Description

[Detailed Description of the Invention] (a) Industrial Application Field This utility model relates to a craft fan.

(B) Conventional technology For the processing of the fan frame, a foot called punch is punched in the key part of the fan frame with a foot-punch type punch. Using this memoi, combine the bamboo sticks that fit into the holes of the memomi called higo and combine the number of fan bones that can be processed, fix both sides with both feet and use the special blade to attach the fan bones. Finished in shape. The shape is not constant and may vary from order to order. It takes a considerable number of days to perform a trial shape matching each time and reach a satisfactory fan frame, and it is impossible to obtain a stable shape. Recently, punching using a punch using a press has been adopted, and the shape of the fan frame has been processed in two steps one by one. For this reason, there is an advantage that the finishing time for filling is considerably shortened. However, especially for medium filling, the daily production volume is about 13,000, although there are some differences due to human labor. Recently, due to the shortage of engineers and the advancement of the age, the production amount is decreasing more and more. Also in the press, if the machinability is poor due to the contact processing, it causes defects and cracks in the cut surface, and has a drawback that greatly affects the subsequent steps.

(C) Problems to be solved by the utility model Using the ultra-high-pressure water jet, which has recently attracted particular attention, it has a very small nozzle diameter of 0.15 mm and is non-contact, resulting in a smooth cutting surface. With a few cutting margins, it is easy to touch, has a good texture, and has a high commercial value. It has a stable quality, with multiple rows, and with any number of stacks, it is jet cut into any shape by NC control. It enables the production amount commensurate with.

(D) Means for solving the problem: A pallet 12, 6 to 11 in a series of multiple rows in which a holding head having a jet receiving device is set is assembled with an arbitrary number of stacked fan frames, and a clamp conforming to the shape of the fan frame is clamped. Position and press the pallet to the clamper with the jig attached and fix it. This is a cutting device provided with a jig for cutting into an arbitrary shape with an ultra-high-pressure water jet, and a processing device that simultaneously performs drilling of a memo memo with a drill.

(E) Action By automatically supplying the desired number of fans to the pallet, they are continuously conveyed, fixed in position, drilled, cut, automatically released, carried out, and the fan body and scrap are automatically identified, and Continuous production process.

(F) Example An example of the present utility model will be described with reference to a cutting device that uses an ultra-high pressure water jet as a manual cut for cutting an arbitrary shape of a fan frame.

The pallet (1) that is automatically loaded is composed of an assembly in which a holding head (2) having a jet receiving device is fixed by bolts (3).

A fan frame (9) is stored in the pallet (1) by the number of sheets required to be processed. This pallet (1) is composed of a clamper (5) in which a clamp jig (4) conforming to the shape of a fan is fixed with bolts (6) and a positioning pin (10) set in the clamper (5). In the clamp part that has been fixed, the vertical device (13) is activated by stopping at a fixed position, and the pallet vertical plate (16) fixed to the guide shaft (14) is lifted using the guide holder (15) as a guide. Then, the fan (9) is attached to the clamp jig (4),
It will be fixed in real time. As a result, there is no misalignment or fraying for overlapping cutting of the fan frame (9), and it is possible to drill and cut holes having a smooth cross-section with a good feel. This apparatus is shown in FIG. 1 in which the pallet has been conveyed and is in a fixed position, and FIG. 2 is a cross-sectional view in which the pallet is lifted and fixed in a fixed position, and the fan frame is fixedly fixed. Is.

FIG. 3 shows a state in which the pallet (1) is stopped at the processing position, lifted by the vertical device (13), and fixed by the clamper (5) and the positioning pin (10).
The state where a hole is drilled by a drill (12) attached to the machining head (11) is shown.

FIG. 4 shows a state in which the pallet (1) is in a fixed position and a state after carrying out processing and before carrying out to the next step.

Fig. 5 is a front view of the transport and clamp parts, and the pallet (1)
Shows the state where is clamped.

FIG. 6 shows a part of the reciprocal sequence in which the fan frames (9) are supplied and housed in the pallet (1) by the number of overlapping sheets.

FIG. 7 shows a part of the reciprocal sequence when the pallet (1) is positioned and fixed and is drilled by the drill (12).

FIG. 8 shows a part of the reciprocal sequence in which the pallet (1) is positioned and fixed, and the outer circumference of the fan is cut into a set shape by the ultrahigh pressure water jet of the nozzle (7). 3 is a cross-sectional view showing a state of a fan frame in a pallet cut by a jet.

(G) Effect of utility model With a simple mechanism that installs a cutting device that uses a commercially available ultra-high pressure water jet, it can cut any shape and produce any quantity in combination with NC control, and Stabilization and cost reduction are both significant, and the effect of obtaining a stable supply of uniform products is great. The automatic supply of the fan-shaped pallets to the pallets and the automation of the pallet transportation become troublesome, and it becomes a simple work that does not require advanced technology again, and there is an effect that it is also useful for work improvement with simple operation.
