Embodiment Construction

[0056] The present invention discloses two methods for manufacturing counterweights. The difference between the two methods and the prior art is that they both include negative pressure and blown dry air in the manufacturing process to balance the counterweights. The steps in which drying is carried out; however, the exact manner in which drying is carried out varies.

[0057] refer to figure 1 , figure 2 , image 3 and Figure 4 , shows the manufacturing process of the first method for manufacturing the counterweight disclosed in the present invention.

[0058] first reference figure 1 , according to the pre-designed shape, weld the shell 10 of the counterweight with a plurality of metal plates; 10 has a filler port 15 for filling the core material; in addition, the top cover 12 matching the profile of the filler port 15 is processed for subsequent use.

[0059] Refer again figure 2 Fill the core material 11 into the counterweight shell 10; the core material 11 is co...

Abstract

The invention discloses a method for manufacturing a non-casting balancing weight, which comprises: firstly welding a plurality of metal plates into a shell, reserving a feeding port on the shell, filling core materials such as waste metal, gravel and waste residues into the shell, putting the balancing weight filled with the core materials into a decompression chamber for drying, pumping wet air in the decompression chamber by an extraction pump and simultaneously blowing dry air into the decompression chamber in the drying process, and sealing the feeding port after drying of the balancing weight to manufacture the balancing weight; or firstly sealing the feeding port before executing the drying step, and in the process of executing the drying step, utilizing the shell of the balancing weight to replace the decompression chamber, configuring an extract opening and an air inlet port on the shell, respectively connecting the extract opening and the air inlet port to the extraction pump and a dry air source, pumping the wet air in the shell of the balancing weight by the extraction pump while filling the dry air into the shell, and using less energy consumption to achieve better drying effect.

Description

technical field [0001] The present invention relates to a method for manufacturing counterweights, in particular to a method for manufacturing counterweights with a special drying step. Background technique [0002] Counterweights have long been used in people's lives and industrial production in various fields. For example, counterweights with different shapes and weights are used in drum washing machines used in daily life, lifting machinery such as elevators and cranes used in industrial production, and loading and unloading walking machinery such as forklifts and forklifts. [0003] At present, counterweights are mainly manufactured by casting process. This process needs to use a melting furnace to melt the scrap iron and steel as a raw material, and then pour the molten steel and molten iron into the mold, solidify, remove the mold, and then polish and maintain it to form the required counterweight. The advantage of manufacturing counterweights in this way is high den...
