Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] like Figure 1-Figure 2 As shown, the present application provides a composite intermediate bulk container steel frame stamping mechanism, comprising a workbench 1, and a clamping mechanism 3 installed at the center of the workbench 1, the clamping mechanism 3 is used to limit and clamp the bottom cross beam of the frame;

[0027] The clamping mechanism 3 includes four groups of limiting parts, which are respectively arranged at the inner sides of the edges of the working table 1. The limiting parts include a first seat 33 and a limiting seat 31 slidably mounted on the first seat 33. The limiting seat 31 is suitable for sliding on the first seat 33, and a second cylinder (not shown in the figure) is fixed on one side of the first seat 33. The output end of the second cylinder is fixedly connected to the limiting seat 31, so that the limiting seat 31 is suitable for moving on the first seat 33 under the drive of the second cylinder.

[0028] Side columns 32 are provided on both sides of the limiting seat 31, and a placement groove 321 corresponding to the bottom cross beam of the frame is opened on the side column 32, and a fork structure is formed on the side column 32, and a penetrating limiting groove 322 is opened on the two side walls of the side column 32 at the placement groove 321, and a bolt (not marked in the figure) is passed through the limiting groove 322, and the bolt is suitable for moving up and down along the limiting groove 322, and a nut is threadedly connected on the bolt to fix the position of the bolt by the nut, and when the bottom cross beam of the frame is in the placement groove 321, the bottom cross beam of the frame is limited and fixed by the cooperation of the bolt and the nut;

[0029] like Figure 2-Figure 3 As shown, the clamping mechanism 3 also includes a tensioning unit 4, which is provided with four groups, and every two groups of tensioning units 4 are diagonally arranged, and the four groups of tensioning units 4 are located between every two groups of limiting parts. The tensioning unit 4 includes a second seat 44, and a stamping seat 41 slidably mounted on the second seat 44. A third cylinder (not marked in the figure) is installed on the side of the second seat 44, and the third cylinder is used to drive the stamping seat 41 to move along the second seat 44;

[0030] Two groups of symmetrically arranged receiving grooves 411 and a slide groove 412 at the bottom of the receiving groove 411 are provided on the punching seat 41. A top block 42 is slidably installed in the receiving groove 411. The top block 42 is suitable for extending toward the top of the punching seat 41 or contracting toward the receiving groove 411. At the same time, a shaft rod 421 adapted to the slide groove 412 is fixed at the bottom of the top block 42, and the shaft rod 421 is always in the slide groove 412, and the shaft rod 421 is used to limit the extension or contraction of the top block 42.

[0031] A second spring 43 is sleeved on the shaft 421, and the second spring 43 pushes the top block 42 out of the receiving groove 411, so that the top block 42 always extends out of the top of the punching seat 41. When the top block 42 is subjected to an external force, the top block 42 shrinks toward the receiving groove 411 and squeezes the second spring 43 to shrink it. After the external force on the top block 42 disappears, the top block 42 is pushed out of the receiving groove 411 under the action of the second spring 43.

[0032] When the bottom cross beam of the frame needs to be fixed, the second cylinder is used to adjust the limit seat 31 so that the spacing between the four groups of limit seats 31 matches the size of the bottom cross beam of the frame, and then the bottom cross beam of the frame is installed in the placement groove 321 of the side column 32, and the bottom cross beam of the frame is fixed in the placement groove 321 by the cooperation of bolts and nuts;

[0033] Then the third cylinder drives the punching seat 41 to move, so that the punching seat 41 approaches the corner of the frame bottom beam, and the top block 42 on the punching seat 41 contacts the corner of the frame bottom beam, so as to tighten and limit the corner position of the frame bottom beam, and achieve the purpose of limiting and fixing the frame bottom beams of different sizes;

[0034] like Figure 1-Figure 2 As shown, a stamping part 2 is provided at each of the four corners of the workbench 1. The stamping part 2 is provided near the tensioning unit 4. The stamping part 2 is used to perform stamping and flattening operations on the bottom cross beam of the frame on the clamping mechanism 3.

[0035] The stamping part 2 includes a frame 21 slidably mounted on the workbench 1, and the frame 21 is suitable for approaching or moving away from the stamping seat 41, and the frame 21 is connected to a screw transmission structure to drive the frame 21 to slide;

[0036] A first cylinder 22 is fixedly mounted on the frame 21, a fixing plate 23 mounted on the frame 21 is provided below the first cylinder 22, and an output end of the first cylinder 22 passes through the fixing plate 23 and is connected to a transmission plate 24, a punch 26 is fixedly mounted at the bottom of the transmission plate 24, and the punch 26 is used to punch holes in the bottom cross beam of the frame;

[0037] At the same time, a stamping plate 25 is arranged below the transmission plate 24, and a limiting rod 252 is arranged on the stamping plate 25, and the limiting rod 252 penetrates the transmission plate 24, and the stamping plate 25 and the transmission plate 24 are suitable for approaching or moving away from each other under the action of the limiting rod 252, and the punch 26 penetrates the stamping plate 25, and the punch 26 is suitable for extending toward the bottom of the stamping plate 25;

[0038] A first spring 251 is sleeved on the limiting rod 252. Under the action of the first spring 251, the stamping plate 25 is adapted to move closer to or farther from the transmission plate 24.

[0039] When it is necessary to punch the bottom cross beam of the frame, first, the screw drive structure drives the frame 21 to approach the punching seat 41. After the punch 26 of the punching part 2 moves to the bottom cross beam of the frame, the first cylinder 22 drives the transmission plate 24 to approach the punching seat 41. Under the action of the first spring 251, the transmission plate 24 drives the punching plate 25 to contact the top block 42. In the process of the punching plate 25 approaching the punching seat 41, the punching plate 25 slowly squeezes the top block 42, so that the top block 42 shrinks into the accommodating groove 411, and the top block 42 always contacts the corner of the bottom cross beam of the frame, and the punching plate 25 flattens the bottom cross beam of the frame.

[0040] At the same time, when the transmission plate 24 approaches the punching seat 41, the frame bottom beam indirectly drives the punch 26 to approach the frame bottom beam. At the same time, a punching hole (not shown in the figure) corresponding to the punch 26 is opened on the punching seat 41. The punching hole is located between the inner side of the edge of the punching seat 41 and the side of the top block 42. At the same time, the frame bottom beam is punched under the cooperation of the punch 26 and the punching hole.

[0041] Finally, after the stamping of the bottom cross beam of the frame is completed, the first cylinder 22 drives the transmission plate 24 away from the stamping seat 41, and the stamping plate 25 is reset under the action of the first spring 251. At the same time, in the process of the stamping plate 25 moving away from the stamping seat 41, the top block 42 is extended outward from the stamping seat 41 under the action of the second spring 43, and the part of the top block 42 that contacts the corner of the bottom cross beam of the frame is made of silicone material, so as to prevent the top block 42 from damaging the bottom cross beam of the stamped frame during the process of extending outward from the stamping seat 41.

[0042] To summarize, under the action of the second cylinder, the limit seat 31 is driven to move, and with the cooperation of the bolts and nuts, the bottom beam of the frame is limited, and through the action of the third cylinder, the stamping seat 41 is moved, and with the cooperation of the top block 42, the corner of the bottom beam of the frame is limited and fixed, thereby achieving the effect of limiting and fixing the bottom beams of the frame of different sizes. At the same time, with the cooperation of the top block 42 and the second spring 43, the top block 42 is suitable for contracting or extending toward the stamping seat 41, and the top block 42 always conflicts with the corner of the bottom beam of the frame, thereby preventing the frame bottom beam from offset during stamping.

[0043] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
