Gidravlik pressning asosiy parametrlari
Asosiy parametrlar gidravlik pressning asosiy texnik ma'lumotlari bo'lib, ular gidravlik pressning texnologik ishlatilishi va strukturasi turiga qarab belgilanadi. Bu gidravlik pressning ish qobiliyati va xususiyatlarini aks ettiradi, shuningdek, asosan, gidravlik pressning kontur o'lchamini va umumiy yalpi og'irligini aniqlaydi. Asosiy parametrlar foydalanuvchi tomonidan tanlanadi. Sotib olish uchun asosiy asos. Xo'sh, gidravlik pressning asosiy parametrlari qanday? Shlangi pressning parametrlarini qanday tushunish va tanlash mumkin? Bugun men siz uchun umumiy uch{0}}nurli to'rtta-gidravlik pressning asosiy parametrlarini saralayman.
1. Nominal kuch (KN)
The nominal force is generally the main parameter of the hydraulic press, which reflects the working capacity of the hydraulic press. The nominal force is the maximum working pressure that the hydraulic press can nominally issue, and is numerically equal to the product of the maximum liquid pressure and the total area of the working plunger (piston radius) R²πpressure gauge value (system pressure)
Note: 1MPa≈100N
Take 60T calculation as an example: cylinder diameter φ180mm system pressure 25MPa (for high pressure)
90903.1425÷10000 (unit conversion)
2. Maksimal bosh balandligi (ochilish balandligi)
The maximum clearance distance refers to the distance from the upper surface of the table to the lower surface of the movable beam when the movable beam stops at the upper limit position. The maximum clearance distance reflects the size of the working space of the hydraulic press in the height direction. It should be determined by process factors such as the height of the mold and the corresponding backing plate, the size of the working stroke, and the size of the space required for placing the blank and taking out the workpiece. The maximum clearance has a great influence on the overall height of the hydraulic press, the length of the column, the stability of the hydraulic press body and the height of the installation workshop. The maximum clearance distance of the single-arm hydraulic press is the distance from the lower plane of the indenter to the upper surface of the table.
3. Maksimal zarba
The maximum stroke refers to the distance from the lower plane of the column guide sleeve of the movable beam to the upper plane of the column travel limit sleeve when the movable beam is at the upper limit position, that is, the maximum distance that the movable beam can move. The maximum stroke should be determined according to the required maximum working stroke during the workpiece forming process.
4. Jadval o'lchami (uzunlik kengligi)
The workbench is generally the place where the mold is placed. The size of the worktable refers to the effective size that can be used on the worktable, and the size of the worktable depends on the plane size of the mold and the arrangement of the process.
5. Tomoq chuqurligi (bir-ustunli gidravlik press)
Refers to the distance from the center of the single-column hydraulic press head to the inner surface of the frame.
6. Qaytish kuchi
The return force refers to the weight of the movable part, the force required for the return process (such as the draft force, the lifting force of the chopping knife), etc.
7. Harakatlanuvchi nurning harakat tezligi (slayder tezligi): uni ishchi zarba tezligiga, bo'sh strok (suyuqlik to'ldirish zarbasi) tezligi va qaytish tezligiga bo'lish mumkin.
The idle travel and return travel can generally be higher to improve productivity, but too fast will cause shock and vibration when stopping or reversing.
Tezlikning uch turi mavjud:
⑴Constant speed (eternal speed): rising speed, falling speed (using electro-hydraulic reversing valve)
⑵Differential: ①Fast down, slow back ②Slow down, fast back, idle descending, pressing, and returning (with cartridge valve) ③Up and down equal velocity
(3) Tez (suyuqlik bilan to'ldirish tizimi): Shuningdek, u o'z vazniga tayanib tushish o'rniga, atayin tezlikni oshiruvchi silindr bilan- jihozlangan;
8. Nominal chiqarish kuchi va ejeksiyon zarbasi
The function of the ejector cylinder is to eject or stretch, and the power and stroke safety of the ejector are determined by the process requirements;
9. Shlangi cho'zuvchi Y27 bitta ta'sirli varaq-, shuningdek, gidravlik prokladka kuchi va gidravlik prokladka zarbasi parametrlarini bilishi kerak.
10. Y28 qo'sh{2}}harakatli varaq chizma gidravlik pressi shuningdek, tortish kuchi parametrlarini, bo'sh ushlagich kuchini, chizma slayderining zarbasini, blank ushlagichning zarbasini, bo'sh joyning ochilish balandligini bilishi kerak. chizilgan slayder va bo'sh ushlagichning ochilish balandligi.
11. Yagona ustunli gidravlik pressning-patron turi yoki ustki slayderli (bosuvchi plastinka turi) tuzilishi, ish stolini tuzatish zarurmi va hokazo.
12. Harakatlar ketma-ketligi (harakat jarayoni) Buyurtmachi presslash jarayoni ketma-ketligini va jarayon talablarini (jarayon talablarini) ta'minlaydi.
