Abstract

The utility model discloses a punching forming machine with an external crankshaft. The punching forming machine comprises a machine body and a punching rod, wherein the machine body is provided with a punching chamber, the end part of the punching rod is stretched into the punch chamber, and the punching rod is driven to do a reciprocating motion by virtue of a driving device; the driving device comprises belt wheel sets driven by a power source, the belt wheel sets are integrally connected by virtue of working spindles to do a synchronous motion, and offset shafts are symmetrically arranged on spokes on two outer sides of the belt wheel sets; a horizontal shaft parallel with the working spindles is arranged in the machine body, the middle of the horizontal shaft is in transmission connection with the punching rod, and two end parts of the horizontal shaft are extended out of the machine body and are respectively in transmission connection with the offset shafts by virtue of working rods on two sides of the horizontal shaft. The punching forming machine has the advantages that the external combined crankshaft is formed by the working spindles, the belt wheel sets and the offset shafts on the spokes on two outer sides of the belt wheel sets, so that the eccentric distance of the external combined crankshaft is effectively increased, and the punching stroke can be increased by three times when the power of a driving motor is unchanged; the integral device is simple in structure and is convenient to manufacture, the working efficiency can be substantially increased, and the energy-saving effect is remarkable.

Description

Bent axle external impact molding machine

Technical field

The utility model relates to stamping machine, especially relates to a kind of bent axle external impact molding machine.

Background technology

Biological particles is used for the daily life of industrial and agricultural production or family at the alternative coal in a lot of fields, oil, gas, have the laudatory title of artificial coal, as be usually used in the fields such as generating, boiler, metal heat treatmet, hot-blast stove, drying materials, diet.Primary raw material is many to be made up of sawdust, leaf, stalk, cavings, rice husk, vinasse the like waste, the pollutant discharging when burning is few, and in manufacture process, do not need to add any other adhesive yet, the policy that meets national environmental protection and encourage the renewable sources of energy effectively to utilize, the new forms of energy project of falling over each other research and development both at home and abroad, for sustainable development with improve environment and brought Gospel.

Biomass combustion particle impact molding machine is exactly that generally discarded pollution-free or non-staining inflammable substance stamped is become to flammable high density granular.Because adopt high speed, impacting with high pressure moulding, so molding materials density large (approximately 1.3 tons/cubic metre), approach the density that even exceedes coal, particle is obviously better than the shaped granule that adopts other moulding process equipment to prepare resistance to burning time, and it is simple to have mould manufacture, it is convenient to safeguard, change, long service life and with low cost, and to advantages such as feed particles fineness and humidity before moulding are insensitive.

The impact molding machine that tradition is used generally adopts built-in bent axle (seeing accompanying drawing 1), motor 1 drives by small pulley 2, V-belt 3, two large belt wheels 4 bent axle 6 that is built in body 5 inside, and by its drive be positioned at the connecting rod 7 of body and active pin shaft 8 and punch rod 9 by the material in punching press chamber 10 by 11 extrusion modlings of discharging mould.Because the eccentric throw of bent axle 6 is subject to structure and limits of fabrication techniques, so stroke is little, while causing work, yield poorly, power consumption is high; If increase the eccentric throw of bent axle, not only make whole equipment heaviness huge, also can make Crankshaft Machining more complicated, the requirement to machining accuracy and the lubricating condition requirement to bent axle also can be higher; Impact while simultaneously work under continuous heavy load makes bent axle bear huge impulsive force at Maximum turning radius place, causes serious wear, and maintenance cost is high and technical difficulty is large.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, the easily manufactured and significant bent axle external of energy-saving effect impact molding machine.

For achieving the above object, the utility model can be taked following technical proposals:

Bent axle external impact molding machine described in the utility model, comprise with the body in punching press chamber and end and extend in punching press chamber and drive reciprocating punch rod by drive unit, described drive unit comprises being combined as a whole and done the belt pulley set being synchronized with the movement by working-spindle of being driven by power source, on two outside spokes of described belt pulley set, is symmetrically arranged with bias axis; In described body, be provided with the transverse axis being parallel to each other with described working-spindle, the middle part of described transverse axis and described punch rod driving coupling, its both ends extend outside described body work connecting rod by both sides respectively with described bias axis driving coupling.

The utility model has the advantage of simple in structurely, easily manufactured, can increase substantially operating efficiency and energy-saving effect is remarkable.Concrete advantage may be embodied in: 1) formed together external vuilt-up crankshaft by the bias axis on working-spindle, belt pulley set and two outside spokes, because the setting position of bias axis on spoke can be adjusted, can effectively increase the eccentric throw of this external vuilt-up crankshaft, not only intensity is greater than built-in bent axle, and each modular construction is simple, processing and manufacturing cost and maintenance cost are all lower; 2) in the situation that drive motors power is constant, punching stroke can increase by three times, therefore can appropriateness reduce the rotating speed of working-spindle, improves its lubricating status; Owing to having improved drawing velocity and the stamping press of impact molding machine, can improve output 30%, shaped granule density has improved 20%, can reduce by 20% to the humidity requirement of raw material simultaneously, and energy-saving effect is remarkable.

Detailed description of the invention

As shown in Figure 2, bent axle external impact molding machine described in the utility model, comprise with the body 2 in punching press chamber 1 and end and extend in punching press chamber 1 and drive reciprocating punch rod 3 by drive unit, drive unit comprises that the working-spindle 4 that passes through being driven by power source combines as a whole and does the belt pulley set 5 being synchronized with the movement, belt pulley set 5 is in transmission connection by V-belt 6 and the small belt pulley 8 on power motor 7 output shafts, on two outside spokes of belt pulley set 5, is symmetrically arranged with bias axis 9; In body 2, be provided with the transverse axis 10 being parallel to each other with working-spindle 4, the middle part of this transverse axis 10 and punch rod 3 driving coupling, its both ends extend outside body 2 work connecting rod 11 by both sides respectively with bias axis 9 driving coupling; On the sidewall in punching press chamber 1, offer charging aperture, this charging aperture is connected mutually with the discharging opening of screw feeder 12, is provided with discharging mould 13 in the exit in punching press chamber 1.

When work, power motor 7 drives the vuilt-up crankshaft being made up of belt pulley set 5, working-spindle 4 and bias axis 9 by small belt pulley 8, V-belt 6, and driving punch rod 3 to move reciprocatingly by this vuilt-up crankshaft by work connecting rod 11 and transverse axis 10, the material that screw feeder 12 is fed in punching press chamber 1 is pressed into extrusion modling in discharging mould 13.Because the distance between bias axis 9 axle center and working-spindle 4 axle center can be adjusted (eccentric throw that is vuilt-up crankshaft can increase as required) as required, improve the punching stroke of stamping machine, not only save the energy but also improved output.
