Description

Technical Field

[0001] This utility model relates to the field of hopper processing technology, specifically to a hopper processing device for grain machinery. Background Technology

[0002] Hopper processing equipment in grain machinery is typically used to manufacture and process hoppers for grain storage and transportation. During hopper production, sheet metal needs to be bent. However, traditional sheet metal bending equipment operates with a relatively rigid method, posing certain safety hazards. Furthermore, the bending dies in traditional equipment are mostly fixed in position, and their relative positions cannot be changed. This severely limits the production capabilities of traditional equipment when manufacturing hoppers of different sizes.

[0003] Existing technology, such as publication number CN112916663A, provides a sheet metal bending device for flexible hopper production, belonging to the technical field of sheet metal processing equipment. This sheet metal bending device for flexible hopper production includes a bending worktable, a loading plate, a brake cylinder, a bending punch, and a servo motor. The top of the bending worktable is equipped with two bidirectional adjusting threaded rods. Because the inner top of the sheet metal limiting frame is fixedly connected with an anti-collision layer made of sponge, which has excellent softness and easily returns to its original shape, it provides good protection for both the sheet metal itself and the sheet metal limiting frame during the bending process. Simultaneously, the inner bottom of the sheet metal limiting frame is equipped with multiple moving rollers, both ends of which are rotatably connected to the sheet metal limiting frame via rotating shafts. This facilitates the movement of the sheet metal's ends during bending. Compared with traditional equipment, this equipment is gentler and safer during the sheet metal bending process.

[0004] In this design, two bending dies are connected to the outer surfaces of two opposing threaded sections of two bidirectional adjusting threaded rods via adjusting sleeves. This causes the two bending dies to move in opposite directions, changing their relative positions and thus altering the equipment's production conditions. This allows for the processing of plates of different sizes. However, in practical use, since the die's area is fixed, simply changing its position cannot alter its actual support area. This results in insufficient support during bending, potentially leading to uncontrollable deformation. Therefore, we propose a grain machinery hopper processing device. Utility Model Content

[0005] The purpose of this utility model is to provide a grain machinery hopper processing device, which solves the problem that the bending molds of sheet metal bending equipment are mostly fixed in position and the relative position of the molds cannot be changed, which makes the equipment limited in producing hoppers of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grain processing equipment hopper includes a worktable, a lifting platform slidably connected to the inner wall of the worktable, an upper pressing mold provided on the top of the lifting platform, and a support assembly provided above the worktable for supporting the upper pressing mold.

[0008] The top of the lifting platform has densely arranged circular holes, and the inner walls of the circular holes are slidably connected to adaptive top rods. The bottom of the lifting platform is fixedly connected to an air cylinder, which is connected to the interior of the lifting platform. The inner wall of the air cylinder is slidably connected to a piston plate.

[0009] Preferably, a horizontal plate is fixedly connected to the bottom of the workbench, and a cylinder is fixedly connected to the top of the horizontal plate, with the cylinder being fixedly connected to the bottom of the piston plate.

[0010] Preferably, a return spring is fixedly connected between the inner wall of the air cylinder and the top of the piston plate, and a vent plate is fixedly connected to the bottom of the lifting platform inside the air cylinder.

[0011] Preferably, the support assembly includes a support base, which is fixedly connected to the workbench. A support shaft is fixedly connected to the top of the support base, and a hinge plate is rotatably connected to the outer wall of the support shaft.

[0012] Preferably, the top of the hinge plate is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to a mounting bracket, which is fixedly connected to the upper mold by bolts.

[0013] Preferably, the number of mounting brackets is four, and a pressure ring is fixedly connected to the top of the hinge plate at the position of the slide groove.

[0014] Preferably, the two ends of the support shaft are respectively hinged with locking blocks, and the two sides of the hinge plate are respectively provided with locking slots that cooperate with the locking blocks.

[0015] By employing the above technical solution, this utility model provides a grain processing equipment hopper. It possesses at least the following beneficial effects:

[0016] I. This utility model utilizes an adaptive push rod that slides along the inner wall of a densely arranged circular hole on the top of the lifting platform. The platform is then lifted by a cylinder. When the sheet metal contacts the upper die, the lifting platform stops rising due to the contact between the sheet metal and the upper die. At this point, the continuous lifting force of the cylinder pushes the piston plate to compress the return spring, forcing gas from the air cylinder through the vent plate into the lifting platform. This causes a surge in pressure inside the lifting platform, causing the adaptive push rod to gradually extend through the circular hole and bend the sheet metal according to the outer contour of the upper die. By setting a lifting platform that adapts to the shape of the upper die, when different sizes of sheet metal need to be processed, only the upper die of the corresponding size needs to be replaced, eliminating the need to replace both the upper and lower modules simultaneously. This reduces the material cost and replacement time required for die replacement and avoids the problem of uncontrollable deformation caused by the lack of die support in the comparative scheme.

[0017] II. This utility model installs the upper pressing mold at the bottom of the mounting frame to facilitate support of the upper pressing mold. Furthermore, the support range of the mounting frame can be adjusted by adjusting the length of the mounting frame extending out of the slide groove, thereby improving the stability of supporting upper pressing molds of different sizes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A grain processing machine with a hopper, such as Figure 1 - Figure 4 As shown, the system includes a workbench 1, a lifting platform 2 slidably connected to the inner wall of the workbench 1, an upper pressure mold 3 on the top of the lifting platform 2, a support assembly 4 above the workbench 1 for supporting the upper pressure mold 3, a densely arranged circular hole 21 on the top of the lifting platform 2, and adaptive push rods 22 slidably connected to the inner wall of each circular hole 21, an air cylinder 25 fixedly connected to the bottom of the lifting platform 2, and the air cylinder 25 communicating with the interior of the lifting platform 2, a piston plate 26 slidably connected to the inner wall of the air cylinder 25, a horizontal plate 29 fixedly connected to the bottom of the workbench 1, a cylinder 28 fixedly connected to the top of the horizontal plate 29, and the cylinder 28 fixedly connected to the bottom of the piston plate 26, a return spring 27 fixedly connected between the inner wall of the air cylinder 25 and the top of the piston plate 26, and a vent plate 24 fixedly connected to the bottom of the lifting platform 2 inside the air cylinder 25.

[0026] In this embodiment, by sliding adaptive push rods 22 on the inner wall of the densely arranged circular holes 21 on the top of the lifting platform 2, the lifting platform 2 is lifted by the cylinder 28. When the plate comes into contact with the upper pressure mold 3, the lifting platform 2 stops rising because it is pressed against the plate and the upper pressure mold 3. At this time, the force of the cylinder 28 continuously lifting will push the piston plate 26 to compress the return spring 27, and squeeze the gas in the air cylinder 25 from the vent plate 24 into the interior of the lifting platform 2, causing the pressure inside the lifting platform 2 to surge. This causes the adaptive push rods 22 to gradually extend out of the circular holes 21 and bend the plate according to the outer contour of the upper pressure mold 3. By setting the lifting platform 2 to adapt to the shape of the upper pressure mold 3 and cooperate with the upper pressure mold 3, when different sizes of plates need to be processed, only the upper pressure mold 3 of the corresponding size needs to be replaced. There is no need to replace the upper and lower modules at the same time, thereby reducing the material cost and replacement time required for mold replacement.

[0027] like Figure 4As shown, preferably, the support assembly 4 includes a support base 41, which is fixedly connected to the workbench 1. A support shaft 42 is fixedly connected to the top of the support base 41. A hinge plate 43 is rotatably connected to the outer wall of the support shaft 42. A slide groove 44 is provided on the top of the hinge plate 43. A mounting bracket 45 is slidably connected to the inner wall of the slide groove 44. The mounting bracket 45 is fixedly connected to the upper mold 3 by bolts. There are four sets of mounting brackets 45. A pressure ring 46 is fixedly connected to the top of the hinge plate 43 at the position of the slide groove 44, which can improve the stability of the mounting bracket 45 inside the slide groove 44.

[0028] In this embodiment, the upper pressing mold 3 is installed at the bottom of the mounting bracket 45 to facilitate support of the upper pressing mold 3. The support range of the mounting bracket 45 can be adjusted by adjusting the length of the mounting bracket 45 extending out of the slide groove 44, thereby improving the stability of supporting upper pressing molds 3 of different sizes.

[0029] like Figure 4 As shown, preferably, the two ends of the support shaft 42 are respectively hinged to the locking blocks 431, and the two sides of the hinge plate 43 are respectively provided with locking grooves 421 that cooperate with the locking blocks 431 at the corresponding positions.

[0030] In this embodiment, after the plate is placed on the top of the workbench 1, the hinge plate 43 is rotated horizontally so that the upper pressure mold 3 is above the plate. Then, the locking block 431 is pushed into the corresponding slot 421 for fixing, so as to ensure the stability of the upper pressure mold 3 during the processing and to ensure the quality of bending.

[0031] In use, the hopper processing equipment of this utility model is equipped with an upper pressing mold 3 installed at the bottom of a mounting frame 45 for easy support. The support range of the mounting frame 45 can be adjusted by changing the length of the extension of the mounting frame 45 over the slide groove 44, thereby improving the stability of supporting upper pressing molds 3 of different sizes. After placing the plate on top of the workbench 1, the hinge plate 43 is rotated horizontally so that the upper pressing mold 3 is above the plate. Then, the locking block 431 is pushed into the corresponding slot 421 for fixation, ensuring... To ensure the stability of the upper die 3 during processing and guarantee the bending quality, the lifting platform 2 is raised by the cylinder 28. When the sheet metal comes into contact with the upper die 3, the lifting platform 2 stops rising because it is pressed against the upper die 3. At this time, the force of the cylinder 28 continuously lifting will push the piston plate 26 to compress the return spring 27 and squeeze the gas in the air cylinder 25 from the vent plate 24 into the interior of the lifting platform 2, causing the pressure inside the lifting platform 2 to surge. This causes the adaptive push rod 22 to gradually extend out of the round hole 21 and bend the sheet metal according to the outer contour of the upper die 3.
