Description

Technical Field

[0001] The utility model relates to a forming die with a sunken stainless steel part. Background Art

[0002] At present, a large number of stainless steel parts with depressions are used in aircraft structures. When such parts are formed using ordinary molds, wrinkles are easily formed around the depression area after the contact between the punch and the die. The subsequent shaping by fitters is troublesome and time-consuming, which increases the cost of later processing of the parts. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a forming die with a sunken stainless steel part.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a forming die with a sunken stainless steel part, comprising:

[0005] Die seat;

[0006] The invention is characterized in that: a concave mold plate is fixedly installed on the top of the concave mold seat, guide column sleeves are provided at the four corner edges of the top of the concave mold plate, a concave mold is provided on the top end surface of the concave mold plate, a first rib groove and a second rib groove are respectively provided on the front and rear sides of the concave mold, a first pressure plate is provided on the top cover of the concave mold plate, a second pressure plate is provided on the top cover of the first pressure plate, a punch seat is provided above the second pressure plate, a punch mold plate is fixedly installed below the punch seat, guide columns matching with the guide column sleeves are provided at the four corner edges of the bottom of the punch mold plate, and a punch matching with the concave mold is provided on the bottom end surface of the punch mold plate.

[0007] In the above structure, a first rib and a second rib are provided on the bottom end surface of the first edge pressing plate, respectively matching with the first rib groove and the second rib groove.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the molding die structure design of the stainless steel parts with depressions of the utility model is reasonable, and the stretching molding of the parts is realized by the cooperation between the punch and the die. At the same time, the part profile is tightened by the ribs on the first edge plate and the rib grooves on the die plate, and then the punch is used for molding, so that there are no wrinkles in the depressed area of ​​the part, which reduces labor costs and improves efficiency.

[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-7 As shown, a forming die for a stainless steel part with a sunken shape comprises:

[0020] Die seat 1;

[0021] The invention is characterized in that: a die plate 2 is fixedly installed on the top of the die seat 1, guide column sleeves 3 are provided at the four corner edges of the top of the die plate 2, a die 4 is provided on the top surface of the die plate 2, a first rib groove 5 and a second rib groove 6 are respectively provided on the front and rear sides of the die 4, a first pressure plate 7 is provided on the top cover of the die plate 2, a second pressure plate 8 is provided on the top cover of the first pressure plate 7, a punch seat 9 is provided above the second pressure plate 8, a punch plate 10 is fixedly installed below the punch seat 9, guide columns 11 matching with the guide column sleeves 3 are provided at the four corner edges of the bottom of the punch plate 10, and a punch 12 matching with the die 4 is provided on the bottom end surface of the punch plate 10.

[0022] In the above structure, the first rib 13 and the second rib 14 are respectively matched with the first rib groove 5 and the second rib groove 6 on the bottom end surface of the first edge pressing plate 7 .

[0023] When the forming mold of the sunken stainless steel part of the utility model is in operation, the concave die seat is installed on the lower platform of the hydraulic press machine, the punch seat is installed on the upper platform of the hydraulic press machine, the part is placed on the concave template, the first edge clamping plate and the second edge clamping plate are placed on the part, the punch seat and the upper platform of the hydraulic press move downward together, the first rib and the second rib on the first edge clamping plate cooperate with the first rib groove and the second rib groove on the concave template, the part is tightened, and then the second edge clamping plate is taken out and the mold is closed again. At this time, the first edge clamping plate presses the part tightly, and the punch slowly moves downward to produce a deep drawing effect to form the part.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention.
