Hot stamping production line

Abstract

The invention discloses a hot stamping and forming production line. The hot stamping and forming production line comprises a feeding robot, a first lifting table, a heating furnace, a second lifting table, a conveying robot, a press and a discharging robot which are arranged sequentially, wherein multiple layers of rolling tables are arranged in a hearth of the heating furnace; each of the first lifting table and the second lifting table comprises a conveying platform and a lifting device for driving the conveying platform to lift, and the lifting device and the conveying platform are matched to feed materials to or discharge materials from the rolling tables layer by layer. Through arrangement of the first lifting table and the second lifting table, the rolling table is not required to perform continuous feeding in a single direction, that is, the length of the hearth of the heating furnace is much shorter than that in the prior art, and the occupation area of the production line is reduced greatly. The manipulators are not required to extend into a furnace cavity to grab blanks, the materials in the furnace cavity cannot be bumped against the manipulator and damaged, so that expensive and vulnerable metal materials are not required to be selected, and the production cost is saved; meanwhile, the heat resistance requirement for each manipulator of each robot is low, and the production cost is further saved.

Description

technical field [0001] The invention relates to a hot stamping forming production line. Background technique [0002] The current hot stamping production line is divided into continuous roller hearth heating furnace production line and multi-layer box type heating furnace production line. Among them, in the continuous roller bottom heating furnace production line, the robot sends the heated billet to the rolling inlet end of the heating furnace, and the heated billet is continuously fed and heated by the unidirectional rolling roller in the heating furnace until it is sent to the outlet end of the heating furnace. Then it is picked up by the robot and sent to the press. Since the billet needs to be continuously fed into the press while being heated and kept warm, and the heating and holding time needs at least 300 seconds, this requires the transfer time of the billet from the inlet end to the outlet end in the furnace cavity to be 300 seconds, and it is also necessary to e...

Problems solved by technology

Since the billet needs to be continuously fed into the press while being heated and kept warm, and the heating and holding time needs at least 300 seconds, this requires the transfer time of the billet from the inlet end to the outlet end in the furnace cavity to be 300 seconds, and it is also necessary to ensure that the heating furnace It can support the production volume of the press, that is, to ensure a certain production cycle. Therefore, the furnace of the heating furnace of this kind of production line is very long, usually tens of meters, and covers a large area.

[0003] The multi-layer box-type heating furnace production line relies on the picker of the same robot to reach into the furnace of each layer of the multi-layer box-type heating furnace, and puts the heated billet from the same furnace door of a certain layer for heating and heat preservation. After picking up and taking out the heated billet, the robot in this way is occupied for a long time, resulting in low production efficiency. At the same time, it takes much longer for the robot end picker / manipulator to pick up and deliver the billet than the billet sent by the roller, which further reduces the production efficiency. decline

Moreover, the end picker of the manipulator must be able to withstand the high temperature in the furnace cavity, so it is necessary to use materials that are resistant to repeated temperature changes, and the cost is high
