Description

Technical Field

[0001] The utility model relates to the technical field of iron tower part processing, in particular to a punching device for iron tower part processing. Background Art

[0002] Iron towers play an important role in power transmission. There are many types of existing iron towers, among which the most common are angle iron towers and steel pipe towers. When building iron towers, some structures use bolt connections. When making bolt connections, hole punching treatment needs to be carried out in advance, that is, a punching device for iron tower part processing needs to be used.

[0003] However, in the prior art, angle iron towers are built with angle steel. Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other at an angle. When the existing punching device for iron tower parts punches angle steel, it cannot punch the two sides of the angle steel simultaneously. It can only punch one side of the angle steel first, and then change the fixed position of the angle steel to turn it over, which is very inconvenient and requires a lot of labor, greatly reducing the punching efficiency of the punching device for iron tower parts. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A punching device for iron tower part processing, comprising: an operating table, an angle steel body, and two punching motors.

[0008] As a preferred embodiment, threaded lead screws are threadedly connected to one side surface of each of the plurality of U-shaped plates. A turntable is fixedly installed on one end surface of each of the plurality of threaded lead screws. The other end surface of each of the plurality of threaded lead screws is connected to a fixed plate through a bearing. Anti-slip strips are fixedly installed on the bottom surface of each of the plurality of fixed plates.

[0009] As a preferred embodiment, two vertical rods are fixedly installed on the top surface of each of the plurality of fixed plates. Every two of the plurality of vertical rods form a group.

One end of each group of vertical rods away from the corresponding fixed plate correspondingly passes through the inner wall surface of one side of the plurality of U-shaped plates in a movable manner. A circular plate is fixedly installed on the top surface of each of the plurality of vertical rods.

[0010] As a preferred embodiment, the adjusting assembly includes two second through grooves. The two second through grooves are opened on the other two sides of the top surface of the operating table. Cross bars are fixedly installed between the inner wall surfaces at both ends of the two second through grooves. Sliders are movably sleeved on the surfaces of the two cross bars. The two side surfaces of each of the two sliders are correspondingly and movably attached to the two side inner walls of the two second through grooves. Electric push rods are fixedly installed on the top surface of each of the two sliders. L-shaped plates are fixedly installed at the output ends of the two electric push rods. Two sliding rods are fixedly installed on the bottom surface of each of the two L-shaped plates. A slide plate is slidably connected between every two of the plurality of sliding rods. Two punching motors are fixedly installed on the bottom surface of the two slide plates. Punching heads are fixedly installed at the output ends of the two punching motors. Air cylinders are fixedly installed on the top surface of each of the two L-shaped plates.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In this utility model, when punching angle steel with a punching device for processing iron tower parts, when it is necessary to fix the angle steel body, first rotate multiple turntables. The rotation of the multiple turntables drives the rotation of multiple threaded lead screws. The rotation of the multiple threaded lead screws drives the movement of multiple fixing plates. The rotation of the multiple fixing plates drives the movement of multiple vertical rods. When the distance between the inner wall surfaces of the multiple fixing plates and one side of the multiple U-shaped plates is greater than the thickness of the angle steel body, at this time, two first motors are operated through the control terminal. The operation of the two first motors drives the rotation of two bidirectional threaded rods. The rotation of the two bidirectional threaded rods drives multiple movable blocks to move in opposite directions in groups of two. The movement of the multiple movable blocks in groups of two in opposite directions drives the multiple U-shaped plates to move in opposite directions in groups of two. When the inner wall surfaces of one side of the multiple U-shaped plates in groups of two can all fit the two inner wall surfaces of the angle steel body, at this time, place the angle steel body inside the multiple U-shaped plates. Subsequently, reverse-rotate the multiple turntables. When the multiple fixing plates can cooperate with the inner wall surfaces of one side of the multiple U-shaped plates to firmly clamp and fix the angle steel body, then the turntables can be released, thereby achieving the purpose of fixing the angle steel body. Subsequently, the punching motor can be started to perform punching treatment on both surface sides of the angle steel body simultaneously. Through the cooperation of the above structures, the distance between the multiple U-shaped plates can be adjusted to adapt to angle steel bodies of different models. At the same time, the fixing plates cooperate with the U-shaped plates to clamp and fix angle steel bodies of different thicknesses. By horizontally fixing the angle steel body and placing the outer wall surfaces of both sides of the angle steel body at 45 degrees, it is convenient to perform punching treatment on the outer wall surfaces of both sides of the angle steel body simultaneously, reducing the required labor force and improving the punching efficiency of the punching device for processing iron tower parts.

[0014] 2. In this utility model, when it is necessary to adjust the position of the punching motor, first fix the angle steel body through the fixing component. Subsequently, two second motors are operated through the control terminal. The operation of the two second motors drives the rotation of two rotating shafts. The rotation of the two rotating shafts drives the rotation of two gears. The two gears rotate and mesh with two racks, so that the two sliders slide on the surfaces of the two cross bars. The sliding of the two sliders on the surfaces of the two cross bars drives the movement of two electric push rods, thereby driving the horizontal movement of the two punching motors. When the two punching motors reach the horizontal punching position, at this time, stop operating the two second motors and start the two electric push rods. The two electric push rods drive the two punching motors to move vertically. When the punching motors reach the appropriate distance, at this time, operate the two cylinders and the two punching motors. The operation of the two cylinders drives the two sliding plates to move on the surfaces of multiple sliding rods. The movement of the two sliding plates drives the two punching motors to move obliquely downward. The two punching motors drive the two punching heads to rotate to perform punching treatment on the angle steel body. Through the cooperation of the above structures, after the angle steel body is fixed, only by adjusting the position of the punching motor can punching be performed on different positions of the angle steel, without moving the angle steel body, relatively reducing the consumption of resources.

[0033] Specifically: The multiple vertical rods 511 function to ensure the stable movement of the multiple fixed plates 510.

[0034] In one embodiment, the adjusting assembly 6 includes two second through grooves 601. The two second through grooves 601 are opened on the other two sides of the top surface of the operating table 1. Cross bars 602 are fixedly installed between the inner wall surfaces at both ends of each of the two second through grooves 601. Sliders 603 are movably sleeved on the surfaces of the two cross bars 602. The two side surfaces of each of the two sliders 603 are correspondingly in movable contact with the two inner wall surfaces of the two second through grooves 601. Electric push rods 604 are fixedly installed on the top surface of each of the two sliders 603. L-shaped plates 605 are fixedly installed at the output ends of the two electric push rods 604. Two sliding rods 610 are fixedly installed on the bottom surface of each of the two L-shaped plates 605. A sliding plate 611 is slidably connected between every two of the multiple sliding rods 610. Two punching motors 7 are fixedly installed on the bottom surface of the two sliding plates 611. Punching heads 701 are fixedly installed at the output ends of the two punching motors 7. Cylinders 612 are fixedly installed on the top surface of each of the two L-shaped plates 605. The output ends of the two cylinders 612 pass through the two L-shaped plates 605 movably and are fixedly connected to one end of the two sliding plates 611.

[0035] Specifically: The electric push rod 604 functions to drive the punching motor 7 to move vertically. The punching motor 7 is an existing device and can drive the punching head 701 to rotate for punching. The cylinder 612 functions to drive the punching motor 7 to move obliquely downward. A limiting plate is fixedly installed on one end surface of each of the multiple sliding rods 610 to prevent the two sliding plates 611 from detaching from the multiple sliding rods 610.

[0036] In one embodiment, a rotating shaft 606 is connected through bearings on one side surface of each of the two sliders 603. A second motor 607 is fixedly installed on the other side surface of each of the two sliders 603. The output ends of the two second motors 607 and one end of each of the two rotating shafts 606 are fixedly connected correspondingly. A gear 608 is fixedly sleeved on the surface of each of the two rotating shafts 606. Two racks 609 are fixedly installed at both ends of the bottom surface of the operating table 1. The two racks 609 and the two gears 608 are correspondingly meshed with each other.

[0037] Specifically: The two second motors 607 are both forward and reverse motors. The gears 608 and the racks 609 function to drive the sliders 603 to slide on the surface of the cross bar 602. When the sliders 603 move to the extreme ends of the cross bar 602, the gears 608 are always meshed with the racks 609.

[0038] Working principle: When using the punching device for processing iron tower parts to punch the angle steel, when it is necessary to fix the angle steel body 2, first rotate multiple turntables 509. The rotation of multiple turntables 509 drives the rotation of multiple threaded lead screws 508. The rotation of multiple threaded lead screws 508 drives the movement of multiple fixing plates 510. The rotation of multiple fixing plates 510 drives the movement of multiple vertical rods 511. When the distance between the inner wall surfaces of multiple fixing plates 510 and one side of multiple U-shaped plates 507 is greater than the thickness of the angle steel body 2, at this time, the control terminal 4 operates two first motors 503. The operation of two first motors 503 drives the rotation of two bidirectional threaded rods 502. The rotation of two bidirectional threaded rods 502 drives multiple movable blocks 504 to move in opposite directions in groups of two. The movement of multiple movable blocks 504 in opposite directions in groups of two drives multiple U-shaped plates 507 to move in opposite directions in groups of two. When the inner wall surfaces of one side of multiple U-shaped plates 507 in groups of two can all fit the two inner wall surfaces of the angle steel body 2, at this time, place the angle steel body 2 inside multiple U-shaped plates 507. Then rotate multiple turntables 509 in the reverse direction. When multiple fixing plates 510 can cooperate with the inner wall surface of multiple U-shaped plates 507 to firmly clamp and fix the angle steel body 2, the turntables 509 can be released, thus achieving the purpose of fixing the angle steel body 2. Subsequently, the punching motor 7 can be started to punch the two side surfaces of the angle steel body 2 simultaneously. Through the cooperation of the above structure, the distance between multiple U-shaped plates 507 can be adjusted to adapt to angle steel bodies 2 of different models. At the same time, the fixing plate 510 cooperates with the U-shaped plate 507 to clamp and fix angle steel bodies 2 of different thicknesses. By horizontally fixing the angle steel body 2 and placing the two outer wall surfaces of the angle steel body 2 at a 45-degree angle, it is convenient to punch the two outer wall surfaces of the angle steel body 2 simultaneously, reducing the required labor force and improving the punching efficiency of the punching device for processing iron tower parts;When it is necessary to adjust the position of the punching motor 7, first fix the angle steel body 2 through the fixing component 5, and then operate two second motors 607 through the control terminal 4. The operation of the two second motors 607 drives the rotation of two rotating shafts 606. The rotation of the two rotating shafts 606 drives the rotation of two gears 608. The rotation of the two gears 608 meshes with two racks 609, so that the two sliders 603 slide on the surfaces of the two cross bars 602. The sliding of the two sliders 603 on the surfaces of the two cross bars 602 drives the movement of two electric push rods 604, thereby driving the lateral movement of the two punching motors 7. When the two punching motors 7 reach the lateral punching position, stop the operation of the two second motors 607 and start the two electric push rods 604 at this time. The two electric push rods 604 drive the vertical movement of the two punching motors 7. When the punching motor 7 reaches the appropriate distance, operate the two cylinders 612 and the two punching motors 7 at this time. The operation of the two cylinders 612 drives the movement of two sliding plates 611 on the surfaces of multiple sliding rods 610. The movement of the two sliding plates 611 drives the two punching motors 7 to move obliquely downward. The two punching motors 7 drive the two punching heads 701 to rotate and punch the angle steel body 2. Through the cooperation of the above structure, after the angle steel body 2 is fixed, only the position of the punching motor 7 needs to be adjusted to punch different positions of the angle steel, without moving the angle steel body 2, relatively reducing the consumption of resources.

[0039] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
