Description

Technical Field

[0001] This utility model belongs to the field of CNC punching technology, and in particular relates to a CNC punching machine with automatic loading and unloading. Background Technology

[0002] CNC punch press, short for numerical control punch press, 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, decode them, and thus enable the punch press to move and process parts.

[0003] The utility model disclosed in CN212525742U is a CNC punch press with automatic loading and unloading, including two gantry supports and a CNC punch press body. A material conveying mechanism is provided between the gantry supports and the CNC punch press body. The lower ends of the two support legs of the gantry supports are fixedly connected to bases. The upper ends of the two gantry supports are fixedly connected to two parallel crossbeams, which are perpendicular to the gantry supports. Electric slide rails are provided on the side walls of the crossbeams, and electric sliders are slidably connected in the electric slide rails. The lower ends of the electric sliders are fixedly connected to two first electric push rods.

[0004] In the aforementioned application document, the lateral position of the material clamping structure can be adjusted by using electric slide rails and electric sliders, and the longitudinal position of the material clamping structure can be adjusted by using the first electric push rod. The further material clamping mechanism can clamp the material and then complete the material conveying. However, the process of feeding the material into the main body of the CNC punch press is relatively troublesome and can easily affect the use of the main body of the CNC punch press, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a CNC punching machine with automatic loading and unloading, which solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic loading and unloading CNC punch press, comprising a CNC punch press body, a conveying device, and a support column. A punching device is mounted on the top of the CNC punch press body. A fixed frame is fixedly connected to the top of the support column, and a loading and unloading mechanism is mounted on the top of the fixed frame. The loading and unloading mechanism includes a fixed base, a groove on the top of the fixed base, a slide block slidably connected inside the groove, a threaded rod A rotatably connected inside the slide block, a moving motor fixedly mounted at the rear end of the fixed base, a hydraulic cylinder fixedly mounted at the bottom of the slide block, a connecting frame fixedly connected to the output end of the hydraulic cylinder, a slide rod fixedly connected to the inner side of the groove, a clamping plate slidably connected to the surface of the slide rod, a threaded rod B rotatably connected to the inner side of the groove, a clamping motor fixedly mounted on the outer side of the connecting frame, and a warning mechanism on the top of the slide block.

[0008] Furthermore, the output shaft of the mobile motor is fixedly connected to the threaded rod A, and the slide is threadedly connected to the threaded rod A through the built-in thread. When the mobile motor is turned on, the mobile motor will drive the threaded rod A to rotate through its output shaft. The rotation of the threaded rod A will drive the slide to move along the slide groove to the front end or the rear end through the engagement of the threads.

[0009] Furthermore, the clamping motor is fixedly connected to the threaded rod B via its output shaft, and the clamping plate is threadedly connected to the threaded rod B via its internal threads. When the clamping motor is turned on, the clamping motor will drive the threaded rod B to rotate via its output shaft. The rotation of the threaded rod B will drive the clamping plate to move laterally along the slide bar through the engagement of the threads.

[0010] Furthermore, two-thirds of the clamping plate protrudes from the front end of the connecting frame, and the connecting frame is located directly behind the main body of the CNC punching machine. When the clamping plate protrudes from the connecting frame to clamp the item and transport it to the main body of the CNC punching machine, the connecting frame will not collide with the stamping device.

[0011] Furthermore, the warning mechanism includes a rotating rod, a gear, and a bell. The rotating rod is rotatably connected to the top of the slide, a rotating gear is fixedly connected to the top of the rotating rod, a collision rod is fixedly connected to the surface of the rotating rod, the gear is fixedly connected to the top of the fixed base, and the bell is fixedly installed on the top of the slide.

[0012] Furthermore, the teeth on the rotating gear mesh with the teeth on the rack, and the length of the rack is greater than the length of the slide groove. When the slide moves back and forth, the rotating gear will rotate due to the meshing of the rotating gear and the rack.

[0013] Furthermore, the length of the collision rod is greater than the distance from the surface of the rotating rod to the bell, and the collision rod is made of rubber. When the collision rod rotates with the rotating rod, it will repeatedly strike the bell. The rubber collision rod is elastic and will not damage the bell.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a loading and unloading mechanism, achieves the following when it is necessary to transport items on the conveyor belt to the main body of the CNC punch press: the moving motor can be turned on to drive the threaded rod A to rotate, which can make the slide move to the front or rear end, the hydraulic cylinder can be turned on to drive the connecting frame to rise or fall, and the clamping motor can be turned on to drive the two sets of clamping plates to come closer together to clamp the items, forming a cooperation to transport the items to the main body of the CNC punch press, without conflicting with the stamping device on the top of the CNC punch press.

[0016] 2. This utility model, by setting up a warning mechanism, achieves the following: when the moving motor drives the threaded rod A to rotate, causing the slide to move to the front or rear, the rotating gear, rack, and other components will work together to cause the collision rod to repeatedly strike the bell, making the bell ring and reminding people around to stay away.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A clamping motor 511 is fixedly installed on the outer side of the connecting frame 57. A warning mechanism 7 is provided on the top of the slide block 53.

[0028] The output shaft of the moving motor 55 is fixedly connected to the threaded rod A54. The slide 53 is threadedly connected to the threaded rod A54 through its internal thread. When the moving motor 55 is turned on, the moving motor 55 will drive the threaded rod A54 to rotate through its output shaft. The rotation of the threaded rod A54 will drive the slide 53 to move along the slide groove 52 to the front end or the rear end through the engagement of the threads.

[0029] The clamping motor 511 is fixedly connected to the threaded rod B510 via its output shaft. The clamping plate 59 is threadedly connected to the threaded rod B510 via its internal thread. When the clamping motor 511 is turned on, the clamping motor 511 will drive the threaded rod B510 to rotate via its output shaft. The rotation of the threaded rod B510 will drive the clamping plate 59 to move laterally along the slide bar 58 through the engagement of the threads.

[0030] Two-thirds of the clamping plate 59 protrudes from the front end of the connecting frame 57, and the connecting frame 57 is located directly behind the main body 1 of the CNC punching machine. When the clamping plate 59 protrudes from the connecting frame 57 to clamp the item and transport it to the main body 1 of the CNC punching machine, the connecting frame 57 will not collide with the stamping device 6.

[0031] The warning mechanism 7 includes a rotating rod 71, a rack 74, and a bell 75. The rotating rod 71 is rotatably connected to the top of the slide 53.

The hydraulic cylinder 56 is turned on to drive the connecting frame 57 to rise or fall. The clamping motor 511 is turned on. The clamping motor 511 drives the threaded rod B510 to rotate through its output shaft. The rotation of the threaded rod B510 drives the clamping plate 59 to move laterally along the slide rod 58 through the engagement of the threads. Two sets of clamping plates 59 move close together to clamp the item, thus forming a cooperation to transport the item to the main body 1 of the CNC punch press, without conflicting with the stamping device 6 on the top of the CNC punch press body 1. As the threaded rod A54 rotates, the slide block 53 moves along the slide groove 52 to the front or rear. The rotating gear 72 meshes with the rack 74 and rotates. The rotation of the rotating gear 72 drives the rotating rod 71 to rotate, and the rotation of the rotating rod 71 drives the collision rod 73 to rotate. When the collision rod 73 rotates with the rotating rod 71, it will repeatedly hit the bell 75. The rubber collision rod 73 is elastic and will not damage the bell 75.
