Description

Technical Field

[0001] This patent application belongs to the technical field of strip production equipment in the metallurgical industry. More specifically, it relates to an anti-collision guiding device applied to the strip annealing equipment of a laser welding machine. Background Art

[0002] In the production line of continuous strip processing, whether it is an acid pickling line or a galvanizing line, annealing equipment needs to be applied during the strip welding process, and the laser welding machine annealing equipment needs to be protected during the operation of the C-frame trolley of the welding machine.

[0003] During the operation of the C-frame of the laser welding machine, due to reasons such as the strip's own shape and material strength, or during the operation of the C-frame of the laser welding machine, it is easy for the laser welding machine annealing equipment to rub against the strip, resulting in damage to the heating coil of the annealing equipment, and ultimately leading to equipment short-circuit and shutdown. Therefore, it is necessary to install a protection device to protect the exposed position of the annealing device. Before the annealing device contacts the strip, there should be necessary protection and sensor detection to make it stop in time and avoid the advancing strip from damaging the equipment.

[0004] Based on the above situation, it is necessary to set up an anti-collision device on the outer side of the C-frame walking of the annealing device of the laser welding machine. Its function is to ensure that the annealing device does not directly contact the annealer when the C-frame trolley is walking during welding, and the flat strip can travel stably in the channel after welding, which also provides a prerequisite for the weld quality. However, before entering the welding machine, the strip annealing anti-collision device is easily damaged by the strip with poor shape and warping, which affects the fast-paced production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an anti-collision guiding device applied to the strip annealing equipment of a laser welding machine, to avoid the annealing device being damaged by the strip with poor shape and warping, and to solve the problems existing in the background art.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] The guiding stop block includes an inclined plate inclined to the horizontal line, openings provided on both sides of the upper part of the inclined plate, and a top plate connected to the top end of the inclined plate. The inclined plate faces the running direction of the C-shaped frame trolley of the laser welding machine, and its middle part is for fixing the fixing bracket of the photoelectric switch. The openings are for fixing the protruding ends of the photoelectric switch, and the top plate is connected to the top ends of the two fixing brackets.

[0009] Furthermore, the fixing bracket of the photoelectric switch includes a substrate, fixing clamping grooves provided at both ends of the substrate and matching with the photoelectric switch, and a plurality of connecting plates vertically provided in the middle of the substrate. The connecting plates are fixed on the inclined plate close to the opening and are located below the opening.

[0010] Furthermore, the photoelectric switch is circular, the substrate is rectangular, the fixing clamping grooves are circular or semi-circular, and the number of connecting plates is 2 to 5.

[0011] Furthermore, one end of the supporting base is a flat surface and the other end is an inclined surface. The flat surface is connected to the middle part of the fixing base, and the inclined surface is connected to the inclined plate of the guiding stop block.

[0012] Furthermore, the included angle between the guiding stop block and the horizontal plane of the running direction of the C-shaped frame trolley of the laser welding machine is 45° to 60°.

[0013] Furthermore, a plurality of anchor holes are provided at the end of the fixing base, and anchor bolts are provided for the anchor holes. The fixing base is fixed to the front end of the corresponding annealing equipment through the anchor bolts.

[0016] The structure of this device is simple, the manufacturing cost is low, and the parts are easy to replace. It can avoid the situation that the annealing equipment of the laser welding machine scratches the strip steel due to reasons such as the strip steel's own plate shape and material strength during the operation of the C-shaped frame of the laser welding machine, resulting in the annealing equipment being scratched to expose the heating coil, and then causing the equipment to short-circuit and shut down.

[0024] The following further describes the present utility model in detail with reference to the embodiments.

[0025] An anti-collision guiding device applied to the strip annealing equipment of a laser welding machine, as Figure 1 , Figure 2 , is horizontally arranged at the running passage of the C-shaped frame of the laser welding machine, and includes an I-shaped fixing base 5, a supporting base 6 horizontally and vertically arranged in the middle of the fixing base 5, two fixing brackets 4 inclinedly arranged in the middle of the fixing base 5, a guiding stop block 1 with its bottom connected to the other end of the supporting base 6, a photoelectric switch fixing bracket 3 arranged in the middle of the guiding stop block 1, and a photoelectric switch 2 fixed on the photoelectric switch fixing bracket 3 through a connecting bolt. The protruding end of the photoelectric switch 2 is fixedly welded on the guiding stop block 1. The function of the photoelectric switch 2 is to provide deceleration signals and stop signals. After detecting a severely deformed strip, the equipment is decelerated and stopped in advance to prevent further severe collisions.

[0026] The extension lines of the two fixing brackets 4 are in a crossed shape, but the two fixing brackets 4 do not directly cross. The top of the guiding stop block 1 is connected to the tops of the two fixing brackets 4.

[0027] As Figure 5 , the guiding stop block 1 includes an inclined plate 11 inclined with respect to the horizontal line, openings 12 arranged on both sides of the upper part of the inclined plate 11, and a top plate 13 connected to the top end of the inclined plate 11. The inclined plate 11 faces the running direction of the trolley of the C-shaped frame of the laser welding machine, and its middle part is for fixing the photoelectric switch fixing bracket 3. The opening 12 is for fixing the protruding end of the photoelectric switch 2, and the top plate 13 is connected to the tops of the two fixing brackets 4.

[0028] As Figure 1 , Figure 2 , Figure 6, the photoelectric switch fixing bracket 3 includes a base plate 31, fixing card slots 32 provided at both ends of the base plate 31 and matching the photoelectric switch 2, and a plurality of connecting plates 33 vertically provided in the middle of the base plate 31. The connecting plates 33 are fixed on the inclined plate 11 close to the opening 12 and are located below the opening 12, that is, the connecting plates 33 are fixed below the opening 12. The photoelectric switch 2 is fixed on the inclined plate 11 through the photoelectric switch fixing bracket 3 and passes through the opening 12. Finally, the protruding end of the photoelectric switch 2 is fixedly welded to the opening 12 of the guiding stop block 1.

[0029] As Figures 1 to 4 , the photoelectric switch 2 is circular, the base plate 31 is rectangular, the fixing card slots 32 are circular or semi-circular, and the number of connecting plates 33 is 2 to 5.

[0030] In Figure 1 , one end of the support base 6 is a flat surface and the other end is an inclined surface. The flat surface is connected to the middle of the fixed base 5, and the inclined surface is connected to the inclined plate 11 of the guiding stop block 1.

[0031] The angles between the guiding stop block 1, the photoelectric switch fixing bracket 3 and the horizontal plane of the running direction of the laser welding machine C-type frame trolley are 30° to 60°, preferably 45°.

[0032] In Figure 1 , a plurality of anchor holes are provided at the end of the fixed base 5. The anchor holes are equipped with anchor bolts, and the fixed base 5 is fixed to the front end of the corresponding annealing equipment through the anchor bolts. As Figure 2 , the length of the protruding end of the photoelectric switch 2 is wider than the thickness of the inclined plate 11, and the bottom of the inclined plate 11 is an inclined cutting surface.

[0033] The usage process of this device is as follows:

[0034] First, as Figure 1 , Figure 2 , arrange this anti-collision guiding device horizontally on the laser welding machine C-type frame annealing equipment.

[0035] When the laser welding machine strip annealing equipment is running and encounters serious deformation of the strip, first, the photoelectric switch 2 in the anti-collision guiding device provides deceleration signals and stop signals. After detecting the deformed strip, the equipment is decelerated and stopped in advance to prevent serious mis-collision.

[0036] The angle between the guiding stop block 1 and the horizontal plane of the strip is 45° to 60°, preferably 45°. The anti-collision guiding device uses the guiding stop block 1 to guide the strip to smoothly enter the annealing equipment area, reducing the impact on the annealing equipment due to poor strip shape, warping, etc., and achieving the purpose of protecting the laser welding machine annealing equipment.
