Description
Technical Field
The utility model belongs to the technical field of the plastic tubing production facility, concretely relates to rotatory adjustable tubular product sizing cover.
Background
The sizing link in the production of plastic pipes is generally realized by a vacuum sizing sleeve which is mainly extruded
And (3) cooling the pipe blank extruded by the die, and fixing the outer diameter size of the pipe blank and finishing the roughness of the surface of the pipe.
The method is an important factor for limiting the production efficiency of the pipe, and if the pipe is required to be rapidly produced, good cooling and rapid cooling and shaping are required.
The vacuum-pumping groove of the processing on the sizing sleeve is of a fixed size, the size of the vacuum-pumping groove cannot be adjusted according to actual conditions, and when the vacuum-pumping groove is not suitable, only one set of new equipment can be replaced.
SUMMERY OF THE UTILITY MODEL
The rotary adjustable pipe sizing sleeve is provided for solving the problems that the size of a vacuumizing groove in the prior art is fixed and cannot be adjusted.
A rotary adjustable pipe sizing sleeve comprises a sizing sleeve and an adjusting sleeve;
the sizing sleeve is a sleeve-shaped part, a middle round hole is used for a pipe to pass through, a plurality of strip holes which are arranged in a staggered array are processed on the outer wall, and the strip holes are used for conducting an inner hole of the sizing sleeve with the outside;
the inner aperture of the adjusting sleeve is matched with the diameter of the outer circle of the sizing sleeve, a plurality of second strip holes which are the same as the sizing sleeve in size and correspond to the upper positions of the sizing sleeve are machined in the adjusting sleeve, the adjusting sleeve is sleeved on the sizing sleeve, a threaded hole is formed in the adjusting sleeve, a screw is arranged in the threaded hole, and the tail end of the screw tightly pushes the outer cylindrical surface of the sizing sleeve to be fixed.
Preferably, the left end of the adjusting sleeve protrudes outwards in the radial direction to form a mounting flange, four threaded holes are formed in the mounting flange, and adjusting bolts are in threaded connection in the threaded holes.
The utility model has the advantages that: the size of the vacuum groove can be adjusted in time according to the requirements of actual production, the most appropriate working state is found, and the application range of production quality equipment is ensured to be wider.

fig. 2 is a schematic structural diagram of an adjusting sleeve according to an embodiment of the present invention.
Detailed Description
The technical solution of the present invention will be further explained with reference to the drawings in the embodiments of the present invention.
As shown in figures 1 and 2, the rotary adjustable pipe sizing sleeve comprises a sizing sleeve 1 and an adjusting sleeve 6.
The sizing sleeve 1 is a sleeve-shaped part, a middle round hole is used for a pipe to pass through, a plurality of strip holes 11 which are arranged in a staggered array are processed on the outer wall, and the strip holes 11 conduct the inner hole of the sizing sleeve 1 with the outside;
the inner aperture of the adjusting sleeve 6 is matched with the diameter of the outer circle of the sizing sleeve 1, a plurality of second strip holes which are the same as the sizing sleeve 1 in corresponding size are processed on the adjusting sleeve 6, the adjusting sleeve 6 is sleeved on the sizing sleeve 1, a threaded hole is formed in the adjusting sleeve 6, a screw 61 is arranged in the threaded hole, and the tail end of the screw 61 tightly pushes the outer cylindrical surface of the sizing sleeve 1 to be fixed.
The left end of the adjusting sleeve 6 protrudes outwards along the radial direction to form a mounting flange 63, four threaded holes are formed in the mounting flange 63, and the adjusting bolts 62 are connected in the threaded holes in a threaded mode.
As shown in figure 1, when in use, the front end of the sizing sleeve 1 is provided with a boss which is inserted into a round hole of the flange plate 2, and the flange plate 2 is clamped through the boss.
And a threaded hole is processed in the water distribution ring 3, a through hole is processed in the flange plate 2, a bolt is arranged from the side of the flange plate 2 to fixedly connect the water distribution ring 3 with the flange plate 2, and the sizing sleeve 1 is pressed and fixed.
The middle of the gland 4 is provided with a through hole for the pipe to pass through, and the pipe is arranged on the external thread of the water distribution ring through the internal thread to adjust the water flow.
It can be seen from the figure that the position relationship between the adjusting sleeve 6 and the sizing sleeve 1 is adjusted to make the strip hole 11 and the second strip hole in a staggered state, when the two are completely overlapped, the strip hole is in a completely opened state, and when the two are shielded in a staggered manner, the opening is reduced, so that the purpose of adjusting the size of the opening is achieved.
The length of the leaked elongated hole 11 can be adjusted by rotating the positional relationship of the adjustment sleeve 6.
It will be appreciated that the length direction and the rotation angle direction may also be combined. After the adjustment is carried out to a proper position, the adjustment range is wider by fixing and positioning the screw 61.
The end of the adjusting bolt 62 is tightly pressed against the flange plate 2, and the adjusting bolt 62 is screwed to push the adjusting sleeve 6 to slide on the sizing sleeve 1 in a linear distance so as to complete adjustment. After adjustment into position, the position is fixed by screws 61.
It is to be understood that although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
