Description

Technical Field

[0001] This application relates to the field of double-wall corrugated pipes, and more particularly to a cutting device for double-wall corrugated pipes. Background Technology

[0002] Double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. It is commonly used in water supply, drainage, sewage discharge and other applications. It features light weight, low drainage resistance and high compressive strength.

[0003] Currently, Chinese utility model patent CN220389575U discloses a cutting device for HDPE double-wall corrugated pipes, including a base. The base has vertically upward-facing sidewalls on both sides, and longitudinal guide rails are installed on the outer sides of both sidewalls. The output end of the longitudinal guide rails is provided with a horizontally mounted cutting fixing table. A clamping structure that can be linearly adjusted and clamped is centrally located on the upper surface of the base. The corrugated pipe is clamped in the clamping structure. The horizontal guide rails can drive the clamping table to move laterally. It is compatible with a flexible saw blade that can be adjusted in angle and height, enabling the corrugated pipe to be cut in multiple directions. Therefore, it can meet different cutting and processing needs, thus effectively solving the problem of insufficient flexibility in corrugated pipe cutting and processing, which makes it difficult to meet different processing requirements.

[0004] When cutting with only a soft saw blade, the double-walled corrugated pipe is under unilateral stress. During the cutting process, the uneven circumferential stress on the double-walled corrugated pipe is prone to deformation, and the flatness of the cut end face is not high. Utility Model Content

[0005] In order to ensure that the double-walled corrugated pipe is subjected to uniform circumferential force during cutting, thereby improving the flatness of the rear end face of the double-walled corrugated pipe after cutting, this application provides a cutting device for double-walled corrugated pipe.

[0006] This application provides a cutting device for double-walled corrugated pipes, which adopts the following technical solution:

[0007] A cutting device for a double-walled corrugated pipe includes a frame, a cutting assembly, and a clamping assembly. The cutting assembly includes a cutting frame, a plurality of cutting blades, and a driving component. The cutting frame is mounted on the frame and has a placement hole. The cutting blades are circumferentially distributed along the axis of the placement hole and are rotatably connected to the frame. The driving component is used to drive the plurality of cutting blades to move toward the axis of the placement hole. The clamping assembly is used to keep the corrugated pipe coaxial with the placement hole.

[0008] By adopting the above technical solution, the clamping component is used to clamp the corrugated pipe, and the cutting component is used to cut the corrugated pipe. During the cutting process, the operator drives several cutting blades to rotate simultaneously in the direction of the placement hole. The cutting blades can cut the clamped corrugated pipe. Because there are several cutting blades and the cutting blades move at the same time, the circumferential force of the corrugated pipe is uniform during the cutting process, the deformation of the corrugated pipe is reduced, and the flatness of the cut end face of the corrugated pipe is high.

[0009] Optionally, the driving component includes a rotating ring and a driving cylinder. The rotating ring is coaxially arranged with the placement hole and rotatably connected to the cutting frame. The rotating ring has a plurality of sliding grooves, each of which corresponds to a plurality of cutting blades. Each cutting blade is provided with a sliding column, which is located in the sliding groove. The driving cylinder is used to drive the rotating ring to rotate.

[0010] By adopting the above technical solution, when the corrugated pipe needs to be cut, the operator starts the drive cylinder, which drives the rotating ring to rotate. The sliding column on the cutting blade slides in the sliding groove, and the cutting blade can rotate along the rotation axis of the cutting blade on the frame. The cutting blade approaches the corrugated pipe until it is cut. The drive component has a simple structure and is easy to operate.

[0011] Optionally, the clamping assembly includes a clamping ring, a plurality of clamping blocks, and a driving member. The clamping ring is disposed on the frame and is coaxially disposed with the placement hole. The plurality of clamping blocks are slidably connected to the clamping ring. The driving member is used to drive the clamping blocks closer to the axis of the clamping ring.

[0012] By adopting the above technical solution, the clamping assembly is used to clamp the corrugated pipe, reducing the displacement of the corrugated pipe during the cutting process, thereby improving the quality of the corrugated pipe after cutting. The operator passes the corrugated pipe through the clamping ring, and the drive component moves the clamping block close to the corrugated pipe. Since several clamping blocks are distributed along the axis of the placement hole, several clamping blocks can make the corrugated pipe and the placement hole coaxial, so that several cutting blades are in a state of uniform force when cutting the corrugated pipe.

[0013] Optionally, the driving component includes a driving ring, a driving gear ring, a driving motor, and a driving gear. The driving ring is coaxially arranged with the clamping ring and is rotatably connected to the clamping ring. An Archimedean spiral groove is formed on the end face of the driving ring, and the clamping block slides into the Archimedean spiral groove. The driving gear ring is disposed on the driving ring, and the driving gear is rotatably connected to the frame. The driving gear meshes with the driving gear ring, and the driving motor is used to drive the driving gear to rotate.

[0014] By adopting the above technical solution, the motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the ring to rotate. The Archimedes plane spiral groove on the ring cooperates with the clamping block, and the clamping block can move along the radial direction of the clamping ring until the clamping block clamps the bellows. The drive component has a simple structure and is easy for operators to operate.

[0015] Optionally, the clamping assembly further includes auxiliary components and linkage components. The auxiliary components include an auxiliary ring and several auxiliary blocks. The auxiliary ring is slidably connected to the frame along the axial direction of the placement hole. The several auxiliary blocks are circumferentially distributed along the axial direction of the auxiliary ring. The auxiliary blocks are connected to the auxiliary ring along the radial sliding direction of the auxiliary ring. The linkage components are used to drive the auxiliary blocks to slide.

[0016] By adopting the above technical solution, some corrugated pipes are quite long. If they are held by the clamping blocks on the clamping component alone, the corrugated pipes will tilt under the action of gravity. The auxiliary component is used to assist in clamping the corrugated pipes, reduce the influence of the weight of the corrugated pipes, and improve the alignment of the axis of the corrugated pipes with the placement hole. The operator first places the corrugated pipes on the clamping ring and the auxiliary ring. The driving component causes the clamping blocks to clamp the corrugated pipes, and the linkage component drives the auxiliary blocks to clamp the corrugated pipes.

[0017] Optionally, the linkage component includes a linkage ring, a linkage tube, and a linkage column. The linkage ring is coaxially arranged with the auxiliary ring and is rotatably connected to the auxiliary ring. An Archimedean spiral groove is formed on the linkage ring, and the auxiliary block slides into the Archimedean spiral groove. The linkage column is parallel to the extension direction of the placement hole, and one end of the linkage column is disposed on the linkage ring. The linkage tube is sleeved on the linkage column and is disposed on the driving ring.

[0018] By adopting the above technical solution, the motor drives the gear to rotate, the gear drives the gear ring to rotate, the gear ring drives the ring to rotate, the ring drives the clamping block to slide along the radial direction of the clamping ring, and at the same time the ring drives the linkage tube to rotate along the axis of the ring, the linkage tube drives the linkage column to rotate, the linkage column drives the linkage ring to rotate, and the linkage ring drives the auxiliary block to move along the axis of the auxiliary ring through the Archimedes plane spiral groove until the auxiliary block clamps the bellows.

[0019] Optionally, the clamping assembly further includes an adjusting component for controlling the distance between the auxiliary ring and the clamping ring. The adjusting component includes an adjusting screw and an adjusting motor. The length direction of the adjusting screw is parallel to the sliding direction of the auxiliary ring. The adjusting screw is rotatably connected to the frame and threadedly connected to the auxiliary ring. The adjusting motor drives the adjusting screw to rotate.

[0020] By adopting the above technical solution, the outer wall of the bellows is a ring structure. The clamping block and the auxiliary block need to be engaged between adjacent ring structures. Since the bellows have various specifications, the operator can adjust the distance between the auxiliary ring and the clamping ring through the adjusting parts so that the clamping block and the auxiliary block can be engaged between adjacent ring structures. The adjusting motor drives the adjusting screw to rotate, and the adjusting screw drives the auxiliary ring to slide, thus changing the distance between the auxiliary ring and the clamping ring.

[0021] Optionally, the frame includes a base, a sliding frame, and a control component. The cutting assembly is disposed on the base, the sliding frame is slidably connected to the base along the axial direction of the placement hole, the clamping assembly is disposed on the sliding frame, and the control component includes a control screw and a control motor. The length direction of the control screw is parallel to the sliding direction of the sliding frame, the control screw is rotatably connected to the base, the control screw is threadedly connected to the base, and the control motor is used to drive the control screw to rotate.

[0022] By adopting the above technical solution, after the clamping assembly clamps the corrugated pipe, the operator can adjust the position of the corrugated pipe and the cutting assembly through the control components in order to control the length of the corrugated pipe cutting. The operator starts the control motor, which drives the control screw to rotate. The control screw drives the sliding frame to slide, and the sliding frame drives the cutting assembly to move closer to or away from the cutting assembly, thus realizing the cutting of corrugated pipes of different lengths.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Several cutting blades cut along the circumference of the corrugated pipe, so that the corrugated pipe is subjected to uniform force in the circumference, reducing the deformation of the corrugated pipe and improving the flatness of the corrugated pipe cut.

[0025] 2. The positions of the auxiliary ring and the clamping ring are adjustable, making the clamping assembly suitable for bellows of different specifications and improving the applicability of the equipment. Attached Figure Description
