and third inserts move closer together. At this time, the distance between the second and third inserts decreases, making it easier for the metal pipe to disengage from the insert mechanism. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] A metal bending device, comprising
[0025] A bending table 1 is provided with a hydraulic cylinder 2 for supporting the limiters 3 at both ends of the metal part 7, a buffer 4, and an insert mechanism 5 located between the two limiters 3.
[0026] The insert mechanism 5 includes a first insert 51 disposed on the output end of the hydraulic cylinder 2, a second insert 52 and a third insert 53 that cooperate with the first insert 51, and a fourth insert 54 that cooperates with the buffer 4 to clamp the metal part.
[0027] When the output end of the hydraulic cylinder 2 extends, the first insert 51 presses against the second insert 52 and the third insert 53 on both sides, so that the fourth insert 54 is embedded between the second insert 52 and the third insert 53. The insert mechanism 5 presses the metal part against the limiter 3 so that the metal part bends.
[0028] When the output end of the hydraulic cylinder 2 retracts, the fourth insert 54 and the first insert 51 exit from the second insert 52 and the third insert 53 in sequence, and the second insert 52 and the third insert 53 move closer together.
[0029] This invention provides a metal bending device. When bending a metal pipe, it is placed on a limiter, and then the output end of a hydraulic cylinder extends. The first insert presses against the second and third inserts from both sides, causing them to separate as the first insert moves, allowing a fourth insert to embed between the second and third inserts. At this time, the insert mechanism presses the metal part against the limiter, causing the metal part to bend. When the output end of the hydraulic cylinder retracts, the fourth insert and the first insert retract sequentially from the second and third inserts, and the second and third inserts move closer together. At this time, the distance between the second and third inserts decreases, making it easier for the metal pipe to disengage from the insert mechanism.
[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, a first slide rail 55 is provided between the third insert 53 and the bending table 1, and the sliding direction of the first slide rail 55 is consistent with the extension direction of the output end of the hydraulic cylinder 2. This improves the stability of the movement of the third insert.
[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, a tension spring 56 is provided between the second insert 52 and the third insert 53, so that the second insert 52 has a tendency to move closer to the third insert 53. The first insert has a U-shaped groove inside, which makes way for the tension spring.
[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the second insert 52 and the third insert 53 are respectively provided with a slider 57 and a groove 58, the slider 57 and the groove 58 cooperating to allow the second insert 52 to slide laterally relative to the third insert 53. This improves the stability of the movement of the second insert relative to the third insert.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, a second slide rail 59 is provided between the fourth insert 54 and the bending table 1, and the sliding direction of the second slide rail 59 is consistent with the extension direction of the output end of the hydraulic cylinder 2. This improves the stability of the movement of the fourth insert.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the buffer 4 includes a buffer seat 41, a buffer rod 42 that slides in cooperation with the buffer seat 41, a buffer block 43 disposed on the buffer rod 42, and a buffer spring 44 disposed between the buffer block 43 and the buffer seat 41. The buffer block and the fourth insert together clamp the metal tube, keeping the clamping section straight and preventing bending.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the third insert 53 is provided with a limiting groove 531, and the second insert 52 is provided with a limiting block 521. The limiting groove 531 cooperates with the limiting block 521 to allow the second insert 52 and the third insert 53 to move synchronously in a direction away from or towards the buffer 4. This improves the stability of the movement of the second insert relative to the third insert.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the first insert 51 is provided with a first inclined surface 511, and the second insert 52 is provided with a second inclined surface 522. The first inclined surface 511 pushes against the second inclined surface 522, causing the second insert 52 to move away from the third insert 53. The distance between the second insert and the third insert is increased by pushing against the inclined surface.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, a cavity 6 is provided between the second insert 52 and the third insert 53 for the first insert 51 to be inserted.
