Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, in particular to an emergency stop device used in cable mold production. Background Art

[0002] Emergency power-off devices interrupt the power supply to a machine or system to avoid danger in an emergency. Therefore, emergency stops provide a higher level of safety and are used in most machines, reducing the probability of device damage and reducing damage costs.

[0003] At the same time, a cable production extrusion die with application number 202322510585.9 relates to the field of mold technology, including: a cable production device body and a cooling component, a limiting component, the limiting component including a mold core, a limiting block fixed on the outer surface of one side of the mold core, a plurality of leakage holes opened on the outer surface of the limiting block, and a plurality of bolts movably embedded inside the limiting block; in the utility model, when it is necessary to produce and form the insulation layer on the surface of the cable, the raw materials for cable production are first transported to the interior of the cable production device body through the feed port, and the cable production raw materials enter the interior of the extrusion die. Through the action of the limiting component, the position offset between the mold core and the mold sleeve is effectively prevented from affecting the quality of the cable molding, thereby solving the problem in the prior art that the mold core and the mold sleeve are easily offset due to external squeezing when the cable is extruded, resulting in the quality of the molded cable not meeting the standards.

[0004] When a problem occurs in an existing cable production extrusion die during use, resulting in cable quality problems, the device cannot be stopped urgently, which may damage the device, increase costs, increase the production of substandard cables, and reduce profits.

[0005] Therefore, in order to solve the above problems, an emergency stop device for cable mold production is proposed. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides an emergency stop device for cable mold production, which has the advantage of being able to urgently stop the cable mold production device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an emergency stop device for cable mold production, comprising a workbench, the internal rotation of the workbench is connected to a bidirectional threaded rod, the outer side of the bidirectional threaded rod is spirally connected to a slide, one side of the upper part of the slide is fixedly connected to a clamp, one side of the clamp is provided with a cable body, the outer side of the bidirectional threaded rod is fixedly connected to a gear, the outer teeth of the gear are connected to a block, and the internal rotation of the block is connected to a support rod.

[0008] Preferably, a support plate is fitted on the bottom end of the workbench, a hydraulic rod is fixedly connected to the bottom end of the support plate, a protective box is fixedly connected to the bottom end of the hydraulic rod, an opening and closing door is rotatably connected to the top of the protective box, and a warning light is fixedly connected to the top end of the slide.

[0009] Preferably, one end of the bidirectional threaded rod is fixedly connected to a servo motor, and the servo motor is outside the workbench.

[0010] Preferably, a bearing is sleeved on the outer side of the bidirectional threaded rod, and the bearing is embedded in the inside of the workbench.

[0011] Preferably, a guide block is fixedly connected to the bottom end of the slide plate, there are two guide blocks, and the guide blocks slide inside the workbench.

[0012] Preferably, a torsion spring is sleeved on the outer side of the support rod, and both ends of the torsion spring are embedded in the inside of the clamping block.

[0013] Preferably, an embedding block is fixedly connected to an upper portion of one side of the clamp, a friction strip is fixedly connected to a middle portion of the clamp, and a groove is provided at a lower portion of the clamp.

[0014] Preferably, the interior of the protective box is fixedly connected with limiting blocks, and there are four limiting blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The utility model sets a clamp. When a problem occurs during cable production, the bidirectional threaded rod will rotate, and the bidirectional threaded rod drives the slide connected to the outer spiral to move, and the slide drives the clamp fixedly connected on one side of the upper part to move. The clamp will clamp the cable body set on one side to prevent the cable from continuing to rotate during production and to stop the device urgently. Then, the gear fixedly connected to the outer side of the bidirectional threaded rod will be clamped and locked by the block connected to the meshing teeth on the outer side of the gear, preventing the bidirectional threaded rod from reversing due to external force, which will cause the clamp to be unable to clamp the cable body, thereby improving the locking efficiency of the device.

[0017] 2. The utility model sets a warning light. When problems occur during cable production, the hydraulic rod fixed to the bottom surface of the protective box will quickly push the support plate upward, and the support plate will drive the workbench and its internal structure to move upward. When the warning light contacts the opening and closing door, it will alarm the staff, so that the staff can discover problems with the device in time and repair the device in time.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, the utility model provides an emergency stop device for cable mold production, including a workbench 1, the internal rotation of the workbench 1 is connected to a bidirectional threaded rod 2, the outer side of the bidirectional threaded rod 2 is spirally connected to a slide 3, there are two slides 3, one side of the upper part of the slide 3 is fixedly connected to a clamp 4, and each slide 3 has two clamps 4, a cable body 5 is provided on one side of the clamp 4, the outer side of the bidirectional threaded rod 2 is fixedly connected to a gear 6, the outer side of the gear 6 is meshingly connected to a clamp 7, the inner side of the clamp 7 is rotatably connected to a support rod 8 to fix the clamp 7.

[0027] Specifically, a support plate 9 is fitted on the bottom end of the workbench 1, and a hydraulic rod 10 is fixedly connected to the bottom end of the support plate 9. A protective box 11 is fixedly connected to the bottom end of the hydraulic rod 10, which can protect the workbench 1 and its internal parts to prevent them from being exposed to the external environment for a long time, which increases the probability of damage. The top of the protective box 11 is rotatably connected to an opening and closing door 12, and the top of the slide 3 is fixedly connected to a warning light 13.

[0028] Furthermore, one end of the bidirectional threaded rod 2 is fixedly connected to a servo motor 14, and the servo motor 14 is on the outside of the workbench 1. The servo motor 14 drives the bidirectional threaded rod 2 to rotate, and there is no need for manual rotation by the staff, thereby improving work efficiency and reducing the labor intensity of the staff.

[0029] Furthermore, a bearing 15 is provided on the outer side of the bidirectional threaded rod 2, and the bearing 15 is embedded in the inside of the workbench 1. Under the action of the bearing 15, the friction coefficient between the workbench 1 and the bidirectional threaded rod 2 is reduced, thereby ensuring the rotation accuracy of the bidirectional threaded rod 2 and reducing energy consumption.

[0030] It is worth noting that the bottom end of the slide 3 is fixedly connected to a guide block 16. There are two guide blocks 16, and the guide blocks 16 slide inside the workbench 1. Under the action of the guide blocks 16, the slide 3 is prevented from deflecting during movement, providing a guiding function for it.

[0031] It is worth noting that a torsion spring 17 is provided on the outer side of the support rod 8, and the two ends of the torsion spring 17 are embedded in the inside of the block 7. Under the action of the torsion spring 17, when the bidirectional threaded rod 2 drives the gear 6 to rotate forward, it pushes the block 7 to rotate outward. After stopping rotation, the torsion spring 17 drives the block 7 back to its original position and clamps the gear 6 to limit it.

[0032] It is worth mentioning that an embedding block 18 is fixedly connected to the upper part of one side of the clamp 4, a friction strip 20 is fixedly connected to the middle part of the clamp 4, and a groove 19 is provided at the lower part of the clamp 4. Under the action of the embedding block 18, the embedding block 18 will be embedded into the inside of the groove 19, thereby increasing the integrity of the two clamps 4 and increasing the clamping and locking effect. Under the action of the friction strip 20, the friction force of the clamp 4 on the surface of the cable body 5 will be increased, making it easier to clamp and fix it, thereby preventing relative sliding between the clamp 4 and the cable body 5.

[0033] It is worth emphasizing that the protective box 11 is internally fixedly connected with a limit block 21, and there are four limit blocks 21. Under the action of the limit block 21, the moving distance of the support plate 9 will be limited, so that the clamp 4 can accurately clamp the cable body 5.

[0034] Among them, the cable body 5, hydraulic rod 10, warning light 13 and servo motor 14 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0035] Working principle and process:

[0036] When a problem is encountered during cable production, the hydraulic rod 10 fixedly connected to the bottom surface of the protective box 11 will quickly push the support plate 9 upward, and the support plate 9 will drive the workbench 1 and its internal structure to move upward. Under the action of the limit block 21, the moving distance of the support plate 9 will be limited, so that the clamp 4 can accurately clamp the cable body 5. During the movement, the warning light 13 fixedly connected to the top of the slide 3 will alarm the staff when it contacts the opening and closing door 12, so that the staff can promptly discover problems with the device and repair the device in time. Then, the servo motor 14 drives the bidirectional threaded rod 2 to rotate, without the need for manual operation by the staff, thereby improving work efficiency and reducing the labor intensity of the staff. Under the action of the bearing 15, the friction coefficient between the workbench 1 and the bidirectional threaded rod 2 is reduced, ensuring the rotation accuracy of the bidirectional threaded rod 2 and reducing energy consumption. The bidirectional threaded rod 2 drives the slide 3 connected to the outer spiral to move, and under the action of the guide block 16, the slide 3 is prevented from deflecting during the movement. When the gear 5 is in the forward direction, the gear 5 is tightened and the locking device is stopped, so that the gear 5 and the cable body 5 can be tightened and the cable body 5 can be tightened.
