Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for producing grinding balls, and particularly relates to a linear buffer mechanism of a steel ball shaping disk suitable for a steel ball shaping device. Background Art

[0002] For example, the steel ball shaping device disclosed in the authorization announcement number CN 208758919 U includes a fixed disk shaft and a rotating disk shaft. The fixed disk shaft is provided with a fixed disk, and the fixed disk is provided with a steel ball outlet. The rotating disk shaft is provided with a rotating disk, and the rotating disk corresponds to the fixed disk; a fixed shaping ring and a rotating shaping ring are provided between the rotating disk and the fixed disk. The fixed shaping ring is fixed to the right side of the fixed disk, and a fixed shaping ring steel ball rolling groove is formed on the right side of the fixed shaping ring around the circumferential direction of the fixed shaping ring. The groove is recessed in the right side of the fixed shaping ring. A steel ball introduction cavity for to-be-shaped and a shaping steel ball outlet cavity are formed on the circumferential surface of the fixed shaping ring. The steel ball introduction cavity for to-be-shaped and the shaping steel ball outlet cavity are separated by a cavity partition. The steel ball introduction cavity to be shaped is communicated with the steel ball rolling groove of the fixed shaping ring. The right side of the shaping steel ball outlet cavity is constituted as a shaping steel ball introduction port and the shaping steel ball introduction port is communicated with the fixed shaping ring steel ball rolling groove, and the left side of the shaping steel ball outlet cavity is constituted as a shaping steel ball outlet and the shaping steel ball outlet is communicated with the steel ball outlet. The rotating shaping ring is fixed to the left side of the turntable and has a rotating shaping ring steel ball rolling groove recessed in the left side of the rotating shaping ring around the circumferential direction of the rotating shaping ring. The rotating shaping ring steel ball rolling groove corresponds to the fixed shaping ring steel ball rolling groove, and the right end of the turntable shaft is connected to the power transmission mechanism.

[0003] The steel ball to be shaped is introduced into the cavity, which introduces the steel ball to be shaped, which is still in a high-temperature state and rolled in the previous process, between the fixed shaping ring steel ball rolling groove and the rotary shaping ring steel ball rolling groove. In the process of the power transmission mechanism driving the turntable shaft, the turntable shaft drives the turntable, and the turntable drives the rotary shaping ring to rotate, the steel ball to be shaped is shaped and the steel ball that has completed the shaping is led out of the shaping steel ball outlet cavity to the steel ball outlet.

[0004] A shaping ring buffer mechanism is provided at the right end of the fixed disc shaft and between the right side of the fixed disc shaft right support seat and the left side of the fixed disc. The shaping ring buffer mechanism includes a buffer spring and a buffer spring support ring. The buffer spring is placed on the right end of the fixed disc shaft with the buffer spring support ring at a position corresponding to the right side of the fixed disc shaft right support seat and the left side of the fixed disc, wherein: the buffer spring is located on the right side of the buffer spring support ring, the left end of the buffer spring abuts on the right side of the buffer spring support ring, and the right end of the buffer spring abuts on the left side of the fixed disc, and the left side of the buffer spring support ring contacts the right side of the fixed disc shaft right support seat and the right side of the fixed disc shaft right support seat cover. When encountering a steel ball to be shaped with poor outer roundness, that is, when the dimensional deviation of the steel ball to be shaped is serious, the fixed shaping ring and the rotating shaping ring are subjected to a large axial force, which is buffered and reduced by the buffer spring to avoid excessive wear of the fixed shaping ring and the rotating shaping ring and prevent the motor (power transmission mechanism) from locking (stifling) and being damaged.

[0005] Although the purpose of buffering and vibration reduction can be achieved by tightening the buffer spring, its reliability is not strong in actual use. On the one hand, the force applied to the buffer spring is not so linear, and on the other hand, the buffer spring is prone to fatigue failure. When the buffer spring is fatigued, the free length of the buffer spring (the length when subjected to external force) will gradually shorten, resulting in the fixed shaping ring being unable to effectively reset to the side of the rotating shaping ring, and the distance between the rotating shaping ring steel ball rolling groove and the fixed shaping ring steel ball rolling groove increases, affecting the shaping effect of the steel ball to be shaped; in severe cases, it will cause equipment disability. Utility Model Content

[0006] In order to solve the above problems, the purpose of the utility model is to provide a linear buffer mechanism of a steel ball shaping disk suitable for a steel ball shaping device, which effectively realizes linear buffering and vibration reduction of the shaping disk.

[0007] In order to achieve the above technical purpose, the technical solution of the utility model is:

[0008] The steel ball shaping disk linear buffer mechanism includes a first shaping disk and a second shaping disk. The second shaping disk and the first shaping disk are arranged opposite to each other. A steel ball shaping cavity is provided between the second shaping disk and the first shaping disk. The first shaping disk is provided with a first hydraulic cylinder. The hydraulic oil in the first hydraulic cylinder is communicated with the hydraulic oil in the second hydraulic cylinder through a hydraulic oil pipe. The second hydraulic cylinder is provided with a counterweight block. The counterweight block allows the hydraulic oil in the second hydraulic cylinder to be input into the first hydraulic cylinder through the hydraulic oil pipe. The first hydraulic cylinder pushes the first shaping disk close to the second shaping disk.

[0009] The first shaping disk is provided with a first shaping disk shaft, and the first shaping disk slides back and forth along the first shaping disk shaft; the second shaping disk is provided with a second shaping disk shaft, and the second shaping disk rotates around the second shaping disk shaft as the axis; the first hydraulic cylinder pushes the first shaping disk along the first shaping disk shaft to approach the second shaping disk.

[0010] Because the steel balls to be shaped, rolled in the previous process, are elliptical in shape, they roll and shape within the steel ball shaping chamber. The first or second shaping discs need to give way axially to prevent excessive wear of the steel ball shaping chamber and prevent the motor from locking. When the first shaping disc is subjected to an axial force, it shifts along its axis. The hydraulic oil in the first hydraulic cylinder flows into the second hydraulic cylinder, which pushes the counterweight to achieve axial gain of the first shaping disc. When the first shaping disc is freed from the axial force, the counterweight causes the hydraulic oil in the second hydraulic cylinder to flow into the first hydraulic cylinder. The first hydraulic cylinder pushes the first shaping disc toward the second shaping disc, resetting it.

[0011] The second shaping disk is connected to a pulley, which is connected to a motor via a belt, and the motor drives the second shaping disk to rotate around the second shaping disk axis.

[0012] A first shaping ring and a second shaping ring are arranged between the first shaping disk and the second shaping disk, the second shaping ring is arranged on the second shaping disk, and the second shaping ring rotates with the second shaping disk, the first shaping ring is arranged on the first shaping disk, and between the first shaping ring and the second shaping ring, the first shaping ring is provided with a first shaping ring steel ball rolling groove, the first shaping ring steel ball rolling groove is arranged around the circumferential direction of the first shaping ring, the first shaping ring is provided with a steel ball inlet to be shaped and a shaping steel ball outlet communicating with the first shaping ring steel ball rolling groove, the steel ball inlet to be shaped and the shaping steel ball outlet are separated by a cavity partition; between the first shaping ring and the second shaping ring, the second shaping ring steel ball rolling groove is provided, and the second shaping ring steel ball rolling groove and the first shaping ring steel ball rolling groove constitute a steel ball shaping cavity.

[0013] The first shaping disk is provided with a steel ball outlet, and the shaping steel ball outlet is communicated with the steel ball outlet.

[0014] During the processing, the steel balls to be shaped, which are still in a high-temperature state and rolled in the previous process, are introduced into the steel ball shaping chamber through the steel ball inlet. The motor drives the second shaping disk to rotate around the second shaping disk axis to shape the steel balls to be shaped. The shaped steel balls are led out through the shaping steel ball outlet and the steel ball outlet.

[0015] The first shaping disc shaft and the second shaping disc shaft are composed of the same core shaft. The first shaping disc and the second shaping disc are both mounted on the core shaft. The first shaping disc slides back and forth along the core shaft, and the second shaping disc rotates on the core shaft. The first hydraulic cylinder pushes the first shaping disc along the core shaft to approach the second shaping disc. Since the second shaping disc and the first shaping disc are both mounted on the core shaft, the coaxiality of the two in the axial direction can be ensured, thereby reducing the eccentricity caused by installation errors or long-term use. It can also make the relative position between the first shaping disc and the second shaping disc more stable, reducing the risk of eccentricity caused by vibration or other external forces. This can also avoid deformation of the shaping cavity due to eccentricity, which affects the roundness and shaping accuracy of the steel ball.

[0016] The first shaping disc is provided with a pushing disc sleeve, and the first hydraulic cylinder pushes the first shaping disc through the pushing disc sleeve.

[0017] The cylinder diameter of the second hydraulic cylinder is smaller than that of the first hydraulic cylinder. The cylinder diameter of the second hydraulic cylinder is smaller than that of the first hydraulic cylinder, which can reduce the mass of the counterweight.

[0018] The second hydraulic cylinder is arranged at the bottom of the counterweight block, and the counterweight block is provided with a guide frame. The second hydraulic cylinder pushes the counterweight block to move along the guide frame.

[0019] The first hydraulic cylinder and / or the second hydraulic cylinder includes a cylinder body, a hydraulic oil chamber is provided in the cylinder body, a piston is provided in the hydraulic oil chamber, and a piston is provided in the piston. The piston seals the hydraulic oil in the hydraulic oil chamber, and the cylinder body is provided with a hydraulic oil port connected to the hydraulic oil chamber, and the hydraulic oil pipe is connected to the hydraulic oil port.

[0020] This utility model uses two hydraulic cylinders with interconnected hydraulic oil to ensure that the counterweight can always apply pressure to the first shaping disk, achieving linear cushioning and vibration reduction of the shaping disk, improving the shaping effect of the steel balls, and solving the problem of spring fatigue failure. At the same time, by utilizing hydraulic cylinders with different cylinder diameters, this utility model can also reduce the mass of the counterweight, reducing the size and weight of the equipment.

The second shaping ring 42 is fixedly arranged on the second shaping disc 32. The first shaping ring 41 is fixedly arranged on the first shaping disc 31.

[0030] Between the first shaping ring 41 and the second shaping ring 42, the first shaping ring 41 is provided with a first shaping ring steel ball rolling groove 81, and the first shaping ring steel ball rolling groove 81 is arranged around the circumferential direction of the first shaping ring 41.

[0031] Between the first shaping ring 41 and the second shaping ring 43, the second shaping ring 42 is provided with a second shaping ring steel ball rolling groove 86, and the second shaping ring steel ball rolling groove 86 is arranged opposite to the first shaping ring steel ball rolling groove 81, and the second shaping ring steel ball rolling groove 86 and the first shaping ring steel ball rolling groove 81 constitute a steel ball shaping cavity for the shaping steel ball.

[0032] The first shaping disc 31 is provided with a steel ball outlet 85 , which is communicated with the shaping steel ball outlet 83 to enable the steel ball to be separated from the steel ball shaping cavity.

[0033] The second shaping disk 32 is rotatably connected to the core shaft 2. A pulley 71 is provided on the second shaping disk 32. The pulley 71 is connected to the rotating shaft of the motor through a belt. The motor drives the pulley 71 through the belt. The pulley 71 drives the second shaping disk 32 to rotate around the core shaft 2. The second shaping ring 42 rotates synchronously with the second shaping disk 32.

[0034] In order to limit the second shaping disk 32 and prevent the second shaping disk 32 from deviating toward the right core shaft support seat 12 due to axial force, the core shaft 2 is provided with a second shaping disk limiting ring 92, and the left end of the second shaping disk limiting ring 92 abuts against the second shaping disk 32.

[0035] The first shaping disk 31 slides back and forth on the core shaft 2, and the first shaping ring 41 moves synchronously with the first shaping disk 31.

The second hydraulic cylinder 52 is located at the bottom of the counterweight block 55, and the piston rod of the second hydraulic cylinder 52 pushes the counterweight block 55 to move in the vertical guide frame 54.

[0038] Since the steel balls to be shaped rolled in the previous process are introduced into the steel ball shaping chamber through the steel ball inlet 82 to be shaped, the motor 73 drives the second shaping ring 42 to rotate, and the steel balls are separated from the steel ball shaping chamber through the shaping steel ball outlet 83, thereby realizing the shaping of the steel balls. During the steel ball shaping process, when the first shaping ring 41 is subjected to axial force, the first shaping ring 41 is displaced to the left core shaft support seat 11 side, the first shaping plate 31 pushes the push plate sleeve 5, and the push plate sleeve 5 pushes the piston rod of the first hydraulic cylinder 51, and the hydraulic oil in the first hydraulic cylinder 51 is transported to the second hydraulic cylinder 52 through the hydraulic oil pipe 53.
