Description

Technical Field

[0001] The present invention relates to the technical field of forging and pressing, and more particularly to a novel hydraulic press for ring forging. Background Art

[0002] Ring forging blanking refers to flange or cylindrical forgings, which are first flattened, then punched out with a smaller inner hole, and then expanded and formed on a ring rolling machine. The entire production line consists of blank making equipment and ring rolling machines. Traditional ring forging blank making equipment is completed by a free forging hydraulic press, which first flattens, then uses a swing arm mechanism to rotate the punch to the center position, then presses down to punch, then turns the pancake forging over, and then punches out the skin. The entire process takes about 1 minute, and the production efficiency is relatively low.

[0003] Among them, the patent with publication number CN208913049U discloses a multi-station ring forging billet hydraulic press, which includes a main body, a final punching device, a roughing upper die, a pre-punching punch and a final punching punch; the main body includes a slider and a workbench arranged relatively, and the roughing upper die and the pre-punching punch are respectively installed on the roughing and pre-punching upper die switching device and are installed at the bottom of the slider through the roughing and pre-punching upper die switching device.

[0004] When the structure is in use, a first lower anvil is arranged on the workbench. As the upsetting and pre-punching upper die switching device is switched, the upsetting upper die and the pre-punching punch are alternately fixed to the final punch device opposite to the first lower anvil on one side of the main body, and the final punch is fixed on the final punch device. However, when forging, it is not easy for the punch to completely separate from the die. The high-intensity operation reduces the life of the punch, and the accuracy and stability during forging cannot be ensured, which easily leads to reduced product quality. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a new type of ring forging hydraulic press, which aims to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a new type of ring forging hydraulic press, comprising a base, on which a forging assembly is arranged.

[0007] The forging assembly includes a supporting box body arranged on the top of the base, a plurality of forging chambers are penetrated through the supporting box body, a horizontal plate is fixedly provided on one side of the surface of the base, a workbench is installed on the horizontal plate by bolts, a plurality of nesting rods are provided on one side of the workbench, and each of the nesting rods is plugged into the horizontal plate.

[0008] An upper press is provided on the top of the support box body, and a pressure head is provided at the output end of the upper press, and the pressure head is located at the top of the inner cavity of the forging chamber, and a slide rail is fixedly provided at the bottom of the pressure head, and a reinforced support slide plate is slidably connected to the bottom of the slide rail, and a pad is fixedly provided at the bottom of the reinforced support slide plate, and a plurality of springs are distributed at the bottom of the pad, and a pressure plate is fixedly provided at the bottom of each spring, and a reinforced central supporting ejector rod is inserted in the middle of the pad, and a plurality of electromagnets are distributed on the outer side of the reinforced central supporting ejector rod, and each of the electromagnets is fixed on the pad, and an electric push rod is installed on one side of the pressure head by bolts, and the output end of the electric push rod extends to one side of the reinforced support slide plate and is detachably connected to the reinforced support slide plate by bolts.

[0009] It can be seen that in the above technical scheme, the upper press is started to drive the pressure head, the slide rail and the reinforced support slide plate to move downward, and the electric push rod is started to drive the reinforced support slide plate to slide on the slide rail for position adjustment, so that the pressure plate and the reinforced center support push rod can be located on the top of the workpiece, and the reinforced support slide plate continues to move downward to flatten the forging, and the pressure plate is forced to fit the workpiece and compress the spring, which first plays a leveling function when forging the workpiece, so that the workpiece can be placed horizontally to avoid poor forming quality of the workpiece, and the punch is driven by the lower press to move upward and penetrate the connecting seat and the punch cylinder to punch the workpiece, and then return after punching is completed to avoid the punch heating up due to too long a dwelling time, and the reinforced center support push rod adsorbs the waste material after punching during punching, and the pressure plate pushes out the waste material adsorbed on the reinforced center support push rod through the elastic drive of the spring itself.

[0010] A punch is arranged below the reinforced central supporting ejector rod, a tray is sleeved on the outer side of the punch, a lower press is arranged at the bottom of the support box, a punch is arranged at the output end of the lower press, a connecting seat is inserted at the bottom of the punch, the punch passes through the connecting seat and the punch and extends to the top of the punch, a plurality of cylinders are distributed on the outer side of the pallet, and each of the cylinders is installed on the top of the connecting seat through a column, a plurality of ejector rods are fixedly arranged at the output ends of the cylinders, and a reinforced L-pull plate is threadedly connected to one end of each of the ejector rods, the reinforced L-pull plate is located on the upper surface of the pallet, a limiting arc groove is provided at the bottom of the reinforced L-pull plate, and the cross-sectional shape of the limiting arc groove is arc-shaped, a reinforced support frame is installed at the bottom of the connecting seat by bolts, the reinforced support frame is located at the bottom of the inner cavity of the forging chamber, and the reinforced support frame is detachably connected to the support box by bolts.

[0011] It can be seen that in the above technical solution, the pallet first positions the workpiece, and the cylinder is started to drive the push rod to drive the reinforced L-pull plate to move. The reinforced L-pull plate is in contact with the outside of the workpiece and the workpiece is lifted up by the traction force of the reinforced L-pull plate. The bottom of the reinforced L-pull plate can extend to the bottom of the workpiece, so that the workpiece can ensure the stability during forging and there is a certain gap between it and the punch cylinder, and it fits with the bottom of the workpiece through the limiting arc groove to avoid the phenomenon when the workpiece is pressurized at the bottom and top at the same time.

[0012] Technical effects and advantages of the present invention:

[0013] 1. The present invention starts the upper press to drive the pressure head, the slide rail and the reinforced support slide plate to move downward, and starts the electric push rod to drive the reinforced support slide plate to slide on the slide rail for position adjustment, so that the pressure plate and the reinforced central support push rod can be located on the top of the workpiece, making it easy for the reinforced support slide plate to continue to move downward to flatten the forging;

[0014] 2. In the present invention, when forging, the pressure plate is pressed against the workpiece and the spring is compressed, which firstly plays a leveling function on the workpiece during forging, so that the workpiece can be placed horizontally, thus avoiding poor forming quality of the workpiece;

[0015] 3. The present invention makes the workpiece lifted up by the traction force of the reinforced L-pull plate by contacting the outside of the workpiece and displacing the workpiece, so that the bottom of the reinforced L-pull plate can extend to the bottom of the workpiece, so that the workpiece can ensure stability during forging, and a certain gap exists between it and the punch cylinder, and fits with the bottom of the workpiece through the limiting arc groove, so as to avoid displacement of the workpiece when the bottom and top are pressurized at the same time;

[0016] 4. The present invention drives the punch to move upward through the lower press and penetrates the connecting seat and the punch barrel to punch the workpiece, and then returns after the punching is completed to avoid the punch heating up due to a long dwell time. During the punching, the center support push rod is strengthened to absorb the waste material after the punching is completed, and the pressure plate pushes out the waste material absorbed on the center support push rod through the elastic drive of the spring itself;

[0017] To sum up, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the electric push rod drives the reinforced support slide plate to slide on the slide rail for position adjustment, so that the pressure plate and the reinforced center support push rod can be located on the top of the workpiece, which is easy to strengthen the support slide plate to continuously move downward to flatten the forging, and the pressure plate is forced to fit the workpiece and the spring is compressed. First, it plays a leveling function when forging the workpiece, so that the workpiece can be placed horizontally to avoid poor workpiece forming quality. The bottom of the reinforced L-pull plate can extend to the bottom of the workpiece, so that the workpiece not only ensures the stability during forging, but also has a certain gap between it and the punch cylinder, and fits with the bottom of the workpiece through the limiting arc groove to avoid the workpiece from shifting when the bottom and top are pressurized at the same time, and the punch is retracted after punching is completed to avoid the punch heating up due to too long a dwelling time, and the reinforced center support push rod adsorbs the waste material after punching during punching, and the pressure plate pushes out the waste material adsorbed on the reinforced center support push rod through the elastic drive of the spring itself, which is easy for the device to run continuously.
