Abstract
The invention provides a fixture device of a cold press molding machine for elbows. The fixture device comprises a pair of extrusion heads including a straight extrusion head and a bent extrusion head. The straight extrusion head is of a solid cylinder structure, the bent extrusion head is of a bent solid cylindrical structure, opposite ends of the straight extrusion head and the bent extrusion head are trapezoidal respectively, the straight extrusion head and the bent extrusion head are of complementary structures, in other words, the two ends of the straight extrusion head and the bent extrusion head can be completely matched with each other, the other ends of the bent extrusion head and the straight extrusion head are respectively connected with a hydraulic press, the bent extrusion head and the straight extrusion head are placed in an arc groove in a worktable, a 30-degree angle is formed between the horizontal plane and a tangent plane of an arc surface of a side of the trapezoidal end of the bent extrusion head, and a 41-degree angle is formed between the perpendicular direction and a tangent plane of an arc surface at the other end of the bent extrusion head. The fixture device has the advantages that a straight circular tube section to be machined is extruded to form an elbow by the aid of the bent extrusion head and the straight extrusion head of the integral fixture device, accordingly, an integral machining procedure is safe and reliable, an elbow machining process can be improved, and the elbow machining quality and the elbow machining efficiency can be enhanced.
Description
Technical field
The present invention relates to a kind of grip device of elbow chilling press.
Background technology
Along with steel pipe and the mankind's life, the relations of production are more and more tightr, its application is more and more extensive, in steel pipe application, often there will be the situation such as pipeline turning or shunting, can be applied to bend pipe or elbow, and wherein, elbow is widely used to connect, to change convenient.In the production and processing of elbow, mostly adopted vertical nip drum ball forming pattern in the past, process is comparatively complicated, and spin work in-process easily rolls out, life is threatened safely, therefore provide a kind of safe and reliable, convenient and simple bend forming grip device is necessary in fact.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the present invention has developed a kind of grip device of elbow chilling press, comprise a pair of extrusion head, be respectively straight extrusion head and curved extrusion head, described straight extrusion head is solid cylinder body structure, described curved extrusion head is bending filled circles column structure, the described straight extrusion head termination relative with curved extrusion head is respectively trapezoidal shape, and both become complementary structure, two terminations can fit like a glove, described curved extrusion head is connected with hydraulic press respectively with the straight extrusion head other end separately, described curved extrusion head and straight extrusion head are positioned in the arc groove on workbench, the arc surface tangent plane of the trapezoidal shape termination side of described curved extrusion head becomes 30 ° of angles with horizontal plane, the arc surface tangent plane of the other end becomes 41 ° of angles with vertical direction.
The invention has the beneficial effects as follows:
Whole device, by a pair of curved straight extrusion head, is squeezed into elbow by straight pipe section to be processed, and whole process safety is reliable, has changed vertical nip drum ball forming pattern in the past, has improved the processing technology of elbow, has improved crudy and the efficiency of elbow.
Brief description of the drawings
Fig. 1 is top view of the present invention.
Wherein, the straight extrusion head of 1-, the curved extrusion head of 2-, 3-workbench, 4-arc groove.
Detailed description of the invention
As shown in Figure 1, the grip device of a kind of elbow chilling press of the present invention, comprise a pair of extrusion head, be respectively straight extrusion head 1 and curved extrusion head 2, described straight extrusion head 1 is solid cylinder body structure, described curved extrusion head 2 is bending filled circles column structure, described straight extrusion head 1 is respectively trapezoidal shape with the relative termination of curved extrusion head 2, and both become complementary structure, two terminations can fit like a glove, described curved extrusion head 1 is connected with hydraulic press respectively with straight extrusion head 2 other end separately, described curved extrusion head 1 and straight extrusion head 2 are positioned in the arc groove 4 on workbench 3, the arc surface tangent plane of the trapezoidal shape termination side of described curved extrusion head 1 becomes 30 ° of angles with horizontal plane, the arc surface tangent plane of the other end becomes 41 ° of angles with vertical direction.
When the present invention works, curved extrusion head 1 and straight extrusion head 2 are positioned in the arc groove 4 on workbench 3, and there is a segment distance between two trapezoidal shape terminations, hollow straight pipe to be bent is positioned in the arc groove 4 of this dead band, one end of pipe is enclosed within on curved extrusion head 1, open the hydraulic press that connects straight extrusion head 2, straight extrusion head 2 advances to the direction of curved extrusion head 1, until two trapezoidal shape terminations join, hollow circular-tube is shifted onto on curved extrusion head 1 by whole, thereby straight tube is become to curved, complete elbow processing.
