Technical Field

[0002] In order to improve material plasticity, reduce material waste, optimize production processes, improve product quality, reduce grinding allowances, and control heat treatment deformation, before the bearing ring is forged, it is necessary to use a hot shearing device to cut the bearing ring raw material to control its size and wall thickness, thereby improving the efficiency of subsequent bearing ring hole expansion. However, after cutting the bearing ring raw material, most existing hot shearing devices need to let it stand to dissipate heat. Obviously, a lot of time is wasted during the standing process of the bearing ring raw material, which leads to a decrease in the efficiency of the hot shearing work and a major defect. For this reason, we propose a blanking mechanism for hot shearing of bearing ring forging. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

A blanking sleeve 12 which is communicated with the blanking cavity 11 is fixedly installed at the outer end of the hot shear seat 1, a spiral auger plate 14 is rotatably installed in the blanking cavity 11 and the blanking sleeve 12, and a heat dissipation pipe 13 is fixedly installed on the inner wall of the blanking sleeve 12, a driving motor 15 is fixedly installed at the outer end of the hot shear seat 1, and the output shaft of the driving motor 15 is connected to the spiral auger plate 14 and the rotating rod 2, and a threaded rod 25 which is threadedly connected to the hot shears 22 is rotatably installed in the rotating rod 2. A hydraulic push rod 17 which is fixedly connected to the upper end of the outer periphery of the blanking sleeve 12 is provided on the front side of the hot shear seat 1, and a push plate 18 is fixedly installed on the outer end of the hydraulic push rod 17 through its output shaft.

[0025] Working principle: When in use, the bearing ring raw material is placed on the upper side of the hot shear seat 1, and the end of the bearing ring is in contact with the push plate 18, and the hydraulic push rod 17 is started. The hydraulic push rod 17 pushes the bearing ring raw material to move through its output shaft, so that the front end of the bearing ring raw material is in contact with the baffle 21, and the drive motor 15 is started. The drive motor 15 drives the hot shears 22 and the spiral auger plate 14 to rotate through its output shaft. The rotating hot shears 22 can perform hot shearing on the bearing ring raw material, and the bearing ring raw material that falls off by hot shearing will fall into the blanking cavity 11. The rotating spiral auger plate 14 can guide the bearing ring raw material to the front end of the blanking sleeve 12, thereby facilitating the recovery of the bearing ring raw material after hot shearing;

[0026] Among them, the heat dissipation pipe 13 can be connected to the external coolant storage device at both ends. Through the internal infusion pump of the external coolant storage device, the coolant can be circulated between the external coolant storage device and the heat dissipation pipe 13. When the coolant enters the heat dissipation pipe 13, the bearing ring raw material moving inside the blanking sleeve 12 can be cooled.

[0027] As a further description of the above technical solution: a first gear 16 fixedly connected to the rotating shaft of the spiral auger plate 14 and a second gear 26 fixedly connected to the rotating shaft of the rotating rod 2 are provided on the outer side of the hot shear seat 1. The first gear 16 and the second gear 26 are meshed with each other, the output shaft of the drive motor 15 is fixedly connected to the middle part of the first gear 16, the middle part of the baffle 21 is fixedly connected to the rotating rod 2, and a movable sleeve 23 is fixedly installed at the rotation center of the hot shears 22. The movable sleeve 23 is sleeved on the outer periphery of the rotating rod 2, and a threaded sleeve 24 inserted into the inner cavity of the rotating rod 2 is fixedly installed in the movable sleeve 23, and the threaded rod 25 is rotatably connected to the threaded sleeve 24.

[0028] Specifically, through the mutually meshing first gear 16 and second gear 26, when the output shaft of the driving motor 15 rotates, the hot shears 22 and the spiral auger plate 14 can be driven to rotate at the same time;

[0029] When the hot shear size needs to be adjusted according to the specifications of the bearing ring, the threaded rod 25 can be rotated at the front end of the rotating rod 2. The rotating rod 2 is connected to the threaded sleeve 24 through the plug-in connection, which restricts the movement direction of the threaded sleeve 24. The rotating threaded rod 25 can drive the threaded sleeve 24 to move through the threaded connection between it and the threaded sleeve 24, so that the distance between the hot shears 22 and the baffle 21 can be adjusted, thereby achieving the effect of adjusting the hot shear size.

[0030] As a further description of the above technical solution: two limit rotating seats 3 are fixedly installed on the upper end of the hot shear seat 1, and the two limit rotating seats 3 are arranged on the front side of the hot shears 22. A rotating plate 31 is rotatably installed in the limit rotating seat 3, and an insertion cavity 32 is opened in the middle of the limit rotating seat 3 and the rotating plate 31. A plurality of positioning blocks 33 are slidably installed between the limit rotating seat 3 and the rotating plate 31, and adjacent positioning blocks 33 fit together. A second limit slider 35 and a first limit slider 34 are fixedly installed at the front and rear ends of each positioning block 33, respectively. The front end of the limit rotating seat 3 is opened with a The first limiting slide block 34 is slidably connected to the first limiting slide groove 341, and the rear end of the rotating plate 31 is provided with a second limiting slide groove 351 slidably connected to the second limiting slide block 35. Two symmetrically arranged positioning blocks 361 are fixedly installed on the front end surface of the limiting rotating seat 3, and an arc-shaped limiting slide rod 36 is fixedly installed between the two limiting rotating seats 3. A movable block 362 slidably connected to the limiting slide rod 36 is fixedly installed at the rear end of the rotating plate 31, and a spring 363 is fixedly installed between the movable block 362 and the positioning block 361 and is sleeved on the outer periphery of the limiting slide rod 36.

[0031] Specifically, when installing the bearing ring material, the rotating plate 31 is rotated at the front end of the limited rotating seat 3. The limited rotating seat 3 is connected to the first limiting slide 34 and the first limiting groove 341 through the sliding connection between the first limiting slide 34, which restricts the movement direction of each positioning block 33. The rotating rotating plate 31 can be connected to the second limiting groove 351 and the second limiting slide 35 through the sliding connection between the second limiting groove 351 and the second limiting slide 35, thereby driving each positioning block 33 to expand outward to the periphery of the insertion cavity 32.

[0032] Through the plug-in connection between the bearing ring raw material and the inserting cavity 32, the bearing ring raw material can be plugged and installed into the two limited rotating seats 3, and the end of the bearing ring raw material is in contact with the push plate 18;

[0033] By loosening the rotating plate 31, the spring 363 can restore the deformation and drive the rotating plate 31 to rotate in the opposite direction, thereby driving each positioning block 33 to shrink inward until it fits with the outer periphery of the bearing ring raw material. The bearing ring raw material can be limited in the limiting rotating seat 3, and the bearing ring raw material can be prevented from being offset during the hot shearing process, thereby ensuring the stability of the hot shearing.
