Summary of the invention

This reality is novel for the above-mentioned deficiency of solution, it is desirable to provide a kind of structure is simple, and it is easy to manufacture, lighter in weight, maintenance side Just a kind of head low with operating cost, is achieved using following technical scheme.

With one both ends of roll of steel plate cone not of uniform size, the large head external diameter size of cone is equal to the Inner of cylinder sleeve Diameter size, microcephaly's internal diameter come directly towards the width dimensions on maximum side slightly larger than the rear end of machine mouth, terminal pad and cone it is small Head outer rim fitting is linked together, head terminal pad be located at it is intermediate by after stud and nut with the terminal pad of cylinder sleeve front end top, The preceding terminal pad with machine mouth rear end top is that three-in-one be connected and fixed is integrated, and the rectangular billet that foundation extruder is squeezed out is wherein The heart is faster than the theorem of quadrangle, manufactures each one piece of arc line shaped triangle flow distribution plate and is placed in the left up and down of cone microcephaly Inner respectively The right side is later an angle, preceding（Before nearly machine mouth is）It is arranged for two angles, the centre between preceding two corners is inwardly projecting camber line Shape is outer fagging in the space between cone and cylinder sleeve, it is only necessary to suitably lengthen back cylinder sleeve and be used to install cone ?.

In conclusion the present invention the main points of its technical scheme are that：With one both ends of roll of steel plate cone not of uniform size, The large head external diameter size of cone is equal to the Inner diameter size of cylinder sleeve, and microcephaly's internal diameter comes directly towards maximum side slightly larger than machine mouth rear end Width dimensions, terminal pad is linked together with cone microcephaly's outer rim fitting, head terminal pad be located at it is intermediate by stud with It is integrated after nut with the terminal pad of cylinder sleeve front end top, the preceding terminal pad with machine mouth rear end top for three-in-one be connected and fixed, Two big two it is small be placed in the microcephaly Inner of cone respectively up and down for each two pieces of arc line shaped triangles flow distribution plate, be later one A angle, it is preceding be the arrangement of two angles, the centre between preceding two corners is inwardly projecting arc line shaped, the edge between cone and cylinder sleeve It is several pieces of outer faggings in all spaces.

Beneficial effects of the present invention are：First is that since cone and flow distribution plate are located within the cylinder sleeve of lengthening, rear end Major part outer rim is to be close to inboard wall of cylinder liner, has fagging to prop up between the surrounding volume and inboard wall of cylinder liner of major part front outer rim length, Its extruding force is born by cylinder sleeve, therefore head surroundings wall need not be both made to very thick and eliminated back plan terminal pad, Weight considerably reduce about less than the prior art 1/10th, finished product cylinder sleeve lengthen and need not processing, volume cone it is simply easy Row, so that bottom accordingly drops in cost, manufactures and is become different by difficulty；Second is that easy to disassemble and easy to maintenance, i.e. head front plan terminal pad Positioned at intermediate, cylinder sleeve pelvic outlet plane terminal pad be located at back, machine mouth after plane terminal pad to be located at front be three-in-one by means of spiral shell It is fixed that column and nut wear fixed, this saves the terminal pad of one of stud and nut and back-end of machine head and simpler, i.e. connection dress Setting the twice from before changing becomes together, and the cone at terminal pad back position need only be pushed into cylinder sleeve when installing It looses one's grip and overcome former must be buttressed the deficiency that must be pulled tight one or two of nut and can just let go by more people；It is also equipped with convenient for adding internal layer bushing I.e. by cone by inside and outside two-in-one, the superiority such as internal layer bushing and flow distribution plate need only be replaced to a certain extent by wearing in the future.
