Description

Technical Field

[0001] The invention relates to the technical field of bending machines, in particular to a profile auxiliary positioning type bending and forming machine. Background Art

[0002] Ladders are usually assembled from multiple profiles, and some profiles on the ladder need to be processed into specific bending shapes for easy connection. In the past, when bending the profiles, manual cooperation with machines was required. Manual participation in bending not only has low work efficiency, but also poses a risk of safety accidents. Therefore, in order to improve the efficiency of bending and forming profiles, corresponding bending and forming machines are used to automatically bend the profiles.

[0003] For example, the announcement date is: 2020-06-30, the patent name is: An aluminum profile bending device, and the announcement number is: Chinese patent CN210876909U, which includes a chassis, a platform is fixedly installed on the upper side of the chassis, a hydraulic cylinder is fixedly installed on the left side of the upper surface of the platform, a movable mold is fixedly installed on the right end of the hydraulic cylinder push rod, and a fixed mold is fixedly installed on the right side of the upper surface of the platform. A heating device is installed inside the fixed mold, and the heating device includes grooves evenly opened on the right surface of the fixed mold and the left surface of the movable mold, a groove is opened on the central axis of the movable mold and the fixed mold, and two grooves are equidistantly opened on the front and rear sides of the groove on the central axis, a heating rod is fixedly installed inside the groove, and a temperature sensor is fixedly installed on the upper surface of the fixed mold and the movable mold.

[0004] The above-mentioned prior art has the following technical problems: when the existing bending device bends the profile, the heating device heats the part to be bent to enhance the plasticity of the material, making the material easier to deform during the bending process and reducing the deformation resistance. However, when the fixed mold is heated, it is not convenient to store heat. When the profile is bent and formed and the next profile to be bent is replaced, the heat is easily dissipated quickly, resulting in the heating device consuming more electrical energy to maintain the required heating temperature, which increases the overall energy loss.

[0005] For example, the Chinese patent with the announcement number of 2020-02-07, the patent name of a bending device for metal profiles, and the announcement number of CN110756630A, includes a base, the top of the base is fixedly connected to a box body, and a driving mechanism is arranged at the bottom of the back of the inner cavity of the box body, and the driving mechanism includes a mounting plate, the front of the mounting plate is fixedly connected to a reduction motor, and the output end of the reduction motor is fixedly connected to a driving wheel. By setting the base, box body, driving mechanism, rotating shaft, adjustment mechanism, bearing seat, first rolling wheel, support plate, second rolling wheel, slide plate, limit groove and limit block, the advantage of easy adjustment of curvature is achieved; The above-mentioned prior art has the following technical problems: when the existing bending device is used to bend the profile, it is not convenient to play an auxiliary positioning role on the side of the profile, and the profile can only be bent and formed by the downward movement of the pressure head. However, when the pressure head moves downward, the profile is easily laterally displaced during stamping due to the lack of a lateral auxiliary positioning structure. When the profile is displaced, the overall bending effect is greatly reduced, and even the problem of the workpiece bending not meeting the standard may occur.

[0006] Therefore, we proposed a profile auxiliary positioning bending machine to solve the above problems. Summary of the invention

[0033] When bending profiles, heating the profiles can bring many benefits, which are mainly reflected in improving the plasticity of the material and ensuring the processing quality. 1. Improve material plasticity Heating can reduce the hardness of the profile, increase its plasticity, and make it easier to bend. This is because heating can accelerate the molecular movement inside the material and reduce the bonding force between molecules, making the material more likely to deform. Especially for profiles with high hardness and poor plasticity, such as aluminum alloys and steel plates, heating can significantly improve their bending performance. 2. Ensure processing quality During the bending process, heating control helps to reduce the internal stress of the profile and prevent cracks or deformation during the bending process. Heating can also make the profile more evenly stressed during bending, thereby improving the accuracy and consistency of the bending angle and ensuring the processing quality. Based on the above-mentioned benefits of heating the bending part of the profile during the bending process, the present application also sets up a corresponding heating structure, and the present embodiment discloses the following working principle: When the profile needs to be bent, the profile to be bent is placed on the mounting plate 3, with both ends of the profile located above the power arm 704, and then the first cylinder 4 is turned on. The opening of the first cylinder 4 can cause the connecting plate 5 and the positioning pressure head 6 to move downward. After the positioning pressure head 6 moves downward, the vertical rod 901 is pressed against the profile and then moves upward. After the vertical rod 901 moves, the airflow inside the air storage column 903 can be squeezed out to the inside of the cross pipe 905 through the air guide pipe 904. The cross pipe 905 When the internal airflow increases, the pressure block 906 can be pushed to move toward the center of the connecting plate 5. After the pressure block 906 moves, the bevel can be used to squeeze the spherical end of the pressure baffle 908. The downward movement of the pressure baffle 908 can drive the heat insulation board 909 to move downward synchronously, so that the heat insulation board 909 moving downward can move to the side of the profile, thereby assisting the positioning of the side of the profile until the positioning pressure head 6 presses the middle of the profile, and then the positioning pressure head 6 is opened. The heater 8 of the part can make the positioning pressure head 6 heat up after being turned on, so that the positioning pressure head 6 is used to heat the bending part of the profile, enhance the plasticity of the material, make the material more easily deformed during the bending process, reduce the deformation resistance, and thus improve the forming quality of the bending. Then, the second cylinder 701 controls the clamping joint 703 to move downward. After the clamping joint 703 moves, the power arm 704 to which it is hinged can be tilted upward. The power arm 704 tilted at both ends of the profile and the positioning pressure head 6 can be used to press the middle part of the profile, so that the profile can be automatically bent. After the bending of the profile is completed, the positioning pressure head 6 moves upward. At this time, the vertical rod 901 is reset under the action of the first spring 902, and the heat insulation board 909 is also reset and moved upward under the action of the third spring 910. The reset heat insulation board 909 moves to the side of the positioning pressure head 6, thereby isolating the contact between the side of the positioning pressure head 6 and the outside air, reducing the heat loss of the positioning pressure head 6 during the bending idle period.

[0034] It should be noted that the heater 8 in the present application is not limited to a specific one, as long as it can meet the requirements of the production line for heating the profile, the heater 8 can be an electric heating tube heater, an electric heating plate heater or an electric heating wire heater; In the prior art, when bending the profile, there is no structure for lateral auxiliary positioning of the profile. At the same time, in order to heat the profile, the profile can only be heated. During the idle period of changing the profile bending, the mold is in contact with the outside air, which easily causes the heat to dissipate quickly. In this way, when the bent profile is subsequently heated, in order to maintain the required heating temperature, the heating device needs to perform a long-term heating process, which significantly increases the power loss of the heating device. In the bending forming machine in the present application, by setting the heat insulation plate 909, when the profile needs to be bent, the downward movement of the heat insulation plate 909 can be used to achieve auxiliary positioning of the side of the profile, so as to prevent the profile from lateral movement during bending and ensure the stability of the profile during the bending process. At the same time, after the bending is completed, the heat insulation plate 909 moves upward and resets. The reset heat insulation plate 909 moves back to the side of the positioning pressure head 6, and the contact between the side of the positioning pressure head 6 and the outside air is cut off by the heat insulation plate 909, so as to reduce the heat dissipation of the positioning pressure head 6 in the non-bending state. Therefore, two different beneficial effects can be achieved through a single heat insulation plate 909, and two different technical problems can be solved. Not only can the auxiliary lateral positioning of the profile be achieved, but also the heat loss of the positioning pressure head 6 can be reduced. Compared with the existing technology, it has significant progress and outstanding substantial characteristics.

[0035] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the basis of the above-mentioned embodiment 1. When the existing bending device bends the profile, the heating device heats the part to be bent, but it is not convenient to store heat when heating the fixed mold. When the profile is bent and formed and the next profile to be bent is replaced, the heat is easily dissipated quickly, resulting in the heating device consuming more electric energy to maintain the required heating temperature, which increases the overall energy loss. In order to solve this technical problem, this embodiment discloses the following technical content: an insulation cavity 10 is opened inside the positioning pressure head 6, and the insulation cavity 10 is filled with insulation particles. A flipping structure 11 is installed on the side of the insulation cavity 10, and the insulation plates 909 are symmetrically arranged about the transverse center axis of the positioning pressure head 6, and the symmetrically distributed insulation plates 909 are relative to the side of the positioning pressure head 6. The flipping structure 11 is fitted together, and the flipping structure 11 includes an adjusting rod 111, and the adjusting rod 111 is installed on the side of the positioning pressure head 6, and the end of the adjusting rod 111 extending into the insulation cavity 10 is fixedly installed with a flipping rack 112, and the adjusting rod 111 is connected to the positioning pressure head 6 through a fourth spring 113, and the end of the adjusting rod 111 is fixedly installed with a first magnetic block 114, and the side of the first magnetic block 114 is provided with a second magnetic block 115, and the second magnetic block 115 is embedded in the insulation board 909, the adjusting rod 111 and the positioning pressure head 6 are slidably connected, and the magnetism of the first magnetic block 114 at the end of the adjusting rod 111 is opposite to that of the second magnetic block 115, and there are multiple second magnetic blocks 115 evenly distributed on the insulation board 909 at equal intervals, and there are multiple flipping racks 112 evenly distributed on the adjusting rod 111, and multiple blades are fixed on the circumference of each flipping rack 112.

[0036] Through the heat preservation cavity 10 inside the positioning pressure head 6, when the profile is heated by the positioning pressure head 6, the heat is transferred to the heat preservation cavity 10. At the same time, the interior of the heat preservation cavity 10 is filled with a plurality of heat preservation particles. The heat preservation particles inside the heat preservation cavity 10 can absorb and store part of the heat. When the profile does not need to be bent, the heat release of the heat preservation particles inside the heat preservation cavity 10 can maintain the temperature of the positioning pressure head 6, avoiding the heat dissipation of the positioning pressure head 6 quickly, which leads to an increase in the electric energy required by the heater 8. When the insulation board 909 moves downward, the second magnetic block 115 on the insulation board 909 and the adjustment rod When the first magnetic block 114 at the end of 111 approaches each other, the magnetic attraction force when the first magnetic block 114 and the second magnetic block 115 approach each other can be used to enable the adjusting rod 111 to drive the turning rack 112 to move on the side of the positioning pressure head 6. When the insulation board 909 moves, the second magnetic block 115 thereon and the first magnetic block 114 at the end of the adjusting rod 111 move away from each other, the adjusting rod 111 returns to its original position under the action of the fourth spring 113. Therefore, the reciprocating movement of the adjusting rod 111 and the turning rack 112 can turn over the insulation particles in the insulation cavity 10, thereby improving the heat absorption and heat release effects of the insulation particles.

[0037] With regard to the prior art, in order to achieve the storage of thermal energy, corresponding thermal insulation materials are usually provided. However, after the thermal insulation materials are placed statically, the heat absorption effect of the side close to the heat source is likely to be superior to the heat absorption effect of the side far away from the heat source, which will result in the thermal insulation materials being unable to absorb heat evenly and subsequently release heat.

[0038] In response to the above problem, in the present application, when the insulation plate 909 moves downward or resets, the adjustment rod 111 drives the turning rack 112 to move back and forth to turn the insulation particles, so that the insulation particles far away from and close to the heat source can absorb heat evenly. At the same time, when releasing heat to keep the positioning pressure head 6 warm, the insulation particles can also effectively release heat.
