[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 2-8 The present invention provides a technical solution:

[0034] See Figure 2 A combination hanger production equipment for trapezoidal and square keel ribs includes a base 1, a lower mold base 2 on top of the base 1, and a support frame 3. The lower mold base 2 is located in the middle of the support frame 3, and a hanger mold opening 4 is provided in the middle of the lower mold base 2. A cylinder 5 is provided on the top of the support frame 3, and a hanger punch 6 is provided at the bottom of the output end of the cylinder 5, directly opposite the hanger mold opening 4. The hanger punch 6 extends into the hanger mold opening 4 through the downward movement of the cylinder 5 to punch out the hanger blank sheet 7. The shape and size of the hanger punch 6 are consistent with the hanger blank sheet 7 (see reference). Figure 8 They have the same shape and size;

[0035] See Figure 2-4A stabilizing seat 8 is provided inside the hanging die 4, sliding up and down. The top end face of the stabilizing seat 8 is initially flush with the top end face of the lower die 2. The stabilizing seat 8 is used to cooperate with the hanging punch 6 after the blank plate 7 is punched out, pressing the blank plate 7 down for grinding. The hanging punch 6 includes an outer die head 61 and an inner die head 62. The outer die head 61 is slidably sleeved on the outside of the inner die head 62. An integrated fixing member 9 is provided between the outer die head 61 and the inner die head 62. The integrated fixing member 9 is symmetrically arranged on both sides of the hanging punch 6. The integrated fixing member 9 includes a locking rod 91 and a first spring 92. The outer die head 61 is provided with a sliding hole 10 for the locking rod 91 to slide horizontally. The inner die head 62 is provided with an insertion hole 11 for one end of the locking rod 91 to be inserted at the position opposite to the sliding hole 10. The inner wall of the sliding hole 10 is provided with A limiting groove 12 is provided. The locking rod 91 is located on the outer wall of the sliding hole 10 and is slidably connected to the limiting groove 12. The first spring 92 is set in the limiting groove 12 to abut against the limiting plate 13 and drive the locking rod 91 to insert into the insertion hole 11. In the initial state, the locking rod 91 is located in the outer mold head 61 and the inner mold head 62, so that the outer mold head 61 and the inner mold head 62 are kept in an integral state for stamping the blank plate 7 of the hanging part. The lower mold base 2 is provided with an unlocking part of the unlocking integral fixing part 9, which is used to make the outer mold head 61 and the inner mold head 62 slide relative to each other after stamping. The top of the lower mold base 2 is symmetrically provided with side plates 14 on both sides of the hanging part mold opening 4. The end of the locking rod 91 away from the insertion hole 11 extends into the side plate 14 and is connected to a vertical rod 15. The side plate 14 is provided with The groove 16 allows the vertical rod 15 to slide up and down. The unlocking mechanism includes an unlocking rod 17 located at the bottom of the groove 16. The bottom of the vertical rod 15 has a first inclined surface 18, and the top of the unlocking rod 17 has a second inclined surface 19 that abuts against the first inclined surface 18. After the hanging punch 6 punches out the blank plate 7, the cylinder 5 continues to drive the hanging punch 6 to move down. The second inclined surface 19 on the unlocking rod 17 will abut against the first inclined surface 18 on the locking rod 91 and drive the locking rod 91 to disengage from the insertion hole 11, so that the outer mold head 61 and the inner mold head 62 can slide relative to each other. The width of the groove 16 is greater than the width of the vertical rod 15. The bottom of the groove 16, next to the unlocking rod 17, has a magnetic attractor 20 for magnetically attracting the vertical rod 15. After the locking rod 91 disengages from the insertion hole 11, the magnetic attractor 20 attracts the vertical rod 15. To keep the vertical rod 15 in a stable position, the inner die head 62 is provided with a sliding groove 21 on the outer wall of the insertion hole 11. The sliding groove 21 extends upward from the insertion hole 11. When the inner die head 62 slides downward relative to the outer die head 61, the locking rod 91 can move within the sliding groove 21. When the outer die head 61 subsequently moves upward, it can drive the locking rod 91 through the bottom inner wall of the insertion hole 11 of the inner die head 62, so that the locking rod 91 is re-inserted into the insertion hole 11. It should be noted that the bottom of the two side plates 14 is provided with a positioning groove 22. During stamping, one end of the coiled steel coil passes through the positioning groove 22. The steel coil moves a certain distance before one stamping is performed. After the stamped blank slab 7 is reset, the steel coil continues to move a certain distance to convey the stamped blank slab 7 backward.The blank sheet material 7 can be collected in a collection box at the rear end of the lower mold base 2.

[0036] See Figure 2 , 3 5. The stabilizing seat 8 includes an outer stabilizing seat 81 and an inner stabilizing seat 82. The outer stabilizing seat 81 is slidably sleeved on the outside of the inner stabilizing seat 82. A clamping member is provided between the outer stabilizing seat 81 and the inner stabilizing seat 82. The clamping member keeps the outer stabilizing seat 81 and the inner stabilizing seat 82 flush during the stamping process. The clamping member includes a second spring 23. A side groove 24 is provided on the outer wall of the inner stabilizing seat 82. An extension plate 25 is provided on the inner wall of the outer stabilizing seat 81 and forms an up-and-down sliding connection with the side groove 24. The bottom end of the second spring 23 is fixed to the bottom inner wall of the side groove 24, and the top end abuts against the bottom end face of the extension plate 25. A third spring 26 is provided at the top of the base 1 inside the hanging die 4. The top of the third spring 26 abuts against the bottom of the inner stabilizing seat 82.

[0037] See Figure 2 , 3 5, 6, also include a grinding assembly disposed within the lower mold base 2. The grinding assembly includes a pressure plate 30 and an airbag 28. A mold groove 27 is provided on the inner wall of the hanging part mold opening 4. Both the airbag 28 and the pressure plate 30 are located within the mold groove 27. Multiple sets of pressure plates 30 are provided, and the airbags 28 are located between the pressure plates 30. A grinding layer 29 is provided on the inner circumference of the airbag 28. The grinding layer 29 can be made of sandpaper or other grinding materials. The sandpaper covers the side circumference of the airbag 28 facing the hanging part mold opening 4. The lower mold base 2 is provided with a drive assembly 32 that drives the pressure plate 30 to move and compresses the airbag 28. After the airbag 28 is compressed, the grinding layer 29 is located within the mold opening 4. The outer periphery of the blank plate 7 is ground inside the die opening 4. During stamping, the airbag 28 is completely located inside the die groove 27, which does not affect the stamping of the blank plate 7. In addition, before the inner die head 62 and the inner stabilizing seat 82 clamp the blank plate 7 and move it down for grinding, the outer die head 61 moves upward relative to the inner die head 62, and the outer stabilizing seat 81 moves downward relative to the inner stabilizing seat 82, so that the outer periphery of the blank plate 7 is exposed for grinding. This method can ensure the grinding effect of the blank plate 7 and also prevent the hanging punch 6 and the stabilizing seat 8 from being ground, thus protecting the hanging punch 6, the stabilizing seat 8, and the grinding components.

[0038] See Figure 5-7To achieve better grinding effect on the blank plate 7 by the grinding assembly, the airbag 28 includes a first airbag 281 and a second airbag 282. A partition 31 is provided in the mold groove 27. The first airbag 281 and the second airbag 282 are located on the upper and lower sides of the partition 31, respectively. The pressing plate 30 is provided in two sets, located above the first airbag 281 and below the second airbag 282, respectively. The driving assembly 32 includes a bidirectional lead screw 321 and a driving rod 322. The bidirectional lead screw 321 is rotatably mounted on the partition 31, and both ends of the bidirectional lead screw 321 pass through the partition 31. Two sets of pressure plates 30 are connected by threads. The bottom end of the bidirectional screw 321 extends downward. The outer wall of the lower part of the bidirectional screw 321 is provided with a spiral groove 33. The base 1 is provided with a sliding plate 35 that slides up and down. The rack 41 and the drive rod 322 are both fixed to the top of the sliding plate 35. The outer wall of the drive rod 322 is provided with a guide shaft 34 that slides with the spiral groove 33. The base 1 is provided with a sliding plate groove 36 for the sliding plate 35 to slide up and down. The bottom inner wall of the sliding plate groove 36 is provided with a fourth spring 37. The top of the fourth spring 37 abuts against the bottom of the sliding plate 35.

[0039] See Figure 2 , 3 5.7. The separation method of the outer stabilizer 81 and the inner stabilizer 82 is as follows: the inner wall of the outer stabilizer 81 is provided with a vertical groove 38, and the vertical groove 38 is provided with a tooth 39. The outer side of the inner stabilizer 82 is rotatably provided with a gear 40 that meshes with the tooth 39. The base 1 is provided with a rack 41 for meshing with the gear 40. The inner stabilizer 82 is provided with a rack groove 42 for the rack 41 to be inserted into on one side of the gear 40. When the rack 41 moves in the rack groove 42 and drives the gear 40 to rotate, the outer stabilizer 81 will be displaced downward relative to the inner stabilizer 82. In this way, when the grinding assembly grinds the outer periphery of the blank, the outer stabilizer 81 has been displaced to the bottom of the grinding assembly. In the initial stage, the stabilizing seat 8 moves downward. The rack 41 slides into the rack groove 42 and drives the gear 40 to rotate. Through the cooperation with the tooth 39, the outer stabilizing seat 81 is displaced downward. After the top of the rack groove 42 of the inner stabilizing seat 82 abuts against the top of the rack 41, the inner stabilizing seat 82 continues to move downward. It will drive the slide plate 35 to move downward through the rack 41. The downward movement of the slide plate 35 will drive the drive rod 322 to move downward. The downward movement of the drive rod 322 will drive the bidirectional lead screw 321 to rotate through the cooperation of the guide shaft 34 and the spiral groove 33. This will drive the pressure plates 30 on the upper and lower sides to move towards each other, thereby squeezing the first airbag 281 and the second airbag 282, so that the polishing layer 29 is exposed in the hanging die opening 4. After the blank plate 7 moves downward and contacts the polishing layer 29, polishing will be performed.

[0040] Please see Figure 2-8 When using this device, one end of the steel coil is passed through the positioning groove 22 of the side plate 14, and the steel coil can be punched once after moving a certain distance.

[0041] During stamping, cylinder 5 drives the hanging die head to move downward. The hanging die head first contacts the steel coil and, together with the lower stabilizing seat 8, presses the steel plate. The hanging punch 6 continues to move downward to punch out a blank plate 7 and, together with the stabilizing seat 8, clamps the blank plate 7 downward. During the downward movement of the blank plate 7, the integrated fixing part 9 will move downward in the groove 16 and cause the vertical rod 15 to abut against the unlocking rod 17. Under the action of the first inclined surface 18 and the second inclined surface 19, the unlocking rod 17 will be disengaged from the insertion hole 11, and the vertical rod 15 will be magnetically fixed by the magnetic attractor 20. At the same time, the stabilizing seat 8 moves downward, and the rack 41 slides into the rack groove 42 and drives the gear 40 to rotate. Through the cooperation with the tooth part 39, the outer stabilizing seat 81 is displaced downward, so that the outer periphery of the blank plate 7 is exposed outside the inner die head 62 and the inner stabilizing seat 82. After the top of the rack groove 42 of the inner stabilizer 82 abuts against the top of the rack 41, the inner stabilizer 82 continues to move downward, which will drive the slide plate 35 to move downward through the rack 41. The downward movement of the slide plate 35 will drive the drive rod 322 to move downward. The downward movement of the drive rod 322 will drive the bidirectional lead screw 321 to rotate through the cooperation of the guide shaft 34 and the spiral groove 33, thereby driving the pressure plates 30 on the upper and lower sides to move towards each other, thereby squeezing the first airbag 281 and the second airbag 282, so that the polishing layer 29 is exposed in the hanging die opening 4. When the blank plate 7 moves downward, it can first pass through the polishing layer 29 of the first airbag 281 and then through the polishing layer 29 of the second airbag 282, thereby performing multiple polishing (the polishing layer 29 at the first airbag 281 is coarse polishing, and the polishing layer 29 at the second airbag 282 is fine polishing).

[0042] After the blank plate 7 is polished, the cylinder 5 rises, driving the inner mold head 62 to rise. At this time, the lower stabilizing seat 8 also moves upward under the action of the third spring 26, and the sliding plate 35 also moves upward under the action of the fourth spring 37. The upward movement of the sliding plate 35 will drive the drive rod 322 to move upward, and by driving the bidirectional lead screw 321 to reverse, the upper and lower pressing plates 30 will separate, allowing the airbag 28 to be retracted into the mold groove 27. In addition, during the upward movement of the inner stabilizing seat 82, the rack 41 and the gear 40 will drive the gear 40 to reverse, and the reverse movement of the gear 40 will... The engagement with the toothed part 39 causes the outer stabilizing seat 81 to move upward, which is equivalent to the inner stabilizing seat 82 moving upward, until the outer stabilizing seat 81 and the inner stabilizing seat 82 are flush. At the same time, the inner die head 62 will abut against the locking rod 91 during its upward movement, causing the locking rod 91 to move upward. After the locking rod 91 moves upward, it will disengage from the unlocking rod 17. After the insertion hole 11 and the sliding hole 10 are aligned, the locking rod 91 will be inserted into the insertion hole 11 under the action of the first spring 92, so that the inner die head 62 and the outer die head 61 are flush again, thus preparing for the next stamping.

[0043] See Figure 1A light steel keel assembly includes a trapezoidal keel 43, a square tube fixing seat 44, and a hanger 45. The trapezoidal keel 43 has an opening at the bottom, and the two sides of the opening are hook-shaped. The square tube fixing seat 44 has a first hook body on one side of the top opening that is installed in conjunction with the bottom of the trapezoidal keel 43, and a side extension hook 46 on the other side. The hanger 45 has a second hook body 47 on the top that is installed in conjunction with the bottom of the trapezoidal keel 43, and a slot 48 at the bottom for the side extension hook 46 to pass through.

[0044] During installation, first, fix the trapezoidal keel 43 at intervals on the upper part of the house. Then, slide the square tube fixing seat 44 into the bottom inner side of the trapezoidal keel 43 through the first hook body. Next, hook the hanger 45 into the bottom of the trapezoidal keel 43 through the second hook body 47 and move it to the side of the square tube fixing seat 44. After inserting the square tube (not shown in the figure) into the square tube fixing seat 44, insert the side extension hook 46 on one side of the square tube fixing seat 44 into the slot 48 of the hanger 45. Then, bend the side extension hook 46 downward to tighten the hanger 45 to complete the installation of one position. (For a schematic diagram of the keel assembly hanger, please refer to...)
