Description

A heat treatment anti-deformation jig for spring leaf

technical field

The utility model belongs to the technical field of process equipment, and relates to a heat treatment anti-deformation fixture for a spring sheet.

Background technique

The spring leaf parts are made of beryllium bronze sheet through cutting and mechanical bending to form the shape and structure of the part, see Figure 1 and Figure 2. Finally, the material is strengthened through the heat treatment process to meet the elastic requirements, and all processing is completed. The leaf spring part is both a structural part and a functional part, carrying the function of providing elastic force. During the heat treatment process, the spring leaf parts will experience irregular deformation, such as: changes in the bending angle, shape distortion, etc., which seriously affect the quality of the parts.

Utility model content

The purpose of this utility model is to design a heat treatment anti-deformation fixture, which can prevent the deformation of the spring piece during the heat treatment process of the spring piece, ensure the bending angle and other elements of the part, and meet the quality requirements.

The technical scheme of the utility model: a heat treatment anti-deformation fixture, including a supporting plate 1, an upper splint 2, and a fastening screw 3, and the convex platform of the upper splint 2 is placed on the supporting plate 1 according to the direction of the concave groove of the supporting plate 1; The screw 3 connects and fastens the supporting plate 1 and the upper splint 2 through the threaded hole 5 .

Beneficial effects of the present invention: After using the heat treatment anti-deformation fixture, the parts are fixed according to the shape and bending angle of the parts, avoiding the deformation caused by the heat treatment process of the spring sheet, effectively ensuring the structural elements such as the bending angle, ensuring the elastic force requirements, and improving the quality of the parts .

detailed description

In order to better implement the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings, please refer to the accompanying drawings 1-10.

As shown in FIGS. 3-6 , a heat treatment anti-deformation fixture includes a supporting plate 1 , an upper clamping plate 2 , and fastening screws 3 . The supporting plate 1 is a steel product, and the groove of the supporting plate 1 is processed according to the size and angle of the outer surface of the part. After the parts are placed in the groove of the supporting plate 1, the outer surface of the part and the surface of the groove of the supporting plate 1 are completely bonded. The upper clamping plate 2 is a steel product and is used for positioning and clamping parts. The convex profile of the upper clamping plate 2 is processed according to the size and angle of the inner surface of the part, and the inner surface of the part and the convex profile surface of the upper clamping plate 2 are completely fitted. The convex platform of the upper splint 2 is placed on the supporting plate 1 according to the direction of the concave groove of the supporting plate 1; the fastening screw 3 connects the supporting plate 1 and the upper splint 2 through the threaded hole 5 . Pallet 1 is a steel product and is used to position and place parts. The groove of pallet 1 is exactly the same as the outer surface of the part. After the parts are placed in the groove of pallet 1, the outer surface of the part and the surface of the groove of pallet 1 are completely attached combine. There are four corners on the supporting plate 1 and are used to pass through fastening screw threaded holes 5 .

As shown in Figure 7 and Figure 8, the upper splint 2 is a steel product, which is used to position the clamping parts. Fits perfectly to contoured surfaces. Four light holes 6 for passing fastening screws are arranged on the four corners of the upper splint 2 .

After supporting plate 1, upper clamping plate 2 and leaf spring parts are assembled, fastening screw 3 will fasten supporting plate 1, upper clamping plate 2 that spring leaf parts are housed through threaded hole 5 and light hole 6. The leaf spring part is fixed in the fixture with the existing shape, and there will be no displacement between the spring leaf, the supporting plate, and the upper clamping plate.

Example:

For the leaf spring parts shown in Figure 1 and Figure 2, the specific implementation steps are as follows:

Step 1: Process the concave contour of the supporting plate 1 according to the outer surface size of the spring leaf part after cutting and bending.

The second step: process the convex profile of the upper splint 2 according to the size of the inner surface of the spring leaf part after cutting and bending.

Step 3: As shown in Figure 10, place the spring parts in the groove of the supporting plate 1, place the convex platform of the upper splint 2 on the supporting plate 1 according to the direction of the concave groove of the supporting plate 1, and fasten the supporting plate with the fastening screw 3. Four threaded holes 5 and light holes 6 on the plate 1 and the upper splint 2 are fastened. In this way, an anti-deformation clamp body that completely surrounds the spring leaf is formed.

Step 4: Carry out the heat treatment process with the anti-deformation clamp body including the spring piece together with the furnace to complete the heat treatment process.

Step 5: Disassemble the four fastening screws of the anti-deformation fixture, and take out the spring leaf parts.

In production practice, the actual size of the spring sheet is detected, and the spring sheet before and after heat treatment does not produce common deformation problems. The fixture achieves the heat treatment anti-deformation effect of the spring sheet.

As shown in Figure 9, a part is placed in the fixture. The fixture can also be designed to install multiple parts in one mold to improve production efficiency.
