The present invention relates to an automatic fire extinguishing pipe manufacturing apparatus equipped with a branch pipe, wherein the branch pipe is automatically formed and the branch pipe is automatically welded to the branch part, thereby improving the production speed of the branch pipe. It relates to an automatic manufacturing device for fire extinguishing pipes.

A fire extinguishing pipe is a pipe installed indoors of a building, and in the event of a fire, it is a piping facility for suppressing a fire by supplying fire extinguishing water to the fire extinguishing pipe and spraying the fire extinguishing water through a sprinkler.

1 is a view showing a general fire extinguishing pipe (1). The fire extinguishing pipe 1 shown in FIG. 1 includes a body part 1a through which fire extinguishing water flows, a shaft pipe part 1b formed at one end of the body part 1a, and a main pipe or nipple or It includes branch parts T1, T2, T3 to which branch pipes such as branch pipes are connected.

Fire extinguishing water flows inside the body portion 1a. The shaft pipe part 1b formed on one side of the body part 1a is connected to another fire extinguishing pipe having the same diameter as the shaft pipe diameter, and is finally sealed with an end cap. A branch pipe may be connected to the branch portions T1, T2, and T3, and a sprinkler for spraying fire extinguishing water may be connected to the branch pipe.

The branch portions T1, T2, and T3 are generally formed by drilling a hole in the body portion 1a with a drill, then inserting a drawing mold into the body portion 1a to position the hole in the hole, and remove the drawing machine from the outside of the hole. After bonding to the drawing mold, the drawing mold is drawn through a hole and formed by plastic working.

Thereafter, the surfaces of the branch portions T1, T2, and T3 are polished through a chamfering process to finally form the branch portions T1, T2, and T3. The branch portions T1 , T2 , and T3 formed in this way are generally referred to as a T branch or a T draw or branch tee in the industrial field.

However, the process of inserting the drawing mold into the body portion 1a to form the branch portions T1, T2, and T3 requires a guide for inserting the drawing mold into the body portion 1a, and the operator guides the hole to the inside of the body portion 1a. Since it is necessary to position the drawing mold using

In addition, in order to draw out the drawing mold through the hole, an operator must manually couple the drawing machine to the drawing die and operate the drawing machine again, so there is a problem in that the production speed is greatly reduced.

In particular, like the fire extinguishing pipe 1 shown in Fig. 1, the position of the specific branch portion T3 is not located on a straight line with the other branch portions T1 and T2, but is formed at a position forming a predetermined angle θ. In this case, there is a problem in that the production speed is greatly reduced.

That is, in the case of a specific branching portion T3 forming a predetermined angle θ with the other branching portions T1 and T2, a predetermined angle θ with respect to the other branching portions T1 and T2 positioned on a straight line Since the branch has to be formed on the left or right side, the operator must first manually mark the location where the branch is to be formed, and after processing of the other branch parts T1 and T2 is completed, manually rotate the fire extinguishing pipe 1 to create a specific branch (T3) has to be processed again, so there is a problem in that the production speed is significantly reduced.

In particular, when the location of the specific branch T3 is displayed, as the operator manually marks the location, confusion about the left and right sides occurs, resulting in a dormant error in which the location indication is incorrect, resulting in a problem that the product must be discarded. also do

Hereinafter, an operation of the automatic fire extinguishing pipe manufacturing apparatus provided with a branch pipe according to an embodiment of the present invention will be described with reference to FIGS. 8 to 13 .

First, the user arranges the front end of the fire extinguishing pipe 1 on the moving die 10 , and arranges the rest of the fire extinguishing pipe 1 to be supported by the support die 97 . At this time, the user arranges the reference position (A) of the fire extinguishing pipe (1) to be gripped by the movable die (10).

Here, the reference position (A) is a starting point for calculating the processing dimensions of the fire extinguishing pipe (1) when the fire extinguishing pipe (1) is processed in the automatic fire extinguishing pipe manufacturing apparatus provided with the branch pipe. In this case, the hydraulic chuck module 110 of the moving die 10 may be provided with a guide (not shown) to which the reference position A of the fire extinguishing pipe 1 is coupled.

The user inputs the input unit 80 to the position of the first branching portion T1, the number of branching portions, the interval L between each branching portion T1, T2, and T3, and the angle formed by each branching portion T1, T2, T3. When the design dimensions of the fire extinguishing pipe (1) such as (θ) are input, the control unit 70 sets the processing dimensions of the fire extinguishing pipe (1).

For example, the fire extinguishing pipe 1 shown in Figure 1, the user through the input unit 80, the first branch (T1), the position of the first branch (T1), the distance between each branch (L), When the design dimensions of the fire extinguishing pipe 1 such as the angle θ formed by the second branch T2 and the third branch T3 are input, the control unit 70 controls the fire extinguishing pipe 1 according to the input value. Set the machining dimension. Here, the processing dimensions of the fire extinguishing pipe 1 may be set based on the above-described reference position (A).

The control unit 70 controls the hydraulic chuck module 110 . The control unit 70 sends a control signal to the hydraulic chuck module 110 to hold the fire extinguishing pipe 1 . In this case, the controller 70 operates the hydraulic pump 112 so that the jaws 113 of the hollow hydraulic chuck 111 perform a gripping operation.

Thereafter, the control unit 70 moves the moving die 10 holding the fire extinguishing pipe 1 according to the control signal. In this case, the control unit 70 controls the movement control module 20 so that the movement die 10 is moved forward. The control unit 70 may control the movement control module 20 to move the fire extinguishing pipe 1 to a preset position where the first branch is formed.

The control unit 70 controls the movement control motor 210 of the movement control module 20 . The movement control motor 210 may rotate the screw shaft 220 by a preset number of revolutions according to a control signal from the controller 70 . The movement control motor 210 rotates the screw shaft 220 to move the base plate 120 to a preset position.

The control unit 70 controls the movement control motor 210 so that the drill device 30 is positioned at the position where the branch portions T1, T2, and T3 are to be formed according to the processing dimensions of the fire extinguishing pipe 1 to finally move the die. (10) is moved.

The controller 70 may control the support die 97 when the moving die 10 grips and moves the fire extinguishing pipe 1 . The support die 97 clamps the fire extinguishing pipe 1 according to the control signal of the control unit 70 so that the fire extinguishing pipe 1 is gripped by the moving die 10 and moved in the front-rear direction according to the embodiment. ) or to unclamping.

When the fire extinguishing pipe 1 is moved to a preset position where the first branch portion T1 is to be formed by the moving die 10, the drilling process is performed. Referring to FIG. 8 , the drill device 30 descends into the fire extinguishing pipe 1 in the drilling process. The drill device 30 is operated according to a control signal of the control unit 70 . The drilling device 30 forms a branch hole at a machining position according to the machining size of the fire extinguishing pipe (1). The drill device 30 processes the branch hole to a diameter into which the drawing device 40 can be inserted. When the processing of the branch hole is completed, the drill device 30 may rise to the initial position.

When the drilling process is completed, the control unit 70 controls the movement control motor 210 of the movement control module 20 again. The moving die 10 moves forward as shown in FIG. 9 to position the branch hole in the drawing device 40 . The drawing device 40 forms the branch hole of the fire extinguishing pipe 1 formed by the drill device 30 into a branch after the drilling process.

The drawing device 40 may be operated according to a control signal from the control unit 70 . In the drawing process, the support guide 93 operates according to a control signal from the controller 70 . The support guide 93 supports the fire extinguishing pipe 1 . In this case, the support guide 93 may be located at the front and rear of the branch hole, respectively. The support guide 93 supports the fire extinguishing pipe 1 in the drawing process, and prevents the fire extinguishing pipe 1 from being separated or displaced during the drawing process.

In the drawing process, as shown in Fig. 10 (a), the drawing device 40 descends into the fire extinguishing pipe 1 according to the control signal and is inserted into the branch hole. As described above, the elevating cylinder 320 is disposed in a position in which the expansion weight 340 is pushed to the maximum. That is, as shown in (a) of FIG. 6 , the diameter D1 of the bottom surface of the drawing mold 330 is minimized and inserted into the branch hole.

Then, as shown in Figure 10 (b), the drawing mold 330 is expanded. As described above, the elevating cylinder 320 pulls the expansion weight 340 according to the control signal. When the elevating cylinder 320 pulls the expansion weight 340 , the expansion head 343 is drawn into the drawing mold 330 .

In this case, the diameter (D2) of the drawing mold 330 is expanded in the direction of the outer circumferential surface as described above. That is, the mold pieces 331 of the drawing mold 330 are spaced apart as much as possible from each other as shown in FIG. .

Then, as shown in FIG. 10( c ), the drawing mold 330 having the diameter D2 of the bottom surface is drawn out from the branch hole. When the drawing mold 330 is drawn from the branch hole, the edge of the branch hole is in contact with the curved portion 333 formed on the outer circumferential surface of the drawing mold 330 . In this case, the expansion head 343 may be disposed in the recessed portion to support the mold pieces 331 from sliding inward again.

The curved part 333 draws out the edge of the branch hole as the drawing device 40 rises, and is formed into a branch part protruding upward. When the drawing device 40 is completely separated from the fire extinguishing pipe 1 and the forming of the branch is completed, the drawing device 40 may rise to the initial position.

In this case, in the drawing process according to the prior art, the production speed is greatly reduced because the worker manually places the drawing mold in the branch hole and draws it after coupling. Without the drawing device 40, as described above, it automatically operates to form a branch hole, so the production speed is greatly improved.

Again, the control unit 70 controls the movement control motor 210 of the movement control module 20 . The moving die 10 is moved forward as shown in FIG. 11 , to position the branch in the chamfering device 50 .

The chamfering device 50 is operated according to the control signal of the control unit 70 . In the chamfering process, the chamfering device 50 descends to the fire extinguishing pipe 1 to chamfer the surface of the branch of the fire extinguishing pipe 1 . The chamfering device 50 removes the burr etc. formed on the surface of the branch and processes it into a flat surface. When the chamfering process is completed, molding of one branch is completed.

The control unit 70 may sequentially process the first branching part T1 and the second branching part T2 shown in the fire extinguishing pipe 1 shown in FIG. 1 according to the set processing dimensions of the fire extinguishing pipe 1 . have. The control unit 70 controls the hydraulic pump 112, the movement control motor 210, the elevating cylinder 320, the drill device 30, the drawing device 40, etc. according to the set processing dimensions of the fire extinguishing pipe 1 Thus, the first branching portion T1 and the second branching portion T2 are automatically formed.

Accordingly, when the user inputs the design dimensions of the fire extinguishing pipe 1 at once through the input unit 80, the control unit 70 sets the processing dimensions and then automatically performs the drilling process or the chamfering process for the fire extinguishing pipe 1 Since the branch is formed, the production speed is remarkably improved compared to the existing manual operation.

In addition, the automatic fire extinguishing pipe manufacturing apparatus provided with the branch pipe of the present invention can automatically mold the third branch portion (T3). When the angle θ formed by the second branching part T2 and the third branching part T3 is input to the input part 80 , the controller 70 controls the fire extinguishing pipe 1 so that the third branching part T3 is formed. ) is rotated.

In this case, as described above, the control unit 70 rotates the rotation control motor 119 . The rotation control motor 119 receiving the control signal rotates the gear unit 117 to rotate the hollow hydraulic chuck 111 by a preset angle θ according to the processing dimensions of the fire extinguishing pipe 1 .

When the hollow hydraulic chuck 111 is rotated, the fire extinguishing pipe 1 held by the hollow hydraulic chuck 111 is rotated by a preset angle θ. In this case, the rotation control motor 119 rotates the fire extinguishing pipe 1 by a preset angle θ so that the drill device 30 can process a hole at the position B where the branch hole is to be formed.

That is, when the angle θ formed by the second branching portion T2 and the third branching portion T3 is, for example, 90°, the user inputs this as the design dimension of the fire extinguishing pipe 1 . 11 to 12, when the position (B) where the branch hole is to be formed is at a position of 90° with respect to the upper surface of the fire extinguishing pipe, the control unit 70 controls the rotation control motor ( 119) is rotated to rotate the gear unit 117, and the hollow hydraulic chuck 111 connected to the gear unit 117 is rotated by 90°, which is a preset angle (θ). The fire extinguishing pipe 1 is rotated by the hollow hydraulic chuck 111 by 90°, which is a preset angle θ, so that the drill device 30 can contact the position B where the branch hole is to be formed.

Thereafter, the drill device 30, the drawing device 40, and the chamfering device 50 perform the above-described drilling process or chamfering process according to the control signal of the controller 70 to form the second branching part T2 and a predetermined angle ( The third branch portion T3 is automatically formed at a position where θ) is formed.

Accordingly, when the user inputs the design dimensions of the fire extinguishing pipe 1 at once through the input unit 80, the third minute forming a predetermined angle θ with the first branching part T1 or the second branching part T2 Since the base T3 is automatically molded, the dormancy error is eliminated and the production speed is remarkably improved.

Here, the order of the first branching part T1, the second branching part T2, and the third branching part T3 shown in FIG. 1 is arbitrary, and a predetermined angle θ with respect to the reference position A The branch in which is formed may be formed first, or may be formed in the middle.

The control unit 70 controls the movement control motor 210 of the moving agent module for the shaft pipe process after the processing of the first branching part T1 to the third branching part T3 is completed. The control unit 70 moves the moving die 10 to arrange the front end of the fire extinguishing pipe 1 on which the shaft pipe part 1b is to be formed as the shaft pipe device 60 .

The control unit 70 controls the support press 61 to grip the front end of the fire extinguishing pipe 1 . In this case, the control unit 70 controls the hydraulic chuck module 110 so that the jaw 113 grips the fire extinguishing pipe 1 so that the fire extinguishing pipe 1 is firmly supported.

When the support press 61 grips the fire extinguishing pipe 1 , the control unit 70 operates the accumulator 63 . The accumulator 63 reduces the diameter D1 of the front end of the fire extinguishing pipe 1 while drawing the front end of the fire extinguishing pipe 1 to the inside. When the axial pipe process is completed, the molding of the fire extinguishing pipe 1 in which the branch parts T1 , T2 , T3 and the axial pipe part 1b are formed as shown in FIG. 1 is completed.

Accordingly, when the user inputs the design dimensions of the fire extinguishing pipe 1 at once through the input unit 80, the control unit 70 sets the processing dimensions and then automatically performs the drilling process or the chamfering process for the fire extinguishing pipe 1 Since the first branching portion (T1) to the third branching portion (T3) and the shaft tube portion (1b) are molded, the production speed is remarkably improved compared to the conventional manual operation.
