Description

Technical Field

[0001] The present application relates to the technical field of extruders, and in particular to an extrusion head clamping mechanism of an extruder. Background Art

[0002] The extrusion head is set at the end of the extrusion rod of the extruder to prevent excessive wear and deformation caused by direct contact between the extrusion rod and the billet. Because the extrusion head is in direct contact with the billet and the extrusion barrel during operation, it will inevitably be worn or chipped and cannot be used any longer. Therefore, the damaged extrusion head needs to be replaced frequently.

[0003] At present, it is inconvenient to replace the extrusion head. Since the extrusion head is directly fixed on the mounting plate, the extrusion head cannot be quickly removed from the mounting plate when the extrusion head is replaced, resulting in low replacement efficiency of the extrusion head and affecting the use of the press. Therefore, an extrusion head clamping mechanism of the extruder is designed to solve the above-mentioned problems. Utility Model Content

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses an extrusion head clamping mechanism of an extruder. Figure 1-4The extrusion head clamping mechanism of the extruder includes a mounting plate 1, and the mounting plate 1 is slidably connected to a movable plate 3 on both sides. The lower end of the movable plate 3 is fixedly connected to a clamping plate 31. The clamping plate 31 and the movable plate 31 are both arc-shaped. The arc-shaped setting fits the circular extrusion head 2 better, which is conducive to the installation and fixation of the extrusion head 2.

[0023] The clamping plate 31 clamps the extrusion head 2, and the clamping plates 31 are close to each other and fixedly connected to the plug-in plate 5 and the plug-in frame 4. The plug-in frame 4 and the plug-in plate 5 are respectively arranged on different movable plates 3. The plug-in plate 5 and the plug-in frame 4 are symmetrically arranged, and when the clamping plate 31 and the movable plate 3 are used to clamp the extrusion head 2, the plug-in plate 4 and the plug-in frame 5 are in a mutually clamped state;

[0024] By adopting the above technical solution, a mounting groove is provided on the side of the insert frame 4 close to the insert board 5, and a plurality of fixing grooves are provided on the upper end of the insert frame 4, and the fixing grooves and the mounting grooves are connected. Figure 2 As shown, generally there are three, wherein the fixed groove is slidably connected to the limit block 41, and the limit block 41 is trapezoidal, such as Figure 4 Three fixing grooves and a stopper 41 are provided, and small adjustments can be made according to the diameter of the extrusion head 2, so that the extrusion head 2 within a certain diameter range can be adapted to the installation and use of the clamping mechanism.

[0025] By adopting the above technical solution, the upper end of the limit block 41 is fixedly connected to the No. 1 spring 42, and the upper end of the No. 1 spring 42 is fixedly connected to the inner wall of the fixing groove. The No. 1 spring 42 can push the limit block 41 to recover again after being squeezed into the fixing groove, so that the limit block 41 moves to the initial position; the middle part of the upper end of the limit block 41 is fixedly connected to the pull rod 43, which is T-shaped, and the upper end of the pull rod 43 is located outside the insertion frame 4. The pull rod 43 is used to pull the limit block 41 so that the limit block 41 can rise and enter the fixing groove.

[0026] By adopting the above technical solution, a limiting groove 51 is provided on the upper end of the plug board 5 close to the plug frame 4 , and the limiting groove 51 is plugged into the limiting block 41 .

[0027] The implementation principle of the extrusion head clamping mechanism of the extruder in the embodiment of the present application is: when the damaged extrusion head 2 needs to be replaced, the limit block 41 plugged into the limit groove 51 can be pulled. Specifically, the pull rod 43 of its section is pulled to make the pull rod 43 drive the limit block 41 to rise and separate from the limit groove 51, and then the insertion frame 4 and the insertion plate 5 are pulled horizontally to separate the insertion frame 4 from the insertion plate 5, and at the same time, the two movable plates 3 and the clamping plate 31 are moved away from each other, so that the slider 32 moves in the slide groove and squeezes the No. 2 spring 6 to contract.

[0028] The extrusion head 2 is removed and a new extrusion head 2 is placed in the middle of the lower end of the mounting plate 1. Then, the two movable plates 3 are loosened to allow the No. 2 spring 6 to recover and push the slider 32 to move. The slider 32 drives the movable plate 3 at the lower end to move and approach each other, so that the insertion frame 4 and the insertion plate 5 approach each other. The clamping plate 31 at the bottom of the movable plate 3 moves along, approaches and lifts the extrusion head 2, and the insertion plate 5 moves and enters the insertion frame 4, so that the insertion plate 5 squeezes the limit block 41. Since the limit block 41 is inclined on one side, it will rise after being squeezed, and squeeze the No. 1 spring 42 to contract until the limit groove 51 of the insertion plate 5 is aligned with the limit block 41. At this time, the No. 1 spring 42 recovers and pushes the limit block 41 down and enters the limit groove 51, so that the insertion plate 5 is fixed and cannot be removed from the insertion frame 4, thereby completing the installation and replacement of the extrusion head 2.
