Description

Technical Field

[0001] This utility model relates to the field of track link forging technology, specifically to an automated track link forging device. Background Technology

[0002] Track links are the connecting parts in the tracks of engineering machinery. They are made by heating a metal blank to a temperature higher than the material's recrystallization temperature and then using a mold to plastically shape the metal blank into a forging shape. This process is generally a process of forging and stamping the metal blank.

[0003] During the forging and stamping process of metal blanks, some oxide layer impurities will fall off the surface of the metal blanks due to the force applied. These oxide layer impurities will be forged and adhered to the die. In the existing technology, in order not to affect the forging and stamping quality of the subsequent track links, these oxide layer impurities will be cleaned. The cleaning method is to remove the track links from the die and then use air blowing to clean the impurities. However, since the oxide layer impurities are adhered to the die, the air blowing method is prone to incomplete cleaning and cannot guarantee a complete cleaning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated forging device for track links.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated forging device for track links includes:

[0007] Base;

[0008] A forging mechanism, comprising two vertical plates fixedly connected to the upper end of a base, with a lower template fixedly connected to the upper end of the two vertical plates via a bracket, and a forging groove provided at the upper end of the lower template.

[0009] The cleaning mechanism includes an L-shaped plate fixedly connected to the upper end of the base. Two electric push rods are fixedly connected to the side wall of the L-shaped plate away from the lower template. The movable ends of the two electric push rods are fixedly connected to a hollow plate. A plurality of first bristles are fixedly connected to the lower end of the hollow plate. The side walls of the plurality of first bristles are all in contact with the upper surface of the lower template.

[0010] Preferably, the forging mechanism further includes two hydraulic cylinders fixedly connected to the upper end of the L-shaped plate, and the movable ends of the two hydraulic cylinders are jointly fixedly connected to a forging head that faces the forging groove.

[0011] Preferably, an air inlet pipe is fixedly connected to the top of the hollow plate, and multiple air jet holes are evenly distributed at the bottom of the hollow plate.

[0012] Preferably, the cleaning mechanism further includes a through groove formed in the side wall of the L-shaped plate, two rectangular rods are fixedly connected to the top of the through groove, a horizontal plate is slidably connected to the side walls of the two rectangular rods, a fixed plate is fixedly connected to the upper end of the horizontal plate, a plurality of second bristles are fixedly connected to the side wall of the fixed plate, the side walls of the plurality of second bristles are in contact with the inner side wall of the forging groove, and the lower end of the horizontal plate is elastically connected to the upper end of the base through a plurality of springs.

[0013] Preferably, the hollow plate is provided with a control mechanism, the control mechanism including a first wedge plate fixedly connected to the side wall of the hollow plate away from the lower template, the first wedge plate being located in the through groove, and a second wedge plate cooperating with the first wedge plate being fixedly connected to the upper end of the horizontal plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. A cleaning mechanism is set up, and the two electric push rods are adjusted to extend and retract intermittently, so that the hollow plate drives multiple first brush bristles to move back and forth on the upper surface of the lower template to remove oxide layer impurities on the lower template. At the same time, gas flows out through multiple air jet holes to blow out the loose oxide layer on the lower template, thereby increasing the cleaning effect on impurities on the lower template. This avoids the problem that the existing technology only uses air blowing to clean impurities, but because the oxide layer impurities adhere to the mold, the air blowing method is prone to incomplete cleaning and cannot guarantee a comprehensive cleaning.

[0016] 2. During the back-and-forth movement of the hollow plate, the fixed plate drives multiple second brush bristles to move up and down intermittently, which can clean the inner wall of the forging groove. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 An automated forging device for track links includes a base 1.

[0025] The forging mechanism includes two vertical plates 2 fixedly connected to the upper end of the base 1. The upper ends of the two vertical plates 2 are fixedly connected to a lower template 3 through a bracket. The upper end of the lower template 3 is provided with a forging groove 4. The forging mechanism also includes two hydraulic cylinders 6 fixedly connected to the upper end of the L-shaped plate 5. The movable ends of the two hydraulic cylinders 6 are fixedly connected to a forging head 7 that is directly opposite to the forging groove 4.

[0026] The cleaning mechanism includes an L-shaped plate 5 fixedly connected to the upper end of the base 1. Two electric push rods 8 are fixedly connected to the side wall of the L-shaped plate 5 away from the lower template 3. The movable ends of the two electric push rods 8 are fixedly connected to a hollow plate 9. Multiple first brush bristles 10 are fixedly connected to the lower end of the hollow plate 9. The side walls of the multiple first brush bristles 10 are all in contact with the upper surface of the lower template 3.

[0027] An air inlet pipe 12 is fixedly connected to the top of the hollow plate 9, and multiple air jet holes 11 are evenly distributed at the bottom of the hollow plate 9.

[0028] Furthermore, after the track link is forged and stamped, it is removed from the lower template 3. Then, the two electric push rods 8 are intermittently extended and retracted, causing the hollow plate 9 to drive multiple first bristles 10 to move back and forth on the upper surface of the lower template 3 to remove oxide layer impurities on the lower template 3. At the same time, the inlet of the air pipe 12, away from the hollow plate 9, is connected to the output port of an external air pump. At this time, high-pressure gas can be pumped into the hollow plate 9 through the air pipe 12. Then, the gas flows out through multiple jet holes 11, blowing out the loose oxide layer on the lower template 3, increasing the cleaning effect on impurities on the lower template 3. This avoids the problem in the prior art where only air blowing is used to clean impurities, but because the oxide layer impurities adhere to the mold, air blowing can easily lead to incomplete cleaning and cannot guarantee comprehensive cleaning.

[0029] The cleaning mechanism also includes a through groove 13 opened on the side wall of the L-shaped plate 5. Two rectangular rods 14 are fixedly connected to the top of the through groove 13. A horizontal plate 15 is slidably connected to the side walls of the two rectangular rods 14. A fixed plate 17 is fixedly connected to the upper end of the horizontal plate 15. Multiple second bristles 18 are fixedly connected to the side wall of the fixed plate 17. The side walls of the multiple second bristles 18 are in contact with the inner side wall of the forging groove 4. The lower end of the horizontal plate 15 is elastically connected to the upper end of the base 1 through multiple springs 16.

[0030] The hollow plate 9 is equipped with a control mechanism, which includes a first wedge plate 19 fixedly connected to the side wall of the hollow plate 9 away from the lower template 3. The first wedge plate 19 is located in the through groove 13. A second wedge plate 20 that cooperates with the first wedge plate 19 is fixedly connected to the upper end of the horizontal plate 15. Figure 2 (As shown).

[0031] As the hollow plate 9 moves towards the lower template 3, the first wedge plate 19 moves away from the second wedge plate 20. At this time, the horizontal plate 15 gradually moves upward under the action of multiple springs 16, causing the fixing plate 17 and multiple second bristles 18 to enter the forging groove 4. It should be noted that after the first wedge plate 19 separates from the second wedge plate 20, the horizontal plate 15 moves to the top, and the upper end of the fixing plate 17 is flush with the upper end of the lower template 3, which does not affect the movement of the hollow plate 9. When the hollow plate 9 moves away from the lower template 3, the first wedge plate 19 gradually presses against the second wedge plate 20. At this time, the horizontal plate 15 drives the fixing plate 17 to move downward until the initial position (e.g., Figure 2 As shown), at this time, the multiple second brush bristles 18 are away from the forging groove 4. Thus, during the back-and-forth movement of the hollow plate 9, the fixed plate 17 drives the multiple second brush bristles 18 to move up and down intermittently, which can clean the inner wall of the forging groove 4.

[0032] When forging and stamping the track link, the metal blank is placed at a specific position on the lower template 3, and then the two hydraulic cylinders 6 are adjusted to extend, driving the forging head 7 to move down. At this time, under the action of the forging head 7 and the forging groove 4, the metal blank can be forged and stamped to form, thus completing the production of the track link.

[0033] After the track link is forged and stamped, it is removed from the lower template 3. Then, the two electric push rods 8 are adjusted to extend and retract intermittently, so that the hollow plate 9 drives multiple first bristles 10 to move back and forth on the upper surface of the lower template 3 to remove oxide layer impurities on the lower template 3. At the same time, the inlet of the air pipe 12 is connected to the output port of an external air pump. At this time, high-pressure gas can be pumped into the hollow plate 9 through the air pipe 12. Then, the gas flows out through multiple jet holes 11 to blow out the loose oxide layer on the lower template 3, increasing the cleaning effect on impurities on the lower template 3.

[0034] As the hollow plate 9 moves towards the lower template 3, the first wedge plate 19 moves away from the second wedge plate 20. At this time, the horizontal plate 15 gradually moves upward under the action of multiple springs 16, causing the fixing plate 17 and multiple second bristles 18 to enter the forging groove 4. As the hollow plate 9 moves away from the lower template 3, the first wedge plate 19 gradually presses against the second wedge plate 20. At this time, the horizontal plate 15 drives the fixing plate 17 to move downward until the initial position (e.g., Figure 2 As shown), at this time, the multiple second brush bristles 18 are away from the forging groove 4. Thus, during the back-and-forth movement of the hollow plate 9, the fixed plate 17 drives the multiple second brush bristles 18 to move up and down intermittently, which can clean the inner wall of the forging groove 4. This avoids the situation in the prior art where only air blowing is used to clean impurities. However, since the oxide layer impurities adhere to the mold, using air blowing can easily lead to incomplete cleaning and cannot guarantee a complete cleaning.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
