System device and method for fast replacement of roller carriers in automotive strip parts rolling line

Abstract

The invention provides a system device and a method for the fast replacement of roller carriers in an automotive strip parts rolling line. The device comprises a shelf and a holding table. A trolley for transferring roller carriers and capable of horizontally moving along a passage is disposed in the passage formed between the rolling line and the shelf. Small roller components are disposed on a frame of the rolling line, a table plate of the trolley and the holding table in an arranged manner. Each small roller component comprises mounting bars and a plurality of small rollers mounted on the mounting bars, wherein the small rollers are arranged on the mounting bars at proper intervals and the mounted small rollers are higher than the mounting bars. During replacement of roller carriers, the roller carriers on the original frame are transferred with the trolley in a manner of rolling on the small roller components and are moved to the vacant holding table of the shelf, and standby roller carriers on the shelf are transferred to the frame through the trolley.

Description

technical field [0001] The invention relates to a system device and method for quickly replacing a roller frame in a rolling production line. Background technique [0002] At present, the manufacturing of automobile water cutting, sealing strips and door frames all adopt rolling processing. Rolling production line such as figure 1 As shown, the rolling process is a non-cutting continuous processing of the metal strip as the raw material, so that the metal strip passes through a plurality of roller groups composed of upper and lower rollers. The final shape of the product becomes the set cross-sectional shape, and each product needs to be equipped with multiple roller sets; multiple roller sets of the rolling production line are installed on the roller frame, such as figure 2 , image 3 As shown, generally 2 to 4 sets of rollers are installed on each roller frame. During installation, the roller frames equipped with roller groups are arranged in sequence and installed on ...

Problems solved by technology

Rolling production line such as figure 1 As shown, the rolling process is a non-cutting continuous processing of the metal strip as the raw material, so that the metal strip passes through a plurality of roller groups composed of upper and lower rollers. The final shape of the product becomes the set cross-sectional shape, and each product needs to be equipped with multiple roller sets; multiple roller sets of the rolling production line are installed on the roller frame, such as figure 2 , image 3 As shown, generally 2 to 4 sets of rollers are installed on each roller frame. During installation, the roller frames equipped with roller groups are arranged in sequence and installed on the rack of the rolling production line for shelving the roller frames. The shelving rack used to store the spare roller frame. When the rolling production line needs to change the product, the roller set is replaced together with the roller frame. It is only necessary to disassemble the roller frame equipped with the previous product-specific roller set on the rolling production line. Put it on the shelf, and then install the roller frame with the special roller group for the next product on the shelf to the rolling production line in turn; for this process, the prior art generally adopts the traditional hoisting method based on driving. This traditional hoisting method is time-consuming, laborious and inefficient. It usually takes 3 to 4 skilled workers and 2 to 3 working days to complete, and the installation accuracy and safety are difficult to guarantee. After installation, it takes a long time to debug, and the material waste during commissioning is serious. , high operating requirements for installation and commissioning personnel
