Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a cutting tool for quickly removing tube clamps. Background Technology

[0002] In the field of machining, bobbin clamps are commonly used for supporting and rotating coils, wires, or tubes. When the coil is used up or the specifications are changed, the remaining bobbin needs to be removed from the mandrel. Currently, the commonly used manual method is for operators to repeatedly strike the bobbin with a hammer, screwdriver, or chisel, causing localized cracks and eventual bursting. The fragments are then removed one by one using a pry bar. This process has the following drawbacks: the impact load is uncontrolled, and the striking force is directly transmitted to the mandrel and bearing position through the bobbin, easily forming chisel marks, elliptical deformation, or even microcracks on the bushing surface, leading to decreased clamping accuracy and premature bearing failure; the bursting location is random, and fragments fly everywhere, posing a personal safety hazard; debris falling into the machine can cause secondary wear; the operation relies on experience, and a single removal takes 5–15 minutes. If the bobbin wall is thick or the material has high toughness, repeated striking with greater force is required, resulting in high labor intensity and low efficiency; the hammering process generates high-frequency noise and metal dust, which does not meet occupational health and environmental protection requirements.

[0003] Although some companies have tried using hydraulic pullers or turning methods, hydraulic pullers require specialized tooling and are limited by axial space; turning removes the mandrel surface coating, which is more costly. Therefore, the industry urgently needs a simple, quick, and mandrel-free tube removal solution that can be used at the machine tool without damaging the mandrel. Utility Model Content

[0017] Reference Figure 1According to a first aspect of the present invention, a cutting tool for quickly removing a tube clamp is characterized by comprising a grooving device 14, a base 1 for movably mounting the grooving device 14, and a round sleeve positioning device 2 for positioning the tube. The base 1 integrates the grooving device 14 and the round sleeve positioning device 2 into one unit. The grooving blade 22 extends into the sleeve body 21 to perform circumferential cutting on the tube, destroying its entire circumferential binding force in one go, eliminating the need for repeated hammering and prying steps, and reducing the removal time from several minutes to several seconds. The round sleeve positioning device 2 is fixedly mounted on the base 1. The base 1 is provided with a grooving blade 22 for circumferentially grooving the tube. The round sleeve positioning device 2 includes a sleeve body 21 in the shape of an arc or a cylinder for accommodating and positioning the tube to be cut. The grooving blade 22 is connected to the rotating shaft of the grooving device 14 and extends through into the sleeve body 21. The sleeve body 21 provides radial restraint to the tubing, and the grooving blade 22 cuts only along a preset circumference. The cutting depth is set once by the blade extension, ensuring it does not touch the internal bushing and completely eliminating the risk of bushing scratches, deformation, or breakage caused by traditional chiseling. The entire cutting process is completed by the rotating grooving blade 22. The operator only needs to hold the base 1 and feed it axially, eliminating the need for hammering and reducing labor intensity by more than 70%. It also avoids the risk of metal splatter and hand injuries caused by hammering. The arc / cylindrical sleeve body 21 fits snugly against the outer diameter of the tubing, forming a self-centering positioning that ensures the blade always cuts a groove of equal depth and width at the designed position on the tubing, with a cutting depth deviation of ≤0.1mm. This provides a uniform fracture line for subsequent manual removal, improving the success rate of dismantling.

[0018] According to an embodiment of the present invention, a cutting tool for quickly removing a cylinder clamp has at least the following beneficial effects: The present invention adopts an integrated structure of "grooving equipment 14 - base 1 - round sleeve positioning device 2 - grooving blade 22". The sleeve body 21 radially limits the cylinder and isolates it from the bushing. The rotating grooving blade 22 completes a circumferential equal-depth cut in one go, instantly destroying the cylinder's binding force, reducing the removal time from several minutes to several seconds, with a cutting depth deviation of ≤0.1mm. It completely avoids the internal bushing, thoroughly eliminating the risks of chiseling damage, deformation, and metal splashing caused by traditional hammering. The operator only needs to gently push the base 1 to complete the feed, reducing labor intensity by more than 70%. It also eliminates the need for complex external hydraulic and electrical control components. It is small in size and light in weight, and can utilize the power of the existing grooving equipment 14 anytime, anywhere to achieve efficient, labor-saving, zero-damage, and highly consistent rapid removal.

[0019] According to some embodiments of this utility model, the base 1 further includes a transparent protective sleeve 11 for detachably clamping the grooving device 14. The transparent protective sleeve 11 is located at one end of the base 1, and a slot is provided on the side of the transparent protective sleeve 11. Protrusions 12 are provided on both sides of the slot, and adjusting bolts 13 for adjusting the clamping tightness are provided through the two protrusions 12. The transparent protective sleeve 11 forms a detachable quick-clamp structure through the protrusions 12 on both sides of the slot and the adjusting bolts 13, which can quickly fix the grooving device 14 to the base 1 and can be loosened at any time for maintenance or replacement. The transparent material allows the operator to observe the position of the blade and the cutting state in real time, ensuring that the grooving of the cylinder is aligned in one go, avoiding miscutting or repeated positioning. While maintaining efficient and zero-damage dismantling, it further improves the ease of assembly, visual safety and equipment versatility.

[0020] According to some embodiments of this utility model, the round sleeve positioning device 2 is detachably installed on the base 1 by means of fixing bolts 25. The round sleeve positioning device 2 is detachably connected to the base 1 by means of fixing bolts 25, so that the same base 1 can be quickly fitted with sleeve bodies 21 of different inner diameters, adapting to various specifications of tubing; when the blade is worn or the work position needs to be changed, the positioning device can be completely removed for maintenance or storage simply by unscrewing the fixing bolts 25, which greatly shortens the line change time, reduces spare parts costs, and ensures that the positioning accuracy remains unchanged after repeated installation, further improving the versatility of cutting tools, on-site maintenance efficiency and service life.

[0021] According to some embodiments of this utility model, the inner diameter of the sleeve body 21 is adapted to the outer diameter of the cylinder. The precise fit between the inner diameter of the sleeve body 21 and the outer diameter of the cylinder forms a self-centering fit, which can instantly complete radial positioning and axial guidance without the need for an additional clamping mechanism. This ensures that the grooving blade 22 always cuts along the designed circumference of the cylinder, ensuring uniform cutting depth and width, and completely eliminating local overcutting or incomplete cutting caused by shaking or eccentricity. This clearance fit ensures smooth insertion and avoids excessive looseness, significantly improving grooving accuracy and finished product qualification rate. At the same time, it reduces the operator's adjustment and tool setting time, making the disassembly process faster, more stable, and more reliable.

[0022] According to some embodiments of this utility model, the grooving blade 22 is a rotatable blade, and its rotational power originates from the grooving device 14 built into the base 1. The rotatable blade is directly driven by the grooving device 14 built into the base 1, eliminating the need for an external power shaft or flexible transmission components, making the whole machine smaller and lighter; the blade speed and torque are uniformly controlled by the grooving device 14, which can quickly switch the optimal cutting parameters between different material tubes, ensuring a clean cut without tearing, and avoiding depth errors caused by uneven manual force application; the integrated power transmission also eliminates the risk of loose couplings or belt slippage, improving operational reliability, while reducing energy consumption and maintenance costs, and realizing plug-and-play, efficient and stable rapid dismantling operations.

[0023] The embodiments described above with reference to the accompanying drawings have been described in detail. However, the embodiments are not limited to those described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
