Description

Technical Field

[0001] The utility model relates to the technical field of profile punching, in particular to a numerical control frame punching machine. Background Art

[0002] In profile manufacturing, frames often need to be punched, especially side holes. In order to cooperate with other parts, the position and aperture of the side holes need to be accurate. When punching some long frames, they are prone to collapse, resulting in a decrease in the quality of the punching.

[0003] In the prior art, an invention patent (CN117259562A) discloses a profile punching device, which relates to the field of profile processing devices, and includes a support frame, a translation mechanism, a profile fixing mechanism, a punching die and a waste mechanism; a translation mechanism and a profile fixing mechanism are arranged on the top of the support frame, and the profile fixing mechanism is distributed at both ends of the translation mechanism; a punching die is installed on the translation mechanism, and a waste mechanism is arranged at the bottom of the punching die; the profile fixing mechanism is used to fix the two ends of the profile, and the translation mechanism is used to drive the punching die to punch different positions of the profile. The device cannot fully support the frame of the long profile. When punching the frame of the long profile, the long profile will collapse, resulting in a decrease in the punching quality.

[0004] Based on this, the technical problem solved in this case is: how to provide a method to improve the punching quality for long frames. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a CNC frame punching machine.

[0006] The technical solution of the utility model is:

[0007] A CNC frame punching machine comprises a frame, a punching mechanism, a horizontal driving device, a clamping mechanism, and a support frame. The horizontal driving device is connected to the frame, and the punching mechanism and the clamping mechanism are both connected to the horizontal driving device, and the clamping mechanism is located between the punching mechanisms. The horizontal driving device is used to drive the punching mechanism and the clamping mechanism to move horizontally along the length direction of an external frame profile. The support frame is connected to the frame, and a lifting mechanism is provided on the frame for driving the support frame to move upward and downward. The support frame is used to support the long frame profile so that the long frame profile remains in a horizontal state; the lifting mechanism is linked to the horizontal driving device. When the punching mechanism is close to the support frame, the lifting mechanism drives the support frame downward, and when the punching mechanism is away from the support frame, the lifting mechanism drives the support frame upward.

[0008] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:

[0009] The utility model can maintain the parallelism of the long frame profile through the support frame, and can avoid the punching mechanism through the lifting mechanism, and effectively prevent the long frame profile from being too long and causing the middle part to collapse downward. When the middle part of the long frame profile collapses downward, the inside of the long frame profile will be worn when the punching mechanism moves, and the support frame can prevent the punching mechanism from wearing the long frame profile. On the other hand, the lifting mechanism can lower the support frame when the punching mechanism is about to contact the support frame to avoid the punching mechanism. When the punching mechanism is away from the support frame, the lifting mechanism will raise the support frame to re-support the long frame profile. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Example 1

[0016] See also Figure 1-4 A CNC frame punching machine comprises a frame 1, a punching mechanism 2, a horizontal driving device 3, a clamping mechanism 4, and a support frame 5. The horizontal driving device 3 is connected to the frame 1, the punching mechanism 2 and the clamping mechanism 4 are both connected to the horizontal driving device 3, and the clamping mechanism 4 is located between the punching mechanisms 2. The horizontal driving device 3 is used to drive the punching mechanism 2 and the clamping mechanism 4 to move horizontally along the length direction of the external frame profile 7. A lifting mechanism 13 is provided on the frame 1, and the support frame 5 is connected to the lifting mechanism 13. The support frame 5 is used to support the long frame profile 7 so that the long frame profile 7 remains in a horizontal state; the lifting mechanism 13 is linked with the horizontal driving device 3. When the punching mechanism 2 is close to the support frame 5, the lifting mechanism 13 drives the support frame 5 downward, and when the punching mechanism 2 is away from the support frame 5, the lifting mechanism 13 drives the support frame 5 upward.

[0017] In actual use, the staff places the long frame profile 7 on the frame 1 and locates it at the working position of the punching mechanism 2 and the pressing mechanism 4. In particular, the staff can pre-set the punching specifications and punching distances to be punched, and then start the equipment. The horizontal driving device 3 will drive the punching mechanism 2 and the pressing mechanism 4 to move horizontally along the length direction of the frame profile 7. When moving to the set distance, the frame profile 7 is punched, and the punching size specifications are also pre-set. Then, it is taken to the next punching position through the horizontal driving device 3 to continue punching until all the set punchings are completed. However, when punching the middle section of the long frame profile 7, the middle section of the long frame profile 7 is The part will collapse downward, causing the punching mechanism 2 to wear the long frame profile 7 when it moves to the collapsed part, and there will also be a certain amount of wear on the punching mechanism 2. In order to avoid this situation, the design of the support frame 5 can provide support for the middle part of the long frame profile 7, so that the long frame profile 7 can maintain its horizontality during punching. On the other hand, when the frame profile 7 is punching and the punching mechanism 2 is about to contact the support frame 5, the lifting mechanism 13 lowers the support frame 5 to avoid the punching mechanism 2. When the punching mechanism 2 leaves the support frame 5, the lifting mechanism 13 raises the support frame 5 to support the long frame profile 7 again to ensure the parallelism of the punching. Specifically, the punching mechanism 2 is a drilling machine or other equipment that can complete punching.

[0018] Furthermore, the lifting mechanism 13 is a driving cylinder, the cylinder body of the driving cylinder is connected to the frame, the power output part of the driving cylinder is connected to the support frame 5, and the lifting mechanism 13 can drive the support frame 5 to move upward or downward.

[0019] Through the above design, the lifting mechanism 13 can drive the support frame 5 downward to avoid the punching mechanism 2, and can also drive the support frame 5 upward to support the long frame profile 7.

[0020] Furthermore, the support frame 5 is provided with a groove 51 , and the groove 51 is symmetrically connected to the support frame 5 , and the groove 51 is used to place the long frame profile 7 of the peripheral.

[0021] Through the above design, the groove 51 on the support frame 5 can be used to place one side of the long frame profile 7 to ensure the stability of the punching of the long frame profile 7, that is, to improve the quality of the punching of the long frame profile 7.

[0022] Preferably, the horizontal driving device 3 includes a slide rail 31 connected to the frame 1 and a first sliding plate 32 slidably connected to the slide rail 31. The punching mechanism 2 and the clamping mechanism 4 are both fixedly connected to the first sliding plate 32, and the punching mechanism 2 is symmetrically connected at both ends of the first sliding plate 32. The punching mechanism 2 and the clamping mechanism 4 can move horizontally along the length direction of the external frame profile 7 under the action of the first sliding plate 32.

[0023] In this embodiment, the punching mechanism 2 and the pressing mechanism 4 can be moved synchronously through the first sliding plate 32 and the slide rail 31, and can be moved horizontally along the length direction of the frame, thereby improving the punching accuracy to a certain extent.

[0024] More preferably, the frame 1 further includes a limiting mechanism 6 and a second sliding plate 11, the second sliding plate 11 is slidably connected to the slide rail 31, the limiting mechanism 6 includes a first limiting unit 61 and a second limiting unit 62, the first limiting unit 61 is fixedly connected to one end of the frame 1, the second limiting unit 62 is fixedly connected to the second sliding plate 11, and the second sliding plate 11 can be used to adjust the position of the second limiting unit 62 on the frame 1.

[0025] In this embodiment, the second sliding plate 11 is connected to a second limiting unit 62, and the second limiting unit 62 and the first limiting unit 61 are used to place the two ends of the long frame profile 7. By placing the second sliding plate 11 on the slide rail 31, it can be ensured that the first sliding plate 32 and the second sliding plate 11 are on the same motion track, which means that the punching accuracy of the equipment is guaranteed.

[0026] Furthermore, the first limiting unit 61 includes a first limiting block 611 connected to the frame 1, a first clamping cylinder 613 connected to the first limiting block 611, and a first clamping block 612 connected to the power output end of the first clamping cylinder 613; the second limiting unit 62 includes a second limiting block 621, a second clamping cylinder 623 connected to the second limiting block 621, and a second clamping block 622 connected to the second clamping cylinder 623, and the first clamping block 612 and the second clamping block 622 are used to clamp the two ends of the external long frame profile 7.

[0027] In the above design, the first clamping block 612 presses one end of the long frame profile 7 downward through the first clamping cylinder 613, and the second clamping block 622 presses the other end of the long frame profile 7 downward through the second clamping cylinder 623, thereby completing the fixation of the two ends of the long frame profile 7. The first limit block 611 and the second limit block 621 provide support for the first clamping block 612 and the second clamping block 622, making it more stable when clamping the long frame profile 7. Specifically, the first clamping cylinder 613 and the second clamping cylinder 623 are both rotating downward pressing cylinders.

[0028] Furthermore, the first limiting block 611 is provided with a first positioning groove 6111, and the second limiting block 621 is provided with a second positioning groove 6211.

The first positioning groove 6111 and the second positioning groove 6211 are used for positioning the external frame profile 7.

[0029] In this embodiment, the reinforcing ribs of the long frame profile 7 can be placed and positioned through the first positioning groove 6111 and the second positioning groove 6211, and can be placed in the first positioning groove 6111 and the second positioning groove 6211 to prevent the frame profile 7 from having only the reinforcing ribs contacting the limit block and reducing stability due to the reinforcing ribs. That is, the punching accuracy and quality can be improved by the first positioning groove 6111 and the second positioning groove 6211.

[0030] Furthermore, the frame 1 is also provided with a discharge mechanism 12 for discharging waste, and the discharge mechanism 12 includes a plurality of discharge slopes 121 symmetrically connected in pairs.

[0031] Through the above design, when punching the long frame profile 7, the waste generated by the punching will be guided to the bottom of the device through the discharge slope 121, and a collection box can be set at the bottom to collect the waste.

[0032] Preferably, the number of the first pressing cylinder 613 and the number of the second pressing cylinder 623 are both two.
