Technical Field

[0001] The utility model relates to the technical field of door frame production, and particularly relates to a door frame shearing mechanism for stretching hinge installation grooves. Background Art

[0002] A door is composed of a door frame and a door panel. The door panel needs to be rotatably arranged with the door frame to facilitate the opening and closing of the door. Therefore, hinges connected to the door panel need to be installed on the door frame to achieve the rotatable arrangement of the door panel and the door frame.

[0003] Since hinges need to be installed on the door frame, hinge installation grooves for hinge installation need to be stretched and formed on the door frame in advance. In the prior art, stretching and forming hinge installation grooves on the door frame is manually operated by holding relevant equipment manually, which not only consumes a great deal of manpower, but also results in low overall production efficiency due to low automation.

[0004] Therefore, it is necessary to propose a door frame shearing mechanism for stretching hinge installation grooves, which can greatly improve the automation degree, thereby reducing the corresponding manpower consumption and improving the overall production efficiency. Summary of the Utility Model

[0021] It should be noted that in the following solutions, the orientation concepts of "left", "right", "up", "down", "front", "back", "inside", and "outside" are all relative directions, and will not be listed one by one here.

[0022] A door frame shearing mechanism for stretching a hinge installation groove, refer to Figure 1 , including a stretching component 1 and a shearing component 2 arranged in sequence. The stretching component 1 is arranged on a first sliding base plate 3. Two first slide rails 32 are arranged on the lower side of the first sliding base plate 3. Two first sliders 31 are slidably arranged on the first slide rails 32. The first sliders 31 are connected to the lower side of the first sliding base plate 3. The shearing component 2 is arranged on a second sliding base plate 4. Two second slide rails 42 are arranged on the upper side of a third sliding base plate 5. Two second sliders 41 are slidably arranged on the second slide rails 42. The second sliders 41 are connected to the lower side of the second sliding base plate 4. Two third slide rails 52 are arranged on the lower side of the third sliding base plate 5. Two third sliders 51 are slidably arranged on the third slide rails 52. A buffer spring 53 is arranged on the third slide rails 52, and the other end of the buffer spring 53 is connected to the third sliding base plate 5. The extending direction of the third slide rails 52 is the same as the advancing direction of the door frame. The extending directions of the first slide rails 32 and the second slide rails 42 are perpendicular to the advancing direction of the door frame.

[0023] Refer to Figure 2, the stretching assembly 1 includes a stretching substrate 11 disposed on the first sliding substrate 3. A stretching upper die 13, a stretching lower die 12 and a stretching oil cylinder 14 are arranged on the stretching substrate 11 in an up-and-down corresponding manner. The stretching upper die 13 and the stretching lower die 12 are matched in shape. The output end of the stretching oil cylinder 14 is connected to the stretching upper die 13 and is used to drive the stretching upper die 13 to move closer to or away from the stretching lower die 12. First cylinders 15 are arranged on both sides of the stretching lower die 14. The output end of the first cylinder 15 is provided with a top plate 16. The top plate 16 is slidably and abuttedly connected to the lower side of the stretching lower die 12. The lower side of the stretching lower die 12 is an inclined plane.

[0024] When it is necessary to perform embossing and stretching on the hinge installation groove of the door frame, the first cylinder 15 extends, driving the top plate 16 to move and jacking up the stretching lower die 12. The stretching oil cylinder 14 drives the stretching upper die 13 to move downward, and cooperates with the stretching lower die 12 to emboss the hinge installation groove on the door frame. At this time, the door frame continues to move forward. Due to being clamped by the stretching lower die 12 and the stretching upper die 13, the hinge installation groove is stretched at this time. After the embossing and stretching are completed, the stretching oil cylinder 14 and the first cylinder 15 are restored, and the stretching upper die 13 and the stretching lower die 12 move away from each other, and the door frame can pass through the stretching assembly 1.

[0025] Reference Figure 3 and Figure 4 , the shearing assembly 2 includes a second shearing substrate 214 and a first shearing substrate 21 disposed on the second sliding substrate 4. The first shearing substrate 21 and the second shearing substrate 214 are arranged parallel to each other up and down. A material receiving box 215 is arranged at the center of the second shearing substrate 214. An opening is provided at the center of the first shearing substrate 214, and the sheared door frame falls into the material receiving box 215 through the opening. Three shearing bodies 22 are arranged on the first shearing substrate 21. The three shearing bodies 22 are connected in sequence. Through holes 23 matching the shape of the door frame are provided on the three shearing bodies 22. Shearing through holes 26 are provided on the shearing bodies 22 from top to bottom. Three shearing oil cylinders 24 corresponding to the shearing bodies 22 one by one are arranged on the first shearing substrate 21. The output end of the shearing oil cylinder 24 is provided with a shearing piece 25. The shearing piece 25 is slidably arranged through the shearing through hole 26 and is used to shear the door frame. Three second cylinders 27 corresponding to the shearing bodies 22 one by one are arranged on both sides of the first shearing substrate 21. The output end of the second cylinder 27 is provided with a jacking block 28, and a jacking roller 29 is rotatably arranged on the jacking block 28. First notches 210 matching the number and position of the jacking rollers 29 are provided on the first shearing substrate 21. Second notches matching the number, shape and position of the first notches 210 are provided on the lower side of the shearing body 22. Two third cylinders 211 are arranged on the first shearing substrate 21. The output end of the third cylinder 211 is slidably arranged through the shearing body 22. The output end of the third cylinder 211 is provided with a deviation correcting block 212, and a deviation correcting roller 213 is rotatably arranged on the deviation correcting block 212.

[0026] When shearing is required, the second cylinder 27 extends to jack up the shearing body 22, so that the lower wall of the through port 23 abuts against the door frame. At this time, the shearing oil cylinder 24 drives the shearing member 25 to shear the door frame. After the shearing is completed, the shearing oil cylinder 24 and the third cylinder 211 are restored, and the roller 29 is jacked up to move back to the first notch 210 and the second notch, and the shearing body 22 descends, and the door frame no longer abuts against the inner wall of the through port 23, facilitating the advancement of the door frame. When it is found that the moving track of the door frame deviates, the second cylinder 27 works to jack up the roller 29 to hold the door frame and change the moving track of the door frame.
