[0010] Figure 1 This is a schematic diagram of the structure of this utility model;

[0011] Figure 2 This is a schematic diagram of the gas punch die. Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings. As shown in the drawings, the present invention includes a frame 4, on which two parallel guide rails 2 are provided, and multiple gas punches 1 are provided along the guide rails 2. In this embodiment, there are 9 gas punches 1, numbered 01-09, but other numbers of gas punches can be provided as needed.

[0013] The gas punch includes a base plate 10, a cylinder fixing plate 18 is provided above the base plate 10, and a cylinder 11 is fixed above the cylinder fixing plate 18; the piston end of the cylinder is connected to the upper mold of the mold 12, and the lower mold of the mold 12 corresponds to the upper mold; the bottom of the base plate 10 is fixedly connected to a locking slider 14; the locking slider 14 includes a groove 16, which corresponds to the guide rail 2; a screw hole is provided at the bottom of the groove, and a locking screw 17 is screwed into the screw hole. By rotating the locking screw 17, the locking screw 17 abuts against the guide rail 2, thereby fixing the locking slider 14 on the guide rail 2, and finally ensuring that the position of the gas punch on the guide rail is fixed.

[0014] The base plate 10 is fixed to the material support plate 15.

[0015] To enable the gas punch to be positioned perpendicular to the guide rail, a positioning plate 13 is also included; the positioning plate 13 is provided with an elongated groove 131, and the positioning screw 19 passes through the elongated groove to fix the positioning plate 13 to the side of the cylinder fixing plate 18.

[0016] To facilitate quick positioning, a scale 3 is installed below the guide rail on the side facing the staff.

[0017] An electrical control box 6 is installed at the front of the frame, and the electrical control box is connected to a foot switch 8; a gas distribution cylinder 7 is installed inside the frame, and the gas distribution cylinder is connected to the cylinder of each gas punching die through an electric control valve, which is connected to the electrical control box; a waste material receiving tray 5 is installed on the frame below the lower die.

[0018] Working principle of this utility model

[0019] When processing a certain type of fan coil unit, place the pneumatic punch die 1 (01-09) on the guide rail 2. Its position can be dragged and locked according to the hole spacing technical requirements of the part of that type.

[0020] The positioning plate can be adjusted forward and backward according to the workpiece requirements, thereby adjusting the position of the hole in the forward and backward direction.

[0021] The workpiece is placed on the support plate 15 and placed against the positioning plate 13 to perform the punching operation.

[0022] The same adjustment can be made when processing other models of fan coil units.

[0023] When punching, any set of dies from 01 to 09 can be selected (operation is controlled by switch 6 in the electrical control box). The operator can complete the operation by stepping on foot switch 8.

[0024] The punching diameter is determined by the requirements of the fan coil unit workpiece, and the punch of this die can be replaced with a punch of the required size at will.
