Abstract

The utility model relates to a sawing device for the semifinished marble plate, belonging to the processing device of stone. A hinged connection structure is adopted between the end part of a frame saw blade and a connector. When the stone is sawed to a certain height along the height direction, an electrical machine is used for directly driving a horizontal disc saw blade to cut and separate the semifinished plate into pieces. The frame saw can be continuously used for sawing the pieces along the height direction. The device is suitable for processing the semifinished plate with the thickness of more than 14 mm. The minimum thickness is small; the damage rate is low. The utility model can be suitable for the reconstruction of the existing frame saw and the development of a novel frame saw.

Description

Sawing arrangement for the semifinished marble plate

The utility model relates to the used device of processing of a kind of stone or similar rock material, particularly a kind of saw cutting device of thin marble hair plates.

Current people use the reciprocal sawing of buck saw to go out the hair plates of marble slabs, and the thinnest width that can only process is 20 to 22 millimeters a marble hair plates.Technology now is after earlier building stones sheet material being become hair plates along the whole sawings of short transverse, by manually hair plates being separated recovery one by one.Each buck saw saw blade adopts T type groove syndeton along its width, and (each buck saw saw blade end is T-shaped, be equipped with corresponding connector) with their stretch-draw pretensions on saw frame, spacing between two buck saw saw blades is owing to include the width of corresponding two connectors, so can't further reduce again; When processing the thin hair plates of 20 millimeter in addition, owing to greatly reduce during the relative slab of intensity, manually hair plates is separated one by one that breakage rate greatly increases when reclaiming, so can not satisfy the needs of domestic and international market far away.

The purpose of this utility model is the deficiency that can't process thin hair plates at above prior art, at first improves the stretch-draw and the fixing structure of each saw blade end of buck saw, makes that spacing can greatly reduce than prior art between each saw blade; Increase by one in addition and laterally reclaim shut-off mechanism, when buck saw to building stones along the short transverse sawing to certain depth H after, laterally reclaiming shut-off mechanism with this is that the hair plates of H cuts off from building stones one by one and separates with height, and then continues along the short transverse sawing.

Task of the present utility model is finished as follows: in order to reduce spacing between each saw blade of buck saw, each saw blade end thickness can reduce greatly, each saw blade connector carried out in each saw blade end portion thickness size range with only being connected of saw blade end, so structure that adopts radial type to connect, embed cylindrical articulated body and I-shaped connector successively in each saw blade end, I-shaped connector by pretension cushion block stretch-draw pretension on the saw frame crossbeam.In order to make between each saw blade spacing adjustable, used band structure T-slot and interchangeable parallel block.According to technological requirement, after buck saw arrives certain depth H to building stones along the short transverse sawing, adjust the height and the front and back position of the centrifugal disc saw blade of a motor direct-drive, piecewise the transversely cutting hair plates in addition.Also be about to full-height sawing recovery and change the billet-sawn recovery into.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is each saw blade end stretch-draw of the utility model buck saw and fixing structure chart, and wherein Fig. 1 a is vertical partial sectional view of Fig. 1 b.

Fig. 2 is the horizontal recovery shut-off mechanism that is loaded on the dolly of the present utility model.

With reference to Fig. 1, the circular hole of a band opening is arranged in the end (2) of each saw blade of buck saw (1), wherein embed cylindrical articulated body (7), I-shaped connector (6) successively.Pretension cushion block (5) with end (2) stretch-draw of each saw blade of buck saw (1) and pretension on saw frame crossbeam (4).Pretension cushion block (5) also can be the sensor that can survey the stretch-draw pretightning force.When each saw blade of buck saw (1) is installed, the interchangeable parallel block of choosing (8) is inserted in the T-slot of connecting plate (9), place between the end (2) of two buck saw saw blades (1), guarantee that the hair plates under the saw satisfies required thickness.After all buck saw saw blades (1) were adjusted, available voussoir compressed (10), and presses pressing plate in the above (3), in case play during each buck saw saw blade (1) work.

The matching used whole horizontal recovery shut-off mechanism of the utility model is installed on the dolly (15) of dress building stones (16) among Fig. 2.When needing the good hair plates of amputating saw, shake down handwheel (301), make down-feed screw (304) rotation synchronously by down synchronous belt (303), conical gear case (302) and major axis (306), make that the shut-off mechanism on the slide block (206) rises to desired height along column (305) about being installed in.Then, shake handwheel (201), by last synchronous belt (204), screw mandrel (202) before and after driving, slide block (205) drives the shut-off mechanism head and moves to a certain position along front and back guide rail (203) before and after making, and guarantees that the shut-off mechanism head just in time cuts off a hair plates at every turn.At last, starter motor (102), it directly rotates centrifugal disc saw blade (101); Restart the motor (103) that has reduction box, the shut-off mechanism head is advanced along cross slide way (104), so the centrifugal disc saw blade (101) that rotates is finished the transversely cutting work of a hair plates at last.During actual transversely cutting, should on the appropriate location of horizontal joint-cutting, put into some pads, in case kill centrifugal disc saw blade (101) during the hair plates fracture.

When whole horizontal recovery shut-off mechanism is not worked, should be parked in the shut-off mechanism head on following, the rightest position of dolly (15), in order to avoid disturb the operate as normal of buck saw.

The utility model has the advantages that: the thinnest hair plates that can process 14 millimeters thick, stone material recovery rate height is suitable for the transformation of existing buck saw and develops novel buck saw.
