Drum adjustable ball forming device of steel ball rolling machine

Abstract

The invention relates to a drum adjustable ball forming device of a steel ball rolling machine and belongs to the technical field of steel ball machining machinery. The drum adjustable ball forming device comprises a supporting frame, a pair of drum mechanisms, a pair of drum inclination angle adjusting mechanisms, a pair of ball forming roller pivotal supporting frame adjusting mechanisms, a lower ball baffle and an upper ball baffle. The supporting frame is provided with a front side pillar, a rear side pillar, a front beam, a rear beam and a pair of supporting frame connection seat plates. A pair of top limitation mechanisms of a front bearing seat and a rear bearing seat are arranged on the front beam and the rear beam. Ball forming roller pivotal supporting frames are connected to the drum mechanisms. Ball forming rollers are arranged on the ball forming roller pivotal supporting frames. The drum inclination angle adjusting mechanisms are connected with the drum mechanisms. The ball forming roller pivotal supporting frame adjusting mechanisms are connected with the ball forming roller pivotal supporting frames. The lower ball baffle is arranged on the lower portion of the supporting frame and the upper ball baffle is arranged between the front beam and the rear beam. Each drum mechanism comprises a drum seat, a drum and a poking rod. The middle transitional links are reduced, operation is capable of saving labor, and the drum adjusting efficiency is improved. A drum support positioning plate is removed and the poking rod is not subjected to abrasion. When the drum is adjusted, the blindness can be avoided, adjustment precision is ensured, the drum adjustable ball forming device is convenient to manufacture and assemble and materials are saved.

Description

Technical field [0001] The invention belongs to the technical field of steel ball processing machinery, and in particular relates to an adjustable ball forming device of a rotating drum of a steel ball mill. Background technique [0002] Steel balls are the medium used by ball milling equipment to grind materials. Taking the building materials industry such as cement manufacturers as an example, in the process of producing cement, it is necessary to ball mill the ore that has been crushed by the previous process (crusher crusher) (the industry is customarily called grinding ), and ball milling requires a large amount of steel balls with ideal wear resistance and excellent hardness. The production process of the steel ball is: the bar (steel round bar) is heated to about 1100℃ by a heating furnace, and after being discharged from the furnace, the ball forming device of the ball rolling machine is rolled into a ball, and the steel ball is introduced after the ball is formed Quench...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned CN100471597C disclosed the enlightenment of adjusting the inclination angle of the ball forming roller by adjusting the inclination angle of the drum, but there are the following shortcomings: one is because the adjustment of the inclination angle of the drum is through the operation of the drum adjustment screw, and the adjustment screw is adjusted by the drum. Drive the drum positioning plate connected with the drum screw to move back and forth, and then realize the effect of the front and rear movement of the drum positioning plate on the screws fixed on the drum

Therefore, there are many transition links, the operation is laborious and the adjustment speed is affected; secondly, due to the severe friction between the top end face of the drum positioning plate and the end face of the aforementioned screw fixed on the drum during the adjustment process, wear is particularly prone to occur. Therefore, when there is wear between the two, the top end surface of the drum positioning plate cannot be in contact with the screw, resulting in failure to adjust the drum, that is, the drum cannot obtain the desired adjustment effect, and the final disadvantage of drum adjustment failure is Factors lead to the inclination angle of the ball forming roller cannot be formed; thirdly, because the adjustment degree of the drum is judged entirely by the operator's experience, there is no reasonable scientific basis for judgment, and because the judgment on the degree of inclination adjustment will vary depending on the operator's Due to differences in responsibility, experience, and even emotional changes, it is often difficult to obtain the expected scissors-edge effect for a pair of ball forming rollers; Fourth, due to the complex structure of the entire drum mechanism, for example, it is necessary to equip The bottom plate of the drum seat is fixed on the bottom of the bracket by the bottom plate of the drum seat and the drum seat, so not only the production and assembly are cumbersome, but also the raw and auxiliary materials for making the drum mechanism are wasted
