[0003] According to the processing requirements of different workpieces, when going from the first die hole to the second die hole, the workpiece needs to be rotated 0 degrees or 90 degrees or 180 degrees, (for example, ordinary nuts need to be rotated 180 degrees, some special-shaped nuts need to be rotated 90 degrees, and some bolts The stamping does not need to rotate), the existing clamping device can only meet one clamping condition, for example, the patent number is CN201710439167.1, the patent name is a material clamping device for cold heading machine and the patent number is CN201420212438 .1 The patent name is a patent for a flipping clamp mechanism on a cold heading machine. When the rotation angle of the workpiece changes, it takes a long downtime to replace the clamping device, and continuous debugging is required. The operation is cumbersome and seriously affects production. Efficiency, use cost and manufacturing cost are relatively high; the existing gripper cannot complete the working condition of 90-degree rotation, the use range is narrow, and the practicability is low

The invention discloses a multi-station transfer device for blanks of a nut cold heading machine. The beneficial effect of the present invention is that, through the function of the blank transfer mechanism, the gripper holding the blank can be adapted to various working conditions, and the clamping device can be rotated at 0 degrees, 90 degrees, 180 degrees through the function of the working condition switching mechanism. Quickly switch between degrees to meet the needs of different working conditions, improve the practicability of the clamping device, reduce the cost of use and manufacturing, and improve production efficiency.
Description
technical field [0001] The invention relates to the technical field of moving blanks of cold heading machines, in particular to a multi-station transfer device for blanks of cold heading machines for nuts. Background technique [0002] The cold heading machine is a forging and forming equipment that thickens the bar under normal temperature conditions; the cold heading machine uses the cold heading method to form nuts and screw holes; it is directly formed into the required shape and size, reducing cutting work and saving a lot of material. At the same time, the production efficiency is greatly improved. The processing steps of the cold heading machine generally include feeding, cutting, upsetting, and discharging. Upsetting uses a clamping device to transfer the blank between adjacent molds, and then each front Forming is completed after punching and stamping; [0003] According to the processing requirements of different workpieces, when going from the first die hole to t...
