Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping equipment for processing refrigerator workpieces. Background Technology

[0002] Refrigerators are indispensable appliances in modern households, used for food preservation and storage, greatly extending the shelf life of food. The common refrigeration principle uses a compressor to compress gaseous refrigerant into a high-temperature, high-pressure gas. The gas then enters the condenser, where it exchanges heat with the outside air through heat sinks, cooling and condensing into a liquid. The liquid refrigerant then passes through a capillary tube for throttling and pressure reduction, becoming a low-temperature, low-pressure liquid that flows into the evaporator. In the evaporator, the low-temperature, low-pressure liquid refrigerant rapidly vaporizes, absorbing heat from inside the refrigerator and lowering the temperature inside. The vaporized refrigerant is then drawn back into the compressor, starting a new cycle, and this cooling process continues. Stamping equipment is required in the manufacturing process of refrigerator components.

[0003] Stamping equipment is a machine that uses pressure to stamp metal or other materials. It utilizes a mechanical transmission system to convert the rotary motion of a motor into the reciprocating linear motion of a slide, thereby stamping the material. Mechanical presses offer relatively high stamping precision and are suitable for stamping parts with strict dimensional accuracy requirements. However, after prolonged use, key components of stamping equipment, such as the machine body or slide, will experience wear, affecting the slide's motion accuracy. Wear on the slide guide rails leads to a decrease in the linearity of the slide's movement, further impacting stamping precision. Current solutions involve regularly inspecting and maintaining the stamping equipment for precision, and promptly replacing worn parts. For critical components like the slide guide rails, wear-resistant materials or surface treatment techniques, such as chrome plating on the guide rail surface, can be used to improve wear resistance. However, when stamping thin metal sheets, if the material itself is of poor quality, such as containing impurities, inclusions, or surface rust, debris will be generated during the stamping process. The accumulation of this debris will affect the stamping quality of the product, thus reducing the product yield. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a stamping equipment for processing refrigerator workpieces, aiming to improve the problem that the accumulation of debris in the prior art will affect the stamping quality of the product and thus reduce the product yield.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a stamping device for processing refrigerator workpieces, comprising a housing 1, an extraction fan 3 fixedly connected to the left side of the inner bottom wall of the housing 1, an extraction pipe 4 connected to the front right end of the extraction fan 3, and a purification box 5 connected to the right end of the extraction pipe 4, so that the gas and flue gas are purified through the purification box 5. A connecting pipe 6 is connected to the front right end of the purification box 5, and a filter box 7 is connected to the right end of the connecting pipe 6, so that the debris is filtered through the filter box 7. A filter plate 8 is slidably connected to the front middle of the filter box 7, and the filter plate 8 can be removed by pulling it. To complete the cleaning, a connecting pipe 9 is connected to the top rear side of the filter box 7, and an extraction head 10 is connected to the front end of the connecting pipe 9. The outer wall of the extraction head 10 is fixedly connected to the rear side of the inner wall of the outer shell 1. Thus, under the fixation of the extraction head 10, the debris generated by the stamping is extracted. A stamping device 11 is fixedly connected to the inner bottom wall of the outer shell 1, and a lower template 12 is fixedly connected to the middle of the outer shell 1. By starting the stamping device 11, the lower template 12 is used to complete the stamping work of the parts. Fixing mechanisms 2 are provided on both the left and right sides of the lower template 12. The fixing mechanisms 2 are used to improve the fitting range and fixing effect of the fixed parts of the device.

[0032] Specifically, the part to be processed is placed on the upper surface of the lower template 12, and then the stamping device 11 is started to perform the stamping operation. During the stamping process, in order to ensure the cleanliness and safety of the working environment, the extraction fan 3 is started. The operation of the extraction fan 3 drives the extraction head 10 to start working. The extraction head 10 is responsible for drawing in air, thereby effectively sucking in the debris particles generated during the stamping process. These debris particles are then drawn into the interior of the filter box 7, realizing the centralized collection of these debris particles. In the filter box 7, the filter plate 8 can block these debris particles, causing them to remain on the upper surface of the filter plate 8. At the same time, the fumes generated during the stamping operation are also extracted by the extraction head 10. The extracted fumes pass through the purification box 5, where the filter further removes impurities from the fumes, ensuring that the discharged gas is clean. Finally, the purified gas is discharged into the external environment by the extraction fan 3, which improves the safety of the working environment, prevents the accumulation of debris, and avoids adverse effects on the stamping quality of the product. In addition, the airflow generated by the extraction fan 3 can also effectively cool down the parts being stamped, which not only helps to protect the parts from heat damage, but also improves the efficiency of stamping.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 2 includes two connecting plates 201. The bottom of the adjacent sides of the two connecting plates 201 are fixedly connected to the left and right sides of the lower template 12, respectively. An electric push rod 202 is fixedly connected inside the connecting plate 201, so that the electric push rod 202 is supported by the fixing of the connecting plate 201. One end of the electric push rod 202 is fixedly connected to the mounting plate 203. Bolts 204 are threadedly connected to the front and rear ends of one side of the mounting plate 203, so that the fixing clamp 206 can be replaced by rotating the bolts 204, thereby facilitating the adaptation of parts of different specifications. One end of the bolt 204 is threadedly connected to the fixing clamp 206. Multiple rubber pillars 207 are fixedly connected to the adjacent sides of the two fixing clamps 206, so that the fixing effect of the parts is improved by the connection of the rubber pillars 207. The multiple rubber pillars 207 are arranged in an equidistant ring.

[0034] Specifically, by rotating the bolt 204, one end of the bolt 204 can be connected to and disconnected from the fixing clamp 206. This allows the stamping equipment to select the appropriate fixing clamp 206 according to the different stamping parts requirements. Subsequently, under the driving action of the electric push rod 202, the mounting plate 203 will move to one side of the part under the push of one end of the electric push rod 202, thereby fixing the part, improving the adaptability range during part processing, and ensuring the stability of the part processing.

[0035] Reference Figure 1 , Figure 4 and Figure 5The fixing mechanism 2 also includes multiple rubber rings 205, the inner walls of which are fixedly connected to the middle of the corresponding bolts 204; a square groove 19 is provided on the rear side of the outer shell 1, and an observation window 20 is fixedly installed inside the square groove 19; a control switch 13 is fixedly connected to the right side of the outer shell 1, and the control switch 13 is electrically connected to the extraction fan 3, the stamping device 11 and the electric push rod 202 respectively.

[0036] Specifically, the fixing of the rubber ring 205 reduces the rotational damage of the bolt 204 to the mounting plate 203. The opening of the square groove 19 allows for the installation of the observation window 20, which facilitates the observation of the stamping of the parts. The control switch 13, which is electrically connected to the extraction fan 3, the stamping device 11 and the electric push rod 202 respectively, enables the control switch 13 to open and close the device.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A rubber ring 14 is fixedly connected to the top of the outer wall of the connecting pipe 9, and the outer wall of the rubber ring 14 is fixedly connected to the rear side of the extraction head 10; a handle 15 is fixedly connected to the front side of the filter plate 8, and a rubber sleeve 16 is fixedly connected to the middle of the handle 15; two connecting seats 17 are fixedly connected to the front and rear sides of the outer shell 1, and a support column 18 is fixedly connected inside the connecting seat 17.

[0038] Specifically, the rubber ring 14 is used to protect the connection at the top of the connecting pipe 9, the handle 15 makes it easy to pull out and replace the filter plate 8, and the connection seat 17 and the support column 18 are fixed to improve the stability of the device during operation.

[0039] Working principle: When starting to use, the part is placed on top of the lower template 12, and the stamping device 11 is started to perform the stamping operation. Then, by starting the extraction fan 3, the extraction head 10 extracts air, so that the stamping debris particles generated during the operation of the stamping device 11 are drawn into the interior of the filter box 7 by the extraction head 10, and the debris is collected uniformly. Then, under the obstruction of the filter plate 8, the debris particles are left on the top of the filter plate 8. At the same time, the flue gas generated during stamping is also extracted by the extraction head 10. After filtering the debris, the flue gas is filtered through the purification box 5 and then discharged by the extraction fan 3. This improves environmental safety and avoids the situation where debris accumulation affects the stamping quality of the product. At the same time, the flowing air can cool the stamped parts, thereby improving the forming efficiency.

[0040] Furthermore, by rotating the bolt 204, one end of the bolt 204 can be connected and disconnected from the fixing clamp 206, allowing the device to select the corresponding fixing clamp 206 according to different stamping parts. Subsequently, driven by the electric push rod 202, the mounting plate 203 is pushed to one side of the part by one end of the electric push rod 202, thereby achieving the purpose of fixing the part. This improves the adaptability of fixing during part processing and ensures the stability of part processing.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
