Abstract
The invention discloses a hydraulic pressure multi-row link-plate type cold pipe bending machine. The hydraulic pressure multi-row link-plate type cold pipe bending machine is a cold bending device, wherein the diameter of the cold bending device is less than that of a steel pipe, and the diameter phi of the steel pipe is 219mm. The cold bending, namely, the steel pipe is in a state without application of heating, and a straight pipe is bended to a bending pipe which meets the requirement of various designed angles. Hydraulic transmission is adopted by the device, and a main shaft drive of the device is chain drive. Due to the fact that strength of extension of a common chain is low, twisting moment produced by the steel pipe bending cannot be met, a chain structure is formed by connecting the multi-row small link plate and a hinge pin. The structure has strong carrying capacity, and is solid,durable and not easy to damage. The hydraulic pressure multi-row-link-plate-type cold pipe bending machine is simple to manufacture, easy to change and low in cost.
Description
(1) technical field: in electric power, oil, chemical industry, the direction that changes pipeline often adopts bend pipe, and the design belongs to the tube manufacture apparatus field.
(2) background technology: less than the bend pipe of φ 219mm wall thickness less than 30mm, can adopt the clod wash technology due to diameter, but the production process more complicated, and sweep has fold, angular error is large.
(3) summary of the invention: the invention solves the manufacturing issue of small diameter winding pipe, propose a kind of diameter less than the cold-bending device of φ 219mm wall thickness less than the 30mm bend pipe.This device is comprised of plunger displacement pump, pumping plant, master cylinder, auxiliary oil cylinder, spindle gearing, the many rows of active plate chains, backhaul chains etc.
(4) description of drawings
Fig. 1 is the bending machine elevational schematic view: (1) auxiliary oil cylinder (2) slide plate (3) pre-bending product (4) mould (5) spindle gearing (6) many row chains plate (7) master cylinder
Fig. 2 is the bending machine schematic top plan view: (8) many rows plate chain
(5) specific embodiment: as shown in Figure 1,
(1) the pre-bending product is placed in corresponding caliber mould
(2) start plunger displacement pump and pumping plant
(3) auxiliary oil cylinder first moves and clamps the pre-bending product,
(4) many row chains of master cylinder pull bar backhaul drive plate affects main shaft together to rotate, and the pre-bending product together rotates to the angle (noticing that bend pipe has resilience, so crooked angle will add the coefficient of resilience) of bend pipe requirement, forming elbow with main shaft
(5) master cylinder playback
(6) auxiliary oil cylinder unclamps the pre-bending product
(7) unload the compacted under bend pipe.
Claims (1)
1. a caliber is made into the chaindriven hydraulic cold swan neck system of many rows of bend pipe, its feature less than the 30mm straight tube less than φ 219mm wall thickness:
This device adopts hydraulic drive, and its spindle drive is the chain transmission, and chain is combined into structure by what the little carrier bar of many rows connected with bearing pin, and the state forming that do not heating of the straight tube that bends in advance.
