Stable heat treatment clamp for stainless steel parts

Abstract

The utility model discloses a stable heat treatment clamp for a stainless steel part. The die is characterized in that a die groove is formed in the top of the lower die, an upper die is arranged in the die groove, three positioning blocks are arranged on the left side wall and the right side wall of the lower die respectively, wedge block holes are formed in the side walls of the positioning blocks, and the wedge block holes of the positioning blocks on the left side and the right side are aligned and then fixed by inserting wedge blocks. The stable heat treatment clamp for the stainless steel part is reasonable in structural design, the bent edge part with allowance removed through cutting is positioned and placed between the lower die and the upper die and fixed through the wedge block, the clamping force of the wedge block is large, the effects of relieving stress and correcting the part can be effectively achieved in the heat treatment process, and the machining efficiency is improved. Residual stress generated after the cutting allowance removing process is eliminated, the curvature of the bent edge of the repaired part meets the use requirement of a drawing, and meanwhile the heat treatment clamp is simple and convenient in structure and easy to operate.

Description

Technical Field

[0001] The utility model relates to a stable heat treatment fixture for stainless steel parts. Background Art

[0002] With the continuous development and progress of science and technology, 17-7PH stainless steel is increasingly used in aircraft. After the 17-7PH stainless steel parts are formed and the parts are removed, the curvature of the two curved edges changes due to stress after the cutting process, which cannot meet the requirements of the drawings. Therefore, a stable heat treatment fixture for stainless steel parts is urgently needed. Utility Model Content

[0007] In the above structure, hanging rings are provided on both the left and right side walls of the lower mold.

[0008] In the above structure, a plurality of positioning pins are provided on the side walls of the mold groove.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the stable heat treatment fixture structure of the stainless steel parts of the utility model is reasonably designed, the bent edge parts with cut excess are positioned between the lower die and the upper die, and fixed by a wedge block, the wedge block has a large clamping force, and can effectively eliminate stress and correct the shape of the parts during the heat treatment process, eliminate the residual stress after the cutting excess process, and repair the bent edge curvature of the parts to meet the requirements of the drawing. At the same time, the heat treatment fixture structure is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of a stable heat treatment fixture for stainless steel parts according to an embodiment of the utility model;

[0011] Figure 2 The utility model is a schematic diagram of the exploded structure of a stable heat treatment fixture for stainless steel parts described in an embodiment of the utility model.

[0012] In the figure:

[0014] 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.

[0015] like Figure 1-2 As shown, a stable heat treatment fixture for stainless steel parts includes:

[0016] Lower mold 1;

[0017] The invention is characterized in that: a die groove 2 is provided on the top of the lower die 1, an upper die 3 is provided inside the die groove 2, three positioning blocks 4 are respectively provided on the left and right side walls of the lower die 1, wedge holes 5 are provided on the side walls of the positioning blocks 4, and the wedge holes 5 of the positioning blocks on the left and right sides are aligned and fixed by inserting wedges 6.

[0018] In the above structure, hanging rings 7 are provided on both the left and right side walls of the lower mold 1 .

[0019] In the above structure, a plurality of positioning pins 8 are provided on the side wall of the mold cavity 2 .

[0020] The utility model discloses a stable heat treatment fixture structure design of stainless steel parts, the part with bent edge after cutting and removing the excess is positioned between the lower die and the upper die, and fixed by a wedge block, the wedge block has a large clamping force, and can effectively eliminate stress and correct the shape of the part during the heat treatment process, eliminate the residual stress after the process of cutting and removing the excess, and repair the curvature of the bent edge of the part to meet the requirements of the drawing. At the same time, the heat treatment fixture structure is simple and easy to operate.

[0021] 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.
