Problems solved by technology

[0004] There are following shortcoming in above-mentioned processing procedure: (1) as figure 1 As shown, the chassis for the combination scale is formed by directly splicing plane material plates together, and the edge 1 formed by the splicing of each plane material plate has poor transition, which makes the welding stress on the edge of the chassis for the combination scale large and easy to deform; ( 2) The size deviation caused by the plate cutting process will cause inconsistencies in the size and shape of the chassis of the same model. In severe cases, the connection between the plates will not be compact, which will affect the airtightness of the chassis; (3) Cut out several pieces The flat plates are joined together by welding. The welding is difficult, the stability of the finished product is poor, the required production cycle is long, and the production efficiency is affected. It is not suitable for mass production.

Embodiment 1

[0045] The manufacturing method of the cabinet for the combination scale adopts the mold stamping forming process to punch out the main cabinet, and then joins the sealing structure of the cabinet for the combination scale by supplementing the lower bottom plate, the inner wall board and the stamped corner plate into an arc shape, so as to complete the cabinet for the combination scale The manufacture specifically includes the following steps:

[0046] (1) According to the expansion size of the designed chassis, accurately cut out the contour line of the required material plate from the stainless steel plate at a ratio of 1:1, mainly cutting out the main chassis plate, lower bottom plate, inner wall plate and corner plate. .

[0047] (2) Hole flanging:

[0048](2-1) In this embodiment, a punching die is used to open holes, and an installation window 4, an installation hole 6, and an installation hole 7 are formed on the main chassis plate that has obtained an accurate contour...

Embodiment 2

[0060] This embodiment has the same characteristics as Embodiment 1 except for the following features: in the step (3), the pressure holding time is 2 seconds.

[0061] In the step (2), the installation window 4, the installation hole 6, and the installation hole 7 are opened at the corresponding position of the main chassis plate by laser technology, and the installation hole 11 is opened at the corresponding position of the inner wall plate. Hole 9: use a tapping machine to drill threaded holes 5 and 16 at the corresponding positions of the main body chassis plate and the inner wall plate.

Abstract

The invention provides a method for manufacturing a case for a combined scale, comprising the following steps: (1) cutting a main case plate profile, a bottom plate, inner wall plate profiles and all corner splicing plate profiles; (2) arranging installation windows, installation holes and thread holes on the main case plate profile and the inner wall plate profiles, and flanging the installationwindows; (3) pressing the main case plate profile integrally, maintaining the pressure, and then taking out; pressing the inner wall plate profiles to obtain inner wall plates, and pressing the corner splicing plate profiles to obtain corner splicing plates; and (4) connecting the formed main case, the inner wall plates, the corner splicing plates and the bottom plate together to obtain the case for the combined scale. The invention further provides the case for the combined scale, which is manufactured by adopting the method. The case for the combined scale comprises the main case, the innerwall plates, the bottom plate and the corner splicing plates and further comprises a top panel, inner panels and outer panels, which are integrally formed. The invention has the advantages of being simple in process and convenient for large-scale production.

Description

technical field [0001] The invention relates to the technical field of cabinet manufacturing, in particular to a cabinet for a combination scale and a manufacturing method for the cabinet for the combination scale. 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 chassis for the combination scale is an important part of the combination scale and is located below the combination scale. In order to facilitate line layout and post-management, various circuit components of the combination scale are centrally accommodated inside the combination scale chassis, so the airtightness and stability requirements of the combination balance chassis are relatively high. [0003] At present, in the manufacturing process of combined scales at home and abroad, the chassis of combined scales is generally ...
