Punching method of air conditioner rear cover plate

Abstract

The invention discloses a punching method of an air conditioner rear cover plate. The air conditioner rear cover plate is punched through a punching die, and the punching die comprises an upper die and a lower die; and the upper die comprises a plurality of punching heads arranged in a rectangular uniform array mode, the lower die comprises a lower die plate, a movable frame arranged on the periphery of the lower die plate and a driving device used for driving the movable frame to move, and a clamp is arranged on the movable frame. The punching machining method comprises the following specificsteps that 1), the air conditioner rear cover plate is fixed through the clamp, the upper die and the lower die are closed, and first-time punching machining is completed; 2), the movable frame is driven to move leftwards in the X-axis direction, the upper die and the lower die are closed, and second-time punching machining is completed; 3), the movable frame is driven to move backwards in the Y-axis direction, the upper die and the lower die are closed, and third-time punching machining is completed; and 4), the movable frame is driven to move rightwards in the X-axis direction, the upper die and the lower die are closed, and fourth-time punching machining is completed. According to the punching method of the air conditioner rear cover plate, the machining efficiency of the air conditioner rear cover plate is effectively improved.

Description

technical field [0001] The invention relates to a punching method for an air conditioner rear cover. Background technique [0002] At present, when processing the rear cover of the air conditioner, dense heat dissipation holes need to be punched out on the rear cover of the air conditioner. Due to the dense heat dissipation holes, it is difficult to complete the punching process of the rear cover of the air conditioner with only one set of molds. Therefore, the traditional processing method Four sets of punching dies are needed, and the punching process is carried out in four times, but this method is inefficient, increases the development and maintenance costs of the mold, and is likely to cause scratches on the product surface during product transfer, which will affect product quality . Contents of the invention [0003] The object of the present invention is to provide a punching method for the rear cover of the air conditioner, which effectively improves the processin...
