Description

Technical Field

[0001] The utility model relates to the technical field of metal plate cutting, in particular to a laser cutting device for metal plates capable of being pushed. Background Art

[0002] When processing signs and labels, a cutting device is needed to cut the metal sheets, among which laser cutting machines are the most common.

[0003] After searching, it was found that the prior art, such as the Chinese patent (grant number: CN218476181U), discloses a laser cutting device for the production of logo signs. By starting the servo motor to drive the bidirectional threaded rod to rotate, the threaded blocks on the left and right sides move toward each other, and the pull rope connected to the threaded block pulls the movable plate down and compresses the reset spring. The limit plate moves down until it contacts the top of the logo sign and then stops moving. At this time, the threaded blocks on both sides continue to move toward each other, and the pull rope pulls the limit frames on the left and right sides to move toward each other until they contact the logo sign, thereby limiting the left and right sides of the logo sign, which can effectively prevent the logo sign from shifting during cutting and has a good fixing effect.

[0004] However, when cutting metal plates, the above patent requires workers to install the metal plates on the fixing base one by one, which lacks work continuity, is inefficient, and wastes time, so improvements are needed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pushable metal sheet laser cutting device, which solves the problems mentioned in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A pushable metal sheet laser cutting device comprises a cutting table, an inverted U-shaped bracket is fixed to the top of the cutting table near one end, the lower ends of two legs of the bracket are fixed to the cutting table, and a laser cutting machine is installed on the lower surface of the top plate, a height-adjustable hopper is arranged on the top of the cutting table, the upper and lower ends of the hopper are open, and a pushing gap is left between the lower end of the hopper and the cutting table, a pushing mechanism for pushing the metal sheet in the hopper is installed on the top of the cutting table near the other end, and the hopper is located between the pushing mechanism and the laser cutting machine.

[0008] In order to adjust the height of the hopper, two symmetrically arranged screws are fixed to the top of the cutting table near its front and rear sides, and ear plates are fixed to the front and rear sides of the top of the hopper. A circular hole that slides with the screw is vertically opened on the ear plate, and a nut is threadedly installed on the screw, and the nut rests on the bottom of the ear plate.

[0009] Specifically in the utility model, the pushing mechanism includes a cylinder, an L-shaped connecting plate, and a pushing plate. The bottom of the cylinder is installed on the top of the cutting table through a mounting frame. The support legs of the connecting plate are arranged upward and the sides are fixed to the free end of the cylinder piston rod. The bottom plate of the connecting plate faces the hopper and is fixed to the pushing plate. The cylinder pushes the pushing plate to slide in the pushing gap.

[0010] In order to better guide the metal sheet, two symmetrically arranged guide plates are fixed on the top of the cutting table. The guide plates are arranged along the working direction of the pushing mechanism and are located at the two side edges of the lower end of the hopper.

[0011] In order to prevent the metal sheet from being pulled out by the friction between the push plate and the metal sheet when the cylinder returns, two symmetrically arranged baffles are fixed on the top of the cutting table, and the baffles are located on the side of the hopper close to the pushing mechanism.

[0012] Compared with the prior art, the utility model has the following beneficial effects: multiple metal plates are stacked in a hopper, and the cylinder can drive the push plate to push each metal plate to the bottom of the laser cutting machine in turn for cutting, so that workers do not need to place the metal plates one by one under the laser cutting machine, which is more labor-saving and time-saving.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-6 The utility model provides a pushable metal sheet laser cutting device, comprising a cutting table 1, an inverted U-shaped bracket 2 is fixed to the top of the cutting table 1 near one end thereof, the lower ends of two legs of the bracket 2 are fixed to the cutting table 1, a laser cutting machine 3 is installed on the lower surface of the top plate, a hopper 4 with adjustable height is arranged on the top of the cutting table 1, the upper and lower ends of the hopper 4 are opened, a pushing gap is left between the lower end of the hopper 4 and the cutting table 1, a pushing mechanism for pushing the metal sheet M in the hopper 4 is installed on the top of the cutting table 1 near the other end thereof, and the hopper 4 is located between the pushing mechanism and the laser cutting machine 3.

[0022] In order to adjust the height of the hopper 4, two symmetrically arranged screws 5 are fixed to the top of the cutting table 1 near its front and rear sides, and ear plates 6 are fixed to the front and rear sides of the top of the hopper 4. The ear plates 6 are vertically provided with circular holes that slide with the screws 5. Nuts 7 are threadedly installed on the screws 5, and the nut 7 rests on the bottom of the ear plates 6.

[0023] Specifically in the utility model, the pushing mechanism includes a cylinder 8, an L-shaped connecting plate 9, and a pushing plate 10. The bottom of the cylinder 8 is installed on the top of the cutting table 1 through a mounting frame. The support legs of the connecting plate 9 are set upward and the sides are fixed to the free end of the piston rod of the cylinder 8. The bottom plate of the connecting plate 9 faces the hopper 4 and is fixed to the pushing plate 10. The cylinder 8 pushes the pushing plate 10 to slide in the pushing gap.

[0024] In order to better guide the metal sheet M, two symmetrically arranged guide plates 11 are fixed on the top of the cutting table 1. The guide plates 11 are arranged along the working direction of the pushing mechanism and are located at the two side edges of the lower end of the hopper 4.

[0025] In order to prevent the metal sheet M from being pulled out by the friction between the push plate 10 and the metal sheet M when the cylinder 8 returns, two symmetrically arranged baffles 12 are fixed on the top of the cutting table 1, and the baffles 12 are located on the side of the hopper 4 close to the pushing mechanism.

[0026] The working principle of the utility model is described in detail below: according to the thickness of the metal sheet M to be cut, the nut 7 is rotated up and down to make the nut 7 move up and down along the screw 5, the nut 7 moves upward, pushes the hopper 4 upward, and increases the pushing gap, the nut 7 moves downward, and reduces the pushing gap through the gravity of the hopper 4 until the pushing gap is slightly larger than the thickness of the metal sheet M to be cut, which can be suitable for metal sheets M of different thicknesses. Then, multiple metal sheets M can be stacked in the hopper 4. At this time, the bottom metal sheet is against the cutting table 1, the cylinder 8 is started, the piston rod moves, and through the connecting plate 9, the push plate 10 is pushed to move below the hopper 4, and is guided by the guide plate 11 until the bottom metal sheet M is pushed to the laser cutting machine 3. Below, cutting is carried out. The specific structure and working principle of the laser cutting machine 3 are existing technologies and will not be repeated in the present utility model. After the lowest metal sheet M is pushed out of the hopper 4, the remaining metal sheets M in the hopper 4, the lowest metal sheet M will automatically fall on the bottom plate of the connecting plate 9. When the cylinder 8 is returned, the baffle 12 will block the metal sheet M on the bottom plate of the connecting plate 9 to prevent the metal sheet M from being brought out. When the piston rod of the cylinder 8 is returned, the metal sheet M on the connecting plate 9 will automatically fall on the cutting table 1 by gravity. By repeating the above operations, continuous cutting of each metal sheet M can be achieved, and when the latter metal sheet M is pushed to the bottom of the laser cutting machine 3, the previous metal sheet M and debris will be pushed away from the cutting table 1.

[0027] Finally, compared with the prior art, the most important contribution of the present invention is that multiple metal sheets M are stacked in the hopper 4, and the cylinder 8 can drive the push plate 10 to push each metal sheet M to the bottom of the laser cutting machine 3 in turn for cutting. In this way, there is no need for workers to place the metal sheets M one by one under the laser cutting machine 3, which is more labor-saving and time-saving.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
