DETAILED DESCRIPTION

A limit frame 131 is fixedly installed on the lower surface of the cooling chamber 130, and three unloading push rods 134 are fixed on the unloading push rod support plate 132. The unloading push rod support plate 132 contacts and cooperates with the limit frame 131. The limit frame 131 is used to limit the downward movement range of the unloading push rod support plate 132 to prevent the unloading push rod 134 from separating from the cooling chamber 130. The unloading push rod support plate 132 is fixed on the top of the third guide slide bar 125. The second guide slide bar 124 and the fourth guide slide bar 126 are also fixedly installed on the lower surface of the cooling chamber 130, wherein the second guide slide bar 124 and the third guide slide bar 125 are slidably sleeved with a first beam plate 123, and the first beam plate 123 is fixedly equipped with a feeding drive rack 122, and the third guide slide bar 125 and the fourth guide slide bar 126 are slidably sleeved with a second beam plate 136, and the second beam plate 136 is fixedly equipped with a punch drive rack 119. A frame beam 104 and a side support beam 112 are fixedly mounted on the base 101, and the tops of the frame beam 104 and the side support beam 112 are fixedly matched, wherein a gearbox bracket 105 and a first guide slide bar 106 are fixedly mounted on the frame beam 104, wherein a traction and feeding rack 109 is slidably mounted on the first guide slide bar 106, and the traction and feeding rack 109 is fixedly matched with the feeding frame 107, a gearbox 108 is fixedly mounted on the gearbox bracket 105, a feeding driven gear 121 that contacts and meshes with the feeding drive rack 122 is fixedly mounted on the input shaft of the gearbox 108, and a feeding drive gear 120 that meshes with the traction and feeding rack 109 is fixedly mounted on the output shaft of the gearbox 108.A punch traction rack 113 is slidably mounted on the side support beam 112, and a punch driving gear 118 is also rotatably mounted on the side support beam 112, wherein a speed increasing gear 127 is coaxially fixed to the side of the punch driving gear 118, the speed increasing gear 127 is meshed with the punch driving rack 119 for transmission, the punch driving gear 118 is meshed with the punch traction rack 113 for transmission, and a punch mounting frame 114 is fixed to the top of the punch traction rack 113, wherein the punch 115 is fixed to the punch mounting frame 114 by a locking screw 116. A tension spring 128 and a spring 129 are respectively arranged around the fourth guide slide bar 126 and the third guide slide bar 125, wherein the two ends of the tension spring 128 are respectively fixed to the cooling chamber 130 and the second beam plate 136, wherein the two ends of the spring 129 are respectively in contact with the first beam plate 123 and the unloading push rod support plate 132. A driving motor 137 is fixedly mounted on the base 101 , and a driving screw 117 is fixedly mounted on the output shaft of the driving motor 137 . The driving screw 117 is threadedly matched with the first beam plate 123 , and the top end of the driving screw 117 is rotationally matched with the frame beam 104 .

[0022] The working principle of a flexible processing gear casting equipment disclosed in the present invention is as follows: pour metal powder raw materials into the loading frame 107, start the drive motor 137, the drive motor 137 drives the drive screw 117 to rotate, and the drive screw 117 controls the first beam plate 123 to move up and down. At this time, the first beam plate 123 is controlled to move upward, and the loading drive rack 122 will follow the movement, and synchronously the spring 129 will also drive the unloading push rod 134 on the unloading push rod support plate 132 to move upward. When the feeding drive rack 122 contacts the feeding driven gear 121, the unloading push rod support plate 132 moves to the topmost position, that is, the position in contact with the cooling chamber 130. At this time, the unloading push rod support plate 132 cannot move. When the feeding drive rack 122 continues to move upward, the spring 129 begins to compress, and at the same time, the feeding drive rack 122 drives the feeding driven gear 121 to rotate. The feeding driven gear 121 drives the feeding drive gear 120 to rotate through the gearbox 108. The rotation of the feeding drive gear 120 drives the traction feeding rack 1 09 slides linearly on the first guide slide bar 106, and drives the loading frame 107 to slide linearly on the platform plate 103, and moves the loading frame 107 to the die 133. At this time, the metal powder inside the loading frame 107 will fall into the die 133 and fill the die 133. Then the first beam plate 123 is controlled to move downward, so that the loading frame 107 and the unloading push rod 134 are reset. In this process, the bottom edge of the loading frame 107 will scrape the metal powder inside the die 133, so that the metal powder inside the die 133 is flush with the upper surface of the die 133.

[0023] When the first beam plate 123 moves to the position in contact with the second beam plate 136, it will press down the second beam plate 136, thereby driving the second beam plate 136 to move downward (the second beam plate 136 is arranged below the first beam plate 123 and contacts and cooperates with the first beam plate 123). The downward movement of the second beam plate 136 will drive the punch driving rack 119 to move downward, and the punch driving rack 119 will drive the speed increasing gear 127 to rotate. The speed increasing gear 127 rotates synchronously with the punch driving gear 118. The rotation of the punch driving gear 118 will drive the punch traction rack 113 to move downward. At this time, the punch mounting frame 114 on the punch traction rack 113 and the punch 115 on the punch mounting frame 114 will move downward. Prior to this, the induction heating coil 135 inside the cooling chamber 130 is started to heat and melt the metal powder, and then the punch 115 is inserted into the die 133 to flatten the upper surface of the molten metal powder, and circulating cooling water is introduced into the cooling chamber 130 (the induction heating coil 135 is turned off) to allow the molten metal powder to cool and shape. At this time, the first beam plate 123 is controlled to move upward. This process will cause the second beam plate 136 to move upward under the action of the tension spring 128, thereby driving the punch 115 to move upward, so that the punch 115 is separated from the die 133. When the feeding drive rack 122 moves to contact the feeding driven gear 121 here, the unloading push rod 134 has pushed the cooled and formed gear upward, that is, the lower surface of the cooled and formed gear is flush with the upper surface of the die 133. In the subsequent movement of the feeding frame 107, the gear will be pushed away, and then the metal powder will continue to be poured into the die 133.

[0024] According to the size parameters of the formed gear, the female mold 133 and the male mold 115 are replaced, and the female mold 133 and the male mold 115 need to be replaced synchronously. The two are in a mutually coordinated relationship, and a draft angle is also provided in the female mold 133. In order to improve the continuity of gear forming, new raw materials need to be continuously poured into the upper material frame 107.
