Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a sheet metal stamping device. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, thereby obtaining product parts with certain shapes, sizes and performances. Sheet metal, die and equipment are the three elements of stamping. According to the stamping temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing and also belongs to material forming engineering technology.

[0003] In the existing technology, the traditional stamping device is easy to cause the sheet metal to get stuck in the mold during the demoulding process after the sheet metal is stamped, which affects the demoulding efficiency and quality, and increases the risk of damage to the mold and sheet metal. Forced demoulding may cause damage to the sheet metal or the mold, thereby affecting the quality and precision of the product. This is especially important for parts that require high-precision processing, and the lack of automated design makes it impossible to achieve efficient and continuous demoulding operations, which restricts the efficiency improvement in large-scale production.

[0024] Example 1

[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a sheet metal stamping device, comprising: a stamping mechanism 1, a convenient disassembly mechanism 2 is arranged on the top side of the stamping mechanism 1, the stamping mechanism 1 comprises a lower die 14, an inner plate 15 is arranged on the inner wall of the lower die 14, the inner wall of the lower die 14 is vertically matched with the outer side of the inner plate 15, a transverse plate 17 is arranged on the bottom of the inner plate 15, the bottom of the inner plate 15 is fixedly contacted with one end of the top side of the transverse plate 17, a linear groove 18 is opened on the inner wall of the transverse plate 17, a connecting arm 19 is arranged on the inner surface of the linear groove 18, the inner surface of the linear groove 18 is slidably connected with one end of the connecting arm 19, a telescopic rod 110 is arranged on the bottom side of the lower die 14, the bottom side of the lower die 14 is fixedly connected with the outer side of the telescopic rod 110, one end of the telescopic rod 110 is fixedly connected with one side of the connecting arm 19, the lower die 14 A connecting rod 112 is provided on the bottom side, the bottom side of the lower mold 14 is fixedly connected to the top end of the connecting rod 112, the outer side of the connecting rod 112 is vertically slidably connected to one end of the side of the cross plate 17, the bottom end of the connecting rod 112 is fixedly connected to the top side of the pedestal 11, the top inner wall of the pedestal 11 vertically corresponds to one end of the column 111, the other end of the column 111 is fixedly connected to the bottom side of the lower mold 14, a stamping device 12 is provided at one end of the pedestal 11, one end of the pedestal 11 is fixedly connected to one side of the stamping device 12, an upper mold 13 is provided at one end of the stamping device 12, one end of the stamping device 12 is fixedly connected to the top side of the upper mold 13, a steel block 16 is provided on the bottom side of the inner plate 15, the bottom side of the inner plate 15 is fixedly connected to the top of the steel block 16, and the bottom end of the steel block 16 contacts the inner wall of the lower mold 14.

[0026] In this embodiment, when the sheet metal stamping device is in use, in order for the sheet metal to be able to smoothly leave the mold after the stamping is completed, the object is placed in the lower mold 14, and then the upper mold 13 is used to stamp the object in the lower mold 14 through the stamping equipment 12. When the stamping is completed, the telescopic rod 110 is extended, so that the connecting arm 19 moves in the linear slot 18 in the horizontal plate 17, and the trajectory of the linear slot 18 is presented in a Z shape. Since the connecting arm 19 moves horizontally, the horizontal plate 17 will gradually be raised in height during the movement.

[0030] In this embodiment, since the bottom side structure of the lower mold 14 is relatively large, in order to facilitate maintenance, the locking rod 23 is removed from the card plate 21 to release the control of the card plate 21, and then the card plate 21 is pushed in the side plate 22 until it is pushed to the end of the side plate 22. In this way, the card plate 21 will not be buckled on the column 111. Since the column 111 and the lower mold 14 are integrated, the lower mold 14 can be removed from the base 11 once the column 111 is not restricted. This operation allows maintenance personnel to easily remove the lower mold 14 from the base 11 for maintenance, replacement or cleaning.
