This invention provides a pre-forging equipment and method for gear forging production, relating to the field of gear forging technology. It includes a waste collection module, a powder preparation module, and an extrusion bar module, as well as a circulation control module electrically connected to each of these modules. The waste collection module is used to classify and collect waste generated before and after gear forging, and then transport the waste to the powder preparation module. The powder preparation module is used to sequentially crush, grind, remove impurities, clean, dry, and classify the received forging waste to prepare a metal mixed powder, which is then transported to the extrusion bar module. The extrusion bar module is used to press the metal mixed powder filled in the die cavity into pre-forged billets of a preset specification, achieving high-value recycling of gear forging waste, replacing the traditional remelting method, significantly reducing energy consumption and metal loss, improving material utilization, and significantly reducing production costs.

This application discloses an ultrasonic shot peening control method for a U-shaped inner cavity of a high-temperature alloy low-vortex disk, relating to the field of ultrasonic shot peening. The method includes: dividing the inner cavity into three process areas based on its geometry: a straight groove section at the inlet, a rounded corner section at the bottom, and a rotary exit section; precisely positioning the workpiece on a high-precision rotary table of a multi-axis CNC machine tool using a dedicated fixture, and establishing a reliable workpiece coordinate system. Based on this, a differentiated CNC path is generated using the workpiece CAD model to drive the relative motion of the ultrasonic vibrating head, ensuring that different areas enter the effective impact range with trajectories matching their curvature characteristics. During shot peening, acoustic and vibration signals are acquired in real time and energy spectrum analysis is performed to dynamically determine coverage adequacy and energy distribution. The dwell time and dwell position are adaptively adjusted based on the analysis results and updated collaboratively with the CNC path, thereby achieving precise, uniform, and continuous strengthening of the complex inner cavity.

This invention provides a cooling structure for a film-making machine, including a steel belt and a liquid storage tank located below the steel belt. A spray assembly is installed inside the liquid storage tank, and a filter assembly is installed below the spray assembly. The side of the filter assembly is fixedly connected to the inner wall of the liquid storage tank, and an anti-clogging assembly is installed above the filter assembly. The anti-clogging assembly and the spray assembly are respectively fixedly connected to the actuator of a synchronous drive component. Cleaning brushes and scraper blades are installed on the left and right sides of the spray assembly, with their tops contacting the bottom surface of the steel belt. This invention uses the spray assembly to spray cooling liquid onto the bottom surface of the steel belt, cooling the steel belt and facilitating subsequent film-making processes. The filter assembly filters the returned liquid before it is used by the spray assembly, allowing the coolant to be recycled and conserving water resources.

This invention provides a coffee brewing system and a coffee machine, belonging to the field of coffee machine technology. The coffee brewing system includes a machine body and a brewing head assembly, a brewing chamber assembly, and a coffee pusher assembly mounted on the machine body. The free ends of the brewing head assembly and the coffee pusher assembly can approach each other and compress the coffee powder falling into the brewing chamber to form a coffee cake. The coffee brewing system also includes a first filter and a second filter. One of the first and second filter is located at the free end of the brewing head assembly, and the other is located at the free end of the coffee pusher assembly. The first and second filter are opposite each other. The second filter has a filter cavity formed by a recess in the direction away from the first filter, and the inner diameter of the filter cavity gradually decreases in the direction away from the first filter. One of the free ends of the brewing head assembly and the coffee pusher assembly is the liquid outlet, and the other is the liquid inlet. The coffee cake extruded by this brewing chamber is a cone-shaped convex cake with a thicker center and relatively thinner edges, improving the quality of the coffee.
