Problems solved by technology
It can be seen that this method of disassembling the wedge assembly under the production line is very unreasonable, and the disassembled wedge assembly needs to be installed again when producing another stamping part with side punching state next time
The time for mold change is greatly increased, which greatly reduces production efficiency

Embodiment Construction
[0023] Such as Figure 1 ~ Figure 2 A switchable suspension wedge mechanism is shown, including a driving block 8, an upper die sliding block 4 sliding on the driving block 8, the upper die sliding block 4 is connected with the side punching punch 2, and the upper die sliding block 4 The top of the drive block 8 is connected to the upper mold base, one end of the drive block 8 is provided with a wedge guide plate 12, the other end of the drive block 8 is connected to the return mechanism, and the wedge guide plate 12 is pushed by the extrusion force of the telescopic mechanism The drive block 8 at the initial position slides forward and presses the return mechanism; when the telescopic mechanism removes the force exerted on the oblique guide plate 12 of the wedge, the return mechanism drives the drive block 8 to slide backward to the initial position. The telescoping mechanism includes a cylinder assembly 14 and a cylinder inclined guide plate 13 driven by the cylinder assembl...

The invention discloses a switchable suspension wedge mechanism and a use method thereof. The mechanism comprises a driving block, and an upper die sliding block sliding on the driving block, wherein the upper die sliding block is connected with a side piercing punch, the top end of the upper die sliding block is connected with an upper die seat, a wedge oblique guide plate is arranged at one end of the driving block, the other end of the driving block is connected with a return mechanism, and the wedge oblique guide plate pushes the driving block in an initial position to slide in the forward direction and oppresses the return mechanism under the extrusion acting force of a telescoping mechanism. By adopting the structure and the method, the mechanism and the use method have the following advantages: stamped parts in different states can be machined just by switching the state of a suspension wedge on a production line, thus saving time for dismounting a suspension wedge assembly from the production line, greatly saving time for changing dies, and greatly increasing the production efficiency.
Description
technical field [0001] The invention relates to the technical field of cold stamping of automobile cover parts, in particular to a switchable suspension wedge mechanism and a use method thereof. Background technique [0002] Stamping dies for automobile body panels are the most demanding and difficult to process in the manufacture of automobile bodies, and are also the rapidly developing cold stamping process equipment in the manufacture of electromechanical stamping parts in my country. In stamping dies for automobile panels, when stamping parts in different states are processed by switching the state of the suspension wedge on the same set of molds, the traditional suspension wedge mechanism can only be realized by disassembling the wedge assembly under the production line. This way of disassembling the wedge assembly off-line is very unreasonable, and the disassembled assembly needs to be installed again when the stamping part of another state is produced next time. As a...
