Description

Technical Field

[0001] The present invention relates to the technical field of profile punching equipment, and particularly to a profile punching device for steel structure assembly with clamping and fixing. Background Art

[0002] Profiles refer to steel or other metal materials with a certain cross-sectional shape and size made through processes such as rolling, extrusion, or drawing. Common profiles include I-beams, channel steels, angle steels, round steels, square steels, and H-beams, etc. They are widely used in fields such as construction, machinery manufacturing, and bridge construction, and serve as structural components or parts. If profiles need to be connected and installed with other components or meet specific functional requirements such as ventilation and decoration, punching processing is usually required. For example, in building structures, I-beams or channel steels may need to be punched to install connecting bolts; in machinery manufacturing, profiles may need to be punched to install components or achieve specific fluid flow functions.

[0003] When the existing profile punching device is in use, to ensure the punching quality, the hole sizes of the upper and lower dies need to be the same. For the situation where different-sized holes need to be punched on different profiles, workers only need to replace the upper and lower dies of the device before punching the profiles. However, for the situation where different-sized holes need to be punched on the same profile, since the lower die is located inside the lower part of the profile during the processing and is not easy to replace, workers can only replace the upper and lower dies uniformly after punching each size of hole and then punch the profile again, which results in a relatively low overall punching efficiency of the device for profiles. Moreover, the existing lower die can usually only be adapted to one size of profile, so when punching profiles of different sizes, the lower die needs to be frequently replaced, further reducing the overall punching efficiency of the device.

[0004] Based on the above situation, the present invention proposes a profile punching device for steel structure assembly with clamping and fixing, which has high punching efficiency and good effect. Summary of the Invention

[0005] In order to overcome the drawback that the existing profile punching device needs to frequently replace the lower die when punching different-sized holes on the same profile and when punching profiles of different sizes, resulting in a relatively low overall punching efficiency of the device for profiles, the present invention provides a profile punching device for steel structure assembly with clamping and fixing, which has high punching efficiency and good effect.

Detailed implementation manners

[0032] The following details the preferred technical solutions of the present invention with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] A profile punching device for steel structure assembly with clamping and fixing, as Figures 1-5As shown in the figure, it includes a machine frame 1, a punching machine 11, a placing table 12, a clamping assembly 13, a support plate 14, a motor 15, a lead screw 16, a top block 17, a moving frame 18, a threaded rod 19, a clamping block 110 and a spring piece 111. The punching machine 11 is fixedly connected to the upper part of the front side of the machine frame 1, the placing table 12 is fixedly connected to the lower part of the front side of the machine frame 1, the clamping assembly 13 is installed in the middle of the placing table 12, the support plate 14 is rotatably connected to the right side of the placing table 12, the motor 15 is fixedly connected to the right side of the support plate 14, the output end of the motor 15 is fixedly connected to the lead screw 16 through a coupling, the moving frame 18 is slidably connected to the left side of the support plate 14, the moving frame 18 is threadedly connected to the lead screw 16, the top block 17 is slidably connected to the upper part of the moving frame 18, and spring pieces 111 symmetrically distributed front and back are fixedly connected to both the left and right sides between the top block 17 and the moving frame 18. The clamping blocks 110 are slidably connected to both the front and back sides inside the moving frame 18, the clamping blocks 110 are in contact and cooperation with the top block 17, and the threaded rods 19 are rotatably connected to both the front and back sides of the moving frame 18, and the threaded rods 19 are threadedly connected to the adjacent clamping blocks 110.

[0035] As Figures 3-5 shown, the upper left part of the top block 17 is provided with an inclined surface and circular holes with different sizes axially distributed in the middle.

[0036] As Figure 4 shown, the clamping block 110 is in a stepped shape.

[0037] When a worker needs to punch a profile, taking an I-beam as an example, the worker can first rotate components such as the support plate 14 to fit the plane at the top of the placement table 12. Then, place the right end of the I-beam on the left side of the placement table 12 and move the I-beam as a whole to the right by a certain distance. During the rightward movement of the I-beam, it will contact and squeeze the top block 17, causing the top block 17 to move downward. The elastic piece 111 will be compressed immediately, and the top block 17 will closely adhere to the bottom of the web of the I-beam under the action of the elastic piece 111. At this time, the worker can rotate the threaded rod 19 forward, causing the front and rear clamping blocks 110 to move towards each other until the clamping blocks 110 contact the bottom of the top block 17. Since the clamping blocks 110 are stepped, the clamping blocks 110 can adapt to the top blocks 17 at different heights and support them, and the top block 17 can also adapt to I-beams of different sizes with the help of components such as the clamping blocks 110 and support the web of the I-beam, thus preventing the I-beam from deforming during the punching process and affecting the punching effect. Next, the worker can first move the I-beam to a suitable position to the right and limit the I-beam through the clamping assembly 13 to prevent the I-beam from shifting during the punching process. Then, the punching machine 11 can be started to punch the I-beam. And after each punching, the worker needs to move the I-beam to the right by a suitable distance and then continue the punching process. During this period, when the worker needs to punch holes of different sizes on the same profile, since there are circular holes of different sizes axially distributed on the top block 17, the worker can first replace the punch assembly on the punching machine 11, and then drive the lead screw 16 to rotate through the motor 15. The rotation of the lead screw 16 will drive components such as the moving frame 18 and the top block 17 to move left or right to a suitable position. At this time, the circular hole on the top block 17 that adapts to the new punch assembly will move directly below the punching machine 11, so as to quickly adapt to the required punching size by adjusting the position of the top block 17 and avoid the need for frequent replacement of the lower die. After the punching process is completed, the worker can first remove the I-beam from the placement table 12. At this time, the top block 17 will move upward and reset under the action of the elastic piece 111. Then, the components such as the moving frame 18 and the clamping blocks 110 can also be moved in the reverse direction and reset through components such as the motor 15 and the threaded rod 19.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, as Figures 6-8As shown, a lubrication mechanism is also included, which is arranged on the placement table 12. The lubrication mechanism includes a limit frame 2, a mounting frame 21, a screw 22, a limit ring 23, a liquid tank 24, a sponge ring 25 and a liquid guide tube 26. The two mounting frames 21 are respectively fixed to the front and rear sides of the lower part of the placement table 12, and the limit frame 2 is slidably connected between the front and rear mounting frames 21. The top of the mounting frame 21 is rotatably connected with a screw 22, and the screw 22 is threadedly connected to the limit frame 2. The middle part of the limit frame 2 is fixedly connected with the limit ring 23, and the middle part of the limit ring 23 is fixedly connected with a sponge ring 25. The right side of the limit frame 2 is fixedly connected with a liquid tank 24, and a liquid guide tube 26 is fixedly connected and connected between the liquid tank 24 and the sponge ring 25.

[0040] Before starting the punch 11, the worker can also rotate the screw 22 in the forward direction and drive the limit frame 2, the limit ring 23 and the sponge ring 25 and other components to move downward until the limit ring 23 contacts the top of the web of the I-beam. At this time, the limit ring 23 will cooperate with the top block 17 and support and fix the punching part of the I-beam, thereby avoiding deformation near the hole of the I-beam due to punching. Since lubricating oil is stored in the liquid tank 24 and the liquid level of the lubricating oil is higher than the sponge ring 25, the lubricating oil in the liquid tank 24 will enter the sponge ring 25 through the liquid guide tube 26 until the sponge ring 25 is saturated with adsorption. At this time, the lubricating oil in the sponge ring 25 will not actively flow out due to its own surface tension and the adsorption force of the sponge ring 25. When the movable punch assembly moves downward and punches the web of the I-beam, the punch assembly on the puncher 11 will contact and squeeze the sponge ring 25, thereby deforming the sponge ring 25. Part of the lubricating oil adsorbed inside the sponge ring 25 is also squeezed out and attached to the surface of the punch assembly, so that the friction between the puncher 11 and the I-beam can be reduced by the lubricating oil and the wear of the puncher 11 can be avoided. When the puncher 11 drives the punch assembly to move upward and reset, the sponge ring 25 also returns to its original state under the action of its own elasticity and draws part of the lubricating oil from the liquid tank 24 through the liquid guide tube 26 for replenishment. After the punching process is completed, the worker can reversely rotate the screw 22 and drive the limit frame 2, the limit ring 23 and the sponge ring 25 and other components to move upward and reset.

[0041] like Figure 1 and Figure 9 As shown, it also includes a supporting mechanism, which is arranged on the placement table 12. The supporting mechanism includes a rotating frame 3, a supporting frame 31 and a guide wheel 32. The two supporting frames 31 are respectively fixed to the front and rear parts of the left side of the placement table 12. The rotating frame 3 is rotatably connected between the front and rear supporting frames 31, and the guide wheel 32 is rotatably connected to the top of the rotating frame 3.

[0042] Before placing the I-beam, the worker can also rotate the rotating frame 3 and the guide wheel 32 to the left and unfold them. Among them, the rotating frame 3 can only rotate to the horizontal state at most under the structural limitation of the support frame 31 and cannot continue to rotate downward. After that, when the worker places the I-beam on the placing table 12, the rotating frame 3 and the guide wheel 32 can support the suspended part on the left side of the I-beam, thus preventing the I-beam from deforming due to partial suspension and affecting the punching quality. After the punching process is completed, the worker can rotate the rotating frame 3 and the guide wheel 32 to the right to reset and return to the folded state.

[0043] As Figure 1 and Figure 10 shown, there is also a grinding mechanism. The grinding mechanism is arranged on the machine frame 1. The grinding mechanism includes a connecting frame 4, a fixing frame 41 and a grinding machine 42. The fixing frame 41 is fixedly connected to the left part of the front side of the machine frame 1. The front part of the fixing frame 41 is slidably connected with the connecting frame 4. A bolt is threadedly connected to the front side of the fixing frame 41, and the bolt is in contact and cooperation with the connecting frame 4. The bottom of the connecting frame 4 is fixedly connected with the grinding machine 42.

[0044] As Figure 10 shown, the grinding machine 42 is inclined.

[0045] Before starting the punching machine 11, the worker can adjust the connecting frame 4 and the grinding machine 42 to a suitable height according to the size of the I-beam. When the worker moves the I-beam to the right and punches the I-beam with the punching machine 11, the grinding machine 42 can also be started. The grinding machine 42 can slightly grind the punched part of the I-beam, thus preventing impurities such as oxide scale, rust, dirt and burrs from existing on the web surface of the I-beam and affecting the punching accuracy and quality. Since the grinding machine 42 is inclined, the debris and impurities generated by grinding will be piled up behind the web of the I-beam under the guidance of the grinding machine 42. After the punching process is completed, turn off the grinding machine 42 and clean the debris and impurities.

[0046] As Figure 11 and Figure 12 shown, there is also a cleaning mechanism. The cleaning mechanism is arranged on the limiting frame 2. The cleaning mechanism includes a connecting pipe 5, a suction plate 51 and a material pump 52. The suction plate 51 is fixedly connected to the left side of the limiting frame 2. The upper part of the left side of the limiting frame 2 is fixedly connected with the connecting pipe 5. One end of the connecting pipe 5 is fixedly connected and communicated with the suction plate 51. The other end of the connecting pipe 5 is fixedly connected and communicated with an external collection component. The material pump 52 is fixedly connected to the middle part of the machine frame 1, and the material pump 52 is fixedly connected and communicated with the connecting pipe 5.

[0047] When punching the I-beam, the worker can also start the material pump 52. The material pump 52 will absorb the impurities remaining on the surface of the I-beam through the connecting pipe 5 and the suction plate 51 and transport them to the external collection component, so as to clean the impurities on the surface of the I-beam, thereby avoiding other impurities generated by grinding remaining on the surface of the I-beam and affecting the subsequent punching process. After the punching process is completed, turn off the material pump 52 and process the impurities in the external collection component.

[0048] It should be understood that the above description is only for illustrative purposes and does not mean to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
