Combined balance case and manufacturing method thereof

Abstract

The invention discloses a combined balance case and a manufacturing method thereof. The manufacturing method includes the following steps of (1), cutting an inner wall plate and an outer wall from plate materials according to unfold sizes of an inner wall board and an outer wall board, and cutting two same ring-shaped bottom plates from the plate materials according to the unfold size of a bottom board; (2), subjecting the outer wall plate and the inner wall plate to hole opening, and stamping the inner edge and the outer edge of the bottom plate so that the inner edge and the outer edge of the bottom board to form bent edges which are in circular arc transition; (3), subjecting the inner wall plate and the outer wall plate which are processed in step (2) to bending processing by using a bending machine to form the inner wall plate and the outer wall plate; and then welding the two bottom plates which are processed in step (2) to the upper edge and the lower edge of the inner wall board and the outer wall board to form the combined balance case. The manufacturing method has the advantages of being low in production equipment, simple in production process, and convenient to produce in large scales, and accuracy is easy to guarantee.

Description

technical field [0001] The invention relates to components of a combination scale and a manufacturing method thereof, in particular to a combination weighing machine case and a manufacturing method thereof. Background technique [0002] Combination scale refers to a weighing device composed of multiple weighing units with independent feeding and discharging structures, which has been widely used in the food packaging industry. Among them, the combination scale chassis is an important part of the combination scale, which is located under the combination scale and plays a supporting role, and its internal space is used to arrange various circuit components of the combination scale. [0003] The invention patent with the authorized notification number CN102155977B discloses a "casing for combination scales and a method for manufacturing the chassis for combination scales". , the inner wall panels and the corner panels; then the main chassis panels are stamped to form the main ...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution has the advantages of relatively simple process, good stability, and excellent sealing performance, but there are still the following disadvantages: when stamping the main chassis plate into the main chassis, due to the large size of the main chassis in the height direction (i.e. The height of the side panel), so not only the stamping equipment is required to have a larger stroke, but also a greater stamping force is required, which increases the volume of the stamping die and stamping equipment, complicates the structure, and also increases the energy consumption of the stamping equipment, thereby improving cost of equipment
