[0002] In the field of metal forging, the removal of iron oxide slag from the workpiece surface during the forging process remains a core issue limiting production efficiency and product quality. Existing technologies, such as the die steel forging device with slag cleaning function (CN119772081A) disclosed by Suzhou Biyat Die Steel Co., Ltd., remove slag using a cleaning assembly driven by an internal transmission mechanism within a power hammer. However, this process is out of sync with the forging cycle, requiring frequent machine downtime. The forging equipment with a cleaning function (CN119870352A) developed by Liyang Jinkun Forging Co., Ltd. utilizes a vacuum head for auxiliary cleaning, but is inefficient at removing adherent slag and fails to address the issue of mold damage caused by residual slag on the forging table. Furthermore, while the forging debris cleaning mechanism (CN222133330U) developed by Qingdao Yuyu Machinery collects slag using a lifting block and a swinging cleaning rod, the cleaning process requires manual triggering, making automated continuous production impossible.

[0022] The application will be described in detail in combination with the drawings in the embodiments of the application.

[0023] A forging equipment comprises a mounting frame 101, a hydraulic cylinder 102 fixedly connected to the mounting frame 101, a hammer head 103 fixedly connected to the moving end of the hydraulic cylinder 102, a rotating rod 201 rotatably connected to the lower end of the mounting frame 101, a supporting rod 203 fixedly connected to the lower part of the rotating rod 201, a cleaning brush 204 fixedly connected to the end of the supporting rod 203, a sliding groove 202 formed in the rotating rod 201, the upper part of the sliding groove 202 being helical and the lower part of the sliding groove 202 being linear, a connecting plate 104 slidably connected to the rotating rod 201, one end of the connecting plate 104 being fixedly connected to the moving end of the hydraulic cylinder 102, a groove for cooperating with the rotating rod 201 being formed in the connecting plate 104, a sliding block being arranged in the groove and slidably connected to the sliding groove 202, and a forging table 301 arranged below the hammer head 103.

[0024] Referring to Figures 1-3 ,

[0025] In use of the forging equipment, first, the worker places the red-hot workpiece on the forging table 301, then drives the hammer head 103 to move downward by controlling the moving end of the hydraulic cylinder 102 to extend, so that the hammer head 103 cooperates with the forging table 301 to achieve the beating effect on the workpiece, thereby realizing the forging function.

[0026] In the process of forging the workpiece, since the workpiece is repeatedly beaten, the iron slag on the surface of the workpiece falls off immediately when the workpiece is beaten, and the cost of the fallen iron slag is mainly iron oxide. After the iron slag falls off, it stays on the surface of the forging table 301. When the forging table 301 bears pressure, it will vibrate. The iron slag accumulated on the forging table 301 is easy to produce dust and fly everywhere under the action of pressure and vibration, and the iron slag adheres to the surface of the forging table 301 under the action of pressure, which affects the beating of the workpiece and interferes with the normal operation of the worker. Therefore, the normal equipment needs the worker to manually clean the iron slag with cleaning tools, which affects the processing progress, wastes time and manpower, needs to be stopped for processing, and increases the processing cost.

[0027] In use of the forging equipment, first, the worker places the red-hot workpiece on the forging table 301, then drives the hammer head 103 to move downward by controlling the moving end of the hydraulic cylinder 102 to extend, so that the hammer head 103 cooperates with the forging table 301 to achieve the beating effect on the workpiece, thereby realizing the forging function.

[0028] Since the connecting plate 104 is provided with a groove for sliding cooperation with the rotating rod 201, and the groove is provided with a sliding block slidingly connected in the sliding groove 202, when the connecting plate 104 moves upward, the sliding block slides upward along the sliding groove 202, and the rotating rod 201 rotates on the mounting frame 101, the supporting rod 203 rotates driven by the rotating rod 201, and the cleaning brush 204 sweeps the surface of the forging table 301, thereby realizing the function of automatically cleaning the iron slag accumulated on the surface of the forging table 301, without the need for the worker to manually clean with tools, saving time.

[0029] When the forging table 301 is cleaned, the moving end of the hydraulic cylinder 102 is extended to reset, and the slider cooperates with the sliding groove 202 to automatically reset the rotating rod 201. The rotating rod 201 drives the cleaning brush 204 to automatically reset, realizing the function of secondary cleaning and resetting. At this time, the worker places the workpiece on the forging table 301 again, and the hammer head 103 continues to beat the workpiece. Since the upper part of the sliding groove 202 is spiral-shaped and the lower part is linear, when the hammer head 103 moves downward, the slider slides linearly downward in the lower part of the sliding groove 202, realizing the function of limiting the rotating rod 201.

[0030] Through the above structure, the function of automatically cleaning iron slag during forging of the workpiece can be realized, the overall process is simple, there is no complex operation, manual intervention is not required, a separate power source is not required, and the production efficiency is improved.

[0031] The up-and-down movement of the hydraulic cylinder 102 is converted into the rotary movement of the rotating rod 201 through the sliding connection of the connecting plate 104 and the rotating rod 201. When the hammer head 103 is pressed down, the connecting plate 104 moves downward along the linear segment of the sliding groove 202 of the rotating rod 201, and at this time the rotating rod 201 remains stationary. When the hammer head 103 moves upward to reset, the slider moves upward along the spiral segment of the sliding groove 202, driving the rotating rod 201 to rotate the supporting rod 203 and the cleaning brush 204 to clean the surface of the forging table 301. This design seamlessly connects the forging process and the cleaning action, and uses the original power of the hydraulic system to realize automatic cleaning with zero additional energy consumption.

[0032] The sliding groove 202 is designed in combination of the upper spiral shape and the lower linear shape, forming the dual functions of mechanical limiting and power conversion. The lower linear segment ensures that the rotating rod 201 is stably positioned when the hammer head 103 is pressed down, avoiding that the cleaning brush 204 touches the forging table 301 by mistake. The upper spiral segment converts the vertical movement into the rotary torque of the rotating rod 201 through the spiral movement of the slider, driving the cleaning brush 204 to complete the covering cleaning. This structure makes the cleaning brush 204 complete the secondary cleaning simultaneously in the reset stage, ensuring that there is no residual iron slag.

[0033] The cleaning brush 204 is rigidly connected to the rotating rod 201 through the supporting rod 203, forming a rotatable broom structure. When the cleaning brush 204 rotates with the rotating rod 201, the bristles generate dynamic contact pressure with the surface of the forging table 301, and the iron slag is thrown away from the contact surface through centrifugal force. The cleaned iron slag naturally falls under the action of gravity, avoiding secondary dust pollution. The cooperation of the slider and the spiral sliding groove 202 has a self-locking feature. When the hydraulic cylinder 102 completes the reset action, the rotating rod 201 automatically returns to the initial position, ensuring that the cleaning brush 204 is always in standby position. This mechanical reset mechanism has higher environmental adaptability than the electric control mechanism, and can withstand high temperature and vibration working conditions in the forging workshop.

[0034] The device realizes seamless connection of the forging and cleaning cycle by the following design, the workpiece is flipped, and the cleaning program is triggered synchronously to avoid downtime; the rotation speed of the cleaning brush 204 is matched with the reset speed of the hydraulic cylinder 102, ensuring that the cleaning cycle is synchronized with the forging rhythm; the vertical movement trajectories of the hammer head 103 and the cleaning brush 204 do not interfere with each other, realizing function reuse in a compact space.

[0035] The forging table 301 is rotatably connected with a collection box 302.

[0036] Referring to Figure 3 ,

[0037] The collection box 302 is used to collect the iron slag that falls off. Since the forging table 301 is a conical table, when the workpiece is hit by the hammer, part of the iron slag can automatically slide down along the taper surface of the forging table 301, thereby being collected in the collection box 302. When the forging table 301 needs to be cleaned, the cleaning brush 204 sweeps the surface of the forging table 301, and the accumulated iron slag automatically falls into the collection box 302.

[0038] The bottom of the collection box 302 is provided with a plurality of leakage holes 303, and the forging table 301 is fixedly connected with a plurality of push pieces 304.

[0039] Referring to Figures 5-6 ,

[0040] While the forging table 301 is being cleaned, the collection box 302 is controlled to rotate reciprocally, so that the iron slag in the collection box 302 can be discharged through the plurality of leakage holes 303, realizing the function of automatic discharge. Since the plurality of push pieces 304 are fixed, when the collection box 302 rotates reciprocally, the plurality of push pieces 304 can push the iron slag, promote the iron slag to be discharged through the plurality of leakage holes 303, and at the same time, the iron slag in pieces is broken under the action of the push pieces 304 and the leakage holes 303, facilitating subsequent recycling.

[0041] The collection box 302 forms a centrifugal field by reciprocating rotation, so that the iron slag migrates to the direction of the leakage holes 303 under the dual action of centrifugal force and gravity. When the collection box 302 completes 2-3 times of forward and reverse rotation per second, the iron slag continuously impacts the edge of the leakage holes 303 under the action of inertia, and cooperates with the fixed pushing of the push pieces 304, which can effectively prevent the iron slag from clogging the leakage holes.

[0042] The lower end of the collection box 302 is fixedly connected with a crushing cylinder 501, the crushing cylinder 501 is cylindrical, the inner wall of the crushing cylinder 501 is a frosted surface, and the lower end of the forging table 301 is fixedly connected with a crushing cone 502.

[0043] Referring to Figure 3 ,

[0044] When the collecting box 302 generates reciprocating rotation to drive the crushing cylinder 501 to rotate, and when the iron slag is discharged through the plurality of leakage holes 303, the iron slag enters the space formed by the crushing cylinder 501 and the crushing cone 502, and since the inner wall of the crushing cylinder 501 is a frosted surface, the crushing cylinder 501 and the crushing cone 502 can cooperate to crush the iron slag, so that the iron slag is discharged through the gap between the crushing cylinder 501 and the crushing cone 502, and the recovery requirement is met.

[0045] The frosted surface of the inner wall of the crushing cylinder 501 and the conical surface of the crushing cone 502 form a dynamic crushing cavity. When the collecting box 302 rotates, the iron slag enters the crushing cavity under the action of centrifugal force and undergoes three-stage crushing. In the first stage, the iron slag is torn into 20-50 mm particles under the action of shear force in the gap between the frosted surface and the conical surface. In the second stage, the gap is dynamically reduced to 5-8 mm by the crushing cone 502 pressing downward, and the particles are extruded to generate internal cracks. In the third stage, the gap is further reduced to 2-3 mm, and the final particle size of the iron slag is ≤3 mm, meeting the steel plant's standard for recycling.

[0046] The crushing cone 502 is fixedly connected with a plurality of crushing ribs 503 on the surface.

[0047] Referring to Figure 3 ,

[0048] The plurality of crushing ribs 503 help to crush the iron slag, and cooperate with the frosted surface of the crushing cylinder 501 to further refine the iron slag.

[0049] An included angle gradually decreasing from top to bottom is arranged between the crushing cone 502 and the crushing cylinder 501.

[0050] Referring to Figure 3 ,

[0051] The crushing cone 502 and the crushing cylinder 501 cooperate to crush the iron slag, and the iron slag automatically moves downward under the action of gravity, and when the iron slag is discharged, the iron slag above automatically moves downward, and as the included angle between the crushing cone 502 and the crushing cylinder 501 gradually decreases, the degree of refinement of the crushed slag is greater, so that the iron slag is gradually refined.

[0052] The inner wall of the crushing cylinder 501 is provided with a plurality of sand particles with a particle size of 3-5 cm.

[0053] Referring to Figure 3 ,

[0054] The sand particles are fixed on the inner wall of the crushing cylinder 501 by mortar, and are used to further refine the iron slag in cooperation with the plurality of crushing ribs 503. The iron slag in pieces collides with the sand particles under the action of centrifugal force, which helps the subsequent continuous crushing process.

[0055] The lower end of the rotating rod 201 is fixedly connected with a gear 401, and the upper end of the collecting box 302 is fixedly connected with a tooth ring 402.

[0056] Referring to Figure 5 ,

[0057] When the rotating rod 201 rotates, the gear 401 rotates, the tooth ring 402 rotates, and the collecting box 302 rotates, so that the collecting box 302 is not controlled alone, and the surplus power generated by the hydraulic cylinder 102 as a single driving source can be used to save energy and simplify the operation.

[0058] The distance between the lower end of the plurality of pushers 304 and the bottom surface of the collecting box 302 is 2 mm.

[0059] Referring to Figure 6 ,

[0060] The distance between the plurality of pushers 304 and the bottom surface of the collecting box 302 can avoid direct contact between the pushers 304 and the bottom surface of the collecting box 302 to generate wear, and can ensure that the shearing force generated by the cooperation between the pushers 304 and the leakage holes 303 can break the large piece-shaped iron oxide.

[0061] The cleaning brush 204 is made of steel wire.

[0062] Referring to Figure 8 ,

[0063] The cleaning brush 204 made of steel wire has good wear resistance and high temperature resistance, and is suitable for cleaning the forging table 301.
