Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically a new type of sheet metal mold leveling equipment. Background Technology

[0002] In modern industrial production, sheet metal parts are widely used in various industries, such as automotive, aerospace, and electronics. These applications require sheet metal parts to have a high degree of precision and consistency, especially in terms of shape and size. To achieve such high standards, a leveling process is essential. Leveling refers to eliminating warping and deformation problems caused by shearing, stamping, and other processes during the production of sheet metal parts by applying pressure, ensuring that their surface is flat.

[0003] A major problem with existing technology is that when processing complex-shaped or large-area frame sheet metal parts, traditional leveling equipment can usually only apply pressure from the vertical direction, ignoring the need for pressure from both sides and multiple points. This single-direction pressure application often results in warping or deformation of the sheet metal parts in other unstressed directions, especially for sheet metal parts with complex geometries and structures. For example, when pressure is applied only from above, the sides and bottom of the sheet metal parts may not be sufficiently leveled, and vice versa. In addition, for some high-precision applications, single-direction pressure application is not only inefficient, but also prone to local over- or under-pressure, thus affecting the quality of the final product. Therefore, there is an urgent need for a new type of leveling equipment that can apply pressure from multiple points in the vertical direction and both sides to improve leveling effect and production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of sheet metal mold leveling equipment to solve the problems mentioned in the background art, such as incomplete leveling, low efficiency, and local over- or under-pressing caused by the fact that traditional leveling equipment can only apply pressure from the vertical direction when processing complex shapes or large-area frame sheet metal parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel sheet metal mold leveling device, comprising a base, a worktable driven by an annular guide rail at the center of the top of the base, horizontally distributed top plates at the top of the frame on both sides of the base, a hydraulic cylinder at the center of the top of the top plate, a lifting circular plate driven by the hydraulic cylinder at the bottom of the top plate, a plurality of adjustable movable arms surrounding the lifting circular plate, vertical pressure blocks installed at the bottom of the movable arms, and vertical plates driven by linear guide rails on both sides of the base located on the worktable, a U-shaped frame on the corresponding side of the vertical plate, a rotating roller driven by a servo motor inside the U-shaped frame, and a plurality of lateral pressure blocks installed on the outer side of the rotating roller.

[0006] Preferably, a plurality of side studs are uniformly fixed on the outer side of the rotating roller, and the rear ends of the lateral pressure blocks are all sleeved on the outside of the side studs through a threaded structure.

[0007] Preferably, four rectangular notches are evenly arranged around the lifting plate, and the inner ends of the movable arms are all connected to the inner walls of the rectangular notches of the lifting plate through hinges. Furthermore, a push cylinder is connected between the top inner wall of the rectangular notches of the lifting plate and the top of the movable arm.

[0008] Preferably, a top stud is fixed at the bottom of the movable arm, and the inner end of the vertical pressure block is sleeved on the outside of the top stud through a threaded structure.

[0009] Preferably, a magnetic block is fixed on the inner wall of the outer end of the rectangular notch of the lifting circular plate, and the top of the outer end of the movable arm is provided with a mating interface that cooperates with the structure of the magnetic block.

[0010] Preferably, the U-shaped frame and rotating rollers are symmetrically arranged in two sets on the outer side of the vertical plate, and the lateral pressure blocks are evenly arranged in three on the outer side of each rotating roller.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: this novel sheet metal mold leveling equipment can apply uniform pressure to sheet metal parts simultaneously from the vertical direction and both sides, effectively eliminating warping and deformation in all directions, thereby effectively improving the leveling quality and consistency of sheet metal parts. The equipment uses a hydraulic cylinder to drive a lifting circular plate and vertical pressure blocks mounted on the movable arm, combined with a U-shaped frame and rotating rollers on the side support plate and lateral pressure blocks on their outer sides, to achieve precise pressure application at multiple points and in multiple directions. This not only improves the ability to handle complex-shaped sheet metal parts but also solves the problems of low efficiency and uneven local pressure caused by traditional equipment when applying pressure in a single direction.

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: a novel sheet metal mold leveling device, including a base 1, a worktable 2 driven by a ring guide rail at the center of the top of the base 1, a plurality of mounting holes for installing sheet metal fixtures on the worktable 2, horizontally distributed top plates 3 at the top of the frame on both sides of the base 1, a hydraulic cylinder 4 fixed by bolts at the center of the top of the top of the top plate 3, a lifting circular plate 5 driven by the hydraulic cylinder 4 at the bottom of the top plate 3, the output end of the hydraulic cylinder 4 being fixedly connected to the center of the top of the lifting circular plate 5, a plurality of adjustable movable arms 6 surrounding the lifting circular plate 5, a vertical pressure block 7 installed at the bottom of the movable arms 6, and side support plates 8 driven by linear guide rails on both sides of the base 1 located on the worktable 2, with the corresponding side of the side support plates 8 welded and fixed. The worktable 2 has a U-shaped frame 9. Inside the U-shaped frame 9, a rotating roller 10 is driven by a servo motor. The upper and lower ends of the rotating roller 10 are connected to the inner walls of the upper and lower ends of the U-shaped frame 9 through bearings. Several lateral pressure blocks 11 are installed on the outer side of the rotating roller 10. In this structure, the worktable 2 rotates to a suitable angle on the annular guide rail on the base 1 to accurately position the sheet metal part. Then, the hydraulic cylinder 4 drives the lifting circular plate 5 to rise and fall on the top plate 3. The movable arm 6 adjusts its position according to the shape of the sheet metal part to drive the vertical pressure block 7 to apply the necessary vertical pressure to the sheet metal part. At the same time, the side support plate 8 moves through the linear guide rail and causes the rotating roller 10 to rotate to a suitable orientation angle inside the U-shaped frame 9 under the drive of the servo motor, so as to drive the multiple lateral pressure blocks 11 to apply pressure to the sheet metal part. Precise pressure is applied from the sides, allowing the operator to flexibly adjust the number of vertical pressure blocks 7 and lateral pressure blocks 11 as needed. This ensures optimal pressure distribution for sheet metal parts of different sizes and complexities, avoiding material damage caused by excessive pressure and preventing the inability to completely eliminate warping or deformation due to insufficient pressure. This equipment not only solves the limitations of unidirectional pressure application in traditional leveling technology but also improves the efficiency and quality of processing complex-shaped frame sheet metal parts, meeting the needs of high-precision applications and significantly improving overall production efficiency and product quality. Several side studs 12 are evenly fixed on the outer side of the rotating roller 10, and the rear ends of the lateral pressure blocks 11 are all threaded onto the outer side of the side studs 12. In this structure, each lateral pressure block 11 can be finely adjusted to different positions along the outside of the side stud 12 as needed, and the lateral pressure blocks 11 are also easy to disassemble to adjust the appropriate number. This allows the operator to flexibly adjust the position and number of the lateral pressure blocks 11 according to the specific shape and size of the sheet metal parts, ensuring more precise and effective pressure applied to the sheet metal parts, greatly enhancing the operational flexibility and practicality of the equipment. Four rectangular notches are evenly arranged around the lifting circular plate 5, and the inner ends of the movable arms 6 are all connected to the inner walls of the rectangular notches of the lifting circular plate 5 via hinges. A push cylinder 13 is connected between the top inner wall of the rectangular notches of the lifting circular plate 5 and the top of the movable arms 6. The push cylinder 13 is an existing tilting swing cylinder.The MHC2-16D-75 model, suitable for precision adjustment applications, can be used. Both ends of the push cylinder 13 are connected by dedicated spherical bearings to ensure stability and flexibility. This structure allows the push cylinder 13 to adjust the angle of the movable arm 6 relative to the lifting disc 5 via extension and retraction. This enables the vertical pressure block 7 mounted at its bottom to precisely apply vertical pressure to different parts of the sheet metal workpiece. This not only allows the equipment to adapt to sheet metal workpieces of different shapes and sizes but also ensures that the vertical pressure block 7 contacts the workpiece surface at the optimal angle during leveling, providing the best... Effective pressure distribution avoids pressure dispersion or concentration problems caused by improper angles, ensuring high efficiency and consistency in leveling operations. This greatly enhances the equipment's ability to handle complex-shaped sheet metal parts, improving overall production efficiency and product quality. A top stud 14 is welded and fixed to the bottom of the movable arm 6, and the inner end of the vertical pressure block 7 is threaded onto the outside of the top stud 14. This structure allows the vertical pressure block 7 to be precisely adjusted relative to the top stud 14 by rotation, enabling the operator to fine-tune the height of the vertical pressure block 7 according to the specific shape and thickness of the sheet metal part. To further ensure uniform and moderate applied pressure, a magnetic block 15 is adhered and fixed to the inner wall of the outer end of the rectangular notch of the lifting disc 5. A mating interface that mates with the magnetic block 15 is welded and fixed to the top of the outer end of the movable arm 6. When the movable arm 6 does not need angle adjustment and is retracted to a horizontal position, the movable arm 6 is tightly fitted with the magnetic block 15 through its top mating interface, achieving a stable fixation. This ensures that the movable arm 6 can stably remain in a horizontal position when not in operation, preventing accidental swinging or damage due to equipment movement or other external factors. Furthermore, during maintenance or adjustment... During operation, the operator can easily detach the movable arm 6 from the magnetic block 15 for convenient and quick necessary operations. Two sets of U-shaped frames 9 and rotating rollers 10 are symmetrically arranged on the outer side of the side support plate 8, and three lateral pressure blocks 11 are evenly distributed on the outer side of each rotating roller 10. This structure, driven by a servo motor, rotates the rotating roller 10, causing the three lateral pressure blocks 11 to move synchronously, thereby achieving uniform pressure on the side of the sheet metal part. Furthermore, the three lateral pressure blocks 11 on each set of rotating rollers 10 can be flexibly adjusted in position according to the specific shape and size of the sheet metal part to accommodate different specifications.

[0019] Working Principle: When using this new sheet metal mold leveling equipment, the sheet metal part to be processed is first placed on the worktable 2, and the sheet metal fixture is fixed using several mounting holes on it. Then, the worktable 2 is rotated to a suitable angle via the annular guide rail on the base 1 to accurately position the sheet metal part. Next, the hydraulic cylinder 4 in the middle of the top plate 3 is activated, driving the lifting circular plate 5 to descend to the appropriate position. At this time, the movable arm 6 adjusts its angle according to the specific shape and size of the sheet metal part. The angle of the movable arm 6 relative to the lifting circular plate 5 is controlled by pushing the cylinder 13, so that the vertical pressure block 7 installed at the bottom can accurately align with different parts of the sheet metal part to prepare to apply vertical pressure. At the same time, the side support plate 8 moves along the linear guide rail to the designated position and is driven by the servo motor to the U-shaped frame 9. The rotating roller 10 rotates, adjusting the three lateral pressure blocks 11 evenly distributed on the outer side of each rotating roller 10 to a suitable orientation angle, providing precise pressure application to the side of the sheet metal part. If it is necessary to adjust the number or position of the lateral pressure blocks 11, fine adjustment can be made along the side studs 12 by loosening the threaded structure to ensure the best pressure distribution effect. Then, the hydraulic cylinder 4 further drives the lifting circular plate 5 to press down, while the lateral pressure blocks 11 begin to apply lateral pressure to the sheet metal part under the drive of the servo motor. The vertical pressure block 7 applies vertical pressure downward. After the operation is completed, the hydraulic cylinder 4 retracts, the lifting circular plate 5 rises, and the movable arm 6 is retracted to a horizontal state and tightly attached to the magnetic block 15 through the top welded interface, and is stably held in a horizontal position, thus completing a series of operations.
