Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of roll forming machines, specifically a roll forming machine for the production of security doors. Background Technology
[0002] A roll forming machine for security door production is an auxiliary device used to roll the required parts of security doors to the corresponding thickness. It is widely used in the field of roll forming production. By placing stainless steel or aluminum alloy raw materials between the upper and lower rollers and pushing them inward, the relative rotation direction of the upper and lower rollers can be used to bring the raw materials into the space between the upper and lower rollers, roll forming the raw materials, and obtaining the finished product from the rear end.
[0003] In the existing technology, after long-term use and observation, it has been found that the gap between the upper and lower rollers of the roll forming machine used in the production of security doors is fixed, which can only roll form a certain thickness and cannot meet the process requirements of more thickness models. Moreover, during roll forming, the impurities attached to the raw material will be pressed onto the surface of the raw material under the rolling of the upper and lower rollers and are difficult to clean. If it is a hard impurity such as metal shavings, it may even damage the raw material and affect the quality of the finished product.
[0004] Therefore, this utility model provides a roll forming machine for the production of security doors. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a roll forming machine for the production of security doors.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A roll forming machine for producing anti-theft doors, comprising an operating frame, two lower pressure rollers rotatably connected between the two sides of the inner surface of the operating frame, a first mounting frame fixedly connected to the top of the operating frame, two first sliding grooves on both sides of the surface of the first mounting frame, pressure roller mounting frames slidably connected to the inner sidewalls of the two sets of first sliding grooves, two upper pressure rollers rotatably connected between the two sides of the inner surface of the two pressure roller mounting frames, and a drive assembly for controlling the lifting and lowering of the two pressure roller mounting frames provided at the top of the first mounting frame. A second mounting bracket is fixedly connected to one side of a mounting bracket. The second mounting bracket has second sliding grooves on both sides of its surface. A sweeping roller mounting bracket is slidably connected to the inner sidewalls of the two second sliding grooves. An upper sweeping roller is rotatably connected between the two sides of the inner surface of the sweeping roller mounting bracket. A lower sweeping roller is provided below the upper sweeping roller. The two ends of the lower sweeping roller are rotatably connected to the two sides of the inner surface of the operating frame, respectively. A cylinder is fixedly installed on the top of the second mounting bracket. The output end of the cylinder extends through to the bottom of the second mounting bracket and is fixedly connected to the top of the sweeping roller mounting bracket. The output end of the cylinder drives the sweeping roller mounting bracket to move up and down, which can adjust the gap between the upper and lower sweeping rollers.
[0007] Preferably, the drive assembly includes two lead screws, which are respectively fixedly connected to the top of two pressure roller mounting frames. The top ends of the two lead screws extend through to the top of the first mounting frame. Two worm gears are threadedly connected to the outside of the two lead screws. The bottom of the two worm gears is rotatably connected to the top of the first mounting frame. A rotating shaft is provided on one side of the surface of the two worm gears. Two worms are fixedly connected to the outside of the rotating shafts. The two worms are respectively meshed with the two worm gears. As the two worm gears rotate, the two lead screws drive the two pressure roller mounting frames and the upper pressure roller to move up and down synchronously, which can adjust the gap between the two upper pressure rollers and the two lower pressure rollers.
[0008] Preferably, a protective shell is fixedly connected to the top of the first mounting bracket. The protective shell is sleeved on the outside of the two worm gears and the two worms. A third motor is fixedly installed on one side of the surface of the protective shell. The output end of the third motor extends through into the inside of the protective shell and is fixedly connected to one end of the rotating shaft. The other end of the rotating shaft is rotatably connected to one side of the inner surface of the protective shell. The output end of the third motor drives the rotating shaft to rotate, so that the two worms mesh with the two worm gears for transmission.
[0009] Preferably, multiple rollers are rotatably connected between the two sides of the inner surface of the operating frame. The upper edges of the multiple rollers are flush with the upper edges of the two lower pressure rollers. When the raw material is placed on the rollers, it is easier to push it between the upper and lower pressure rollers.
[0010] Preferably, a first reducer is fixedly installed on one side of the surface of one of the pressure roller mounting frames, a first motor is fixedly installed on one side of the surface of the first reducer, and the output end of the first reducer extends through into the interior of the pressure roller mounting frame and is fixedly connected to one end of the upper pressure roller. A second reducer is fixedly installed on one side of the surface of the operating frame, a second motor is fixedly installed on one side of the surface of the second reducer, and the output end of the second reducer extends through into the interior of the operating frame and is fixedly connected to one end of one of the lower pressure rollers.
[0011] Preferably, one end of each of the two upper pressure rollers extends through to the outside of the pressure roller mounting frame and is fixedly connected to two first synchronous pulleys. A first synchronous belt is fitted around the outside of the two first synchronous pulleys. One end of each of the two lower pressure rollers extends through to the outside of the operating frame and is fixedly connected to two second synchronous pulleys. A second synchronous belt is fitted around the outside of the two second synchronous pulleys. This allows the two lower pressure rollers and the two upper pressure rollers to rotate synchronously.
[0012] Preferably, the bottom of the operating frame is fixedly connected with multiple support legs for support.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The roll forming machine for producing security doors described in this utility model is equipped with components such as lead screws, worm gears, worms, and pressure roller mounting frames. The rotating shaft drives the worm gear to mesh with the worm wheel for transmission. The two lead screws drive the two pressure roller mounting frames and the upper pressure roller to move up and down synchronously as the two worm wheels rotate. The gap between the upper and lower pressure rollers can be adjusted. Compared with the prior art, it can be applied to the roll forming process requirements of different thickness models and is more practical.
[0015] 2. The roll forming machine for producing security doors described in this utility model, by setting up components such as cylinders, sweeping roller mounting frames, and upper sweeping rollers, uses upper and lower sweeping rollers to clean the surface of the raw material before roll forming, removing impurities and preventing the upper and lower pressure rollers from pressing impurities from the surface of the raw material onto the surface of the finished product. This can prevent metal shavings and other impurities from damaging the surface during the roll forming process, thus ensuring the quality of the finished product. Attached Figure Description
