Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a cutting device for sheet metal processing on a water jet loom. Background Technology

[0002] As a highly efficient textile equipment, the water jet loom contains a large number of sheet metal parts in its structure. These sheet metal parts typically undergo multiple processes during production, including cutting, bending, and stamping. Among these processes, precise cutting (edge ​​trimming) of the sheet metal parts is a crucial step in ensuring dimensional accuracy and assembly quality.

[0003] Traditional edge trimming methods often involve manual operation using handheld cutting equipment or general-purpose stamping dies. Manual operation suffers from low efficiency, high labor intensity, and inconsistent cutting accuracy heavily influenced by the operator's experience, as well as posing certain safety hazards. While creating specialized dies for specific sheet metal shapes can guarantee a certain level of precision, it is costly, has a long production cycle, is poorly adaptable to multi-variety, small-batch production models, and presents inconvenience in storing and managing the dies.

[0004] Furthermore, some existing simple edge-cutting devices typically have fixed or inconveniently adjustable heights and positions for their cutting components, making them unsuitable for processing sheet metal parts of varying thicknesses or cutting positions, and lacking flexibility. During the cutting process, the positioning and fixing of the sheet metal parts are often unreliable, easily leading to poor edge cutting or tool damage due to workpiece displacement.

[0005] Therefore, there is an urgent need in this field for a dedicated edge-cutting device that can adapt to sheet metal parts of different specifications, is easy to operate, has high edge-cutting accuracy, and is safe. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cutting edge device for sheet metal processing on water jet looms. It has the advantages of high cutting accuracy, stable quality, flexible adjustment, strong adaptability, and reliable positioning. It solves the problems of poor cutting accuracy and consistency, insufficient equipment flexibility and adaptability, unreliable workpiece positioning, and high cost and long cycle of traditional special molds.

[0007] (II) Technical Solution To achieve the aforementioned objectives of high cutting precision, stable quality, flexible adjustment, strong adaptability, and reliable positioning, this utility model provides the following technical solution: a cutting device for sheet metal processing on a water jet loom, comprising a base and a placement platform disposed on the upper side of the base. Support columns are respectively provided at both ends of the placement platform, and lifting columns are provided inside the support columns. A support frame is installed on the top of the lifting columns, and a hydraulic mechanism is provided inside the support frame. A cutting frame is provided at the output end of the hydraulic mechanism, and multiple cutting blades are provided inside the cutting frame.

[0008] Preferably, the hydraulic mechanism includes a hydraulic cylinder, which is fixedly installed on the inner wall of the support frame.

[0009] Preferably, the outer side of the placement platform is provided with a limiting block that works in conjunction with the limiting groove, and the limiting block has a slot inside, which is located below the cutting blade at the corresponding position.

[0010] Preferably, the upper end of the base is provided with a mounting bracket, and the bottom of the mounting bracket is provided with a support block.

[0012] (III) Beneficial Effects Compared with existing technologies, this utility model provides a cutting device for sheet metal processing on a water-jet loom, which has the following advantages: This cutting device for sheet metal processing on a water-jet loom provides stable and powerful downward pressure through a hydraulic mechanism. Combined with the precise guidance of the cutting blade within the limiting groove, and the synergistic effect of the positioning column and positioning plate, it ensures a smooth and precise cutting process, effectively guaranteeing the cutting quality of the sheet metal parts and resulting in good product consistency.

Detailed Implementation

[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] Example: Please refer to Figure 1-3A cutting device for sheet metal processing of a water jet loom includes a base 1 and a placement platform 4 set on the upper side of the base 1. Support columns 3 are respectively provided at both ends of the placement platform 4, and lifting columns 6 are provided inside the support columns 3. A support frame 7 is installed on the top of the lifting columns 6, and a hydraulic mechanism is provided inside the support frame 7. A cutting machine frame 9 is provided at the output end of the hydraulic mechanism, and multiple cutting blades 10 are provided inside the cutting machine frame 9.

[0017] The base 1 serves as the foundation and basic support structure for the entire device. It is typically constructed from heavy-duty steel plates or profiles, ensuring the stability and rigidity of the equipment during operation and preventing wobbling during cutting. The base usually has internal or side spaces and interfaces for installing other components. The placement platform 4 is the work platform that directly supports and secures the sheet metal parts to be processed. Its surface needs to be flat and may undergo heat treatment to increase wear resistance. It serves as the reference surface for the entire cutting operation. The support column 3 and lifting column 6 form a crucial height adjustment mechanism. The support column 3 is fixed to the base 1, acting as an outer sleeve. The lifting column 6 is nested inside the support column 3 and can move vertically up and down relative to the support column. This double-column structure (usually at least two, located at both ends of the placement platform) ensures the smoothness and synchronization of the upper structure's lifting and lowering, avoiding the risk of overturning that may occur with single-point support. The support frame 7 spans across the top of the two lifting columns 6, forming a "bridge" structure. It transmits the supporting force of the lifting columns to the core cutting execution components and serves as the mounting base for the hydraulic mechanism and the edge-cutting frame. The hydraulic mechanism, as the core power source, is characterized by its ability to provide enormous, stable, and controllable downward pressure. This is crucial for cutting sheet metal edges in a single operation, offering greater power and a cleaner, crisper cut than pneumatic or electric screw drives. The trimming frame 9 is a tool holder that mounts and secures multiple cutting blades. It connects directly to the output of the hydraulic mechanism, transmitting hydraulic power to the cutting blades. Its structural strength must be high enough to withstand the enormous cutting reaction force and prevent deformation. Multiple cutting blades 10 are the tools that directly perform the cutting task. Depending on the shape of the sheet metal part (e.g., requiring simultaneous removal of burrs on both sides or all four sides), multiple cutting blades can be mounted, enabling simultaneous multi-sided cutting in a single stamping operation, significantly improving production efficiency. The blades are typically made of high-speed steel or cemented carbide to ensure sharpness and durability.

[0018] The hydraulic mechanism includes a hydraulic cylinder 8, which is fixedly installed on the inner wall of the support frame 7. The output end of the hydraulic cylinder 8 is fixedly connected to the top of the trimming frame 9. The trimming frame 9 has a limiting groove 16 inside, and the cutting blade 10 is installed on the inner wall of the limiting groove 16.

[0019] Hydraulic cylinder 8 is the concrete implementation of the hydraulic mechanism. It receives high-pressure oil from a hydraulic station, driving its piston rod to extend or retract. It is fixed to the top of the inner wall of the support frame 7, ensuring the stress point is centered and the structure is stable. The end of the piston rod of hydraulic cylinder 8 is directly and fixedly connected to the top center or key stress point of the trimming frame 9. This direct connection ensures efficient power transmission and avoids unnecessary energy loss and structural deformation. The limiting groove 16 is a crucial precision positioning and guiding structure. It is a long, narrow groove machined into the body of the trimming frame 9. The groove wall clamps and guides the cutting blade 10, preventing lateral movement of the blade during cutting and enhancing its rigidity under lateral forces, thus preventing breakage or excessive wear.

[0020] The outer side of the placement platform 4 is provided with a limiting block 17 that works in conjunction with the limiting groove 16, and the inside of the limiting block 17 is provided with a slot 15, which is located below the corresponding cutting blade 10.

[0021] The limiting block 17 is a modular component located at the edge of the placement table 4. Its core function is as a "lower mold" or "anvil". Its cooperation with the limiting groove 16 embodies the principle of "one-to-one correspondence between upper and lower parts". Directly below the movement trajectory of each cutting blade 10 on the trimming frame 9, there is a corresponding limiting block 17. This ensures that when the cutting blade falls, it can accurately cut into the slot 15 of the limiting block. The slot 15 provides space for the cutting blade 10 to continue its downward movement after completing the cutting action. Without this slot, the cutting edge of the cutting blade would directly impact the solid surface of the limiting block, causing the blade to quickly become dull or even chip. The slot ensures a smooth cutting process and extends the lifespan of the cutting blade, while also preventing the cutting force from directly acting on the surface of the placement table 4, protecting its precision.

[0022] The upper end of the base 1 is provided with a mounting bracket 13, and the bottom of the mounting bracket 13 is provided with a support block 5. The support block 5 is located inside the base 1. The interior of the base 1 is provided with a lifting electric push rod 14, and the output end of the lifting electric push rod 14 is fixedly connected to the bottom of the lifting column 6. The bottom of the base 1 is provided with a support frame 2, and the bottom end of the lifting electric push rod 14 is located inside the support frame 2.

[0023] The mounting frame 13 and the support block 5 form the mounting base for the placement platform 4 and the support column 3. The mounting frame 13 provides the structural connection surface, while the support block 5 extends deep into the base, effectively transferring and distributing the upper load to the main structure of the base 1. The lifting electric push rod 14 is the power source for coarse overall height adjustment. The electric push rod is a mechanism that converts the rotary motion of a motor into linear thrust. It is installed inside the base 1, with its push rod tip fixed to the bottom of the lifting column 6. When it is necessary to adjust the cutting height to accommodate workpieces of different thicknesses, the electric push rod 14 is activated, which directly lifts or pulls the lifting column 6, thereby driving the entire support frame 7, hydraulic cylinder 8, and cutting frame 9 to rise and fall together. This adjustment range is large, used to set an initial, wide range of working heights.

[0024] The inside of the trimming frame 9 is provided with a positioning column 11, and the top of the positioning column 11 is fixedly connected to the inner wall of the trimming frame 9. The bottom of the positioning column 11 is provided with a positioning plate 12, and the positioning plate 12 is located directly above the placement table 4.

[0025] In this process, when the hydraulic cylinder 8 drives the trimming frame 9 downwards, the more prominent positioning plate 12 contacts the sheet metal part placed on the placement table 4 before the cutting blade 10. As the trimming frame 9 continues to descend, the positioning plate 12 presses down on the sheet metal part, firmly fixing it to the placement table 4 to prevent it from moving or bouncing during subsequent cutting. Only after the sheet metal part is fully pressed down does the cutting blade 10 contact the workpiece and begin cutting. With the workpiece firmly fixed, cutting vibration is reduced, resulting in higher cut quality.

[0026] Working Principle: The operator activates the lifting electric push rod 14 according to the thickness of the sheet metal part to be processed, adjusting the height of the entire cutting head (support frame, trimming frame, etc.) to ensure a suitable initial distance between the cutting blade 10 and the placement table 4. Based on the edge position to be cut on the sheet metal part, the cutting blade 10 is moved and secured in the limiting groove 16 of the trimming frame 9. Simultaneously, the limiting block 17 is installed or adjusted on the placement table 4 to ensure that its slot 15 is aligned with the cutting blade's descent trajectory. The sheet metal part is placed on the placement table 4 and roughly positioned in the predetermined processing area. The hydraulic cylinder 8 starts working, driving the trimming frame 9 downwards. First, the positioning plate 12 contacts and presses against the sheet metal part. The trimming frame 9 continues to descend, the cutting blade 10 contacts the edge of the sheet metal part, and under the strong hydraulic pressure, cooperates with the limiting block 17 below, cutting off excess edge material like scissors. The cutting blade finally falls into the slot 15 of the limiting block, completing the cutting stroke. After cutting, hydraulic cylinder 8 reverses direction, driving the trimming frame 9 to rise. The cutting blade 10 first retracts from the slot 15 and the workpiece, then the positioning plate 12 releases its clamping force on the workpiece, and finally the entire cutting head returns to its initial height. The operator removes the trimmed sheet metal part and cleans the debris from the worktable, preparing for the next workpiece.
