Description

Technical Field

[0001] The invention relates to the technical field of wire material processing equipment, and in particular to a flat wire straightening and centering mechanism. Background Art

[0002] As a multi-core cable, flat cable was first used in electronic computers and electronic instruments. Due to its advantages such as easy bending and small wiring space, it is also widely used in civilian appliances such as telephones and recorders. The application of insulation displacement connectors makes the termination of flat cables extremely convenient and reliable. At the same time, it also puts forward higher requirements on the geometric dimensions such as the center distance tolerance, center distance cumulative error and insulation thickness of flat cables, which increases the difficulty of manufacturing flat cables. The molding method of flat cables is to sandwich a group of core wires arranged evenly at a certain distance between two pieces of plastic film, and bond the three together into a flat cable by certain means. There are two problems to be solved during molding. One is how to produce two layers of plastic film that can bond or fuse to each other, and the other is to ensure that a group of wires always maintain a certain distance and are evenly arranged.

[0003] In the production and processing of flat wires, straightening and centering are important process steps, which directly affect the quality of the wire and the efficiency of subsequent processing. At present, there are some flat wire straightening and centering devices on the market, but they generally have problems such as low precision, poor stability, and complex operation.

[0039] Preferably, the scraper 16 is arranged obliquely and fits tightly against the outer wall of the upper straightening bearing 3 or the lower straightening bearing 4, so that the surface of the drum can be cleaned during its rotation.

[0040] Preferably, there are two mounting connectors 14 connecting the upper straightening bracket 1 and the lower straightening bracket 2, and the two mounting connectors 14 can be connected by a fixing screw 17. When the fixing screw 17 is connected, the mounting connector 14 is in a working state, and the parallelogram is converted into a fixed parallelogram structure, which can ensure that the upper and lower straightening brackets are in a working position, facilitate subsequent fine-tuning of each bolt, and the structure reaches the best working state.

[0041] The specific working principle and use method of the present invention are as follows: the upper straightening bracket 1 and the lower straightening bracket 2 are connected to the head connecting frame 15 connected by the installation connector 14 and the wire production head, the upper straightening bracket 1 and the lower straightening bracket 2 are opened, so that the flat wire can be quickly threaded, and after threading, the fine adjustment mechanism can be closed to achieve the optimal shaping state, the upper straightening bracket 1 and the lower straightening bracket 2 are connected by bolts, the upper straightening bearing 3 and the lower straightening bearing 4 are staggered, and the rotating No. 1 moving steel ball The screw 9 can adjust the height of the bottom upper straightening bearing 3, and the second dynamic steel ball screw 10 can be rotated to adjust the height of the lower straightening bearing 4 as needed. The locking bolts connecting the upper straightening bracket 1 and the lower straightening bracket 2 also use dynamic steel column bolts, which can always maintain flat contact with the contact surface. The adjustment method is that when the center of the flat line is too high, loosen the locking screw of the lower straightening bracket 2, lock the locking bolt of the upper straightening bracket 1 to the center position, and then lock the lower straightening bracket 2. The locking screws are tightened. If the center of the flat wire is too low, adjust it in the opposite way. The centering guide wheels 12 at the horizontal centering supports 11 on both sides can realize horizontal control of the flat wire. When the horizontal center is not in position, the bolts on the horizontal centering support 11 can be loosened to adjust the position of the guide wheels to realize left and right center adjustment of the flat wire, ensuring that the flat wire always maintains a horizontal center position during the straightening process. The mounting connectors 14 of the upper straightening bracket 1 and the lower straightening bracket 2 are two sets of opposing parallelogram linkage mechanisms. When on standby and threading, the parallelogram mechanism can be opened by loosening the fixing screws 17 for easy operation. When working, the parallelogram linkage mechanism can be adjusted to the center position and the fixing screws 17 can be locked for positioning. The upper straightening bearing 3 and the lower straightening bearing 4 are both provided with scrapers 16, i.e., cleaning mechanisms. A collecting trough is provided at the upper straightening bracket 1. The collecting trough avoids the leakage holes on both sides of the flat wire. The scraped impurities fall into the collecting trough, and the impurities at the lower straightening bracket 2 are directly scraped off without affecting the flat wire.
