Description

Technical Field

[0001] The utility model relates to the technical field of protective doors, in particular to a shearing machine for producing protective closed doors. Background Art

[0002] The protective sealed door is set at the outermost side of the entrance and exit, and has the dual functions of blocking shock waves and isolating toxic agents.

[0003] During the production process of protective closed doors, the door panels need to be cut according to demand. Workers need to place the door panels on the conveyor, which transports the door panels to the shearing machine, and then the shearing machine cuts the door panels. The cut door panels are then transported to the next processing position via the conveyor.

[0004] When the shearing machine cuts the door panel, the door panel needs to be aligned with the shearing machine. In the prior art, the alignment is mainly performed manually by workers, which is laborious and takes a lot of time. Each time the shearing machine cuts, the worker needs to manually measure the cutting distance, which prolongs the cutting time and reduces the cutting efficiency. Utility Model Content

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figure 1 to Figure 2 As shown, a shearing machine for producing protective closed doors includes a base 1, a first conveyor 2 and a second conveyor 3 are respectively provided on both sides of the base 1, a blanking plate 17 is hinged at one end of the second conveyor 3, a bracket 4 is provided on the base 1, a cutter 5 is provided on the bracket 4, a cutting groove 13 is provided on the base 1 below the cutter 5, a hydraulic cylinder 6 for driving the cutter 5 to rise and fall is fixedly connected to the bracket 4, a slide plate 7 correspondingly arranged on both sides is slidably connected to the first conveyor 2, and sliders 8 are fixedly connected at both ends of the slide plate 7, and the first conveyor 2 is provided with a plurality of slides 8. A conveyor 2 is provided with a slide groove 9 that cooperates with the slider 8. A bidirectional screw 10 that drives the sliders 8 on both sides to move toward each other is slidably connected in the slide groove 9. A motor 11 that drives the bidirectional screw 10 to rotate is fixedly connected to one side of the first conveyor 2. The door panel is transported to the bottom of the cutter 5 through the first conveyor 2, and the bidirectional screw 10 is driven to rotate by the motor 11, so that the slides 7 on both sides of the bidirectional screw 10 move toward each other, thereby controlling the door panel to be in the middle position of the first conveyor 2, and the cutter 5 is driven to move by the hydraulic cylinder 6 to shear the door panel.

[0023] like Figures 2 to 4 As shown, an H-shaped plate 12 is fixedly connected to the output shaft of the hydraulic cylinder 6, and the width of the H-shaped plate 12 is greater than the width of the cutter 5. The H-shaped plate 12 is movably plugged with at least one adjusting column 14, and both ends of the adjusting column 14 are fixedly connected to limit columns 15. A spring 16 is fixedly connected between the bottom surface of the H-shaped plate 12 and the limit column 15 at the lower end of the adjusting column 14. A connecting plate 18 is slidably connected to one side of the second conveyor 3 on the base 1, and first electric push rods 19 that drive the connecting plate 18 to slide are fixedly connected on both sides of the bracket 4. A discharge hole 20 is provided on the connecting plate 18. Slots 21 are provided on 18 at both ends of the discharge hole 20, and baffles 22 are movably inserted in the slots 21. One end of the connecting plate 18 is fixedly connected to a second electric push rod 23 for driving the baffle 22 to move. By starting the hydraulic cylinder 6, the H-shaped plate 12 moves downward and contacts the door panel first, thereby fixing the door panel. Through the action of the spring 16 and the adjusting column 14, door panels of different thicknesses can be fixed. The connecting plate 18 is pushed to move by the first electric push rod 19 to determine the shear distance, and the baffle 22 is pushed to move by the second electric push rod 23 to block and pass the door panel.

[0024] In specific use, the door panel is placed on the first conveyor 2, and then the two motors 11 are started at the same time. The motor 11 drives the bidirectional screw 10 to rotate, and the bidirectional screw 10 drives the two slides 7 located on both sides of the first conveyor 2 to move toward each other, so as to correct the door panel and fix the door panel in the middle position of the first conveyor 2, and then the motor 11 is started in the reverse direction. At this time, the motor 11 drives the bidirectional screw 10 to rotate in the reverse direction, and the two slides 7 return to both sides of the first conveyor 2, and then the two first electric push rods 19 are started at the same time. The first electric push rod 19 drives the connecting plate 18 to move, and stops when it moves to the appropriate position. At this time, it moves to the shear distance, and starts the two second electric push rods 23 at the same time. The output end of the second electric push rod 23 drives the baffle 22 to move, so that the baffle 22 enters the discharge hole 20, moves to the appropriate position and stops, and then starts the first conveyor 2. The first conveyor 2 conveys the door panel to the base 1, and then the door panel moves until one end is against the side of the baffle 22. At this time, the hydraulic cylinder 6 is started, and the hydraulic cylinder 6 drives the cutter 5 and the H-shaped plate 12 to move downward. The limit column 15 at one end of the adjustment column 14 contacts the door panel first and fixes it. At this time, the limit column 15 squeezes the spring 16 to deform the spring 16. The spring 16 generates a downward thrust, so that the door panel is fixed tighter. Then the cutter 5 shears the door panel. After shearing, the two second electric push rods 23 are started at the same time. The second electric push rods 23 drive the baffle 22 to return to the initial position, and the second conveyor 3 is started. The second conveyor 3 drives the door panel to move. The door panel passes through the discharge hole 20 and then discharges from the discharge plate 17. When the shearing size needs to be changed, it is only necessary to start the two first electric push rods 19 at the same time and adjust the distance between the connecting plates 18.
