[0022] Example 1

[0023] like Figure 1The flat steel cold working stretching limiter shown in the figure comprises a bottom fixing seat 100, a fixing ear plate 101, a set of supporting legs 102 and a flat steel blank 109.

[0024] A horizontal platform 103 is provided on the upper portion of a set of supporting legs 102.

[0025] A set of vertical plates 104 are symmetrically arranged on the horizontal platform 103.

[0026] The vertical plate 104 is symmetrically provided with vertical plate screw holes 105.

[0027] Horizontal screws 106 are installed on the vertical plates 104 through the vertical plate screw holes 105.

[0028] On the horizontal screw 106, horizontal screw nuts 107 are respectively provided on both sides of the vertical plate 104.

[0029] A vertical U-shaped guide portion 108 is symmetrically provided on the opposite end surface of the horizontal screw 106;

[0030] The flat steel blank 109 passes horizontally through a cavity formed by a set of vertical U-shaped guides 108 , and the relative spacing between the set of vertical U-shaped guides 108 is achieved by rotating the horizontal screws 106 respectively.

[0031] The working principle is: first, according to the width size of the flat steel billet 109, the horizontal screw 106 is rotated to the appropriate relative spacing position (the flat steel billet 109 can pass through), and then the horizontal screw nut 107 is rotated to lock the horizontal screw 106, and finally grease is applied to the surface of the flat steel billet 109 to ensure that the flat steel billet 109 passes smoothly through the cavity formed by a set of vertical U-shaped guide parts 108, so that the guidance and limitation of flat steel billets 109 of different width sizes can be met.

[0032] Example 2

[0033] Based on the first embodiment, Figure 2 and Figure 3 The illustrated flat steel cold working stretching limiter device further includes vertical U-shaped guide screw holes 110 respectively provided in one end surface of the vertical U-shaped guide portion 108, vertical screws 111 respectively mounted on the vertical U-shaped guide portion 108 through the vertical U-shaped guide screw holes 110, vertical screw nuts 113 respectively provided on the vertical screws 111 and located on both sides of the vertical U-shaped guide portion 108, multi-angle adjustment blocks 112 respectively provided on one end surface of the vertical screws 111, and position limiting guides 114 respectively provided on the other end surface of the vertical screws 111 and located in the vertical U-shaped guide portion 108;

[0034] The limiting guide portion 114 is in sliding contact with the surface of the flat steel blank 109 .

[0035] The working principle is: according to the thickness of the flat steel billet 109, the vertical screw 111 is rotated to the appropriate position (the flat steel billet 109 can pass through) through the multi-angle adjustment block 112, and then the vertical screw nut 113 is rotated to lock and fix the vertical screw 111. In this way, the guiding and limiting requirements of flat steel billets 109 of different thicknesses can be met.

[0036] Example 3

[0037] On the basis of Example 1 or Example 2, Figure 4 and Figure 5 The illustrated flat steel cold working stretching limiter device further includes a chute 115 disposed within one surface of the horizontal plate 103 and located between a set of vertical plates 104, and supporting sliders 116 disposed on the outer wall of the other end surface of the vertical U-shaped guide portion 108 and located within the chute 115.

[0038] The slide groove 115 (filled with lubricating grease) is configured as a straight-line structure, and the supporting slider 116 is configured as a quadrilateral structure.

[0039] The working principle is: when the relative position of the vertical U-shaped guide part 108 is adjusted horizontally relative or oppositely, the slide groove 115 slides on the support slider 116 to achieve convenient adjustment support; in addition, after the adjustment is completed and fixed, the support slider 116 performs vertical limiting support on the vertical U-shaped guide part 108 to improve its load-bearing capacity and achieve safe and stable limiting guidance of the flat steel billet 109.

[0040] In addition, the sliding contact surface between the limiting guide portion 114 and the flat steel blank 109 is preferably set to a circular structure or an arc structure; when the arc structure is adopted, the sliding contact area between the limiting guide portion 114 and the flat steel blank 109 is reduced, that is, the vertical limitation is ensured, and the friction resistance is reduced without affecting the smooth sliding of the flat steel blank 109.

[0041] The flat steel cold working stretching limit device of this structure has a vertical design structure, occupies a small area, and can be conveniently assembled between the tail end of the feeding equipment and the front end of the stretching equipment / finishing equipment.
