[0013] In order to more clearly illustrate the technical scheme in the embodiments of the present application or the prior art, the drawings needed in the embodiment or prior art description will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor on the basis of these drawings.

[0014] Figure 1 The main body schematic diagram of the heating plate mounting hole punching device of the passenger car electric heater of the present application is composed of a measuring stop plate (1), an upper mold mounting plate (2), a punch (3), a punching hole (4), a lower mold front end convexity (5), a lower mold clamping plate (6), a lower mold base plate (7), a trapezoidal plane (8) and a trapezoidal plane (9). DETAILED DESCRIPTION

[0015] All features disclosed in this specification, or the steps of any method or process specified in this specification, can be combined in any manner, except where features or steps are mutually exclusive.

[0016] Any feature disclosed in this specification, unless otherwise stated, can be replaced by an alternative feature or step having the same or similar effect. That is, unless stated otherwise, each feature is merely one example of a range of equivalent or similar features.

[0017] In the description of this utility model, it should be understood that the terms "bottom surface," "front surface," "middle point," "one end surface," "below," "both ends," "both sides," "outer end," and "relative," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the terms "set," "fasten," and "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection; or an indirect connection through an intermediate medium, unless otherwise expressly limited. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0018] like Figure 1 As shown, this utility model is a stamping device for the heating plate mounting hole of a bus electric heater. The stamping device consists of a side baffle (1), a punch (3), an upper mold mounting plate (2), a clamping plate (6), and a lower mold base plate (7).

[0019] The upper die mounting plate (2) and the punch (3) are integrally formed. The upper die mounting plate (2) is mechanically connected to the moving parts of the punch press. The bottom of the lower die base plate (7) is pressed and connected to the punch press.

[0020] The upper die punch (3) is set in an elliptical shape and fits with the punch hole (4) of the lower die clamping plate. Its material is designed as high-speed steel, which has good wear resistance and toughness. The punch is not easy to break or wear, which can effectively increase production and greatly meet production needs.

[0021] The lower mold body is connected to the lower mold base plate (7) by a clamping plate (6) with internal hex bolts, which facilitates mold processing and subsequent disassembly and maintenance.

[0022] The lower die clamping plate (6) is convex in design. The upper part of the convex surface is convenient for observing the stamping of the heating plate. The space between the lower part and the trapezoidal plane (8) is designed to be the same size as the edge thickness of the heating plate that needs to be punched (the thickness and width of all heating plate punching edges are the same). The edge of the heating plate that needs to be punched is embedded in the middle of the lower part of the convex surface and the trapezoidal plane (8). When the punch (3) passes through the elliptical hole in the middle between the punch (4) and the trapezoidal plane (8), the mounting hole of the heating plate edge can be punched. The side baffle (1) can be adjusted left and right to move the heating plate left and right, which can change the position of the heating plate punching. The heating part of the heating plate is placed on the trapezoidal plane (9) of the lower die base plate (7) so that the heating part of the heating plate is placed horizontally on the trapezoidal plane (9) to avoid uneven deformation due to stress, which would affect the performance of the heating plate.

[0023] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement not through creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
