Abstract

A press apparatus is arranged such that a movable table (31) is disposed such as to be vertically movable in opposition to a pressure-receiving frame (1) with pillars (3) as guides. A single or plurality of independent liquid-filled uniform-pressure chambers (32, 55) are provided in at least one of the pressure-receiving frame (1) and the movable table (31). According to this arrangement, working surfaces (9, 10) for mounting dies (23, 24) are allowed to become floating plates, whereby any deflection generated in the pressure-receiving frame (1) or the movable table (31) is corrected.

In other words, the movable table 31 is mainly divided into a work table 33 and a movable table body 34, and a work surface 1 (に δ in the size of J) is interposed between the two. An EE chamber 32 is provided for filling the liquid, and the working table 33 is floated due to the presence of the equalizing chamber 32.

In a space independent of the outside world, the height h was about a few! Oil is sealed at zero pressure. When the hydraulic pressure device 30 is used as a “heating press”, the molds 23 and 24 are heated up, so that the heat sealing oil is not used. Oil will be used.
こ の均圧室 3 2 は シ リ ン ダ フ レ ー ム 2 に形成されてい る EE力室 1 5 ， 1 6 とは独立且つ密閉されている も ので ある。 従って前述のよ う に 「加熱ブレ ス」 と して用いる 場合でも圧力室 1 5 は均圧室 3 2 と別個でしかも ヒ - ト アッ プされる下金型 2 4 よ り 雜れているため ， 圧力室 1 5へ袷排される油に特別の冷却は不要である。 尙均圧室 3 2 の高さ はプ レ ス の能力， 又は作業テ - ブ ル 3 3 の 厚さに じ適宜决定され， その中に適当な圧力に よ 与 圧した油を.封入して も良いこ とは勿論である。  The pressure equalizing chamber 32 is independent and sealed from the EE force chambers 15 and 16 formed in the cylinder frame 2. Therefore, even when the pressure chamber 15 is used as a “heating brace” as described above, the pressure chamber 15 is separate from the pressure equalization chamber 32 and is surrounded by the lower mold 24 that is heated up. , No special cooling is required for the oil drained into the pressure chamber 15. (5) The height of the pressure equalizing chamber 32 is determined as appropriate according to the capacity of the press or the thickness of the working table 33, and the oil pressurized by an appropriate pressure is filled therein. Of course, it is also good.

The two are integrated.中 In the figure, reference numeral 39 denotes a parting line, which indicates the boundary between the working table 33 and the movable table body 34. The boundary is indicated by the root 37 and the counter panel 38. Therefore, the two are surely connected. Also, a bolt hole 40 is provided in the vicinity of the mounting portion 12 of the movable table main body 34 in which the ring 41 is inserted, and the movable tape main body 34 is worked together. The bolt 42 is mounted over the table 33 and the movable table body 34 when the upper and lower dies 23 and 24 are mounted is moved.

It is fixed at a position where the mold can be accurately matched with 3). In addition, the working table 3 3 is provided with an oil filling port 4 6 for allowing oil to enter the uniform E chamber 3 2. ing.尙 The shape of the work table 33 is free, but there are many squares that match the lower mold 24.

In the process, the internal E force applied to the lower mold 24 from the pressurizing means via the movable table 31 caused the lower mold 24 to contact the upper mold 23. The reaction force acts on the lower mold 24 as a reaction force at the floor, and the reaction force automatically acts vertically on the work table 33 via the oil inside the E chamber 32. Therefore, the working tape 33 is supported by the completely evenly distributed hydraulic pressure inside the pressure equalizing chamber 32. (4) The amount of liquid compressed in the equalizing chamber 32 can be almost neglected because the height の of the equalizing chamber 32 itself is small. Then, assuming that the working template 33 is a part of the lower mold 24 as a floating plate, the lower mold 24 is considered to be in equilibrium conditions. + Working table 3 3 [Floating blade] is to constitute one elastic body, and this one elastic body depends on hydraulic pressure.

When the movable table body 34 is going to move further, the counterbore panel 38 is combined with the holder 37. The working table 33 can be moved independently of the movable table body 3 by the swing line 39, and the floating plate is deformed due to addition. It deforms so as to apply a uniform load to the mold while following the mold.

Thus, the lower mold 24 and the work table S3 (f α-ting plate) are one element that constitutes one elastic body. The fact that one elastic body is directly and completely subjected to the uniform distribution load by the liquid E in each of the four equal chambers 61, 61 1 .6 1c. It means that a state can be obtained.

The range of this movement is restricted to the range of the dimension α between the upper and lower surfaces 65, 67. In addition, a uniform load is applied to the lower mold 24 while trying to knead it. In the unlikely event that the filled liquid in the pressure equalizing chambers 61a, 61c, 61c, 61l leaks, the lower part 67 is supported by the upper part 65 and this supporting state , Excluding the convex portion 68 of the working table 63 and the concave portion 66 of the movable table body 64. The work table 63 can be prevented from being excessively deformed because it can be obtained from the upper and lower surfaces 65 and S7, which are the mating surfaces of the movable table 3 and the movable table body 64.

It is easy to add because it should be possible, i.e., conversely, if the maximum machining length of the target machine tool is assumed to be twice as large as 2 ^ It is possible to easily process the uniform E-chambers 6 1, 6 1 .6 1c, 6 1d up to the table 6 3.
