The utility model has the advantages that: compare with traditional sizing cover, this scheme designs the sizing cover for length combination formula sizing cover, and in the actual production process, can freely allocate length according to body cooling process, has reduced repeated preparation sizing cover cost, has shortened production cycle, has improved production and has transferred quick-witted efficiency.
Description
Technical Field
The utility model relates to the field of medical equipment, more specifically say and relate to a length combination formula sizing cover that is used for medical expansion pipe to extrude cooling design.
Background
When the pipe body is subjected to extrusion molding, the pipe body needs to penetrate through the sizing sleeve and enter a cooling water tank for cooling and shaping, when the pipe body is excessively cooled or insufficiently cooled, the length of the cooling section of the sizing sleeve can be adjusted by changing the length of the cooling section of the sizing sleeve, but most manufacturers use the straight-through type integral sizing sleeve at present, the length of the cooling section of the sizing sleeve in production cannot be changed, and the sizing sleeve can only be manufactured again. For example, when different specifications of the medical catheter sheath expanding tube are extruded, the length of the sizing sleeve can be flexibly changed according to the production condition to control the cooling and shaping effects of the tube body, thereby controlling the size precision of the tube.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes the defects in the prior art and provides a length combined type sizing sleeve for extrusion cooling and shaping of a medical expansion pipe.
The purpose of the utility model is realized by the following technical scheme.
The utility model provides a length combination formula sizing cover for medical expansion pipe extrusion cooling is stereotyped, includes cooling fin, cushion and locating lever, the locating lever welding is on spare part, the cover is equipped with a plurality of cooling fins on the locating lever, and is a plurality of be equipped with between the cooling fin the cushion.
Furthermore, the number of the positioning rods is 1-3.
Furthermore, the tail part of the positioning rod is provided with threads, and the threads are matched with nuts to prevent the cooling fins from being separated from the positioning rod.
Furthermore, the cooling sheet is provided with a through hole for penetrating through the positioning rod.
Further, the thickness of the cooling fin becomes thinner from the thickness in the distribution direction away from the component.
Further, the spacing between the cooling fins is from narrow to wide in the distribution direction away from the component.
Cooling fin and cushion thickness change design reason, the entrance body just begins the cooling, and the temperature is high, and is softer, needs the cooling fin intensive, realizes the body and fully cools off, and along with the pipe hardens gradually, cooling fin thickness can reduce, and the interval also can increase gradually.
The utility model has the advantages that:
compare with traditional sizing cover, this scheme designs the sizing cover for length combination formula sizing cover, and in the actual production process, can freely allocate length according to body cooling process, has reduced repeated preparation sizing cover cost, has shortened production cycle, has improved production and has transferred quick-witted efficiency.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure:
1. a cooling fin; 2. cushion blocks; 3. positioning a rod; 4. and (4) parts.
Detailed Description
The technical solution of the present invention is further explained by the following specific examples.
As shown in fig. 1, a length-length combined sizing sleeve for extrusion cooling shaping of a medical expansion pipe comprises cooling fins 1, a cushion block 2 and a positioning rod 3, wherein the positioning rod 3 is welded on a part 4, the positioning rod 3 is sleeved with a plurality of cooling fins 1, the cushion block 2 is arranged between the plurality of cooling fins 1, the cushion block 2 is used for controlling the distance between grooves of the cooling fins 1, and the distance between the cooling fins 1 is the same as the thickness of the cushion block 2; the number of the positioning rods 3 is 1-3, preferably the number of the positioning rods 3 is 3, the length of each positioning rod is designed according to the wall thickness of the pipe and the material used, the thicker the wall thickness of the pipe body is, the longer the length of each positioning rod is, and meanwhile, the higher the processing temperature of the pipe body material is, the longer the length of each positioning rod is; the tail part of the positioning rod 3 is provided with threads which are matched with nuts for use so as to prevent the cooling fins 1 from being separated from the positioning rod 3; the cooling fin 1 is provided with a through hole for penetrating the positioning rod 3; the thicknesses of the adjacent cooling fins 1 may be different, and the thicknesses of the adjacent spacers 2 may be different.
The thickness of the cooling fins 1 becomes thinner from thick in the distribution direction away from the component 4, and the interval between the cooling fins 1 becomes narrower to wider in the distribution direction away from the component 4. The principle of designing the thickness of the cooling fin and the thickness of the cushion block is as follows: the entrance body just comes out from the mould, and the temperature is high, and the body is softer, and easy deformation if the cooling fin is too thin, and the recess interval is too big, and the body surface is easily inhaled, influences the body outward appearance, so need the cooling fin thick, and the interval is less, and along with the pipe hardens gradually, cooling fin thickness can reduce, and the interval also can increase gradually.
The working process is as follows:
when the sizing sleeve is used, the positioning rod 3 is welded on the part 4, the cooling fins 1 are continuously stacked on the positioning rod 3 according to needs, the length of the cooling segment of the sizing sleeve can be freely increased or shortened by increasing or reducing the number of the cooling fins 3, and the sizing sleeve can be freely prepared according to the cooling process in production.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
