Abstract
The invention discloses a production method of sheet metal parts. The production method includes the steps: A, pre-punching a sheet metal part to make a round hole; B, placing the sheet metal part between an upper die and a lower die for embossing; and C, broaching the pre-punched round hole until the round hole of the sheet metal part meets the required diameter after embossing. The diameter of the pre-punched round hole is smaller than the required diameter of the round hole of the sheet metal part. The production method has the advantages that embossing is simple, die production is simple and fast, and size precision of finished products is guaranteed by broaching after parts positioning and upper die guiding through the pre-punched round hole during embossing.
Description
Technical field
The present invention relates to mechanical manufacturing field, relate in particular to a kind of manufacture method of sheet metal part.
Background technology
In the production of sheet metal part, we usually can run into a kind of raising structure (as shown in Figures 1 and 2), and the central authorities of described raising structure are provided with circular port, make this kind raising structure and usually adopt a kind of raising low-cost die (as shown in Figure 3).In daily production process, people are general, and size is made with the hole according to the rules first, and then put into the mould raising, yet, the defective that it is found that this kind manufacture method is: described circular hole is sometimes because raising size and depth relation has widening in various degree, higher to the circular hole dimension precision requirement such as part itself, will affect the assembling of this part.
Therefore, be necessary to provide a kind of manufacture method of the sheet metal part that solves the problems of the technologies described above.
Summary of the invention
Technical problem to be solved by this invention is: a kind of manufacture method that improves the sheet metal part of Product Precision is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of manufacture method of sheet metal part, the steps include: A) pre-punching one circular hole on sheet metal part at first, this diameter dimension that rushes in advance circular hole is less than the desired diameter dimension of the circular hole of sheet metal part, B) then sheet metal part is positioned over and carries out raising between patrix and the counterdie, C) raising is complete carries out reaming to the desired diameter dimension of the circular hole of sheet metal part afterwards to rushing in advance circular hole.
The invention has the beneficial effects as follows: adopt above-mentioned manufacture method, the raising low-cost die is made simple and fast, comes locating element and correcting patrix with rushing in advance circular hole in the raising, and reaming can guarantee the dimensional accuracy of final products again.
Description of drawings
Fig. 1 is the front view of sheet metal part.
Fig. 2 is the sectional view of sheet metal part.
Fig. 3 is the structural representation of raising low-cost die.
Among Fig. 1 to Fig. 3: 100, sheet metal part, 1, circular hole, 2, patrix, 3, counterdie, 4, pin.
The specific embodiment
See also Fig. 1 to Fig. 3, a kind of manufacture method of sheet metal part 100, the steps include: A) pre-punching one circular hole on sheet metal part 100 at first, this rushes the diameter dimension of circular hole in advance less than the circular hole 1 desired diameter dimension of sheet metal part 100, B) then sheet metal part 100 is positioned between patrix 2 and the counterdie 3 and carries out raising, C) raising is complete carries out reaming to the circular hole 1 desired diameter dimension of sheet metal part afterwards to rushing in advance circular hole.Locate by pin 4 between described sheet metal part 100 and patrix 2, the counterdie 3.
The advantage of this kind manufacture method is: the raising low-cost die is made simple and fast, comes locating element and correcting patrix with rushing in advance circular hole in the raising, and reaming can guarantee the dimensional accuracy of final products again.
Claims (2)
1. the manufacture method of a sheet metal part, the steps include: A) pre-punching one circular hole on sheet metal part at first, this diameter dimension that rushes in advance circular hole is less than the desired diameter dimension of the circular hole of sheet metal part, B) then sheet metal part is positioned over and carries out raising between patrix and the counterdie, C) raising is complete carries out reaming to the desired diameter dimension of the circular hole of sheet metal part afterwards to rushing in advance circular hole.
2. the manufacture method of a kind of sheet metal part as claimed in claim 1 is characterized in that: between described sheet metal part and the upper die and lower die by finger setting.
