Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical processing technology, specifically a low-cost, rapid edge-cutting device for circular covers. Background Technology
[0002] Aramid composite materials are hailed as the diamond in the crown of global materials science, ranking among the three major high-performance materials. Their industrialization process has a crucial impact on my country's national defense construction and leading industrial projects (such as large aircraft, high-speed trains, shipbuilding, power, electronics and information, and building materials). In the military industry, aramid composite materials are widely used in high-performance structural components and special electronic equipment for aircraft, ships, submarines, tanks, missiles, and radar. In the civilian sector, they are mainly used in high-performance structural components for aerospace, aviation, high-speed trains, and automobiles; high-end insulation materials for large motors and transformers in rail transit, nuclear power, hydropower, and power grid projects; high-performance thermal insulation and flame-retardant materials for building construction; high-end circuit boards and printing; and medical materials.
[0003] However, aramid composite materials are prone to rough edges when cut. In the current technology, handheld power tools are generally used for cutting, which takes 10 minutes to complete and has poor precision. Milling and turning machines take about 5 minutes to process and have more burrs on the edges. In conventional equipment, a milling and turning machine with matching specifications needs to be selected for burr cutting of such products. The equipment costs more than 100,000 yuan, which is expensive. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a low-cost, rapid edge-cutting device for circular covers, which solves the problem of rough edges when cutting aramid composite materials. It uses high-speed grinding to cut the product, resulting in neat, burr-free edges.

[0009] The cylinder includes a cylinder body and a piston rod. The piston rod can move up and down along the cylinder body. The top of the pressure plate is sleeved on the piston rod and connected to the piston rod through a bearing. The bearing allows the pressure plate to rotate on the piston rod along the axial direction.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] In one embodiment of this application:
[0023] like Figures 1 to 2 As shown, a low-cost circular cover quick edge cutting device includes a bracket 3 and a pressure plate 4 for clamping a blank 2. Both the bracket 3 and the pressure plate 4 are rotatable. A cutting machine 5 is provided on one side of the bracket 3. The cutting machine 5 is an electric cutting machine, and the position of the cutting blade on the cutting machine 5 corresponds to the position of the blank 2.
[0024] It also includes a base 1, on which a bracket support platform 31 is provided, and the bottom of the bracket 3 is movably connected to the bracket support platform 31.
[0025] The base 1 is also equipped with a slide table 51, which is a precision hand slide table with a slide rail. The bottom of the cutting machine 5 is slidably connected to the slide rail.
[0026] A bracket 41 is also provided on the base 1, the cylinder is connected to the bracket 41, and the pressure plate 4 is connected to the cylinder.
[0027] The cylinder includes a cylinder body and a piston rod. The piston rod can move up and down along the cylinder body. The top of the pressure plate 4 is sleeved on the piston rod and connected to the piston rod through a bearing. The bearing allows the pressure plate 4 to rotate along the axial direction on the piston rod. During operation, the blank 2 is first placed on the bracket 3 (the blank 2 is a round cover blank made of aramid composite material). Then, the piston rod of the cylinder moves the pressure plate 4 downward to press down the blank 2. Since the top of the pressure plate 4 is connected to the piston rod through a bearing, and the bottom of the bracket 3 is movably connected to the bracket support platform 31, the blank 2, bracket 3, and pressure plate 4 can all rotate freely. The cutting machine 5 is turned on, and the cutting machine 5 is pushed manually to slowly approach the blank 2 from a distance. At the same time, the blank 2, bracket 3, and pressure plate 4 are rotated manually. When the blank 2 comes into contact with the cutting blade of the cutting machine 5, the blank 2 is rotated more than one revolution for each time the cutting machine 5 is pushed closer. The above two steps are repeated until the burrs of the blank 2 are completely removed by the cutting blade. The cutting machine 5 is turned off, and the cutting machine 5 is manually pulled back to the initial position. The cutting work is completed. The cutting time is about 2 minutes, and the cutting repeatability accuracy can reach ±0.1mm.
[0028] In another embodiment of this application:
[0029] Based on the previous embodiment, this embodiment improves the cutting machine 5. A shim can be provided at the bottom of the cutting machine 5. The alignment of the cutting position can be adjusted by adding or removing shims at the bottom of the cutting machine 5, or by adding or removing shims at the bottom of the slide table 51.
[0030] The cutting machine 5 is equipped with a handle for easy pushing and pulling.
[0031] The above description is merely an embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
