[0034] The following is a further detailed description of this application in conjunction with the specific content. Example

[0035] A semi-automatic double row hot riveting machine, such as Figure 1 and Figure 2 As shown, the hot riveting machine includes a main body 1, which includes a workbench 11 with a window 12 on one side. The workbench 11 is provided with a plurality of translation guide rails 2, to which sliding blocks 21 are slidably connected. A translation lower template 22 is fixedly connected on the side of the sliding block 21 away from the workbench 11, and a lower film 23 is bolted to the translation lower template 22. A translation assembly is provided on the workbench 11 to drive the translation lower template 22 to move along the translation guide rails 2. In the initial state of the hot riveting machine main body 1, the translation lower template 22 is located near the window 12.

[0036] like Figure 2 and Figure 3 As shown, two horizontal plates 3 are provided above the translation lower template 22, and the horizontal plates 3 are perpendicular to the translation guide rails 2. Four downward pressure cylinders 31 are mounted on each of the horizontal plates 3. The piston rods of the downward pressure cylinders 31 are fixedly connected to connecting rods 311, which are fixedly connected to connecting plates 312. An upper membrane mounting member 313 is fixedly mounted on the end of the connecting plate 312 near the workbench 11. An upper membrane 314 is mounted on the side of the upper membrane mounting member 313 near the workbench 11. When the hot riveting machine body 1 is in the initial state, the piston rods of the downward pressure cylinders 31 are in a retracted state.

[0037] When the hot riveting machine body 1 is working, the product plastic is positioned and installed on the lower film 23. After the upper film 314 is heated to the specified working temperature by the thermal resistor, the translation assembly drives the translation lower template 22 along the translation guide 2 to translate the lower film 23 to below the upper film 314. Then, the downward pressure cylinder 31 drives the connecting rod 311 to move downward. The connecting rod 311 drives the connecting plate 312 and the upper film mounting member 313 to move downward. The upper film mounting member 313 drives the upper film 314 down to fit with the lower film 23. At this time, the high temperature of the upper film 314 hot-rivets the product plastic. After the holding time is reached, the downward pressure cylinder 31 drives the upper film 314 upward to the initial position. Then, the translation assembly drives the translation lower template 22 along the translation guide 2 back to the position near the window 12. The staff can remove the solidified product, thus completing the plastic hot riveting molding.

[0038] like Figure 2 and Figure 3As shown, the translation assembly includes a translation screw 4 fixedly mounted on the workbench 11, parallel to the translation guide rail 2. A translation block 41 (not shown) is threadedly connected to the translation screw 4 and fixedly connected to the translation lower template 22. A translation motor 42 is fixedly mounted on the side of the workbench 11 away from the window 12. The translation motor 42 and the translation screw 4 are driven by a belt.

[0039] After the plastic is placed on the lower film 23, the translation motor 42 is turned on, driving the translation screw 4 to rotate. The translation screw 4 drives the translation block 41 along the translation screw 4 to move the translation lower template 22 to the bottom of the pressing cylinder 31. After the hot riveting is completed, the translation motor 42 is turned on, driving the translation screw 4 to rotate, thereby moving the translation lower template 22 to a position close to the window 12.

[0040] like Figure 4 and Figure 5 As shown, the connecting rod 311 is a threaded rod, on which a first locking block 3111 and a second locking block 3112 are threadedly connected. The connecting plate 312 is provided with a through hole 3121 that is plugged into the first locking block 3111. A notch 3122 with the same width as the connecting rod 311 is provided on the side of the through hole 3121 near the connecting rod 311. When installing the connecting plate 312, the first locking block 3111 is screwed onto the end of the connecting rod 311, and then the first locking block 3111 is inserted into the through hole 3121 from the side. At the same time, the connecting rod 311 between the first locking block 3111 and the second locking block 3112 is inserted into the notch 3122. The second locking block 3112 is then tightened against the connecting plate 312, and the connecting plate 312 is then installed on the connecting rod 311.

[0041] like Figure 5 As shown, the downward pressure cylinder 31 is mounted on the vertical plate 5. A pair of vertical guide rails 51 are fixed to the side of the vertical plate 5 near the connecting plate 312. Sliders 52 are slidably connected to the vertical guide rails 51 and fixed to the connecting plate 312. When the downward pressure cylinder 31 drives the piston rod up and down, the connecting plate 312 moves up and down along the vertical guide rails 51 via the slides 52. The provision of the vertical guide rails 51 ensures that the upper film 314 maintains balance during its up and down movement, thereby improving the plastic hot riveting forming efficiency.

[0042] like Figure 3 and Figure 6 As shown, the transverse plate 3 is equipped with a transverse adjustment assembly that moves the downward pressure cylinder 31 laterally along the transverse plate 3. The transverse adjustment assembly includes two pairs of end plates 6 fixedly mounted on the transverse plate 3. Each pair of end plates 6 is rotatably connected to two transverse screws 61, which are arranged vertically. Two transverse adjustment motors 62, arranged vertically, are fixedly mounted at each end of the transverse plate 3 and are fixedly connected to the two transverse screws 61.

[0043] like Figure 3 and Figure 6 As shown, an orienting plate 7 is fixedly connected to the horizontal plate 3. The orienting plate 7 is provided with two transverse strip holes 71, which are parallel to the workbench 11. An adjustment block 72 is threadedly connected to the transverse lead screw 61. One end of the adjustment block 72 passes through the strip holes 71 and is fixedly connected to the vertical plate 5. The adjustment block 72 farther from the workbench 11 also passes through the transverse lead screw 61 below.

[0044] If the product to be hot-riveted changes in size along the horizontal plate 3, the lower film 23 is first replaced. Then, the horizontal adjustment motor 62 is turned on to drive the adjustment block 72 along the horizontal screw 61. The adjustment block 72 drives the vertical plate 5 along the strip hole 71, and the vertical plate 5 drives the downward pressure cylinder 31 to move horizontally to a position that is suitable for the product. The adjustment block 72, which is away from the workbench 11, also passes through the horizontal screw 61 below, which can increase the stability of the downward pressure cylinder 31 during lateral movement.

[0045] like Figure 5 As shown, the side of the orienting plate 7 near the downward pressure cylinder 31 is provided with a directional guide rail 73 parallel to the workbench 11. The side of the vertical plate 5 near the orienting plate 7 is fixed with an orienting block 74 that is slidably connected to the directional guide rail 73. The arrangement of the orienting block 74 and the directional guide rail 73 can serve as a lateral limit for the downward pressure cylinder 31.

[0046] like Figure 3 and Figure 7 As shown, longitudinal adjustment components are provided on both sides of the transverse plate 3 to move the downward pressure cylinder 31 longitudinally perpendicular to the transverse plate 3. The longitudinal adjustment component includes an adjustment frame 8 provided on both sides of the transverse plate 3, and the adjustment frame 8 is fixed on the workbench 11. The adjustment frame 8 includes a longitudinal plate 81, on which two adjustment guide rails 82 are provided, and two positioning blocks 83 are slidably connected to the adjustment guide rails 82, and the two positioning blocks 83 are fixedly connected to the two transverse plates 3 on the side away from the workbench 11. A longitudinal lead screw 84 is threadedly connected to the positioning block 83 on one of the longitudinal plates 81, and a bottom block 85 is threadedly connected to the longitudinal lead screw 84, and the bottom block 85 is fixedly connected to the positioning block 83. A longitudinal adjustment motor 86 is installed at each end of the longitudinal plate 81 to drive the longitudinal lead screw 84 to rotate through a belt drive.

[0047] When the size of the product that needs hot riveting changes along the direction of the longitudinal plate 81, the lower membrane 23 is first replaced, and then the longitudinal adjustment motor 86 is started, the longitudinal screw 84 rotates, driving the bottom block 85 to move along the screw, and the bottom block 85 drives the positioning block 83 to move along the adjustment guide rail 82. The positioning block 83 drives the two horizontal plates 3 to move closer to or away from each other, thereby realizing the position adjustment of the downward pressure cylinder 31 along the direction of the longitudinal plate 81.

[0048] The implementation principle of a semi-automatic double-row hot riveting machine in the embodiment of the present application is as follows: when the hot riveting machine body 1 is in operation, the product plastic is positioned and installed on the lower film 23. After the upper film 314 is heated to the specified working temperature by the thermal resistor, the translation motor 42 drives the translation lower template 22 along the translation guide rail 2 to translate the lower film 23 to below the upper film 314. Then, the downward pressure cylinder 31 drives the upper film 314 down to fit with the lower film 23. At this time, the high temperature of the upper film 314 hot-rivets the product plastic. After the holding time is reached, the downward pressure cylinder 31 drives the upper film 314 upward to the initial position. Then, the translation motor 42 drives the translation lower template 22 back to the position near the window 12. The staff can remove the solidified product, thus completing the plastic hot riveting forming.

[0049] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
