It is described according to the hydraulic tool of this utility model embodiment referring to Fig. 1 to Figure 10。It should be understood that for illustrative purposes, herein for crimping tool that pipe is operated so that principle of the present utility model to be described。But, this utility model is not limited to crimping tool, for instance, this utility model can also be applied to clamp tool, cutting implement, compression tool etc.。
Referring to Fig. 1, it illustrates the crimping tool for pipe is crimped according to this utility model embodiment。As it is shown in figure 1, can be the form of hand held electric tool according to the crimping tool 1 of this utility model embodiment。Crimping tool 1 can include crimping unit (or being called working cell) 30, driver element 20 and the connection unit 26 between crimping unit 30 and driver element 20。Crimping unit 30 can be configured to the workpiece of such as pipe is crimped。Driver element 20 can be configured to driving pressure order unit 30。
Referring to Fig. 2, it is the elevational schematic of the hydraulic tool according to this utility model embodiment。As in figure 2 it is shown, crimping unit 30 includes two crimping components 31 and 33。The two crimping component 31 and 33 can be the form of plate, in one plane side by side and be disposed adjacently。Preferably, crimping component 31 and 33 can have same structure, and the axis that pass is therebetween is substantially symmetric, and wherein, described axis is approximately perpendicular to the longitudinal axis treating crimping workpiece (such as, pipe) and is properly termed as the axis of symmetry。At this, describe in order to convenient, the side adjacent one another are (face) of crimping component 31 and 33 is called inner side (face), and its side (face) away from each other is called outside (face)；The end (portion) of the contiguous driver element of crimping component 31 and 33 is called the inner (portion), and the end (portion) that will be far from driver element is called outer end (portion)。
Crimping component 31 and 33 each includes pressure contact portion and for driving the drive division of pressure contact portion。The pressure contact portion of crimping component 31 and 33 near outer end and includes electrolysis 311 and 331 on medial surface, and workpiece is placed in the space formed by the electrolysis 311 and 331 of crimping component 31 and 33。The drive division of crimping component 31 and 33 near driver element and includes cam surface (or being called driven surface) 312 and 332 on medial surface。
Pin connected mode can be passed through be arranged between two side plates 35 by crimping component 31 and 33。As it can be seen, crimping component 33 is connected between two side plates 35 by pin 34, by pin 32, crimping component 31 is connected between two side plates 35。So, when cam surface 312 and 332 drived unit drives, crimping component 31 pivots around pin 32, and crimps component 33 and pivot around pin 34。That is, when cam surface 312 and 332 pivots away from each other, electrolysis 311 and 331 pivot toward each other, and vice versa。
In the example shown in the series of figures, side plate 35 is in substantially T-shaped, including transverse part and leg。Being separately provided for receiving the hole of pin 32 and 34 at the two ends place of transverse part, and be arranged around the hole for receiving pin 36 at the free end of leg, wherein, pin 36 for being connected to connection unit 26 and and then being connected to driver element 20 by crimping unit 30。
