Problems solved by technology

[0003] This type of product adopts a thermoforming process. After the W elastic strip is formed, the product needs to be pre-pressed to reduce the residual deformation of the product. The current pre-pressing equipment in the factory is a manual hydraulic press, which is inconvenient to operate and low in efficiency. It is difficult to ensure that the stroke meets the requirements, resulting in insufficient preload, resulting in the product residual deformation test results not meeting the requirements

Embodiment Construction

[0020] The present invention will be described in further detail below according to the drawings and embodiments.

[0021] refer to Figure 1-Figure 3 According to the present invention, an automatic preloading device for W-shaped elastic strips includes a plurality of preloading mechanisms 1 and a delivery channel 2, and multiple preloading mechanisms 1 are installed side by side on the side of the delivery channel 2. The conveying channel 2 is used to convey the W-shaped elastic strip 100 and can convey the W-shaped elastic strip 100 to each of the pre-pressing mechanisms 1, and the pre-pressing mechanism 1 includes a frame 11, a hydraulic cylinder 12, and a pressure head 13. The hydraulic cylinder 12 is fixed on the top of the frame 11 , and the pressure head 13 is assembled on the bottom of the hydraulic cylinder 12 and can be pressed against the W-shaped elastic bar on the surface of the frame 11 .

[0022] Further, the conveying channel 2 is provided with a pushing cyli...

Abstract

The invention discloses an automatic prepressing device for W type elastic strips. The device comprises multiple prepressing mechanisms and a conveying channel; the multiple prepressing mechanisms aremounted at the side part of the conveying channel side by side; the conveying channel is used for conveying the W type elastic strips to each prepressing mechanism; the prepressing mechanisms comprise frames, hydraulic cylinders and pressing heads; the hydraulic cylinders are fixed at the tops of the frames; and the pressing heads are assembled at the bottoms of the hydraulic cylinders, and can be pressed to the W type elastic strips on the surfaces of the frames. The device has the beneficial effects of reduction of labors and guarantee of each product to reach a fixed prepressing quantity to guarantee the product quality requirements.

Description

technical field [0001] The invention relates to an automatic preloading device, in particular to an automatic preloading device for a W-shaped spring bar. Background technique [0002] W-type elastic strip is a common type of fastener used in railway fastener system. W1, W2, etc. are used on high-speed railways. [0003] This type of product adopts a thermoforming process. After the W elastic strip is formed, the product needs to be pre-pressed to reduce the residual deformation of the product. The current pre-pressing equipment in the factory is a manual hydraulic press, which is inconvenient to operate and low in efficiency. It is difficult to ensure that the stroke meets the requirements, resulting in insufficient preload, resulting in the product residual deformation test results not meeting the requirements. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automatic preloading device for W-shaped elastic ...
