  從叉車結構規劃上避免腐蝕

  Avoid corrosion from forklift structure planning
  (1)在叉車整體安置上考慮避免腐蝕介質積累。盡量避免關閉區域,或堅持關閉系統通風和排水杰出,如考慮內燃叉車整機的通風、散熱。發動機發作的尾氣盡量從配重的下部排放或經過凈化、降溫從配重上部向上排放。關于蓄電池叉車如前移式叉車,可開設通風窗,以堅持電動機散熱和通風,蓄電池箱底開設漏液孔和裝置積液器。
  (1) avoid the accumulation of corrosive media in the overall placement of forklift trucks. Avoid closing the area as far as possible, or insist on closing the outstanding ventilation and drainage system, such as considering the ventilation and heat dissipation of the whole diesel forklift. As far as possible, the exhaust gas from the engine is discharged from the lower part of the counterweight or from the upper part of the counterweight after purification and cooling. For battery forklift trucks such as forward forklift trucks, ventilation windows can be opened to adhere to motor cooling and ventilation, and leakage holes and liquid accumulators can be installed at the bottom of battery boxes.
  (2)在外形規劃上留意防護、避免積存水汽和塵土。國外先進叉車非常重視造型規劃,如Linde、HYSTER、TOYOTA、JUNGHEINRICH等品牌叉車,造型流通,既表現美感和功用規劃,又不易積水和積垢,非常值得學習。
  (2) pay attention to protection and avoid accumulation of water vapor and dust in shape planning. Foreign advanced forklift trucks attach great importance to modeling planning, such as Linde, HYSTER, TOYOTA, JUNGHEINRICH and other brand forklift trucks. Modeling circulation, which not only expresses aesthetic and functional planning, but also is not easy to accumulate water and scale, is worth learning.

  (3)留意顯露件的維護。電器材與接頭安置在內側,或加防護罩殼。整車顯露易腐蝕和易進水的部位設防塵罩。例如,歪斜液壓缸、轉向液壓缸活塞桿顯露段設防塵套;車身上多處顯露工藝孔或功用孔設防水塞。
  (3) pay attention to the maintenance of exposed parts. Electrical equipment and joints are placed inside or with protective cover. The vehicle can expose the dust cover which is easy to corrode and easy to enter. For example, the exposed section of the piston rod of the inclined hydraulic cylinder and the steering hydraulic cylinder is provided with a dust-proof sleeve, and the waterproof plug is installed in the exposed process holes or functional holes of the car body.
  (4)零部件規劃時考慮其均勻腐蝕,挑選一種或幾種組合防腐辦法。叉車常用的防護辦法有涂層、電鍍、轉化膜和涂防銹油、脂等。不同的工藝,具有不同的耐腐蝕功能。例如杭州H系列叉車,曾經許多銷、軸、螺栓、支架外表為發黑處理,液壓缸缸蓋等諸多顯露加工面不進行處理,使得叉車還未出廠就已銹蝕。經過完善外表處理要求,進步零件規劃的合理性,以及有用規范外表處理工藝,促進了產品外觀質量和耐蝕性的進步。
  (4) selecting one or several combination anticorrosion methods when considering the homogeneous corrosion of parts and components. The usual protection methods for forklifts include coating, electroplating, conversion coating and antirust oil and grease. Different processes have different corrosion resistance functions. For example, Hangzhou H series forklift truck, many pins, axles, bolts, brackets were blackened, hydraulic cylinder head and other exposed processing surfaces were not processed, making the forklift truck rusted before leaving the factory. Through improving the requirements of surface treatment, improving the rationality of part planning and standardizing the surface treatment process, the improvement of product appearance quality and corrosion resistance was promoted.
  選用涂層防腐,需清晰油漆涂層的特性和質量目標。例如,車身結構件涂層著重裝飾性和耐蝕性;前后橋等的涂層著重維護性;蓄電池箱的涂層著重耐酸性;排氣管等的涂層著重耐熱性等。選用金屬鍍層,須依照GB/T13911—1992《金屬鍍覆和化學處理表明辦法》進行表明。螺紋緊固件參照GB5267—1985《螺紋緊固件電鍍層》規范斷定鍍層要求。一般選用7~10μm的鍍鋅層,就能取得較好的防護作用。對在重蝕環境下的零件,選用20~25μm的鍍鋅層。留意金屬鍍層的后處理及后處理的色彩,避免構成色彩稠濁,影響整機外觀。
  Selection of coating anticorrosion requires clear paint coating characteristics and quality objectives. For example, the coatings of body structure parts focus on decoration and corrosion resistance; the coatings of front and rear axles focus on maintenance; the coatings of battery boxes focus on acid resistance; and the coatings of exhaust pipes focus on heat resistance. Selection of metal coatings shall be indicated in accordance with GB/T 1391-1992 "Indicative Measures for Metal Coating and Chemical Treatment". Threaded fasteners refer to GB5267 - 1985 "thread fasteners plating layer" specification to determine coating requirements. Generally, the zinc coating of 7~10 M can be used for better protection. For the parts with heavy corrosion, 20~25 - M zinc plating is used. Pay attention to the color of metal coating after treatment and post-treatment, avoid the formation of thick color, affect the appearance of the machine.
  (5)留意避免縫隙腐蝕、電化學腐蝕、應力腐蝕開裂。對不可避免的縫隙結構如發動機罩拼焊縫隙用密封膠關閉。異金屬銜接應盡量選取電位接近的金屬,或采納絕緣辦法避免電化學腐蝕。
  (5) attention should be paid to avoiding crevice corrosion, electrochemical corrosion and stress corrosion cracking. The inevitable gap structure, such as the tailor welded joint of the engine hood, is closed with sealant. The proximity of metal should be selected as the potential for joining of different metals, or the insulation method should be adopted to avoid electrochemical corrosion.
  (6)零件的結構要便于防護工藝的施行,必要時開設工藝孔。例如,油箱上開孔的方位要有利于噴槍嘴掩蓋悉數外表進行噴丸處理。對化學前處理的工件如護頂架要開設工藝孔,避免積液。
  (6) the structure of the parts should be easy to carry out the protective technology, and the technological holes should be opened if necessary. For example, the position of the opening on the fuel tank should be good for the spray nozzle to cover all the exterior surfaces for shot peening. For chemical pre-treatment workpieces such as roof guards, process holes should be set up to avoid effusion.
  (7)考慮選用功能的耐腐蝕資料,如鍍鋅板、彩卷板、復合資料和工程塑料等。玻璃鋼具有工藝性好、比強度高、成本低的特色,合作隔熱墊能夠達到必定的隔熱和下降噪聲的作用,已運用于叉車發動機罩、蓄電池箱蓋和一般護罩等。現在運用的玻璃鋼零件遍及是以不飽和聚脂樹脂和無堿玻璃纖維為首要原資料,合作鋼板加強筋疊壓制造而成,可取得杰出的外觀質量,無焊接構成的焊棱和油漆難以掩飾的點焊疤痕,但耐久性差,易老化,合適試制和小批量產品。對批量大的罩殼類定型零件,選用工程塑料(如ABS工程塑料)替代玻璃鋼,可取得更好的裝飾性和耐久性。發動機罩受環境影響較大,選用薄鋼板或鍍鋅板合作涂層防護更為合理。叉車將更多地學習轎車業新資料的運用。
  (7) Consider selecting corrosion-resistant materials with excellent functions, such as galvanized sheet, color roll sheet, composite materials and engineering plastics. FRP has the characteristics of good workmanship, high specific strength and low cost. Cooperative heat insulation pad can achieve certain heat insulation and noise reduction. It has been used in forklift engine hood, battery cover and general shield. Now the fiberglass reinforced plastics parts are made of unsaturated polyester resin and alkali-free fiberglass as the primary raw materials, and the reinforcing ribs of the cooperative steel plate are laminated and pressed. The excellent appearance quality can be obtained. The spot welding scars which are hard to conceal by the welding edges and paints without welding are poor in durability, easy to aging, suitable for trial production and small batches. Products. For large batches of shell shaped parts, the use of engineering plastics (such as ABS engineering plastics) instead of FRP can achieve better decorative and durability. It is more reasonable to choose thin steel plate or galvanized sheet to protect the hood. The forklift will learn more about the new information in the car industry.
