[0002] During the production of logistics containers with high strength and load-bearing requirements, stamping is required. The side plates of the material box are formed into wavy reinforcing ribs through stamping to enhance the structural strength of the material box and meet the high load-bearing requirements.

[0003] For example, a sheet metal stamping expansion fixing device with the publication number CN216441518U can, through the coordinated use of a wedge block, a convex ring, a punching groove, a convex column, a conical hole, etc., generate extrusion through the wedge block to cause a primary stamping expansion of the convex ring and the punching groove, and cooperate with the secondary stamping expansion of the convex column and the conical hole to improve the connection strength between the sheet metal bodies, with a high degree of automation. However, in actual use, during the stamping process of the logistics container sheets, it is not convenient to load and unload the sheets. The sheets need to be positioned first and then placed during the stamping process. After stamping, the sheets need to be taken out of the mold first and then loosened and removed.

[0027] By adopting the above technical solution, the spraying range of the lubricant can be expanded during the process of conveying and loading the board material.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: The fixing mechanism for stamping the board material of the logistics container enables the board material to be automatically positioned during the conveying and loading process when stamping the side board material of the logistics container, facilitating the loading of the board material during stamping. During the stamping work of the board material, it is only necessary to control the conveying structure to convey the board material, improving the continuity of the board material processing. It not only facilitates the loading of the board material during stamping, but also enables the board material to be quickly demolded from the mold after the subsequent stamping of the board material is completed, without repeatedly fixing and releasing the board material through the fixing structure. Compared with the board material stamping fixing structure in the prior art, the working efficiency of the board material stamping can be effectively improved.

[0029] 1. When stamping the side plate of the material box, the handwheel can be rotated according to the size of the plate, driving the first screw rod to rotate. While the first screw rod is rotating, the operator synchronously rotates the knob. After the first screw rod rotates, it can drive the movable plate to move, so as to adjust the distance between the two fixed frames. The spiral directions of the first screw rod and the second screw rod are opposite and the helix pitches are the same. After the movable plate moves, the movable seat moves in the opposite direction, and there is a clearance fit between the column block and the guide frame, so that the column block can remain in its original position after the fixed plate moves. When stamping the plate, the plate is placed on the two fixed frames, and then the driving motor is started to drive the threaded rod to rotate, so as to drive the movable frame to move. While the movable frame is moving, it slides on the support rod. When the movable frame moves, it can drive the two connecting frames to move. After the connecting frames move, the moving frame can be driven to move through the cross bar, so as to drive the fixed plate to move, making the column block slide in the guide frame. When the column block moves in the inclined section of the guide frame, it can drive the fixed plate to move, so as to drive the fixed frame to move. After the two fixed frames approach each other, the plate can be clamped and positioned. When the movable frame continues to move, the column block moves to the straight section of the guide frame, and the plate is driven by the movable frame to move above the lower die. Then the plate can be stamped through the stamping device. The plate is formed by the clamping of the upper die and the lower die. When stamping the plate, it drives the plate to move downward, so as to drive the fixed frame to move downward, making the moving plate slide on the fixed rod and stretch the telescopic spring. When the plate is stamped and formed, the telescopic spring can restore its deformation, so as to drive the fixed frame to rise and reset, enabling the plate to be quickly demolded. Then the driving motor drives the threaded rod to rotate in the reverse direction, so as to discharge the stamped plate. And when the fixed frame moves, the column block moves to the inclined section of the guide frame, which can automatically release the plate, facilitating the removal of the plate. Therefore, in the stamping work of the plate, only the conveying structure needs to be controlled to convey the plate, improving the continuity of plate processing. It is convenient for loading the plate during stamping and can quickly demold the plate from the mold after stamping. There is no need to repeatedly fix and release the plate through the fixing structure, which can effectively improve the working efficiency of plate stamping compared with the existing plate stamping fixing structure;

[0030] 2. When fixing the plate, the two fixed frames approach each other, making the positioning plate fit with the plate. The movement of the fixed frame makes the positioning plate move, driving the movable rod to slide on the fixed frame and deforming the reset spring. During the movement of the positioning plate, it can drive the rotating rod to move. Through the meshing of the rotating gear and the rack, the rotating rod can be driven to rotate. After the rotating rod rotates, the roller between the rotating frames rotates downward, making the roller fit with the top of the plate, so that the positioning plate can position the top of the plate while fixing the plate, avoiding the plate from warping and improving the fixing effect of the plate;

[0031] 3. After the sheet is fixed, when it is conveyed and loaded, it can be driven to pass between the two sets of support plates. The two rollers are in contact with each other, and the tension spring is in a stretched state. The top height of the lower roller is slightly higher than the top surface height of the positioning plate. When the sheet moves through the two rollers, it can push the two support plates away from each other, causing the sliding rod to move and the tension spring to stretch further. When the sheet passes through the support plates, the rollers are in contact with the sheet. The lubricant is introduced into the connecting pipe through an external pump body, so that the two shunt pipes can be filled with the lubricant. The lubricant can be atomized and sprayed on the sheet through the nozzles on the telescopic pipes, reducing the friction between the sheet and the die during the stamping process. And when the sheet is conveyed and moves, it drives the rollers to rotate, which can drive the reciprocating lead screw to rotate. The nozzles are fixedly installed on the movable block. After the reciprocating lead screw rotates, it can drive the movable block to move reciprocally. The movement of the movable block can drive the nozzles to move reciprocally, so that the spraying range of the lubricant can be expanded during the conveying and loading process of the sheet, facilitating the subsequent stamping work of the sheet and improving the practicability.

[0047] The support rods 205 are symmetrically and slidably connected to both sides inside the movable frame 206. The two ends of the support rods 205 are respectively fixedly connected to the two mounting blocks 204. And connecting frames 207 are symmetrically installed at both ends of the movable frame 206. And a cross bar 209 is fixedly installed on the inner side of the connecting frame 207. At the same time, a movable frame 208 is slidably connected to the outside of the cross bar 209. And strip-shaped grooves 210 are respectively formed through the tops of the two movable frames 208 on the top of the workbench 1;

[0048] Vertical rods 211 are symmetrically installed on the tops of the two movable frames 208. And a fixing plate 212 is fixedly installed on the tops of the two vertical rods 211. And a mounting groove 213 is formed through the top of the fixing plate 212. At the same time, a first screw rod 214 is rotatably connected inside the mounting groove 213. And a movable plate 215 is threadedly connected to the outside of the first screw rod 214. And one end of the first screw rod 214 passes through the fixing plate 212 and is fixedly installed with a hand wheel 223. And limiting rods 216 are symmetrically and slidably connected to the lower part inside the movable plate 215. At the same time, the two ends of the limiting rods 216 are fixedly connected to the mounting groove 213;

[0049] An installation frame 217 is fixedly installed at the bottom of the movable plate 215. And a second screw rod 218 is rotatably installed inside the installation frame 217. And a movable seat 219 is screwed to the outside of the second screw rod 218. At the same time, a column block 221 is fixedly installed at the bottom of the movable seat 219. At the same time, one end of the second screw rod 218 passes through the installation frame 217 and is fixedly installed with a knob 224;

[0050] Guide rods 220 are symmetrically and slidably connected inside the movable seat 219. And the two ends of the two guide rods 220 are fixedly connected to the installation frame 217. And guide frames 222 are fixedly installed below the two movable seats 219 on the top of the workbench 1. At the same time, the column block 221 is slidably connected to the guide frame 222;

[0051] Fixed rods 225 are symmetrically installed on the top of the movable plate 215. And a movable plate 226 is slidably connected to the outside of the two fixed rods 225. And telescopic springs 227 are sleeved on the upper parts of the two fixed rods 225. At the same time, the two ends of the telescopic springs 227 are respectively fixedly connected to the fixed rods 225 and the movable plate 226. And a fixed frame 228 is fixedly installed on one side of the movable plate 226.

[0052] Example 1: As shown in Figures 1 - 7 the figure, when stamping the side plate of the material box, the hand wheel 223 can be rotated according to the size of the plate, driving the first screw rod 214 to rotate. While the first screw rod 214 rotates, the operator synchronously rotates the knob 224. After the first screw rod 214 rotates, it can drive the movable plate 215 to move, so that the distance between the two fixing frames 228 can be adjusted. And the spiral directions of the first screw rod 214 and the second screw rod 218 are opposite and the helix pitches are the same. After the movable plate 215 moves, the movable seat 219 moves in the opposite direction. And there is a clearance fit between the column block 221 and the guide frame 222, so that after the fixing plate 212 moves, the column block 221 can remain in its original position. When stamping the plate, the plate is placed on the two fixing frames 228, and then the driving motor 203 can be started to drive the threaded rod 202 to rotate, so that the movable frame 206 can be driven to move. While the movable frame 206 moves, it slides on the support rod 205. When the movable frame 206 moves, it can drive the two connecting frames 207 to move. After the connecting frames 207 move, the moving frame 208 can be driven to move through the cross bar 209, so that the fixing plate 212 can be driven to move, making the column block 221 slide in the guide frame 222. When the column block 221 moves in the inclined section of the guide frame 222, it can drive the fixing plate 212 to move, so that the fixing frame 228 can be driven to move. After the two fixing frames 228 approach each other, the plate can be clamped and positioned. Then when the movable frame 206 continues to move, the column block 221 moves to the straight section of the guide frame 222, and the plate is driven by the movable frame 206 to move above the lower die 101. Then the plate can be stamped through the stamping device. The plate is formed by the clamping of the upper die and the lower die 101. When stamping the plate, it drives the plate to move downward, so that the fixing frame 228 can be driven to move downward, making the moving plate 226 slide on the fixed rod 225 and stretch the telescopic spring 227. When the plate is stamped and formed, the telescopic spring 227 can restore its deformation, so that the fixing frame 228 can be driven to rise and reset, enabling the plate to be quickly demolded. Then the driving motor 203 drives the threaded rod 202 to rotate in the reverse direction, so that the stamped plate can be unloaded. And when the fixing frame 228 moves, when the column block 221 moves to the inclined section of the guide frame 222, the plate can be automatically released, facilitating the removal of the plate. So in the stamping work of the plate, only the conveying structure needs to be controlled to convey the plate, improving the continuity of plate processing. It is convenient for loading the plate during stamping, and the plate can be quickly demolded from the mold after stamping. There is no need to repeatedly fix and release the plate through the fixing structure. Compared with the existing plate stamping fixing structure, the working efficiency of plate stamping can be effectively improved.

[0053] On both sides inside the fixing frame 228, there are symmetrically sliding connections with movable rods 229. One end of each of the two movable rods 229 is fixedly installed with a positioning plate 230. On the outer side of each of the two movable rods 229, a return spring 231 is sleeved. At the same time, the two ends of the return spring 231 are fixedly connected to the movable rod 229 and the fixing frame 228 respectively;

[0054] On the top of the positioning plate 230, there are symmetrically installed support blocks 232. Inside the two support blocks 232, there is a rotatable connection with a rotating rod 233. On the outer side of the rotating rod 233, there are symmetrically installed rotating frames 234. Between the two rotating frames 234, there is a rotatable connection with a roller shaft 235. At the same time, the two ends of the rotating rod 233 respectively pass through the two support blocks 232 and are fixedly installed with rotating gears 236. On the top of the fixing frame 228, there are symmetrically installed L-shaped frames 237. On one side of the L-shaped frame 237, there is a fixedly installed rack 238. At the same time, the rotating gear 236 is meshed with the rack 238.

[0055] Embodiment 2: As Figures 3 - 4 and Figure 7 shown, when fixing the plate, the two fixing frames 228 approach each other so that the positioning plate 230 fits with the plate. The movement of the fixing frame 228 causes the positioning plate 230 to move, driving the movable rod 229 to slide on the fixing frame 228 and deforming the return spring 231. During the movement of the positioning plate 230, it can drive the rotating rod 233 to move. Through the meshing of the rotating gear 236 and the rack 238, the rotating rod 233 can be driven to rotate. After the rotating rod 233 rotates, it drives the roller shaft 235 between the rotating frames 234 to rotate downward, so that the roller shaft 235 fits with the top of the plate, enabling the positioning plate 230 to position the top of the plate while fixing the plate, preventing the plate from warping and improving the fixing effect of the plate.

[0056] The spraying assembly 3 is arranged on the top of the workbench 1 and on one side of the lower mold 101;

[0057] The spraying assembly 3 includes a first U-shaped frame 301 fixedly installed on the top of the workbench 1 and on one side of the lower mold 101. Below the inner side of the first U-shaped frame 301 on the top of the workbench 1, there is a fixedly installed second U-shaped frame 302. Inside both the first U-shaped frame 301 and the second U-shaped frame 302, there are symmetrically sliding connections with two groups of sliding rods 304. One end of each of the two groups of sliding rods 304 is fixedly installed with two support plates 303. On the outer side of the sliding rod 304, there is a tension spring 305 sleeved. The two ends of the upper tension spring 305 are fixedly connected to the sliding rod 304 and the first U-shaped frame 301 respectively. The two ends of the lower tension spring 305 are fixedly connected to the sliding rod 304 and the second U-shaped frame 302 respectively. At the same time, a shunt pipe 306 is fixedly installed between the upper and lower support plates 303. On one side of the shunt pipe 306, there is a connecting pipe 307 connected through penetration;

[0058] On one side where the two flow dividers 306 are close to each other, telescopic tubes 308 are symmetrically penetrated and opened, and a spray head is penetrated and connected to one end of the telescopic tube 308 away from the flow divider 306. A reciprocating lead screw 309 is rotatably connected on one side of the flow divider 306 between the two support plates 303. Two groups of limit blocks 310 are symmetrically installed on the outer part of the reciprocating lead screw 309. At the same time, rollers 311 are fixedly installed at both ends of the reciprocating lead screw 309 passing through the two support plates 303. Moreover, movable blocks 312 are symmetrically threadedly connected between the two groups of limit blocks 310 on the outer part of the reciprocating lead screw 309. A positioning rod 313 is slidably connected to one side inside the movable block 312, and both ends of the positioning rod 313 are fixedly connected to the two support plates 303 respectively.

[0059] Embodiment 3: As Figure 1 and Figures 8 - 9 shown, after the sheet is fixed and during conveying and feeding, it can drive through between the two support plates 303. The two rollers 311 are in contact with each other, and the tension spring 305 is in a stretched state. The top height of the lower roller 311 is slightly higher than the top surface height of the positioning plate 230. When the sheet moves through the two rollers 311, it can push the two support plates 303 away from each other, so as to drive the sliding rod 304 to move and make the tension spring 305 continue to stretch. When the sheet passes through the support plate 303, the roller 311 is in contact with the sheet. The lubricant is introduced into the connecting pipe 307 through an external pump body, so that the two flow dividers 306 can be filled with the lubricant. The lubricant can be atomized and sprayed on the sheet through the spray head on the telescopic tube 308, reducing the friction between the sheet and the die during the stamping process. And when the sheet is conveyed and moves, it drives the roller 311 to rotate, so that the reciprocating lead screw 309 can be driven to rotate. After the reciprocating lead screw 309 rotates, it can drive the movable block 312 to move reciprocally. By the movement of the movable block 312, the spray head can be driven to move reciprocally, so that the spraying range of the lubricant can be expanded during the conveying and feeding process of the sheet, facilitating the subsequent stamping work of the sheet and improving the practicability.

[0060] Working principle: When using the fixing mechanism for stamping processing of the sheet of the logistics cargo box, first, according to Figures 1 - 9As shown, when stamping the side plate of the material box, the handwheel 223 can be rotated according to the size of the plate to drive the first screw rod 214 to rotate. While the first screw rod 214 is rotating, the operator synchronously rotates the knob 224. After the first screw rod 214 rotates, it can drive the movable plate 215 to move, so that the distance between the two fixing frames 228 can be adjusted. The thread helix directions of the first screw rod 214 and the second screw rod 218 are opposite and the helix pitch is the same. After the movable plate 215 moves, the movable seat 219 moves in the opposite direction. And there is a clearance fit between the column block 221 and the guide frame 222, so that the column block 221 can remain in its original position after the fixed plate 212 moves. When stamping the plate, place the plate on the two fixing frames 228, and then start the driving motor 203 to drive the threaded rod 202 to rotate, so that the movable frame 206 can be driven to move. While the movable frame 206 is moving, it slides on the support rod 205. The movement of the movable frame 206 can drive the two connecting frames 207 to move. After the connecting frames 207 move, the moving frame 208 can be driven to move through the cross bar 209, so that the fixed plate 212 can be driven to move, and the column block 221 slides in the guide frame 222. When the column block 221 moves in the inclined section of the guide frame 222, it can drive the fixed plate 212 to move, so that the fixing frame 228 can be driven to move. After the two fixing frames 228 approach each other, the plate can be clamped and positioned. When the movable frame 206 continues to move later, the column block 221 moves to the straight section of the guide frame 222, and the plate is driven by the movable frame 206 to move above the lower die 101. Then the plate can be stamped through the stamping setting. The plate is formed by the clamping of the upper die and the lower die 101. When stamping the plate, it drives the plate to move downward, so that the fixing frame 228 can be driven to move downward, and the moving plate 226 slides on the fixed rod 225 and stretches the telescopic spring 227. When the plate is stamped and formed, the telescopic spring 227 can restore its deformation, so that the fixing frame 228 can be driven to rise and reset, and the plate can be quickly demolded. Then the driving motor 203 drives the threaded rod 202 to rotate in the reverse direction, so that the stamped plate can be unloaded. And when the fixing frame 228 moves, the column block 221 moves to the inclined section of the guide frame 222 and can automatically release the plate, which is convenient for removing the plate;

[0061] When fixing the sheet material, the two fixing brackets 228 approach each other so that the positioning plate 230 fits against the sheet material. The movement of the fixing bracket 228 causes the positioning plate 230 to move, driving the movable rod 229 to slide on the fixing bracket 228 and deforming the return spring 231. During the movement of the positioning plate 230, the rotating rod 233 can be driven to move. Through the engagement of the rotating gear 236 and the rack 238, the rotating rod 233 can be driven to rotate. After the rotating rod 233 rotates, the roller 235 between the rotating brackets 234 rotates downward, so that the roller 235 fits against the top of the sheet material, enabling the positioning plate 230 to position the top of the sheet material while fixing the sheet material, preventing the sheet material from warping and improving the fixing effect of the sheet material. After the sheet material is fixed and during conveying and loading, it can be driven to pass between the two support plates 303. The two rollers 311 are in contact with each other, and the tension spring 305 is in a stretched state. The top height of the lower roller 311 is slightly higher than the top surface height of the positioning plate 230. When the sheet material moves through the two rollers 311, the two support plates 303 can be pushed away from each other, driving the sliding rod 304 to move and further stretching the tension spring 305. When the sheet material passes through the support plates 303, the rollers 311 are in contact with the sheet material. By using an external pump body to introduce lubricant into the connecting pipe 307, the two shunt pipes 306 can be filled with lubricant, and the lubricant can be atomized and sprayed on the sheet material through the nozzles on the telescopic pipe 308, reducing the friction between the sheet material and the mold during the stamping process. Moreover, when the sheet material is conveyed and moves, it drives the rollers 311 to rotate, which can drive the reciprocating lead screw 309 to rotate. After the reciprocating lead screw 309 rotates, the movable block 312 can be driven to move reciprocally. By the movement of the movable block 312, the nozzle can be driven to move reciprocally, so that the spraying range of the lubricant can be expanded during the conveying and loading process of the sheet material, facilitating the subsequent stamping work of the sheet material and improving the practicability.
