Abstract
The utility model discloses a core print device of a tube drawing machine. The core print device comprises a core bar mounting seat; after a core bar rear section penetrates through the core bar mounting seat, the front end of the core bar rear section is connected with the rear end of a core bar front section through a thread and a nut; the front end of the core bar front section is connected with a core print through a quick joint; a spring and a spring limiting ring are arranged between the front end of the core bar rear section and the core bar mounting seat; a screw is arranged on the spring limiting ring; the core bar rear section is hexagonal; the shape of a hole in the core bar mounting seat adapts to that of the core bar rear section; a length adjusting block can be clamped into the rear end of the core bar rear section. The shape of the core bar is favorable for clamping, so that fastening is more effective and convenient, and the problem that the size of a product is not qualified due to loosening can be effectively solved; by virtue of the opening of the length adjusting block, the position of the core print can be adjusted more efficiently.
Description
Technical field
The utility model relates to a kind of chain type bench core head device, belongs to non-ferrous metal cold processing technique field.
Background technology
The core print position of chain type bench is mainly regulated by the amount of being threaded into that changes core bar at present, and forward and backward two sections core bars are all made by round steel.This structure mainly contains following two defects, and the one, the length adjustment piece is the closed hoop be through on core bar, when the length adjustment amount is larger, the plug back segment need be pulled down from the core bar mount pad, then be penetrated the length adjustment piece, efficiency is lower; The 2nd, when fastening forward and backward two sections core bars and core print, must use simultaneously two tool holdings, and be unfavorable for clamping because core bar is pole, can cause core print, core bar fastening not and cause that product size is defective.
Summary of the invention
The technical problem that the utility model solves is to provide under a kind of state not dismantling core bar carries out the core print position adjustments rapidly, guarantees simultaneously the bench core head device of effective tightness.
The technical solution of the utility model is:
A kind of bench core head device, comprise the core bar mount pad, after the core bar back segment passed the core bar mount pad, front end was connected with the rear end of core bar leading portion, the front end of core bar leading portion is connected with core print, the front end of core bar back segment is connected by screw thread and nut with the rear end of core bar leading portion, the front end of core bar leading portion is connected with core print by snap joint, between core bar back segment front end and core bar mount pad, be provided with spring and spring spacing ring, the spring spacing ring is provided with screw, the profile of core bar back segment is hexagon, the profile of the hole on the core bar mount pad and core bar back segment is suitable, the rear end of core bar back segment can snap in the length adjustment piece of an end opening.
The core bar leading portion is provided with hold-down nut near on rear end.
Beneficial effect: change the core bar back segment into hexagonal rod from pole, utilize the hole on the core bar mount pad to limit its rotation, hexagon weld nut is convenient to fastening on the core bar leading portion, when fastening, only need a monkey wrench, the core bar profile is beneficial to clamping, make fastening more effective and convenience, can effectively avoid the defective problem of product size caused because of loosening.From closed type, change the length adjustment piece into open type, can snap onto rapidly on the core bar back segment, remove the trouble of dismounting core bar from, because its bayonet socket is not circular arc, also do not worry its in use landing.Simultaneously, can adopt the length adjustment piece combination of different-thickness to realize the quick adjustment of core print position, reduce fine setting work, make the adjusting of core print position more efficient.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-core bar leading portion, 2-nut, 3-core bar back segment, 4-screw, 5-spring spacing ring, 6-spring, 7-core bar mount pad, 8-length adjustment piece, 9-snap joint, 10-core print.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of bench core head device, comprise core bar mount pad 7, core bar back segment 3 passes the rear front end of core bar mount pad 7 and is connected with the rear end of core bar leading portion 1, the front end of core bar leading portion 1 is connected with core print 10, the front end of core bar back segment 3 is connected by screw thread and nut 2 with the rear end of core bar leading portion 1, the front end of core bar leading portion 1 is connected with core print 10 by snap joint 9, between core bar back segment 3 front ends and core bar mount pad 7, be provided with spring 6 and spring spacing ring 5, spring spacing ring 5 is provided with screw 4, the profile of core bar back segment 3 is hexagon, the profile of the hole on core bar mount pad 7 and core bar back segment 3 is suitable, the rear end of core bar back segment 3 can snap in the length adjustment piece 8 of an end opening.
Core bar leading portion 1 is provided with hold-down nut near on rear end.
Spring spacing ring 5 is used for after holddown spring makes it keep certain elastic force, screw 4 to pass screwed hole on spring spacing ring 5 tightening, and its head of screw is pressed on the surface of core bar back segment 3, utilizes the position of stiction fixing spring spacing ring 5.
Because there is elastic force in spring 6, under nature, the front end of core bar back segment 3 is from keeping the longest state that stretches out core bar mount pad 7, while needing to shorten, can be by core bar back segment 3 firmly toward pusher, snap in its back-end simultaneously length adjustment piece 8, the length adjustment scope changes with thickness and the quantity of the length adjustment piece 8 of the overall length of core bar back segment 3 and insertion.When length adjustment is larger, need readjust the position of spring spacing ring 5 to adjust the elastic force of spring 6.
