Overall assembly method of press welder

Abstract

The invention discloses a overall assembly method of a press welder, and relates to the technical field of press welders. The overall assembly method comprises the following steps of S1, removing an original steel seat of equipment, removing all useless parts of a middle movable seat so as to reduce the overall height of the equipment, and achieving hoisting and overhaul of parts such as oil cylinders on the top part of the machine by using a travelling crane; and S2, redesigning a machine head portion, removing an original L-shaped copper bar connection, changing the copper bar into a copperplate, adjusting the connection mode of the copper plate, and enabling the upper surface of the machine head to be a complete plane after being assembled. According to the method, an automobile craneis not needed every overhaul, the overhaul and maintenance cost is reduced, the contact area and the connection reliability are increased, the copper bar is easy to install and replace, the internal stress generated during an installation process is prevented, the overall fixing reliability of the equipment is improved, and meanwhile, the possibility of spark striking is further reduced, the structure is simple, the leakage point is small, the weight and the purchase cost are reduced, the utilization rate of spare parts is improved, and the replacement time of electrodes is reduced.

Description

technical field [0001] The invention relates to the technical field of pressure welding machines, in particular to an overall assembly method for pressure welding machines. Background technique [0002] Pressure welding machine is a kind of welding platform mechanical equipment, which mainly adopts floating device, so that the welding pressure does not directly act on the turntable, so as to achieve precise positioning of hot-press welding and realize precision welding. [0003] The assembly of the existing pressure welding machine has the following defects: 1. The overall height is high, it is inconvenient to check and maintain, and the equipment shakes when it is working; 10 L-shaped copper bars are used to connect the positive and negative electrodes to the machine head, which is not easy to locate and install and the copper bars are more damaged; 4. The fixed height of the transformer cannot be adjusted, resulting in poor installation of the copper bars and poor fixation...

[0003] The assembly of the existing pressure welding machine has the following defects: 1. The overall height is high, it is inconvenient to check and maintain, and the equipment shakes when it is working; 10 L-shaped copper bars are used to connect the positive and negative electrodes to the machine head, which is not easy to locate and install and the copper bars are more damaged; 4. The fixed height of the transformer cannot be adjusted, resulting in poor installation of the copper bars and poor fixation of the transformer, and vibration during welding 5. At present, three oil cylinders are used, and there are many joints and leaks; 6. The electrodes are heavy and difficult to replace, and the cost of spare parts is high and the utilization rate is low. For this reason, we propose a pressure welding machine. overall assembly method
