DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a riveted welded part hot shaping machine comprises a hot shaping machine body 1; an electric push rod 11 is fixedly connected to the top of the hot shaping machine body 1; a heating plate 12 is fixedly connected to the end of the electric push rod 11; a storage table 13 is fixedly connected to the middle of the hot shaping machine body 1; a plurality of support plates 14 are fixedly connected to the middle of the hot shaping machine body 1; a plurality of slide columns 15 are slidably connected to the middle of the support plates 14; a clamping plate 16 is connected to the end of the slide column 15; a plurality of first tension springs 17 are connected to the middle of the clamping plate 16; when working, first align the end of the riveted welded part to be shaped with the side of the clamping plate 16 and push it, and then the clamping plate 16 will be affected by the thrust to drive the slide column 15 to slide in the middle of the support plate 14, and when the clamping plate 16 slides, the first tension spring 17 is connected to the clamping plate 16. The extension spring 17 will be extended and retracted under the action of pressure until the riveted welded part is completely placed in the middle of the storage table 13 and the pushing can be stopped. At this time, the first extension spring 17 will rebound to a certain extent, thereby driving the clamping plate 16 to clamp the riveted welded part. Then the electric push rod 11 works and drives the heating plate 12 to move toward the storage table 13, so as to shape the clamped riveted welded part. This step can clamp and fix the riveted welded part through the mutual cooperation of the clamping plate 16 and the first extension spring 17, so as to prevent the riveted welded part from being easily affected by heating and pressure and moving during hot shaping, thereby causing the shaping result to be inaccurate and fail to achieve the expected shape and size, so that secondary shaping is required, which is time-consuming and labor-intensive.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the middle part of the support plate 14 is slidably connected with multiple groups of telescopic rods 2; one end of the telescopic rods 2 is connected to a cross plate 21; the other end of the telescopic rods 2 is connected to a pull plate 22; the bottom of the cross plate 21 is connected with multiple groups of brushes 23; during operation, when the clamp 16 clamps the riveted welded parts that need to be heat-formed, the telescopic rod 2 can be stretched out first, and then the pull plate 22 can be held and pushed. At this time, the telescopic rod 2 will be affected by the thrust and move with the cross plate 21, so that the brush 23 can clean the surface of the riveted welded parts. In this step, the dust on the surface of the riveted welded parts can be cleaned by opening the brush 23, so as to improve the effect and quality of heat forming, thereby preventing the defective products formed due to the presence of dust, resulting in the situation that the product quality inspection does not meet the standards.

[0027] like Figure 1 , Figure 2 , Figure 6 As shown, a fan 3 is connected to one side of the heat shaping machine body 1; a cross support frame 31 is fixedly connected to the middle of the fan 3; a rotating shaft 32 is rotatably connected to the middle of the cross support frame 31; a plurality of fan blades 33 are fixedly connected to the middle of the rotating shaft 32; when working, the cross support frame 31 plays a role in supporting the rotating shaft 32. When the fan 3 is needed to work, the rotating shaft 32 can be rotated first, and the rotation of the rotating shaft 32 will drive the fan blades 33 to rotate, thereby forming a certain wind force and blowing and cooling the riveted welded parts on the storage table 13. This step can play a role in cooling the riveted welded parts after heat shaping through the opening of the fan 3, thereby preventing the riveted welded parts from being affected by high temperature, causing phase change of the material and redistribution of internal stress. If the temperature is not cooled in time at this time, it is easy to cause uneven stress distribution and deformation or cracks.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the middle part of the clamping plate 16 is connected to multiple groups of spring columns 4; the ends of the spring columns 4 are connected to arc-shaped elastic plates 41; the surfaces of the arc-shaped elastic plates 41 are connected to arc-shaped friction pads 42; during operation, when the clamping plate 16 clamps the riveted welded parts, the arc-shaped friction pads 42 will contact the riveted welded parts. At this time, the arc-shaped friction pads 42 will clamp the riveted welded parts under the push of the first tension spring 17, and then the arc-shaped elastic plates 41 will deform under the thrust and the shape of the riveted welded parts. The spring columns 4 will expand and contract under the thrust and drive the arc-shaped elastic plates 41 and the arc-shaped friction pads 42 to move their positions. This step is that the shapes and sizes of various riveted welded parts are different. At this time, the arc-shaped elastic plates 41 can be used to clamp and fix riveted welded parts with different and irregular shapes, thereby further strengthening the fixing effect of the riveted welded parts. The opening of the arc-shaped friction pads 42 can increase the friction between the arc-shaped elastic plates 41 and the riveted welded parts, thereby improving the fixing effect of the arc-shaped elastic plates 41.

[0029] like Figure 2 As shown, a sound-absorbing louver 5 is fixedly connected to the side of the heat shaping machine body 1; a plurality of groups of window leaves 51 are connected to the middle of the sound-absorbing louver 5; when working, the fan 3 will generate certain noise, and the noise will be transmitted to the outside through the sound-absorbing louver 5. When the noise passes through the sound-absorbing louver 5, it will generate friction and interference with the window leaves 51, thereby reducing the noise intensity. This step can reduce the noise intensity generated by the fan 3 through the sound-absorbing louver 5, which can reduce noise pollution and provide a better working environment for the staff.

[0030] like Figure 1 , Figure 3 , Figure 4 As shown, a second tension spring 6 is connected to the middle of the pull plate 22; the end of the second tension spring 6 is connected to the middle of the cross plate 21; during operation, when the pull plate 22 is pushed, the second tension spring 6 will be stretched as the cross plate 21 moves. This step can stabilize the connection relationship between the cross plate 21 and the pull plate 22 through the action of the second tension spring 6, thereby improving the stability of the cross plate 21 when moving.

[0031] like Figure 1 , Figure 3 As shown, the ends of the slide column 15 are fixedly connected to the limit pads 7; when working, the limit pads 7 play a role in limiting the sliding trajectory of the slide column 15. This step is that when the slide column 15 slides in the middle of the support plate 14 under the action of the first tension spring 17, it is easy for the end to slide out of the support plate 14 due to the lack of restriction, thereby causing the connection between the clamping plate 16 and the support plate 14 to be unstable. At this time, the role of the limit pads 7 can reduce the occurrence of such situations.

[0032] Working principle: during operation, first align the end of the riveted welded part that needs to be shaped with the side of the clamping plate 16 and push it, and then the clamping plate 16 will be affected by the thrust to drive the sliding column 15 to slide in the middle of the support plate 14, and when the clamping plate 16 slides, the first tension spring 17 will be extended and retracted by the pressure until the riveted welded part is completely placed in the middle of the storage table 13, and the pushing can be stopped. At this time, the first tension spring 17 will rebound to a certain extent, thereby driving the clamping plate 16 to clamp the riveted welded part, and then the electric push rod 11 works and drives the heating plate 12 to move toward the storage table 13, so as to shape the clamped riveted welded part. This step can play the effect of clamping and fixing the riveted welded part through the mutual cooperation of the clamping plate 16 and the first tension spring 17, so as to prevent the riveted welded part from being clamped and fixed during operation. During heat shaping, it is easy to move due to the influence of heating and pressure, resulting in inaccurate shaping results, failing to achieve the expected shape and size, so that secondary shaping is required, which is time-consuming and laborious. During operation, after the clamp 16 clamps the riveted welded parts that need heat shaping, the telescopic rod 2 can be stretched out first, and then the pull plate 22 is held and pushed. At this time, the telescopic rod 2 will be affected by the thrust and move with the cross plate 21, so that the brush 23 can clean the surface of the riveted welded parts. In this step, the dust on the surface of the riveted welded parts can be cleaned by opening the brush 23, so as to improve the effect and quality of heat shaping, thereby preventing the defective products caused by the presence of dust, resulting in the situation that the product quality inspection does not meet the standards. During operation, the cross support frame 31 is used The fan 3 has the function of supporting the rotating shaft 32. When the fan 3 needs to work, the rotating shaft 32 can be rotated first. The rotation of the rotating shaft 32 will drive the fan blades 33 to rotate, thereby forming a certain wind force and blowing air to cool the riveted welded parts on the storage platform 13. This step can cool the riveted welded parts after heat shaping through the opening of the fan 3, so as to prevent the riveted welded parts from being affected by high temperature and causing phase change of the material and redistribution of internal stress. If the riveted welded parts are not cooled in time at this time, it is easy to cause uneven stress distribution and deformation or cracks. During operation, when the clamp 16 clamps the riveted welded parts, the arc-shaped friction pad 42 will contact the riveted welded parts. At this time, the arc-shaped friction pad 42 will clamp the riveted welded parts under the push of the first tension spring 17. Then, the arc-shaped elastic plate 41 will be deformed under the thrust and the shape of the riveted part, and the spring column 4 will expand and contract under the thrust and drive the arc-shaped elastic plate 41 and the arc-shaped friction pad 42 to move. This step is that the shapes and sizes of various riveted parts are different. At this time, the arc-shaped elastic plate 41 can clamp and fix the riveted parts with different shapes and irregular shapes, thereby further strengthening the fixing effect of the riveted parts. The opening of the arc-shaped friction pad 42 can increase the friction between the arc-shaped elastic plate 41 and the riveted part, thereby improving the fixing effect of the arc-shaped elastic plate 41. When working, the fan 3 will generate certain noise, and the noise will be transmitted to the outside through the sound-absorbing shutter 5. When the noise passes through the sound-absorbing shutter 5, it will produce friction and interference with the window leaf 51.Thus, the noise intensity can be reduced. This step can reduce the noise intensity generated by the fan 3 through the sound-absorbing shutter 5, which can reduce noise pollution and provide a better working environment for the staff. When working, when the pull plate 22 is pushed, the second tension spring 6 will be stretched along with the movement of the cross plate 21. This step can stabilize the connection between the cross plate 21 and the pull plate 22 through the action of the second tension spring 6, thereby improving the stability of the cross plate 21 when moving. When working, the limit pad 7 plays a role in limiting the sliding trajectory of the slide column 15. This step is that when the slide column 15 slides in the middle of the support plate 14 under the action of the first tension spring 17, it is easy for the end to slide out of the support plate 14 due to the lack of restriction, thereby causing the connection between the clamping plate 16 and the support plate 14 to be unstable. At this time, the limit pad 7 can reduce the occurrence of such a situation.
