Description

Technical Field

[0001] This utility model relates to the field of mold trimming equipment technology, and in particular to a trimming floating blade block. Background Technology

[0002] Iron or aluminum shavings are generated during trimming because the cutting edge has a step difference and is partially torn. The floating blade can ensure that there is no step difference when trimming the entire circle, which can reduce the generation of iron and aluminum shavings. However, since the floating blade is movable, lateral forces will be generated during trimming due to punching force and other reasons, which will result in trimming burrs and greatly reduce the service life of the floating blade.

[0003] For example, CN205763287U, published on December 7, 2016, discloses a trimming waste blanking die, including an upper die base and a lower die base. The upper die base is provided with a trimming upper die and an upper waste cutter, and the lower die base is provided with a trimming lower die and a lower waste cutter. It also includes a floating block, with the upper waste cutter mounted on the upper die base via the floating block. The floating block disclosed above is easily subjected to lateral shearing forces when moving, resulting in a shorter service life and poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a more practical floating trimming blade block. This invention uses a guide block to guide the relative displacement between the fixed and moving blade blocks, thereby preventing the fixed blade block from shaking under lateral shearing force, ensuring the normal operation of the trimming blade block, and resulting in better trimming effects.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a trimming floating blade block, including a base, on which a movable blade block and a fixed blade block are provided, and a guide block is provided on the movable blade block, and the guide block abuts against the fixed blade block.

[0006] The movable blade block is provided with a movable groove, and the fixed blade block is disposed in the movable groove.

[0007] The guide block is disposed between the moving cutter block and the fixed cutter block, and the guide block is disposed within the moving groove.

[0008] The guide block is connected to the movable blade block by bolts.

[0009] The guide block has an L-shaped cross-section.

[0010] The surface of the guide block that contacts the fixed blade block is smooth.

[0011] The beneficial effects of this utility model are:

[0012] When relative displacement is detected between the fixed and moving blades during the trimming process, the fixed blade is guided by a guide block to prevent it from being subjected to lateral shearing forces. This prevents the fixed blade from becoming immobile after long-term use, thus ensuring stable trimming by both the fixed and moving blades, resulting in higher trimming quality and greater practicality.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] like Figure 1-2 As shown, a trimming floating blade block includes a base 1, on which a movable blade block 2 and a fixed blade block 3 are provided. The movable blade block 2 is provided with a guide block 4, which abuts against the fixed blade block 3, thereby guiding the fixed blade block 3 when it moves relative to the movable blade block 2.

[0019] In use, the base 1 moves, causing the movable blade block 2 and the fixed blade block 3 to move for trimming. When the movable blade block 2 and the fixed blade block 3 come into contact with the mold, the fixed blade block 3 remains stationary while the movable blade block 2 moves with the base 1. At this time, the fixed blade block 3 and the movable blade block 2 experience relative displacement. The guide block 4 then guides the fixed blade block 3 to prevent it from being subjected to lateral shearing force, thus preventing it from moving. This allows the fixed blade block 3 and the movable blade block 2 to perform trimming work stably, resulting in better trimming quality and higher practicality.

[0020] The movable blade block 2 is provided with a movable groove 5, and the fixed blade block 3 is set in the movable groove 5, so as to ensure that the movable blade block 2 and the fixed blade block 3 move together to perform trimming work. When the movable blade block 2 and the fixed blade block 3 move relative to each other, the fixed blade block 3 moves in the movable groove 5.

[0021] The guide block 4 is positioned between the moving cutter block 2 and the fixed cutter block 3, and is positioned within the moving groove 5, thereby preventing the guide block 4 from obstructing the movement of the moving cutter block 2 and ensuring that the fixed cutter block 3 and the moving cutter block 2 can stably perform the trimming work.

[0022] The guide block 4 is connected to the movable blade block 2 by bolts 6, thereby enabling convenient assembly and disassembly of the guide block 4 on the movable blade block 2. Specifically, the guide block 4 is provided with a through hole for the bolts 6 to pass through, and the movable blade block 2 is provided with a threaded hole that mates with the bolts 6.

[0023] Specifically, the guide block 4 has an L-shaped cross-section, which ensures that the end of the guide block 4 is in stable contact with the guide blade block 3.

[0024] The surface of the guide block 4 that contacts the fixed blade block 3 is smooth, thereby ensuring that the guide block 4 can stably perform the guiding work. Specifically, the guide block 4 is polished to ensure that the surface of the guide block 4 is smooth.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
