Problems solved by technology

[0003] When processing refrigerator stamping parts, due to frequent stamping, there are often some small wastes in the processing mold, which is easy to affect the forming accuracy and quality of subsequent stamping parts, and due to the pressing down of the stamping material, the material may crack, Defects such as deformation and other defects will also affect the quality of stamping parts. For this reason, we have designed a processing method for refrigerator stamping parts to solve the above problems

Embodiment 1

[0020] A method for processing stamped parts of a refrigerator, comprising the following steps,

[0021] S1, blanking: inspect the raw material of the metal sheet, and cut the metal sheet according to the size of the stamping part of the refrigerator after passing the test to obtain the material to be stamped;

[0022] S2, one-time trimming: grinding the cutting edge of the material to be stamped in S1;

[0023] S3, Forming: Clean the mold cavity in the punching machine by blowing air, and anneal and soften the material to be stamped after trimming in S2. The softening and annealing temperature of the material to be stamped is 750°C, eliminating Internal stress, put the softened material to be stamped into the stamping machine, and after the positioning is fixed, it can be stamped into refrigerator parts;

[0024] S4, the second trimming: Trim and polish the punching and stamping parts of the stamping parts in S4, and after a full inspection, qualified finished refrigerator s...

Embodiment 2

[0026] A method for processing stamped parts of a refrigerator, comprising the following steps,

[0027] S1, blanking: inspect the raw material of the sheet metal, and cut the sheet metal according to the size of the stamping part of the refrigerator after passing the test to obtain the material to be stamped;

[0028] S2, one-time trimming: grinding the cutting edge of the material to be stamped in S1;

[0029] S3, Forming: Clean the mold cavity in the punching machine by blowing air, and anneal and soften the material to be stamped after trimming in S2. The softening and annealing temperature of the material to be stamped is 640°C, eliminating Internal stress, the softened material to be stamped is put into the stamping machine, and after the positioning is fixed, it can be stamped into refrigerator parts;

[0030] S4, the second trimming: Trim and polish the punching and stamping parts of the stamping parts in S4, and after a full inspection, qualified finished refrigerato...

Embodiment 3

[0032] A method for processing stamped parts of a refrigerator, comprising the following steps,

[0033] S1, blanking: inspect the raw material of the sheet metal, and cut the sheet metal according to the size of the stamping part of the refrigerator after passing the test to obtain the material to be stamped;

[0034] S2, one-time trimming: grinding the cutting edge of the material to be stamped in S1;

[0035] S3, Forming: Clean the mold cavity in the punching machine by blowing air, and anneal and soften the material to be punched after trimming in S2. The softening and annealing temperature of the material to be punched is 800°C, eliminating Internal stress, the softened material to be stamped is put into the stamping machine, and after the positioning is fixed, it can be stamped into refrigerator parts;

[0036] S4, the second trimming: Trim and polish the punching and stamping parts of the stamping parts in S4, and after a full inspection, qualified finished refrigerato...

Abstract

The invention relates to the technical field of stamping part machining, in particular to a refrigerator stamping part machining treatment method. The refrigerator stamping part machining treatment method comprises the following steps that firstly, discharging is conducted, metal plate raw materials are checked, after qualification is reached, a metal plate is cut according to the size of a refrigerator stamping part, and a to-be-stamped material is obtained; secondly, first-time edge trimming is conducted; thirdly, forming is conducted; and fourthly, second-time edge trimming is conducted. Inthe preparing process, the two-time edge trimming treatment is sequentially conducted on the stamping part; during first-time edge trimming treatment, the situation that fixing and stamping of the product are influenced due to burrs and other defects on the cut edge is avoided, and the precision of the subsequent machining technology is guaranteed; and during second-time edge trimming, the appearance and the product precision of the stamping part can be guaranteed. Before stamping, air blowing and dust removal are conducted on a stamping cavity and the to-be-stamped plate, the technology precision is further guaranteed, heating softening treatment is conducted before stamping, stress in the material can be eliminated, the phenomena of cracking and the like after stamping part forming areavoided, and the forming quality is reliable.

Description

technical field [0001] The invention relates to the technical field of stamping parts processing, in particular to a method for processing stamping parts of a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. [0003] When processing refrigerator stamping parts, due to frequent stamping, there are often some small wastes in the processing mold, which is easy to affect the forming accuracy and quality of subsequent stamping parts, and due to the pressing down of the stamping material, the material may crack, Defects such as deformation and other defects will also affect the quality of stamping parts. For this reason, we have designed a processing method for refrigerator s...
