[0038] like Figure 1 , Figure 2 As shown, a semi-automatic corrugated pipe bevel cutting device includes a worktable 1, a lifting mechanism, a cutter assembly, a cutter guard 7, and an operating switch. The worktable 1 consists of multiple support legs and a support plate fixed on the support legs. The lifting mechanism includes a fixed component and a lifting component. The fixed component is mounted on the support plate, and the lifting component can move vertically up and down on the fixed component. The cutter assembly includes a cutter base 8 and a cutter 9. The cutter base 8 is fixed on the support plate located directly below the lifting mechanism, and the cutter 9 is connected to the lifting component. The lifting component drives the cutter 9 to move up and down, thereby cutting the corrugated pipe. The cutter guard 7 surrounds the cutter assembly to isolate the operator's hands from the cutter 9. The operating switch is connected in series in the circuit of the lifting mechanism to start and stop the lifting mechanism.

[0039] The following provides a further explanation of the specific structure of the aforementioned tool holder.

[0040] The tool base 8 adopts a two-section structure, consisting of symmetrically arranged U-shaped seats. A vertical gap I is left between the two U-shaped seats, and the cutting blade of the tool 9 can be inserted into the gap I to guide the cutting blade to move vertically.

[0041] In a further embodiment, a boss 12 is provided in the middle area of ​​the support plate, and two U-shaped seats are fixed to the boss 12 by fasteners, with a horizontal gap II between the fixed U-shaped seats and the boss 12.

[0042] In a further embodiment, a pad 13 is provided between the boss 12 and the U-shaped seat, and the fastener is a threaded post 14. The bottom plate of the U-shaped seat is provided with a through hole, and the boss 12 is provided with a threaded hole arranged coaxially with the through hole. After the threaded post 14 passes through the through hole, it is screwed into the threaded hole to fix the boss 12 and the U-shaped seat together.

[0043] In a further embodiment, a threaded post 14 is provided on each side of the base plate of the U-shaped seat. A guide post is installed on the base plate of the U-shaped seat in the area between the two fasteners. The guide post and one of the threaded posts 14 extend from the base plate of the U-shaped seat to form an oblique insertion port facing the blade. The bellows extends from the oblique insertion port to the underside of the blade for oblique cutting.

[0044] A further design involves a guide post movably connected to the base plate of the U-shaped seat. By adjusting the position of the guide post, the width of the oblique insertion port can be changed, thereby accommodating corrugated pipes of different diameters.

[0045] It should be noted that the guide post is preferably a magnetic post, which is attached to the base plate of the U-shaped seat and can be moved freely on the base plate of the U-shaped seat, thereby changing the distance between it and the fastener. Since the guide post is a separate component, it is not shown in the attached drawings.

[0046] The following provides a further explanation of the specific structure of the aforementioned cutting tool.

[0047] The cutting tool 9 consists of a blade and a clamp, which are connected together by a detachable component. The clamp is connected to a lifting component.

[0048] It should be noted that the blade and the clamp are fixed together by multiple screws, and the clamp and the lifting component are fixed together by screws.

[0049] The following provides a further explanation of the specific structure of the aforementioned operating switch.

[0050] The operating switches include a key switch 4, foot valve I 6, and foot valve II 10 connected in series; foot valve I 6 and foot valve II 10 are connected by a normally closed circuit and an intermittently closed circuit to prevent operator error during cutting.

[0051] In a further embodiment, the operating switch also includes an emergency stop switch 5 connected in series with the key switch 4, foot valve I 6, and foot valve II 10.

[0052] The following provides a further explanation of the specific structure of the aforementioned tool guard.

[0053] The tool guard 7 consists of a guardrail 15 fixed on the tool base 8 and a transparent cover connected to the guardrail 15; the transparent cover has an insertion port for easy insertion of the bellows.

[0054] The following provides a further explanation of the specific structure of the aforementioned lifting mechanism.

[0055] The lifting mechanism consists of a cylinder bracket 2 as a fixed component and a cylinder 3 as a lifting component. The cylinder bracket 2 is fixed on the support plate, and the cylinder 3 is mounted on the cylinder bracket 2. A cylinder triplet 11 is installed on the support leg to connect the main air circuit and the cylinder 3.

[0056] As can be seen from the above, this utility model provides a semi-automatic corrugated pipe bevel cutting device, which achieves the following functions and effects:

[0057] Workbench 1 is used to integrate the various parts into a whole and to serve as an overall support.

[0058] The cylinder bracket 2 is used to ensure that the cylinder shaft of the cylinder 3 extends and retracts in the vertical direction, while preventing it from rotating and ensuring the stability of the extension and retraction.

[0059] Cylinder 3 is installed in cylinder bracket 2. When cylinder 3 extends or retracts, it drives the cutter 9 to reciprocate to achieve cutting.

[0060] Key switch 4 is used to control the circuit on / off of the entire device.

[0061] Emergency stop switch 5 allows all operations to be stopped by pressing the button at the top.

[0062] Foot valve I6 and foot valve II10 are used in series. Foot valve I6 can be normally closed, and foot valve II10 can be continuously stepped on to open and close the air circuit to complete the cutting operation. Alternatively, foot valve II10 can be normally closed, and foot valve I6 can be continuously touched by the side leg to open and close the air circuit to complete the cutting operation. Both methods can avoid operator error during cutting.

[0063] The tool guard 7 is used to isolate the operator's hands outside the cylinder's extension and retraction range to avoid safety hazards.

[0064] The tool base 8 adopts a two-section structure with a certain gap in the middle and on both sides of the two sections. This allows the tool base to block the blade and make it fall into the gap, and run along the designated trajectory. At the same time, it avoids the blade from colliding with the surrounding area of ​​the tool base, which could cause the blade to break and create a safety hazard.

[0065] The cutting tool 9 consists of a blade and a clamp. The blade and the clamp are fixed together by multiple screws, and the clamp and the cylinder 3 are fixed together by screws. The blade can be replaced by removing the screws.

[0066] The pneumatic triplet 11 is used to connect the main air circuit to the cylinder 3 in this device.

[0067] In summary, this invention uses a solenoid valve to control the up-and-down movement of a cylinder, and employs a combination of blades, clamps, and a cutter base for limiting movement, to achieve semi-automatic, high-efficiency cutting of corrugated pipe bevels. After use, this invention can replace manual cutting of corrugated pipes, solving problems such as high labor intensity, low efficiency, and safety hazards associated with manual cutting.

[0068] Numerous specific details are set forth in the specification provided herein. However, it will be understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
