Description

Technical Field

[0001] This utility model relates to the field of cutting, and more specifically, it relates to a high-precision laser cutting machine for flat-mouthed thermos cups. Background Technology

[0002] In the production of thermos cups, metal sheets are welded into tubular shapes, cut, and then formed using a hydroforming machine. To ensure the precision of the thermos cup, the rim and bottom need to be cut after hydroforming to remove excess metal. This is mostly done using a laser cutting machine. Existing laser cutting machines generally include a frame, a worktable with a laser cutter and a control mechanism that drives the laser cutter to move along the X and Z axes, a rotating shaft connected to the worktable, and a drive mechanism inside the frame that rotates the shaft. A lower mold matching the shape and size of the thermos cup's inner cavity is mounted on the shaft. A lifting plate and a lifting mechanism that drives the lifting plate are also located on the worktable. An upper mold is rotatably connected to the lifting plate. When laser cutting the thermos cup, a worker or robot inserts the thermos cup blank into the lower mold, which supports the thermos cup. Then, the lifting mechanism drives the upper mold to descend until it contacts the thermos cup. The laser cutter is then moved to a suitable position by a control mechanism to cut the thermos cup. During this process, the drive mechanism rotates the shaft, which in turn rotates the thermos cup, allowing the laser cutter to cut the rim or bottom of the cup. The waste material cut off near the upper mold is usually removed when the thermos cup is replaced, while the waste material near the lower mold is usually placed on the shaft. To improve production efficiency, this waste material is often not processed immediately but is removed together after it has accumulated to a certain extent. Since the waste material consists of ring-shaped metal sheets with sharp cut edges, workers are prone to cuts when cleaning it, posing a certain safety hazard.

[0003] Based on the above, the purpose of this utility model is to provide a high-precision laser cutting machine for thermos cups to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a high-precision laser cutting machine for thermos cups. This invention involves setting a cutter and a pusher plate within the shadow area of ​​the lower mold. When the waste ring falls and surrounds both, a pushing mechanism drives the pusher plate to move away from the cutter. During this process, both ends of the waste ring will come into contact with the pusher plate and the cutter respectively and be stretched and tightened. Under the action of subsequent thrust, the waste ring will be cut off by the cutter and pushed out by the pusher plate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-precision laser cutting machine for thermos cups, comprising a frame, a worktable on the frame, a rotating shaft rotatably connected to the worktable, a lower mold on the rotating shaft, the diameter of the rotating shaft being smaller than that of the lower mold, a cutter fixedly connected to the worktable and a push plate slidably connected to the worktable, the push plate being arc-shaped, the cutter and the push plate being located on opposite sides of the rotating shaft, both the cutter and the push plate being located within the projection range of the lower mold, and a pushing mechanism for driving the push plate to move on the worktable.

[0006] By adopting the above technical solution, during the process of laser cutting flat-edge cups, the waste material near the rotating shaft will slide down. Since both the cutter and the push plate are located within the projection range of the lower mold, the falling waste material will surround them. At this time, the push plate is driven by the pushing mechanism to push away from the cutter. During this process, both ends of the waste material will come into contact with the push plate and the cutter respectively and be stretched and tightened. Under the action of subsequent thrust, the waste material ring will be cut off by the cutter and pushed out by the push plate. With this setting, workers do not need to manually clean the waste material ring fitted on one side of the rotating shaft, which reduces the labor intensity of workers and also reduces the probability of workers being injured while handling waste.

[0007] The present invention is further configured such that: the pushing mechanism includes a cylinder fixedly connected to the worktable, and the extended end of the cylinder is fixedly connected to the push plate.

[0008] The present invention is further configured such that a protective cover is fixedly connected to the side of the workbench away from the cutter.

[0009] The present invention is further configured such that: a discharge trough corresponding to the position of the protective cover is provided on the workbench.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This invention features a cutter and a push plate positioned within the shadow area of ​​the lower mold. When the waste ring falls and surrounds both, a pushing mechanism drives the push plate away from the cutter. During this process, both ends of the waste material come into contact with the push plate and the cutter respectively and are stretched and tightened. Under the subsequent thrust, the waste ring is cut off by the cutter and pushed out by the push plate. The pushed-out waste material is blocked by a protective cover and then discharged through a discharge chute. Workers do not need to manually clean the waste ring fitted on one side of the rotating shaft, reducing the workload for workers and the probability of injury while handling waste.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "provided with," "set up / connected," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A high-precision laser cutting machine for flat-edge thermos cups, such as Figures 1-3As shown, the machine includes a frame 1, on which a worktable 2, a rotating shaft 3, a drive mechanism, a lower mold 4, a laser cutter 10, a control mechanism 11, an upper mold 13, and a lifting mechanism 12 are mounted. The rotating shaft 3, drive mechanism, lower mold 4, laser cutter 10, control mechanism 11, upper mold 13, and lifting mechanism 12 on the laser cutting machine are all mature existing technologies. No improvements have been made to these components and mechanisms in this case, so their structure and operating principle will not be described in detail.

[0021] The lower mold 4 is mounted on the rotating shaft 3, the diameter of which is smaller than that of the lower mold 4. The worktable 2 is provided with a cutter 5 fixedly connected to it and a push plate 6 slidably connected to it. The push plate 6 is arc-shaped. For easy installation and driving, the lower ends of the cutter 5 and the push plate 6 are respectively fixedly connected to the mounting plate 13 and the slide 14. The mounting plate can be fixed to the worktable 2 by bolts threaded to the worktable. When the cutter 5 needs to be ground or replaced, the mounting plate can be removed by unscrewing the bolts. Two slide rails are installed on the worktable 2. The two ends of the slide are slidably connected to the two side slide rails respectively. The cutter 5 and the push plate 6 are located on both sides of the rotating shaft 3. Both the cutter 5 and the push plate 6 are located within the projection range of the lower mold 4. The worktable 2 is provided with a pushing mechanism 7 that drives the push plate 6 to move.

[0022] Furthermore, the pushing mechanism 7 includes a cylinder fixedly connected to the worktable 2. The extended end of the cylinder is fixedly connected to the slide. Since the cutting allowance during the processing of thermos cups is not particularly large, the width of the cut waste ring is often small, and the waste is all thin metal sheets with a small thickness. Selecting a cylinder with a large output force can drive the push plate and cooperate with the cutter to cut off and push out the waste.

[0023] Furthermore, a protective cover 8 is fixedly connected to the side of the workbench 2 away from the cutter 5, and the protective cover is provided with a relief groove for the waste material to slide down.

[0024] Furthermore, the workbench 2 is provided with a discharge chute 9 corresponding to the position of the protective cover 8, and the end of the discharge chute 9 away from the protective cover 8 extends outside the frame 1.

[0025] Working principle: During the process of laser cutting flat-edge cups, the waste material near the rotating shaft 3 will slide down. Since the cutter 5 and the push plate 6 are both located within the projection range of the lower mold 4, the falling waste material will surround them. At this time, the cylinder drives the push plate 6 to push away from the cutter 5. During this process, the two ends of the waste material will abut against the push plate 6 and the cutter 5 respectively and be stretched and tightened. Under the action of subsequent thrust, the waste material ring will be cut off by the cutter 5 and pushed out by the push plate 6. The pushed-out waste material will fly into the protective cover 8 and then be discharged along the trajectory of the discharge groove 9. With this setting, the worker does not need to manually clean the waste material ring fitted on one side of the rotating shaft 3, which reduces the worker's labor intensity and the probability of worker being injured while handling waste.

[0026] Further, a position sensor, such as a proximity sensor or infrared sensor, can be installed on the mounting plate. A controller, such as a microcontroller or PLC controller, can be placed on the frame 1. Both the sensor and the cylinder are electrically connected to the PLC controller. These components are then electrically connected to the power supply on the laser cutting machine 10. When the sensor detects waste material falling to the designated position, it transmits the detected signal to the controller. The controller then drives the cylinder's extension end to extend and retract, thus achieving precise waste material feeding as described in this invention. This setup also prevents waste material from getting stuck between the push plate 6 and the rotating shaft 3 during the cylinder's erratic movement. Driving the cylinder through a controller and sensor is a mature existing technology, which will not be elaborated upon here.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
