Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment, specifically a simple plastic pipe length cutting device. Background Technology

[0002] Plastic pipes are generally made from synthetic resin, specifically polyester, with the addition of stabilizers, lubricants, and plasticizers, through extrusion processing in a pipe-making machine. They are mainly used for piping in building water supply systems, drainage, ventilation, and sewage systems; underground drainage systems; rainwater pipes; and conduits for electrical wiring. Before use, plastic pipes typically need to be cut according to the intended application for easy assembly.

[0003] Existing methods for cutting plastic pipes typically involve workers measuring the pipes on-site with a tape measure and then cutting them with an angle grinder. When cutting large quantities of pipes, manual cutting is inefficient, prone to errors, and affects usability. Furthermore, using an angle grinder poses safety risks. Therefore, those skilled in the art have provided a simple, fixed-length plastic pipe cutting device to address the problems described in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a simple plastic pipe length cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A simple plastic pipe length cutting device includes a worktable, a cutting length limiting plate, and a pipe clamping plate. Four support legs are welded to the four corners of the bottom of the worktable. A clearance groove is provided at the center of the worktable's fixed section. A cutting machine is fixedly connected below the clearance groove, and the cutting machine's blade extends partially out of the clearance groove. Two first sliding grooves are arranged perpendicular to the clearance groove on one side of the clearance groove. An L-shaped cutting length limiting plate is provided above the first sliding grooves. Two bolts penetrating the first sliding grooves are symmetrically arranged on the horizontal plate of the cutting length limiting plate and are fixedly connected with nuts. Two sets of four second sliding grooves are symmetrically arranged parallel to the clearance groove on the other side of the clearance groove. An L-shaped pipe clamping plate is provided at the top of each set of second sliding grooves. Two bolts penetrating the second sliding grooves are symmetrically arranged on the horizontal plate of the pipe clamping plate and are fixedly connected with nuts.

[0007] As a further embodiment of this utility model: guide cylinders are symmetrically welded to both ends of the clearance groove on the surface of the workbench; a support beam is bolted to the bottom of the cutting machine; adjusting rods are welded to both ends of the support beam; adjusting nuts are threaded to the top of the adjusting rods; adjusting nuts are also threaded to the bottom of the workbench; and the adjusting rods are slidably connected to the guide cylinders.

[0008] As a further embodiment of this utility model: an adjustment base plate is welded to the top of the workbench at one end where the cutting length limiting plate is located; a screw is rotatably connected to the middle of the adjustment base plate; a handwheel is welded to the tail of the screw; an adjustment sleeve is welded to the center of the back of the cutting length limiting plate; and the adjustment sleeve is connected to the screw by threads.

[0009] As a further embodiment of this utility model: guard plates are fixedly connected to the two end faces and one side of the workbench by bolts, and a flap is connected to the other side of the workbench by a hinge.

[0010] As a further embodiment of this utility model: an inverted L-shaped downward pressure support plate is welded to the back of the cutting length limiting plate, a downward pressure connector is slidably connected to the top of the horizontal plate of the downward pressure support plate, a pressure roller is threadedly connected to the bottom of the downward pressure connector, and a downward pressure spring is provided around the downward pressure connector between the pressure roller and the downward pressure support plate.

[0012] As a further improvement of this utility model, a pull ring is welded to the top of the pressing connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the locking of the cutting length limiting plate and the pipe clamping plate is unlocked by loosening the bolts and nuts. The distance between the cutting length limiting plate and the cutting machine blade is changed by rotating the handwheel to drive the screw to rotate, thereby changing the length of the plastic pipe to be cut. The distance between the two pipe clamping plates is changed, thereby changing the diameter of the processed pipe. It is easy to use. The top of the plastic pipe to be processed is placed against the side of the cutting length limiting plate. After pressing the pipe down to fit against the worktable, the plastic pipe is rotated. The cutting machine blade penetrates the inner wall of the plastic pipe to perform a circumferential cut on the plastic pipe. It is easy to use and has high processing accuracy.

[0015] 2. In this utility model, when peeling PPR pipe (random copolymer polypropylene pipe), the adjusting nut is rotated to make the adjusting rod slide and the guide cylinder slide, changing the height of the support beam, thereby changing the size of the cutting machine blade extending out of the worktable, so that the blade does not penetrate the inside of the plastic pipe. After the normal cutting of plastic pipe is completed, the pipe is pulled horizontally and slid across the cutting machine blade, which can quickly remove the peeled outer layer. The operation is simple and convenient.

[0016] 3. In this utility model, when cutting large-sized plastic pipe fittings, the locking rod is pulled out, and the lower connecting piece moves down under the action of the lower spring, pressing the pressure roller against the top of the pipe fitting. As the pipe fitting rotates, the pressure roller rotates accordingly, effectively preventing the pipe fitting from jumping. It is convenient to use and has better safety. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4In this embodiment of the present invention, a simple plastic pipe length-limiting cutting device includes a workbench 1, a cutting length limiting plate 6, and a pipe clamping plate 21. Four support legs 2 are welded to the four corners of the bottom of the workbench 1. A clearance groove 16 is provided at the center of the fixed part of the workbench 1. A cutting machine 17 is fixedly connected below the clearance groove 16. The blade of the cutting machine 17 extends a portion beyond the clearance groove 16. Two first sliding grooves 10 are provided on one side of the clearance groove 16 perpendicular to the direction of the clearance groove 16. An L-shaped cutting length limiting plate 6 is provided above the first sliding grooves 10. Symmetrically arranged on the horizontal plate of the cutting length limiting plate 6 are... Two bolts passing through the first slide groove 10 are fixedly connected with nuts. The distance between the cutting length limiting plate 6 and the blade of the cutting machine 17 can be flexibly adjusted, making it easy to adjust the length of the cut plastic pipe. On the other side of the clearance groove 16, two sets of four second slide grooves 20 are symmetrically arranged parallel to the direction of the clearance groove 16. Each set of second slide grooves 20 has an L-shaped pipe clamping plate 21 at the top. Two bolts passing through the second slide groove 20 are symmetrically arranged on the horizontal plate of the pipe clamping plate 21 and fixedly connected with nuts, making it easy to adjust the diameter of the clamped pipe. It is convenient to use, has high cutting accuracy, and is safer to cut.

[0024] The workbench 1 has guide cylinders 18 symmetrically welded to both ends of the clearance groove 16. The bottom of the cutting machine 17 is connected to a support beam 22 by bolts. The two ends of the support beam 22 are welded to adjusting rods 23. The top of the adjusting rods 23 is connected to adjusting nuts 19 by threads. The adjusting rods 23 are also connected to adjusting nuts 19 by threads at the bottom of the workbench 1. The adjusting rods 23 are slidably connected to the guide cylinders 18, which facilitates the adjustment of the length of the cutting machine 17 blade extending out of the workbench 1. This allows for the stripping of PPR pipes (random copolymer polypropylene pipes) and is easy to use.

[0025] Among them, an adjustment base plate 5 is welded to the top of the workbench 1 at one end where the cutting length limiting plate 6 is located. A screw 8 is rotatably connected to the middle of the adjustment base plate 5. A handwheel 9 is welded to the tail of the screw 8. An adjustment sleeve 7 is welded to the center of the back of the cutting length limiting plate 6. The adjustment sleeve 7 is connected to the screw 8 by a thread. The handwheel 9 drives the screw 8 to make the cutting length limiting plate 6 slide along the first slide groove 10. It is convenient to use and has high adjustment accuracy.

[0026] Among them, the two end faces and one side of the workbench 1 are fixed with guard plates 3 by bolts to prevent the blade of the cutting machine 17 from breaking and injuring the workers. The other side of the workbench 1 is connected with a flap 4 by a hinge to facilitate the maintenance of the cutting machine 17 at the bottom of the workbench 1.

[0027] Among them, the back of the cutting length limiting plate 6 is welded with an inverted L-shaped downward pressure support plate 11. The top of the horizontal plate of the downward pressure support plate 11 is slidably connected to a downward pressure connector 12. The bottom of the downward pressure connector 12 is connected to a pressure roller 15 by a thread. A downward pressure spring 14 is provided around the downward pressure connector 12 between the pressure roller 15 and the downward pressure support plate 11. When the diameter of the pipe is large, the pressure roller 15 is used to assist in positioning the pipe to prevent the pipe from jumping and causing danger.

[0028] The pressing connector 12 has a locking hole 24 through the middle, and an L-shaped locking rod 13 is slidably connected in the locking hole 24. When the pressing connector 12 is not used to assist in positioning the pipe, it is convenient to lock the downward movement of the pressing connector 12.

[0029] The top of the pressing connector 12 is welded with a pull ring 25, which facilitates lifting the pressing connector 12 and makes it easy to place the pipe fitting between the two pipe fitting clamping plates 21, making it convenient to use.

[0030] The working principle of this utility model is as follows: Based on the required pipe dimensions, first loosen the bolts and nuts to unlock and adjust the locking of the cutting length limiting plate 6 and the pipe clamping plate 21. Then, rotate the handwheel 9 to drive the screw 8 to rotate, changing the distance between the cutting length limiting plate 6 and the cutting machine blade 17, thereby changing the length of the plastic pipe to be cut. Manually change the distance between the two pipe clamping plates 21, thereby changing the diameter of the processed pipe. Finally, lock all the bolts and nuts to lock the cutting length limiting plate 6 and the pipe clamping plate 21. This method offers high processing precision and ease of use. Place the top of the plastic pipe to be processed against the side of the cutting length limiting plate 6, and press the pipe down against the worktable. 1. After the plastic pipe is fitted, rotate it. The blade of the cutting machine 17 penetrates the inner wall of the plastic pipe to make a circumferential cut, thus cutting the pipe. When the pipe is large and there is jumping when rotating, pull out the locking rod 13. The lower connecting piece 12 moves down under the action of the lower spring 14, and the pressure roller 15 is pressed against the top of the pipe. As the pipe rotates, the pressure roller 15 rotates accordingly, effectively preventing the pipe from jumping and making it safer to use. When peeling PPR pipe, adjust the position of the adjusting nut 19 on the two adjusting rods 23 to change the length of the cutting machine 17 blade extending out of the worktable 1, so that the blade does not penetrate the inner wall of the pipe, thus achieving the peeling operation. It has a wide range of applications and is easy to operate.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
