DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figures 1 to 9 , which is the first embodiment of the present invention, and provides a forging device for flange production, which can achieve the automatic material spreading effect of the forging device for flange production, and includes a hammer mechanism 100, on which auxiliary mechanisms 200 are respectively provided, and the auxiliary mechanisms 200 are connected to a positioning mechanism 400 through a movable mechanism 300, and the hammer mechanism 100 includes a base 101, a pad 102 installed on the base 101, and a forging hammer 103 fixedly connected to the pad 102 through the base 101; Among them, the setting of the hammer mechanism 100 can effectively forge the workpiece, the setting of the auxiliary mechanism 200 can ensure the material spreading on the workpiece, and can better carry out the forging process and ensure the forging effect. The setting of the movable mechanism 300 can effectively drive the auxiliary mechanism 200 and the positioning mechanism 400 to operate, and the setting of the positioning mechanism 400 can limit the workpiece and ensure that the workpiece is located in the relative center area of ​​the hammer mechanism 100 during use. The setting of the pad 102 can better protect the base 101 and place the workpiece above it. The forging hammer 103 can forge the workpiece.

[0030] Reference Figures 4 to 6 The auxiliary mechanism 200 includes an air release sheet 201 installed inside the base 101, a material storage box 202 is fixedly connected inside the base 101, a material spreading nozzle 203 is provided at the bottom of the material storage box 202, and an air inlet 204 is provided on one side of the material storage box 202 close to the movable mechanism 300.

[0031] Furthermore, the provision of the air release sheet 201 can ensure that when the air pressure inside the accommodating chamber 301 in the base 101 rises suddenly, the air release sheet 201 can effectively discharge the air inside it, the provision of the spreading nozzle 203 can spread material on the workpiece located on the pad 102, and sprinkling borax onto the workpiece can improve the forging quality of the workpiece, and the provision of the air inlet 204 can introduce the air located inside the accommodating chamber 301 into the storage box 202. When the air inside the storage box 202 increases, the internal pressure increases, causing the spreading nozzle 203 at the bottom of the storage box 202 to exhaust air, and the spreading nozzle 203 will sprinkle part of the material during the exhaust process, thereby achieving the purpose of spreading material, and the provision of this device can effectively sprinkle borax onto the workpiece.

[0032] Reference Figure 1 to Figure 6 A circular groove 205 is provided on the outer wall of the storage box 202, and a resistance plate 206 is rotatably connected inside the circular groove 205. The resistance plate 206 is provided with a connecting hole 207 corresponding to the air inlet hole 204. The resistance plate 206 is located in the circular groove 205 and is fixedly connected with a swivel 208. A plurality of teeth 209 are arranged in a ring array inside the swivel 208. A plurality of resistance claws 210 are provided inside the circular groove 205 corresponding to the teeth 209. A positioning rod 211 is provided between the resistance claws 210 and the circular groove 205. The plurality of resistance claws 210 are connected to a reset cover 213 via a reset plate 212, and the reset cover 213 is connected to the circular groove 205 via a torsion spring 214.

[0033] Reference Figure 2 to Figure 8The circular groove 205 is set to limit the rotating ring 208 inside it. The rotating ring 208 is made of metal. The setting of the rotating ring 208 can effectively limit the contact plate 206. When the contact plate 206 rotates, it will drive the rotating ring 208 to rotate. When the rotating ring 208 rotates, it will be limited by the interfering claw 210, so that it can only rotate in one direction, which can better drive the connecting hole 207 on the contact plate 206 to rotate. The setting of the teeth 209 can rotate with the rotating ring 208. At the same time, when the teeth 209 are limited, the rotating ring 208 will also be limited. The setting of the interfering claw 210 can effectively limit the teeth 209, and the positioning rod 211 can effectively block the interfering claw 210, so that the interfering claw 210 can only move in one direction.

[0034] The deflation sheet 201 includes a round sheet 201a, a plurality of barrier ropes 201b are arranged inside the round sheet 201a, a round hole 201c is arranged at the center of the round sheet 201a, and the round sheet 201a is made of rubber. Furthermore, the setting of the barrier rope 201b can effectively limit the deformation degree of the disc 201a. When the connecting hole 207 and the air inlet hole 204 are in an interlaced state, the air inside the accommodating chamber 301 is discharged from the inside of the connecting hole 207. The instantaneous discharge speed is relatively large, which simultaneously drives the two barrier ropes 201b on the disc 201a to deform and complete the exhaust work. When the connecting hole 207 and the air inlet hole 204 are in a connected state, the barrier rope 201b can effectively prevent the disc 201a from producing excessive deformation under the same pressure state inside the accommodating chamber 301, so that the storage box 202 can obtain part of the pressure, which is convenient for better discharging the material from the spreading nozzle 203.

[0035] Reference Figure 2 to Figure 6 The material spreading nozzle 203 includes a bottom pipe 203a fixedly connected to the material storage box 202, a blocking net 203b is arranged inside the bottom pipe 203a, an inclined pipe 203c is fixedly connected to the bottom of the bottom pipe 203a, a rubber cover 203e is sleeved at the end of the inclined pipe 203c through an end ring 203d, and a material leakage hole 203f is opened at the center of the rubber cover 203e. The connecting hole 207 is adapted to the air inlet 204, and the ends of the connecting hole 207 and the air inlet 204 are both provided with a rubber ring to prevent air leakage, and the cross-sections of the connecting hole 207 and the air inlet 204 are both circular.

[0036] Reference Figure 2 to Figure 6The setting of the bottom tube 203a can effectively limit the material inside it, the setting of the barrier net can retain part of the material to prevent the material from suddenly and instantly passing through the end ring 203d, the setting of the inclined tube 203c can change the spraying angle of the end ring 203d, and can better spread the material on the workpiece, and the setting of the rubber cover 203e can effectively limit the material to prevent the material from naturally spilling during use. When the discharge hole 203f is impacted by the air pressure from the inside of the storage box 202, the instantaneous air flow rate in the discharge hole 203f increases, thereby driving the rubber cover 203e to deform, causing the discharge hole 203f to suddenly increase, and then spilling the material. The spilled material enters the top of the workpiece, which can better forge the workpiece.

[0037] The cross section of the abutment plate 206 is circular, the abutment plate 206 is matched with the movable mechanism 300 , and the rotating ring 208 is rotatably connected with the circular groove 205 .

[0038] In summary, the setting of the rubber cover 203e can effectively limit the material to prevent it from naturally spilling during use. The setting of the barrier rope 201b can effectively limit the deformation degree of the disc 201a. The setting of the teeth 209 can rotate with the swivel 208. At the same time, when the teeth 209 are limited, the swivel 208 will also be limited. The setting of the resisting claws 210 can effectively limit the teeth 209.

[0039] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention. The difference from the previous embodiment is the movable mechanism 300. This embodiment provides a transmission mechanism for a forging device for flange production, which can effectively drive the auxiliary mechanism 200 and the positioning mechanism 400 to operate. The movable mechanism 300 includes a receiving chamber 301 opened inside the base 101, and grooves 302 are opened at both ends of the receiving chamber 301. An external rod 303 is slidably connected inside the groove 302. The external rod 303 is located above the forging hammer 103 and is connected to a sleeve ring 304. The external rod 303 is located inside the receiving chamber 301 and is fixedly connected to a counterweight arc plate 305. An avoidance groove 306 is opened at the bottom of the counterweight arc plate 305.

[0040] Among them, the setting of the positioning mechanism 400 can effectively limit the workpiece, the setting of the groove body 302 can effectively limit the external rod 303, the setting of the sleeve ring 304 can effectively receive the force from the forging hammer 103, and the setting of the counterweight arc plate 305 can better impact the extrusion plate 408, thereby driving the positioning mechanism 400 to move the workpiece, and can better adjust the position of the workpiece.

[0041] The movable mechanism 300 further includes a movable groove 307 formed on the accommodating cavity 301 . A lifting plate 308 is disposed inside the movable groove 307 . The lifting plate 308 is provided with a lifting groove 309 corresponding to the abutting plate 206 .

[0042] Furthermore, the setting of the movable groove 307 can effectively limit the lifting plate 308, the setting of the resistance plate 206 can drive the lifting groove 309 to rise and fall, and the setting of the lifting groove 309 can effectively drive the resistance plate 206 to twist.

[0043] The rest of the structure is the same as that of Example 1.

[0044] In summary, during use, the device utilizes the power of the forging hammer 103 when it rises to drive the counterweight arc plate 305 to rise, and then utilizes the counterweight arc plate 305 to apply force to the positioning mechanism 400 to achieve the purpose of fine-tuning the workpiece. The setting of the positioning mechanism 400 can effectively limit the workpiece, and the setting of the groove body 302 can effectively limit the external rod 303.

[0045] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention, and is different from the previous embodiment in that the positioning mechanism 400. This embodiment provides a positioning mechanism 400 for a forging device for flange production, which solves the problem that when the workpiece moves toward the inside of the base 101 during the forging device for flange production, it is difficult for the staff to move the workpiece back. The positioning mechanism 400 includes a positioning bar 401 located on the pad 102, a reset arc plate 402 is slidably connected to the positioning bar 401, a reset seat 403 is fixedly connected to the base 101, a top groove 404 is provided inside the reset seat 403, a plurality of spring grooves 405 are provided at the bottom of the top groove 404, a connecting groove 406 is commonly connected to the bottom of the plurality of spring grooves 405, and an extension groove 407 is provided at the other end of the connecting groove 406.

[0046] Among them, the setting of the pad 102 can effectively limit the workpiece on its top, the setting of the positioning bar 401 can effectively limit the reset arc plate 402 on its top, the setting of the reset seat 403 can effectively limit the components inside it, the setting of the top groove 404 can better limit the extrusion plate 408, the setting of the spring groove 405 can accommodate the reset spring 410 inside it, and at the same time limit the piston rod 409 inside it, the connecting groove 406 is fixedly connected to the reset spring 410, the setting of the connecting groove 406 can connect multiple spring grooves 405 at the same time, and the setting of the extension groove 407 can effectively limit the slide rod 411.

[0047] Reference Figure 6 to Figure 9The positioning mechanism 400 further includes a squeeze plate 408 slidably connected to the inside of the top groove 404, the squeeze plate 408 is adapted to the inner wall of the avoidance groove 306, a plurality of piston rods 409 are fixedly connected to the bottom of the squeeze plate 408, the bottom of the piston rod 409 is connected to the connecting groove 406 through a reset spring 410, a slide bar 411 is slidably connected to the inside of the extension groove 407, one end of the slide bar 411 is connected to the connecting groove 406 through a reset rope 412, and the other end of the slide bar 411 is fixedly connected to a push frame 413. The top of the positioning bar 401 is arranged in an inclined shape, and its top gradually rises outward from the center of the pad 102, and the cross section of the connecting groove 406 is arc-shaped.

[0048] Furthermore, hydraulic oil is provided inside the spring groove 405 and the connecting groove 406. The cross-section of the extrusion plate 408 is circular. The setting of the extrusion plate 408 can drive multiple piston rods 409 to move together at the same time. The setting of the piston rod 409 can squeeze the oil inside the spring groove 405 downward, thereby driving the slide bar 411 to move. During the movement of the slide bar 411, the push rack 413 can be driven to move. After the push rack 413 moves, the workpiece located on one side of the push rack 413 can be driven to move.

[0049] The rest of the structure is the same as that of Example 2.

[0050] During operation, the workpiece is placed between the reset arc plate 402 and the push frame 413, and the forging hammer 103 is started for one stroke. The forging hammer 103 is initially at a distance twice the thickness of the workpiece from the pad 102, which is convenient for better adjustment of the position of the workpiece, and the push frame 413 is reserved for pushing the workpiece, which is also convenient for the staff to adjust the position of the workpiece; When the forging hammer 103 moves upward, the forging hammer 103 moves upward, driving the sleeve ring 304 to rise, the sleeve ring 304 rises and drives the external rod 303 to rise, the external rod 303 rises and drives the counterweight arc plate 305 to rise, the counterweight arc plate 305 squeezes the air inside the accommodating chamber 301 when it rises, and the air inside the accommodating chamber 301 is discharged through the groove body 302 at this time, when the top of the counterweight arc plate 305 exceeds the groove body 302, the air inside it is discharged through the air release sheet 201, and when the counterweight arc plate 305 contacts the lifting plate 308, it drives the lifting plate 308 upward. The lifting plate 308 rises, driving the lifting slot 309 to contact the edge of the resistance plate 206, thereby driving the resistance plate 206 to rotate. During the rotation of the resistance plate 206, the rotating ring 208 and the teeth 209 are driven to rotate. When the rotating ring 208 and the teeth 209 are pressed against the resistance teeth 209, the resistance teeth 209 are driven to twist the reset plate 212 and deform slightly. When the teeth 209 pass the resistance teeth 209, the resistance teeth 209 are reset under the action of the reset plate 212 and the torsion spring. When the forging hammer 103 descends, the counterweight arc plate 305 loses its supporting force and follows the forging hammer 103 to descend. Due to the need for hammering by the forging hammer 103, the descending speed is greater than the counterweight arc plate 305. When the counterweight arc plate 305 descends, it contacts the extrusion plate 408. During the descending process, the extrusion plate 408 can simultaneously drive multiple piston rods 409 to descend together. At this time, the return spring 410 contracts and deforms to accumulate elastic potential energy. The piston rod 409 squeezes the oil inside the spring groove 405 downward, thereby driving the slide bar 411 to move. During the movement of the slide bar 411, the push frame 413 can be driven to move, and the reset rope 412 can be driven to stretch and accumulate elastic potential energy. After the push frame 413 moves, it can drive the workpiece located on one side of the push frame 413 to move. When the counterweight arc plate 305 is reset, the reset spring 410 drives the piston rod 409 to reset, and the reset rope 412 drives the slide bar 411 to reset.

[0051] When the connecting hole 207 and the air inlet hole 204 are in an interlaced state, the air inside the accommodating chamber 301 is discharged from the connecting hole 207, and its instantaneous discharge speed is relatively large, which simultaneously drives the two barrier ropes 201b on the disc 201a to deform, completing the exhaust work. When the connecting hole 207 and the air inlet hole 204 are connected under the multiple lifting of the forging hammer 103, the barrier rope 201b can effectively prevent the disc 201a from producing excessive deformation under the same pressure state inside the accommodating chamber 301, so that the storage box 202 can obtain part of the pressure, which is convenient for better discharging the material from the spreading nozzle 203.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
