Description

Technical Field

[0001] The utility model belongs to the technical field of steering lower bracket production equipment, in particular to a laser cutting device for the steering lower bracket. Background Art

[0002] The bogie, like a human leg, is a core component of a rail vehicle's running gear. Its lower bracket can be cut and shaped using a laser cutting machine. Laser cutting machines focus laser light emitted from a laser source through an optical system into a high-power, high-density laser beam. The laser beam strikes the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Since the conventional steering lower bracket uses a laser to cut the grid-shaped bracket with many internal slots, the resistance to discharging the cut waste when it falls is relatively large, and the slot space is small, making it difficult to reach in and clean it, which makes it difficult to discharge the waste using a conventional laser cutting machine.

[0004] To this end, we proposed a laser cutting device for the steering lower bracket to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that it is difficult for a conventional laser cutting machine for a steering lower bracket to discharge waste, and to propose a laser cutting device for a steering lower bracket.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A laser cutting device for a steering lower bracket includes a laser cutter, wherein the interior of the laser cutter is fixedly connected to a grid, and an elastic tray is movably provided at the bottom of the grid. The rear portion of the elastic tray is fixedly connected to the rear portion of the grid, and the front portion of the elastic tray is fixedly connected to the elastic frame, and the elastic tray is tilted downward. An external container is placed on the front lower side of the elastic tray, and then the raw materials of the target steering lower bracket components are placed on the grid and processed by laser cutting. The waste blown downward by the laser cutting falls through the gaps in the grid onto the elastic tray and is discharged into the external container through the elastic tray. When the external container needs to be picked up, the elastic frame is manually pulled upward and then released to vibrate the elastic frame, and the elastic frame acts on the elastic tray, reducing the sliding resistance of the waste on the elastic tray, making it easier for laser cutting to discharge the waste.

[0008] Preferably, the lower end of the laser cutting machine is provided with a support leg, which increases the stability of the laser cutting machine.

[0009] Preferably, the grid frame includes toothed grid plates, connecting rods, and baffles. The toothed grid plates are evenly distributed, the connecting rods are fixedly inserted into the upper portions of the toothed grid plates, and the baffles are symmetrically fixedly connected to the sides of the connecting rods. The toothed grid plates support the target steering lower bracket, and the waste generated by cutting falls downward through the gaps between the toothed grid plates onto the elastic tray, facilitating heat dissipation and waste removal of the component raw materials of the target steering lower bracket.

[0010] Preferably, the elastic tray includes a connecting plate, an elastic plate, and a baffle, wherein the connecting plate is fixedly connected to the rear of the elastic plate, and the baffle is symmetrically fixedly connected to the front upper end of the elastic plate. When the waste falls onto the elastic plate through the grid, the elastic plate guides the waste downward, and the baffle guides the waste toward the center, so that the waste is concentrated in the external container, facilitating unloading.

[0011] Preferably, the elastic frame includes a connecting bar and a spring sheet, one end of which is fixedly connected to the connecting bar. Pulling the spring sheet upwards away from the end of the connecting bar and then releasing the spring sheet causes the spring sheet to vibrate in the vertical direction. The vibration acts on the connecting bar through the spring sheet, which in turn acts on the retaining bar through the connecting bar, thereby driving the elastic plate to vibrate.

[0012] Preferably, the elastic frame further comprises a weight block, which is fixedly connected to the end of the elastic piece facing away from the connecting strip. The weight block is used to increase the kinetic energy storage amount and extend the vibration time of the elastic piece.

[0013] Preferably, the elastic frame further comprises a pull button, the lower end of which is fixedly connected to the upper end of the weight block. Pulling the pull button upward causes the pull button to act upward on the weight block, causing the weight block to drive the elastic sheet to deform upward, and then releasing the pull button facilitates the operation of the weight block and the elastic sheet to vibrate up and down.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Place the additional container on the front lower side of the elastic tray, then place the raw materials of the components of the target steering lower bracket on the grid, and process them through laser cutting. The waste blown downward by the laser cutting falls through the gap of the grid onto the elastic tray, and is discharged into the additional container through the elastic tray. When the additional container needs to be picked up, pull the elastic frame upward and then release it to make the elastic frame vibrate. The elastic frame acts on the elastic tray through the elastic frame, reducing the sliding resistance of the waste on the elastic tray, making it easier for laser cutting to discharge the waste.

[0016] 2. Use the toothed grating to support the target steering lower bracket, and the waste formed by cutting will fall down to the elastic tray through the gap between the toothed gratings, which is convenient for heat dissipation and waste discharge of the raw materials of the target steering lower bracket.

[0017] 3. When the waste falls onto the elastic plate through the grid, the elastic plate guides the waste downward, and the baffle guides the waste toward the center, so that the waste is concentrated in the external container, which is convenient for unloading.

[0018] 4. Pull the spring upwards towards one end of the connecting bar, then release the spring to make it vibrate up and down. The vibration acts on the connecting bar through the spring, and acts on the baffle bar through the connecting bar, which facilitates the vibration of the elastic plate.

The toothed grid plates 21 and connecting rods 22 are fixedly installed inside the laser cutting machine 1. The toothed grid plates 21 are evenly distributed, the connecting rods 22 are fixedly inserted in the upper part of the toothed grid plates 21, and the baffles 23 are symmetrically fixed to the sides of the connecting rods 22. The toothed grid plates 21 support the target turning to the lower bracket, and the waste formed by cutting falls downward through the gaps between the toothed grid plates 21 and onto the elastic tray 3.

[0028] Reference Figure 1 、 2 3. The elastic tray 3 includes a connecting plate 31, an elastic plate 32, and a stop bar 33. The connecting plate 31 is fixedly connected to the rear of the toothed grid plate 21 and the connecting rod 22. The connecting plate 31 is fixedly connected to the rear of the elastic plate 32. The stop bar 33 is symmetrically fixedly connected to the front upper end of the elastic plate 32. When waste passes through the grid 2 and falls onto the elastic plate 32, the waste is guided downward by the elastic plate 32 and guided toward the center by the stop bar 33, so that the waste is concentrated in the external container.

[0029] Reference Figure 1 、 3 4, the elastic frame 4 includes a connecting bar 41 and a spring piece 42. The connecting bar 41 is fixedly connected to the upper end of the stop bar 33, and one end of the spring piece 42 is fixedly connected to the connecting bar 41. Pulling the spring piece 42 upward away from the end of the connecting bar 41 and then releasing the spring piece 42 causes the spring piece 42 to vibrate in the vertical direction. The vibration is applied to the connecting bar 41 through the spring piece 42, and then to the stop bar 33 through the connecting bar 41, causing the stop bar 33 to drive the elastic plate 32 to vibrate.

Then releasing the pull button 44 causes the weight 43 and the elastic sheet 42 to vibrate up and down.
