Description

Technical Field

[0001] This utility model relates to the field of steel strip processing technology, and in particular to a double-sided chamfering device for steel strip. Background Technology

[0002] In the stainless steel strip processing industry, chamfering the sides is a crucial step. Currently, there is a lack of dedicated chamfering equipment for both sides of stainless steel strips on the market, and most chamfering is done manually. This manual method has significant drawbacks. Firstly, manual grinding is extremely inefficient, making it difficult to meet the needs of large-scale industrial production. Secondly, the stability and consistency of manual operation are poor, resulting in uneven chamfering and unsatisfactory processing results. It can only achieve basic burr removal and cannot meet the aesthetic requirements of chamfering, seriously affecting the overall quality and appearance of the stainless steel strip.

[0003] Furthermore, some companies in the industry use flashing machines to address the issue of stainless steel strip side edge defects. While flashing machines cut away a portion of the material from both sides of the stainless steel strip using blades, which can improve the aesthetics of the strip's sides to some extent, this method results in significant material loss, substantially increasing production costs and contradicting the industrial development trends of green production and cost reduction. Therefore, there is an urgent need to develop a high-efficiency, uniform, and material-reducing double-sided chamfering device for stainless steel strip sides to solve the aforementioned problems in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency double-sided chamfering device for steel strips, addressing the shortcomings and deficiencies of existing technologies.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Furthermore, the chamfering tool assembly consists of two chamfering tools; the two chamfering tools are arranged facing each other.

[0008] Furthermore, the chamfering cutter is shaped like a frustum of a cone; a positioning hole is provided on the axis of the chamfering cutter; the diameter of the positioning hole is equal to the diameter of the inner shaft; the inner shaft is inserted into the positioning hole; a screw is fixed to the end of the inner shaft; a locking nut is threaded onto the screw; the locking nut presses the two chamfering cutters tightly onto the end face of the inner shaft.

[0009] Furthermore, the screw is fitted with an anti-slip pad; the anti-slip pad is pressed between two chamfering blades.

[0010] Furthermore, the power module includes a column fixed on the slide and a fixing plate fixed on the column; a motor is fixed on the fixing plate; a driving synchronous pulley is fixed at the output end of the motor; a driven synchronous pulley is fixed on the inner shaft; a synchronous belt connects the driven synchronous pulley and the driving synchronous pulley; and the inner shaft is rotatably connected to the fixing plate.

[0011] Furthermore, an outer cylinder is fitted around the inner shaft; the outer cylinder is fixed to a fixed plate; a bearing is provided between the inner shaft and the outer cylinder; the outer ring of the bearing is fixed to the inner wall of the outer cylinder; and the inner ring of the bearing is fixed to the inner shaft.

[0012] Furthermore, it also includes an adjustment mechanism; the adjustment mechanism includes multiple guide rods and fixed seats connected to both ends of the guide rods; each fixed seat has a cylinder fixed on it; the piston rods of the two cylinders are respectively fixed on a slide block; a guide sleeve matching the guide rod is fixed on the slide block; the guide rod is inserted into the interior of the guide sleeve.

[0013] With the above structure, the beneficial effects of this utility model are as follows: the power modules on both sides drive the inner shafts on both sides to rotate, so that the chamfering blades on both sides rotate synchronously, and can chamfer both sides of the steel strip at the same time; the diameter of the chamfering blades first decreases and then increases, so that a "V" shaped groove structure is formed on the cross-section of the blade, which can chamfer both the upper and lower sides of one edge of the stainless steel strip at the same time; the efficiency of steel strip chamfering is improved, and only the material of the chamfered part needs to be cut out, reducing material loss.
