Process for one-piece automotive assembly frame

The invention relates to a process for integrally forming a vehicle assembly frame, in particular to a process for improving the production performance of the vehicle group device.

The car is equipped with a vehicle assembly frame to provide a bumper assembly. Since the bumper is curved, the vehicle assembly frame is also curved. At present, the assembly process of the vehicle assembly frame divides the vehicle assembly frame into several sections and The assembly unit is formed, and the assembly units are processed first, and the operator assembles the assembled assembly units by manual welding and assembles the vehicle assembly frame.

However, the assembly units are processed and stacked one by one in the factory, which causes inconvenience in the management of raw material storage and management, and the assembly units of different sections are used for welding, which causes difficulty in planning the integral moving line and time-consuming work. In addition, the assembled structure of the vehicle assembly frame assembled by the assembled process method is not strong enough to meet the safety requirements.

The main object of the present invention is to provide a process for integrally forming a vehicle assembly frame, thereby improving the difficulty of inconvenient storage and management of raw materials in the current assembly process.

In order to achieve the foregoing object, the process of the one-piece molding vehicle assembly frame of the present invention comprises: a rolling step, the metal plate to be processed is conveyed to a rolling device, and gradually formed by an array roller group on the rolling device. The roll forming is a continuous semi-finished product for a vehicle assembly; in a welding step, the continuous semi-finished product of the vehicle assembly is then passed through a welding machine, and the semi-finished product of the vehicle assembly frame is welded by the welding machine to fix the cross-sectional shape; In a cutting step, the welded fixed semi-finished product of the vehicle assembly frame is bent upward by the guidance of a guide wheel, and the curved assembly of the vehicle assembly frame is cut by a cutting machine to form a vehicle assembly frame.

According to the above, the rolling step, the welding step and the cutting step of the process of the integrally formed vehicle assembly frame adopt a one-stop production line, which makes the moving line planning smooth, and facilitates the management of raw materials and saves the original materials. The storage space, and the metal plate is gradually rolled and shaped by the rolling device, and then welded to fix the cross-sectional shape, so that the assembled vehicle frame is an integrally formed component, and the structure of the vehicle assembly frame can be made. Increased strength and safety.

Referring to FIG. 1, a preferred embodiment of the process for assembling an integrally formed vehicle assembly according to the present invention includes a rolling step, a welding step and a cutting step.

In the rolling step, a metal coil is placed on a roller seat, and the free end of the metal coil enters the conveying track and is conveyed to a rolling device, and the metal plate to be processed provided by the metal coil sequentially passes through the rolling device. The upper array roller group is formed by progressively rolling the metal plates to be processed through the roller sets to form a continuous semi-finished assembly for a vehicle, wherein the metal plates to be processed pass the roller sets and gradually increase the rollers. The amount of deformation of the pressure, the two sides of the metal plate are first bent upwards and then bent inward and downward to form a semi-finished product assembly frame.

The continuous vehicular assembly frame semi-finished product which is roll-formed by the rolling step is then passed through a welding machine which welds the two sides of the bent metal plate to fix the cross-sectional shape of the semi-finished product of the vehicular assembly frame.

In the cutting step, the welded fixed vehicular assembly semi-finished product is bent upward by the guidance of a guide wheel, wherein the top of the guide wheel is higher than the top of the roller below the roller set, and A cutting machine cuts a curved semi-finished vehicle assembly frame to form a vehicle assembly frame.

In the above, when the metal plate to be processed is conveyed to the rolling device, a flattening assembly is first passed to level the metal plate to be processed, and then the rolling step is performed after leveling.

Referring to FIG. 2 and FIG. 3, the rolling step includes a bottom plate forming stage, a side plate forming stage, and a side plate portion facing inward folding stage, and further including between the bottom plate forming stage and the side plate forming stage. In the forming stage of a top plate portion, referring to FIG. 4 and FIG. 5, the deformation amount of the bottom plate portion 11 of the vehicle assembly frame 10 is rolled out at the middle portion of the metal plate to be processed in the bottom plate forming stage. The roller set is rolled on both sides of the metal plate to be processed in the forming stage of the top plate portion, and the deformation amount of the top plate portion 12 of the assembly frame 10 for the vehicle is rolled, and part of the roller set gradually increases the amount of deformation of the bent portion in the forming stage of the side plate portion. The side plate portion 13 of the vehicular assembly frame 10 is formed, and part of the roller group folds the side plate portion 13 inwardly to form a top plate portion 12 facing the bottom plate portion 11 to form a semi-finished product for a vehicle assembly that is not welded and fixed.

In summary, the process of the one-piece vehicular assembly frame provides the metal sheet of the metal coil through the rolling step, the welding step and the cutting step in sequence, thereby manufacturing the integrally formed vehicular assembly frame 10, rolling The step, the welding step and the cutting step adopt a one-stop production line to improve the smoothness of the moving line planning, and the raw materials of the metal sheet to be processed enter the rolling step, and then pass through the welding step to the cutting step to form a vehicle assembly. The finished product of the frame 10, so that the raw material that needs to be pre-stacked is not generated by the rolling step, the welding step and the cutting step, so the process of the integrally formed vehicle assembly frame 10 can improve the convenience of raw material management and save raw materials. The required storage space and the assembled vehicle assembly frame 10 are integrally formed members, which can improve the structural strength and safety of the vehicle assembly frame 10.
