Description

Technical Field

[0001] The invention relates to the technical field of bellows processing, in particular to a follow-up rotating cutting device used for bellows processing. Background Art

[0002] The bellows on the market are mainly composed of metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes and metal hoses. It is a kind of pipe fitting mainly used to compensate for pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation. It is widely used in petrochemical, instrumentation, aerospace, chemical, electric power, water conservancy, metallurgy and other industries. Plastic and other materials of bellows have irreplaceable roles in media transportation, power threading, machine tools, home appliances and other fields.

[0003] In order to be used on equipment in different industries and facilitate transportation, there are certain requirements for the length of the corrugated pipe. Therefore, the length of the corrugated pipe needs to be cut into sections during processing. The traditional cutting method is simply to use a cutting machine to cut the corrugated pipe around the periphery of the pipe. This cutting method has poor cutting stability because there is no effective limit and support for the corrugated pipe on both sides of the cutting end, and the corrugated pipe needs to remain still during the cutting process, which seriously 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 cutting method of corrugated pipes is simply to use a cutting machine to cut the corrugated pipe around the periphery of the pipe. This cutting method has poor cutting stability because there is no effective limitation and support for the corrugated pipe on both sides of the cutting end, and the corrugated pipe needs to remain still 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 problems is: a follow-up rotating cutting device used for corrugated pipe processing, comprising 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 is installed on the main frame between the first electrically controlled conveyor belt and the second electrically controlled conveyor belt, an electrically controlled cutting machine is movably mounted on the upper end of the sliding translation guide seat, and flip-type side lower sleeve arms are movably mounted on both sides of the electrically controlled cutting machine, a sliding side upper sleeve arm is slidably mounted on the outer side surface of the flip-type side lower sleeve arm, and electric drive wheels are installed on the lower end of the outer side surface of the flip-type side lower sleeve arm and the upper end of the outer side surface of the sliding side upper sleeve arm.

[0006] Side sliding guide rods are fixedly mounted on both sides of the main frame between the first electrically controlled conveyor belt and the second electrically controlled conveyor belt, and the sliding translation guide seat is slidably mounted on the side sliding guide rods by being sleeved on the side sliding guide rods.

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

[0008] An electrically controlled lifting guide rail is installed on the upper surface of the sliding translation guide seat.

[0009] The electric-controlled cutting machine comprises an arc-shaped assembly seat which is slidably assembled inside the guide groove at the upper end of the electric-controlled lifting guide rail, and an electric-controlled cutting blade which is mounted on the upper end of the arc-shaped assembly seat through an upper end bracket.

[0010] The arc-shaped assembly seat has lateral mounting frames fixedly mounted on both sides for mounting the flip-type side lower sleeve arms, and the lower ends of the outer sides of the lateral mounting frames are mounted with lateral adjustment struts for controlling the flipping of the flip-type side lower sleeve arms.

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

[0012] Both side surfaces of the arc-shaped assembly seat are fixedly assembled with lateral isolation covers, and the outer side surface of the lateral isolation cover is fixedly assembled with a side dust collecting box with a built-in centrifugal air pump.

[0013] The electrically controlled lifting guide rail comprises a scissor-type lift installed on a sliding translation guide seat and a translation guide rail installed on the upper end of the scissor-type lift.

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

[0015] The beneficial effects of the present invention are:

[0016] (1) The follow-up rotary cutting device used for processing a corrugated pipe of the present invention adopts an external surrounding structure design, which can be fixed on the outside of the corrugated pipe and then cut along the periphery of the corrugated pipe, thereby improving the cutting accuracy;

[0017] (2) The entire equipment is directly integrated on the conveying equipment, and the bellows on the conveying equipment can be directly operated, which greatly improves the processing efficiency and functional integration;

[0018] (3) The cutting mechanism is controlled by running synchronously with the speed, which can ensure synchronous operation while cutting, thereby ensuring that the processing efficiency of the corrugated pipe remains unchanged;

[0019] (4) The equipment is placed on the outside of the bellows by lifting the bottom, flipping the sides, and telescoping, making it easy to separate and store when not in use;

[0020] (5) The electric drive wheels located at the lower end of the outer side surface of the flip-type side lower sleeve arm and the upper end of the outer side surface of the sliding side upper sleeve arm can drive the entire cutting device to run along the corrugated pipe. By rotating along the grooves on both sides of the cutting surface, not only can the guiding performance be ensured, but also the two sides of the cutting surface can be limited, 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, the rotation stability and guidance can be ensured, and the bellows can be quickly separated;

[0022] (7) By fixing lateral isolation covers on both side surfaces of the arc-shaped assembly seat and fixing a side dust collecting box with a built-in centrifugal vacuum pump on the outer side surface of the lateral isolation covers, the isolation and dust extraction performance during the cutting process can be improved.

[0029] Figure 1 , Figure 2 and Figure 3A follow-up rotating cutting device used for corrugated pipe processing is shown, comprising a main frame, a first electrically-controlled conveyor belt 2 and a second electrically-controlled conveyor belt 3 installed 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, and flip-type side lower sleeve arms 6 are movably mounted on both sides of the electrically-controlled cutting machine 5, a sliding side upper sleeve arm 7 is slidably mounted on the outer side of the flip-type side lower sleeve arm 6, and an electric drive wheel 8 is installed on the lower end of the outer side surface of the flip-type side lower sleeve arm 6 and the upper end of the outer side surface of the sliding side upper 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 be translated and conveyed on the main frame 1. The function of the electric drive wheel 8 is to be inserted into the grooves on both sides of the cut surface of the corrugated pipe for guiding and driving.

[0031] In order to cooperate with the translational guidance, side sliding guide rods 9 are fixedly installed on both sides of the main frame 1 between the first electric-controlled conveyor belt 2 and the second electric-controlled conveyor belt 3, and the sliding translational guide seat 4 is slidably assembled with the side sliding guide rods 9 by being sleeved on the side sliding guide rods 9.

[0032] In order to cooperate with the lateral translation adjustment, side synchronous push rods 10 for controlling the sliding translation guide seat 4 are fixedly installed on both sides of the main frame 1.

[0033] The side synchronous push rod 10 controls the sliding translation guide seat 4 to perform translation adjustment along the side sliding guide rod 9 by telescoping.

[0034] In order to cooperate with the 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 electric-controlled cutting machine 5 includes an arc-shaped assembly seat 51 slidably assembled inside the guide groove at the upper end of the electric-controlled lifting guide rail 11 and an electric-controlled cutting blade 52 mounted on the upper end of the arc-shaped assembly seat 51 through an upper end bracket.

[0036] The electrically controlled cutting blade 52 is composed of a side drive motor installed in an arc-shaped cutting groove inside the arc-shaped assembly seat 51 and a cutting blade installed on a lateral drive shaft of the side drive motor.

[0037] In order to cooperate with lateral flipping adjustment, lateral mounting frames 53 for mounting the flip-type side lower sleeve arms 6 are fixedly mounted on both sides of the arc-shaped mounting seat 51, and lateral adjustment struts 54 for controlling the flipping of the flip-type side lower sleeve arms 6 are mounted on the lower ends of the outer sides of the lateral mounting frames 53.

[0038] The side adjustment support rod 54 is adjusted by telescopically controlling the flip-type side lower sleeve arm 6 to flip.

[0039] In order to cooperate with sliding and telescopic movement, a side storage frame 12 for storing the sliding side upper sleeve arm 7 is fixed on the outer side surface of the flip side lower sleeve arm 6, and a side upper adjustment motor 13 for controlling the sliding side upper sleeve arm 7 is installed on the outer side surface of the side storage frame 12.

[0040] An arc-shaped adjustment tooth groove is provided on the outer side of the sliding side upper sleeve arm 7, and the side upper adjustment motor 13 is connected to the sliding side upper sleeve arm 7 through the adjustment gear meshed with the arc-shaped adjustment tooth groove on the adjustment shaft, so as to lift the sliding side upper sleeve arm 7 to slide and adjust inside the side storage frame 12. When the side adjustment strut 54 controls the flip side lower sleeve arm 6 to flip to both sides of the corrugated pipe by stretching, the electric drive wheel 8 at the lower end of the outer side surface of the flip side lower sleeve arm 6 and the upper end of the outer side surface of the sliding side upper sleeve arm 7 are pressed against the grooves on both sides of the corrugated pipe, at this time, the side upper adjustment motor 13 drives the sliding side upper sleeve arm 7 to rotate along the guide grooves on both sides of the cut surface of the corrugated pipe by rotating, so as to rotate in a circle along the cut surface of the corrugated pipe, so as to cut the corrugated pipe one circle.

[0041] In order to separate and extract dust, lateral isolation covers 14 are fixedly mounted on both side surfaces of the arc-shaped assembly seat 51 , and a side dust collecting box 16 with a built-in centrifugal air pump 15 is fixedly mounted on the outer side surface of the lateral isolation cover 14 .

[0042] The centrifugal vacuum pump 15 is a prior art, which sucks dust into the side dust box 16 through the dust extraction holes on the side isolation cover 14, and then facilitates lateral dust collection while cutting. The centrifugal vacuum pump 15 runs synchronously with the electric-controlled cutting blade 52.

[0043] In order to cooperate with lifting, the electrically controlled lifting guide rail 11 includes a scissor-type lift 111 installed on the sliding translation guide seat 4 and a translation guide rail 112 installed on the upper end of the scissor-type lift 111.

[0044] The scissor lift 111 is a prior art, which controls the lateral extension and retraction of the electrically controlled support rods on the sliding translation guide seat 4, thereby adjusting the longitudinal height of the translation guide rail 112.

[0045] In order to improve the lateral stability of the translation guide rail 112 during lifting, the sliding translation guide seat 4 is provided with a guide limit rod 17 for improving the stability of the translation guide rail 112 .

[0046] Arc-shaped limiting grooves cooperating with the guide limiting rods 17 are provided on both sides of the translation guide rail 112. The guide limiting rods 17 are inserted into the arc-shaped limiting grooves to be slidably assembled with the translation guide rail 112, thereby improving the stability of the translation guide rail 112 in different directions.

[0047] Working principle: The corrugated pipe moves along the first electric-controlled conveyor belt 2 to the second electric-controlled conveyor belt 3. When cutting is required, the side synchronous push rod 10 controls the sliding translation guide seat 4 to move along the side sliding guide rod 9 through telescopic control. The sliding translation guide seat 4 moves at the same speed at the bottom of the corrugated pipe. At this time, the side adjustment support rod 54 controls the flipping adjustment of the flip side lower sleeve arm 6 through telescopic control. Then the side upper adjustment motor 13 drives the sliding side upper sleeve arm 7 to rotate along the guide grooves on both sides of the cutting surface of the corrugated pipe. At this time, the electric drive wheel 8 and the electric-controlled cutting machine 5 are started, so that they rotate in a circle along the cutting surface of the corrugated pipe, thereby cutting the corrugated pipe for one circle. After completion, the above operation is reversed, and then the side synchronous push rod 10 drives the sliding translation guide seat 4 to slide and reset.
