Description

Technical Field:

[0001] The present invention belongs to the field of stone processing machinery, and particularly relates to a curbstone head-cutting and segmenting device, which can particularly complete the segmenting and head-cutting operations on a block of stone at one time. Background Art:

[0002] There are various existing stone processing machines. Particularly common is the gantry sawing machine, which can not only complete slicing by using the crossbeam track but also achieve a feeding action by using the longitudinal track, or vice versa. Coupled with the lifting function of the sawing machine itself, it forms a three-axis processing ability, basically meeting various processing requirements. However, when using a multi-blade sawing machine to achieve the segmenting operation, due to the constraint of the distance between the two saw blades, the specifications of the stone blocks are limited, and simple use is obviously inefficient.

[0003] In order to meet the processing of various specifications of stone materials, in addition to the sawing machine as the main body, other special equipment such as angle cutting machines and edge grinding machines are also required. They are strung into an organic whole through a conveyor belt and a flipping mechanism to achieve automated operation; however, corresponding tooling fixtures need to be designed for different products to meet the needs of automated control. Summary of the Invention:

[0004] The purpose of the present invention is to design a curbstone head-cutting and segmenting device that combines several gantry sawing machines with a workbench that integrates conveying, aligning, and clamping.

[0005] The technical solution of the present invention is realized as follows: A curbstone head-cutting and segmenting device includes a gantry, sawing machines, and a workbench, and is characterized in that:

Adjacent rollers are connected by a chain drive, and the end roller is connected to the motor by a drive; a plurality of said sleepers are interspersed between the rollers and locked on a lifting frame, and a lifting oil cylinder is arranged between the lifting frame and the frame, which can drive the sleepers to rise above the rollers or descend below the roller surfaces; the straightedge fixture includes a cantilever straightedge and a clamping assembly, and they are respectively fixed on the frames at both ends of the rollers; the clamping assembly consists of a mounting seat, a clamping oil cylinder and a stop block; the mounting seat is locked on the frame, the cylinder body of the clamping oil cylinder is locked on the mounting seat, the stop block is fixed at the end of the piston rod and points to the side of the cantilever straightedge, and can form a clamping state with the cantilever straightedge; there are two or more said straightedge fixtures, which are distributed along the direction of a row of rollers, and the connection line between the cantilever straightedge and the stop block is higher than the height of the highest rising sleeper.

[0009] The second roller from both ends inward of the workbench is replaced by a telescopic roller assembly, which includes a slideway seat, a telescopic oil cylinder and a roller shaft; the slideway seat is fixed on the frame at the end of the roller, the cylinder body of the telescopic oil cylinder is locked at the far end of the slideway seat, and the end of the piston rod pulls a roller car, which can travel on the slideway seat under the traction of the piston rod; the roller car positions the above-mentioned roller shaft through bearings, and the suspended end of the extended roller shaft can be placed on a support seat arranged on the frame to form a load-bearing structure.

[0010] A tapered hole is machined at the end of the suspended end of the roller shaft in the telescopic roller assembly, and the support seat is correspondingly machined into a tapered protrusion, and alignment is formed by means of the tapered protrusion and the tapered hole during lapping.

[0011] A rubber block is arranged on the end face of the cantilever straightedge in the straightedge fixture, and the surfaces of the rubber blocks of a plurality of cantilever straightedges are on the same plane.

[0012] A pair of translation beams are arranged on the two feed beams of the gantry, and more than two sawing machines are arranged on each translation beam; on the corresponding sides of the rectangular frame in the workbench, rollers, sleepers and straightedge fixtures are symmetrically arranged to form two parallel stone material conveyances and alignment clamps.

[0035] Refer to Figure 1 , Figure 2 and Figure 3The device for cutting curbstones into segments comprises three major components: a gantry 1, a saw machine 2 and a workbench 3, and can provide coordinated operation.

[0036] The gantry 1 includes a feed beam 11 and a translation beam 12; the feed beam 11 is provided with a feed track 111, a feed slider 112 and a feed rack 113; the translation beam 12 is also provided with a translation track 121, a translation slider 122 and a translation rack 123. The feed beam 11 is perpendicular to the material travel direction, and the translation beam 12 is placed on the two feed beams 11 in parallel with the material travel direction, more specifically, placed on the feed slider 112 of the feed track 111, and driven by the feed power 124 on the horizontal translation beam to realize the feeding action of the translation beam 12. The feed power 124 includes a motor, a gearbox and a feed gear 1241 on the output shaft, and the feed gear 1241 is meshed with the feed rack 113 on the feed beam 11, and the motor drives the translation beam 12 to reciprocate along the feed track 111 on the feed beam 11 to realize the feeding operation, which are all conventional technologies.

[0037] The saw machine 2 includes a cutting motor 21, an output shaft 22 and a saw blade 23. The motor 21 is transmission-connected to the output shaft 22, and a gearbox can be added between the two as needed. The selected saw machine 2 is a double-blade saw machine, and its two saw blades 23 are separately locked on both ends of the output shaft 22, and the spacing can be adjusted to cut stones of different lengths.

[0038] Two or more saw machines 2 with lifting function are fixed on the translation slider 122 of the translation track 121, and can adjust the distance between the saw machines, that is, through the translation force 24 carried by the saw machine; the translation force 24 is also a short name, which also includes a motor, a gearbox and a translation gear 241 on the output shaft. With the help of the translation gear 241 engaging with the translation rack 123, the distance between the two or more saw machines 2 can be adjusted on the translation beam 12.

[0039] Furthermore, the plurality of sawing machines 2 with lifting function are also provided with gear encoding components 9 in both lifting and horizontal directions, including an encoder 91 fixed on the lifting frame or the moving pulley, and an encoding rack 92 fixed on the lifting frame or the translation beam. The encoder is used to accurately determine the position of the sawing machine, which is convenient for automatic adjustment, such as Figure 3 .

[0040] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6, the workbench 3 provides stone material conveyance, as well as stone material alignment and clamping actions, and it includes a frame 4, rollers 5, sleepers 6 and a straightedge clamp 7; the frame 4 is in a rectangular structure to form a main body support function. At one end of a plurality of rollers 5, double sprockets 51 are fixed, and they are arranged side by side on the frame 4 along the direction of material travel. Adjacent rollers 5 are connected by a chain drive (not shown in the figure), and one of the end rollers 5 is connected to a motor 52 for power access. The rollers roll in the same direction through the double sprockets 51 to meet the need of conveying stone materials.

[0041] A plurality of sleepers 6 are interspersed between the rollers 5 and locked on a lifting frame 61. A lifting oil cylinder 62 is arranged between the lifting frame 61 and the frame 4, which can drive the sleepers 6 to rise above the rollers 5 or descend below the roller surface; when rising, it can lift the stone materials conveyed by the rollers 5 and provide a downward space for the saw blade cutting; when descending, it can place the cut stone materials on the rollers 5 again, and then the rollers 5 convey them out.

[0042] The straightedge clamp 7 includes a cantilever straightedge 71 and a clamping assembly 72, and they are respectively fixed on the frame 4 at both ends of the roller 5; the clamping assembly 72 is composed of a mounting seat 721, a clamping oil cylinder 722 and a stop block 723; the mounting seat 721 is locked on the frame 4, the cylinder body of the clamping oil cylinder 722 is locked on the mounting seat 721, the stop block 723 is fixed at the end of the piston rod and points to the side of the cantilever straightedge 71, and it can form a clamping state with the cantilever straightedge 71; that is, when the roller 5 conveys the stone materials in place and they are lifted by the sleepers 6, the clamping oil cylinder 722 is started. Firstly, it pushes the stone materials towards the side of the cantilever straightedge 71 to align the edges of the stone materials; secondly, after alignment, the clamping oil cylinder 722 continues to maintain the oil pressure, that is, the clamping state is achieved to ensure that the stone materials do not deviate during saw blade cutting.

[0043] There are two or more straightedge clamps 7, and they are distributed along the direction of a row of rollers 5. The connection line between the cantilever straightedge 71 and the stop block 723 is higher than the height of the highest rising sleepers 6. And a rubber block 711 is arranged on the end face of the cantilever straightedge 71, and the surfaces of the rubber blocks 711 of multiple cantilever straightedges are on the same plane to play a role in anti-impact.

[0044] Furthermore, the second roller from both ends inward of the workbench 3 is replaced by a telescopic roller assembly 8, and the telescopic roller assembly 8 includes a slideway seat 81, a telescopic oil cylinder 82 and a roller shaft 83; the slideway seat 81 is fixed on the frame 4 at the end of the roller, the cylinder body of the telescopic oil cylinder 82 is locked at the far end of the slideway seat 81, and the end of the piston rod pulls a roller cart 84, and the roller cart 84 can move on the slideway seat 81 under the traction of the piston rod;

[0045] The roller cart 84 positions the upper roller shaft 83 through bearings, enabling the roller shaft 83 to roll freely; the suspended end of the extended roller shaft 83 can rest on the support seat 85 provided on the frame 4 to form a load-bearing structure. More specifically, a tapered hole 831 is machined at the end of the suspended end of the roller shaft 83, and the support seat 85 is correspondingly machined into a tapered protrusion 851. When lapping, alignment is formed by means of the tapered protrusion 851 and the tapered hole 831, that is, automatic centering is formed. Of course, the tapered protrusion and the tapered hole can also be interchangeably arranged.

[0046] In summary, in order to improve efficiency, a pair of translation beams 12 are provided on the two feed beams 11 of the gantry 1, and more than two sawing machines 2 are provided on each translation beam 12. In the legend, three sawing machines 2 are provided respectively; on the corresponding sides of the rectangular frame 4 in the workbench 3, roller cylinders 5, sleepers 6 and ruler jigs 7 are symmetrically arranged to form two parallel stone material conveyances and alignment clamps, which also improves the space utilization rate of the site.
