Since the size of the medium-sized products determines the stacking method, the multi-row parallel stacking method of small steel cannot be used, and only the single-row stacking method can be used. This stacking method has a slow rhythm and low output, which greatly limits the production capacity of the rolling mill. In order to match the production capacity of the rolling mill, it is an urgent problem to develop a new type of stacking and forming device for medium-sized U, Z steel sheet piles and H-beams.

[0012] The stacking forming process of a medium-sized U, Z steel sheet pile and H-shaped steel stacking forming device of the present invention is as follows: first, the specifications of the rolled products (U, Z steel sheet piles and H-shaped steel) are input into the control system, the control system controls the encoder at the tail of the motor, thereby controlling the position of the vehicle body, driving the motor to rotate, the rotation of the motor drives the reducer to rotate, the reducer drives the transmission shaft to rotate, the six groups of gears on the transmission shaft rotate, and the six groups of racks meshing therewith move downward, thereby driving the vehicle body assembled by the six groups of trolleys to move downward to position E, and position E depends on the specifications of the products rolled online, and then the row transport chain divides the 4 rows of U, Z steel sheet piles cut by the grouping into two groups and two rows of U, Z steel sheet piles through the dividing steel hook 1, one group is located at position 1 under the action of the dividing steel hook 1, and the other group is located at position 2 under the stopping action of the stopping hook 2, the two rows of U, Z steel sheet piles and H-shaped steel at position 2 are sucked by the energized flipping electromagnet (one), at which time the flipping electromagnet (one) is located at position C, and the flipping electromagnet (one) After sucking two rows of U and Z steel sheet piles and flipping 180°, they are located at position D. Then the flipping electromagnet (I) is powered off. The two rows of U and Z steel sheet piles fall on the transport chain, just at position 3. Then the flipping electromagnet (I) flips back 180° to position C again. During the above process, the transport chain does not stop conveying.

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] like Figure 1-4 As shown, this embodiment is a medium-sized U, Z steel sheet pile and H-shaped steel stacking forming device, including a trolley system, a track system, a transmission system, and a drive system.

[0026] The trolley system is composed of six groups of trolley assemblies, and six groups of trolley assemblies are arranged in sequence along the center line of the transmission shaft 7. The trolley assembly includes a car body 1, wheels 2, and racks 3. Two groups of wheels 2 are hinged on the A side of each group of car bodies 1, and two groups of wheels 2 are hinged on the B side of each group of car bodies 1. The six racks 3 are respectively fixed on the C sides of the six groups of car bodies 1. The four groups of wheels 2 on each group of trolley assemblies are stuck in the U track corresponding to the group in the track system. The trolley assembly can move up and down along the track. The connection relationship and movement of the remaining groups are the same as above. Figure 1 shown.

[0027] The track system includes a U-shaped track 4, and the U-shaped track 4 is arranged in sequence along the center line of the transmission shaft 7. Figure 1 As shown, each set of U-shaped rails 4 is fixed to the support frame D corresponding to the set of rails. Figure 2 shown.

[0028] The transmission system includes gears 5 and bearing seats 6. Six groups of gears 5 are arranged in sequence along the center line of the transmission shaft 7. Six groups of bearing seats 6 are arranged in sequence along the center line of the transmission shaft 7. Each group of gears 5 is meshed with a rack 3 in a trolley assembly corresponding to the group. Each group of bearing seats 6 is fixed to the D side of the support frame corresponding to the group. The connection relationship of the remaining groups is the same as the movement situation. The transmission shaft 7 is hinged on the six groups of bearing seats 6. One end of the transmission shaft 7 is connected to one end of the universal coupling 8 as shown in FIG. Figure 1 shown.

[0029] Example 2

[0030] On the basis of the above embodiment, the drive system includes a motor 12, a handle 11, a reducer 10, a base 9, and a universal coupling 8. The output shaft of the motor 12 is connected to one end of the handle 11, and the other end of the handle 11 is connected to the input shaft of the reducer 10. The output shaft of the reducer 10 is connected to one end of the universal coupling 8, and the other end of the universal coupling 8 is connected to one end of the transmission shaft 7. The motor 12 is fixed on the base 9, and an encoder is installed at the tail of the motor 12. The reducer 10 is also fixed on the base 9, and the base 9 is fixed on the civil engineering foundation as shown in Figure 1.

[0031] Example 3

[0032] On the basis of the above embodiment, the whole stacking forming process is as follows: first, the specifications of the rolled products (U, Z steel sheet piles and H-shaped steel) are input into the control system, and the control system controls the encoder at the tail of the motor 12, thereby controlling the position of the vehicle body 1, driving the motor 12 to rotate, the motor 12 rotates to drive the reducer 10 to rotate, the reducer 10 drives the transmission shaft 7 to rotate, the six sets of gears 5 on the transmission shaft 7 rotate, and the six sets of racks 3 meshing therewith rotate. The 4 rows of U and Z steel sheet piles are divided into two groups of two rows of U and Z steel sheet piles by the dividing hook 1. One group is located at position 1 under the action of the dividing hook 1, and the other group is located at position 2 under the stopping action of the stopping hook 2. The two rows of U and Z steel sheet piles and H-shaped steel at position 2 are sucked by the energized flipping electromagnet (I). At this time, the flipping electromagnet (I) is located at position C. The flipping electromagnet (I) sucks the two rows of U and Z steel sheet piles and flips them 180° to position D. Then the flipping electromagnet (I) is powered off, and the two rows of U and Z steel sheet piles fall on the transport chain, just at position 3. Then the flipping electromagnet (I) flips back 180° to position C again. In the above process, the transport chain does not stop conveying. The stop hook 3 needs to move the two rows of U and Z steel sheet piles at position three. The stop hook 3 also has the function of moving left and right, which is mainly used to stack H-shaped steel (to be explained later). The two rows of U and Z steel sheet piles at position 3 are sucked by the energized flip electromagnet (two). At this time, the flip electromagnet (two) is located at position A. The flip electromagnet (two) sucks the two rows of U and Z steel sheet piles and flips them 180° to position B. Then the flip electromagnet (two) is powered off, and the two rows of U and Z steel sheet piles fall on the six groups of car bodies 1. Then the flip electromagnet (two) moves back again. Flip 180° to position A, and then drive motor 12 to rotate, the rotation of motor 12 drives reducer 10 to rotate, reducer 10 drives transmission shaft 7 to rotate, six sets of gears 5 on transmission shaft 7 rotate, and six sets of racks 3 meshing therewith move downward, thereby driving the car body 1 assembled by six sets of trolleys to move downward. The displacement of the movement is controlled by the encoder, and the specific size is determined according to the product specifications or the leg height of the H-beam. At this point, the first layer of palletizing has been completed, and the above actions can be repeated to complete the second, third, and fourth layers of palletizing. Figure 3As shown, the stacking process of the first layer of H-beam stacking is exactly the same as that of the U and Z steel sheet pile stacking. When stacking the second layer, it is necessary to control the stop hook 3 to move to the left by a certain displacement, so that the two rows of H-beams can avoid the thickness of the legs when stacking the first layer, and perform leg staggered stacking. When stacking the third layer, it is necessary to control the stop hook 3 to move to the right back to the position when stacking the first layer, so that the two rows of H-beams can avoid the thickness of the legs when stacking the second layer, and perform leg staggered stacking. When stacking the fourth layer, it is necessary to control the stop hook 3 to move to the left back to the position when stacking the second layer, so that the two rows of H-beams can avoid the thickness of the legs when stacking the third layer, and perform leg staggered stacking. Figure 4 As shown, the entire stacking of U, Z steel sheet piles and H-shaped steel is now completed.

Figure 5 , 6 shown.

[0041] The entire pallet double flipping process is as follows: Here, a special mechanical structure is described. The mechanical structure composed of the flipping electromagnet (1) A1, the tail swing shaft hydraulic cylinder (1) A3, the bearing seat (1) A2, and the support (1) A4 is called a double rocker mechanism in mechanical principle. The characteristic of this structure is that there are dead points in the mechanism, such as Figure 3 shown. Similarly, the mechanical structure composed of the electromagnet (2) A5, the tail swing shaft hydraulic cylinder (2) A9, the bearing seat (2) A10, the support (2) A8, and the rocker arm A7 is also a double rocker mechanism in mechanical principle, and there are also dead points, such as Figure 3As shown, this mechanism also has a characteristic motion with symmetry (forward motion and reverse motion are symmetrical). The motion of this mechanism at the dead point is uncertain. In engineering practice, inertia or auxiliary power systems are usually used to help the mechanism pass the dead point to achieve the purpose of certain motion. First, let the six groups of flip electromagnets (one) 1 be in position A, and the six groups of electromagnets (two) A5 be in position C. The four rows of U, Z steel sheet piles and H-shaped steel on the row of transport chains are divided into two groups of two rows of U, Z steel sheet piles and H-shaped steel through the stop hook 1, and then the stop hook 2 Block the two rows of U, Z steel sheet piles and H-shaped steel at position 1 on the row of transport chains, and control the six sets of electromagnets (two) A5 to be energized through the control system to absorb the U, Z steel sheet piles and H-shaped steel at that location, and then drive the piston rods of the six sets of tail hydraulic cylinders (two) (also the above-mentioned rocker) to retract, and the six sets of flip arms (two) A6 rotate counterclockwise around their own hinge centers. At the same time, one end of the six sets of rocker arms A7 rotates counterclockwise around the centers of the ear plates hingedly fixed on the six sets of bearing seats (two) A10, and the other ends of the six sets of rocker arms A7 rotate around the centers of the ear shafts hingedly fixed on the six sets of electromagnets (two) A5. This This ensures that the angle between the six rocker arms A7 and the six flip arms (two) A6 remains unchanged during the counterclockwise rotation of the six flip arms (two) A6, thereby ensuring that the electromagnet (two) A5 remains the same as the state of position C during the counterclockwise rotation of the flip arms (two) A6, and the relative position between the two remains unchanged. In the above process, the motor A17 drives the reducer A14 to rotate, and the rotation of the reducer A14 drives the six flip arms (two) A6 to rotate synchronously. When the piston rods of the six tail hydraulic cylinders (two) continue to retract, when they reach the dead point of the mechanism (the tail center of the tail hydraulic cylinder, the tail hydraulic cylinder) When the center of the flat head of the pressure cylinder (or the center of the ear plate fixed on the flip arm (II) A6) and the rotation center of the flip arm (II) A6 are in a straight line in the same plane), the motor A17 drives the reducer A14 to rotate, and the reducer A14 drives the transmission shaft (II) A11 to rotate, thereby driving the six groups of flip arms (II) A6 to continue to rotate counterclockwise around their own hinge centers, and there is a certain movement across the dead point of the mechanism, and then the piston rods of the six groups of tail hydraulic cylinders (II) change from the retracted state to the extended state. When the piston rods of the six groups of tail hydraulic cylinders (II) are all extended, the flip arm (II) 6 just rotates. 180° from position C to position D, the two rows of U, Z steel sheet piles and H-shaped steel sheets attracted by the six groups of electromagnets (two) 5 are turned over 180° from position C to position D, and then the six groups of electromagnets (two) 5 are powered off through the control system, and the two rows of U, Z steel sheet piles and H-shaped steel are naturally placed on the row of transport chains, that is, position 2. At the same time, the stop hook 3 blocks the two rows of U, Z steel sheet piles and H-shaped steel, and the six groups of electromagnets are turned back 180° clockwise to return to the initial position C. According to the symmetrical characteristics of the double rocker mechanism, the clockwise back turning action process is symmetrical with the counterclockwise turning action process, which will not be described in detail here.Then, the control system controls the six groups of flip electromagnets (I) A1 to be energized, and the two rows of U and Z steel sheet piles and H-shaped steel at position 2 on the row of transport chains are sucked, and then the piston rods of the six groups of tail swing shaft hydraulic cylinders are driven to retract, and the six groups of flip electromagnets (I) 1 rotate counterclockwise around their own hinge centers. In the above process, the motor A17 drives the reducer A14 to rotate, and the rotation of the reducer A14 drives the six groups of flip electromagnets (I) A1 to rotate synchronously. When the piston rods of the six groups of tail hydraulic cylinders (II) continue to retract, when the dead point of the mechanism is reached (the tail center of the tail hydraulic cylinder, the flat head center of the tail hydraulic cylinder (or the center of the ear plate fixed on the flip electromagnet (I) A1), and the rotation center of the flip electromagnet (I) A1 itself are in a straight line in the same plane), at this time, the motor A17 drives the reducer A14 to rotate, and the reducer A14 drives the transmission shaft (II) A11 The six groups of flipping electromagnets (I) A1 rotate, thereby driving the six groups of flipping electromagnets (I) A1 to continue to rotate counterclockwise around their own hinge centers, and there is a certain movement beyond the dead point of the mechanism, and then the piston rods of the six groups of tail hydraulic cylinders (I) change from a retracted state to an extended state. When the piston rods of the six groups of tail hydraulic cylinders (I) are all extended, the flipping electromagnet (I) A1 just rotates 180° from position A to position B, and the two rows of U, Z steel sheet piles and H-shaped steel pages attracted by the six groups of flipping electromagnets (I) 1 flip 180° from position A to position B, and then the six groups of flipping electromagnets (I) 1 are powered off through the control system, and the two rows of U, Z steel sheet piles and H-shaped steel are naturally placed on the stack-type layer trolley, and then the six groups of flipping electromagnets (I) A1 flip back 180° clockwise to return to the initial position A, waiting to suck steel and flip again. According to the symmetrical characteristics of the double rocker mechanism, the clockwise back flipping action process is symmetrical with the counterclockwise flipping action process, which will not be described in detail here. At this point, the double flipping process of flipping electromagnet (I) A1 and electromagnet (II) A5 is completely completed. For H-shaped steel, I-shaped steel and channel steel stacking, it is necessary to adjust the position of the stop hook 3 in time, mainly because the legs of H-shaped steel, I-shaped steel and channel steel are stacked in an offset manner, and the reciprocating movement of the stop hook 3 is achieved by a set of four-bar linkage. Fig. 9As shown, the tail of the tail swing shaft hydraulic cylinder is hinged on the support A fixed on the support frame, the flat head of the tail swing shaft hydraulic cylinder is hinged on one end of the swing rod, the tail of the tail swing shaft hydraulic cylinder is equipped with a linear displacement sensor, the swing rod is hinged on the support B fixed on the support frame, the other end of the swing rod is hinged on one end of the stop hook 3, the other end of the stop hook 3 is hinged on one end of the connecting rod, and the other end of the connecting rod is hinged on the support C fixed on the support seat. By controlling the linear displacement sensor of the tail swing shaft hydraulic cylinder to control the displacement of the piston rod of the tail swing shaft hydraulic cylinder to control the swing amplitude of the swing rod, the left and right displacement of the stop hook 3 is controlled, thereby controlling the left and right positions of the H-shaped steel, I-shaped steel and channel steel at position 2, and realizing the staggered stacking function of the H-shaped steel, I-shaped steel and channel steel, and the rest of the process is the same as above. Repeating the above process can achieve continuous double flipping, and the double flipping device moves smoothly, greatly improves production efficiency, and is convenient and simple to maintain.
