Description

Technical Field

[0001] This application relates to the field of standard parts processing technology, and in particular to an auxiliary tooling for a benchtop precision press. Background Technology

[0002] A benchtop precision press is a type of mechanical equipment that applies controllable, vertically downward pressure to complete small-scale, high-precision pressing, stamping, riveting, forming, and other processes. It is characterized by its compact size, ease of operation, low noise, and high precision, and is suitable for light industries such as electronics, instruments, watches, and jewelry.

[0003] Existing benchtop stamping machines generally include a worktable, a stamping head that moves vertically on the worktable, and a moving mechanism for controlling the movement of the stamping head. Additionally, they are equipped with a lower die with a machining groove on its top. During processing, the worker first places the workpiece into the machining groove; then, the lower die is placed on the worktable with the workpiece directly below the stamping head. The moving mechanism then controls the stamping head to move downwards, performing the stamping process on the workpiece.

[0004] During the processing, the workpiece needs to be stamped multiple times by the stamping head. Placing the workpiece in the processing groove can only achieve preliminary positioning. If the gap between the workpiece and the processing groove is too large, the workpiece may move or tilt in the processing groove at the moment the stamping head contacts the workpiece, resulting in inconsistent positions for each processing, large fluctuations in product size, and extremely low yield. Utility Model Content

[0005] In order to improve the problems of inaccurate positioning, easy workpiece displacement and tilting, and low product yield caused by the excessive gap between the machining groove and the workpiece in the existing lower die, this application provides an auxiliary tooling for a benchtop precision press.

[0006] This application provides an auxiliary tooling for a benchtop precision press, employing the following technical solution:

[0007] An auxiliary tooling for a benchtop precision press includes a worktable, a punch head that is movably mounted on the worktable, a moving mechanism for controlling the movement of the punch head, and a lower die mounted on the worktable. The lower die includes a base and a positioning cylinder coaxially mounted on the base. The positioning cylinder is provided with positioning bolts spaced radially therefrom. There are at least three positioning bolts located on the same horizontal plane. By tightening the positioning bolts, the ends of the positioning bolts can be inserted into the positioning cylinder to press against the workpiece. A pressure-bearing component is embedded in the top of the base.

[0008] Preferably, the hardness of the pressure-bearing component is greater than that of the chassis, and the upper surface of the pressure-bearing component constitutes the bearing bottom surface of the lower mold.

[0009] Preferably, the pressure-bearing component is elongated, with both ends extending to the sidewalls of the chassis.

[0010] Preferably, the pressure-bearing component is one of a stainless steel bar, a cemented carbide block, or a ceramic block.

[0011] Preferably, the positioning cylinder is provided with a connecting ring, which is detachably connected to the chassis by bolts and nuts. During installation, the bottom of the nut is flush with the bottom of the chassis.

[0012] Preferably, the positioning cylinder is slidably coaxially provided with a protective cylinder, the protective cylinder is located above the positioning bolt, and a locking element is provided between the protective cylinder and the positioning cylinder. During processing, the top of the protective cylinder is located above the top of the positioning cylinder.

[0013] Preferably, the locking element includes a first magnet disposed on the side wall of the positioning cylinder, a groove formed inside the protective cylinder, and a second magnet disposed at the bottom of the groove. The first magnet is slidably connected to the groove, and the first magnet and the second magnet have opposite magnetic properties. When the first magnet and the second magnet attract each other, the top of the protective cylinder is located above the top of the positioning cylinder.

[0014] In summary, this application includes at least one of the following beneficial effects:

[0015] 1. This application achieves active and precise center positioning of the workpiece by using at least three radial positioning bolts located on the same horizontal plane, which can effectively eliminate the radial gap between the workpiece and the positioning cylinder, prevent the workpiece from moving or tilting during the stamping process, and ensure the repeatability of positioning accuracy for multiple stampings, thereby significantly improving the dimensional consistency and yield of the product.

[0016] 2. In addition, the pressure-bearing components embedded in the top of the chassis (especially high-hardness stainless steel strips, hard alloy blocks, etc.) can effectively disperse the concentrated stress applied by the stamping head, prevent the chassis from being crushed or plastically deformed, greatly improve the durability and service life of the lower die, and ensure positioning stability under long-term use.

[0017] 3. By setting a sliding protective cylinder with magnetic locking on the positioning cylinder, it can not only prevent debris from flying around during processing and ensure the safety of the auxiliary tooling of this application, but also allow the protective cylinder to slide down after stamping is completed, making it convenient for manual removal of the workpiece from the positioning cylinder.

[0029] Furthermore, the lower mold 3 includes a base 31 and a positioning cylinder 32 coaxially mounted on the base 31. A connecting ring 321 is fixed to the side wall of the positioning cylinder 32 near its bottom. The connecting ring 321 is detachably connected to the base 31 by bolts and nuts. During installation, the bottom of the nut is flush with the bottom of the base 31. The detachable connection between the positioning cylinder 32 and the base 31 via the connecting ring 321 allows for the individual replacement or repair of the positioning cylinder 32, reducing operating costs and improving the adaptability of auxiliary tooling.

[0030] Furthermore, the positioning cylinder 32 is provided with adjustable positioning bolts 4 at radial intervals, and the positioning bolts 4 are threaded onto the positioning cylinder 32. In this embodiment, three positioning bolts 4 are used, all located on the same horizontal plane. By screwing the positioning bolts 4, their ends can be inserted into the positioning cylinder 32 to press against the workpiece. By using at least three points that are not on the same straight line (forming a surface) to actively and adjustably center the workpiece from the side, radial clearance can be effectively eliminated, and precise centering can be achieved.

[0031] A pressure-bearing component 5 is embedded in the top of the chassis 31. The hardness of the pressure-bearing component 5 is greater than that of the chassis 31, and the upper surface of the pressure-bearing component 5 forms the bearing bottom surface of the lower mold 3. The pressure-bearing component 5 is elongated, with both ends extending to the side walls of the chassis 31. In this embodiment, the pressure-bearing component 5 is made of stainless steel strip. Alternatively, the pressure-bearing component 5 can also be made of hard alloy block or ceramic block.

[0032] The positioning cylinder 32 is slidably mounted coaxially on the protective cylinder 6, which is located above the positioning bolt 4. A locking element 7 is provided between the protective cylinder 6 and the positioning cylinder 32. During processing, the top of the protective cylinder 6 is positioned above the top of the positioning cylinder 32, and the locking element 7 is used to fix the protective cylinder 6 to the positioning cylinder 32.

[0033] Furthermore, the locking element 7 includes a first magnet 71 embedded in the side wall of the positioning cylinder 32, a groove 72 formed in the protective cylinder 6, and a second magnet 73 embedded in the bottom of the groove 72.
