Embodiment Construction

[0023] As attached in the manual Figure 1 to Figure 2 A heart-shaped ring for a pre-twisted tension clamp shown in the figure includes a heart-shaped ring body 1, the upper part of the heart-shaped ring body 1 is provided with a hardware bolt hole 2, and the middle part of the heart-shaped ring body 1 is provided with a through hole 3. Fitting bolts 4 are inserted in the fitting bolt holes 2 .

[0024] The hole diameter of the hardware bolt hole is 28mm.

[0025] The radius of the arc at the lower part of the heart-shaped ring body is 25.4mm.

[0026] as attached image 3 As shown, a manufacturing process of a pre-twisted tension clamp with a heart-shaped ring includes the following steps:

[0027] Step 1: Blanking the raw material through the blanking mold;

[0028] Step 2: The blanked module is punched through the punching die;

[0029] Step 3: After punching, the module is pressed;

[0030] Step 4: The molded module is formed by the molding module, and the blank is h...

Abstract

The invention relates to a heart-shaped ring for a pre-twisted strain clamp. The heart-shaped ring comprises a heart-shaped ring body, wherein a hardware fitting bolt hole is formed in the upper portion of the heart-shaped ring body in a penetrating mode, a through hole is formed in the middle of the heart-shaped ring body in a penetrating mode, and a hardware fitting bolt is inserted into the hardware fitting bolt hole. The invention further provides a manufacturing process of the heart-shaped ring for the pre-twisted strain clamp. The manufacturing process comprises the steps of blanking, punching, compression, forming, shaping, hot galvanizing and assembling. The heart-shaped ring is formed by a steel plate, the quality is stable, and casting defects are small.

Description

technical field [0001] The invention specifically relates to a heart-shaped ring for a pre-twisted tension clamp and a manufacturing process thereof. Background technique [0002] Heart-shaped rings are generally used in conjunction with pre-twisted strain clamps. Traditional heart-shaped rings are castings made of malleable cast iron, which have casting defects and unstable quality. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a heart-shaped ring for a pre-twisted tension clamp and its manufacturing process. The heart-shaped ring is formed by a steel plate and has stable quality. [0004] The present invention is achieved through the following technical solutions: a heart-shaped ring for pre-twisted tension wire clamps, including a heart-shaped ring body, the upper part of the heart-shaped ring body is provided with hardware bolt holes, and the middle part of the heart-shaped ring body A through hole is fo...
