Description

Technical Field [0001] The present invention relates to a multifunctional pipe slice device,

The present invention relates to a pipe cutting apparatus having a predetermined length, and more particularly, to a cutting apparatus for cutting a circumference of a pipe using a separate rotary cutting edge,

Basically, the entire structure of the cutting device is simplified to make it easy to manufacture and use, and at the same time, various functions can be exhibited even at a low price so as to increase the popularity of the product,

The pressing force applied to the contact point between the cutting blade and the pipe during the cutting process is dispersed throughout the entire pipe without being concentrated at a specific point, thereby preventing a shape change phenomenon such as a specific cutting point of the pipe being distorted during the cutting process. It is possible to stably position pipes of various diameters so that pipes of various diameters can be cut. In addition, it is possible to prevent unnecessary shaking of the pipe during the cutting process, The structure of the seat body on which the pipe is seated is improved and the longitudinal length can be adjusted according to the length of the pipe so that the pipes of various lengths can be stably fixed and fixed and the position of the cutting point can be precisely set It is the contents which it made.

In general, metal or plastic pipes are widely used for building materials and machine structural materials.

Most of these pipes are formed by using extrusion method and then cut by a desired length. Basically, the pipe is firstly cut from the first manufacturer by a certain length and then delivered to the delivery place. Then, at the delivery place, Depending on the type of industry, it will be cut again in various sizes.

However, in the case of a company that cuts pipes at various times in such various lengths, it is economically difficult to use a large-sized cutting apparatus used by a manufacturer because most of them are small and medium-sized companies.

Therefore, the company cuts the pipe by using a small cutting device. In the conventional small-sized pipe cutting device, the up-and-down turning lever is located on one side of the seat plate of the simple plate shape. It consists of a structure in which the blade is installed.

In this state, while the pipe is seated on the seat plate, the worker presses the pipe with one hand to fix the position, and then the rotary lever is lowered with the other hand, so that the rotary cutting edge is positioned on the upper side of the peripheral surface of the pipe So that the pipe is cut as the rotary lever and the rotary cutting blade are lowered further downward.

However, the conventional pipe cutting apparatus has the following problems.

First, since the rotary cutting blade is further lowered through the rotary lever in a state where the rotary cutting edge is in contact with a specific point on the circumferential surface of the pipe while being lowered, the remaining portion of the pipe peripheral surface is also sequentially cut. The pressing load must be concentrated at the point where the rotary cutting blade first contacts the peripheral surface.

Therefore, the phenomenon that the cutting point of the pipe is distorted downward is easily generated in the process of cutting the rotary cutting blade, so that the additional work of recovering the distorted point after the cutting work is performed through the separate processing Must be carried out.

Of course, in recent years, a pipe has been seated on a separate roller, and a structure has been proposed in which the pressing force applied to the pipe is dispersed by making the cutting while rotating the pipe by the rotational force of the rotary cutting edge at the time of contact between the rotary cutting edge and the pipe There is.

However, in the related art, the rotation of the pipe is rotated only by the contact force of the rotary cutting edge, so that the rotation direction is not only in the same direction as the rotary cutting edge, but also the cutting is performed in a state where the rotary cutting edge is fixed in position There is a fatal problem that the cutting time is long.

In addition, since the related art requires a position setting process to accurately position the rotary cutting edge according to the diameter of the pipe before the cutting operation, it takes a longer time for the cutting operation as a whole, The position of the rotary cutting blade must be adjusted every time the pipe diameter is changed. Therefore, the troublesome operation is required and the entire working time is further delayed.

Secondly, in the prior art, when the pipe is fixed on the pipe, the pipe is simply placed on the pipe, and the pipe is cut by the lowering of the rotary lever and the rotary cutting blade with the other hand, In this case, in this case, there is a high possibility that the pipe moves finely due to the force momentarily applied to the pipe by the rotation of the rotary cutting blade in the cutting process. Therefore, precise cutting processing is practically impossible and inevitably, There is an inconvenience that it is necessary to perform post-processing such as grinding and cutting the cutting point separately.

Recently, a technique has been proposed in which a rotary cutting blade is first pressed against a circumferential surface of a pipe before the cutting, and then the rotary cutting blade is rotated to perform cutting.

However, according to the related art, since the pressurization for fixing the position of the pipe is performed by the rotary cutting edge, the position of the rotary cutting edge is adjusted up and down before the cutting operation at all times, It is very cumbersome because the work must be done and it becomes a cause of deterioration of the overall working efficiency.

In addition, when pipes of various diameters are cut, the position of the rotary cutting edge must be changed every time, so that troublesome work is doubled.

Thirdly, since the position fixing of the pipe is performed only by the pressing force of the user's hand or the rotating cutting edge, it is difficult to uniformly stably fix the pipe of each diameter when cutting pipes of various diameters.

Fourth, in the prior art, since the seating plate on which the pipe is seated is in the form of a simple plate, and its longitudinal length can not be adjusted, when the pipe is seated at the time of cutting the relatively long pipe, The pressing force can not be applied over the whole length of the pipe, and therefore, it is difficult to stably fix the pipe in the case of a pipe having a long length.

Fifth, in the related art, a process of placing a point to be cut in a pipe under a rotary cutting edge is measured by a worker measuring a cutting point of the pipe by using a tape measure or the like, It is moved directly to be positioned at the upper and lower collinear points, and then the position is fixed and cut.

Therefore, it is difficult for the cutting point of the pipe to be positioned exactly on the same line-up position with the rotating cutting edge, which makes it difficult to perform precise machining operations.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art,

First, the entire structure of the cutting device is simplified to make it easy to manufacture and use, and at the same time, various functions can be exhibited at a low price, thereby enhancing the popularity of the product.

Second, the pressing force applied to the point of contact between the cutting blade and the pipe during the cutting process of the pipe is dispersed throughout the pipe without being concentrated at a specific point, thereby causing a shape change such as a certain cutting point of the pipe being distorted in the cutting process However,

The cutting time is minimized and the process of adjusting the upper and lower positions of the cutting blade before cutting must be performed separately beforehand by making the cutting while the pipes are individually rotated through the separate driving source instead of the rotation by the rotational force of the rotary cutting blade Avoid cumbersome work and total work delay.

Third, the structure of the pipe is improved so that the pipes of various diameters can be stably installed at all times.

Fourthly, since the pressing force for fixing the position of the pipe is pressed by the separate pressing structure without depending on the pressing force of the operator's hand or the rotary cutting edge, the position fixing of the pipe can basically be performed stably and reliably, Since it does not depend on the pressing force of the blade, it is not necessary to carry out the process of adjusting the vertical position of the rotary cutting blade before cutting in order to pressurize the whole wave before cutting, thereby shortening the working time, It is possible to prevent the inconvenience caused by the advance position adjustment of the rotary cutting edge.

Fifth, since the length of the seat body on which the pipe is seated can be adjusted according to the longitudinal length of the pipe, even when the long pipe is seated, the pressing force is transmitted along with the stable seating of the pipe over the entire length of the pipe Thereby preventing unwanted shaking of the pipe during the cutting process.

Sixth, it is not necessary for the worker to move the pipe one by one, so that the cutting point of the pipe is accurately positioned on the lower side of the rotating cutting edge, so that the pipe cutting point is always positioned at the lower co- Minimize the hassle of work and ensure precise cutting of precise points at all times.

According to the present invention as described above,

The overall structure of the cutting device is simplified compared to the conventional large-sized cutting device, so that it can be manufactured and used conveniently by a small and medium sized company, and at the same time, various functions can be exhibited at a low price.

Since the pipe is rotated by the second driving motor and the first pressurizing rotating roller through the separate driving force to make contact with the rotary cutting blade, the pressing force applied to the contact point between the rotary cutting blade and the pipe during the cutting process is It is dispersed throughout the pipe without concentrating on the point, so that the shape change such as collapsing the specific cutting point of the pipe during the cutting process is prevented.

In particular, since the cutting is performed while the pipes are individually rotated through the separate driving source instead of the rotation by the rotational force of the rotary cutting edge, the cutting time is minimized and the process of adjusting the vertical position of the rotary cutting blade before cutting must be performed separately in advance The hassle is resolved.

The first to fourth press plates and the first upper press frame, the second upper press frame, the first constant pressure piece and the second upper press piece are separated from each other by the first to fourth press plates, Since the position is fixed in a pressed state through the pressing force of the pipe, the stable position fixation of the pipe can be maintained during the cutting process.

Since the pressing force for fixing the position of the pipe is pressed by the separate pressing structure without depending on the pressing force of the operator's hand or the rotating cutting edge, the position fixing of the pipe can basically be performed stably and reliably, Since the process of adjusting the position of the rotary cutting blade before cutting is not required to be performed beforehand in order to pressurize the entire cutting force due to the pressing force of the blade, the working time is shortened, It is possible to prevent the inconvenience caused by the advance position adjustment of the cutting edge.

Further, since the front and rear spaces are adjusted by the driving force of the length adjusting cylinder in a state where the first and second seating bodies are divided, even if the long pipe is seated, the pipe stays stable over the entire length of the pipe at all times The pressing force is transmitted as well as the supporting force can be exerted, so that unwanted shaking of the pipe in the cutting process can be prevented.

The pipe is pushed forward by the position adjusting cylinder in a state in which the pipe is positioned so as to be positioned at a predetermined position by the position adjusting piece and the point to be cut is accurately aligned with the rotating cutting edge So that a precise cutting operation can be performed.
