Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to a rolling and pressing process device before welding an all-aluminum water chamber and a main sheet. Background Art

[0002] The car radiator is an indispensable and important part in the engine cooling system. As the country advocates lighter and lighter cars, the volume inside the car is also getting smaller and smaller, so more and more radiators are made of all-aluminum. However, if the water chamber of the all-aluminum radiator is also made of aluminum, the connection with the main core piece is welded or snap-fitted. The reliability of the snap-fitted product is poor and cannot pass a series of test requirements such as pulse. Therefore, most of them now use the form of welding the aluminum water chamber and the main piece. However, during the welding process, since both the main piece and the water chamber are stamped parts, there are parts deformation, rebound after stamping, and the tolerance cannot be too small (if it is too small, the water chamber cannot be put into the main piece).

[0003] As disclosed in Chinese patent application CN201910222245.1, the previous technical solution is to achieve the rolling and edge pressing operation through a rolling wheel. However, since the rolling wheel performs continuous rolling motion in one direction when working, an opposite stress will be formed on both sides of the rolling wheel when the rolling wheel pushes the main sheet toward the center for extrusion. When the rolling wheel continues to extrude and compact in one direction, the stress in front of the rolling wheel will accumulate, and certain undulating wrinkles will appear at the rear due to the release of reverse stress, which will lead to uneven gaps after compaction and bring quality problems to subsequent welding. Therefore, how to improve the qualified rate of welding. Utility Model Content

[0027] Among them, the rolling mechanism is provided with a combined rolling cutter at one end close to the core bracket 8, including a pre-pressing rolling cutter and a final pressing rolling cutter, and the two pre-pressing rolling cutters and the final pressing rolling cutter are arranged in parallel along the length direction of the core. Figure 3 As shown in FIG. 1 , the pre-pressing rolling tool is a roller with a toothed edge; Figure 4 As shown, the final pressing and rolling tool is a roller with a smooth edge, and the pre-pressing and rolling tool and the final pressing and rolling tool are rotatably connected with the rolling mechanism. The main sheet 7 is pushed into the edge of the water chamber 6 by combining the rollers and rolling presses, so that the uniform gap between the main sheet 7 and the water chamber 6 after the core body is welded becomes smaller, thereby improving the qualified rate of welding.

[0028] The product water chamber 6 and the core main sheet 7 are as follows Figure 2After being assembled as shown, it is placed on the core bracket 8; to ensure the positioning of the product, the cylinder above positions the water chamber 6, so that it is positioned and tightly attached in the vertical direction, and then the main pieces 7 on both sides are pushed toward the horizontal center direction (positive and negative directions of X). During the horizontal advancement of the product, the pressing cylinders on the left and right sides are used to push the oblique blocks in the middle to push the left and right combined rollers, so that the main piece can be correctly and completely attached to the water chamber 6 in the horizontal direction 0-01MM. At the same time, the servo motors on the left and right drive the entire rolling bracket to roll and press the main piece 7 front and back, so that the entire long strip of the main piece 7 is attached to the water chamber 6, making it easier to weld during welding, without defects such as pores, leaking welding, false welding, shrinkage holes, etc. The quality and size of the product after welding after the completion of the bonding are completely in line with the design requirements of the pattern.
