Abstract
The invention relates to a sand core string device and a method thereof. The sand core string device comprises a plurality of sections or a plurality of blocks of sand cores, a hollow shaft, fastening nuts and glands and is used for sand core making in the casting process; the plurality of sections or the plurality of blocks of sand cores have a mutual positioning relationship, and a connecting through hole is formed in the middle of each sand core; the hollow shaft passes through the connecting through holes of all the sand cores, and the glands and the fastening nuts are respectively mounted at the two ends of the hollow shaft, therefore, the sand cores are clamped to form a string whole. The method comprises the following steps: dividing the ultra-long sand core into the plurality of sections or the plurality of blocks of sand cores having the mutual positioning relationship as required, enabling the hollow shaft to pass through the connecting through holes of all the divided sand cores, connecting all the sand cores according to the mutual positioning relationship and clamping the sand cores at the two ends of the hollow shaft by respectively using the glands and the fastening nuts to form the string whole. The sand core string device and the method thereof have the benefits that the problem that the ultra-long sand core and the multi-block combined sand core are limited in the making of the sand cores is solved, and the sand core string device has the advantages of good operability, high convenience, high convenience and reliability in disassembly and assembly, good reusability and relatively ideal practical effect.
Description
Technical field
The invention belongs to metallurgical casting industry, particularly relate to a kind of device of core string group and the method for core string group.
Background technology
In Foundry Production, usually have the core of overlength form and polylith combining form, especially overlength form core cannot make by the restriction of technological equipment, generally therefore can abandon the manufacture of this series products; Secondly in this type of core process of making, also because the operation of complexity may produce some other problems.
How to improve this situation, and economical, effectively, utilize the method for core string group by originally do not possess operability, the situation of complicated operation makes it to have operability, judicial convenience, be then a kind of method preferably.
Summary of the invention
Task of the present invention is to provide a kind of core string group devices and methods therefor, utilizes string group after first segmentation, solves the problem that overlength form and polylith combining form core in above-mentioned prior art are limited in the mill.
Technical solution of the present invention is as follows:
A kind of core string group device, it comprises core, and it also comprises hollow shaft, clamp nut and gland, makes for casting process core;
Described core is several sections or the several piece core with mutual positioning relation, is provided with connection through hole in the middle of each core;
Described hollow shaft, through the connection through hole of each core, installs gland and clamp nut respectively at the two ends of hollow shaft, clamps core thus and forms a string group entirety.
Be connected by bonding between described each core and adjacent core.
Mutual positioning relation between described core and core is by being fitting to connection.
A kind of core string prescription method implementing described core string group device, overlength form core is divided on demand several sections or several piece core of phase mutual positioning relation, by hollow shaft through connecting through hole in the middle of each segmentation core and making each core connect by mutual positioning relation, form a string group with gland and clamp nut clamping core respectively at the two ends of hollow shaft overall.
Bond between described each core and adjacent core and be connected.
Mutual positioning relation between described core and core is fitting connection form.
Core string group devices and methods therefor of the present invention utilizes string group after first segmentation, solves overlength form and the limited in the mill problem of polylith combining form core.This method is used for casting process core and makes, and operability is good, convenient, and loads and unloads reliably convenient, and utensil durability used is good, has ideal practical function.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of core string group device of the present invention.
Reference numeral:
1 is hollow shaft, and 2 is clamp nut, and 3 is gland, and 4 is core.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is elaborated.
Referring to Fig. 1, the invention provides a kind of core string group device, it forms primarily of core 4, hollow shaft 1, clamp nut 2 and gland 3, makes for casting process core.
Core 4 is several sections or the several piece core with mutual positioning relation, is provided with connection through hole in the middle of each core 4.Hollow shaft 1, through the connection through hole of each core 4, installs gland 3 and clamp nut 2 respectively at the two ends of hollow shaft 1, clamp core 4 thus and form a string group entirety.
Be connected by bonding between each core 4 with adjacent core.Mutual positioning relation between core 4 and core is by being fitting to connection, and also can be assembly connection.
In order to save material, hollow shaft 1 can reclaim and reuse.
The present invention also provides a kind of core string prescription method, overlength form core is divided on demand several sections or several piece core 4 of phase mutual positioning relation, by hollow shaft 1 through connecting through hole in the middle of each segmentation core 4 and making each core 4 connect by mutual positioning relation, clamp core 4 with gland 3 and clamp nut 4 respectively at the two ends of hollow shaft 1 and form a string group entirety, easy to make.
Bond between each core 4 with adjacent core and be connected.Mutual positioning relation between core 4 and core is fitting connection form.
In sum, core string group devices and methods therefor of the present invention utilizes string group after first segmentation, solves overlength form and the limited in the mill problem of polylith combining form core.This method is used for casting process core and makes, and operability is good, convenient, and loads and unloads reliably convenient, and utensil durability used is good, has ideal practical function.
Certainly, those skilled in the art in the art will be appreciated that, above-described embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, the change, modification etc. of above-described embodiment all will be dropped in the scope of the claims in the present invention.
