Description

Technical Field

[0001] The utility model relates to the technical field of mechanical punches, in particular to a punch mechanism for general machinery. Background Technique

[0002] Stamping is a forming processing method that relies on a press and a die to apply external forces to plates, strips, pipes, profiles, etc., so as to cause plastic deformation or separation, thereby obtaining workpieces (stamped parts) with the required shapes and sizes. Stamping and forging belong to plastic processing (or pressure processing) together, collectively called forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips. Among the steels in the world, 60-70% are plates, and most of them are made into finished products through stamping. The body, chassis, fuel tank, radiator fins of automobiles, the steam drum of boilers, the casing of containers, and the silicon steel sheets of the cores of motors and electrical appliances are all processed by stamping. There are also a large number of stamped parts in products such as instruments, household appliances, bicycles, office machinery, and daily utensils.

[0003] In the existing punch press processing, for punching holes of different sizes during processing, the punch needs to be repeatedly positioned and installed. It is impossible to complete the punching operation on the plate in one installation. Installing a new punch also requires disassembling the existing punch on the punch press. When replacing different punches, it not only wastes time but also reduces work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a punch mechanism for general machinery to solve the problems raised in the above background technique.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: A punch mechanism for general machinery, including a punch press 1, a controller 2 is fixedly installed on the left side of the punch press 1, which can control stamping such as speed and other controls, an output device 3 is fixedly installed on the left side of the punch press 1, which can drive the stamping device 5 to work, a workbench 4 is fixedly installed inside the punch press 1 for convenient processing, a stamping device 5 is fixedly installed inside the punch press 1, which can stamp the workpiece, a replacement mechanism 6 is provided inside the stamping device 5 for convenient replacement of the punch, a cleaning mechanism 7 is provided inside the punch replacement mechanism 6, which can clean the through hole of the punch, and a first punch 8 is fixedly installed at the bottom of the replacement mechanism 6 to stamp the workpiece according to the size of the first punch 8.

[0022] Specifically, the replacement mechanism 6 includes: a mounting head 601, a limiting plate 602, a threaded block 603, a fixing plate 604, a second punch 605, a cylinder 606, and a threaded groove 607. The mounting head 601 is fixedly connected to the inside of the stamping device 5 by bolts, which is convenient for installation on the stamping device 5. The outer wall of the mounting head 601 is fixedly installed with a threaded block 603, which is convenient for the threaded block 603 to be screwed into the threaded groove 607. The outer wall of the mounting head 601 is threadedly connected to the limiting plate 602, which is convenient for preventing the mounting head 601 from continuing to move in the threaded groove 607 when the second punch 605 does not extend or retract, playing a fixing role. There is a fixing plate 604. The bottom of the mounting head 601 is fixedly installed with a fixing plate 604, which is convenient for limiting the second punch 605 and facilitating installation. The bottom of the fixing plate 604 is fixedly connected to the second punch 605, which can be easily replaced. The outer wall of the mounting head 601 is attached to the cylinder 606, which is convenient for installing the second punch 605. The inner wall of the cylinder 606 is provided with a threaded groove 607, which is convenient for fixing the mounting head 601 in the cylinder 606. The threaded block 603 on the outer wall of the mounting head 601 is threadedly connected to the threaded groove 607 on the inner wall of the cylinder 606, enabling the mounting head 601 to rotate and enter the cylinder 606 through the threaded block 603.

[0023] Specifically, the cleaning mechanism 7 includes: a telescopic rod 701, a spring 702, and a disc 703. The telescopic rod 701 is fixedly installed at the bottom of the fixing plate 604, which is convenient for the telescopic rod 701 to be compressed when the mounting head 601 is screwed in, so that the disc 703 is at the bottom of the cylinder 606. One end of the telescopic rod 701 away from the bottom of the fixing plate 604 is fixedly installed with a disc 703, which is convenient for taking out the iron filings and residues in the through hole. The disc 703 is slidably connected to the outer wall of the second punch 605 and the inside of the cylinder 606. The spring 702 is fixedly installed at the bottom of the fixing plate 604, which is convenient for the telescopic rod 701 to reset. The telescopic rod 701 and the spring 702 are arranged in a circumferential array centered on the fixing plate 604, with two groups provided, which can better pull out the disc 703 evenly. One end of the spring 702 away from the fixing plate 604 is fixedly connected to the disc 703, which is convenient for pulling out the disc 703.

[0024] Working principle: When it is necessary to adjust punches of different sizes during stamping, by rotating the mounting head 601, the threaded block 603 on the mounting head 601 rotates into the threaded groove 607 in the cylinder 606, and then rotating the limit plate 602 to fix the mounting head 601, and the second punch 605 and the bottom of the first punch 8 are on the same horizontal plane, which is convenient for stamping. By tightening the bolts inside the stamping device 5, the mounting head 601 can be clamped on the stamping device 5, enabling the first punch 8 to stamp the workpiece. When replacement is needed, rotate the limit plate 602 on the mounting head 601 to the top of the threaded block 603, and then continue to rotate the mounting head 601 to make it continue to rotate in the threaded groove 607, and the fixing plate 604 at the bottom of the mounting head 601 moves downward, driving the second punch 605 to move downward, so that the second punch 605 extends out of the bottom of the first punch 8, and thus the second punch 605 can be used for stamping. The operation is convenient and the work efficiency can be improved.

[0025] After the second punch 605 is used and needs to be disassembled, there will be residues such as iron filings at the through hole of the first punch 8. Rotate the mounting head 601 to make the threaded block 603 on the mounting head 601 rotate out of the threaded groove 607, and the second punch 605 will bring out the iron filings and residues on the surface and at the through hole of the first punch 8 into the cylinder 606. Pulling out the telescopic rod 701 will drive the disc 703 to be pulled out, so that the iron filings and residues on the second punch 605 fall on the disc 703. After the disc 703 is pulled out, the through hole of the first punch 8 can be cleaned, and then the telescopic rod 701 is reset by the spring 702, so that the disc 703 can directly reach the bottom of the cylinder 606 during the next installation, which is convenient for the next use and prevents jamming during installation.

[0026] The above text has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
