Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

example (b):

as shown in fig. 1-3, a flanging tool includes a tool body 1 and a movable tool bit 2, the movable tool bit 2 is rotatably connected to the tool body 1, when the bottom surface of the movable tool bit 2 is flush with the bottom surface of the tool body 1, one end of the movable tool bit 2, which is far away from the tool body 1, protrudes out of the tool body 1, and the movable tool bit 2 cannot continue to rotate towards the top of the tool body 1.

A through groove 3 is formed in one end, close to the bottom surface, of the cutter body 1, the movable cutter head 2 comprises a bending portion 4 and a connecting portion 5, one end of the connecting portion 5 is connected with the bending portion 4, and the other end of the connecting portion 5 is arranged in the through groove 3 through a fixing pin 6; the one end that the portion of bending 4 is close to connecting portion 5 is equipped with first inclined plane 7, the one end that the portion of bending 4 is close to in cutter main body 1 bottom is equipped with second inclined plane 8, and when the bottom surface of the portion of bending 4 and the bottom surface of cutter main body 1 were leveled the peaceful time, first inclined plane 7 and the laminating of second inclined plane 8.

The working principle is as follows: after the door leaf 12 to be bent arrives, the bending machine is started, the bending machine moves downwards, the movable cutter head 2 is firstly contacted with the door leaf 12 to be bent, and along with the continuous downward movement of the bending machine (the cutter main body 1), the movable cutter head 2 rotates around the axis of the fixed pin 6. When the bottom surface of the cutter body 1 is attached to the door leaf 12 to be bent, the bottom surface of the movable cutter head 2 is also attached to the door leaf 12 to be bent, and at this time, the extending end of the movable cutter head 2, namely, the bending part 4, extends into the bending dead angle of the door leaf 12 to be bent (the bending dead angle is shown in a part a in fig. 3). At the moment, the upward displacement of the movable cutter head 2 is limited due to the action of the first inclined surface 7 and the second inclined surface 8, and then the bending operation can be started; the movable tool bit 2 can extend into a bending dead angle of the door leaf 12 to be bent, the pressing area is effectively increased, the bending corner is smaller, and the flatness is better. After the bending is finished, the cutter body 1 is reset, and the movable cutter head 2 is synchronously reset and exits from the bending dead angle of the door leaf 12 to be bent.

According to the utility model, the movable cutter head 2 capable of extending into the bending dead angle of the door leaf 12 to be bent is arranged, so that the pressing area is effectively increased, the bending corner is smaller, and the flatness of the bent door leaf is better.

Further, as shown in fig. 3, a compression spring 9 is disposed between the connecting portion 5 and the through groove 3. Wherein, two ends of the pressure spring 9 are respectively connected with the top of the through groove 3 and the upper surface of the connecting part 5. The movable tool bit 2 rotates downwards from the inclined state to the horizontal state, the pressing spring 9 is continuously compressed, the movable tool bit 2 presses the door leaf 12 to be bent under the action of the pressing spring 9, and the movable tool bit 2 is prevented from being separated from the door leaf 12 to be bent.

Further, as shown in fig. 1, an arc-shaped groove 10 is formed in the bottom end of the tool body 1, and the arc-shaped groove 10 is matched with the fixing pin 6. When the movable tool bit 2 rotates, the fixed pin 6 synchronously rotates around the axis of the movable tool bit, and the arranged arc-shaped groove 10 can avoid the interference of the tool body 1 on the rotation of the fixed pin 6.

Further, as shown in fig. 3, an arc segment 11 is arranged on the connecting portion 5, and the arc segment 11 is attached to a groove wall of the through groove 3. Wherein the arc section 11 and the fixed pin 6 are coaxially arranged, when the movable cutter head 2 rotates, the arc section 11 at the right end can avoid the interference between the through groove 3 and the movable cutter head 2, and plays a role in guiding.

The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the utility model is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art.
