Abstract

The invention discloses an automatic forming machine for plastic wires, which comprises a main shaft driven by a motor, a wire inlet mechanism driven by the main shaft, a wire pre-profiling mechanism,a shaping and regulating mechanism and a forming and cutting mechanism. The wire inlet mechanism comprises a swing axle, a swing stem is arranged on the swing axle, the head of the swing stem is provided with a wire wrapping head, and wires are wound on the wire wrapping head; the wire pre-profiling mechanism comprises double turntables arranged on a stander, wrapping posts are arranged in the double turntables respectively, the wires are wound on the wrapping posts by the wire wrapping head, the double turntables are provided with circle diameter regulating devices, one side of the double turntables is provided with a guide plate, and the wound wires are led out from the guide plate; the shaping and regulating mechanism comprises an upper drive plate, a lower drive plate and double screws, wherein the upper drive plate and the lower drive plate are arranged on the stander, and a thread pitch regulating device is arranged between the double screws; and the wires which are shaped and regulated enter the forming and cutting mechanism which comprises a fixed die arranged between the double screws, a stamping head is arranged above the fixed die, fixture blocks are arranged under thefixed die at the two sides, the fixed die is matched with the stamping head and the fixture blocks, the stamping head and the fixture blocks are driven by the stamping device, and a tangent device isarranged at the end of the fixed die.

Description

technical field [0001] The invention relates to an automatic forming machine for plastic wires, which is suitable for producing various hooks, text coils, etc., especially double-coil automatic production equipment for loose-leaf binding of books, wall calendars, desk calendars and the like. Background technique [0002] In the original equipment for producing double coils, the wire is pressed into a rectangular tooth wire by a wire crimping machine, and then the product is stamped and formed by manual or semi-mechanized stamping equipment. It takes two workers to complete from forming to thread cutting, and the production efficiency of this type of machine is low. , the labor cost is high. Therefore, an automatic forming machine integrating crimping and stamping has been developed, such as the Chinese patent application number ZL200610115105.7. The teeth of the toothed chain on the sprocket are pressed into the space of the rectangular tooth line, and the positioning trans...
