Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a punching device for hardware processing. Background Art

[0002] Hardware processing is the process of processing raw materials into various parts according to customer drawings or samples using lathes, milling machines, drilling machines, polishing machines and other machines, such as screws, motor shafts, model car parts, fishing gear accessories, speaker product casings, mobile power casings, etc. Punching devices are often required in hardware processing.

[0003] After searching, the patent number is CN217860161U, which discloses a punching device for hardware processing. The threaded vertical rod is driven to rotate by rotating the handle. The threaded vertical rod cooperates with the thread of the connecting horizontal plate. At the same time, the clamping plate cooperates with the sliding of the connecting vertical rod. The rotation of the threaded vertical rod drives the clamping plate to move downward along the vertical rod until the clamping plate presses and fixes the hardware to be punched on the table. The two hardware clamping mechanisms cooperate to clamp and fix the two ends of the hardware, thereby reducing the problem of deviation in punching caused by displacement of the hardware during punching. However, when using the punching device for hardware processing, it can only punch the hardware in a single direction. Generally, the hardware needs to be frequently moved to punch, which has great limitations. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a punching device for hardware processing. The existing punching device for hardware processing can only perform a punching operation on the hardware in a single direction when in use, and generally requires the hardware to be frequently moved to perform the punching, which has great limitations.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a punching device for hardware processing, comprising a main body, and also comprising a first slot shell and a second slot shell, wherein a first slider and a limit block are respectively arranged inside the first slot shell and the second slot shell, and the upper surfaces of the first slider and the limit block are fixedly connected with connecting vertical rods, and a top slot shell is clamped between the upper ends of the two groups of connecting vertical rods, and a second slider is arranged inside the top slot shell, and a hydraulic cylinder is clamped at the lower end of the second slider, and a punching drill rod is fixedly connected to the output end of the hydraulic cylinder.

[0006] As a further solution of the utility model: the first trough shell and the second trough shell are both fixedly connected to the main body, a first screw rod is penetrated through the first trough shell, and the first sliding block is threadedly connected to the first screw rod.

[0007] As a further solution of the utility model: the interior of the second tank shell is clamped with a limit rod, and the limit block is slidably connected to the limit rod.

[0008] As a further solution of the utility model: a second screw rod is provided through the top tank shell, and the second sliding block is threadedly connected to the second screw rod.

[0009] As a further solution of the utility model: a fixed sleeve is fixedly sleeved on the outer side of the punching drill rod, a buffer ring plate is arranged below the punching drill rod, four groups of fixed plates are fixedly connected to the outer side of the buffer ring plate, and the upper surfaces of the four groups of fixed plates are fixedly connected to limiting sliding rods.

[0010] As a further solution of the utility model: the four groups of limit sliding rods are symmetrically arranged about the punching drill rod, and the four groups of limit sliding rods are all slidably connected to the fixed sleeve.

[0011] As a further solution of the utility model: the outer sides of the four groups of limit sliding rods are all sleeved with buffer springs, and the four groups of buffer springs are all located at the lower side of the fixed sleeve.

[0012] As a further solution of the utility model: four groups of screw rings are arranged above the fixed sleeve near the edge, and the four groups of screw rings are respectively threadedly connected to the four groups of limiting sliding rods.

[0013] The utility model adopts the above technical scheme, and has the following advantages compared with the prior art: by rotating the first screw on the first slot shell, the first slider is driven to move along the inner side of the first slot shell, so that the two groups of connecting vertical rods are driven to move longitudinally together through the limit block cooperating with the limit rod in the second slot shell, thereby driving the top slot shell to move longitudinally, and then rotating the second screw on the top slot shell to drive the second slider to move along the inner side of the top slot shell, thereby driving the punching drill rod to move horizontally, and punching operations can be performed on various positions on the surface of the hardware without frequently moving the hardware, and it has good applicability.

[0014] First, the buffer ring plate is made to fit with the upper surface of the hardware. As the punching drill rod moves downward continuously, the fixed sleeve is driven to move downward continuously. At this time, the limit sliding bars on the upper sides of the four sets of fixed plates are respectively slidably connected with the fixed sleeves, so that the four sets of buffer springs are continuously compressed, thereby increasing the fit strength between the buffer ring plate and the hardware, and avoiding relative displacement between the punching drill rod and the hardware during the punching process, thereby significantly improving the punching stability of the hardware.

[0025] In this embodiment, the second screw rod 10 is threadedly connected to the second sliding block 11 so as to facilitate the movement of the hydraulic cylinder 12 .

[0026] Specifically, by rotating the first screw rod 4 on the first groove shell 2 to drive the first slider 6 to move along the inner side of the first groove shell 2, the two sets of connecting vertical rods 8 are driven to move longitudinally together through the limit block 7 in cooperation with the limit rod 5 in the second groove shell 3, thereby driving the top groove shell 9 to move longitudinally, and then rotating the second screw rod 10 on the top groove shell 9 to drive the second slider 11 to move along the inner side of the top groove shell 9, thereby driving the punching drill rod 13 to move laterally, and punching operations can be performed at various positions on the surface of the hardware without frequently moving the hardware, and it has good applicability.
