Description

Technical Field

[0001] The utility model relates to the technical field of drawing dies, in particular to a drawing die for an inner panel of a vehicle door. Background Art

[0002] Stamping dies are specialized equipment used in cold stamping to form parts. Stamping is a process whereby a die mounted on a press applies pressure to the material at room temperature, causing it to separate or plastically deform, thereby creating the desired part.

[0003] Stamping dies can be roughly divided into stretching dies and drawing dies. Stretching dies are for products with relatively regular shapes, such as pots, motor housings, etc. During the stamping process of such dies, the material will be stretched evenly and the yield rate is very high; drawing dies are for products with irregular shapes. During the stamping process, the material will not be stretched evenly, and wrinkles, cracks, and fractures will occur. Therefore, the yield rate of drawing dies is lower. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a vehicle door inner panel drawing die.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The utility model is further configured such that the punch structure includes: four punch slide rods, a punch base plate and a punch body; the four punch slide rods are respectively installed on the lower wall surface of the center plate, the punch base plate is installed on the lower wall surface of the four punch slide rods, and the punch body is movably sleeved on the outside of the four punch slide rods.

[0008] The utility model is further configured such that the die power structure includes: a die power support and a die power hydraulic device; the die power support is mounted on the upper wall of the die top plate, the die power hydraulic device is mounted inside the die power support, and the driving end of the die power hydraulic device passes through the die top plate and is connected to the die body.

[0009] The utility model is further configured such that the punch structure includes: a punch power support and a punch power hydraulic device; the punch power support is installed on the lower wall surface of the punch base plate, the punch power hydraulic device is installed inside the punch power support, and the driving end of the punch power hydraulic device passes through the punch base plate and is installed on the lower wall surface of the punch body.

[0010] The utility model is further configured that four supporting legs are installed on the lower wall surface of the punch bottom plate.

[0011] The utility model is further configured that a placement groove is provided on the upper wall surface of the middle plate.

[0012] The beneficial effects of the present invention are as follows: the present invention improves the stamping process of the drawing die, changing the original one-step forming into a two-step stamping forming. The first step is to punch the drawing ribs on the outside of the raw material and fix the outside of the raw material with a constant pressure. The second step is to perform drawing and stamping. Due to the fixation of the drawing ribs, the material will be evenly stretched during the drawing and stamping, thereby improving the product yield. BRIEF DESCRIPTION OF THE DRAWINGS
