When the shaping block moves up, the rotation of the grinding plate is used to push the U-shaped bracket to the inside of the opening groove four, so that it can move horizontally while moving up, so that the triangular block two can always withstand the squeezing force from the U-shaped bracket. Finally, the convex block is used to bend and fold the side of the steel plate, thereby reducing the use of redundant equipment and reducing the prefabrication procedures, making the prefabrication process simple and easy.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1

[0041] like Figure 1-5 As shown, the present embodiment discloses a forming device for prefabricated guide grooves of assembled support piles, comprising a workbench 1, wherein two symmetrically arranged L-shaped limit blocks 2 are arranged at the upper end of the workbench 1, and the ends of the two L-shaped limit blocks 2 close to each other are inclined surfaces with the same deflection angle as the left and right ends of the shaping block 7, respectively. The shaping block 7 and the inclined surfaces of the L-shaped limit blocks 2 are used to roll the steel plate into a desired shape, and a portion of the upper ends of the two L-shaped limit blocks 2 close to each other is provided with a movable groove 21 penetrating through the lower end thereof, and the inside of the two movable grooves 21 is jointly provided with an adjustment mechanism 8 extending to the outside thereof, and the adjustment mechanism 8 is used to extrude and limit steel plates of different thicknesses, thereby reducing the use of redundant equipment and thus reducing the working cost;

[0042] It can be seen from this that the steel plate is placed horizontally at the angle between the horizontal and vertical parts of the two L-shaped limit blocks 2, and then the adjustment mechanism 8 is used to extrude and limit the steel plate to avoid the steel plate from shifting when it is extruded and shaped, resulting in a change in the bending position, thereby producing defective products.

[0043] In order to adjust the bending changes of steel plates of different thicknesses, please refer to Figure 2-5The adjusting mechanism 8 includes two L-shaped limit plates 81 which are respectively slidably connected to the inside of the two moving grooves 21 on the same side. The ends of the horizontal parts of the two L-shaped limit plates 81 which are away from each other are each provided with an empty groove 82. The empty groove 82 is an L-shaped storage groove, and its vertical part extends into the vertical part of the L-shaped limit plate 81. The inside of the empty groove 82 is provided with an L-shaped limit plate 88 whose horizontal part extends to the outside of the L-shaped limit plate 81. The size of the vertical part of the L-shaped limit plate 88 is smaller than the size of the vertical part of the empty groove 82, so that the vertical part of the L-shaped limit plate 88 can move left and right in the empty groove 82. The middle side of the upper part of the vertical part of the L-shaped limit plate 81 is provided with a through groove 83 which runs through its left and right outer end walls and is connected to the empty groove 82, so that the trapezoidal block 23 can pass through the through groove 83 and extend into the empty groove 82 to limit the parallelogram plate 89.

[0044] Specifically, an open groove 22 is provided on the upper part of the inner wall of the movable groove 21 on one side away from the inclined surface of the L-shaped limit block 2, and a triangular block 221 is provided inside the open groove 22, the lower part of which extends to the inside of the through groove 2 83, and a trapezoidal block 23 is provided on the upper part of the inner wall of the movable groove 21 on one side close to the inclined surface of the L-shaped limit block 2, and the trapezoidal block 23 and the triangular block 221 are located at the same horizontal height, that is, the inclined surface of the triangular block 221 will form a parallelogram together with the inclined surface of the trapezoidal block 23 to limit the parallelogram plate 89, and a parallelogram plate 89 is provided in the middle part of the upper end of the L-shaped limit plate 28 for sliding connection between the triangular block 221 and the trapezoidal block 23, and the position of the L-shaped limit plate 28 is adjusted by sliding the parallelogram plate 89 between the triangular block 221 and the trapezoidal block 23, so that it slides left and right in the empty groove 82;

[0045] From the above, it can be seen that when the L-shaped limit plate 81 is controlled to move downward to squeeze and limit the thinner steel plate, the L-shaped limit plate 81 will use the empty slot 82 to limit the L-shaped limit plate 88 and control it to move downward together, and the L-shaped limit plate 88 uses the parallelogram plate 89 to slide between the triangular block 221 and the trapezoidal block 23 to make the L-shaped limit plate 88 move horizontally while moving downward, so that the horizontal part of the L-shaped limit plate 88 is retracted into the empty slot 82, reducing the bending length of the thinner steel plate, avoiding the bending part being too long, resulting in the reduction of the interface, and affecting the connection of the remaining prefabricated support piles.

[0046] In order to facilitate the precise adjustment of the up and down moving distance of the L-shaped limit plate 81, specifically, the upper end of the L-shaped limit block 2 is provided with a convex bracket 27 located in the same vertical plane as the moving groove 21, and the horizontal part in the middle of the convex bracket 27 is located directly above the moving groove 21, and the upper end of the convex bracket 27 is provided with a threaded rod 28 with a turntable on the top, and the lower part of the threaded rod 28 passes through the convex bracket 27 and is rotatably connected to the L-shaped limit plate 81, that is, by rotating the threaded rod 28, the threaded rod 28 threadedly connected to the convex bracket 27 can drive the L-shaped limit plate 81 to move up and down, so as to adjust the position of the L-shaped limit plate 81 and perform extrusion limiting on steel plates of different thicknesses.

[0047] In addition, in order to enhance the structural stability of the L-shaped limit plate 81, specifically, the upper end of the L-shaped limit block 2 is provided with two slide grooves 24 located outside the movable groove 21, and the inner side walls of the two slide grooves 24 close to the movable groove 21 are provided with a card groove 25 penetrating the inner wall of the movable groove 21, and the inner upper side of the L-shaped limit plate 81 is provided with two movable grooves 84 penetrating the left and right outer end walls of the L-shaped limit plate 81 respectively, and the interior of the movable groove 84 is provided with a blocking rod 86 slidably connected to the inside of the card groove 25, and the blocking rod 86 is away from the side of the L-shaped limit plate 81 The arc-shaped structure allows the blocking rod 86 to be completely retracted into the moving groove 2 84 after being squeezed into the card slot 25 by the squeezing plate 261, so that the L-shaped limit plate 1 81 can continue to move up and down. A plurality of springs 3 85 are provided between the blocking rod 86 and the moving groove 2 84 at one end close to each other. Under the action of the springs 3 85, the blocking rod 86 moves horizontally outward through the card slot 25 and into the slide groove 1 24, so that the L-shaped limit plate 1 81 can be hung in the moving groove 1 21 to avoid falling or being squeezed upward by the steel plate being squeezed and bent.

[0048] The two sliding grooves 24 are each provided with an extrusion plate 261 inside, and the side of the extrusion plate 261 near the moving groove 21 is an inclined structure, which is convenient for cooperating with the arc-shaped structure of the stopper 86 to squeeze the stopper 86 to the outside of the sliding groove 24, and the upper ends of the two extrusion plates 261 are jointly provided with a pressing plate 26, and the lower end of the pressing plate 26 is provided with a plurality of springs 262 on the side away from the extrusion plate 261. When it is necessary to adjust the height of the L-shaped limit plate 81, the pressing plate 26 is pressed to make the extrusion plate 261 move downward to squeeze the stopper 86, so that the stopper 86 is retracted into the slot 25, and then the arc-shaped structure of the stopper 86 is used to make it fully retracted into the moving groove 24 when it receives the extrusion force of moving up or down, so that the L-shaped limit plate 81 can be moved up and down for adjustment, and after the movement is completed, the stopper 86 re-enters the other slot 25 under the action of the spring 3 85 to fix the L-shaped limit plate 81;

[0049] In order to make the raised part of the steel plate more flat, please refer to Figure 4-5 The ends of the two L-shaped limit blocks 2 that are close to each other are each provided with a slide groove 29 that is connected to the movable groove 21, and the ends of the two L-shaped limit plates 81 that are close to each other are jointly provided with a top plate 87 that is slidably connected to the inside of the slide groove 29, so that the top plate 87 can move up and down with the L-shaped limit plate 81.

[0050] Therefore, the specific implementation of this embodiment is:

[0051] First, press the pressing plate 26, and use the inclined part of the extrusion plate 261 to squeeze the blocking rod 86 into the slot 25, then rotate the threaded rod 28 to drive the L-shaped limit plate 1 81 to move downward to extrude and limit the thinner steel plate, and at the same time use the empty slot 82 to limit the L-shaped limit plate 2 88 and control it to move downward together, and the L-shaped limit plate 2 88 uses the parallelogram plate 89 to slide between the triangular block 1 221 and the trapezoidal block 23 to make the L-shaped limit plate 2 88 move horizontally while moving downward, so that the horizontal part of the L-shaped limit plate 2 88 is retracted into the empty slot 82, reducing the bending length of the thinner steel plate.

[0052] Embodiment 2

[0053] This embodiment further improves the forming of the prefabricated guide groove of the support pile on the basis of the first embodiment, such as Figure 6-12 As shown, a convex groove 11 penetrating through the lower end is provided in the middle of the upper end of the workbench 1, and limiting grooves 12 penetrating through the upper and lower ends of the workbench 1 are provided on the front and rear inner side walls of the convex groove 11, and a storage box 6 communicating with the convex groove 11 is provided at the lower end of the workbench 1, and a shaping block 7 is provided together with the inner cavity of the storage box 6, the convex groove 11 and the limiting groove 12, and a supporting pile body 10 is provided between the lower end of the top plate 87, the ends of the two L-shaped limiting blocks 2 close to each other and the outer surface of the shaping block 7, and an opening groove 2 61 penetrating through the lower end is provided in the middle of the bottom wall of the inner cavity of the storage box 6, and the shaping block 7 is pushed upward from the lower part through the opening groove 2 61 to stamp the steel plate horizontally placed on the workbench 1, so that it is deformed into a desired shape, and the left and right outer end walls of the storage box 6 are provided with an opening groove 3 63 penetrating through its inner cavity;

[0054] In order to make the middle of the steel plate be punched into the required shape, please refer to Figure 7-10A support frame 3 is provided at the lower end of the workbench 1, and a support plate 4 is provided at the middle side of the bottom of the support frame 3, and the lower end surface of the support plate 4 is at the same horizontal height as the lower end surface of the support frame 3, that is, the support plate 4 can contact with the ground to prevent the support plate 4 from bending under the reaction force of the hydraulic cylinder 5, thereby affecting the normal operation of the hydraulic cylinder 5. A hydraulic cylinder 5 is provided at the upper end of the support plate 4, and an adapter plate 62 slidably connected to the second opening groove 61 is provided at the upper part of the piston rod of the hydraulic cylinder 5. The hydraulic cylinder 5 controls the adapter plate 62 to move upward to push the shaping block 7 upward, thereby squeezing the steel plate horizontally placed on the workbench 1 to make it into a desired shape;

[0055] From the above, it can be seen that the hydraulic cylinder 5 is used to control the upward movement of the adapter plate 62 and the shaping block 7, so as to extrude the steel plate placed between the two L-shaped limit blocks 2, and the inclined surfaces of the L-shaped limit blocks 2 and the shaping block 7 are used to form the required trapezoidal structure in the middle of the steel plate, so as to facilitate the subsequent processing and assembly.

[0056] In order to deform the middle of the steel plate and bend the sides of the steel plate at the same time, please refer to Figure 8 The upper end of the workbench 1 is provided with two symmetrically arranged L-shaped grooves 13 connected to the horizontal part of the convex groove 11. The top wall of the horizontal part of the L-shaped groove 13 is provided with a connecting plate 131. The side of the connecting plate 131 away from the convex groove 11 is provided with a rotating plate 132. The end of the rotating plate 132 close to the L-shaped limiting plate 1 81 and the end away from the L-shaped limiting plate 1 81 are respectively provided with a convex block 133 and a triangular block 134. The triangular block 134 is convenient for the rotating plate 132 to better withstand the extrusion force from the U-shaped bracket 9, so that the rotating plate 132 and the convex block 133 are rotated to extrude and bend the side of the steel plate;

[0057] In addition, the height of the protrusion 133 is equal to the distance between the top wall of the horizontal part of the protrusion 133 and the upper end of the workbench 1, so that the protrusion 133 is completely retracted in the L-shaped groove 13 before rotating out, so that it cannot have a negative impact on the placement of the steel plate.

[0058] It can be seen that by pushing the triangular block 134, the rotating plate 132 is flipped upward, forcing the side of the steel plate to bend, and then the protrusion 133 is used to cooperate with the horizontal part of the L-shaped limit plate 1 81 and the L-shaped limit plate 2 88 to bend the bent side of the steel plate again, so that the side of the steel plate is bent into a U shape, which is convenient for the later assembly and connection of multiple shaping steel plates.

[0059] For further information, see Figure 10-11, the left and right outer end walls of the shaping block 7 are both provided with an opening groove four 71, and the insides of the two opening grooves four 71 are both provided with a U-shaped bracket 9 extending to the outside of the opening groove three 63, and one of the vertical parts of the U-shaped bracket 9 is slidably connected in the opening groove four 71, and a vertical part of the U-shaped bracket 9 away from the shaping block 7 is located in the same vertical plane as the L-shaped groove 13, and a plurality of springs two 72 are provided between a vertical part of the U-shaped bracket 9 located inside the opening groove four 71 and the inner side wall of the opening groove four 71, so that after the U-shaped bracket 9 has squeezed the triangular block two 134, it will return to the initial position under the action of the spring two 72, so as to facilitate the subsequent squeezing of the part of the triangular block two 134 away from the rotating plate 132;

[0060] Furthermore, a through groove 14 penetrating the inner wall of the convex groove 11 is provided on the inner wall of the horizontal part of the L-shaped groove 13 near the convex groove 11, and a grinding plate 141 for squeezing the U-shaped bracket 9 to move is provided on the top wall of the through groove 14. A portion of the grinding plate 141 away from the top wall of the through groove 14 extends to the inside of the opening groove 471 and is placed on the horizontal part of the U-shaped bracket 9. In the initial state, the grinding plate 141 and the vertical part of the U-shaped bracket 9 do not contact each other. In the working state, a portion of the grinding plate 141 away from the through groove 14 abuts against the U-shaped bracket 9. On the vertical part inside the opening groove four 71, that is, the grinding plate 141 passes through the through groove 14, the opening groove three 63 and the opening groove four 71 in the initial state, and is parked on the horizontal part of the U-shaped bracket 9. Then, when the shaping block 7 moves up to extrude the steel plate, the grinding plate 141 will continue to rotate and tilt, so that it will continue to go deeper into the opening groove four 71. When the vertical part of the U-shaped bracket 9 located outside the opening groove four 71 contacts with the triangular block two 134, the grinding plate 141 is against the vertical part of the U-shaped bracket 9 located inside the opening groove four 71.

[0061] Therefore, the specific implementation of this embodiment is:

[0062] The adapter plate 62 and the shaping block 7 are pushed upward by the hydraulic cylinder 5 to squeeze the middle part of the steel plate. When the shaping block 7 moves up to the vertical part of the U-shaped bracket 9 and contacts the triangular block 2 134, the grinding plate 141 is against the vertical part of the U-shaped bracket 9 located inside the opening groove 4 71, and then the shaping block 7 continues to move upward, which will cause the grinding plate 141 to squeeze the U-shaped bracket 9 toward the inside of the opening groove 4 71, so that the U-shaped bracket 9 will move horizontally while squeezing the triangular block 2 134 to rotate the rotating plate 132, so that the triangular block 2 134 can always be subjected to the squeezing force of the U-shaped bracket 9, and then the rotating plate 132 can be rotated until the steel plate is bent into the desired shape.

[0063] It should be noted that the specific installation method, circuit arrangement and connection method, and control method of the hydraulic cylinder 5 used in the above-mentioned embodiment 2 are all conventional designs in the prior art and will not be elaborated in detail in the present invention.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
