Description

Technical Field

[0001] The invention relates to the technical field of steel beam processing, and in particular to a processing device and method for heavy assembled steel beams. Background Art

[0002] Heavy steel beams are the most commonly used materials in the construction industry. They are large in size and weight. Steel beams include I-shaped steel, I-shaped steel, U-shaped steel, etc., among which I-shaped steel is more widely used. When assembling steel beams, it is generally necessary to open assembly holes on the steel beams. At this time, corresponding processing equipment is required to punch holes in the steel beams. Traditional punching methods mostly use large handheld punching machines for punching. Due to the large mass of steel beams, handheld punching is time-consuming and labor-intensive, and consumes a lot of physical strength. Therefore, existing steel beam punching methods mostly use automated or semi-automated punching equipment for operation.

[0003] After searching, the Chinese invention patent with publication number CN117862887B discloses an end punching machine for automated processing of construction steel beams, which has two marking pens connected to the guide plate below by horizontal sliding. The two marking pens correspond to the two punching machines respectively, and the marking pens can mark the punching position of the other end face of the steel beam (the steel beam is I-shaped); although the above-mentioned processing equipment is provided with a marking pen to mark the punching position in order to improve its punching accuracy, in the actual operation process, since the marking pen is installed inside the fixed seat and the marked position is the inner bottom of the I-shaped steel beam, although it has the marking function, the marked position is not easy for the staff to check, so that the punching position calibration work cannot be carried out. Moreover, after the punching position calibration, it lacks the function of being moved away, resulting in the marking pen easily interfering with the punching path during punching, and the end of the punching machine easily damaging the marking pen.

When the two touch frames move downward until they are in contact with the top of the driving plate, their continuous downward movement can squeeze the driving plate downward, thereby causing the two U-shaped plates to move in relative directions, and then the two sides of the steel beam body are tightened by two groups of tightening blocks, thereby forming a synchronous tightening work of the steel beam body, having a good linkage function, and no need to set up a separate electric drive source for operation, thereby improving the synchronization of the processing operation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1:

[0046] The electric conveying assembly 3 includes two conveying rollers for horizontally conveying the steel beam body 2 and a motor for rotationally driving one of the conveying rollers. The two conveying rollers are connected by a sprocket so that the two conveying rollers rotate synchronously in the same direction, thereby performing horizontal conveying and adjustment of the steel beam body 2.

[0047] The fixing mechanism 5 is provided to fix the steel beam body 2 during the processing, thereby ensuring its stability during the drilling process;

[0048] The processing mechanism 6 is used to perform drilling processing on the steel beam body 2 after being tightly fixed;

[0049] The processing mechanism 6 includes an H-shaped bracket 61 fixed to the top of the processing table 1, and a crossbeam 62 is fixedly connected to one side of the H-shaped bracket 61. A punch body 63 and a driving assembly 64 for driving the punch body 63 up and down and forward and backward are arranged on the crossbeam 62. A calibration assembly 65 for calibrating the punching position is arranged on the H-shaped bracket 61;

[0050] By setting the driving component 64 in the processing mechanism 6, not only can the punching machine body 63 be driven to adjust up and down, but also the position of the punching machine body 63 can be adjusted longitudinally, so as to meet the punching machine body 63 better matching the punching position of the steel beam body 2. By setting the calibration component 65 in the processing mechanism 6, not only can the punching position of the steel beam body 2 be marked, but also the punching position of the steel beam body 2 can be calibrated synchronously, so as to improve the accuracy of its subsequent punching processing. During the punching operation, the calibration component 65 will automatically shrink, which effectively prevents the calibration component 65 from interfering with the punching trajectory, so as to improve the convenience of the punching processing.

[0051] See attached Figures 3 to 5 The driving assembly 64 includes two guide rods 641 slidably connected to the interior of the crossbeam frame 62, a connecting plate 642 is fixedly connected between the bottom ends of the two guide rods 641, and an electric telescopic rod 643 for driving the connecting plate 642 up and down is fixedly connected to the top of the crossbeam frame 62;

[0052] The electric telescopic rod 643 is connected to the external power supply and control system, and is used to drive the connecting plate 642 to move up and down. Through the up and down movement of the connecting plate 642, the height of the position of the punching machine body 63 is adjusted to form a punching calibration and storage work. The two guide rods 641 are set to improve the smoothness of the up and down movement of the connecting plate 642.

[0053] See attached Figure 4 and Figure 5 , an electric guide rail 644 is fixedly installed at the bottom of the connecting plate 642, and the punch body 63 is fixedly installed at the driving end of the electric guide rail 644;

[0054] The electric guide rail 644 adopts the electric guide rail mechanism in the prior art, which is used to drive the punching machine body 63 to perform longitudinal adjustment, thereby satisfying the punching processing at different positions of the steel beam body 2;

[0055] The punch body 63 includes a drill bit that is rotationally driven by an electric motor and an electric cylinder for feeding the motor and the drill bit downward;

[0056] The electric cylinder is used to drive the motor and the drill bit to move up and down to form a drilling and feeding operation. The motor drives the drill bit to rotate, thereby forming a drilling process for the steel beam body 2.

[0057] See attached Figures 5 to 8 The calibration assembly 65 includes a movable rod 651 slidably connected to the front of the H-shaped bracket 61 through a reinforcing beam, one end of the movable rod 651 is fixedly connected to a U-shaped frame 652, the interior of the U-shaped frame 652 is fixedly connected to a longitudinal axis 653, and the outer surface of the longitudinal axis 653 is slidably connected to an L-shaped connecting rod 654 through a collar, and the bottom end of the L-shaped connecting rod 654 is connected to an identification member 658;

[0058] The movable rod 651 is slidably connected to the front of the H-shaped bracket 61 by a reinforcing beam, so as to facilitate the horizontal installation of the identification member 658. The longitudinal axis 653 is set and the L-shaped connecting rod 654 is slidably connected to the outer surface of the longitudinal axis 653 by a collar, so as to facilitate the longitudinal adjustment of the identification member 658.

[0059] The marking end of the marking member 658 coincides with the vertical line of the drill bit of the punch body 63, so that when the punching position is marked by the marking member 658, the punching end of the punch body 63 coincides with the punching position;

[0060] The driving end of the electric guide rail 644 is fixedly connected with an L-shaped guide plate 655, and the bottom of the L-shaped guide plate 655 is slidably connected with a transverse shaft 656 through a sleeve frame. The transverse shaft 656 passes through the L-shaped connecting rod 654, and the L-shaped connecting rod 654 is slidably connected to the transverse shaft 656;

[0061] The L-shaped guide plate 655 is connected to the driving end of the electric guide rail 644, and the L-shaped guide plate 655 is slidably connected to the L-shaped connecting rod 654 through the transverse shaft 656, so that the calibration component 65 synchronously follows the punch body 63 for longitudinal adjustment, and after adjustment, the normal removal movement of the identification member 658 is not affected, thereby further improving the practicality of the calibration component 65;

[0062] The bottom of the connecting plate 642 is hinged to two inclined transmission frames 657 through a bracket, and the bottom ends of the two transmission frames 657 are rotatably connected to the outer surface of the longitudinal shaft 653;

[0063] The transmission frame 657 is hinged to the bottom of the connecting plate 642 through the bracket, so that when the connecting plate 642 moves downward, it can drive the inclined transmission frame 657 to move in a fan shape, and then drive the longitudinal axis 653 to move horizontally. Indirectly, the L-shaped connecting rod 654 can drive the identification member 658 to move to one side, so as to facilitate the overlap of the drill bit of the punching machine body 63 and the punching mark position. With the start of the punching machine body 63, the punching process of the steel beam body 2 can be formed. On the contrary, through the upward movement of the connecting plate 642, the identification member 658 in the calibration component 65 can be reset.

[0064] See attached Figures 1 to 11 , a method for using a processing device for a heavy-duty assembled steel beam, comprising the following steps:

[0065] S1, transporting the steel beam body 2 with or without the marked punching positions to the processing area of ​​the processing table 1 through the electric transport component 3;

[0066] S2, the steel beam body 2 is adjusted transversely by the electric transmission component 3, the punching machine body 63 and the calibration end of the calibration component 65 are adjusted longitudinally by the driving component 64 in the processing mechanism 6, and the steel beam body 2 marked with the punching position is calibrated by the calibration component 65 in the processing mechanism 6, or the steel beam body 2 without the punching position is marked and calibrated;

[0067] S3, after the punching position is calibrated, the two sides of the calibrated steel beam body 2 are tightly fixed by the fixing mechanism 5 on the processing table 1, and finally the calibration component 65 is moved away by the driving component 64, and the punching machine body 63 is simultaneously fed downward to form the punching processing work of the steel beam body 2

[0068] Embodiment 2: Based on embodiment 1, the difference is that;

[0069] See attached Figure 8The identification member 658 includes a sleeve 6581 fixed to the bottom end of the L-shaped connecting rod 654, and a pressing rod 6582 is slidably connected inside the sleeve 6581, and an extrusion spring 6583 for pressing the pressing rod 6582 upward is fixedly connected inside the sleeve 6581, and the top and bottom ends of the pressing rod 6582 both extend to the outside of the sleeve 6581, and a marking head 6584 is detachably installed at the bottom end of the pressing rod 6582, and a pressing plate 6585 is fixedly connected to the top end of the pressing rod 6582;

[0070] By setting the marking head 6584, it is convenient to adjust the position of the steel beam body 2 through the electric transmission component 3, and adjust the drill position of the punching machine body 63 through the driving component 64. When the marking head 6584 matches the marked position of the steel beam body 2, the calibration work of the punching area can be formed;

[0071] The marking head 6584 includes a marking pen for marking, such as chalk. By pressing the pressing rod 6582 downward with the hand, the marking head 6584 can be driven to move downward. By the downward movement, the marking head 6584 comes into contact with the steel beam body 2 to form a punching position mark, which is convenient for improving the accuracy of subsequent punching processing, and meets the needs of punching calibration for the pre-marked steel beam body 2 and real-time marking calibration.

[0072] Embodiment 3: Based on embodiment 1, the difference is that;

[0073] See attached Figure 4 , Fig.10 and Fig.11 The fixing mechanism 5 includes two U-shaped plates 51 slidably connected to the top of the processing table 1, the inner sides of the two U-shaped plates 51 are fixedly connected with a tightening block 52, the bottoms of the two U-shaped plates 51 extend to the inside of the processing table 1, and two groups of spring members 54 are installed inside the processing table 1 through a fixing frame, one end of the two groups of spring members 54 is respectively fixedly connected to the inner sides of the two U-shaped plates 51, and a driving member for relatively driving the two U-shaped plates 51 is provided on the processing table 1;

[0074] By driving the two U-shaped plates 51 in relative directions, the two sets of abutting blocks 52 can be driven to move in relative directions, thereby forming a fastening work of the steel beam body 2, and the driving member includes but is not limited to an electric cylinder for horizontally reciprocatingly driving the U-shaped plates 51;

[0075] The driving member includes two driving plates 55 slidably connected to the top of the processing table 1. The bottoms of the two driving plates 55 extend to the inside of the processing table 1. The bottoms of the two driving plates 55 are respectively hinged with inclined tilting frames 56 with two U-shaped plates 51. One side of the bottom of the connecting plate 642 is fixedly connected with a touch frame 57 for pressing the driving plate 55 downward.

[0076] The downward movement of the two driving plates 55 can drive the two inclined tilting frames 56 to move in a fan shape, and then drive the two U-shaped plates 51 to move in relative directions. The relative movement of the two U-shaped plates 51 can tighten and fix the two sets of abutting blocks 52 on both sides of the steel beam body 2, thereby ensuring the stability of the steel beam processing of the steel beam body 2.

[0077] When the touch frame 57 is fixed with the connecting plate 642, when the connecting plate 642 moves downward, it can not only drive the punching machine body 63 and the calibration component 65 to perform the punching calibration work, but also can synchronously drive the two touch frames 57 to move downward. When the two touch frames 57 move downward until they contact the top of the driving plate 55, their continuous downward movement can squeeze the driving plate 55 downward, thereby making the two U-shaped plates 51 move in relative directions, forming a synchronous tightening work of the steel beam body 2, and having a good linkage function.

[0078] An L-shaped telescopic plate 53 is slidably inserted on the top of the two driving plates 55, and a locking member for locking the L-shaped telescopic plate 53 for height adjustment is provided on the two driving plates 55;

[0079] An L-shaped telescopic plate 53 is inserted and slidably inserted on the top of the driving plate 55, so that the length of the driving plate 55 can be changed by adjusting the telescopic adjustment of the L-shaped telescopic plate 53, and then the contact position between the touch frame 57 and the driving plate 55 can be changed to form a fixing work of the steel beam body 2 of different widths. The locking piece is set to lock the L-shaped telescopic plate 53 after the height adjustment, so as to improve the stability of its subsequent driving;

[0080] The specific operation method is as follows: when the L-shaped telescopic plate 53 is adjusted upward, its touch frame 57 moves downward following the connecting plate 642, the driving plate 55 can be moved downward in advance through the L-shaped telescopic plate 53 to fix the steel beam body 2 in advance, and vice versa.

[0081] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
