[0002] The utility model patent with the publication number of CN214184729U and the theme name of sheet metal part bending die has an IPC classification number of B21D5 / 02. Its technical solution discloses that "when forming, first place the rectangular plate on the top of the two supporting parts 32, support the rectangular plate through the two supporting parts 32, then the upper die base 4 moves downward, the two upper pressing plates 6 first press on the rectangular plate, and then the lower die 3 moves downward together until the upper die 5 is inserted into the forming part 31 to complete the forming of the sheet metal part. After forming, the upper die base 4 moves upward, and under the action of the spring, the lower die 3 also moves upward, so that the height of the sheet metal part is higher than the top of the lower die base 2. Even if the sheet metal part is embedded in the lower die 3, it can be taken out from the side of the lower die 3, so that after the sheet metal part is clamped into the lower die 3, it can also be easily taken out".

[0028] Embodiment 1.

[0029] Preferably, the sheet metal bending and forming die is used for bending and forming a sheet metal part 1 (as an example, Figure 11 the sheet metal part 1 in

[0030] Support mechanism 120. The support mechanism 120 includes a first support plate 121, a sleeve rod 122, a sleeve 123, a support platform 124, a second support plate 125, and a support column 126. One end of the sleeve rod 122 is fixedly connected to the first support plate 121, and the other end of the sleeve rod 122 is movably connected to one end of the sleeve 123. The other end of the sleeve 123 is fixedly connected to the lower edge of the support platform 124. The second support plate 125 is fixedly connected to the first support plate 121, and the second support plate 125 is fixedly connected to the support column 126. When the lifting mechanism 130 applies force to the support mechanism 120, it drives the support mechanism 120 and a part of the rolling mechanism 140 located on the support mechanism 120 to lift and lower (specifically, the lifting of the first rollers 141 on both sides. The position of the second roller 145 in the middle remains fixed and does not lift or lower), so as to manually adjust the contact angle between the rolling mechanism 140 and the sheet metal part 1 (the sheet metal part 1 is in contact with the first rolling shaft 143 and the second rolling shaft 147 at the same time), thereby changing the bending and forming angle of the sheet metal part 1.

[0031] Lifting mechanism 130. The lifting mechanism 130 includes a lifting cylinder 131, a hand rocker 132, and a transmission structure 133. The hand rocker 132 is in transmission connection with the transmission structure 133, the transmission structure 133 is in transmission connection with the lifting cylinder 131, and the lifting cylinder 131 is movably connected to the support platform 124. The support platform 124 can move longitudinally back and forth. The rotational movement of the hand rocker 132 is converted into the linear movement of the lifting cylinder 131 through the transmission structure 133, and then the support mechanism 120 and the rolling mechanism 140 located on the support mechanism 120 are driven to lift and lower by applying force to the hand rocker 132.

[0032] Rolling mechanism 140. The rolling mechanism 140 includes a second roller 145 and two first rollers 141. The first rollers 141 are fixedly connected to the support platform 124, and the second roller 145 is fixedly connected to the support column 126. The second roller 145 is always fixedly connected to the top end of the support column 126, so that the relative height of the second roller 145 always remains unchanged, which is convenient for adjusting the relative height of the first rollers 141 on both sides, so as to manually adjust the contact angle between the rolling mechanism 140 and the sheet metal part 1.

[0033] Among them, the first roller 141 includes a first end cover seat 144, a first rolling shaft 143, and first end covers 142 located on both sides of the first rolling shaft 143. The first rolling shaft 143 is rotatably connected to the first end cover 142, the first end cover 142 is fixedly connected to the first end cover seat 144, and the first end cover seat 144 is fixedly connected to the support platform 124.

[0034] Among them, the second roller 145 includes a second end cap seat 148, a second roller shaft 147, and second end caps 146 located on both sides of the second roller shaft 147. The second roller shaft 147 is rotatably connected to the second end caps 146, the second end caps 146 are fixedly connected to the second end cap seat 148, and the second end cap seat 148 is fixedly connected to the support column 126.

[0035] Among them, the sheet metal bending and forming die further includes a driving mechanism 110. The driving mechanism 110 includes a driving wheel 111. The second roller shaft 147 is provided with a second roller shaft extension 112, and the driving wheel 111 is fixedly connected to the second roller shaft extension 112. By applying force to the driving wheel 111, the second roller shaft 147 can be driven to rotate relative to the second end caps 146, thereby driving a change in the stroke of the sheet metal part 1.

[0036] Among them, the transmission structure 133 can be specifically implemented as one of a gear transmission structure, a lead screw transmission structure, and a worm and worm gear transmission structure, which will not be elaborated further.

[0037] Among them, the support mechanism 120 further includes a third support plate 127. The third support plate 127 is fixedly connected to the second support plate 125, and the third support plate 127 is fixedly connected to the transmission structure 133.

[0038] It is worth mentioning that the specific transmission method and other technical features of the lead screw transmission structure involved in the patent application of the present utility model should be regarded as the prior art. The specific structure, working principle, possible control methods, and spatial arrangement methods of these technical features can be selected conventionally in the art and should not be regarded as the inventive point of the patent of the present utility model. The patent of the present utility model will not be further specifically elaborated.

[0039] For those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
