Abstract
The utility model discloses extruding and forming equipment of square and rectangular pipes, comprising a loading platform frame (1), a pushing oil cylinder (2) and an extruding and forming roll (3). The extruding and forming equipment is characterized in that a medium-frequency heating coil (4) is arranged between the pushing oil cylinder (2) and the extruding and forming roll (3). The extruding and forming equipment is improved on the basis of the original production equipment, the medium-frequency heating coil is added before secondary forming, flexible deformation of steel pipes is realized by controlling the temperature and the time of medium-frequency heating, and the length of the heating sections of the steel pipes, and the phenomena of fracture and tearing of the steel pipes produced originally are eliminated.
Description
Affiliated technical field
The utility model belongs to the process equipment of steel pipe, is a kind of extrusion formation equipment of square tube particularly.
Background technology
In the prior art, the production technology of heavy caliber thick wall square tube is mostly taked circle change side secondary roller press type molding mode.The equipment that adopts comprises: feeding skid, pushing oil cylinder, be squeezed into forming roll, pipe is delivered to be squeezed in the forming roll by the pushing oil cylinder on feeding skid and is pushed.But, this equipment has the following disadvantages: when the high material steel pipe of production and processing heavy wall pipe, the phenomenons such as fine cracks that mother metal phenomenon of rupture and inner surface fold and outer surface are torn often appear at the knuckle place, cause the steel pipe of production not reach standard-required, a large amount of waste products and substandard products steel pipe appear, cause the unnecessary waste of raw material, so the moulding problem of thick walled steel tube and high material steel pipe is the difficult problem of puzzlement processing enterprise always.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved square tube extrusion formation equipment is provided, and its structure is provided with advantages of simple, and is easy to operate, and the square tube quality of extrusion modling is good, and is no damaged.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: feeding skid, pushing oil cylinder, be squeezed into forming roll, it is characterized in that: at the pushing oil cylinder and be squeezed into and be equiped with the heating in medium frequency coil between the forming roll.
The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, satisfactory pipe is placed on the feeding skid, and steel pipe is delivered to pushing oil cylinder porch by feed mechanism, with the pushing oil cylinder with steel pipe deliver to be squeezed into forming roll before, with the heating in medium frequency coil steel pipe is carried out online heating, adjust heating-up temperature and push system speed according to different calibers, material, wall thickness.According to the technological parameter requirement, adjust the pass of forming frame, the steel pipe after the heating is delivered in the forming frame, again through sizing, aligning, anti-ly produce satisfactory steel pipe after turning round frame.The utility model improves on the basis of original production equipment, before post forming, increase the heating in medium frequency coil, realize the plastic deformation of steel pipe by the length of temperature, time and steel pipe bringing-up section of control heating in medium frequency, removed the steel pipe fracture of original production and torn phenomenon.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the structure diagram of the utility model embodiment.
Mark among the figure: 1-feeding skid, 2-pushing oil cylinder, 3-are squeezed into forming roll, 4-heating in medium frequency coil.
The specific embodiment
By shown in Figure 1, the utility model includes: feeding skid 1, pushing oil cylinder 2, be squeezed into forming roll 3, at pushing oil cylinder 2 and be squeezed into and be equiped with heating in medium frequency coil 4 between the forming roll 3.
The square tube of the utility model processing detects through every index, and requirement all is up to state standards.
Claims (1)
1. square tube extrusion formation equipment, it includes: feeding skid (1), pushing oil cylinder (2), be squeezed into forming roll (3), it is characterized in that: at pushing oil cylinder (2) and be squeezed into and be equiped with heating in medium frequency coil (4) between the forming roll (3).
