Description

Technical Field

[0001] The invention relates to the field of nonferrous metal sawing machine equipment, and in particular to a double-saw table turnover mechanism of a novel sawing machine. Background Art

[0002] Precision saws are key equipment in the production of aluminum alloy sheets. During sawing, the sheets are typically placed on a sawing table, and the saw moves horizontally and vertically to cut the sheets. For environmental and logistical reasons, the sawing area and loading and unloading areas of the saw are separated. During sawing, the sawing table requires manual loading from the loading and unloading area, then moves to the sawing area for sawing, and finally returns to the loading and unloading area for manual unloading. Because the sawing of the sheets and manual loading and unloading occur in series, and the manual unloading of scrap and finished products, table cleaning, and loading of boards for cutting are time-consuming, manual loading and unloading accounts for approximately 30% of the entire sawing process.

[0003] Some foreign manufacturers have adopted a solution where two sawing tables are arranged side by side in the sawing area. This solution can meet the needs of parallel sawing and manual loading and unloading, greatly improving the efficiency of the saw machine. However, the side-by-side arrangement requires doubling the width of the saw machine, significantly increasing the complexity of the saw machine and the area it occupies. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a new double sawing table turnover mechanism for a sawing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A new type of double sawing table turnover mechanism for a sawing machine includes a sawing table I, a sawing table II, a wire rope tensioning device installed on a foundation, a transverse trolley I, a transverse trolley II and a transverse drive device, wherein the wire rope tensioning device is connected to the wire rope, and the wire rope is connected to the traction trolley. The traction trolley can run along the sawing table track installed on the foundation under the traction of the wire rope, and the traction trolley can be connected to the sawing table I or the sawing table II, and the transverse drive device is connected to the driving sprocket, and a transverse chain is provided on the driving sprocket. The transverse trolley I and the transverse trolley II are both fixedly connected to the transverse chain, and each transverse trolley is installed with two oil cylinders, which can lift the sawing table I or the sawing table II from the sawing table track.

[0007] Furthermore, an upward handle is designed at the right end of the traction trolley, and the upward handle can be engaged with the downward handle on the left side of the sawing table I or the sawing table II. When the handle of the traction trolley is engaged with the handle of the sawing table I or the sawing table II, the traction trolley can drag the sawing table I or the sawing table II to move on the sawing table track.

[0008] Furthermore, there is a discontinuity in the middle of the sawing table track, and the discontinuity is used to avoid the oil cylinders on the transverse trolley I and the transverse trolley II.

[0009] Furthermore, the sawing table I is provided with several groups of support wheels, each group of support wheels is two, and the sawing table II is provided with several groups of support wheels, each group of support wheels is two, and both the sawing table I and the sawing table II can run on discontinuous sawing table tracks.

[0010] Furthermore, the transverse driving device includes a motor reducer and a coupling.

[0011] Furthermore, the steel wire rope is connected to a steel wire rope driving device, and the structure of the steel wire rope driving device is that a motor reducer drives a steel wire rope drum.

[0012] Furthermore, the wire rope tensioning device pulls the pulley through the oil cylinder to tighten the wire rope.

[0013] Furthermore, the number of the transverse trolleys can be expanded to multiple according to the length of the sawing table.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The double sawing table turnover mechanism of the new sawing machine of the present invention is mainly used in sawing machines, especially precision sawing machines for aluminum plates. A total of two sawing tables are provided. One sawing table enters the sawing area at a time, which can meet the requirement that the precision sawing table can operate in the sawing area and the loading and unloading area. At the same time, through the alternating turnover of the two sawing tables, the sawing process in the sawing area and the loading and unloading process in the loading and unloading area can be carried out simultaneously, saving a lot of auxiliary time and greatly improving the production efficiency of the precision saw.

[0016] (2) The present invention has a compact structure, and a sawing table is arranged in the width direction of the sawing area, which reduces the width direction stroke of the saw machine and can reduce the area occupied by the saw machine;

[0017] (3) The mechanism of the present invention uses a steel wire rope to pull the sawing table, which has a simple structure and strong resistance to aluminum chip pollution; it is particularly suitable for fully automatic CNC sawing of precision sawing machines.

[0028] like Figures 1-2 As shown, a new type of double sawing table turnover mechanism of a sawing machine includes a sawing table I4, a sawing table II11, a wire rope tensioning device 1 installed on the foundation, a transverse trolley I7, a transverse trolley II13 and a transverse driving device 12, wherein the wire rope tensioning device 1 is connected to the wire rope 2, and the wire rope tensioning device 1 pulls the pulley through the oil cylinder to tighten the wire rope 2, the wire rope 2 is connected to the traction trolley 3, and the traction trolley 3 can run along the sawing table track 6 installed on the foundation under the traction of the wire rope 2, the traction trolley 3 is connected to the sawing table I4 or the sawing table II11, the transverse driving device 12 is connected to the driving sprocket 10, and the driving sprocket 10 is provided with a transverse chain 9, the transverse trolley I7 and the transverse trolley II13 They are all fixedly connected to the transverse chain 9. Two oil cylinders are installed on each transverse trolley, which can lift the sawing table I4 or the sawing table II11 from the sawing table track 6 through the oil cylinders.

[0029] An upward handle is designed at the right end of the traction trolley 3, and the upward handle can be engaged with the downward handle on the left side of the sawing table I4 or the sawing table II11. When the handle of the traction trolley is engaged with the handle of the sawing table I or the sawing table II, the traction trolley 3 can drag the sawing table I4 or the sawing table II11 to move on the sawing table track 6.

[0030] There is a discontinuity in the middle of the sawing table track 6, which is used to avoid the oil cylinders on the transverse trolley I7 and the transverse trolley II13; the sawing table I4 is provided with several groups of support wheels, each group of support wheels has two, and the sawing table II11 has the same structure as the sawing table I4, and the sawing table II11 is provided with several groups of support wheels, each group of support wheels has two, and both the sawing table I4 and the sawing table II11 can run on the discontinuous sawing table track 6.

[0031] The transverse driving device 12 includes a motor reducer and a coupling, which can transmit power to the drive sprocket 10 to drive the transverse trolley I7 and the transverse trolley II13 to perform transverse movement.

[0032] The steel wire rope 2 is connected to a steel wire rope driving device 5 , and the structure of the steel wire rope driving device 5 is a motor reducer driving a steel wire rope drum.

[0033] The trolley track 8 is used for the operation of the transverse trolley, and the transverse trolley moves back and forth on the trolley track; the trolley track 8 is installed on the foundation.

[0034] Those skilled in the art will appreciate that the number of the transverse trolleys may be expanded to multiple according to the length of the sawing table.

[0035] The method of using the double sawing table turnover mechanism of the novel sawing machine is as follows:

[0036] After the sawing is completed, the sawing table unloads the material from the sawing area. For example, the unloading station I is unloaded to the upper unloading station:

[0037] Step 1: The wire rope drum in the wire rope drive device 1 rotates clockwise, and the wire rope 2 pulls the traction trolley 3 to the right. Since the handle on the traction trolley 3 and the handle on the sawing table I4 are in a buckled state, the sawing table I4 is pushed to the right by the traction trolley 3 to the position shown in the figure. At this time, the state is as follows: Figures 3-5 As shown;

[0038] Step 2: The oil cylinders on the transverse trolley I7 and the transverse trolley II13 directly below the sawing table I4 rise, lifting the sawing table I4 and separating it from the sawing table roller 6;

[0039] In the third step, the transverse drive device 12 drives the drive sprocket 10 to rotate, and the transverse chain 9 on the drive sprocket 10 transports the transverse trolley I7 and the transverse trolley II13 together with the sawing table I4 supported on them to the upper loading and unloading station;

[0040] Step 4: After reaching the upper loading and unloading station, the status is as follows: Figures 6-7 As shown, the oil cylinders on the transverse trolley I7 and the transverse trolley II13 fall down and lose contact with the sawing table I4. At this time, the sawing table I4 falls on the foundation, and then the sawing table is manually unloaded and loaded.

[0041] After loading is completed, the sawing table enters the sawing area for sawing. Take the sawing table II at the unloading station below entering the sawing area as an example:

[0042] Step 1: The transverse drive device 12 drives the drive sprocket 10 to rotate. The transverse chain 9 on the drive sprocket 10 moves the transverse trolley I7 and the transverse trolley II13 to the position directly below the sawing table II11 at the unloading station.

[0043] Step 2: The oil cylinders on the transverse trolley I7 and the transverse trolley II13 are raised to lift the sawing table II11 off the foundation;

[0044] In the third step, the transverse drive device 12 drives the drive sprocket 10 to rotate, and the transverse chain 9 on the drive sprocket 10 transports the transverse trolley I7 and the transverse trolley II13 together with the sawing table II11 supported thereon to the middle position;

[0045] In the fourth step, the oil cylinders on the transverse trolley I7 and the transverse trolley II13 fall down, and the sawing table II11 falls exactly onto the sawing table roller 6. At the same time, the handle on the left side of the sawing table II11 is buckled with the handle on the traction trolley 3;

[0046] In the fifth step, the wire rope drum in the wire rope drive device 5 rotates counterclockwise, the wire rope 2 moves the traction trolley 3 to the left, and the sawing table II11 is also pulled to the left by the traction trolley 3 to the sawing area and stops, and then the saw machine starts sawing.

[0047] The above only describes the sawing table I4 leaving the sawing area and the sawing table II11 entering the sawing area. The action process of the sawing table II11 leaving the sawing area is similar to that of the sawing table I4 entering the sawing area, so they will not be described one by one.

[0048] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various variations or modifications within the scope of the claims, which do not affect the essence of the present invention.
