Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing technology, and in particular to a follow-up rotary cutting device for corrugated pipe processing. Background Technology

[0002] Corrugated pipes on the market mainly consist of various types of pipe fittings, including metal corrugated pipes, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes, and metal flexible hoses. They are primarily used to compensate for pipeline thermal deformation, reduce vibration, and absorb pipeline settlement deformation, and are widely used in industries such as petrochemicals, instrumentation, aerospace, chemicals, power, water conservancy, and metallurgy. Corrugated pipes made of plastics and other materials play an irreplaceable role in media transportation, power wiring, machine tools, and home appliances.

[0003] To accommodate use on equipment in different industries and facilitate transportation, the length of the corrugated pipe needs to be specified. Therefore, the corrugated pipe needs to be cut into sections during processing. The traditional cutting method simply involves cutting the corrugated pipe around its perimeter with a cutting machine. This cutting method lacks effective restraint and support for the corrugated pipe on both sides of the cut end, resulting in poor cutting stability. Furthermore, the corrugated pipe needs to remain stationary during the cutting process, which severely affects its production and processing efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the traditional method of cutting corrugated pipes is simply to cut the corrugated pipe around the perimeter of the pipe using a cutting machine. This method does not provide effective limiting and support for the corrugated pipe on both sides of the cutting end, resulting in poor cutting stability. Moreover, the corrugated pipe needs to remain stationary during the cutting process, which seriously affects its production and processing efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a follow-up rotary cutting device for corrugated pipe processing, including a main frame, a first electrically controlled conveyor belt and a second electrically controlled conveyor belt installed on the main frame, a sliding translation guide seat installed on the main frame between the first electrically controlled conveyor belt and the second electrically controlled conveyor belt, an electrically controlled cutting machine movably mounted on the upper end of the sliding translation guide seat, a flip-type lower side sleeve arm movably mounted on both sides of the electrically controlled cutting machine, a sliding upper side sleeve arm slidably mounted on the outer surface of the flip-type lower side sleeve arm, and an electric drive wheel installed on the lower end of the outer surface of the flip-type lower side sleeve arm and the upper end of the outer surface of the sliding upper side sleeve arm.

[0006] The main frame is fixedly equipped with side sliding guide rods on both sides between the first and second electrically controlled conveyor belts. The sliding translation guide seat is slidably assembled with the side sliding guide rods by being sleeved on them.

[0007] Both sides of the main frame are fixedly equipped with side-mounted synchronous push rods for controlling the sliding translation guide seat.

[0008] The upper surface of the sliding translation guide seat is equipped with an electrically controlled lifting guide rail.

[0009] The electrically controlled cutting machine includes an arc-shaped mounting base that is slidably mounted inside the guide groove at the upper end of the electrically controlled lifting guide rail, and an electrically controlled cutting blade that is mounted on the upper end of the arc-shaped mounting base via an upper bracket.

[0010] Both sides of the arc-shaped mounting base are fixedly fitted with lateral mounting frames for mounting the flip-type lower sleeve arm, and the lower outer side of the lateral mounting frame is fitted with a side-mounted adjusting support rod for controlling the flip-type lower sleeve arm to flip.

[0011] A side-mounted storage frame for storing the sliding side upper arm is fixed on the outer surface of the flip-type lower side arm, and a side upper adjustment motor for controlling the sliding side upper arm is installed on the outer surface of the side-mounted storage frame.

[0012] Lateral isolation covers are fixedly mounted on both sides of the arc-shaped mounting base, and a side-mounted dust collection box with a built-in centrifugal air pump is fixedly mounted on the outer side of the lateral isolation cover.

[0013] The electrically controlled lifting guide rail includes a scissor lift mounted on a sliding translation guide seat and a translation guide rail mounted on the upper end of the scissor lift.

[0014] The sliding translation guide seat has a guide limit rod for improving the stability of the translation guide rail.

[0015] The beneficial effects of this invention are:

[0016] (1) The following rotary cutting device for bellows processing of the present invention adopts an external surrounding structure design, which can be fixed on the outside of the bellows and then cut around the bellows, thereby improving the cutting accuracy.

[0017] (2) The entire equipment is directly integrated into the conveying equipment, and the corrugated pipe on the conveying equipment can be directly operated, greatly improving processing efficiency and functional integration.

[0018] (3) By controlling the cutting mechanism through speed-synchronous operation, synchronous operation can be ensured while cutting, thereby ensuring that the processing efficiency of the corrugated pipe remains unchanged.

[0019] (4) The equipment is fitted onto the outside of the corrugated pipe by bottom lifting, side flipping and telescopic methods, which makes it easy to separate and store when not in use;

[0020] (5) The electric drive wheel located at the lower end of the outer side of the flip-type lower sleeve arm and the upper end of the outer side of the sliding upper sleeve arm can drive the entire cutting device to run around the bellows. By rotating along the grooves on both sides of the cutting surface, not only can the guiding function be guaranteed, but also the cutting surface can be limited on both sides, thereby improving the cutting stability.

[0021] (6) By installing an electrically controlled lifting guide rail on the upper surface of the sliding translation guide seat, rotational stability and guidance can be guaranteed, while quickly separating from the bellows;

[0022] (7) By fixing lateral isolation covers on both sides of the arc-shaped mounting base and fixing a side-mounted dust collection box with a built-in centrifugal air pump on the outer side of the lateral isolation cover, the isolation and dust extraction during the cutting process can be improved.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Figure 1 , Figure 2 and Figure 3The illustrated follow-up rotary cutting device for corrugated pipe processing includes a main frame, a first electrically controlled conveyor belt 2 and a second electrically controlled conveyor belt 3 mounted on the main frame 1. A sliding translation guide seat 4 is installed on the main frame 1 between the first electrically controlled conveyor belt 2 and the second electrically controlled conveyor belt 3. An electrically controlled cutting machine 5 is movably mounted on the upper end of the sliding translation guide seat 4. A flip-type lower side sleeve arm 6 is movably mounted on both sides of the electrically controlled cutting machine 5. A sliding upper side sleeve arm 7 is slidably mounted on the outer surface of the flip-type lower side sleeve arm 6. Electric drive wheels 8 are installed on the lower end of the outer surface of the flip-type lower side sleeve arm 6 and the upper end of the outer surface of the sliding upper side sleeve arm 7.

[0030] The first electrically controlled conveyor belt 2, the second electrically controlled conveyor belt 3, and the electric drive wheel 8 are all existing technologies. The first electrically controlled conveyor belt 2 and the second electrically controlled conveyor belt 3 drive the corrugated pipe to move and transport horizontally on the main frame 1. The electric drive wheel 8 is inserted into the grooves on both sides of the cut surface of the corrugated pipe for guidance and driving.

[0031] To facilitate translational guidance, side-mounted sliding guide rods 9 are fixedly mounted on both sides of the main frame 1 between the first electrically controlled conveyor belt 2 and the second electrically controlled conveyor belt 3. The sliding translational guide seat 4 is slidably assembled with the side-mounted sliding guide rods 9 by being sleeved on them.

[0032] To facilitate lateral translation adjustment, side-mounted synchronous push rods 10 for controlling the sliding translation guide seat 4 are fixedly mounted on both sides of the main frame 1.

[0033] The side-mounted synchronous push rod 10 controls the sliding translation guide seat 4 to move and adjust along the side-mounted sliding guide rod 9 by telescoping.

[0034] To facilitate bottom lifting and guiding, an electrically controlled lifting guide rail 11 is installed on the upper surface of the sliding translation guide seat 4.

[0035] To facilitate cutting, the electronically controlled cutting machine 5 includes an arc-shaped mounting base 51 that is slidably mounted inside the guide groove at the upper end of the electronically controlled lifting guide rail 11, and an electronically controlled cutting blade 52 that is mounted on the upper end of the arc-shaped mounting base 51 via an upper bracket.

[0036] The electrically controlled cutting blade 52 consists of a side-mounted drive motor installed in the arc-shaped cutting groove inside the arc-shaped mounting base 51 and a cutting blade mounted on the lateral drive shaft of the side-mounted drive motor.

[0037] To facilitate lateral tilting adjustment, both sides of the arc-shaped mounting base 51 are fixedly fitted with lateral mounting frames 53 for mounting the tilting side lower sleeve arm 6, and the lower ends of the outer sides of the lateral mounting frames 53 are fitted with side-mounted adjusting struts 54 for controlling the tilting of the tilting side lower sleeve arm 6.

[0038] The side-mounted adjustable support rod 54 is adjusted by tilting and rotating the lower side sleeve arm 6 through telescopic control.

[0039] To facilitate sliding extension, a side storage frame 12 for storing the sliding side upper arm 7 is fixed on the outer side surface of the flip-type side lower arm 6. A side upper adjustment motor 13 for controlling the sliding side upper arm 7 is installed on the outer side surface of the side storage frame 12.

[0040] An arc-shaped adjustment groove is provided on the outer surface of the sliding upper side sleeve 7. The upper side adjustment motor 13 is connected to the sliding upper side sleeve 7 through an adjustment gear on the adjustment shaft that meshes with the arc-shaped adjustment groove, thereby lifting the sliding upper side sleeve 7 to slide and adjust inside the side storage frame 12. When the side adjustment support rod 54 extends and controls the flipping lower side sleeve 6 to flip to both sides of the bellows, the electric drive wheel 8 at the lower end of the outer side of the flipping lower side sleeve 6 and the upper end of the outer side of the sliding upper side sleeve 7 presses against the grooves on both sides of the bellows. At this time, the upper side adjustment motor 13 drives the sliding upper side sleeve 7 to rotate along the guide grooves on both sides of the bellows cutting surface, thereby rotating circumferentially along the bellows cutting surface, thus cutting the bellows around one circumference.

[0041] To facilitate dust isolation and extraction, lateral isolation covers 14 are fixedly mounted on both sides of the arc-shaped mounting base 51, and a side-mounted dust collection box 16 with a built-in centrifugal air pump 15 is fixedly mounted on the outer side of the lateral isolation cover 14.

[0042] The centrifugal vacuum pump 15 is existing technology. It draws dust into the side-mounted dust collection box 16 through the dust extraction hole on the side isolation cover 14, which facilitates side dust collection during cutting. The centrifugal vacuum pump 15 operates synchronously with the electrically controlled cutting blade 52.

[0043] To facilitate lifting, the electrically controlled lifting guide rail 11 includes a scissor lift 111 mounted on a sliding translation guide seat 4 and a translation guide rail 112 mounted on the upper end of the scissor lift 111.

[0044] The scissor lift 111 is existing technology. It controls the lateral extension and retraction by extending and retracting the electrically controlled strut located on the sliding translation guide seat 4, thereby adjusting the longitudinal height of the translation guide rail 112.

[0045] To improve the lateral stability of the translation guide rail 112 during lifting, the sliding translation guide seat 4 has a guide limit rod 17 for improving the stability of the translation guide rail 112.

[0046] The translation guide rail 112 has arc-shaped limiting grooves on both sides that cooperate with the guide limiting rod 17. The guide limiting rod 17 slides with the translation guide rail 112 by inserting into the arc-shaped limiting groove, thereby improving the stability of the translation guide rail 112 in different positions.

[0047] Working principle: The corrugated pipe moves horizontally from the first electrically controlled conveyor belt 2 to the second electrically controlled conveyor belt 3. When cutting is required, the side-mounted synchronous push rod 10 extends and retracts to control the sliding translation guide seat 4 to move and adjust along the side-mounted sliding guide rod 9. The sliding translation guide seat 4 moves horizontally at the same speed at the bottom of the corrugated pipe. At this time, the side-mounted adjusting support rod 54 extends and retracts to control the flipping side lower sleeve arm 6 to flip and adjust. Then, the side upper adjusting motor 13 rotates to drive the sliding side upper sleeve arm 7 to rotate along the guide grooves on both sides of the corrugated pipe cutting surface. At this time, the electric drive wheel 8 and the electrically controlled cutting machine 5 are started, thus rotating circumferentially along the corrugated pipe cutting surface, thereby cutting the corrugated pipe in one revolution. After completion, the above operation is reversed, and then the side-mounted synchronous push rod 10 drives the sliding translation guide seat 4 to slide and reset.

[0048] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
