[0002] In the construction of civil engineering computer rooms, steel bars, as the core load-bearing structural material, directly affect the structural stability and safety of the building due to their processing precision. Laser cutting technology, with its advantages of high cutting precision, smooth cuts, and small heat-affected zone, has been widely used in steel bar processing, and corresponding laser cutting equipment for steel bars has become one of the key pieces of equipment in the construction of civil engineering computer rooms.

[0003] However, existing laser cutting devices for steel bars used in civil engineering computer room construction still have many technical defects in practical applications. When fixing steel bars at multiple points, existing devices mostly rely on manual operation, which makes the operation cumbersome and inconvenient. The manual locking method requires the operator to manually tighten multiple clamps after the steel bars are placed to complete the fixation, and then manually unlock the multiple clamps after the cutting is completed. This not only consumes manpower but also greatly extends the operation interval time, making it unsuitable for continuous processing of batches of steel bars. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the weight of the steel bar itself is used as the locking driving force, which can realize the simultaneous locking of multiple points of the steel bar bar. It is highly convenient. After the steel bar is placed in the feeding component, the pressure is transmitted to the lifting plate through the placement frame and the pressure rod, which in turn drives the locking transmission component to drive the fixing component to clamp and fix the steel bar from both sides. This can effectively prevent the steel bar from shaking during laser cutting. At the same time, the toggle block on the fixing component synchronously drives the stop component to lock the feeding component, preventing the feeding component from accidentally moving the steel bar and causing cutting misalignment.

[0016] 2. In the initial state, the lifting push rod lifts the lifting plate to unlock the locking mechanism, facilitating the feeding and conveying of the reinforcing bar. After the reinforcing bar is placed, the lifting push rod retracts, the device automatically locks and performs laser cutting. After cutting, the lifting push rod lifts the lifting plate again, which quickly releases the locking state of multiple sets of fixing components and stop components, facilitating the continued conveying of the reinforcing bar to the next cutting point. This realizes continuous operation of multi-point cutting of reinforcing bars. Compared with the traditional device, which requires manual unlocking, adjustment of the reinforcing bar position and relocking after each cut, the operation interval time is greatly shortened.

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 This application provides a laser cutting device for steel bars in civil engineering computer room construction, including a base 100 and steel bars 400, and a laser cutting unit 200 for cutting steel bars 400 is installed on the top surface of the base 100. It should be noted that the laser cutting unit 200 includes a gantry frame 201, a first linear conveyor motor 202, a second linear conveyor motor 203, a mounting base 204, a third linear motor, and a laser cutting tool assembly 205. The gantry frame 201 is slidably mounted on the top surface of the base 100, and the third linear motor is mounted on the base 100 to drive the gantry frame 201 to move along the Y-axis. The laser cutting tool assembly 205 is mounted on the gantry frame 201 via the mounting base 204. The gantry frame 201 is used to elevate the laser cutting tool assembly 205 so that, in its initial state, it is higher than the position of the reinforcing bar 400. The first linear conveyor motor 202 and the second linear motor 203... Linear conveyor motor 203 is installed between the gantry 201 and the laser cutting tool assembly 205 to adjust the position of the laser cutting tool assembly 205 in the X and Z axis directions. In addition, linear conveyor motors 202, 203, and 3, as well as the laser cutting tool assembly 205, are all existing mature technologies. Linear conveyor motors 202, 203, and 3 are only used to adjust the position of the laser cutting tool assembly 205 in the X, Y, and Z axis directions. The laser cutting tool assembly 205 is only used to cut steel bar 400, so this solution directly uses it and will not be described in detail. An automatic locking unit 300 is also installed on the base 100, wherein the automatic locking unit 300 includes There are several placement racks 301 arranged in parallel. It should be noted that at least two stress points are required to support the steel bar 400. Therefore, this solution preferably uses two placement racks 301. Thus, the figure only shows two placement racks 301. Each placement rack 301 is equipped with a set of feeding components 305 for supporting and conveying the steel bar 400, and a pressure bar 302 is fixedly installed on the bottom surface of each placement rack 301. The lifting plate 309 is located below multiple pressure rods 302. A sliding shaft 312 is fixedly connected to the top surface of the lifting plate 309. All pressure rods 302 are slidably connected to the sliding shaft 312, which can play a guiding role, so that the pressure rods 302 can only move along the axial direction of the sliding shaft 312, avoiding the problem of misalignment between the laser cutting tool assembly 205 and the steel bar 400. The locking transmission component 303 is disposed on the bottom surface of the lifting plate 309, and the locking transmission component 303 is provided with a fixing component 304. The lifting plate 309 applies the pressure from the steel bar 400 on the feeding component 305 to the locking transmission component 303, and the locking transmission component 303 drives the fixing component 304 to fix the position of the steel bar 400. The stop component 306 is provided in multiple sets, and is provided in pairs on each placement rack 301. The fixing component 304 is provided with a lever 317, which is used to drive the stop component 306 to restrict the movement of the corresponding feed component 305 on each placement rack 301. The top block 314 is located between the base 100 and the lifting plate 309. A lifting push rod 313 is fixedly installed on the top surface of the base 100. The output end of the lifting push rod 313 is fixedly connected to the bottom surface of the top block 314. Since the lifting plate 309 has a large length, multiple sets of top blocks 314 and the lifting push rods 313 below them are provided to drive its movement, so that the bottom surface of the lifting plate 309 is subjected to a uniform thrust.

[0021] Specifically, in the initial state, the lifting push rod 313 drives the top block 314 to lift the lifting plate 309. Then, part of the rebar 400 is placed above the two feeding components 305. Subsequently, the lifting push rod 313 drives the top block 314 to descend to a position where it is not in contact with the lifting plate 309. Since the rebar 400 has its own weight, the feeding components 305 transmit the pressure of the rebar 400 to the placement frame 301. The placement frame 301 transmits the pressure to the lifting plate 309 through the pressure rod 302. The lifting plate 309 then drives the fixing component 304 to clamp the rebar 400 in place. This prevents the rebar 400 from wobbling on the feeding component 305 during the laser cutting process by the laser cutting tool assembly 205, ensuring... To ensure the stability of the reinforcing bar 400, the toggle block 317 on the fixing component 304 drives the stop component 306 to fix the feed component 305, further ensuring the stability of the reinforcing bar 400. This prevents the feed component 305 from moving the reinforcing bar 400 on it, causing misalignment between the laser cutting part and the laser cutting tool assembly 205. After the reinforcing bar 400 is cut at the designated position, the lifting push rod 313 is activated again to drive the top block 314 to lift the lifting plate 309. As a result, the stop components 306 of the fixing component 304 become ineffective, and the reinforcing bar 400 can be fed again to perform laser cutting on the next point. This is more convenient and allows for the simultaneous fixing and unfixing of multiple points of the reinforcing bar 400.

[0022] Furthermore, the locking transmission assembly 303 includes Branch plates 3031 are provided in multiple ways and are slidably mounted on lifting plates 309. Two upper hinge seats 3032 are fixedly connected to the bottom surface of each lifting plate 309. A transmission connecting rod 3033 is hinged to each upper hinge seat 3032. A lower hinge seat 3034 is hinged to the end of the transmission connecting rod 3033 away from the upper hinge seat 3032. A sliding seat 3035 is fixedly connected to the bottom surface of the lower hinge seat 3034. The first guide shaft 3037 is provided in several parts and is slidably disposed on the base 100, and a sliding seat 3035 is slidably connected to two corresponding sliding seats 3035; There are several extension frames 3036. The bottom end of each extension frame 3036 is fixedly connected to a corresponding sliding seat 3035 and extends upward through the branch plate 3031 and the base 100. They are located on both sides of the steel bar 400 in pairs. Each fixing component 304 is installed on an extension frame 3036.

[0023] Specifically, when the lifting plate 309 is subjected to pressure, it can drive all the branch plates 3031 on it to move downwards. Then, under the action of the transmission link 3033 between the upper hinge seat 3032 and the lower hinge seat 3034, it pushes the sliding seats 3035 located on the same two first guide shafts 3037 to move towards each other. The sliding seats 3035 located on the same two first guide shafts 3037 cooperate to drive the fixing components 304 on the extension frame 3036 to clamp from both sides of the steel bar 400.

[0024] Furthermore, each set of fixing components 304 includes The fixed base 3041 is fixedly connected to a corresponding extension bracket 3036, and an adjustment component is installed on each fixed base 3041; The locking block 3046 is set on the adjusting component. A rubber pad 3047 is fixedly set on the side wall of the locking block 3046 to increase the friction between the reinforcing bars 400, so as to improve the effect of fixing the reinforcing bars 400.

[0025] Specifically, the two extension brackets 3036 used in cooperation move towards each other, causing the fixed base 3041 to move towards the steel bar 400, which in turn causes the locking block 3046 on it to move. The locking block 3046 then adheres to the outer wall of the steel bar 400 through the rubber pads 3047. The two rubber pads 3047 form a holding force to fix the non-laser-cut area of ​​the steel bar 400.

[0026] Furthermore, each group of feed components 305 includes The fixed shaft 3051 is fixedly connected to the placement frame 301; Two connecting sleeves 3053 are provided and both are sleeved on the fixed shaft 3051. One end of each connecting sleeve 3053 is fixedly connected to a connecting sleeve 3053, and the other end is fixedly connected to a feeding wheel 3054. The feeding wheel 3054 is used to carry and transport the steel bar 400. By placing the steel bar 400 between the two feeding wheels 3054, the steel bar 400 can be pushed forward, thereby performing laser cutting on different points of the steel bar 400.

[0027] Furthermore, the adjustment components include The adjusting screw 3042 is rotatably connected to the side wall of the locking block 3046 facing away from the rubber pad 3047, and a threaded block is fixedly provided on the top of the fixing base 3041. The adjusting screw 3042 is threadedly connected inside the threaded block. A handwheel is fixedly connected to the end of the adjusting screw 3042 away from the locking block 3046 to facilitate the rotation of the adjusting screw 3042. Hollow tube 3043 is fixedly connected to fixed base 3041. A slide rod 3045 is slidably connected inside hollow tube 3043. The end of slide rod 3045 away from hollow tube 3043 is fixedly connected to locking block 3046.

[0028] Furthermore, each group of stop components 306 includes A U-shaped seat is provided on the top of the placement rack 301, and a rotating seat 3064 is fixedly connected to the top of the U-shaped seat. A gear 3065 is rotatably connected to the rotating seat 3064, and a rack 3062 is meshed with the top and bottom of the gear 3065 respectively. Two U-shaped frames 3066 are provided, and one end of each U-shaped frame 3066 is connected to a corresponding rack 3062 via a connecting bracket 3063. A locking piece 3068 is fixedly connected to the other end of the U-shaped frame 3066. It should be noted that the contact surface of the locking piece 3068 and the resistance plate 3052 is made of rubber with a high static friction coefficient, which can restrict the movement of the resistance plate 3052 by friction. The two locking pieces 3068 are located on both sides of a resistance plate 3052. The second return spring 3067 is sleeved on the outside of each U-shaped frame 3066, with one end fixedly connected to the locking piece 3068 and the other end fixedly connected to the U-shaped seat. The heightening block 3061 is fixedly installed on the top of the rack 3062 located above the gear 3065, and a lever 317 for pushing the heightening block 3061 to move is fixedly connected to the hollow tube 3043. The height of the heightening block 3061 is high, so even if the placement frame 301 is moved downward by the pressure of the steel bar 400, its height is still higher than the height of the lever 317.

[0029] Specifically, during the clamping and fixing of the steel bar 400 by the two-component fixing components 304, the pusher block 317 can push the lifting block 3061 to move. The lifting block 3061 drives the rack 3062 connected to it to move. Under the action of the gear 3065, the lower rack 3062 and the upper rack 3062 move in opposite directions. Each rack 3062 drives the locking plate 3068 to clamp the resistance plate 3052 through the U-shaped frame 3066 connected to it, and uses its friction to lock the resistance plate 3052, which can prevent the rotation of the resistance plate 3052, that is, limit the rotation of the feeding wheel 3054, and further ensure the stability of the steel bar 400 placed on the feeding wheel 3054.

[0030] Furthermore, the automatic locking unit 300 also includes The second guide shaft 308 is provided in multiple ways and is fixedly connected to the base 100. The lifting plate 309 is fixedly connected to multiple fixing blocks 307, and each fixing block 307 is slidably arranged on a corresponding second guide shaft 308. There are multiple No. 3 return springs 310, and each No. 3 return spring 310 is sleeved on the outside of a corresponding No. 2 guide shaft 308. Each No. 2 guide shaft 308 is fixedly provided with a No. 2 stop block 311. The No. 3 return spring 310 is located between the No. 2 stop block 311 and the fixed block 307, and plays the role of reset.

[0031] Specifically, when the lifting plate 309 slides downward under pressure, the fixing block 307 slides downward on the corresponding second guide shaft 308, while the third return spring 310 is compressed. When the lifting plate 309 loses the pressure of the steel bar 400, it can push the fixing block 307 to reset the lifting plate 309 under the action of the third return spring 310.

[0032] Furthermore, a mounting platform 101 is fixedly installed on the base 100, and a sound-absorbing pad is fixedly connected to the top surface of the mounting platform 101. This can prevent the placement frame 301 from hitting the mounting platform 101 instantly after being subjected to the pressure of the steel bar 400, thus avoiding the noise problem. Several insertion holes 104 are equally spaced on both the sound-absorbing pad and the mounting platform 101. Each placement rack 301 is equipped with a positioning ring 315, and the inner side of the positioning ring 315 is equipped with a plug rod 316 that is compatible with the insertion hole 104.

[0033] Specifically, by inserting the insertion rod 316 through the insertion positioning ring 315 and one of the insertion holes 104, the position of the placement rack 301 can be defined. When the rebar 400 needs to be cut, multiple placement racks 301 can be adjusted to the side of the laser cutting tool assembly 205. When slotting is only required at a specified position on the rebar 400, multiple placement racks 301 can be evenly distributed on both sides of the laser cutting tool assembly 205, so that the laser cutting tool assembly 205 is located in the middle. After this adjustment, the limitation of the stop component 306 on the resistance plate 3052 and the limitation of the fixing component 304 on the rebar 400 will not be affected.

[0034] Furthermore, the locking transmission assembly 303 also includes Multiple guide shafts 3037 are provided and slidably mounted on the base 100. A sliding seat 3035 slides on two corresponding guide shafts 3037, serving as a guide and allowing the sliding seat 3035 to move along the axial direction of the guide shaft 3037. Multiple reset springs 3039 are provided and are all sleeved on the first guide shaft 3037. Each first guide shaft 3037 is fixedly connected to a first stop block 3038. One end of each reset spring 3039 is fixedly connected to the sliding seat 3035, and the other end is fixedly connected to the first stop block 3038. The function of the reset spring 3039 is to drive the sliding seat 3035 to reset at the same time as the lifting plate 309 resets.

[0035] Specifically, before clamping, the adjusting screw 3042 can be rotated by rotating the handwheel according to the radius of the steel bar 400, and then the slide bar 3045 can slide inside the hollow tube 3043 to adjust the distance between the locking block 3046 and the fixing seat 3041, that is, to adjust the clamping force on the steel bar 400.

[0036] Furthermore, the mounting platform 101 is provided with a guide groove 102 for the pressure rod 302 to move, so that the pressure rod 302 can move inside the guide groove 102 during the adjustment of the position of the placement frame 301. The mounting platform 101 is also provided with a movable groove 103 for the extension frame 3036 to move, and the width of the movable groove 103 is greater than that of the extension frame 3036, so that the extension frame 3036 can move along the x-axis and Y-axis directions inside the movable groove 103.

[0037] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
