Compared with the prior art, can be according to the welding demand of difference to select or change the die cavity mold insert that has different ebonite layers, can adjust coefficient of friction, need not adjust whole die block like in the past, reduce manufacturing cost, improved work efficiency, strengthened the suitability of friction welding mould, solved the problem that the drunkenness phenomenon appears easily when the product is friction welding, appear scotch or unable welded problem when having avoided the welding.
Description
Technical Field
The utility model relates to a friction die technical field, concretely relates to die cavity material adjustable friction welding mould.
Background
The bottom die of the conventional friction welding die is usually of an integral structure, a PU (polyurethane) adhesive material covered on the surface of the bottom die can not be adjusted once being cured, and when the friction coefficient of the surface material is lower, the phenomenon of play of a female die formed or coated product is easy to occur in the die due to the fact that the female die formed or coated product is thinner and low in rigidity, so that the product appearance is scratched and the like, and even the product can not be welded in serious cases. Therefore, different friction coefficients are adjusted by replacing different friction molds, so that welding requirements of different products are met, and for different products, multiple sets of friction molds need to be arranged due to the fact that the materials of the existing friction welding mold cavities are not adjustable, so that the production cost is high, and the production efficiency is low.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to be not enough among the prior art, and provide a die cavity material adjustable friction welding mould.
The purpose of the utility model is realized through the following technical scheme: the application provides a friction welding mould of die cavity material adjustable, including the die block, the piecemeal die cavity has been seted up to the die block, and detachably installs two at least die cavity inserts in the piecemeal die cavity, and the top surface of each die cavity insert is all pasted and is covered and have the ebonite layer.
Wherein, a plurality of direction counter bores up have been seted up to the bottom surface of die block, and each counter bore all communicates with the piecemeal die cavity, and the screw hole that aligns with the counter bore is all seted up to the bottom surface of each die cavity mold insert, and the die cavity mold insert passes through connecting bolt fixed mounting in the piecemeal die cavity.
Wherein, the counter sink includes countersunk head portion, and connecting bolt includes pole portion and head, and the periphery side of pole portion is equipped with the external screw thread with screw hole threaded connection, and under the assembled state, connecting bolt's head card is held in the countersunk head portion.
Wherein, the hard glue layer is a PU glue layer.
The utility model has the advantages that: in the preparation process of the friction welding mold with the adjustable cavity material, a welding pressed area of a bottom mold in the mold is provided with a blocking cavity, and a cavity insert pasted with a hard glue layer is detachably connected into the blocking cavity, so that the bottom mold can be assembled;
compared with the prior art, can be according to the welding demand of difference to select or change the die cavity mold insert that has different ebonite layers, can adjust coefficient of friction, need not adjust whole die block like in the past, reduce manufacturing cost, improved work efficiency, strengthened the suitability of friction welding mould, solved the problem that the drunkenness phenomenon appears easily when the product is friction welding, appear scotch or unable welded problem when having avoided the welding.
Drawings
The present invention is further explained by using the drawings, but the embodiments in the drawings do not constitute any limitation to the present invention, and for those skilled in the art, other drawings can be obtained according to the following drawings without any inventive work.
Fig. 1 is a schematic partial structure diagram of a friction welding mold in this embodiment.
Fig. 2 is a sectional view of the friction welding mold in this embodiment.
Fig. 3 is an enlarged view of a portion a in fig. 2.
Description of the drawings: the die comprises a male die 10, a bottom die 1, a partitioning cavity 11, a counter bore 12, a cavity insert 2, a threaded hole 21, a connecting bolt 3 and a hard glue layer 4.
Detailed Description
The invention will be further described with reference to the following examples.
The utility model discloses a friction welding mould's of die cavity material adjustable specific implementation mode please see fig. 1 to 3 and show, including formpiston 10 and die block 1, die block cavity 11 has been seted up to die block 1, and two at least die cavity mold inserts 2 are installed to detachably in the die block cavity 11, and the top surface of each die cavity mold insert 2 is all pasted and is covered and have ebonite layer 4.
Preferably, referring to fig. 2, a plurality of countersunk holes 12 facing upward are formed in the bottom surface of the bottom die 1, each countersunk hole 12 communicates with the block cavity 11, a threaded hole 21 aligned with the countersunk hole 12 is formed in the bottom surface of each cavity insert 2, and the cavity insert 2 is fixedly mounted in the block cavity 11 through a connecting bolt 3. Threaded detachable structure can carry out the dismouting to die cavity mold insert 2 fast, improves the convenience when changing or examining and repairing, and in addition, threaded detachable structure can also provide higher joint strength, further prevents that the product from taking place the drunkenness in welding process.
In this embodiment, the countersunk hole 12 includes a countersunk head portion, the connecting bolt 3 includes a rod portion and a head portion, the outer peripheral side surface of the rod portion is provided with an external thread in threaded connection with the threaded hole 21, and the head portion of the connecting bolt 3 is held in the countersunk head portion in an assembled state.
In the present embodiment, the hard adhesive layer 4 is a PU adhesive layer. It should be noted that PU glue is the most common hard glue layer 4 in the field of friction welding dies, and its function and structure are readily known to those skilled in the art.
In the preparation process of the friction welding mold with the adjustable cavity material, a blocking cavity 11 is formed in a welding pressure area of a bottom mold 1 in the mold, and a cavity insert 2 attached with a hard glue layer 4 is detachably connected into the blocking cavity 11, so that the bottom mold 1 can be assembled. Compared with the prior art, can be according to the welding demand of difference to select or change the die cavity mold insert 2 that has different ebonite layers 4, can adjust coefficient of friction, need not adjust whole die block 1 like in the past, reduce manufacturing cost, improve work efficiency, strengthened the suitability of friction welding mould, solved the problem that the drunkenness phenomenon appears easily when the product carries out friction welding, appear scotching or unable welded problem when having avoided the welding.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
