A kind of forming machine
Technical field
The present invention relates to engineering machinery field, particularly a kind of material forming machinery.
Background technology
The express material of powdery is mainly become round shape or lump material by forming machine, and its application widely, as briquetting manufacture field, also in dynamic value thing field of feed processing, can also comprise garbage-molding manufacture field.
At present, forming machine is divided into ring die forming machine peace panel moulding apparatus, and ring die forming machine peace panel moulding apparatus is all adopt principle of extrusion moulding, and only have shaping moudle structure different, the shaping mould of ring die forming machine is ring-type, and the shaping mould of flat-plate molded machine is tabular.The principle that ring die forming machine adopts be by the pressure roller of the inside and the extruding of external rings mould the materials such as rubbish is extruded from discharge opening.Pressure roller outer surface is smooth surface completely, and be therefore be that the efficiency of the discharge opening of external rings mould is low by rolling extrusion completely, friction loss is large, and power consumption is large.And understand some material cannot be extruded, remain in external rings mold cavity.
Summary of the invention
In view of this, the present invention proposes a kind of forming machine, to solve the problem of forming machine processing and forming efficiency.
On the one hand, the invention provides a kind of forming machine, comprise shaping mould and pressure roller, also comprise two pieces of scrapers, shaping mould is provided with discharge opening, pressure roller is provided with punch, punch coordinates with discharge opening; Two pieces of scrapers lay respectively on shaping mould two side external surface; One piece of scraper is downward-sloping, and another block scraper is inclined upwardly; Shaping mould is loop configuration, and shaping mould comprises internal mold and external mold, and internal mold is nested in external mold; Internal mold and external mold removably connect; Punch is bolted on pressure roller outer surface.
Further, discharge opening comprises circular hole and taper hole, and circular hole is opened on external mold, and taper hole is opened on internal mold, and punch coordinates with taper hole.
Further, discharge opening is evenly arranged on shaping mould by rows, and punch is evenly arranged on the outer surface of pressure roller by rows.
Further, pressure roller comprises two, and two pressure rollers are arranged symmetrically with relative to the center line of shaping mould.
Further, also comprise base, frame, motor, feed arrangement, drawing mechanism, motor is arranged on base, feed arrangement and drawing mechanism and pressure roller and shaping mould are arranged in frame, motor rotates for driving pressure roller, charging aperture on feed arrangement communicates with shaping mould inner chamber, and the outlet on drawing mechanism communicates with the discharge opening on shaping mould.
A kind of forming machine provided by the invention, pressure roller is provided with punch, shaping mould is provided with discharge opening, punch coordinates with discharge opening, engage the same like internal gear with external gear, pressure roller is rotated by motor, and the punch on pressure roller is driven into pattern and rotates in the opposite direction, and between pressure roller and shaping mould, friction loss is little, power consumption is little, from big to small, material is extruded out in gap between punch and discharge opening, and forming machine operating efficiency is high.
In addition, shaping mould adopts external mold and internal model structure, and external mold and internal mold adopt and removably connect, and when after internal mold wearing and tearing, can change.Also be bolted between punch and pressure roller, when after punch wearing and tearing, can change.Thus make forming machine maintenance cost low, high life.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of forming machine comprises base 1, frame 3, motor 2, feed arrangement 5, drawing mechanism 7, shaping mould 4, pressure roller 6, motor 2 is arranged on base 1, feed arrangement 5 and drawing mechanism 7 and pressure roller 6 and shaping mould 4 are arranged in frame 3, shaping mould 4 and pressure roller 6 are rotatably connected with frame 3, motor 2 rotates for driving pressure roller 6, pressure roller 6 drives shaping mould 4 to rotate, charging aperture on feed arrangement 5 communicates with shaping mould 4 inner chamber, and the outlet on drawing mechanism 7 communicates with the discharge opening on shaping mould 4.
As shown in Figures 2 and 3, shaping mould 4 is provided with discharge opening, discharge opening is evenly arranged on shaping mould 4 by rows.
Pressure roller 6 comprises two, and two pressure rollers 6 are arranged symmetrically with relative to the center line of shaping mould 4.Pressure roller 6 is provided with punch 60, punch 60 is bolted on pressure roller 6 outer surface, and punch 60 coordinates with discharge opening.Punch 60 is evenly arranged on the outer surface of pressure roller 6 by rows.Certainly, punch 60 also can adopt screw or interference fit or be fixed on pressure roller 6 outer surface.
Shaping mould 4 is loop configuration, and shaping mould 4 comprises internal mold 40 and external mold 41, and internal mold 40 is nested in external mold 41, and internal mold 40 and external mold 41 are bolted.Discharge opening comprises circular hole 410 and taper hole 400, and circular hole 410 is opened on external mold 41, and taper hole 400 is opened on internal mold 40, and punch 60 coordinates with taper hole 400.
It should be noted that, internal mold 40 and external mold 41 also can adopt screw, interference fit, and dismountable mode such as clamping connects, no matter it is all equivalent for adopting what mode to realize connecting.Discharge opening can the shape of providing holes as required, and as circular hole 410 changes square hole or elliptical aperture or ball into, taper hole 400 changes spherical or square hole or elliptical aperture into, no matter adopt what shape to be all fine, is also all equivalent.
In addition, the outer surface of external mold 41 is also provided with two pieces of scrapers, 8, two pieces of scrapers 8 respectively with two side external surfaces of external mold 41 against.Scraper 8 is for cutting off the material squeezed out.One piece of scraper 8 is downward-sloping, and another block scraper 8 is inclined upwardly.
Forming machine operation principle of the present invention is as follows:
Material enters the inner chamber of internal mold 40 from feed arrangement 5, and motor 2 is rotated by belt drives pressure roller 6, and the punch 60 on pressure roller 6 engages with the taper hole 400 on internal mold 40, drives internal mold 40 and external mold 41 to rotate.The gap that punch 60 engages with taper hole 400 from large to small, thus makes material be extruded out from taper hole 400 and circular hole 410, and the scraper 8 be positioned on external mold 41 outer surface cuts off, and columniform material is discharged from drawing mechanism 7.
Forming machine of the present invention adopts similar internal gear and the external gear theory of engagement, and make friction loss between pressure roller 6 and shaping mould 4 little, power consumption is little, and forming machine operating efficiency is high.
As shown in Figure 4, the forming machine of the second embodiment of the present invention is different from the forming machine of Fig. 1 to be, shaping mould 9 is flat structure, shaping mould 9 is provided with discharge opening 90, and pressure roller 10 is conical structure, pressure roller 10 is provided with punch 100.Punch 100 engages with discharge opening 90, can implement object of the present invention equally.Preferably, shaping mould 9 one-tenth disc, pressure roller 10 is set to two, and is arranged symmetrically with relative to the center line of shaping mould 9, and for the pressure roller 10 of pyramidal structure, the small end of pressure roller 10 is near the center of shaping mould 9.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
