[0001] This utility model relates to the field of CNC punching technology, specifically a punching machine with high stability. Background Technology

[0002] CNC punch press is short for numerical control punch press. It is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, and decode them, so that the punch press can move and process parts. However, with the advancement of science and technology, people have higher and higher requirements for the functions of CNC punch press.

[0003] The Chinese Patent Network discloses a highly stable CNC punching machine, publication number CN219443046U. Although the slider and slide rail are designed so that the slider slides on the slide rail when the slide column moves, and the punch head moves up and down, making the punch head more stable and thus improving the stability of the CNC punching machine, the base in this prior art lacks a corresponding fixing structure. Since the punch head will vibrate when punching the workpiece, the vibration may affect the overall stability, thereby affecting the punching efficiency and accuracy of the workpiece.

[0004] Therefore, a punch press with high stability is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0030] Please see Figure 1 , 2 This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A highly stable punch press, comprising: a worktable 1; a punch press body 2 mounted on the top of the worktable 1; a sliding column 3 mounted on the punch press body 2, and a punching head 4 fixed at the bottom of the sliding column 3; a connecting lug 5 fixed on the outer wall of the worktable 1, the worktable 1 being connected to an external mounting base via the connecting lug 5 and a fixing bolt 6; a movable cavity 7 opened on the outer wall of the worktable 1, a movable block 9 movably disposed within the movable cavity 7, a limiting strip 10 fixed on the outer wall of the movable block 9 abutting against the fixing bolt 6, a through groove 8 communicating with the movable cavity 7 opened on the outer wall of the worktable 1, a threaded actuating rod 11 movably passing through the through groove 8 fixed on the outer wall of the movable block 9, and a fixing ring 12 threadedly connected to the outer wall of the threaded actuating rod 11 abutting against the outer wall of the worktable 1.

[0031] Specifically, since the worktable 1 is connected to the external mounting base using the connecting lug 5 and the fixing bolt 6, the worktable 1 is fixed to the external mounting base. Therefore, when the punch head 4 performs punching work, the worktable 1 and the punch press body 2 will not vibrate synchronously, resulting in high overall stability and ensuring the punching efficiency and accuracy of the workpiece.

[0032] By driving the fixed ring 12 to move on the outer wall of the threaded actuating rod 11, when one end of the fixed ring 12 abuts against the outer wall of the worktable 1, the movable block 9 can be fixed inside the movable cavity 7. Since the outer wall of the movable block 9 is fixed with a limiting strip 10 that abuts against the fixing bolt 6, the limiting strip 10 can limit the fixing bolt 6 to prevent it from loosening, thereby improving the connection stability between the worktable 1 and the external mounting base, further improving the overall stability, and ensuring the stamping efficiency and accuracy of the workpiece. Example 2

[0033] Please see Figure 1 , 3 -5. This utility model provides a technical solution: a highly stable punch press, wherein a limit rod 13 is fixed on the punch press body 2, a limit ring 14 is fixed on the outer wall of the slide column 3 and is movably disposed on the outer wall of the limit rod 13, a connecting sleeve 15 is fixed on the punch press body 2, the limit rod 13 and the limit ring 14 are located inside the connecting sleeve 15, an oil tank 16 is installed on the outer wall of the connecting sleeve 15, the oil tank 16 is filled with lubricating oil, an oil pump 17 is installed inside the oil tank 16, and a connecting pipe 18 is installed at the outlet of the oil pump 17, which passes through the oil tank 16 and the connecting sleeve 15. One end of the connecting pipe 18 is fitted with an annular pipe 19, which is installed on the outer wall of the limiting rod 13. The inner wall of the annular pipe 19 has a leakage hole 20. The connecting sleeve 15 is equipped with a recycling component, which includes a connecting ring 21 connected inside the connecting sleeve 15. A recycling container 23 is fixed to the inner wall of the connecting ring 21, and a knob 22 is fixed to the outer wall of the connecting ring 21. The outer wall of the connecting ring 21 is provided with an external thread, and the inner wall of the connecting sleeve 15 is provided with an internal thread. The connecting ring 21 is threaded inside the connecting sleeve 15 by the external thread and the internal thread.

[0034] Specifically, by starting the oil pump 17, the lubricating oil inside the oil tank 16 will enter the annular pipe 19 through the connecting pipe 18, and then flow to the outer wall of the limiting rod 13 through the leakage hole 20, so as to lubricate the limiting rod 13 and the limiting ring 14, reduce the friction of the limiting rod 13 and the limiting ring 14, and avoid excessive friction of the limiting rod 13 and the limiting ring 14 from affecting the stability of the sliding column 3 and the stamping head 4, thereby improving the overall stability.

[0035] Since a connecting ring 21 is connected inside the connecting sleeve 15, and a recycling container 23 is fixed on the inner wall of the connecting ring 21, the recycling container 23 can recycle and store the dropped lubricating oil, so that the lubricating oil can be reused, which is more energy-saving and environmentally friendly.

[0036] Since the connecting ring 21 is connected to the inside of the connecting sleeve 15 by using the external thread and the internal thread, the connecting ring 21 can be rotated in the opposite direction of the internal thread and the external thread by using the knob 22 to disassemble the connecting ring 21 and the recovery container, thereby facilitating the recycling and reuse of the lubricating oil inside the recovery container 23.

[0037] Working principle:

[0038] Since the worktable 1 is connected to the external mounting base via connecting ears 5 and fixing bolts 6, the worktable 1 is fixedly connected to the external mounting base. Therefore, when the punch head 4 performs punching work, the worktable 1 and the punch press body 2 will not vibrate synchronously, resulting in high overall stability and ensuring the punching efficiency and accuracy of the workpiece. By driving the fixed ring 12 to move on the outer wall of the threaded actuating rod 11, when one end of the fixed ring 12 abuts against the outer wall of the worktable 1, the movable block 9 can be fixed inside the movable cavity 7. Since the outer wall of the movable block 9 is fixed with a limit that abuts against the fixing bolt 6, The limiting strip 10 can limit the fixing bolt 6 to prevent it from loosening, thereby improving the connection stability between the worktable 1 and the external mounting base, further enhancing the overall stability, and ensuring the stamping efficiency and precision of the workpiece. Before installing and removing the fixing bolt 6, the fixing ring 12 is first moved on the outer wall of the threaded actuating rod 11. After one end of the fixing ring 12 is not in contact with the outer wall of the worktable 1, the threaded actuating rod is used in conjunction with the slot 8 to drive the movable block 9 to move in the movable cavity 7. The movable block 9 will drive the limiting strip 10 to move. When the limiting strip 10 is not in contact with the fixing bolt 6, it avoids the limiting strip 10 affecting the disassembly and installation of the fixing bolt 6. By starting the oil pump 17, the lubricating oil inside the oil tank 16 will enter the annular pipe 19 through the connecting pipe 18, and then flow to the outer wall of the limiting rod 13 through the leakage hole 20, so as to lubricate the limiting rod 13 and the limiting ring 14, reduce the friction of the limiting rod 13 and the limiting ring 14, and avoid excessive friction of the limiting rod 13 and the limiting ring 14, which would affect the stability of the sliding column 3 and the stamping head 4, thereby improving the overall stability. Because a connecting ring 21 is connected inside the connecting sleeve 15, and a recycling container 23 is fixed on the inner wall of the connecting ring 21, the recycling container 23 can collect and store the dropped lubricating oil, so that the lubricating oil can be reused, which is more energy-saving and environmentally friendly. Since the connecting ring 21 is connected to the inside of the connecting sleeve 15 by using the external thread and the internal thread, the connecting ring 21 can be rotated in the opposite direction of the internal thread and the external thread using the knob 22, so that the connecting ring 21 and the recycling container can be disassembled, thereby facilitating the recycling and reuse of the lubricating oil inside the recycling container 23.
