Description

Technical Field

[0001] This utility model relates to the field of forging cutting technology, specifically a saw for cutting wear-resistant forgings for marine applications. Background Technology

[0002] In the shipbuilding and repair industry, a wide variety of high-strength, high-wear-resistant forging materials are used, such as shafts, flanges, and connecting parts. These marine wear-resistant forgings typically feature high hardness and high toughness.

[0003] Traditional ship-mounted wear-resistant forging cutting saws require frequent manual adjustment of the support frame position, wasting operation time and reducing efficiency. Furthermore, the saw blade is in direct contact with the metal during operation, and prolonged friction can easily cause breakage, reducing service life. Additionally, cooling and lubrication are not possible. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sawing machine for cutting wear-resistant forgings for marine applications, which has advantages such as saving time and labor, and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned time-saving and labor-saving objectives, this utility model provides the following technical solution: a saw for cutting wear-resistant forgings for ships, including a housing, a cutting mechanism and a saw blade. A pressure plate is installed on the upper end of the housing, and an electric lifting mechanism is installed at each of the four corners of the upper end of the pressure plate. The upper end of the electric lifting mechanism is connected to the cutting mechanism. A drive groove is installed in the middle of the front wall of the housing. A drive motor is installed in the rear of the drive groove. A ball screw is mounted on the drive motor through the motor shaft. A screw slide is driven on the ball screw. A sliding frame is installed on the upper end of the screw slide. Support rods are installed at the four corners of the upper end of the sliding frame. Support frames are installed on the upper ends of the support rods. Fixing plates are installed at the four corners of the upper end of the support frames. Electric hydraulic cylinders are installed on the outer ends of the fixing plates. The front ends of the electric hydraulic cylinders pass through the fixing plates and are fitted with arc-shaped clamps.

[0006] As a further improvement of this utility model, the saw blade is made of cemented carbide material, which improves the strength of the saw blade.

[0007] As a further improvement of this utility model: two limiting grooves are provided at the bottom of the drive groove, and two rollers are provided on both sides of the lower end of the sliding frame.

[0010] As a further improvement of this utility model: spray tanks are installed on both sides of the saw blade, and two spray pipes are provided at the front end of each spray tank. The cutting fluid penetrates into the contact area and forms a lubricating film on the metal surface, reducing direct contact between metals, thereby improving service life, preventing saw blade wear from causing breakage, and also cooling and lubricating the saw blade surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the drive motor is started, and the drive motor drives the ball screw to rotate through the motor shaft, which drives the screw slide to move forward, drives the sliding frame to move forward, and drives the support frame to move forward, thereby driving the marine forging to move forward and enabling manual pulling, saving time and effort.

[0012] 2.

[0015] 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.

[0016] It should be noted that the cutting mechanism 4 is existing technology and is common knowledge to those skilled in the art, so it will not be described in detail here.

[0017] Please see Figures 1-3 In this embodiment of the utility model, the saw for cutting wear-resistant forgings for ships includes a housing 1, a cutting mechanism 4 and a saw blade 5. A pressure plate 3 is installed on the upper end of the housing 1, and an electric lifting mechanism 6 is installed at each of the four corners of the upper end of the pressure plate 3. The upper end of the electric lifting mechanism 6 is connected to the cutting mechanism 4. A drive groove 9 is installed in the middle of the front wall of the housing 1. A drive motor 14 is installed in the rear of the drive groove 9. A ball screw 13 is installed on the drive motor 14 through the motor shaft. A screw slide is installed on the ball screw 13. A sliding frame 10 is installed on the upper end of the screw slide. Support rods 11 are installed at the four corners of the upper end of the sliding frame 10. A support frame 8 is installed on the upper end of the support rods 11. Fixing plates 7 are installed at the four corners of the upper end of the support frame. Electric hydraulic cylinders 15 are installed on the outer ends of the fixing plates 7. The front ends of the electric hydraulic cylinders 15 pass through the fixing plates 7 and are fitted with arc-shaped clamps 16.

[0018] The saw blade 5 is made of cemented carbide, which improves its strength. The drive groove 9 has two limiting grooves at its bottom, and the sliding frame 10 has two rollers 12 on both sides of its lower end. The rollers 12 roll within the limiting grooves, facilitating movement and providing a limiting position. The front sides of the housing 1 have storage compartments 2, each with two placement plates for storing items. The front of the arc-shaped clamp 16 has two pressure blocks 17 made of anti-slip rubber, which increases friction with the marine forgings and improves anti-slip properties. The saw blade 5 has spray tanks 18 on both sides, each with two spray pipes at its front. Cutting fluid penetrates the contact area, forming a lubricating film on the metal surface, reducing direct metal-to-metal contact, thus improving service life, preventing wear and breakage of the saw blade 5, and providing cooling and lubrication.

[0019] The working principle of this utility model is as follows: The device is fixedly installed on the ship, connected to a power source to ensure it is energized, and the marine forging is placed on the pressure plate 3, with the front end of the forging placed on the support frame 8. Four electric hydraulic cylinders 15 are activated, causing four arc-shaped clamps 16 to move inward, pressing and fixing the sides of the marine forging. The drive motor 14 is then activated, driving the ball screw 13 to rotate via its shaft. This causes the ball screw slide to move forward, which in turn moves the sliding frame 10 forward, and the support frame 8 forward, thus moving the marine forging forward. Manual pulling is also possible, saving time. Effortless operation: When the designated cutting position for marine forgings is reached, the cutting mechanism 4 is activated, driving the saw blade 5 to rotate. Four electric lifting mechanisms 6 drive the cutting mechanism 4 downward to cut the marine forgings. The cutting fluid in the spray tank 18 is sprayed onto the saw blade 5. The cutting fluid penetrates into the contact area and forms a lubricating film on the metal surface, reducing direct contact between metals and thus improving service life. It also prevents the saw blade 5 from wearing out and breaking. Furthermore, it can cool and lubricate the surface of the saw blade 5. The saw blade 5 is made of hard alloy material, which improves its strength. Items can also be stored in the storage compartment 2.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
