Description

Technical Field

[0001] This utility model relates to the field of guide structure technology, and in particular to a slider guide device for a CNC bending machine. Background Technology

[0002] In CNC bending machines, the slider is typically guided by guide mechanisms on both sides and guide rails on the support. This guiding method ensures the slider's operational stability to a certain extent. However, due to the large size of the slider and the lack of a support point on the back side, the slider is prone to slight wobbling during bending operations, especially at the end of the stroke. This wobbling threatens the product's accuracy and stability. Therefore, there is an urgent need for a new guiding device that can further improve the slider's stroke stability based on the existing guide rails and guide mechanisms on both sides, thereby improving product quality and production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Although traditional guide rails and guide mechanisms can provide some guidance support, when the slider enters the final stage of its stroke, due to the lack of stable support on the back side, the slider will be subjected to a large lateral force, which will lead to increased wear on the guide mechanism and guide rails, and may even cause the slider to deviate, affecting the flatness and squareness of the product.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A CNC bending machine slider guide device includes a slider. The back side of the slider is provided with reinforcing ribs along the bending groove direction. A plurality of guide grooves are equally spaced along the outer side of the reinforcing ribs. A crossbeam is connected between the two ends of the back side of the slider and the machine frame. Two crossbeams are arranged vertically and parallel to each other. A plurality of guide rods are vertically connected between the crossbeams. The guide rods are built into the guide grooves. A guide wheel is provided in the guide grooves outside the guide rods.

[0006] Furthermore, the number of guide grooves and guide rods is the same.

[0007] Furthermore, the inner side of the guide groove has a semi-circular arc structure, and the semi-circular arc portion of the guide groove is provided with a protrusion.

[0008] Furthermore, the guide rod has a vertically oriented positioning guide groove corresponding to the protrusion.

[0009] Furthermore, a support plate is provided between the back sides of the two crossbeams, corresponding to the guide rod. The support plate has a matching groove corresponding to the guide wheel, and a protruding arc part is provided in the matching groove.

[0010] Furthermore, the guide wheel is a concave roller, and both ends of the guide wheel are rotatably connected to the guide groove via a rotating shaft. A rubber pad is provided around the guide wheel.

[0011] Furthermore, while the guide rod is partially attached to one side of the guide wheel, the guide wheel is partially attached to the other side of the guide wheel.

[0012] Furthermore, the arc-shaped component is made of polytetrafluoroethylene.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting reinforcing ribs and guide grooves on the back side of the slider, and in conjunction with the design of the crossbeam and guide rod, a stable support is provided for the slider on the back side. This design effectively reduces the slight wobbling of the slider at the end of the stroke due to the lack of a fulcrum, thereby ensuring the stability of the slider throughout the entire stroke and improving the accuracy and stability of the product.

[0015] The design of the guide groove in conjunction with the guide rod and guide wheel disperses and reduces the lateral force on the slider during movement, thereby reducing the wear of the guide mechanism and guide plate. This not only extends the service life of the equipment but also reduces downtime for maintenance due to wear (workpiece machining deviation) and improves production efficiency.

[0016] In summary, because the stability of the slider during its stroke is significantly improved, the flatness and squareness of the processed products are also correspondingly improved. Attached Figure Description

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, this utility model provides a technical solution for a slider guide device for a CNC bending machine. The device mainly includes a slider 1. A reinforcing rib 2 is designed on the back side of the slider 1 along the direction of the bending groove to enhance the strength and stability of the slider. Several guide grooves 21 are opened at equal intervals along the outer side of the reinforcing rib 2. These guide grooves 21 are used to cooperate with the subsequent guide rod 4 to achieve precise guidance of the slider 1.

[0026] Between the two end frames on the back side of slider 1, there are two horizontal beams 3 arranged parallel to each other.

[0027] Several guide rods 4 are vertically connected between the two crossbeams 3. These guide rods 4 are built into the guide groove 21, thereby realizing a stable connection and guidance between the slider 1 and the frame.

[0028] To further improve the accuracy and stability of the guide, guide wheels 5 are also provided inside the guide groove 21 on the outside of the guide rod 4. These guide wheels 5 can roll as the slider 1 moves, reducing friction and wear, while ensuring the smoothness of the slider during movement.

[0029] Example 2

[0030] Based on Example 1, Example 2 further optimizes the design of the guide groove 21 and the guide rod 4:

[0031] First, the number of guide grooves 21 and guide rods 4 is designed to be the same to ensure that each guide groove 21 can cooperate with the corresponding guide rod 4 to achieve comprehensive guidance and support.

[0032] Secondly, the inner side of the guide groove 21 is designed as a semi-circular arc structure, and a protrusion 22 is provided in the semi-circular arc part; correspondingly, a positioning guide groove 41 is also vertically opened on the guide rod 4 to cooperate with the protrusion 22, thereby further fixing the position of the guide rod 4 and preventing it from shifting during movement.

[0033] In addition, a support plate 6 is provided between the back sides of the two crossbeams 3 at the position corresponding to the guide rod 4. A matching groove 61 is opened on the support plate 6 at the position corresponding to the guide wheel 5, and an arc part 62 is raised in the matching groove 61. These arc parts 62 are made of polytetrafluoroethylene, which has excellent wear resistance and self-lubricating properties, and can further reduce the friction and wear between the guide wheel 5 and the support plate 6.

[0034] The guide wheel 5 is designed as a concave roller, with its two ends rotatably connected to the guide groove 21 via a rotating shaft. A rubber pad 51 is also provided on the periphery of the guide wheel 5 to increase the friction between the guide groove 21 and the support plate 6, while reducing wear and noise.

[0035] It is worth noting that in embodiment 2, while the guide rod 4 is in contact with one side of the guide wheel 5, the guide wheel 5 is also in contact with the other side of the guide wheel 5 (i.e., the adjacent guide wheel 5), that is, the guide wheel 5 rolls between the guide rod 4 and the support plate 6. This design can further improve the accuracy and stability of the guidance.

[0036] The working process of this utility model is as follows: When using this CNC bending machine slider guide device (based on the existing guide mechanisms on both sides and the guide rail plate on the bracket), the slider 1 needs to be installed on the frame of the CNC bending machine first, and the reinforcing rib 2 and guide groove 21 need to be correctly aligned with the crossbeam 3 and guide rod 4 on the frame. Then, the CNC bending machine is started, and the slider 1 will move along the direction of the bending groove under the drive of the motor. During the movement, the guide rod 4 will slide along the guide groove 21, and the guide wheel 5 will roll in the matching groove 61 of the guide groove 21 and the support plate 6. Due to the design of the guide groove 21 and the guide rod 4 and the presence of the guide wheel 5, the slider 1 will remain stable and smooth during the movement, and there will be no shaking or deviation. When the slider 1 moves to the bending position, the CNC bending machine will perform the bending operation. At this time, since the slider has been stably guided and supported, the accuracy and stability of the bending operation can be ensured.

[0037] In summary, the guide device for the slider 1 of this CNC bending machine, through the design of the guide groove 21, guide rod 4 and guide wheel 5, achieves smooth and stable guidance of the slider 1 during movement, thereby improving the processing accuracy and production efficiency of the CNC bending machine.
