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 on one side of the main body with the final punch device opposite to the first lower anvil. 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] A upper press is arranged on the top of the supporting box body. A punch head is arranged at the output end of the upper press. The punch head is located at the top of the inner cavity of the forging chamber. A slide rail is fixedly arranged at the bottom of the punch head. A reinforced support slide plate is slidably connected to the bottom of the slide rail. A cushion plate is fixedly arranged at the bottom of the reinforced support slide plate. A plurality of springs are distributed at the bottom of the cushion plate, and the bottom of each spring is fixedly provided with a pressing plate. A reinforced center supporting and feeding ejector rod is inserted into the middle of the cushion plate. A plurality of electromagnets are distributed on the outer side of the reinforced center supporting and feeding ejector rod, and each electromagnet is fixed on the cushion plate. An electric push rod is installed on one side of the punch head through bolts. 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 through bolts.

[0009] It can be seen that in the above technical solution, the upper press is started to drive the punch head, the slide rail and the reinforced support slide plate to move downward. 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 pressing plate and the reinforced center supporting and feeding ejector rod can be located at the top of the workpiece. The reinforced support slide plate continues to move downward to flatten the forging. The pressing plate is stressed and fits with the workpiece, causing the spring to compress. It first plays a leveling function when forging the workpiece, enabling the workpiece to be placed horizontally and avoiding poor forming quality of the workpiece. The lower press is driven to move the punch head upward through the connecting seat and the punching cylinder to punch the workpiece. After punching is completed, it retreats to avoid overheating of the punch head due to too long staying time. During punching, the reinforced center supporting and feeding ejector rod adsorbs the waste after punching, and the pressing plate drives the waste adsorbed on the reinforced center supporting and feeding ejector rod to be pushed out through the elasticity of the spring itself.

[0010] A punching cylinder is arranged below the reinforced center supporting and feeding ejector rod. A tray is sleeved outside the punching cylinder. A lower press is arranged at the bottom of the supporting box body. A punch head is arranged at the output end of the lower press. A connecting seat is inserted into the bottom of the punching cylinder. The punch head penetrates through the connecting seat and the punching cylinder and extends to the top of the punching cylinder. A plurality of cylinders are distributed outside the tray, and each cylinder is installed on the top of the connecting seat through a column. The output ends of a plurality of cylinders are fixedly provided with ejector rods, and one end of each ejector rod is threadedly connected with a reinforced L-shaped pull plate. The reinforced L-shaped pull plate is located on the upper surface of the tray. A limiting arc groove is formed at the bottom of the reinforced L-shaped pull plate. 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 through bolts. The reinforced support frame is located at the bottom of the inner cavity of the forging chamber. The reinforced support frame is detachably connected to the supporting box body through bolts.

[0011] It can be seen that in the above technical solution, the tray first positions the workpiece, starts the cylinder to drive the ejector rod to drive the reinforced L-shaped pull plate to displace, the reinforced L-shaped pull plate abuts against the outside of the workpiece and causes the workpiece to be lifted by the traction force of the displacement of the reinforced L-shaped pull plate, so that the bottom of the reinforced L-shaped pull plate can extend to the bottom of the workpiece, ensuring the stability of the workpiece during forging and pressing, and there is a certain gap between the workpiece and the punching cylinder, and it is in contact with the bottom of the workpiece through the limiting arc groove, avoiding the displacement of the workpiece when it is pressed simultaneously from the bottom and the top.

[0012] The technical effects and advantages of the present invention:

[0013] 1. In the present invention, by starting the upper press to drive the pressure head, the slide rail and the reinforced support slide plate to displace downward, and starting the electric push rod to drive the reinforced support slide plate to slide on the slide rail for position adjustment, the pressure plate and the reinforced central material supporting ejector rod can be located at the top of the workpiece, which is conducive to the continuous downward displacement of the reinforced support slide plate to flatten the forging.

[0014] 2. While the forging and pressing are carried out in the present invention, the pressure plate is stressed and abuts against the workpiece, causing the spring to compress, which first plays a leveling function during the forging and pressing of the workpiece, enabling the workpiece to be placed horizontally and avoiding poor forming quality of the workpiece.

[0015] 3. In the present invention, the reinforced L-shaped pull plate abuts against the outside of the workpiece and causes the workpiece to be lifted by the traction force of the displacement of the reinforced L-shaped pull plate, so that the bottom of the reinforced L-shaped pull plate can extend to the bottom of the workpiece, ensuring the stability of the workpiece during forging and pressing, and there is a certain gap between the workpiece and the punching cylinder, and it is in contact with the bottom of the workpiece through the limiting arc groove, avoiding the displacement of the workpiece when it is pressed simultaneously from the bottom and the top.

[0016] 4. In the present invention, the lower press drives the punch to displace upward and penetrate through the connecting seat and the punching cylinder to punch the workpiece. After punching is completed, it retracts, avoiding overheating of the punch due to too long residence time. And during punching, the reinforced central material supporting ejector rod adsorbs the waste material after punching, and the pressure plate drives the waste material adsorbed on the reinforced central material supporting ejector rod to be ejected through the elasticity of the spring itself.

[0017] In summary, the overall design is simple and the structure is reasonable. Through the coordinated use 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 central blank holding ejector rod can be located at the top of the workpiece, which is conducive to the continuous downward displacement of the reinforced support slide plate to flatten the forging. When the pressure plate is stressed and fits with the workpiece, the spring is compressed, which first plays a leveling function when forging the workpiece, enabling the workpiece to be placed horizontally, avoiding poor forming quality of the workpiece. The bottom of the reinforced L-shaped plate can extend to the bottom of the workpiece, ensuring the stability of the workpiece during forging and leaving a certain gap between the workpiece and the punching cylinder. And it fits with the bottom of the workpiece through the limit arc groove, avoiding the displacement of the workpiece when it is pressed simultaneously from the bottom and the top. After punching, the punch retracts, avoiding the punch from overheating due to too long residence time. During punching, the reinforced central blank holding ejector rod adsorbs the waste after punching, and the pressure plate drives the waste adsorbed on the reinforced central blank holding ejector rod out through the elasticity of the spring itself, which is conducive to the continuous operation of the device.

[0033] As shown in the attached Figure 1 - Figure 7A new type of ring forging blank hydraulic press shown in the figure. Through the forging component arranged on the base 1, the electric push rod 210 drives the reinforced support slide plate 203 to slide on the slide rail 202 for position adjustment, so that the pressure plate 206 and the reinforced central blank holding ejector rod 207 can be located at the top of the workpiece, which is conducive to the continuous downward displacement of the reinforced support slide plate 203 to flatten the forging. When the pressure plate 206 is stressed and fits with the workpiece, the spring 205 is compressed, which first plays a leveling function during the forging of the workpiece, enabling the workpiece to be placed horizontally and avoiding poor forming quality of the workpiece. The bottom of the reinforced L-shaped pull plate 304 can extend to the bottom of the workpiece, ensuring the stability of the workpiece during forging and leaving a certain gap between the workpiece and the punching cylinder 3. And it fits with the bottom of the workpiece through the limit arc groove 305, avoiding the displacement of the workpiece when it is pressurized from both the bottom and the top. After punching, the punch 308 retracts to avoid overheating of the punch 308 due to too long residence time. During punching, the reinforced central blank holding ejector rod 207 adsorbs the waste after punching, and the pressure plate 206 drives the waste adsorbed on the reinforced central blank holding ejector rod 207 out through the elasticity of the spring 205 itself, which is conducive to the continuous operation of the device. The specific structure of the components is as follows;

[0034] The forging component includes a support box body 101 arranged on the top of the base 1. A number of forging chambers 102 are penetrated through the support box body 101. A cross plate 103 is fixedly arranged on one side of the surface of the base 1. A workbench 104 is installed on the cross plate 103 through bolts. A number of nesting rods 105 are arranged on one side of the workbench 104, and each nesting rod 105 is inserted into the cross plate 103.

[0035] At the top of the support box body 101, there is an upper press 2. At the output end of the upper press 2, there is a punch head 201. The punch head 201 is located at the top of the inner cavity of the forging chamber 102. At the bottom of the punch head 201, a slide rail 202 is fixedly arranged. By starting the upper press 2, the punch head 201, the slide rail 202 and the reinforced support slide plate 203 are driven to move downward. Start the electric push rod 210 to drive the reinforced support slide plate 203 to slide on the slide rail 202 for position adjustment. The bottom of the slide rail 202 is slidably connected with the reinforced support slide plate 203. At the bottom of the reinforced support slide plate 203, a cushion plate 204 is fixedly arranged. The forging is flattened by the continuous downward displacement of the reinforced support slide plate 203. A number of springs 205 are distributed at the bottom of the cushion plate 204, and at the bottom of each spring 205, a pressure plate 206 is fixedly arranged. The pressure plate 206 is in contact with the workpiece under force and compresses the spring 205, which first plays a leveling function when forging the workpiece. In the middle of the cushion plate 204, a reinforced central material supporting ejector rod 207 is inserted. A number of electromagnets 208 are distributed on the outside of the reinforced central material supporting ejector rod 207, and each electromagnet 208 is fixed on the cushion plate 204. The reinforced central material supporting ejector rod 207 adsorbs the waste after punching, and the pressure plate 206 drives the waste adsorbed on the reinforced central material supporting ejector rod 207 to be pushed out through the elasticity of the spring 205 itself. On one side of the punch head 201, an electric push rod 210 is installed by bolts. The output end of the electric push rod 210 extends to one side of the reinforced support slide plate 203 and is detachably connected with the reinforced support slide plate 203 by bolts.

[0036] Below the reinforced central material supporting ejector rod 207, there is a punching cylinder 3. A tray 301 is sleeved outside the punching cylinder 3. At the bottom of the support box body 101, there is a lower press 307. At the output end of the lower press 307, there is a punch 308. A connecting seat 209 is inserted at the bottom of the punching cylinder 3. The punch 308 passes through the connecting seat 209 and the punching cylinder 3 and extends to the top of the punching cylinder 3. A number of air cylinders 302 are distributed on the outside of the tray 301, and each air cylinder 302 is installed on the top of the connecting seat 209 through a column. The output ends of the multiple air cylinders 302 are all fixedly provided with ejector rods 303, and at one end of each ejector rod 303, a reinforced L-shaped pull plate 304 is threadedly connected. The reinforced L-shaped pull plate 304 is located on the upper surface of the tray 301. A limiting arc groove 305 is opened at the bottom of the reinforced L-shaped pull plate 304. The cross-sectional shape of the limiting arc groove 305 is arc-shaped. At the bottom of the connecting seat 209, a reinforced support frame 306 is installed by bolts. The reinforced support frame 306 is located at the bottom of the inner cavity of the forging chamber 102. The reinforced support frame 306 is detachably connected with the support box body 101 by bolts.

[0037] When in use according to the above structure, the staff installs the device at a designated position. When forging and manufacturing a workpiece, the workpiece is placed on the top of the punching cylinder 3. The tray 301 first positions the workpiece. The air cylinder 302 is started to drive the ejector rod 303 to drive the reinforced L-shaped pull plate 304 to displace. The reinforced L-shaped pull plate 304 abuts against the outside of the workpiece and causes the workpiece to be lifted by the traction force of the displacement of the reinforced L-shaped pull plate 304, so that the bottom of the reinforced L-shaped pull plate 304 can extend to the bottom of the workpiece, ensuring the stability of the workpiece during forging and leaving a certain gap between the workpiece and the punching cylinder 3. And it fits with the bottom of the workpiece through the limit arc groove 305, preventing the workpiece from shifting when being pressed simultaneously from the bottom and the top.

[0038] Then the upper press 2 is started to drive the punch head 201, the slide rail 202 and the reinforced support slide plate 203 to displace downward. The electric push rod 210 is started to drive the reinforced support slide plate 203 to slide on the slide rail 202 for position adjustment, so that the pressure plate 206 and the reinforced central supporting ejector rod 207 can be located at the top of the workpiece. The reinforced support slide plate 203 continues to displace downward to flatten the forging, and the pressure plate 206 is stressed and abuts against the workpiece, causing the spring 205 to compress, which first plays a leveling function when forging the workpiece, enabling the workpiece to be placed horizontally and preventing poor forming quality of the workpiece.

[0039] The lower press 307 drives the punch 308 to displace upward and penetrate through the connecting seat 209 and the punching cylinder 3 to punch the workpiece. After punching, it retracts to avoid overheating of the punch 308 due to too long staying time. During punching, the reinforced central supporting ejector rod 207 adsorbs the waste after punching, and the pressure plate 206 drives the waste adsorbed on the reinforced central supporting ejector rod 207 to be ejected through the elasticity of the spring 205 itself.

[0040] Different from the prior art, the present application discloses a new ring forging blank hydraulic press. The electric push rod 210 drives the reinforced support sliding plate 203 to slide on the slide rail 202 for position adjustment, so that the pressure plate 206 and the reinforced central blank holding ejector rod 207 can be located at the top of the workpiece, which is conducive to the continuous downward displacement of the reinforced support sliding plate 203 to flatten the forging. When the pressure plate 206 is stressed and abuts against the workpiece, the spring 205 is compressed, which first plays a leveling function when forging the workpiece, enabling the workpiece to be placed horizontally and avoiding poor forming quality of the workpiece. The bottom of the reinforced L-shaped pull plate 304 can extend to the bottom of the workpiece, ensuring the stability of the workpiece during forging and leaving a certain gap between the workpiece and the punching cylinder 3. And it fits with the bottom of the workpiece through the limit arc groove 305, preventing the workpiece from shifting when pressed simultaneously from the bottom and the top. After punching, the punch 308 retracts to avoid overheating of the punch 308 due to too long residence time. During punching, the reinforced central blank holding ejector rod 207 adsorbs the waste after punching, and the pressure plate 206 drives the waste adsorbed on the reinforced central blank holding ejector rod 207 to be ejected through the elasticity of the spring 205 itself, which is conducive to the continuous operation of the device.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
