A protective device for aluminum profiles without extrusion.

Abstract

This utility model relates to the field of aluminum profile technology, specifically a protective device for aluminum profile extrusion without a die. It includes a base plate and support columns. Support columns are symmetrically arranged at the lower end of the base plate, and support blocks are symmetrically connected to the upper end of the base plate. A clamping mechanism is connected to the support blocks, and an auxiliary extrusion mechanism is connected to the clamping mechanism. The auxiliary extrusion mechanism is located above the base plate, and a monitoring mechanism is provided at the upper end of the base plate. This utility model includes a monitoring mechanism. During the mold's downward movement, the sliding plate is extruded. When the mold depresses excessively, the limiting column fails to limit the sliding plate, causing it to break. The sliding plate then continues to press down, extruding the slider and the return spring. Simultaneously, the reaction force of the support spring and the return spring buffers the sliding plate. When the slider presses against a switch during its downward movement, the switch triggers an alarm device to remind the operator that excessive extrusion requires immediate attention.

Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and in particular to a protective device for aluminum profiles without extrusion. Background Technology

[0002] During the processing of aluminum profiles, extrusion protection devices are usually used. These devices protect the mold and extrusion equipment during the extrusion process, preventing the "no cake" phenomenon caused by mold misalignment, damage, or abnormalities, which means that a complete profile is not formed.

[0003] Existing protective devices for cakeless extrusion cannot promptly alert operators when the device is over-extruded, leading to mold damage and reducing the overall usability of the device.

[0004] Therefore, in response to the problem that existing protective devices for non-cake extrusion cannot promptly alert operators when the device is over-extruded, leading to mold damage during over-extrusion, this utility model is equipped with a monitoring mechanism. During use, when over-extrusion occurs, the monitoring mechanism triggers an alarm device to alert the operator, thereby preventing mold damage and improving the overall usability of the device. Utility Model Content

[0005] To overcome the common problem that protective devices for non-cake extrusion cannot promptly alert operators when the device is over-extruded, thus damaging the mold in the event of over-extrusion.

[0006] The technical solution of this utility model is as follows: a protective device for aluminum profile extrusion without a biscuit, comprising a base plate and support columns. The support columns are symmetrically arranged at the lower end of the base plate, and support blocks are symmetrically connected to the upper end of the base plate. The support blocks are connected to a clamping mechanism, and the clamping mechanism is connected to an auxiliary extrusion mechanism. The auxiliary extrusion mechanism is arranged above the base plate, and a monitoring mechanism is arranged at the upper end of the base plate.

[0007] Preferably, the clamping mechanism includes a drive motor, a threaded rod, a slide rod, and clamping plates. The drive motor is provided on the side of the support block, the output shaft of the drive motor is connected to the threaded rod, the slide rod is provided between the two support blocks, and two clamping plates are connected to the side of the threaded rod by reverse threads.

[0008] Preferably, the threaded rod is rotatably connected to the support block, the clamp is slidably connected to the slide rod, and the clamp is disposed between the two support blocks.

[0009] Preferably, the auxiliary extrusion mechanism includes a slot, a rotating rod, and a connecting roller. The slot is provided on the side of the clamping plate, and the rotating rod is symmetrically rotatably connected to the inside of the slot. The connecting roller is provided on the side of the rotating rod.

[0010] Preferably, the monitoring mechanism includes a chute, a slide plate, a housing, a slider, a support spring, a switch, a reset spring, and a limiting post. The upper end of the base plate has a chute, and a slide plate is slidably connected to the inner side of the chute. The housing is symmetrically arranged at the bottom end of the chute, and a slider is slidably connected to the upper end of the housing. A support spring is arranged inside the housing. A switch is arranged at the bottom end of the chute, and a reset spring is arranged on the side of the switch. A limiting post is slidably connected to the side of the base plate, and the end of the limiting post is located below the slide plate.

[0011] Preferably, one end of the support spring is connected to the inner bottom surface of the housing, the other end of the support spring is connected to the bottom surface of the slider, one end of the reset spring is connected to the inner bottom surface of the slide groove, and the other end of the reset spring is connected to the bottom surface of the slide plate.

[0012] The beneficial effects of this utility model are: 1. An auxiliary extrusion mechanism is provided. After the mold is clamped, it is extruded by the extrusion device. During the extrusion process, the mold slides down. At the same time, the mold drives the connecting roller to rotate around the rotating rod as the center during the slide, thereby buffering the mold slide and avoiding damage caused by friction on the side wall during the descent. 2. A monitoring mechanism is installed. During the mold's downward movement, the sliding plate is squeezed. When the mold is pressed down excessively, the limiting post cannot limit the sliding plate. At this time, the limiting post is damaged, and the sliding plate continues to press down and squeeze the slider and the return spring. At the same time, the sliding plate is buffered by the reaction force of the support spring and the return spring. When the slider squeezes the switch during the downward movement, the alarm device is triggered by the switch to remind the operator that the squeezing is excessive and needs to be dealt with in time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 This utility model provides a technical solution: a protective device for aluminum profile extrusion without a biscuit, including a base plate 1 and a support column 2. The support column 2 is symmetrically arranged at the lower end of the base plate 1, and the support block 3 is symmetrically connected to the upper end of the base plate 1. The support block 3 is connected to a clamping mechanism 4, and the clamping mechanism 4 is connected to an auxiliary extrusion mechanism 5. The auxiliary extrusion mechanism 5 is arranged above the base plate 1, and a monitoring mechanism 6 is arranged at the upper end of the base plate 1.

[0017] The clamping mechanism 4 includes a drive motor 41, a threaded rod 42, a slide rod 43, and a clamping plate 44. The drive motor 41 is located on the side of the support block 3. The output shaft of the drive motor 41 is connected to the threaded rod 42. The slide rod 43 is located between the two support blocks 3. The threaded rod 42 is connected to two clamping plates 44 by reverse threads on its side. The threaded rod 42 is rotatably connected to the support block 3, and the clamping plate 44 is slidably connected to the slide rod 43. The clamping plate 44 is located between the two support blocks 3. The mold to be extruded is placed between the two clamping plates 44. Then, the drive motor 41 is started to drive the threaded rod 42 to rotate. During the rotation, the threaded rod 42 drives the clamping plate 44 to slide on the side of the slide rod 43. At the same time, the clamping plate 44 is clamped during the movement of the clamping plate 44.

[0018] The auxiliary extrusion mechanism 5 includes a slot 51, a rotating rod 52, and a connecting roller 53. The slot 51 is provided on the side of the clamping plate 44. The rotating rod 52 is symmetrically rotatably connected to the inside of the slot 51. The connecting roller 53 is provided on the side of the rotating rod 52. After clamping, the extrusion device performs extrusion. During the extrusion process, the mold slides down. At the same time, the mold drives the connecting roller 53 to rotate around the rotating rod 52 as the center during the downward movement, thereby buffering the downward movement of the mold.

[0019] The monitoring mechanism 6 includes a slide 61, a slide plate 62, a housing 63, a slider 64, a support spring 65, a switch 66, a reset spring 67, and a limiting post 68. A slide 61 is provided on the upper end of the base plate 1. The slide plate 62 is slidably connected to the inner side of the slide 61. The housing 63 is symmetrically arranged at the bottom inside the slide 61. The slider 64 is slidably connected to the upper end of the housing 63. A support spring 65 is installed inside the housing 63. A switch 66 is installed at the bottom inside the slide 61. A reset spring 67 is installed on the side of the switch 66. A limiting post 68 is slidably connected to the side of the base plate 1. The end of the limiting post 68 is located below the slide plate 62. One end of the support spring 65 is connected to the inner bottom surface of the housing 63. The other end is connected to the bottom surface of the slider 64. One end of the return spring 67 is connected to the bottom surface inside the slide groove 61, and the other end of the return spring 67 is connected to the bottom surface of the slide plate 62. During the downward movement of the mold, the slide plate 62 is squeezed. When the mold is pressed down excessively, the limit post 68 can no longer limit the slide plate 62, and the limit post 68 is destroyed. Then the slide plate 62 is pressed down and squeezes the slider 64 and the return spring 67. During the downward movement, the slider 64 squeezes the support spring 65. At the same time, the reaction force of the support spring 65 and the return spring 67 buffers the slide plate 62. When the slider 64 squeezes the switch 66 during the downward movement, the switch 66 triggers the alarm device to remind the operator to squeeze too much.

[0020] Working principle: According to Figures 1 to 2 First, place the mold to be extruded between two clamping plates 44. Then, start the drive motor 41 to drive the threaded rod 42 to rotate. During the rotation, the threaded rod 42 drives the clamping plate 44 to slide on the side of the slide rod 43. At the same time, the clamping plate 44 is clamped during the movement of the clamping plate 44. according to Figures 3 to 4 After clamping, the die is squeezed by the extrusion device. During the extrusion process, the die slides down and at the same time, the die drives the connecting roller 53 to rotate around the rotating rod 52 as the center, thereby buffering the die slide and avoiding damage caused by die friction. according to Figures 5 to 6 During the downward movement of the mold, the sliding plate 62 is squeezed. When the mold is pressed down excessively, the limiting post 68 can no longer limit the sliding plate 62 and is damaged. Then the sliding plate 62 presses down and squeezes the slider 64 and the return spring 67. During the downward movement, the slider 64 squeezes the support spring 65. At the same time, the reaction force of the support spring 65 and the return spring 67 buffers the sliding plate 62. When the slider 64 squeezes the switch 66 during the downward movement, the switch 66 triggers the alarm device to remind the operator to squeeze too much. In this device, the drive motor 41 is started after being connected to an external power source via a power cord. The drive motor 41 is a known and existing technology on the market and will not be described in detail here.
