Description

Technical Field

[0001] The invention relates to the field of bearing ring production, and in particular to a high-speed and low-loss bearing ring blanking device. Background Art

[0002] In the structure of bearings, there are generally outer rings and inner rings, collectively referred to as bearing rings. Bearing rings are generally cut by cold cutting steel pipes with blades. For cold cutting, the blade width is greater than 1.5mm, and the material loss is greater than 15%. The groove of the bearing ring needs to be turned and formed, and the material loss increases by about 10%, resulting in a relatively large material loss of more than 25%. In addition, the cold cutting speed is slow, which can reach 2-3s / pcs, the production efficiency is relatively low, and the cost is high. Therefore, a new cutting method is needed to solve the above technical problems. Summary of the invention

[0003] The present invention provides a high-speed and low-loss bearing ring blanking device, which can realize high-speed and low-loss blanking, with a cutting loss of less than 5%, greatly reducing the production cost, and a very fast cutting speed of 2-3pcs / s, thereby improving production efficiency and greatly reducing costs.

[0004] To achieve the above object, the present invention provides the following technical solution: a high-speed and low-loss bearing ring blanking device, comprising:

[0005] A driving motor for providing power;

[0006] A material discharge component, wherein three main shafts are arranged in a triangular position inside the material discharge component, and a material discharge screw is arranged on the main shaft. From one end to the other end of the material discharge screw, the height of the thread on the material discharge screw gradually increases, and the thread top width of the thread gradually decreases, and a material discharge channel for the pipe material to pass through is formed between the three main shafts.

[0007] Before feeding, the pipe material needs to be heated. Before the pipe material enters the feeding channel, it has been preheated. The surface of the pipe material can be squeezed and deformed by the screw teeth on the three main shafts. As the pipe material continues to move in the feeding channel, the screw teeth cut deeper and deeper into the surface of the pipe material until the pipe material is cut off to achieve feeding;

[0008] Since the thread is slowly squeezed on the surface of the tube to form a groove and finally cut off naturally, the end face of the cut bearing ring is relatively smooth, there is no need to retain the remaining material from processing, and the precision is also very high, and the tube is not easy to deform.

[0009] A transmission mechanism is used to connect the output shaft of the driving motor and the three main shafts to make the three main shafts rotate synchronously.

[0010] Preferably, the transmission mechanism comprises a sun gear connected to the output shaft of the driving motor, and three planetary gears arranged around the sun gear, and a planetary shaft connected to one side of the planetary gear is connected to the corresponding main shaft through a coupling.

[0011] In addition, the unloading assembly includes a front side plate and a rear side plate arranged side by side, a plurality of guide pillars are passed between the front side plate and the rear side plate, the unloading screw is located between the front side plate and the rear side plate, and the main shaft passes through the rear side plate, and a feed hole corresponding to the unloading channel is provided in the middle of the rear side plate. The pipe material enters the unloading channel through the feed hole and can directly contact the unloading screw for cutting.

[0012] The front and rear side panels can be disassembled for easy maintenance and to keep a safe distance between the outside world and the unloading screw.

[0013] Preferably, the height of the screw thread gradually decreases from the front side plate to the rear side plate, and the crest width of the screw thread gradually increases from the front side plate to the rear side plate.

[0014] Preferably, the end of the screw thread has the largest height, and a radial cross section is provided at the end of the screw thread, so that the last connected part can be directly cut off at the end to ensure that the end face of the cut bearing ring is flat.

[0015] Preferably, a transmission is provided between the driving motor and its output shaft, so as to adjust the output to a suitable rotation speed.

[0016] Preferably, a cooling water channel is provided inside the blanking screw, and cooling water is passed into the cooling water channel, so that the blanking screw can be continuously cooled to ensure that the blanking screw can continue to work.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The surface of the tube can be extruded and cut through the screw teeth on the three main shafts. As the tube moves continuously in the feeding channel, the screw teeth cut deeper and deeper into the surface of the tube until the tube is cut off. Since the screw teeth slowly extrude the surface of the tube to form grooves and finally cut off naturally, high-speed and low-loss feeding can be achieved. The cutting loss is less than 5%, which greatly reduces the production cost. The cutting speed is very fast, which can reach 2-3pcs / s, which improves the production efficiency, greatly reduces the cost, and the tube is not easy to deform. Moreover, the shape of the product being fed can be adjusted by changing the shape of the screw teeth, and the pitch between the screw teeth can also correspond to different products, reducing the processing of the post-process.

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the present invention provides a high-speed and low-loss bearing ring blanking device, comprising:

[0025] A driving motor 1, used to provide power;

[0026] A material discharge component 3, wherein three main shafts 8 are arranged in a triangular position inside the material discharge component 3, and a material discharge screw 34 is arranged on the main shaft 8. From one end to the other end of the material discharge screw 34, the height b of the thread 35 thereon gradually increases, and the crest width a of the thread 35 gradually decreases, and a material discharge channel for the pipe material 4 to pass through is formed between the three main shafts 8.

[0027] Before unloading, the pipe material 4 needs to be heated. Before the pipe material 4 enters the unloading channel, it has been preheated. A heating device is set during the conveying process of the pipe material 4. The surface of the pipe material 4 can be extruded and cut through the screw teeth 35 on the three main shafts 8. As the pipe material 4 continues to move in the unloading channel, the screw teeth 35 cut the surface of the pipe material 4 deeper and deeper until the pipe material 4 is cut off to achieve unloading;

[0028] Since the screw thread 35 slowly squeezes the surface of the tube material 4 to form a groove and is finally cut off naturally, the end face of the cut bearing ring is relatively flat, there is no need to retain the processing surplus, and the accuracy is also very high, and the tube material 4 is not easy to deform.

[0029] Since the screw thread 35 continuously squeezes various positions of the outer surface of the tube material 4, the material feeding is uninterrupted and the efficiency of the material feeding is very high.

[0030] In order to be able to correspond to bearing rings with different requirements, such as bearing inner rings and bearing outer rings, which have different shapes and sizes, this can be achieved by using a feeding screw 34 with different pitches. The thread 35 on the feeding screw 34 can also adopt different widths and shapes to meet the structural requirements of the bearing ring (such as the end face of the bearing ring is concave or convex or flat).

[0031] A transmission mechanism 7 is used to connect the output shaft 6 of the driving motor 1 and the three main shafts 8 so that the three main shafts 8 rotate synchronously.

[0032] The transmission mechanism 7 includes a sun gear connected to the output shaft 6 of the driving motor 1, and three planetary gears arranged around the sun gear. The planetary shaft connected to one side of the planetary gear is connected to the corresponding main shaft 8 through a coupling 2. The sun gear can drive the planetary gear to move synchronously, and the transmission is stable and reliable.

[0033] In practical applications, a protective cover can be provided on the outside of the transmission mechanism for protection.

[0034] As an embodiment of the blanking component 3, Figure 3 As shown, the unloading assembly 3 includes a front side plate 32 and a rear side plate 33 arranged side by side, a plurality of guide pillars 31 are passed between the front side plate 32 and the rear side plate 33, the unloading screw 34 is located between the front side plate 32 and the rear side plate 33, and the main shaft 8 passes through the rear side plate 33, and a feed hole corresponding to the unloading channel is provided in the middle of the rear side plate 33, and the pipe material 4 enters the unloading channel through the feed hole and can directly contact the unloading screw 34 for cutting.

[0035] The front side plate 32 and the rear side plate 33 can be disassembled for easy maintenance, and a safe distance is maintained between the outside world and the unloading screw 34 .

[0036] The height b of the screw thread 35 gradually decreases from the front side plate 32 to the rear side plate 33 , and the crest width a of the screw thread 35 gradually increases from the front side plate 32 to the rear side plate 33 .

[0037] The height b of the end of the screw thread 35 is the largest, and a radial cross section 36 is provided at the end of the screw thread 35, so that the last connected part can be directly cut off at the end to ensure that the end surface of the cut bearing ring is flat.

[0038] A transmission 5 is provided between the driving motor 1 and its output shaft 6, and can adjust the output to a suitable rotation speed.

[0039] The interior of the unloading screw 34 is provided with a cooling water channel, and cooling water is introduced into the cooling water channel, so as to continuously cool the unloading screw 34 and ensure that the unloading screw 34 can continue to work.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
