Abstract

A method for manufacturing a perforated and corrugated blade-type drain pipe for filtering and the structure of a forming mold are provided to increase productivity by executing molding and manufacturing processes with an automated system and to improve economical efficiency by reducing manpower and the manufacturing time. The method for manufacturing a perforated and corrugated blade-type drain pipe for filtering comprises the steps of: installing mold bodies having recessed perforated and corrugated semicircular ring cylinders of perforated and corrugated ring structures(4,4a), at both sides of a driver unit of a synthetic resin forming mold with facing each other and successively engaging the mold bodies at regular intervals; molding an initial product by molding the synthetic resin material on the recessed surfaces formed inside the mold bodies by blowing pneumatic pressure at the same time in injecting the synthetic resin material when both mold bodies are engaged with each other; making a half-finished product by forming corrugated blades(8,8a,8',8a') at both sides by pressing the initial product with a press unit and welding fusion parts(6) by ultrasonic waves; finishing the perforated and corrugated blade-type drain pipe by boring drain holes(3a) by cutting hole forming protruded parts projected at the periphery of the perforated and corrugated ring; and covering the peripheral part of the drain pipe with a filter and then winding the drain pipe around a drum.

The present invention relates to a manufacturing method and a structure of the manufacturing mold of the filtration hole drainage pipe for filtration used to promote the dehydration of the soft ground containing a lot of water (water), more specifically, the indentation hole wrinkles on the inner surface of the body The molds arranged on both sides of the semi-cylindrical cylinder structure are expanded to the proper angle to form a corrugated wing, and are arranged so as to be opposite to both sides by the molding mold. When a plurality of molds arranged opposite to each other while being driven by the configured driving device are sequentially aligned, the synthetic liquid support material (stock solution) is injected and the appropriate air pressure is blown in to form the structure formed on the inner surfaces of both molds. Synthetic water support solution is appropriate for the structure of the urinary hole wrinkle semi-cylindrical cylinder and the structure of the corrugated corrugated wing As the deposit is molded into the ends of both sides wave pleated wing of the Annex is manufactured by forming the initial product.

In this way, it is proposed to complete the production of the present invention by the step of forming the initial product manufactured by the bonding step and the hole drainage, filter covering step and winding the drum.

In forming a pleated drainage pipe for filtration having a large dehydration conversion area as disclosed in the applicant's patent No. 10-0340236 (published date: 2002.06.10), the perforated corrugated pipe and the corrugated corrugated wing are separately molded and manufactured. Since the corrugated wing was attached to both sides by separate manual work, it was inefficient workability and costly to manufacture, and there was a defect that the productivity of the product was largely insufficient according to the demand.

An object of the present invention is to automate the production of the product step by step in order to solve the drawbacks of the prior art to improve the productivity by the ease of operation to increase the added value.

The present invention will be described in detail with reference to the accompanying drawings.

Large corrugated ring 4 and small corrugated ring 4a having a large inner diameter of the mold body 1 having the driving gear 2 formed on one side, and having several hole-forming protrusions 3 protruded in the circumference thereof. Wave-shaped corrugated wings 8 and 8a are formed in a concave shape by spreading from both ends of the concave hole cylindrical semicylindrical cylinder 5 forming a concave shape, thereby forming a high valley 7 and a low valley 7a from the fusion portion 6. do.
At this time, the angle of opening from both ends of the urinary hole crease semi-cylinder cylinder 5 is preferably an angle of 115 ° to 135 ° from both ends, with the central portion of the urine hole crease semi-cylindrical cylinder 5 as an effective point.

Each mold body (1) (1a) is installed by driving a plurality of mold bodies (1) (1a) formed in this way to be installed so as to be opposed to both sides of the drive unit in the synthetic resin molding frame (not shown) separately configured By the rotation, and coincides sequentially as shown in Figs.

As such, when the both sides of the mold bodies 1 and 1a coincide with each other, the synthetic support material (stock solution) is injected and the appropriate air pressure is blown into the indentation hole pores of the structure formed on the inner surfaces of the mold bodies 1 and 1a. Synthetic resin solution is deposited on the semi-cylindrical cylinders (5) (5a) and corrugated wing (8) (8a) (8 ') (8a') at an appropriate thickness to be molded, and the corrugated wing (8) (8a) (8) is formed on both sides. An end portion of the '8a' is sealed and molded into an initial product (a) as shown in FIG.

The initial product (a) molded in this way is formed by the joining device part (not shown) which is formed in the same line as the above-mentioned molding frame, so that the corrugated wings 8, 8a, 8 'and 8a' of both sides are formed. By coincidence and ultrasonic welding of the welded portion 6, the corrugated wing wings 8, 8a, 8 'and 8a' on both sides are integrally bonded to the intermediate product (b) as shown in FIG. Each of the hole forming protrusions 3 is cut by the cutting step, which is the next step, and is completed as the actual product (C) which becomes a hole-wrinkled drainage pipe formed by opening the drain hole 3a.

In this way, the hole-wrinkled drainage pipe completed with the actual product (C) is cooled and rotated at 90 ° to be wound around the drum while covering the filter (nonwoven fabric) 9, thereby completing the molding production of the present invention.

 The present invention as described above is conventionally developed a mold body that can be molded simultaneously with the hole tube and the corrugated wing integrally work to rely on the manual operation of attaching separate corrugated wing to both sides of the perforated tube can be molded and manufactured By completing the automation system, it is possible to improve the economic efficiency by reducing productivity and time by improving productivity through efficient workability and meeting the demand.
