Meanwhile, in a specific structure, the pressing cylinder 34 is arranged on the mounting frame 33, the pressing plate 35 is connected with the top end of a piston rod of the pressing cylinder 34, the pressing cylinder 34 drives the pressing plate 35 to do linear reciprocating motion along the vertical direction, wherein the pressing plate 35 is located at a preset distance above the sliding table 32, a gap between the pressing plate 35 and the sliding table 32 forms a pressing space for the to-be-cut piece to pass through, the pressing plate 35 is matched with the sliding table 32, and the pressing plate 35 is driven by the pressing cylinder 34 to move downwards or upwards, so that the pressing or loosening of the to-be-cut piece is completed, the structure is simple, and the control operation is convenient.

As shown in fig. 9, the cutting device of the pultrusion device of the utility model has the following use process:

when the section bar product, namely the to-be-cut piece, reaches the required length, the piston rod of the pressing cylinder 34 extends out to drive the pressing plate 35 to press downwards and clamp the product up and down with the sliding table 32. The sliding table 32 moves along the second guide rail 7 following the product, and drives the piston rod of the telescopic cylinder 311 to extend synchronously. In the moving process of the sliding table 32, the cutting motor 38 is started to drive the cutting blade 39 to rotate, when the cutting motor 38 reaches the required rotating speed, the piston rod of the swing arm cylinder 37 retracts to drive the mounting end 361 of the boosting rod 36 to move upwards, and the cutting motor 38 and the cutting blade 39 move upwards along with the mounting end 361. When the piston rod of the swing arm cylinder 37 is fully retracted, the product can be completely cut off. The piston rod of the swing arm cylinder 37 is then immediately fully extended, at which time the cutting motor 38 stops rotating. Then the piston rod of the pressing cylinder 34 retracts to drive the pressing plate 35 to ascend, the pressing plate 35 does not press the product any more, the sliding table 32 stops moving along with the product, the piston rod of the telescopic cylinder 311 retracts completely, and the sliding table 32 is pulled to return to the original point along the second guide rail 7. So far, the whole cutting process of the product is completely finished.

The utility model discloses a cutting device among pultrusion equipment, wherein, the swing of cutting motor 38 drives the power boost pole 36 through swing arm cylinder 37 and swings around support 310 and realize, and cutting device complete machine structure requires relatively lowly to the machining precision of installation requirement and part. In many dust environment, because of using in the cutting device to pivot swing structure, the dust is difficult for getting into in the cutting device to greatly reduced appears the cutting device card and dies or the probability of the card phenomenon of pause. And simultaneously, the utility model discloses a cutting device among the pultrusion equipment also can shorten the cutting time through the flexible speed that improves swing arm cylinder 37, makes cutting device adaptable faster product production speed in the 7 length spaces of the same second guide rail.

This cutting device drives the power boost pole through the swing arm cylinder and swings around the support, realizes then that the cutting assembly is close to and cuts and treats the piece or keep away from and treat the piece to accomplish the cutting process, complete machine simple structure requires lowly to installation requirement and parts machining precision. Because of adopting the structure of swinging around the axle in many dust environment, the dust is difficult for getting into the cutting machine, reduces the cutting machine and appears the production of card dead or the card pause phenomenon to and reduce many dust environment to the influence in the cutting machine use. Adopt the structure of swing arm cylinder cooperation force-increasing pole simultaneously, the adverse effect that greatly reduced atmospheric pressure is unstable to equipment production, cooperation cutting assembly improves cutting efficiency greatly.
