Description

TECHNICAL FIELD [0001] The present invention relates to a pipe groove forming method for a hot water mat,

The present invention relates to a method for machining a pipe groove of a hot water mat and a pipe groove forming apparatus for the same, and more particularly, to a pipe groove forming method for a hot water mat which maximizes processing precision of a pipe groove for inserting a hot water pipe, And more particularly, to a pipe groove forming method for a hot water mat and a pipe groove forming apparatus therefor.

Generally, a hot water mat is a heating device that uses hot water as a heat source, and generally includes a pipe groove recessed into a certain shape in a cushion pad for mat (hereinafter referred to as a "ply surface"), a hot water pipe inserted in the pipe groove, And an outer sheath that is processed on the upper and lower surfaces.

Accordingly, the hot water mat is supplied to the hot water pipe through the heating boiler installed at both ends of the hot water pipe, thereby providing a heating effect. Unlike the conventional electric mats, unlike the conventional electric mats, It has the advantage of being remarkably energy-efficient and has attracted more attention than electric mats in recent years.

The present invention is a method of forming a pipe groove of a certain shape in the hot water mat.

More specifically, there is a pipe groove forming process in which a pipe groove is formed in a predetermined shape (usually in a zigzag form) and a certain depth on the upper surface of a double layer in the manufacturing process of a conventional hot water mat. However,

A pipe groove forming step of forming a pipe path by forming a pipe path with a sponge piece or the like on the upper surface of the lapped surface,

And a pipe groove machining step in which the upper surface of the overlapped surface is grooved by a user at a predetermined depth to form a pipe groove.

Here, the two processes described above are manually performed by a worker, which takes a long time and a long period of time. In addition, it is also difficult to precisely process the pipe grooves as well as an excessive defect rate, and the hot water pipes of the hot water pipes are protruded upward There was a problem that it was possible to flow heavily, and in particular, it was an obstacle to the construction of an automatic hot-water mat in-line process.

In recent years, a pipe groove forming process has been proposed in which a pipe groove having a predetermined shape and a predetermined depth is formed on the upper surface of a double-sided surface by using an NC or CNC machine tool to partially solve the problem of the above example.

Above NC or CNC machine tool process is advantageous in reducing the number of workers and quick and easy operation compared to the process described above. Also, it is possible to construct in-line automatic process of hot water mat to help mass production of hot water mat. .

However, the NC or CNC machine tool typically forms a pipe groove by grooving in such a manner that the upper face of the double face is cut off while rotating the end mill (the cutting edge) at a high speed, and it takes much time to form the pipe groove Further, in the case of a double-sided surface for a hot water mat, since it is made of a weak material such as a sponge or a nonwoven fabric for the purpose of providing a cushion force, there is a possibility that the periphery of the working portion is torn or the cutting defect there was.

In other words, in the machine tool system, the defect rate of the work is very high, and irregular machining of the pipe groove, that is, the entire shape of the pipe groove (zigzag pattern) is not uniform, the inner surface of the pipe groove becomes rough, (Such as hot water pipe protrusion and flow, etc.) due to the problem of machining that the inner diameter is not uniform and the like, and the cutting shape of the pipe groove is shown in Fig. 9 There is a concern that the hot water pipes located in the pipe grooves may protrude and flow to the upper inlet portion as the inlet portion and the anchoring portion are formed to have the same size as shown in the drawings.

In addition to the above-mentioned problems, there is a problem that a large amount of chips and dispersions are generated during grooving due to the rotation of the end mill, which requires environmental pollution in the work space and unnecessary work due to the removal thereof, There was a problem of significantly increasing the cost of the process equipment and the cost of the product due to the high cost.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

It is a general feature of the present invention to provide a method and apparatus for processing a pipe groove with a double face of a hot water mat, The entire manufacturing method of the hot water mat is omitted or briefly described, and the same names are unified into one code to be described and described.

First, a conventional method of manufacturing a hot water mat includes a material preparation step (a), a pipe groove processing step (b), a hot water pipe seating step (c), a finish material attaching step (d) And a finishing step (e).

To explain this in detail,

* Material preparation process (a);

The above process is a process in which the cushion body used for the hot water mat, that is, the overlapping surface 1 is supplied to the upper position of the work shelf 2 and is in a standby state, (Prepare) the folded surface 1 which has been cut to the size.

Here, the overlapping surface is used as a cushioning material such as a sponge so as to provide installation and cushioning force of the hot water pipe.

* Pipe grooving process (b);

The above process refers to a process of forming a pipe groove 11 having a zig-zag shape and a certain depth repeated on the upper surface of the double-sided surface 1 when the above-described material preparing process is completed.

The pipe grooves are machined by grooving the upper surface of the lapped surface to such an extent that a hot water pipe can be installed.

* Hot water pipe installation process (c);

The above process refers to a process of installing the hot water pipe 3 in the same shape into the pipe groove 11 formed in the overlapping surface 1 when the pipe groove forming process is completed.

It is preferable that the hot water pipes are installed in the same shape in the zigzag type pipe grooves, and both ends of the hot water pipes are protruded by a predetermined length in one side direction.

(D) Process of attaching finish material;

The above process refers to a process of attaching the finishing material 4 to the upper surface of the overlapped surface 1 when the above described hot water pipe seating process is completed and the fixing of the hot water pipe 3 provided in the pipe groove 11 Purpose.

That is, in order to prevent the hot water pipe installed in the pipe groove from being protruded, the above process is performed by adhering a finishing material such as non-woven fabric or silver foil to the upper surface of the folded surface after the above- So that the conduction efficiency of heat can be increased.

Final finishing process (e);

The above step is a final step of completing the hot water mat by covering the outer surface 5 on the upper and lower surfaces of the overlapping surface 1 when the above-described finish material attaching step is completed. Usually, , A non-woven fabric or the like is bonded or bonded together to complete a hot water mat.

The present invention has a great feature in a pipe groove processing method newly proposed in the pipe groove processing step (b) in the above process.

That is, according to the present invention, in the above-described method for manufacturing a hot water mat, the pipe groove machining step (b) for machining the pipe grooves 11 on the upper surface of the overlapping surface (1) (102), a second heat processing step (103), and a heating steel wire returning step (104).

More specifically,

A lifting and lowering device 12 which is positioned at a predetermined distance from the upper side of the work shelf 2 and a lifting and lowering device 13 which is installed on the lifting and lowering steel plate 12, (Refer to Fig. 4), in which the folded surface 1 is positioned in the machining apparatus 101a composed of the heating steel wire 14 arranged in a staggered manner with a predetermined interval therebetween,

The step of preparing the double-sided surface refers to a step of positioning the double-sided surface with the working shelf positioned on the lower collinear line at a certain distance from the elevating and lowering plates of the processing apparatus.

The machining apparatus 101a proposed in the preparation step for the lapped surface is constituted by the work shelf 2, the up and down steel plates 12, the lifting and lowering devices 13 and the heating steel wire 14 as described above However,

The work shelf 2 is constructed in a planar shape (flat plate) so as to be able to accommodate a folded surface of the hot water mat.

In addition, the elevating and lowering plates 12 are constructed of heat-resistant materials such as gypsum boards that are heat-resistant on the same line above the work shelf 2, and are configured to have the same size as the working shelves.

The lifting and lowering device 13 is connected to the center of the upper portion of the lifting and lowering plate 12 to move the lifting and lowering plate 12 in the upward and downward directions. And a motor having a shaft.

The heating steel wire 14 is composed of a heating steel wire 14 (heater wire) which generates a high heat while having a zigzag shape repeated on the lower surface of the lifting and lowering steel sheet 12, wherein the thickness of the heating steel wire 14 is 5 mm And is spaced apart by a distance of 10 mm from the lower surface of the lifting plate 12.

The heating wire 14 is separated from the heating wire 14 by a plurality of fixing clips 15 at regular intervals (in a zigzag arrangement) on the lower surface of the lifting and lowering plate 12, So that the heating steel wire 14 is fixedly held by the heating wire 15 '' (see FIG. 1).

The mounting portion 15 'is formed by screwing a bolt on the lower surface of the lifting and lowering plate 12, and the mounting portion 15' And the ring portion 15 "is hooked on the heating wire 14 so that the heating wire 14 is spaced apart from the lower surface of the up and down steel plate 12 by a predetermined distance.

On the other hand, although the heating steel wire 14 is not shown in the figure, both ends of the heating steel wire 14 are usually connected to a power supply device to enable high temperature generation.

The lowering and lowering plate 12 is lowered by the lifting and lowering device 13 of the processing apparatus 101a when the lapped surface preparing step is completed as described above to heat the lower surface of the lifting and lowering plate 12 A first heat processing step 102 for inserting the steel wire 14 into the inner side of the overlapping surface 1 at a certain depth to form a pipe inlet 11 '

In the first heat processing step, the up and down steel plates are descended by the ascending and descending devices, that is, they are lowered to the overlapped surface on the work shelf so that the heated steel wires of the up and down steel plates are inserted at a predetermined depth while melting the superficial surfaces by the thermal melting.

Since the heating steel wire is spaced apart at a distance of 10 mm from the bottom of the up and down steel plates while maintaining the temperature of 300 ° C., when the up and down plates are closely attached to the upper surface of the overlapped surface, And at the same time, the zigzag pipe exit port is formed in the same plane as the heating steel wire on the double-sided surface by the heat fusion.

At this time, it is preferable that the pipe entrance formed by the heating steel wire is formed to be 6 to 7 mm, which is slightly larger than the thickness of the heating steel wire by 5 mm. This method can be easily implemented by controlling the feeding speed of the heating steel wire.

When the above first heat processing step is completed, the heating steel wire 14 inserted at a certain depth into the inside of the overlapping surface 1 is fixed for a predetermined time to form a round shape of the outer periphery of the heating steel wire 14 A secondary heat processing step 103 for forming the pipe groove 11 to have a predetermined size, (see FIG. 6)

In the second heat processing step, the heating steel wire inserted into the inside of the double face is held at the same position for 1 minute so that the double face of the outer periphery of the heating steel wire is melted by the high heat and the circular pipe groove is formed. Considering that the diameter is 10 Ø, it is preferable that the pipe groove processed by the above is formed to have a diameter of 8 Ø.

For reference, if a heating steel wire of 5 mm thickness is set at 300 ° C and placed in a cushioning material such as a sponge and held for about 1 minute, a circular pipe groove having a diameter of about 8 Ø is obtained by heat melting around the heating steel wire. The data calculated through the experiment can be adjusted or changed depending on the size of the hot water pipe and the material of the double-sided pipe as necessary.

Further, since the pipe groove formed by the heating steel wire is processed into the same circular shape as the round shape of the hot water pipe, the adhesion of the hot water pipe is improved.

When the above-mentioned second heat processing step is completed, the heating steel wire returning step 104 (refer to FIG. 7) in which the up and down steel plates 12 to be carried are raised and lowered,

The heating wire returning step refers to a home position returning step of lifting up and down the lifting and lowering steel plates to lift the heating steel wire from the double face.

The pipe grooving method of the present invention as described above has the advantage that the pipe grooves can be formed quickly, conveniently, and simply by heat melting using the heated steel wire, and the circular pipe grooves identical to the circular shape of the hot water pipe are formed In particular, in the process of placing the hot water pipe into the pipe groove in the process of placing the hot water pipe in the back process, the pipe groove is slightly smaller than the small pipe entrance and the hot water pipe. The hot water pipe is tightly coupled so that the hot water pipe is advantageously prevented from being moved or separated from the pipe groove during another after-treatment or when using the hot water mat.

Meanwhile, the pipe groove machining method according to the present invention provides advantages such as quickness and efficiency of the entire manufacturing process of the hot water mat and reduction of the unit cost of the hot water mat product by minimizing the facility while reducing the pipe groove machining time to the double face .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. That is, those skilled in the art will appreciate that many modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims.
