Description

Technical Field

[0001] This utility model relates to the field of forging equipment technology, specifically to an auxiliary forging device for a bearing forging machine. 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 this process, initial forging refers to the step of having a punch that needs to penetrate the material first placed on a smooth-bottomed processing table, where a forging machine forces part of the punch into the material, in order to reduce the amount of material on the material that is taken away by the punch during punching.

[0004] During processing, it was found that when the punch is inserted into the material, it forms an outwardly convex structure with an arc-shaped outer contour at the bottom of the material. In the subsequent shaping process of the material surface, the two clamping rollers feed towards the center of the material slowly in order to avoid the front end of the clamping rollers being constrained by the material. Usually, it is necessary to wait for the inner diameter of the material punched out to gradually increase before the clamping rollers can get closer to the center of the material, which makes the material shaping process take a long time.

[0005] To address the aforementioned issues, a device for assisting in the forging bearings of a forging press is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing an auxiliary forging device for a bearing forging machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary forging device for a bearing forging machine, comprising a punch and a pressure-bearing processing table, wherein a plurality of guide ridges with axes intersecting the position of the punch are fixedly arranged on the processing table, and a plurality of lower pressure rollers are arranged above the processing table. When the punch extrudes the material, the lower pressure rollers abut against the material and remain in the same position. At this time, the plurality of lower pressure rollers are distributed between adjacent guide ridges.

[0008] The present invention is further configured such that: each of the guide ridges is symmetrically arranged along the axis of the punch, the end face of the guide ridge facing the material is an arc surface, and the height of the guide ridge gradually increases from both ends to the middle.

[0009] The present invention is further configured such that: the vertical cross-section of the lower pressure roller is circular, and the diameter of the lower pressure roller gradually decreases from the end away from the punch toward the punch.

[0010] The present invention is further configured such that the included angles between the projections of adjacent guide edges and the axis of the lower pressure roller onto the same horizontal plane are equal.

[0011] The present invention is further configured to include a bracket fixedly installed on the ground, the bracket having a sliding groove, a plurality of the lower pressure rollers being fixedly installed on a lever frame, a drive source for driving the lower pressure rollers to move and abut against the material being provided at one end of the lever frame extending out of the sliding groove, and a support rod for supporting the lever frame being fixedly installed in the sliding groove.

[0012] The present invention is further configured to include a base fixedly mounted on the ground, wherein the driving source is an oil cylinder mounted on the base, and the end of the oil cylinder away from the base can be slidably extended and rotatably connected to the lever frame.

[0013] The present invention is further configured such that: a motor is fixedly installed on one side of the base, and the motor is used to drive the oil cylinder to rotate around the rotation axis of the end of the oil cylinder away from the lever frame.

[0014] In summary, this utility model has the following beneficial effects: by guiding the material and the lower pressure roller during the initial forging, the deformation position of the material is guided, so that the two clamping rollers can quickly complete the shaping of the material during the subsequent shaping process.

[0019] 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.

[0020] Auxiliary forging devices for bearing forging machines, such as Figures 1 to 3 As shown, the device includes a support fixed to the ground to support the forging hammer of the forging machine. Below the forging hammer is a pressure-bearing processing table 1. Materials and punches 2 are placed sequentially on the processing table 1 from bottom to top. Several guide ribs 11 with axes intersecting the positions of the punches 2 are fixedly installed on the processing table 1. Each guide rib 11 is symmetrically arranged along the axis of the punches 2. Several downward pressure rollers 3 are installed above the processing table 1. When the punches 2 press the material, the downward pressure rollers 3 abut against the material and remain in their positions. At this time, the downward pressure rollers 3 are distributed between adjacent guide ribs 11. In this embodiment, the material is in its initial state. When the punch 2 is embedded in the material, since the positions of several guide ridges 11 remain unchanged, the material is guided to deform by several guide ridges 11 from below. This causes the upper and lower surfaces of the material to form wavy arc surfaces with connected ends. The troughs of the wavy arc surfaces formed by the upper and lower surfaces are staggered. After the material is punched, the two clamping rollers used for shaping can more easily approach the axis of the material and clamp it along the crests and troughs of the upper and lower surfaces of the material. As the material rotates continuously, the two clamping rollers can quickly complete the shaping of the material.

[0021] like Figures 1 to 3 As shown, in order to make the wavy arc surface of the upper and lower surfaces of the material smoother, the end face of the guide rib 11 facing the material is a circular arc surface. The height of the guide rib 11 gradually increases from both ends to the middle. The vertical cross section of the lower pressure roller 3 is circular. Considering that the material deformation is outward from the axis of the punch 2, the diameter of the lower pressure roller 3 gradually decreases from the end away from the punch 2 towards the punch 2. In order to make the upper and lower surfaces of the initially forged material more uniform, the included angles of the projections of the axes of adjacent guide ribs 11 and lower pressure roller 3 in the same horizontal plane are equal.

[0022] like Figures 1 to 3 As shown, considering that the material is shaped into a cylindrical shape with different dimensions in the direction before initial forging, in order to allow the lower pressure roller 3 to abut against the material surface more effectively, the bracket is provided with a sliding groove. Several lower pressure rollers 3 are fixedly mounted on the lever frame 4. One end of the lever frame 4 that extends out of the sliding groove is provided with a drive source to drive the lower pressure roller 3 to move and abut against the material. A support rod 5 for supporting the lever frame 4 is fixedly mounted in the sliding groove. A base 7 is fixedly mounted on the ground. The drive source is a hydraulic cylinder 6 mounted on the base 7. The end of the hydraulic cylinder 6 away from the base 7 can be extended by sliding and rotatably connected to the lever frame 4. In order to further adjust the distance between the lower pressure roller 3 and the punch 2, a motor 8 is fixedly mounted on one side of the base 7. The motor 8 is used to drive the hydraulic cylinder 6 to rotate around the rotation axis of the end of the hydraulic cylinder 6 away from the lever frame 4.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
