Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting device for a clamping machine. Background Technology

[0002] In the manufacturing of water-cured medical splints, after the impregnation or coating process, the product needs to be precisely cut. A common cutting method is to directly cut the product using a rotating circular blade mounted on a movable cutting table.

[0003] The existing circular blade cutting device operates by having a rotating blade directly press against and cut into the material. This method has the following disadvantages: ① Without a stop bar to pre-compress and guide the material, it is prone to displacement, warping, or stretching at the moment of cutting, resulting in uneven cuts, burrs, or even tearing, severely affecting product aesthetics and quality. ② A large portion of the high-speed rotating blade is directly exposed in the operating area, posing a significant risk of cuts to the operator's hands; debris ejected during cutting may also cause injury. ③ The blade directly impacts and pulls the material, resulting in uneven force distribution and potentially causing premature blade wear or chipping.

[0004] Therefore, there is an urgent need in the existing technology for a clamping machine cutter device that can effectively guide materials, ensure the straightness of the cutting line, and improve safety and cutting quality. Utility Model Content

[0005] In order to overcome the above-mentioned defects of existing circular knife cutting devices, this utility model provides a clamping machine cutting device.

[0006] The technical solution adopted by this utility model is as follows: A clamping machine cutting device includes a gantry, a linear guide rail, a knife table, a rotary circular knife assembly, and a lifting cylinder. The linear guide rail is arranged along the gantry, the knife table is set on the slide of the linear guide rail, the rotary circular knife assembly is installed on the knife table, the lifting cylinder is arranged on both sides of the gantry, and also includes a front stop bar. The front stop bar is arranged parallel to and fixed to the gantry to form a cutting slit. The blade of the rotary circular knife assembly extends into the cutting slit, and its cutting edge protrudes from below the cutting slit.

[0007] Preferably, the width of the slit is adjustable.

[0008] Preferably, the front baffle is provided with fixing blocks at both ends, and the fixing blocks are provided with connecting elongated holes. The fixing blocks are connected to the gantry by bolts passing through the connecting elongated holes.

[0009] Preferably, the rotating circular blade assembly is externally provided with a protective cover that covers the portion of the blade exposed above the kerf.

[0010] Preferably, at least two lifting cylinders are arranged side by side on both sides of the gantry.

[0011] Preferably, the rotary blade assembly is an electric blade or a pneumatic blade.

[0012] This utility model has the following beneficial effects: 1. Neat cut edges: By setting a fixed front stop bar, a narrow kerf is formed with the gantry. During cutting, the material is pre-flattened and precisely guided by the front stop bar, which effectively prevents the material from shifting, lifting or stretching at the moment of cutting, thereby ensuring that the cut edge is straight, burr-free and tear-free, improving the appearance quality and consistency of the product. 2. Enhanced safety performance: Most of the area of ​​the rotating circular cutter is confined above the kerf and covered by a protective cover, allowing only the necessary cutting edges to protrude from below the kerf, reducing the risk of operators coming into contact with the blade, while also effectively preventing debris from flying during cutting; 3. Long blade life: The blade extends from the kerf for cutting, resulting in a smoother cutting process and avoiding direct impact on the material. The material is held in place by the front guard, reducing vibration and pulling during cutting, resulting in more even force distribution on the blade, thus reducing chipping and abnormal wear, and extending the blade's lifespan. 4. High adaptability: The adjustable kerf width design allows the device to flexibly adapt to materials of different thicknesses and properties, expanding the processing range of the equipment. Quick adjustments can be achieved through a simple bolt connection structure, making it convenient to operate and highly practical. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0018] In the embodiments, such as Figures 1-3The diagram shows a cutting device used in a clamping machine, comprising a gantry 1, a linear guide rail 2, a blade holder 4, a rotary blade assembly 5, and a lifting cylinder 6. The linear guide rail 2 is arranged along the gantry 1, the blade holder 4 is mounted on a slide 3 of the linear guide rail 2, the rotary blade assembly 5 is mounted on the blade holder 4, and the lifting cylinder 6 is arranged on both sides of the gantry 1. It also includes a front stop 7, which is parallel to and fixed to the gantry 1, forming a cutting slit 8. The blade 9 of the rotary blade assembly 5 extends into the cutting slit 8, with its cutting edge protruding from below the slit 8. The front stop 7 pre-compresses and physically limits the material before cutting, effectively preventing displacement, warping, and tensile deformation of the material during cutting, thus ensuring the straightness and flatness of the cut edge and avoiding burrs and tearing. Moreover, most of the blade 9 is hidden above the cutting slit 8, with only the cutting edge exposed. This design naturally limits the contact range between the operator and the rotating blade, reducing the risk of cuts.

[0019] In the embodiments, such as Figure 3 As shown, the width of the cutter slit 8 is adjustable. The specific adjustment structure is as follows: Fixed blocks 10 are provided at both ends of the front stop 7. Each fixed block 10 has a connecting elongated hole 11, and the fixed blocks 10 are connected to the gantry 1 via bolts passing through the connecting elongated holes 11. By adjusting the width of the cutter slit 8, this device can flexibly handle products of different thicknesses and materials, expanding the processing capacity and application range of the equipment. Using the connecting elongated holes 11 on the fixed blocks 10 and the bolt connection, stepless or segmented adjustment of the relative position between the front stop 7 and the gantry 1 is achieved. The operator only needs to loosen the bolts, move the front stop 7 to the desired position, and then tighten them again; the adjustment process is very convenient and quick. While achieving the adjustment function, this structure ensures that the front stop 7 is firmly fixed in the working state through bolt tightening, guaranteeing the stability of the cutting process.

[0020] In the embodiments, such as Figure 1 As shown, the rotating circular blade assembly 5 is externally equipped with a protective cover 12, which covers the portion of the blade 9 exposed above the kerf 8. The protective cover 12 completely covers the portion of the blade 9 exposed above the kerf 8, further eliminating the possibility of accidental contact between the operator's hands or other body parts and the high-speed rotating blade. Furthermore, the protective cover 12 acts as a physical barrier, effectively preventing tiny debris that may be generated during cutting from flying upwards, thus improving safety.

[0021] In the embodiments, such as Figures 1-2 As shown, at least two lifting cylinders 6 are arranged side by side on both sides of the gantry 1. The arrangement of two or more lifting cylinders 6 on both sides ensures that the blade holder 4 experiences uniform and stable force during lifting, avoiding jamming or tilting that may occur due to single-point drive. The multi-point support structure enhances the rigidity and stability of the entire cutting device during operation, helping to ensure cutting accuracy, especially preventing vibration when cutting resistance is high.

[0022] In this embodiment, the rotary blade assembly 5 uses either an electric or pneumatic blade. Users can choose the most economical and convenient drive solution based on the energy configuration on site, enhancing the flexibility and environmental adaptability of the equipment and enabling it to better adapt to different industrial application scenarios.

[0023] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
