A runner processing step in which a desired zinc iron plate is wound in a coil shape, and the coil plate is formed into a U-shaped runner through a forming machine; A notch slitting step of forming a notch slit portion at equal intervals on the bottom of the runner via a U-shaped cutter after the processing step, and a squeezing step of forming a curved squeezed portion on one side surface of the runner after the notch slitting step And automation of each process consisting of
As a result, it is possible to easily and easily mold the slit portion and the squeezed portion on the runner integrally molded in a U-shape.

Further, according to the configuration of the runner of the present invention, in the case of performing R processing under computer control, a step of forming a U-shaped runner in a roll, a step of feeding a front ear, a step of repeating a press from a slit press step and a press repetition. In the process, an operation of performing a slit press process on the bottom of the runner, an operation of performing a press operation on one side of the runner at the notch slit portion, an operation of feeding a number of pitches after these operations, and the slit press / press In each step consisting of a press repetition step of repeating each operation of press and pitch feed, a feed step of the rear ear after this step, and a front and rear ear cutting step of cutting the front ear and the rear ear to a required length, processing Product length, R size, number of rolls , ear length,
Since the number of notch slits, the number of R- shaped squeezes, and the pitch of the notch slits were input to the computer, the material of the runner wound in a coil shape was changed based on these processes. By controlling a computer on the runner formed in a letter shape, slitting and squeezing can be performed automatically and in a continuous process.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wall material runner according to the present invention will be described below with reference to the drawings. 1 to 3
1 illustrates a runner 1 of the present invention and a molding process thereof. As shown in FIG. 1, the runner 1 obtained by the R processing method has a notch slit portion 3 on the bottom of a zinc iron plate integrally formed in a U-shape and a squeezed portion 4 on one side as shown in FIG. It is molded at equal intervals, and the whole is curved and formed in an R shape on the squeezed portion 4 side.

[0008] The R-processed runner body thus integrally molded is molded by a process as shown in FIG. First, a desired zinc-iron plate wound in a coil shape is provided, and then the coil plate is formed into a U-shaped runner through a forming machine.
And a notch slit forming step (c) in which, after the runner forming step, a notched slit portion is formed at the bottom of the runner via a U-shaped cutter. Squeezing step (d) for forming a squeezed portion. Note that the size of the runner material shown in FIGS. 3 and 4 is 45 mm to 100 m.
The m-size one is the optimal size.

FIGS. 4 and 5 show a partially enlarged portion of slitting and squeezing of the runner of the present invention.
FIG. 4 shows the slit processing part, and FIG. 5 shows the squeezing processing part. FIG. 6 shows a cross section of the R runner of the present invention which has been subjected to the R processing.

The R-forming runner 1 of the present invention thus formed is processed by an automatic molding process controlled by a computer as shown in FIG. That is, a step of roll-forming a U-shaped runner, a step of feeding a front ear, an operation of performing notch slit press processing on the bottom of the runner, and an R- shaped squeezing press on one side of the runner at the notch slit portion. A press repetition step of repeatedly performing an operation of performing processing and an operation of feeding an amount of pitch after these operations, a rear ear feeding step of forming a rear ear after the step, and the front ear and the rear ear are required. It consists of the front and rear ear cutting process, which cuts to length, and the length of the processed product, the size of R, and the low
By inputting the number of holes, the length of the front ear, the number of notch slits, the number of R- shaped squeezes, and the pitch of the notch slits into a computer, the product can be commercialized from runner material wound in a coil shape. Can be automatically and continuously performed by computer control.

In the embodiment of the present invention configured as described above, the runner body 1 has a notch slit 3 at the bottom of a zinc-iron plate integrally formed in a U-shape and a wrung portion 4 on one side. Since it is configured to be formed at intervals and in an R shape, when forming it, a desired zinc iron plate wound in a coil shape is provided, and the coil plate is formed into a U-shape through a forming machine. A runner forming step for forming the runner into a runner, a notch slit forming step for forming a notch slit portion at an equal interval at the bottom of the runner via a U-shaped cutter after the runner processing step, and a runner after the notch slit forming step. And a squeezing step of forming an R-shaped squeezed portion on the side surface, so that the slit portion 3 and the squeezed portion 4 can be easily and easily formed on a runner integrally molded in a U-shape. Can mold processing, it can be curved in an R shape to the machining unit 4 side aperture whole.

In addition, with this configuration, a notch slit press process is performed on the bottom of the runner in the steps of forming the U-shaped runner in a roll, forming the feed of the front ear, and performing the slit pressing step to the pressing repetition step. A press repetition step of repeatedly performing an operation, an operation of performing an R- shaped squeezing press process on one side of the runner, and an operation of feeding a pitch after these operations, and a rear ear for forming a rear ear after the process In the feed process, and the front and rear ear cutting process of forming the front and rear ears based on the input information for cutting the front and rear ears, the runner material wound in a coil shape is formed into a U-shape. By controlling the computer on the runner that was set, it was possible to perform slitting and squeezing by automatic and continuous processes, The processing unit 4 side aperture body can be curved in an R shape.

[0013]

According to the present invention, the runner body 1 is bent into a U-shape,
The runner main body 1 is provided with a plurality of notch slits 3 which are cut out at intervals at the bottom thereof, and a plurality of squeezed portions 4 which are drawn on one side corresponding to the notch slits.
Is provided, and the whole is curved and formed in an R-shape on the side of the squeezing portion 4, so that it is possible to have a form optimal for automation, and to a runner integrally molded in a U-shape. The slit portion 3 and the squeezed portion 4 can be formed easily and easily, and the entire portion can be curved and formed in an R shape on the squeezed portion 4 side.
