Description

Technical Field

[0001] This utility model relates to the field of tool leveling technology, specifically to a continuous automatic tool straightening hydraulic leveling machine. Background Technology

[0002] In order to avoid deformation of the cutting tool during the machining process, the tool is often straightened and leveled after heat treatment.

[0003] Chinese patent document CN216096093U discloses a continuous automatic straightening and leveling machine for cutting tools and a continuous heat treatment furnace for cutting tools. The machine includes a conveyor, a moving support, a moving drive device, a support device, and a flattening and straightening device. The conveyor belt of the conveyor is used for automatically conveying cutting tools and is partially located above the support device. The flattening and straightening device includes a pressure plate and a lifting drive device. The lifting drive device is installed on the moving support and can drive the pressure plate to rise or fall. The moving support can move towards the feeding end under the drive of the moving drive device. When the pressure plate is pressed down into place by the lifting drive device, the moving support can move towards the discharge end with the conveyor belt.

[0004] In the above solution, the lifting drive device works with the pressure plate to press the cutter down on the support device on the conveyor belt and perform leveling work while moving with the conveyor belt. However, since the top of the support device needs to be in close contact with the conveyor belt for support, friction occurs between the support device and the conveyor belt during the movement, which affects the service life of the conveyor belt.

[0030] Example 1

[0031] like Figure 1-5 As shown, the present invention proposes a continuous automatic straightening hydraulic leveling machine for cutting tools, comprising a steel belt conveyor 1, a hydraulic cylinder 8, and a reset assembly;

[0032] One end of the steel belt conveyor 1, located inside the steel belt, is provided with a movable support extending above the steel belt and moving with the steel belt during use. This movable support is used to move with the cutter during use, so that the cutter can perform leveling work during the conveying process.

[0033] There are two reset components. The two reset components are respectively set on one side of the steel belt conveyor 1 and connected to the moving bracket. They are used to reset the position of the moving bracket during use so that the moving bracket is placed at the tool to be leveled.

[0034] The number of hydraulic cylinders 8 is at least two. The two hydraulic cylinders 8 are respectively installed on the inner top and top of the mounting frame 2, and their extended ends are facing the steel belt of the steel belt conveyor 1 and are arranged symmetrically. The extended ends of the hydraulic cylinders 8 are provided with pressure plates for moving towards the steel belt of the steel belt conveyor 1 in the use state and pressing and flattening the cutters transported on the steel belt.

[0035] In this embodiment, the hydraulic cylinder 8 simultaneously drives the pressure plate at the top and bottom of the inner side of the movable support to move towards the steel belt of the steel belt conveyor 1. The steel belt and the cutter placed on the steel belt are squeezed by the two pressure plates, and the friction generated by the two pressure plates squeezing the steel belt causes the movable support and the steel belt of the steel belt conveyor 1 to move synchronously. The cutter is leveled during the movement. At the same time, the cutter to be leveled moves through the steel belt to perform processing work, and the hydraulic cylinder 8 drives the pressure plate to reset. At the same time, the reset component resets the mounting frame 2, so that the mounting frame 2 moves to the processing station. By repeating the above steps, the continuous automatic straightening and leveling of the cutter is achieved, improving processing efficiency and accuracy, and ensuring that the cutter maintains stable performance during use.

[0036] Example 2

[0037] like Figure 1-3 As shown, the present invention proposes a continuous automatic straightening hydraulic leveling machine for cutting tools. The difference between this embodiment and the first embodiment is that the movable support includes a mounting frame 2, a movable wheel 3, and a reinforcing plate 4.

[0038] Mounting frame 2 is located at one end of steel belt conveyor 1 and is located inside the steel belt, extending to the top of the steel belt;

[0039] The number of movable wheels 3 is at least four, and the four movable wheels 3 are located at the bottom corners of the mounting frame 2. The bottom of the movable wheel 3 has a support, which can be the ground or a support plate set on the side of the steel belt conveyor 1 to limit the position of the mounting frame 2 and allow the mounting frame 2 to move along the length of the steel belt conveyor 1 by means of the movable wheels 3.

[0040] In an optional embodiment, the top and bottom ends of the mounting bracket 2 are provided with reinforcing plates 4, which are arranged in a grid pattern to enhance the strength of the bottom and top ends of the mounting bracket 2 during use, so as to prevent the upper and lower ends of the mounting bracket 2 from bending due to the reaction force generated by the pressure applied by the hydraulic cylinder 8 during use.

[0041] In this embodiment, the hydraulic cylinder 8 is fixedly installed in the middle and above the steel belt of the steel belt conveyor 1 by the mounting frame 2, so that the hydraulic cylinder 8 drives the pressure plate to apply pressure to the steel belt and the cutter. By setting the moving wheel 3 at the bottom of the mounting frame 2 and rolling it to the ground, the bearing force generated by the hydraulic cylinder 8 driving the pressure plate generates friction with the steel belt of the steel belt conveyor 1, thereby causing the steel belt to move synchronously with the mounting frame 2 through the moving wheel 3, and causing the pressure plate and the cutter to move synchronously, so that the cutter in the leveling process moves towards the discharge end and the cutter to be leveled moves towards the processing station, so that the cutter performs continuous leveling work.

[0042] Example 3

[0043] like Figure 5 As shown, the present invention proposes a continuous automatic straightening hydraulic leveling machine for cutting tools. The difference between this embodiment and the first embodiment is that the reset assembly includes a sleeve 6 and a telescopic rod 7.

[0044] The telescopic rod 7 is installed on the side of the steel belt conveyor 1. The telescopic rod 7 is one of an electric push rod, a pneumatic push rod, and a hydraulic push rod.

[0045] The sleeve 6 is fitted on the outside of the mounting frame 2 and slidably connected to the steel belt conveyor 1, and connected to the extended end of the telescopic rod 7. It is used to movably connect the telescopic rod 7 and the mounting frame 2 through the sleeve 6 during use, so as to prevent the mounting frame 2 from moving up and down due to the pressure of the hydraulic cylinder 8, which could damage the telescopic rod 7.

[0046] In an optional embodiment, a slider 12 is provided on the side of the sleeve 6, and a slide rail 5 connected to the steel belt conveyor 1 is installed on the side of the slider 12 to limit the position of the mounting frame 2 during use and prevent the mounting frame 2 from shifting.

[0047] In this embodiment, the sleeve 6 is fitted on the outside of the mounting frame 2, and the telescopic rod 7 is connected to the sleeve 6. The extended end of the telescopic rod 7 drives the mounting frame 2 to reset through the sleeve 6, thereby achieving precise reset of the mounting frame 2 and ensuring that the starting position of each straightening and leveling is consistent.

[0048] Example 4

[0049] like Figure 4 As shown, the present invention proposes a continuous automatic straightening hydraulic leveling machine for cutting tools. The difference between this embodiment and the first embodiment is that the pressure plate includes a connecting seat 9 and a leveling plate 11.

[0050] The connecting seat 9 is located at the extended end of the hydraulic cylinder 8 and is bolted to the hydraulic cylinder 8. The connecting seat 9 is arranged in a one-to-one correspondence with the hydraulic cylinder 8.

[0051] The leveling plate 11 is set at one end of the connecting seat 9. The width of the leveling plate 11 is the same as the width of the steel belt of the steel belt conveyor 1. It is used to level the cutters placed on the steel belt at different positions, so as to avoid the need to guide and limit the cutters during the transportation process.

[0052] In an optional embodiment, the connecting seat 9 is provided with reinforcing ribs 10 extending to the top edge of the flat plate 11. There are multiple reinforcing ribs 10, which are arranged at equal angles around the connecting seat 9. During use, the pressure on the connecting seat 9 is evenly distributed on the flat plate 11 through the reinforcing ribs 10, so as to ensure better leveling effect.

[0053] In this embodiment, the connecting seat 9 is bolted to the extended end of the hydraulic cylinder 8, and the hydraulic cylinder 8 drives the flat plate 11 to move toward the steel strip through the connecting seat 9. At the same time, the pressure is evenly transmitted to the flat plate 11 through multiple reinforcing ribs 10 to ensure that the cutting tool is subjected to uniform force during the leveling process.

[0054] In this invention, the cutting tool is transported to the processing station by the steel belt of the steel belt conveyor 1. Simultaneously, the hydraulic cylinders 8 at the top and bottom of the inner side of the mounting frame 2 drive the flat plate 11 to move towards the steel belt of the steel belt conveyor 1. This causes the two flat plates 11 to apply bidirectional pressure to the cutting tool, fixing it to the steel belt through pressure. The pressure from the flat plates 11 also generates friction between them and the steel belt of the steel belt conveyor 1, causing the mounting frame 2 to move with the cutting tool via the moving wheels 3. During this movement, the cutting tool is leveled by pressure. The machine operates by moving the leveling tool to the discharge end. Once the leveling tool reaches the processing station, the hydraulic cylinder 8 drives the leveling plate 11 to reset via the connecting seat 9, separating the leveling plate 11 from the steel belt of the steel belt conveyor 1. The telescopic rod 7 then drives the mounting frame 2 to move to the processing station via the sleeve 6, causing the mounting frame 2 to synchronously reset the hydraulic cylinder 8 and the leveling plate 11. By repeating the above steps, continuous automatic straightening and leveling of the tool is achieved, improving processing efficiency and accuracy, and ensuring stable performance of the tool during use.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
