Description

Quick change feed wheel device Technical Field The utility model relates to the technical field of manufacturing of cold heading machines, in particular to a feeding wheel device capable of being quickly replaced. Background The cold header is forging forming equipment for thickening the top of a bar or a wire rod at room temperature, and is special equipment mainly used for mass production of fasteners such as nuts and bolts. Specifically, the cold header drives curled steel into a machine body of the cold header through a feeding mechanism, shears the curled steel into a plurality of sections through a shearing mechanism, and the steel sections are subjected to upsetting through a upsetting mechanism and are subjected to working procedures such as forming, chamfering, thread rolling, diameter reduction, trimming and the like, so that products such as screws, bolts and the like are processed. In the feeding mechanism, steel materials with different wire diameters need to be matched with feeding wheels with different sizes to be hard extruded, and for steel materials with thick wire diameters, larger feeding wheels are needed to roll, and the dead weight of the feeding wheels is heavier. The need to lift the heavy feed wheel to a high position during loading and unloading of the feed wheel, especially on large machines, becomes a laborious and cumbersome task. There is also a possibility that the feeding wheel slips down during handling operations of the feeding wheel, which may cause injury to the operator. The quick change feeding wheel device is developed for the purpose of preventing the feeding roller from falling and simultaneously facilitating the loading and unloading of the feeding wheel. Disclosure of Invention The utility model aims to provide a quick-change feeding wheel device so as to solve the problems in the background technology. The quick change feeding wheel device is applied to a cold header and comprises a crane hook, and is characterized in that a feeding wheel frame is hung below the crane hook, a feeding wheel fixing seat for transferring feeding wheels is fixed on the feeding wheel frame, a locating shaft for locating the whole quick change feeding wheel device in a preset mode is arranged on the feeding wheel fixing seat, a first guide key is arranged on the feeding wheel fixing seat, a locating hole is formed in the feeding wheel fixing seat, a first locating pin for preventing the feeding wheels from shifting is inserted in the locating hole, and a second guide key which is parallel to the first guide key is arranged on the cold header body. Compared with the prior art, the utility model has the advantages that when the feeding wheel is to be replaced, the crane hook is used for inserting the positioning shaft of the whole set of rapid-replacement feeding wheel device into the cold header body, the first guide key and the second guide key are aligned side by side, at the moment, the old feeding wheel can be pushed onto the rapid-replacement feeding wheel device from the cold header body, the positioning shaft is inserted into the positioning hole for fixation by the first positioning pin, and the whole set of device is moved to the ground. And taking out the first locating pin, pushing out the old feeding wheel, pushing in the new feeding wheel, and fixing by using the first locating pin. And (3) lifting the whole device onto the cold header by using a crane hook, taking off the first positioning pin after the positioning shaft and the first guide key are opposite to the corresponding position, and pushing in the new feeding wheel. The novel structure is high in disassembly and assembly efficiency and safe. As an improvement of the utility model, the length of the first guide key is smaller than the width of the feeding wheel. The design is selected for the purpose that due to the arrangement of the first guide key and the second guide key, the inner ring of the feeding wheel is correspondingly provided with a key slot penetrating through the whole thickness of the wheel, so that the guide key can penetrate conveniently. When the old feeding wheel is rotated, the old feeding wheel is required to be connected to the feeding wheel fixing seat of the feeding wheel device which is quickly replaced, and the old feeding wheel is smoothly guided to the feeding wheel fixing seat through the longer second guide key, wherein the feeding wheel fixing seat is also provided with a key groove for placing the first guide key and the second guide key. As an improvement of the utility model, the feeding wheel frame is used for fixing the feeding wheel fixing seat through a second locating pin. The design is selected to firmly fix two parts, namely the feeding wheel fixing seat and the feeding wheel frame. As an improvement of the utility model, the positioning shaft penetrates through the center parts of the feeding wheel fixing seat and the feeding wheel frame and then is fixed by a fixing nut.
