Description
Technical field
The utility model relates to commutator manufacturing and processing equipment, is specifically related to a kind of for processing the crowded hook pin equipment of Hooked reverser.
Background technology
In commutator field, so-called " squeezing hook pin ", Hooked reverser hook pin inner side is squeezed into fillet.By calculating, can show that the changes of section amount of the commutator enamelled wire that does not squeeze hook is more much bigger than the commutator of crowded hook, after the commutator spot welding of crowded hook, in hook pin both sides, there is not obvious shearing phenomenon simultaneously, thereby make electric current huge change occur cross section when by spot welding region, the in the situation that of fully loaded or overload operation, the bad phenomenon such as the enamelled wire of commutator hook pin both sides will generate heat, burn, thus motor is damaged.
And for the commutator that squeezes hook pin, the changes of section amount of enamelled wire is compared with enamelled wire original before spot welding not without obvious changes of section, and welding position is without shearing phenomenon.In actual client's use procedure, once there is so together event: certain company is in spot welding wherein during a motor, unexpectedly the thickness of hook pin is deformed into 0.3 left and right by 0.9 spot welding, and the wire gauge of enamelled wire is only 0.13 line, enamelled wire is played out unexpectedly to find that enamelled wire has been flat while checking also not disconnected, the benefit of squeezing as can be seen here hook pin.At present, for spot-welding technology, still the very ripe final conclusion of neither one, the point quality of each producer in working control is uneven, and squeeze hook pin technique, can make the technology difficulty of spot welding reduce at least one times, through the actual use proof of a plurality of producers, squeezing hook product can be enhanced about more than once than the life-span of not squeezing hook product.
Therefore, extremely need to have a process equipment that squeezes hook pin that is specifically designed to.
Summary of the invention
The utility model is processed existing technical problem mainly for the cheicers of commutator, has invented a kind of crowded hook pin equipment that is specifically designed to processing Hooked reverser, and this equipment adopts the mode of mould extruding to make the moulding of cheicers crushing failure at high speed.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs: a kind of crowded hook pin equipment, comprise frame, board panel by frame support, it is characterized in that, on board panel, be provided with the lower bolster of level, on lower bolster, be provided with the core rod of a vertical axes shape, the vertical die of peripheral ring set one of core rod, die integral body is the column of hollow, its top is up-narrow and down-wide truncated cone shape, interlude is cylindrical, bottom is the pedestal of truncated conical shape, die by some crowded hook pin matrixs according to circumference, radial arrangement is formed by connecting, between adjacent crowded hook pin matrix, retain space, pedestal is fixed in the lower end of squeezing hook pin matrix, the concave surface that each crowded hook pin matrix end face is inwards arranged to concave.
The top of described die is provided with the cope match-plate pattern of a level, and the position of vertically aliging in cope match-plate pattern, with die is provided with cope match-plate pattern mold insert, the collar shape that cope match-plate pattern mold insert is hollow, and this hollow space is up-narrow and down-wide truncated cone shape.
Above-mentioned cope match-plate pattern mold insert tapering is identical with die top tapering, in squeezing the process of hook pin, cope match-plate pattern mold insert is along with cope match-plate pattern moves down into the upper end of die, and ring set is on die, die is produced to squeezing action, and the crowded hook pin matrix that forms die shrinks to center.
The below of described board panel is provided with cylinder, the piston rod of cylinder vertically upward and on piston rod, be fixed with joint cover, between this joint cover and described cope match-plate pattern, be connected with some pull bars, pull bar vertically, through board panel and lower bolster, is provided with elastic recovery assembly between described cope match-plate pattern and lower bolster.
The effect of cylinder is cope match-plate pattern drop-down, and after completing the action of squeezing hook pin, cylinder is replied, and the active force of cope match-plate pattern is disappeared, and now, elastic recovery assembly produces restoring force, will on arm-tie, be pushed into original position.
As preferably, described elastic recovery assembly comprises top bullet piece reference column and top bullet piece, wherein, top bullet piece reference column is vertically fixed on lower bolster, connection top, the upper end bullet piece of top bullet piece reference column, described top bullet piece is elastomeric material, such as excellent power rod, rubber bar etc.Under the effect of cope match-plate pattern at cylinder when moving down and pushing down top bullet piece, top bullet piece compression; When cylinder homing, when pulling force disappears, the elastic-restoring force of top bullet piece starts to have an effect, by pushed home on cope match-plate pattern.
As preferably, between described cope match-plate pattern and lower bolster, be provided with guidance set, as the guide pin bushing of hollow, vertical guide pillar etc.The effect of guidance set is auxiliary connecting rod, maintains cope match-plate pattern moving up and down of balance and stability more.
As preferably, between described cope match-plate pattern and lower bolster, be provided with stopping means, as limited post, gag lever post etc. are set, limit assembly moves down distance for controlling the maximum of cope match-plate pattern, because moving down apart from the shrinkage degree that has determined die integral body of lower bolster, and the shrinkage degree of die is different, also just different to the extruding dynamics of commutator, so, limited post is set and can avoids commutator to be extruded excessively.
As preferably, on described joint cover or in frame, be provided with induction installation.Induction installation is set, for the startup of Based Intelligent Control cylinder with close.
In sum, the utility model compared with prior art tool have the following advantages:
The utility model is the equipment that is specifically designed to extruding cheicers, and the mode that adopts mould to push makes the cheicers crushing failure at high speed moulding of commutator.
