Description

Technical Field

[0001] The utility model relates to the technical field of angle steel opening and closing angle moulds, in particular to a large-size angle steel opening and closing angle mould. Background Art

[0002] Angle steel is a material widely used in construction and engineering projects. It is characterized by long strips of steel with two sides perpendicular to each other and forming an angle. It is commonly found in structures such as beams, bridges, and transmission towers. The angle steel opening and closing angle mold is a mold used to change the 90° angle of the cross section of the angle steel, aiming to expand or reduce its angle to facilitate the installation of the tower and increase its overall stiffness and the deformation resistance of the connecting parts.

[0003] In the prior art, a patent document with application number CN201620095813.8 reviewed and published by the State Intellectual Property Office of China discloses a utility model patent named angle steel opening and closing angle mold, which includes an upper mold assembly and a lower mold assembly, wherein the upper mold assembly includes a top plate and an upper mold positioning block group, the bottom of the top plate is movably connected to the upper mold positioning block group, the upper mold positioning block group is a plurality of upper mold positioning blocks with inverted triangle structures and right angles, an oil injection device is provided at the bottom of the top plate near the upper mold positioning block group, the lower mold assembly matches the upper mold assembly, and the lower mold assembly includes a bottom plate and a lower mold positioning block group, The bottom plate is provided with limit blocks, which are respectively arranged on both sides of the lower die positioning block group and are detachably connected to the bottom plate. The lower die positioning block group includes a plurality of lower die positioning blocks with triangular structures and right angles. The number of the lower die positioning blocks is one more than the number of the upper die positioning blocks. The lower die positioning block is staggered with the upper die positioning block. The lower die positioning block is provided with a movable angle block, and the movable angle block is detachably connected to the lower die positioning block. The angle steel opening and closing angle mold can produce multiple groups of angle steels at a time, so it can be suitable for large-scale production of angle steels, and angle steels with different angles can be obtained by setting different movable angle blocks.

[0004] However, when the angle steel opening and closing angle mold in the prior art is used for large-size angle steel opening and closing angle molds, its movable angle block lacks a limiting mechanism, which is easily compressed during the production process of the angle steel, causing the movable angle block to move around, resulting in a decrease in the production accuracy of the angle steel.

It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a large-size angle steel opening and closing angle mold, comprising: a bottom plate 1, a lower mold positioning block group 2 is fixed on the top of the bottom plate 1, a movable angle block 3 is arranged on the surface of the lower mold positioning block group 2, a side plate 4 is fixed on the side of the bottom plate 1, a movable angle block plug-in hole 5 is opened on the surface of the side plate 4, both ends of the movable angle block 3 extend into the movable angle block plug-in hole 5, a pressure rod 7 is movably connected on the surface of the side plate 4, the pressure rod 7 is against the end surface of the movable angle block 3 away from the lower mold positioning block group 2, and two groups of side plates 4 are arranged, and the two groups of side plates 4 are symmetrically distributed about the bottom plate 1.

[0021] During actual use, after placing the movable angle block 3 on the lower die positioning block group 2 arranged at the top of the base plate 1, the two ends of the movable angle block 3 are extended into the movable angle block plug-in holes 5 opened on the surface of the side plate 4, and then the posture of the pressure rod 7 is adjusted by adjusting the position of the slider 8 on the guide rail 6, so that the pressure rod 7 is pressed tightly on the surface of the end of the movable angle block 3 away from the lower die positioning block group 2, and then the slider 8 is limited, and the movable angle block 3 is clamped in the middle by the pressure rod 7 and the lower die positioning block group 2, thereby limiting the movable angle block 3 to prevent the movable angle block 3 from running around and causing a decrease in production accuracy. Embodiment 2

[0022] On the basis of Example 1, in order to adjust the posture of the pressure rod 7 by adjusting the slider 8, two sets of guide rails 6 are fixed on the surface of the side panel 4, and the two sets of guide rails 6 are symmetrically distributed up and down about the movable angle block plug-in hole 5. A number of sets of sliders 8 are slidably connected on the surfaces of the two sets of guide rails 6, and the sliders 8 are in a "C"-shaped plate structure. An axial hole 9 is opened on the surface of the pressure rod 7, and a connecting shaft 10 is fixed on the surface of the slider 8, and the connecting shaft 10 is rotatably connected in the axial hole 9.

[0023] Two groups of axial holes 9 are opened on the surface of a group of pressure rods 7, and connecting shafts 10 are connected to the two groups of axial holes 9. The two groups of connecting shafts 10 are fixed on two groups of sliders 8, and the two groups of sliders 8 are respectively slidably connected on the surfaces of the upper and lower groups of guide rails 6. The posture of the pressure rod 7 can be adjusted by adjusting the positions of the upper and lower groups of sliders 8 on the upper and lower groups of guide rails 6 so that the connecting shafts 10 rotate in the axial holes 9. Embodiment 3

[0024] On the basis of the second embodiment, in order to limit the slider 8 , a screw hole 11 is opened on the surface of the slider 8 , a hand screw 12 is rotatably connected in the screw hole 11 , and a gasket 13 is fixed on the inner surface of the slider 8 .

[0025] After adjusting the position of the pressure rod 7, the hand screw 12 is screwed to press the hand screw 12 against the surface of the guide rail 6 through the threaded connection between the hand screw 12 and the screw hole 11. At the same time, the end of the slider 8 with the screw hole 11 moves away from the guide rail 6, and the other end of the slider 8 moves toward the guide rail 6, so that the gasket 13 is pressed against the surface of the guide rail 6. The friction between the gasket 13 and the guide rail 6 increases, preventing the slider 8 from moving, thereby achieving the limit of the slider 8.

[0026] In actual use, after placing the movable angle block 3 on the lower die positioning block group 2 set at the top of the bottom plate 1, the two ends of the movable angle block 3 are extended into the movable angle block plug-in holes 5 opened on the surface of the side plate 4, and then the position of the slider 8 on the guide rail 6 is adjusted to adjust the posture of the pressure rod 7, so that the pressure rod 7 is pressed tightly on the surface of the end of the movable angle block 3 away from the lower die positioning block group 2, and then the slider 8 is limited, and the movable angle block 3 is clamped in the middle by the pressure rod 7 and the lower die positioning block group 2, so as to limit the movable angle block 3 and prevent the movable angle block 3 from running around and causing a decrease in production accuracy; two groups of shaft holes 9 are opened on the surface of a group of pressure rods 7, and the two groups of shaft holes 9 are connected with connecting shafts 10, and the two groups of connecting shafts 10 are fixed at On the two groups of sliders 8, the two groups of sliders 8 are respectively slidably connected on the surfaces of the upper and lower groups of guide rails 6. The posture of the pressure rod 7 can be adjusted by adjusting the positions of the upper and lower groups of sliders 8 on the upper and lower groups of guide rails 6 so that the connecting shaft 10 rotates in the shaft hole 9; after adjusting the position of the pressure rod 7, the hand screw 12 is screwed, and the hand screw 12 is pressed against the surface of the guide rail 6 through the threaded connection between the hand screw 12 and the screw hole 11. At the same time, the end of the slider 8 with the screw hole 11 moves in the direction away from the guide rail 6, and the other end of the slider 8 moves in the direction close to the guide rail 6, so that the gasket 13 is pressed against the surface of the guide rail 6, and the friction between the gasket 13 and the guide rail 6 increases, preventing the slider 8 from moving, thereby realizing the limiting of the slider 8.
