Abstract
The utility model discloses a special welding bolt mould, comprising a lower mould sleeve, a lower mould cushion and a product ejection pin. A lower mould core is arranged in the lower mould sleeve and the inner hole diameter of the lower mould core is matched with the size of the bolt head of the bolt. An advanced material-receiving movable guide sleeve can move up and down inside the lower mould sleeve and is nested inside the lower mould sleeve and the lower mould core. A through hole is arranged at the center of the advanced receiving-material movable guide sleeve and is matched with the size of the screw rod of the bolt. A spiral compression spring is arranged between the advanced receiving-material movable guide sleeve and the lower mould cushion. A buffering cushion is arranged on the lower mould cushion. The spiral compression spring is embedded into the buffering cushion. The structure used for producing the welding bolts is adopted by the mould, ensuring the qualified special welding bolt products to be produced by the mould after the materials are pre-machined and avoiding the mechanical processes so that the work efficiency is greatly improved; and the waste of the materials and the production cost are reduced.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of special welding bolt forming mould.
Background technology
Along with developing rapidly of China's industrial or agricultural, production technology and kind to all kinds of securing members require more and more higher, especially it is swift and violent that car industry development in several years is advanced by China, all kinds of securing members are had higher requirement, except standard fasteners, also need make all kinds of nonstandard products, to adapt to the needs of industry development; As certain car special welding bolt, its head is especially big, and bar portion is shorter, and the upsetting ratio reaches 10.61 times, and regulation steady-state deformation cold forging ratio must be less than 3 times in cold heading technique scientific principle opinion, otherwise the leading edge deformation difficulty is difficult to continuous production; Big and the short distortion difficulty of bar minister degree of this product head in addition moves at each station when being unfavorable for the product cold upset forming and causes producing continuously difficulty; Usually, the manufacturing of this product can only be earlier with reface screw thread after the cold-heading, but this technology shortcoming is its machining dimension control ratio difficulty when producing in enormous quantities, machined efficient is low, general 2-3 spare/minute, thereby the processing cost height, and serious through the machining waste of raw materials.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of special welding bolt mould that can produce nonstandard bolt.
For solving the problems of the technologies described above, special welding bolt mould of the present utility model comprises lower die-sleeve and following die-cushion, also comprise the product knock pin, in lower die-sleeve, be provided with lower mold core, the spiral shell area of bed coupling of lower mold core inner diameter hole and bolt, the socket activity guide pin bushing that connects material in advance in lower die-sleeve and lower mold core, the activity guide pin bushing that connects material in advance can move up and down in lower die-sleeve, its center has the through hole with the screw size of bolt coupling, also is provided with spiral compression spring between activity guide pin bushing and the following die-cushion connecting material in advance; Following die-cushion is provided with cushion pad, and spiral compression spring embeds in the cushion pad; Lower die-sleeve and lower mold core, become stationary fit between die-cushion, the cushion pad down, become movingly between connect material in advance activity guide pin bushing and lower die-sleeve, the lower mold core, the product knock pin is with following die-cushion, cushion pad, connect material to become movingly between the activity guide pin bushing in advance.
Because having adopted, special welding bolt mould of the present utility model is fit to the structure that nonstandard bolt is produced, make raw material after preprocessing, can produce qualified nonstandard bolt product by this mould, its per minute can reach 70 products, utilize this mould to need not to carry out machining processes, therefore improve work efficiency greatly, reduced raw-material waste, reduced production cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
