Description

Technical Field

[0001] The present invention relates to the technical field of electric power transmission, and in particular to a production device for a high-voltage transmission iron tower. Background Art

[0002] The transmission tower is the supporting point of the overhead line. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower. If two circuits are erected on the transmission tower, it is a double-circuit transmission tower. The transmission tower is a tall structure, which is very sensitive to tilt deformation and has high requirements for uneven foundation settlement. Therefore, the structural form of the transmission tower mainly adopts steel structure. For a long time, the materials used for transmission line towers in my country have been mainly Q235 and Q345 hot-rolled angle steels.

[0003] The cross-section of angle steel is a long strip of steel with two sides perpendicular to each other at right angles. It is widely used in various building structures and engineering structures, including transmission towers.

[0004] At present, when high-voltage transmission towers are produced, their main angle steel structures need to be bent, and then welded together to form a supporting structure after production. Existing bending equipment can only perform stamping processing on the basic shape of the angle steel during production, making it difficult for the produced angle steel to have a high structural assembly flexibility, affecting the rapid construction of the structural assembly.

[0005] Therefore, the present invention proposes a high-voltage transmission tower production equipment. Summary of the invention

[0029] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0030] See also Figure 1-3 As shown, a high-voltage transmission tower production equipment comprises a base 1 and an upper processing table 2 which are arranged in sequence from bottom to top, support frames 3 are fixedly connected to the top two sides of the upper processing table 2, guide sleeves 6 and first guide rods 7 which are matched and arranged are fixedly connected to the top two sides of the base 1, a stamping die 4 and a positioning assembly 5 which are matched and arranged are arranged above the upper processing table 2, a second guide rod 8 is fixedly connected to the top of the base 1, a support seat 9 is sleeved on the second guide rod 8, a connecting seat 10 is fixedly connected to the top of the support seat 9, and a bending seat 11 and a bending block 13 which are matched and arranged are fixedly connected to the top of the connecting seat 10;

[0031] The inner surface of the support frame 3 is provided with a second opening 15 , in which the support plate 12 is movably connected. The surface of the upper processing table 2 is provided with a first opening 14 , and the connecting seat 10 is simultaneously arranged to pass through the first opening 14 .

[0032] In the embodiment of the present invention, the stamping die 4 is vertically arranged in a trapezoidal shape as a whole, and the positioning assembly 5 is composed of a group of connecting rods vertically penetrating the stamping die 4 and a transverse positioning plate at the bottom of the connecting rods. The top of the connecting rods is connected to the external spring rods, and the top of the stamping die 4 is connected to the external hydraulic mechanism. The stamping die 4 is used to achieve the effect of stamping the external material, and the positioning assembly 5 is used to achieve the effect of positioning the external material on the bending seat 11.

[0033] The bending seat 11 is vertically arranged in a trapezoidal shape as a whole, and installation grooves are opened on its two side surfaces corresponding to the bending blocks 13. The top of the bending block 13 is movably embedded in the installation grooves on both sides of the bending seat 11 through the shaft and the torsion spring sleeve. The bending block 13 is inclined along the outer side of the bending seat 11 as a whole, and the bottom end of the bending block 13 is convex in an arc shape. The bending seat 11 is used to achieve the effect of bending and forming the external material, and the bending block 13 is used to achieve the effect of forming an external folding edge at its bottom end when the external material is stamped.

[0034] The external hydraulic mechanism is started to control the stamping die 4 and the positioning assembly 5 to press the external material vertically downward. The positioning assembly 5 first contacts the external material placed on the bending seat 11 to position it. Then, as the stamping die 4 descends, the bending seat 11 cooperates to gradually complete the stamping and bending of the external material. When the stamping die 4 descends and overlaps with the bending seat 11, the overall force on the bending seat 11 increases, and then the bending seat 11 descends. The descent of the bending seat 11 causes the bending block 13 to be blocked by the upper processing table 2 and flipped outward, and then the external material at the position of the bending block 13 is bent outward to form a folded edge, so as to facilitate the subsequent opening of holes at the folded edge position for assembly.

[0035] The first opening 14 is opened at the center of the surface of the upper processing table 2, and the first opening 14 and the bottom of the bending seat 11 are opened with the same width. The connecting seat 10 is arranged in a rectangular seat, and the supporting seat 9 is arranged horizontally as a whole. Compression springs are fixedly connected between its two ends and the upper processing table 2. The second guide rod 8 and the two ends of the supporting seat 9 are movably connected. The connecting seat 10 is used to provide a descending guide for the bending seat 11, and the supporting seat 9 and the second guide rod 8 are used to enhance the descending stability of the bending seat 11.

[0036] When the stamping die 4 descends and overlaps the bending seat 11, causing the overall force on the bending seat 11 to increase, the connecting seat 10 descends along the first opening 14, and then the supporting seat 9 is guided down along the second guide rod 8 to ensure the stability of the descending adjustment of the entire bending seat 11.

[0037] The second opening 15 is vertically opened at the upper inner side of the support frame 3, and the support plate 12 is arranged horizontally in a trapezoidal shape. A matching shaft and a torsion spring sleeve are connected between the inner end of the support plate 12 and the inner wall of the second opening 15. The support plate 12 is flipped as a whole through the shaft and the torsion spring sleeve and embedded in the second opening 15. The support plate 12 is also protruded from the inner side of the support frame 3. The second opening 15 is used to facilitate the flipping and adjustment of the support plate 12, and the support plate 12 is used to place and support external materials.

[0038] The external material is placed between the two groups of support frames 3, and the support plate 12 supports the external material. As the stamping starts, the external material is subjected to force, causing the support plate 12 to flip inward along the second opening 15 to avoid obstruction at both ends of the external material. After the stamping force is applied to both ends of the external material, the support plate 12 returns to its original position.

[0039] The length of both sides of the punching die 4 is the length between the two sides of the bending seat 11 and the top of the bending block 13 .

[0040] When the device is in use, the stamping and bending operation of the external material is completed through the stamping die 4 and the positioning assembly 5 at the upper position, in cooperation with the bending seat 11 at the lower position. After the basic shape of the external material is stamped, a secondary folding bend can be formed at the bottom position of the external material through the bending block 13, so that the external material that has been subsequently stamped has greater assembly flexibility. The user can perform punching operations at the secondary folding bend position, and can also perform more stable welding processing directly through the folding position when assembling the structure.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
