Description

Technical Field

[0001] The present invention relates to the field of sheet cutting and processing equipment, and specifically to a raw material cutting equipment for manufacturing ship side protection plates. Background Art

[0002] In the shipbuilding industry, the ship side protection plate is a key component to ensure the safe navigation of the ship and resist external impacts. Its manufacturing quality directly affects the overall performance and service life of the ship. And raw material cutting is the primary link in the manufacturing of ship side protection plates. The cutting accuracy and efficiency play a decisive role in the forming quality and production cycle of the protection plates. At present, traditional raw material cutting equipment for ship side protection plates mostly uses fixed cutting tools or simple mechanical transmission structures. During the cutting process, it is difficult to achieve precise positioning and flexible adjustment, and problems such as cutting shape deviation and insufficient dimensional accuracy often occur, resulting in increased raw material waste and rework costs. At the same time, due to the lack of an effective raw material fixing device, the raw material is prone to vibration and deviation during cutting, which not only affects the cutting quality but also poses a safety hazard. In addition, the chips generated during the cutting process cannot be discharged in time and accumulate in the cutting area, which not only interferes with the cutting operation but also accelerates the tool wear, reducing the service life and cutting efficiency of the equipment.

[0003] With the rapid development of the shipbuilding industry, the quality requirements for ship side protection plates are constantly increasing, and traditional cutting equipment has been difficult to meet the production requirements of high precision and high efficiency. Therefore, developing a raw material cutting equipment for manufacturing ship side protection plates that can achieve precise positioning cutting, stably fix the raw material, and effectively clean the chips has become an urgent need to solve the industry pain points and promote the progress of shipbuilding technology. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a raw material cutting equipment for manufacturing ship side protection plates, which solves the problems of inaccurate positioning, easy deviation of raw materials, large cutting resistance, and difficult chip cleaning of traditional raw material cutting equipment for ship side protection plates. Through designs such as a three-axis motion module, a pressing structure, cutting tool vibration, and pneumatic chip cleaning, precise cutting is achieved, ensuring cutting quality and efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A raw material cutting device for manufacturing a ship's side protection plate, including a processing table, on both sides of the top end of the processing table, Y-axis linear motion modules are fixedly installed. On the top ends of the sliders of the driving ends of the Y-axis linear motion modules, both are fixedly installed on both sides of the X-axis linear motion module through support frames. On the slider of the driving end of the X-axis linear motion module, a Z-axis motion module is fixedly installed. On the front end of the slider of the driving end of the Z-axis motion module, a housing is fixedly installed. At the bottom end of the housing, a positioning collar is fixedly installed. Inside the positioning collar, a cutting shaft is arranged. At the bottom end of the cutting shaft, a rotary cutting knife is fixedly installed. At a position above the positioning collar near the outer diameter of the cutting shaft, a bearing seat is fixedly installed. The bottom end of the outer ring of the bearing seat is connected to the top end of the positioning collar through a plurality of first return springs. On one end of the inner side wall of the housing, a fixed seat is fixedly installed. At the top end of the cutting shaft, an upper clamping plate is fixedly installed. On one side of the bottom end of the fixed seat, a lower clamping plate is fixedly installed. On the inner ends of the upper clamping plate and the lower clamping plate, a plurality of hemispherical protrusions are fixedly installed, and the positions of the upper and lower hemispherical protrusions are staggered with each other.

[0006] Preferably, on one side of the top end of the housing, a rotary motor is fixedly installed. The driving end of the rotary motor extends into the interior of the housing and is fixedly installed with a main shaft. On the outer diameter of the lower side of the main shaft, a driving gear is fixedly installed. On the outer diameter of the upper side of the cutting shaft, a driven gear is fixedly installed, and the inner end of the driven gear is meshed and connected with the inner end of the driving gear.

[0007] Preferably, on one side inside the housing, a transmission shaft is movably installed. On the outer diameter of the middle part of the main shaft, a driving wheel is fixedly installed. At the bottom end of the transmission shaft, a driven wheel is fixedly installed. Between the outer diameters of the driving wheel and the driven wheel, a transmission belt is connected.

[0008] Preferably, on the outer diameter of the middle part of the transmission shaft, a cam is fixedly installed. On both ends of the inner side wall of the housing near the cam, rubber piston chambers are fixedly installed. Inside the rubber piston chambers, piston plates are movably installed. The outer ends of the piston plates are connected to the inner walls of the corresponding rubber piston chambers through second return springs.

[0009] Preferably, on one side of the outer ends of the rubber piston chambers, air inlets are opened. On the other side of the outer ends of the rubber piston chambers, air outlets are opened. Inside the air inlets and the air outlets, one-way rubber valves are fixedly installed. On one side of the housing, a U-shaped pipe is fixedly installed, and both ends of the U-shaped pipe are respectively connected to the interiors of the two air outlets. At the bottom end of the U-shaped pipe, a jet pipe is fixedly installed, and the end of the jet pipe extends to one side of the rotary cutting knife and is installed with a nozzle.

[0010] Preferably, limit frames are fixedly installed on the inner sides of the driving end slides of the Y-axis linear motion module. Limit grooves are formed on one sides of the inner sides of the limit frames. Pressure plates are movably installed inside the limit grooves. The middles of the pressure plates are connected to the inner walls of the pressure plates through compression springs. Pressure rollers are movably installed on both sides of the inner ends of the pressure plates.

[0011] The present invention provides a raw material cutting device for manufacturing a ship's side protection plate. It has the following beneficial effects: 1. Through the limit frame, pressure plate and pressure roller structures installed on the inner side of the driving end slide of the Y-axis motion module, the present invention can continuously press the area around the raw material cutting area during cutting, effectively preventing the raw material from vibrating and shifting during the cutting process, providing a stable foundation for high-quality cutting operations, and reducing cutting errors and scrap rates caused by raw material shaking.

[0012] 2. The present invention utilizes the upper clamping plate on the cutting shaft and the lower clamping plate of the fixed seat to form a toothed structure through mutually staggered hemispherical protrusions. Cooperating with the first return spring, the rotary cutting tool can perform rapid reciprocating vibration up and down while rotating at high speed. This design not only significantly reduces the resistance during the cutting process of the tool, making the cutting smoother, but also promotes the timely discharge of the chips generated by cutting from the cutting area, avoiding chip accumulation or re-involvement in the cutting process, keeping the cutting area clean, and further improving the cutting efficiency and quality.

[0013] 3. When the main shaft rotates, it drives the transmission shaft and the cam to operate through the transmission belt, causing the two rubber piston chambers to cycle compress and reset, and realizing the inhalation and ejection of air by using the air pressure change. The ejected air blows away the chips generated by cutting through the U-shaped pipe, the air injection pipe and the nozzle, further ensuring that there is no chip interference in the cutting area, creating good conditions for the cutting process, improving the cutting quality, and prolonging the service life of the tool.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0017] Please refer to the attached Figure 1 - attached Figure 6 , the embodiment of the present invention provides a raw material cutting device for manufacturing a ship's side protection plate, as Figure 1As shown, the processing table 1 includes a processing table 1. The processing table 1 serves as the basic bearing component of the entire equipment and provides a stable plane support for the raw material cutting operation. Y-axis linear motion modules 2 are fixedly installed on both sides of the top of the processing table 1. The Y-axis linear motion module 2 adopts mature linear motion drive technology, and its driving end slide can perform precise linear motion along the Y-axis direction. The top of the driving end slide of the Y-axis linear motion module 2 is fixedly installed on both sides of the X-axis linear motion module 3 through a support frame. The support frame plays a role of stable connection, ensuring the reliable assembly between the Y-axis linear motion module 2 and the X-axis linear motion module 3, so that the X-axis linear motion module 3 can be moved with the help of the Y-axis linear motion module 2. The motion module 2 is driven to realize the position adjustment in the Y-axis direction. The X-axis linear motion module 3 is also based on the advanced linear motion principle. The Z-axis motion module 4 is fixedly installed on the driving end slide. Through the drive of the X-axis linear motion module 3, the Z-axis motion module 4 can move in the X-axis direction and cooperate with the Y-axis linear motion module 2 to realize flexible movement in a two-dimensional plane. The front end of the driving end slide of the Z-axis motion module 4 is fixedly installed with a shell 5. The shell 5 serves as a protective shell of the internal transmission structure, which not only provides protection for the internal components, but also plays a supporting and positioning role. The bottom end of the shell 5 is fixedly installed with a positioning ring 6, which is used to perform preliminary positioning of the cutting axis 7 The cutting shaft 7 is provided inside the positioning collar 6, and the cutting shaft 7 is the core component that drives the rotating cutting knife 8 to perform cutting operation. The bottom end of the cutting shaft 7 is fixedly installed with the rotating cutting knife 8. The rotating cutting knife 8 is made of high-strength and high-wear-resistant alloy material, and can efficiently cut the ship side protection plate raw material. The outer diameter of the cutting shaft 7 is fixedly installed with a bearing seat 13 near the upper position of the positioning collar 6. The bearing seat 13 provides stable support for the cutting shaft 7 to reduce friction and shaking during its rotation. The bottom end of the outer ring of the bearing seat 13 is connected to the top of the positioning collar 6 through a plurality of first return springs 14. The first return spring 14 has good elasticity and can provide buffering and return functions when the cutting shaft 7 is subjected to external force. A fixing seat 15 is fixedly installed at one end of the inner wall of the shell 5. The fixing seat 15 is used to fix the lower clamping plate 17, and provides a stable foundation for the cooperation of the upper clamping plate 16 and the lower clamping plate 17. The top of the cutting shaft 7 is fixedly installed with an upper clamping plate 16, and the bottom side of the fixing seat 15 is fixedly installed with a lower clamping plate 17. The inner ends of the upper clamping plate 16 and the lower clamping plate 17 are fixedly installed with a plurality of hemispherical protrusions 18, and the positions of the upper and lower hemispherical protrusions 18 are staggered. This staggered hemispherical protrusion 18 structure is the key design for realizing the vibration function of the cutting shaft 7.

[0018] Specifically, during the rotation of the cutting shaft 7, the upper clamping plate 16 at the top is also driven to rotate. By utilizing the toothed structure formed by the hemispherical protrusions 18 that intersect with each other between the upper clamping plate 16 and the lower clamping plate 17, and in cooperation with the first return spring 14, the upper clamping plate 16 continuously contacts and separates from the hemispherical protrusions 18 of the lower clamping plate 17 during rotation. Due to the elastic action of the first return spring 14, the high-speed rotating rotary cutting knife 8 is driven to perform rapid reciprocating vibration up and down. This not only helps to reduce the resistance suffered by the tool during cutting, making the cutting smoother, but also causes the debris generated by cutting to be discharged from the cutting area in a timely manner, preventing the debris from accumulating around the tool head or being re-involved in the cutting process, which is beneficial to maintaining the cleanliness of the cutting area and improving the cutting efficiency and quality.

[0019] In this embodiment, a rotary motor 9 is fixedly installed on one side of the top of the housing 5. The rotary motor 9 serves as the power source of the device. Adopting high-performance motor drive technology, it can provide stable and strong power output. The drive end of the rotary motor 9 extends into the interior of the housing 5 and is fixedly installed with a main shaft 10. The main shaft 10 is an important component for transmitting power, transmitting the power of the rotary motor 9 to the subsequent transmission structure. A driving gear 11 is fixedly installed on the outer diameter of the lower side of the main shaft 10. A driven gear 12 is fixedly installed on the outer diameter of the upper side of the cutting shaft 7, and the driven gear 12 is meshed and connected to the inner end of the driving gear 11. Through the meshing transmission of the driving gear 11 and the driven gear 12, the rotational movement of the main shaft 10 is transmitted to the cutting shaft 7, thereby driving the rotary cutting knife 8 to rotate at a high speed.

[0020] Furthermore, a transmission shaft 19 is movably installed on one side of the interior of the housing 5. The transmission shaft 19 can rotate flexibly inside the housing 5, playing a role in power transmission and conversion. A driving wheel 20 is fixedly installed on the outer diameter of the middle part of the main shaft 10. A driven wheel 21 is fixedly installed at the bottom end of the transmission shaft 19. The outer diameters of the driving wheel 20 and the driven wheel 21 are connected by a transmission belt 22. The transmission belt 22 has good transmission performance and can stably transmit the rotational movement of the driving wheel 20 to the driven wheel 21, thereby driving the transmission shaft 19 to rotate.

[0021] Furthermore, a cam 23 is fixedly installed on the outer diameter of the middle part of the transmission shaft 19. The cam 23 is a key component for realizing the cyclic operation of the pneumatic device. Rubber piston chambers 24 are fixedly installed at both ends of the inner side wall of the housing 5 near the cam 23. The rubber piston chambers 24 are made of flexible rubber material and can deform under pressure. Piston plates 25 are movably installed inside the rubber piston chambers 24 respectively. The piston plates 25 can perform reciprocating movements inside the rubber piston chambers 24 to realize the compression and inhalation of gas. The outer ends of the piston plates 25 are connected to the inner walls of the corresponding rubber piston chambers 24 through second return springs 26. The second return springs 26 provide power for the return of the piston plates 25.

[0022] Furthermore, air inlets 27 are provided on one side of the outer ends of the rubber piston chambers 24, and air outlets 28 are provided on the other side of the outer ends of the rubber piston chambers 24. One-way rubber valves 29 are fixedly installed inside both the air inlets 27 and the air outlets 28. The one-way rubber valves 29 can ensure that the gas can only flow in one direction, ensuring the normal operation of the pneumatic device. A U-shaped tube 30 is fixedly installed on one side of the housing 5, and the two ends of the U-shaped tube 30 are respectively communicated with the inside of the air outlets 28 on both sides. The U-shaped tube 30 functions to collect and guide the gas. A jet pipe 31 is fixedly installed at the bottom end of the U-shaped tube 30, and the end of the jet pipe 31 extends to one side of the rotary cutting knife 8 and is provided with a nozzle. The nozzle can eject the gas at a suitable angle and force, effectively cleaning the debris in the cutting area.

[0023] Specifically, when the main shaft 10 rotates, it will also drive the driving wheel 20 to rotate. Through the transmission of the transmission belt 22, the driven wheel 21 and the transmission shaft 19 are driven to rotate. The rotating transmission shaft 19 drives the cam 23 to rotate. When the cam 23 rotates, it will sequentially compress the two rubber piston chambers 24 on both sides. When one of the rubber piston chambers 24 is compressed, the piston plate 25 in the other rubber piston chamber 24 will be reset again through the action of the second return spring 26. This process repeats, realizing the cyclic compression and reset process of the two rubber piston chambers 24. When the rubber piston chamber 24 is reset, the internal air pressure decreases, and the external atmospheric pressure opens the one-way rubber valve 29 of the air inlet 27, and air enters the inside of the rubber piston chamber 24. When the rubber piston chamber 24 is compressed, the internal air pressure increases, and the external atmospheric pressure opens the one-way rubber valve 29 of the air outlet 28, and the air is discharged into the U-shaped tube 30 through the air outlet 28, and then sprayed out through the jet pipe 31 and the nozzle, blowing away the debris generated during cutting and further keeping the cutting area clean.

[0024] Furthermore, limit frames 32 are fixedly installed on the inner sides of the driving ends of the Y-axis linear motion modules 2. The limit frames 32 are used to limit the movement range of the pressing plates 34, ensuring the stability of their operation. Limit grooves 33 are provided on one side of the inner ends of the limit frames 32. The limit grooves 33 provide guidance for the sliding of the pressing plates 34. The pressing plates 34 are movably installed inside the limit grooves 33. The pressing plates 34 can slide up and down in the limit grooves 33 to realize the pressing and loosening of the raw materials. The middle parts of the pressing plates 34 are connected to the inner walls of the pressing plates 34 through pressing springs 35. The pressing springs 35 have appropriate spring coefficients, can provide sufficient pressing force, and can also make adaptive adjustments when the thickness of the raw materials changes. Pressing rollers 36 are movably installed on both sides of the inner ends of the pressing plates 34. The pressing rollers 36 are made of materials with low friction coefficients, can roll while pressing the raw materials, and can roll along with the movement of the rotary cutting knife 8, reducing the wear on the surface of the raw materials.

[0025] Specifically, while the driving end slide of the Y-axis linear motion module 2 is moving, it will also drive two pressure rollers 36 to move synchronously. The pressure rollers 36 will press on the surface of the raw material and move along with the subsequent movement of the rotary cutting knife 8. Due to the friction between the pressure rollers 36 and the surface of the raw material and their own rolling design, continuous pressing work around the cutting area of the raw material can be maintained, which can prevent the raw material from vibrating and shifting during the cutting process and improve the cutting quality.

[0026] Working principle: Place the raw material of the ship's side protection plate to be cut on the surface of the processing table 1. Then start the Y-axis linear motion module 2 and the X-axis linear motion module 3. The Y-axis linear motion module 2 and the X-axis linear motion module 3 are driven by servo motors and can achieve high-precision position control, driving the rotary cutting knife 8 at the bottom of the driving housing 5 to move to the position to be cut. While the slide table at the driving end of the Y-axis linear motion module 2 is moving, it will also drive two pressure rollers 36 to move synchronously. The pressure rollers 36 will press on the surface of the raw material and follow the movement during the subsequent movement of the rotary cutting knife 8. Due to the friction between the pressure rollers 36 and the surface of the raw material and their own rolling design, continuous pressing work around the cutting area of the raw material can be maintained, preventing the raw material from vibrating and shifting during the cutting process and improving the cutting quality. Then start the rotary motor 9. The rotary motor 9 drives the main shaft 10 to rotate. The main shaft 10 drives the driving gear 11 to rotate. The rotating driving gear 11 drives the driven gear 12 and the cutting shaft 7 to rotate through meshing transmission, thereby driving the rotary cutting knife 8 to rotate at high speed. Then control the high-speed rotating rotary cutting knife 8 to descend through the Z-axis linear motion module 4. The Z-axis linear motion module 4 precisely controls the descending distance of the rotary cutting knife 8 to cut the raw material. Cooperating with the X-axis linear motion module 3 and the Y-axis linear motion module 2, the raw material is cut into a predetermined shape. At the same time, during the rotation of the cutting shaft 7, it will also drive the upper clamping plate 16 at the top to rotate. Using the toothed structure formed by the hemispherical protrusions 18 that intersect with each other between the upper clamping plate 16 and the lower clamping plate 17, and cooperating with the first return spring 14, the upper clamping plate 16 continuously contacts and separates from the hemispherical protrusions 18 of the lower clamping plate 17 during rotation. Due to the elastic action of the first return spring 14, it drives the high-speed rotating rotary cutting knife 8 to perform rapid reciprocating vibration up and down. This not only helps to reduce the resistance suffered by the tool during cutting, making the cutting smoother, but also the vibration prompts the cutting debris to be discharged from the cutting area in time, preventing the debris from accumulating around the tool head or being re-involved in the cutting process, which is beneficial to keeping the cutting area clean and improving the cutting efficiency and quality. In addition, when the main shaft 10 rotates, it will also drive the driving wheel 20 to rotate. Using the transmission of the transmission belt 22, it drives the driven wheel 21 and the transmission shaft 19 to rotate. The rotating transmission shaft 19 drives the cam 23 to rotate. When the cam 23 rotates, it will sequentially compress the two rubber piston chambers 24 on both sides. When one of the rubber piston chambers 24 is compressed, the piston plate 25 in the other rubber piston chamber 24 will be reset through the action of the second return spring 26, and so on, realizing the cyclic compression and reset process of the two rubber piston chambers 24. When the rubber piston chamber 24 is reset, the internal air pressure decreases, and the external atmospheric pressure opens the one-way rubber valve 29 at the air inlet 27, and air enters the inside of the rubber piston chamber 24. When the rubber piston chamber 24 is compressed, the internal air pressure increases, and the external atmospheric pressure opens the one-way rubber valve 29 at the air outlet 28, and the air is discharged into the U-shaped tube 30 through the air outlet 28 and then sprayed out through the spray pipe 31 and the nozzle.Blow away the debris generated during cutting, further keep the cutting area clean, avoid interference of the debris with the cutting process, and improve the cutting quality.
