Abstract
The utility model discloses a moulding model for a scaffold fastener assembly. The moulding model is composed of moulding sand, an outer frame, and the assembly cavity of scaffold fasteners, wherein the moulding sand is filled in the outer frame of a sand mould; the assembly cavity is stamped in the moulding sand; the connector cavity of the assembly is stamped in one side of the assembly cavity; a casting hole for molten iron is machined above the sand mould; the casting hole is connected with a molten iron casting channel; the molten iron casting channel is connected with the assembly cavity; clay core cavities are stamped in the middles of the both sides of the connector cavity of the assembly; cylindrical clay cores are placed in the clay core cavities; and the clay cores penetrate through the clay core cavities at the both sides of the connector cavity of the assembly. Because the clay cores penetrate through the clay core cavities, the molten iron is separated at the centre part of a connector to form a connecting hole during casting, and the connecting holes of all the cast assemblies easily realize uniform standards, and consistent size and axial direction, thus greatly improving the quality of the product; and the connecting holes are cast and formed in one step, thus avoiding manually re-perforating in the products, and machining equipment and production personnel for the assemblies are greatly reduced, thus greatly reducing the production cost.
Description
Technical field
The utility model belongs to the fastener manufacturing technology field that steel pipe scaffold is used in construction, relates to a kind of founding model of various component parts of scaffold clasp.
Background technology
In construction, need to scaffold erecting with steel pipe and construct, need to use fastener to connect between the steel pipe that scaffolds erecting, connection fastener commonly used has three kinds of pair clasp, right-angle coupler and rotary buckles, the primary clustering of three kinds of fasteners comprises Connection Block and tightening cover, have connecting hole on each assembly connector, each forms the formation fastener that links together with rivet by connecting hole.The Connection Block of three kinds of fasteners and tightening cover shape are different, and its purposes is consistent, supports the use.In three kinds of fasteners, the primary clusterings such as Connection Block, bar core, inner cap, enclosing cover and cover plate adopt the disposable casting forming of malleable iron material, it is better that the malleable iron material product has cutting ability, corrosion resisting property and heat resistance, the advantage that the low temperature tough brittle transition temperature is low has higher intensity and toughness, again very high vibration damping and percentage elongation is preferably arranged.
When casting bar core, inner cap, enclosing cover, the several primary clustering of cover plate, adopt the founding model to cast, in prior art, the founding model of several primary clusterings is comprised of molding sand, housing and the assembly cavity that forms subassembly product, molding sand is filled in the housing of sand mold, the punching press of assembly cavity is in molding sand, the other punching press of assembly cavity has the connector die cavity of assembly, the as a whole cavity of this cavity, leave the tapping hole of molten iron above sand mold, punching press has the pouring channel of molten iron in sand mold, molten iron pouring channel coupling assembling cavity.
Adopt this sand casting fastener assembly out, connector on assembly is a solid nahlock, assembly will with the bench drill punching on solid nahlock connector, could fit together each assembly to use with rivet after punching and make fastener when post-production.When boring, method commonly used is that single fastener assembly is fixed on bench drill, holes one by one.This processing method, workpiece will carry out single Drilling operation, needs to drop into a large amount of bench drill and operating personnel, and its labour intensity is large, and production efficiency is low, and production cost is high.In process, when operating personnel hole on connector, bore position and axially very difficult control, the axial inconsistent quality problems that bore position skew, boring easily occur, the problematic fastener assembly of this drilling quality in use, can cause the even situation of fastener component assembling difficulty or connector wall unevenness to occur, cause the situation that the fastener assembly bursts in use to occur.
Summary of the invention
the utility model is for prior art, in the founding model of the chief component part of all kinds of fasteners of steel pipe scaffold, the as a whole cavity of connector die cavity of fastener assembly, casting fastener assembly connector out is a solid nahlock, connector needs thereon punching separately when post-production, cause production efficiency low, labour intensity is large, production cost is high, the situation of quality problems easily appears in the fastener assembly, a kind of founding model of scaffold clasp assembly is provided, this founding model is by molding sand, the cavity of housing and scaffold clasp assembly forms, molding sand is filled in the housing of sand mold, punching press has the cavity of fastener assembly in molding sand, one side blow of the cavity of fastener assembly is pressed with fastener assembly connector cavity, be processed with the tapping hole of molten iron above sand mold, molten iron flows into pouring channel by tapping hole, tapping hole is connected with the molten iron pouring channel, the cavity of molten iron pouring channel connection fastener assembly, in the two middle side part punching presses of fastener assembly connector cavity, the loam core cavity is arranged, be placed with columniform loam core in the cavity of loam core, the loam core connects the loam core cavity of fastener assembly connector cavity both sides.
The loam core can be formed by precoated sand, damp sand or the compacting of waterglass quartz sand.
Adopt technique scheme, because the both sides of connector cavity in sand mold are designed with the loam core cavity, be placed with columniform loam core in the cavity of loam core, the loam core connects the connector cavity, when molten iron is cast, a lead to the hole site is occupied out in the connector centre in the loam core, separates molten iron after casting on the connector of loam core, forms a connecting hole; Because the loam core is with the diameter circle cylindricality, the loam core cavity is the coaxial cylindrical cell body cavity that once stamps out, and after the molten iron casting, the connecting hole size that casts out is with axially consistent, and all casting fastener assembly connecting hole standards are unified, and product quality is higher; Due to casting forming of connecting hole, avoided the manually punching again on product, process equipment and the producers of fastener assembly greatly reduce, and production cost reduces greatly.
