Description

A new type of differential strength plate forming device

technical field

The invention belongs to the technical field of thermoforming molds, and in particular relates to a novel differential plate forming device.

Background technique

Thermoforming stems from the ever-increasing demands on the crash safety of automobiles and, at the same time, the stricter and stricter limits on the carbon dioxide emissions of automobiles. Therefore, people have to work on a production process for auto parts that is lighter in weight and higher in strength. At the same time, people's demands for the appearance and quality of automobiles gradually increase, and the complexity of auto parts also increases. Due to the increased demand for collision tests, unequal strength thermoforming parts came into being. However, due to the difficulty of making unequal strength thermoforming molds, the long cycle and high cost, it is often difficult to popularize and use.

The present invention solves the defects existing in the background technology, and the present invention has the following beneficial effects:

In the present invention, a box is arranged outside the heating furnace box, and a heating module and a temperature control module are arranged inside the box, so that the thermoforming sheet metal parts can be heated at different positions to meet the temperature requirements of different parts. It needs to be designed according to a simple soft mold, does not need to design a heating device, simplifies the production steps, shortens the production cycle of the mold, and reduces the cost.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments;

1 is a schematic diagram of the overall structure of a preferred embodiment of the present invention;

In the figure: 1. Heating furnace box; 2. Box body; 3. Supporting plate; 4. Supporting block; 5. Furnace door; 6. Sheet metal parts.

Detailed ways

The present invention will now be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

As shown in Figure 1, a new type of differential plate forming device includes a heating furnace box 1 and a box body 2 located outside the heating furnace box 1; the heating furnace box 1 is provided with a support plate 3, and both sides of the box body 2 are provided There is a support block 4, the support block 4 and the support plate 3 are located on the same line, and the box body 2 is provided with a heating module and a temperature control module.

In this embodiment, a box body 2 and a support block 4 are installed on the furnace door 5 of the heating furnace box 1 , and the support block 4 can support the sheet metal parts 6 to be heated, while the heating module in the box body 2 and the temperature control The module can effectively heat the sheet metal parts 6. When the sheet metal parts 6 are heated in the heating furnace box 1 and on the box body 2 at the same time, the temperature adjustment of the local area can be realized. When the sheet metal parts 6 are in two positions They are respectively heated to the set temperature and then moved to the mold for molding, thereby avoiding setting a heating device on the thermoforming mold, simplifying the steps of the thermoforming mold, shortening the mold production cycle, and reducing the cost.

Specifically, conventional sheet metal parts 6 with different strengths are uniformly heated to 930° C. in the heating furnace 1, and then a heating device is set on the thermoforming mold to differentiate the temperature of the sheet metal parts 6 to achieve different The present invention can make the high-strength area of the sheet metal part 6 heated to 930°C in the heating furnace box 1, and the low-strength area to be heated to 800°C at the position of the furnace door 5, thereby realizing the heating of the sheet metal part 6 temperature difference.

In this embodiment, a furnace door 5 is provided at the exit position of the heating furnace box 1 .

Specifically, both the box body 2 and the support block 4 are located on the furnace door 5 .

In this embodiment, both the support plate 3 and the support block 4 are made of alloy materials.

Specifically, the support plate 3 and the support block 4 are both copper-nickel alloys.

In this embodiment, the heating module is a heating tube, and the temperature control module is a temperature controller.

All in all, in the present invention, a box body 2 is arranged outside the heating furnace box 1, and a heating module and a temperature control module are arranged in the box body 2, so that the thermoforming sheet metal parts 6 can be heated at different positions to meet the temperature requirements of different parts, By adopting the invention, the mold only needs to be designed according to a simple soft mold, and no heating device needs to be designed, the manufacturing steps are simplified, the mold manufacturing cycle is shortened, and the cost is reduced.

The ideal embodiments of the present invention are inspired by the above, and relevant persons can make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
