Follow-up clamping in trimming

The trimming of large-size rectangular workpieces is mass-produced. At present, the overall frame clamp is usually used for clamping. The clamp structure is huge, and the power source is gas, liquid and power. The follow-up clamping mechanism adopted by our factory is mechanical clamping, which has the characteristics of simple structure, low cost and good reliability compared with the former. The clamping device is used in a special machine for trimming (Fig. 1). The workpiece material is ABS plastic plate, the thickness of the trimming edge is 3~5mm, the trimming dimension is rectangular 1800Ã—800mm, and the four sides are simultaneously milled.

Refrigerant is the fluids which complete the thermodynamic cycle of a chiller.It absorbs the heat of the cooled object at low temperatures and then transfers it to the cooling water or air at a higher temperature. In a vapor compression type refrigerator, a refrigerant capable of liquefying at normal temperature or lower temperature is used as a refrigerant such as freon (fluorine, chlorine, bromine derivatives of saturated Hydrocarbons), azeotropic mixture A mixture of Freon in a certain proportion of azeotropic solution), hydrocarbons (propane, ethylene, etc.), ammonia etc.
