Description

A bending mold

technical field

The utility model belongs to the technical field of sheet metal processing, in particular to a bending die.

Background technique

With the development of the national economy and the continuous improvement of the people's material and cultural level, more and more sheet metal products have entered people's lives, with ever-changing structures and products becoming more and more complex. In order to improve productivity and reduce costs, molds have also been vigorously developed and promoted, and are easy to operate and stable in size. The new bending mold adjusts the mold structure according to the shape and technical requirements of the product. Eight sides of the product are bent at the same time. No bending marks are allowed on the surface of the bent edge. Dimensional stability also needs to be considered, which adds a lot of difficulty to the mold making. However, the bending machine needs to be processed and formed 8 times, and the labor cost is high.

A spring box 15 is provided between the bearing plate 16 and the lower beating plate 14, and the outer guide post 11 is divided into a guide post and a guide sleeve. Base 1 is the reference hole, the inner guide post 4 is installed on the upper die base 1, the spring box 15 is connected to the lower stripping plate 13 by the ejector pin, and the product 12 is placed on the lower stripping plate 13.

The upper molding block 3 is a dovetail-shaped slide rail, and the pin 9 is a template reference hole, which is convenient for positioning during the assembly process and prevents installation deviation. The stripping plate 13 is used for product positioning before bending and product unloading after bending. The inner guide column 4 ensures the concentricity of the upper and lower molds to prevent intermittent deviation. The spring box 15 ensures the flatness of the product and prevents the product from changing during bending. The product after forming Break away from the lower bend block.

Put the flat product into the mold, move the mold up and down on the working table of the stamping machine tool, and the upper forming block 3 and the lower stripping plate 13 fix the product to perform 90-degree bending along the lower bending block 5R angle. After bending, because the product is in a U-shape, the upper forming block is made into a dovetail-shaped slide rail with a certain angle. The bending block will move along the punching machine table, and the size of the upper forming block will also change accordingly. The mold is in the closed state during the bending process, and the forming block is at the maximum size; when the stamping table rises and there is a gap between the lower surface of the product and the stripper plate of the lower mold, the forming slider of the upper mold will be in the initial state of mold opening, and the size of the forming block will gradually become smaller , the product is separated from the forming slider, which is convenient for taking the product.

Beneficial effects of the utility model: the utility model can realize aluminum plate (thickness 0.8-3.0mm) or steel plate (thickness 0.5-2.5mm) bending edge length in 10.0mm-40.mm bending forming, realizes multilateral bending once Forming, improve production efficiency, and easy to operate, stable size.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Example 1

A kind of bending mold, as shown in Figure 1, comprises upper mold forming assembly, lower mold bending block assembly, upper mold base 1 is provided with upper splint 2, upper molding block 3, upper backing plate 10 in the upper mold forming assembly, In the lower mold bending block assembly, the lower mold base 7 is provided with a lower splint 6, a lower bending block 5 and a lower stripping plate 13, and the other side of the lower mold base 7 and the lower bearing plate 16 are provided with a lower pad 8 and The lower beating plate 14, the spring box 15 is arranged between the lower supporting plate 16 and the lower beating plate 14, the outer guide post 11 is divided into a guide post and a guide sleeve, the guide post is assembled on the lower die base 7, and the guide sleeve is installed on the upper die base 1, The pin 9 is located in the upper die base 1 reference hole, the inner guide column 4 is installed on the upper die base 1, the spring box 15 is connected with the lower stripping plate 13 by the push rod, and the product 12 is placed on the lower stripping plate 13.

The upper forming block 3 is a dovetail slide rail. The pin 9 is the template reference hole, which is convenient for positioning during assembly and prevents installation deviation. The outer guide column 11 can guide the upper and lower molds to prevent machine tool vibration from causing deviation of the upper and lower molds. The lower stripping plate 13 is used for product positioning and bending before bending. The final product unloading function, the inner guide column 4 ensures the concentricity of the upper and lower molds to prevent intermittent deviation, the spring box 15 ensures the flatness of the product to prevent the product from changing during bending, and the product is separated from the lower bending block after forming.

Put the flat product into the mold, move the mold up and down on the working table of the stamping machine tool, and the upper forming block 3 and the lower stripping plate 13 fix the product to perform 90-degree bending along the lower bending block 5R angle. After bending, because the product is in a U-shape, the upper forming block is made into a dovetail-shaped slide rail with a certain angle. The bending block will move along the punching machine table, and the size of the upper forming block will also change accordingly. The mold is in the closed state during the bending process, and the forming block is at the maximum size; when the stamping table rises and there is a gap between the lower surface of the product and the stripper plate of the lower mold, the forming slider of the upper mold will be in the initial state of mold opening, and the size of the forming block will gradually become smaller , the product is separated from the forming slider, which is convenient for taking the product.

As shown in Figure 2-6, put the processed flat product into the positioning of the stripping plate 13 of the lower die assembly, start the machine tool, and the upper die forming assembly will move downwards along with the stamping worktable. Firstly, the outer guide column 11 will The structure of the upper and lower molds is guided. With the lowering of the table, the inner guide column 4 is precisely connected to the upper and lower molds. The lower stripping plate 13 relies on the spring pressure to fix the product to prevent the product from being biased during the molding process; at the same time, the upper molding block 3 slides The block is in the closed mold state, and the upper forming block 3 and the lower stripping plate 13 push and fix the product to bend along the R angle of the lower bending block. When the worktable surface rises after forming, the lower mold assembly makes the product break away from the lower bending block 5 through the thrust of the spring box 15, and the upper surface of the product separates the product through the upper forming block 3.
