[0049] Example 1

[0050] In this embodiment, Figure 1-Figure 8 Given, the present invention provides the following technical solutions:

[0051] A wrench blank precision die forging forming device, comprising a heating furnace 1 and a blank, wherein the blank is heated in the heating furnace 1, and the heating furnace 1 is used to heat the blank to a temperature suitable for forging to improve its plasticity and reduce deformation resistance, so as to facilitate subsequent die forging forming, and further comprising a feed pipe 2, a conveying device 3, a first manipulator 5 and a rough forging device 6;

[0052] The feeding tube 2 is tilted, with one end higher and the other lower. The heated blank will slide down the feeding tube 2 onto the conveying device 3, and the tilted design of the feeding tube 2 ensures the smooth sliding of the blank. The higher end is connected to the heating furnace 1, and the lower end is connected to the conveying device 3. The feeding tube 2 is provided with a heat preservation cover, which is made of high temperature resistant and heat-insulating materials to reduce heat loss and maintain the temperature of the blank during transportation.

[0053] The conveying device 3 includes a first conveyor 31, which is arranged at the lower end of the discharge pipe 2 and is used to receive the blanks dropped from the heating furnace 1. The first conveyor 31 conveys the heated blanks from the heating furnace 1 through a steel conveyor belt or chain transmission mechanism, and the power source is a motor. By adjusting the speed of the motor, the conveying speed can be adjusted to meet the needs of different production rhythms. The first conveyor 31 is provided with a clamping device 32 and a counting device. The counting device is used to record the number of blanks, and the clamping device 32 is used to limit and clamp the blanks on the first conveyor 31;

[0054] The first manipulator 5 is arranged behind the right side of the conveying device 3, and the rough forging device 6 is arranged on the right side of the first manipulator 5. The rough forging device 6 is used for die forging of the blank, and the first manipulator 5 is used for clamping and transferring the blank.

[0055] The clamping device 32 is provided with two, which are relatively arranged on the front and rear sides of the first conveyor 31, and the clamping device 32 includes a clamping cylinder 321, and the output end of the clamping cylinder 321 is provided with a clamping plate 322, and the clamping plate 322 is horizontally arranged and parallel to the first conveyor 31; the clamping cylinder 321 drives the clamping plate 322 to limit and clamp the blank to prevent the blank from displacement or slipping during the transmission process, and the clamping force can be adjusted according to the size and weight of the blank. When the blank contacts the pressure sensor 42 on the limit block 41, the pressure sensor 42 receives a signal and sends a signal command to the clamping cylinder 321, and the clamping cylinder 321 drives the clamping plate 322 to move, thereby clamping the blank. At the same time, after clamping, the first manipulator 5 will also receive an instruction to pick up the clamped blank and transfer it to the lower die 62 in the rough forging device 6 for the initial forging process;

[0056] A connecting plate 323 is provided at the bottom of the clamping plate 322, and the connecting plate 323 is fixedly connected to the clamping plate 322 by a bolt 45 fastener.

After the work is completed, the clamping device 32 can be started to clean the first conveyor 31. The clamping cylinder 321 reciprocates to contract the clamping plate 322, thereby driving the bristles 324 under the connecting plate 323 to clean back and forth on the surface of the first conveyor 31 to clean up the impurities remaining on it, and at the same time, the subsequent suction device 4 will be started. After the impurities are cleaned up, they will be absorbed into the dust box 47 through the suction device 4, thereby achieving the purpose of cleaning, ensuring the cleanliness of the device and improving the working environment.

Heating step: placing the blank into a heating furnace and heating the blank to a temperature range suitable for forging by electromagnetic induction or resistance heating; S2, conveying and positioning step: the heated billet slides onto the conveying device through the feeding tube, and the conveying device conveys the billet to the entrance position of the rough forging device, and the pressing device limits and presses the billet to ensure the stability and accuracy of the billet during the conveying process; S3, rough forging step: the first manipulator grabs the blank from the conveying device and places it between the upper die and the lower die of the rough forging device, and the die forging hydraulic cylinder drives the upper die to move downward to perform die forging on the blank to form a preliminary wrench blank; S4, trimming processing step: the second manipulator transfers the rough forged billet to the trimming device, and the trimming hydraulic cylinder drives the trimming upper die to move downward to perform trimming operations on the billet to remove excess edge material generated during the forging process. At the same time, the cleaning device cleans the trimming device to ensure the cleanliness and sanitation of the trimming device; S5, product transfer step: the third robot takes out the trimmed blank from the trimming device and transfers it to the subsequent process for further processing or testing.
