Description

The novel high speed cutting machine

Technical field

The utility model relates to a kind of disconnected novel high speed cutting machine of cutting metal wire rod that is used for.

Background technology

Existing metal wire rod cutting machine structure is: a blade that cuts off wire rod is arranged, and blade is done up and down and the motion of horizontal direction under the drive of drive unit, and wire rod is cut off.Move up and down is to drive swing arm by drive unit to swing in the certain angle scope, the termination of swing arm connects the groove that horizontal direction is provided with, is furnished with slide block mutually with this groove, slide block is connected an end of knife bar, another termination blade of knife bar also is slidingly connected with the chassis that is horizontal positioned, the chassis of horizontal positioned is slidingly connected on the horizontally disposed guide rod, drives the motion of blade at above-below direction by swing arm, groove and knife bar; With respect to the horizontal guide horizontal motion, the slide block during horizontal motion in knife bar and the groove moves thereupon by the horizontal swing arm of drive unit drive and Horizontal trolley in horizontal movement, and cutting die is placed on the centre of Horizontal trolley.The cutting machine of this structure has following shortcoming: knife bar adopts horizontal channel and sliding bearing structure, and is heavy and easy to wear; Synchronized movement by tangent line material and blade is poor, and noise is big.

Summary of the invention

The purpose of this utility model provides a kind of light and handy, wearing and tearing are little, synchronized movement is strong, noise is little, easy to operate novel high speed cutting machine simple in structure, overcomes the deficiencies in the prior art.

Novel high speed cutting machine of the present utility model, it comprise swing arm that the transmission output shaft of an end and Power Drive Unit joins, knife bar, knife rest, cutting die, blade, the chassis that can move horizontally and with the horizontal guide that chassis matches, it is characterized in that:

The other end of swing arm and the upper end of knife bar are hinged with bearing pin, are slidingly connected with the vertical guide stem formation again with the hinged knife rest of another bearing pin with the lower end of knife bar;

Fixedlying connected with last chassis in the upper end of vertical guide stem, fixedlys connected with following chassis in the lower end; Last chassis and the horizontally disposed horizontal guide that goes up are slidingly connected, and following chassis and horizontally disposed horizontal guide down are slidingly connected;

Between last chassis and following chassis, be provided with the 3rd vertical guide stem, slide with the intermediate slider suit;

Eccentric shaft on intermediate slider and the driving wheel is rotationally connected, and driving wheel connects Power Drive Unit.

Novel high speed cutting machine of the present utility model, the wherein said last chassis that moves horizontally is presented down vertical placement with following chassis; Knife rest is placed on the outside of transmission intermediate slider; Cutting die is fixed on down on the chassis; Blade is fixed on the knife rest, and is included in the cutting die.

Novel high speed cutting machine of the present utility model, the track plane that an end of the swing arm of wherein said driving knife moving vertically swings up and down is parallel with the motion track face of Horizontal trolley.

Novel high speed cutting machine of the present utility model compared with prior art has following advantage: this cutting machine is by fork and the hinged form of bearing pin, and structure is light and handy, alleviate wearing and tearing and noise; Vertical chassis form of placing makes the operation workpiece be in the outside of machine, makes things convenient for and safety; Complete synchronism when having guaranteed to cut off with the chassis of horizontal movement collocation structure simultaneously, and guaranteed to cut off the perpendicularity requirement of material cut.Simple in structure, (can reach 300 times/minute) at a high speed, noise is little, easy to operate, kerf quality is high (otch can be mirror effect).During work, when being cut material level is walked in cutting die, Horizontal trolley also reaches the horizontal velocity of material, and at this moment, material is relative with cutting die static, and the blade that quilt is moved up and down vertically cuts off.

Description of drawings

Fig. 1 is the structural representation of the utility model specific embodiment;

Fig. 2 is that A shown in Figure 1 is to local enlarged diagram.

The specific embodiment

As shown in Figure 1, 2: 1 is cabinet, and Power Drive Units such as motor, decelerator are arranged in the cabinet installed inside.The output shaft of Power Drive Unit stretches out the outside and fixedlys connected with an end of swing arm 2.One end of the other end of swing arm 2 and knife bar 3 joins by rotating shaft, and the other end of knife bar 3 is rotationally connected by rotating shaft and knife rest 7.Knife rest 7 connects blade 14, and blade 14 vertically is installed in the cutting die 13, can vertically move with respect to cutting die 13.Knife rest 7 be sleeved on vertical setting and first vertical guide stem 5 that be parallel to each other and second vertical guide stem 6 on, promptly knife rest 7 can move up and down with respect to first vertical guide stem 5 and second vertical guide stem 6.Fixedly connected with last chassis 11 in the upper end of first vertical guide stem 5 and second vertical guide stem 6; Fixedly connected with following chassis 9 in the lower end of first vertical guide stem 5 and second vertical guide stem 6.Last chassis 11 is sleeved on the horizontal guide 12, can move with respect to last horizontal guide 12 horizontal directions; Following chassis 9 is sleeved on down on the horizontal guide 8, can move with respect to following horizontal guide 8 horizontal directions.All fixedly connected with the lateral surface of cabinet 1 by support in the two ends of last horizontal guide 12 and following horizontal guide 8.Between last chassis 11 and following chassis 9, be fixedly connected with the 3rd vertical guide stem 15 that is parallel to each other with first vertical guide stem 5 and second vertical guide stem 6, be set with intermediate slider 4 on the 3rd vertical guide stem 15, intermediate slider 4 can slide up and down with respect to the 3rd vertical guide stem 15.Intermediate slider 4 is installed on the horizontal driving wheel 10 by eccentric shaft 16, and laterally driving wheel 10 joins with the Power Drive Unit of cabinet 1 inboard.Described cutting die 13 is fixedlyed connected with following chassis 9.The track plane that the end that drives the swing arm 2 that blade 14 moves both vertically is swung up and down is parallel with the motion track face of Horizontal trolley.
