Background
The coiled plate material has the advantages of convenient transportation and capability of cutting out different lengths according to requirements; thus being widely applied to the production of various devices; however, in order to facilitate winding, the thickness of the rolled sheet tends to be thin, and the bending resistance is poor; further, the rolled plate is easy to bend along the length direction after being flattened, so that the product taking the rolled plate as the raw material often has the defect of weaker loading capacity and shock resistance. In the prior art, the problem is mostly overcome by welding reinforcing ribs on a coiled plate; however, the welding process is difficult to realize high automation, and the plates with different lengths are required to be prepared with reinforcing ribs with different lengths in advance, so that the production cost is greatly increased; therefore, it is necessary to design a processing apparatus capable of forming a reinforcing rib structure from the material of the rolled sheet itself.

According to the invention, two reinforcing ribs can be processed on the plate at the same time, and the processing processes of the two reinforcing ribs are not mutually interfered; the invention sets the opposite sides of two annular bulges in the double-groove synchronous bending section as a round table surface, so that the plate positioned at the inner side of the annular bulge is tightly contacted with the annular bulge in the processing process, and the plate positioned at the outer side of the annular bulge is suspended; therefore, the friction force applied to the plate area located inside the annular protrusion is greater than the friction force applied to the plate area located outside the annular protrusion; the friction force difference enables the material required for forming the pre-processing groove on the plate to be provided mainly by inward shrinkage at the edge of the plate; the situation that the two pre-processing grooves are simultaneously formed to cause the middle position of the plate to be pulled to two sides to cause the damage of the plate is avoided.

According to the invention, the axes of the side pressing wheels are obliquely arranged, and the outer circumferential surfaces of the side pressing wheels are divided into the extrusion surfaces and the limiting surfaces, so that the reinforcing ribs automatically form a triangular groove body at the lower part and a stable structure with two side plates closed at the upper part in the opening closing process, and the bending resistance of the metal plate along the length direction is greatly improved.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and 2, a dual-stiffener synchronous processing device for improving the carrying capacity of a metal plate is used for synchronously processing two symmetrical stiffeners on an unfolded coiled plate material so as to improve the bending resistance and the cargo carrying capacity of the thin plate. The double-reinforcing-rib synchronous processing equipment comprises a frame 1, and a leading-in section 2, a double-groove synchronous bending section 3, a double-reinforcing-rib synchronous shaping section 4 and a reinforcing-rib reinforcing mechanism 5 which are arranged on the frame 1 and are connected in sequence. The leading-in section 2 is used for accurately feeding the coiled sheet material 6 into the double-groove synchronous bending section 3.
As shown in fig. 3 and 4, the double-groove synchronous bending section 3 includes a plurality of double-groove bending units 3-1 arranged at equal intervals in sequence; the double-reinforcing-rib synchronous shaping section 4 comprises a plurality of double-reinforcing-rib shaping units 4-1 which are arranged at equal intervals in sequence. Each double-groove bending unit 3-1 is used for synchronously processing two symmetrical pre-processing grooves on two sides of the middle position of the plate, and synchronously enabling the two pre-processing grooves to gradually deepen and narrow. Each double-reinforcing-rib shaping unit 4-1 is used for gradually narrowing the openings of the two pre-processing grooves until the openings are closed, so that reinforcing ribs with triangular groove bodies at the lower parts and double-side-plate closed structures at the upper parts are formed. The reinforcing rib in the shape has excellent bending resistance.
As shown in fig. 5, the reinforcing bar reinforcing mechanism 5 includes two grinding wheel reinforcing members arranged side by side. The two grinding wheel strengthening components are respectively positioned at the two strengthening rib output positions of the double strengthening rib synchronous shaping section 4. The roller reinforcing component is used for extruding a side groove on one side of the top closed position of the two side plates of the reinforcing rib. The side grooves enable grooves and protrusions to be formed on opposite sides of the closed position of the two side plates of the reinforcing rib respectively; the bulges are embedded into the grooves, so that the two side plates of the reinforcing rib are tightly fixed together, and the structural stability of the reinforcing rib is improved.
As shown in fig. 2, the lead-in section 2 includes a support roller 2-1, a guide plate 2-2, a guide rod 2-3, and a width adjustment mechanism 2-4. A plurality of supporting rollers 2-1 which are sequentially and equally spaced along the length direction of the frame 1 are all rotatably connected to 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 both connected with the two guide rods 2-3 in a sliding way through sliding blocks. The joint of the guide plate 2-2 and the supporting roller 2-1 is provided with a yielding hole or a yielding groove so as to avoid interference between the guide plate 2-2 and the supporting roller 2-1. The two guide plates 2-2 respectively adjust the positions of the two guide plates in the width direction of the frame 1 through corresponding width adjusting mechanisms 2-4. The width adjustment mechanism 2-4 includes a 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. By turning the screw, the guide plate 2-2 is laterally adjusted in position. The distance between the two guide plates 2-2 is adjusted to be consistent with the width of the input coiled plate 6; by adjusting the positions of the two guide plates 2-2, the input position of the coiled plate 6 can be transversely adjusted, and the symmetry of the two processed reinforcing ribs is ensured.
As shown in fig. 3 and 4, all the double-groove bending unit 3-1 and the double-reinforcing-rib shaping unit 4-1 include a first rotation shaft 8 and a second rotation shaft 9. Both ends of the first rotating shaft 8 and the second rotating shaft 9 are rotatably connected to the frame 1 through bearings. The first rotating shaft 8 is located right above the second rotating shaft 9. The end parts of the first rotating shaft 8 and the second rotating shaft 9 are respectively fixed with a transmission gear 10; the two transmission gears 10 are engaged so that the first rotating shaft 8 and the second rotating shaft 9 can rotate in reverse synchronization. Any two adjacent second rotating shafts 9 are connected through a belt transmission mechanism 7. One of the second rotating shafts 9 is driven by a motor in such a manner that an output shaft of the motor is connected to the second rotating shaft 9 through a decelerator and a belt transmission mechanism 7.
As shown in fig. 3, each double-groove bending unit 3-1 further includes an upper pinch roller 3-1-1 and a lower pinch roller 3-1-2 on the basis of the first rotating shaft 8 and the second rotating shaft 9. The upper pinch roller 3-1-1 is fixed in the middle of the first rotating shaft 8. The two lower pinch rollers 3-1-2 are fixed on the corresponding second rotating shafts 9. Two annular bulges 3-1-3 are arranged on the outer circumferential surface of the strip-shaped upper pressing wheel 3-1-1; annular grooves 3-1-4 are formed in the outer circumferential surfaces of the two lower pressing wheels 3-1-2. The two annular projections 3-1-3 are aligned with the two annular recesses 3-1-4, respectively. The bottoms of the two annular protrusions 3-1-3 respectively extend into the tops of the two annular grooves 3-1-4. The two groups of annular bulges 3-1-3 are matched with the annular grooves 3-1-4, so that two rectangular pre-processed grooves can be pressed on the input plate 6. The annular grooves 3-1-4 can be formed on a disc-shaped workpiece; can be obtained by sandwiching a small diameter disk between two large diameter disks (a gap can be left between the large diameter disk and the small diameter disk, so that the width of the annular grooves 3-1-4 can be adjusted by moving the position of the large diameter disk).
The opposite sides of the two annular bulges 3-1-3 are convex round table tops 3-1-5. The inner edge of the round table surface 3-1-5 is aligned with the side surface of the annular groove 3-1-4 near the middle position of the second rotating shaft. The outer circumferential surface of the annular projection 3-1-3 is located at a centered position within the corresponding annular recess 3-1-4. During the formation of the pre-groove, the circular lands 3-1-5 will be in close contact with the plate material. So that the plate positioned inside the annular protrusion 3-1-3 is in close contact with the annular protrusion 3-1-3; the plate positioned outside the annular bulge 3-1-3 is suspended; therefore, for the areas of the plate material on the left and right sides of the outer circumferential surface of the annular projection 3-1-3, the friction force received by the plate material area located inside the annular projection 3-1-3 (the side closer to the middle of the plate material) is greater than the friction force received by the plate material area located outside the annular projection 3-1-3; so that the material required for forming the pre-processing groove on the plate is mainly provided by inwards shrinking the edge of the plate; the situation that the two pre-processing grooves are simultaneously formed to cause the middle position of the plate to be pulled to two sides to cause the damage of the plate is avoided.
Along the conveying direction of the plate 6, the annular width of the annular bulge 3-1-3 (namely, the difference between the outer diameter of the annular bulge 3-1-3 and the diameter of the upper pressing wheel 3-1-1) and the depth of the annular groove 3-1-4 of each double-groove bending unit 3-1 are gradually increased, the width of the annular groove 3-1-4 is gradually reduced, and the distance between the annular grooves 3-1-4 of the two lower pressing wheels 3-1-2 is gradually reduced, so that the pre-processing grooves on the plate 6 are gradually pressed deep and narrowed, and the shape of the grooves is gradually close to the requirement of the reinforcing ribs; and through gradually inwards being close to two pre-processing grooves in the shaping in-process for part material in pre-processing groove backup plate central point put on the panel can form the part that the pre-processing groove deepened required material, further avoids two pre-processing grooves simultaneous shaping to lead to panel intermediate position to be pulled to both sides and cause the condition of panel damage.
As shown in fig. 4, the dual-reinforcing-rib shaping unit 4-1 further includes two shaping subunits arranged side by side; the two shaping subunits are respectively aligned with the two lower pressing wheels 3-1-2 in the last double-groove bending unit 3-1. The shaping subunit comprises a first mounting seat 4-1-1, a second limiting wheel 4-1-2, a first limiting wheel 4-1-3 and a side pressing wheel 4-1-4. The first limiting wheel 4-1-3 and the second limiting wheel 4-1-2 are respectively fixed on a corresponding first rotating shaft 8 and a corresponding second rotating shaft 9. The first limiting wheels 4-1-3 are used for limiting the top surface position of the plate, and avoid deformation of the top surface of the plate. The second limiting wheel 4-1-2 is used for supporting the bottom surface of the pre-processed groove processed by the double-groove synchronous bending section 3. The first mounting seat 4-1-1 is fixed on the frame 1 and is positioned right below the corresponding second limiting wheel 4-1-2. The two side pressure wheels 4-1-4 are both rotatably connected to the first mounting seat 4-1-1 and are respectively positioned at two sides of the bottom of the first limit wheel 4-1-3. In the downward-upward direction, the axes of both side pressure wheels 4-1-4 are inclined to the side away from the first limit wheel 4-1-3.
The outer circumferential surface of the side pressing wheel 4-1-4 comprises a pressing surface 4-1-5 and a limiting surface 4-1-6 which are positioned on the upper side. In the contact position of the side pressure wheel 4-1-4 and the plate 6, the extrusion surface 4-1-5 is a vertical line, and the limit 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 of the two side plates of the pre-processing groove close to the opening in a vertical posture and extruding inwards, so that the opening is reduced; the limiting surfaces 4-1-6 of the two side pressure wheels 4-1-4 are used for guiding the two side plates of the pre-processing groove to an inclined posture at a position far away from the opening, so that the transition between the constant bottom surface width of the pre-processing groove and the gradually reduced opening width is realized.
In all shaping subunits for processing the same reinforcing rib, each side pressing wheel 4-1-4 positioned on the inner side of the first 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 opening closing process of the pre-processing groove; along the conveying direction of the plate 6, the distance between the two side pressure wheels 4-1-4 in each shaping subunit is gradually reduced; the preformed groove is eventually formed by progressive deformation into an upper closed portion and a lower triangular portion.
A limiting ring is integrally formed in the middle of the circumferential surface of the first limiting wheel 4-1-3 in the front two-reinforcing-rib shaping units 4-1; the bottom of the limiting ring stretches 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 pressure wheels 4-1-4. The first limit wheel 4-1-3 of the two reinforcing rib shaping units 4-1 at the back is not provided with a limit ring, because the tops of the two side surfaces of the pre-processing groove are very close, and the support from inside to outside is not needed.
As shown in fig. 5 and 6, the two wheel reinforcement assemblies are aligned with the two styling subunits, respectively; the grinding wheel strengthening component comprises a first grinding wheel 5-1, a second grinding wheel 5-2 and a driving component; the first grinding wheel 5-1 and the second grinding wheel 5-2 with vertical axes are arranged side by side and are rotationally connected on the frame. The linkage assembly comprises two synchronizing gears 5-5. The two synchronous gears 5-5 meshed with each other are respectively fixed with the bottom ends of the rotating shaft parts of the first grinding wheel 5-1 and the second grinding wheel 5-2. Thereby achieving synchronous counter-rotation of the first grinding wheel 5-1 and the second grinding wheel 5-2. The middle positions of the first grinding wheel 5-1 and the second grinding wheel 5-2 are aligned with the tops of the corresponding reinforcing rib output positions, so that the reinforcing ribs pass through the space between the first grinding wheel 5-1 and the second grinding wheel 5-2 and are extruded by the first grinding wheel 5-1 and the second grinding wheel 5-2, and the shape stability of the reinforcing ribs is improved.
The outer circumferential surface of the first grinding wheel 5-1 is provided with a pressurizing bulge 5-3; the outer circumferential surface of the second grinding wheel 5-2 is provided with a yielding gap 5-4. The pressurizing bulge 5-3 corresponds to the position of the abdication notch 5-4. Each time the first grinding wheel 5-1 and the second grinding wheel 5-2 rotate for a circle, the pressurizing bulge 5-3 and the yielding notch 5-4 are opposite to Ji Yici, and a side groove is extruded at the top of the reinforcing rib, so that the tops of the two side plates of the reinforcing rib are tightly combined together, and the structural stability of the reinforcing rib is improved.
On the basis, the first grinding wheel 5-1 and the second grinding wheel 5-2 can rotate under the friction force of the forward movement of the reinforcing ribs, and can also be driven by a separate motor to rotate, so that auxiliary power is provided for the forward movement of the reinforcing ribs.
As an alternative technical scheme, a cutting device 11 is arranged on one side of the reinforcing rib strengthening mechanism 5, which is far away from the double reinforcing rib synchronous shaping section 4, and the cutting device 11 cuts a plate with the reinforcing ribs with specified length through the lifting movement of a cutter.
As an alternative technical scheme, a plurality of auxiliary supporting wheels are arranged on part or all of the second rotating shafts. The position of the auxiliary supporting wheel is staggered with the position for processing the two reinforcing ribs; in the working process, the auxiliary supporting wheels are in contact with the bottom surface of the plate, so that the plate is kept flat in the processing process, and auxiliary power is provided for forward conveying of the plate.
The working principle of the invention is as follows:
Feeding one end of the coiled sheet metal into the lead-in section 2 in a tiled state; the plate enters the double-groove synchronous bending section 3 under the guidance of the leading-in section 2. The plate sequentially passes through each double-groove bending unit 3-1; each double-groove bending unit 3-1 synchronously forms two pre-processing grooves on the plate, and gradually deepens and narrows the two pre-processing grooves; each double-reinforcing-rib shaping unit 4-1 extrudes the opening of the pre-processing groove through the side pressure wheel, so that the opening of the pre-processing groove is gradually closed, a triangular groove body is formed at the lower part, and two reinforcing ribs with closed sections at the two sides are formed at the upper part. When the reinforcing ribs pass through the corresponding grinding wheel reinforcing assemblies, the pressurizing protrusions 5-3 are matched with the abdication notches 5-4 every time the two grinding wheels rotate for one circle, and grooves are pressed out on the side parts of the closed positions of the tops of the reinforcing ribs; the grooves enable the two side plates at the top of the reinforcing rib to be tightly attached together, and the deformation resistance of the reinforcing rib is improved.
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 remarkably improved; in addition, the top surface of the plate material is kept basically flat due to the closed top of the reinforcing ribs, so that the top surface of the plate material after the reinforcing ribs are formed can be used for bearing goods and can be used as a shelf partition plate.
Example 2
This embodiment differs from embodiment 1 in that: the first rotating shaft is not directly above the second rotating shaft, but directly below the second rotating shaft; the reinforcing bars processed in this embodiment are located above the main body of the sheet material.
