Description

Technical Field

[0001] This utility model relates to the field of profile cutting machine technology, specifically a profile cutting machine capable of cutting rounded chamfers. Background Technology

[0002] Profile cutting machines, also known as abrasive wheel saws, are suitable for use in construction, hardware, petrochemical, machinery and metallurgy, and water and electricity installation industries. They are commonly used equipment for cutting materials such as metal square and flat tubes, square and flat steel, I-beams, channel steel, carbon steel, and round tubes. Profile cutting machines are suitable for sawing various irregularly shaped metals such as aluminum, aluminum alloys, copper, copper alloys, non-metallic plastics, and carbon fiber. They are particularly suitable for sawing aluminum doors and windows, picture frames, PVC profiles, bakelite boards, aluminum extrusions, paper tubes, and profiles.

[0003] Utility model patent with authorization announcement number CN213701988U discloses a profile cutting machine. The utility model includes a base, a cutting mechanism mounted on the base, and a clamping mechanism mounted on the base. The base has a clearance groove for the cutting tool on the cutting mechanism to work. The clamping mechanism is located on one side of the clearance groove. A support frame is provided on the side of the base away from the clearance groove from the clamping mechanism. An extrusion plate is movably mounted on the support frame in the vertical direction. A driving mechanism is provided on the support frame to drive the extrusion plate to move in the vertical direction. This application can improve the cutting quality of the cutting machine.

[0004] While the aforementioned utility model can effectively improve the cutting quality of the cutting machine, in actual use, depending on the needs of different application scenarios, there may be situations where it is necessary to cut a rounded chamfer at one end of the profile, which the aforementioned utility model cannot cut. Therefore, we propose a profile cutting machine capable of cutting rounded chamfers. Utility Model Content

[0005] This invention provides a profile cutting machine capable of cutting rounded chamfers, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A profile cutting machine capable of cutting rounded chamfers includes a support base, with support feet welded to the four corners of the lower surface of the support base, a limit mechanism rotatably connected to the right side of the middle position of the upper surface of the support base, and an adjustment mechanism slidably connected to the left side of the upper surface of the support base. A cutting groove is provided on the right side of the upper surface of the support base, an installation hole for the limiting mechanism is provided at the middle right position of the upper surface of the support base, an installation groove is provided on the left side of the upper surface of the support base, and several limiting holes are provided on the upper surface area of ​​the support base near the installation groove.

[0007] As a preferred technical solution, the limiting mechanism includes a mounting rod rotatably connected in the mounting hole, a rotating disk welded to the lower end of the mounting rod, and a limiting base welded to the upper end of the mounting rod. Limiting plates are slidably connected to both sides of the upper surface of the limiting base, and a threaded rod is threadedly connected between the two limiting plates. An auxiliary plate is welded to the left end of the threaded rod.

[0008] This feature allows the rotating disk and mounting rod to work together to enable the limiting mechanism to rotate, allowing the angle of the profile to be adjusted according to cutting requirements, thus providing angle adjustment for chamfer cutting.

[0009] As a preferred technical solution, the mounting groove is arc-shaped, the limiting holes are also arc-shaped, and the arc center angle between two adjacent limiting holes is 5°. The center of the arc-shaped mounting groove overlaps with the center of the mounting hole and is close to the inner side of the mounting groove arc. The rotating disk is rotatably connected to the lower surface of the mounting hole.

[0010] This design, with its arc-shaped mounting groove and arc-shaped limiting holes, provides a path for the arc-shaped movement of the adjustment mechanism, facilitating the cutting of rounded chamfers at different angles.

[0011] As a preferred technical solution, a connecting plate is welded to the right end of the lower surface of the limiting plate. The connecting plate is threadedly connected to the threaded rod and slidably connected to the right side surface of the limiting base. Two threaded segments with opposite directions and equal pitch are opened at the left and right ends of the outer surface of the threaded rod.

[0012] This feature, with its connecting plate, makes the connection between the limiting plate and the threaded rod more secure, while ensuring that the limiting plate slides smoothly along the limiting base, preventing displacement during sliding that could affect the positioning accuracy of the profile.

[0013] As a preferred technical solution, the adjustment mechanism includes a baffle, an adjustment rod welded to the upper surface of the baffle, a clamping mechanism welded to the upper surface of the adjustment rod, and a positioning plate welded to the top of the side surface of the adjustment rod.

[0014] This feature allows the clamping mechanism to fix the profile in place for a second time, and together with the limiting mechanism, it further enhances the stability of the profile during the cutting process and reduces cutting errors.

[0015] As a preferred technical solution, a positioning hole is provided on the upper surface of the positioning plate, the size of which is the same as that of the limiting hole, and a pin is slidably connected inside the positioning hole.

[0016] This feature, with its consistent sized positioning and limiting holes, ensures that the pin can be smoothly inserted to secure the positioning plate to the support base, making operation simple and convenient.

[0017] As a preferred technical solution, the clamping mechanism includes a clamping base, a vertical support plate welded to the left side surface of the clamping base, and a clamping support plate welded to the upper surface of the vertical support plate. A clamping bolt is threaded onto the upper surface of the clamping support plate, and a clamping plate is rotatably connected to the lower end of the clamping bolt.

[0018] This feature allows the clamping plate to move up and down by rotating the clamping bolts, which can accommodate profiles of different thicknesses and clamp them in place, further expanding the equipment's adaptability to different profile specifications.

[0019] As a preferred technical solution, the upper surface of the clamping base and the upper surface of the limiting base are located in the same horizontal plane, and the adjusting mechanism can rotate from 0° to 90° around the limiting mechanism.

[0020] This setting ensures that the upper surfaces of both are on the same horizontal plane, guaranteeing that the profile remains horizontal after placement and avoiding deviations in the cutting angle due to tilting, thus ensuring the accuracy of the rounded chamfer cutting.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the cooperation of the limiting mechanism and the adjusting mechanism, the profile can be rotated by 5° with each cut. After multiple cuts, a rounded chamfer can be left at one end of the profile.

[0022] 2. The adjustment mechanism is fixed by a straight up-and-down pin, which can be easily and quickly fixed and unfixed, making it convenient for users to control the position of the adjustment mechanism. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-5 This embodiment provides a technical solution: A profile cutting machine capable of cutting rounded chamfers includes a support base 100, with support feet 200 welded to the four corners of the lower surface of the support base 100, a limit mechanism 300 rotatably connected to the right side of the middle position of the upper surface of the support base 100, and an adjustment mechanism 400 slidably connected to the left side of the upper surface of the support base 100. A cutting groove 110 is provided on the right side of the upper surface of the support base 100. An installation hole 120 for mounting the limiting mechanism 300 is provided at the middle right position of the upper surface of the support base 100. An installation groove 130 is provided on the left side of the upper surface of the support base 100. Several limiting holes 140 are provided on the upper surface area of ​​the support base 100 near the installation groove 130. Through the above mechanism, during the profile cutting process, the angle between the profile being cut and the cutting blade can be adjusted by continuously adjusting the position of the adjusting mechanism 400. Through multiple 5° moving cuts, an arc-shaped chamfer cutting trajectory can be formed at one end of the profile.

[0026] Furthermore, such as Figure 2 and Figure 3As shown, the limiting mechanism 300 includes a mounting rod 310 rotatably connected to the mounting hole 120, a rotating disk 320 welded to the lower end of the mounting rod 310, and a limiting base 330 welded to the upper end of the mounting rod 310. Limiting plates 340 are slidably connected to both sides of the upper surface of the limiting base 330. A threaded rod 350 is threaded between the two limiting plates 340. An auxiliary plate 360 ​​is welded to the left end of the threaded rod 350. The movement of the limiting plates 340 on both sides can be controlled by the threaded rod 350. The mounting groove 130 is arc-shaped, and the limiting holes 140 are also arc-shaped. The arc angle between two adjacent limiting holes 140 is 5°. The center of the arc-shaped mounting groove 130 overlaps with the center of the mounting hole 120 and is close to it. On one side of the mounting groove 130, the rotating disk 320 is rotatably connected to the lower surface of the mounting hole 120, so that the rotating disk 320 can rotate on the surface of the support base 100 that is attached to the lower surface of the mounting hole 120, so that the limiting mechanism 300 can rotate as a whole. A connecting plate is welded to the right end of the lower surface of the limiting plate 340. The connecting plate is threadedly connected to the threaded rod 350 and slidably connected to the right side surface of the limiting base 330. The outer surface of the threaded rod 350 has two threaded sections with opposite directions and equal pitch at both ends. When the threaded rod 350 is rotated by the auxiliary plate 360, the two limiting plates 340 at both ends of the threaded rod 350 can move towards each other or away from each other at the same time, which is convenient for clamping the profile.

[0027] In this embodiment, as Figure 4 As shown, the adjustment mechanism 400 includes a baffle 410, an adjustment rod 420 welded to the upper surface of the baffle 410, a clamping mechanism 430 welded to the upper surface of the adjustment rod 420, and a positioning plate 440 welded to the top of the side surface of the adjustment rod 420. The positioning plate 440 has a positioning hole on its upper surface. The size of the positioning hole is the same as that of the limiting hole 140. A pin is slidably connected in the positioning hole. The positioning plate 440 can be fixed by the pin, so that the entire adjustment mechanism 400 can be fixed in the mounting groove 130.

[0028] In this embodiment, as Figure 5 As shown, the clamping mechanism 430 includes a clamping base 431, a vertical support plate 432 welded to the left side surface of the clamping base 431, and a clamping support plate 433 welded to the upper surface of the vertical support plate 432. A clamping bolt 435 is threadedly connected to the upper surface of the clamping support plate 433. A clamping plate 434 is rotatably connected to the lower end of the clamping bolt 435. By controlling the clamping plate 434 to move downward through the clamping bolt 435, the profile can be limited and fixed. The upper surface of the clamping base 431 and the upper surface of the limiting base 330 are located in the same horizontal plane. The adjusting mechanism 400 can rotate from 0° to 90° around the limiting mechanism 300.

[0029] In the specific use of the profile cutting machine capable of cutting rounded chamfers in this embodiment, the profile is first placed into the limiting mechanism 300 through the clamping mechanism 430. Then, by turning the auxiliary plate 360, the threaded rod 350 is controlled to rotate, causing the limiting plates 340 connected to the two ends of the threaded rod 350 to move towards each other, thus clamping and fixing the profile. Then, the clamping bolt 435 is turned to completely fix the profile through the positioning plate 440. After cutting the profile once, the pins inserted into the positioning plate 440 and the limiting hole 140 are removed. The adjusting mechanism 400 is controlled to move a certain distance in the mounting groove 130. When the positioning plate 440 and the second limiting hole 140 can be connected through the pins, the two are fixed. At this time, the adjusting mechanism 400 rotates the profile by 5°, and then cuts again. The above steps are repeated until the profile is in a vertical state and cannot be cut. Multiple cuts at 5° intervals can form a rounded chamfer at the cut end of the profile.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
