Embodiment 1

[0015] Example 1: as figure 1 As shown in the figure, the pipe sizing sleeve device of the present invention includes: a sizing sleeve main body 1 and a fixing sleeve 5; one end of the sizing sleeve main body 1 is provided with a diversion groove 2 and a water outlet 3, and the water outlet is used to facilitate the diversion of water. The cooling water circulating in the groove 2 is led out; the fixing sleeve is used to prevent the cooling water in the diversion groove 2 from flowing out, so that the guiding groove 2 forms a closed cooling water system; the fixing sleeve 5 is arranged on the main body 1 of the sizing sleeve and has The water inlet 4 communicated with the guide groove 2; the water inlet can facilitate the injection of cooling water into the guide groove 2. In order to prevent the cooling water from overflowing, a sealing ring 8 is also provided between the contact surface of the fixed sleeve 5 and the main body 1 of the sizing sleeve.

[0016] In order to bet...

Embodiment 2

[0021] like figure 2 As shown, compared with Embodiment 1, the overall structure of this embodiment is basically the same, and the difference only lies in the structure of the heat sink 6 . As shown in the figure, in this embodiment, the heat sink 6 adopts a piece of metal sheet and is arranged in a spiral shape along the bottom surface of the guide groove 2 , so that a single thread is formed inside the guide groove 2 .

[0022] Since the metal sheet is spirally arranged inside the guide groove 2, the circulating water flow channel 7 formed inside the metal sheet is also spirally arranged, that is, the circulating water flow channel 7 is a spiral groove. In order to increase the flow rate of cooling water, the helical groove is preferably configured as a rectangular thread shape. Since the metal sheet forms a single thread inside the diversion groove 2, only one circulating water flow channel 7 is formed inside the heat sink 6 formed by the metal sheet. In order to ensure t...

Embodiment 3

[0024] like image 3 As shown, compared with Embodiment 2, the overall structure of this embodiment is basically the same, the difference is that the number of metal sheets arranged inside the diversion groove is more than 2, that is, these metal sheets are all along the direction of the diversion groove 2. The bottom surface is helically arranged to form a multi-start thread shape. Correspondingly, more than two circulating water flow channels 7 are formed inside the heat sink 6 .

[0025] Therefore, it can be deduced that when several pieces of metal sheets are spirally arranged along the bottom surface of the guide groove 2 in the guide groove 2, several circulating water flow channels 7 are correspondingly formed inside it.

[0026] The present invention has the following advantages:

[0027] (1) The structure is simple, the cost is low, and the use is convenient.

[0028] (2) There are radiating fins inside the diversion groove, thereby improving the heat dissipation e...

Abstract

The invention discloses a pipe sizing sleeve device. The pipe sizing sleeve device comprises a sizing sleeve main body and a fixing sleeve; one end of the sizing sleeve main body is provided with flow guide grooves and water outlets; the fixing sleeve is arranged on the sizing sleeve main body and is provided with a water inlet communicated with the flow guide grooves; a seal ring is also arranged between contact surfaces of the fixing sleeve and the sizing sleeve main body; the inner parts of the flow guide grooves are also provided with heat radiating fins with circulation water circulation channels; both the water inlet and the water outlets are communicated with the circulation water flow channels; the heat radiating fins are stamped once. The pipe sizing sleeve device provided by the invention is simple in structure, can accelerate the water flow speed, cooling water has small possibility of remaining in the device, and thus accelerating heat dissipation and refrigeration for plastic pipe blanks.

Description

technical field [0001] The invention relates to a sizing sleeve device, in particular to a pipe sizing sleeve device for producing plastic pipes. Background technique [0002] In the process of producing plastic pipes, it is necessary to use sizing sleeves to cool the hot-melt stretched plastic pipe blanks. At present, the commonly used sizing sleeve is provided with an annular guide groove for the circulation of cooling water, and finally the plastic pipe is cooled. However, because the cooling water in the traditional sizing sleeve annular diversion groove cannot effectively participate in the circulation, it is easy to stay in the backflow groove to form circulating dead water, which slows down the cooling water heat dissipation rate and seriously affects the production efficiency. SUMMARY OF THE INVENTION [0003] The invention provides a pipe sizing sleeve device with simple structure, which can speed up the water flow, and the cooling water is not easy to stay, so a...
