When the profile is bent, the profile can be heated, and the advantages are mainly reflected in the aspects of improving the plasticity of the material, ensuring the processing quality and the like;
1. improving the plasticity of the material
The hardness of the section bar can be reduced by heating, the plasticity of the section bar can be increased, so that the section bar is easier to bend, because the heating can promote the molecular movement in the material to accelerate, and reduce the bonding force between molecules, the material is easier to deform, and particularly for the section bar with higher hardness and poorer plasticity, such as aluminum alloy, steel plate and the like, the bending performance of the section bar can be obviously improved by heating;
2. Ensuring the processing quality
In the bending process, the heating control is beneficial to reducing the internal stress of the profile, preventing cracks or deformation in the bending process, and the heating can also lead the profile to be stressed more uniformly during bending, thereby improving the accuracy and consistency of the bending angle and ensuring the processing quality;
Based on the above benefits of heating the bending part of the profile in the bending process, the application also provides a corresponding heating structure, and the embodiment discloses the following working principles:
When the profile is required to be bent, the profile to be bent is placed on the carrying plate 3, two ends of the profile are positioned above the power arm 704, then the first air cylinder 4 is started, the first air cylinder 4 is started to enable the joint plate 5 and the positioning pressure head 6 to move downwards, after the positioning pressure head 6 moves downwards, the vertical rod 901 is pressed to collide with the profile and then move upwards, the vertical rod 901 moves to extrude air flow inside the air storage upright post 903 into the transverse pipe 905 through the air duct 904, after the air flow inside the transverse pipe 905 is increased, the pressing block 906 can be pushed to move towards the center direction of the joint plate 5, the spherical end part of the pressed blocking rod 908 can be extruded by utilizing the inclined edge after the pressing block 906 moves, the pressed blocking rod 908 can drive the heat insulation plate 909 to move downwards synchronously, and therefore the heat insulation plate 909 can move to the side edge of the profile by utilizing the downward movement, the side edge of the section bar is positioned in an auxiliary way until the positioning pressure head 6 presses the middle part of the section bar, then a heater 8 in the positioning pressure head 6 is started, the heater 8 can enable the positioning pressure head 6 to generate heat after being started, thereby utilizing the positioning pressure head 6 to heat the bending part of the section bar, enhancing the plasticity of materials, enabling the materials to be easier to deform in the bending process, reducing the deformation resistance, improving the bending forming quality, then controlling the clamping head 703 to move downwards through a second cylinder 701, enabling a power arm 704 which is in hinged connection with the clamping head 703 to tilt upwards after the clamping head 703 moves, automatically bending the section bar by utilizing the power arms 704 which tilt at two ends of the section bar and the compression of the middle part of the section bar by the positioning pressure head 6, after the bending of the section bar is finished, enabling the positioning pressure head 6 to move upwards, resetting under the action of a first spring 902 at the moment, and the heat insulating plate 909 is reset and moves upwards under the action of the third spring 910, and the reset heat insulating plate 909 moves to the side edge of the positioning press head 6, so that the side edge of the positioning press head 6 is isolated from contact with the outside air, and the heat loss of the positioning press head 6 in the bending idle stage is reduced.
It should be noted that, the heater 8 in the present application is not limited to a specific one, and the heater 8 may be an electrothermal tube heater, an electrothermal plate heater or an electrothermal wire heater as long as the heater can meet the requirement of the assembly line for heating the section bar;
in the prior art, when the profile is bent, a structure for laterally assisting in positioning the profile is not provided, meanwhile, in order to heat the profile, only the profile can be heated, and when the neutral period of bending the profile is replaced, after the die is contacted with outside air, heat is easy to be emitted faster, so that when the bent profile is heated in the follow-up double-bending mode, a heating device is required to perform long-time heating treatment in order to maintain the required heating temperature, and the electric energy loss of the heating device is obviously increased;
In the bending forming machine provided by the application, by arranging the heat insulating plate 909, when a profile is required to be bent, the side edge of the profile can be subjected to auxiliary positioning by utilizing the downward movement of the heat insulating plate 909, the profile is prevented from moving laterally during bending, the stability of the profile in the bending process is ensured, meanwhile, after the bending is finished, the heat insulating plate 909 moves upwards to reset, the reset heat insulating plate 909 moves to the side edge of the positioning press head 6 again, the heat insulating plate 909 cuts off the contact between the side edge of the positioning press head 6 and the outside air, and the heat emission of the positioning press head 6 is reduced in a non-bending state, so that two different beneficial effects can be realized through a single heat insulating plate 909, two different technical problems can be solved, the lateral auxiliary positioning of the profile can be realized, and the heat loss of the positioning press head 6 can be reduced.
