Embodiment 1

[0043] Such as image 3 As shown, the heat transfer plate forming device is composed of a power supply system 1 , a single-turn electromagnetic driver 2 , a blank holder unit 3 , a conductive electrode 4 and a mold 5 . The single-layer single-turn electromagnetic driver 2 includes a metal sheet 2-1-1 and a skeleton 2-2, and the metal sheet 2-1-1 and the skeleton 2-2 are attached to each other. The single-layer single-turn electromagnetic driver includes multiple single-step electromagnetic drivers. The number of single-step electromagnetic drivers is determined according to the number of forming steps of the workpiece to be formed. The number of forming steps of the workpiece to be formed is determined according to the actual needs of the forming depth and shape of the workpiece. The shape of the side of the single-step electromagnetic driver close to the workpiece to be formed cooperates with the contour shape of the area of ​​the workpiece to be formed or the contour shape o...

Embodiment 2

[0048] Correspondingly, the present invention also proposes a heat transfer plate forming method based on the above-mentioned heat transfer plate forming device, comprising the following steps:

[0049] Step 1: Place the workpiece to be formed on the top of the mold reasonably, select a single-step electromagnetic driver according to the shape of the forming, position it and install it on the top of the workpiece to be formed, connect the same end of the single-step electromagnetic driver and the workpiece to be formed through the conductive electrode, and the other end It is connected with the power system to form a loop, and then the workpiece to be formed and the single-step electromagnetic driver are fixed by the blank holder unit.

[0050] Step 2: Charge the capacitor through the power supply system. After the capacitor is charged, discharge the single-step electromagnetic driver and the workpiece to be formed. The single-step electromagnetic driver generates a pulsed magn...

Embodiment 3

[0060] The difference between this embodiment and the first embodiment is that this embodiment adopts a single-layer multi-turn electromagnetic driver. A heat transfer plate forming device in the form of a multi-turn electromagnetic drive such as Figure 4 shown. The single-layer multi-turn electromagnetic driver 2 is composed of a single-layer multi-turn spiral coil 2-1-2, a skeleton 2-2 and a reinforcement layer 2-3, and the single-layer multi-turn spiral coil 2-1-2 is wound on the skeleton 2 On -2, the reinforcement layer 2-3 is wound around the single-layer multi-turn helical coil 2-1-2, and the reinforcement layer is used to reinforce the helical coil to prevent deformation of the helical coil. The skeleton or reinforcing layer is made of insulating material similar to epoxy resin. Under the same forming conditions, the single-layer multi-turn electromagnetic driver can provide greater electromagnetic forming force than the single-layer single-turn electromagnetic drive...

Abstract

The invention discloses a heat transfer plate forming device and forming method. The device comprises an electromagnetic driver, a mold, a power supply system and an edge pressing unit. The electromagnetic driver is located above a workpiece to be formed. The edge pressing unit is located on the edge of the workpiece to be formed. The mold is located below the workpiece to be formed. The workpieceto be formed is in series connection with the electromagnetic driver to form an electrical series loop. The power supply system provides pulse current for the series loop. The shape of the side, close to the workpiece to be formed, of the electromagnetic driver is matched with the outline shape of the area, to be formed, of the workpiece to be formed or the outline shape of an intermediate workpiece formed in the former step. The power supply system provides the pulse current for the series loop. Under the action of the pulse current, a magnetic field is generated around the workpiece to be formed and the electromagnetic driver, and electromagnetic force is generated under the combined action of the magnetic field and self electric current of the workpiece to be formed so that the workpiece to be formed is enabled to deform for multiple times to tend to be in the shape of the mold. A heat transfer plate stresses even force, and the forming accuracy of the heat transfer plate is improved.

Description

technical field [0001] The invention belongs to the related field of part forming and manufacturing, and more specifically relates to a heat transfer plate forming device and forming method. Background technique [0002] With the continuous improvement of people's requirements for comfort standards, heating methods such as radiators and air conditioners that directly heat air have been difficult to meet people's needs. Floor radiant heating, as a new type of heating method, has been widely recognized for its superiority and is popular in developed countries in Europe, America, Japan, South Korea and all over the world. It has been recognized by the world's HVAC industry as one of the most ideal and advanced heating methods. The principle is to feed circulating hot water into the heating pipe loop under the laid floor or floor tiles or directly lay heating cables to heat the floor. The heat passes through a large area of ​​the ground and mainly radiates to the space above the...
