Description

Technical Field

[0001] This utility model relates to the field of cutting equipment and material cutting technology, and in particular to a pneumatic bevel cutter. Background Technology

[0002] Existing bevel cutters, such as the utility model patent with publication number CN223265827U, typically include a handle, mounting bracket, blade holder, and an adjustable-angle blade structure. In actual use, such cutters need to enter the material from one end and continuously cut to the other end to complete the cutting operation. If the blade is pressed down directly into the material from above, it is easy to cause indentations on the material surface, affecting the quality of the finished product. If the blade is lifted during the cutting process, it is easy to scrape the material due to the blade's tilted position, resulting in "material snagging," which not only affects cutting efficiency but may also damage the material or the blade. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a pneumatic angled cutter that can smoothly cut into and out of the material at an angle from any displacement, effectively avoiding the problems of cutter breakage, material indentation, and material snagging when lifting the cutter midway, thereby improving cutting efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a pneumatic bevel cutter, comprising: a cutter cylinder, a cutter mounting plate connected to the lower end of the cutter cylinder, a first cutter holder slidably fitted on the cutter mounting plate, and a first blade disposed on the first cutter holder; a reciprocating drive is disposed inside the cutter cylinder, the reciprocating drive is connected to the first cutter holder, and the reciprocating drive drives the first cutter holder to move obliquely back and forth, so that the first blade extends obliquely to insert into the material or retracts obliquely to detach from the material.

[0005] Preferably, the tool mounting plate is also obliquely slidably fitted with a second tool holder, on which a second blade is provided. The first tool holder and the second tool holder are slidably connected to a connecting slide rod. The reciprocating drive is connected to the connecting slide rod, so that when the reciprocating drive moves back and forth, it drives the first blade and the second blade to move closer to each other and extend into the material or move away from each other and detach from the material.

[0006] Preferably, a first slide rail and a second slide rail are obliquely mounted on the tool mounting plate, a first slider that slides and engages with the first slide rail is mounted on the first tool holder, and a second slider that slides and engages with the second slide rail is mounted on the second tool holder.

[0007] Preferably, the tool mounting plate is provided with a first sliding plate and a second sliding plate. The first sliding plate and the second sliding plate are respectively provided with a first sliding track and a second sliding track arranged obliquely. A first limiting groove is provided in the first sliding track and a second limiting groove is provided in the second sliding track. A first limiting block extends from the first tool holder and slides into the first limiting groove and slides with the first limiting groove. The first tool holder slides with the first sliding track through the first limiting block. A second limiting block extends from the second tool holder and slides with the second limiting groove. The second tool holder slides with the second limiting groove through the second limiting block.

[0008] Preferably, the reciprocating drive is a cylinder, and a slip ring is installed at the upper end of the cutter barrel. The reciprocating drive is connected to the slip ring, and the slip ring is connected to compressed gas to drive the reciprocating drive.

[0009] Preferably, the air slip ring is connected to a first air inlet head and a first air outlet head. One end of the first air inlet head is connected to compressed gas, and the other end of the first air inlet head is connected to the air inlet of the reciprocating drive component. One end of the first air outlet head is connected to the air outlet of the reciprocating drive component, and the other end of the first air outlet head is connected to the outside.

[0010] Preferably, the cutter barrel has a fastening hole, through which the screw is connected to the reciprocating drive component, thereby fixing the position of the reciprocating drive component in the cutter barrel.

[0011] Preferably, the reciprocating drive is connected to a control lever, which extends through the air ring, thereby facilitating the user to adjust the position of the reciprocating drive via the control lever.

[0012] Preferably, a first tool holder is provided with a first tool clip, and a first blade is disposed in the first tool clip; a second tool holder is provided with a second tool clip, and a second blade is disposed in the second tool clip.

[0013] Preferably, a pressure plate is connected to the tool mounting plate, and a pressure roller is floatingly connected to the pressure plate, which is used to press the material.

[0014] Preferably, a locking screw is slidably connected to the pressure plate, the locking screw is connected to a pressure roller bracket, the pressure roller is rotatably connected to the pressure roller bracket, and a spring is sleeved on the locking screw, with the two ends of the spring abutting against the pressure plate and the pressure roller bracket respectively.

[0015] Preferably, the piston rod of the reciprocating drive is connected to the connecting slide rod via a connector. The connector is provided with a mounting block, and a third blade holder is vertically provided on the mounting block. A third blade is vertically mounted on the third blade holder.

[0016] The beneficial effects of this invention are as follows: By setting up a slanted sliding fit tool holder and a slanted advance and retraction structure driven by a reciprocating drive, the technical problems of traditional slanted cutters easily producing indentations when pressed down and easily causing material snagging when lifted midway are effectively solved. This device enables the blade to quickly and smoothly cut into and exit the material at an angle, protecting the surface quality of the material and avoiding abnormal interference between the tool and the material, significantly improving the reliability of the cutting process and the yield rate. At the same time, the design of a double tool holder and a V-shaped symmetrical blade arrangement can efficiently complete the cutting of complex shapes such as V-grooves in a single stroke, greatly improving processing efficiency. In addition, the integrated air slip ring structure ensures the continuous stability of the air path when the tool body rotates, while the floating pressure material further ensures the adaptability of material flattening under different working conditions, making the entire system flexible, stable, and highly efficient.

[0026] Example: refer to Figures 1-3 A pneumatic beveling cutter includes: a cutter cylinder 1, with a cutter mounting plate 12 connected to its lower end. A first cutter holder 2 is obliquely slidably fitted onto the cutter mounting plate 12, and a first blade 21 is mounted on the first cutter holder 2. The first blade 21 can be mounted in the first cutter holder 22 by mounting a first cutter clamp 22 on the first cutter holder 2. A reciprocating drive is screwed into the cutter cylinder 1 and connected to the first cutter holder 2. The reciprocating drive drives the first cutter holder 2 to move obliquely back and forth, causing the first blade 21 to extend obliquely to insert into the material or retract obliquely to disengage from the material. This allows for cutting of the material even when the first blade 21 is above the material, by quickly cutting into the material at an oblique angle rather than forcibly pressing it in, avoiding indentations on the material surface. Furthermore, even if the first blade 21 is lifted midway, it can be pulled out obliquely along the cutting edge, avoiding scratching the material and preventing material snagging. This prevents damage to both the material and the blade.

[0027] refer to Figures 1-3To improve cutting efficiency, especially when cutting V-grooves, if only the first blade 21 is available, the blade needs to travel a similar distance again to cut the V-groove into the material. A second blade holder 3 is also obliquely slidably fitted onto the tool mounting plate 12. The second blade 31 is mounted on the second blade holder 3, and a second blade clip 32 is mounted on the second blade holder 3, with the second blade 31 installed in the second blade clip 32.

[0028] refer to Figures 1-3 The first blade 21 and the second blade 31 are arranged in a V-shape. The first tool holder 2 and the second tool holder 3 are slidably connected to a connecting slide rod 5. The piston rod of the reciprocating drive is connected to the connecting slide rod 5 through a connecting piece 51. Thus, when the reciprocating drive moves back and forth, it drives the first blade 21 and the second blade 31 to move closer to each other and insert into the material, or to move away from each other and detach from the material. Thus, the required V-groove can be machined on the material in one stroke.

[0029] refer to Figure 1 and Figure 2 Regarding the method by which the first tool holder 2 and the second tool holder 3 slide obliquely on the tool mounting plate 12, the first method is as follows: a first slide rail 61 and a second slide rail 71 are obliquely mounted on the tool mounting plate 12; a first slider that slides in cooperation with the first slide rail 61 is mounted on the first tool holder 2, thereby achieving an oblique sliding cooperation between the first tool holder 2 and the tool mounting plate 12. A second slider that slides in cooperation with the second slide rail 71 is mounted on the second tool holder 3, thereby achieving an oblique sliding cooperation between the second tool holder 3 and the tool mounting plate 12.

[0030] refer to Figure 1 and Figure 3 The second method involves bolting a first sliding plate 62 and a second sliding plate 72 onto the tool mounting plate 12. The first sliding plate 62 and the second sliding plate 72 are respectively provided with a first sliding track 63 and a second sliding track 73 arranged obliquely. A first limiting groove 64 is formed in the first sliding track 63, and a second limiting groove 74 is formed in the second sliding track 73. A first limiting block extends from the first tool holder 3, extending into and slidingly engaging with the first limiting groove 64. The first tool holder 2 slides with the first sliding track 63 via the first limiting block. Similarly, a second limiting block extends from the second tool holder 3, extending into and slidingly engaging with the second limiting groove 74. The second tool holder 3 slides with the second limiting groove 74 via the second limiting block.

[0031] refer to Figures 1-3The reciprocating drive is a cylinder. A slip ring 8 is mounted on the upper end of the cutter barrel 1, connecting the reciprocating drive to the slip ring 8. The slip ring 8 is connected to compressed gas to drive the reciprocating drive. The slip ring 8 is connected to a first air inlet 81 and a first air outlet 82. One end of the first air inlet 81 is connected to the compressed gas, and the other end is connected to the air inlet of the reciprocating drive via an air pipe. One end of the first air outlet 82 is connected to the air outlet of the reciprocating drive via an air pipe, and the other end is connected to the outside environment. The slip ring 8 ensures that even when the cutter barrel 1 rotates, the air pipe will not become entangled, guaranteeing the stable operation of the reciprocating drive.

[0032] refer to Figures 1-3 The tool barrel 1 has a fastening hole 11. A screw is connected to the reciprocating drive component through the fastening hole 11, thereby fixing the position of the reciprocating drive component in the tool barrel 1. The reciprocating drive component then controls the up-and-down movement of the tool mounting plate 12, thereby controlling the up-and-down movement of the first blade 21 and the second blade 31. The reciprocating drive component is connected to a control rod 41. One end of the control rod 41 extends through the air slip ring 8, allowing the user to adjust the position of the reciprocating drive component in the tool barrel 1 by moving the control rod 41 up and down. To prevent the blade from falling off when the air supply to the reciprocating drive component is suddenly cut off, a spring can be fitted onto the control rod 41.

[0033] refer to Figures 1-3 To improve the cutting effect and smoothness of the material by the blade, a pressure plate 9 is connected to the blade mounting plate 12. A pressure roller 91 is floatingly connected to the pressure plate 9. The pressure roller 91 is used to press the material, so that the material to be cut is flattened by the pressure roller 91 before the blade cuts. A locking screw 92 is slidably connected to the pressure plate 9. The locking screw 92 is connected to the pressure roller bracket 93. The pressure roller 91 is rotatably connected to the pressure roller bracket 93. A spring 94 is sleeved on the locking screw 92. The two ends of the spring 94 abut against the pressure plate 9 and the pressure roller bracket 93, respectively. Thus, the spring 94 forces the pressure roller 91 to always press on the material. Under the elastic support of the spring 94, the pressure roller 91 has a certain degree of floating, which makes it more suitable for materials of different thicknesses and in different environments.

[0034] refer to Figures 1-4To meet more cutting needs, optionally, the piston rod of the reciprocating drive is fixedly connected to the connecting slide rod 5 via a connector 51. A mounting block 511 is screwed onto the connector 51, and a third blade holder 512 is vertically screwed onto the mounting block 511. A third blade 513 is vertically mounted on the third blade holder 512, allowing for vertical cutting of the material using the third blade 513. A vertical screw hole 5111 can be made in the mounting block 511, through which the third blade holder 513 is screwed. This allows for easy adjustment of the height of the third blade holder 513 by controlling the degree of screwing in and out, thus coarsely adjusting the height of the third blade 513. The height of the third blade 513 can also be finely adjusted using the third blade holder 512 itself, which will not be elaborated further here.

[0035] Operation process: The pneumatic bevel cutter is assembled onto the external equipment. When it is necessary to cut the material, the external equipment lowers the pneumatic bevel cutter to the designated position. Then, the reciprocating drive presses down the connecting slide bar 5. With the cooperation of the obliquely arranged slider rail or slide plate, the first blade 21 and the second blade 31 are obliquely downward and move closer to each other, thus directly inserting into the material at an oblique angle. Under the drive of the external equipment, the material is cut. After completing one cutting stroke, the reciprocating drive pulls up the connecting slide bar 5. The first blade 21 and the second blade 31 obliquely separate from the material along the cut and move away from each other.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
