Description

Technical Field

[0001] The utility model belongs to the technical field of profile straightening machines, and in particular relates to a material loading and positioning device used for profile straightening processing. Background Art

[0002] In the field of profile processing, profile stretching machines are a key equipment widely used in the plastic forming process of metal materials, especially for those profiles that may be bent or deformed during production or transportation, such as aluminum profiles, steel bars, etc., to correct their straightness to meet the precise requirements of subsequent processing or assembly. Traditional profile stretching machines are usually equipped with a tooth plate clamping mechanism, which fixes the profile through a strong clamping force, and then eliminates its internal stress and external bending through a stretching action to ensure the straightness and dimensional accuracy of the profile.

[0003] However, in the existing profile stretching machine design, although the importance of profile side positioning has been noted, a positioning mechanism has been equipped to assist in accurately pushing the profile to the bottom of the tooth plate and achieving preliminary alignment. This design has greatly improved the accuracy and efficiency of profile placement. However, a significant drawback is that most of these systems ignore the precise positioning and arrangement of the axial ends of the profile. Specifically, when the profile is fed into the stretching machine and aligned by the side positioning mechanism, its two ends often have unnecessary redundant lengths because they are located outside the stretching area. This redundant length eventually needs to be removed by cutting, which not only adds additional processing steps, but also leads to a large waste of raw materials, which is not in line with the principle of pursuing efficiency and saving resources in modern production.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

The feeding mechanism is located at the front side of the tooth plate clamping table, and the feeding mechanism is used to feed the profile to the tooth plate clamping table. The positioning mechanism includes two groups of side thrust assemblies, and the two groups of side thrust assemblies are located on both sides of the tooth plate clamping table and are symmetrically assembled about the tooth plate clamping table. The side thrust assembly includes a second thrust cylinder, the second thrust cylinder is connected to a lateral positioning seat, and the lateral positioning seat is provided with a lateral positioning surface for positioning the side of the profile, and the lateral positioning seat is equipped with a third thrust cylinder, the third thrust cylinder is connected to an axial positioning seat, and the axial positioning seat is provided with an axial positioning surface for positioning the end face of the profile.

[0007] Preferably, the positioning mechanism further comprises a first push cylinder, the first push cylinder is connected to a retracting slide, and the second push cylinder is assembled on the retracting slide. This design enables the lateral positioning seat to retreat after the positioning operation, making way for the feeding mechanism to feed the material, thereby avoiding interference between the feeding mechanism and the positioning mechanism.

The feeding mechanism 20 is located at the front side of the tooth plate clamping platform 11, and is used to feed the profile to the tooth plate clamping platform 11. The positioning mechanism includes two sets of side push assemblies 30, which are located on both sides of the tooth plate clamping platform 11 and are symmetrically assembled about the tooth plate clamping platform 11.
