Description

One-time forming mold for a ring

technical field

The utility model relates to the technical field of mold design, in particular to a one-time forming mold for a circular ring, which is used for forming a mounting sleeve at the outer end of a stabilizer bar.

Background technique

With the continuous development of social economy, automobiles are becoming more and more popular. Automobiles are no longer just a means of transportation in the traditional concept, and people have higher and higher requirements for their performance and cost. The stabilizer bar is an indispensable structural part on the car chassis. If the ring parts can be formed at one time, the production cost of the stabilizer bar will be reduced.

And the process of wrapping the stabilizer bar with the bending ring is particularly important. The general method of punching and bending rings is shown in Figure 1. First, the product 2 is pressed into a U shape, and then the product 2 is buckled on the stabilizer bar, and then the product 2 is pressed into a ring shape. This solution requires two working steps, which affects production efficiency, so a new process structure is required.

Contents of the invention

The purpose of the utility model is to provide a ring forming mold at one time, and the technical problem to be solved is how to bend the ring at one time to improve production efficiency.

The circular ring primary molding die described in the utility model comprises an upper pressing block, a lower pressing block, a punch, a die, an insert block and a slider; Below the upper pressing block; a strip product is set between the upper pressing block and the lower pressing block; a lower template is arranged under the lower pressing block, and the punch is set in the extending direction of the strip product and is located between the upper pressing block and the lower pressing block. One side of the pressing block; the die is set under the punch; the slider is set under the side of the strip product; the insert is set at the end of the slide; the upper die is set on the top of the punch and the insert.

The pressing plate can push the upper pressing block, the lower pressing block and the strip-shaped product to move down together; the upper pressing block can press the strip-shaped product into a U shape.

The upper die can drive the insert to move down, the insert can push the slider to move in translation, and the slide can push the U-shaped opening of the strip product to reduce the opening.

The upper die can drive the punch to move down, and the punch can press the U-shaped strip product into a circular shape.

The upper mold can drive the punch and the insert to move up, the slider can return under the action of the spring, the upper mold can also drive the pressing plate to continue to move up, and drive the upper and lower pressing blocks to move up until separate.

The cutting edge of the punch is two protruding hooks.

The inside of the concave mold is provided with a square cavity, the square cavity inside the concave mold matches the shape of the punch, the punch can slide in the cavity, and the two sides of the square cavity have knife-edge grooves for cutting material, which are hooked with the punch The knife edge on is tangent.

Described upper briquetting block and lower briquetting block are made of 45# steel.

The punch, die, insert and slide block are made of Cr12MoV.

The technical solution of the utility model has the following advantages:

When the circular ring forming mold described in the utility model is bent round, the product is placed on the lower pressing block, and the upper pressing block presses down to drive the product to move down, pressing the bar into a U shape, and continuing to press down, the slider and The punch presses the U shape into a ring to complete one-time molding, thereby improving production efficiency.

Detailed ways

The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Fig. 2 to Fig. 5b, the circular ring one-time molding die described in the utility model includes an upper pressing block 1, a lower pressing block 2, a punch 3, a die 4, an insert block 5 and a slider 6; The briquetting block 1 and the lower briquetting block 2 are made of 45# steel, and the punch 3, the die 4, the inserting block 5, and the slide block 6 are made of Cr12MoV.

A binder plate is arranged above the upper briquetting block 1, and the lower briquetting block 2 is arranged below the upper briquetting block 1; a strip product is arranged between the upper briquetting block 1 and the lower briquetting block 2; the lower briquetting block 2 A lower template is provided below, and the punch 3 is arranged on the extension direction of the strip product and is located on one side of the upper pressing block 1 and the lower pressing block 2; the concave die 4 is arranged under the punch; the slider 6 is arranged on the strip The lower side of the product; the insert block 5 is set at the end of the slider 6; the upper die is set on the top of the punch and the insert block.

When the circular ring primary molding die described in the utility model is in use, the upper pressing block 1 moves down with the pressing plate, and the upper pressing block presses the strip-shaped product onto the lower pressing block 2, and the pressing plate pushes the upper pressing block 1 , the lower pressing block 2, and the strip-shaped products move down together. At this time, the upper pressing block 1 presses the strip-shaped products into a U shape. At this time, the lower pressing block 2 pushes to the lower template, and the upper mold continues to move down, driving the inserting block 5 to move down. , the insert block 5 pushes the slider 6 to move in translation, and the slider 6 pushes the U-shaped opening of the strip product to reduce the opening opening. The shaped product is pressed to a round shape, and the pressing stroke ends. Then the upper die drives the punch 3 and the insert 5 to move up, and the slide block 6 returns under the action of the spring (the return of the spring belongs to the prior art, for example, one end of the spring is fixedly connected to the fixed block on the outside of the insert 5, and the spring The other end of the plug is connected to one side of the slider 6. When the plug 5 moves down and pushes the slider 6 to translate, the spring is stretched; when the plug 5 moves up, the elastic force of the spring automatically prompts the spring to retract. The slide block 6 returns under the action of the spring), the upper die drives the clamping plate to continue to move upward, the upper pressing block 1 and the lower pressing block 2 move upward until they are separated, and the product is removed, and a stamping stroke ends.

Wherein, the punch is made as shown in Figure 3, and the cutting edge of the punch is two protruding hooks, which extend into the product to remove excess material inside the product.

The concave mold is made as shown in Figure 4. The square cavity inside the concave mold matches the shape of the punch. The punch can slide in the cavity. The knife-edge grooves for cutting materials are opened on both sides of the square cavity, and the knife-edge on the hook of the punch Tangent, completes the removal of product material.

Although the utility model has been described in detail with general description and specific examples above, some modifications or improvements can be made on the basis of the utility model, which will be obvious to those skilled in the art. Therefore, the modifications or improvements made on the basis of not departing from the spirit of the utility model all belong to the protection scope of the utility model.
