Description

Technical Field

[0001] The present application relates to the technical field of corrugated pipe cutting devices, and specifically discloses a cutting device for the production of PE steel belt spiral corrugated pipes. Background Art

[0002] A corrugated pipe refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and telescoping direction. Its main uses are as a measuring element in pressure measuring instruments and in fields such as mechanical equipment, automation control, electricity, and automobiles.

[0003] The PE steel belt spiral corrugated pipe is a plastic protective casing extruded from polyethylene material. Polyethylene belongs to hydrocarbon polymers, has non-polar molecules, is resistant to acid and alkali corrosion, has a unique structure, high strength, is resistant to compression and impact, is convenient to connect, has good joint sealing, and has no leakage.

[0004] The existing corrugated pipe cutting devices mainly include a bottom support table, a support structure installed on the bottom support table, and a cutting structure installed on the bottom support table. The cutting structure consists of a cutting tool and a driving motor. The PE steel belt spiral corrugated pipe is cut by reciprocally pushing the driving motor and the cutting tool. Usually, the support structure includes two arc-shaped clamping plates with openings facing inward. The outer wall of the corrugated pipe is supported and fixed by closing the arc-shaped clamping plates and the two ends of the arc-shaped clamping plates. However, the arc of the arc-shaped clamping plates is fixed and the size is unchanged, and it cannot clamp the corrugated pipes smaller than the distance between the two arc-shaped clamping plates, that is, it cannot fix corrugated pipes of different sizes.

[0005] Therefore, in view of this, the inventor provides a cutting device for the production of PE steel belt spiral corrugated pipes to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to solve the problem that the existing corrugated pipe cutting devices cannot fix corrugated pipes of different sizes.

[0007] To achieve the above purpose, the basic scheme of the present utility model provides a cutting device for the production of PE steel belt spiral corrugated pipes, which includes a bottom support table, a cutting structure arranged on the bottom support table, a conveying structure arranged on the bottom support table, and a clamping structure arranged between the conveying structure and the cutting structure and used for clamping the PE steel belt spiral corrugated pipe. The conveying structure includes belt conveyor mechanisms symmetrically arranged on both sides of the bottom support table respectively and used for clamping and conveying the PE steel belt spiral corrugated pipe, and a relative driving mechanism arranged on the bottom support table and used for controlling the relative sliding of the belt conveyor mechanisms. A material supporting table for carrying the PE steel belt spiral corrugated pipe is arranged on the bottom support table between the two belt conveyor mechanisms.

[0008] The principle and effect of this basic scheme are as follows:

[0009] 1. Compared with the prior art, in the present utility model, the conveying structure conveys the PE steel belt spiral corrugated pipe to the cutting structure. The clamping structure between the conveying structure and the cutting structure plays a role in fixedly clamping the PE steel belt spiral corrugated pipe, and the supporting table installed on the bottom supporting platform functions to carry the PE steel belt spiral corrugated pipe during the transportation process. After the PE steel belt spiral corrugated pipe extends a certain distance from the conveying structure, the cutting structure cuts the extended PE steel belt spiral corrugated pipe into corrugated pipe segments of a predetermined length to complete the cutting work.

[0010] 2. Compared with the prior art, the present utility model is also provided with a relative driving mechanism. The relative driving mechanism controls the belt conveyor mechanism that can slide on the bottom supporting platform. A clamping structure is installed on one side of the belt conveyor mechanism close to the cutting structure. The opening or closing of the relative driving mechanism drives the opening or closing of the belt conveyor mechanism to drive the clamping structure to clamp PE steel belt corrugated pipes of different sizes, solving the problem that the existing corrugated pipe cutting device cannot fix corrugated pipes of different sizes.

[0011] Furthermore, a guiding chute is provided at the top of the bottom supporting platform. The relative driving mechanism includes a lead screw rotatably connected in the guiding chute and symmetrically provided with external threads with opposite helix directions, sliders symmetrically arranged in the guiding chute and threadedly connected to the lead screw and relatively sliding, and a handwheel rotatably connected to the outside of the blanking table and capable of driving the lead screw to rotate synchronously. The belt conveyor mechanisms are respectively mounted on the sliders. The rotation of the handwheel drives the sliders to slide relatively through the lead screw, and the sliders drive the belt conveyor mechanisms to move relatively. The relative movement of the belt conveyor mechanisms can clamp and convey PE steel belt spiral corrugated pipes of different sizes.

[0012] Furthermore, the belt conveyor mechanism includes a mounting plate provided on the slider, a driving shaft and a driven shaft rotatably connected to the mounting plate, belt pulleys respectively coaxially provided on the driving shaft and the driven shaft, and a second driving motor provided on the mounting plate to drive the driving shaft to rotate. A belt is connected between the belt pulleys. The second driving motor drives the belt pulleys through the driving shaft and then drives the belt between the belt pulleys. The belt drives the PE steel belt spiral corrugated pipe placed on the supporting table to move synchronously.

[0013] Furthermore, vertical protrusions that can be inserted into the gaps between the outer walls of the PE steel belt spiral corrugated pipe are provided on the surface of the belt, and a pressing plate for tightening the belt and closely fitting the outer side of the PE steel belt spiral corrugated pipe is fixedly connected to the mounting plate on the inner side of the belt. The vertical protrusions on the surface of the belt and the pressing plate on the inner side of the belt effectively prevent the PE steel belt spiral corrugated pipe from slipping during the belt conveying process.

[0014] Furthermore, the clamping structure includes a clamping plate disposed at one end of the mounting plate facing the cutting structure. A cross plate is detachably connected between the clamping plates and is respectively located on the upper and lower sides of the PE steel belt spiral corrugated pipe. The distance between the two clamping plates is equal to the distance between the two belts. The inner end faces of the cross plates are in line contact with the PE steel belt spiral corrugated pipe. Elastic cushions are fixedly connected to the inner sides of the clamping plates and the cross plates. The detachable connection of the clamping plates and the cross plates facilitates the clamping and fixing of PE steel belt spiral corrugated pipes with different diameters.

[0015] Further, a number of column grooves are formed on the two clamping plates. A number of vertical plates are fixedly connected to both sides of the cross plate. Bolt holes that can communicate with the column grooves respectively are formed on the vertical plates, and bolts passing through the column grooves and pressing against the clamping plates are placed in the bolt holes. The cross plate can be installed at different heights on the clamping plates by moving the vertical plates on the column grooves, which is convenient for adjusting the distance between the cross plates.

[0016] Further, the cutting structure includes a hydraulic cylinder disposed on the bottom support table, a support plate disposed at the output end of the hydraulic cylinder. A cutting tool is provided on one side of the support plate, and a driving motor for driving the cutting tool to rotate is provided on the other side. The driving motor drives the cutting tool to rotate and the hydraulic cylinder drives the cutting tool to make a reciprocating motion to jointly complete the cutting work of the PE steel belt spiral corrugated pipe.

[0023] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features and effects of the present utility model as follows.

[0024] The reference numerals in the accompanying drawings of the specification include: bottom support table 1, first driving motor 2, support plate 3, blade 4, clamping plate 5, mounting plate 6, bellows 7, second driving motor 8, column groove 9, handwheel 10, lead screw 11, belt 12, belt pulley 13, cross plate 14, vertical plate 15, material supporting table 16, hydraulic cylinder 17, guiding chute 18, slide rail 19, abutting plate 20, slider 21.

[0025] A cutting device for producing PE steel belt spiral bellows, as shown in the embodiments Figure 1 as follows:

[0026] It includes a bottom support table 1, a cutting structure installed on the bottom support table 1 for cutting the PE steel belt spiral bellows 7, a conveying structure for conveying the PE steel belt spiral bellows 7 to the cutting structure, and a clamping structure installed between the conveying structure and the cutting structure.

[0027] On the bottom support table 1, there is also a discharge chute for the cut PE steel belt spiral bellows 7 to fall, and at the same time, a cutting groove is also opened on the bottom support table 1 on the left side of the discharge chute.

[0028] The cutting structure includes a hydraulic cylinder 17 installed on the bottom support table 1, a support plate 3 fixed to the top of the output end of the hydraulic cylinder 17 and having a shaft hole, a rotating shaft installed on the support plate 3 through the shaft hole and capable of rotating, a blade 4 coaxially and fixedly installed on the rotating shaft, and a driving mechanism installed on the right side of the support plate 3, and the blade 4 travels in the cutting groove. Specifically, the driving mechanism includes a box body installed on the right side of the support plate 3 and a first driving motor 2 installed in the box body, and the output shaft of the first driving motor 2 is coaxially connected to the rotating shaft.

[0029] The conveying structure includes belt conveying mechanisms respectively installed on both sides of the bottom support table 1 and capable of sliding relatively, and a relative driving mechanism installed on the bottom support table 1 for controlling the relative sliding of the belt conveying mechanisms. A material supporting table 16 for carrying the PE steel belt spiral bellows 7 is installed on the bottom support table 1 between the two belt conveying mechanisms.

[0030] As Figure 2 shown, the bottom support table 1 is provided with a guiding chute 18, the guiding chute 18 is perpendicular to the traveling direction of the PE steel belt spiral bellows 7, and the relative driving mechanism for controlling the relative sliding of the two belt conveying mechanisms is installed in the guiding chute 18.

[0031] The relative driving mechanism includes a lead screw 11 installed in the guiding chute 18. Opposite external threads with opposite helix directions are symmetrically formed at both ends of the lead screw 11. Sliders 21 are respectively and slidably connected to both ends of the guiding chute 18. Threaded holes that are threadedly connected to the lead screw 11 at the same end are respectively formed in the sliders 21 within the guiding chute 18. The belt 12 transmission mechanisms are respectively mounted on the sliders 21. A handwheel 10 that is rotatably connected to the outside of the material supporting table 16 and can drive the lead screw 11 to rotate is provided. Specifically, internal threaded holes through which the lead screw 11 passes and is threadedly connected to the external thread of the lead screw 11 are formed in the sliders 21. The internal threads inside the internal threaded holes of the two end sliders 21 have opposite helix directions and are respectively meshed with the external threads at the same end of the lead screw 11. When the two end sliders 21 are driven by the lead screw 11, they are limited by the guiding chute 18 and thus can only perform relative sliding along the direction of the guiding chute 18.

[0032] In this embodiment, slide rails 19 are symmetrically installed on both sides inside the guiding chute 18 along the extending direction of the lead screw 11. The sliders 21 are also provided with limiting chutes into which the slide rails 19 are inserted and within which the slide rails 19 can slide. During the sliding process of the sliders 21 within the guiding chute 18, the sliders 21 also slide along the slide rails 19. Mounting plates 6 are also respectively mounted on the sliders 21.

[0033] The clamping structure includes clamping plates 5 that are all mounted on the ends of the mounting plates 6 facing the cutting structure. A cross plate 14 located on the upper and lower sides of the PE steel belt spiral corrugated pipe 7 is installed between the two side clamping plates 5. The inner end faces of the two cross plates 14 are respectively in line contact with the upper top and lower bottom of the PE steel belt spiral corrugated pipe 7. A gap for the PE steel belt spiral corrugated pipe 7 to pass through is provided between the two side clamping plates 5. Elastic cushions are fixedly installed on the inner sides of the clamping plates 5 and the cross plate 14. Specifically, two column grooves 9 are respectively formed in the clamping plates 5. A vertical plate 15 is installed on both sides of the cross plate 14. A bolt hole opposite to the column groove 9 in the clamping plate 5 is formed in the vertical plate 15. After the bolt hole is aligned with the column groove 9, a bolt is installed between the bolt hole and the column groove 9 to fix the relative positions of the vertical plate 15 and the clamping plate 5.

[0034] The belt transmission mechanism includes a mounting plate 6 mounted on the slider 21, a driving shaft and a driven shaft rotatably mounted on the mounting plate 6, belt pulleys 13 coaxially mounted on the driving shaft and the driven shaft, and a second driving motor 8 whose output shaft is coaxially connected to the driving shaft. A belt 12 is connected between the belt pulleys 13. The distance between the two side belts 12 is equal to the distance between the two side clamping plates 5. A pressing plate 20 is mounted on the inner side of the belt 12 that fits the PE steel belt spiral corrugated pipe 7. The bottom of the pressing plate 20 is fixedly mounted on the mounting plate 6. The pressing plate 20 tightens the belt 12 to make it closely fit the outer surface of the PE steel belt spiral corrugated pipe 7. The second driving motor 8 drives the belt 12 to move through the belt pulleys 13. Vertically protruding portions that can be caught in the gaps between the outer walls of the PE steel belt spiral corrugated pipe 7 are fixedly installed on the surface of the belt 12.

[0035] When the utility model is in use, first place the PE steel belt spiral corrugated pipe 7 on the material supporting table 16. At this time, the bottom cross plate 14 is flush with the top end face of the material supporting table 16. Rotate the hand wheel 10. The hand wheel 10 drives the slider 21 in the relative driving mechanism to slide relatively on the slide rails 19 on both sides of the bottom supporting table 1, so that the belt conveying mechanism approaches the PE steel belt spiral corrugated pipe 7. The belts 12 in the two belt conveying mechanisms respectively clamp and convey both sides of the PE steel belt spiral corrugated pipe 7.

[0036] Start the second driving motor 8. The second driving motor 8 drives the belt 12 to move through the pulley 13 connected coaxially, achieving the effect of conveying the PE steel belt spiral corrugated pipe 7 to the cutting structure. The PE steel belt spiral corrugated pipe 7 is conveyed to the clamping plate 5 through the movement of the belt 12. The clamping plate 5 and the cross plate 14 fix the height of the PE steel belt spiral corrugated pipe 7 and ensure its horizontal forward conveyance.

[0037] After the PE steel belt spiral corrugated pipe 7 extends out of the clamping plate 5 by a predetermined length, first start the first driving motor 2 to drive the blade 4 to rotate, and then start the hydraulic cylinder 17 to push the support plate 3 to extend, so that the blade 4 cuts the PE steel belt spiral corrugated pipe 7.

[0038] When it is necessary to cut another size of the PE steel belt spiral corrugated pipe 7, for example, when cutting the PE steel belt spiral corrugated pipe 7 smaller than the predetermined size, rotate the hand wheel 10. The rotation of the hand wheel 10 drives the lead screw 11 to rotate synchronously, and drives the mounting plate 6 at the same end to slide inwards synchronously through the sliders 21 respectively installed at both ends of the lead screw 11, so that the gap between the two belts 12 is equal to the diameter of the PE steel belt spiral corrugated pipe 7. At the same time, replace the cross plate 14, and select a cross plate 14 with a width equal to the diameter of the PE steel belt spiral corrugated pipe 7 and install it in the clamping plate 5, then the conveyance and clamping of the PE steel belt spiral corrugated pipe 7 can be realized.

[0039] When it is necessary to cut the PE steel belt spiral corrugated pipe 7 larger than the predetermined size, rotate the hand in the reverse direction. The rotation of the hand drives the lead screw 11 to rotate synchronously, and drives the mounting plate 6 at the same end to slide outwards synchronously through the sliders 21 respectively installed at both ends of the lead screw 11, so that the gap between the two belts 12 is equal to the diameter of the PE steel belt spiral corrugated pipe 7. At the same time, replace the cross plate 14, and select a cross plate 14 with a width equal to the diameter of the PE steel belt spiral corrugated pipe 7 and install it in the clamping plate 5, then the conveyance and clamping of the PE steel belt spiral corrugated pipe 7 can be realized.

[0040] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
