Abstract
A kind of ram-jolt molding sand device, it is characterized in that: comprise the bracing frame be made up of four root posts, support frame as described above upper end is provided with four cylindrical leads, described lead is connected with workbench, the corner of described workbench is provided with four manholes, the upper end of described lead is located in described manhole, support frame as described above middle part is connected with bracket, described bracket upper end is bolted to connection the bottom surface at workbench, described bracket is provided with spill wheel, described spill wheel side is provided with cam, and described cam is connected with gearbox.The utility model is by the free-falling of workbench and clash into the motion of bracing frame, the molding sand in fixing sandbox on the table and sandbox is impelled also to carry out same motion, by percussion movement, the molding sand in sandbox can be made to obtain consolidation under gravity, replace artificial manual consolidation molding sand, reduce the labour intensity of workman, enhance productivity.
Description
Technical field
The utility model relates to casting technology field, is specifically related to a kind of ram-jolt molding sand device.
Background technology
Casting is cast to by liquid metals in the casting cavity that adapts with part shape, after its cooled and solidified, to obtain the method for part or blank.Mostly be by casting material matter and be solid-state originally but be heated to liquid metal (example: copper, iron, aluminium, tin, lead etc.).The casting mold of conventional cast has molding sand, resin, waterglass etc.The casting mold of Special Processes of Metal Castings has: model casting, lost foam casting, permanent mold casting etc.In ordinary sand casting, model is put in sandbox, then fill sandbox with molding sand.Consolidation to be carried out to sandbox after having filled, so just model can be taken out with to be cast.The mode of consolidation has a variety of, have mechanical consolidation and artificial consolidation point.For the foundry production line of small lot, be mostly manually by simple ram-jolt instrument and tamping tool to realize molding sand consolidation, the mode of artificial consolidation then increases the labour intensity of moulding workman, also production efficiency is reduced to a certain extent, if sandbox has reinforcement, the efficiency of artificial consolidation can be lower.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of labour intensity reducing workman, improves the ram-jolt molding sand device of moulding production efficiency.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of ram-jolt molding sand device, comprise the bracing frame be made up of four root posts, support frame as described above upper end is provided with four cylindrical leads, described lead is connected with workbench, the corner of described workbench is provided with four manholes, the upper end of described lead is located in described manhole, support frame as described above middle part is connected with bracket, described bracket upper end is bolted to connection the bottom surface at workbench, described bracket is provided with spill wheel, described spill wheel side is provided with cam, and described cam is connected with gearbox.
Four leads on support frame as described above match with the manhole on workbench four angular range, for the smooth free-falling of workbench during guarantee work, leave certain gap between cooperatively interacting, the diameter that the diameter of lead is less than manhole is about 1-2 millimeter.
Described bracket and workbench are undertaken affixed by four bolts.
The spill wheel moved up and down during work can not touch cam, and in other words, spill wheel is greater than with the central horizontal distance of cam the radius sum that spill takes turns maximum radius and cam intermediate cylindrical position.
For improving the ram-jolt efficiency of this device, cam makes symmetrical form, and namely cam rotates one week, can realize twice ram-jolt effect.
During work, populated molding sand treated that consolidation sandbox is put on workbench, and fixed; Cam rotates under the drive of gearbox, the cam of rotation by with spill take turns 4 engaging, bracket is moved upward, and workbench also just moves upward.When cam and spill take turns be separated time, now workbench arrive highest point, both be separated after, workbench free-falling, strikes on bracing frame.Under the effect of impulsive force, molding sand obtains consolidation.Along with the not stall of cam is moved, workbench multiple impact bracing frame, the molding sand in sandbox obtains consolidation.
The beneficial effects of the utility model are:
1. the utility model clashes into the motion of bracing frame by the free-falling of workbench, the molding sand in fixing sandbox on the table and sandbox is impelled also to carry out same motion, by percussion movement, the molding sand in sandbox can be made to obtain consolidation under gravity, replace artificial manual consolidation molding sand, reduce the labour intensity of workman, enhance productivity.
2. all applicable for multi-form sandbox, the sandbox (such as with the sandbox of reinforcement) that especially structure is comparatively complicated
3. device is simple, simple for structure, is easy to realize.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is utility model works state diagram;
Fig. 3 is the utility model spill wheel and cam position graph of a relation.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1-3:
A kind of ram-jolt molding sand device, comprise the bracing frame 1 be made up of four root posts, bracing frame 1 upper end is provided with four cylindrical leads 8, lead 8 is connected with workbench 7, and the corner of workbench 7 is provided with four manholes, the upper end of lead 8 is located in described manhole, bracing frame 1 middle part is connected with bracket 3, and bracket 3 upper end is fixedly connected on the bottom surface of workbench 7 by bolt 2, bracket 3 is provided with spill wheel 4, spill is taken turns 4 sides and is provided with cam 5, and cam 5 is connected with gearbox 6.Four leads 8 on bracing frame 1 match with the manhole on workbench 7 four angular range, for the smooth free-falling of workbench 7 during guarantee work, certain gap is left between cooperatively interacting, the diameter that the diameter of lead 8 is less than manhole is about 1-2 millimeter, and bracket 3 and workbench 7 are undertaken affixed by four bolts 2.
The spill wheel 4 moved up and down during work can not touch cam 5, and in other words, spill wheel 4 is greater than the radius R sum that spill takes turns 4 maximum radius r and cam 5 intermediate cylindrical position, L>r+R with the central horizontal distance L of cam 5).For improving the ram-jolt efficiency of this device, cam 5 makes symmetrical form, and namely cam 5 rotates one week, can realize twice ram-jolt effect.
During work, populated molding sand 9 treated that consolidation sandbox 10 is put on workbench 7, and fixed, cam 5 rotates under the drive of gearbox 6, the cam 5 of rotation by with spill take turns 4 engaging, bracket 3 is moved upward, and workbench 7 also just moves upward.When cam 5 and spill take turns 4 be separated time, now workbench 7 arrives highest point, both be separated after, workbench 7 free-falling, strikes on bracing frame 1, and under the effect of impulsive force, molding sand 9 obtains consolidation.Along with the not stall of cam 5 is moved, workbench 7 multiple impact bracing frame 1, the molding sand 9 in sandbox 10 obtains consolidation.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
