An aluminum alloy bending device

Abstract

This utility model discloses an aluminum alloy bending device, including a bending ring and an upper wrench rotatably connected thereto. A ratchet is rotatably connected to the outer wall of the bending ring, a baffle is fixedly connected to the outer wall of the ratchet, a pawl is rotatably connected to the outer wall of the bending ring, and a spring is fixedly connected to the outer wall of the bending ring. A limit plate is fixedly connected to the outer wall of the upper wrench. The ratchet can rotate counterclockwise, allowing the baffle on the ratchet to be adjusted to the desired angle. When the user operates the upper wrench to bend the aluminum alloy tube, they can simply apply force. When the predetermined angle is reached, the limit plate is blocked by the baffle, preventing the tube from bending too much. The limit angle can be determined according to the scale display while the ratchet is rotating, thus facilitating bending for the user.

Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy bending technology, and specifically relates to an aluminum alloy bending device. Background Technology

[0002] Pipes are widely used in various industries, especially small-diameter metal pipes, which are frequently seen in daily life. If you bend pipes directly by hand, not only will the pipe's cross-section change, but it is also easy to break the pipe. A pipe bender is a special tool for bending pipes. Place the pipe into the guide groove of the fixed wheel, guide the pipe with the guide groove of the movable rod, and hold the handle of the movable rod to rotate it smoothly to bend the pipe into the desired specific shape.

[0003] The pipe bender described in patent CN102327937A has multiple grooves of different sizes and multiple guide grooves corresponding to these grooves. Therefore, it can be applied to bend pipes of different diameters, avoiding the disadvantage of needing multiple pipe benders due to different pipe sizes. It can save costs and improve work efficiency. However, since it is processed manually, it is easy to over-bend due to excessive force when bending. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an aluminum alloy bending device that has the advantage of avoiding over-bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy bending device, comprising a bending ring and an upper wrench rotatably connected thereto, a ratchet rotatably connected to the outer wall of the bending ring, a baffle fixedly connected to the outer wall of the ratchet, a pawl rotatably connected to the outer wall of the bending ring, a spring piece fixedly connected to the outer wall of the bending ring, and a limit plate fixedly connected to the outer wall of the upper wrench.

[0006] The above technical solution can prevent over-bending. The ratchet can rotate counterclockwise, which can adjust the baffle on the ratchet to the required angle. When the user operates the wrench to turn the aluminum alloy tube, he can simply force it. When the predetermined angle is reached, the limit plate will be blocked by the baffle, thus preventing the tube from bending too much.

[0007] Preferably, the outer wall of the bend is fixedly connected to a housing, and the outer wall of the housing is provided with a dial.

[0008] The above technical solution can achieve the effect of displaying scales. When the ratchet rotates, the limit angle can be determined according to the scale display, thus making it convenient for users to bend the ratchet.

[0009] Preferably, the bending ring includes a ring body for bending, and a connecting shaft is fixedly connected to the outer wall of the ring body.

[0010] The above technical solution can achieve the effect of connection. The coupling can provide a rotating pair for the ratchet, thereby allowing the ratchet to rotate.

[0011] Preferably, a connecting column is fixedly connected to the outer wall of the ring, and a clamping plate is fixedly connected to the outer wall of the ring.

[0012] The above technical solution can achieve the installation effect. The connecting post on the ring body can be used to install the pawl, and the clamping plate can be used to install the spring clip.

[0013] Preferably, the ratchet includes a base rotatably connected to a coupling shaft, a protrusion is fixedly connected to the outer wall of the base, and a fixing block is fixedly connected to the outer wall of the protrusion.

[0014] The above technical solution can serve as a connection. The base is used to open gears and rotating grooves, the protrusions can seal the outer shell, and the fixing blocks can serve to fix the connecting baffle.

[0015] Preferably, a base plate is fixedly connected to the outer wall of the bend ring, and a lower handle is fixedly connected to the outer wall of the base plate.

[0016] The above technical solution facilitates operation. The base plate allows for the placement of aluminum alloy pipes, while the lower handle and upper wrench enable shearing and bending of the pipes.

[0017] Preferably, the bend ring is connected to the outer wall of the upper wrench by a hinge, and the outer wall of the upper wrench is tangent to the outer wall of the bend ring.

[0018] The above technical solution can achieve the effect of connection. The hinge between the bend ring and the upper wrench allows for more freedom and makes the operation less rigid. When bending, the outer wall of the upper wrench is tangent to the outer wall of the bend ring, which makes it easier to apply force to the pipe during bending.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The ratchet can rotate counterclockwise, which allows the baffle on the ratchet to be adjusted to the required angle. When the user operates the wrench to turn the aluminum alloy tube, they can simply force it. When the predetermined angle is reached, the limit plate will be blocked by the baffle, thus preventing the tube from bending too much. When the ratchet is rotating, the limit angle can be determined according to the scale display, making it convenient for the user to bend the tube.

[0021] 2. The ratchet can be rotated by the coupling, and the ratchet can be rotated by the connecting column on the ring body. The pawl can be installed by the clamping plate, and the spring can be installed by the clamping plate. The base is used to cut gears and rotating grooves. The protrusion can seal the outer shell, and the fixing block can fix the connecting baffle. Attached Figure Description
