Problems solved by technology

[0004] However, in the process of processing, the inventor found that because the pre-twisted wire itself has the characteristic of rebound, excessive bending is required to form a better U shape, and at this time, the pre-twisted wire will be up and down on both sides of the bending place Offset or crossing occurs, and it is often necessary to manually correct it again before installing it on the guide and ground wires. This method has high labor intensity and low production efficiency.

Embodiment 1

[0041] An automatic bending equipment for pre-twisted metal fittings, refer to figure 1 , including a frame 100, a mounting plate 110 is vertically welded on the frame 100, and a pressing column 111 is connected to the frame 100 by sliding along a direction perpendicular to the mounting plate 110, and two mounting plates 110 are rotatably connected to Contradict the follow-up block 112 on the back of the pre-twisted wire, the follow-up block 112 is provided with a bending block 113 that moves synchronously with it, and both the follow-up block 112 and the bending block 113 have a clamp for engaging with the pre-twisted wire. Connected limit pieces. Through the movement of the pressing column 111, the pre-twisted wire is bent with the bending block 113 and the follower stopper 112, so that both sides of the bent pre-twisted wire can be kept parallel.

[0042] refer to figure 1 , figure 2 , the frame 100 is provided with a driving part 120 for driving the pressing column 111...

Embodiment 2

[0051] The difference from Example 1 is that, referring to Figure 4 , Figure 5 An adjustment block 200 is provided on the lower side of the connecting portion 114, and the resisting roller 130 includes a rotating column 132 that is rotatably connected to the follower block 112 and the bending block 113, and a socket that is integrally arranged on the side of the rotating column 132 close to the connecting portion 114. The column 133 and the adjusting column 134 rotatably connected to the adjusting block 200 and inserted into the sleeve column 133 . The diameter of the rotating post 132 is equal to the diameter of the adjusting post 134 , and the diameter of the sleeve post 133 is smaller than that of the rotating post 132 . The limiting ring groove 131 is a gap between the rotating column 132 and the adjusting column 134 .

[0052] refer to Image 6 , Figure 8 , the connecting part 114 is provided with an adjustment assembly for driving the adjustment block 200 to move ...

Abstract

This application relates to the technical field of pre-twisted wire automatic processing devices, and relates to an automatic bending equipment for pre-twisted wire fittings, including a frame on which a mounting plate is vertically arranged, and the upper edge of the frame is A pressing column is slidably connected to the direction perpendicular to the mounting plate, and two follow-up blocks are connected to the mounting plate for contacting the back of the pre-twisted wire in rotation, and the frame is provided for driving the The driving part that presses the movement of the column, the follow-up block is provided with a bending block that moves synchronously with it, and both the follow-up block and the bending block have a limit for clamping with the pre-twisted wire pieces. The application has the following effects: during the bending process, the pre-twisted wire will be clamped with the follower block and the bending block, and the bending block will complete the final bending action. At this time, both sides of the pre-twisted wire are clamped. On the follower stopper and the bending block, the two sides thereof are kept parallel, and manual re-calibration is not required, and the product can also be kept consistent and can be used normally.

Description

technical field [0001] The present application relates to the technical field of pre-twisted wire automatic processing devices, in particular to an automatic bending equipment for pre-twisted wire fittings. Background technique [0002] Pre-twisted wire is used for connecting fittings for overhead power conductors and power overhead optical cable terminals, suspensions, joints, etc. The initial product is a spiral guard wire for the protection of bare conductor stress concentration locations, electrical corrosion, and arc burn locations. After years of development, pre-twisted wire fittings have been widely used in power transmission and distribution, optical fiber communication, electrified railway, cable TV, construction, agriculture and other fields. [0003] The pre-twisted wire includes tension clamps, suspension clamps, splicing strips, protective lines, etc., among which the tension clamps are used to fix the guide and ground wires to withstand the tension of the gui...
