[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figure 1-12In this embodiment of the present invention, a door frame forming and die-cutting device for fire door production includes a mounting base 1, with a winding unwinding mechanism 4 fixed above one end of the mounting base 1; a base box 2 is provided on one side of the winding unwinding mechanism 4; a tensioning component 5 and a flattening roller 6 are installed on the top of the base box 2, and a die-cutting component 3 is provided on the outside of the flattening roller 6; a transmission component 7 is provided on the side of the die-cutting component 3 away from the flattening roller 6; and a machine housing 8 is also provided on the mounting base 1.

[0044] By adopting the above technical solution, during use, the uncoiling mechanism 4 uncoils the cold-rolled steel sheet. After uncoiling, the cold-rolled steel sheet enters the tensioning assembly 5 for tensioning. The tensioning method eliminates the elastic curling of the steel sheet and ensures the normal transmission of the steel sheet. Then, the steel sheet is leveled by multiple flattening rollers 6. After the steel sheet is leveled, it enters the die-cutting assembly 3 for die-cutting. The die-cutting assembly 3 is used to groove the steel sheet. After die-cutting, the steel sheet is transmitted out by the conveying assembly 7, which facilitates subsequent cutting, bending or stamping.

[0045] In this embodiment, the unwinding mechanism 4 includes a base frame 41, on which a bracket 42 is fixed; an unwinding motor 43 is fixed on the bracket 42, and a synchronous pulley 44 is mounted on the output shaft of the unwinding motor 43; the synchronous pulley 44 is connected to another synchronous pulley 44 mounted on a transmission shaft 46 via a synchronous belt 45.

[0046] The drive shaft 46 is connected to the unwinding shaft of the steel coil via a coupling; the other end of the unwinding shaft is connected to the quick-connect assembly 48. The quick-connect assembly 48 is fixed to the brake assembly 47; two brake assemblies 47 are provided, respectively located at both ends of the unwinding shaft.

[0047] By adopting the above technical solution, during uncoiling, one end of the uncoiling shaft of the coiled cold-rolled steel sheet is first connected to the drive shaft 46 through a coupling, and the other end is installed in the quick-clamping assembly 48. After the cold-rolled steel sheet is installed, one end of the cold-rolled steel sheet is pulled out. During normal operation, the uncoiling motor 43 drives the drive shaft 46 to rotate with the cooperation of the synchronous pulley 44 and the synchronous belt 45, thus realizing the uncoiling of the steel sheet coil.

[0048] In this embodiment, the brake assembly 47 includes a gantry frame 471, a slide rail 472 is fixed inside the gantry frame 471, and a slide frame 473 is slidably connected on the slide rail 472; a brake wheel 475 is connected to one side of the slide frame 473 via a rotating shaft; the slide frame 473 is also connected to a tension cylinder 55 fixed on the gantry frame 471.

[0049] By adopting the above technical solution, when an emergency stop is required, the cylinder rod of the brake cylinder 474 extends, driving the slide 473, which is equipped with the brake wheel 475, to slide downward along the slide rail 472, so that the brake wheel 475 is tightly fitted with the drive shaft 46, and in conjunction with the deceleration or shutdown of the unwinding motor 43, the drive shaft 46 is braked, so that the steel coil stops unwinding.

[0050] In this embodiment, the quick-connect assembly 48 includes a fixed base 482, one end of which is movably connected to a locking seat 481 via a rotating shaft, and the other end is detachably connected to the locking seat 481 via a locking bolt 483.

[0051] By adopting the above technical solution, when a new steel coil needs to be replaced, the locking bolt 483 is rotated to separate the locking seat 481 from the fixed base 482, and then the locking seat 481 is flipped to one side to facilitate the removal of the unwinding shaft.

[0052] In this embodiment, the tensioning assembly 5 includes a first horizontal roller 51 and a second horizontal roller 52 disposed on the top of the base box 2; the two ends of the first horizontal roller 51 and the second horizontal roller 52 are connected to the base box 2 through bearing seats.

[0053] A tensioning roller 53 is provided below the middle position of the first horizontal roller 51 and the second horizontal roller 52; the two ends of the tensioning roller 53 are connected to the U-shaped frame 54 through bearings; the U-shaped frame 54 is fixed on the cylinder rod of the tensioning cylinder 55.

[0054] By adopting the above technical solution, when tensioning the steel coil, the steel plate is first passed around the first horizontal roller 51, the tensioning roller 53 and the second horizontal roller 52 in sequence. When the cylinder rod of the tensioning cylinder 55 extends or retracts, the tension adjustment of the steel plate can be achieved.

[0055] In this embodiment, the transmission component 7 includes two side plates 71, a transmission roller 73 is provided between the two side plates 71, and one end of the transmission roller 73 is externally connected to the transmission motor 74.

[0056] Two pressing rollers 72 are also provided between the two side uprights 71, and the two ends of the two pressing rollers 72 are connected to the side uprights 71 through bearings.

[0057] By adopting the above technical solution, after the steel plate is die-cut, the steel plate passes around two pressing rollers 72 and transmission rollers 73. The transmission motor 74 drives the transmission rollers 73 to rotate, thereby transferring the steel plate to the next process.

[0058] In this embodiment, the die-cutting assembly 3 includes a base 31, and a die-cutting bottom die 32 is fixed on the top of the base 31; a die-cutting top die 33 is installed above the die-cutting bottom die 32; the die-cutting top die 33 is fixed to the cylinder rods of a plurality of die-cutting cylinders 34; and the die-cutting cylinders 34 are fixed to the machine housing 8.

[0059] By adopting the above technical solution, when the steel plate passes through the die-cutting bottom die 32 and the die-cutting upper die 33, the cylinder rod of the die-cutting cylinder 34 extends, causing the die-cutting upper die 33 to move down. When the die-cutting upper die 33 and the die-cutting bottom die 32 are closed, the die-cutting of the steel plate can be realized. The die-cutting bottom die 32 is fixed on the base 31, and a discharge port 35 is reserved inside the base 31. The metal scrap that has been die-cut is discharged from the discharge port 35.

[0060] The working principle of this utility model is as follows: In use, one end of the unwinding shaft of the coiled cold-rolled steel sheet is first connected to the drive shaft 46 via a coupling, and the other end is installed in the quick-connect assembly 48. After the cold-rolled steel sheet is installed, one end of the cold-rolled steel sheet is pulled out. During normal operation, the unwinding motor 43 drives the drive shaft 46 to rotate under the cooperation of the synchronous pulley 44 and the synchronous belt 45, thus realizing the unwinding of the steel sheet coil. When tensioning the steel coil, the steel sheet is first passed sequentially over the first horizontal roller 51, the tensioning roller 53, and the second horizontal roller 52. When the cylinder rod of the tensioning cylinder 55 extends or retracts, the tension of the steel plate can be adjusted. Tensioning eliminates the elastic curling of the steel plate, ensuring its normal transport. Then, the steel plate is leveled by multiple flattening rollers 6. After leveling, the steel plate enters the die-cutting assembly 3 for die-cutting. The cylinder rod of the die-cutting cylinder 34 extends, causing the upper die-cutting mold 33 to move downwards. When the upper die-cutting mold 33 and the lower die-cutting mold 32 close, the steel plate is die-cut and formed. The steel plate is die-cut using die-cutting molds, and the position and size of each groove are relatively precise.

[0061] After the steel plate is die-cut, it passes over two pressing rollers 72 and a transmission roller 73. The transmission motor 74 drives the transmission roller 73 to rotate, thus transferring the steel plate to the next process.

[0062] When a new steel coil needs to be replaced, the locking seat 481 is separated from the fixed base 482 by rotating the locking bolt 483, and then the locking seat 481 is flipped to one side to facilitate the removal of the unwinding shaft.

[0063] It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that it is made possible without departing from the spirit or essential characteristics of this invention.

[0064] In this case, the present invention can be implemented in other specific forms. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
