Description

Technical Field

[0001] This invention relates to the field of CNC punching equipment technology, specifically a CNC punching machine with CNC functions. Background Technology

[0002] A CNC punch press is an automated machine tool equipped with a program control system. This control system can logically process and decode programs with control codes or other symbolic instructions, thereby enabling the punch press to process parts. CNC punch presses can be used for processing various thin metal sheet parts and can automatically complete multiple complex hole shapes and shallow drawing forming processes in one go. CNC punch presses are characterized by high processing accuracy, high rigidity, and high productivity. When performing continuous punching processing on workpieces, CNC punch presses require loading and unloading of workpieces to ensure processing efficiency.

[0003] However, there are still some problems with loading and unloading CNC punch presses: In traditional CNC punch presses, the workpieces are mostly placed into the press by manual loading, which poses certain safety risks. In addition, manual loading cannot ensure the accuracy of the workpiece loading, which can easily affect the quality of subsequent processing of the workpiece. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a CNC punching machine with numerical control functions, which ensures the safety of loading workpieces, avoids injury to workers, and improves the accuracy of loading workpieces.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a CNC punching machine with CNC function, comprising a CNC machine tool body with a processing table, and a feeding mechanism disposed on one side of the CNC machine tool body for conveying workpieces to the processing table. The feeding mechanism includes a support table disposed on one side of the processing table, a storage component disposed on the support table for placing multiple workpieces, a discharging component disposed on the support table and connected to the storage component, and a conveying component disposed on the support table for conveying workpieces to the processing table.

[0006] The feeding assembly includes a second top plate and a first top plate symmetrically arranged on both sides of the conveying assembly and arranged vertically in parallel, a transmission rod whose two ends are respectively rotatably connected to the side of the second top plate near the support platform and the side of the first top plate away from the support platform, and a telescopic rod arranged on the bottom end face of the first top plate away from the transmission rod and on the support platform. The first top plate and the second top plate can rotate around the axis.

[0007] The material storage assembly includes four vertical rods symmetrically arranged in pairs on the support platform, and a limiting plate arranged between adjacent vertical rods on one side of the support platform, with the two limiting plates being parallel to each other; a first top plate and a second top plate are arranged between the two vertical rods and below the limiting plates, and the center positions of the end faces of the first top plate and the second top plate are rotatably connected to the sides of different vertical rods respectively.

[0008] The storage assembly also includes two movable seats that are slidably disposed in movable slots on the top end face of the support platform and on both sides of the conveying assembly, a bidirectional screw rod disposed at the bottom end of the support platform below the vertical rod, and two linkage rods with one end respectively sleeved on the bidirectional screw rod and threadedly connected to the bidirectional screw rod. The linkage rods are U-shaped, and the ends of the linkage rods away from the bidirectional screw rods are respectively fixedly connected to the side of the movable seats.

[0009] A driven gear is fixedly installed in the middle of the bidirectional screw, and the driven gear meshes with the drive gear driven by the motor.

[0010] The conveying assembly includes a push screw installed in a push groove on the top end face of the support platform, a push block sleeved on the push screw and threadedly connected to the push screw, a fixed rod with its bottom end vertically installed on the push block, and a rotating rod with its bottom end rotatably installed in a rotating groove on the side of the fixed rod near the processing table. The side of the rotating rod that passes through the rotating groove is connected to the inner wall of the rotating groove by a torsion spring, and the rotating rod is set in a vertical direction when the torsion spring is in normal condition.

[0011] Rotatable balls are inlaid at equal intervals along the length of adjacent sides of the top surfaces of the two first top plates.

[0012] The beneficial effects of this invention are as follows: Multiple workpieces are placed directly above two second top plates, with the edges of the workpieces pressing against the edges of the two second top plates. When no workpieces are pressed against the adjacent edges of the two first top plates, the workpieces on the second top plates will rotate around the axis under the action of gravity, causing the workpieces on the two second top plates to fall onto the first top plate. At this time, the first top plate is pressed with workpieces. The transmission rod set between the first and second top plates ensures that the second top plate is in a lateral state, preventing the workpieces on the second top plate from moving onto the first top plate. Furthermore, the conveying assembly set on the support platform facilitates the movement of the workpieces on the first top plate onto the processing table, thereby ensuring that the position of the workpieces on the processing table remains consistent. This improves the accuracy of workpiece loading, ensures the safety of workpiece loading, and avoids injury to workers. Attached Figure Description

[0019] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0020] Please see Figure 1-4 A CNC punching machine with CNC function includes a CNC machine tool body 1 with a processing table 2, and a feeding mechanism for conveying workpieces to the processing table 2 from one side of the CNC machine tool body 1. The feeding mechanism includes a support table 3 on one side of the processing table 2, a storage component for placing multiple workpieces on the support table 3, a discharging component on the support table 3 and connected to the storage component, and a conveying component on the support table 3 for conveying the workpieces to the processing table 2.

[0021] The feeding assembly includes a second top plate 19 and a first top plate 18 symmetrically arranged on both sides of the conveying assembly and arranged vertically in parallel; a transmission rod 20 whose two ends are respectively rotatably connected to the side of the second top plate 19 near the support platform 3 and to the side of the first top plate 18 away from the support platform 3; and a telescopic rod 21 arranged on the bottom end face of the first top plate 18 away from the transmission rod 20 and on the support platform 3. The first top plate 18 and the second top plate 19 can rotate around the axis.

[0022] like Figure 1-4 As shown, when placing the workpiece on the processing table 2, multiple workpieces are placed directly above the adjacent edges of the two second top plates 19, so that the edges of the workpieces press against the two second top plates 19. When no workpiece is pressed against the first top plate 18, due to the action of the workpiece, the workpiece on the second top plate 19 will fall onto the first top plate 18 under the rotation of the second top plate 19, causing the workpiece to press against the adjacent edges of the two first top plates 18. At this time, the first top plate 18 will rotate under the action of the workpiece, but the first top plate 18 is equipped with a telescopic rod, thereby preventing the workpiece from falling onto the support table 3 due to the rotation of the first top plate 18, which would cause the surface of the workpiece to be damaged. Damage caused by collision between the surface of the first top plate 18 and the surface of the support platform 3 is prevented. The transmission rod 20 between the first top plate 18 and the second top plate 19 helps to lift the second top plate 19, preventing the workpiece from falling off the second top plate 19 when there is workpiece on the first top plate 18. The conveying assembly on the support platform 3 facilitates the transport of the workpiece from the first top plate 18 to the processing table 2, ensuring that the workpiece is transported to the processing table 2 one by one, ensuring the consistency of the position of the workpiece on the processing table 2 each time, ensuring the safety of workpiece loading, avoiding injury to the workers, and improving the accuracy of workpiece loading.

[0023] The material storage assembly includes four vertical rods 6 arranged symmetrically in pairs on the support platform 3, and a limiting plate 7 arranged between adjacent vertical rods 6 on one side of the support platform 3, with the two limiting plates 7 being parallel to each other; a first top plate 18 and a second top plate 19 are arranged between the two vertical rods 6 and below the limiting plate 7, and the center positions of the end faces of the first top plate 18 and the second top plate 19 are respectively rotatably connected to the side of different vertical rods 6.

[0024] like Figure 1-3 As shown, multiple workpieces are placed directly on two second top plates 19 between two limiting plates 7. The two limiting plates 7 ensure that the position of the multiple workpieces remains unchanged, thereby ensuring that the workpieces on the second top plates 19 can fall steadily one by one onto the first top plate 18, and then be transported one by one to the processing table 2 by the conveying components set on the support platform 3.

[0025] The storage assembly also includes two movable seats 5 that are slidably disposed on the top end face of the support platform 3 and in the movable grooves 4 opened on the two end faces of the conveying assembly, a bidirectional screw 16 disposed at the bottom end of the support platform 3 below the vertical rod 6, and two linkage rods 17 with one end respectively sleeved on the bidirectional screw 16 and threadedly connected to the bidirectional screw 16. The linkage rods 17 are U-shaped, and the ends of the linkage rods 17 away from the bidirectional screw 16 are fixedly connected to the side of the movable seat 5.

[0026] like Figure 1-3 As shown, by controlling the rotation of the bidirectional screw 16, it is easy to adjust the two linkage rods 17 to move closer or further apart. The linkage rods 17 are connected to the movable seat 5, which facilitates the movement of the movable seat 5 within the movable groove 4. This allows for adjustment of the distance between the two limiting plates 7 set on the movable seat 5, thus facilitating the placement of workpieces of different sizes on the second top plate 19 and improving the application range of the feeding device.

[0027] A driven gear 15 is fixedly installed in the middle of the bidirectional screw 16, and the driven gear 15 meshes with the drive gear 14 driven by the motor.

[0028] like Figure 2 As shown, the motor is a stepper motor, which drives the drive gear 14 to rotate, thereby enabling the drive gear 14 to drive the driven gear 15 to rotate, which in turn drives the bidirectional screw 16 to rotate.

[0029] The conveying assembly includes a push screw 9 set in a push groove 8 on the top end face of the support platform 3, a push block 10 sleeved on the push screw 9 and threadedly connected to the push screw 9, a fixed rod 11 vertically set on the push block 10 at its bottom end, and a rotating rod 13 rotatably set in a rotating groove 12 on the side of the fixed rod 11 near the top of the processing table 2 at its bottom end. The side of the rotating rod 13 passing through the rotating groove 12 is connected to the inner wall of the rotating groove 12 by a torsion spring, and the rotating rod 13 is set in a vertical direction when the torsion spring is in normal state.

[0030] like Figure 1-4As shown, the push screw 9 is driven by a motor, which facilitates the movement of the push block 10 within the push groove 8 by controlling the rotation of the push screw 9. The fixed rod 11 and rotating rod 13 on the push block 10 move the workpiece located on the first top plate 18 to the processing table 2. At this time, the workpiece located on the second top plate 19 will fall onto the first top plate 18. The push block 10 returns to its original position under the action of the push screw 9. The rotating rod 13 on the fixed rod 11 will rotate around the connection point with the fixed rod 11, which facilitates the return of the push block 10 to its original position. This ensures the safety of workpiece loading, avoids the dangers that may occur with manual loading, and prevents injury to workers.

[0031] Rotatable balls 22 are inlaid at equal intervals along the length direction on adjacent sides of the top end faces of the two first top plates 18.

[0032] like Figure 1 and Figure 3 As shown, when the workpiece is located on the first top plate 18, the ball bearing 22 contacts the surface of the workpiece. When the workpiece is moved from the first top plate 18 by the conveying assembly, damage to the workpiece is avoided, and the workpiece is made easy to move on the first top plate 18.

[0033] The workpiece can be a steel plate or similar material to be processed.
