And, for ease of understanding and describing the present invention, as shown in Figure 2, the lifting direction that represents top pad with four-headed arrow, and from drawing, rising into direction is also the direction of motion or upstroke direction upwards, and landing direction is also the downward direction of motion or downward movement direction.Meanwhile, described four-headed arrow also represents the lifting linear movement direction of described boundary bit unit.
The specific embodiment
See figures.1.and.2, according to main embodiment of the present invention, for the stroke adjusting device 300 of the top pad 320 of forcing press, comprise block parts 234, stroke axostylus axostyle 17 and stroke limit parts 49; Described stroke limit parts 49 and described block parts 234 are arranged on described stroke axostylus axostyle 17; Described stroke limit parts 49 comprise boundary's bit unit 10; Described apical cap 1 carries out elevating movement under the effect of the push rod 210 of the lifting power plant 200 of top pad, and simultaneously described apical cap 1 drives described stroke axostylus axostyle 17 to move in the travel range of described boundary bit unit 10 and 234 restrictions of described block parts; At described top pad 320, under rest position, the distance between described boundary bit unit and described block parts 234 is determined the range of described apical cap 1 and described stroke axostylus axostyle 17.
With reference to the disclosed view of patent documentation CN201752938U and Fig. 1 of the present invention, can find out, the range of described top pad is to be determined by the range of described stroke axostylus axostyle.And the range of described stroke axostylus axostyle is to determine like this: at described top pad, under rest position, the distance between described boundary bit unit and described block parts is determined the range of described stroke axostylus axostyle 17.
In Fig. 1 of patent documentation CN201752938U, can find out, described external thread sleeve plays the effect of boundary's bit unit, and described block parts are arranged on the lower end of described stroke axostylus axostyle 3.The range of described stroke axostylus axostyle 3 is determined by the distance between described external thread sleeve and described block parts.And the size of described distance can be by regulating the relative position between described external thread sleeve and described block parts to realize.In patent documentation CN201752938U, motor 1 drives worm gear reducer device to rotate, the described transmission rotatablely moving by inner screw sheath and external thread sleeve is converted into described external thread sleeve along the rectilinear motion of described stroke axostylus axostyle 3, therefore, the relative position between described external thread sleeve and described block parts is changed.
And, with reference to the disclosed Fig. 1 of patent documentation CN201752938U and Fig. 1 of the present invention, can clearly be seen that the main distinction of the disclosed technical scheme of patent documentation CN201752938U and design of the present invention: in patent documentation CN201752938U, the lower end of piston rod 5 connects adjusting screw(rod) 3, that is to say, the center line of described stroke axostylus axostyle or adjusting screw(rod) 3 overlaps with the center line of described push rod or piston rod 5, and therefore described stroke axostylus axostyle and described push rod are in series arranged; Described stroke limit parts 9 are fixedly attached on cylinder rack, be positioned at described cylinder under.
