Abstract

The utility model relates to a sizing device for a high-speed extruding machine of a spirally-wound section bar. The sizing device comprises a machine head and a negative-pressure sizing device, wherein the machine head and the negative-pressure sizing device are arranged on an extruding machine. The sizing device is characterized in that the negative-pressure sizing device consists of a cavity, circulating water jackets and a negative-pressure air suction sleeve; the circulating water jackets are arranged outside the cavity; the negative-pressure air suction sleeve is arranged outside the circulating water jackets and is communicated with the interior of the cavity through miniature air suction holes. The sizing device for the high-speed extruding machine of the spirally-wound section bar is scientific and reasonable in structural design; a sizing sleeve consists of the circulating water jackets and the negative-pressure air suction sleeve; by additionally arranging a water cooling system, after the shape of a section bar is extruded in a high-rate machine head, the section bar can be fully cooled in the sizing sleeve to ensure that the structural shape of the section bar does not deform, so that the uniformity of lamination clearances between buckles which are manufactured on the spirally-wound section bar is improved, and the rigidity and tightness of a new pipe which is manufactured by spiral winding are improved.

Description

Spiral winding section bar high-speed extruder diameter-setting equipment
Technical field
The utility model belongs to the pipe rehabilitation technology field, particularly a kind of spiral winding section bar high-speed extruder diameter-setting equipment.
Background technology
At present, the situation that China's subsoil drain is long neglected and in disrepair is very general, produce the effluent seepage phenomenon because subsoil drain is damaged, severe contamination groundwater resources, and cause and descend partly soil erosion to produce cavity, serious situation causes the ground local collapse, brings very large threat to the people's life.Now China mainly adopts traditional digging mode to be changed to the reparation of subsoil drain, not only welding but also affect traffic.China adopts in drainage inspection well and is wound around and produces the novel plastic pipeline also in blank.The applicant develops a kind of section bar of can spiral winding making the enhancement mode pipeline, this section bar forms pipeline by the shackle designs spiral pressing of self, also need to be coordinated with steel band simultaneously, therefore, particularly important to the quality that is wound around tubulation to the shape stability of section bar.
Traditional profile shapes all adopts extruder to pass through extrusion molding after the mould of head, and carries out sizing by cooling device.But, the cooling diameter-setting equipment of existing Profile Extrusion head, cooling velocity is slow, does not reach the production requirement of winding section.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of spiral winding section bar high-speed extruder diameter-setting equipment is provided, and it is fast that it has cooling velocity, guarantees the precise and stable advantage of profile shapes.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of spiral winding section bar high-speed extruder diameter-setting equipment, comprise the head and the negative pressure diameter-setting equipment that are arranged on extruder, it is characterized in that: described negative pressure diameter-setting equipment consists of die cavity, cyclic water jacket and negative-pressure air-suction cover, in the die cavity outer setting, cyclic water jacket is arranged, outer setting at cyclic water jacket has the negative-pressure air-suction cover, and the negative-pressure air-suction cover is communicated with in die cavity by the air draught micropore.
And described cyclic water jacket is to be disposed on die cavity outer 3-5, each cyclic water jacket is provided with circulating water intake and circulating water outlet.
Advantage of the present utility model and beneficial effect are:
This spiral winding section bar high-speed extruder diameter-setting equipment, scientific structure design is reasonable, its calibration sleeve consists of cyclic water jacket and negative-pressure air-suction cover, by increasing a water-cooling system, after in the two-forty head, extruding shape, cooling more abundant in calibration sleeve at section bar, guarantee profile structure shape invariance shape, thereby it is even to improve between snap close made on the spiral winding section bar pressing gap, improve rigidity and the tightness of the new pipe that spiral winding makes.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-negative-pressure air-suction cover, 2-circulating water intake, 3-cyclic water jacket, 4-air draught micropore, 5-bolt, 6-circulating water outlet, 7-die cavity, 8-section bar, 9-head.
The specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of spiral winding section bar high-speed extruder diameter-setting equipment, comprise the head 9 and the negative pressure diameter-setting equipment that are arranged on extruder, wherein, the negative pressure diameter-setting equipment consists of die cavity 7, cyclic water jacket 3 and negative-pressure air-suction cover 1, and die cavity is that the mould by the two halves formula is fixedly mounted with and forms by bolt 5.In the die cavity outer setting, cyclic water jacket is arranged, cyclic water jacket is to be disposed on die cavity outer 3-5, and each cyclic water jacket is provided with circulating water intake 2 and circulating water outlet 6.Cyclic water jacket is connected with outside circulation.Outer setting at cyclic water jacket has the negative-pressure air-suction cover, and the negative-pressure air-suction cover is communicated with in die cavity by air draught micropore 4.The position of air draught micropore between adjacent cyclic water jacket.
Operation principle of the present utility model is:
This spiral winding section bar high-speed extruder diameter-setting equipment, section bar 8 is after the head section of extruder is extruded, and traction enters in the die cavity of diameter-setting equipment, under suction function, is adsorbed on the die cavity inwall, simultaneously under the cyclic water jacket effect, cooling and shaping.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
