The present invention relates to a method for manufacturing a coated or plated plastic FLAT HEALD used for high performance looms such as water jet, air jet, and rapier.

To date, generally, plate heald is made of stainless steel.

The plate-shaped heald of stainless steel is adhered to the heald after it is released from the yarn to a fine floating state as the sizing flotation (grass debris) formed in the yarn is in contact with the heald during long-time high-speed weaving.

The sticking phenomenon of the sized floating material causes the weight of the heald to gradually increase as time passes, and thus the power consumption required to operate the heald at high speed increases.

In addition, the operation speed of the heald decreases, and the failure rate of the weaving fabric increases the failure rate of the weaving fabric, or in the worst case, a lot of the healds in the heald frame are entangled and the loom operation is stopped.

Therefore, in recent years, synthetic resin heald has been developed in order to overcome this problem and to reduce the weight of looms and lower the cost of the accessory (heald).

Conventionally, for example, in the case of Korean Utility Model Registration 20-268659, it is described that the alumina nylon resin is compressed to suit the purpose, but there are already various kinds of various kinds of synthetic resin thin films such as PVC, PP, including alumina nylon resin (A1₂O₃Nylon) The molding method is a general molding method for forming a metal plate and does not provide a molding method considering the characteristics of the synthetic resin thin plate.

In addition, although the Korean Patent Laid-Open Publication No. 2003-89121 proposes a general molding method of forming a metal plate by mounting a mold on a press, the characteristics of the synthetic resin thin plate (0.3 mm-0.5 mm) are not considered at all, and thus, it is applied to actual product production. I can't do it.

In order to solve the problems of press molding synthetic resin thin plate heald production, injection molding synthetic resin heald is produced, but ultra-thin plate (0.3mm-0.5mm) is impossible, and the wear strength and durability are greatly reduced due to the decrease in tensile strength, and the production (manufacturing) cost is high. It is a problem.

An object of the present invention is to roll up (coil) various synthetic resin thin plates (alumina nylon, PVC, PP, and other various synthetic resin films) that are produced and distributed in large quantities on the market, and form a heald in a punching press, It is to provide a coating or plated synthetic resin plate heald having a characteristic that can be banded after the bending, and then coated after instant polishing or plating after polishing.

Another object of the present invention is to improve the durability and reliability of the product, and to provide a synthetic resin plate heald for a loom that has been given a minimum production cost and optimum functionality.

The object of the present invention is that the narrow part between the heald and the heald and the upper and lower ears and the scrap of the central eyelet are simultaneously cut in the punch mold 11. A punching press step 10 of punching in the state in which only the upper and lower ends of the heald are connected to the synthetic resin sheet fabric 1;

In the punching press step 10, a synthetic resin sheet fabric 1 having a width capable of satisfying the length of heald to be completed is supplied in a wound state.
When shaping the narrow part, the upper and lower ears, and the narrow part of the central eyelet, the upper and lower ends of the heald are punched while being connected to the sheet fabric 1. and,
After the synthetic resin sheet fabric 1 in the state where the upper and lower ends of the heald are connected to the rewinding roller 21, the rewinding roller 21 undergoes a rewinding process 20, and then, by the bending die 31 of the bending press process 30. The healds connected to the upper and lower ends are achieved by cutting from the synthetic resin sheet 1 at the same time as the uneven banding.

Therefore, it is possible to improve the durability and reliability of the heald, and to give economic benefits with a minimum production cost.

The punching press step 10 is a step of punching the approximate shape of the desired heald by supplying the synthetic resin sheet fabric 1 to the punch mold 11.

Synthetic resin sheet (1) is wound to bobbin with a width that can satisfy the length of heald to be finished, and the scrap between upper and lower healds, upper and lower ear and central eye ( The scrap of the eyelet is simultaneously cut out of the punch mold 11.

At this time, the heald is punched in the state in which only the upper and lower ends are connected to the synthetic resin sheet fabric 1.

Synthetic resin sheet (1) is made of alumina nylon, PVC, PP, and other synthetic resin film is wound in the bobbin in a relatively thin plate state of the extrusion method thickness of approximately 0.3mm-0.5mm, as in the present invention continuous Winding is for mass production.

The metal mold | die mounted in this punching press process 10 is a progressive mold (Progresive die), and is punched in the shape of the desired heald.

At this time, the heald is arranged so that the length is arranged in a direction perpendicular to the punch mold 11 and the bending mold 31, as shown in Figure 3, the reason is the rolled (coiled) synthetic resin sheet 1 Due to the phenomenon of being released in a very thin state between 0.3mm-0.5mm and being passed through the progressive style punch mold 11 to be formed into a heald (2), it is to be restored to the mold by the property of being wound in a coil shape for a long time. When the mold is arranged and molded so that the length of the heald is in the direction in which the original fabric 1 is released, the molded heald 2 may be deformed into a half-moon shape after molding.

Therefore, if the heald (2) deformed in the form of a half moon is impossible to normal operation in the other process and the final product is also a half moon form, which is not only inconvenient to store and move, but also causes considerable difficulties when mounted on the loom.

Therefore, in the punching press process 10 as shown in the drawing, the narrower and the upper and lower ears and the central part of the slab between the healds 2 are arranged so as to be arranged in the orthogonal direction of release. After the scraps of the eyelet are cut at the same time, only the both ends of the heald 2 are rewinded to the rewinding roller 21 continuously in the state of being attached to the synthetic resin sheet 1.

The rewinding step 20 is supplied to the next bending press step 30 in the state where both ends of the light receiver 2 are connected to each other while being wound by the rewinding roller 21 as described above.

The bending press process 30 is a process of cutting and separating the unevenness and the twist portion necessary for the finished heald from the synthetic resin sheet 1 completely.

That is, when the synthetic resin sheet fabric 1 is supplied from the rewinding roller 21 of the rewinding process 20, the central part eyelet of the heald by the bending die 31 is formed with the heald and the axial angle. ) It is banded to be 30˚ ~ 45˚.

The upper and lower parts of the upper and lower ears are symmetrically bent and shaped by the bending mold 31, and the light-receiving member 2 connected to the synthetic resin sheet fabric 1 at the upper and lower ends is separated and cut.

Therefore, it is possible to continuously produce a large amount of resin acceptor in a short time.

On the other hand, the synthetic resin heald after the process is difficult to use directly on the loom due to the sharp cutting (cutting) surface and the unfavorable bending surface generated during the punching process and the bending molding process.

Therefore, in the present invention, to solve this problem, by removing the burrs (BUT) of the cutting surface and the bending surface by the polishing means is possible to use a high-speed loom in the coating plating process 50, the plating and coating is possible synthetic resin plate heald ( Plastic FLAT HEALD) is to be produced.

The polishing process 40 is a process of polishing and removing burrs on a cutting surface generated during cutting while the heald separated from the synthetic resin sheet fabric 1 in the bending press process 30 passes through the polishing means.

Here, the polishing means is to remove the burrs on the cutting surface by passing between the grinding charcoal is rotated in the state maintaining the gap in consideration of the thickness of the heald, the correct gap up and down, or the polishing liquid having a synthetic resin dissolving ability Note that a method of instantaneously removing burrs by instantaneous passage at high speeds can be used.

In the polishing process 40, a coating plating process 50 is performed to coat the surface coating agent and the plating liquid on the surface of the heald removed from the burr.

The plating material used in the coating plating process 50 may be formed by electrolytic plating or hard plating of various materials such as nickel, chromium, copper, etc. after polishing depending on the use of the seed material.

Then, heald can be obtained by spraying the washing liquid and drying the clean surface.

According to the configuration of the present invention as described above, it is excellent in heat resistance, water resistance, corrosion resistance, light weight, abrasion resistance, flexibility, high elasticity, non-adhesiveness of the sizing float, the sintered floating material generated when the high-speed high-end loom is operated for a long time Since no sticking occurs to the heald, the power consumption is low and the fabric defect rate is greatly reduced.

In addition, it is possible to prevent the operation stop phenomenon due to the entanglement of the heald, and the price of the heald is also very useful invention, such as having a very inexpensive feature.
