Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, in particular to a trimming knife device. Background Art

[0002] The surface of the profile after trimming is smoother and free of burrs and rust. Trimming can remove burrs and irregularities on the edge of the profile, reduce friction and resistance during use, and make it easier to position and fix the profile in subsequent processing, such as welding, punching, bending, etc.

[0003] The aluminum profile trimming die disclosed in the existing patent announcement number CN213793701U includes a second contour screw and a second spring. The second contour screw passes through the upper die seat, the upper pad and the upper clamp in sequence. The second contour screw passes through the second spring and the bottom is fixed to the stripping plate. The second spring is arranged between the upper pad and the stripping plate. After the punching is completed, the first spring lifts the upper die, and the second spring also recovers from the extruded state during punching to the extended state. The elastic force of the extended second spring pushes the stripping plate down and squeezes the stripping plate so that its lower end surface is close to the upper end surface of the lower template.

[0004] Since the blade is a consumable part that needs to be replaced frequently, it is inconvenient to replace the blade during use of the above device, and the practicality still needs to be improved. In view of the above problems, a trimming knife device is proposed. Utility Model Content

The top of the slicing knife 18 is fixedly connected to at least four groups of connecting plates 21. The bottom of the mounting plate 20 is provided with at least four groups of connecting grooves 30. The connecting grooves 30 are clamped with the connecting plates 21. The connecting plates 21 are provided with limit grooves 31 for the limit block 22 to be clamped.

[0026] The mounting plate 20 is fixedly connected with a fixing block 19, the top of the workbench 11 is fixedly connected with a support frame 12, the support frame 12 is installed with a stamping part 13 for moving the fixing block 19 up and down, the support frame 12 is provided with a buffer component for buffering the downward pressure of the fixing block 19, and the bottom of the slicing knife 18 is provided with a lower film plate 17. When in use, the profile to be trimmed is first clamped on the lower film plate 17, and the stamping part 13 starts to work, driving the fixing block 19 to move downward to buffer the downward pressure of the fixing block 19. The punch assembly buffers the downward pressure of the fixed block 19, so that the slicing knife 18 trims the profile. When the slicing knife 18 is replaced, the rotating assembly drives the turntable 28 to rotate. As the turntable 28 rotates, the rotating block 29 slides on the curved surface of the limit block 22, breaking away from the restriction on the limit block 22. The limit assembly limits the sliding of the limit block 22, and the limit block 22 breaks away from the limit groove 31 and slides into the operating box 23 in the card groove 32, moving the slicing knife 18 downward to make the connecting plate 21 break away from the connecting groove 30.

The first spring 26 is fixedly connected to the bottom of the first spring 26. The side of the first spring 26 away from the slider 27 is fixedly connected in the sliding groove 25. The fixed block 19 drives the slider 27 to slide in the sliding groove 25 and squeezes the first spring 26. The fixed block 19 drives the mounting plate 20 to press down, so that the slicing knife 18 trims the profile. The downward pressure of the fixed block 19 can be buffered to reduce the breakage of the slicing knife 18.

[0030] A waste trough 14 is provided on the top of the workbench 11, and a fixing column 24 is provided in the waste trough 14. The lower membrane plate 17 is connected to the fixing column 24 through a nut.

The collection box 16 is located below the waste trough 14. By providing the collection box 16, the waste after cutting can be collected for easy cleaning.

[0032] The working principle of the utility model is as follows: when in use, the profile to be trimmed is first clamped on the lower membrane plate 17, the punching part 13 starts to work, driving the fixed block 19 to move downward, the fixed block 19 drives the slider 27 to slide in the slide groove 25 and squeeze the first spring 26, the fixed block 19 drives the mounting plate 20 to press down, so that the slicing knife 18 trims the profile, and the waste generated by the trimming falls into the collection box 16 through the waste groove 14 for collection. When the slicing knife 18 is replaced, first rotate the positioning The rod 36 is pulled out upwards, and the rotating rod 34 is rotated. The rotating rod 34 drives the rotating disk 28 to rotate. As the rotating disk 28 rotates, the rotating block 29 slides on the curved surface of the limit block 22, and is free from the restriction of the limit block 22. The elastic force of the second spring 38 is used to drive the limit block 22 to slide, so that the positioning block 39 slides in the groove 37, and the limit block 22 is free from the limit groove 31, and slides into the operation box 23 in the card groove 32, and the slicing knife 18 is moved downward, so that the connecting plate 21 is free from the connecting groove 30;

[0033] Place a new slicing knife 18 at the bottom of the mounting plate 20 and move it upward so that the connecting plate 21 is inserted into the connecting groove 30, and the rotating rod 34 is rotated in the opposite direction. The rotating rod 34 drives the turntable 28 to rotate, thereby rotating the rotating block 29, and the rotating block 29 slides along the curved surface of the limiting block 22. The limiting block 22 slides outward in the slot 32 under the force of the rotating block 29 and is inserted into the limiting groove 31. The limiting block 22 drives the second spring 38 to stretch outward to limit the connecting plate 21, and then the positioning rod 36 is inserted into the hole and the positioning hole 33 and rotated to fix it, and the positioning disk 35 is limited to complete the replacement and installation of the slicing knife 18.
