Technical Field
[0001] The utility model relates to the technical field of mechanical manufacturing equipment, in particular to an oblique punch component and a punching die. Background Art
[0002] For automobile assemblies, many parts such as front and rear doors, engine hoods, and trunk lids are all drawn parts. Due to the process of forming after flat punching, convex hulls and bends are prone to occur, which affect the precision of automobile assemblies and make it difficult to ensure the forming stability of automobile assemblies. At present, the process steps of first forming and then bevel punching are often used.
[0003] Generally, there is an angle of about 5° between the axis of the punched part and the punched hole. Therefore, it is necessary to customize the inclined slider, inclined wedge structure, etc. according to the stamped part. However, since the inclined wedge structure is relatively complex and has high production cost, it is also necessary to reserve a larger space for the inclined wedge structure in the stamping die, which makes the time cost and economic cost of the preliminary preparation of the punching high.

[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0037] For the convenience of subsequent description, before describing the specific structure of the oblique punch assembly 10, the present application first Figure 1 A first direction (Z) and a second direction (X) are defined. The first direction is the height direction of the oblique punch assembly 10 when it is normally placed, such as the Z direction; the second direction is the width direction of the oblique punch assembly 10 when it is normally placed, such as the X direction. In this application, the first direction (Z) and the second direction (X) are perpendicular to each other.
[0038] It can be understood that the mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity caused by processing errors and assembly errors (for example, the angle between two structural features is 89.9°) is also within the range of mutual perpendicularity in the present application.
[0039] See also Figure 1 to Figure 2 As shown, Figure 1 The structure diagram of an embodiment of an oblique punch assembly 10 provided by the present application is shown. Figure 1 ; Figure 2 The structure diagram of an embodiment of an oblique punch assembly 10 provided by the present application is shown. Figure 2 ;in, Figure 1 to Figure 2 It is the stamping process of the oblique punch 11.
[0040] In some embodiments, the oblique punch assembly 10 includes an oblique punch head 11 , a first fixing portion 12 and a second fixing portion 13 .
[0041] The oblique punch 11 is used to perform a punching action; the first fixing portion 12 is provided with a clamping plate 120, and the clamping plate 120 is used to fix the oblique punch 11, wherein the oblique punch 11 is obliquely arranged in the clamping plate 120 along a first direction.
[0042] The second fixing portion 13 includes a guide plate 130 and a pressure plate 131. The guide plate 130 is fixed above the pressure plate 131 along the first direction and is movably connected to the clamping plate 120, so that when the first fixing portion 12 can move along the guide plate 130 toward the pressure plate 131, the oblique punch 11 can pass through the pressure plate 131 to perform a punching action.
[0043] In the embodiment of the present application, the oblique punch 11 is fixed by the first fixing portion 12. For example, the oblique punch 11 is embedded in the clamping plate 120, so that the oblique punch 11 can have a certain inclination angle along the first direction, so that during the stamping process, the oblique punch 11 can be perpendicular to the inclined surface of the part 30' to be stamped, and the inclined stamping action of the oblique punch 11 is changed to a vertical stamping action.
[0044] The first fixing part 12 and the second fixing part 13 are slidably matched to realize the punching action of the oblique punch 11, that is, the clamping plate 120 of the first fixing part 12 and the guide plate 130 of the second fixing part 13 are movably connected, so that the oblique punch 11 is pressed down to perform the oblique punching action, and the pressing plate 131 also has a unloading effect.
[0045] Compared with the prior art method of using an inclined wedge structure for oblique punching, the above-mentioned oblique punch assembly 10 has a simple structural design and can set the inclination angle of the oblique punch 11 according to the different inclination angles of different products, thereby controlling the appropriate stamping precision to perform the oblique punching action, effectively reducing the equipment cost in the large-scale stamping process.
