Abstract
The utility model discloses a bearing pin which comprises a thread upper end and a cylinder lower end, wherein the thread upper end and the cylinder lower end are separated through a shaft shoulder, a transition fillet is arranged on the connection portion of the thread upper end and the shaft shoulder, and the thread diameter of the thread upper end is 14mm. The bearing pin is simple in structure. The transition fillet is arranged on the connection portion of the thread upper end and the shaft shoulder, and the thread diameter of the thread upper end is 14mm, thus strength of extension is promoted, the bearing pin can not break for several months, averagely, 60 hours of maintenance time for equipment is saved per month, and in other words, averagely, output of six days is added per month. The running rate of the equipment is greatly promoted, and production efficiency is improved.
Description
Technical field
The utility model relates to the bearing pin technical field, relates in particular to a kind of opening sealing forming machine and pulls out bearing pin on the straight mould.
Background technique
