Abstract

PURPOSE:To form an accurate corrugation by inserting a punched wire mesh between a lower die and a movable upper die, by pressing each die member composing the movable die successively from one end to the direction of bitting with a press bar to bend the punched wire mesh. CONSTITUTION:The punched wire mesh A is mounted on the lower die 3, a hydraulic cylinder 9 is operated to descend the movable upper die 8 along a guide plate, the top end of the die member 12 is abutted lightly on the punched wire mesh A. A hydraulic cylinder 21 is operated to advance the press bar 15 along a guide rail 16 and an upper guide piece 19 in the direction of the movable upper die 8. The die member 12 of the movable upper die 8 is gradually pressed to the biting direction while it is guided by the press guiding plane 17 of the press bar 15, while bending the punched wire mesh A to bite a die member 5 of the lower die 3 successively and to form the corrugation on the punched wire mesh A. In this way, without generating the deformation of the meshes of the punched wire mesh or a break, the accurate and uniform wire mesh is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a corrugating processing apparatus particularly suitable for processing punched wire meshes, thin plates, etc. into corrugated shapes.

[Conventional technology and its problems]

Conventional 1: For example, when corrugating a punched wire mesh used for a ventilation fan filter, etc., a punched wire mesh of the required width is sandwiched between the IlH of a corrugated lower mold and a movable upper mold, and the movable upper mold is moved in the mating direction. There is a known device that applies pressure to create corrugations.

However, in the conventional apparatus described above, the punched wire mesh is squeezed downward at once by applying pressure from a movable upper mold to form a wave shape, so that the mesh of the wire mesh becomes uneven due to the squeezing.
In addition, it is easily broken and has the disadvantage that it is difficult to reliably form a uniform corrugated wire mesh at all times.

The present invention aims to solve the problems of conventional bags at once and provide a corrugated material processing device that can always reliably form a uniform and highly accurate corrugated wire mesh.

[Means for solving problems]

That is, in the present invention, a lower die 3 having a corrugated surface shape and a movable upper die 8 are disposed so as to be able to fit together freely, and the movable upper die 8 is disposed so as to be freely interlocked with each other. Reference numeral 18 is composed of a required number of plate-shaped mold members 12 each having a chevron-shaped tip and arranged side by side so as to be vertically slidable, and the mold members 12 are sequentially fitted to one end of the movable upper mold 8 in the mating direction. A press bar 15 is provided so as to be able to move in and out.

[For production]

A punched wire mesh A is sandwiched between the lower mold 3 and the movable upper mold 8, and each mold member 1 constituting the movable upper mold 8 is moved by a press bar 15.
2 in the interlocking direction from one end to hold the mesh together while bending the punched wire mesh A to form a corrugated shape.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below.

1 is a table with legs, 2 is a lower mold holder mounted on the table l, 3 is a wavy surface-shaped lower mold held on the lower mold holder 2, and the lower mold 3 is a rectangular shape that can be assembled freely. It is constructed by arranging a required number of plate-shaped mold members 5 having mountain-shaped tips in parallel in a mold 4. Reference numeral 6 denotes an elongated upper mold holder disposed above the lower mold holder 2 and facing each other via a support 7, and 8 is provided on the lower surface of one end of the upper mold holder 6 via a fluid pressure cylinder 9 so that it can be raised and lowered. The movable upper mold 8 has a wavy surface shape, and the movable upper mold 8 can be freely engaged with the lower mold 3.

As shown in FIGS. 2 and 3, the movable upper mold 8 is fitted with a required number of locks each having a chevron-shaped tip in a rectangular mold frame lO provided with locking steps 11 on one side inner wall. It is constructed by locking plate-shaped members 12 with ears 13 in parallel so as to be vertically slidable. Reference numeral 14 denotes a guide plate for the movable upper mold installed vertically on the lower surface of the upper mold holder 6, and 15 denotes the movable upper mold 8.
The press bars 15 are movable and press each mold member 12 of the second mold 8 sequentially in the mating direction. Its length and height are set appropriately so that it can fit into the lower mold 3. 17 is an inclined pressure guide surface formed at the tip of the pressure bar 15; 1B is a roller embedded in the tip of the pressure bar 15 so as to slightly protrude toward the lower surface and the pressure guide surface 17; 19 and 20; 21 is a hydraulic cylinder connected to the rear end of the pressing bar 15. In addition, A indicates a punched wire mesh before processing, and B indicates a corrugated punched wire mesh after processing.

Next, the operation of this embodiment will be explained.

First, a punched wire mesh Att of the required width is placed on the lower mold 3 (see Fig. 3).Then, the fluid pressure cylinder 9 is activated, the movable upper mold 8 is lowered along the guide plate 14, and the mold is removed. Lightly bring the tip of the member 12 into contact with the punch mIA (see Figure 4).At this time, as shown in Figure 5, each mold member 12 of the movable upper mold 8 is locked with the mold frame 10. has come off, and a slight gap is created between the locking step portion 11 and the locking lug 13. After that, fluid pressure cylinder 2! , and press the press bar 15 against the guide rail 1B and the upper guide piece 1.
The movable upper mold is moved forward in the 8 direction along lines 9-20. Then, the pressure bar! The mold member 12 of the movable upper die 8 is gradually pressed in the engagement direction while being guided by the pressing guide surface 17 of the movable upper die 8, and the die member 12 of the movable upper die 8 is successively engaged with the die member 5 of the lower die 3 while bending the punching wire mesh A. along with forming it into a waveform,
The lower surface of the pressing bar 15 is pressed and held in a mating state (
(See FIG. 6), and at this time, the mold members 5 and 12 are properly engaged by locking the locking ears 13 of the mold member 12 with the locking steps 11 of the mold frame 10. .

Thereafter, the press bar 15 is moved forward at a constant speed, and the mold member 5.!
The two pieces are joined together to form the punched wire mesh A into a corrugated shape.

When the lower die 3 and the movable upper die 8 are completely engaged, the hydraulic cylinder 21 is operated to move the press bar 15 back and return it to its original state. Next, the fluid pressure cylinder 9 is operated to move the movable upper mold 8 to the upper A, and the lower part 53 is disengaged, and the corrugated punched wire mesh B (see No. 7 UgJ) is taken out.

Thereafter, the movable upper die 8 and the lower die 3 may be fitted together by the same operation to form the punched wire mesh A into a corrugated shape.

In the above embodiment, the lower mold 3 is disposed at the bottom, and the movable upper mold 8 is disposed at the upper part.

Of course, the arrangement may be reversed. Further, the lower mold 3 is formed by arranging a required number of plate-shaped mold members 5 having chevron-shaped tips in parallel, but it may be constructed as one piece.
