Abstract

This utility model discloses a stamping unit for a stamping machine tool, including a base, a stamping seat on the top of the base, a buffer groove on the top of the base, a buffer column and a buffer spring inside the buffer groove, four sets of grooves on the top of the base, gears and two sets of toothed plates inside the grooves, and four sets of telescopic columns on the top of the base, each telescopic column having a spring inside. The bottom of the right-side telescopic column is fixedly connected to the toothed plate. In this stamping unit of the stamping machine tool, during stamping, the stamping plate moves downwards, utilizing the buffer columns in the buffer groove to buffer the pressure. Furthermore, with the cooperation of the toothed plates on the outer ring of the buffer columns and the gears, the toothed plates in the grooves, together with the telescopic columns, move upwards to top the buffer seat, further buffering the pressure with the springs. This achieves the purpose of multiple buffering of the stamping process by the machine tool, solving the problem that existing stamping machines cannot effectively buffer the pressure during the stamping process.

Description

Technical Field

[0001] This utility model relates to the field of stamping machine tool technology, specifically to a stamping unit of a stamping machine tool. Background Technology

[0002] A punch press is essentially a stamping press. In national production, stamping technology is increasingly widely used due to its advantages over traditional machining: saving materials and energy, high efficiency, lower operator skill requirements, and the ability to produce products that cannot be achieved through machining using various molds. Stamping production primarily deals with sheet metal. Using molds, it can produce blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extruded parts, etc., and is widely used in various fields.

[0003] Currently, most stamping units of stamping machines have the problem of difficulty in effectively buffering the pressure during the stamping process. For example, in the prior art: CN 216397667 U, a CNC machine tool mold stamping mechanism includes: a base, crankshafts rotatably connected to the opposite sides of the two side rods, an upper pressure plate fixedly connected between the two first sliding sleeves, a lower pressure plate fixedly connected between the two second sliding sleeves, and two symmetrically arranged elastic components between the upper and lower pressure plates, and a servo motor on the upper surface of the actuation mounting plate.

[0004] Other existing technologies:

[0005] CN 212043415 U, A cap pressing mechanism on a stamping machine tool;

[0006] CN 212598174 U, A stamping machine tool with buffer function.

[0007] Although the aforementioned existing technical solutions all achieve the purpose of buffering and stabilizing stamping in stamping machines through various design methods, they all have similar problems: When using this CNC machine tool mold stamping mechanism, a servo motor and crank transmission mechanism are used to drive the pressure rod together with the upper pressure plate and the upper mold to cooperate with the lower mold for stamping operations. However, during the cooperation of the upper and lower molds, the elastic component between the upper and lower pressure plates is used to achieve buffering stamping. However, since the lower mold is in a fixed state and there is no upward buffering force, the large force during stamping can easily cause the single return spring in the elastic component to be over-compressed and damaged.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The stamping unit of this stamping machine tool, through the coordinated use of buffer groove, buffer spring, toothed plate, gear, telescopic column, spring and stamping seat, allows the stamping plate to move downward during stamping, using the buffer column in the buffer groove to buffer the pressure.

[0028] In this embodiment, during stamping, the stamping plate 2 moves downward to buffer the pressure using the buffer column 4 in the buffer groove 3. With the cooperation of the toothed plate 8 and gear 7 on the outer ring of the buffer column 4, the toothed plate 8 in the groove 6, together with the telescopic column 9, moves upward to the top column buffer seat 2, which, in conjunction with the spring 10, provides secondary buffering, thus achieving the purpose of multiple buffering stamping by the machine tool.

[0029] The installation adjustment mechanism 11 includes an installation plate 111, which is located at the bottom of the base 1. An adjustment groove 116 is provided on the top of the installation plate 111, and an adjustment block 112 is provided in the inner cavity of the adjustment groove 116.
