Description

Technical Field

[0001] The invention belongs to the technical field of bending machines, and specifically discloses a bending machine for shipbuilding. Background Art

[0002] A bending machine, as the name implies, is a machine that can bend a target object. It can effectively bend the target object according to people's needs. The bending machine is generally composed of a support plate, a workbench and a clamping plate. Since the bending machine generally adopts electromagnetic force clamping, the target object can be made into a variety of workpiece requirements, and it is also very easy to operate. Bending machines are generally divided into manual bending machines, hydraulic bending machines and CNC bending machines. Hydraulic bending machines are usually very common in shipbuilding and are one of the indispensable machines in shipbuilding. In the past, bending machines for shipbuilding had high quality requirements for the strength, pressure resistance and other technical indicators of the internal steel plates of ships. Ships often used steel plates with higher strength. When bending the steel plates, pressure was often applied to the steel plates to form the steel plates into a specified shape. Due to the deformation between the steel plates, the internal structure of the steel plates would change, which would affect the quality of the steel plates. Therefore, the steel plates needed to be heated. The existing method for heating the steel plates is to heat the steel plates and then put them on the bending machine to bend them. Putting the steel plates on the bending machine will cause the temperature of the steel plates to drop, which will cause the temperature of the steel plates to drop below the critical point, which will result in the failure to perform a good bending process on the steel plates. At the same time, when the steel plates are pressed down, the steel plates will warp up, resulting in poor bending. When one end of the steel plate is bent, the other end is generally fixed manually, which results in slow processing efficiency and high labor costs. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: The water is heated by a heater, and the liquid is made to pass through the positive guide plate and the reverse guide plate. At the same time, the gaps on the side of multiple groups of positive guide plates close to the connecting pipe are large, and the gaps on the side of multiple groups of reverse guide plates close to the copper bin are large, and all the gaps are funnel-shaped, so that the purpose of liquid eruption contacting the copper bin for heating and the heated liquid erupting again after being heated can be achieved, so that the liquid contacts multiple groups of copper bins for rapid heating.

[0014] When the water in the heater boils, high-temperature steam is generated, and the steam flows upward.

[0016] Pull the adjusting rod to slide in the support, and make the limiting rod drive the pressing rod to move through the slide, and at the same time the control plate drives the slide rail to slide in the inner side of the linkage frame, so that the contact point between the pressing rod and the steel plate can be changed, so as to adapt to pressing steel plates of different sizes.

[0017] The liquid is directly heated by water in the copper bin, and when the liquid flows to the upper part of the control bin, the water is heated again by water vapor, so that the water heating can be fully utilized and the liquid can be kept at a higher temperature. The lower pressure rod automatically increases the force to press the steel plate with higher temperature to avoid burns to workers fixing the steel plate. At the same time, the steel plate can be effectively bent when heated to avoid the quality of the steel plate being affected by the bending. BRIEF DESCRIPTION OF THE DRAWINGS
