Description

Technical Field

[0001] This utility model relates to the field of forging equipment technology, specifically to a high-efficiency cutting mechanism for bearing forging machines. Background Technology

[0002] The outer ring of large bearings is usually produced by forging, which includes initial forging of the outer ring material and punching.

[0003] In punching, a forging machine is usually used to squeeze the punch into the material. The platform of the forging machine used to support the punching of the material also has openings for auxiliary scrap and punches to fall one by one. In the existing technology, a forging handling robot is usually used to grab the punch from below the platform and place it on the next material waiting to be punched.

[0004] However, in actual production, it was found that because the punch remains in contact with the surface of the waste material when it falls, the waste material is prone to thermal adhesion to the punch, making it difficult for the robot to push the waste material under the punch laterally, and causing the punch to easily deform due to torque. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a high-efficiency cutting mechanism for bearing forging machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency cutting mechanism for a bearing forging machine, comprising a frame and a punch, a punching table for placing materials is fixedly installed on the frame, a turning groove for accommodating falling punches and waste materials is provided below the punching table, a waste pusher with a polygonal cross-section is provided on the frame, and a pushing component for reciprocatingly guiding the waste pusher past the position where the punch falls, and a transmission assembly for guiding the waste pusher to rotate around its axis is provided between the frame and the waste pusher.

[0007] The present invention is further configured such that the diameter of the circumscribed circle of the polygon is less than or equal to the height of the waste material.

[0008] The present invention is further configured to include a raised area opened between the frame and the punching table for connecting the turning groove and the outside of the frame, the raised area being able to accommodate waste material and punches passing through.

[0009] The present invention is further configured such that: the punching platform includes a support plate detachably connected above the tilting groove, which is used to adjust the diameter and height of the opening on the punching platform for communicating with the tilting groove; when the punch and the waste are in a coaxial position, the upper end of the punch is inside the opening.

[0010] The present invention is further configured such that the cross-section of the flipping groove is trapezoidal.

[0011] The present invention is further configured such that: the transmission assembly includes two sets of meshing gears and racks, the gears are fixedly mounted at both ends of the waste pusher, and the racks are fixedly mounted on the frame.

[0012] The present invention is further configured such that a splash guard covering the gears and rack is fixedly installed on the frame.

[0013] The present invention is further configured such that a guide strip for guiding the sliding of waste material is fixedly provided on the frame.

[0014] In summary, this utility model has the following beneficial effects: Under the action of the pushing member, the waste pusher rotates due to the action of the transmission assembly, causing several edges on its surface to continuously push the punch to jump in the vertical direction, thereby effectively reducing the lateral force applied to the punch during the process of the waste pusher pushing the waste away from the punch.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The high-efficiency cutting mechanism of the bearing forging machine, such as Figures 1 to 3 As shown, the machine includes a frame 1 and a punch 5. A punching table 3 and a primary forging table 2 for placing materials are fixedly installed on the frame 1. The frame 1 can slide along the slide rail so that the primary forging table 2 and the punching table 3 are alternately positioned under the forging hammer of the forging machine. The punching table 3 includes a support plate that can be detachably connected to the main structure of the punching table 3 above, and a tilting groove 31 below for accommodating the falling punch 5 and scrap. The replacement of the support plate is used to adjust the diameter and height of the opening on the punching table 3 for connecting the tilting groove 31. When punches 5 of different diameters and scrap are in a coaxial position, the upper end of the punch 5 is in the opening, and the side end of the punch 5 is attached to the inner wall of the opening. After the scrap moves away from the punch 5, the punch 5 leaves the opening and is completely in the tilting groove 31.

[0023] In order to effectively reduce the lateral compressive force applied to the punch 5 due to adhesion and friction when the waste material is separated from the punch 5, the frame 1 is provided with a waste pusher 6 with a polygonal cross-section, and a pusher 7 that reciprocates to guide the waste pusher 6 past the position where the punch 5 falls. A transmission assembly that guides the waste pusher 6 to rotate around its axis is provided between the frame 1 and the waste pusher 6.

[0024] Under the action of the pusher 7, when the pusher 6 passes the position where the punch 5 falls for the first time, it will guide the waste away from the punch 5. During this process, the pusher 6 rotates due to the action of the transmission component, causing several edges on its surface to continuously push the punch 5 to jump in the vertical direction, thereby effectively reducing the lateral force applied to the punch 5 during the process of the pusher 6 pushing the waste away from the punch 5. The opening stabilizes the jumping path of the punch 5 during this process. At the same time, in order to make it easier for the pusher 6 to separate the punch 5 from the waste, it slides to the bottom of the punch 5. The circumscribed circle diameter of the polygon is less than or equal to the height of the waste. In this application, the circumscribed circle diameter of the polygon is equal to the height of the waste.

[0025] like Figure 3 as well as Figure 4 As shown, it also includes a raised area 4 opened between the frame 1 and the punching table 3 to connect the tilting groove 31 and the outside of the frame 1. The raised area 4 can accommodate waste material and punch 5 passing through. When the waste pusher 6 passes the position where the punch 5 falls for the second time, the waste material has been pushed away from below the punch 5 by the waste pusher 6. The frame 1 is fixedly provided with a guide bar 12 to guide the waste material to slide. At this time, the waste pusher 6 gradually guides the punch 5 to tilt. During this process, the punch 5 tilts onto the waste pusher 6. With the help of the mechanical claw, the tilted punch 5 can quickly leave the raised area 4 with the assistance of the waste pusher 6. In order to prevent the punch 5 from rolling away from the position of the mechanical claw during the tilting process, the cross section of the tilting groove 31 is trapezoidal, and the punch 5 can slide down along the inner wall assembly of the tilting groove 31.

[0026] like Figure 5 As shown, the transmission assembly includes two sets of meshing gears 8 and racks 9. The gears 8 are fixedly mounted at both ends of the push rod 6, and the racks 9 are fixedly mounted on the frame 1. A splash guard 11 covering the gears 8 and racks 9 is fixedly mounted on the frame 1.
