Embodiment Construction

[0035] The present invention will be described in further detail below according to the drawings and embodiments.

[0036] The present invention includes a molding system, a feeding manipulator, and an automatic centering system.

[0037] refer to figure 1 , figure 2 , the one-time forming system of the elastic strip forming machine, including an upper mold 17, a lower mold 13, an upper positioning column 15, a lower positioning column 16, a middle push arm 12, two side push arms 11, and two limb push arms 14;

[0038] Wherein, the surface of the upper mold 17 is facing the surface of the lower mold 13;

[0039] Two upper positioning columns 15 and two lower positioning columns 16 are provided. The above two upper positioning columns 15 are symmetrically fixed above the surface of the lower mold 13, and the above-mentioned lower positioning columns 16 are symmetrically fixed below the surface of the lower mold 13. The distance between the positioning columns 15 is greater...

Abstract

The invention discloses an elastic strip forming machine which comprises a one-time forming system, a feeding manipulator and an automatic centering system. The one-time forming system comprises an upper die, a lower die, an upper positioning column, a lower positioning column, a middle pushing arm, two lateral pushing arms and two limb pushing arms. The feeding manipulator comprises a grabbing mechanism, a telescoping mechanism, a rotating mechanism and a transverse moving mechanism. The automatic centering system comprises an upper connecting rod, a lower connecting rod, a rotating mechanism, a left material blocking plate, a right material blocking plate and a drive mechanism. The elastic strip forming machine has the advantages of achieving one-time forming production of elastic strips and improving the production efficiency of the elastic strips and the pass percent of products.

Description

technical field [0001] The invention relates to a spring strip forming machine. Background technique [0002] W-type elastic strip is an important part of the railway fastener system, such as A, B and II-type elastic strips, and its shape is as follows: Figure 1 As shown, they serve to secure the rail in the fastening system while providing rail elasticity. The W1 and W2 spring clips used on the high-speed railway passenger dedicated line are all large-sized W-shaped clips. One of the most critical and complex is the elastic strip forming process. Due to the large size and high precision requirements of the W-shaped spring bars for passenger dedicated lines, they cannot be formed at one time. The method is manual feeding. Its production process has the following disadvantages: the molding process is backward. There are many processes, affected by human factors, mold adjustments, and multiple molding positioning benchmarks, the size of the product fluctuates greatly, the...
