Abstract
Description
[0001] PIPE CUTTING ADJUSTMENT DEVICE
[0002] Technical Field
[0003] The invention relates to pipe cutting adjustment device.
[0004] The invention is especially relates to pipe cutting adjustment device, which allows the cutting group to be adjusted three axes, which was introduced to eliminate the problem of cutting to length encountered in the production of downspout pipes that drain water from the roofs of buildings by the roll forming method.
[0005] Background of the Invention
[0006] Rain pipes, known as downspout pipes, are a type of pipe used to carry rainwater from the rain gutter.
[0007] The purpose of the downspout is to ensure that water from the gutter reaches the ground without dripping or splashing onto the building structure. Downspouts are generally vertical and often extend to ground level, but may be oriented at an angle to avoid architectural features and discharge onto an intermediate roof.
[0008] The production of the mentioned rain pipes is carried out in roller forming machines called roll form. In the mentioned roll forming method; The sheet metal is bent and shaped with rolled rollers in order to bring it into the desired form. Rain pipes, also known as downspout pipes, are generally produced continuously by the roll forming method by feeding rolled sheet metal, and at the end of the process, they must be cut to the desired length.
[0009] In current applications, since the pipe is closed at the point where the mandrel is connected to the internal cutting tool coming from the pipe, the mandrel can be supported from the last point where the pipe is open, that is, at least 2 meters away from the point where the cutting is made. This causes the tip of the arbor to deviate from the cutting direction to the right, left or up or down at the point of cutting, preventing it from being in the desired position and angle.
[0010] In addition, since it is very difficult to precisely adjust the position of the base to which the external cutting blades are attached, especially angularly, due to the size and weight of the base, it is difficult to adjust the external blades in the correct position.
[0011] As a result of all these, in some cases the cutting quality is poor, and in some cases no cutting can be made, since the cutting gap that must be between the inner pocket blade and the outer blade for a smooth cut is different at each point. In addition, since different material uses require cutting gap adjustment, this adjustment is either very difficult or impossible in existing systems.
[0012] In some applications, cutting is done using only external tools, without using internal mandrels and pocket blades, which causes inward deformation of the pipe during cutting and burr cutting.
[0013] Regarding the subject in the patent application numbered KR102581807 in the literature, "The pipe manufacturing device according to the present invention is used to keep the height of the left and right ends of the strip steel plate constant in the process of welding the joint weld to the left and right ends of the plastically treated steel sheet strip and to keep the left and right ends of the plastically processed steel sheet strip is to minimize the height of the right ends. There is a gap between the left and right ends in the transfer direction. It is characterized by a pair of pressing tools placed between the first guide roll unit and the second guide roll unit along the welding unit to press the left and right ends of the steel sheet strip in the downward direction respectively. In particular, when the piping device of the present invention requires fine adjustment, which is difficult to adjust by merely manipulating the control program, the first guide roller unit on the left and right is operated by manipulating the adjustment knob of the inclined support roller. Height adjustment means and the height of each inclined support roller of the left and right second guide roller units can be precisely adjusted individually and independently.” statements are included. In said application, roll forming machine for stainless pipe is disclosed.
[0014] Again, in the Chinese utility model application numbered CN208220020 in the literature, it is stated that “The utility model discloses a rainwater fill buried sleeve, , which comprises a steel pip, the bottom of steel pipe is formed with three arc stabilizer blade through cutting an organic whole, and is three angular distribution such as arc stabilizer blade are in the bottom of steel pipe, and the bottom of the three arc stabilizer blade outside all welds the reinforcing bar, angle spiro unions suchas the upper portion of steel pipe have three fastening bolt, and are three fastening bolt sets up with three arc stabilizer blade is crisscross. The utility model discloses, can guarantee that the rainwater is fought steadily reaches roughness and the straightness's that hangs down requirement, reduces the elevation error, strengthens the stability that the rainwater was fought, the infiltrationis avoided to an organic whole nature of reinforcing and concrete, lays solid foundation for the later stage construction, has reduced the later stage and has done over again the process that causes and alternately, can make rainwater fill, downspout installation procedure fulfil ahead of schedule, cuts down the number of intermediate links and input artifical, the material, reduces engineering cost, improves the engineering quality, is worth popularizing.” statements are included.
[0015] In the mentioned application, the rainwater fill embedded sleeve device in the rain pipes is disclosed.
[0016] For the reasons mentioned above, a new pipe cutting adjustment device was needed.
[0017] Purpose of the Invention
[0018] Based on this state of the art, the aim of the invention is to introduce a new pipe cutting adjustment device that eliminates the existing disadvantages.
[0019] Another aim of the invention is to create a structure that allows the inner cutting blade to be parallel to the outer cutting tools on the mandrel. Another aim of the invention is to provide a structure that allows axial and angular adjustment to obtain the desired cutting gap.
[0020] Another aim of the invention is to provide a structure that provides a suitable cutting gap between the inner pocket blade and the outer blade, equal at every point and varying according to the sheet thickness.
[0021] Another aim of the invention is to provide a structure that allows pipes to be cut smoothly.

[0038] Figure - 1 shows a section and detail views showing pipe (1 ) length cutting in current technique.
[0039] Figure - 2 shows sectional and detail views showing the pipe (1 ) production with the pipe (1) cutting adjustment device that is the subject of the invention.
[0040] Figure - 3 shows detailed view of the pipe (1 ) cutting adjustment device that is the subject of the invention.
[0041] The pipe (1) cutting adjustment device, which is the subject of the invention, coninsts main parts of inner blade (2) positioned inside the pipe (1) to cut the said pipe (1), arbor (3) positioned as a shaft coming from the pipe (1) to realize the connection of the said inner blade (2), arbor support (4) formed to connect the arbor (3) from the open point of the pipe (1) in the most suitable position and an outer blade (5) positioned as a pocket blade group that cuts the said pipe (1) from the outside and is moved by a hydraulic cylinder, bolt (6) used as a fastening element for fixing the said inner blade (2) and the arbor (3), a washer (7) which ensures that the bolts (6) press parallel to the surface in every position, hanger bolt (8), which allows the said inner blade (2) to be freely connected to the arbor (3) during adjustment, spring (9) that provides axial pressure on the inner blade (2) during adjustment, adjusting bolt (10) provides both axial and angular adjustment of the said inner blade (2), fulfills the function of pressing flat on the surface in every position thanks to the sphere at its end being able to move 9° and the surface pressing on the arbor (3) is flat, and provides axial and angular adjustment to obtain the desired cutting gap.
[0042] With the pipe (1) cutting adjustment device that is the subject of the invention, hanger bolt (8), spring (9) and flat-ended ball joint adjusting bolt (10) are added to the connection of the arbor (3) and the inner blade (2).
[0043] By using the said hanger bolt (8) and adjusting bolt (10), it is ensured that the inner blade (2) is parallel to the outer blade (5) on the arbor (3) and can be adjusted axially and angularly to obtain the desired cutting gap. 3 adjusting bolts (10) placed at 120° angles are moved back and forth individually in the required amounts to reset the unwanted a and b angles seen in Figure 1 and return them to the appropriate cutting gaps as a=b seen in Figure 2.
[0044] In order for the pipe (1) cutting to be smooth, there must be a suitable cutting gap between the inner blade (2) and the outer blade (5) that is equal at every point and varies according to the sheet thickness. For this purpose, an arbor support (4) is first connected to the last suitable open point of the pipe (1 ) on the line. Afterwards, an arbor (3) that will support the inner blade (2) is connected to this support through the completely closed part of the pipe (1).
[0045] The said inner blade (2) is swivelly connected to the arbor (3) from the center by a combination of hanger bolt (8) and spring (9). With 3 flat ball-tipped adjusting bolts (10) positioned at 120° angles, the inner blade (2) is moved both linearly in the axial direction and angularly in all directions, ensuring that the inner blade (2) is parallel to the outer blade (5) in the appropriate cutting space. Moving all 3 of the flat ball-tipped adjusting bolts (10) by the same amount creates an axial movement, and moving any of them individually creates an angular movement. After all these adjustments are completed, the inner blade (2) is fixed to the arbor (3) by tightening three bolts (6), under which a washer (7) formed as a cup washer / conical washer set is placed under it so that it presses parallel to the surface.
[0046] During adjustment, the bolts (6) should not be tight but should allow movement. In this embodiment, smooth cutting of the pipes (1 ) is ensured by moving the outer blade (5) in a radial direction towards the inner blade (2).
