Description

Technical Field

[0001] The utility model relates to the field of automated processing, in particular to a ring rolling component. Background Art

[0002] Among automobile spare parts, rings are a commonly used part. The processing procedure is to bend a sheet plate into a quasi-circular shape, weld the edges, and then use a rounding die to perform a rounding operation so that the overall roundness meets the process requirements. At present, the manufacture of automobile rings usually adopts a specific rolling die combined with punches arranged in multiple directions to achieve multi-directional rolling operations. For example, the continuous forming die of the ring in patent CN115229055A can realize continuous bending processing of the profile through a multi-stage forming core combined with multiple offset bending components to finally form a ring.

[0003] This type of processing requires a complex mold structure and is costly. Utility Model Content

[0004] Purpose of the utility model: In order to solve the deficiencies of the prior art, the utility model provides a ring rolling component, which not only realizes continuous processing but also does not require a practical and complicated mold structure and has low cost.

[0005] The technical solution adopted by the utility model is as follows: a ring rolling component is installed on a cabinet, including a rolling guide block, a cutting component and a limiting component. The bottom of the rolling guide block has a quarter arc surface, and the arc surface has a guide groove. One end of the guide groove is in a horizontal state, connected with the front end feeding component so that the material strip enters the guide groove horizontally, and the other end of the guide groove is in a vertical state. The limiting component includes a movable seat and a limiting block. The limiting block is fixed on the movable seat and is located directly below the vertical end of the guide groove. The cutting component includes a cutter and a driving member for controlling the cutter. The cutter and the limiting block are arranged opposite to each other, and the rolled material strip is located between the cutter and the limiting block. The cutter is controlled to retract and retract by the driving member to cut and separate the wound ring from the material strip.

[0006] Preferably, ribs are provided on both sides of the guide groove to confine the material strip within the guide groove.

[0007] Preferably, the movable seat comprises a fine-tuning screw and an adjusting block which moves laterally following the fine-tuning screw, and the limit block is fixed on the side of the adjusting block.

[0008] Preferably, the driving member is a pneumatic cylinder or an electric cylinder.

[0009] Beneficial effects: The circular ring rolling component disclosed by the utility model has the following effects: the flat loading belt is rolled into a circle to form a circular ring through the quarter arc at the bottom of the rolling guide block, and then the cutting operation is realized in conjunction with the cutter and the limit block. The entire component structure is simple and low in cost, and continuous processing can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] The utility model discloses a ring rolling component, which is installed on the cabinet of the automatic production line, and its front end is a feeding component, and the rear end is a trimming component. The specific structure is as follows Figure 1~2 As shown, it includes a rolling guide block 1, a cutting component 2 and a limiting component 3, wherein the rolling guide block rolls the horizontally fed material strip 4 into a circle, and the cutting component and the limiting component are arranged opposite to each other to cut the wound ring to separate it from the material strip.

[0015] Specifically, the rolling guide block is fixed on the cabinet, and its bottom has a quarter arc surface 11, and a guide groove 12 on the arc surface. One end of the guide groove is horizontal and connected to the front end feeding component, while the other end of the guide groove is vertical. The feeding component feeds the material strip into the guide groove horizontally, and bends it along the curvature of the guide groove, and finally rolls it into a circle. Guard edges 13 are provided on both sides of the guide groove. The guard edges on both sides form a barrier to the material strip in the guide groove to prevent the material strip from escaping from the guide groove during the bending process.

[0016] Since the bottom of the winding guide block is a quarter arc surface, the material strip can form a quarter arc when it is bent along the arc. As the material strip continues to be transmitted, each section of the material strip entering the winding guide block is bent into a quarter arc, and a complete circle is formed after winding one circle.

[0017] The limit assembly includes a movable seat 21 and a limit block 22. The limit block is located directly below the vertical end of the guide groove and the left and right positions are adjusted by the movable seat. The movable seat includes a fine-tuning screw 23 and an adjustment block 24 that moves laterally following the fine-tuning screw. The limit block is installed on the adjustment block. The cutting assembly includes a cutter 31 and a driving member 32 for controlling the cutter. The cutter and the limit block are arranged opposite to each other, and the bent material strip is located between the cutter and the limit block. The cutter is controlled to move laterally by the driving member to cut the material strip. At this time, the limit block plays a bearing role during cutting.

[0018] The limit block is adjusted to the left and right positions by fine-tuning the lead screw and the adjusting block during use, so that it just sticks to the side of the material strip. When the material strip is wound into a circle, its free end is located above the limit block (such as Figure 3 as shown).

[0019] The cutting assembly includes a fixed seat 33, a driving member vertically installed on the fixed seat, and a cutter that can be laterally slidably assembled on the fixed seat. The cutter and the driving member are coordinated through a reversing structure (not shown in the figure), so that the vertically retractable driving member can control the lateral movement of the cutter. The specific driving member can be a cylinder or an electric cylinder, and the reversing structure can be a structure of a wedge block and a return spring. When the driving member is extended, the wedge block controls the cutter to extend. When the driving member is retracted, the return spring drives the cutter to retract. This structure belongs to a conventional technical solution and can refer to the existing technology, so it will not be described here.

[0020] The utility model discloses a ring rolling component, which allows a flat loading belt to be rolled into a circle to form a ring through a quarter arc at the bottom of a rolling guide block, and then cooperates with a cutter and a limit block to realize the cutting operation. The entire component has a simple structure and low cost, and can realize continuous processing.

[0021] The technical content and technical features of the utility model have been disclosed as above. However, technicians familiar with the field may still make various substitutions and modifications without departing from the spirit of the utility model based on the teachings and disclosures of the utility model. Therefore, the protection scope of the utility model should not be limited to the contents disclosed in the embodiments, but should include various substitutions and modifications without departing from the utility model and be covered by the claims of this patent application.
