Powerful vertical slitting machine

Technical field

The present invention relates to a kind of accessory machinery that brick and tile enterprise is supporting with main frame aborning, be more definitely more particularly used to cut into continuously billet on-stream extruded for main frame a kind of cutting machine of monolithic adobe or unbaked tile.

Background technology

In cutting, current most of brick fields adopt hands merit and push-and-pull steel wire rack cutting back and forth or swinging steel wire automatic slicing, the former institute's section is oblique line, the latter institute section is arc, and the six of standard brick billet faces must be all plane, institute's pinch-off bar face is that two big faces therein, six faces more should be concordant, therefore often cuts a billet and base head more or less can be caused to waste, be generally one or two adobe.

Hands merit cutting is to utilize manpower to win over moving towards steel wire frame at a right angle with billet and push through, often push or pull on and once can cut off a billet, owing to billet is continuously to extrude from the machine mouth of main frame, and hands merit cannot realize Tong Bu with billet in push-and-pull, namely billet is ceaselessly moved along, in the process pushed or pulled on, steel wire cuts to the left or to the right, making to cause steel wire, to initially enter the billet of billet side short, the billet going out side eventually is long, speed according to billet walking speed also should be the inclined-plane of certain angle mutually with its facet of length of clipping time, therefore want to become right angle section with billet trend (length) can not realize.

Utilize its acting principle of revolution steel wire automatic slicing as shown in Figure l, the thrust that billet is formed extruding from machine mouth 10 is relied on to be affixed produced friction with each roll bar on billet support 9, the active roll bar l promoting one of them diameter maximum rotates, it is arranged on and also does the rotation of equidirectional with the sprocket wheel 2 on the same axle of drive roll, namely the roll bar that billet is following its top edge while billet moves forward is followed billet under the promotion of billet and is rotated forward with equal speed (non-slip when), with movable sprocket 2 and chain 12 and be arranged on the sprocket wheel 3 on another root axle and gear 4 operates in rotation, driven dumb bell shaft gear 6 to do opposite direction again by gear 4 to rotate, the sprocket wheel 7 cut on shelf 9 is driven to operate with the sprocket wheel 5 on gear 6 same axis in dynamic turning, sprocket wheel 7 drive is cut bow 8 and is done gyration, two cut bow 8 tops between be provided with steel wire 11 play a part cut off billet, drive roll 1 often rotate a circle its steel wire cut off billet once namely cut out a billet 13, the steel wire quickly being served brick cutting machine by manpower after billet is cut-off and be easy to cut on bow in revolution up time be unlikely and stopped by billet, the length of billet is essentially equal with the girth (non-slip when) of drive roll l. so when billet borrows frictional force to promote drive roll 1 to rotate in reach, drive is cut bow rotation and is done work, and thus cuts off the billet of an another bar again and again.

This cutting cutter has saving manpower, billet length stabilisation, easy to operate and save the advantage such as power, shortcoming is that cutting section is arcuation but not concordant, its reason is to cut bow to drive cutting steel wire its route in rotation to be a circle, thus the useless base in two ends is many and cause waste in next procedure and pinch-off process; Additionally, revolution steel wire is close to produced frictional force with its base drive roll 1 from billet with the operation power cutting bow in reach, owing to its frictional force is very limited, when billet moisture content less and billet is harder and produces high hole rate and during its billet lighter in weight of non-bearing hollw article, when cutting bow running resistance and being bigger, cutting is easy for cause transversely deforming to destroy the cross dimensions of wet base, even can't cut the phenomenon of (cannot cut) and occur.

Only manage new-type cutting cutter and possess that cutting planes is neat and dynamics is powerful, but must obtain supporting power such as pneumatic cutting machine can't do without air pump device because structure is numerous and diverse the more high deficiency of manufacturing cost.

Summary of the invention
