Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing:
[0018] With reference to the accompanying drawings, the hobbing processing device of the scalloped steel strip of the present invention includes a frame 2, a guide roller group 14, a clamping roller group 13, a servo motor I4, a limit guide rail 7, a pressing plate 5, an equidistant Variable tooth height hob 3, servo motor II 11, conveying roller 8, flattening roller group 10, guide roller group 14, clamping roller group 13, conveying roller 8, and flattening roller group 10 are arranged horizontally on the frame in sequence, The pressing plate 5 is placed between the pinch roller group and the flattening roller group, above the conveying roller, and the pressing roller 15 (such as image 3 As shown), the frame of the pressing plate is longitudinally connected with the cylinder 1, and the equidistant variable tooth height hob is installed on the frame on the side of the pre...

The invention relates to a hobbing processing method and a hobbing processing device for a knuckle-tooth steel belt. The processing method comprises the steps that a servo motor I drives a niproll set to allow the steel belt to enter a processing area of an equidistant and tooth-depth-variable hob; a pressing plate clamps the steel belt under the action of air cylinders; the equidistant and tooth-depth-variable hob performs hobbing processing from shallow to deep on the steel belt under driving of a servo motor II; a circular tooth socket is processed for the steel belt under the action of hobbing of the equidistant and tooth-depth-variable hob; and an axial tooth pitch of the equidistant and tooth-depth-variable hob is equal to a tooth pitch of the steel belt. The processing method and the processing device have the advantages that teeth on the knuckle-tooth steel belt are successively engaged with teeth on the equidistant and tooth-depth-variable hob to cut an allowance, so that the device has the advantages of simple structure, low production cost, good processing precision and the like; the production efficiency and the processing quality of the knuckle-tooth steel belt are improved; and a production requirement is met.
Description
technical field [0001] The invention belongs to the technical field of hobbing processing in the machinery industry, and in particular relates to a hobbing processing method and device for a scalloped steel strip. Background technique [0002] Scalloped steel belts can be used in display racks in large supermarkets or warehouses. Two scalloped steel belts separated by a certain distance are arranged equidistantly at the scalloped teeth to match the steel rods. The steel rods and steel belts are welded to form a display rack. . [0003] At present, there are two main processing methods for scalloped steel strips: hot extrusion and cold stamping. If the steel strip is processed by the hot extrusion method, irregular protrusions will appear on the surface of the scalloped teeth of the steel strip, which will affect the aesthetics of the surface; while the steel strip is processed by the cold stamping method, which is an intermittent operation and the processing efficiency is l...
