Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling equipment technology, specifically a circlip rolling forming device. Background Technology
[0002] A plate rolling machine (also called a sheet metal rolling machine) is a mechanical device used for rolling metal sheets. It uses a series of rollers or drums to gradually roll flat metal materials into cylindrical, conical, or other specific shapes, thus achieving the forming and processing of metal sheets. Plate rolling machines are widely used in metal processing, building structures, pipe manufacturing, and other fields, and are one of the important pieces of equipment for manufacturing various metal containers, pipes, structural components, and other products. When processing narrow ring-shaped workpieces, plate rolling machines use thin metal strips as blanks. During the processing, manual loading, unloading, and adjustment of the material's position are required. This results in low efficiency for large-scale processing, and the repetitive mechanical movements over long periods can easily lead to fatigue. Utility Model Content

A support frame is fixedly installed above the base, and a magazine-type hopper is installed on the upper surface of the support frame for storing strip-shaped blanks for processing snap rings. A feeding cylinder is provided at the bottom of the support frame. Two parallel supports are fixedly installed on the base, and two lower rollers are provided and installed between the two supports. A motor a is installed on the upper side of the base, and the output end of motor a... The lower roller is driven to rotate. Multiple columns are fixedly installed on the upper side of the base. A top plate is fixedly installed on the top of each column. A longitudinal unloading cylinder is fixedly installed on the upper side of the top plate. A downwardly extending push plate is fixedly installed at the output end of the unloading cylinder. A U-shaped notch is provided on the lower side of the push plate. A sliding lifting plate is installed between the columns. A motor b is installed on the upper side of the lifting plate. The output end of the motor b is connected to the upper roller. A lifting cylinder is installed on the upper side of the base to push the lifting plate to adjust its height.
[0005] Preferably, the piston rod of the feeding cylinder is fixedly mounted with an L-shaped push rod, which is slidably connected to the bottom of the hopper, and the push rod moves laterally to push out the bottom strip of blank.
[0006] Preferably, an inclined ejector bar is mounted on the front side of the lifting plate via a bracket, with the root of the ejector bar located directly above the upper roller. After the lifting plate moves up, the ejector bar engages with a U-shaped notch.
[0007] Preferably, the outer side of the upper roller is provided with an annular groove, and the annular groove is on the same vertical plane as the discharge port at the bottom of the hopper.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is used for roll forming of retaining rings. The blank is automatically conveyed between the upper and lower rollers. After roll forming, the retaining ring is lifted and pushed forward by the unloading cylinder, sliding downwards along the unloading rod for discharge. This device realizes automatic processing of retaining rings, which helps to improve production efficiency. Attached Figure Description

[0012] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0013] Please see Figure 1-2 This utility model provides a technical solution: a snap ring rolling forming device, including a base 1, an upper roller 12 and a lower roller 6. A support frame 2 is fixedly installed above the base 1. A magazine-type hopper 3 is installed on the upper surface of the support frame 2. The hopper 3 is used to store strip-shaped blanks for processing snap rings. A feeding cylinder 14 is provided at the bottom of the support frame 2. An L-shaped push rod 15 is fixedly installed on the piston rod of the feeding cylinder 14. The push rod 15 is slidably connected to the bottom of the hopper 3. The push rod 15 moves laterally to push out the bottom strip-shaped blank (the bottom of the hopper 3 is provided with a horizontally penetrating discharge hole). After the bottom blank is pushed out, the blanks above fall down under the action of gravity to replenish it.
[0014] Two parallel supports 5 are fixedly installed on the base 1. Two lower rollers 6 are provided and installed between the two supports 5. A motor a4 is installed on the upper side of the base 1. The output end of the motor a4 drives the lower rollers 6 to rotate. Multiple columns 9 are fixedly installed on the upper side of the base 1. A top plate 7 is fixedly installed on the top of the column 9. A longitudinal unloading cylinder 10 is fixedly installed on the upper side of the top plate 7. A downwardly extending push plate 11 is fixedly installed on the output end of the unloading cylinder 10. A U-shaped notch is provided on the lower side of the push plate 11. After being rolled into a round shape, the retaining ring workpiece is pushed forward by the unloading cylinder 10. A sliding lifting plate 8 is installed between the columns 9. A motor b is installed on the upper side of the lifting plate 8, and the output end of the motor b is connected to the upper roller 12. A lifting cylinder is installed on the upper side of the base 1 to push the lifting plate 8 to adjust its height. An annular groove is provided on the outer side of the upper roller 12. The annular groove is on the same vertical plane as the discharge port at the bottom of the hopper 3. After the billet is discharged from the hopper 3, it fits and engages with the annular groove. An inclined ejector rod 13 is installed on the front side of the lifting plate 8 through a bracket. The root of the ejector rod 13 is located directly above the upper roller 12. After the lifting plate 8 moves upward, the ejector rod 13 engages with the U-shaped notch.
[0015] Working principle: The strip-shaped billet is loaded from the upper port of the hopper 3. The feeding cylinder 14 pushes the billet out one by one. The billet is clamped between the upper roller 12 and the lower roller 6. The upper roller 12 and the lower roller 6 are driven by motors to rotate and achieve rounding. The rolled and formed retaining ring wraps around the unloading rod 13. Then the lifting plate 8 is pushed up and the unloading rod 13 is inserted into the notch under the push plate 11. The unloading cylinder 10 extends and pushes the retaining ring to slide forward to discharge the material.
