DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-10 , the present invention provides a technical solution: See also Figure 2, 3 A trapezoidal keel production equipment includes a base 1 and a forming mold 2 and a forming mechanism arranged above the base 1. The forming mold 2 is a trapezoidal forming mold 2 with an opening at the bottom. The forming mechanism punches, bends and forms a blank plate and fits it to the surface of the forming mold 2 to form a trapezoidal keel 46. A groove 3 is set on the top of the forming mold 2 according to the shape requirements of the trapezoidal keel 46. A plurality of through holes 4 are set in the groove 3 along the length direction. The through holes 4 facilitate the punching of mounting holes 11 after the trapezoidal keel 46 is formed.

[0021] See also Figure 3 , 4 8, the forming mechanism includes a base 5, a bending assembly 6 and a stamping assembly 7. A support frame 8 is provided on the base 1. The forming mechanism is located above the shaping die 2 and is slidably arranged in the support frame 8. The base 5 is used to press the blank plate to keep the blank plate stable during the stamping process. A die groove 9 is provided at the bottom of the base 5. The stamping assembly 7 includes a stamping die 71 and a punch 72. The stamping die 71 is slidably arranged in the die groove 9 to form the recessed portion 10 of the blank plate. After the recessed portion 10 is formed, The mounting hole 11 at the position of the recessed portion 10 is punched out by the punch rod 72. The forming mechanism also includes a cylinder 12 fixed in the support frame 8. A driving rod 13 is fixed to the output end of the cylinder 12. The bottom end of the driving rod 13 extends into the stamping die 71 and is fixedly connected to a seat plate 14. Multiple groups of punch rods 72 are evenly distributed on the seat plate 14. The seat plate 14 drives multiple groups of punch rods 72 to slide up and down and is set in the stamping die 71, so that multiple groups of mounting holes 11 are punched out by the multiple groups of punch rods 72 through one downward pressure of the seat plate 14. See also Figure 4 , 8 The bottom of the base 5 is symmetrically provided with a pressing plate 33 assembly for pressing the blank plate on both sides of the die groove 9. The pressing plate 33 assembly includes a pressing wheel component 15 rotatably arranged at the bottom of the base 5. During the process of the punching die 71 punching the blank plate into the groove 3, the pressing wheel component 15 rotates to allow the blank plate to partially slide into the groove 3 and form a recessed portion 10. During the forming process of the recessed portion 10, the pressing wheel component 15 makes the blank plate material slide into the groove 3 in a stable and uniform amount, thereby ensuring the forming quality of the trapezoidal keel 46; See also Figure 3 , 8In order to make the forming mechanism form the trapezoidal keel 46 stably, the cylinder 12 can be provided with multiple groups, and a fixing plate 16 is provided on the outer wall of the driving rod 13 at the output end of each group of cylinders 12. The driving rod 13 is located between the fixing plate 16 and the base 5 and is sleeved with a first spring 17. The first spring 17 keeps a certain distance between the fixing plate 16 and the base 5 in the initial state, so that the fixing plate 16 is pressed against the blank plate by the base 5 and the stamping die 71 stamps the blank plate and then moves down. The base 5 is slidably arranged on the driving rod 13, and a plate groove 18 is provided in the stamping die 71 for the seat plate 14 to slide up and down. The outer wall of the punch rod 72 located in the plate groove 18 is sleeved with a second spring 19 that abuts against the seat plate 14. After the seat plate 14 pushes the stamping die 71 downward through the second spring 19 to punch down the blank plate to form a recessed portion 10, the second spring 19 begins to be squeezed to deform and drive the seat plate 14 to move downward, so that the punch rod 72 punches the recessed portion 10; See also Figure 8 , 9 10. In order to make the stamping die 71 stamp the blank plate and make the pressing wheel 151 assembly rotate a certain angle, so that the blank plate can send the deformation amount required for the formation of the recessed portion 10 into the groove 3, the pressing wheel component 15 includes a pressing plate 33 wheel and a meshing wheel 152. A linkage component 20 is provided between the stamping die 71 and the meshing wheel 152, which is used to drive the pressing wheel 151 to rotate and send the blank plate part into the groove 3 when the stamping die 71 stamps the blank plate. The linkage component 20 includes a double-sided rack 201 and a transmission gear 202. The stamping die The outer walls on both sides of 71 are symmetrically provided with transmission racks 21 meshing with the transmission gear 202, and the inner wall of the base 5 is provided with a rack groove 22 for the transmission rack 21 to slide up and down.

[0022] See also Figure 4 , 5 The bending assembly 6 includes a bending plate 61 and a resisting plate 62. The bending plate 61 is symmetrically arranged on both sides of the bottom of the base 5 and is rotatably arranged on the base 5. The cylinder 12 drives the driving rod 13 to move downward, so that the pressing plate 33 assembly presses the blank plate, the stamping die 71 stamps the middle part of the blank plate, the punch rod 72 punches the blank plate, and the resisting plate 62 moves downward and resists the bending plate 61 to drive the bending plate 61 to rotate and bend the blank plate. A first torsion spring (not shown in the figure) is connected between the bending plate 61 and the base 5 and is kept in a horizontal state by the first torsion spring in the initial state. When the bending plate 61 is in a horizontal state, the bottom of the bending plate 61 fits with the top end face of the blank plate, but does not press the blank plate, so that the blank plate can be bent more stably when the bending plate 61 rotates subsequently.

[0023] Extension plates 23 connected to the abutment plate 62 are symmetrically provided on both sides of the fixed plate 16. A gear 24 is rotatably provided at the bottom of the abutment plate 62. A rack channel 25 matching the gear 24 is provided on the upper surface of the bending plate 61. When the abutment plate 62 moves down and abuts against the bending plate 61, the gear 24 meshes with the rack channel 25 and rotates, making the abutment plate 62 more stable in the process of pressing down and driving the bending plate 61 to rotate.

[0024] See also Figure 3 , 4 5. A hook plate 26 is rotatably provided at the outermost end of the bending plate 61. One end of the hook plate 26 is arranged in an arc shape (a buffer avoidance pad is arranged on the inner wall of the arc), and the other end is provided with a rotating rod 27 which is rotatably connected with the bending plate 61. A second torsion spring (not shown in the figure) is connected to the rotating connection between the rotating rod 27 and the bending plate 61. A local tooth 28 connected with the rack channel 25 is arranged on the outer peripheral side of the rotating rod 27. After the push plate 62 moves down and the gear 24 is abutted against the gear 24 channel to complete the bending of the blank plate by the bending plate 61, the push plate 62 continues to move down to make the gear 24 mesh with the local tooth 28 and drive the rotating rod 27 to rotate until the hook plate 26 is opposite to the inclined foot plate 2002.

[0025] See also Figure 4 , 5 In order to position the blank plate placed on the trapezoidal shaping die 2, a limiting plate 29 is provided on the outer wall of one arc-shaped end of the hook plate 26, and the limiting plate 29 extends downward to position the blank plate. A folding plate 31 is provided on the limiting plate 29, and a slide groove 32 is provided below the limiting plate 29, and a pressing plate 33 (the pressing plate 33 is I-shaped) is provided in the slide groove 32 for pressing and positioning the blank plate. A third spring 30 is provided at the bottom of the folding plate 31 to press the pressing plate 33 downward. In the process of the bending plate 61 following the driving rod 13 to move downward, the pressing plate 33 continues to press the end of the blank plate, wherein the limiting plate 29 includes a transverse plate 291 and a vertical plate 292, and the transverse plate 291 extends outward to make the pressing plate 33 just located at the edge of the blank plate. In the initial state, the vertical plate 292 extends downward and fits the side of the blank plate.

[0026] See also Figure 3 , 8 The shaping mold 2 includes symmetrically arranged inclined foot plates 2002 and a cross plate 2001 connected between the inclined foot plates 2002 on both sides. A pressure plate groove 34 is provided at the bottom of the inclined foot plates 2002, and a shaping pressure plate 35 is provided at the bottom of the inclined foot plates 2002. A slide plate 36 that is slidably connected to the pressure plate groove 34 is provided at the top of the shaping pressure plate 35. A fourth spring 37 connected to the slide plate 36 is provided in the pressure plate groove 34. In the initial state, the fourth spring 37 pulls the slide plate 36 into the pressure plate groove 34. After one arc-shaped end of the hook plate 26 rotates to a position facing the shaping pressure plate 35, the shaping pressure plate 35 slides and presses one end of the blank plate into the arc-shaped interior of the hook plate 26 to complete the shaping.

[0027] See also Figure 3 , 6 7. A connecting plate assembly is provided between the inner end surface of the inclined foot plate 2002 and the shaping plate 35. The connecting plate assembly includes a transverse plate 381, a first hinge plate 382 and a second hinge plate 383. The transverse plate 381 is horizontally fixed to the inner wall of the inclined foot plate 2002. One end of the first hinge plate 382 is rotatably connected to the transverse plate 381, and the other end is rotatably connected to the second hinge plate 383.

The second hinge plate 383 A stop block 39 for cooperating with the limit plate 29 is provided at the connection with the first hinge plate 382. When the hook plate 26 rotates to a position relative to the shaping pressure plate 35, the limit plate 29 just rotates to the inner side of the inclined foot plate 2002 and abuts against the stop block 39, so that the connection between the first hinge plate 382 and the second hinge plate 383 moves toward the side of the inclined foot plate 2002 and pushes the shaping pressure plate 35 downward through the second hinge plate 383 until the shaping pressure plate 35 presses the edge of the blank plate into the arc-shaped end of the hook plate 26.

[0028] See also Figure 3 In order to push out the formed trapezoidal keel 46, a support seat 40 is arranged on one side of the base 1, and a long cylinder 41 is arranged on the top of the support seat 40. A trapezoidal keel adapter plate 42 is arranged at the output end of the long cylinder 41. The trapezoidal keel adapter plate 42 has the same shape as the trapezoidal keel 46. The long cylinder 41 can drive the trapezoidal keel adapter plate 42 to move and push out the formed trapezoidal keel 46 on the trapezoidal shaping mold 2. In addition, multiple groups of support plates are arranged on the base 1 to support the trapezoidal shaping mold 2 at a certain height. It should be noted that the support plate will not affect the rotation of the limit plate 29 to the inner side of the trapezoidal shaping mold 2. The base 1 is located below the trapezoidal shaping mold 2 and a pull-out box 43 is also slidably arranged to place the plates that are punched out during the forming process of the trapezoidal keel 46.

[0029] See also Figure 1 , 2 A trapezoidal keel includes symmetrically arranged inclined plates 44 and a recessed portion 10 connected between the tops of the inclined plates 44 on both sides. The recessed portion 10 is punched to form multiple groups of mounting holes 11 along the length direction, and an inner arc portion 45 is provided at one end of the inclined plate 44 away from the recessed portion 10.

[0030] See also Figure 1-10When the device is in use, the blank sheet material required for forming the trapezoidal keel 46 is placed on the trapezoidal shaping die 2 and located between the limiting plates 29 on both sides, and the cylinder 12 is started. The cylinder 12 drives the driving rod 13 to move downward, and the driving rod 13 moves downward to drive the bending assembly 6 and the stamping assembly 7 to move downward. During the downward movement of the driving rod 13, the pressing plates 33 on both sides of the bending plate 61 continue to press the two sides of the blank sheet, and the pressing wheel 151 at the bottom of the base 5 preferentially contacts the blank sheet and presses the blank sheet tightly against the trapezoidal shaping die. The driving rod 13 continues to move downward. At this time, the base 5 The seat 5 cannot move downward, and the driving rod 13 drives the stamping die 71 to move downward to stamp the blank plate through the action of the seat plate 14 and the second spring 19. During the stamping process of the stamping die 71 moving downward, the transmission rack 21 meshes with the transmission gear 202 and drives the transmission gear 202 to rotate. The transmission gear 202 rotates and drives the double-sided rack 201 to slide. The sliding of the double-sided rack 201 will drive the pressure wheel 151 to rotate through the engagement with the gear 24, thereby sending part of the blank plate into the groove 3 and punching out the recessed portion 10 through the stamping die 71.

[0031] After the recessed portion 10 is formed, the driving rod 13 continues to move downward. At this time, the stamping die 71 cannot move downward. The driving rod 13 will drive the seat plate 14 to move downward and drive the bottom plate to move downward. The seat plate 14 moves downward to drive the punch rod 72 to move downward to punch the recessed portion 10. The downward movement of the push plate 62 will drive the bending plate 61 to rotate through the abutment between the gear 24 and the gear 24 channel, thereby bending the blank plate. After the blank plate is completely attached to the outer wall of the inclined foot plate 2002, the push plate 62 continues to move downward to make the gear 24 mesh with the local tooth 28 and drive the hook plate 26 to rotate. During the rotation of plate 26, the edge of the blank plate will bend around the bottom of the shaping plate 35, and the hook plate 26 will continue to rotate. At this time, the limit plate 29 will abut against the stop block 39, and drive the connection between the first hinge plate 382 and the second hinge plate 383 to move toward the side of the inclined foot plate 2002, thereby pushing the shaping plate 35 to move toward the side of the hook plate 26, and pressing the edge of the blank plate into the hook plate 26. At this time, the driving rod 13 drives the seat plate 14 to move downward, and the punch rod 72 completes the punching of the recessed portion 10, and the punched plate falls into the pull-out box 43 for collection.

[0032] After the trapezoidal keel 46 is formed, the cylinder 12 drives the driving rod 13 to move upward, driving the abutment plate 62 to move upward, and at the same time driving the seat plate 14 to move upward. The upward movement of the abutment plate 62 will disengage from the abutment with the local teeth 28. Under the action of the second torsion spring, the hook plate 26 will return to its initial position and lose the abutment with the abutment block 39. Under the action of the fourth spring 37, the slide plate 36 will slide into the pressure plate groove 34. The driving rod 13 continues to move upward, driving the stamping die 71 to move upward. Under the action of the second spring 19, the stamping die 71 will slide to the top of the die groove 9, and the cooperation of the transmission rack 21 and the transmission gear 202 will drive the double-sided rack 201 to return to its initial position. In addition, the upward movement of the driving rod 13 will also drive the abutment plate 62 to move upward to its initial position, so that the bending plate 61 is restored to a horizontal state under the action of the first torsion spring.

[0033] Then the long cylinder 41 is started, and the long cylinder 41 drives the trapezoidal keel adapter plate 42 to move and push out the trapezoidal keel 46 on the trapezoidal shaping die 2 so as to perform the stamping of the trapezoidal keel 46 next time.
