Abstract
The invention relates to a die for punching a rotary buckle. The die consists of an oil cylinder (1), a bracket (2), an upper die frame (3), an upper die (4), a lower die (5) and a lower die frame (6), wherein the upper die (4) and the lower die (5) are respectively fixed on the bracket (2) through the upper die frame (3) and the lower die frame (6). A joint II (8) is placed in a cavity of the lower die (5), and a joint I (9) is then placed on the joint II (8). The die is characterized in that the upper die (4) is assembled with the lower die (5) through the oil cylinder (1) so as to punch and form the joint II (8) and the joint I (9) in a butt joint manner. The die provided by the invention is simple in processing process, fast in processing speed and high in yield, so that the tensile strength of the product processed is greater than 400 kg. The die can be quickly changed, and satisfies different product processing demands.
Description
Technical field
The present invention relates to a kind of mould for the turn buckle of connection cord on the marine surfboard.
Background technology
The surfing rope that uses in the surfing is the connection cord that connects surfboard and human body, plays the important function that ensures sportsman's personal safety, need to adopt stainless steel and the processing of high-quality copper material and connect handware, the long-term corrosion of energy sea water resistance.It all is to adopt the integral type design that major part before connects handware, can't rotate, and uses wrapping phenomena occurs often.After change to the rotatable junction button in two, the winding problem before having solved.But in process of production because technical parameter and process issues, the junction button pulling force of producing is unstable, the phenomenon that is lower than international standard 400KG is often arranged, cause the phenomenon that rope and surfboard come off often occurs in the surfing process, thereby cause the security incident of the person and property.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of mould of punching press turn buckle, be to use the method for punching press with the one-shot forming of male and female junction button, can be effectively antiwind.
In order to achieve the above object, the present invention takes following technical proposal: a kind of mould of punching press turn buckle, formed by oil cylinder, support, top mold frame, upper die and lower die and lower mold holder, patrix is separately fixed on the support by lower mold holder by top mold frame, counterdie, the joint II is placed in the lower mode cavity, the joint I is put on the joint II again, be it is characterized in that: described patrix is realized joint II and the punching press of joint I docking moulding by oil cylinder and counterdie matched moulds.
Have the counterdie aperture F with tapering on the described counterdie, the below in counterdie aperture is provided with a tapering, and its tapering is consistent with the external conicity of joint II, and lower nib F is less than the cylindrical E of joint II, the extrusion of joint II.
Have two inside grooves on the described joint II, the diameter of groove 8-1 is greater than the diameter of the outer circular hole 8-2 of joint II, the diameter of outer circular hole 8-2 less than the cylindrical 9-2 diameter of joint I 9, makes joint I 9, joint II 8 can rotate freely and can't pull out greater than the diameter of joint I groove 9-1; The width of groove 9-1 is greater than the distance of groove 8-1 to end face.
The present invention, processing technology is simple, is easy to manufacturing, product hot strength height, and process velocity is fast, saving of work and time; Yield rate is high.The product tensile strength that processes is greater than 400kg.
