Description

Technical Field

[0001] The invention relates to the technical field of protective tubes, and in particular to a quick auxiliary shaping device for a cable plastic protective tube. Background Art

[0002] Cable plastic protection tube is a tubular material used to protect wires and cables from mechanical damage and other external factors. The protection tube is usually made of various types of plastics, such as polyvinyl chloride PVC, polyethylene PE, polypropylene PP, etc. Plastic materials have good insulation properties, corrosion resistance and certain flexibility, making them an ideal choice for cable protection. In order to better protect the cables during the installation process and ensure the beauty and safety of the installation, the protection tube needs to be bent and shaped.

[0003] In the existing patent CN214488408U, a pre-bending device for a cable protection tube is disclosed, including a main body, a side plate is fixedly installed on the left side of the lower end face of the main body, a lower bracket is fixedly installed on the left side of the lower end face of the side plate, four supporting legs 1 are symmetrically installed on the lower end face of the lower bracket, and a rotating motor is fixedly installed on the upper end face of the lower bracket. The side clamping plate 1 and the side clamping plate 2 are driven by the driving motor 1 to move in the guide rail, so that cable protection tubes of different sizes can be fixed, and the anti-skid pad 1 and the anti-skid pad 2 are used to prevent the cable protection tube from moving during the pre-bending process to increase the friction force, and the adjustment seat is driven by the driving motor 2 to move left and right on the pre-bending seat, so as to adjust the pre-bending size of the cable protection tube, and the heating tube connected to the heater is inserted into the cable protection tube to soften it, so that the cable protection tube will not break during pre-bending due to the influence of low temperature.

A transmission component 11 is provided on the force-applying component 10. When the connecting component 9 connects the transmission component 11 with the rotating mechanism 5, the rotating mechanism 5 causes the force-applying component 10 to generate force.

[0040] Working principle: When the protective tube is bent and shaped, the protective tube is passed through the support ring 4, the detection component 7 and the heating component 6, and the pushing component 2 is used to drive the support bending component 3 to move to a reasonable position, so that the support bending component 3 forms a supporting effect on both ends of the protective tube, and the rotating mechanism 5 is started to force the heating component 6 to rotate. At the same time, the power is turned on so that the heating component 6 performs annular heating on the protective tube. The heating component 6 rotates slowly. When the heating component 6 heats the protective tube to a certain extent, the protective tube can be bent. At this time, the detection component 7 detects the temperature and forces the adjustment component 8 to move, so that the adjustment component 8 adjusts the rotation speed of the rotation mechanism 5.

Within a certain rotation speed range, the annular heating temperature of the protective tube by the heating component 6 is gradually increased. During this process, the rotation speed of the rotating mechanism 5 is gradually increased. Within a unit time, the force of the force-applying component 10 on the supporting and bending component 3 is gradually increased, so that the supporting and bending component 3 drives the protective tube to quickly complete the bending effect. After bending, the heating effect of the heating component 6 is stopped, and the shaping action of the protective tube is completed, so that the pushing component 2 and the supporting and bending component 3 return to their original positions, and the bent and shaped protective tube is removed; in summary, a rapid auxiliary shaping device for a cable plastic protective tube of the present application increases the force applied to the protective tube within a unit time during the bending process of the protective tube, so that the force applied to the protective tube is uniform, and the number of bending times of the protective tube is increased, thereby achieving a rapid bending effect on the protective tube, and achieving a supporting and protecting effect on the protective tube, so that the stress of the protective tube at the bending point is dispersed, thereby reducing the phenomenon of protective tube breakage, improving the auxiliary shaping ability of the protective tube, facilitating the bending shaping and protection of the protective tube, and improving the bending shaping efficiency of the protective tube.

A limit block 1203 is arranged on the latch 1202, and the limit block 1203 abuts against the fixed block 1201, and a spring 1204 is arranged between the latch 1202 and the fixed block 1201.

[0051] like Figure 1 , Figure 4 , Figure 6 and Fig. 9 As shown, a quick auxiliary shaping device for a cable plastic protective tube of the present invention, the transmission component 11 includes a mounting block 1101 arranged on a support ring 4, a bearing on the mounting block 1101 is connected to a sleeve 1102 sleeved on the outer ring of the output shaft of the motor 501, a bearing on the mounting block 1101 is connected to a rotating rod 1103, an outer ring of the sleeve 1102 is fixedly sleeved with a driving bevel gear 1104, a driven bevel gear 1105 meshing with the driving bevel gear 1104 is fixedly sleeved on the rotating rod 1103, a pulley 1106 is fixedly sleeved on the rotating rod 1103 and one of the shafts 1002, and the two pulleys 1106 are connected through a belt 1107 for transmission.

[0052] Working principle: When the protective tube is bent and shaped, the protective tube is passed through the support ring 4, the annular temperature sensing sheet 703 and the multiple hot air nozzles 601, so that the bending point is located at the hot air nozzle 601, and the fan-shaped electromagnet 203 is energized, and the fan-shaped electromagnet 203 attracts the fan-shaped slider 301 to form a supporting effect, and the hydraulic push rod 202 is started. The output end of the hydraulic push rod 202 drives the fan-shaped electromagnet 203 to move, thereby causing the fan-shaped slider 301 to move, driving the hydraulic push rod 202 to move. The second rod 302, the electric push rod 303 and the arc plate 304 move, so that the position of the second hydraulic push rod 302 abuts against the block 1008, and the second hydraulic push rod 302 is started at the same time, so that the second hydraulic push rod 302 drives the electric push rod 303 and the arc plate 304 to move to the inside of the protection tube, and the electric push rod 303 is started, so that the output end of the electric push rod 303 drives the arc plate 304 to move until the arc plate 304 contacts the inner wall of the protection tube, forming a supporting and protective effect on the protection tube;

[0053] The motor 501 is started, and the output shaft of the motor 501 rotates to drive the driving gear 503 to rotate, the driving gear 503 drives the driven gear 504 to rotate, the driven gear 504 drives the rotating ring 502 to rotate, and the rotating ring 502 drives the hot air nozzle 601 to rotate, so that the conductive contact block 602 is always in contact with the conductive slide rail. When the conductive slide rail is powered on, the hot air nozzle 601 is connected to the power supply, so that the hot air nozzle 601 continuously heats the bending point of the protection tube; thereby achieving the effect of forming a ring-shaped heating around the protection tube;

[0054] Since the heating nozzle forms a ring-shaped heating on the protection tube, the heating temperature of the protection tube gradually increases within a certain speed range. When the speed exceeds a certain level, the heating time of the heating nozzle on the protection tube is short, so the temperature will drop.

[0055] When the surroundings of the protection tube are gradually raised to a certain temperature, the annular temperature sensing piece 703 senses the temperature. When the expansion temperature of the expansion airbag 701 is reached, the annular temperature sensing piece 703 transfers the temperature to the expansion airbag 701 through the heat-conducting rod 702, so that the expansion airbag 701 is heated and expands. The expansion of the expansion airbag 701 compresses the gas in the cylinder 801, so that the gas drives the piston 802 to move, the piston 802 drives the adjustment rod 803 to move, the adjustment rod 803 drives the conductive adjustment piece 805 to move, and the conductive adjustment piece 805 moves on the resistance strip 804, so that the electric The resistance value of the resistance bar 804 decreases, so that the current passing through the circuit increases, so that the electromagnet block 901 repels the magnet stone 905, so that the magnet stone 905 moves, and the magnet stone 905 drives the support rod 904 to move, the support rod 904 drives the annular sleeve 903 to move, and the annular sleeve 903 drives the friction table 902 to move, so that the friction table 902 moves to the sleeve 1102, so that the sleeve 1102, the friction table 902 and the output shaft of the motor 501 are closely contacted to form a whole, wherein the motor 501, the electromagnet block 901 and the resistance bar 804 are connected in series in the circuit;

[0056] At this time, under the action of the friction table 902, the output shaft of the motor 501 rotates to drive the sleeve 1102 to rotate, the sleeve 1102 rotates to drive the active bevel gear 1104 to rotate, the active bevel gear 1104 drives the driven bevel gear 1105 to rotate, so that the rotating rod 1103 rotates, the rotating rod 1103 drives the pulley 1106 to rotate, and under the action of the belt 1107, the shaft 1002 rotates;

[0057] The shaft 1002 rotates to drive the rotating gear 1003 to rotate. Since the two rotating gears 1003 are meshed, the rotation directions of the two rotating gears 1003 are opposite. The shaft 1002 rotates to drive the turntable 1004 to rotate. The positions of the teeth 1005 on the two turntables 1004 are different, and the two teeth 1005 are separated. When one of the teeth 1005 contacts the spur rack 1006, the spur rack 1006 moves upward, and the spur rack 1006 meshes with the latch 1202, so that the spur rack 1006 drives the latch 1202 to rotate, and the latch 1202 compresses the spring 1204. After the spur rack 1006 moves a process, the spring 1204 returns to its original state, so that the latch 1202 and the limit block 1203 limit the spur rack 1006. 006 drives the connecting rod 1007 to move, and the connecting rod 1007 drives the resistance block 1008 to move. The resistance block 1008 exerts a force on the hydraulic push rod 302, so that the hydraulic push rod 302 overcomes the attraction of the fan-shaped electromagnet 203 to the fan-shaped slider 301, so that the fan-shaped slider 301 slides a process in the fan-shaped slide groove 204. At this time, the other tooth 1005 is not in contact with the straight rack 1006, and the latch 1202 and the limit block 1203 form a limit effect on the straight rack 1006, so that the other hydraulic push rod 302 does not move, so that the hydraulic push rod 302, the electric push rod 303 and the arc plate 304 form a support effect on the protection tube, which is convenient for the hydraulic push rod 302, the electric push rod 303 and the arc plate 304 on the other side to bend the protection tube;

[0058] Within a certain speed range, the heating temperature of the protection tube gradually increases, so that the rotation speed of the motor 501 gradually increases, thereby forming positive feedback within a certain speed range. When the speed of the motor 501 increases, the frequency of the force applied by the two resistance blocks 1008 to the hydraulic push rod 2 302 gradually increases, and the two resistance blocks 1008 apply force crosswise, so that the two ends of the protection tube are evenly stressed, so that the protection tube is bent multiple times in the heated state, and the device can quickly bend the protection tube within a unit time.

[0059] The hot air nozzle 601 is a prior art. According to the working principle of the hot air nozzle 601, the hot air nozzle 601 is generally formed by a heating resistance wire and a fan. When the resistance wire is heated, the fan blows out hot air to form hot air. Before the bending is completed, the resistance wire is turned off, but the fan is allowed to continue to operate. At this time, the bent protection tube is blown by cold air, causing the protection tube to cool down rapidly. At the same time, the annular temperature sensing sheet 703 transfers the temperature to the expansion airbag 701 through the heat conducting rod 702. At this time, due to the decrease in the internal temperature of the expansion airbag 701, the expansion airbag 701 is forced to contract, causing the piston 802 and the adjusting rod 803 to retreat. The adjusting rod 803 drives the conductive adjusting sheet 805 to move, and the conductive adjusting sheet 805 moves in the opposite direction on the resistance bar 804, causing the resistance bar 804 to The resistance value increases, so that the current passing through the circuit decreases, so that the repulsive force generated by the electromagnet block 901 on the magnet stone 905 decreases, so that the magnet stone 905 moves back, and the magnet stone 905 drives the support rod 904 and the annular sleeve 903 to move back, and the annular sleeve 903 drives the friction round table 902 to move back, so that the sleeve 1102 is separated from the output shaft of the motor 501. At this time, the transmission component 11 and the force component 10 do not move. Under the action of the driving gear 503 and the driven gear 504, the output shaft of the motor 501 drives the rotating ring 502 to rotate, so that the fan on the hot air nozzle 601 performs annular blowing to cool the bending part of the protection tube, so that the protection tube is quickly shaped, and the purpose of the device for quickly bending and shaping the protection tube is achieved;

[0060] After the bending and shaping are completed, the motor 501 is stopped, and the electric push rod 303 drives the arc plate 304 to retreat, the hydraulic push rod 2 302 drives the electric push rod 303 and the arc plate 304 to retreat, and the hydraulic push rod 1 202 retreats to the original position in sequence, and the protective tube and the wave spring 1204 are removed, so that the two spur racks 1006 retreat to the original position;

[0061] The setting of the pushing component 2 can drive the movement of the supporting and bending component 3, improve the flexibility of the supporting and bending component 3, and when supporting the protective tube, the supporting and bending component 3 is first retreated, and after passing through the protective tube, the supporting and bending component 3 is advanced, thereby achieving support for the protective tube, facilitating the operation of the protective tube, and improving the rationality of the device; the setting of the supporting and bending component 3 can provide a supporting effect for the protective tube, so that the arc plate 304 forms support for the inner wall of the protective tube, improves the stability of the protective tube, and at the same time, when the protective tube is bent, one side is supported and the other side is bent, thereby improving the flexibility and rationality of the device; the setting of the rotating mechanism 5 can provide power to enable the heating component 6 to generate The protection tube is heated evenly by rotation. At the same time, the transmission component 11 drives the force-applying component 10 to move, thereby providing power to the force-applying component 10. By using the same driving source, the integrated function of the device is improved, making the device more energy-efficient. The setting of the heating component 6 can provide uniform heat to the protection tube, thereby achieving the effect of forming an annular heating on the protection tube. At the same time, during the heating process, the temperature gradually increases. The effect of the temperature increase is cleverly used to control the rotation speed of the motor 501, thereby achieving positive feedback of the device within a certain speed range. The setting of the detection component 7 can detect the temperature around the bending point of the protection tube, so that the temperature is transmitted to the adjustment component 8, and the annular temperature sensor sheet 703 can make the temperature closer to the temperature on the protection tube, expand the airbag 701 to change the volume in the cylinder 801, and thus change the pressure in the cylinder 801; the setting of the adjustment component 8 can realize the use of temperature changes by the device, realize the force on the piston 802 in the cylinder 801, so that the adjustment rod 803 adjusts the resistance value of the resistor bar 804, realizes the feedback effect on the device, improves the automatic adjustment ability of the device, and improves the flexibility and versatility of the device; the setting of the connecting component 9 can realize the connection between the rotating mechanism 5 and the transmission component 11, improve the control ability of the motor 501, enable the device to heat the protection tube in an annular manner, and can transmit the force of the motor 501 to the force-applying component 10, realizes the resistance effect on the hydraulic push rod 2 302, and at the same time can realize the separation between the rotating mechanism 5 and the transmission component 11, so that the rotating mechanism 5 moves alone, improving the flexibility and controllability of the device; the setting of the force-applying component 10 can realize the effect of supporting one side of the protective tube and bending the other side when the protective tube is bent, so that the latch 1202 and the limit block 1203 form a limit on the straight rack 1006, so that the device accumulates force, so that the straight rack 1006 continues to rise, and when bending, the resistance block 1008 moves with the hydraulic push rod 2 302, thereby continuously cross-bending the two ends of the protective tube, improving the rationality of the device;The transmission assembly 11 can transmit the rotational force of the motor 501 to the resistance block 1008, so that the resistance block 1008 pushes the hydraulic push rod 2 302, so that the fan-shaped slider 301 moves in the fan-shaped slide groove 204, thereby achieving a bending effect on the protection tube and an auxiliary shaping effect on the protection tube;

[0062] During the bending process of the protective tube, this solution increases the force applied to the protective tube per unit time, so that the force applied to the protective tube is uniform, and the number of bending times of the protective tube is increased, thereby achieving a rapid bending effect on the protective tube, and achieving a supporting and protective effect on the protective tube, so that the stress of the protective tube at the bending point is dispersed, thereby reducing the phenomenon of breakage of the protective tube, improving the auxiliary shaping ability of the protective tube, facilitating the bending shaping and protection of the protective tube, and improving the bending shaping efficiency of the protective tube. This device is particularly suitable for connecting bends at the connection points of two cable plastic protective tubes.
