Abstract

The invention discloses a casting process, in particular relates to a method for assembling and setting a core, comprising the following steps of: (1) preparing the core: producing scattered mud cores according to the requirement of castings; (2) transporting: placing the scattered mud cores on a transportation braced chain and transporting the scattered mud cores beside a clamp for automatically assembling and setting the core; and (3) assembling and setting the core: placing the scattered mud cores in the clamp for automatically assembling and setting the core and automatically assembling to be automatically assembled and placing the entire cores in a die cavity by the clamp for automatically assembling and setting the core. By using the invention, the core assembling procedures before the transportation procedure are integrated to a core setting procedure and the core assembly can be avoided after producing the core; and the core assembling and setting can be automatically finished by only transporting the small scattered cores beside a modeling line and feeding the small scattered cores in a core setting mould, thereby improving the production efficiency and reducing the cost for storing, transporting and transferring the mud cores.

Description

The method of core under a kind of automatic core assembly

Technical field

The present invention relates to a kind of casting technique, relate in particular to the method for core under a kind of automatic core assembly.

Background technology

The casting and molding line has higher production efficiency, good casting quality and casting quality is convenient to advantages such as control, along with China from casting big country to the striding forward of casting power, mo(u)lding line will be widely used in the Foundry Production field.Following core is the critical process on the casting and molding line, and as shown in Figure 1, the core jig of mo(u)lding line use at present just is installed with several locating pieces, can only bear the following core of whole core.Therefore, in traditional foundry technology process, the flow process of coremaking, core assembly, following these three operations of core is such: at first, make scattered little core, utilize the core assembly machine then, each scattered little core is formed whole core, will put in order core by supply line again and be transported to by the core jig, the core setter of finishing whole core by core jig is done at last.But can form cantilever behind some whole core core assembly, be transported to and under the gravity effect, easily produce distortion in the other process of core jig, and for the larger-size loam core of whole core, on the one hand, transportation is vulnerable to interfere from the core assembly Ministry of worker to core setter line limit, and means of transport is bigger relatively; On the other hand, must establish the core assembly operation, it is huger to deposit the core dolly, has increased to deposit the core cost.When especially whole core size differed greatly, little core storage and transhipment contradiction were more outstanding.

Summary of the invention

The objective of the invention is provides the method for core under a kind of automatic core assembly at top described problem, reduces the transportation difficulty in loam core, reduces production costs, and has shortened technological process, has improved automatic degree of production line.

The present invention is achieved by the following technical programs.

The method of core may further comprise the steps successively under a kind of automatic core assembly.

(1) coremaking produces scattered loam core according to the needs of foundry goods.

(2) transportation is positioned over scattered loam core on the transportation stretched wire, by the transportation stretched wire they is transported to by a kind of automatic core assembly core jig.

(3) core assembly and following core, with scattered loam core according to separately assembled relation, be positioned in a kind of automatic core assembly core jig, be assembled into whole core automatically, will put in order core automatically by a kind of automatic core assembly core jig at last and put into die cavity by a kind of automatic core assembly core jig.

The described a kind of automatic core assembly core jig in step (2) and (3) comprises core suspender and following core mold down, and described core mold down comprises base and locating piece, and locating piece is fixed on the base, wherein, also comprises driving slide block, core assembly cylinder, guide rod; Core assembly cylinder and guide rod are fixed on the base; The core assembly cylinder links to each other with the driving slide block; Drive slide block and be movably connected on the guide rod, drive the driving that slide block is subjected to the core assembly cylinder,, promote little core, finish the work of core assembly along the guide rod rectilinear motion.

On the described core assembly cylinder holding wire and tracheae are installed, link to each other with pneumatic control system with the core setter electric-control system respectively, the control program of setting by core setter carries out core assembly.

The invention has the beneficial effects as follows: the present invention drives slide block and guide rod by setting up the core assembly cylinder on the following core mold of core jig, and in the core setter control system corresponding increase core assembly cylinder control program, thereby make core jig have automatic core assembly function.So just the core assembly operation before the transportation operation can be incorporated into core setting, need not core assembly after the coremaking, only need scattered little core is transported to the mo(u)lding line limit, be lowered to down in the core mold, can finish core assembly and following core automatically, thereby improved production efficiency, the transportation of little core greatly reduces the cost of loam core storage and transhipment with respect to whole core.And because storage and transportation need not pre-core assembly, the problem on deformation of the whole core of cantilever has obtained solution, has well guaranteed its dimensional accuracy.

The specific embodiment

Further specify the structure and the occupation mode of the automatic core assembly core jig of the present invention below in conjunction with accompanying drawing.

As shown in Figure 1, traditional core jig only comprises base 1 and locating piece 2, does not have automatic core assembly function.

As shown in Figure 2, traditional core assembly core setter as process is: coremaking, core assembly, transportation, following core.

As shown in Figure 3, the method for core may further comprise the steps successively under a kind of automatic core assembly of the present invention.

As shown in Figure 4, the described a kind of automatic core assembly core jig in step (2) and (3) comprises core suspender and following core mold down, described core mold down comprises base 1 and locating piece 2, locating piece 2 is fixed on the base 1, wherein, also comprises driving slide block 21, core assembly cylinder 22, guide rod 23; Core assembly cylinder 22 is fixed on the base 1 with guide rod 23; Core assembly cylinder 22 links to each other with driving slide block 21; Drive the driving that slide block 21 is subjected to core assembly cylinder 22,, promote little core, finish the work of core assembly along guide rod 23 rectilinear motions.

Holding wire 24 and tracheae 25 are installed on the core assembly cylinder 22, link to each other with pneumatic control system with the core setter electric-control system respectively.

As shown in Figure 5, the course of work that is applied on the P471 gearbox of a kind of automatic core assembly core jig is as follows.

Corresponding increase core assembly cylinder control program in the core setter control system, thus make core jig have automatic core assembly function.After making, little core need not core assembly again, only scattered little core need be transported to by the core jig, be lowered to down in the core mold, and put the position of little core on request, after core setter sends the instruction of core assembly, drive the driving that slide block 21 is subjected to core assembly cylinder 22, along guide rod 23 rectilinear motions, promote little core, can finish core assembly automatically, core under the core suspender has improved production efficiency greatly under passing through at last.
