The compound sley bar of steel pipe
Technical field
The present invention relates to braiding apparatus technical fields, more particularly to the guide bar assembly of high speed lace tricot machine.
Background technique
In Knitting Machinery, using the fabric of tricot machine braiding flower pattern complexity, tricot machine drives flower card wire to transport by sley bar
It is dynamic, it is woven into fabric to realize and will knit line.The sley bar of high speed lace tricot machine is typically all that steel wire is made currently on the market
, with shape point, it can be generally divided into two kinds, one is slot is equipped on steel wire sley bar, as shown in Figure 1, the slot is direct
Milled out on steel wire with milling cutter come, the floricome to match with sley bar is on slot, as shown in Figure 4.Another kind is steel wire
There is no slot on sley bar, floricome with steel wire sley bar is connect with glue.Existing steel wire sley bar, has the disadvantage that
1. there is channel steel silk sley bar, as shown in Figure 1, slot is located on steel wire, when finding zero-bit, i.e. along the axis of steel wire in Fig. 1
Line needs vertical with the A plane in Fig. 3, and slot is L at a distance from joint, and since slot and screw thread are apart from, this is in practical operation
In be extremely difficult to.
2. as shown in Fig. 2, using slotted steel wire as sley bar, active force is on steel wire sley bar, on centre of force line
Discontinuity, and since the slot is to be milled out with milling cutter come there are stress on steel wire sley bar, then steel wire sley bar
It is easily deformed, is broken.
3. shown in Fig. 3 is 24 needle sley bars, at a distance of 4.233mm i.e. 4 needle gage (needle gage 1.058mm) between slot and slot,
If client need to use 62 needle gages, 62 be not 4 integer, therefore has channel steel silk sley bar using existing, is not able to satisfy absolutely mostly
The demand of number client.
4. it is 132 inches that commonly use has channel steel silk sley bar length currently on the market, to have slot wire comb with 210 inches
Comb, nearly six meters of sley bar length, need nearly 6 meters, diameter be 2mm steel wire on processing groove technique too complex.
Common also another steel wire sley bar is slotless steel wire sley bar currently on the market, and glue is used between floricome and sley bar
Connection need to first remove glue when changing flower pattern kind every time from sley bar and remove needle, then cleaned arrangement bonds again again, consumption
Take too many man power and material.
Utility model content
In order to solve the above-mentioned technical problem, a kind of compound sley bar of steel pipe is provided.
The purpose of the present invention is what is be achieved through the following technical solutions.
Technical solution of the present invention: providing a kind of compound sley bar of steel pipe, and the compound sley bar of the steel pipe is combed by solid wireline
Comb part and hollow steel pipe sley bar part composition, several steel tubing portions cover on cable segments, then with glue by steel wire portion
Divide and steel tubing portions bonding, the steel tubing portions are equipped with card slot.
Further, the size of the card slot is depth * wide=0.3-0.4*0.3-0.4.
Further, one end of the steel pipe is equipped with protrusion, and the other end is equipped with groove, each section of steel pipe end to end on set
The groove for having protrusion and matching with protrusion, keeps the connection between steel pipe and steel pipe more compact.
The invention has the benefit that since slot separates with steel wire manufacture, when determining sley bar zero point, it is only necessary to one
Standard floricome and 364.3 measurers.Then with glue, (steel pipe can rotate on steel wire before cementing, can also be on steel wire
It is mobile, to be easily directed at position).For 132 inches of sley bar, after 3 minutes glue is dry, zero position is determined, then will
13 steel pipes head and the tail put on a sley bar.It can according to need arrangement odd and even number needle gage, meet the need of different clients
It asks.And due to the cable segments in compound sley bar, without slot, when active force is on compound sley bar, compound sley bar is unlikely to deform,
Fracture.

Specific embodiment
Embodiment 1
As shown in Fig. 4 the structural schematic diagram of steel pipe sley bar, wherein the #1 in Fig. 4 is drag hook connector, and #2 is steel wire, #3
It is steel pipe, #4 is the connector of wirerope.Steel pipe #3 is covered forms compound sley bar on steel wire #4, according to the slot pitch and steel pipe on steel pipe
Quantity, to determine the length and needle gage of sley bar.It is connected between steel pipe and steel wire by glue.The outer diameter of steel pipe is
2.0mm, internal diameter 1.36mm.The internal diameter of gauge of wire and steel pipe matches.
Fig. 5 is enlarged diagram at I in Fig. 4, and as shown in Figure 4, needle gage 2.117 is 24 needle gages 2, from B at C
Needle gage is the even-multiple of 2 needle gages, can arrange all even number needle gages, and determine sley bar using the steel pipe of different number
Length.
Embodiment 2
Needle gage from from A to B is a 1.058 i.e. needle gage, on even number needle gage add a needle gage, odd number needle
Away from.
