Description

Technical Field

[0001] The utility model belongs to the technical field of high-strength steel plate profile processing equipment for automobiles, in particular to a device for performing shaping treatment on four points before cutting of a cold-formed ultra-high-strength plate. Background Art

[0002] Figure 1 It is a continuous cold-formed ultra-high-strength plate with a roughly "J"-shaped cross section. It is made of ultra-high-strength martensitic steel with a yield strength of 1500Mpa. It is formed by cold forming roller pressing process and needs to be cut at the two dotted lines 13 in the figure. In order to avoid scratches on personnel during transportation of the cut product, it is necessary to first cut a notch 12 on both sides of the flank 11 at the cutting point, so that the two corners of the end of the product after cutting can directly form chamfers 121. Since the material used in this product is very hard, it is easy to cause rebound deformation on both sides of each notch 13, so it is necessary to design a shaping device to eliminate the deformation problem before cutting.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0025] In the description of the embodiments of the present invention, it should be noted that the indicated orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the application product is usually placed when in use, or is the orientation or position relationship commonly understood by technical personnel in this field. It is only for the convenience of describing the present invention or simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] The term "plurality" in the present invention refers to more than two (including two). The terms "first", "second" and the like are only used to distinguish descriptions and should not be understood as indicating or implying relative importance.

[0027] Unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] The utility model includes a base 21, and an intermediate platform 22, a lifting platform 23 and a top platform 24 are sequentially arranged above the base 21; the base 21 fixes and supports the top platform 24 through a support column 27, the cylinder body of the hydraulic cylinder 5 is fixed on the top platform 24, the piston rod is coaxially connected to the pressing rod 6 through a connecting piece, the pressing rod 6 passes through the top platform 24 and the bottom end is fixedly connected to the lifting platform 23, and the lifting platform 23 is driven by the hydraulic cylinder 5 to descend and lift.

[0030] The two sides of the middle platform 22 are supported and fixed to the base 21 by support blocks 26 respectively. The lower mold insert 3 is fixed on the base 21 and is located between the two support blocks 26 and directly below the middle platform 22. The lower mold insert 3 is used to support the middle part 10 of the product.

[0031] The utility model is equipped with four upper mold inserts 4 and four pads 4, which correspond to four points that need to be shaped respectively. Each upper mold insert 4 vertically passes through the corresponding guide through hole opened on the middle platform 22 respectively. The top of each upper mold insert 4 is fixedly connected to the lower surface of a pad 4. The bottom end of each upper mold insert 4 is fixedly provided with a shaping head for pressing against the corresponding point on the product flank 11 for shaping. The upper surface of each pad 4 is abutted against the bottom end of a stroke adjustment bolt 44. The four stroke adjustment bolts 44 vertically pass through the lifting platform 23 respectively and are screwed with the corresponding threaded holes opened on the lifting platform 23. The extension amount of the stroke adjustment bolt 44 under the lower surface of the lifting platform 23 can be adjusted by rotating, and the extension amount of the stroke adjustment bolt 44 is locked by the locking nut 45. The extension amount of the stroke adjustment bolt 44 directly determines the downward stroke of the corresponding upper mold insert 4 and the shaping amount of the corresponding point by its shaping head. Therefore, the shaping amount of the four points in the utility model can be adjusted separately through the above structure.

[0032] Each upper die insert 4 is also provided with a return spring 42 on both sides. The upper and lower ends of the return spring 42 are respectively in contact with the backing plate 4 and the middle platform 22 , and the return spring 42 provides lifting and returning of the upper die insert 4 .

[0033] Since the lower pressure rod 6 and the lifting platform 23 to which it is fixed may rotate around the axis, the stroke adjustment bolt 44 may cause the corresponding pad 41 to deviate or even lose contact. Therefore, the lifting platform 23 is also fixed with two anti-rotation pins 43, each of which passes through and is clamped between a pair of pads 4 to prevent the lifting platform 23 from rotating.

[0034] When the upper die insert 4 is pressed downward, it will be subjected to upward and outward reaction forces from the product side wings 11. The upward reaction force is suppressed by the driving force provided by the hydraulic cylinder 5, while the outward reaction force is slidably abutted against the sides of the two upper die inserts 4 on the same side through the side block gasket 25 fixed on the inner side of the support block 26, thereby serving as an auxiliary guide for the upper die insert 4 and overcoming the outward deviation reaction force it is subjected to, while reducing wear and facilitating replacement.

[0035] like Figure 3 As shown, the lifting platform 23 is fixedly connected with a sensing sheet 72, and the intermediate platform 22 is installed with a displacement sensor 71 via a connecting frame 711, which is used to monitor whether the lifting stroke of the lifting platform is in place.

[0036] like Figure 2 As shown, handles 8 are also fixedly provided on both sides of the top platform 24 to facilitate the transportation of the entire utility model.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
