Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
The invention will be further explained with reference to the following figures and examples:
referring to fig. 1, the present embodiment provides a device for forming a reinforcing ring of a concrete pole, which mainly comprises a cylindrical forming die 1 for forming a cut reinforcing bar section into a profile to form a ring structure. The cylindrical surface outside of the forming die 1 is provided with two forming rollers 2, the two forming rollers 2 are all positioned on the same plane and are close to each other at the initial moment, after the two forming rollers are close to each other, the forming rollers 2 can move back to back along the circumferential direction of the forming die 1, and the forming rollers are always in extrusion contact with the reinforcing steel bars in the moving process to enable the reinforcing steel bars to be gradually wound on the cylindrical surface of the forming die 1, so that a circular hoop reinforcement is formed. When the two forming rollers 2 do the circular motion deviating from each other, the moving speeds of the two forming rollers 2 are preferably the same, specifically, the two forming rollers 2 can be respectively connected to a driving rod, the driving rod is arranged along the radial direction of the forming die 1, one ends of the two driving rods are hinged, the hinged end is located at the circle center of the forming die 1, and each driving rod can be independently provided with common determining elements such as corresponding hydraulic rods, so that the opposite hinged rotation at the same speed is realized. During manufacturing, the middle part of the cut steel bar section is firstly abutted against the cylindrical surface of the forming die 1, then the two forming rollers 2 which are close to each other press the steel bar towards the inner side of the forming die 1, meanwhile, the two forming dies 1 are gradually separated and move back to back, and then the steel bar is gradually compressed and wound on the cylindrical surface of the forming die 1, so that the steel bar is in a circular ring shape, and the gap of the steel bar ring is welded during subsequent processing.
As a specific embodiment, in order to better realize the movement of the forming dies 1 along the circumferential direction of the forming dies 1 and back to back in order to ensure the forming speed and quality of the ring-shaped steel bar when manufacturing the steel bar ring, in particular, as shown in fig. 2-3, a rotatable driving shaft 5 is coaxially arranged above the forming dies 1, and the driving shaft 5 drives the first forming roller 2 to make a circular movement around the axis of the forming die 1 through the connection with the first connecting rod 12; the upper end of the driving shaft 5 is fixed with a first gear 6, the lower end of the driving shaft 5 is provided with a driven gear 7 in a free rotation mode around the driving shaft 5, the first gear 6 and a third gear 9 are in external meshing transmission in a ratio of 1:1 through a second gear 8, and the first gear, the second gear and the third gear are cylindrical gears with the same specification. A fourth gear 11 is fixed at the lower end of a driven shaft 10 for fixing the third gear 9, the fourth gear 11 and the driven gear 7 are in external meshing transmission in a ratio of 1:1, and the external meshing transmission can be realized by meshing two cylindrical gears with the same specification and larger than the first gear, the second gear and the third gear. The driven gear 7 is also fixedly connected with a second connecting rod 13, and the second connecting rod 13 is connected with a second forming roller 2, so that the second forming roller 2 makes circular motion around the axis of the forming die 1, and the back-to-back and same-speed motion of the two forming rollers 2 is realized. In order to make the contact between the forming roller 2 and the reinforcing steel bar smoother, the forming roller 2 is arranged at the free end of the connecting rod and can rotate.
In manufacturing the above-described reinforcing bar ring forming apparatus for a concrete electric pole, as shown in fig. 2, the first connecting rod 12 is in the form ofOne section of the forming roll is horizontally connected to the cylindrical surface of the driving shaft 5, and the other section of the forming roll is vertically arranged and provided with the first forming roll 2. Second connecting rod 13 is the Z style of calligraphy structure that the level was placed, and one of them vertical section connect in on driven gear 7's the bottom face, another vertical section is installed second forming roller 2, the horizontal segment level setting in the middle of two vertical sections just is located the below of driven shaft 10 to do not interfere with driven shaft 10 when making second connecting rod 13 rotate. This kind of structure makes the forming roller 2 drive structure more retrench, and corresponding gear mechanism can not excessively interfere the connecting rod and rotate, and especially second connecting rod 13, it can not receive driven shaft 10's interference, does benefit to the configuration optimization and sets up, reduces manufacturing cost.
Meanwhile, in order to better mount the driven gear 7 such that the driven gear 7 and the first gear 6 are rotatably disposed one on the driving shaft 5 and one rotates in synchronization with the driving shaft 5, as shown in fig. 1, it is characterized in that an annular groove is provided at the driving shaft 5 where the driven gear 7 is located, the annular groove forming a neck portion in which the driving shaft 5 is rotatably mounted.
Because the reinforcing steel bar is not in extrusion contact with the forming roller 2 at the initial moment, the reinforcing steel bar can not be in good contact with the cylindrical side surface of the forming die 1, in order to solve the problem, the bottom end of the forming die 1 is provided with a circular disc 4 with the diameter larger than that of the forming die 1, the circular disc 4 and the forming die 1 form a circular table for placing the reinforcing steel bar, so that the position of the reinforcing steel bar in the forming process is relatively more stable, and the reinforcing steel bar can be better curled into a circular ring shape.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
