Description

Technical Field

[0001] The invention relates to the technical field of triangle iron processing, and in particular to an extrusion device for processing a triangle iron bracket of an air conditioner. Background Art

[0002] The air conditioning triangle iron (angle steel) bracket is an important component for supporting and fixing air conditioning equipment. Its processing requires high precision and high quality. The extrusion forming process of angle steel is usually carried out by placing the metal billet in the die of the extruder, applying high pressure to make it plastically deformed and extruding it through the die orifice to obtain the angle steel of the required cross-section. This process can ensure the dimensional accuracy and surface quality of the angle steel, reduce material waste and improve production efficiency.

[0003] For example, Chinese patent publication number CN220388599U discloses an extruder for processing the triangle iron of an air-conditioning bracket, which belongs to the field of triangle iron extruders and includes a base plate and a support plate. An extrusion molding box is arranged on one side of the upper surface of the base plate, and a discharge hole is provided at the output end of the extrusion molding box. Track rods are symmetrically arranged at one end of the extrusion molding box close to the discharge hole, and two track rods are respectively placed on both sides of the discharge hole. Cutting plates are slidably installed on the surfaces of the two track rods, and a V-shaped groove is provided on the lower side of the cutting plate, and the V-shaped groove corresponds to the discharge hole. A hydraulic cylinder is vertically arranged on the upper surface of one end of the base plate, and the output end of the hydraulic cylinder is fixedly installed on the cutting plate. A lifting support plate is arranged at the discharge port, and the support plate is raised before cutting to support the formed triangle iron. After cutting, the triangle iron falls onto the support plate, and the support plate is controlled to move downward. During the downward movement, the support plate is tilted to one side by a blocking column on one side.

[0004] The extruder can support the cut angle iron to prevent it from falling directly and causing damage. However, the angle iron is still in a high temperature state after being discharged from the extruder and has not yet been completely cooled and shaped. Size errors and uneven edges may occur during cutting, which requires subsequent processing. In actual situations, the angle iron is usually cut after being discharged from the extruder and transported for a certain distance. In addition, in order to ensure that the cutting component can better cut the angle iron, it is necessary to prevent the angle iron from shifting during the transportation process.

Since the travel direction of the driving slider is always in the horizontal direction, when the triangle iron deviates during the conveying process, the force exerted by the driving slider on the triangle iron will reset the triangle iron to ensure that the triangle iron is always conveyed along the predetermined route during the conveying process, so that it can stably and accurately enter the area where the cutting component is located, which can not only improve the cutting accuracy and efficiency, but also ensure that the cutting meets the specifications, reduce material waste and equipment wear, thereby optimizing the overall production process and ensuring the high quality and consistency of the product.

DETAILED DESCRIPTION

[0032] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8The present invention provides a technical solution: an extrusion device for processing an air conditioner triangle bracket, comprising a conveying frame 2 fixedly mounted on the top of a bottom plate 1, and a cutting assembly 3 fixedly mounted on the top of the conveying frame 2, characterized in that: a through square groove 7 is opened on the top of the conveying frame 2, a guide part is slidably mounted on the inner wall of the square groove 7, the guide part is two driving sliders 10, two traction frames 13 are rotatably mounted on the top of the driving slider 10, and a clamping part is provided on one end of the two traction frames 13 close to the triangle 6;

[0034] It also includes a driving assembly that enables the two driving sliders 10 to move back and forth relative to each other;

[0035] It also includes a clamping assembly arranged on the driving slider 10. When the driving slider 10 moves in a direction away from the extruder 4, the clamping assembly can rotate the traction frame 13 and clamp the triangle iron 6; when the driving slider 10 moves in a direction close to the extruder 4, the clamping assembly can rotate the traction frame 13 and release the pressure on the triangle iron 6.

[0036] See also Figure 1 as well as Figure 4 When the device is used, the metal billet is extruded through the extruder 4 to form a triangle iron 6 of the required cross-section. The triangle iron 6 discharged from the discharge port of the extruder 4 will gradually move toward the cutting component 3, so that the triangle iron 6 of the required length is cut through the cutting component 3 to facilitate subsequent drilling and assembly. In the process of the triangle iron 6 being discharged from the extruder 4 and transported to the area where the cutting component 3 is located, the triangle iron 6 is naturally cooled to avoid deformation of the material under high temperature, making its shape more stable, ensuring the dimensional accuracy and edge quality of the triangle iron 6 during cutting, and improving the quality of the final product.

[0037] In the process of conveying the triangle iron 6 from the discharge port of the extruder 4 to the cutting component 3 area, improper parameters such as the operating speed and pressure of the extruder 4 will also affect the conveying state of the material, which may cause the triangle iron 6 to deviate during the conveying process, and external factors such as vibration and impact around the machine may also cause the triangle iron 6 to deviate, thereby causing the triangle iron 6 to fail to accurately enter the cutting position, resulting in errors in the cutting size, and the deviation may cause the triangle iron 6 to fall off or get stuck in the equipment during the conveying process, bringing safety hazards. Therefore, this embodiment mainly solves the problem of the deviation of the triangle iron 6, and the specific implementation method is as follows:

[0038] In the process of conveying the triangle iron 6 to the cutting component 3 area, the two driving sliders 10 make relative reciprocating movements through the driving assembly, and when the driving slider 10 moves away from the extruder 4, the clamping assembly causes the clamping parts on the corresponding two traction frames 13 to clamp the triangle iron 6. When the driving slider 10 moves toward the extruder 4, the pressure on the triangle iron 6 is released through the clamping assembly, and the triangle iron 6 is moved and reset to prevent friction between the clamping part and the triangle iron 6, so as to protect the triangle iron 6 and the clamping part.

[0039] The reciprocating movement ensures that there is always a pair of traction frames 13 to clamp the triangle iron 6 and pull it during the transportation of the triangle iron 6 toward the cutting component 3, preventing the triangle iron 6 from shifting during the transportation process, ensuring that the cutting tool applies force at the correct position, avoiding uneven edges or burrs, reducing equipment wear and damage caused by deviation, reducing equipment maintenance and replacement costs, and increasing the service life of production equipment.

[0040] Furthermore, sliding blocks 14 are slidably mounted on the inner walls of the upper and lower sides of the traction frame 13, and elastic telescopic rods 23 are installed between the two sliding blocks 14 and the inner wall of the traction frame 13 away from the triangle iron 6, and a rotating rod 15 is rotatably mounted between the two sliding blocks 14, and a squeezing ball 16 is fixedly mounted on the outer wall of the rotating rod 15, and the squeezing ball 16 forms a clamping portion;

[0041] It also includes a limiting component that allows the rotating rod 15 to rotate only when it moves in a direction close to the extruder 4.

[0042] See also Figure 5 The clamping part is a squeezing ball 16. When the driving slider 10 moves in a direction away from the extruder 4, the two traction frames 13 are brought close to each other through the clamping assembly, so that the elastic telescopic rod 23 is continuously squeezed. When the elastic telescopic rod 23 is compressed to a certain extent, the elastic force inside it has been completely released, and the elastic telescopic rod 23 no longer has room for further compression. At this time, the elastic telescopic rod 23 exhibits a rigid state and no longer has elastic deformation ability, but is similar to a rigid connecting rod of a fixed length, so that the two squeezing balls 16 clamp the triangle iron 6, and lock the rotating rod 15 through the limit assembly to prevent it from rotating. Since the traveling direction of the driving slider 10 is always horizontal, when the triangle iron 6 deviates during the conveying process, the force of the squeezing ball 16 on the triangle iron 6 will reset the triangle iron 6 to ensure that the triangle iron 6 is always conveyed along the predetermined route during the conveying process, so that it can stably and accurately enter the area where the cutting component 3 is located, which can not only improve the cutting accuracy and efficiency, but also ensure that the cutting meets the specifications, reduce the waste of materials and the wear of equipment, thereby optimizing the overall production process and ensuring the high quality and consistency of the product.

[0043] When the driving slider 10 moves to reset in the direction close to the extruder 4, the limiting effect of the rotating rod 15 is released through the limit, so that the rotating rod 15 can rotate, and the pressure of the traction frame 13 on the elastic telescopic rod 23 is reduced through the clamping assembly, so that the elastic potential energy of the elastic telescopic rod 23 is restored to a certain extent. At this time, the elastic telescopic rod 23 is still in a compressed state, so that the squeezing ball 16 still has a pressure effect on the triangle iron 6. When the driving slider 10 moves in the direction close to the extruder 4, the squeezing ball 16 and the extruder 4 are relatively displaced, so that the squeezing ball 16 rotates and moves to reset, thereby reducing the friction between the squeezing ball 16 and the triangle iron 6.

[0044] It is worth mentioning that the moving speed of the driving slider 10 is consistent with the conveying speed of the triangle iron 6, which reduces the relative movement between mechanical parts, reduces the friction between the squeezing ball 16 and the triangle iron 6, extends the service life of the device, and reduces maintenance and replacement costs.

[0045] Furthermore, the limiting assembly includes a ratchet 24 fixedly mounted on the outer wall of the rotating rod 15, a cavity is provided inside the sliding block 14, and a plurality of pawls 25 cooperating with the ratchet 24 are rotatably mounted on the inner wall of the cavity, and a torsion spring is installed between the rotating shaft of the pawl 25 and the inner wall of the sliding block 14.

[0046] See also Figure 5 as well as Figure 7 When the driving slider 10 moves toward the direction close to the extruder 4 to reset, the curved surface of the pawl 25 will contact the inclined surface of the ratchet 24, so that the pawl 25 rotates toward the inner wall of the sliding block 14, thereby driving the rotating rod 15 and the squeezing ball 16 to rotate, so as to reduce the friction between the squeezing ball 16 and the triangle iron 6 during the reset process of the driving slider 10, and when the ratchet teeth of the pawl 25 and the ratchet 24 are disengaged, they reset themselves through the torsion spring.

[0047] When the driving slider 10 moves in the direction away from the extruder 4, the tip of the pawl 25 will contact and abut against the direct surface of the ratchet 24 and, under the limiting action of the sliding block 14, prevent the ratchet 24 from rotating, thereby preventing the rotating rod 15 and the squeezing ball 16 from rotating, thereby completing the limiting action, so that when the driving slider 10 moves in the direction away from the extruder 4, the two squeezing balls 16 can clamp and pull the triangle iron 6, and can reset the triangle iron 6 when it is offset.

[0048] Further, the clamping assembly includes a rotating groove 21 opened on the driving slider 10 near the top of the traction frame 13, and a rotating plate 20 is rotatably installed on the inner wall of the rotating groove 21. The rotating plate 20 is a curved plate, and one end of the rotating plate 20 is rotatably connected to the outer wall of the traction frame 13 through a sliding groove pin structure. A cavity is opened in the driving slider 10, and a notch is opened in the cavity near the inner wall of the square groove 7. A second straight groove 9 is opened on the inner wall of the square groove 7, and the notch opened in the cavity of the driving slider 10 corresponds to the second straight groove 9. The driving slider 10 A limit block 17 is slidably installed at the bottom of the slot, and a protrusion 8 is fixedly installed on the outer wall of the limit block 17. The protrusion 8 slides in the cavity slot and the second straight slot 9 in the driving slider 10, and the damping of the protrusion 8 and the second straight slot 9 is greater than the damping of the limit block 17 and the bottom of the driving slider 10. A limit slot 18 is provided on the top of the limit block 17, and the inner wall of the limit slot 18 away from the protrusion 8 is composed of two planes and an inclined surface in the middle. A limit ball 22 is rotatably installed on the outer wall of the bottom of the rotating plate 20, and the limit ball 22 can fit with the inner wall of the limit slot 18;

[0049] The clamping assembly further comprises a torsion spring installed between the rotating shaft of the traction frame 13 and the shaft seat.

[0050] See also Figure 5 When the driving slider 10 moves away from the extruder 4, the driving slider 10 slides in the square groove 7. Since the damping between the limit block 17 and the bottom of the cavity of the driving slider 10 is relatively large, the limit block 17 and the driving slider 10 will be relatively displaced in the initial stage, that is, the limit block 17 and the second straight groove 9 remain stationary until the driving slider 10 contacts and abuts against the protrusion 8. Figure 6 In this process, the stop block 17 will move to the right until the left straight groove fits with the stop ball 22. Figure 5 Taking the left rotating plate 20 as an example, the limiting ball 22 and the rotating plate 20 will rotate clockwise, so that the traction frame 13 moves toward the direction of the triangle iron 6, and then the elastic telescopic rod 23 is compressed to the limit state, so that the extrusion ball 16 and the triangle iron 6 are closely fitted, thereby guiding the triangle iron 6 to be transported to the cutting component 3 along a precise route;

[0051] Consistent with the above principle, when the driving slider 10 moves toward the extruder 4, the limit block 17 will drive the rotating plate 20 to move away from the triangle iron 6, thereby releasing the pressure of the rotating plate 20 on the traction frame 13 to release the elastic potential energy in the elastic telescopic rod 23. Under the cooperation of the ratchet 24 and the pawl 25, the rotating rod 15 can rotate when moving toward the extruder 4, so as to facilitate the resetting of the driving slider 10.

[0052] It is worth noting that the slide pin structure is specifically a slide slot opened on the outer wall of the traction frame 13, and a pin is slidably installed in the slide slot, and the pin is rotatably connected to the rotating plate 20. Through this cooperation, the rotating plate 20 can avoid interference in the travel caused by the rotation.

[0053] Furthermore, the driving assembly includes driving rods 11 which are respectively installed on the outer walls of both sides of the conveying frame 2 and can rotate. The two driving rods 11 have driven rods 12 rotatably installed on the opposite ends. The other ends of the two driven rods 12 are respectively rotatably connected to the outer walls of the corresponding driving sliders 10, and the projections of the driving rods 11 and the driven rods 12 on both sides are centrally symmetrically arranged along the rotation axis.

[0054] See also Figure 2 The two driving rods 11 are driven to rotate by an external motor, thereby causing the two driven rods 12 to rotate. During the rotation of the driven rods 12, the corresponding driving sliders 10 are driven to move back and forth. The projections of the two pairs of driving rods 11 and the driven rods 12 are symmetrical along the axis center, which can ensure that the two driving sliders 10 can always maintain a mirror state, ensuring that there is always a pair of squeezing balls 16 to guide the triangle iron 6, so as to reduce the probability of offset.

[0055] Furthermore, the elastic telescopic rod 23 includes a sleeve 26 slidably mounted on the inner wall of the traction frame 13, a moving rod 27 is slidably mounted on the inner wall of the sleeve 26, and a spring 28 is installed between the moving rod 27 and the inner wall of the sleeve 26, a fixing ring 30 is fixedly mounted on the inner wall of the sleeve 26, and a contact piece 29 is fixedly mounted on the outer wall of one end of the moving rod 27 extending into the sleeve 26;

[0056] Two cylinders 31 are fixedly mounted on the outer wall of the traction frame 13 . The output ends of the two cylinders 31 are fixedly connected to the corresponding sleeves 26 , respectively, and the cylinders 31 are electrically connected to the contact pieces 29 .

[0057] As can be seen from the above, when the driving slider 10 moves in the direction close to the extruder 4, the torsion spring between the rotating shaft of the traction frame 13 and the shaft seat will continuously cause the traction frame 13 to be subjected to torsional force to ensure that the extrusion ball 16 always keeps in close contact with the triangle iron 6. Under the cooperation of the ratchet 24 and the pawl 25, the rotating rod 15 can rotate when moving in the direction close to the extruder 4. When the triangle iron 6 deviates at this time, the extrusion force of the triangle iron 6 on the extrusion ball 16 will cause the sliding block 14 to move away from the triangle iron 6, thereby causing the moving rod 27 to move in the direction close to the spring 28. At this time, the contact piece 29 contacts the fixing ring 30, triggering the cylinder 31. The output end of the cylinder 31 will extend to further squeeze the spring 28 until it reaches the limit state, thereby making the extrusion ball 16 and the triangle iron 6 fit tightly again, and correcting it during the relative movement of the extrusion ball 16 and the triangle iron 6.

[0058] It is worth mentioning that the contact piece 29 can also be connected to an external alarm. When the contact piece 29 contacts the fixing ring 30 during the process of driving the slider 10 to reset, an alarm is issued in time to notify the staff to check the equipment and prevent the situation from further deteriorating.

[0059] It is worth noting that the damping between the protrusion 8 and the second straight groove 9 will inevitably decrease. When the staff finds that the triangle iron 6 is offset and there is no self-repair or alarm, they should check this place first.

[0060] Furthermore, a plurality of transmission rollers 5 are rotatably mounted on the inner wall of the square groove 7 close to the extruder 4, and the transmission rollers 5 are driven to rotate by an external driving assembly.

[0061] See also Figure 3 A number of transmission rollers 5 are rotatably installed on the inner wall of the square groove 7. The outer wall of the transmission roller 5 is driven by a transmission wheel and a conveyor belt to provide power during the transportation of the triangle iron 6. When the triangle iron 6 does not deviate, the friction between the triangle iron 6 and the extrusion ball 16 is further reduced to extend the service life of the extrusion ball 16 and save resources.

[0062] Furthermore, a groove corresponding to the bottom of the wing plates on both sides of the triangle iron 6 is formed on the top of the driving slider 10 .

[0063] Furthermore, the conveying plane of the driving roller 5 is flush with the plane of the groove of the driving slider 10 , and both are at the height of the bottom end of the triangle iron 6 when the extruder 4 discharges the triangle iron 6 .

[0064] See also Figure 4 A groove is formed on the top of the driving slider 10, which is aligned with the bottom of the two side wing plates of the triangle iron 6. During the transportation of the triangle iron 6, the two side wing plates can be embedded in the groove, further reducing the probability of the triangle iron 6 being offset. In addition, the bottom of the groove of the driving slider 10, the highest end of the transmission roller 5 and the bottom of the wing plate of the triangle iron 6 are on the same horizontal line to ensure the normal operation of the equipment.

[0065] Furthermore, the length of the driven rod 12 is greater than the length of the driving rod 11 .

[0066] See also Figure 2 The driven rod 12 is longer than the driving rod 11 , which can ensure that when the two driving rods 11 and the two driven rods 12 are simultaneously horizontal, the two driving sliders 10 will not collide with each other, and the two driving sliders 10 will not interfere with the rotating shaft between the two driving rods 11 .

[0067] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
