Abstract
The invention discloses a spring core rod. The spring core rod comprises a main core rod, an embedded type core rod, a spring, a core rod fixing screw and a spring clamp, wherein the embedded type core rod is arranged on a working platform surface, the spring is arranged at the top part of the embedded type core rod, the main core rod is sleeved on the spring through a bottom groove, the core rod fixing screw is arranged on the working platform surface by penetrating through a center hole of the main core rod, two arms of the spring clamp penetrate through the bottom part of the main core rod, the bottom ends of the two arms of the spring clamp are provided with outward clamping hooks, the clamping hooks can be clamped in barbs which are arranged at the inner side of the embedded type core rod, and the main core rod drives the spring clamp to move vertically. The spring core rod disclosed by the invention has the advantages that when the spring core rod is in work, the main core rod moves downwards as the main core rod is subjected to a friction force, thus the bottom part of a forming material which is close to the position of the main core rod is subjected to an upward extruding force, and the forming density at the position is consistent with that on an upper pressing surface; and the spring clamp is driven to downwards compress the spring when the main core rod moves downwards, a compression device is locked by clamping the clamping hooks in the barbs, thus the condition that a grinding wheel is damaged as the main core rod is erected by the spring after the pressure at the upper part of the forming material is removed is prevented.
Description
Technical field
The present invention relates to a kind of plug, be specifically related to the spring plug that uses in a kind of large thickness abrasive wheel forming pressing process with a high standard.
Background technology
In large thickness abrasive wheel forming process with a high standard, because molding mass in pressing process and the huge friction between the mould, plug, causes by the upper lower density of forming grinding wheel inconsistent.Traditional solution is at parallels of die sleeve underlay, takes out parallels when being added to certain pressure, and the outer radius density of grinding wheel bottom and upper pressure surface are consistent, but the method still can't improve the compact density at plug place, bottom.There are two problems in produced like this emery wheel: (1), emery wheel density are inconsistent, cause the emery wheel soft or hard inconsistent, affect the serviceability of emery wheel; (2), emery wheel in rotary course, greatly power concentrates on the emery wheel inner radius, emery wheel inner radius density is low, can reduce emery wheel tensile strength.
Summary of the invention
Goal of the invention: goal of the invention of the present invention provides a kind of spring plug, solves the compact density problem at large thickness abrasive wheel forming material with a high standard plug place, bottom in pressing process.
Technical scheme: spring plug of the present invention, comprise the main body plug, embedded plug, spring, plug hold-down screw and spring chuck, described embedded plug is installed on the work top, described spring fitting is at the top of embedded plug, described main body plug is enclosed within on the spring by bottom groove, the centre bore that described plug hold-down screw passes the main body plug is installed on the work top, two arms of described spring chuck pass the bottom of main body plug and are provided with the snap fit that turns up in the bottom, described snap fit can snap in the inboard hangnail that arranges of embedded plug, and the main body plug drives spring chuck and moves up and down.In abrasive wheel forming material pressing process, the main body plug is subjected to frictional force to drive spring chuck downwards and Compress Spring, constantly snaps in the inboard hangnail internal lock that arranges of embedded plug in the process that is hooked in down of spring chuck and decides compression position; After compacting finishes, give inside pressure of spring chuck two arms, make snap fit unclamp hangnail, the main body plug is got back to initial position by the elastic band of the spring spring dop of moving.
Beneficial effect: the present invention compares with existing abrasive wheel forming material compact technique, its distinguishing feature is to be subject to upper pressure to compress that the main body plug can be because be subject to frictional force and then downwards when downward in abrasive wheel forming material pressing process, make the molding mass bottom near main body plug place be subject to a crowded power that makes progress, compact density and the upper pressure surface at this place are consistent, and because the main body plug drives spring chuck when downward together and Compress Spring downwards, the hangnail that snap fit by spring chuck snaps in embedded plug locks compression position, prevent that after the molding mass upper pressure is laid down spring jack-up main core rod damages emery wheel.
Description of drawings
Fig. 1 is the longitudinal sectional view of the spring plug of the embodiment of the invention when not working;
Fig. 2 is the longitudinal sectional view in spring plug when work of the embodiment of the invention.
The specific embodiment
The present invention is described further below in conjunction with specific embodiment.
Spring plug of the present invention, comprise main body plug 1, embedded plug 2, spring 3, plug hold-down screw 4 and spring chuck 5, embedded plug 2 is installed on the work top 7, spring 3 is installed in the top of embedded plug 2, main body plug 1 is enclosed within on the spring 3 by bottom groove, the centre bore 11 that plug hold-down screw 4 passes main body plug 1 is installed on the work top 7, two arms of spring chuck 5 pass the bottom of main body plug 1 and are provided with the snap fit 51 that turns up in the bottom, snap fit 51 can snap in the embedded plug 2 inboard hangnails 21 that arrange, and main body plug 1 drives spring chuck 5 and moves up and down.
The middle that specifically is installed in mould of spring plug of the present invention.The compacting of abrasive wheel forming material is exerted pressure at twice and is finished:
For the first time, 2/3 of the usefulness gross pressure pressure pressing, the abrasive wheel forming material is subject to upper pressure to lower compression, main body plug 1 is subject to frictional force and drives spring chuck 5 and then and Compress Spring 3 downwards, and the snap fit 51 of spring chuck 5 constantly snaps in embedded plug 2 inboard hangnail 21 internal locks that arrange and decides compression position in process down.Compacting is finished, and unclamps pressure, removes the cushion block 6 under the die sleeve 8.
Exert pressure with gross pressure for the second time,, the abrasive wheel forming material is subject to upper pressure to be continued to lower compression, main body plug 1 is subject to frictional force and continue drives spring chuck 5 and then and continue Compress Spring 3 downwards, and the snap fit 51 of spring chuck 5 continues down to snap in hangnail 21 internal locks of embedded plug 2 and decides compression position.
Because main body plug 1 can be because being subject to frictional force and then downwards in whole pressing process, make the molding mass bottom near main body plug 1 place be subject to a crowded power that makes progress, compact density and the upper pressure surface at this place are consistent, and because main body plug 1 drives spring chuck 5 downwards the time together and Compress Spring 3 downwards, the hangnail 21 that snap fit 51 by spring chuck 5 snaps in embedded plug 2 locks compression position, prevent that after the molding mass upper pressure is unclamped or laid down spring 3 jack-up main body plugs 1 destroy emery wheel.
After whole compacting finishes to take out emery wheel, only need the inside pressure of two arms to spring chuck 5, just can make snap fit 51 unclamp the hangnail 21 of embedded plug 2, main body plug 1 is got back to initial position by the elastic band of the spring 3 spring dop 5 of moving.
