Description

A kind of cutting knife device of tire belt cutting machine

Technical field

The present invention relates to the shape that a kind of fabric sandwich with tire such as casing ply cut into requirement, especially a kind of cutting knife device of tire belt cutting machine.

Background technology

We know that tire half steel belt cutting machine is mainly used in wirecord fabric is cut into the belt that meets technological requirement, uses for next procedure.Tire half steel belt is the main stressed member of radial, it will bear higher shear stress than bias tire cushion, also to realize simultaneously the suffered stress of tyre surface mild transition, avoid the phenomenon of coming to nothing at tire shoulder position, so tire half steel belt compound has higher brute force, fatigue durability, heat resistance and cohesive.And cut-off knife is as one of essential elements of cutting machine, and just seem particularly important the service life of cut-off knife and the convenience of replacing etc.

At present, the cutting knife device of tradition cutting machine, it comprises a base, tool rest once, cutter once, cutter pressing plate once, lead, one upper cutter head, one upper slitter and a upper slitter pressing plate, lower tool rest is bolted and is connected on the base, lower cutter is pressed by lower cutter pressing plate, and fixedly be assemblied in lower tool rest through bolt, upper slitter is pressed by the upper slitter pressing plate, and fixedly be assemblied in upper cutter head through bolt, lead vertically is fixed on the base, upper cutter head is sleeved on the lead, moved back and forth at lead by the drive unit driving, make between upper slitter and the lower cutter and shear mutually, and the severing tire belt.The cutting knife device of the cutting machine of said structure, in use, upper slitter, lower cutter easily produce wearing and tearing, the continuous tire belt of cutting is under the extruding of upper slitter and lower cutter, shearing force effect, easily enter between the cutter seam of upper slitter and lower cutter, cause lower tool rest displacement, and can not normally cut.

Summary of the invention

In order to overcome in the prior art the easily deficiency of displacement of lower cut-off knife seat, the invention provides a kind of cutting knife device of simple in structure, reasonable in design, service-strong tire belt cutting machine.

The technical solution adopted for the present invention to solve the technical problems is: a kind of cutting knife device of tire belt cutting machine, it comprises a base, tool rest once, cutter pressing plate once, cutter once, one upper cutter head, one upper slitter, one upper slitter pressing plate and lead, described lead vertically is fixed on the described base, described upper cutter head is sleeved on this lead, described lower tool rest is fixedly connected on described base through set bolt, described lower cutter is pressed by described lower cutter pressing plate, and fixedly be assemblied on the described lower tool rest through lower cutter gim peg, described upper slitter is pressed by the upper slitter pressing plate, and fixedly be assemblied on the described upper cutter head through the upper slitter gim peg, it is characterized in that: it also comprises some top screw seats, each top screw seat all is comprised of the vertical jackscrew with of horizontal connection part section, its cross section is L-type, described top screw seat is fixedly connected on described base by silk seat bolt through its horizontal connection part, be provided with the tapped through hole of level in the vertical jackscrew section of described top screw seat, lean on the end face of described lower tool rest with the end of the top bolt of this tapped through hole threaded engagement.

The present invention is provided with top screw seat at base, lean on the end face of lower tool rest with the end of the top bolt of tapped through hole threaded engagement on this top screw seat, lower tool rest is under the acting in conjunction of top bolt, set bolt, prevented that effectively time tool rest from producing displacement, make between upper slitter and the lower cutter and can not produce the gap, thereby guaranteed normally cutting of upper slitter and lower cutter.Compared with prior art, the present invention has simple in structure, reasonable in design, service-strong advantage.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is a kind of structure master's cutaway view of the present invention;

Fig. 2 is that A among Fig. 1 is to view.

Among the figure: 1. base, 2. set bolt 3. descends tool rest, 4. descend the cutter gim peg, 5. descend cutter, 6. descend the cutter pressing plate, 7. upper slitter, 8. upper slitter gim peg, 9. upper slitter pressing plate, 10. upper cutter head, 11. leads, 12. top screw seats, 1201. horizontal connection part, 1202. vertical jackscrew sections, 1203. tapped through holes, 13. the top bolt, 14. seat bolts.

The specific embodiment

In Fig. 1, a kind of cutting knife device of tire belt cutting machine, it comprises a base 1, once tool rest 3, once cutter pressing plate 6, once cutter 5, a upper cutter head 10, a upper slitter 7, a upper slitter pressing plate 9 and lead 11.

As shown in Figure 1, lead 11 vertically is fixed on the base 1, and upper cutter head 10 is sleeved on the lead 11.Upper cutter head 10 is driven at lead 1 by drive unit and moves back and forth.

As shown in Figure 1, upper slitter is pressed by upper slitter pressing plate 9, and fixedly is assemblied on the upper cutter head 10 through upper slitter gim peg 8.

As shown in Figure 1 and Figure 2, lower tool rest 3 is fixedly connected on base 1 through seven set bolts 2.Lower cutter 5 is pressed by lower cutter pressing plate 6 and fixedly is assemblied on the lower tool rest 3 through nine lower cutter gim pegs 4.

In Fig. 1, Fig. 2, a kind of cutting knife device of tire belt cutting machine, it also comprises three top screw seats 12.

As shown in Figure 1 and Figure 2, each top screw seat 12 all is comprised of the vertical jackscrew with of a horizontal connection part 1201 section 1202, and its cross section is L-type.Vertical jackscrew section 1202 at top screw seat is shaped with tapped through hole 1203.

In Fig. 1, Fig. 2, three top screw seats 12 are fixedly connected on base 1 by silk seat bolt 14 through its horizontal connection part 1201.

With tapped through hole 1203 threaded engagement top bolt 13 is arranged, the end of this top bolt 13 leans on the end face of lower tool rest 3.Lower tool rest 3 has prevented that effectively time tool rest 3 from producing displacement, can not produce the gap between upper slitter 7 and the lower cutter 5 under the acting in conjunction of top bolt 13, set bolt 2, guaranteed normally cutting of upper slitter and lower cutter, thereby the maximum access times of performance cut-off knife are increased work efficiency, and reduce the cut-off knife maintenance cost.
