Description

Technical Field

[0001] The invention relates to the technical field of bending knives, and in particular to a bending knife wear detection method and a quick-maintenance bending knife device. Background Art

[0002] As key equipment in the field of metal processing, bending machines are mainly used to perform precise bending processing on metal plates of various thicknesses to meet the manufacturing needs of diversified products. As the core component of the bending machine, the performance and quality of the bending machine tool directly determine the success or failure of the entire processing process. The bending machine tool, as a component that directly acts on the metal plate, needs to withstand huge pressure and friction, so it must have high strength, high hardness and good wear resistance. At the same time, in order to adapt to the processing needs of plates of different materials, thicknesses and bending angles, the bending machine tool must also have a high degree of flexibility and adjustability. However, under long-term use, the press tool will wear faster and become unusable. At this time, it is necessary to detect it and replace it in time to ensure the normal use of the press tool.

[0003] In the field of metal processing and manufacturing, the bending machine is a key forming equipment. The selection and replacement of its tools are directly related to the processing efficiency and product quality. The traditional bending machine tool replacement methods vary according to the installation method of the tool. Among them, the flip tool change, although to a certain extent, meets the basic processing needs, but in actual application, it has exposed some shortcomings. During the flip tool change process, due to the heavy weight and complex structure of the tool, manual flipping is not only time-consuming and laborious, but also has safety hazards. When the operator flips the tool, it is easy to cause accidental injury due to improper force control or operational errors, which increases the risk of operation. In addition, the flip tool change has high requirements for the operating space. In a narrow or restricted working environment, the flip tool change may not be implemented due to insufficient space, which limits the flexibility and scope of application of the bending machine.

[0050] By adopting the above technical scheme, the hanging knife frame 31 is fixedly connected to the lower bottom end of the hanger 1, forming a stable working platform. The upward movement mechanism 6 configured inside it can drive the bending knife body 2 to perform a smooth upward movement through precise mechanical transmission, which provides great convenience for the replacement and maintenance of the tool. Below the upward movement mechanism 6, the setting of the limiting mechanism 7 plays a vital role. It can effectively limit the position of the bending knife body 2 during the movement process, and ensure that the tool will not accidentally slip or shift during adjustment or maintenance, thereby greatly improving the safety of operation.

A plurality of trapezoidal protrusions 22 are fixedly connected to the side of the outer wall of the bending knife body 2 away from the triangular bar 21.

[0052] By adopting the above technical solution, the presence of the triangular bar 21 can also enable the tool to produce a smoother sliding effect when inserted or pulled out, effectively reducing the resistance caused by friction, and further improving the operating efficiency. Below the triangular bar 21, the outer side wall of the bending knife body 2 is carefully provided with a limiting groove 23. This limiting groove 23 perfectly cooperates with the limiting mechanism 7 in the device, and can provide precise positioning and stable support during the rising or falling process of the tool.

[0053] See also Figure 5 - Figure 7 The bending knife body 2 is slidably sleeved inside the hanging knife frame 31, and the knife hanging mechanism 3 includes a first inner groove 34 opened inside the hanging knife frame 31 and located on one side of the bending knife body 2 for placing the upward movement mechanism 6, and a second inner groove 36 for placing the limiting mechanism 7 is opened inside the hanging knife frame 31 and located below the first inner groove 34, and a third inner groove 37 is opened inside the hanging knife frame 31 and located on one side of the first inner groove 34, and a plurality of cover plates 33 for covering are placed at the upper top of the hanging knife frame 31 corresponding to the position of the bending knife body 2.

[0054] By adopting the above technical scheme, the opening of the first inner groove 34 provides sufficient space for placing the upward mechanism 6, ensuring that the mechanism can work normally, and will not interfere with the sliding of the bending knife body 2, which not only improves the space utilization rate, but also makes the maintenance and maintenance of the upward mechanism 6 more convenient. The clever opening of the second inner groove 36 below the first inner groove 34 provides a perfect placement place for the limiting mechanism 7.

In addition, the third inner groove 37 located on one side of the first inner groove 34 inside the hanging knife frame 31 provides the necessary installation space for auxiliary components such as the transmission mechanism 8, which not only makes the structure of the entire device more reasonable and compact, but also ensures that all components can work together to achieve rapid maintenance and efficient use of the tool. The cover plate 33 can not only effectively prevent dust and debris from entering the device and causing damage to the tool and the mechanism, but also can reduce the noise to a certain extent.

[0056] By adopting the above technical scheme, the core component of the linear motion mechanism 4 includes a suspension frame 41 fixedly connected to the outer wall of the hanger 1. This design not only provides a stable installation platform for the drive motor 42, but also ensures the stability and reliability of the entire mechanism. The inner wall of the suspension frame 41 is carefully installed with the drive motor 42 as the power source of the entire moving mechanism. The drive motor 42 ensures that the threaded screw 44 can rotate smoothly and efficiently with its powerful driving force.

The first bearing frame 45 fixedly connected at the end of the outer wall of the hanger 1 away from the suspension frame 41 not only provides a stable support for the threaded screw 44, but also ensures the smoothness and stability of the screw during rotation through the rotational sleeve connection between the bearing and the threaded screw 44. The outer wall of the hanger 1 is symmetrically fixedly connected with two first bearing frames 45 above the threaded screw 44. This design not only enhances the stability of the entire mechanism, but also The optical axis 43 inside the two threaded screws 44 provides a perfect installation space. The addition of the optical axis 43 not only further improves the rigidity of the mechanism, but also ensures the stability and precision of the drive frame 46 during movement, so that the drive frame 46 can move linearly along the axial direction of the screw when the threaded screw 44 rotates, which not only ensures the stability of the drive frame 46 during movement, but also avoids the resistance caused by friction, thereby further improving the movement efficiency. The telescopic end of the first electric push rod 51 is fixedly connected with a lower pressure plate 53. This design enables the lower pressure plate 53 to move up and down quickly and smoothly under the drive of the electric push rod.

The coaxial fixed connection between the spur gear 61 and the guide plate 62 adds additional stability and synchronization to the upward movement mechanism 6. The design of the arc guide groove 63 not only increases the surface area of ​​the guide plate 62 and improves the contact area with the guide rod 66, but also enables the guide rod 66 to move smoothly along a predetermined trajectory under the guidance of the arc guide groove 63, which not only improves the movement accuracy of the upward movement mechanism 6, but also ensures the tool In order to ensure stability and safety during the adjustment process, the interior of the hanging knife frame 31 is located at the inner bottom end of the first inner groove 34, and two second guide frames 64 are symmetrically fixedly connected.

The inner side wall of the third inner groove 37 inside the hanging knife frame 31 is symmetrically fixedly connected with a second electric push rod 86, and the ends of the two second electric push rods 86 are fixedly connected with bearing rings 87. The interiors of the two bearing rings 87 are rotatably sleeved with a tensioning wheel 88 for controlling the tensioning of the synchronous belt 85 through bearings. The two second electric push rods 86 are respectively located at both sides of the synchronous belt 85.

[0062] By adopting the above technical solution, the first bevel gear 82 and the spur gear 61 are coaxially fixedly connected together, which not only realizes the close cooperation between the upward movement mechanism 6 and the transmission mechanism 8, but also ensures that the power can be quickly and accurately transmitted from the spur gear 61 to the first bevel gear 82. Through this transmission mode, the upward movement mechanism 6 can respond quickly when receiving the power, and perform efficient movement and adjustment. At the same time, through the rotation of the synchronous wheel 84, the synchronous belt 85 can smoothly transmit the power, thereby realizing the precise driving of the fixed rod 76 and the winding wheel 75. The ends of the two second electric push rods 86 are fixedly connected to the bearing ring 87, which not only provides a perfect installation space for the tensioning wheel 88, but also ensures that the tensioning wheel 88 can rotate smoothly inside the bearing ring 87 through the bearing. Through the support and guidance of the bearing ring 87, the tensioning wheel 88 can always maintain close contact with the synchronous belt 85, thereby realizing the continuous adjustment and maintenance of the tension of the synchronous belt 85, thereby ensuring the stability and accuracy of the transmission.

[0063] For the replacement of the damaged bending knife body 2: the cover plate 33 above the damaged bending knife body 2 will be removed, and then the driving motor 42 will be controlled to drive the threaded screw 44 to rotate, and the threaded screw 44 is threadedly sleeved with the driving frame 46, so under the guidance of the optical axis 43, the lateral movement of the driving frame 46 can be realized. Therefore, when the driving frame 46 moves to the top of the damaged bending knife body 2, the telescopic end of the first electric push rod 51 can be controlled to move downward, and the lower pressure plate 53 connected with the telescopic end of the first electric push rod 51 enters into the interior of the hanging knife frame 31 through the opening 32. Since the outer wall of the lower pressure plate 53 is provided with a tooth groove 54 which meshes with the spur gear 61 for transmission, the spur gear 61 will drive the first bevel gear 82 and the guide plate 62 to rotate, and the first bevel gear 82 rotates and meshes with the first The second bevel gear 83 meshes with and drives the synchronous wheel 84 to rotate. At this time, the synchronous wheel 84 drives the fixing rod 76 below to rotate through the synchronous belt 85. After the fixing rod 76 drives the winding wheel 75 to rotate, the traction rope 73 is gradually wound around the outer wall of the winding wheel 75. Because the guide of the guide wheel 74 and the inner bottom end of the limit block 71 that is slidably connected to the second inner groove 36, when the traction rope 73 is wound around the winding wheel 75, the limit block 71 is pulled out from the inside of the limit groove 23, and the limit block 71 will synchronously compress the limit spring 72 at this time. When the limit block 71 is completely separated from the limit groove 23, the bending knife body 2 is no longer restricted. Because the lower bottom end of the trapezoidal protrusion 22 contacts the inner bottom end of the trapezoidal guide groove 65, the bending knife body 2 still does not move when no force is applied.

[0064] When the guide plate 62 is driven by the spur gear 61 to rotate, since the internal rotating sleeve of the arc guide groove 63 is connected with the guide rod 66, when the guide plate 62 rotates, it will drive the upper moving frame 67 to move upward through the guide rod 66. At this time, the limit groove 23 is separated from the limit block 71, the diameter of the avoidance groove 69 is further reduced, and the upper moving frame 67 will be closer to the triangular bar 21. When the upper moving frame 67 contacts the triangular bar 21, as the telescopic end of the first electric push rod 51 continues to drive the lower pressure plate 53 to move downward, the spur gear 61 continues to drive the guide plate 62 to rotate, and can drive the triangular bar 21 and the bending knife body 2 to continue to rise through the upper moving frame 67. After the arc-shaped guide groove 63 drives the guide rod 66 to move to the maximum end point, the upper moving frame 67 cannot rise, and the end of the bending knife body 2 will also leave the interior of the hanging knife frame 31. Since the spur gear 61 always drives the first bevel gear 82 and the second bevel gear 83 to rotate, the elastic force of the limit spring 72 will also reach the limit position, causing the limit block 71 to be unable to continue to shrink. In this process, the bearing ring 87 can be driven to shrink by controlling the telescopic end of the second electric push rod 86, and the bearing ring 87 controls the contact surface between the tensioning wheel 88 and the synchronous belt 85 to adjust the tension of the synchronous wheel 84 and the synchronous belt 85. When it is loose, it is impossible to The locking cam 72 is engaged to the locking cam 71 and the locking cam 73 is engaged to the locking cam 72. When the locking cam 71 is engaged, the locking cam 72 is engaged to the locking cam 73. After that, it is necessary to control the tension of the synchronous belt 85 so that it is no longer in a relaxed state, to ensure that when the bending knife body 2 needs to be taken out, the synchronous wheel 84 can drive the fixing rod 76 to rotate through the synchronous belt 85, to ensure that the limit block 71 can be separated from the bending knife body 2 after being pulled by force. Since the traction rope 73 may be in a relaxed state and fall off the guide wheel 74 during the squeezing of the limit block 71, the traction rope 73 can be wrapped around the guide wheel 74 instead of abutting against it, thereby ensuring that the traction rope 73 can move normally. At this time, even if the traction rope 73 is in a relaxed state, it will not fall off the guide wheel 74.
