Description

Technical Field

[0001] The present invention relates to the technical field of powder metallurgy, and particularly relates to a manufacturing device for a solar tracker gear based on powder metallurgy technology. Background Art

[0002] A solar tracker is a device that can automatically adjust the orientation of a solar photovoltaic panel or a solar collector to ensure that they always face the sun, thereby improving the solar energy conversion efficiency. In a solar tracker, a gear is one of the important components for achieving precise rotation of the tracker. A worm and worm gear is a common reduction gear suitable for applications requiring a large reduction ratio. In a solar tracker, a worm and worm gear can provide a stable reduction effect to ensure smooth rotation of the tracker.

[0003] At the present stage, worms are usually processed by traditional turning instead of powder metallurgy. This is mainly because turning can achieve better machining accuracy and surface quality, but turning has problems such as high processing cost, low processing efficiency, and low material utilization rate.

[0004] However, when manufacturing a worm using powder metallurgy technology, since the two ends of the worm are smooth rods with a smaller diameter and the middle is a shaft with a larger diameter and spiral teeth, it is difficult for the pressed worm to smoothly disengage from the mold cavity, easily causing damage and deformation to the spiral teeth on the worm blank, which directly affects the machining accuracy and transmission of the worm.

[0018] 1. When the metal powder in the mold cavity is pressed into a worm blank, the piston rod of the second hydraulic cylinder contracts and pulls the sliding plate backward. The parallelogram structure composed of the sliding bar, the movable bar and a pair of hinged bars first closes upward and then moves backward, and then moves the upper mold obliquely above the lower mold to separate the upper mold from the lower mold. When the sliding plate moves backward, it will pull the clamping blocks on both sides closer to each other and clamp the upper part of the worm blank. Then, the corresponding threaded rods on both sides are driven to rotate at the same speed by the motors on both sides, and then drive the worm blank to move upward. At the same time, the lower support shaft and the lower mold are driven to rotate by the second motor, which helps the worm blank gradually separate from the mold cavity of the lower mold, and is not easy to cause damage and deformation of the spiral teeth on the worm blank, and thus will not affect the machining accuracy and transmission of the worm.

[0019] 2. When manufacturing a worm using powder metallurgy technology, material waste can be reduced, material utilization rate can be improved, and material cost and processing cost can be reduced. For complex parts such as worm gears and worms, powder metallurgy technology provides better cost-effectiveness, design flexibility and material properties. The high production efficiency and environmental protection characteristics of powder metallurgy technology also make it an ideal choice for mass-producing worm gears and worms.

[0043] In this embodiment, the demolding mechanism 30 further includes a threaded rod 310. A moving strip 301 is vertically connected to the outside of the sliding plate 203, and a moving rod 302 is vertically connected to the lower end of the moving strip 301. The front end of the moving rod 302 is connected to a moving seat 303. A pair of fixing strips 304 are symmetrically connected to the lower side of the support plate 101 on the left and right. A pair of guide rods 305 are overhangingly connected to the fixing strips 304. A T-shaped sliding seat 306 is slidably connected to the guide rods 305.

A first motor 308 is vertically downwardly installed at the outer end of the sliding seat 306, and a first pulley 309 is key-connected to its output end. The threaded rod 310 is vertically installed at the inner end of the sliding seat 306, and a second pulley 311 is key-connected to its lower end.

A pair of avoidance grooves three 101d are also symmetrically arranged on the left and right sides of the positioning port 101a, and the avoidance grooves three 101d communicate with the positioning port 101a. The threaded rod 310 and the guide frame 314 on the same side are movably arranged within the avoidance groove three 101d. When the sliding plate 203 moves backward, it will pull the clamping blocks 315 on the left and right closer to each other and clamp the upper part of the worm blank 40. Then, the corresponding threaded rods 310 are driven to rotate at the same speed by the two first motors 308, thereby driving the worm blank 40 to move upward. At the same time, the lower support shaft 318 and the lower mold 104 are driven to rotate by themselves through the second motor 321, thereby helping the worm blank 40 to gradually separate from the mold cavity of the lower mold 104.

The rubber sheet 316 can increase the friction between the clamping block 315 and the upper part of the worm blank 40, and at the same time, the clamping block 315 can be prevented from damaging the upper part of the worm blank 40.

[0046] In this embodiment, a pair of vibration motors 324 are symmetrically mounted on the upper side of the lower support plate 317. When metal powder is filled in, the vibration motors 324 can help the metal powder to fill in and fill the mold cavity.

[0047] In this embodiment, a plurality of second fixing rods 325 are evenly connected between the lower supporting plate 317 and the support plate 101. The second fixing rods 325 can realize the connection between the lower supporting plate 317 and the support plate 101, thereby improving the connection strength of the lower supporting plate 317.

[0052] S4: When the sliding plate 203 moves backward, it will pull the clamping blocks 315 on the left and right sides closer to each other and clamp the upper part of the worm blank 40, and then drive the corresponding threaded rods 310 to rotate at the same speed through the motor 1 308 on both sides, thereby driving the worm blank 40 to move upward. At the same time, the motor 2 321 drives the lower support shaft 318 and the lower mold 104 to rotate, thereby helping the worm blank 40 to gradually separate from the mold cavity of the lower mold 104.
