Description
Technical field
The utility model relates to foam cutter sweep field, is specifically related to a kind of special-shaped foam cutting machine.
Background technology
Foam is also known as EPS(expandable polystyrene), there is light weight, inexpensive, thermal conductivity is low, water imbibition is little, the advantage such as electrical insulation capability is good, sound insulation, shockproof, moistureproof, moulding process is simple, be thus widely used in the fields such as building, chemical industry, metallurgy.In field of metallurgy, foam is widely used in lost foam casting (apperance used adopts foam (EPS) sheet fabrication to make, and adopts clay-bonded sand moulding, is used for producing art work foundry goods) technique; Because foundry goods size, shape etc. in casting (refer to solid metallic to dissolve for liquid state pours the apperance of given shape into, treat the processing mode of its solidification forming) are all not identical, so complete the cutting processing of Foam Pattern under foam cutting machine must be used.
Foam cutting machine comprises the Cutting platform for cutting Foam Pattern, Cutting platform both sides are slidably fitted with the first support arm and the second support arm, and be connected with heating wire between two support arms, wherein the power supply that promising heating wire provides electric energy is installed in the bottom of the first support arm.
At present, the foam cutting machine that most domestic Foundry Works uses, the cutting on surface all can only be carried out to foam, processing cutting cannot be carried out to the hole on foam, cause when cutting some and being with pertusate Foam Pattern, could process the hole cutting the center after first Foam Pattern must being cut, subsequently again by manually in foam incision spreading glue, make in its adhesion.But when artificial spreading glue, likely smear uneven, cause when foam adhesion, occur that adhesion is loosely, and then the adhesion foam of incision misplaces, and hole is deformed; When causing the later stage to cast, the molten metal of casting is injected in the hole of distortion, forms underproof cast, adds the percent defective of cast.
Most of foam cutting machine can only be installed the heating wire in a direction simultaneously, the cutting machine of vertical direction heating wire has such as been installed, just horizontal heating wire can not be installed, because the heating wire of vertical direction is when moving horizontally cutting, very easily directly clash into horizontal heating wire, cause the short circuit of cutting loop; Therefore, present most of cutting machine only has the cutting function in a direction.
In sum, being badly in need of now a kind of when processing the hole in Foam Pattern, just can directly processing without slit foam apperance; And the compatible foam cutting machine of heating wire of energy both direction.
Utility model content
The utility model is intended to provide a kind of when processing the hole in Foam Pattern, just can directly process without slit foam apperance; And the compatible special-shaped foam cutting machine of heating wire of energy both direction.
This programme special-shaped foam cutting machine, comprises the support arm being positioned at cutting arm both sides, and is connected with the first heating wire between support arm; Also comprise the cutting arm be positioned at above Cutting platform, cutting arm comprise forearm and and the postbrachium hinged with forearm, the front end of described forearm is provided with driving mechanism, driving mechanism slidably connects the second heating wire, and the second heating wire is just to Cutting platform; The lower rotation of described postbrachium is connected on Cutting platform side.
The length of described postbrachium is at least 1.1 times of forearm, and the arm of postbrachium is provided with the groove matched with forearm with it; Described forearm front end is also provided with the motor be rotationally connected with driving mechanism simultaneously, and the end of postbrachium is provided with a pair orthogonal first limited block, Cutting platform side be provided with to the second limited block coordinated.
The operation principle of this programme and beneficial effect: due to the effect of driving mechanism, under the drive of motor, can realize the relative Cutting platform of the second heating wire produce near or away from effect; By away from produced distance, relevant position is placed on needing the Foam Pattern of punching, second heating wire is close to Cutting platform subsequently, and be inserted in Foam Pattern, by passing through electric current to the second heating wire, make it produce heat, because the fusing point of foam itself is lower, under the effect of heat, make the foam melts of the second heating wire and Foam Pattern contact position, and then complete the cutting to the hole in Foam Pattern.After cutting to be punctured completes, first extract the second heating wire out, pressing down forearm, make forearm be pressed in groove, be pressed completely into after groove until forearm, just rotatable postbrachium, makes postbrachium half-twist; Add the effect that the first limited block and the second limited block contact with each other, postbrachium can be stoped to continue to rotate after half-twist.Adopt this programme, the Foam Pattern that need punch not only can be avoided to cut, and then decrease the distortion of hole, have influence on the quality of cast; By pressing down forearm and rotating postbrachium, cutting arm can being packed up, decreasing cutting arm when not using, the area shared by it simultaneously.
Further, also comprise the contact hole matched with the second heating wire, and be positioned on Cutting platform, the radial direction of described contact hole is at least provided with two panels metal clips; When the termination of the second heating wire is inserted into contact hole, if without metal clips, the likely loose contact of the second heating wire and contact hole, causes the open circuit of cutting loop; And metal clips can avoid the situation of the loose contact of the second heating wire and contact hole to produce.
Further, the compressing member can fixing the second heating wire is provided with in described contact hole; When the personnel of cutting are when cutting Foam Pattern, can to Foam Pattern applied thrust meeting pulling force, if the second heating wire is not secured in a press, under the thrust being just easy to early cutting personnel or pulling force, pull out from contact hole, cause the open circuit of cutting loop, and easily cause the distortion of the second heating wire or fractureed.
Further, described compressing member comprise movable compressing tablet and with the fixing compressing tablet that movable compressing tablet is arranged side by side, movable compressing tablet is connected with the hydraulic pump be arranged on Cutting platform; The outer of described movable compressing tablet is provided with the semi-circular through hole matched with the second heating wire, and fixing compressing tablet outer is also provided with the semi-circular through hole matched with movable compressing tablet; By the movement of movable compressing tablet, can when the second heating wire insert, decrease the second heating wire when inserting manhole, the contact of itself and compressing member, and then avoid the second heating wire and be bent or break, have influence on the cutting in later stage.
Further, the inwall of described semi-circular through hole is evenly equipped with anti-slop serrations; Increase the frictional force of the second heating wire and movable compressing tablet and fixing compressing tablet, avoid cutting personnel when cutting Foam Pattern, the second heating wire rotates.
