Description
Technical field
The utility model relates to a kind of pretension and enlarging apparatus of steel pipe cutting ferrule.
Background technology
Conventional steel chip sleeve premounting is divided into two processes, and first step is pretension, and second step is enlarging.Pretension process need manually packs corresponding coupling into fixture to be fixed, then steel pipe, cutting ferrule and nut are put into joint steel pipe groove, follows manual fastening nut and makes cutting sleeve pretightening, finally unscrews nut taking-up steel pipe and completes pretension.Enlarging process need packs fixture into the steel pipe pulling tight in advance to be fixed, and the enlarging specific purpose tool of approximately 15 ° of cone angles is put into steel pipe opening, and iron hammer knocks enlarging specific purpose tool, makes steel pipe expand enlarging.Two processes all waste time and energy, and affect manufacturing schedule; And cutting sleeve pretightening degree disunity, the size of the power that enlarging is knocked is disunity also, and too tight or too loose chip sleeve premounting all can affect the sealing of fluid pressure line, thereby affects the quality of final products.
Summary of the invention
Problem to be solved in the utility model is to overcome the problems referred to above that existing artificial installation exists and steel pipe cutting ferrule pre-tightening apparatus and steel pipe cutting ferrule expanding device thereof are provided, to improve production efficiency and product quality.
The utility model solves the problems of the technologies described above adopted technical scheme:
Steel pipe cutting ferrule pre-tightening apparatus, comprise cutting sleeve pretightening clamp, cutting sleeve pretightening oil cylinder, cutting sleeve pretightening die head, the fixedly steel tube clamping groove of steel pipe cutting ferrule is set on cutting sleeve pretightening clamp, cutting sleeve pretightening die head is fixed on the piston rod of cutting sleeve pretightening oil cylinder, and cutting sleeve pretightening die head enters and clamps steel pipe cutting ferrule and pretension steel pipe cutting ferrule and leave the steel pipe cutting ferrule after pretension under the driving of cutting sleeve pretightening oil cylinder.
Steel pipe cutting ferrule expanding device, comprise cutting ferrule enlarging clamping device, cutting ferrule enlarging oil cylinder, steel tube flaring die head, cutting ferrule enlarging clamping device comprises cutting ferrule enlarging clamping cylinder, grip block, clamping plate, clamping plate is fixed on the piston rod of cutting ferrule enlarging clamping cylinder, under the driving of cutting ferrule enlarging clamping cylinder, clamping plate stretches and in cutting ferrule enlarging clamping slot at clamping plate, clamps or unclamp steel pipe, over against cutting ferrule enlarging clamping slot, cutting ferrule enlarging oil cylinder is set, fixing steel tube flaring die head on the piston rod of cutting ferrule enlarging oil cylinder, under the driving of cutting ferrule enlarging oil cylinder, steel tube flaring die head enters steel pipe head and makes the enlarging of steel pipe head and leave the steel pipe head after enlarging because stretching.
Compare with existing artificial installation, can save pre-ETL estimated time of loading, reduce labor strength, Improving The Quality of Products.Whole installation cost is low, easy to operate.
