Description

Technical field:

[0001] The utility model relates to the technical field of protective door processing equipment, and more specifically to a long steel continuous punching device for protective doors. Background technology:

[0002] In some existing civil defense works or dangerous manufacturing environments, protective doors or explosion-proof doors are generally installed for protection. In the existing protective doors, except for the door panels made of integral steel plates, the frames and other parts are fixed by cutting and bending long steel plates. Before the bending process, the long steel plates need to be punched, and generally multiple holes need to be processed on the long steel plates.

[0003] The existing method is to manually place the long steel plate into the punching equipment for punching. After completing one punching, the long steel plate is moved. However, since it is a protective door, the thickness of the long steel plate is very thick, reaching 10 mm or even more than 10 mm, and its weight is heavy. Therefore, at least two people are needed to carry it when moving it. Each move requires two people to operate, and manual support is required during processing, which is inefficient and requires a large amount of manual labor. Utility model content:

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a device for continuously punching long steel plates for protective doors, which can automatically move the long plates for continuous punching without manual support, thus greatly reducing the amount of manual labor.

[0005] The solution of the utility model to solve the technical problem is:

[0009] A through hole is formed on the transversely placed plate directly below the punch of the punching main machine.

[0010] A guide sleeve is fixed to the bottom surface of the horizontally placed plate around the through hole, the bottom surface of the guide sleeve is fixed to the top surface of the top plate of the frame, and the middle through hole of the guide sleeve faces the middle through hole of the top plate of the frame. The guide sleeve can support the bottom surface of the middle part of the horizontally placed plate, ensuring that the surrounding parts are supported when the punch descends to punch the long plate.

[0011] Furthermore, a plurality of electromagnet blocks are fixed to the bottom surface of the transverse placement plate around the guide sleeve, and the elongated plate is adsorbed on the electromagnet blocks.

[0012] The electromagnet block is used to adsorb and fix the long plate.

[0013] Furthermore, the punching main machine includes a main frame, which is fixed on the top surface of the top plate of the frame, and is located behind the transversely placed plate. The front part of the upper fixed plate of the main frame is located above the middle part of the transversely placed plate. A stamping cylinder is fixed on the front top surface of the upper fixed plate of the main frame, and the bottom end of the push rod of the stamping cylinder extends out of the bottom surface of the upper fixed plate of the main frame and is fixed with a punch.

[0014] The rear lateral movement mechanism includes connecting plates fixed to the right and middle parts of the rear wall surface of the rear side baffle, and the two ends of the lateral movement screw are movably connected to the two connecting plates through bearings.

The upper horizontal plate is above the rear side baffle, and a pushing plate is fixed to the front bottom surface of the upper horizontal plate, and the rear wall surface of the pushing plate is close to the front wall surface of the rear side baffle.

[0015] The outstanding effects of the utility model are:

[0016] It can automatically move long plates for continuous punching without manual support. Except for loading, it requires two operations, and only one person is needed for subsequent operations, which greatly reduces manual labor and has high processing efficiency. Description of the drawings:

[0021] Furthermore, a plurality of support seats 11 are fixed to the left and right parts of the top surface of the top plate of the frame 10, a transverse placement plate 12 is fixed to the top surfaces of all the support seats 11 by bolts, a rear part of the top surface of the transverse placement plate 12 is fixedly connected to a rear baffle plate 13 by bolts, a front part of the top surface of the transverse placement plate 12 is formed with an elongated raised strip 121 extending upward, a long plate 100 to be processed is placed on the top surface of the transverse placement plate 12, a rear wall surface of the long plate 100 is close to a front wall surface of the rear baffle plate 13, a front wall surface of the long plate 100 is close to a rear wall surface of the elongated raised strip 21, and a top surface of the elongated raised strip 21 is lower than or slightly higher than a top surface of the long plate 100; the transverse placement plate 12 is in front of the main frame 22, and the punch 21 is located above the middle part of the transverse placement plate 12;

[0022] A rear lateral movement mechanism 30 is installed at the rear of the rear baffle 13; the rear lateral movement mechanism 30 includes a connecting plate 33 fixed to the right and middle parts of the rear wall of the rear baffle 13, and both ends of the lateral movement screw 34 are movably connected to the two connecting plates 33 through bearings, and a moving motor 35 is fixed to one of the connecting plates 33, and the output shaft of the moving motor 35 is a spline shaft, which is inserted into the spline hole at one end of the lateral movement screw 34 and drives the lateral movement screw 34 to rotate, and the moving block 31 is screwed on the lateral movement screw 34, and the top surface of the moving block 31 is fixed with an upper horizontal plate 311, and the upper horizontal plate 311 is above the rear baffle 13, and the front bottom surface of the upper horizontal plate 311 is fixed with a push plate 32, and the rear wall surface of the push plate 32 is close to the front wall surface of the rear baffle 13.

[0023] A rear transverse plate 36 extending left and right is fixed to the rear ends of the two connecting plates 33, a transverse guide strip 37 is fixed to the front wall surface of the rear transverse plate 36, a slider 312 is fixed to the rear wall surface of the moving block 31, and the transverse guide strip 37 is inserted into the rear guide groove formed at the rear end of the slider 312.

[0024] The middle connecting plate 33 is located at the left side behind the punch 21 .

[0025] Furthermore, a through hole 14 is formed on the transverse placement plate 12 just below the punch 21 of the punching main machine 20 .

[0026] A guide sleeve 15 is fixed to the bottom surface of the transverse placement plate 12 around the through hole 14 , the bottom surface of the guide sleeve 15 is fixed to the top surface of the top plate of the frame 10 , and the middle through hole of the guide sleeve 15 faces the middle through hole of the top plate of the frame 10 .

[0027] A plurality of electromagnet blocks 1 are fixed to the bottom surface of the transverse placement plate 12 around the guide sleeve 15 , and the elongated plate 100 is adsorbed on the electromagnet blocks 1 .

[0028] In this embodiment, the width between the front and rear of the transverse placement plate 12 is certain, so it is only suitable for one specification of long plates 100. When it is necessary to process a long plate 100 of another width, the original transverse placement plate 12 needs to be disassembled and replaced. Of course, the maximum width of the replaced transverse placement plate 12 is also limited. It is necessary to ensure that the through hole 14 of the replaced transverse placement plate 12 is directly below the punch 21. Therefore, the rear wall surface of the rear transverse moving mechanism 30 installed behind it must have a distance from the front wall surface of the lower part of the main frame 22 or just fit tightly to prevent interference and inability to install.

[0029] When the present embodiment is used, the long plate 10 is first placed on the top surface of the horizontal placement plate 12, with its rear wall surface close to the front wall surface of the rear side baffle 13, and the front wall surface of the long plate 100 is close to the rear wall surface of the long raised strip 21, so that the long plate 100 can still be moved left and right along the horizontal placement plate 12 under the condition of being limited;

[0030] Then, the moving motor 35 (which can be a servo motor) is operated to make the push plate 32 move to the left, and the elongated plate 10 is moved to the left so that the part to be processed is under the punch 21. Then, the moving motor 35 stops running, and the switch of the electromagnet block 1 is turned on, so that the electromagnet block 1 is turned on, thereby adsorbing and fixing the elongated plate 10 on the top surface of the horizontally placed plate 12. Then, the punch 21 is pushed by the push rod of the stamping cylinder 23 to quickly descend and punch the corresponding position of the elongated plate 10. After completion, the punched waste falls along the through hole 14 and the guide sleeve 15, and finally falls from the middle through hole on the top plate of the frame 10. A receiving bucket can be set below this position of the frame 10 to receive the waste, and the use effect is good.

[0031] After completion, the moving motor 35 is operated to move the elongated plate 100 to the left again, to the position required for subsequent processing and under the punch 21, and then it can be stopped and processed again. The processing effect is good and the efficiency is high, and it is suitable for continuous processing. After the entire elongated plate 100 is on the left side of the punch 21, the entire elongated plate 100 can be taken out and replaced with a new elongated plate 100 for processing, which is very convenient.

[0032] The electromagnet block 1 and the moving motor 35 in this embodiment are electrically connected to the control host through electrical connecting lines, and their operation is controlled by the control host, while the stamping cylinder 23 is connected to the hydraulic system through a connecting pipe. The related electric components of the hydraulic system, such as the oil pump, the solenoid valve, etc. are all electrically connected to the control host through electrical connecting lines, and their operation is controlled by the control host. They are all conventional structures and will not be described in detail here.
