[0002] The existing hot forging presses usually have problems such as the mismatch between the workpiece material thickness and the forging die, the offset placement of the forging material, and insufficient forging pressure, which make it difficult to separate the upper and lower dies, and between the die and the workpiece, resulting in die jamming, leading to equipment operation failure and safety hazards. At the same time, the die change and installation in the existing technology takes a long time, and the die installation efficiency is low. Workers mostly load and unload the workpiece manually when the hot forging press is running, and the production efficiency is closely related to the workers' physical strength. In order to solve the above problems, a hot forging press device with a quick die release function is needed. Summary of the invention

[0005] When the present invention is working, the conveying unit clamps the workpiece to the mold unit, and then the spray unit sprays the release agent into the model cavity of the mold unit, which is convenient for the subsequent demolding of the mold unit and the workpiece and prevents the mold unit and the workpiece from sticking to each other, resulting in loss of the mold unit and the workpiece. Then the press body cooperates with the mold unit to forge the workpiece, and at the same time the press body drives the ejecting unit to eject the forged workpiece from the mold unit.

[0030] When the present invention is working, the conveying unit 4 clamps the workpiece to the mold unit 2, and then the spray unit 5 sprays the release agent into the model cavity of the mold unit 2, so as to facilitate the subsequent demolding of the mold unit 2 and the workpiece and prevent the mold unit 2 and the workpiece from sticking to each other, resulting in the loss of the mold unit 2 and the workpiece. Then the press body 1 cooperates with the mold unit 2 to forge the workpiece, and at the same time the press body 1 drives the ejecting unit 3 to eject the forged workpiece from the mold unit 2, and the conveying unit 4 clamps and conveys the formed workpiece.

The two side ends of the transmission slide 14 are slidably connected to the two fixed plates 13 respectively. The upper end of the transmission slider 14 is connected to the transmission unit 15, and a notch is provided at the bottom end of the transmission slider 14. Two positioning columns 17 are provided in the notch of the transmission slider 14. One end of the two positioning columns 17 extending out of the notch of the transmission slider 14 is provided with a through hole. The two positioning columns 17 pass through the mold unit 2, and the latch 16 passes through the through hole at one end of the two positioning columns 17. One end of the latch 16 contacts with the mold unit 2, and the transmission unit 15 passes through the shell 11. The transmission unit 15 is connected to the ejection unit 3 by transmission.

[0032] The transmission unit 15 drives the transmission slider 14 to slide between the two fixed plates 13, thereby driving the mold unit 2. The two positioning columns 17 on the transmission slider 14 pass through the mold unit 2, and then cooperate with the pin 16 to lock the mold unit 2. This method is more convenient and efficient than the traditional bolt connection method.

[0033] like Figure 1 and Figure 2 As shown, the transmission unit 15 includes a rotating motor 151, a transmission member 152, a pulley 153, a belt 154, a clutch 155, a transmission rod 156, a transmission gear 157, an eccentric crankshaft 158 ​​and a connecting rod 159.

[0040] The outer diameter of the inner planetary gear 34 is half of the inner diameter of the outer planetary gear 33 , and the central axis of the connection between the push rod 37 and the connecting block 36 falls on the pitch circle of the inner planetary gear 34 .

[0041] The outer diameter of the inner planetary gear 34 is half of the inner diameter of the outer planetary gear 33. The central axis of the connection between the ejector rod 37 and the connecting block 36 falls on the pitch circle of the inner planetary gear 34. The top end of the ejector rod 37 is inserted into the slideway 123 of the workbench 12, so that the two ends of the ejector rod 37 can perform a straight line reciprocating motion up and down. At the same time, a counterweight block 35 is provided to balance the center of gravity, which greatly reduces the overall vibration amplitude of the ejector unit 3. In addition, the ejector unit 3 can help the workpiece to be demolded in time to prevent the workpiece and the mold unit 2 from sticking.

Since the transmission slider 14 is slidably connected to the fixed plates 13 on both sides of the housing 11, it can only move up and down, and the eccentric crankshaft 158 ​​rotates. The movement can only drive one end of the connecting rod 159 connected to the transmission slider 14 to perform linear displacement up and down, thereby driving the transmission slider 14 to move up and down. The clutch 155 can indirectly control the frequency of die forging by controlling the rotation speed of the transmission rod 156. During die forging, the transmission slider 14 and the push rod 37 rise and fall at the same time. At the end of one die forging, along with the rise of the transmission slider 14, the push rod 37 lifts the die-forged workpiece, and the mechanical claw 43 clamps it for transportation. When the mechanical claw 43 clamps it, the nozzle 52 sprays a release agent into the model cavity of the upper mold 21 and the lower mold 22 to prepare for the next die forging.
