Abstract

The utility model relates to a main pressing wheel mechanism of a pre-welding machine. The main pressing wheel mechanism comprises a screw rod, wherein the screw rod is arranged on a top beam; a main pressing wheel support is arranged on the screw rod; main pressing wheels are arranged on the main pressing wheel support; the screw rod and the main pressing wheel support are connected through a driving oil cylinder; two of the four main pressing wheels are vertically arranged from front to back and the other two of the four main pressing wheels are obliquely arranged front left to right and in a shape like an inverted Chinese character eight; and a driver is connected to the main pressing wheels. With the adoption of the main pressing wheel mechanism, the two pressing wheel arranged vertically exert a balance effect on gaps of steel pipes, and the two pressing wheel arranged in the shape like the inverted Chinese character eight can be used for providing lateral pressure for the steel pipes so as to facilitate gap closing; and the driver drives the main pressing wheels, so that the delivery of the steel pipes can be facilitated, the production efficiency of an enterprise can be improved, the production cost is saved, and the economic benefit is increased.

Description

The main pressing wheel mechanism of Prewelding machine
Technical field
The utility model relates to the welding equipment in the mechanical field, especially relates to a kind of main pressing wheel mechanism that is used for Prewelding machine.
Background technology
Before steel pipe was carried out prewelding, great majority all can close up operation to steel pipe, in order that when prewelding, can reach needed flatness; Generally close up all just adopt main pinch roller between the slit roll extrusion, sometimes because the dynamics on both sides is not enough, when winner's pinch roller is pressed; The slit does not close up fully, causes in welding, can not reaching the purpose of closing up welding, and the slit is excessive or do not weld; Occurrence of waste has increased the cost of product export.
The utility model content
The utility model technical problem to be solved provides a kind of main pressing wheel mechanism of Prewelding machine, and it not only can smooth slit, but also can when left and right sides dynamics is little, the increase dynamics close up the slit.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of main pressing wheel mechanism of Prewelding machine, comprise the screw rod that is installed on the back timber, and main pinch roller support is installed on the screw rod, main pinch roller support is equipped with main pinch roller.
For ease the automation roll extrusion is carried out in the slit of steel pipe, described screw rod is connected through driving oil cylinder with main pinch roller support.
When making in the left and right sides that dynamics is not enough, can increase left and right sides dynamics and close up the slit, and play the effect in smooth slit, described main pinch roller has four, and wherein vertically place two front and back, and inclination of falling the Eight characters is placed about two other.
Steel pipe is carried for ease, is connected with driver on the described main pinch roller, drives main pinch roller and rotates.
The beneficial effect of the utility model is: adopt above-mentioned main pressing wheel mechanism, two pinch rollers of vertically placing play smooth effect to the steel pipe slit, and the pinch roller of the placement of falling the Eight characters can provide lateral pressure to steel pipe about two, conveniently closes up the slit; Driver drives master's pinch roller can make things convenient for the conveying of steel pipe, improves the production efficiency of enterprise, has saved production cost, has increased economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of the utility model Fig. 1.
Among the figure: 1, back timber; 2, screw rod; 3, driving oil cylinder; 4, vertical main pinch roller;
5, the master's of falling Eight characters pinch roller; 6, main pinch roller support.
The specific embodiment
The main pressing wheel mechanism of a kind of Prewelding machine as depicted in figs. 1 and 2 comprises the screw rod 2 that is installed on the back timber 1, and main pinch roller support 6 is installed on the screw rod 2, and main pinch roller support 6 is equipped with main pinch roller; Described screw rod 2 is connected through driving oil cylinder 3 with main pinch roller support 6; Described main pinch roller has four, and wherein two front and back vertically are placed as vertical main pinch roller 4, and inclination of falling the Eight characters is placed as the master's of falling Eight characters pinch roller 5 about two other; Be connected with driver on the described main pinch roller.
When using main pressing wheel mechanism; Elder generation is according to the size of product diameter; Through screw rod 2 main pressing wheel mechanism is adjusted to suitable height, machine then, control driving oil cylinder 3 moves down main pinch roller support 6; Vertical main pinch roller 4 smooth slits in the main pinch roller support 6, the master's of falling Eight characters pinch roller 5 is used to close up the slit.
This kind mechanism can reduce the appearance of waste product, increases the efficient of finished product, has reduced the cost that dispatches from the factory, and increases economic benefit of enterprises.
