Description

Technical Field

[0001] This utility model relates to the field of CNC punching technology, and in particular to a CNC punching machine with an automatic feeding and correction mechanism. Background Technology

[0002] CNC punching machines are automated machine tools that use digital control technology as their core and automatically complete punching, tapping, creasing, and cutting processes through preset programs. They process coded or symbolic instructions through the CNC system and automatically select tools to perform multi-process processing on metal sheets, supporting processes such as shallow drawing, louvers, and countersunk holes for complex shapes.

[0003] When machining planar parts, a CNC punch press is needed to precisely cut the contours of the parts. During the machining process, the workpiece needs to be placed on the worktable manually or by a robotic arm, and then fed under the die head for processing. However, since the position of the workpiece on the worktable may vary, it is necessary to adjust its position before machining to ensure alignment with the die head. This adjustment operation after unloading significantly delays the entire machining process and increases the processing time. Therefore, we propose a CNC punch press with an automatic feeding and correction mechanism. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example Reference Figures 1-4 A CNC punch press with an automatic feeding and correction mechanism includes a base 1. A punch press 31 is arranged above the base 1. The punch press 31 is arranged on the bottom of a lifting mechanism 32, and the lifting mechanism 32 is fixed to the base 1 through a connecting frame 33. In actual use, the lifting mechanism 32 is one of an electric push rod, a hydraulic cylinder, or a pneumatic cylinder, which can drive the punch press 31 to move up and down above the base 1.

[0019] Specifically, such as Figure 1As shown, a control box 34 is provided on one side of the base 1. A support base 30 is installed at the bottom of the control box 34. A controller is installed inside the control box 34. The controller is connected to the punch press 31 and the lifting mechanism 32 through wires. In actual use, the controller is one of a PLC logic controller, a control motherboard, or a control host. In addition, a touch screen display is also provided on the outer wall of the control box 34. The touch screen display is connected to the controller through wires to control the punch press 31.

[0020] like Figure 1 As shown, a strip seat 2 is installed on the top of the base 1, and a linear motor 3 is correspondingly installed on the top of the strip seat 2. The linear motor 3 is connected to the controller through wires. The slide rail of the linear motor 3 is fixed on the strip seat 2, and a strip-shaped housing 4 is installed on the slider of the linear motor 3. The length direction of the housing 4 is perpendicular to the length direction of the strip seat 2, so that the housing 4 moves linearly above the strip seat 2.

[0021] like Figure 2 and Figure 3 As shown, a strip groove 15 extending along the length of the housing 4 is formed on the top of the housing 4. A lead screw 16 is provided on one side inside the housing 4, with its end rotatably connected to the inner wall of the housing 4. A drive motor 17 is mounted on one end of the lead screw 16 and is fixed to the outer wall of the housing 4. The drive motor 17 is connected to a controller via a wire. A movable seat 19 is threaded onto the lead screw 16 via a nut. The movable seat 19 is connected to a support plate 22 via a first support frame 20. The top of the support plate 22 passes through the strip groove 15 and... A feeding plate 23 is connected, and the bottom of the feeding plate 23 is in clearance fit with the top surface of the housing 4. In actual use, the feeding plate 23 is located at one end of the housing 4. Under the operation of the drive motor 17, the feeding plate 23 can be moved from one end of the housing 4 to the other end of the housing 4. That is, when in use, the parts to be processed can be placed at the end of the housing 4 close to the feeding plate 23. As the feeding plate 23 moves and acts on the parts, it can push the parts to move to the bottom of the punch press processor 31 for processing, thus completing the feeding operation of the parts.

[0022] Furthermore, the drive motor 17 is housed inside the motor housing 18, which is fixed to the outer wall of the housing 4, thus protecting the drive motor 17.

[0023] Furthermore, such as Figure 3 and Figure 4As shown, a first guide shaft 24 is provided on the side of the housing 4 away from the lead screw 16. The end of the first guide shaft 24 is fixed to the inner wall of the housing 4. A sliding sleeve 25 is slidably installed on the first guide shaft 24. The outer wall of the sliding sleeve 25 is connected to the support plate 22 through the second support frame 21 to guide the movement of the feeding plate 23 above the housing 4, improve the movement stability of the feeding plate 23, and allow the feeding plate 23 to move smoothly in a straight line above the housing 4.

[0024] like Figure 2 and Figure 3 As shown, after the feeding plate 23 pushes the parts to the bottom of the punch press 31, a fixed seat 5 is installed in the middle of both sides of the machine housing 4. The two fixed seats 5 are provided with parallel clamping plates 6 on the side that is relatively close to each other. A pushing mechanism 7 is vertically installed in the middle of the side that is relatively far apart from each other. The pushing mechanism 7 is fixed on the fixed seat 5 and is connected to the controller through a wire. In actual use, the pushing mechanism 7 is one of an electric push rod, a hydraulic cylinder, or a pneumatic cylinder. The two clamping plates 6 can be relatively far apart or close together above the machine housing 4 so as to clamp and fix the parts according to the size of the parts to be processed, thereby improving the adaptability of the clamping plates 6 to fix the parts.

[0025] Furthermore, at least one second guide shaft 8 is provided parallel to the side of the pushing mechanism 7. One end of the second guide shaft 8 is fixed to the clamping plate 6, and the other end of the second guide shaft 8 slides through the fixed seat 5 to guide the movement of the clamping plate 6, so that the clamping plate 6 can always maintain a stable linear movement.

[0026] During the process of the feeding plate 23 pushing the parts to the bottom of the punch press 31, a push plate 12 is provided at one end of the clamping plate 6 near the fixed seat 5. Vibration motors 13 are installed on the relatively far sides of the two push plates 12. The vibration motors 13 are connected to the controller via wires. The ends of the push plates 12 are mounted on connecting seats 9, and connecting shafts 10 are installed at both the upper and lower ends of the connecting seats 9. The other end of the connecting shaft 10 is fixed to the connecting plate, and the connecting plate is fixed to the clamping plate 6. A torsion spring 11 is sleeved on the connecting shaft 10. One end of the torsion spring 11... One end is fixed to the connecting plate, and the other end of the torsion spring 11 is fixed to the connecting seat 9. The push plate 12 will swing back and forth at the end of the clamping plate 6 with the connecting shaft 10 as the axis under the operation of the vibration motor 13. This allows the push plate 12 to act on the side of the part, thereby pushing the part closer to the middle between the two clamping plates 6. This ensures that the part is in full contact with the feeding plate 23 and that the part falls stably between the two clamping plates 6 during feeding, preventing the part from shifting and falling between the two clamping plates 6 during feeding, which would affect the subsequent processing progress.

[0027] Specifically, the reciprocating oscillation of the push plate 12 enables the correction of the parts, eliminating the need for manual adjustment of the parts' positions and allowing the parts to be corrected during the feeding process, further saving processing time and improving the processing efficiency of the parts.

[0028] It should be noted that when the push plate 12 swings back and forth, the clamping plates 6 can move closer to each other in advance as the parts enter the push plate 12, so as to further save the processing time. In order to prevent the push plate 12 from swinging too much and applying too much pushing force to the parts, causing damage to the parts or the push plate 12, a baffle 14 is provided at the end of the two push plates 12 that are close to each other. The baffle 14 is fixed to the end of the clamping plate 6 to limit the swing of the push plate 12, so as to prevent excessive squeezing force from causing damage to the parts or the push plate 12.

[0029] During the processing, such as Figure 3 and Figure 4 As shown, guide plates 26 are installed on both sides of the bottom of the strip groove 15. The bottom of the guide plates 26 is bent towards the support plate 22. A strip-shaped guide seat 28 is provided at the bottom inside the housing 4. The top two ends of the guide seat 28 are inclined downwards. Waste discharge ports 29 corresponding to the guide seats 28 are opened at both ends of the housing 4. Limiting plates 27 are installed on both sides of the guide seats 28. The frontal projection of the guide plate 26 is located between the two limiting plates 27. Waste debris falling from the strip groove 15 into the housing 4 will fall onto the guide seat 28 along the guide plate 26 and be discharged from the waste discharge port 29 along the inclined surface of the guide seat 28. This reduces the probability of waste debris adhering to the lead screw 16 after falling into the housing 4, so as to prevent it from hindering the normal function of the lead screw 16.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
