[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] As attached Figs. 1 to 7 As shown, this embodiment provides a bending mechanism for a bending machine, including: a platform 1, a carrier 2, a heating component, and a bending component.
[0024] In this embodiment, platform 1 is used to place platform 2. Platform 2 is set on platform 1 to support the workpiece, which includes a main body and a part to be bent connected to the main body. The number of platforms 2 can be one or at least two. To improve work efficiency, this embodiment uses four platforms 2. A heating assembly is set on platform 1 to support and heat the part to be bent. A bending assembly is located next to the heating assembly and is used to bend and pre-press the part to be bent.
[0025] In this embodiment, the stage 2 has a first air passage inside, and a plurality of first air holes 201 communicating with the first air passage are provided on the upper surface of the stage 2. The first air passage is connected to a vacuum generating device, which uses the first air holes 201 to adsorb the workpiece onto the stage 2. A positioning block 202 is provided on the upper surface of the stage 2, and the workpiece is fixed on the stage 2 by the positioning block 202. Specifically, the workpiece can be fixed by having a through hole in the workpiece, with the positioning block 202 passing through the through hole, or by having a limiting groove in the workpiece, with the positioning block 202 located in the limiting groove. A positioning groove 204 can also be provided on the upper surface of the stage 2, and the workpiece is fixed on the stage 2 by the positioning groove 204. In this embodiment, the heating assembly includes a heating element 3 and a heat transfer block 4. The heat transfer block 4 is disposed on the platform 1, and the heating element 3 is located inside the heat transfer block 4. The heating element 3 heats the heat transfer block 4, and the portion to be bent is located on the upper surface of the heat transfer block 4. Specifically, a heat insulation fixing block 5 is disposed on the lower surface of the platform 1, and the heat transfer block 4 is located between the platform 1 and the heat insulation fixing block 5. The heat transfer block 4 includes a body 401 and an extension 402. The extension 402 is disposed at one end of the body 401 and extends upward, and the portion to be bent is located on the upper surface of the extension 402. The heating element 3 can be a heating rod, which is inserted into the body 401. The heating temperature of the heating rod is 120-200 degrees Celsius, specifically 130 degrees Celsius, 140 degrees Celsius, 150 degrees Celsius, 160 degrees Celsius, 170 degrees Celsius, 180 degrees Celsius, or 190 degrees Celsius, which can be selected as needed. A temperature sensor, which can be a thermocouple, is disposed inside the body 401 of the heat transfer block 4 for temperature measurement and monitoring. The heat transfer block 4 is made of copper, which has excellent thermal conductivity.
[0026] In this embodiment, the projection of the extension 402 onto the platform 1 does not coincide with the projection of the stage 2 onto the platform 1. The main body of the workpiece is disposed on the stage 2, and the portion to be bent is located outside the upper surface of the stage 2, at least partially located on the upper surface of the extension 402. That is, the projection of the portion to be bent onto the plane of the platform 1 does not coincide with the projection of the stage 2 onto the plane of the platform 1, but the projection of the portion to be bent onto the projection of the extension 402 onto the plane of the platform 1 at least partially coincides.
[0027] Furthermore, a heat insulation seat 6 is provided between the heat transfer block 4 and the heat insulation fixing block 5, and the material of the heat insulation seat 6 is selected from synthetic stone.
[0028] To achieve better heat dissipation, a heat dissipation base 7 is provided between the stage 2 and the platform 1.
[0029] The platform 2 has a second air duct inside, and a heat dissipation hole 203 communicating with the second air duct. The second air duct is connected to an air source, which dissipates heat from the platform 2 through the heat dissipation hole 203. The second air duct can be made as long as possible within the platform 2 to achieve better heat dissipation. The second air duct can be configured in a spiral shape, a U-shape, etc., and can be arranged in layers with the first air duct to ensure that they do not interfere with each other and achieve their respective optimal effects.
[0030] Furthermore, a heat dissipation component is provided on platform 1 to dissipate heat from the stage 2. The heat dissipation component includes an air blowing pipe 8 and an air source. The air blowing pipe 8 is connected to the air source through a pipe and is fixed to platform 1 by an air blowing pipe base 9. The air outlet of the air blowing pipe 8 faces the stage 2, and heat dissipation is achieved by the flow of air.
[0031] In this embodiment, the bending assembly includes a bending rod 10 and a drive mechanism for driving the bending rod 10. In this embodiment, the movement of the bending rod 10 is a rotational movement. The drive mechanism can be a motor, whose output shaft is connected to a drive wheel 11, and one end of the bending rod 10 is connected to a driven wheel 12. The drive wheel 11 and the driven wheel 12 are connected by a belt, thereby realizing the drive mechanism driving the rotational movement of the bending rod 10.
[0032] The bending rod 10 has an initial state and a working state. When the bending rod 10 is in the initial state, the upper end face of the head of the bending rod 10 is located below the part to be bent. When the bending rod 10 is in the working state, the drive mechanism drives the bending rod 10 to move, thereby causing at least part of the part to be bent to bend, and the bent part is confined between the bending rod 10 and the top of the extension 402. That is, when the bending rod 10 is in the initial state, the part to be bent of the workpiece is located outside the upper surface of the platform 2, and is located on the upper surface of the extension 402 and the upper end face of the head of the bending rod 10, and at this time the extension 402 is located between the platform 2 and the head of the bending rod 10. When the bending rod 10 is in the working state, the drive mechanism drives the bending rod 10 to rotate from bottom to top, thereby causing the end of the part to be bent to bend upward and inward, and the bent part is confined between the head of the bending rod 10 and the top of the extension 402.
[0033] In this embodiment, the bending rod 10 is integrally formed. A third air passage is provided inside the bending rod 10, and a second air hole 101 communicating with the third air passage is provided on the head end face of the bending rod 10. The third air passage is connected to a vacuum generating device, and the vacuum generating device adsorbs the part to be bent through the second air hole 101.
[0034] In this embodiment, platform 1 is mounted on carrier base plate 13 via a support plate. An electric slide assembly 14 is mounted on carrier base plate 13, and a drive mechanism is mounted on the electric slide assembly 14. The electric slide assembly 14 adjusts the forward / backward and left / right positions of the drive mechanism. An electric cylinder assembly 15 may also be mounted on carrier base plate 13, with the electric slide assembly 14 mounted on it. The electric cylinder assembly 15 cooperates with a slide rail mounted on carrier base plate 13 to adjust the vertical position of the electric slide assembly 14, thereby adjusting the positions of the drive mechanism and bending rod 10. The electric slide assembly 14 and electric cylinder assembly 15 are conventional methods and will not be described in detail here.
[0035] In this embodiment, the bending mechanism only heats the bending part and adds a heat dissipation component to prevent the product from discoloring due to heat, thereby improving product quality.
[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
