Description

本願発明は鍛造品製造分野に関し、具体的にはアルミニウム合金鍛造品の冷間鍛造装置である。 The present invention relates to the field of forging product manufacturing, and specifically is a cold forging device for an aluminum alloy forged product.

鍛造とは、金属加工の塑性加工法の一種であり、金属をハンマー等で叩いて圧力を加える事で、金属内部の空隙をつぶし、結晶を微細化し、結晶の方向を整えて強度を高めると共に目的の形状に成形する。鍛造加工は鍛造の温度によって熱間鍛造、温間鍛造、冷間鍛造と分類されている。有り触れた鍛造の一つは、アルミニウム合金の鍛造であり、アルミニウム合金の材料が柔らかいため、冷間鍛造の手段をよく使用する。既存のアルミニウム合金の鍛造は、アルミニウム合金表面に酸化膜が存在するため、段階的な軟化作業が不可欠であるが、軟化操作が複雑で高度な自動化を実現できなく、また、鍛造はほとんどライン作業により実現され、異なる金型に対する鍛造加工は段階的に行われる必要があり、操作が難しい。 Forging is a type of plastic working method for metal processing. By hitting the metal with a hammer or the like to apply pressure, the voids inside the metal are crushed, the crystals are made finer, the direction of the crystals is adjusted, and the strength is increased. Mold into the desired shape. Forging is classified into hot forging, warm forging, and cold forging according to the forging temperature. One of the forgings that we have come across is the forging of aluminum alloys, and because the material of the aluminum alloy is soft, cold forging means are often used. In the forging of existing aluminum alloys, stepwise softening work is indispensable because an oxide film exists on the surface of the aluminum alloy, but the softening operation is complicated and high degree of automation cannot be realized, and forging is almost line work. It is difficult to operate because the forging process for different dies needs to be performed step by step.

初期状態に、移動ばね４０が圧縮された状態にある。 In the initial state, the moving spring 40 is in a compressed state.

まず、アルミニウム合金の表面の酸化膜を軟化させ、手動で旋転ロッド６２を回し、引っ掛かりブロック５８を回転させることにより、引っ掛かりブロック５８が固定ブロック５９に止められなくなり、手動で支持ロッド６１を回し、蓋板６０を回転させ、載置ブロック２０の中にアルミニウム合金の原料を入れ、手動で引っ掛かりブロック５９を固定ブロック５９に止められるように復帰させ、動力モーター１８を起動し、動力軸１７が動力モーター１８に駆動されて回転し、動力ロッド１９が動力軸１７とともに回転することにより、載置ブロック２０が駆動されて貯蔵空間１３の中まで回転して試薬に浸され、しばらくして再び動力モーター１８を起動し、動力軸１７を回転させ、動力ロッド１９が動力軸１７とともに回転することにより、載置ブロック２０が駆動されて回転し、復帰し、旋転モーター１４を起動し、旋転軸１５を回転させ、載置ブロック２０が旋転軸１５とともに次の貯蔵ブロック１２の上方まで回転し、アルミニウム合金の原料をそれぞれ異なる貯蔵空間１３の中浸すことにより、異なる時間でアルミニウム合金の軟化作業が実現される。 First, by softening the oxide film on the surface of the aluminum alloy, manually turning the rotating rod 62, and rotating the hooking block 58, the hooking block 58 cannot be stopped by the fixed block 59, and the support rod 61 is manually turned. The lid plate 60 is rotated, the raw material of the aluminum alloy is put in the mounting block 20, the block 59 is manually returned so that it can be stopped by the fixed block 59, the power motor 18 is started, and the power shaft 17 is powered. Driven by the motor 18 to rotate, the power rod 19 rotates together with the power shaft 17, so that the mounting block 20 is driven to rotate into the storage space 13 and immersed in the reagent, and after a while, the power motor is again used. 18 is started, the power shaft 17 is rotated, and the power rod 19 is rotated together with the power shaft 17, so that the mounting block 20 is driven to rotate and return, the rotation motor 14 is started, and the rotation shaft 15 is rotated.

鍛造完了後、液圧ポンプ３０が液圧ロッド５１を上方に復帰させ、液圧ロッド５１が復帰する方向では、第二捻りばね５３の弾性力が圧力ばね５５の弾性力より大きいため、推力ロッド４９が昇降ロッド５４を上昇させ、圧力ブロック５６が昇降ロッド５４とともに上昇し、圧力ブロック５６がラック４２を上昇させ、ラック４２と伝動歯車４８との噛合により、伝動歯車４８が回転し、動力傘歯車４６が伝動歯車４８とともに回転し、動力傘歯車４６と伝動傘歯車４４との噛合により、伝動傘歯車４４が回転し、伝動傘歯車４４が連結軸２５を回転させ、連結軸２５がねじブロック２４を回転させ、次の鍛造加工に便利を与えるために貯蔵缶２７の中の潤滑液を作業台４１の上端面に噴き付ける。 After the forging is completed, the hydraulic pump 30 returns the hydraulic rod 51 upward, and in the direction in which the hydraulic rod 51 returns, the elastic force of the second torsion spring 53 is larger than the elastic force of the pressure spring 55, so that the thrust rod 49 raises the elevating rod 54, the pressure block 56 rises together with the elevating rod 54, the pressure block 56 raises the rack 42, and the meshing of the rack 42 and the transmission gear 48 causes the transmission gear 48 to rotate and the power umbrella. The gear 46 rotates together with the transmission gear 48, and the meshing of the power cap gear 46 and the transmission cap gear 44 causes the transmission cap gear 44 to rotate, the transmission cap gear 44 rotates the connecting shaft 25, and the connecting shaft 25 is a screw block.
