Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Refer to Figures 1-4 , a semi-automatic double-loop tube riveting machine, including a distribution box 1, a double-loop fixing die 6 is fixedly installed on the top surface of the distribution box 1, a double-loop heating tube 7 is installed inside the double-loop fixing die 6, a pneumatic booster cylinder 8 is fixedly installed on the top surface of the distribution box 1, a hydraulic push block 12 is fixedly connected to one side of the pneumatic booster cylinder 8, a fixing block 15 is arranged inside the double-loop fixing die 6, and a riveting slot 14 is opened on one side of the fixing block 15.

[0025] Furthermore, a double-loop tube vertical distance adjustment mechanism 10 is fixedly installed on the top surface of the distribution box 1. An electric push rod is installed inside the double-loop tube vertical distance adjustment mechanism 10, and a clamping rod adapted to the double-loop heating tube 7 is arranged on the front side of the electric push rod. By setting the double-loop tube vertical distance adjustment mechanism 10, the electric push rod and the clamping rod adapted to the double-loop heating tube 7, the user can control the clamping rod to move forward through the electric push rod and thus enter the inside of the double-loop heating tube 7, increasing the distance between the upper and lower layers of the double-loop heating tube 7, making the adaptation range of the device wider.

[0026] Even further, the specific shape of the riveting slot 14 is double "V" shape. A through slot is opened on the top surface of the double-loop fixing die 6, and the fixing block 15 is installed inside the through slot. By setting the double "V" shaped riveting slot 14, it helps to optimize the riveting quality. Precise positioning and stable support can reduce deviations and errors during the riveting process, ensuring the firmness and consistency of the riveting points. At the same time, the double V groove design can also control the deformation and stress distribution during the riveting process to a certain extent, improving the mechanical properties and durability of the riveted parts.

[0027] In addition, a pushing piece is connected to one side of the hydraulic pushing block 12. The pushing piece is located directly below the riveting fixing piece slot 13 in the initial state. One side of the pushing piece close to the double-loop heating tube 7 is arc-shaped. By setting the side of the pushing piece close to the double-loop heating tube 7 to be arc-shaped, the riveting push plate can better fit the surface of the fixing piece. Whether it is a flat fixing piece or a fixing piece with a slightly curved surface, this fit helps to reduce the gaps and unevenness during the riveting process, thereby improving the quality of riveting.

[0028] The specific number of the pneumatic booster cylinders 8 is three. The three pneumatic booster cylinders 8 are distributed in a circumferential array on the top surface of the distribution box 1. By setting the number of the pneumatic booster cylinders 8 to be three, the user can process multiple workpieces at one time.

[0029] A spring suppression mechanism 11 is fixedly connected to the top surface of the distribution box 1, and the other end of the spring suppression mechanism 11 is fixedly connected to the rear side of the hydraulic pushing block 12. By setting the spring suppression mechanism 11, after the riveting is completed, the spring suppression mechanism 11 can assist in completing the reset action, making the equipment return to the initial state for the next riveting. This reset function helps to improve the automation degree and production efficiency of the equipment, and reduces manual intervention and downtime.

[0030] During specific implementation, the user needs to first place the riveting fixing piece in the riveting fixing piece slot 13, and then start the double-loop heating tube 7 to heat the riveting fixing piece, which can improve the plasticity of the riveting fixing piece and reduce its hardness. In this way, during the riveting process, the riveting fixing piece is more likely to deform, and the formation of the head of the riveting fixing piece is easier, thereby reducing the required external force and improving the riveting effect.

[0031] After the heating of the riveting fixing piece is completed, the user can start the pneumatic booster cylinder 8. The pneumatic booster cylinder 8 will drive the hydraulic pushing block 12 and the pushing piece to move together and form an extrusion on the riveting fixing piece. At this time, the riveting fixing piece after being heated can be easily extruded and formed by the riveting slot 14 and the pushing piece, thus completing the riveting work.

[0032] By setting the pneumatic booster cylinder 8, the hydraulic pushing block 12, the double-loop heating tube 7, the riveting fixing piece slot 13 and the riveting slot 14, the user can use these devices to quickly complete the riveting work, and only one person is required to operate during the process. Compared with traditional manual riveting, this utility model does not require technicians or skilled workers to operate. According to the design technology of the present utility model, the existing manual riveting efficiency is two to three times or more that of the original skilled workers.

[0033] It should be noted that a pressure gauge 9 is provided above the pneumatic booster cylinder 8, and the presence of the pressure gauge 9 can help the user to monitor the pressure in the pneumatic booster cylinder 8 in real time.

[0034] Embodiment 2

[0035] Based on Example 1, please refer to Figures 1-4 A semi-automatic double-circle tube riveting machine, four universal wheels 2 are fixedly installed on the bottom surface of the distribution box 1, four hydraulic push rods are installed at the inner edge position of the distribution box 1, and a support plate 3 is fixedly connected to the bottom of the hydraulic push rods.

[0036] Furthermore, an air filter 4 is fixedly mounted on the side wall of the distribution box 1, and a control panel 5 is mounted on the top surface of the distribution box 1. By installing the control panel 5, the user can easily control various components in the device.

[0037] In specific implementation, the stacking position of the processed raw materials is not fixed. When there are many raw materials, a mobile device is often used to simplify the processing. However, the overall weight of the device is heavy. Conventionally, only the support plate 3 is used to fix the device, which makes the movement of the device more troublesome.

[0038] In the present invention, the user can use four hydraulic push rods installed at the inner edge of the distribution box 1 to retract the support plate 3 upward so that the support plate 3 no longer directly contacts the ground. After the support plate 3 is retracted upward, the universal wheel 2 installed on the bottom surface of the distribution box 1 will directly contact the ground. At this time, the movement of the device is transformed from the original sliding friction force to the rolling friction force that moves using the universal wheel 2, making the overall movement of the device easier.

[0039] By providing the universal wheel 2 and the support plate 3 and connecting the hydraulic push rod above the support plate 3, the device can switch between the support plate 3 contacting the ground and the universal wheel 2 contacting the ground, so that the device can take into account both convenient movement and stable support.

[0040] Working principle: the user needs to first place the riveted fixing plate in the riveted fixing plate slot 13, and then start the double-circle heating tube 7 to heat the riveted fixing plate, which can improve the plasticity of the riveted fixing plate and reduce its hardness. In this way, during the riveting process, the riveted fixing plate is easier to deform and the riveted fixing plate head is easier to form, thereby reducing the required external force and improving the riveting effect.

[0041] After completing the heating of the riveted fixing plate, the user can start the pneumatic booster cylinder 8, which will drive the hydraulic push block 12 and the push plate to move together and squeeze the riveted fixing plate. At this time, the riveted fixing plate that has been heated can be easily squeezed into shape by the riveting groove 14 and the push plate, thereby completing the riveting work.

[0042] The stacking position of the processed raw materials is not fixed. When there are many raw materials, a mobile device is often used to simplify the processing. However, the overall weight of the device is heavy. Conventionally, only the support plate 3 is used to fix the device, which makes the movement of the device more troublesome.

[0043] In this utility model, the user can retract the support disc 3 upward through four hydraulic push rods installed at the inner edge position of the distribution box 1, so that the support disc 3 no longer directly contacts the ground. After the support disc 3 is retracted upward, the universal wheels 2 installed on the bottom surface of the distribution box 1 will directly contact the ground. At this time, the movement of the device changes from the original sliding friction to the rolling friction using the universal wheels 2 for movement, making the overall movement of the device simpler.

[0044] By setting the pneumatic booster cylinder 8, hydraulic push block 12, double-loop heating tube 7, riveting fixing piece slot 13 and riveting groove 14, the user can use these devices to quickly complete the riveting work, and only one person is required to operate during the process. Compared with traditional manual riveting, this utility model does not require technicians or skilled workers to operate. According to the design technology of the present utility model, the existing manual riveting efficiency is two to three times or more that of the original skilled workers.

[0045] By setting the universal wheels 2 and the support disc 3, and connecting a hydraulic push rod above the support disc 3, the device can be switched between the support disc 3 contacting the ground and the universal wheels 2 contacting the ground, so that the device can take into account both convenient movement and stable support.
