The invention relates to a hydraulic valve cover manufacturing process. The process includes the following steps of a, discharging, wherein the required raw material is prepared according to weight and size, b, heating, wherein heating is conducted on the raw material in a heating furnace, c, upsetting, wherein the heated raw material is placed in an upsetting die, unsetting is conducted on the raw material to form a workblank, and the oxide skin on the surface of the workblank is removed; d, dummying, wherein performing is conducted on the workblank generated after the oxide skin is removed to form a pre-forging piece, e, precision forging, wherein fine machining is conducted on the preformed workblank to form a precision forging piece, f, burr cutting, wherein burrs of the precision forging piece are cut on a punching machine, g, normalizing, wherein the precision forging piece generated after burr cutting is conducted is placed in a furnace, and normalizing is conducted on the precision forging piece, h, shot blasting, wherein the oxide skin on the surface of the precision forging piece generated after normalizing is conducted is removed and i, cold sizing, wherein local cold sizing is conducted on the precision forging piece on a cold forging machine. According to the hydraulic valve cover manufacturing process, the workblank is formed through hot forging, then cold-extrusion is conducted on a key face, the plane degree and parallel degree are guaranteed, traditional machinery machining is replaced, the production cost is saved, and the forged piece is high in mechanical strength and stable in size accuracy.

The invention provides a punching machine which comprises a shell, a drive assembly, an eccentric shaft, an oil cylinder, a hydraulic pump, a push shaft, an upper punch die, a lower punch die and an oil return assembly. The drive assembly is arranged in the shell. The eccentric shaft is connected with the drive assembly. The oil cylinder is arranged in the shell. The hydraulic pump comprises multiple piston assemblies arranged in the circumferential direction of the eccentric shaft. Each piston assembly is provided with multiple oil holes communicating with the oil cylinder. The eccentric shaft rotates to drive the multiple piston assemblies to move in the direction perpendicular to the axis of the eccentric shaft, and oil in the oil cylinder is extruded into an oil cavity of the hydraulic pump. The push shaft is arranged in the shell and connected with the oil cavity of the hydraulic pump. After the oil enters the oil cavity, the push shaft moves in the direction where the lower punch die is located. The upper punch die is connected with the push shaft. The lower punch die and the upper punch die are oppositely arranged on the shell. The oil return assembly is connected with the push shaft, the oil cavity and the oil cylinder. After the push shaft moves to the limited position in the direction where the lower punch die is located, the oil return assembly is started, and the oil in the oil cavity flows back into the oil cylinder through the oil return assembly.

The invention relates to a speed reducer for a concrete mixing main machine. The speed reducer comprises an upper casing, a lower casing, a planet carrier assembly, an inner gear and a gear shaft, wherein teeth are arranged at one end of the gear shaft in the peripheral direction, the gear shaft extends into the planet carrier assembly and meshed with all planet gears in the planet carrier assembly, the planet gears of the planet carrier assembly are meshed with the inner gear, the planet carrier assembly is arranged between the upper casing and the lower casing, and the planet carrier assembly is of a single-end floating type supporting structure to achieve transmission. Due to the facts that the planet carrier assembly is of the single-end floating type supporting structure to achieve transmission and the two ends are not supported by a bearing, the coaxiality requirements for bearing holes needn't to be taken into consideration. Thus, the processing efficiency is improved. Meanwhile, the single-end floating type supporting structure can balance load between all planet gears in the planet carrier assembly, the gear side gap between the planet gears and the inner gear can be adjusted by self according to radial stress on the planet gears, the rotation noise is reduced, and the stability and the reliability of transmission are improved.
