The invention relates to pressing auxiliary equipment, in particular to a hydraulic press fixture for fin evaporator support production. The hydraulic press fixture for fin evaporator support production comprises a base and a fixture fixing seat arranged in the middle position of the base. Sleeve fixing seats are fixed to two corners on diagonal positions of the base through inner hexagon screws; compressed springs are arranged in the sleeve fixing seats; guide pillars are arranged in the compressed springs; one end of each guide pillar is fixed into the corresponding sleeve fixing seat, and the other end of each guide pillar is connected with a sliding bearing; a wire guiding plate is connected with the sliding bearings and is in a horizontal state; and a punch is arranged in the middle position of the wire guiding plate. The hydraulic press fixture for fin evaporator support production provided by the invention is designed for producing fin evaporator supports, and is an auxiliary device used on a hydraulic press with stable performance, the wire guide plate is pressed through the hydraulic press, and the punch is driven to punch a hole on an evaporator support located on a bearing plate. The hydraulic press fixture for fin evaporator support production provided by the invention can be automatically and quickly rebounded under the action of the compressed springs after punching is completed, and is high in production efficiency and good in quality of a processed product.
