Description

Technical Field

[0001] This utility model belongs to the field of forging technology, and in particular relates to a flange forging device. Background Technology

[0002] Flanges are mechanical components used to connect pipes, valves, pumps, and other equipment. They are commonly used in industrial and construction fields. They are usually round or rectangular and have pre-designed holes for fixing bolts, which can connect two pipes or equipment together. Flange forging equipment is a mechanical device specifically used to manufacture flanges. It uses a forging process to process metal blanks into flanges of the required shape and size.

[0003] In existing flange forging devices, after the flange is forged in the mold, the mold needs to be manually separated in order to remove the flange. At this time, the mold may be in a high temperature state, which may cause danger to the workers when separating the mold. If the two molds can be automatically separated when the hydraulic rod is lifted after stamping, these problems can be effectively avoided. Therefore, we propose a flange forging device. Utility Model Content

[0004] The purpose of this utility model is to provide a flange forging device. By pushing the gripper with the driven rod, the gripper causes the first connecting block to squeeze the spring. Then, the spring resets the gripper, allowing the driven rod to move the gripper upward. This solves the problem of automatically separating the two dies after stamping.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a flange forging device, including a support frame and a housing fixedly connected inside the support frame. The top of the support frame is provided with a separation mechanism, and the inner wall of the housing is provided with a clamping mechanism. The separation mechanism includes a hydraulic press fixedly connected to the top of the support frame. A hydraulic rod is fixedly connected to the output end of the hydraulic press. A connecting strip is fixedly connected to the outer surface of the hydraulic rod. Two driven rods are fixedly connected to the bottom of the connecting strip. A first mold is provided on the top of the housing. Connecting shells are fixedly connected to both sides of the first mold. Two grippers are provided inside the connecting shells. First connecting blocks are fixedly connected to both sides of the two grippers. Fixed rods are slidably connected to the inner walls of the first connecting blocks. Both ends of the fixed rods are fixedly connected to the inner walls of the connecting shells. A spring is fixedly connected between the outer surface of the first connecting block and the inner wall of the connecting shell. The inner side of the spring is sleeved on the outer surface of the fixed rod.

[0006] Furthermore, each of the two grippers is fixedly connected to a toggle plate at its bottom, and a first limiting rod is slidably connected to the inner wall of the toggle plate, with both ends of the first limiting rod being fixedly connected to the inner wall of the connecting shell.

[0007] Furthermore, a second mold is provided at the bottom of the first mold, and four first insert rods are fixedly connected to the bottom of the first mold. The second mold has first insertion holes that match the outer surfaces of the four first insert rods.

[0008] Furthermore, the clamping mechanism includes a first connecting plate fixedly connected to the inner wall of the housing. The top of the first connecting plate contacts the bottom of the second mold. A support rod is fixedly connected to the bottom of the first connecting plate. The support rod is disposed inside the housing. The bottom of the support rod is fixedly connected to the inner wall of the housing. A movable cylinder is slidably connected to the outer surface of the support rod. Four connecting rods are rotatably connected to the inner wall of the movable cylinder. One end of each of the four connecting rods is rotatably connected to a clamping plate. A protrusion is fixedly connected to one side of the clamping plate. The outer surface of the protrusion is inserted into the inner wall of the second mold.

[0009] Furthermore, a second connecting plate is fixedly connected to one side of the movable cylinder. One end of the second connecting plate penetrates the inner wall of the housing. Positioning blocks are fixedly connected to both sides of the second connecting plate. A sliding groove matching the outer surface of the positioning block is opened inside the housing. A second insert rod is inserted into the inner wall of the positioning block. A plurality of second insertion holes matching the outer surface of the second insert rod are opened inside the sliding groove.

[0010] Furthermore, four extension plates are fixedly connected to the outer surface of the movable cylinder, and electric push rods are fixedly connected to the top of each of the four extension plates. The top of each electric push rod is fixedly connected to the bottom of the first connecting plate.

[0011] Furthermore, a second connecting block is fixedly connected to both sides of the clamping plate, and a second limiting rod is slidably connected to the inner wall of the second connecting block, with both ends of the second limiting rod being fixedly connected to the inner wall of the first connecting plate.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a driven rod that pushes the grippers, causing them to move in opposite directions. The grippers then slide the first connecting block on the fixed rod, which in turn compresses the spring. When the driven rod fully enters the connecting shell, the spring resets and pushes the first connecting block back to its original position, causing the grippers to reset. After stamping, the hydraulic rod moves upward, and the driven rod also moves upward. This driven rod, which can move the entire connecting shell upward, achieves the effect of automatically separating the two molds after stamping.

[0013] 2. This utility model, by setting up clamping plates, can activate four electric actuators. At this time, the four electric actuators will pull the extension plate upward, thereby causing the extension plate to drive the moving cylinder to move upward along the support rod. Then the moving cylinder will push the connecting rod, thereby enabling the connecting rod to push the clamping plates. At this time, the four clamping plates will move away from each other. Simultaneously, the clamping plates will drive the second connecting block to slide on the second limiting rod. By driving the protrusion to be clamped in the second mold, the clamping plate can achieve the effect of clamping and fixing molds of different specifications.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] Please see Figure 1-8 As shown, this utility model is a flange forging device, including a support frame 101 and a housing 102 fixedly connected inside the support frame 101. The top of the support frame 101 is provided with a separation mechanism 2, and the inner wall of the housing 102 is provided with a clamping mechanism 3. This device can automatically separate two molds through the separation mechanism 2, and then adjust the device itself through the clamping mechanism 3 to clamp and fix molds of different specifications. The separation mechanism 2 includes a hydraulic press 201 fixedly connected to the top of the support frame 101. A hydraulic rod 202 is fixedly connected to the output end of the hydraulic press 201. A connecting strip 203 is fixedly connected to the outer surface of the hydraulic rod 202. Two driven rods 204 are fixedly connected to the bottom of the connecting strip 203. The hydraulic press 201 can be started. At this time, the hydraulic press 201 will press the hydraulic rod 202 downward. At the same time, the hydraulic rod 202 will also drive the connecting strip 203 to move downward. A first mold 205 is provided on the top of the housing 102. A connecting shell 206 is fixedly connected to both sides of the first mold 205. Two grippers 207 are provided inside the connecting shell 206. A first connecting block 208 is fixedly connected to both sides of the two grippers 207. When the grippers 207 move, they will drive the first connecting block 208 to move. At this time, the first connecting block 208 has a stabilizing effect. Simultaneously, the movement of the first connecting block 208 can also enable the next step of transmission. Fixed rods 209 are slidably connected to the inner wall of the first connecting block 208. Both ends of the fixed rods 209 are fixedly connected to the inner wall of the connecting shell 206. A spring 210 is fixedly connected between the outer surface of the first connecting block 208 and the inner wall of the connecting shell 206. The inner side of the spring 210 is sleeved on the outer surface of the fixed rod 209. The fixed rods 209 restrict the movement of the spring 210, so that the spring 210 will not tilt or deviate when it moves, ensuring that the device can transmit normally.

[0020] Both grippers 207 have actuating plates 211 fixedly connected to their bottoms. The inner walls of the actuating plates 211 are slidably connected to first limiting rods 212. Both ends of the first limiting rods 212 are fixedly connected to the inner walls of the connecting shell 206, which can move the actuating plates 211. At this time, the actuating plates 211 will drive the grippers 207 to move. At the same time, the first limiting rods 212 play a stabilizing role in the movement of the actuating plates 211.

[0021] The bottom of the first mold 205 is provided with a second mold 213. Four first insert rods 214 are fixedly connected to the bottom of the first mold 205. The interior of the second mold 213 is provided with first insertion holes 215 that match the outer surface of the four first insert rods 214.

[0022] The clamping mechanism 3 includes a first connecting plate 301 fixedly connected to the inner wall of the housing 102. The top of the first connecting plate 301 contacts the bottom of the second mold 213. A support rod 302 is fixedly connected to the bottom of the first connecting plate 301. The support rod 302 is located inside the housing 102 and supports the first connecting plate 301 to prevent it from collapsing due to pressure, thus ensuring that the device can perform molding normally. The bottom of the support rod 302 is fixedly connected to the inner wall of the housing 102, and a movable cylinder 303 is slidably connected to the outer surface of the support rod 302. Four connecting rods 304 are rotatably connected to the inner wall of the movable cylinder 303. The movable cylinder 303 can slide along the support rod 302. At this time, the movable cylinder 303 will drive the connecting rods 304 to move, thereby enabling the device to proceed to the next transmission step. One end of each of the four connecting rods 304 is rotatably connected to a clamping plate 305. A protrusion 306 is fixedly connected to one side of the clamping plate 305. The outer surface of the protrusion 306 is inserted into the inner wall of the second mold 213. The connecting rods 304 will drive the clamping plate 305 to move. At this time, the clamping plate 305 will drive the protrusion 306 to move, inserting the protrusion 306 into the second mold 213 and fixing the second mold 213.

[0023] A second connecting plate 307 is fixedly connected to one side of the movable cylinder 303. One end of the second connecting plate 307 penetrates the inner wall of the housing 102. Positioning blocks 308 are fixedly connected to both sides of the second connecting plate 307. The movable cylinder 303 will drive the second connecting plate 307 to move together. Then the second connecting plate 307 will drive the positioning blocks 308 to move. The movable cylinder 303 can then be fixed by fixing the positioning blocks 308. The housing 102 has a sliding groove 309 that matches the outer surface of the positioning block 308. The inner wall of the positioning block 308 is respectively inserted with a second insert rod 311. The sliding groove 309 has several second insertion holes 310 that match the outer surface of the second insert rod 311. The second insert rod 311 can be inserted into the positioning block 308 and the second insertion holes 310 to fix the position of the positioning block 308. At this time, the positioning block 308 will fix the movable cylinder 303 through the second connecting plate 307.

[0024] Four extension plates 312 are fixedly connected to the outer surface of the movable cylinder 303. Each of the four extension plates 312 is fixedly connected to the top of an electric push rod 313. The top of the electric push rod 313 is fixedly connected to the bottom of the first connecting plate 301. The electric push rod 313 will pull the extension plate 312. At this time, the extension plate 312 will pull the movable cylinder 303, so that the device can perform normal transmission.

[0025] The clamping plate 305 is fixedly connected to both sides of the second connecting block 314. The inner wall of the second connecting block 314 is slidably connected to the second limiting rod 315. Both ends of the second limiting rod 315 are fixedly connected to the inner wall of the first connecting plate 301. When the clamping plate 305 moves, it will drive the second connecting block 314 to slide along the second limiting rod 315. At this time, the second connecting block 314 plays a stabilizing role in the movement of the clamping plate 305.

[0026] One specific application of this embodiment is: When the staff needs to use the equipment, they first place the material to be stamped and forged into the first mold 205, and then start the hydraulic press 201. At this time, the hydraulic press 201 will cause the hydraulic rod 202 to move downward. Then the hydraulic rod 202 will drive the driven rod 204 to move downward through the connecting bar 203. When the hydraulic rod 202 stamps the material in the first mold 205, the driven rod 204 will also enter the connecting shell 206. At this time, the driven rod 204 will push the jaws 207, causing the two jaws 207 to move in opposite directions. At this time, the jaws 207 will drive the first connecting block 208 to slide on the fixed rod 209. Then the first connecting block 208 will press the spring 210. When the driven rod 204 is fully inserted into the connecting shell 206, the spring 210 will reset and push the first connecting block 208, thereby causing the first connecting block 208 to drive the gripper 207 to reset. After the stamping is completed, the hydraulic rod 202 will move upward. At this time, the driven rod 204 will also move upward. Then the driven rod 204 will drive the connecting shell 206 to move upward as a whole through the gripper 207, thereby causing the connecting shell 206 to drive the first mold 205 to move upward. At this time, the first mold 205 will drive the first insert rod 214 to slide in the second mold 213, thereby separating the first mold 205 from the second mold 213, achieving the effect of automatically separating the two molds after stamping. When it is necessary to replace the second mold 213 and the first mold 205, the four electric actuators 313 can be activated. At this time, the four electric actuators 313 will pull the extension plate 312 upward, so that the extension plate 312 drives the moving cylinder 303 to move upward along the support rod 302. Then the moving cylinder 303 will push the connecting rod 304, so that the connecting rod 304 can push the clamping plate 305. At this time, the four clamping plates 305 will move away from each other. At the same time, the clamping plates 305 will drive the second connecting block 314 to slide on the second limit rod 315, so that the clamping plates 305 drive the protrusion 306 to disengage from the second mold 213. At this time, the second mold 213 and the first mold 205 can be replaced, achieving the effect of clamping and fixing molds of different specifications. After the replacement is completed, the electric push rod 313 can be restarted to push the extension plate 312 downward, thereby re-clamping the second mold 213. During the movement of the moving cylinder 303, the moving cylinder 303 will also drive the second connecting plate 307 to move, thereby causing the second connecting plate 307 to drive the positioning block 308 to slide in the slide groove 309. After clamping is completed, the second insert rod 311 can be inserted into the second insert hole 310 and the positioning block 308 to fix the position of the moving cylinder 303.
