★ Hardness of pressure transmitting column material: more than 55HRC
★ A positioning hole diameter at the bottom of the frame: Φ8mm
★ Gross / Net Weight: 5kg
三、校驗(yàn)方法：
★目測(cè)檢查外觀。水泥抗壓夾具應(yīng)保護(hù)清潔，不得碰傷劃痕，應(yīng)有牢固的銘牌。
★上、下壓板應(yīng)為硬質(zhì)鋼材制成，其長(zhǎng)度為40±0.1mm，寬度為40mm，厚度>10mm。
★上、下壓板與試件整個(gè)接觸表面的平面公差為0.01mm，上、下壓板自由距離>45mm。
★上壓板上的球座A應(yīng)在夾具A軸線與上壓板下表面的交點(diǎn)上，公差為±1mm，上壓板隨著與試件的接觸而自動(dòng)找平。
Third, the cement compression fixture calibration method:
★ Visually check the appearance. Cement compression fixtures shall be protected from scratches and scratches, and shall have firm nameplates.
★ The upper and lower pressure plates should be made of hard steel, with a length of 40 ± 0.1mm, a width of 40mm, and a thickness of> 10mm.
★ The plane tolerance of the entire contact surface between the upper and lower pressure plates is 0.01mm, and the free distance of the upper and lower pressure plates is more than 45mm.
四、結(jié)構(gòu)特點(diǎn)：
主要由下夾具座、上夾具座、標(biāo)準(zhǔn)夾輥、抗劈裂夾具上下壓條組成。下夾具座通過定位銷、墊圈固定在壓力機(jī)活塞上，上夾具座通過上支座、菱形銷及壓力機(jī)上的定位銷和兩內(nèi)六角螺釘固定在壓力機(jī)橫梁上。
Fourth, the structural characteristics of the cement compression fixture:
It is mainly composed of a lower clamp base, an upper clamp base, a standard nip roller, and an upper and a lower bead for anti-cracking jig. The lower clamp seat is fixed on the press piston by positioning pins and washers, and the upper clamp seat is fixed on the press beam by the upper support, diamond pins, and positioning pins on the press and two hexagon screws.
五、使用注意事項(xiàng)：
★使用前對(duì)限位尺寸檢查是否還保持正確位置；
★如果擋銷磨損超差，可以進(jìn)行打磨修復(fù)；如果擋板、插銷、定位錐頭銷磨損超差，可以重新組裝，錯(cuò)開磨損部位后繼續(xù)使用
V. Precautions for using cement compression fixture:
★ Check the limit size before use to maintain the correct position;
★ If the stop pin wears out badly, it can be polished and repaired; if the baffle, latch, and positioning cone pin are out of wear, it can be reassembled, and it can continue to be used after staggering the worn parts.
