Technical Field
[0001] The utility model relates to the technical field of aluminum-plastic cover riveting, in particular to an aluminum-plastic cover flanging type riveting head. Background Art
[0002] During the riveting process of aluminum-plastic cover, the riveting device is cylindrical, and the riveting head array is arranged on the periphery of the riveting device. It rises and falls during the self-rotation of the main body of the riveting device. Hot riveting is adopted to melt the tip at the center of the back of the plastic cover, and then with a certain force of downward pressure, the riveting head is fitted with the back of the aluminum cover, and the melted tip is formed into a disc structure, and the formed disc structure is made to cooperate with the plastic cover to bite on the aluminum cover to realize the riveting of the aluminum-plastic cover.
[0003] During the hot riveting process of the existing riveting head, the hot anchor rod is directly exposed to the air. Its surface temperature will still drop after ultrasonic heating. Therefore, in order to ensure the processing quality, the heating power will be increased, resulting in higher energy consumption of the equipment. Moreover, the hot anchor rod that is easy to dissipate heat will cause the temperature of the dust-free workshop to rise, which will affect the staff wearing anti-static dust clothing. Summary of the invention
[0004] The technical problem to be solved by the utility model is that the heat anchor rod is exposed to the air, which causes energy loss to the external heat dissipation and leads to the temperature rise of the dust-free workshop, thus affecting the working state of the staff.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an aluminum-plastic cover flanging riveting head, including a mounting rod and a heat anchor rod and an insulation shell coaxially fixed to the same end of the mounting rod, the insulation shell is sleeved on the outside of the heat anchor rod, and a truncated cone-shaped positioning boss is coaxially arranged at the movable end of the insulation shell, and the outer diameter of the positioning boss is not larger than the inner diameter of the aluminum cover.
[0006] Preferably, an annular insulation cavity is provided between the insulation shell and the thermal anchor rod.
[0007] Preferably, an adaptation gap is provided between the insulation shell and the movable end of the thermal anchor, and the adaptation gap is communicated with the insulation cavity.
[0008] Preferably, a forming groove is coaxially provided on the end wall of the movable end of the thermal anchor rod, and the cross section of the forming groove is arc-shaped.
[0009] Preferably, the radius of the outer circle of the molding groove is greater than the outer diameter of the plastic cover tip.
[0010] Preferably, the movable end of the thermal anchor rod and the movable end of the insulation shell are in the same plane.
[0011] 1. The utility model provides an aluminum-plastic cover flanging type riveting head, which is provided with a heat-insulating shell fixedly mounted on the outer ring of the heat anchor rod and ensures that the heat-insulating shell and the heat anchor rod do not contact each other, thereby heat-insulating the heat anchor rod through the heat-insulating shell, thereby reducing the loss of heat energy and avoiding temperature rise in the environment.
[0012] 2. An insulation cavity is set between the insulation shell and the heat anchor rod. The insulation cavity can be set into a sealed annular cavity structure. After the insulation cavity is evacuated, it can achieve a heat insulation effect.
[0013] 3. For the purpose of manufacturing convenience, an adaptation gap is set between the thermal anchor rod and the insulation shell, and the insulation cavity is connected through the adaptation gap to form a relatively closed annular air belt to achieve the purpose of reducing heat energy loss.

[0019] like Figure 1-3 As shown, the utility model provides an aluminum-plastic cover flanging riveting head, comprising a mounting rod 1 and a heat anchor rod 2 and an insulation shell 3 coaxially fixed to the same end of the mounting rod 1, the insulation shell 3 is sleeved on the outside of the heat anchor rod 2, and a truncated cone-shaped positioning boss 4 is coaxially arranged at the movable end of the insulation shell 3, and the outer diameter of the positioning boss 4 is not larger than the inner diameter of the aluminum cover.
[0020] The mounting rod 1 is connected to the riveting device, and the mounting rod 1 is arranged vertically. The bottom end of the mounting rod 1 is coaxially fixed with the heat anchor rod 2, and then the insulation shell 3 is put on the heat anchor rod 2, and then the insulation shell 3 is fixed on the mounting rod 1. During the hot riveting process, the riveting device drives the mounting rod 1 to move downward, and the mounting rod 1 drives the heat anchor rod 2 to move downward. The high-temperature heat anchor rod 2 moves downward and punches the aluminum-plastic cover stuck by the edge limit groove of the riveting device. The bottom end of the heat anchor rod 2 is hot-melted to the tip of the back of the aluminum-plastic cover. The tip after hot melting forms plastic and is punched into a disc structure by the hot anchor rod 2. The outer diameter of the formed disc structure is larger than the inner diameter of the middle opening of the aluminum cover for the tip to pass through, so that the disc structure cooperates with the plastic cover to clamp the aluminum cover, and the hot riveting work of the aluminum-plastic cover is completed.
[0021] The positioning boss 4 of the truncated cone structure can be smoothly inserted into the aluminum cover, and the outer wall of the positioning boss 4 can fit with the inner wall of the aluminum cover, so that the aluminum cover is fixed to the end of the positioning boss 4, thereby improving the accuracy of the heat riveting process.
[0022] like Figure 3 As shown. An annular insulation cavity 7 is provided between the insulation shell 3 and the heat anchor 2. The insulation shell 3 is arranged on the outer ring of the heat anchor 2, and the insulation shell 3 is coaxial with the heat anchor 2 to form an annular insulation cavity 7. If the insulation cavity 7 is set as a sealed cavity and the interior of the insulation cavity 7 is evacuated, heat dissipation can be reduced by eliminating the heat-conducting medium, thereby achieving the purpose of heat preservation.
[0023] like Figure 1 and Figure 3 As shown. An adaptation gap 6 is provided between the insulation shell 3 and the movable end of the heat anchor 2, and the adaptation gap 6 is connected to the insulation cavity 7. It is too costly to set the insulation cavity 7 as a sealed cavity, so by providing the adaptation gap 6 between the insulation shell 3 and the heat anchor 2, the adaptation gap 6 can prevent air convection in the insulation cavity 7, thereby reducing the loss of heat energy.
[0024] like Figure 1 and Figure 3 As shown. A molding groove 5 is coaxially provided on the movable end wall of the heat anchor rod 2, and the cross section of the molding groove 5 is arc-shaped. When the tip is hot-melted, the molding groove 5 contacts the end of the tip. After the molding groove 5 is set, the molding groove 5 is arranged slightly inside the heat anchor rod 2 to ensure that the temperature of the inner wall of the molding groove 5 is as stable as possible.
[0025] As a preferred embodiment of the utility model, the tip is hot-melted through the molding groove 5, and it is necessary to ensure that the disc-shaped structure formed by the molding groove 5 can hook the aluminum cover. The radius of the outer circle of the molding groove 5 is greater than the outer diameter of the tip of the plastic cover.
[0026] As a preferred embodiment of the utility model, the movable end of the heat anchor rod 2 is in the same plane as the movable end of the insulation shell 3. During the hot riveting process of the heat anchor rod 2, the end of the heat anchor rod 2 contacts the aluminum cover wall, and the molten plastic generated by the melting of the tip is formed in the molding groove 5.
