Problems solved by technology

However, for the structure of the double toggle, its disadvantage is that it cannot meet the requirements of high-speed stamping. In order to realize the high-speed stamping of small plates, some punching machines adopt the structure of single toggle.
[0004] However, the structure of the single toggle has poor balance in the up and down direction, resulting in that the stability and precision in the stamping process cannot meet the requirements

Embodiment Construction

[0025] It is particularly pointed out that the terms "first", "second", and "third" in the present invention are only used for descriptive purposes, and cannot be interpreted as indicating or implying relative importance or implicitly indicating the indicated technical features. quantity. Thus, features defined as "first", "second", and "third" may explicitly or implicitly include at least one of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. All directional indications (such as up, down, left, right, front, back, etc.) When a specific posture changes, the directional indication changes accordingly.

[0026] Below by embodiment technical solution of the present invention is described further:

[0027] The invention provides a single toggle press, combined with figure 1 and figure 2 As shown, the punch press includes: a support mechanism 1, a casing 2, a stamping...

Abstract

The invention discloses a dynamic balance single-toggle-joint punching machine. The dynamic balance single-toggle-joint punching machine comprises a punching mechanism (3), a toggle joint (4), a driving mechanism (5) and a balance adjusting mechanism (8), and the driving mechanism (5) and the balance adjusting mechanism (8) are connected with the toggle joint (4). Through adjustment of the balanceadjusting mechanism, the toggle joint can achieve dynamic balance in the moving process, the four speed changing processes of accelerated descending, decelerated descending, accelerated ascending anddecelerated ascending are completed in one punching period, the situation that due to toggle joint unbalance, the displacement of a punching mechanism is too large or too small, and the punching precision is influenced is avoided, and therefore, the high-speed and high-precision punching requirements are met at the same time.

Description

technical field [0001] The invention relates to a punch press, in particular to a dynamic balanced single toggle punch press. Background technique [0002] A punch press refers to a device used to carry out a stamping production process. Stamping production is mainly for sheet metal. Through molds, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts can be made, which are widely used in various fields. [0003] At present, most of the punch presses adopt the structure of double toggles. During the stamping process, the left and right toggles can maintain a relative balance to form a stable and high-precision stamping operation. However, for the structure of the double toggle, its disadvantage is that it cannot meet the requirements of high-speed stamping. In order to realize high-speed stamping of small plates, some punching machines adopt a single toggle structure. [0004] However, the structure of the single toggle h...
