The specific embodiment
Have generally by prior art known pressure machine frame 2 structures at the forcing press shown in Fig. 11, it mainly comprises cylinder beam 3 and to back timber 4, and the bracket institution of being made up of four single pressure pillars 65 (here illustrating to an example).In each pressure pillar 6 inside the pull bar 7 that is formed from steel is set respectively.Each pull bar 7 not only protrudes in cylinder beam 3 outside but also protrudes in back timber 4, the locking nut 10 or 11 (here illustrating to example) of can on each end 8 and 9 of pull bar 7, screwing respectively thus.Said pressure pillar 6 makes cylinder beam 3 and bearing crosshead 4 spaces, and pressure machine frame 2 utilizes pull bar 7 to apply pretension on the whole.This point realizes thus, and two locking nuts 10 and 11 through each pull bar 7 of screwing make parts cylinder beam 3, bearing crosshead 4 and pressure pillar 6 mutual extrusion thus and make pressure machine frame 2 be in pretension simultaneously.These pressure machine frame 2 bearing pressure devices 12, it mainly comprises that by anvil block 13 and pressure punch 14 driver element 15 forms, and this driver element has cylinder, and it is arranged on the cylinder beam 3.And anvil block 13 is positioned on the bearing crosshead 4.When pressure apparatus 12 work, produce high pressure 16, they must be born by pressure machine frame 2.Be provided with pull bar 7, they react on pressure 16 for this reason.Therefore pull bar 7 bears pulling load and necessary corresponding firmly design size, and extruding force 16 can not make pressure machine frame 2 plastic deformations thus.Can imagine easily that said pull bar 7 must design very solidly in the big forcing press of several tons of extruding forces, make them construct very weightily and correspondingly operate bothersomely thus, especially when assembling level press 1.The pretension that forms pull bar 7 in addition is bothersome relatively, because locking nut 10 and 11 often can only be with heavy equipment assembling.In very large forcing press, the difficulty more of the level press 1 shown in here for example, pull bar 7 is because its long length is loaded down with trivial details in operation.This is a several reasons, and the pressure machine frame 2 that therefore has common pull bar is disadvantageous.
Through avoid the major defect of conventional apparatus at the pre-tightening apparatus shown in Fig. 2 20.
Said pre-tightening apparatus 20 has lashing post 21, and it mainly is made up of first column cap 22, second column cap 23 and unique strain component 24.
25 extend and bear acting pulling force column cap 22 and 23 from first column cap, 22 to second column caps 23 along tension distance at this unique strain component 24.
Two column caps have the device 26 of the direction counter-rotating (first column cap 22 is shown to an example) that is used to make unique strain component 24 here in this embodiment.Between two column caps 22 and 23, only a plurality of tensions sections 27 are worked thus, make the fracture strength of this lashing post 21 be several times as much as the fracture strength of unique strain component 24 thus through unique strain component 24.
Therefore unique strain component 24 has the tension distance segment zone 28 more than along tension distance 25, and the pulling force that acts on unique strain component 24 is distributed on a plurality of tension sections 27 of unique strain component 24 along tension distance 25.
Therefore unique more than 24 ground of strain component is from first column cap, 22 to second column caps 23 and return the setting of guiding ground.In order to make unique strain component 24 along more than 25 guiding of tension distance, strain component had the length that is several times as much as tension distance 25.Unique in this embodiment strain component 24 is processed by the tension rope 29 of steel wire rope form.
Certainly, in alternative lashing post, also can use the tension rope 29 shown in other strain component conduct here.
Therefore unique strain component 24 can constitute in this embodiment with reeling, for example during transporting this pre-tightening apparatus 20, can fold easily thus.This coiling or folding advantageously several times ground reduce the volume that transports of lashing post 21.
Therefore this lashing post 21 can adopt working depth and another height at least, assembling height and/or transport height for example, wherein said another highly can be less than working depth 1/3rd or be less than half of working depth.
Whole lashing post 21 can be adjusted with changing, because unique strain component 24 can turn on column cap 22 or 23 according to the different number of times of user demand ground on its height.
