Description
Technical field
The utility model is specifically related to a kind of static contact of high-voltage switch extrusion die.
Background technology
At present, a lot of manufacturers adopt the mode of centrifugal casting to produce static contact.This explained hereafter cost is lower, but product easily produces shrinkage cavity, loosens, and density of material is lower, and then causes part conductance and low strength.The high-voltage switch contact that centrifugal casting technique is produced, in last manufacturing procedure, in the process of milling lobe, easy fracture comes off, and finished product is while being installed on high-voltage switch gear long-term use, under the strain effect of Self-help contact terminal, easy fracture comes off, and causes a serious accident.Therefore, the static contact quality that centrifugal casting is produced is unstable, and poor-performing, says the performance requirement that can not meet high-voltage switch contact and cylinder on stricti jurise.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, and a kind of static contact of high-voltage switch extrusion die is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of static contact of high-voltage switch extrusion die, comprise lower bolster, push rod, guide pillar, backward extrusion spring, guide pin bushing, cope match-plate pattern, shedding mechanism, pin, convex mould pad, screw, punch retainer, punch, product, die, gasket ring, die shrink ring, ejector, die holder and die backing plate, lower bolster mould below, push rod connects respectively lower bolster and die backing plate, guide pillar connects respectively lower bolster and cope match-plate pattern, backward extrusion spring connects shedding mechanism, guide pin bushing connects guide pillar, cope match-plate pattern connects convex mould pad, shedding mechanism connects punch, pin connects cope match-plate pattern, convex mould pad connects punch, screw connects respectively cope match-plate pattern and convex mould pad, punch retainer connects convex mould pad, punch connects respectively convex mould pad and ejector, die connects die shrink ring, gasket ring connects punch, die shrink ring connects die holder, ejector connects die backing plate, die backing plate connects lower bolster.
The utility model also has some technical characterictics like this:
Described shedding mechanism comprises unloading bolt and stripper, and unloading bolt connects backward extrusion spring, and stripper connects unloading bolt.
Described ejector can be guaranteed can take off smoothly when part is stayed die.
Described a kind of static contact of high-voltage switch extrusion die will be shaped through twice extrusion process.
The utlity model has following useful effect:
The utility model is reasonable in design, easy to use, and cost is low, and stock utilization is high, and production efficiency is high, has good economic benefit.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein, 1, lower bolster, 2, push rod, 3, guide pillar, 4, backward extrusion spring, 5, guide pin bushing, 6, cope match-plate pattern, 7, unloading bolt, 8, stripper, 9, pin, 10, convex mould pad, 11, screw, 12, punch retainer, 13, punch, 14, product, 15, die, 16, gasket ring, 17, die shrink ring, 18, ejector, 19, die holder, 20, die backing plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
