Description

Technical Field

[0001] The utility model relates to auxiliary manufacturing equipment for a lower disc of a thermos cup, in particular to a mechanism for sucking waste residue after sheet metal is laser cut into lower discs. Background Art

[0002] The bottom disc of the thermos cup is a part of the bottom of the thermos cup. Its current processing technology is to process and transport it in strips first, which cannot fully utilize the raw materials and requires a lot of input from production personnel. At the same time, the matching blanking molds have many types of corresponding molds due to the variety of products, which are easy to damage and have high maintenance, storage and repair costs. In addition, the noise decibel of stamping and blanking affects the environment, the installation of molds is labor-intensive and requires certain technical requirements, and cutting has safety hazards. In addition, the production plan will not be continued due to mold and equipment failures, etc. These are the main causes of high costs. The initial test of laser cutting found slag and splashing, which caused product quality problems. Utility Model Content

[0003] The utility model aims to provide a lower disc cutting waste residue suction mechanism, and solves the technical problem of how to avoid residue hanging and splashing when laser cutting sheet metal is used to make the lower disc of a thermos cup.

[0004] The lower wafer cutting waste slag suction mechanism includes a slag suction pipe, a connecting pipe, a negative pressure exhaust fan, and an electromagnet; the slag suction pipe is hollow inside, and an electromagnet is installed on its side wall. The suction port of the slag suction pipe is aligned with the laser cutting head, and the discharge port of the slag suction pipe cooperates with the negative pressure exhaust fan through the connecting pipe.

[0005] The top of the slag suction pipe is open, and the bottom is provided with threads, and the slag suction pipe is connected with the connecting pipe through the threads.

[0006] The electromagnet is installed at a position close to the opening of the slag suction pipe by means of screws.

[0007] The electromagnets are provided in pairs and are arranged oppositely on two sides of the slag suction pipe.

[0008] The beneficial effect of the utility model is as follows: by arranging a slag suction pipe directly below the laser cutting head, when the laser cutting head cuts the sheet metal, the waste slag generated can fall into the slag suction pipe, and by matching the electromagnet on the slag suction pipe, it is ensured that when the waste slag is generated, it can be sucked into the slag suction pipe to avoid the waste slag from spraying and damaging the lower disc. The mechanism solves the problems of slag hanging and splashing in laser cutting, and at the same time solves the problem that the raw materials no longer need to be processed and transported in strips, and the cost of manufacturing, fragile, maintenance, storage and repair positions of blanking molds is eliminated. At the same time, the stamping and blanking optimizes the working environment and eliminates the position of installing molds, which reduces labor intensity, ensures safe production and eliminates hidden dangers. The raw materials can be quickly made into any shape by using automatic typesetting of large and small circles, and only one typesetting operator is required, thereby saving raw materials, and the production plan will no longer be unable to continue due to mold and equipment failures; in addition, the cost of raw material strip processing is saved, and the scraps are fully utilized through typesetting, so as to achieve a purified production environment, simple and flexible, reduce costs and increase efficiency, and solve the problem of high manufacturing costs.

[0017] Please refer to Figures 1 to 3 The lower disc cutting waste slag suction mechanism in the figure is mainly to ensure that when the laser cutting head performs circular cutting on the sheet metal to form the lower disc, the waste slag generated by the cutting will not damage the lower disc or the sheet metal. The mechanism designed in this case is different from the simple suction mechanism. It changes the current traditional manufacturing process of the lower disc of the thermos cup, thereby optimizing the original sheet metal punching molding to cutting molding, thereby avoiding the preparation of lower discs of various specifications.

[0018] The slag suction pipe 1 in the figure is a conventional hollow metal pipe, which has an opening at the top and a thread 11 at the bottom, so that the waste slag can easily fall into the opening. At the same time, the thread 11 is convenient for screwing with the connecting pipe 4. The above opening and the cutting position of the laser cutting head are kept at the position directly below. The bottom thread 11 part forms a discharge port and is assembled with the negative pressure exhaust fan 3 through the connecting pipe 4, so that the waste slag is sucked into the negative pressure exhaust fan 3 for storage. The slag suction pipe 1 is used to facilitate the installation of the electromagnet 2, and its side wall is sliced, and the electromagnet 2 is installed on the slag suction pipe 1 by screws. The above-mentioned electromagnet 2 is designed with two pieces in total and arranged on the slag suction pipe 1 in a symmetrical manner. The electromagnet 2 in this case adopts conventional components and structures, which can be adjusted as needed. When the laser working head starts cutting, the electromagnet 2 begins to conduct electricity and generate magnetism, thereby adsorbing the waste slag. When the cutting is completed, it begins to disconnect and eliminate magnetism, so that the waste slag can fall, avoiding the accumulation of waste slag.

[0019] The negative pressure exhaust fan 3 in the figure is a conventional component, which starts to work when the laser cutting machine is working, and uses suction to suck the waste residue that was originally running around into the residue suction pipe 1. In practical applications, the negative pressure exhaust fan 3 can adopt other styles and structures.

[0020] The connecting pipe 4 in the figure is a conventional component, which is required to have a higher heat resistance, and the slag suction pipe 1 also needs to have a corresponding heat resistance.
