Abstract

A method for producing a metal ring comprises the following steps: mounting a metal plate on a press; punching the plate at least twice to form a metal ring; using an upper mold and a lower mold to press the metal ring a few times; mounting the metal ring in a polishing machine to remove burrs on the ring; punching and pressing the metal plate to form an integral metal ring in order to increase the reliability of the metal ring.

Description

523431 V. Description of the invention (1) [FIELD OF THE INVENTION The present invention relates to a method for punching a metal substrate with a punch for making a metal ring, and in particular, it relates to punching in a mold set to make two turns. The metal ring is placed in the ring to enhance the metal ring with a reliable shape and a smooth surface when used.

[Previous technology] X custom metal ring manufacturing method is to form a ring first, weld the gap of the ring, 'rust steel wire or iron wire after cutting the protruding solder of the elbow joints to form 6 敕 private use of manual grinding The ring is missing the metal ring notched and welded; the ring is finished, but the joint at the mouth is slightly larger or slightly smaller than the metal ring. The lack of pain ^ ^ Machine-assisted cutting and bending metal #, the cost is extremely south. In addition, the metal ring is set on the micro, two ^

Reliability. Connected ... The pump is broken and cannot be lifted. I used a conventional metal ring manufacturing method. It was a new patent case of "Automatic feeding device for metal ring welding" in National Patent Gazette Bulletin No. 274244, August 1 (1984). . The metal ring welding automatic feeding device is arranged between the metal ring winding machine and the spot welding machine, and a slipper is provided on the operating platform of the automatic feeding device, and the slide ring is correspondingly provided with the metal winding ring. In the connection position of the machine, the slideway is close to the automatic feeding device. A feeding slideway is provided, and a stopper is provided between the slideway and the feeding slideway. The working platform is provided with a feeding plate. The working platform is provided with a pedestal step by step. The pedestal has a rotatable wheel body. A driven wheel is pivotally arranged on the feed slide. The wheel body can drive the driven wheel with

Description of the invention (2) Directional rotation; the plate, the guide slide and a guide frame; falling, the metal and the metal ring to drive the gold The notch end, the feed control, the connection, and the completion of the mechanical automatic No. 274244 not only can not be damaged, in view of the plate punched into a ring and stamped to form a metal ring reliability [ Summary of the invention The main punch of the present invention is to make the metal ring into a circle by the upper die, so that the end plate of the pedestal is locked at the metal ring by the spot welding of the metallization device which locates the metal ring to the metal ring plate. Moreover, the end of the pillar is formed into a curved metal and enters the lower side of the guide slide guide frame between the moving wheels, and is equipped with automatic transmission. The announcement metal ring ring is provided with a positioning and positioning pillar top ring winding machine to complete the complete machine made of the stopper, the wheel body, and the rolling ring to facilitate the ring to pass through the notch end of the pillar ring which is set on the pillar ring. Only one metal ring can be welded at a time. The above-mentioned one-piece metal ring can not be improved. Instead of using the conventional method, the present invention not only enhances the metal hair style, but also uses the ring. Disadvantages of the metal ring, the ring, the reuse of gold, has the raw positioning support surface of the lifting ring, the curved ring from the feeding slide, the motor is turned into the gold lead and the closing control element to the spot welding 274244 The deformation of the finished product's metal ring and its production speed. The die set used for the punch belongs to the lack of the metal ring production speed. There is a guide surface that is connected to the slideway. At this time, the program machine that moves the wheel body is a ring on the feeding plate for welding. Although the notice is not good, it is easy to break. The method of using a metal base with the gold opening can provide a method for manufacturing a metal ring, which uses less secondary punching to form a metal ring. The metal ring die is punched several times to form a square ring. Reliability and production of stamping with k liter metal rings

The power of speed. According to a public step a of the present invention, a method for manufacturing a metal ring is provided. The method includes placing the following zigzag substrate on the oil ring. The metal ring is sharply punched at least twice to form a ring. Metal ring The metal ring is placed on the upper puller and lower die for several times of punching; punching and punching are made into _ q to remove burrs; the metal substrate is used in advance for reliability. _, Type metal ring to enhance the metal ring [Explanation of the invention] * In order to make the invention

It is indeed understood that the following description of Jiang a, his purpose, characteristics, and advantages can be made clearer. A detailed description of the preferred embodiment of the present invention will be given in conjunction with the attached drawings. I I use brakes, receive s basin plates at least-+ IV, the tool mainly uses a punch to form the metal base, which is strictly punching, the upper mold and the lower mold are punched several times into one body and used reliably. The invention has the advantages of improving the production speed of the metal ring: ^ 1 figure shows the first step of the method for manufacturing the metal ring of the present invention, the three-dimensional schematic diagram of forming the metal hole into the ring; Figure 2 a shows the method for manufacturing the metal f-ring of the present invention A side cross-sectional view of a metal ring placed in the first stamping die set and punched uranium; FIG. 2B illustrates a side cross-sectional view of the metal ring manufactured in the metal ring manufacturing method of the present invention before being placed in the second stamping die set; Figure 2C reveals a side sectional view of a metal ring with a burr after punching in the method for manufacturing a metal ring according to the present invention; Figure 3A illustrates a schematic diagram of the working principle of a grinding machine for the method for manufacturing a metal ring according to the present invention; Figure 3B Reveal the invention A method of manufacturing a metal ring in a grinding tank to remove burrs

Description of the invention (4) ----- Gudi 4 shows the method of manufacturing the metal ¥ ring of the present invention after grinding Side sectional view of the finished metal ring. As shown in Figures R ?, Figures 1, 2 A, and 2 B, the metal substrate 1 to which the metal ring manufacturing method of the present invention is applied is preferably a non-embroidered steel plate or an iron plate. Edge indication] At least two or more punchings, the punching process is first punched to form a small hole, and then the large hole is punched, 2 to make the metal ring, and 3 are integrally formed by the second punching process. At this time, the gold ring Ring 丨 3 is a ring with a vertical surface [such as the metal ring 1 3 in Figure 2A]. The metal ring 1 3 is placed in the die set 2 for the first stamping to form a square corner edge. Angle [such as the metal ring 13 in Figure 2B]. Please refer to Figures 2A and 2B again. The mold group 2 may be more than one group. They each include a lower mold 21 and an upper mold 22, and the lower mold 21 and the upper mold 22 are each provided with a ring-shaped recess. The grooves 211 and 221 have rounded corners or arced corners. The groove 2 11 is for the metal ring 1 3 to be placed, and the groove 2 2 1 is punched from the top to the metal ring 1 3 corresponding to the groove 2 11. The rounded corners or arced corners successively modify the vertical surface of the metal ring 13 to form a circular surface [such as the metal ring 13 of FIG. 2C]. Please refer to FIG. 2C. After the metal ring 1 3 is pressed several times, a burr 1 3 1 protruding laterally is produced. In order to eliminate the burr 1 3 1 and make the surface of the metal ring 1 3 arc-shaped The metal ring 1 3 is placed in a grinder 3, and the grinder 3 rolls and rubs against each other by vibration [as shown in FIG. 3A], and a grinding tank 31 of the grinder 3 is placed Triangular and other different shaped grinding blocks 3 11 [as shown in Figure 3B], the grinder 3 makes
