Description

Technical Field

[0001] The present application relates to the technical field of metal processing equipment, and in particular to a bracket burr removal machine. Background Art

[0002] Computer bracket bar hardware usually has burrs after demolding through mold production, which requires subsequent grinding and removal.

[0003] In this regard, China's patent application number CN202122587627.X discloses a burr removal machine for computer stand hardware. This solution places the computer stand hardware on the mounting boss to keep the cross-sectional shapes overlapped with each other, and then presses the upper pressure plate toward the base. Since the lower end surface of the shearing head is provided with a groove matching the cross-sectional area of ​​the mounting boss; therefore, when the mounting boss together with the hardware is pressed into the groove, the shearing head can shear and remove the excess burrs on the edge of the hardware.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] The computer stand needs to be held by hand, which requires very high smoothness of the edges. Shearing to remove burrs cannot improve the sharp edges, and they still need to be rounded later, so the processing efficiency is not high. Utility Model Content

[0006] In order to make up for the above shortcomings, the present application provides a bracket burr removal machine, which aims to improve the problems mentioned in the above background technology.

[0007] An embodiment of the present application provides a bracket burr removal machine, including a machine table, on which a clamp and a blowing member are arranged, a mold is clamped in the clamp, a computer bracket body is placed on the mold, a grinding groove adapted to the edge contour of the computer bracket body is opened on the mold, abrasive is arranged in the grinding groove, and the blowing member blows the abrasive to move.

[0008] In a specific embodiment, a groove matched with the computer stand body is formed on the mold, and a pressure rod is rotatably connected to the mold, and the pressure rod is movably pressed against the computer stand body.

[0009] In the above implementation process, the computer stand body is directly placed into the groove to play a positioning role. At this time, the grinding groove is closed, and the pressure rod is rotated and pressed onto the computer stand body to prevent the computer stand body from being lifted up by the air pressure in the grinding groove.

[0010] In a specific embodiment, the fixture includes a support and a spinning cylinder, the mold is plugged into the support, and the spinning cylinder is movably pressed against the mold.

[0011] In the above implementation process, the mold is placed on the machine table and then inserted into the support. Two spinning cylinders hold the mold against the mold to complete the installation and fixation of the mold. This clamping method facilitates the replacement of the mold.

[0012] In a specific embodiment, the mold is provided with a pipe opening communicated with the grinding groove, and the support is provided with an interface connected with the pipe opening.

[0013] In the above implementation process, when the mold is inserted into the support, the pipe mouth is also inserted into the interface to complete the connection with the blowing member.

[0014] In a specific implementation manner, the blowing member includes a fan with switchable wind direction, two air outlets of the fan are connected with air ducts, and the air ducts are fixedly connected with the interface.

[0015] In a specific implementation manner, a material storage area is arranged at a position of the air duct close to the blowing member, and a filter is arranged between the material storage area and the air outlet.

[0016] In the above implementation process, the spherical abrasive is located in one of the storage areas, and the fan blows the abrasive into the grinding groove, and the edge of the computer bracket body is polished along the grinding groove, and then enters another storage area. Then the fan reverses, and the abrasive returns to the previous storage area, and this process is repeated. The filter is used to prevent the abrasive from entering the fan. In this embodiment, low-density abrasive is used to facilitate being blown by the wind. It should be noted that since the two ends of the grinding groove need to be connected to the two ports of the fan, the friction is an open-loop structure, which results in a grinding dead corner in the edge of the computer bracket body between the two pipe openings, which needs to be polished separately afterwards.

[0017] In a specific implementation manner, a ejector is further provided below the computer stand body.

[0018] In the above implementation process, the ejector is used to eject the computer stand body out of the mold.

[0019] In a specific embodiment, the ejector includes a cylinder and an ejector block, the cylinder is installed under the machine platform, the ejector block is movably connected to the machine platform, the telescopic end of the cylinder is hinged to the ejector block, and the ejector block movably passes through the mold.

[0020] In the above implementation process, the ejector block is usually retracted in the machine, and a through hole is opened on the mold. When ejection is required, the cylinder pushes the ejector block through the mold to eject the computer bracket body. This arrangement facilitates the loading and unloading of the mold and reduces the mold cost.

[0021] Compared with the prior art, the beneficial effect of the present application is: the edge of the computer stand body is protruded into the grinding groove by using a mold, and the abrasive is blown into the grinding groove by a blowing piece to grind the edge of the computer stand body, which can not only remove burrs, but also has the effect of grinding and polishing, and has a more efficient deburring effect than the shearing type.
