Description

Technical Field

[0002] A chiller is a new type of environmentally friendly air-conditioning equipment that integrates multiple functions such as refrigeration, heating, ventilation and air purification. The outside of the chiller is generally provided with a shell, and the shell is generally assembled by multiple plates fixed by screws. When preparing the chiller casing, since the raw material used is a straight plate of sheet metal, at this time, in order to achieve the processing of the sheet metal into the desired shape, it is usually necessary to bend the sheet metal, and the bending operation is usually carried out on the corresponding forming equipment.

[0003] The forming equipment on the market is generally equipped with a die and a punch. When performing the bending operation, the cylinder drives the punch downward to press the sheet metal into the corresponding die to complete the bending forming operation. However, this type of forming equipment lacks a corresponding ejector assembly under the die, which is not conducive to ejecting the formed sheet metal outward, affecting the normal unloading operation. Although some forming equipment is equipped with an ejector assembly, the ejector assembly is hidden inside and there is no ventilation opening outside, which will affect the normal heat dissipation of the internal ejector assembly and bring inconvenience to the user. In view of this, we proposed a sheet metal bending equipment for chiller casings. Utility Model Content
