The first upper pressing wheel 3-1-1 and the first lower pressing wheel 3-1-2 are matched with each other to press a pre-processing groove with transition chamfers at two sides on an input plate 11. Two corresponding auxiliary supporting wheels 12 are symmetrically arranged on two sides of the first lower pressing wheel 3-1-2 and used for providing support for the processed sheet material 11.

Along the conveying direction of the plate 11, the ring width of the first annular protrusion 3-1-3 (i.e. the difference between the outer diameter of the first annular protrusion 3-1-3 and the diameter of the first upper pressing wheel 3-1-1) and the depth of the first annular groove 3-1-4 in each single-groove bending unit 3-1 are gradually increased, and the width of the first annular groove 3-1-4 is gradually reduced, so that the pre-processing groove on the plate 11 is gradually pressed deep and narrowed, and the shape of the groove gradually approaches the requirement of the reinforcing rib 200.

As shown in FIG. 5, each single-groove shaping unit 3-2 comprises a first mounting seat 3-2-1, a lower limiting wheel 3-2-2, an upper limiting wheel 3-2-3 and a side pressure wheel 3-2-4 on the basis of an upper rotating shaft 8 and a lower rotating shaft 9. The upper limiting wheel 3-2-3 and the lower limiting wheel 3-2-2 are respectively fixed in the middle of the corresponding upper rotating shaft 8 and lower rotating shaft 9. The upper limiting wheels 3-2-3 are used for limiting the position of the top surface of the plate and avoiding the deformation of the top surface of the plate. The lower limiting wheel 3-2-2 is used for providing support for the bottom surface of the prefabricated groove machined in the bent part of the single groove body. The first mounting seat 3-2-1 is fixed on the frame 1 and is positioned right below the lower limiting wheel 3-2-2. The two side pinch wheels 3-2-4 are rotatably connected to the first mounting seat 3-2-1 and are respectively positioned at two sides of the bottom of the upper limiting wheel 3-2-3. In the direction from bottom to top, the axes of the two side pinch rollers 3-2-4 incline to one side far away from the upper limiting wheel 3-2-3.

The outer circumferential surface of the side pinch roller 3-2-4 comprises a squeezing surface 3-2-2 and a limiting surface 3-2-6 which are positioned on the upper side. At the contact position of the side pressure wheel 3-2-4 and the plate 11, the extrusion surface 3-2-2 is a vertical line, and the limiting surface 3-2-6 is an inclined line. The extrusion surfaces 3-2-2 of the two side pressure wheels 3-2-4 are used for keeping the positions, close to the opening, of the two side plates of the groove to be machined in a vertical posture and extruding the two side plates inwards, so that the opening is reduced; the limiting surfaces 3-2-6 of the two side pressing wheels 3-2-4 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 lower limiting wheel 3-2-2 and used for providing support for the processed sheet material 11.

Along the conveying direction of the plate 11, the distance between two lateral pressure wheels 3-2-4 in each single-groove shaping unit 3-2 is gradually reduced; the pre-machined grooves are formed by gradual deformation to finally form an upper closed part and a lower triangular part. In the single-groove body shaping part, the middle part of the circumferential surface of an upper limiting wheel 3-2-3 in a plurality of single-groove shaping units 3-2 positioned in front is integrally formed with a limiting ring; the bottom of the limiting ring extends into a pre-processing groove formed in the plate, the top of the pre-processing groove is supported from inside to outside, and the shape of the pre-processing groove is adjusted by matching with the two side pressing wheels 3-2-4. The upper limiting wheels 3-2-3 in the plurality of single-groove shaping units 3-2 positioned at the back are not provided with limiting rings, 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 shown in FIG. 6, on the basis of the upper rotating shaft 8 and the lower rotating shaft 9, each double-groove bending unit 4-1 further comprises a second upper pressing wheel 4-1-1, a second lower pressing wheel 4-1-2 and a limiting and maintaining wheel 4-1-3. The second upper pinch roller 4-1-1 is fixed in the middle of the upper rotating shaft 8. The limiting retaining wheel 4-1-3 and the two second lower pressing wheels 4-1-2 are fixed on the corresponding lower rotating shaft 9. The limiting and maintaining wheel 4-1-3 is aligned with the middle position of the two side pinch wheels 3-2-4 of the single-groove shaping unit 3-2, and the outer circumference of the limiting and maintaining wheel 4-1-3 is provided with a wheel groove. The width of the wheel groove is larger than or equal to the width of the reinforcing rib 200 processed by the single groove processing section 3; the depth of the wheel groove is equal to the height of the reinforcing bars 200 processed by the single groove processing section 3. In the working process, the bottom surfaces of the wheel grooves are in contact with the bottom of the reinforcing ribs 200, so that the supplementary power is supplied for forward conveying of the plate 11.

The two second lower pinch rollers 4-1-2 are symmetrically arranged at two sides of the limiting and maintaining wheel 4-1-3. Two second annular bulges are arranged on the outer circumferential surface of the second upper long-strip-shaped pinch roller 4-1-1; and second annular grooves are formed in the outer circumferential surfaces of the two second lower pinch rollers 4-1-2. The two second annular bulges are respectively aligned with the two second annular grooves. The bottoms of the two second annular bulges respectively extend into the tops of the two second annular grooves. Two sets of second annular bulges and second annular grooves are mutually matched, and two rectangular preprocessing grooves can be pressed on the input plate 11. The second annular groove can be formed by forming a disc-shaped workpiece; can be obtained by clamping a small-diameter disc between two large-diameter discs (a gap can be left between the large-diameter disc and the small-diameter disc, so that the width of the second annular groove can be adjusted by moving the position of the large-diameter disc).

The opposite side surfaces of the two second annular bulges are convex round table surfaces. The small diameter edge of the circular table surface is aligned with the side surface of the second annular groove close to the limit retaining wheel 4-1-3. The outer circumferential surface of the second annular bulge is located at the center position in the corresponding second annular groove. In the process of forming the pre-processing groove, the circular table top is in close contact with the plate. Therefore, the plate positioned on the inner side of the annular bulge is tightly contacted with the annular bulge, and the plate positioned on the outer side of the annular bulge is suspended. Therefore, as for the areas of the plate material on the left and right sides of the outer circumferential surface of the annular protrusion, the friction force received by the area of the plate material located on the inner side of the annular protrusion (the side close to the middle of the plate material) is greater than the friction force received by the area of the plate material located on the outer side of the annular protrusion; so that the material required for forming the pre-processing groove on the plate is mainly provided by inwards retracting the edge of the plate; the phenomenon that the middle position of the plate is pulled towards two sides due to the fact that two preprocessing grooves are formed at the same time is avoided, and the formed reinforcing rib 200 located in the middle is prevented from being damaged.

Along the conveying direction of the plate 11, the annular width of the second annular bulge (namely the difference between the outer diameter of the second annular bulge and the diameter of the second upper pressing wheel 4-1-1) in each double-groove bending unit 4-1 and the depth of the second annular groove are gradually increased, the width of the second annular groove is gradually reduced, and the distance between the second annular grooves of the two second lower pressing wheels 4-1-2 is gradually reduced, so that the preprocessed groove on the plate 11 is gradually pressed deeply and narrowed, and the shape of the groove is gradually close to the requirement of the reinforcing rib 200; and through inwards being close to gradually with two groove of preprocessing in the forming process for on the panel in the groove of preprocessing lean on the partial material of panel central point department can form the partly of the required material of the groove deepening of preprocessing, further avoid two groove of preprocessing simultaneously the shaping to lead to the condition that panel intermediate position is dragged to both sides to appear.

The two shaping subunits are respectively aligned with the two second lower pressing wheels 4-1-2 in the last double-groove bending unit 4-1.

In all the shaping subunits used for processing the same reinforcing rib, each side pinch roller 4-1-4 positioned at the inner side of the upper limiting wheel 4-1-3 is aligned along the conveying direction of the plate; thereby avoiding the pulling of the middle position of the plate in the process of closing the opening of the prefabricated groove; along the conveying direction of the plate 11, the distance between two side press wheels 3-2-4 in each shaping subunit for processing the same reinforcing rib is gradually reduced; the pre-machined grooves are formed by gradual deformation to finally form an upper closed part and a lower triangular part.

Thereby realizing synchronous reverse rotation of the first rolling wheel 7-1 and the second rolling wheel 7-2. The middle positions of the first and second rollers 7-1 and 7-2 are aligned with the top of the output position of the corresponding reinforcing bars 200 such that the reinforcing bars 200 pass between the first and second rollers 7-1 and 7-2 and are pressed by the first and second rollers 7-1 and 7-2, thereby improving the shape stability of the reinforcing bars 200.

A pressurizing bulge 7-3 is arranged on the outer circumferential surface of the first grinding wheel 7-1; an abdicating notch 7-4 is arranged on the outer circumferential surface of the second grinding wheel 7-2. The pressurizing bulge 7-3 corresponds to the position of the abdicating notch 7-4. When the first rolling wheel 7-1 and the second rolling wheel 7-2 rotate for one circle, the pressurizing protrusion 7-3 and the abdicating notch 7-4 are aligned once, and a side groove is extruded at the top of the reinforcing rib 200, so that the tops of two side plates of the reinforcing rib 200 are tightly combined together, and the structural stability of the reinforcing rib 200 is improved.

On the basis, the first rolling wheel 7-1 and the second rolling wheel 7-2 can rotate under the friction force of the forward movement of the reinforcing ribs 200, and can also be driven by a separate motor to rotate so as to provide auxiliary power for the forward conveying of the reinforcing ribs 200.

The upper press rolls 5-1-1 are fixed in the middle of the corresponding upper rotating shafts 8. Two downward turning supporting wheels 5-1-3 and three guiding conveying wheels 5-1-2 are fixed on a lower rotating shaft 9. The positions of the three guide conveying wheels 5-1-2 correspond to the three reinforcing ribs 200 processed on the plate 11 respectively. The outer circumference of each guide conveying wheel 5-1-2 is provided with a wheel groove. The width of the wheel groove is greater than or equal to the width of the reinforcing rib 200; the depth of the wheel groove of the partial guide conveying wheel 5-1-2 corresponds to the height of the reinforcing ribs 200, so as to provide auxiliary power for forward conveying of the plate 11. For the three reinforcing ribs 200, the number of the guide conveying wheels 5-1-2 capable of providing auxiliary power is consistent, so that the three reinforcing ribs 200 can obtain uniform conveying force, and the plate 11 is prevented from being deformed or damaged due to excessive shearing force.

The two downward turning supporting wheels 5-1-3 are respectively positioned at the opposite sides of the three guiding conveying wheels 5-1-2 and are respectively close to the two side edges of the plate 11 output by the double-groove processing section 4.

The downward turning supporting wheels 5-1-3 are matched with the corresponding conical pressing wheels 5-1-4, and the part of the edge of the plate 11, which exceeds the outer sides of the downward turning supporting wheels 5-1-3, is bent downwards.

The distance between the two conical pressing wheels 5-1-4 in the inward turning unit 5-2 is smaller than the distance between the two conical pressing wheels 5-1-4 in the downward turning unit 5-1, so that two different positions of the edge of the plate 11 can be turned, and a vertical downward turning edge and a horizontal inward turning edge are formed. The two inversion units 5-2 located at the extreme ends have a structure different from the remaining inversion units 5-2.

On the basis of the rest of the inward turning units 5-2, the two inward turning units 5-2 positioned at the tail end are not provided with the tapered pinch rollers 5-1-4, and are additionally provided with two side shaping wheels 5-2-1; the outer side surface of the downward turning supporting wheel 5-1-3 is provided with an annular limiting step; this spacing step is used for finalizing the design to turn over the turn-ups in the edge of turn-ups upwards, further reduce 11 marginal fish tail users' of panel possibility.

In the working process, the two side shaping wheels 5-2-1 respectively support the flanges formed on the two sides of the plate 11, and the convex parts on the side shaping wheels 5-2-1 enable the flanges on the two sides of the plate 11 to be concave and deformed, so that the space complexity of the flanges is improved, and further the bending strength of the flanges in different directions is improved.

Along the conveying direction of the plate 11, the taper of the tapered pressing wheel 5-1-4 in each downward turning unit 5-1 is gradually increased, so that the edges of the two sides of the plate 11 are continuously turned downwards in a gradual deformation mode until two vertical turned edges are formed.

Along the conveying direction of the plate 11, the taper of the tapered pressing wheels 5-1-4 in each inward turning unit 5-2 is gradually increased, so that the edges of the two sides of the plate 11 are continuously turned downwards in a gradual deformation mode until two new vertical turned edges are formed. At this time, the vertical flanging output by the downward-flanging part forms an inward horizontal flanging.
