Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum bar processing technical field, especially a kind of automatic barking device for aluminum bar. BACKGROUND

[0002] Aluminum bar is widely used in various fields, and the product obtained after casting aluminum process is aluminum bar. Aluminum bar is a very important production raw material for aluminum profile enterprises. Processing enterprises will purchase aluminum bar according to needs and store it in the warehouse. Aluminum bar is taken out of the warehouse according to needs.

[0003] Aluminum material is easy to oxidize. During transportation and storage, aluminum bar will form a dense layer of aluminum oxide on the surface. The oxidation layer becomes impurities in the later process. Therefore, before processing high-quality products, the raw material will be stripped.

[0004] In the existing aluminum bar stripping process, the bottom of the aluminum bar is equipped with a set of support components that move synchronously during the stripping operation due to the long length of the aluminum bar. However, when stripping different diameter aluminum bars, the required support height of the aluminum bar varies. The current support components generally lack the function of automatically adjusting the height according to the diameter of the aluminum bar. For example, in the actual production of a certain aluminum profile processing enterprise, workers need to manually adjust the position of the support component every time a different diameter aluminum bar is replaced for processing. On average, each adjustment takes about 15 minutes, which not only complicates the operation, but also greatly affects the processing efficiency. According to statistics, due to the manual adjustment of the support component position, the overall processing efficiency is reduced by about 30%. In addition, manual adjustment cannot ensure the accuracy of the support height, which may cause deviation in the position correspondence between the aluminum bar and the cutting ring knife, thereby affecting the stripping quality and increasing the scrap rate. To solve the above problems, an innovative solution is proposed to automatically adjust the height of the support component and improve the efficiency and quality of aluminum bar stripping. SUMMARY

[0005] The utility model aims to provide a kind of automatic barking device for aluminum bar to solve the problems raised in the above background technology.

[0013] Beneficial effects: when the aluminum bar needs to be stripped, the aluminum bar can be placed between the two positioning plates one, and the two positioning plates one are moved by starting the two push oil cylinders one. The movement of the two positioning plates one can adjust the distance between the two positioning plates one. The movement of the two positioning plates one can push the aluminum bar up and down, so as to realize accurate support of aluminum bars of different diameters, ensure the stability of the aluminum bar during processing, and greatly facilitate the subsequent processing operation of the aluminum bar.

[0014] During the stripping process of the aluminum bar, the top block is pushed by the stripping oil cylinder to move the aluminum bar to realize stripping operation.

DETAILED DESCRIPTION

[0021] See Figures 1 to 5 As shown in the figure, an automatic peeling device for aluminum bar comprises a rack 1, an aluminum bar 2, a fixed frame one 3 and a cutting ring knife 4. The fixed frame one 3 is installed on one side of the top of the rack 1. The fixed frame one 3 is provided with a through assembly hole 5. When the aluminum bar 2 needs to be peeled, the cutting ring knife 4 corresponding to the aluminum bar 2 is installed in the through assembly hole 5 through bolts. Then the aluminum bar 2 is pushed into the cutting ring knife 4 to realize peeling.

[0022] The top of the rack 1 is also provided with a support seat one 10 which is slidably arranged. The fixed frame one 3 and the fixed frame two 6 are also provided with a push piece 11 for pushing the support seat one 10. The top of the support seat one 10 is provided with two positioning plates one 12 which are slidably arranged. The aluminum bar 2 is arranged between the two positioning plates one 12. Before the aluminum bar 2 is processed, the push piece 11 is started to move the support seat one 10 to the lower side of the aluminum bar 2. The aluminum bar 2 is directly placed on the two positioning plates one 12 when it is placed, and the two positioning plates one 12 play a supporting role.

[0023] The push piece 11 comprises two slide rods one 111 and a push oil cylinder two 112. The two slide rods one 111 are symmetrically installed between the fixed frame one 3 and the fixed frame two 6. The push oil cylinder two 112 is installed on the bottom side wall of the fixed frame two 6. The piston rod of the push oil cylinder two 112 penetrates the fixed frame two 6. The piston rod of the push oil cylinder two 112 is fixedly connected with the side wall of the support seat one 10. When the support seat one 10 is pushed to move, the push oil cylinder two 112 is started. The piston rod of the push oil cylinder two 112 is extended to push the support seat one 10 to move on the two slide rods one 111. The two slide rods one 111 support the support seat one 10 to ensure that the support seat one 10 moves linearly. The support seat one 10 drives the two positioning plates one 12 on the top to move together. The push oil cylinder two 112 pushes the support seat one 10 to move to the designated position.

[0024] The opposite surface of the two positioning plates one 12 is provided with a slope, and the two slopes are rotatably provided with rollers 121. The aluminum bar 2 is supported and conveyed through the rollers 121. When the aluminum bar 2 is placed on the two positioning plates one 12, it will contact each roller 121. Each positioning plate one 12 is provided with a plurality of rollers 121. When the aluminum bar 2 needs to be pushed into the cutting ring cutter 4 for processing, the aluminum bar 2 will slide on the positioning plate one 12. At this time, the roller (121) rotates around its own axis under the friction of the aluminum bar (2). The rotation of the roller (121) changes the sliding friction between the aluminum bar (2) and the positioning plate one (12) into rolling friction between the roller (121) and the aluminum bar (2). According to the principle of tribology, the rolling friction coefficient is much smaller than the sliding friction coefficient, thereby greatly reducing the friction between the aluminum bar (2) and the positioning plate one (12), making the aluminum bar (2) move more smoothly, reducing the power required to push the aluminum bar (2), and also reducing the scratching and wear of the surface of the aluminum bar (2), improving the product quality.

[0025] The two sides of the support seat one 10 are provided with a push oil cylinder one 13, and the piston rod of the push oil cylinder one 13 is fixedly connected with the positioning plate one 12. The top of the support seat one 10 is symmetrically provided with two sliding grooves one 122, and the bottom of the two positioning plates one 12 is provided with a sliding block one 123. The sliding block one 123 is slidably arranged in the sliding groove one 122. Because the diameters of the aluminum bars 2 to be processed are different, the aluminum bar 2 cannot be ensured to correspond to the center position of the cutting ring cutter 4 when it is placed on the positioning plate one 12 each time. Therefore, the push oil cylinder one 13 on both sides of the support seat one 10 can be started at this time. The two push oil cylinder one 13s are linked and set. The synchronous starting of the push oil cylinder one 13 can push the positioning plate one 12 to move. The positioning plate one 12 can drive the sliding block one 123 at the bottom to slide in the sliding groove one 122. The sliding block one 123 plays a role of limiting the movement of the positioning plate one 12. The movement of the two positioning plates one 12 can adjust the distance between the two positioning plates one 12. The movement of the two positioning plates one 12 can push the aluminum bar 2 to move up and down, so as to support the aluminum bar 2 of different diameters and facilitate the processing of the aluminum bar 2.

[0026] The other end of the rack 1 is provided with a fixed frame two 6, and a stripping oil cylinder 7 is installed on the side wall of the fixed frame two 6. The piston rod of the stripping oil cylinder 7 penetrates through the fixed frame two 6, and a top block 8 is connected to the piston rod of the stripping oil cylinder 7. The aluminum bar 2 is arranged between the top block 8 and the fixed frame one 3. When the aluminum bar 2 is installed through the two positioning plates one 12, the stripping oil cylinder 7 can be started. The stripping oil cylinder 7 is fixedly connected to the top block 8 through a connecting rod 21. The piston rod of the stripping oil cylinder 7 drives the connecting rod to move. The connecting rod 21 drives the top block 8 to move. The end of the top block 8 close to the aluminum bar 2 is provided with a buffer 9. When the stripping oil cylinder 7 drives the top block 8 to contact the aluminum bar 2, the buffer 9 first contacts the aluminum bar 2. Through the arrangement of the buffer 9, the rigid connection between the top block 8 and the aluminum bar 2 is changed into a flexible connection, which is more convenient for the movement of the aluminum bar 2 compared with the traditional rigid connection.

[0027] The buffer 9 includes a buffer spring 91 and a buffer block 92. The side wall of the top block 8 is provided with a buffer groove 93. The buffer spring 91 is arranged in the buffer groove 93. One end of the buffer spring 91 is fixed to the side wall of the buffer groove 93. The buffer block 92 is slidingly arranged in the buffer groove 93. The other end of the buffer spring 91 is fixedly connected to the side wall of the buffer block 92. During the movement of the top block 8, the buffer block 92 on the side of the top block 8 first contacts the aluminum bar 2. After the buffer block 92 contacts the aluminum bar 2, the buffer block 92 is extruded to move into the buffer groove 93. The buffer block 92 extrudes the buffer spring 91. Through the arrangement of the buffer block 92 and the buffer spring 91, the rigid connection with the aluminum bar 2 is changed into a flexible connection.

[0028] Two sliding rods two 19 are further arranged between the fixed frame one 3 and the fixed frame two 6. The two sliding rods two 19 are slidingly provided with a positioning connecting plate 20. The bottom of the positioning connecting plate 20 is fixedly connected to the connecting rod 21. The connecting rod 21 further drives the positioning connecting plate 20 to move on the two sliding rods two 19 during the movement of the connecting rod 21. The positioning connecting plate 20 supports and positions the connecting rod 21.

[0029] The side wall of the fixed frame one 3 is further provided with a support base two 14, the top of the support base two 14 is slidably provided with two positioning plates two 15, the support base two 14 is arranged on the side wall of the fixed frame one 3, the two positioning plates two 15 correspond to the through assembly hole 5, the top of the support base two 14 is provided with a sliding groove two 16, the bottom of the positioning plate two 15 is fixedly provided with a sliding block two 17, the sliding block two 17 is slidably arranged in the sliding groove two 16, the two sliding grooves two 16 are both provided with a connecting spring 18, one end of the connecting spring 18 is fixed on the side wall of the sliding groove two 16, the other end of the connecting spring 18 is fixedly connected with the side wall of the sliding block two 17, when the aluminum bar 2 is stripped and passes through the fixed frame one 3, the aluminum bar 2 will be in contact with the two positioning plates two 15, the two positioning plates two 15 support the processed aluminum bar 2, the positioning plate two 15 is adjusted left and right through the sliding block two 17 and the connecting spring 18 at the bottom. Since the positioning plate one 12 mainly plays a positioning and supporting role on the aluminum bar 2, therefore the positioning plate one 12 is adjusted in position through the pushing oil cylinder one 13, so as to prevent the positioning plate one 12 from being displaced during use, and the positioning plate two 15 mainly plays a temporary supporting role on the processed aluminum bar 2, so that the aluminum bar 2 can be moved to the collecting frame, therefore the positioning plate two 15 is moved through the connecting spring 18 at the bottom, and supports the aluminum bar 2 with different diameters.
