Description
Technical field
The present invention relates to stone material cutting equipment technical field, relate in particular to a kind of stone material gang saw mill.
Background technology
The stone material gang saw mill is the special equipment that is used for the waste material of stone material bulk is cut into thin plate.The waste material of stone material bulk is done feed motion by promoting drive unit on the vertical direction; The saw blade that many groups are parallel to each other is housed in the saw frame, and does the reciprocating motion of horizontal direction along the guide rail that is parallel to saw blade; When the waste material of bulk rose continuously, the saw blade in the saw frame was about to the thin plate that the waste material of stone material bulk cuts into specific thickness.Thin plate can obtain the good stone material plate for building of decorative effect after passing through manufacturing procedures such as grinding and cut-out again.
Existing stone material gang saw mill generally only is used to process Mohs' hardness less than stone materials such as 5 ° marble, lime stones, and its saw kerf can be controlled in the 4mm.
At present, be used for the sawing Mohs' hardness and mainly contain three classes greater than the suitability for industrialized production equipment of 5 ° of granites in slab: the first kind is a granite pendulum-type sand saw, it utilizes saw blade and prismatic steel sand that the impact grinding of granite material is realized cutting function, this is the maximum granite in slab cutting technological equipment of the present consumption in the whole world, because pendulum-type sand saw needs the filling steel sand, and the necessary rigidity when keeping saw blade to withstand shocks power, therefore saw blade thickness is greater than 5mm, sawing adds man-hour, with the saw kerf that produces greater than 8mm, cause producing a large amount of waste residues, and consume, needed 72 hours could process one group of building stones under the normal condition than macro-energy, efficient is very low, and its use cost is higher, and the sawing cost is about 40 yuan/square metre, and it is in Europe, areas such as America have been limited to use.The second class process unit is that the steel wire rope string bead saw that uses is recommended by developed country such as America and Europe in recent years, promptly on annular wire rope, fix a certain amount of diamond cylinder cutter, utilize the rotation of steel wire rope to come stone material is cut, owing to used very sharp diamond cutter, this technological equipment has simple in structure, the advantage that cutting efficiency is high, but owing to be subjected to the restriction of steel wire rope intensity, the diamond bead minimum diameter can only be accomplished 7.2mm, and during the sawing stone material, saw kerf is still about 8mm, so still there is the energy consumption height, the defective that the waste sludge discharge amount is big, and its use cost is higher, and general processing cost is about 50 yuan/square metre.The 3rd kind equipment is the sawing device of cylinder blade, it adopts the major diameter diamond disc of rotation at a high speed to come building stones are cut, owing to be subjected to the restriction of saw blade diameter, when using maximum gauge as the saw blade of 3000mm, also can only the working width size less than the sheet material of 1200mm, and plate surface is second-rate, has the problem of saw kerf greater than 8mm too.
Therefore if utilize the stone material gang saw mill to process granite in slab, therefore its saw kerf must significantly cut down the consumption of energy less than 4mm, reduces waste sludge discharge, increases the effect of volume recovery.But, adopt the stone material gang saw mill to come the cutting granite material to have following two problems: the first, the ton surplus in the of ten that weighs usually of the saw frame in the stone material gang saw mill as shown in Figure 1 and Figure 2, is undertaken hinged by slide block 140 between the connecting rod of saw frame 202 and toggle.Saw frame 202 when reciprocating, will produce maximum acceleration and impulsive force with toggle in the moment of commutation.When saw frame 202 speed reached the excircle linear velocity of flywheel 102, its kinetic energy maximum and acceleration minimum, impulsive force were also minimum; When saw frame 202 ran to left and right limit position, speed was 0, and acceleration equals the angular acceleration of flywheel 102, and this moment, the acceleration of saw frame 202 was also maximum, and it can produce huge impact power to connecting rod 103.So the raising of flywheel 102 rotating speeds has been subjected to the restriction of the maximum impact force that toggle can bear.Flywheel 102 rotating speeds of prior art can only reach between 80-90 rev/min mostly, have therefore limited the lifting of stone material gang saw mill cutting efficient.Second, as shown in Figure 3, the reciprocating track-type facilities of saw frame of existing stone material gang saw mill mainly adopts the horizontal rectilinear motion mode, comprise two symmetrically arranged horizontal guide rails 2, horizontal guide rail 2 is provided with horizontal support face 3, corresponding slidable fit has the upper end of 4, two guide runners 4 of guide runner to be connected with same saw frame 202 on the horizontal support face 3.When adopting the stone material gang saw mill work of said structure, because saw blade 204 running orbits 7 (for straight line) keep plumbness substantially with the direction of feed of rough stone block 6, and whole cutting process keeps this direction not change, saw blade 204 is identical with the waste material of institute's processing stone material 6 length all the time with the contact-making surface of rough stone block 6, because the restriction of saw blade 204 rigidity and intensity, the unit pressure that the saw blade cutting edge roundness is born is limited, rough stone block 6 feed speeds can not effectively improve, and have influenced the cutting efficiency of stone material gang saw mill; Because the cutter contact-making surface is longer, and the cooling water inlet is limited, and saw blade 204 operating frictional heatings are bigger, invalid energy consumption is higher, also is unfavorable for energy-conservation simultaneously.
Summary of the invention
The invention provides a kind of stone material gang saw mill, when commutating in order to the saw frame that solves existing stone material gang saw mill connecting rod is impacted greatly, the flywheel rotating speed is limited, and then has limited the problem of the lifting of stone material gang saw mill cutting efficient.
The present invention adopts following technical scheme: a kind of stone material gang saw mill, comprise saw frame swing guider and toggle, and be connected with saw frame on the described saw frame swing guider, described toggle and described saw frame are in transmission connection with elastic connection structure.
