Embodiment 1

[0041] An automatic cooling and lubricating device for a forging die of this embodiment, wherein the die is such as figure 1 , figure 2As shown, it includes upper die base 1, lower die base 2, upper die 4, lower die 6 and punch 3, upper die base 1 and upper die 4, lower die base 2 and lower die 6 are connected by spring 8 , the forging is evenly stressed during forging; the upper mold cavity 5 is opened in the upper mold 4, and the lower mold cavity 7 is opened in the lower mold 6. When the mold is closed, the upper mold cavity 5 and the lower mold cavity 7 form a complete mold. cavity. The cooling and lubricating device of this embodiment is provided with two groups symmetrically on both sides of the mould, further ensuring sufficient cooling and lubrication of the upper mold cavity 5 and the lower mold cavity 7, wherein each group of lubricating devices includes a nozzle 16, a pushing device and a fixing device, The nozzle 16 is arranged on the fixing device and extends t...

Embodiment 2

[0058] An automatic cooling and lubricating device for a forging die in this embodiment has the same basic structure as in Embodiment 1. Further, in this embodiment, the inclined push rod 902 includes a transverse extension and a connecting rod 903, such as Figure 7 As shown, the height of the transverse extension section rises gradually along the direction away from the mold, and its highest end is connected with the connecting rod 903 in an arc transition. The connecting rod 903 extends upward and the angle α between the horizontal plane is not greater than 90°. The total length L3 of the horizontal projection of the extension section and the connecting rod 903 is greater than the distance L1 from the outer wall of the lower mold 6 to the inner wall of the lower mold cavity 7, and the total length L4 of the vertical projection of the lateral extension section and the connecting rod 903 is greater than the upper mold in the initial state. 4 The vertical distance L2 from the l...

Embodiment 3

[0060] An automatic cooling and lubricating device for a forging die in this embodiment has the same basic structure as that in Embodiment 2, except that the inclined push rod 902 in this embodiment includes a transverse extension and a connecting rod 903, such as image 3 As shown, the angle α between the connecting rod 903 and the horizontal plane is 90°, that is, the connecting rod 903 is a vertical rod connected to the high end of the horizontal extension section. Correspondingly, the horizontal projection total length L3 of the horizontal extension section is greater than that of the lower mold 6 The distance L1 from the outer wall to the inner wall of the lower mold cavity 7, the sum L4 of the vertical projection length of the lateral extension section and the length of the connecting rod 903 is greater than the vertical distance L2 from the lower end surface of the upper mold 4 to the upper end surface of the nozzle 16 in the initial state, and the vertical distance L2 T...

Abstract

The invention discloses an automatic cooling and lubricating device for a forging die, and belongs to the technical field of metal press working. The device comprises a spray nozzle, a pushing device and a fixing device. The spray nozzle is arranged on the fixing device, and extends to a die. The pushing device is used for pushing the fixing device to do retracting motion. When the an upper die and a lower die of the die are made, the pushing device pushes the fixing device to extend to the direction approaching the die. The spray nozzle protrudes into the space between an upper die cavity and a lower die cavity for cooling and lubricating. When the upper die and the lower die are combined, the pushing device pushes the fixing device to extend to the direction away from the die, and the spray nozzle backs out of the upper die and the lower die. The automatic cooling and lubricating device for the forging die overcomes the shortcomings that in the prior art, the automation level and work efficiency of the cooling and lubricating of the forging die are low, the work efficiency is effectively increased and the temperature is effectively reduced. The structure is simple, the use is convenient, and the temperature reduction is uniform.

Description

technical field [0001] The invention relates to the technical field of metal pressure processing, in particular to an automatic cooling and lubricating device for a forging die. Background technique [0002] When hot forging blanks, since the temperature of the hot forging upper die and hot forging lower die is very high during the hot forging process, excessively high temperature can reduce the hardness of the die and affect its strength, so it must be timely Cool it down and lubricate it. The current cooling method for forging molds is: use a long rod nozzle, hold it manually, extend the nozzle between the hot forging upper die and the hot forging lower die, first spray the nozzle towards the hot forging lower die to cool down with graphite emulsion, Then turn the nozzle over, so that the nozzle faces the hot forging upper die and sprays the graphite emulsion liquid to cool. The deficiency of this spray solution cooling method is: low working efficiency; slow cooling spe...
