[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0028] like Figure 1 As shown, a simple profiling device for manhole rings of steel box girders comprises a portal frame 1. The portal frame 1 can be made of steel plate waste in the production of steel box girders, or can be made of steel sections such as I-beams or channel steels in the production or construction of steel box girders. The portal frame 1 comprises a base 101, two side frames and a cross beam, wherein a die 4 is bolted to the base 101, and a pressing element 2 is arranged downward on the cross beam. The pressing element 2 is preferably a jack, and a punch 5 is bolted to the end of the pressing element 2.
[0029] The structure of the die 4 is as follows Figure 2 , Figure 3 and Figure 4 As shown, it includes a U-shaped plate and several concave templates 41 arranged side by side therein. The concave templates 41 are directly made of residual steel plates on site, for example, steel plates with a thickness of 12 mm. This embodiment takes three concave templates 41 as an example for explanation. The three concave templates 41 are arranged at equal intervals in the U-shaped plate with the opening facing upward, and the distance between the two outermost concave templates 41 corresponds to the width of the steel plate to be punched into the manhole ring. The bottom edge of the concave template 41 is welded to the bottom plate 43 of the U-shaped plate, and the two side edges of the concave template 41 are welded and fixed to the two side plates 42 of the U-shaped plate, thereby connecting and fixing the three concave templates 41 as one, improving the deformation resistance of the concave template and improving the strength of the die 4. A groove 411 is respectively provided at the top of the three concave templates 41. The groove 411 runs through the two end faces of the corresponding concave template. The bottom surface of the groove 411 is a semicircular arc surface corresponding to the manhole ring, and the two groove walls of the groove 411 are both vertical surfaces. The three male mold plates 41 have a total of three grooves 411 . The three grooves 411 are of the same size and shape and are coaxial and connected to form a stamping cavity.
[0030] The structure of the punch 5 is as follows Figure 5 , Figure 6As shown, it includes a mounting plate 53, a top plate 52 and three convex plates 51. The mounting plate 53 is used to connect with the end of the pressing element 2. The top plate 52 is connected to the bottom surface of the mounting plate 53. The three convex plates 51 are arranged side by side and at equal intervals on the bottom surface of the top plate 52. Each of the three convex plates 51 is directly opposite to a groove 411. The convex plate 51 also uses the residual steel plate on site, such as a steel plate with a thickness of 12 mm. The lower edge 511 of the convex plate 51 is a semicircular structure that matches the bottom of the groove 411, and the groove 411 can accommodate the convex plate 51. The two side edges 512 of the convex plate 51 are vertical sides, and the height of the side edges 512 itself is greater than the height of the side wall of the groove 411 itself, to prevent interference and ensure that the convex plate 511 punches the steel plate into the groove 411.
[0031] The convex mold plate 51 and the groove 411 of the concave mold 1 are opposite to form a stamping structure for stamping the steel plate placed on the top surface of the concave mold 4, such as Figure 7 When in use, the steel plate to be punched is placed on the top surface of the female die 4, the end of the pressing element 2 moves downward, driving the male die plate 51 to move downward, and the steel plate to be punched is punched into the groove 411 to form a semicircular arc panel structure, and the two arc panels are butted to form a manhole ring structure.
[0032] In this embodiment, a sliding groove is vertically provided on the inner side of a side frame of the portal frame 1, the end of the pressing element 2 is connected to the guide cross bar 3, and the distal end of the guide cross bar 3 is slidably connected to the sliding groove. This structure ensures the linearity of the downward movement of the punch 5, thereby ensuring that each punch plate 51 and the corresponding groove 411 are centered for stamping.
[0033] 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.
