Description

Technical Field

[0001] The utility model relates to the technical field of die extrusion, in particular to a die extruder for tooth-shaped parts. Background Art

[0002] In the past, gear shaft parts were processed by cutting, which was a complex production process with high cost, low efficiency and difficult quality assurance. After adopting the cold extrusion forming process, the manufacturing process of the parts is simple, the productivity is increased by more than 20 times, and less waste is achieved, raw materials are saved, and the quality of the parts is significantly improved.

[0003] However, in the prior art, when processing internal gear sleeve parts, it is often necessary to manually take the processed finished products out of the device, which is time-consuming, labor-intensive and has a high risk factor. In addition, when the position of the device needs to be adjusted, it is necessary to use external force or manual labor to lift the device to adjust the position, which is time-consuming, labor-intensive and has a low movement efficiency.

[0011] 1. The utility model extrude the raw material into shape by setting a pressing block. When the pressing block is displaced to the lowest point, the top end of the top block is just flush with the upper surface of the partition plate. At this time, the tension spring is stretched by force, and the raw material is squeezed into shape by the pressing block. When the hydraulic rod is reset, the sliding plate drives the top block to move upward under the elastic force of the tension spring. At this time, the top block can push the shaped raw material out of the molding cavity during the upward movement, thereby facilitating the process of the staff taking the shaped raw material out of the molding cavity, solving the problem of the inconvenience of taking finished products of the traditional mold extruder for tooth-shaped parts.

[0012] 2. The utility model is provided with a walking wheel. When the whole device needs to be moved, the hand wheel is used to drive the worm to rotate. The worm rotates and meshes with the worm wheel. At this time, the worm wheel drives the screw to rotate together. During the rotation of the screw, the screw can drive the support foot to move upward and retract into the support column through the screw sleeve. At this time, the walking wheel contacts the ground, so the whole device can be moved. The hand wheel is rotated in the opposite direction to make the support foot contact the ground again to fix the device. At the same time, the height of the support table can be adjusted by rotating the hand wheel, which solves the problem of inconvenient movement of traditional mold extruders for tooth-shaped parts.
