Description

Technical Field

[0001] The present invention relates to the technical field of sawing machines for high-speed cutting of continuous bar materials to a fixed length in an automated production line, and in particular to a swing sawing mechanism of a multi-saw head sawing machine capable of selectively adjusting the number of cutting segments. Background Art

[0002] In today's high-frequency welded pipe production line technology field, high-speed and ultra-high-speed continuous welded pipe production lines are appearing more and more frequently. With the development of technology, the requirements for the cutting technology of continuous pipe materials are becoming higher and higher, and the resulting high-speed double-saw cutting machine is gradually taking shape. Existing high-speed sawing machines all adopt a reciprocating cutting mode of a single saw car and a single saw blade. In this cutting mode, a saw car can only cut a continuous material once. When the saw car completes the cutting, it must return to its starting position and cycle for the next cutting task. This limits its maximum working efficiency both in the field of high-speed single saw car technology and in the field of synchronous reciprocating cutting technology of multiple saw cars. In order to further improve the cutting efficiency of the sawing machine and break through the limitation of the reciprocating cutting mode of a single saw car and a single saw blade, technical personnel in this field have developed a multi-saw head cutting machine with multiple saw heads working synchronously. However, in the single-drive multi-saw blade structural mode of the multi-saw head cutting machine, since multiple saw blades are usually connected to each other in series, there is a situation where multiple saw blades can only work at the same time or not work. When the entire sawing machine only needs a few of the multiple saw blades to participate in the work, and the other saw blades stop working to change the number of sawing segments of the material, it cannot be achieved. In order to solve such technical problems and realize the selective adjustment of the sawing segments, it has become an inevitable trend for technical personnel in this field to develop a swing sawing mechanism for a multi-saw head sawing machine. Summary of the Invention

[0003] This embodiment provides a swing sawing mechanism for a multi-saw head sawing machine that can break through the limitations of the reciprocating cutting mode of a single vehicle and a single saw blade, improve the cutting efficiency of the sawing machine, and realize the selective adjustment of the number of sawing segments. By arranging multiple groups of sawing devices under a saw vehicle module, and then arranging independent rotating devices and swinging drives for the sawing devices, each sawing device can swing or remain stationary relative to the base around the rotating device under the drive of the swinging drive to achieve adjustment of the number of sawing devices involved in the work at the same time, thereby ultimately realizing the selective adjustment of the number of sawing segments. This solution has a simple structure, strong reliability, and low cost.

[0023] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are intended to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. That is, the present invention is not limited to the preferred embodiments described, and the scope of the present invention is defined by the claims.

[0024] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified, “perpendicular” and “parallel” do not just have absolute meanings in a mathematical sense, but can be understood as “approximately perpendicular” and “approximately parallel”.

[0025] Figure 1 It is a schematic diagram of the basic structure of the overall layout of embodiment 1 of the present invention.

[0026] Figure 2 It is a side view schematic diagram of an embodiment of the present invention.

[0027] like Figure 1 and Figure 2As shown, this embodiment provides a multi-saw head sawing machine swing sawing mechanism that can break through the limitations of the reciprocating cutting mode of a single vehicle and a single saw blade, improve the cutting efficiency of the sawing machine, and achieve selective adjustment of the number of sawing segments. By arranging multiple sawing devices under a saw vehicle module, and then providing the sawing devices with independent rotating devices and swinging drives, each sawing device can swing or remain stationary relative to the base around the rotating device under the drive of the swinging drive to adjust the number of sawing devices simultaneously involved in the operation, ultimately achieving selective adjustment of the number of sawing segments. This solution has a simple structure, high reliability, and low cost. The specific structure of this embodiment in the first embodiment can include a base d, a drive q, a coupling y, and multiple sawing devices j. The multiple sawing devices j and the drive q are all arranged on the base d. The base d is configured as a bracket structure that rises upward from a plane and forms a cantilever suspension to one side. The end of the cantilever suspension is provided with a swing device zd. The rotating device zd is further provided with a rotating hole and a rotating shaft. The rotating hole is arranged on the cantilever suspension of the base d, and the rotating shaft is arranged on the sawing device j. The sawing device j can swing relative to the base d through the mutual cooperation between the rotating hole and the rotating shaft.

[0028] In this embodiment, the sawing devices j are preferably arranged in three groups, but may also be arranged in multiple groups. In this embodiment, the spatial arrangement of the driver q, coupling y, and the multiple sawing devices j on the base d from left to right is driver q, coupling y, sawing device j, coupling y, sawing device j, coupling y, sawing device j, and finally, sawing device j. The three groups of sawing devices j are neatly arranged in a row, and the multiple couplings y are connected in series via multiple coaxial drive shafts. The driver q is capable of synchronously driving the three groups of sawing devices j via the drive shafts. The continuous material w is continuously fed through the multiple sawing devices j arranged in a row in a spatial position near the base d in the same direction as the extension of the base d. The coupling y is provided between the multiple sawing devices j and the driver q to transmit torque. The driver q is capable of driving the coupling y to drive the multiple sawing devices j to cut the continuous material w into multiple segments.

[0030] Figure 6 It is a schematic diagram of a saw blade jp cutting a continuous material w according to an embodiment of the present invention.

[0031] like Figure 5 and Figure 6As shown, according to one aspect of a specific implementation of Example 1 of the present invention, a swing drive bd is further provided between the sawing device j and the base d. Each sawing device j can swing around the rotating device zd or remain stationary relative to the base d under the drive of the swing drive bd to adjust the number of sawing devices j simultaneously engaged in operation. When a sawing device j needs to be engaged in operation, the swing drive bd is activated to drive the sawing device j toward the continuous material w, thereby enabling the sawing device j to be engaged in operation. When a sawing device j does not need to be engaged in operation, the swing drive bd is retracted and deactivated, allowing the sawing device j to move away from the continuous material w, thereby enabling the sawing device j to be disengaged. The sawing device j is also provided with a saw blade jp. The swinging of the sawing device j enables the saw blade jp to feed and cut the continuous material w.

[0032] Figure 4 It is a cross-sectional schematic diagram of a clutch gear set ph according to an embodiment of the present invention.

[0033] like Figure 4 As shown, according to one aspect of a specific implementation of Example 1 of the present invention, the sawing device j is further provided with a clutch gear set ph, which further includes a drive gear pc and a clutch gear hc within the clutch gear set ph. The drive gear pc and the clutch gear hc are capable of meshing and transmitting with each other. The drive gear pc is coaxially connected in series with the driver q via a coupling y and a transmission shaft, and the clutch gear hc can engage or disengage the drive gear pc by moving closer to or further away from it.

[0034] Figure 3 It is a cross-sectional schematic diagram of a swing frame bdd according to an embodiment of the present invention.

[0035] Figure 7 It is a schematic diagram of a saw blade jp stopping working according to an embodiment of the present invention.

[0036] like Figure 3 and Figure 7As shown, according to one aspect of a specific implementation of Example 1 of the present invention, the sawing device j further includes a clutch frame add, a swing frame bdd, and a rotating shaft zz. In this embodiment, the clutch frame add and the swing frame bdd are both configured as welded steel structures. The rotating shaft of the rotating device zd is disposed at the upper end of the swing frame bdd. In this embodiment, the swing actuator bd is configured as a telescopic cylinder structure. One end of the swing actuator bd of the telescopic cylinder structure is hinged to the lower end of the swing frame bdd and the other end is hinged to the base d. The clutch frame add and the swing frame bdd are hinged to each other via the rotating shaft zz. In this embodiment, the width of the clutch frame add is smaller than the width of the swing frame bdd, and the clutch frame add can be placed inside the swing frame bdd. The clutch gear hc is mounted on the upper end of the clutch frame add, and the drive gear pc is mounted on a transmission shaft that passes through the swing frame bdd and is coaxial with the rotary shaft mounted on the swing frame bdd. A clutch driver hcq is also mounted between the clutch frame add and the swing frame bdd. The clutch driver hcq is also configured as a telescopic cylinder structure. One end of the clutch driver hcq is hinged to the swing frame bdd, and the other end is hinged to the clutch frame add. The clutch driver hcq can drive the clutch frame add to cause the clutch gear hc to swing about the rotation axis zz. The swinging motion of the clutch gear hc driven by the clutch frame add can move the clutch gear hc closer to or farther from the drive gear pc, thereby engaging or disengaging transmission.

[0037] According to one aspect of a specific implementation of Example 1 of the present invention, the clutch frame add is further provided with a driving sprocket p1, a driven sprocket p2, a tensioning pulley z, and a transmission chain cc. The transmission chain cc is wound around the driving sprocket p1, the driven sprocket p2, and the tensioning pulley z to form a chain drive mechanism. The driving sprocket p1 is disposed at the upper end of the clutch frame add and is fixedly mounted coaxially with the clutch gear hc. The driving sprocket p1 is capable of rotating synchronously with the clutch gear hc. The saw blade jp and the driven sprocket p2 are both mounted coaxially in series on the rotating shaft zz, and the driver q is capable of indirectly driving the saw blade jp through the chain drive mechanism. The driving sprocket p1 and the tensioning pulley z are both disposed on a side edge of the clutch frame add and exposed outside the swing frame bdd. The driving sprocket p1 and the tensioning pulley z extend through the side wall of the swing frame bdd via an extended shaft. Through holes are provided at corresponding locations on the side wall of the swing frame bdd to facilitate passage and the swinging of the clutch frame add.

[0038] According to one aspect of a specific implementation of Example 1 of the present invention, during operation, when three groups of sawing devices j arranged in a row are required to synchronously cut a continuous material w, the driver q is activated, driving all drive gears pc to rotate synchronously. All clutch drivers hcq are also activated, causing all clutch gears hc to mesh with their corresponding drive gears pc. Through the chain drive mechanism, all saw blades jp are ready to cut the continuous material w and rotate at high speed. Then, all swing drivers bd are activated, driving the sawing devices j and bringing the saw blades jp into contact with the continuous material w and severing it. When a particular sawing device j is not required to participate in operation, the corresponding swing driver bd is retracted and deactivated, allowing the sawing device j to move away from the continuous material w and thus not participate in operation. Simultaneously, the corresponding clutch driver hcq is retracted, pulling the corresponding clutch gear hc away from the drive gear pc, disconnecting the transmission and stopping the corresponding saw blade jp to conserve energy.

[0039] Figure 8 2 is a side view of a second embodiment of the present invention.

The clutch driver hcq is also arranged as a telescopic oil cylinder structure. One end of the clutch driver hcq of the telescopic oil cylinder structure is hinged to the swing frame bdd, and the other end is hinged to the clutch frame add. The clutch driver hcq can drive the clutch frame add to drive the clutch gear hc to swing around the rotating axis zz. The swinging action of the clutch gear hc driven by the clutch frame add can realize that the clutch gear hc approaches or moves away from the drive gear pc to achieve meshing transmission or cut-off transmission.

[0041] The clutch frame add is also equipped with a driving pulley u1, a driven pulley u2, a belt tensioner pw, and a transmission belt cp. The transmission belt cp is wound around the driving pulley u1, driven pulley u2, and belt tensioner pw, forming a belt drive mechanism. The driving pulley u1 is located at the upper end of the clutch frame add and is fixedly mounted coaxially with the clutch gear hc. The driving pulley u1 rotates synchronously with the clutch gear hc. The saw blade jp and driven pulley u2 are both mounted coaxially in series on the rotating shaft zz. The driver q indirectly drives the saw blade jp through the belt drive mechanism. The driving pulley u1 and belt tensioner pw are both located on a side edge of the clutch frame add and exposed outside the swing frame bdd. Both the driving pulley u1 and belt tensioner pw extend through the side wall of the swing frame bdd via extended shafts. Through holes are provided at corresponding locations on the side wall of the swing frame bdd to facilitate passage and the swinging of the clutch frame add.

[0044] like Figure 9 and Figure 10 As shown, according to one aspect of the specific implementation scheme of Example 3 of the present invention, its specific technical feature that distinguishes it from Example 1 is that the clutch gear hc is arranged at the upper end of the clutch frame add, the drive gear pc is arranged on the transmission shaft passing through the swing frame bdd and is coaxial with the rotary shaft arranged on the swing frame bdd, and a clutch driver hcq is further provided between the clutch frame add and the swing frame bdd. The clutch driver hcq is also configured as a telescopic oil cylinder structure, and one end of the clutch driver hcq of the telescopic oil cylinder structure is hinged to the swing frame bdd and the other end is hinged to the clutch frame add. The clutch driver hcq can drive the clutch frame add to drive the clutch gear hc to swing around the rotating shaft zz. The swinging action of the clutch gear hc driven by the clutch frame add can realize that the clutch gear hc approaches or moves away from the drive gear pc to achieve meshing transmission or cut-off transmission.

[0045] The clutch frame add is also provided with a driven gear cdc, which is installed on the rotating shaft zz and can engage with the clutch gear hc to form a gear transmission mechanism. The saw blade jp and the driven gear cdc are coaxially connected in series through the rotating shaft zz, and the driver q can indirectly drive the saw blade jp to rotate through the gear transmission mechanism.
