Description

Technical Field

[0001] This utility model relates to the field of channel steel processing technology, and in particular to a channel steel processing device. Background Technology

[0002] Forklift mast channel steel is divided into inner mast channel steel and outer mast channel steel. The cross-sectional shape of the channel steel is U-shaped. There are surfaces that need to be machined on the two mutually perpendicular surfaces of the U-shape. After machining, a roller shaft also needs to be welded onto the channel steel.

[0003] A search revealed Chinese Patent Publication No. CN210908956U, which discloses an automated production line for processing channel steel for forklift masts. The line includes a first machining center for machining screw holes in vertically oriented channel steel, a first positioning mold for fixing the vertically oriented channel steel, a second machining center for machining shaft holes in transversely oriented channel steel, a second positioning mold for fixing the transversely oriented channel steel, a channel steel flipping center for converting the channel steel between vertical and transverse states, a guide roller conveyor for conveying the channel steel to the first positioning mold, a roller shaft welding station for welding roller shafts to the channel steel, and a clamping roller conveyor for conveying the channel steel processed by the second machining center to the roller shaft welding station.

[0004] This patent improves the efficiency of channel steel processing and welding by rationally arranging the first machining center, the channel steel turning center, the second machining center, and the roller shaft welding station to complete four processes in sequence: channel steel bolt hole processing, channel steel turning, channel steel shaft hole processing, and roller shaft welding. However, it requires manual placement of the channel steel vertically on the guide roller conveyor. The channel steel itself is heavy and inconvenient to handle. Furthermore, the repetitive manual labor makes it difficult to control the interval of channel steel feeding, which may result in the channel steel accumulating on the guide roller conveyor.

[0028] Example 1

[0029] A channel steel processing device, such as Figures 1 to 2 As shown, the system includes a safety light curtain 2 fixed to the ground 1. The safety light curtain 2 is a rectangular ring with a notch on one side. Two transfer carriages 4 are fixed to the notch of the safety light curtain 2 by two parallel positioning components 3. One of the transfer carriages 4 has channel steel stacked inside. A handling robot 5 is set on one side of each of the two positioning components 3. An exchange table 6 is set between the two handling robots 5. The top of the exchange table 6 is provided with a limiting groove 7 for limiting the channel steel. A first machining center 8 is set on one side of one transfer carriage 4, and a second machining center 15 is set on one side of the other transfer carriage 4. Each of the transport robots 5 has a clamping platform 10 on one side. The clamping platform 10 is a combination structure of a processing table, a cylinder and a clamping plate. This structure is existing technology and will not be described in detail here. A cutting robot 9 is set on one side of one clamping platform 10, and a welding robot 11 is set on the other side of the clamping platform 10. The first processing center 8 and the cutting robot 9 are located on the same side of the exchange table 6. A collection box 14 is set on the clamping platform 10 on the side of the cutting robot 9 near the cutting robot 9. A hopper 13 for storing roller shafts is set on the side of the welding robot 11. A transport robot 2 12 is set on the side of the hopper 13.

[0030] When processing channel steel, a worker pushes a storage container of channel steel to be processed to a positioning component 3 located on one side of the first machining center 8. The positioning component 3 fixes the transfer carriage 4. Another empty transfer carriage 4 is pushed to another positioning component 3. A transport robot 5, located on the same side of the exchange table 6 as the first machining center 8, transports the channel steel on the transfer carriage 4 to a clamping table 10 located on one side of the cutting robot 9 for clamping and fixing. The cutting robot 9 performs flame cutting on the clamping table 10, and the waste generated from the cutting falls into a collection box 14. The cut channel steel is then transported by the transport robot 5 to the first machining center 8 for screw hole processing. After processing, the transport robot 5, located on the same side of the exchange table 6 as the first machining center 8, completes the process. The channel steel is transported to the exchange table 6 and placed there. The limiting slot 7 limits the channel steel. During the process of transporting the channel steel to the exchange table 6, the channel steel rotates 90 degrees. Then, another transport robot 5 transports the channel steel on the exchange table 6 to the second machining center 15. The second machining center 15 performs shaft hole processing on the channel steel. After the shaft hole is processed, it is transported by transport robot 5 to the clamping table 10 on one side of the second machining center 15 for clamping and fixing. Then, transport robot 12 places the roller shaft on the hopper 13 onto the channel steel and welds the roller shaft onto the channel steel by welding robot 11. Then, transport robot 5 transports the processed channel steel to the transfer frame 4 on one side of the second machining center 15 for stacking and storage.

[0031] By setting up positioning component 3, transfer frame 4 and handling robot 5, workers only need to push a transfer frame 4 with stacked channel steel to positioning component 3 to automatically load and process materials without manual loading.

[0032] By setting up a handling robot 5, an exchange platform 6, and a limiting groove 7, the channel steel can be flipped when placed on the exchange platform 6, eliminating the need for a dedicated channel steel flipping structure and simplifying the device's structure.

[0033] Example 2

[0034] A channel steel processing device, this embodiment is based on embodiment 1, with the following improvements, such as... Figures 3 to 5 As shown, the transfer frame 4 includes a support frame 16 and a connecting rod 17. The connecting rod 17 is fixed to the bottom end of the support frame 16, and a caster wheel 18 is fixed to the bottom end of the connecting rod 17. The positioning component 3 includes a positioning block 19 and two positioning grooves 20. The positioning block 19 is fixed to the ground 1, and the two positioning grooves 20 are opened at both ends of the positioning block 19. An inclined surface inclined towards the center line of the positioning groove 20 is provided on both sides of one end of the positioning groove 20. A moving rod 22 is slidably fitted on the inner wall of the positioning block 19. A tension spring connected to one end of the moving rod 22 is connected to one side of the moving rod 22. A pressing block 23 is connected to one end of the pressing block 23. An inclined block 24 is provided at both ends of the pressing block 23, which is laterally slidably fitted with the positioning block 19. The inclined surface of the pressing block 23 is slidably fitted with the inclined surface of the inclined block 24. A return spring is connected to one side of the inclined block 24, and the other end of the return spring is connected to the positioning block 19.

[0035] When transferring the channel steel via the transfer frame 4, push the support frame 16 and move it via the casters 18 to move the support frame 16 to one side of the positioning component 3, so that the connecting rod 17 is opposite to the positioning groove 20. Then continue to push the support frame 16 to move the connecting rod 17 into the positioning groove 20. When the connecting rod 17 is blocked by the positioning plate 21 and cannot move, step on one end of the moving rod 22. The pressing block 23 moves away from the inclined block 24, the tension spring stretches and deforms, and the return spring pushes the inclined block 24 to move the positioning plate 21, causing the positioning plate 21 to retract into the positioning block 19. At this time, push the support frame 16 to move one of the connecting rods 17 past the positioning plate 21 to one end of the positioning groove 20. Then release the moving rod 22, the tension spring contracts and causes the pressing block 23 to return to its original position. The two ends of the pressing block 23 press the inclined block 24 to move, causing the positioning plate 21 to extend and limit the position of the connecting rod 17.

[0036] By setting the positioning component 3, the transfer frame 4 is limited and fixed after it moves to the designated position, which facilitates the handling robot 5 to handle the channel steel.

[0037] Working principle: When processing channel steel, the worker pushes a channel steel to be processed to the positioning component 3 located on one side of the first machining center 8, with the connecting rod 17 facing the positioning groove 20. Then, the worker continues to push the support frame 16 to move the connecting rod 17 into the positioning groove 20. When the connecting rod 17 is blocked by the positioning plate 21 and cannot move, the worker steps on one end of the moving rod 22, causing the pressing block 23 to move away from the inclined block 24. The tension spring stretches and deforms, and the return spring pushes the inclined block 24 to move the positioning plate 21, causing the positioning plate 21 to retract into the positioning block. Inside 19, the support frame 16 is pushed, causing a connecting rod 17 to move past the positioning plate 21 to one end of the positioning groove 20. Then, the moving rod 22 is released, the tension spring contracts, and the pressing block 23 returns to its original position. The pressing blocks 23 at both ends of the pressing block 23 press the inclined blocks 24 to move, causing the positioning plate 21 to extend and limit the position of the connecting rod 17. Then, another empty transfer frame 4 is pushed to another positioning component 3. The handling robot 5, located on the same side of the exchange table 6 as the first machining center 8, transports the channel steel on the transfer frame 4 to the cutting robot 9. The clamping platform 10 on one side clamps and fixes the steel. The cutting robot 9 performs flame cutting on the clamping platform 10. The waste generated from the cutting falls into the collection box 14. The cut channel steel is transported to the first machining center 8 by the transport robot 1 5 for screw hole processing. After processing, the transport robot 1 5, located on the same side of the exchange platform 6 as the first machining center 8, transports the channel steel to the exchange platform 6 for placement. The limiting slot 7 limits the channel steel. During the process of transporting the channel steel to the exchange platform 6, the channel steel rotates 90 degrees. Then, another transport robot 1 5 transports the channel steel on the exchange platform 6 to the second machining center 15. The second machining center 15 performs shaft hole processing on the channel steel. After processing, the shaft hole is transported by the transport robot 1 5 to the clamping platform 10 on one side of the second machining center 15 for clamping and fixing. Then, the transport robot 2 12 places the roller shaft on the hopper 13 onto the channel steel and welds the roller shaft onto the channel steel by the welding robot 11. Then, the transport robot 1 5 transports the processed channel steel to the transfer frame 4 on one side of the second machining center 15 for stacking and storage.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
