Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile production, specifically a four-out-one extrusion supporting double traction machines. Background Technique

[0002] The aluminum profile traction machine clamps the aluminum material from its outlet, then pulls it to a certain length, and sends it to the storage rack after cutting. During the extrusion of aluminum profiles, due to the friction between the aluminum rod and the extrusion tooling (extrusion cylinder, die, extrusion pad, etc.), the flow velocity of the aluminum rod is uneven along the cross-section direction during the extrusion process. By using the traction machine to pull the product, the unevenness of the flow velocity of 5% can be eliminated, so that the flow of the product along the cross-section is relatively uniform, so as to prevent the product from being severely deformed. The traction machine guides the extruded product to move linearly along its guide rail, ensuring the straightness of the product, preventing the product from being distorted, and reducing the damage to the surface of the product. In the aluminum profile processing industry, the aluminum profile extruder is one of the core equipment, and the double traction machines used in the rear end play a crucial role in the precise traction and cutting of aluminum profiles. However, the traditional double traction machine head guided by a telescopic rod, which is widely used, has exposed a series of significant technical defects in practical applications. These defects not only limit the production efficiency and product quality, but also increase the difficulty of equipment maintenance and operation.

[0003] The traditional double traction machine head guided by a telescopic rod is limited in design by the physical length and mechanical structure of the telescopic rod, resulting in obvious limitations in its stroke end point and telescopic length. This limitation is particularly prominent when processing long-size or large-size aluminum profiles, and the effective use stroke is relatively low because it cannot meet the traction requirements of long distance and high precision. When processing aluminum profiles beyond the design range, multiple tractions and cuts are often required, which not only increases the complexity of the production process, but also reduces the overall production efficiency. During the aluminum profile extrusion process, a high-temperature environment is inevitable. In a high-temperature environment, the control accuracy of the traditional double traction machine head guided by a telescopic rod will be severely affected due to factors such as thermal expansion and contraction of materials and decline in lubrication performance. Specifically, problems such as unstable traction force, large fluctuations in traction speed, and inaccurate cutting position occur. In addition, during the traction process, affected by pressure clamping structures such as hydraulic claws, it is extremely easy to cause serious damage to the surface of the profile. These problems directly lead to quality problems such as dimensional deviation and surface quality decline of aluminum profiles, seriously affecting the market competitiveness of products.

[0004] In view of this, research and improvement are carried out on the existing problems, and a four-out-one extrusion supporting double traction machines is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.

[0028] The following describes a one-to-four extrusion supporting double traction machine provided by some embodiments of the present utility model in conjunction with the accompanying drawings.

[0029] Combined Figures 1-5 As shown, the one-to-four extrusion supporting double traction machine provided by the present utility model includes: a traction bed 100, a driving assembly 200, a traction execution assembly 300 and a clamping assembly 400.

The traction execution assembly 300 is fixedly installed on the top surface of the traction bed 100. The traction execution assembly 300 includes scissor linkages 310 and lifting sliders 320. The number of scissor linkages 310 is several and they are connected to each other in sequence. A pulley 311 slidably installed inside the lifting slider 320 is provided at the connection point of adjacent scissor linkages 310.

The clamping assembly 400 includes a collet seat 410, a clamping block 420, a traction rod 430 and a traction slider 440 fixed on the surface of the scissor linkage 310. One end of the traction rod 430 is fixedly connected to the surface of the collet seat 410 and the other end is slidably installed on the surface of the traction slider 440. A slide guide plate 411 is provided on one side of the collet seat 410. A guide slide bar 412 is provided on the surface of the slide guide plate 411. The clamping block 420 is slidably installed on the surface of the guide slide bar 412.

[0030] In this embodiment, the number of lifting sliders 320 is two and they are symmetrically arranged on the upper and lower sides of the scissor linkages 310. The lower lifting slider 320 is fixed to the top surface of the traction bed 100, and both ends of the other lifting slider 320 are slidably sleeved inside the slider seat 220.

[0031] Specifically, by driving the driving assembly 200 to change the distance between the two lifting sliders 320, the phase change guidance of the scissor linkages 310 is realized.

[0032] In this embodiment, the scissor linkages 310 are of an X-shaped double linkage structure, and the midpoints of the two linkages are rotatably connected to each other. The pulleys 311 are located at the ends of the linkages.

[0033] In this embodiment, there are two drive assemblies 200 and they are symmetrically arranged at both ends of the traction actuator 300. The drive assembly 200 includes a reduction motor 210, a sleeve seat 220, and a screw rod 230 fixed to the output end of the reduction motor 210. A threaded sleeve 231 is sleeved on the surface of the screw rod 230. The sleeve seat 220 is fixed to the top surface of the traction bed 100, and the end of the lifting slide bar 320 is slidably abutted against the inner side of the sleeve seat 220.

[0034] Furthermore, the threaded sleeve 231 is fixedly mounted on the surface of the lifting slide bar 320 , and the bottom end of the screw rod 230 is fixedly connected to the output end of the reduction motor 210 .

[0035] Specifically, the two driving components 200 synchronously drive the two ends of the lifting slide bar 320 to move up and down, thereby performing deformation driving of the traction actuator component 300 .

[0036] In this embodiment, one end of the traction rod 430 is slidably connected to the surface of the traction slide 440 , and the sliding direction is perpendicular to the surface of the traction bed 100 .

[0038] Specifically, during the traction process, the friction between the clamping block 420 and the surface of the profile increases the clamping effect of the clamping block 420 sliding along the guide bar 412 on the surface of the profile, thereby achieving anti-slip traction.

[0039] The working principle and use process of this utility model:

[0040] In the initial state of the matching double traction machine, the lifting slide bar 320 is guided by the driving component 200 to slide up to the highest point, the pulleys 311 are in contact with each other, and the scissor-type connecting rod 310 is in the shortest state: in the traction state, the surface of the aluminum profile is clamped by the clamping block 420 inside the clamping sleeve seat 410. During the traction process, the friction between the clamping block 420 and the profile surface causes the clamping block 420 to slide along the guide slide bar 412, thereby increasing the clamping effect on the profile surface, thereby achieving anti-slip traction; the reduction motor 210 drives the screw rod 230 to rotate, and the threaded sleeve 231 drives the lifting slide bar 320 to move downward, so as to compress the scissor-type connecting rod 310 and deform it, so that it stretches and deforms in the transverse direction, and the movement of the clamping block 420 is amplified by the deformation of the scissor-type connecting rod 310, so as to increase the traction movement stroke, realize large-displacement traction, and significantly improve the effective traction stroke.
