Description
Technical Field
The invention relates to the field of rubber, in particular to the field of rubber tube forming.
Background
The rubber tube has the performances of ultraviolet resistance, ozone resistance, high and low temperature resistance (-80 to 300 ℃), high transparency, strong resilience, compression resistance, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, flame resistance, voltage resistance, electric conduction and the like, is suitable for various severe working environments, and is greatly developed in production.
At present, the commonly used rubber tube molding equipment is an extrusion device, rubber raw materials are heated to a molten state, then the rubber raw materials are extruded and molded by a special extrusion device, and then the rubber raw materials are cooled and cut. Because the cross section of the rubber tube is circular, the extrusion device generally comprises a cylindrical die on the periphery and a cylindrical die core positioned in the die, the molten raw material enters the die and is positioned between the die and the die core, and simultaneously the raw material is cooled and shaped into the rubber tube after being cooled. In order to promote the shaped rubber pipe to leave the die, the rubber pipe needs to be pulled towards the discharging end continuously, but because the inner wall of the rubber pipe is attached to the die core, the friction force applied to the rubber pipe is large in the process, and the pulling force is also needed for pulling the rubber pipe, so that the rubber pipe is easy to stretch and deform. Secondly, the rubber tube slides relative to the mold core, and the inner wall of the rubber tube is easily abraded.
Disclosure of Invention
The invention aims to provide a rubber tube forming device which reduces the pulling force required for pulling a rubber tube so as to reduce the deformation of the rubber tube.
In order to achieve the purpose, the technical scheme of the invention is as follows: a rubber tube forming device comprises a rack, a stepping motor, an extrusion tube arranged along the horizontal direction and a mold core mechanism positioned in the extrusion tube, wherein the stepping motor and the extrusion tube are fixed on the rack; the mold core mechanism comprises a liquid inlet pipe, a liquid outlet pipe, a piston, an inner rod and a rotating shaft, wherein the inner rod and the rotating shaft are arranged along the horizontal direction, the stepping motor can drive the inner rod to rotate, an accommodating cavity is arranged in the inner rod, at least one opening is formed in the side wall of the accommodating cavity along the circumferential direction, an elastic sheet is arranged outside the opening and fixed on the outer wall of the inner rod, a plurality of first magnets are embedded in the elastic sheet, and a second magnet which can repel the first magnets and can deform the elastic sheet by repulsive force is fixed on the rotating shaft; the piston is positioned in the accommodating cavity and is in threaded fit with the rotating shaft, a plurality of balls are arranged between the piston and the rotating shaft, a sliding groove is formed in the side wall of the accommodating cavity along the axial direction of the inner rod, and a sliding block capable of sliding along the sliding groove is fixed on the piston; and a liquid inlet one-way valve and a liquid outlet one-way valve are respectively fixed in the liquid inlet pipe and the liquid outlet pipe and are communicated with the accommodating cavity.
The principle of the scheme is as follows:
after the melting raw materials got into the extrusion pipe, be located between extrusion pipe and the interior pole, be located promptly and hold the chamber periphery, the cooling water can be followed the feed liquor pipe and got into and hold the chamber, cools off the raw materials that gets into the extrusion pipe, makes the raw materials stereotype gradually, forms pipy rubber tube rudiment. When the stepping motor drives the rotating shaft to rotate, the second magnet can rotate along with the rotating shaft, and the magnetic force between the first magnet and the second magnet is also continuously changed along with the change of the distance between the second magnet and the first magnet. When the second magnet is close to the first magnet, the magnetic force is increased, and finally the elastic sheet is elastically deformed by the magnetic force to extrude the gradually-shaped rubber tube prototype to the outer periphery; magnetic force reduces when first magnet is kept away from to second magnet, the flexure strip resets, and at this whole in-process, heat in the rubber tube gets into the cooling water that holds in the chamber gradually, the rubber tube is further stereotyped, so the flexure strip resets the back, the rubber tube is difficult to reset, form the gap between rubber tube and the interior pole, can not laminate completely between rubber tube inner wall and the interior pole, be promptly under the unchangeable condition of the coefficient of friction of interior pole, area of contact between rubber tube and the interior pole reduces, so frictional force between rubber tube and the interior pole also reduces, it is corresponding, the required pulling force of pulling rubber tube reduces.
When the rotating shaft rotates, the piston is in threaded fit with the rotating shaft, and the roller and the sliding block which are arranged between the piston and the rotating shaft can only slide along the sliding groove, so that the piston slides along the rotating shaft, and the space on two sides of the piston is changed, thereby cooling water can enter the containing cavity from the liquid inlet pipe and be discharged from the liquid outlet pipe.
The beneficial effect of this scheme does:
repulsive force is generated between the second magnet and the first magnet, and the repulsive force can deform the elastic sheet, so that the diameter of the inner cavity of the rubber tube which is not completely shaped is increased; and after the elastic sheet resets, the rubber tube is further shaped due to the cooling effect of the cooling liquid, so the rubber tube cannot reset, the rubber tube cannot be completely attached to the inner rod, the abrasion degree of the inner wall of the rubber tube is reduced, the friction force between the rubber tube and the inner rod is reduced, the pulling force required for pulling the rubber tube is reduced, and the rubber tube cannot deform under the action of the pulling force.
(two) the coolant liquid can follow the feed liquor pipe and get into and hold the chamber, and the heat that gets into in the intraductal melting raw materials of extrusion transmits earlier on the interior pole, then during transmitting the coolant liquid, then the drain pipe discharge can be followed to the coolant liquid, so the temperature of rubber tube reduces gradually, and the rubber tube is stereotyped gradually, so hold the intracavity and add the coolant liquid and can shorten the required time of rubber tube design, improve production efficiency.
And thirdly, as the sliding block slides along the sliding groove, when the rotating shaft rotates, the sliding block cannot rotate relative to the sliding groove, so that the piston rotates along the rotating shaft at the moment, and when the rotating shaft is rotated forwards and backwards by the stepping motor, the piston can reciprocate, so that the sizes of spaces on two sides of the piston are continuously changed, new cooling liquid enters the accommodating cavity, heat is continuously discharged along with the cooling liquid in the accommodating cavity, and the cooling liquid in the accommodating cavity keeps a better cooling effect.
Preferably, as a further improvement of the basic aspect, the rotating shaft includes a rotating shaft coaxial with the extrusion tube and a rotating blade fixed to the rotating shaft, and the second magnet is fixed to the rotating blade. Under the condition that the diameters of the rotating shaft and the inner rod are not changed, the second magnet is located on the rotating blade, and the rotating blade is fixed on the rotating shaft, so that when the rotating blade is close to the first magnet, the distance between the second magnet and the first magnet is smaller, the repulsive force between the second magnet and the first magnet is larger, and the elastic piece is further guaranteed to be capable of generating elastic deformation.
Preferably, as a further improvement to the first preferred embodiment, the number of the rotating blades and the number of the second magnets are both two, and the included angle between the two rotating blades is 180 °. Because the inlet pipe constantly to adding the melting raw materials in extruding the pipe, the raw materials can flow along extruding the pipe after getting into the extrusion pipe, under the extrusion of raw materials, when having the gap between rubber tube and interior pole, the rubber tube of not finalizing the design easily moves to being close to interior pole one side again. Set up two rotor blades, the axis of rotation rotates a week, and the number of times that first magnet and second magnet met is twice, and the number of times that the flexure strip took place deformation also is twice, so the number of times that the rubber tube received the flexure strip effect is twice, so under the unchangeable condition of axis of rotation slew velocity, can have more times to let the rubber tube stereotype, just be difficult for after the rubber tube stereotypes to the interior pole motion of rethread under the extrusion of raw materials, further keep the gap between rubber tube and the interior pole.
Preferably, scheme three, as the further improvement to basic scheme, the drain pipe is located the chamber that holds and is close to inlet pipe one end with the intercommunication department that holds the chamber, and the feed liquor pipe is located the axis of rotation, and the feed liquor pipe is located the chamber that holds with the intercommunication department that holds the chamber and keeps away from inlet pipe one end. The material enters the extrusion tube from the feed tube and then moves towards the end remote from the feed tube, during which the heat in the material is gradually transferred to the cooling liquid in the receiving chamber, so that the temperature of the rubber tube remote from the end of the feed tube is lower. The cooling liquid just entering the accommodating cavity does not start to absorb heat, the temperature is the lowest, and the cooling liquid can absorb the heat on the rubber tube with the reduced temperature after entering the accommodating cavity, so that the cooling effect of the rubber tube is further improved.
Preferably, as a further improvement of the basic aspect, a seal ring is fixed to the outer periphery of the piston. The sealing ring plays a role in sealing, the cooling liquid in the accommodating cavity is prevented from penetrating through a gap between the piston and the accommodating cavity, and the effects of discharging and sucking the cooling liquid are better.
Preferably, the fifth scheme is a further improvement of the basic scheme, a cooling channel is further arranged in the side wall of the extrusion pipe, and the cooling channel is communicated with an external cooling water pipe. The rubber tube can be cooled after cooling water enters the cooling channel, so that the cooling effect of the rubber tube is further improved, and the forming efficiency is improved.
