Description

Steel ball blank transfer mechanism for steel ball hot stamping forming machine

Technical Field

The utility model belongs to the technical field of the steel ball processing, concretely relates to steel ball base transfer mechanism that steel ball hot stamping forming machine used.

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 a steel round bar to about 1100 ℃ by a heating furnace, discharging the bar material from the furnace, balling the bar material by a steel ball forming device (namely a steel ball balling mechanism), introducing the ball material into a quenching device for quenching after balling, introducing the quenching device such as CN100497666C (a steel ball quenching machine) and CN100497667C (a quenching mechanism of the steel ball quenching machine) into a tempering furnace for tempering after quenching is finished, and discharging the ball material out of the tempering furnace to obtain a finished steel ball.

The balling form of the steel ball forming device mainly comprises the following two types: one is roll forming (i.e. hot roll forming); and the second step is press forming (i.e. 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 rolling forming device has relatively small volume, but has poor adaptability to steel balls with large diameters, namely is suitable for rolling small-specification steel balls; the hot stamping forming device is relatively large in size, but has the advantage of good adaptability to large-size steel balls.

The common operation of holding the cut steel ball blank, which is delivered by the steel ball blank delivery device, into the forming die of the press forming machine by a tool such as a gripper held by an operator is disadvantageous in that: the operation intensity of the operator is high; the operation risk coefficient is high, and the safety is poor; can not be adapted to the high-efficiency production mode which is more and more pursued by people in modern times.

In the steel ball production process, the steel ball blank is transferred from the steel ball blank receiving station to a standby station (namely a transfer station) in a relay mode, and the steel ball blank which is in the standby station is transferred to a balling station (namely a steel ball hot stamping forming machine), and the mode is a high-efficiency production mode.

When the upper die holder 15 moves down together with the upper die 16, the upper die holder 15 drives the sliding platform repelling supporting plate 89 of the structural system of the steel ball blank front supporting mechanism 8 to move down, the sliding platform repelling finger 891 at the lower end of the sliding platform repelling supporting plate 89 enters between the opposite ends of the left and right sliding platforms 81 and 82 of the clamp, the front side of the sliding platform exclusion finger 891 makes contact with a pair of sliding platform exclusion strut left guide rollers 8112 and a pair of sliding platform exclusion strut right guide rollers 8212 as described above by the applicant, the rear side surface of the sliding platform repulsion finger 891 is in contact with one of the pair of sliding platform repulsion supporting plate left guide rollers 8112 and the pair of sliding platform repulsion supporting plate right guide rollers 8212, and the left and right side surfaces of the sliding platform repulsion finger 891 are in contact with the clamp left and right sliding platform rollers 8111, 8211 respectively.

When the slide platform repelling support plate 89 repels the clamp left and right slide platforms 81 and 82, the steel ball blank left supporting jaw driving acting cylinder 85 and the steel ball blank right supporting jaw driving acting cylinder 86 work simultaneously, specifically: the steel ball blank left supporting clamping jaw driving acting cylinder column 851 of the steel ball blank left supporting clamping jaw driving acting cylinder 85 extends towards the outside of the cylinder body, namely towards the right, drives the steel ball blank left supporting clamping jaw 87 to rotate for an angle by taking the left supporting clamping jaw rotating shaft 872 as a rotating center, the free end of the steel ball blank left supporting clamping jaw 87 moves towards the direction departing from the lower die 18, meanwhile, the steel ball blank right supporting clamping jaw driving action cylinder column 861 of the steel ball blank right supporting clamping jaw driving action cylinder 86 extends towards the outside of the cylinder body, namely leftwards, drives the steel ball blank right supporting clamping jaw 88 to rotate for an angle by taking the right supporting clamping jaw rotating shaft 882 as a rotation center, the free end of the steel ball blank right supporting clamping jaw 88 moves away from the direction of the lower die 18, that is, the free ends of the left and right holding jaws 87, 88 of the steel ball blank are repelled to release the holding of the steel ball blank 10 in the lower die 18, and the steel ball blank in the lower die 18 is pressed into a steel ball by the cooperation of the upper and lower dies 16, 18. When the upper die 16 and the sliding platform repelling opening plate 89 are driven to move upwards by the upper die base 15, the steel ball in the lower die 18 is ejected out of the lower die 18 by a forming steel ball ejecting mechanism 9 to be described below, when the sliding platform repelling opening plate 89 moves upwards, the sliding platform repelling finger 891 at the lower end leaves from contact with the left and right sliding platform rollers 8111 and 8211 of the clamp, the left sliding platform repelling opening plate guide roller 8112 of the pair of sliding platforms and the right sliding platform repelling plate guide roller 8212 of the pair of sliding platforms, and at the moment, under the combined action of the left and right sliding platform resetting devices 83 and 84 of the clamp, the left and right sliding platforms 81 and 82 are enabled to move towards each other. At the same time, the left and right supporting clamping jaws of the steel ball blank drive the acting cylinders 85, 86 to work reversely, the steel ball blank 10 transferred from the steel ball blank transfer mechanism assembly 7 to the lower die 18 is supported (clamped) by the opposite folding of the free ends of the left and right supporting clamping jaws 87, 88 of the steel ball blank according to the reverse form, the punching and forming machine 1 acts again, and the process is repeated.

Since the structures and operation principles of the left and right jig slide table returning devices 83 and 84 are the same, the applicant has described only the former: when the sliding platform repulsion supporting plate 89 moves down along with the upper die holder 15 and the sliding platform repulsion finger 891 enters between the left and right sliding platform rollers 8111, 8211 of the clamp, because the left sliding platform 81 of the clamp slides leftwards along the platform guide rail 1321 through the left sliding platform sliding block 813 of the clamp below the left sliding platform, the left guide rod 832 of the structural system of the left sliding platform resetting device 83 of the clamp fixed with the left sliding platform guide rod fixing seat 812 of the clamp moves leftwards (slides) along the left guide rod sliding hole 8311 arranged on the left guide rod seat 831, and the left sliding platform resetting spring 833 of the clamp compresses to store energy. When the sliding platform repelling supporting plate 89 moves upwards along with the upper die base 15 and moves back from between the left and right sliding platform rollers 8111 and 8211 of the clamp, the left sliding platform guide rod fixing seat 812 of the clamp is pushed under the action of the restoring force of the left sliding platform return spring 833 of the clamp, so that the left sliding platform 81 of the clamp is restored to move rightwards.

In this embodiment, the aforesaid left supporting jaw driving cylinder 85 and right supporting jaw driving cylinder 86 for the steel ball blank are air cylinders, but do not exclude the use of oil cylinders.

Referring to fig. 6, the formed steel ball ejecting mechanism 9 includes a steel ball blank ejecting cylinder base 91, a steel ball blank ejecting cylinder 92 and a ball-driving head 93, the steel ball blank ejecting cylinder base 91 is welded or fixed to one of the punch stands 141 on the front left side by a fastener such as a bolt, the steel ball blank ejecting cylinder 92 is fixed to the steel ball blank ejecting cylinder base 91 in an inclined state (inclined toward the lower die 18), a steel ball blank ejecting cylinder column 921 of the steel ball blank ejecting cylinder 92 faces the lower die 18 and corresponds to the upper side of the lower die 18, and the ball-driving head 93 is fixed to the end of the steel ball blank ejecting cylinder column 921.

After the steel ball blank is press-formed into a steel ball by the cooperation of the upper and lower dies 16 and 18, when the upper die is moved upward, the steel ball blank ejecting cylinder 92 operates, the steel ball blank ejecting cylinder column 921 extends outward of the cylinder body, the steel ball is ejected from the lower die by the ball ejecting head 93 fixed to the end of the steel ball blank ejecting cylinder column 921, and the steel ball is drawn out to the next process, such as a quenching process, by the steel ball lead-out groove 20 provided on the right side of the lower die 18 as shown in the drawing. After the ball-by-ball is completed, the ball-by-ball acting cylinder 92 of the steel ball blank works reversely, and the steel ball blank ejecting acting cylinder column 921 retracts to be in the next ball-by-ball standby state.

In the present embodiment, the above-described ball blank ejecting cylinder 92 is an air cylinder, but an oil cylinder may be used.

The applicant can understand from the above description that: the steel ball blank conveying device mentioned above conveys the steel ball blank cut into the cylindrical shape of the blank to the steel ball blank receiving seat 36 (rolling to the steel ball blank receiving seat 36 in a natural rolling manner), the push rod drives the acting cylinder 38 (air cylinder) to work, the push rod 381 pushes the steel ball blank 10 in the horizontal position (horizontal position) on the steel ball blank receiving seat 36 to the steel ball blank receiving sleeve 341 with the sleeve opening facing to the left, and the steel ball blank 10 is in the longitudinal upright state under the clockwise rotation of the steel ball blank receiving rotary seat driving shaft 33 by 90 degrees.

The process that the steel ball blank 10 reaches the lower die 18 from the steel ball blank receiving sleeve 341 is completed by the steel ball blank transfer mechanism assembly 7, and in the process that the steel ball blank transfer mechanism assembly 7 transfers the steel ball blank in a relay manner, the movable beam 6 sequentially moves upwards, rightwards and downwards under the coordination (namely assistance) of the movable beam main driving mechanism 4 and the movable beam auxiliary driving mechanism 5 (the action principle is explained above and is not described again). Specifically, when two steel ball blank transfer mechanism assemblies 7 are at the positions corresponding to the steel ball blank receiving turnover mechanism 3 and the steel ball blank transfer mechanism 2 respectively and clamp the steel ball blanks 10, the moving beam 6 moves upward to move the steel ball blanks 10 in the clamped state upward away (out) of the steel ball blank receiving sleeve 341 and the steel ball blank transfer sleeve 24 respectively, then the moving beam 6 moves rightward to make two steel ball blanks 10 in the clamped state by the two steel ball blank transfer mechanism assemblies 7 correspond to the positions above the steel ball blank transfer sleeve 24 and the lower die 18 respectively, then the moving beam 6 moves downward, and the two steel ball blank transfer mechanism assemblies 7 release the steel ball blanks 10 in the clamped state previously to make the two steel ball blanks 10 enter the steel ball blank transfer sleeve 24 and the lower die 18 respectively. And then moving the cross beam 6 to the left to enable the two steel ball blank transfer mechanism assemblies 7 to respectively correspond to the steel ball blank receiving turnover mechanism 3 and the steel ball blank transfer mechanism 2, and repeating the processes.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
