Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts processing, and in particular to an online combined edge-cutting device. Background Technology

[0002] With the development of automotive parts manufacturing technology, the structural complexity of modern automotive parts is also increasing. The cross-sectional shapes and profiles of roll-formed materials are becoming more complex, which presents challenges to processing and manufacturing. For example... Figure 1 The product shown undergoes a rolling process where the edges of the profile are rolled to increase rigidity, followed by edge trimming and cutting in certain areas to achieve the desired shape. Traditional processing involves simple online blanking, where a batch of profiles is trimmed uniformly before being transferred to the next station. This requires multiple offline processes to complete the cutting of complex cross-sections and obtain the desired finished product. This method is cumbersome and inefficient. Given these problems, a device is urgently needed to meet the needs of actual production processing. Utility Model Content

[0003] This invention provides an online combined edge stripping and cutting device, which can complete the two processes of edge stripping and end face cutting in one machine, effectively solving the problems of numerous processes and low efficiency in traditional technology.

[0004] This utility model solves the above-mentioned technical problems through the following technical solutions.

[0005] An online combined edge stripping and cutting device includes an edge stripping system, a cutting mechanism, and a frame. An edge stripping station and a cutting station are arranged horizontally on the frame. The edge stripping system and the cutting mechanism are arranged sequentially on the edge stripping station and the cutting station according to the length of the workpiece. A support roller is provided on the frame. The profile to be processed passes over the support roller and moves from the edge stripping station to the cutting station. After the support roller delivers the profile to the edge stripping station for edge stripping, it enters the cutting station for cutting.

[0006] The edge-trimming system includes two sets of edge-trimming mechanisms arranged symmetrically on the left and right. Each set of edge-trimming mechanisms includes a stationary edge-trimming blade, a moving edge-trimming blade, and a lifting cylinder. The stationary edge-trimming blade is obliquely fixed above the frame, and its setting angle matches the curling angle of the profile. The moving edge-trimming blade is matched with the stationary blade. The lifting cylinder drives the moving edge-trimming blade to move obliquely back and forth, and the curling edge of the profile passes between the stationary edge-trimming blade and the moving edge-trimming blade.

[0007] The above-mentioned online combined edge-cutting device is also equipped with a lifting mechanism. The lifting mechanism includes a guide assembly, a lifting plate, a pull-back cylinder, and a lifting spring. The roller is set on the lifting plate. The pull-back cylinder and the lifting spring are set at the bottom of the lifting plate. The two ends of the lifting spring are respectively connected to the frame and the bottom of the lifting plate. The cylinder seat of the pull-back cylinder is fixed on the frame, and the cylinder rod is connected to the lifting plate, driving the lifting plate to move up and down.

[0008] The above-mentioned online combined edge-cutting device is also equipped with a guide assembly, which includes a guide column and a guide block. One side of the lifting plate is fixedly connected to the guide block. The guide column is longitudinally arranged on the frame, and the guide block moves longitudinally along the guide column.

[0009] The aforementioned online combined edge-trimming and cutting device also includes several limiting posts. The bottom end of each limiting post is fixed to the frame. The lifting plate has limiting holes that match the positions of the limiting holes and the top of each limiting post passes through the limiting holes. A baffle is provided at the top of each limiting post. A lifting spring is sleeved on the limiting post, and the lifting spring pushes the lifting plate against the bottom surface of the baffle. The height of the baffle is higher than the working height of the cutting station, and the position of the baffle avoids the location of the profile conveyor.

[0010] The above-mentioned online combined edge-trimming and cutting device is provided with pressure rollers and limiting rollers on both sides of the edge-trimming stationary blade. The bottom end of the pressure roller is flush with the edge-trimming stationary blade. The limiting rollers are arranged in pairs on the lifting plate. The profile passes through the middle of the limiting rollers, and the limiting rollers abut against the two sides of the profile.

[0011] The above-mentioned online combined edge-cutting device includes a cutting tool, a liftable pressure block, and a cutting cylinder. The pressure block is located next to the cutting tool, and an actuation cylinder is installed on the pressure block to drive the pressure block to rise and fall. The cutting tool includes a moving cutting blade and a stationary cutting blade. The bottom surface of the pressure block is provided with a pressing groove that matches the processed profile. The stationary cutting blade is fixed at the cutting station, and the cutting cylinder is fixed above the stationary cutting blade. The cutting cylinder drives the moving cutting blade to move toward the stationary cutting blade.

[0012] Compared with existing technologies, this invention enables rapid online cutting and forming of profiles with complex cross-sections, combining the edge trimming and end-face cutting processes to effectively improve production efficiency and reduce production costs. The lifting plate, which can be raised and lowered in conjunction with the edge trimming stationary blade, prevents the profile to be processed from contacting the edge trimming stationary blade and its components during transport, thereby reducing wear on the blades. This invention features a compact structure, high efficiency, and ensures the consistency and stability of the end-face cutting, thus improving product quality. Attached Figure Description

Pressing groove. Detailed Implementation

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model.

[0027] like Figures 1 to 8This utility model includes a stripping system, a cutting mechanism, and a frame 1. A stripping station 2 and a cutting station 3 are arranged horizontally on the frame 1. The stripping system and the cutting mechanism are respectively arranged on the stripping station 2 and the cutting station 3 according to the length of the finished part. A support roller 4 is provided on the frame 1. The profile to be processed passes over the support roller 4, and the profile moves from the stripping station 2 to the cutting station 3. After the profile reaches its position, it is stripped at the stripping station 2, and then continues to move to the cutting station 3, where the cutting mechanism is activated. This allows for the stripping and cutting processes to be completed in one processing device, saving the disadvantages of transferring between multiple processes.

[0028] The edge-trimming system includes two sets of edge-trimming mechanisms symmetrically arranged on the left and right. Each set of edge-trimming mechanisms includes a stationary edge-trimming blade 5, a moving edge-trimming blade 6, and a lifting cylinder 7. Since the rolled edge is obliquely positioned on the workpiece, the stationary edge-trimming blade 5 is obliquely fixed above the frame 1 to match the rolled edge angle of the profile. The moving edge-trimming blade 6 is aligned with the stationary edge-trimming blade 5. The lifting cylinder 7 drives the moving edge-trimming blade 6 to move obliquely back and forth, allowing the rolled edge of the profile to pass between the stationary edge-trimming blade 5 and the moving edge-trimming blade 6. Through the above arrangement, the profile sequentially passes through the edge-trimming station 2 and the cutting station 3. The rolled edge of the profile is located between the stationary edge-trimming blade 5 and the moving edge-trimming blade 6. The moving edge can be cut off by the action of the moving blade, completing the edge-trimming process.

[0029] A lifting mechanism is also provided, comprising a guide assembly 8, a lifting plate 9, a pull-back cylinder 10, and a lifting spring 11. The support roller 4 is mounted on the lifting plate 9. The pull-back cylinder 10 and the lifting spring 11 are located at the bottom of the lifting plate 9. The two ends of the lifting spring 11 are connected to the frame 1 and the bottom of the lifting plate 9, respectively. The cylinder seat of the pull-back cylinder 10 is fixed to the frame 1, and the cylinder rod is connected to the lifting plate 9, driving the lifting plate 9 to move up and down. After the workpiece is in position, the lifting spring 11 pushes the workpiece, lifting it to the bottom surface of the edge-cutting stationary blade 5. Then, the blade moves once to complete the edge-cutting. Afterward, the pull-back cylinder 10 retracts, pulling the lifting plate 9 back to be flush with the support roller 4. Then, the support roller 4 drives the workpiece to continue moving to the next workstation. The combined force generated by the lifting spring 11 and the pull-back cylinder 10 causes the lifting plate 9 to rise and fall, ensuring the stability of the lifting action.

[0030] To ensure that the lifting plate 9 can rise and fall along a fixed trajectory, a guide assembly 8 is also provided. The guide assembly 8 includes a guide post 12 and a guide block 13. One side of the lifting plate 9 is fixedly connected to the guide block 13. The guide assembly is longitudinally arranged on the frame 1. The guide post 12 is provided with a slot, and the guide block 13 is provided with a locking block. The locking block and the slot are connected in cooperation. The guide block 13 moves longitudinally along the guide post 12. This ensures the stability of the lifting plate 9's up and down movement, thereby ensuring that the workpiece can accurately fit the edge-trimming stationary knife 5 and ensuring the edge-trimming quality.

[0031] To limit the lifting height of the lifting spring 11 and ensure that the workpiece on the lifting plate 9 fits snugly against the edge-trimming stationary blade 5, reducing impact damage to the edge-trimming stationary blade 5, several limiting posts 14 are provided. The bottom end of each limiting post 14 is fixed to the frame 1. The lifting plate 9 has limiting holes, the positions of which match the limiting posts 14. The top of each limiting post 14 passes through the limiting holes, and a baffle 15 is provided at the top of each limiting post 14. The lifting spring 11 is sleeved on the limiting posts, and the lifting spring 11 pushes the lifting plate 9 against the bottom surface of the baffle 15. The height of the baffle 15 is higher than the working height of the cutting station 3, and the position of the baffle 15 avoids the profile conveying position. The setting height of the baffle 15 is set according to the height of the workpiece and the edge-trimming stationary blade 5. This prevents the workpiece from colliding with the edge-trimming stationary blade 5 and also ensures the stability of the workpiece's lifting height.

[0032] The edge-trimming stationary blade 5 is also equipped with pressure rollers 16 and limiting rollers 17 on both sides. The bottom end of the pressure roller 16 is flush with the edge-trimming stationary blade 5 to prevent the workpiece from impacting the stationary blade and extend its service life. The limiting rollers 17 are arranged in pairs on the lifting plate 9, and the profile passes through the middle of the limiting rollers 17, with the limiting rollers 17 abutting against the sides of the profile. This ensures stable conveying of the workpiece on the frame 1 and prevents deviation.

[0033] The cutting mechanism includes a stationary cutting blade, a moving cutting blade, a pressure block 18, and a cutting cylinder 19. The pressure block 18 is located beside the stationary cutting blade, and its bottom surface has a pressing groove 20 that matches the shape of the profile being processed. The stationary cutting blade is fixed at the cutting station 3, and the cutting cylinder 19 is fixed above the stationary cutting blade. The cutting cylinder 19 drives the moving cutting blade to move towards the stationary cutting blade, thus completing the cutting operation on the end face of the workpiece.

[0034] The working process is as follows: After the profile to be processed is in place, the support roller stops moving, and the lifting spring 11 pushes the lifting plate 9, lifting the workpiece on the lifting plate 9 until it is in contact with the bottom surface of the edge-cutting stationary knife 5. Then, the edge-cutting knife 6 cuts off the rolled edge of the profile, completing the edge-cutting. Afterwards, the pull-back cylinder 10 retracts, lowering the lifting plate 9 back to be flush with the support roller 4. Then, the support roller 4 drives the profile to continue moving to the cutting station 3. After the profile is in place, the pressure block presses down, and the edge-cutting knife cuts off the end of the profile, completing the processing of one workpiece. Then, the lifting plate 9 lifts the profile that has just reached the edge-cutting station 2 again for edge-cutting processing, and the above actions are repeated.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
