As shown in fig. 2, the introduction section 2 includes a support roller 2-1, a guide plate 2-2, a guide bar 2-3, and a width adjustment mechanism 2-4. A plurality of supporting rollers 2-1 which are arranged along the length direction of the frame 1 at equal intervals in sequence are all rotatably connected with the input end of the frame 1. Two guide rods 2-3 with axes parallel to the width direction of the frame 1 are fixed at the input end of the frame 1. The two guide plates 2-2 are connected with the two guide rods 2-3 in a sliding manner through slide blocks. A yielding hole or a yielding groove is formed at the joint of the guide plate 2-2 and the supporting roller 2-1 so as to avoid interference between the guide plate 2-2 and the supporting roller 2-1. The two guide plates 2-2 adjust the position of the guide plates in the width direction of the frame 1 through corresponding width adjusting mechanisms 2-4 respectively. The width adjustment mechanism 2-4 includes a lead screw and a nut. The lead screw with the axis parallel to the width direction of the frame 1 is connected to the frame 1 through a bearing. The nuts are fixed on the corresponding guide plates 2-2. The screw rod is rotationally connected with the nut. The guide plate 2-2 is adjusted in position laterally by rotating the lead screw. The distance between the two guide plates 2-2 is adjusted to be consistent with the width of the input coiled sheet material 5; the position of the two guide plates 2-2 can be adjusted to transversely adjust the input position of the coiled sheet material 5, so that the position of the processed reinforcing rib can be adjusted.

The outer circumferential surface of the side pinch roller 4-1-4 comprises a squeezing surface 4-1-5 and a limiting surface 4-1-6 which are positioned on the upper side. At the contact position of the side pressure wheel 4-1-4 and the plate 5, the extrusion surface 4-1-5 is a vertical line, and the limiting surface 4-1-6 is an inclined line. The extrusion surfaces 4-1-5 of the two side pressure wheels 4-1-4 are used for keeping the positions, close to the opening, of the two side plates of the prefabricated groove in a vertical posture and extruding inwards, so that the opening is reduced; the limiting surfaces 4-1-6 of the two side pressing wheels 4-1-4 are used for guiding the two side plates of the prefabricated groove to the inclined posture away from the position of the opening, so that the transition between the unchanged bottom surface width of the prefabricated groove and the gradually reduced opening width is realized. The two auxiliary supporting wheels are respectively positioned at two sides of the second limiting wheel 4-1-2 and used for providing support for the processed plate 5.

Along the conveying direction of the plate 5, the distance between two lateral press wheels 4-1-4 in each reinforcing rib shaping unit 4-1 is gradually reduced; the pre-machined grooves are formed into an upper closed part and a lower triangular part finally by means of gradual deformation.

Six reinforcing rib shaping units 4-1; limiting rings 4-1-7 are integrally formed in the middle of the circumferential surface of the first limiting wheels 4-1-3 of the first three reinforcing rib shaping units 4-1 in the conveying direction of the plate 5; the bottom of the limiting ring 4-1-7 extends into a pre-processing groove formed on the plate, supports are provided for the opening of the pre-processing groove from inside to outside, and the shape of the pre-processing groove is adjusted by matching with the two side pressure wheels 4-1-4. The width of each limit ring is gradually reduced along the conveying direction of the plate (6). The first limiting wheels 4-1-3 in the last three reinforcing rib shaping units 4-1 along the conveying direction of the plate 5 are not provided with limiting circular rings 4-1-7, because the tops of the two side surfaces of the preprocessed groove are very close to each other at the moment and do not need to be supported from inside to outside.

As an optional technical scheme, a cutting device 6 is arranged at the tail end of the reinforcing rib forming mechanism, and the cutting device 6 cuts the reinforcing rib-provided plate with the specified length through the lifting motion of the cutter.

The working principle of the utility model is as follows:

one end of the coiled metal sheet is fed into the lead-in section 2 in a flat state; the plate material enters the reinforcing rib forming mechanism under the guidance of the leading-in section 2. In the reinforcing rib forming mechanism, a plate firstly passes through each groove body bending unit 3-1 in sequence; each groove body bending unit 3-1 forms a preprocessing groove on the plate through the matching of the annular bulge and the annular groove, and the preprocessing groove is gradually deepened and narrowed; each reinforcing rib shaping unit 4-1 extrudes the opening of the preprocessing groove through a side pressure wheel, so that the opening of the preprocessing groove is gradually closed to form a reinforcing rib with a triangular groove body at the lower part and closed sections at two sides at the upper part. The resulting reinforcing ribs are located on the bottom surface of the panel.

By arranging a plurality of reinforcing rib forming mechanisms connected in series behind the introduction section 2 (the processing positions are staggered along the width direction of the plate), a plurality of reinforcing ribs arranged in parallel along the length direction of the plate can be formed on the metal plate. Due to the shape characteristics of the reinforcing ribs, the bending resistance of the plate in the length direction of the plate is greatly improved, so that the bearing capacity of the plate is obviously improved; in addition, the top surface of the sheet material remains substantially flat due to the closed top of the ribs, and the top surface of the sheet material after the ribs are formed can be used to carry goods, such as a shelf divider.

Example 2

This example differs from example 1 in that: the first rotating shaft is positioned right below the second rotating shaft; the reinforcing ribs processed by the embodiment are positioned on the top surface of the plate.
