This utility model provides an automatic return device based on a cam mechanism, comprising: a base plate fixed to a pump body at the end of a displacement control shaft; a cam mechanism fixed to the displacement control shaft and circumferentially connected thereto, the outer circumferential surface of the cam mechanism having a V-groove; a slider mechanism, one end of which is rotatably connected to the base plate, and the other end extending into the V-groove and rollingly connected thereto, wherein when the displacement control shaft is in the return-to-center state, the slider mechanism is located at the bottom center of the V-groove; and a reset mechanism connected between the slider mechanism and the pump body, applying a preset pulling force to the slider mechanism to maintain contact between the slider mechanism and the V-groove.

This application provides a method and apparatus for waste heat recovery from high-temperature solid materials. The apparatus includes a support frame with a rotary heat exchange box mounted on it. One end of the rotary heat exchange box is connected to a power unit, which is fixed to one side of the support frame. A rotating shaft is rotatably mounted on the other side of the support frame and connected to the other end of the rotary heat exchange box. A material fixing device is fixed inside the rotary heat exchange box. In this application, the power unit drives the rotary heat exchange box to rotate at a low speed, which in turn drives the material fixing device to rotate at a low speed. This causes continuous and omnidirectional relative motion and contact renewal between the heat exchange medium and the solid material, thereby achieving dynamic, uniform, and efficient direct contact heat transfer. This fundamentally solves the problems of low heat exchange efficiency and uneven cooling caused by poor contact in static filling.

The application discloses a double-cylinder hydraulic shaping equipment, and belongs to the technical field of hydraulic shaping, which comprises a base, a gas-liquid supercharging cylinder, a material supporting frame, a guide rail assembly, a driving assembly, a feeding assembly and a loosening assembly, the base is fixedly installed on the ground, a lower die plate is installed on the top of the base, the gas-liquid supercharging cylinder is arranged above the base, an output end of the gas-liquid supercharging cylinder is provided with a top plate, the bottom of the top plate is provided with an upper die plate, the material supporting frame is fixedly installed on the ground, the guide rail assembly is installed on the top of the base, the driving assembly is arranged between the base and the top plate, the feeding assembly is installed on the driving assembly, and the loosening assembly is installed on the side wall of the lower die plate. The application solves the problems of low feeding efficiency, high labor intensity and hidden safety hazards caused by the fact that the feeding of the traditional hydraulic shaping equipment usually relies on manual operation. The driving assembly, the feeding assembly, the guide rail assembly and the loosening assembly are arranged, the automatic conveying of materials is realized, and the production efficiency is improved.
