Description

A kind of core rounding instrument

Technical field

This utility model is related to sand cores of castings, more particularly, to a kind of core rounding instrument.

Background technology

Existing great majority sporadicly foundry goods, its model mostly is simple wooden model model or simple wooden model concrement vacuole mould, in core box Curving of castings model is not made, and is polished using manually using grinding wheel or emery cloth.This job demand substantial amounts of man-hour completes, with The operant skill of Shi Yaoqiu workman is high.Indivedual parts make foundry goods crack because fillet polishing in local is less, and subsequent quality is processed Bring very burden；If it is excessive that fillet is polished, many pouring molten iron foundry goods must be made to increase weight, cause damage.Existing polishing side Formula is unstable, and efficiency is low, and it cannot be guaranteed that polishing quality, needs to be improved.

Utility model content

This utility model provides a kind of core rounding instrument, not enough to solve above-mentioned prior art, improves and falls on core The curving of castings quality going out, improves chamfering speed soon, saves operative's man-hour, improve production efficiency.

The technical solution adopted in the utility model is：

A kind of core rounding instrument, including die cylinder and die flat board, in die cylinder one end and die flat board The heart is welded to connect, die flat board be provided with four arc surfaces side week, the arc radius of two of which arc surface are 20 ~ 30mm, separately The arc radius of outer two arc surfaces are 10 ~ 20mm, and arc surface is all coated with the zinc layers of 0.2 ~ 0.5mm, the thickness of die flat board For 4 ~ 10mm.The stage casing of die cylinder is additionally provided with a circle rubber layer.The strip bulge of inclination had on rubber layer, height of projection 0.5 ~ 1mm, ledge width 0.5 ~ 1mm.

The beneficial effects of the utility model are：

Obtain die flat board as a kind of chamfer tool using four arc-shaped surfaces of die cylinder welded bands, cylinder is fixed Afterwards, can four objects be polished simultaneously；And two of which arc surface can be designed as arc radius according to the actual requirements Arc surface for 20 ~ 30mm, two other can be designed as the arc surface that arc radius are 10 ~ 20mm, root according to the actual requirements Design according to actual demand can carry out different size of rounding simultaneously, practical, greatly improves chamfering speed, saves Operative's man-hour, improve production efficiency.Die flat board is designed as 4 ~ 10mm thickness according to demand, is conducive to improving chamfering matter Amount；Zinc coat is conducive to improving the die degree of arc surface, improves the stability of buffed surface, and life-time service does not interfere with polishing yet Quality, improves the life-span of instrument；The setting of rubber layer can provide a kind of hand-held mode for this instrument, under special circumstances Need to carry out providing when hand-held tackles single object a kind of scheme, and the strip bulge by tilting, permissible Guarantee that hand-held effect is good, improve degree of being affectedly bashful, prevent from further skidding, be conducive to hand-held exerting oneself.This tool construction simple it is easy to real Apply.

Brief description

Fig. 1 is this utility model structural representation one.

Fig. 2 is this utility model structural representation two.

Specific embodiment

As shown in accompanying drawing 1 ~ 2, a kind of core rounding instrument, including die cylinder 1 and die flat board 2, die cylinder 1 one End be connected with the center weld of die flat board 2, die flat board 2 be provided with four arc surfaces 21, two of which arc surface 21 side week Arc radius be 20 ~ 30mm, the arc radius of two other arc surface 21 are 10 ~ 20mm, arc surface 21 is all coated with 0.2 ~ The zinc layers of 0.5mm, the thickness of die flat board 2 is 4 ~ 10mm.The stage casing of die cylinder 1 is additionally provided with a circle rubber layer 11.Rubber layer There are the strip bulge of inclination, height of projection 0.5 ~ 1mm, ledge width 0.5 ~ 1mm on 11.

Obtain die flat board 2 using die cylinder four arc surfaces 21 of 1 welded bands as a kind of chamfer tool, cylinder 1 is solid After fixed, can four objects be polished simultaneously；And two of which arc surface 21 can be designed as circular arc according to the actual requirements Radius is the arc surface 21 of 20 ~ 30mm, and two other can be designed as the circular arc that arc radius are 10 ~ 20mm according to the actual requirements Face 21, design according to the actual requirements can carry out different size of rounding simultaneously, practical, greatly improves chamfering speed Degree, saves operative's man-hour, improve production efficiency.Die flat board 2 is designed as 4 ~ 10mm thickness according to demand, is conducive to improving Chamfer quality；Zinc coat 3 is conducive to improving the die degree of arc surface, improves the stability of buffed surface, and life-time service also will not Impact polishing quality, improves the life-span of instrument；The setting of rubber layer 11 can be this instrument provide a kind of hand-held mode, be In particular cases need to carry out providing a kind of scheme, and the bar shaped by tilting when hand-held tackles single object Projection, it can be ensured that hand-held effect is good, improves degree of being affectedly bashful, and prevents from further skidding, and is conducive to hand-held exerting oneself.

This tool construction is simply it is easy to implement.
