Abstract
The mandrel chain support guiding device of the rod inserting machine comprises a left connecting plate seat and a right connecting plate seat which are symmetrical and comprise a connecting plate and side steps, wherein the side steps are arranged on the right side surface of the connecting plate, mounting holes are formed in the side steps, and chain pin holes are formed in two ends of the connecting plate; the left side and the right side of the V-shaped core rod guide block are both provided with connecting steps, and the V-shaped core rod guide block is supported on the left connecting plate seat and the right connecting plate seat through the connecting steps on the left side surface and the right side surface and is fixed by screws. As the supporting structure of the V-shaped core rod guide block is changed, the shaft hole supporting structure is changed into the plane supporting structure, when the V-shaped core rod guide block is stressed, the V-shaped core rod guide block is decomposed on the connecting steps at the left side and the right side, and after use verification, the performance of the core rod guide device with the structure is stable, the problem that the connection between the V-shaped core rod guide block and the left connecting plate seat and the connection between the V-shaped core rod guide block and the right connecting plate seat are unreliable is thoroughly eliminated, and the reliability of the plunger chain transmission device in the seamless steel tube rolling unit is improved.
Description
Technical field:
The present invention relates to the seamless steel tube production technical field, relate in particular to the plunger chain bar transmitting device in the seamless steel pipe tube rolling unit.
Background technology:
The tube rolling unit is one of key equipment in the seamless steel tube production process, the plunger machine is to be used for the circulating chain transmit machine that plunger is carried, it is a transmit machine important in the tube rolling unit, this circulating chain transmission plunger machine is by two synchronization chains spaced apart, the drive synchronization-moving sprocket wheel of chain and several equidistantly are fixed on two V-type plug guide blocks between the chain and form, the at present general circulating chain strip transmission line of plunger machine is identical with the double-chain synchronous pipeline that heavy industry machine-building Co., Ltd in Sanming City, Shanxi produces, between the chain of two layouts that are parallel to each other, equally spaced be provided with several plugs supporting gatherers, described plug supporting gatherer as shown in Figure 2, it comprises that a left side that is fixedly mounted on the left chain connects panel seat 1, the right side that is fixedly mounted on the right chain connects panel seat 2 and V-type plug guide block 3, a described left side connects panel seat 1 and comprises connecting plate and side mandrel, and the side mandrel is arranged on the right flank of connecting plate, be provided with the connecting hole with pitches such as chains at the two ends of connecting plate, be convenient to be fixedly mounted on the chain; The structure of described right connection panel seat 2 is identical with left side connection panel seat 1, and it also comprises connecting plate and side mandrel, and the side mandrel is provided with on the left surface of connecting plate; Left and right sides face at V-type plug guide block 3 is equipped with the mandrel hole, and the mandrel hole is connected panel seat 1 and matches with the right side mandrel that is connected on the panel seat 2 with a left side.Because the diameter of side mandrel is less, after V-type plug guide block 3 is sleeved on the mandrel of side, also the axial limiting pin need be set on the mandrel of side, in case V-type plug guide block 3 produces play at work.The plug gatherer of this structure in actual use, the mandrel fracture often appears, a left side connects panel seat 1 and the right side, and to be connected panel seat 2 are consumable accessorys in this equipment, the fault rate that therefore the plunger machine produces is very high, trace it to its cause mainly be V-type plug guide block 3 stressed after, active force all concentrates on the mandrel of side, because the diameter of side mandrel is limited, the pressure that the side mandrel is born is too big, thereby causes side mandrel fracture.V-type plug guide block 3, a left side connect panel seat 1 and the right syndeton that connects between the panel seat 2 is unreasonable, must improve it.
Summary of the invention:
The plug chain supporting gatherer that the purpose of this invention is to provide a kind of plunger machine.
The technical scheme that the present invention takes is as follows:
The plug chain supporting gatherer of plunger machine, comprise that a left side connects panel seat 1, right panel seat 2 and the V-type plug guide block 3 of connecting, a described left side connects panel seat 1 and comprises connecting plate 11 and side step 12, and side step 12 is arranged on the right flank of connecting plate 11, on side step 12, be provided with the fixed installation hole 13 that is used to install V-type plug guide block 3, be provided with chain pin-and-hole 14 at the two ends of connecting plate 11 with pitches such as chains; Equally, the described right panel seat 2 that connects also comprises connecting plate 21 and side step 22, and side step 22 is arranged on the left surface of connecting plate 21, on side step 22, be provided with the fixed installation hole 23 that is used to install V-type plug guide block 3, be provided with chain pin-and-hole 24 at the two ends of connecting plate 21 with pitches such as chains; Left and right sides face at V-type plug guide block 3 is equipped with the side step 12 and the right side step 22 corresponding connection steps 31 that are connected panel seat 2 that is connected panel seat 1 with a left side, the connection step 31 of V-type plug guide block 3 by left and right sides face is bearing in side step 12 and right the connection on the side step 22 of panel seat 2 that a left side connects panel seat 1, and fixed by screw 4.
Be connected panel seat 1 owing to changed V-type plug guide block 3 with a left side, the right supporting structure that connects between the panel seat 2, change simple axis hole supporting structure into the larger area planar supporting structure, after V-type plug guide block 3 is stressed, active force promptly is broken down into a left side and connects panel seat 1, on the side step of right connection panel seat 2, because the bearing area of side step is bigger 5～6 times than effective bearing area of original side mandrel, so the shear strength that side step is subjected to has only 1/5～1/6 of side mandrel, actual use checking through 150 days, the plug gatherer stable performance of this structure, thoroughly eliminated V-type plug guide block 3 and be connected panel seat 1 with a left side, the right connection connects insecure problem between the panel seat 2, greatly improve the reliability of plunger chain transmitting device in the seamless steel pipe tube rolling unit, thereby improved the tube rolling efficient and the tube rolling quality of whole tube rolling production line.
