Description

Safety door frame cover processing method using a forming machine {The method to product cover of safty door frame}

The present invention relates to a safety door frame cover processing method using a forming machine that can be produced in large quantities by extruding a metal disc through the forming machine. In particular, the cross-sectional structure of the upper and lower extrusion rolls formed in the forming machine is optimally selected to form bent portions on the left and right sides of the metal plate passing through the upper and lower extrusion rolls, and the desired bent portions are completed through the fastest single extrusion rolls. The present invention relates to a safety door frame cover processing method using a forming machine to produce a large amount of cover.

In general, a forming machine is a machine for bending a metal plate through pressing, extruding and pressing to produce a sheet having a desired bent portion.

Therefore, most metal sheets have been produced and used in large quantities through these forming machines. By the way, in the case of such a forming machine, there is provided a vertical extrusion roll that rotates at the same rotational speed from the top and bottom, there is a big difference in the speed of its production depending on how to form the cross-sectional shape of the vertical extrusion roll. That is, when the unnecessary extrusion process is put in, the time and cost of manufacturing are generated, and mass production is impossible.

Therefore, it was most effective to optimally form the shape of the outer cross section of the extrusion roll and to allow the metal plate passing therethrough to be continuously bent to have a desired bent portion. By the way, in the conventional case, if you want to produce a cross section, such as the safety door frame cover produced in the present invention, it could be completed only through about 9 to 15 extrusion rolls. The structure of such a conventional extrusion roll was a method requiring an improvement that unnecessary effort is put into improving the time and cost of product production.

The present invention is to provide a safety door frame cover processing method using a forming machine that can be produced in a large amount by extruding a metal disc through the forming machine.

In detail, the cross-sectional structure of the upper and lower extrusion rolls formed in the forming machine is optimally selected to form bent portions on the left and right sides of the metal plate passing through the upper and lower extrusion rolls, and the desired bent portions are completed through the fastest single extrusion roll. To provide a safety door frame cover processing method using a forming machine to be able to produce a large amount of the frame cover.

Safety door frame cover method using a forming machine according to the present invention, the first step: supplying the metal plate 10 on the plate to the first upper and lower flat extrusion roll 11 of the forming machine 100; Second step: supplying the metal disc 10 to a series of second vertical extrusion rolls 21, the shape of the upper and lower cross-section "

The present invention relates to a safety door frame processing method using a forming machine. Therefore, the processing method of the present invention will be described sequentially with the drawings shown.

1 to 6, the present invention first passes through a first step: supplying the original metal plate 10 on the plate to the first upper and lower planar extrusion roll 11 of the forming machine 100. It is to supply a metal plate rolled like a roll. Stainless steels, which are in the form of thin plates and have no special bends, will be common. And the metal disk 10 wound on the roll is provided to the forming machine 100 of the present invention continuously going through the process of bending repeatedly, it is utilized as the frame cover 60 of the safety door. In the first step according to the present invention, such a general metal disc 10 is supplied to the first upper and lower flat-shaped extrusion roll 11 arranged in the forming machine 100.

This primary up-and-down flat extrusion roll 11 is a cylindrical roll, not provided with a special bent portion or groove on its outer peripheral surface as shown in FIG. The metal disc 10 sandwiched between the top and bottom flat extrusion rolls 11 naturally enters the next secondary extrusion roll 21. It should be noted that the rotational speeds of the upper and lower extrusion rolls must all be the same. If a slight speed difference occurs, slippage with the metal disc 10 may occur and the surface may be damaged.

Next, in the present invention, the metal disc 10, which is the second step, is supplied to a series of second up and down extrusion rolls 21, and the shape of the top and bottom cross sections is "

Therefore, the center of the metal disc 10 remains intact. The left and right ends should be bent to have a certain shape.

However, it is difficult to complete the desired bent portion by only one extrusion of the flat metal disc 10. It must be bent little by little through the repeated process to change the structure to cover the outer circumference of the frame of the safety door. Through this cross-sectional structure, it is bent little by little to produce a continuous product. The present invention achieves the desired object by optimally forming the cross-sectional shape of each of the upper and lower extrusion rolls. Conventional forming machines produce safety door frame covers only by successively passing about 10-15 extrusion rolls.

By the way, in the present invention, all of these processes are omitted, and all operations are completed by simply passing through six extrusion rolls.

In any case, in the second step of the present invention, the metal disc 10 on the plate is pressed by the second up and down extrusion roll 21,

Therefore, while producing a completed safety door frame cover 60, it is possible to mass-produce with a minimum number of extrusion rolls by the combination of the cross-sectional structure of the optimum upper and lower extrusion rolls.

The fourth processing plate 50 enters between the sixth extrusion roll 61 located in front of the fifth extrusion roll 51 described in the above-described process. Therefore, the fourth processing plate 50 passing through the fifth up and down extrusion roll 51 enters between the sixth up and down extrusion roll 61 to completely complete the shape of the bent portion.

In the case of the sixth extrusion roll 61 according to the present invention, the shape of the cross section is formed of recesses and protrusions to bend the fourth processing plate 50. In other words, "

In the sixth step of the present invention, the fourth working plate 50 is pressed by the sixth vertical extrusion roll 61,

Figure pat00035
It is important to make a completed safety door frame cover 60 of the " type. The finished safety door frame cover has a right end bent portion 63 with the flat plate portion 64 compared to the fourth processing plate 50. The connection portion is bent to a greater width to maintain a perfectly vertical line state, such as the end of the left end bent portion 62 to maintain a perfectly horizontal bent state.

As a result, the safety door frame cover of the present invention is completed through the above six steps.

In the present invention, the pair of cutters 70 are brought into close contact with the lower ends of the metal discs 10 supplied to the extrusion roll 11 of the first upper and lower flat shapes of the forming machine 100 in the first step. It is preferable to cut the left and right sides of the scratch prevention wrap 71 attached to the lower end of (10).

That is, as shown in FIGS. 3 and 4, before the metal disc 10 enters the first stage flat extruder 11, a pair of cutters protruding from the lower left and right ends of the metal disc 10 are projected. Is in close contact to cut the wrap (71). The scratch prevention wrap 71 is coated with a close contact from the production of the metal disc 10 because the surface of the cover may be scratched and degraded before the frame cover of the safety door is manufactured and fitted into the frame. Delivered. However, when the wrap 71 is in close contact with the bent end portion and is bent, it may be difficult to peel off in a state where it is fitted to the frame later, and when contacting the frame, the contact portion with another frame cover is overlapped, which may be difficult to work afterwards. have.

In addition, the left and right ends are not particularly likely to be scratched, so the coating is practically unnecessary. Therefore, the frame cover of the present invention is to be cut in advance when bending. Very briefly, before entering the forming machine 100, the cutting is performed by bringing the lower end of the metal disc 10 coated with the wrap 71 onto a pair of cutters projecting from the bottom to the top. And only by holding the end of the cut wrap 71 in accordance with the transfer of the upper and lower extrusion roll 11 of the forming machine 100 is naturally peeled off. In the case of FIG. 4, the anti-scratch wrap 71 is peeled off from both ends.

Next, in the case of the present invention, the safety door frame cover 60, which is completed through the sixth step and is extruded into the guide rail 85, is cut into a suitable size through the hydraulic press cutter 80 operating in the vertical direction. The upper end portion 75 of the right end bent portion 63 is preferably partially cut through the hydraulic press cutter 90 operating in the left and right directions.

In the case of the safety door frame cover that completed the bending of the present invention, the metal disc 10 entered in the form of a roll is continuously bent through the forming machine 100 to be produced. That is, it is not extruded in a state of being cut to a constant size. The frame cover with this cross section must be cut to fit the frame size of the door or window. Therefore, in the present invention, as shown in Figures 5 and 6, to complete the cross section through the forming machine 100 is to cut through the hydraulic press to move the frame cover. Hydraulic press cutter 80 with a cutter at the top of the frame cover coming out through the conveying conveyor 85 is to cut to a suitable size while lowering the cutter 80 to a high pressure.

Of course, the frame cover of the present invention is not provided with only the hydraulic press cutter 80 in the vertical direction. As shown in FIG. 6, the hydraulic press cutter 90 has a separate hydraulic press cutter 90 that cuts the bent portion of one end by pressing the hydraulic press force in the lateral direction from the side. Accordingly, the hydraulic press cutter 90 in the left and right directions cuts a part 75 of the right end bent portion 63 described above. The cut portion 75 of the right bent portion 63 shown in FIG. 6 may be cut because this portion may be an interview with another frame cover, but should be a space for the lock to protrude or a key to be inserted. The cutting is completed in advance.
