Description

Continuous roll forming device with multiple groups of rollers

Technical Field

The utility model relates to a roll-in, roll bending forming technology, concretely relates to continuous roll forming device of multiunit roller.

Background

In 2017, a C919 large passenger plane flies successfully for the first time, and the technical breakthrough of the domestic middle-range trunk passenger plane in China is realized. Since 10 horses in shipping, the large-scale passenger aircraft in China falls, crashes and bumps all the way, large airplanes and civil aviation engines become permanent hurts in the heart of Chinese people, and after 30 years of arduous and hardship, C919 flies over the sky of China all the time, so that Chinese people have own trunk passenger aircraft. The avionics, flight control and engines which are the most core of the aircraft are all launched by the middle aviation industry or commercial, and although the engines of the U.S. GE are used in the current stage C919, the engines of the national Yangtze river 1000A are expected to be changed after 2020. At present, some parts of engines produced by GE company in America are processed by manufacturers in China due to the difficulty of manufacturing process. Aiming at an engine produced by GE (general electric) company in the United states, a matching part honeycomb is difficult and complicated in machining process, the production efficiency of the engine is seriously influenced, and the production delivery schedule is delayed.

Disclosure of Invention

For solving above-mentioned production efficiency and product quality problem, the utility model provides a multiunit roller is rolling forming device in succession.

The utility model adopts the technical proposal that: the multi-group roller continuous roll forming device comprises a plurality of roller groups which are horizontally arranged; each roller set comprises an upper roller, a lower roller and a support, and the upper roller and the lower roller are arranged on the supports on the two sides;

the rolling surface of the upper roller of the plurality of roller sets gradually becomes wider from the feeding end.

Preferably, the cross section of the support is L-shaped, and a first mounting hole and a second mounting hole are sequentially formed in the vertical side of the support from top to bottom; the first mounting hole is used for mounting an upper roller; the second mounting hole is used for mounting the lower roller.

Preferably, the horizontal edge of the support is provided with a fixing hole.

Preferably, the lower roller is provided with annular baffles on two sides.

Compared with the prior art, the beneficial effects of the utility model are that: the production efficiency is high, and the required equipment and the number of workers are small; the component with quite complex section shape can be manufactured, and the requirement of structural design can be met to the maximum extent; can obtain the workpieces with various shapes and high surface processing quality (ensuring the surface quality of the belt material); the forming roll which is a main tool for roll forming has long service life, simple manufacture and low cost; the material utilization rate is high.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Reference is made to fig. 1-4;

the multi-group roller continuous roll forming device comprises a plurality of roller groups which are horizontally arranged; each roller set comprises an upper roller 1, a lower roller 2 and a support 3, the cross section of the support is L-shaped, and a first mounting hole 310 and a second mounting hole 320 are sequentially arranged on the vertical side of the support from top to bottom; the first mounting hole 310 is used for mounting the upper roll 1; the second mounting hole 320 is used for mounting the lower roller 2;

the rolling surface of the upper roller 1 of the plurality of roller sets gradually widens from the feeding end.

Further, the horizontal edge of the support 3 is provided with 2 fixing holes 330, and the number of the fixing holes 330 is 2, so that the fixing is facilitated.

Further, the lower roller 2 is provided with ring-shaped baffles 210 on both sides, and the ring-shaped baffles 210 can ensure that the material moves according to a set direction.

The working principle is as follows: the rolling process is a non-chip process in which some form of rolling tool applies some pressure to the surface of the material. At normal temperature, the plastic deformation of metal is utilized to flatten the microscopic unevenness of the surface of the material so as to change the surface structure, mechanical characteristics, shape and size. Therefore, the device can achieve two purposes of finishing and strengthening at the same time. The sizes of the lower rollers 2 of all the roller sets are the same, and the sizes of the upper rollers 1 are gradually changed (as shown in figure 4). Under the action of external force, the material enters from the first group of rollers, sequentially passes through the second, third, fourth and fifth groups of rollers, and finally comes out from the six groups of rollers (the last group) (figure 1), in the process, the material generates local micro plastic deformation on the surface layer under the action of the mutual action force of the roller groups, the section shape is gradually changed along with the change of the size of the upper roller of each group of rollers, and then the plastic processing for thinning the material is obtained as shown in figure 5. Since the roll processing is a processing method using rolling with a roller, the diameter of the material changes before and after the processing (the inner diameter increases and the outer diameter decreases). In order to be able to process within dimensional tolerances, the dimensions of the preceding steps should be determined taking this variation into account. The change in diameter is related to the material, hardness, and rolling amount of the material, and therefore the dimensions are determined after 2 to 3 trial works are initially performed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
