Abstract: A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.

Abstract: An automobile hub fixture includes a fixture body and a positioning apparatus. The fixture body includes a fixed platform and a plurality of clamping claws arranged at intervals in a circumferential direction of the fixed platform. The clamping claws are configured to clamp an outer rim of a hub. The plurality of clamping claws are connected to a driving member by using a linkage, and the driving member drives the clamping claws to radially move along the fixed platform. The positioning apparatus includes a movable platform slidably connected to the clamping claws. A positioning module configured to position an inner rim or the outer rim of the hub is mounted to the movable platform. The machining device includes a fixture, a machine tool, and a minimal quantity lubrication apparatus. The production line includes a machining device, a loading system, a loading and unloading manipulator, and a catching table.

Abstract: The present invention relates to a powder dry-pressing molding device and method.

Abstract: A multi-connected air conditioner unit and method of operating the same, wherein, when an air-side heat exchanger is put into operation, and a water-side heat exchanger is not put into operation, a four-way valve is used to control a refrigerant to pass through said air-side heat exchanger, in realizing the refrigerating or heating operation of said unit; when said air-side heat exchanger is not put into operation, and said water-side heat exchanger is put into operation, said four-way valve is used to control said refrigerant to pass through said water-side heat exchanger to heat water, in achieving full recovery of heat; when both said compressors are put into operations concurrently, a dispenser is used to transport refrigerant oil separated by a second oil separator to an oil inlet pipe, then it is input to said compressor via an air suction pipe; and when a portion of compressor is put into operation, and another portion of compressor is not put into operation, since said air suction pipe is installed up

Abstract: A screw type wind-chilling water chiller unit including a chassis and a compressor, a shell and tube heat exchanger, a fin-type heat exchanger and an expansion valve, and a control cubicle disposed on the chassis. The expansion valve is disposed between the compressor and the shell and tube heat exchanger. The shell and tube heat exchanger is provided with three tubes, a first tube connected to the compressor, a second tube is connected to a liquid storage can via the expansion valve and a transmission tube. A heat exchange tube in the fin-type heat exchanger is connected to a collection tube, and the liquid storage can is connected to the third tube, and a handle of a cubicle door of a control cubicle is connected to a power switch inside a power supply box, so as to improve the performance, operation stability, equipment safety of the unit.
