Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a punching machine for processing high-performance fiber composite material sheets. Background Technology

[0002] High-performance fiber composite panels are a new type of material composed of high-performance fibers and a resin matrix. Using high-strength, high-modulus fibers, such as carbon fiber and aramid fiber, as reinforcement, they are tightly bonded to the resin matrix through advanced molding processes to form panels with excellent properties. This material is lightweight, high-strength, corrosion-resistant, and highly designable, and is widely used in aerospace, wind turbine blades, rail transportation, and new energy vehicles. The processing of high-performance fiber composite panels is a complex process involving multiple steps, mainly including raw material preparation, molding processes, and subsequent processing. Punching is a crucial step in the processing of high-performance fiber composite panels, involving precisely punching the required number and specifications of holes in the panel to meet specific assembly or functional requirements.

[0003] Traditional methods for punching composite material boards rely on manual alignment of the pre-drilled points of the board with the punch head of the punching machine, followed by the up-and-down movement of the punch head to complete the punching. First, manual operation is cumbersome, requiring repeated adjustments to the board position to ensure alignment accuracy, which is not only time-consuming and labor-intensive but also prone to alignment deviations due to improper operation. Second, the punching speed is limited by the worker's skill level and operating speed, making it difficult to meet the needs of large-scale production. Furthermore, the boards after manual punching still need to be stacked for subsequent deburring, with the punching and deburring processes being carried out separately, resulting in low production efficiency. Therefore, to solve the above problems, a high-performance punching machine for processing fiber composite material boards is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of low production efficiency in existing technologies by proposing a high-performance punching machine for processing fiber composite material boards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A punching machine for processing high-performance fiber composite material boards includes a conveyor belt mechanism and a material board. The conveyor belt mechanism is used to drive the material board to move. A punching table is installed on the conveyor belt mechanism. A punching mechanism is provided between the punching table and the conveyor belt mechanism. The punching mechanism includes a punching head that moves up and down on the punching table. A backing plate is installed inside the conveyor belt mechanism. The punching head moves up and down to punch and punch holes in the material board on the backing plate.

[0007] The conveyor belt mechanism is also equipped with a grinding mechanism, which includes grinding rollers. The grinding rollers are symmetrically rotated on the conveyor belt mechanism, and the two grinding rollers rotate in opposite directions. Dust suction covers are provided on the outside of the two grinding rollers. The two grinding rollers grind and deburr the material plate after punching.

[0008] The above technical solution further includes:

[0009] The conveyor belt mechanism includes symmetrically arranged support rails, a control motor is mounted on the side of the support rails, a drive shaft is symmetrically rotatably connected between the two support rails, and a gearbox for power transmission is mounted between the control motor and the drive shaft.

[0010] Two gear rings are symmetrically mounted on the two drive shafts. Standard chain conditions are sleeved and connected on the two gear rings on one side of the support rail. Multiple threaded clamping plates are mounted on the two standard chain conditions.

[0011] The material plate is installed between multiple threaded clamping plates, the stamping table and the dust collection hood are both installed on two support rails, the abutment is installed between the two support rails, and a collection box is installed at the bottom of the abutment.

[0012] The stamping mechanism includes a stamping motor mounted on the top of the stamping table, a transmission rod rotatably connected to the inner side of the stamping table, a first driving flywheel mounted on the output end of the stamping motor, a first driven flywheel mounted on the end of the transmission rod near the stamping motor, and a first belt sleeved between the first driving flywheel and the first driven flywheel.

[0013] Guide columns are symmetrically installed between the stamping table and the support rail. The two guide columns slide relative to each other with the stamping plate head. A shock-absorbing spring connected to the stamping table and the stamping plate head is provided on the outside of the guide column. Anti-vibration blocks and cams are symmetrically installed on the transmission rod. Guide heads are symmetrically fixedly connected to the stamping plate head. The guide heads slide relative to the groove of the cam.

[0014] The grinding mechanism also includes a second driving flywheel installed at the end of the transmission rod away from the first driven flywheel, and a second driven flywheel installed at the end of the top grinding roller near the second driving flywheel. A second belt is sleeved and connected between the second driven flywheel and the second driving flywheel.

[0015] Each of the two grinding rollers is equipped with a reversing gear at the end away from the second driven flywheel, and the two reversing gears mesh with each other.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, continuous punching of sheet metal is achieved through the cooperation of the conveyor belt mechanism and the punching mechanism, with the punching force and position controlled by a PLC. This effectively avoids alignment deviations and uneven force caused by manual operation, significantly improving punching accuracy and consistency. Simultaneously, it greatly shortens processing time, increases production efficiency, and ensures high-quality output from the punching of composite material sheets.

[0018] 2. In this utility model, the grinding mechanism integrated on the conveyor belt mechanism performs immediate grinding and deburring treatment on the punched sheet material through counter-rotating grinding rollers. This eliminates burrs and sharp edges generated during the punching process, improves the surface smoothness of the sheet material, and avoids the cumbersome step of separate grinding required in traditional processing. The dust collection hood effectively collects the dust generated during grinding, improves the working environment, reduces the potential hazards of dust to equipment and operators, and realizes an efficient and environmentally friendly composite material sheet processing flow.

[0026] 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.

[0027] Example

[0028] like Figures 1-6 As shown, the present invention proposes a punching machine for processing high-performance fiber composite material boards, including a conveyor belt mechanism and a material board 5. The conveyor belt mechanism is used to drive the material board 5 to move. A punching table 2 is installed on the conveyor belt mechanism. A punching mechanism is provided between the punching table 2 and the conveyor belt mechanism. The punching mechanism includes a punching head 27 that moves up and down on the punching table 2. A backing plate 212 is installed inside the conveyor belt mechanism. The punching head 27 moves up and down to punch and punch holes in the material board 5 on the backing plate 212.

[0029] The conveyor belt mechanism is also equipped with a grinding mechanism, which includes grinding rollers 32. The grinding rollers 32 are symmetrically rotated on the conveyor belt mechanism. The two grinding rollers 32 rotate in opposite directions. Dust suction covers 3 are provided on the outside of the two grinding rollers 32. The two grinding rollers 32 grind and deburr the material plate 5 after punching.

[0030] Furthermore, when the material plate moves above the stamping table 2, the stamping mechanism begins to operate. Specifically, the stamping head 27 on the stamping table 2 begins to move up and down. During the descent, the stamping head 27 aligns with the material plate 5 on the abutment plate 212, applying sufficient pressure to stamp and punch holes. The abutment plate 212 is equipped with a positioning sensor. When the material plate moves above the stamping table 2, the stamping head 27 begins to descend and punch holes, while the abutment plate 212 supports the material plate, ensuring the stability and accuracy of the stamping process.

[0031] After punching and drilling are completed, the material plate continues to move with the conveyor belt and enters the working area of ​​the grinding mechanism. The grinding mechanism includes two symmetrically rotating grinding rollers 32 that rotate in opposite directions. As the material plate passes by, the two grinding rollers 32 work together to grind its surface, removing burrs and sharp edges generated during the punching process. Simultaneously, a dust collection hood 3 is installed outside the grinding rollers 32 to effectively collect dust generated during the grinding process, maintaining a clean working environment.

[0032] The conveyor belt mechanism includes symmetrically arranged support rails 1, a control motor 12 is mounted on the side of the support rails 1, a drive shaft 14 is symmetrically rotatably connected between the two support rails 1, and a gearbox 13 for power transmission is mounted between the control motor 12 and the drive shaft 14.

[0033] Two drive shafts 14 are symmetrically mounted with gear rings 11. Two gear rings 11 on one side of the support rail 1 are fitted with standard chain conditions 10. Multiple threaded clamping plates 213 are mounted on the two standard chain conditions 10.

[0034] Material plate 5 is installed between multiple threaded clamping plates 213, stamping table 2 and dust hood 3 are both installed on two support rails 1, abutment plate 212 is installed between two support rails 1, and a collection box 4 is installed at the bottom of abutment plate 212.

[0035] Furthermore, the support rails 1 are symmetrically arranged to form the frame of the conveyor belt mechanism. A control motor 12 mounted on its side provides the power source. The control motor 12 transmits power to the drive shaft 14 via a gearbox 13. Two drive shafts 14 are symmetrically rotatably connected between the support rails 1, forming synchronously rotating power shafts. Gear rings 11 symmetrically mounted on the drive shafts 14 mesh with the standard chain condition 10. The rotation of the gear rings 11 drives the chain 10 in cyclic motion. Multiple threaded clamping plates 213 are fixed on the standard chain condition 10. The cyclic motion of the chain 10 drives the threaded clamping plates 213 to move synchronously.

[0036] The clamping force of the threaded clamping plate 213 can be adjusted by tightening the bolts. Based on the thickness, hardness, and surface condition of the material plate 5, a suitable clamping force can be selected to ensure that the material plate will not slip or be damaged during the conveying process.

[0037] The material plate 5 is clamped between multiple threaded clamping plates 213 and is continuously and stably conveyed through the transmission of the chain 10. The stamping table 2 and the dust hood 3 are both installed on the support rail 1. When the material plate 5 moves above the stamping table 2 with the chain 10, it works with the stamping mechanism to complete the punching. The collection box 4 is installed at the bottom of the back plate 212 to collect the punching or falling debris and keep the working area clean.

[0038] After punching, the material plate continues to move to the grinding station, where the dust hood 3 covers the grinding area and collects the dust generated during grinding.

[0039] The stamping mechanism includes a stamping motor 20 mounted on the top of the stamping table 2, a transmission rod 24 rotatably connected to the inner side of the stamping table 2, a first driving flywheel 21 mounted on the output end of the stamping motor 20, a first driven flywheel 23 mounted on the end of the transmission rod 24 near the stamping motor 20, and a first belt 22 sleeved between the first driving flywheel 21 and the first driven flywheel 23.

[0040] Guide columns 210 are symmetrically installed between the stamping table 2 and the support rail 1. The two guide columns 210 slide relative to each other with the stamping plate head 27. A shock-absorbing spring 211 connected to the stamping table 2 and the stamping plate head 27 is provided on the outside of the guide column 210. A shock-absorbing block 28 and a cam 26 are symmetrically installed on the transmission rod 24. A guide head 29 is symmetrically fixedly connected to the stamping plate head 27. The guide head 29 slides relative to the groove of the cam 26.

[0041] Furthermore, when the material plate moves above the stamping table 2, the stamping motor 20 starts, and its output drives the first drive flywheel 21 to rotate. The first drive flywheel 21 transmits power to the first driven flywheel 23 through the first belt 22, which is fixed to one end of the transmission rod 24. The transmission rod 24 starts to rotate under the drive of the flywheel, providing a power source for subsequent stamping actions;

[0042] Guide columns 210 are symmetrically installed between the stamping table 2 and the support rail 1, passing through the sliding hole of the stamping plate head 27 to ensure stable vertical movement of the stamping plate head. Shock-absorbing springs 211 are sleeved on the outside of the guide columns 210, with both ends connected to the stamping table 2 and the stamping plate head 27 respectively, to buffer the impact force during the stamping process and protect the material plate and equipment.

[0043] The cams 26, symmetrically mounted on the transmission rod 24, rotate with the rod body. Their outer edges are designed with a raised arc shape. The bottom of the stamping plate head 27 is symmetrically fixed with guide heads 29. The guide heads 29 are embedded in the grooves of the cams 26 to form a sliding fit. When the transmission rod 24 rotates, the rotation of the cams 26 drives the stamping plate head 27 to make vertical reciprocating motion along the guide post 210 through the guide heads 29, thereby realizing the stamping action. The anti-vibration block 28 is installed on the transmission rod 24. The mass of the anti-vibration block 28 is greater than that of the cams 26, ensuring that the center of gravity of the transmission rod 24 is at the axis of the transmission rod 24.

[0044] The grinding mechanism also includes a second driving flywheel 214 installed at the end of the transmission rod 24 away from the first driven flywheel 23, a second driven flywheel 31 installed at the end of the top grinding roller 32 close to the second driving flywheel 214, and a second belt 25 connected to the second driven flywheel 31 and the second driving flywheel 214.

[0045] Each of the two grinding rollers 32 has a reversing gear 33 installed at the end away from the second driven flywheel 31, and the two reversing gears 33 mesh with each other.

[0046] The second driving flywheel 214, installed at the end of the transmission rod 24 away from the first driven flywheel 23, transmits power to the second driven flywheel 31 at one end of the top grinding roller 32 via the second belt 25, driving the top grinding roller 32 to rotate. The reversing gears 33 installed at the ends of the two grinding rollers 32 away from the second driven flywheel 31 mesh with each other, so that the two grinding rollers 32 rotate synchronously in opposite directions, ensuring that both sides of the material plate 5 can be evenly ground when passing through. At the same time, the continuous rotation of the transmission rod 24 maintains the stable speed of the grinding roller 32 through the flywheel-belt system. Combined with the symmetrically arranged dust collection hoods 3, the grinding dust is effectively collected, realizing efficient and low-pollution grinding and deburring operations.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
