Description

Steel ball radial punching thermal forming device

Technical Field

The invention belongs to the technical field of steel ball processing machinery, and particularly relates to a steel ball radial punching thermoforming device.

Background

The steel balls are also called "grinding balls", which are used as a medium for grinding materials by ball milling equipment in the mineral processing industry, the chemical industry, the building material industry and the like, and take building material industry such as cement manufacturers as an example, in the cement production process, the ore crushed and sieved by a previous process such as a crusher is required to be subjected to ball milling (commonly called "grinding" in the industry), and a large number of steel balls with ideal wear resistance and excellent hardness and toughness are required to be used for ball milling.

The production process of the steel ball is as follows: the bar materials are heated by a heating furnace, are balled by a steel ball forming device, namely a steel ball balling mechanism, are introduced into a quenching device for quenching after being balled, and are introduced into a tempering furnace for tempering after quenching, namely CN100497666C (steel ball quenching machine) and CN100497667C (quenching mechanism of the steel ball quenching machine) for quenching, and are discharged from the tempering furnace for obtaining finished steel balls.

The balling forms of the balling device mainly comprise the following two types: one is roll forming (i.e., hot rolling forming); and secondly, stamping thermoforming (also called hot stamping forming). Typical examples of the former are CN100471597C (forming mechanism of bar ball mill), CN103495685B (ball forming mechanism of rolling mill), CN101934334B (ball forming mechanism of rolling mill), and CN102091750B (ball forming mechanism of rolling mill with ball roller capable of being quickly assembled and disassembled), etc.; typical examples of the latter are CN101844207a (an automatic steel ball casting machine), CN205966823U (a steel ball forming machine), CN167414002a (a large horizontal shearing and feeding integrated steel ball forming machine), and so on. The volume of the device used for rolling forming is relatively small, but the device has poor adaptability to steel balls with large diameters, namely the device is more suitable for rolling small-specification steel balls; the apparatus used for hot press forming is relatively bulky, but has the advantage of good adaptability to large steel balls and is significantly more efficient than the former, so the latter is relatively heavy in the industry.

A more typical example of the above-mentioned stamping thermoforming apparatus is the "steel ball thermoforming apparatus" recommended by CN110026468a, which patent application is built in: the action in the balling process can embody a good relay effect, so the method is very beneficial to improving the productivity. However, the CN110026468a still has the following drawbacks: first, according to the description of paragraph 0028 of the specification, since the hot stamping power source adopts a hydraulic driving structure, the manufacturing cost of the complete set of balling devices is relatively high; secondly, the reliability of the action is difficult to ensure by adopting a hydraulic structure as a power source, and the daily inspection and protection are troublesome; thirdly, the driving precision is low, and the speed is difficult or even impossible to adjust; fourth, there is a concern that oil leaks to contaminate the work site; fifthly, as the mechanisms are scattered and arranged at intervals, the structure is loose, and the occupied space is large. In view of the foregoing, there is a need for reasonable improvements, and the technical solutions described below are created in this context.

The lower end of the gate lever (73) extends downward to the front side corresponding to the end of the heated steel round rod introduction hole (113) facing the frame cavity (111) and between the cutting knife (66). One end of the gate lever cross arm return tension spring (74) is fixed to the upper side of the middle part of the gate lever cross arm (72) through a gate lever cross arm return spring seat (741), and the other end of the gate lever cross arm return tension spring (74) is fixed to the gate lever cross arm. The gate rod return device (75) comprises a gate rod return spring rod first fixed seat I (751), a gate rod return spring rod second fixed seat II (752), a gate rod return spring rod (753) and a gate rod return spring (754). The gate rod return spring rod first fixed seat I (751) is fixed to the top of the gate rod (73). The gate rod return spring rod second fixed seat II (752) is fixed to the upper side of the gate rod cross arm (72) at a position corresponding to the rear of the gate rod cross arm return spring seat (741). The gate rod return spring rod (753) is adjustably connected to the gate rod return spring rod first fixed seat I (751) and the gate rod return spring rod. The gate rod return spring (754) is sleeved on the middle part of the gate rod return spring rod (753) between the spring rod second fixing seat II (752), the rear end of the gate rod return spring (754) is abutted on the gate rod return spring rod first fixing seat I (751), and the front end of the gate rod return spring (754) is abutted on the gate rod return spring rod second fixing seat II (752); the gate rod cross arm lifting block (331) of the gate rod cross arm lifting block (331) corresponds to the middle part of the side of the gate rod cross arm (72) facing downward; a gate rod cross arm anti-side deflection block (116) is fixed on the frame (11) and at a position corresponding to the middle part of the left side of the gate rod cross arm (72).
