Abstract

The present invention is to provide a method for manufacturing hose clamp. A thin plate is forwarded a fixed distance in a mold set for every stamping stroke performed, to make the thin plate being sequentially stamped to form a spreading-shape casing with guiding holes, limiting slot, boundary slot and ribs, thus forming a developed shell member. Then, through further stamping operations by the same mold set, the extending parts of the two sides of spreading-shape casing are gradually deformed into a downward and inward curved configuration, and a suitable distance is formed between the two extending parts, so as to form a wrapping-shape casing blank. A stripe binding belt having receiving holes is then inserted into the wrapping-shape casing blank. By means of time difference effect of stamping operation performed by the aforementioned mould set, the mould set tightly clamps two sides of the extending parts of the casing first, immediately compresses the extending parts and the binding belt, and then cutting off the casing and the ribs.

Further, its production is greatly restricted. V. The invention description (4) process is more complicated and inconvenient, and another problem. A 3. As mentioned in item 2, it requires more manpower to perform secondary or secondary processing, so that its overall cost cannot be reduced, and it will also reduce its market competitiveness. . 》 Because of this, the creator is actively developing research, and in order to improve the lack of the conventional pipe clamp manufacturing, the creator has developed and designed this book after years of hard research and experiments based on years of experience in manufacturing such products. The creation of the pipe clamp manufacturing method will benefit all consumers and manufacturers. The main purpose of the manufacturing method of the pipe clamp of this creation is to provide a method in which the thin plate body is moved and fixed within each stroke of the die set. Guided holes, limit grooves, boundary grooves, ribs, etc. form the unfolded shell, and then continue to punch up and down several times through the same mold group, so that the protruding portions on both sides of the unfolded shell will gradually downward. The inner shell is bent into a cladding-shaped shell shape, and then a straight strip with a receiving hole at the end is inserted into the cladding-shaped shell shape. Finally, by the last punching of the above mold group, The time difference causes the mold group to clamp the two sides of the convex portion of the shell first, and then press the convex portion and the strap to deform the combination, and immediately cut the shell and ribs at the same instant; so, Not only can the strap and the shell < body be assembled together with only one pair of molds to reduce the cost of the mold, at the same time, the thin plate body can also be punched through the same mold group several times, and Straighten the straps and shell Combined and assembled into one body, and can avoid the assembly of secondary processing, so as to make its manufacturing process more simplified and faster, which can increase its output and market
