Description

Technical Field

[0001] The utility model relates to a solar energy aluminum bar accessory forming and cutting machine, in particular to a cutting machine capable of automatically cutting aluminum bars of the same length. Background Art

[0002] Most areas in my country are suitable for the use of solar energy. Solar water heaters convert sunlight energy into thermal energy and heat water from low temperature to high temperature to meet people's hot water needs in life and production. Therefore, the production of solar energy is large, and the aluminum bars in solar accessories are needed in large quantities and must reach the same required length. Generally, manual operation is required when cutting aluminum bars. When the formed aluminum bars pass through the shear to the required length, workers cut them, which causes labor waste and increases production costs. Utility Model Content

[0003] The problem to be solved by the utility model is to be able to automatically cut aluminum bars of the same length.

[0004] In order to solve the above problems, the present invention is achieved through the following technical solutions:

[0005] An aluminum bar forming and cutting machine includes a workbench, an aluminum bar transport unit and a forming unit. The transport unit includes a mounting frame and a turntable. The turntable is rotatably connected to the mounting frame. The forming unit includes a motor, a mold and a chain. The motor is fixedly connected to the workbench. There are three groups of molds. Each group of molds includes an upper die and a lower die. One of the lower dies is fixedly connected to the motor shaft, and the other lower dies are connected by a chain. The mold is rotatably connected to the workbench. It is characterized in that it also includes a code detector, a cutting unit, and the length code detector It includes a code detector, which is rotatably connected to the workbench. The cutting part includes a CNC cylinder, a shearing door and a shearing knife. The shearing door is provided with an entrance, the shearing door is fixedly connected to the workbench, the CNC cylinder is fixedly connected to the upper part of the shearing door, the shearing knife is fixedly connected to the CNC cylinder, and the shearing knife is slidably connected to the shearing door. The code detector also includes a rubber ring, which is sleeved in a groove around the code detector shaft. The maximum diameter of the rubber ring is the same as the diameter of the code detector shaft, and the outermost ring side surface of the rubber ring is flush with the side surface of the shaft.

[0006] By adopting the above technical solution, the motor drives the lower die fixedly connected to its rotating shaft to rotate, and drives the other lower die to rotate through the chain, thereby driving the aluminum strip between the upper and lower die films to pass from the turntable where it is located first under the encoder shaft, driving the encoder shaft to rotate. The rubber ring sleeved on the encoder shaft can increase the friction between it and the aluminum strip. The side surface of the outermost circle of the rubber ring is flush with the side surface of the rotating shaft, which can ensure that the length of one rotation of the rubber ring is consistent with the length of one rotation of the rotating shaft, so that when the aluminum strip passes through the rubber ring, the number of circles driven by the rubber ring to rotate can be directly converted by the encoder into the length of the aluminum strip passing. The aluminum strip then passes between the upper and lower dies, and the upper and lower dies form and press it. The lower die drives the aluminum strip through the guillotine. When the code detector measures that the length of the aluminum strip passing is the required length, the CNC cylinder drives the guillotine to cut the aluminum strip, which can ensure that the cut aluminum strips are of the same length. This eliminates the need to arrange workers separately, saves resources, reduces costs, and makes the cut length more accurate.

[0007] Preferably, the mounting bracket further comprises a screw, the screw is threadedly connected to the mounting bracket, and the screw is rotationally connected to the turntable.

[0008] By adopting the above technical solution, the radius of the aluminum bar on the turntable gradually becomes smaller during the transmission process, and the head end of the aluminum bar on the turntable is not at the same height as the workbench. By turning the bolt to adjust the height of the turntable, the head end of the aluminum bar on the turntable is at the same height, so that the aluminum bar will not have creases and it is easier to transmit.

[0009] Preferably, a collection box is further included, which includes a movable box cover, a limit bar and a slope. The box cover is placed at an angle, located on the upper part of the box body, and is rotatably connected to the box body. A gap is left between the box cover and one side of the box body, and the formed and cut aluminum strips can just pass through the gap. The limit bar is located at the lower part of the movable box cover and is fixedly connected to the box body, and the slope is fixedly connected to the opening of the box body.

[0010] By adopting the above technical solution, the cut aluminum bars fall on the slope of the collection box and slide on the slope to the gap between the box body and the box cover. Aluminum bars of the correct length will fall into the collection box through the gap, and those that are too long will slide through the gap, thereby further screening the aluminum bars and improving their quality.

[0011] Preferably, the forming part includes a limiting ring, a screw and a limiting slide. A thread is provided in the groove around the limiting ring. The mold is rotatably connected to the limiting ring. The limiting slide is vertically fixedly connected to both sides of the workbench. A threaded hole is provided on the upper part of the limiting slide. The limiting ring is located in the limiting slide. The limiting ring is slidably connected to the limiting slide. The limiting slide and the limiting ring are threadedly connected with screws.

[0012] By adopting the above technical solution, the height of the upper pressing die can be adjusted to adjust the distance between the upper and lower pressing dies when pressing aluminum bars of different thicknesses or different specifications, so as to press aluminum bars of different thicknesses or different specifications.

[0013] Preferably, the code detector is fixedly connected to an L-shaped rod, the L-shaped rod is rotatably connected to the mounting frame, and the L-shaped rod is fixedly connected to the workbench via a tension spring.

[0014] By adopting the above technical solution, the L-shaped rod can be rotated for aluminum sheets of different thicknesses to adjust the gap between the encoder shaft and the workbench so that it can pass through aluminum sheets of different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS

The rubber ring The outermost circle side surface of 10 is flush with the side surface of the rotating shaft of the code detector 6. The motor 3 drives the lower pressure mold 5 fixedly connected to its rotating shaft to rotate, driving the other lower pressure molds 5 to rotate, thereby driving the aluminum strip between the upper and lower pressure films from the turntable 2 where it is located to first pass under the rotating shaft of the code detector 6, driving the rotating shaft of the code detector 6 to rotate. The rubber ring 10 sleeved on the rotating shaft of the code detector can increase its friction with the aluminum strip. The side surface of the outermost circle of the rubber ring 10 is flush with the side surface of the rotating shaft of the code detector 6, which can ensure that the length of one rotation of the rubber ring 10 is consistent with the length of one rotation of the shaft, so that when the aluminum strip passes through the rubber ring, the number of circles driven by the rubber ring 10 to rotate can be directly converted by the code detector 6 into the length of the aluminum strip passing. The aluminum strip then passes between the upper and lower pressure molds, and the upper and lower pressure molds press it. The lower pressure mold 5 drives the aluminum strip through the shear gate 8. When the code detector 6 measures that the length of the aluminum strip passing is the required length, the CNC cylinder 7 drives the shear knife 9 to cut the aluminum strip, which can ensure that the cut aluminum strips are of the same length.

A gap is left between the box cover 13 and one side of the box body 12. The formed and cut aluminum strips can just pass through the gap. The slope 14 is fixedly connected to the opening of the box body 12. The cut aluminum strips fall on the slope 14 of the collection box and slide on the slope 14 to the gap between the box body 12 and the box cover 13.

[0024] See Figure 2 The code detector is fixedly connected to an L-shaped rod 18, which is rotatably connected to the workbench. The L-shaped rod 18 is fixedly connected to the workbench with a tension spring 19. For aluminum sheets of different thicknesses, the L-shaped rod 18 can be rotated to adjust the gap between the rotating shaft of the code detector 6 and the workbench so that it can pass through aluminum sheets of different thicknesses.

[0025] Working principle: The motor 3 drives the lower pressing die 5 fixedly connected to its rotating shaft to rotate, and drives the other lower pressing dies 5 to rotate, thereby driving the aluminum strip between the upper and lower pressing films from the turntable 2 where it is located to first pass under the rotating shaft of the code detector 6, and rotate the L-shaped rod 18 to adjust the gap between the rotating shaft of the code detector 6 and the workbench so that it can pass through aluminum sheets of different thicknesses, driving the rotating shaft of the code detector 6 to rotate. The rubber ring 10 sleeved on the rotating shaft of the code detector can increase the friction between it and the aluminum strip. The side surface of the outermost circle of the rubber ring 10 is flush with the side surface of the rotating shaft of the code detector 6, which can ensure that the length of one rotation of the rubber ring 10 is consistent with the length of one rotation of the shaft, so that when the aluminum strip passes through the rubber ring, the number of circles driven by the rubber ring 10 can be directly converted by the code detector 6 into the length of the aluminum strip passing. It passes through the upper and lower dies, and the upper and lower dies form and press it. For aluminum bars of different thicknesses or different specifications that need to be pressed, the screw 16 can be turned up or down to adjust the height of the limit ring 15 in the limit groove 17 to adjust the distance between the upper and lower dies. For aluminum bars of different thicknesses or different specifications that need to be pressed, the lower die 5 drives the aluminum bar through the guillotine door 8. When the code detector 6 measures that the length of the aluminum bar is the required length, the CNC cylinder 7 drives the guillotine 9 to cut the aluminum bar, which can ensure that the cut aluminum bars are of the same length. The cut aluminum bars fall on the slope 14 of the collection box and slide on the slope 14 to the gap between the box body 12 and the box cover 13. The aluminum bars of the correct length will fall into the collection box from the gap, and those that are too long will slide through the gap.
