Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a metal product processing and cutting device. Background Technology

[0002] In the field of metal processing, cutting is an indispensable and crucial step in the manufacturing process, widely used in various industries. As modern industry continues to demand higher precision, efficiency, and appearance quality from parts, metal cutting technology is also constantly evolving and being optimized.

[0003] However, during metal cutting, especially when processing thin sheet or cylindrical metals, the workpiece's cut surface often undergoes varying degrees of thermal or mechanical deformation due to the material's low rigidity, differences in thermal conductivity, and concentrated heat input and mechanical stress generated during cutting. This deformation not only affects the geometric accuracy and dimensional stability of the parts but may also reduce assembly quality.

[0004] Therefore, the above problems need to be solved. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a metal product processing and cutting device to solve the problem of surface deformation during the cutting of thin plate and cylindrical materials in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution: a metal product processing and cutting device, comprising: a moving mechanism disposed on a working platform; a pushing mechanism slidably connected to a pushing mechanism for pushing materials; a cutting mechanism disposed on the working platform for cutting materials; a grinding mechanism disposed opposite to the cutting mechanism on the working platform for grinding the material cuts; a clamping mechanism disposed between the pushing mechanism and the grinding mechanism for radially inward clamping of the materials; a rotating inner support mechanism movably disposed on the device, opposite to the pushing mechanism and adjacent to the clamping mechanism, for radially outward clamping of the materials; a feeding point disposed at the bottom of the rotating inner support mechanism for feeding materials; and a feeding mechanism disposed at the lower end of the working platform and located at the feeding point, movably connected to the rotating inner support mechanism.

[0007] To achieve the above technical solution, this utility model uses a clamping mechanism and a rotating inner support mechanism to work together to achieve stable clamping of thin cylindrical materials from both inside and outside, effectively suppressing vibration and deformation during the cutting process; combined with a moving mechanism and a pushing mechanism, automatic feeding and positioning are achieved; after the cutting mechanism completes precise cutting, the grinding mechanism automatically trims the cut; and the unloading mechanism achieves smooth unloading with the cooperation of the rotating inner support mechanism.

[0008] In one embodiment of the present invention, the clamping mechanism includes multiple sets of movable positioning blocks and bearings, wherein at least four sets of movable positioning blocks are provided on the inner ring of the bearings, and the movable positioning blocks clamp the material.

[0009] To achieve the above technical solution, the clamping mechanism utilizes the rotational characteristics of the bearings to ensure the synchronicity and concentricity of the movement of each positioning block. The uniform application of force at multiple points effectively avoids the concentration of clamping stress. It can not only firmly clamp thin-walled cylindrical materials and prevent them from deforming or shifting during the cutting process, but also adapt to changes in material size within a certain range, thus improving the reliability and adaptability of clamping.

[0010] In one embodiment of the present invention, the rotating inner support mechanism includes a connecting seat and a support seat, wherein an electric rotating component is provided in the connecting seat and is connected to the support seat through a rotating rod.

[0011] To achieve the above technical solution, the rotating inner support mechanism drives the rotating rod through an electric rotating component, which in turn drives the support seat to achieve precise rotational movement. This allows the mechanism to provide radial support and positioning for the inside of the cylindrical material while simultaneously driving the material and the holding mechanism to rotate synchronously, thus ensuring stability during the cutting process.

[0012] In one embodiment of this utility model, the support base is provided with multiple sets of inner support slide rails, multiple sets of inner support sliders, and multiple sets of inner support connecting plates. One end of the inner support connecting plate is slidably connected to the inner support slide rail through the inner support slider. The other end of the inner support connecting plate on the same side is connected to a moving rod, and the moving rod passes through the support base and is connected to the drive mechanism.

[0013] To achieve the above technical solution, the rotating inner support mechanism sets an inner support slide rail, a slider, and an inner support connecting plate on the support base, and the drive mechanism pushes the inner support connecting plate to move radially along the slide rail through the moving rod, thereby realizing precise control of synchronous expansion and contraction of multiple sets of inner support points. This structure enables the inner support mechanism to adapt to cylindrical materials with different inner diameters, quickly complete self-centering expansion and contraction, and, in conjunction with the electric rotation function, achieve synchronous rotation of materials while having stable inner support.

[0014] In one embodiment of this utility model, the support base is provided with multiple sets of arc-shaped limiting grooves, and the connecting rod is located within the limiting grooves.

[0015] To achieve the above technical solution, the structure guides and limits the radial extension and retraction of the inner support connecting plate, effectively restricting the trajectory of the inner support slider during the movement and preventing it from deflecting; at the same time, the arc design is compatible with the curvature of the inner wall of the cylindrical material, enhancing the stability and fit of the support structure.

[0016] In one embodiment of the present invention, the inner support connecting plate is connected to an inner support rod on the side away from the inner support slider, and multiple sets of inner support pads are provided on the inner support rod, with a cutting distance left between the inner support pads.

[0017] By implementing the above technical solution, the structure achieves multi-point uniform support for the inner wall of the cylindrical workpiece, enhancing clamping stability. Moreover, the reserved gap between the inner support blocks provides sufficient clearance for the cutting tool, avoiding interference during the cutting process and ensuring smooth cutting operations. At the same time, the block structure can disperse the support stress, prevent local deformation of the workpiece, and effectively protect the quality of the inner surface of the workpiece.

[0018] In one embodiment of this utility model, the feeding mechanism includes a feeding base, a rotating bolt, a first connecting plate, a second connecting plate, a cylinder, a piston rod, and a moving module; the feeding base is slidably connected to the moving module, the second connecting plate is vertically arranged on the side of the feeding base, the second connecting plate is movably connected to the first connecting plate through the rotating bolt, the feeding base is also provided with a cylinder, the piston rod of the cylinder abuts against the first connecting plate, and the first connecting plate is vertically connected to the connecting seat of the rotating inner support mechanism.

[0019] To achieve the above technical solution, the feeding mechanism controls the extension and retraction of the cylinder piston rod to drive the first connecting plate to tilt, thereby causing the rotating inner support mechanism connected to it to tilt downward as a whole, so that the cut workpiece sleeved on its inner support rod loses support, automatically detaches under the action of gravity and falls into the feeding point, thus achieving smooth feeding.

[0020] In one embodiment of the present invention, during the cutting process, the inner support pad abuts against the inner wall of the material cut, and the positioning block of the clamping mechanism abuts against the outer wall of the material cut. Both the outer layer of the inner support pad and the positioning block are provided with a flexible buffer layer.

[0021] To achieve the above technical solution, the inner support pad and the positioning block of the clamping mechanism provide bidirectional rigid support for the material cutting position from the inner wall and the outer wall, respectively. Combined with the flexible buffer layer on the outer layer, it can effectively resist the mechanical stress and vibration generated by cutting and prevent the workpiece from deforming or the edge from collapsing.

[0022] As described above, the metal product processing and cutting device of this utility model has the following beneficial effects:

[0023] 1. This utility model achieves stable clamping of thin cylindrical materials from both inside and outside by setting up a clamping mechanism and a rotating inner support mechanism to work together, effectively suppressing vibration and deformation during the cutting process; combined with the moving mechanism and the pushing mechanism, automatic feeding and positioning are achieved; after the cutting mechanism completes precise cutting, the grinding mechanism automatically trims the cut; and the unloading mechanism achieves smooth unloading with the cooperation of the rotating inner support mechanism.

[0024] 2. The rotating inner support mechanism of this utility model achieves precise control of synchronous expansion and contraction of multiple sets of inner support points by setting an inner support slide rail, a slider and an inner support connecting plate on the support base, and pushing the inner support connecting plate radially along the slide rail by the driving mechanism through the moving rod. This structure enables the inner support mechanism to adapt to cylindrical materials with different inner diameters, quickly complete self-centering expansion and contraction, and, in conjunction with the electric rotation function, achieve synchronous rotation of materials while having stable inner support.

[0025] 3. The feeding mechanism of this utility model drives the first connecting plate to tilt by controlling the extension and retraction of the cylinder piston rod, thereby causing the rotating inner support mechanism connected to it to tilt downward as a whole, so that the cut workpiece on its inner support rod loses support, automatically detaches under the action of gravity and falls into the feeding point, thus achieving smooth feeding.

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please see Figure 1This utility model provides a metal product processing and cutting device, including: a moving mechanism 1, which is disposed on a work platform 0. The moving mechanism 1 includes a sliding module, a moving slide rail, and a moving plate; the sliding module is arranged parallel to the moving slide rail and is slidably connected to the moving plate.

[0032] Pushing mechanism 2, which is slidably connected to pushing mechanism, is set on the moving plate and is used to push materials.

[0033] Cutting mechanism 3 is set on the working platform 0 and is used to cut materials.

[0034] The grinding mechanism 4 is positioned opposite the cutting mechanism 3 on the work platform 0. It is used to grind the cut edges of materials.

[0035] The clamping mechanism 5 is located between the pushing mechanism and the grinding mechanism 4 and is used to clamp the material radially inward.

[0036] The rotating inner support mechanism 6 is movably mounted on the device, opposite to the pushing mechanism, and adjacent to the clamping mechanism 5, for radially outward clamping of the material.

[0037] The material feeding point 7 is located at the bottom of the rotating inner support mechanism 6 and is used for material feeding.

[0038] The unloading mechanism 8 is located at the lower end of the working platform 0 and at the unloading point 7, and is movably connected to the rotating inner support mechanism 6.

[0039] By setting the clamping mechanism 5 and the rotating inner support mechanism 6 to work together, the thin plate cylindrical material is stably clamped in both the inner and outer directions, effectively suppressing vibration and deformation during the cutting process; combined with the moving mechanism 1 and the pushing mechanism 2, automatic feeding and positioning are achieved; after the cutting mechanism 3 completes the precise cutting, the grinding mechanism 4 automatically trims the cut; and the unloading mechanism 8 achieves smooth unloading with the cooperation of the rotating inner support mechanism 6.

[0040] For further details, please refer to Figure 2 The clamping mechanism 5 includes multiple sets of movable positioning blocks and bearings. At least four sets of movable positioning blocks are provided on the inner ring of the bearings, and the movable positioning blocks clamp the material.

[0041] The clamping mechanism 5 utilizes the rotational characteristics of the bearings to ensure the synchronicity and concentricity of the movement of each positioning block. The multi-point uniform force application effectively avoids the concentration of clamping stress. It can not only firmly clamp thin-walled cylindrical materials and prevent them from deforming or shifting during the cutting process, but also adapt to material size changes within a certain range, thus improving the reliability and adaptability of clamping.

[0042] Furthermore, the rotating inner support mechanism 6 includes a connecting seat 601 and a support seat 602. An electric rotating component is installed in the connecting seat 601 and is connected to the support seat 602 through a rotating rod.

[0043] The rotating inner support mechanism 6 drives the rotating rod through an electric rotating component, which in turn drives the support base 602 to achieve precise rotational movement. This allows the material to be radially supported and positioned inside the cylindrical material while simultaneously rotating synchronously with the support mechanism, ensuring stability during the cutting process.

[0044] Furthermore, the support base 602 is provided with multiple sets of inner support slide rails 603, multiple sets of inner support sliders 607, and multiple sets of inner support connecting plates 604. One end of the inner support connecting plate 604 is slidably connected to the inner support slide rail 603 through the inner support slider 607. The other end of the inner support connecting plate 604 is connected to a moving rod 608, which passes through the support base 602 and is connected to the drive mechanism.

[0045] The rotating inner support mechanism 6, by setting an inner support slide rail 603, a slider and an inner support connecting plate 604 on the support base 602, and by driving the inner support connecting plate 604 to move radially along the slide rail through the moving rod 608, achieves precise control of synchronous expansion and contraction of multiple sets of inner support points; this structure enables the inner support mechanism to adapt to cylindrical materials with different inner diameters, quickly complete self-centering expansion and contraction, and, in conjunction with the electric rotation function, achieve synchronous rotation of materials while having stable inner support.

[0046] For further details, please refer to Figure 3 The support base 602 is provided with multiple sets of arc-shaped limiting grooves 606, and the connecting rod is located in the limiting grooves 606.

[0047] This structure guides and limits the radial extension and retraction of the inner support connecting plate 604, effectively restricting the trajectory of the inner support slider 607 during movement and preventing it from deflecting. At the same time, the arc-shaped design is compatible with the curvature of the inner wall of the cylindrical material, enhancing the stability and fit of the support structure.

[0048] For further details, please refer to Figure 2 The inner support connecting plate 604 is connected to the inner support rod 605 on the side away from the inner support slider 607. Multiple sets of inner support pads 609 are provided on the inner support rod 605, and the cutting distance is maintained between the inner support pads 609. The inner support rod 605 is adaptively set according to the required cutting length of the material and adopts a plug-in design for quick switching during processing.

[0049] This structure provides multi-point uniform support for the inner wall of the cylindrical workpiece, enhancing clamping stability. Furthermore, the reserved gap between the inner support blocks 609 provides ample clearance for the cutting tool, preventing interference during the cutting process and ensuring smooth cutting operations. At the same time, the block structure can disperse support stress, prevent local deformation of the workpiece, and effectively protect the quality of the inner surface of the workpiece.

[0050] Furthermore, the unloading mechanism 8 includes an unloading base 801, a rotating bolt 802, a first connecting plate 803, a second connecting plate 804, a cylinder 805, a piston rod 806, and a moving module 807. The unloading base 801 is slidably connected to the moving module 807. The second connecting plate 804 is vertically arranged on the side of the unloading base 801. The second connecting plate 804 is movably connected to the first connecting plate 803 through the rotating bolt 802. The unloading base 801 is also equipped with a cylinder 805. The piston rod 806 on the cylinder 805 abuts against the first connecting plate 803. The first connecting plate 803 is vertically connected to the connecting seat 601 of the rotating inner support mechanism 6.

[0051] The unloading mechanism 8 controls the extension and retraction of the piston rod 806 of the cylinder 805 to drive the first connecting plate 803 to tilt, thereby causing the rotating inner support mechanism 6 connected to it to tilt downward as a whole, so that the cut workpiece on its inner support rod 605 loses support, automatically detaches under the action of gravity and falls into the unloading point 7, thus achieving smooth unloading.

[0052] Furthermore, during the cutting process, the inner support pad 609 abuts against the inner wall of the material cut, and the positioning block of the clamping mechanism 5 abuts against the outer wall of the material cut. Both the inner support pad 609 and the positioning block have a flexible buffer layer on their outer layers.

[0053] The inner support pad 609 and the positioning block of the clamping mechanism 5 provide bidirectional rigid support for the material cutting position from the inner wall and the outer wall, respectively. Combined with the flexible buffer layer on the outer layer, they can effectively resist the mechanical stress and vibration generated by cutting and prevent the workpiece from deforming or the edge from collapsing.

[0054] Furthermore, the workflow of a metal product processing and cutting device includes:

[0055] The thin cylindrical material to be cut is inserted into the clamping mechanism 5, and then pushed to the rotating inner support mechanism 6 by the pushing mechanism 2, and then placed on the inner support rod 605 to ensure that the cutting area is roughly aligned with the cutting mechanism 3.

[0056] Furthermore, the drive mechanism of the rotating inner support mechanism 6 is activated, pushing the moving rod 608, which causes the inner support connecting plate 604 to slide radially outward along the inner support slide rail 603 on the support base 602. The inner support connecting plate 604 then pushes the inner support rod 605 and its inner support pads 609 to move outward synchronously until multiple sets of inner support pads 609 tightly and evenly abut against the inner wall of the cylindrical material, achieving radial inward clamping and center positioning, and ensuring that the cutting end is located between the inner support pads 609.

[0057] Furthermore, the movable positioning block of the clamping mechanism 5 moves radially inward under the drive until the flexible buffer layer at its front end tightly adheres to the outer wall of the cutting area of ​​the cylindrical material, achieving outward clamping. At this time, the material is firmly clamped in the cutting area by the inner support pad 609 and the positioning block from both the inside and outside, and the flexible buffer layer protects the surface of the workpiece.

[0058] Furthermore, after the material is firmly clamped in both directions, the cutting mechanism 3 is activated. At this time, the rotating inner support mechanism 6 can drive the material to rotate synchronously to perform the circumferential cutting operation.

[0059] Furthermore, after the cutting is completed, the cutting mechanism 3 is reset and the grinding mechanism 4 is started. Its grinding head moves to the cutting surface and automatically grinds and repairs the burrs or uneven parts of the cut to improve the quality of the cut.

[0060] Furthermore, after grinding is completed, the cylinder 805 of the feeding mechanism 8 is activated, the piston rod 806 retracts, and pushes the first connecting plate 803 to tilt around the rotating bolt 802. Under its own gravity, the material slides down along the tilted inner support rod 605, detaches from the rotating inner support mechanism 6, and falls into the feeding point 7 at its bottom.

[0061] Furthermore, after the material is fed, the piston rod 806 of cylinder 805 resets, driving the first connecting plate 803 and the rotating inner support mechanism 6 back to their initial horizontal positions. At this time, the pushing mechanism 2 continues to push the material forward, repeating the cyclic cutting steps.

[0062] This invention achieves the linkage of clamping, cutting, grinding, and unloading throughout the entire process, and effectively suppresses the cutting deformation of thin-walled cylindrical parts through bidirectional clamping.

[0063] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
