Shutter die

Abstract

The invention discloses a shutter die which comprises a male die and a female die. The female die is provided with a forming die, the male die is provided with at least one cutter which is used for punching plates, the cutter is provided with a blade, and height difference exists between the first end and the second end of the blade. According to the shutter die, from the aspect of microscopic view, point-by-point cutting of the plates is achieved in short time, and the punching force, the noise and the vibration are lowered.

Description

technical field [0001] The invention relates to the field of molds, in particular to a shutter mold. Background technique [0002] At present, the processing and forming of the shutters on the market requires two processes. For example, the shutters on the housing of the window machine air conditioner are processed by punching first, and then flanging to complete the production of the shutters. The punching method is line punching. like Figure 1 to Figure 3 As shown in the figure, using this method in production has large punching force, high noise and large vibration, which is the production difficulty of sheet metal stamping. For example, a 40-piece shutter requires a punching force of about 150 tons, and the noise is in the More than 110 decibels; and a window cover part has a maximum of 14 units of shutters, so the total punching force is as high as 2,100 tons. Therefore, a lot of equipment is involved and the number of punching times is also large. At the same time, la...

Problems solved by technology

[0002] At present, the processing and molding of shutters on the market requires two processes. For example, to process the shutters on the shell of the window machine and air conditioner, punch the opening first, and then turn the side to complete the production of the shutters. The punching method is line punching, and the tools used like Figure 1 to Figure 3 As shown, the punching force, noise, and vibration of this method are large during production, which is a difficult point in the production of sheet metal stamping. For example, a shutter with 40 pieces as a unit requires a punching force of about 150 tons. The noise is More than 110 decibels; and a window machine cover part, there are at most 14 units of shutters, so the total punching force is as high as 2100 tons, so there are a lot of equipment involved and a lot of punching times. At the same time, large punching force and punching eccentric load , It is easy to cause the loss of precision of the sliders of many punching machines, which can no longer be used in the production of shutters. Such predatory use of punching machines has a huge impact on punching machines, resulting in high processing costs and low processing efficiency
