Since the punch 16 is in contact with the lower surface of the upper base 15 from the lower side, the punch 16 is located at an upper position where it is separated from the die 25 while being immersed in the guide hole 15 a of the upper base 15. ing.
- the ejector plate 31 is located at a position where the upper end of the ejector plate 31 is at substantially the same height as the upper end of the die 25 due to the pressing force of the urethane spring 27.
- the striker 14 When the steel plate 5 is positioned between the punch 16 and the die 25 while the striker 14 is moving upward, the striker 14 is moved downward, as shown in FIG. 16 moves downward and protrudes downward from the guide hole 15a of the upper base 15 and is pressed by the punch 16 and the die 25 moved downward, so that the bulging portion 7 is formed on the steel plate 5. Molded. At this time, the ejector plate 31 moves downward by being pressed by the punch 16 via the steel plate 5, but as the punch 16 moves upward after the bulging portion 7 is formed, the urethane spring 2 It operates to move upward by the pressing force of 7 and remove the steel plate 5 from the die 25.
- the second mold device 11 is a device for forming a concave portion 8 and a drain passage 9 in the bulging portion 7 formed by the first mold device 10,
- the device 11 is also provided with a punch assembly 32, a diassy 33, and a striker 34 similarly to the first mold device 10 described above.
- the punch 32 and the flange 36 are integrally formed on the upper end of the punch guide 36. a, a stripper plate 38 fixed to the lower end of the punch guide 36 via a stopper bolt 37, with the punch guide 36 and the upper end protruding upward from the flange 36a.
- the above-mentioned dashes 33 are dents 45 for forming a concave portion and a drainage passage fixed to the lower base 44, and stripper bolts 4 6 similar to those of the above-described first mold apparatus 10.
- It consists of a spring 47, upper and lower collars 48, 49, and an ejector plate 50.
- the second mold apparatus 11 is configured such that the support body 42 held at a predetermined position by the urging force of the spring 43 as shown in FIG. Since the punch guide 36 comes into contact with the part 36 a from below, the punch guide 36 comes out of the die 45 in a state where the stripper plate 38 enters the guide hole 35 a formed in the upper base 35.
- the punch 39 is immersed in the bore portion 38 a of the stripper plate 38 by the biasing force of the stripping spring 40.
- the ejector plate 50 is located at a position where the upper end of the ejector plate 50 is substantially at the same height as the upper end of the die 45 due to the pressing force of the urethane spring 47.
- the striker 34 When the striker 34 is moved upward, the bulging portion 7 of the steel plate 5 is positioned between the punch 39 and the die 45, and then the striker 34 is moved down.
- the punch 39 and the punch guide 36 move down together, whereby the stripper plate 38 projects downward from the guide hole 35a of the upper base 35 and abuts the upper surface 5a of the steel plate 5, The upper surface 5a of the steel plate is pressed by the stripper plate 38.
- only the punch 39 moves downward, and the concave portion 8 and the drain passage 9 are formed in the bulging portion 7 by the punch 39 and the die 45 moved downward.

- the shearing surfaces 8a and 9a have a high protrusion height from the upper surface 5a of the steel plate by the height of the bulging portion 7, and the upper edge portion has an acute angle. Excellent anti-slip effect can be exhibited.
- the angle formed between the shear surfaces 8a and 9a and the upper surface of the bulging portion 7 becomes acute as the gradient angle of the bulging portion 7 increases, and as the angle increases, the shearing surfaces 8a and 9a increase.
- a sharp edge can be formed at the upper edge of a, and the anti-slip effect can be further improved.
- the shearing surfaces 8a and 9a are formed in a half-blanked state so that no through hole is formed in the steel plate 5, a double structure is formed as in the case where the conventional through hole is formed. Without this, it is possible to avoid problems such as water or slag entering the inside of the cover 2-3, the hot air from the engine, and the diffusion of noise to the outside. Achieve down. Further, in this case, since the drainage path 9 is formed as an inclined surface, it is possible to prevent water and mud from accumulating in the concave portion 8 and impair the anti-slip effect. It is easy to clean even if dirt and trash accumulate in the drain passage 8 and the drain passage 9, and the groove side surface of the drain passage 9 is formed with the shear surface 9a. There is also an advantage that the effect can be further enhanced.
- the anti-slip portion 6 has a high anti-slip effect and does not have a through-hole in the steel plate 5.
- the first die device 10 expands. After the first step of forming the protrusion 7, the second step of forming the recess 8 and the drainage path 9 in the second mold apparatus 11 is performed.
- the swelling portion 7 can be formed sufficiently high, and the stress acting on the steel plate 5 when the swelling portion 7 is sheared in a half-punched state can be reduced, and the shearing surfaces 8a, 9 A sharp edge can be set on the upper edge of a, and Thus, an excellent anti-slip effect can be exhibited.
- the present invention is used for treads of construction machinery, floors and passages of building structures, stairs, floors and steps of buses and trucks, special vehicles, etc., decks and decks of railway vehicles, ships, etc., erection floors at construction sites, etc.
- the present invention can be widely applied in the technical field of a method and a device for producing a non-slip material of various scaffolds requiring a non-slip.
- the invention can also be used in places where a problem occurs when a through-hole is opened, and when it is desired to easily produce a non-slip material having a high anti-slip effect that is easy to clean. It is useful when
