Description

A kind of Spring screws
Technical field
The utility model relates to a kind of Spring screws, the Spring screws that uses when relating in particular to a kind of pile tube punching block matched moulds.
Background technology
Existing Spring screws comprises screw rod, the spring adapter sleeve, spring, fixed operating sleeve, nut and nut sleeve, wherein screw rod comprises spiro rod cap, the linkage section and the screwed section of being threaded that do not have screw thread, linkage section is positioned at spiro rod cap and is threaded intersegmental, the linkage section and the intersegmental shaft shoulder that is provided with that is threaded, socket spring adapter sleeve on the linkage section of screw rod, spring and fixed operating sleeve, the spring adapter sleeve is close to spiro rod cap, be connected spring between spring adapter sleeve and fixedly connected inner room adapter sleeve, nut is threaded on the screw flight linkage section, nut overcoat connected nut cover, fixed operating sleeve is bolted to connection on the patrix of punching block, and nut sleeve is welded on the counterdie of punching block.When matched moulds, need the professional that screw is gone to collude on the patrix from counterdie upset patrix or with pin and tighten with the wind big gun again, inconvenience is installed, inefficiency, and have potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of Spring screws easy and simple to handle.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of Spring screws comprises screw rod, compression spring pad, spring, fixed muffle, following stage clip pad, base and hold-down nut.Screw rod comprises spiro rod cap, does not have the linkage section and the screwed section of being threaded of screw thread, linkage section be positioned at spiro rod cap and be threaded intersegmental, the linkage section and the intersegmental shaft shoulder that is provided with that is threaded.Socket compression spring pad, spring, fixed muffle, following stage clip pad and base on the linkage section of described screw rod, the described section of being threaded is connected and fixed nut.Socket fixed muffle between the linkage section and the section of being threaded, fixed muffle is socketed with down stage clip pad and base.The compression spring pad is close to spiro rod cap, and following stage clip pad is fixed on the base by four screws, and spring places between compression spring pad and the following stage clip pad, spring one end socket compression spring pad, other end socket fixed muffle.
As preferably, described Spring screws diameter is between T20-T27.This preferred version, the serviceability height of spring helps prolonging service life of Spring screws.
As preferably, described screw flight linkage section adopts T type screw thread.This preferred version makes hold-down nut closely cooperate with the section of being threaded, and makes that the punching block matched moulds is fastening.
As preferably, described hold-down nut and screw rod adopt the 40Cr material.This preferred version, hold-down nut and screw rod rigidity height help improving the Spring screws serviceability.
As preferably, described except that hold-down nut and screw rod the Spring screws part adopt 45# steel material.This preferred version, production cost is low.
In sum, the beneficial effect that the utility model brings is: when this spring spiral shell uses, only need to use the movable hold-down nut of spanner promptly to install, dismantle, change conveniently, increase work efficiency, reduce production costs.
