Description
Technical Field
The utility model belongs to the technical field of steel ball processing machinery, concretely relates to steel pole marching type feeding mechanism of radial hot stamping ball-forming machine.
Background
The steel balls are also called "grinding balls", which are media for grinding materials by ball-milling equipment used in mineral processing industry, chemical industry, building material industry and the like, and taking building material industry such as cement manufacturers as an example, in the process of producing cement, the ball milling (which is conventionally called "grinding" in industry) needs to be carried out on ores crushed and screened by a crusher in a previous process, and the ball milling needs to use a large amount of steel balls with ideal wear resistance and excellent hardness and toughness.
The production process of the steel ball comprises the following steps: heating a bar material such as the steel round bar by a heating furnace, discharging, balling by a steel ball forming device, namely a steel ball balling mechanism, introducing into a quenching device for quenching after balling, introducing into a tempering furnace for tempering after quenching by the quenching device such as CN100497666C (steel ball quenching machine) and CN100497667C (quenching mechanism of the steel ball quenching machine), and discharging from the tempering furnace to obtain a finished steel ball.
The balling forms of the balling device mainly include the following two types: one is roll forming (i.e. hot roll forming); the second is press thermoforming (also referred to as "hot press forming"). Typical examples of the former include CN100471597C (forming mechanism of bar mill), CN103495685B (balling device of ball mill), CN101934334B (balling mechanism of ball mill), and CN102091750B (balling mechanism of ball mill with rapidly detachable ball rolls), etc.; typical examples of the latter are CN101844207A (an automatic steel ball casting and forming machine), CN205966823U (a steel ball forming machine), and CN167414002A (a large horizontal shearing and feeding integrated steel ball forming machine), etc. The device used for rolling and forming is relatively small in size, but has poor adaptability to steel balls with large diameters, namely the device is suitable for rolling steel balls with small specifications; the device for hot press forming is relatively large in size, but has the advantages of good adaptability to large-size steel balls and remarkably higher efficiency than the former, so that the latter is heavier in the industry.
A more typical example of the above-mentioned stamping hot forming device is a "steel ball hot forming device" recommended by CN110026468A, which is built by the following steps: the action in the balling process can show good relay effect, so the method is very beneficial to improving the productivity. However, the aforesaid CN110026468A still has the following disadvantages: the steel ball blank is more from the steel ball blank receiving turnover mechanism to the upper die and the lower die, specifically, a separately equipped device cuts a steel round bar which is heated by a heating furnace into steel ball blanks and sends the steel ball blanks to the steel ball blank receiving turnover mechanism of the structure system of the patent, the steel ball blank receiving turnover mechanism receives the steel ball blanks and turns the steel ball blanks 90 degrees from the previous horizontal state to be in a vertical state, then the steel ball blanks are clamped by a steel ball blank relay transfer mechanism arranged on a moving beam, a moving beam main driving mechanism drives the moving beam to move, the moving beam drives the steel ball blank relay transfer mechanism and the steel ball blanks to correspond to a station where the steel ball blank transfer mechanism is arranged, the clamped steel ball blanks are placed in a steel ball blank release transfer mechanism, and simultaneously, another steel ball blank relay transfer mechanism arranged on the moving beam clamps the steel ball blanks which are previously positioned at the steel ball blank transfer mechanism station and releases the steel ball blanks into the lower die, under the clamping of the steel ball blank front clamping mechanism, the upper die base is driven by the hydraulically-driven upper die driving mechanism described in paragraph 0028 of the specification, and the upper die mounted on the upper die base is hot-stamped to form the steel ball for the steel ball blank positioned in the lower die, so that the process from the introduction of the steel ball blank to the hot-stamping to form the steel ball is relatively long, the structure is complex due to a plurality of process links, the manufacturing cost is high, the action reliability is low, the overall structure is loose, the space occupation is increased, and the efficiency of feeding the steel ball blank to the lower die is not enough to achieve the expectation of the industry. In view of the foregoing, it is desirable to improve upon the technical solutions described below.
