Abstract
The utility model discloses a linkage structure for the press machine link rod plunger piston, comprising a link rod, a plunger, a brasses, and a joint pin connecting the link rod with the plunger. The utility model is characterized in that the brasses is provided in the semicircle orifice of the plunger piston; the joint pin is a concentric structure with the brasses; the semicircle at the location where the joint pin is connected with the link rod is made into an eccentric filled-short structure, and the eccentric diameter is less than that of the joint pin. With the structure, the pin is free from force, solving a problem that the pin is easy to be damaged, allowing easy lubrication and obviously reduced external fault.
Description
Technical field
The utility model relates to a kind of syndeton, relates in particular to a kind of connecting rod and plunger connecting structure for pressure machine.
Background technology
At present, connecting rod is connected two fulcrum link pins and the three fulcrum link pin structures of adopting more with plunger on straight side press, this kind structure is owing to mainly bear stamping press by connecting pin, it is bigger that the connecting pin diameter need be made, lubricated also not too convenient, press plunger need be made very big, just can avoid pin distortion and damage.
Summary of the invention
The purpose of this utility model just provides a kind of connecting rod and plunger connecting structure for pressure machine, to avoid the problem of connecting pin stress deformation when the punching press.
The purpose of this utility model is to realize like this, a kind of connecting rod and plunger connecting structure for pressure machine, the connecting pin that comprises connecting rod, plunger, brasses, connecting rod and plunger are linked together, it is characterized in that: brasses is installed in the semicircle orifice of plunger, connecting pin and brasses are concentric structure, connecting pin is connected with connecting rod and is prepared into the eccentric material structure that lacks on the semicircle at position, and its eccentric diameter is less than the connecting pin diameter.
Good effect of the present utility model is: avoided connecing pin pin stress deformation when punching press, solved pin and damaged problem easily, thereby can reduce the diameter of pin, the corresponding apparatus piece volumes is diminished, save material, easily lubricated, the lathe overall structure is more reasonable.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure 1, connecting rod, 2, connecting pin, 3, brasses, 4, plunger.
The specific embodiment
As shown in Figure 1 and Figure 2, connecting rod and plunger connecting structure for pressure machine described in the utility model comprises connecting rod, plunger, connecting pin and brasses that connecting rod and plunger are linked together.Brasses 3 is installed in the semicircle orifice of plunger 4, and connecting pin 2 is a concentric structure with brasses 3, and connecting pin 2 is prepared into the eccentric material structure that lacks on the semicircle at the position that is connected with connecting rod 1, and its eccentric diameter is less than connecting pin 2 diameters.Connecting pin 2 is stressed when guaranteeing that connecting rod 1 rises, and connecting pin 2 does not stress during stamping-out downwards, and brasses 3 is stressed.
Preparation method: at first that the connection pin-and-hole on the plunger 4 is concentric with the processing of brasses 3 semicircle orifices, press brasses 3, process brasses 3 surfaces again, it is concentric to guarantee that one side brasses 3 and plunger 4 are connected pin-and-hole, guarantees brasses 3 tolerances on the other hand; Then connecting rod 1, connecting pin 2 are fixed on the plunger 4, guarantee connecting pin 2 eccentric part on plunger 4 positive tops, this structure fabrication assembling is finished.
