“…The mechanism belongs to the fourth class according to the classification of I.I. Artobolevsky [7], since the driven kinematic chain contains a four-sided closed loop and the structural group (2,3,4,5,6,7) does not break up into groups of a smaller order.…”

“…Therefore, from the beginning it is necessary to select the assembly of the mechanism, and as a consequence, to set the initial values of the variable parameters on which the continuous movement of the mechanism is possible. The problem of determining the assembly and the initial position of the mechanism, is solved by replacing the leading link [3], i.e. by choosing another variable as a generalized coordinate, which makes it possible to simplify the solution of the original system (2).…”

“…The study and expansion of the functional capabilities of crank-slide actuating mechanisms based on four-link structural groups is attractive for the development of new designs of crank presses and other stamping and forging machines [1,2]. They eliminate such disadvantages of existing crank presses as the distortion of the working slider in the process of forging compression and the limitations of the design for the implementation of the working slider dwells [1,3,4].…”

“…The rigidity of the press significantly affects the duration of the loading and unloading phases: the greater the rigidity of the links, the shorter the contact time, the rigidity of the press significantly affects the duration of the loading and unloading phases: the greater the rigidity of the links, the shorter the contact time of the stamp with the forging. This is especially important for increasing the stability of stamps in hot stamping processes [3,5]. However, an increase in the rigidity of the press structure leads to an increase in its metal consumption, which is not always economically feasible.…”

In crank presses, an important role is played by the presence of actuators with dwell, in which, with continuous movement of the input links, the output working link remains stationary at some part of the work. The use of a high-class structural group (fourth class) expands the functionality of the crank press, including it can ensure the link dwell of the working link on a given section of movement during the required period of time. As a result of the conducted research, four variants of actuators of the crank knee press were designed. Due to the rational choice of the positions of racks and crosshead guide, the best layout of the dimensions of the press mechanism has been achieved, changing the coordinates of the racks accordingly allows to design a mechanism with upper or lower dwells of the working links. When synthesizing (selecting) parameters such as: l_2 and h, it is possible to obtain a height of different duration. All this is shown on the basis of a numerical experiment based on kinematic analysis. In addition, the complex structure of the mechanism makes it possible to ensure the exact link dwell, which cannot be achieved due to the well-known knee presses based on the second-class mechanism [21].

Changing the coordinates of the racks accordingly allows for designing a mechanism with upper or lower dwells of the working links. The duration of the dwell of the working link (slider) can be adjusted by selecting the distance between the racks with rotational pairs and a crosshead guide of the mechanism. All this is shown on the basis of a numerical experiment based on kinematic analysis. In addition, the proposed structure of the mechanism makes it possible to ensure the exact link dwell, which cannot be achieved due to the well-known knee presses based on the second-class mechanism.
