The specific embodiment

As illustrated in fig. 1 and 2, scraper type burr grinding machine comprises push unit 1, Traverse Displacement Unit 2, lowering or hoisting gear 3, axletree track-type facilities 4, traversing cylinder 5, buffer 6, lift cylinder 7, cutter 8, rack-and-pinion 9 and triangle lifter plate 10 at least, and Traverse Displacement Unit 2 two ends are connected with buffer 6 with the traversing cylinder 5 of push unit 1; One the first from left right rack-and-pinion 9 by axletree track-type facilities 4 lower ends in lower end is connected with the pedestal of push unit 1, pass Traverse Displacement Unit 2 by traversing cylinder 5 and move forward and backward along the tooth bar in the rack-and-pinion 9, the cutter 8 that drives when Traverse Displacement Unit 2 moves forward and backward on the tool rest moves removal strand burr; There is lift cylinder 7 at Traverse Displacement Unit 2 two ends, and lift cylinder 7 connects lowering or hoisting gear 3 by triangle lifter plate 10, and lowering or hoisting gear 3 is supporting cutter 8, and lift cylinder 7, triangle lifter plate 10 and cutter 8 integral installations are in the framework of Traverse Displacement Unit 2; Axletree track-type facilities 4 supports Traverse Displacement Unit 2.

As shown in Figure 2, traversing cylinder 5 and the buffer 6 installed on 1 liang of bearing of push unit are done positive and negative motion to reach the purpose of removing burr by the flexible drive Traverse Displacement Unit 2 of cylinder; Traverse Displacement Unit 2 drives lowering or hoisting gear 3 and cutter 8 edge casting flow path direction back and forth movements, to remove the front and back end burr; Lowering or hoisting gear 3 is mainly used in the tool rest of supporting cutter 8 and it is moved up and down, and makes cutter 8 rise and touch the strand lower surface with certain pressure burr is removed; 4 of axletree track-type facilities mainly are to support Traverse Displacement Unit 2 it is moved back and forth along fixing guide rail.

Well contact in order to make cutter 8 not influence cutter 8 because of strand is uneven with the strand contact-making surface, cutter 2 groups of front and back dislocation in 8 fens arrange that its width is decided on the strand width.Cutter 8 adopts the oblique installation that becomes 5.6 ° of angles with axis, every group of cutter 8 lower ends all are furnished with the dish spring, to adapt to the bulge deformation of strand, therefore cutter 8 rises and can be close to the strand lower surface with certain pressure, and power source is driven by pneumatic linear actuator, speed is fast, and scraping power is big, can be with burr scraped clean up hill and dale rapidly.The traversing speed and the rate of climb of cutter can be adjusted in certain OK range by the flow speed control valve in the pneumatic means.Because cutter 8 adopts the oblique installation that becomes 5.6 ° of angles with axis, the shearing resistance when having reduced deburring.The deburring stroke is by the stroke and the travel switch control of traversing cylinder.Adopt mechanical type rack-and-pinion 9 forced synchronism in mechanism, Traverse Displacement Unit is moved back and forth along fixing guide rail, in order to prevent Traverse Displacement Unit 2 in walking time-frame frame come-up, lowering or hoisting gear 3 is connected with guide plate 11, is led by guide plate 11.In the deburring process, move in order to prevent strand.Flash trimmer all is provided with forward and backward two groups of hold-down mechanisms.Whole deburring mechanism is reasonable in design, arranges compactness, coordination, and the whole automations of whole deburring process are finished.

Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D, Fig. 3 E, Fig. 3 F, Fig. 3 G, Fig. 3 H, Fig. 3 I, Fig. 3 J, Fig. 3 are respectively the different step key diagrams of deburring process.

Be the explanation of deburring process different step below:

Fig. 3 A is that cutter is parked in front end deburring position, and after the front end strand compressed, water spray cooled off for 3 seconds;

Fig. 3 B is that cutter rises, and finishes the action of front end strand deburring for the first time after 3 seconds;

Fig. 3 C cutter descends and returns;

Fig. 3 D cutter rises, and finishes the action of front end strand deburring for the second time after 3 seconds;

Fig. 3 E cutter descends, and is parked in deburring position, strand rear end;

Fig. 3 F rear end hold down gag compresses strand, simultaneously 3 seconds of water spray cooling strand rear end burr;

Fig. 3 G cutter rises, and finishes rear end strand deburring action for the first time after 3 seconds;

Fig. 3 H cutter descends and turns back to deburring position, strand rear end;

Fig. 3 I cutter rises, and finishes rear end strand deburring action for the second time after 3 seconds;

Fig. 3 J cutter descends, and the rear end hold down gag is raised to position of readiness, and strand transports;

Fig. 3 K slab leaves equipment after 3 seconds, and cutter was cooled off for 5 seconds, waits for next block casting base.

When removing the front end burr, when strand after front position stops on the roller-way, the front end hold-down mechanism of hold down gag just can be pressed to strand, after the front end burr is removed, and the front end hold-down mechanism is when lifting, roller-way could start transports base; When removing the rear end burr, when strand after back-end location stops on the roller-way, the rear end hold-down mechanism of hold down gag just can be pressed to strand, after the rear end burr is removed, and the rear end hold-down mechanism is when lifting, roller-way could start transports base.
