Abstract

The utility model discloses a guiding and range limiting assembly. The guiding and range limiting assembly is characterized by comprising a guide column, a guide sleeve, a polyurethane gasket, a steel gasket and a range limiting plate, wherein the polyurethane gasket and the steel gasket are sleeved on the guide column; the guide sleeve is mounted in a guide sleeve mounting hole of a mould body; the range limiting plate is aligned to a range limiting groove part of the guide column and is fixed on the mould body to press the guide sleeve; the guide column sleeved with the polyurethane gasket and the steel gasket passes through the guide sleeve mounted in the guide sleeve mounting hole of the mould body; a pressing plate is fixedly mounted at the lower end of the guide column through screws. The guiding and range limiting assembly has the advantages as follows: a guide part and a range limiting part are combined into an assembly, dual effects of guiding and range limiting are achieved, and the difficult problem that the guide part cannot be mounted as the pressing plate of a mould is not as thick as a cast iron piece when the pressing plate adopts a steel plate is solved.

Description

The limit journey assembly of tape guide

(1) technical field:

The utility model is for the design production application of automobile panel blanking or postorder mould, for the design of blanking order and postorder mould provides a kind of structure of clustered operation.

(2) technical background:

It is complicated that current automobile panel production faces product, the trend of mould summary.Some operations are under original mould manufacturing theory, and working it out may be heavy continuity, so not only wastes material, has improved cost, and are not suitable for the development of mould.For example, the rise and fall binder parts of little trimming die of the blanking die that some are small-sized or profile, just can break away from the past the cylinder iron manufacture custom of material, and use steel plate instead, replaced.Because it is so not thick to use the material pressing core of steel plate can not look like ironcasting, so the laying method of limit journey and guiding parts is most important.This utility model is exactly in the situation that alleviating mold integral weight, solves the Placement Problems of limit journey and guiding parts with the most succinct structure.

(3) utility model content:

The utility model object is to provide a kind of limit journey assembly of tape guide, and it can overcome the problem that produces limit journey and the bad deployment of guiding parts while using steel plate material to do material pressing device, and problem provides a kind of structure that can firmly lead and limit journey for this reason.

The technical solution of the utility model: a kind of limit journey assembly of tape guide, is characterized in that it comprises guide pillar, guide pin bushing, polyurethane packing ring, steel washer and stroke limit plate; Described polyurethane packing ring and steel washer are enclosed within on guide pillar; Described guide pin bushing is arranged in the guide pin bushing installing hole of die ontology; The limit journey groove location of described stroke limit plate alignment guide post is also fixed on and on die ontology, pushes down guide pin bushing; The guide pillar that described cover has polyurethane packing ring and a steel washer passes from be arranged on the guide pin bushing the guide pin bushing installing hole of die ontology; Described guide pillar lower end fixedly mounts holding pad by screw.

Between described screw and holding pad, there is screw pad.

Described guide pillar upper end has diameter to be greater than the disk of guide pillar cylinder.

The pressure source of described holding pad pressure is nitrogen cylinder.

The course of work of the present utility model: the limit journey groove of making according to actual needs guide pillar patrix; When work, first polyurethane packing ring and steel washer are enclosed within on guide pillar, then guide pin bushing is arranged in the guide pin bushing installing hole of die ontology, the guide pillar with polyurethane packing ring and steel washer is passed from guide pin bushing; Then by the limit journey groove location of stroke limit plate alignment guide post, be fixed on and on die ontology, push down guide pin bushing; With screw, holding pad is fixed on guide pillar again; During work, utilize the limit journey groove on stroke limit plate and guide pillar to limit journey, integrated disc portions and urethane pad that guide pillar upper end diameter is large enclose safety effect.

Superiority of the present utility model: the utility model is leading and limitting journey to combine and make an assembly, realize the double action of guiding and limit journey, solved when the holding pad of mould adopts steel plate, holding pad thickness does not have the so thick difficult problem that causes installing guiding parts of ironcasting.
