Description

Technical Field

[0001] This invention relates to the field of tool magazine mechanisms, and more particularly to a freely combinable tool magazine mechanism and its tool changing method. Background Technology

[0002] Bending machines can automatically bend sheet metal workpieces. A single positioning of a sheet metal workpiece can be used to bend multiple sides, effectively shortening the bending processing time of sheet metal workpieces and greatly improving the forming accuracy and processing efficiency of sheet metal workpieces.

[0003] In existing technologies, the blades in the tool magazine mechanism of traditional bending machines are mostly fixed and immovable. Due to the limitations of the blade combination, it is impossible to process sheet metal workpieces of arbitrary shapes and sizes. When bending the sheet metal at different angles is required, the machine must be stopped to replace the bending head, which is time-consuming, labor-intensive, and cumbersome to adjust, reducing the bending efficiency of sheet metal workpieces and also affecting bending accuracy. In addition, bending machines on the market that can achieve automatic tool changing have particularly complex tool changing structures, high manufacturing costs, and very high maintenance costs in the later stages.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a tool magazine mechanism and tool changing method that can be freely combined, has a fast combination, improves tool changing efficiency, and has a high degree of automation.

[0006] The technical solution of the present invention is as follows: a freely combinable tool magazine mechanism, including a transverse shifting mechanism, a transverse pushing mechanism, a rotating pushing block, a rotating mechanism, and a plurality of blades;

[0007] The lateral shifting mechanism is connected to the lateral pusher mechanism. The lateral pusher mechanism is connected to the rotating mechanism through a rotating pusher block. The blade is mounted on the side of the rotating mechanism via a movable shaft. The rotating mechanism can drive the rotating pusher block to rotate and push the rotating pusher block into connection with the blade through the lateral pusher mechanism. Then, the blade connected to the rotating pusher block is rotated through the rotating mechanism to achieve blade replacement.

[0008] The rotating pusher block includes a rotating part and an insert shaft part. The rotating part is connected to a rotating shaft, and the insert shaft part is disposed on the rotating part. The blade is provided with an insertion hole. The rotating part can drive the insert shaft part to rotate so that the transverse pusher mechanism can align the insert shaft part with the insertion hole for insertion and connection.

[0009] Using the above technical solution, in the freely combinable tool magazine mechanism, the lateral shifting mechanism includes a pushing cylinder, a lateral shifting plate, a first slide rail, and a first slider. The first slide rail is connected to the lateral shifting plate through the first slider. The pushing cylinder is connected to the side end of the lateral shifting plate. The lateral pushing mechanism and the rotating mechanism are located on the lateral shifting plate.

[0010] Using the above technical solutions, in the freely combinable tool magazine mechanism, the rotating mechanism includes a first motor and a rotating shaft. The output shaft of the first motor is connected to the rotating shaft. A plurality of blades are provided on the side of the rotating shaft away from the first motor. The rotating pusher block is sleeved on the rotating shaft between the first motor and the blades.

[0011] Using the above technical solutions, in the freely combinable tool magazine mechanism, the transverse pusher mechanism includes a second motor, a lead screw, a nut seat, and a connecting block. The output shaft of the second motor is connected to the lead screw, the nut seat is sleeved on the lead screw, and the connecting block is provided on the nut seat. The connecting block is movably connected to the rotating pusher block.

[0012] In the freely combinable blade magazine mechanism described above, bearing stops are provided at both ends of the blade to restrict its movement.

[0013] Using the above-mentioned technical solutions, in the freely combinable tool magazine mechanism, the transverse pusher mechanism further includes a sliding arm, a second slide rail, a second slider, and an upper support block. The transverse plate is provided with a rectangular groove, and the sliding arm is inserted through the rectangular groove. One end of the sliding arm is connected to a connecting block, and the other end of the sliding arm is connected to the second slider. The second slider is located on the second slide rail, and the upper support block is located at the bottom of the second slider. The back of the blade is provided with a lower pressing block, and the bottom surface of the upper support block abuts against the lower pressing block.

[0014] In the freely combinable tool magazine mechanism described above, the rotating shaft is provided with several transverse grooves, the rotating part of the rotating pusher block is provided with a shaft hole, and the inner sidewall of the shaft hole is provided with a locking block that engages with the transverse grooves.

[0015] Using the above-mentioned technical solutions, in the freely combinable blade magazine mechanism, the thickness of the blade is 2-10mm.

[0016] In the freely combinable tool magazine mechanism described above, the transverse pusher mechanism further includes a third slide rail and a third slider. The third slide rail is mounted on the transverse plate, and the bottom of the connecting block is movably connected to the third slide rail via the third slider.

[0017] The present invention also provides a tool changing method, which is applied to the freely combinable tool magazine mechanism described in any of the above technical solutions, the tool changing method comprising the following steps:

[0018] Step S1: The rotating mechanism can rotate the pusher block downwards by rotating the pusher block so that the insert shaft of the pusher block is aligned with the insertion hole on the blade.

[0019] Step S2: Subsequently, the transverse pusher mechanism pushes the insert shaft of the rotating pusher block to move laterally, so as to insert the insert shaft into the insertion hole of the blade;

[0020] Step S3: Next, the rotating mechanism can rotate the pusher block upwards by rotating the pusher block, so as to adjust the width of the blade by rotating the blade angle;

[0021] Step S4: Finally, the lateral shifting mechanism can drive the blade to shift, so as to adjust the position of the blade.

[0022] Compared with the prior art, the rotating mechanism of the present invention can rotate the rotating part of the rotating pusher block downward to align the insert shaft part of the rotating pusher block with the insertion hole on the blade. Then, the lateral pusher mechanism pushes the insert shaft part of the rotating pusher block laterally to insert the insert shaft part into the insertion hole of the blade. Next, the rotating mechanism can rotate the rotating part of the rotating pusher block upward to adjust the width of the blade by rotating the blade angle. Finally, the lateral shifting mechanism can shift the blade to adjust its position, thereby completing the blade changing operation. The tool magazine mechanism of the present invention can automatically adjust the position and length of the blade to achieve blade combinations of arbitrary lengths, thereby enabling bending processing of sheet metal workpieces of different sizes and angles. The overall structure is reasonably designed, easy to combine, eliminates the trouble of manual adjustment, and has high processing efficiency, making it suitable for widespread use.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] like Figures 1 to 5 As shown, a freely combinable tool magazine mechanism includes a transverse shifting mechanism 1, a transverse pushing mechanism 2, a rotating pushing block 3, a rotating mechanism 4, and several blades 5.

[0031] The transverse shifting mechanism 1 is connected to the transverse pusher mechanism 2. The transverse pusher mechanism 2 is connected to the rotating mechanism 4 through the rotating pusher block 3. The blade 5 is mounted on the side of the rotating mechanism 4 through a movable shaft. The rotating mechanism 4 can drive the rotating pusher block 3 to rotate and push the rotating pusher block 3 into connection with the blade 5 through the transverse pusher mechanism 2. Then, the blade 5 connected to the rotating pusher block 3 is rotated through the rotating mechanism 4 to achieve blade replacement.

[0032] The rotating pusher block 3 includes a rotating part 31 and an insert shaft part 32. The rotating part 31 is connected to the rotating shaft 42, and the insert shaft part 32 is disposed on the rotating part 31. The blade 5 is provided with an insertion hole 51. The rotating part 31 can drive the insert shaft part 32 to rotate so that the transverse pusher mechanism 2 can align the insert shaft part 32 with the insertion hole 51 for insertion and connection. The rotating mechanism 4 can be driven to flip downward by the rotating part 31 of the rotating pusher block 3, so that the insert shaft part 32 of the rotating pusher block 3 is aligned with the insertion hole 51 on the blade 5. Then, the transverse pusher mechanism 2 pushes the insert shaft part 32 of the rotating pusher block 3 to move laterally, so that the insert shaft part 32 is inserted into the insertion hole 51 of the blade 5. Next, the rotating mechanism 4 can be driven to flip upward by the rotating part 31 of the rotating pusher block 3, so that the width of the blade 5 can be adjusted by rotating the blade 5. Finally, the transverse shifting mechanism 1 can drive the blade 5 to shift, so as to adjust the position of the blade 5, thereby completing the tool changing operation. This tool magazine mechanism can automatically adjust the position and length of the blade 5 to realize the combination of blades 5 of any length, so as to perform bending processing on sheet metal workpieces of different sizes and angles.

[0033] like Figure 1 and Figure 2As shown, the lateral shifting mechanism 1 further includes a push cylinder (not shown), a lateral shifting plate 11, a first slide rail 12, and a first slider 13. The first slide rail 12 is connected to the lateral shifting plate 11 via the first slider 13. The push cylinder is connected to the side end of the lateral shifting plate 11. The lateral pusher mechanism 2 and the rotating mechanism 4 are mounted on the lateral shifting plate 11. The push cylinder can drive the lateral shifting plate 11 to move laterally on the first slide rail 12 to move the position of the blade 5.

[0034] like Figure 4 As shown, the rotating mechanism 4 further includes a first motor 41 and a rotating shaft 42. The output shaft of the first motor 41 is connected to the rotating shaft 42. A plurality of blades 5 are provided on the side of the rotating shaft 42 away from the first motor 41. The rotating pusher block 3 is sleeved on the rotating shaft 42 between the first motor 41 and the blades 5. The first motor 41 can drive the rotating shaft 42 to rotate, thereby driving the rotating pusher block 3 on the rotating shaft 42 to rotate and adjust.

[0035] like Figures 1 to 3 As shown, the transverse pusher mechanism 2 further includes a second motor 21, a lead screw 22, a nut seat 23, and a connecting block 24. The output shaft of the second motor 21 is connected to the lead screw 22. The nut seat 23 is sleeved on the lead screw 22, and the connecting block 24 is provided on the nut seat 23. The connecting block 24 is movably connected to the rotating pusher block 3. The transverse pusher mechanism 2 can push the rotating pusher block 3 to move laterally, so that the rotating pusher block 3 drives the insert shaft part 32 to align with the insertion hole 51 of the blade 5 for insertion. Specifically, the second motor 21 can drive the lead screw 22 to rotate, so as to drive the nut seat 23 located on the lead screw 22 to move. Since the nut seat 23 is connected to the rotating pusher block 3 through the connecting block 24, it pushes the rotating pusher block 3 to move laterally.

[0036] like Figure 1 As shown, furthermore, the left and right ends of the blade 5 are respectively provided with bearing stops 52 for restricting the movement of the blade 5. The bearing stops 52 can prevent the blade 5 from shifting during the insertion and connection with the rotating pusher block 3.

[0037] like Figure 2 and Figure 3As shown, the transverse pusher mechanism 2 further includes a sliding arm 25, a second slide rail 26, a second slider 27, and an upper support block 28. The transverse plate 11 is provided with a rectangular groove 110. The sliding arm 25 is inserted through the rectangular groove 110. One end of the sliding arm 25 is connected to the connecting block 24, and the other end of the sliding arm 25 is connected to the second slider 27. The second slider 27 is provided on the second slide rail 26. The upper support block 28 is provided at the bottom of the second slider 27. The back of the blade 5 is provided with a lower pressing block 53. The upper support block 28 abuts against the bottom surface of the lower pressing block 53. When the connecting block 24 moves laterally under the action of the nut seat 23, the sliding arm 25 can drive the second slider 27 to move on the second slide rail 26. Since the bottom of the second slider 27 is provided with an upper support block 28, when the second slider 27 drives the upper support block 28 to slide to the bottom of the lower pressure block 53 of the blade 5, the blade 5 can be limited. At this time, the blade 5 cannot be driven to rotate by the rotating pusher block 3. The setting of the upper support block 28 improves the assembly structure stability of the blade 5.

[0038] like Figure 4 and Figure 5 As shown, furthermore, the rotating shaft 42 is provided with a plurality of transverse grooves 421, and the rotating part 31 of the rotating pusher block 3 is provided with a shaft hole. The inner sidewall of the shaft hole is provided with a locking block 311 that engages with the transverse grooves 421. The locking block 311 on the rotating pusher block 3 can engage with the transverse grooves 421 on the rotating shaft 42. When the rotating shaft 42 rotates, it can drive the rotating pusher block 3 to rotate.

[0039] Furthermore, the thickness of the blade 5 is 2-10mm. In this embodiment, the thickness of the blade 5 is 5mm. Of course, it should be noted that users can also set the blade 5 to other thicknesses according to actual conditions, and this embodiment does not impose too many restrictions.

[0040] Furthermore, the transverse pusher mechanism 2 also includes a third slide rail 291 and a third slider 292. The third slide rail 291 is disposed on the transverse plate 11, and the bottom of the connecting block 24 is movably connected to the third slide rail 291 via the third slider 292. The arrangement of the third slide rail 291 and the third slider 292 can improve the movement stability of the transverse plate 11.

[0041] This embodiment also provides a tool changing method applied to the aforementioned freely combinable tool magazine mechanism, the tool changing method comprising the following steps:

[0042] Step S1: The rotating mechanism 4 can be driven to flip downward by the rotating part 31 of the rotating pusher block 3 so as to align the insert shaft part 32 of the rotating pusher block 3 with the insertion hole 51 on the blade 5.

[0043] Step S2: Then the transverse pusher mechanism 2 pushes the insert shaft part 32 of the rotating pusher block 3 to move laterally, so as to insert the insert shaft part 32 into the insertion hole 51 of the blade 5;

[0044] Step S3: Next, the rotating mechanism 4 can rotate the rotating part 31 of the rotating pusher block 3 to rotate it upward, so as to adjust the width of the blade 5 by rotating the blade 5 angle.

[0045] Step S4: Finally, the transverse shifting mechanism 1 can drive the blade 5 to shift, so as to adjust the position of the blade 5.

[0046] Compared with the prior art, the rotating mechanism of the present invention can rotate the rotating part of the rotating pusher block downward to align the insert shaft part of the rotating pusher block with the insertion hole on the blade. Then, the lateral pusher mechanism pushes the insert shaft part of the rotating pusher block laterally to insert the insert shaft part into the insertion hole of the blade. Next, the rotating mechanism can rotate the rotating part of the rotating pusher block upward to adjust the width of the blade by rotating the blade angle. Finally, the lateral shifting mechanism can shift the blade to adjust its position, thereby completing the blade changing operation. The tool magazine mechanism of the present invention can automatically adjust the position and length of the blade to achieve blade combinations of arbitrary lengths, thereby enabling bending processing of sheet metal workpieces of different sizes and angles. The overall structure is reasonably designed, easy to combine, eliminates the trouble of manual adjustment, and has high processing efficiency, making it suitable for widespread use.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
