如何判斷木屑顆粒機模具的質量

木屑顆粒機模具的好壞不隻是模具不耐磨這一個壞處,模具容易爆模,更換頻率提高,勞動強度增加,因此選擇合格的木屑顆粒機模具,是節約成本提高生產效率,最有效地途徑。
Sawdust particles machine mould quality not only mould don't wear this one disadvantage, mould easily burst mode, change the frequency increase, increase the intensity of labor, so choose qualified sawdust particles machine mold, is to increase the production efficiency, cost saving is the most effective way.
木屑顆粒機環模通常由碳鋼或不鏽鋼資料經鍛壓、切削、鑽孔、熱處理等工序製成。
Sawdust particles machine ring die are usually made of carbon steel or stainless steel material by forging, cutting, drilling, such as heat treatment process is made.
一、環模所用的材料和每個加工工序對其運用壽命及製粒質量、產值有直接的影響。
A, materials used in the ring die and each processing procedure for its using life and granulating quality, output has a direct impact.
因而,選購環模時,必定要選用技能過硬,有必定規劃的廠家。若是隨意選用技能設備落後的小廠,在出產過程中肯定會呈現這樣或那樣的疑問(比方環模不出料、商品顆粒表麵粗糙、爆模等)。其次,模孔的研磨也是非常重要的,小廠家由於設備技能約束,主要靠人工進行拋光,經常呈現漏拋表象,或許達不到所需求的光潔度。因而這樣的環模,在實際生產過程中也是將難以,即使出料,也會構成顆粒表麵粗糙和塞機表象。所以用戶們應在秸稈顆粒機的環模質量方麵把好關。
Therefore, when the choose and buy ring die, must choose superior skills, some have planning manufacturers. If small plant of optional choose skills, poor equipment, will appear in the process of producing this or that questions (for example loop die not discharging, commodity grain surface is rough, detonation mode, etc.). Secondly, die grinding is also very important, the small manufacturer skills constraints due to equipment, mainly by manual polishing, often appear behind appearances, leakage may not meet the requirements of finish. Therefore the ring die, will not be in the actual production process, even if the material, will constitute a rough surface particles and machine surface. So users should be in the straw quality of ring die pellet machine, the better off.
二、合理選擇模具的厚度
Second, the reasonable choose the thickness of the mould
正確選用適宜的模具厚度是確保商品質量和產值的一個重要環節,它涉及到一個壓縮比問題(壓縮比=模孔有用長度/模孔直徑)。壓縮比大的環模,其構成的顆粒密度大,表麵光潔。否則,所產顆粒外觀鬆懈,造成秸稈顆粒含粉率高。但壓縮比若是過大,會令環模難於出料,以致模孔堵塞。 針對出產含纖維比高的物料,環模壓縮比應相對取小些,或用舊模出產。
Right to choose the suitable thickness of mould is to ensure the quality and output of an important link, it involves a question of compression ratio (compression ratio = die useful length/die hole diameter). Compression ratio of ring die, its form grain density is big, the surface is bright and clean. Otherwise, particle appearance from the lax, straw particle high powder content. If the compression ratio is too big, can make ring die hard to discharge, so that the die hole plug. To produce fiber material than high, ring die compression ratio should be relatively small, or use the old mould produce.
三、調好木屑顆粒機壓輥和環模間的相互合作
Third, adjusted the sawdust pellet machine mutual cooperation between the roller and ring die
如果壓輥和環模的空隙調整是不是合理,直接影響木屑顆粒機的作業狀況。間距過大,則由於環模和壓輥之間的擠壓力不足以戰勝物料經過模孔的摩擦力而造成堵塞。過小則易損傷環模及壓輥。所以若要把握好合理的間距,需要靠顆粒工經過長時間的出產實踐和仔細探究才能做出正確的調整。這裏有些環模與壓輥的適應經驗和大家分享下,即是新模配新輥,一對壓輥固定一個環模合作運用。這樣,就可避免新模配舊壓輥,或許舊模配新壓輥等表象,以免造成新壓輥或是新模具的磨損。從而間接進步和延伸環模、壓輥的運用壽命,減少生產成本。
If press roller and the ring die gap adjustment is reasonable, directly affect the sawdust pellet machine operation condition. Spacing is too large, because the ring die and roller pressure between the extrusion pressure is not enough to overcome the friction material through the die and cause clogging. The small ring die and roller is easy to damage. So if you want to grasp the reasonable spacing, need to rely on grain work after a long time production practice and explore to make the correct adjustment. Here are some ring die and roller to adapt to experience and share, namely the new roller is matched by a new mould, a pair of roller fixed using a ring die cooperation. In this way, can avoid the mold with old roller, perhaps the old mould with the new roller surface, so as not to cause new roller or new mould wear and tear. Indirect progress and extension ring mold, the use of the roller life and reduce the cost of production.
四、做好木屑顆粒機環模的保護工作
Four, to do a good job of the protection of the sawdust particles machine ring die
一個環模運用作用好與壞,除自身技術質量決議外,肯定離不開環模的保護。由於在出產過程中,一個環模必定會有阻塞、磨損現象,這樣的環模,若是不進行必要的保護保護,必然構成產值下降,能耗增大,乃至壓不出料,呈現堵機表象。因而,有上述表象發作時,有必要對環模進行一係列的保護作業。
A ring die use effect is good or bad, in addition to their own technological quality resolution, certainly cannot leave the ring die protection. Because in the process of produce, to have a ring die block, wear phenomenon, so the ring die, if you are not necessary protection protection, necessarily constitute output drop, increase of energy consumption, and not discharging, rendering machine. Therefore, there is the surface occurs, it is necessary to ring die the protection of a series of operations.
五、木屑顆粒機模具的修複使用
Five, sawdust pellet machine mold repair use
木屑顆粒機的成型需要模具和壓輪皮做出犧牲,由於木屑顆粒成型難,必須有強大的力量才能夠使顆粒成型,如此必然造成模具的磨損。根據以往經驗,AG8並不支持廠家進行模具的修複。因為修複模具,無非是增大孔的錐度。但是,在修複中也會造成淬火的硬度受損,以至於修複後很短時間內就會磨損到出粉率高、不成形、密度小、溫度低這個狀態。修複所產生的費用能否抵負生產的成本也是AG8需要慎重考慮的問題。所以廠家在出現模具損壞的情況,最好是添置新的模具,以免在後續的生產中問題的出現。
Sawdust particles forming die and roller skin to make sacrifices, because sawdust particles molding difficult, must have a powerful force to make particles forming, so inevitably cause mould wear and tear. Based on past experience, we do not support manufacturer for mold repair. Because the repair mold, is nothing but increase the taper hole. But also can cause the quenching hardness in repair damaged, that within a very short time after repair will wear into the flour extraction rate is high, not forming, small density, low temperature of the state. Costs of repair will justify the cost of producing negative is the problem we need to carefully consider. So manufacturers, in the case of a mold damage, it is best to add the new mold, in order to avoid problems in the subsequent production.
