Description

Plate multi-point forming device

technical field

A plateless multi-point forming device is a device for performing plastic processing on a plate, which belongs to the field of mechanical engineering.

Background technique

At present, plate forming is mainly realized by various presses through molds. Each part requires one or several sets of molds to complete the forming process. The traditional plate forming device has a low degree of automation, and its efficiency, processing quality and precision cannot meet the needs of modern industrial production. The plateless multi-point forming device is an advanced plate forming equipment controlled by computer. Using multiple regularly arranged, height-adjustable basic bodies (punches) to change the shape of the forming surface at will, replacing traditional molds to achieve multi-point forming of plate parts, is a fundamental reform of the existing plate forming equipment. And innovation will have a huge impact on the technological progress of my country's machinery manufacturing industry.

Contents of the invention

The purpose of this utility model is to change the traditional processing method of using a mold to form a plate, and provide a plate multi-point forming device with a blank-holding function based on a moldless multi-point forming technology that can realize automatic control.

The above-mentioned purpose of the utility model is achieved in this way, described as follows in conjunction with accompanying drawing.

The plateless multi-point forming device consists of an upper and lower basic body control unit group, an adjustment mechanism, a loading mechanism and a frame. The upper and lower basic body groups are composed of multiple adjustable basic bodies and blank holders. It can move freely along its axial direction and can be positioned at any position. The blank holder is installed on the periphery of the control unit group of the upper and lower basic bodies. The blank holder adopts multiple hydraulic cylinders, and these hydraulic cylinders can apply blank holder to the blank holder at the same time. .

Said edge holding device can adopt nitrogen cylinder or elastic material.

Said blank holder adopts flexible or rigid blank holder.

Detailed ways

Below in conjunction with the embodiment shown in the accompanying drawings, further illustrate the specific content of the utility model and its working process.

Refer to Figure 1: The plateless multi-point forming device is composed of an upper and lower basic body control unit group composed of a lower basic body control unit group 1 and an upper basic body control unit group 4, including a lower blank holder cylinder group 2 and an upper basic body control unit group. The upper and lower blankholders composed of blankholder cylinder group 5, as well as loading mechanisms 6, 7 and upper and lower blankholder rings 9, 10. The plateless multi-point forming device is connected by the upper and lower beams through four columns, the movable beam 6 slides on the four columns between the upper and lower beams, and the four columns play a guiding role; the upper and lower basic groups and the basic body are arranged around the The blank holders are respectively fixed on two large plates, the upper basic body group and the large plate are fixed on the movable beam 6 and move up and down with the movable beam 6, and the lower basic body group and the large plate are fixed on the lower beam together. When forming, the upper basic body group and the blank holder move downward with the movable beam 6, and press against the lower basic body group fixed on the lower beam to form the part.

In order to prevent defects such as wrinkling of the sheet during the forming process, some edge-holding devices that can exert pressure on the sheet before forming are added around the basic body for forming. This device can be composed of multiple upper and lower hydraulic cylinders or nitrogen springs or elastic materials. (such as a coil spring), the non-uniform distribution of the blank-holding force exerted on the blank-holding ring at the same time can realize stepless adjustment, and the blank-holding ring can adopt a rigid or flexible structure. Refer to Figures 2 and 3 for the working principle of the hydraulic cylinder (or nitrogen gas spring), and Figure 4 for the arrangement. Rigid blank holder (see Figure 3) or flexible blank holder (see Figure 2) can be realized by changing the structure of the blank holder ring. By adjusting the pressure of the hydraulic control system (or nitrogen pressure control system), the stepless control of the pressure of the blank holder is realized.

In order to meet the needs of different shapes and forming methods of plate parts, the number of upper and lower basic body control unit groups can be changed, and the number of blank holder cylinders can also be changed.
