Description

Technical Field

[0001] This utility model relates to the field of U-shaped snap ring processing technology, and in particular to a U-shaped snap ring pressing tool. Background Technology

[0002] U-shaped retaining rings are widely used in many industries such as construction, decoration, furniture, automobiles, and machinery manufacturing. In the production process, in order to save costs, steel plates are usually pressed and formed using molds and tooling. If the U-shaped groove of the tooling is designed to be the same size as the U-shaped plate, the size of the U-shaped retaining ring will be too large due to the springback characteristics of the steel plate; if the U-shaped groove of the tooling is designed to be too small, the U-shaped retaining ring will not be easy to detach from the tooling after being pressed and formed. In view of the above, it is necessary to improve the existing U-shaped snap ring tooling structure so that it can meet the current needs of U-shaped snap ring manufacturing and use. Utility Model Content

[0012] To facilitate a clearer understanding of this technical solution for those skilled in the art, the following will be described in conjunction with the appendix. Figure 1-3 Detailed explanation of the specific structure and principle of this technical solution: A U-shaped retaining ring pressing fixture includes a first insert 1, second inserts 2 symmetrically arranged on both sides below the first insert 1, a plurality of first elastic mechanisms symmetrically arranged on the second inserts 2 on both sides, a third insert 5 disposed between the second inserts 2 on both sides, a plurality of second elastic mechanisms disposed below the third insert 5, and a fourth insert 7 disposed below the second elastic mechanisms. The second inserts 2 on both sides are joined in a U-shape. The first insert 1 and the fourth insert 7 are mounted on a press. One end of the first elastic mechanism is connected to the second insert 2, and the other end of the first elastic mechanism is connected to the fourth insert 7. One end of the second elastic mechanism is connected to the third insert 5, and the other end of the second elastic mechanism is connected to the fourth insert 7. The fourth insert 7 has a U-shaped groove, and the second inserts 2 on both sides are installed in the U-shaped groove of the fourth insert 7. The bottom dimension of the first insert 1 is larger than its neck dimension, and the bottom of the second insert 2 is larger than its neck dimension. The outer corners are rounded. During operation, the steel plate 9 to be processed is placed on the working surface, between the second inserts 2 on both sides. The press presses the first insert 1 downwards. The first insert 1 first contacts the steel plate 9, and then continues to press downwards. The third insert 5 is subjected to the pressure of the first insert 1. During the downward pressing process, the third insert 5 will press down on the second inserts 2 on both sides. The contact surface between the second insert 2 and the third insert 5 moves downwards. At this time, the rounded corners at the bottom of the second insert 2 form an angle rotation, so that the steel plate 9 forms a U-shape with both ends towards the middle. Then, the press is controlled to lift the first insert 1 upwards. After the first insert 1 is removed, the pressure is released. The first elastic mechanism pulls the second insert 2 to both sides. The second elastic mechanism acts on the third insert 5, lifting the third insert 5 upwards. At this time, the U-shaped steel plate 9 pops upwards, forming demolding. Due to the rebound energy of the steel plate 9 and the return of the first insert 1 to the middle U-shaped retaining spring, it will return to the normal U-shaped retaining spring we need.

[0013] The structure of the first elastic mechanism will be described in detail below. The second insert 2 has multiple screw mounting threaded holes on its side, and the fourth insert 7 has multiple first spring 3 mounting holes on its side. The first elastic mechanism includes a plug screw 4 and a first spring 3 sleeved on the plug screw 4. The plug screw 4 is installed in the screw mounting threaded hole. One end of the plug screw 4 is connected to the second insert 2, and the other end is installed on the fourth insert 7. One end of the first spring 3 is connected to the plug screw 4, and the other end is connected to the fourth insert 7. The second insert 2 and the fourth insert 7 are connected through the first spring 3 and the plug screw 4, wherein the first spring 3 is in a stressed state. When the first insert 1 acts downward, the second insert 2 rotates, and the first spring 3 is in a stressed state. After the first insert 1 is removed, the first springs 3 on both sides cause the second insert 2 to move to both sides, completing the reset. The first elastic mechanism, screw mounting threaded holes, and first spring 3 mounting holes are provided in the same number.

[0014] The structure of the second elastic mechanism will be described in detail below. The bottom of the fourth insert 7 has multiple mounting holes for the second springs 6. The second elastic mechanism includes multiple second springs 6 located below the third insert 5. Each second spring 6 is installed in a mounting hole and one end is connected to the fourth insert 7. The other end is located below the third insert 5 and is subjected to pressure from the third insert 5. During operation, when the first insert 1 presses down on the third insert 5, the second spring 6 is subjected to pressure from the third insert 5. After the first insert 1 is removed, the second spring 6... 5 provides an upward force to lift it upward, thereby causing the product on the third insert 5 to spring back and complete demolding; wherein, the bottom of the fourth insert 7 is provided with multiple bolt mounting thread holes, the third insert 5 is provided with multiple internal hexagon thread mounting holes, and an internal hexagon bolt 8 is provided between the fourth insert 7 and the third insert 5. The bottom of the internal hexagon bolt 8 is installed in the bolt mounting thread hole, and the top of the internal hexagon bolt 8 is installed in the internal hexagon thread mounting hole. The fourth insert 7 and the third insert 5 are connected by the internal hexagon bolt 8.

[0015] The third insert 5 has a T-shaped cross section, and the inner sides of the second inserts 2 on both sides are symmetrically provided with steps for installing the third insert 5. When the first insert 1 acts downward on the third insert 5, the third insert 5 can act on the second inserts 2 on both sides simultaneously through the structure between it and the second inserts 2 on both sides, so that the second inserts 2 on both sides work at the same time, thereby improving the processing dimensional quality.

[0016] The overall working principle of this utility model will be explained in detail below: The tooling of this design divides the U-shaped groove into two parts, namely the second insert 2 with symmetrical design on both sides in this technical solution. During the pressing process, when the second insert 2 is subjected to pressure, it presents a U-shape with both ends moving towards the middle. After the first insert 1 is removed, due to the elastic force of the first spring 3, the second insert 2 on both sides is pulled apart to both sides, and the second spring 6 exerts an upward force on the third insert 5, thereby popping the product out, thus obtaining the product we need.

[0017] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
