Abstract
A shaping clamp is characterized by comprising a clamp body and a step sleeve; the clamp body is formed by combining two arch-shaped block-shaped bodies, through holes are formed in opposite positions of two ends of each arch-shaped block-shaped body and are fixed into a whole through bolts, a cavity is formed in the middle of the clamp body, six threaded holes are uniformly distributed in the cavity in the radial direction and matched with adjusting bolts, one end of each adjusting bolt in the cavity is connected with a pressing plate, and the six pressing plates can form a ring shape in the cavity; the step sleeve is placed in the circular ring shape, the step sleeve is divided into two parts along the diameter direction, a 90-degree chamfer is arranged in an inner hole at one end of the step sleeve with the step, the 90-degree chamfer is a conical angle taking the hole center line of the inner hole as a symmetry axis, and the included angle between the inclined edge of the conical angle and the hole center line is 90 degrees. The cavity is circular; the pressing plate is arc-shaped; the diameter of the inner hole of the step sleeve is equal to the outer diameter of the pipe. The utility model discloses economy, conveniently carry, work efficiency is high. One end of the expanded and shaped pipe is connected with the pipe joint, so that the sealing performance is good.
Description
Technical Field
The utility model relates to an auxiliary fixture, specificly relate to an anchor clamps of centre gripping plasticity pipe especially non ferrous metal plasticity pipe one end with its inflation and plastic.
Background
When the plastic pipe of non ferrous metal and the pipe joint are assembled and connected manually, one end of the pipe needs to be clamped by an auxiliary clamp, and the punch is utilized to expand and form a boss with a certain angle in the length direction of the pipe, so that one end of the pipe can be well sealed and fastened with the pipe joint.
At present, an auxiliary clamp for expanding and shaping one end of a pipe can only be suitable for clamping one pipe diameter and cannot be suitable for clamping one ends of pipes with various diameter specifications during expanding and shaping, so that the auxiliary clamp is not economical and convenient to carry and influences the working efficiency; particularly, when the expansion and shaping of one end of the nonferrous metal pipe are needed during the outgoing repair, the problems of inconvenient carrying and influence on the working efficiency are more prominent, for example, a hydraulic control pipeline of a machine tool or an air conditioner condensation pipeline during the outgoing repair, an auxiliary clamp capable of clamping one end of a plurality of pipes with different diameters is needed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an eliminate above phenomenon, need solve: there is no auxiliary clamp suitable for clamping one end of pipes with various diameter specifications and expanding and shaping.
A shaping clamp is characterized by comprising a clamp body and a step sleeve; the clamp body is formed by combining two arc-shaped block bodies, through holes are formed in opposite positions of two ends of each arc-shaped block body and are fixed into a whole through bolts, a cavity is formed in the middle of the clamp body, six threaded holes are radially and uniformly distributed in the cavity, the threaded holes are matched with adjusting bolts, one end of each adjusting bolt in the cavity is connected with a pressing plate, and the six pressing plates can form a ring shape in the cavity; the step sleeve is placed in the annular shape, the step sleeve is divided into two parts along the diameter direction, and an inner hole at one end of the step sleeve with steps is provided with a chamfer.
The cavity is circular;
the pressing plate is arc-shaped;
the diameter of the inner hole of the step sleeve is equal to the outer diameter of the pipe.
The utility model discloses economy, conveniently carry, work efficiency is high. The device can clamp one end of a non-ferrous metal pipe with various diameter specifications, and then expand and reshape one end of the pipe into a boss with a certain angle by using a punch.

FIG. 2 is a schematic top view of the present invention.
FIG. 3 is a front view of the step cover of the present invention.
FIG. 4 is a schematic top view of the step cover of the present invention.
In the figure, 1 bolt, 2 clamp bodies, 3 arch-shaped block bodies, 4 adjusting bolts, 5 pressing plates, 6 step sleeves, 7 cavities, 8 chamfers and 9 steps.
As shown in fig. 1, 2, 3 and 4, the shaping jig is characterized by comprising a jig main body 2 and a step collar 6. The clamp body 2 is formed by combining two arc-shaped block bodies 3, through holes are formed in opposite positions of two ends of each arc-shaped block body 3 and are fixed into a whole through bolts 1, a cavity 7 is formed in the middle of the clamp body 2, six threaded holes are radially and uniformly distributed in the cavity 7 and matched with adjusting bolts 4, one end, in the cavity 7, of each adjusting bolt 4 is connected with a pressing plate 5, and the six pressing plates 5 can form a ring shape in the cavity 7; a step sleeve 6 is arranged in the circular ring shape, the step sleeve 6 is divided into two parts along the diameter direction, and an inner hole at one end of the step sleeve 6 with a step 9 is provided with a chamfer 8.
The cavity 7 is of a circular shape,
the pressing plate 5 is in the shape of an arc,
the diameter of the inner hole of the step sleeve 6 is equal to the outer diameter of the pipe.
Detailed Description
The utility model discloses technical scheme realizes like this:
(1) According to the outer diameter of the nonferrous metal tube, a step sleeve 6 with the inner hole diameter equal to the outer diameter is selected,
(2) The position of the pressure plate 5 in the cavity 7 is adjusted by rotating the six adjusting bolts 4, so that the six pressure plates 5 form a circular ring shape matched with the excircle of the step sleeve 6,
(3) One end of the nonferrous metal tube is arranged in an inner hole of the step sleeve 6 and extends out with a proper length, and the step sleeve 6 is combined into a whole along the diameter direction.
(4) Six adjusting bolts 4 are rotated to tightly press the pressure plate 5 against the outer circle of the step sleeve 6 until the nonferrous metal tube is tightly clamped.
(5) One end of the pipe is expanded by a punch and is shaped into a boss with a certain angle along the chamfer 8, and the acting force of the punch is counteracted by the step 9 of the step sleeve 6.
(6) The six adjusting bolts 4 are unscrewed, the pressing plate 5 is separated from the outer circle of the step sleeve 6, and the step sleeve 6 is divided into two parts along the diameter direction, so that the non-ferrous metal pipe is separated from the fastening clamping. Take out the utility model.
One end of the expanded and shaped pipe is connected with the pipe joint, so that the sealing performance is good.
