Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a corner cutting device for hydraulic joint production. Background Technology

[0002] Hydraulic fittings are accessories that connect hydraulic components (such as pumps, delivery pipelines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, etc.) to form a closed loop, serving a connecting function to ensure the normal operation of the hydraulic system.

[0003] Existing edge cutting devices used in the production of hydraulic joints leave numerous burrs on the cut surface after cutting, resulting in an uneven surface that requires further grinding. It is impossible to grind the cut surface simultaneously with the cutting process. Therefore, it is necessary to provide an edge cutting device for the production of hydraulic joints to solve the aforementioned technical problems. Summary of the Invention

[0004] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a corner cutting device for hydraulic joint production is proposed to solve the problem that after cutting hydraulic joints, there are many burrs on the cut surface of the hydraulic joint, resulting in a very uneven cut surface that still needs further grinding. It is impossible to grind the cut surface at the same time as cutting.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a corner cutting device for hydraulic joint production, including a base, a long support rotatably mounted on the side wall of the base, a return spring fixedly mounted between the bottom side of the long support and the outer wall of the base, a motor fixedly mounted on the top side of the long support, a first sprocket fixedly mounted on the output shaft of the motor, a cutter assembly rotatably mounted on the side wall of the top of the long support away from the motor via a first rotating shaft, a second sprocket fixedly mounted on the first rotating shaft, a transmission chain mounted on both the first and second sprockets, a protective cover detachably mounted on the side wall of the long support and outside the cutter assembly, a pressure rod fixedly mounted on the outer wall of the protective cover, and a cooling component for cooling the surface of the cutter assembly mounted on the outer wall of the protective cover.

[0006] Furthermore, the cutting assembly includes a cutting blade, and multiple mounting slots are evenly provided on both sides of the outer wall of the cutting blade, each mounting slot including a first mounting slot and a second mounting slot.

[0007] Furthermore, the first and second mounting slots are detachably equipped with fine and coarse grinding discs via bolts, which are used to perform coarse and fine grinding on the cut surfaces of the hydraulic connectors, respectively.

[0008] Furthermore, the cooling assembly includes a cylinder fixedly mounted on the outer wall of the protective cover. Multiple air inlets are evenly provided on the side wall of the cylinder away from the protective cover. An impeller is rotatably mounted inside the cylinder via a second rotating shaft. An air pipe connected to the inside of the cylinder is fixedly mounted on the top of the cylinder. An air guide pipe is fixedly mounted on the end of the air pipe away from the cylinder. Air nozzles are fixedly mounted on both sides of the bottom end of the air guide pipe.

[0009] Furthermore, the two air nozzles are located on both sides of the cutter assembly, the air guide tube is fixedly installed at the top of the inner cavity of the protective cover, and an exhaust port is provided on one side of the top of the protective cover.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: By setting a cutting assembly with multiple coarse and fine grinding discs, and designing the fine and coarse grinding discs to gradually move away from the center of the cutting blade, this allows the coarse grinding discs to first contact the cut surface of the hydraulic connector when the cutting blade is pressed down after cutting the hydraulic connector, achieving a coarse grinding effect. As the cutting blade continues to press down, the fine grinding discs can further refine the surface on top of the coarse grinding, resulting in a flat cut surface for the hydraulic connector, eliminating the need for subsequent grinding of the cut surface. Furthermore, when the cutter rotates, it can drive the second shaft to rotate via the first shaft, providing driving force for the impeller's rotation. When the impeller rotates, it can draw in external air and blow it onto both sides of the cutter's outer wall through the air pipe, air guide pipe, and air nozzle, accelerating the airflow speed around the cutter's outer wall and achieving the effect of cooling the cutter. This prevents the cutter from deforming due to high temperature, thereby extending the cutter's service life. Moreover, the coarse and fine grinding discs are designed separately from the first and second mounting slots, allowing for disassembly and replacement when either the coarse or fine grinding disc is damaged, eliminating the need to replace the entire coarse and fine grinding discs, thus saving costs.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] A corner cutting device for hydraulic connector production includes a base 1, a long support 2 rotatably mounted on the side wall of the base 1, a clamp for holding the hydraulic connector on the base 1, a return spring fixedly mounted between the bottom side of the long support 2 and the outer wall of the base 1, a motor 3 fixedly mounted on the top side of the long support 2, a first sprocket fixedly mounted on the output shaft of the motor 3, a cutter assembly 4 rotatably mounted on the side wall of the top of the long support 2 away from the motor 3 via a first rotating shaft, a second sprocket fixedly mounted on the first rotating shaft, a transmission chain mounted on both the first and second sprockets, a protective cover 6 detachably mounted on the side wall of the long support 2 and outside the cutter assembly 4, a pressure rod 5 fixedly mounted on the outer wall of the protective cover 6, and a cooling assembly 7 for cooling the surface of the cutter assembly 4 on the outer wall of the protective cover 6.

[0015] In this embodiment, the cutter assembly 4 includes a cutter 41, and multiple mounting slots are evenly provided on both sides of the outer wall of the cutter 41. Each mounting slot includes a first mounting slot 42 and a second mounting slot 43.

[0016] In this embodiment, the first mounting groove 42 and the second mounting groove 43 are detachably provided with fine grinding discs 44 and coarse grinding discs 45 by bolts, which are used to perform coarse grinding and fine grinding on the cut surface of the hydraulic connector respectively.

[0017] In this embodiment, the cooling assembly 7 includes a cylindrical body 71 fixedly mounted on the outer wall of the protective cover 6. Multiple air inlets 72 are evenly provided on the side wall of the cylindrical body 71 away from the protective cover 6. An impeller 73 is rotatably mounted inside the cylindrical body 71 via a second rotating shaft. An air pipe 74 communicating with the inside of the cylindrical body 71 is fixedly mounted on the top of the cylindrical body 71. An air guide pipe 75 is fixedly mounted on one end of the air pipe 74 away from the cylindrical body 71. Air nozzles 76 are fixedly mounted on both sides of the bottom end of the air guide pipe 75. The first rotating shaft and the second rotating shaft are connected by a coupling.

[0018] In this embodiment, two air nozzles 76 are located on both sides of the cutter assembly 4, and an air guide pipe 75 is fixedly installed on the top of the inner cavity of the protective cover 6. An exhaust port is provided on one side of the top of the protective cover 6.

[0019] Working principle: In use, the hydraulic connector to be cut is stably clamped by the clamp. The motor 3 is started and drives the cutter assembly 4 to rotate rapidly through the chain and the first and second sprockets. Then, the hand holds the pressure rod 5 and presses down on the long bracket 2. At this time, the cutter assembly 4 moves closer to the clamp. After the cutter 41 contacts the hydraulic connector, it cuts. As the cutter 41 continues to move down along the cut on the surface of the hydraulic connector, the coarse grinding disc 45 first contacts the cut, thereby coarsely grinding the outer wall of the cut. As the cutter 41 continues to move down, the fine grinding disc 44 contacts the outer wall of the cut, completing the secondary fine grinding of the outer wall of the cut. After the cutting is completed, the clamp is released from the hydraulic connector, and the cut hydraulic connector can be taken out.
