Description

Technical Field

[0001] The invention relates to a single-axis chain-type traction machine head structure, in particular to a single-axis chain-type traction machine head structure of a three-head traction machine, and belongs to the technical field of aluminum profile production equipment. Background Art

[0002] During the extrusion process of aluminum alloy profiles, the profile must be interrupted after each aluminum rod is extruded.

[0003] In order to facilitate the post-processing such as transmission and straightening. In addition, traction assistance is very important in the extrusion process, especially for the currently popular multi-hole die extrusion and some profiles that are difficult to extrude. Good and effective traction assistance can not only ensure the discharge of the profile, but also improve production efficiency and yield rate.

[0004] Traditional traction machines are mostly single-head traction machines. When traction reaches a certain position, the single-head traction machine puts down the profile, then returns to the starting point of traction and repeats the work. This single traction method is very inefficient. There are also double-head traction machines in the existing technology. Their working form is: the previous traction device pulls the profile over, and at a certain place, the pulled profile is handed over to another traction device for continued traction, and the previous traction device returns to complete the relay of the profile. Although this method can achieve uninterrupted traction, the traction machine will collide with the traction machine during the relay process, and the traction machine will pause when the profile is handed over, causing the profile to bend in the axial direction. At the same time, scratches are easily caused on the surface of the profile, affecting the quality of the profile.

[0005] The three-head traction machine currently on the market usually includes a frame, an upper track and a lower track are arranged on the frame, and an upper traction head and a lower traction head are arranged on the upper track and the lower track respectively, and the upper traction head and the lower traction head can alternately perform traction operations, so that the production of profiles is uninterrupted, continuous operation is guaranteed, and production efficiency is improved, which well solves the above technical problems. However, in order to enable the upper traction head and the lower traction head to smoothly alternate their working positions, the existing three-head traction machine usually needs to add a transverse movement mechanism or a lifting mechanism to the traction head, and through the transverse movement mechanism or the lifting mechanism, one of the traction heads makes room for the other traction head, so as to smoothly complete the alternation of working positions, which makes the structure of the whole set of mechanisms complicated and greatly increases the production cost.

[0006] The invention patent with application number 201910710981.1 discloses a three-head traction machine traction head structure, which includes a frame, a support shaft is fixedly arranged on the frame, an intermediate support plate and a gear are mounted on the support shaft, the gear is located above the intermediate support plate, the intermediate support plate is rotatably connected to the support shaft, and the gear is fixedly connected to the support shaft; a frame is arranged on the intermediate support plate, a worm gear second motor is arranged on the frame, the worm gear second motor includes an outer output end and an inner output end, a tooth claw assembly is arranged on the outer side of the frame, the outer output end is connected to the tooth claw assembly through a connecting rod mechanism, a fork assembly is arranged on the inner output end, a rack that can be translated left and right is arranged on the intermediate support plate, the rack is located between the frame and the gear, a card plate is arranged on the top of the rack, the rack cooperates with the gear, and the card plate cooperates with the fork assembly. The above-mentioned traction head structure can realize the rotation of the entire traction head through the power of the clamping mechanism, thereby making room for another traction head when alternating working positions, eliminating the existing transverse movement mechanism or lifting mechanism, simplifying the overall structure, and reducing the manufacturing cost. However, the above-mentioned structure has very high requirements for the dimensional accuracy of the fork assembly, the clamping plate, the gear and the rack. When the processing accuracy of the above-mentioned components is not enough or a certain amount of wear occurs during use, the components cannot be accurately matched, resulting in the power of the clamping structure being unable to accurately and smoothly complete the rotation of the traction head.
