[0002] Automobile covering parts refer to the spatially shaped surface or internal parts made of metal sheets that cover the engine, chassis, cab, and body. According to their functions and locations, they can be divided into three categories: external covering parts, internal covering parts, and frame covering parts.

[0003] The basic processes of stamping and forming automobile panels are: blanking, pre-bending, drawing, trimming, punching, flanging, shaping, etc. A typical structure of automobile panels generally requires 4 to 6 processes, and some processes can be combined as needed, such as blanking and drawing, trimming and punching, flanging and shaping, etc.

[0004] Traditional flanging mechanisms can be divided into two types: one is to stamp and flanging the cover through a die, and the other is to rotate the guide (such as a guide wheel or a guide plate) along the outer ring of the cover and flanging the contact part with the cover during the movement. However, since the guide needs to move along the outer ring of the cover, the contact time between the guide and the flanging part of the cover is short, and it is impossible to continuously squeeze the flanging part of the cover, which makes it easy for some covers to have incomplete flanging.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] See also Figure 1-Figure 4 As shown, a side flanging rotation mechanism for an automobile cover is provided, comprising a plurality of support rods 101 and a plurality of limiting mechanisms 120 arranged on the top of a workbench 100, wherein the plurality of support rods 101 are all located directly below a cover body 200, and are used to support and limit the bottom of the cover body 200; the plurality of limiting mechanisms 120 are arranged around the outer ring of the cover body 200; a flanging component 150 that can move along the outer ring track of the cover body 200 is also arranged on the top of the workbench 100, and the flanging component 150 includes a guide plate 152 (see Figure 7 ) and a driving member, the guide plate 152 has a guide surface that transitions from horizontal to vertical, so as to flanging the to-be-flanged portion 201 of the cover body 200 when the flanging member 150 moves along the outer circle track of the cover body 200;

[0042] The limiting mechanism 120 includes a pressure rod 131 and a movable part 130 connected to the pressure rod 131, and the pressure rod 131 has a first position and a second position; under normal conditions, the pressure rod 131 is in the first position, in which the pressure rod 131 is against the top of the cover body 200, and cooperates with the support rod 101 to fix the cover body 200; when the guide plate 152 completes the flanging of a part of the cover body 200 during the movement, the driving member drives the movable part 130 corresponding to the completed flanging part to move, so that the movable part 130 drives the pressure rod 131 to switch from the first position to the second position, and in the second position, the pressure rod 131 moves from the top of the cover body 200 to the outer ring of the flanging part 202, continuously limiting the flanging part 202.

[0043] That is, since the pressure rod 131 is set to be movable, the position of the pressure rod 131 can be switched between the top and the outer ring of the cover body 200. Therefore, when the guide plate 152 completes the flanging of the part of the cover body 200, the pressure rod 131 originally at the top of the cover body 200 is moved to the outer ring of the flanging part 202 by controlling the movement of the pressure rod 131, thereby realizing continuous restriction of the flanging part 202 and reducing the phenomenon of inadequate flanging.

[0044] like Figure 2As shown, multiple support rods 101 are respectively located at different positions at the bottom of the cover body 200, and the shape of the top of the support rod 101 matches the shape of the bottom of the cover body 200, which is used to limit the cover body 200 and prevent the cover body 200 from displacement. In addition, the tops of the multiple support rods 101 are commonly connected to a limiting ring 110, the shape of the outer ring of the limiting ring 110 matches the shape of the outer ring of the cover body 200, and is located below the bend of the cover body 200 when it is flanging (refer to Figure 4 and Figure 5 ), to provide support for the bending part of the cover body 200.

[0045] like Fig. 9 As shown, the flanging component 150 includes a connecting rod 151 slidably arranged on the top of the workbench 100, and a guide plate 152 is fixedly connected to one end of the top of the connecting rod 151 facing the cover body 200, and a rack 156 is fixedly connected to one side of the outer circle of the connecting rod 151 facing the limiting mechanism 120; wherein, the two ends of the guide plate 152 are respectively a horizontal plate 153 and a vertical plate 154, and the horizontal plate 153 and the vertical plate 154 are connected by an arc plate 155, and the horizontal plate 153 is at one end of the connecting rod 151 in the forward direction.

[0046] like Fig.10 As shown, the limiting mechanism 120 also includes a vertical rod 121 fixedly arranged on the top of the workbench 100, a horizontal rod 122 is fixedly arranged on the top of the vertical rod 121 facing the side of the cover body 200, a rotating shaft 123 is arranged at the horizontal rod 122 and vertically penetrates the horizontal rod 122, the rotating shaft 123 is rotatably connected with the horizontal rod 122, a gear 125 is fixedly arranged at the bottom end of the rotating shaft 123, and a traction plate 124 for driving the moving part 130 to move is fixedly arranged at the top end. Among them, the gear 125 is in the movement path of the rack 156, and is used to mesh with the rack 156 when the rack 156 moves to the gear 125. A top plate 127 with one end facing the cover body 200 is also fixedly arranged at the top of the horizontal rod 122, and a bevel 128 is arranged at the end of the top plate 127, which is higher at one end facing the cover body 200 and lower at one end away from the cover body 200. One end of the cross bar 122 close to the cover body 200 is provided with a penetrating slide slot 129 .

[0047] like Fig.10 and Fig.12As shown, the movable component 130 includes a slider 132 slidably set in the slide groove 129, and a bottom rod 133 that slides longitudinally through the slider 132. The bottom end of the bottom rod 133 is fixedly connected to the pressure rod 131, and a groove is opened at the top; a top rod 134 is longitudinally slidably set in the groove, and the top end is against the bottom of the top plate 127. A compression spring 135 is arranged between the bottom end of the top rod 134 and the inner end of the groove to elastically connect the two. An insertion rod 136 is fixedly set at one end of the cross bar 122. The insertion rod 136 has an "L"-shaped structure, and the bottom end of the insertion rod 136 slides through the bottom pressure rod 133; the end of the slider 132 facing the traction plate 124 is fixedly connected to a driven rod 137 with one end bent downward.

[0048] exist Fig. 9 and Fig.10 In the embodiment, the bottom rod 133 is connected to one end of the pressure rod 131 close to the advancing direction of the flange component 150; the connecting rod 151 is connected to one end of the rack 156 close to the advancing direction of the flange component 150. In this way, when the guide plate 152 completes the flange of the bottom area of ​​the pressure rod 131, the rack 156 will contact the gear 125, so that the pressure rod 131 can be controlled to move downward in this state, see the working principle for details.

[0049] Among them, when the slider 132 moves to one end of the slide groove 129, the bottom rod 133 disengages from the insertion rod 136, and the side of the pressure rod 131 close to the inside of the cover body 200 is aligned with the outer circle of the flanged part 202 in the vertical direction, so that the pressure rod 131 can be attached to the outer circle of the flanged part 202 after moving downward, thereby restricting the flanged part 202.

[0050] like Fig.11 As shown, an arc-shaped arm 126 is fixedly connected to one side of the traction plate 124 , the inner circle of the arc-shaped arm 126 is narrow at the end and wide at the connection part with the traction plate 124 , and the bent end of the driven rod 137 is on the rotation path of the arc-shaped arm 126 .

[0051] Working principle:

[0052] Combination Fig.13As shown, when the connecting rod 151 moves, the connecting rod 151 drives the guide plate 152 to move along the trajectory of the outer circle of the cover body 200. During the movement, the horizontal plate 153 is located at the top of the part to be flanged 201. As the guide plate 152 moves, the arc plate 155 contacts the part to be flanged 201, and uses its own arc surface to drive the part to be flanged 201 to flip downward, and then the flipped part to be flanged 201 is restricted by the vertical plate 154. When the connecting rod 151 moves to the rotating shaft 123, the rack 156 meshes with the gear 125. At this time, the rack 156 moves to drive the gear 125 to rotate. The gear 125 rotates through the rotating shaft 123 to drive the traction plate 124 to rotate. The traction plate 124 rotates to hook the bent end of the driven rod 137 through the arc arm 126, and uses the arc surface to pull the driven rod 137 toward the traction plate 124. The driven rod 137 moves to drive the slider 132 to move. The slider 132 drives the bottom rod 133 and the top rod 134 to move. The bottom rod 133 drives the pressure rod 131 to move toward the outer ring of the cover body 200. The top rod 134 moves downward through the bevel 128 during the movement, and the bottom rod 133 does not engage with the insertion rod 131 during the movement. 6 is disengaged, so the bottom rod 133 will not slide down, and the compression spring 135 is compressed at this time; when the slider 132 moves to one end of the slide groove 129, the bottom rod 133 is disengaged from the insertion rod 136, and at the same time, the side of the pressure rod 131 close to the inside of the cover body 200 is aligned with the outer ring of the flanged part 202 in the vertical direction. At this time, the compression spring 135 in the compressed state rebounds to push the bottom rod 133 downward, and the bottom rod 133 moves downward to drive the pressure rod 131, and the pressure rod 131 moves down to the outer ring of the flanged part 202, and the elasticity of the compression spring 135 is used to overcome the elasticity of the flanged part 202, so that the flanged part 202 is restricted to the outer ring of the limiting ring 110, thereby realizing the continuous limitation of the flanged part 202.

[0053] It can be seen that when the cover body 200 is flanged, the pressure rod 131 originally pressed on the top of the part to be flanged 201 will automatically move to the outer circle of the flanged part 202, so that the pressure rod 131 automatically detaches from the top of the cover body 200, so that after the cover body 200 completes all flanging, the cover body 200 can be quickly removed, thereby improving the unloading efficiency of the cover body 200.

[0054] At the same time, in order to improve the effect of limiting the flanged portion 202 , the shape of the side of the pressure rod 131 close to the inside of the cover body 200 is consistent with the shape of the outer circle of the flanged portion 202 .

[0055] Next, in order to achieve rapid movement of the connecting rod 151, as Figure 6-Figure 8As shown, a plurality of slideways 140 are provided through the top of the workbench 100, and the shapes of the plurality of slideways 140 correspond to the tracks of the outer ring of the cover body 200, and a connecting rod 151 is slidably provided in each slideway 140; a number of motors 141 corresponding to the number of slideways 140 are provided on the top of the workbench 100, and the output shaft of the motor 141 passes through the workbench 100, and is coaxially connected to a lever 142 located below the workbench 100, and a longitudinally penetrating empty groove 143 is provided on the top of the lever 142, and the bottom end of the connecting rod 151 extends into the empty groove 143. At the same time, a protrusion is provided on the inner wall of the slideway 140, and a notch slidably connected to the protrusion is provided at the position corresponding to the protrusion of the connecting rod 151.

[0056] When in use, the motor 141 is powered on, and the output shaft of the motor 141 drives the lever 142 to rotate. Since the bottom end of the connecting rod 151 is located in the empty slot 143, when the lever 142 rotates, the connecting rod 151 is pushed through the empty slot 143, so that the connecting rod 151 moves in the slide 140. The shape of the slide 140 corresponds to the trajectory of the outer ring of the cover body 200, so the movement route of the connecting rod 151 will also correspond to the trajectory of the outer ring. At this time, the connecting rod 151 will continue to drive the guide plate 152 to flange the outer ring of the cover body 200.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
