Description

Technical Field

[0001] This utility model relates to the field of strip workpiece processing equipment, and in particular to a multi-station strip workpiece wire drawing and deburring equipment. Background Technology

[0002] During the production and processing of strip-shaped workpieces, it is necessary to deburr the surface of the workpieces.

[0003] Traditionally, burrs are removed manually by operating milling cutters or by using tools such as files and sandpaper. While this can meet basic needs, it is inefficient and makes it difficult to guarantee the consistency of the finished product.

[0004] Currently, deburring equipment capable of automatically grinding and deburring strip-shaped workpieces is available. This method of deburring the surface of strip-shaped workpieces via a grinding mechanism is widely used in the market. The grinding mechanism consists of an electric grinding head and a linear module. The electric grinding head is mounted on a slide table of the linear module and moves accordingly. The strip-shaped workpiece is positioned by a clamp, and the electric grinding head moves closer to or further away from the workpiece via the movement of the linear module. The grinding wheel of the electric grinding head is driven to rotate by a motor, thus grinding and deburring the surface of the strip-shaped workpiece. Simultaneously, a person pushes or pulls the strip-shaped workpiece to ensure it is ground along its length.

[0005] Existing grinding mechanisms require manual rotation of the strip-shaped workpiece to grind and deburr all four sides, resulting in room for improvement in automation and deburring efficiency. Furthermore, these mechanisms cannot deburr the beveled surfaces of trapezoidal strip-shaped workpieces, limiting their applicability. Therefore, a deburring device is needed that improves deburring efficiency, automation, and expands its applicability. Utility Model Content

The industrial control computer 13, through the infrared sensor and the PLC control program, controls the left side grinding mechanism 4. When the strip-shaped workpiece 9 passes through the left side grinding mechanism 4, the third horizontal linear module 43 of the left side grinding mechanism 4 drives the second electric grinding head 41 to press against the left side of the strip-shaped workpiece 9, and the fourth horizontal linear module 44 drives the second pressing roller 42 to press against the right side of the strip-shaped workpiece 9. The first electric grinding head 41 rotates and grinds the left side of the strip-shaped workpiece 9 to remove burrs. The industrial control computer 13 controls the lower surface grinding mechanism 5 through infrared sensors and PLC control program. When the strip-shaped workpiece 9 passes through the lower surface grinding mechanism 5, the first worm gear jack 14 mechanism of the lower surface grinding mechanism 5 drives the third electric grinding head 51 to press against the lower surface of the strip-shaped workpiece 9. Then the grinding wheel of the third electric grinding head 51 rotates and grinds the lower surface of the strip-shaped workpiece 9 to remove burrs. The industrial control computer 13 controls the upper surface grinding mechanism 6 through infrared sensors and PLC control program. When the strip-shaped workpiece 9 passes through the upper surface grinding mechanism 6, the second worm gear jack 14 mechanism of the upper surface grinding mechanism 6 drives the fourth electric grinding head 61 to press against the upper surface of the strip-shaped workpiece 9. Then the grinding wheel of the fourth electric grinding head 61 rotates and grinds the upper surface of the strip-shaped workpiece 9 to remove burrs.

[0047] The implementation principle of a multi-station strip workpiece wire drawing and deburring device according to an embodiment of this application is as follows: The worker pushes the strip-shaped workpiece 9 from the loading platform 7 onto the conveyor belt 12 of the machine cover 11 and passes through the first limiting roller 15, the second limiting roller 15, and the third limiting roller 15. Under the continuous conveying of the conveyor belt 12, the strip-shaped workpiece 9 passes through the right side grinding mechanism 3, the left side grinding mechanism 4, the lower surface grinding mechanism 5, and the upper surface grinding mechanism 6 in sequence. All four sides of the strip-shaped workpiece 9 are simultaneously ground and deburred. Then, the conveyor belt 12 at the upper surface grinding mechanism 6 transports the strip-shaped workpiece 9 to the unloading platform 8, which not only improves the deburring efficiency but also the deburring accuracy.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
