Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, specifically to an extrusion die for processing aluminum alloy profiles. Background Technology

[0002] Aluminum alloys are lightweight, high-strength, and corrosion-resistant, and have a wide range of applications. Common fields may include transportation, such as automobiles and airplanes, to reduce weight; the construction industry, as structural materials for doors, windows, and curtain walls; electronic devices, such as the casings of mobile phones and computers, because of their good heat dissipation; packaging materials, such as aluminum cans, which may also be made of aluminum alloys; and in machinery manufacturing or aerospace, they may be used for parts.

[0003] Application number CN202223128867.4 discloses a cold extrusion die for aluminum alloy profiles, relating to the field of cold extrusion technology for aluminum alloy profiles. This cold extrusion die for aluminum alloy profiles includes a mounting plate, a fixing mechanism, and mounting components. A mounting bracket is mounted on the top of the mounting plate. The fixing mechanism is located on the top of the mounting plate and includes a placement bracket, a fixing plate, and sliders. The placement bracket has a slot on its inner side, and two sets of sliders are arranged in the slot. A fixing plate is installed between the two sets of sliders. This cold extrusion die for aluminum alloy profiles can fix the outer sides of the first and second dies by placing a fixing rod in the opening and setting the first and second dies in the placement bracket, preventing positional displacement of the first and second dies during processing. It can also control the start of the cylinder by placing aluminum alloy on the inner side of the placement plate, ensuring that the outer side of the mounting box fits against the outer side of the second die.

[0004] During use, the mold is fixed by a placement frame, and the mounting block is fixed to the position of the stamping part. When unloading the material, it is necessary to completely disassemble or manually adjust the position, which is time-consuming and easily damages the mold. In addition, the clamping force of ordinary molds is not adjustable and is only fixed by bolts. It is easy for the positioning to be offset due to material deformation, and repeated adjustments are required. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum alloy profile extrusion die to solve the problem of efficient loading and unloading of blanks.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an aluminum alloy profile extrusion die, comprising an extrusion assembly, an installation assembly, and a fixing assembly. The installation assembly and fixing assembly are installed on the bottom outer wall of the extrusion assembly, and the fixing assembly is fixed on the top two outer walls of the installation assembly. The extrusion assembly includes a base plate, and fixing members and fasteners are respectively fixed on the top two inner walls of the base plate. The fasteners are located outside the fixing members, and movable frames are installed at the top of the fasteners. Clamping blocks are provided at the close ends of the two movable frames. A sliding groove is formed on the upper surface of the movable frame, and the fixing member is slidably connected to the inner wall of the sliding groove. A compression spring is sleeved on the outside of the fixing member, and the compression spring is located between the movable frame and the base plate. The purpose of this setup is that, during the use of the mold, the aluminum alloy blank is placed in the placement slot of the mounting block. The position of the linkage plate is adjusted by the slide rail, so that the clamping block clamps both sides of the linkage plate under the action of the compression spring, completing the initial fixation of the blank. The cylinder drives the stamping block to press down, contacting the blank in the placement slot. The pressure causes the aluminum alloy to plastically deform in the slot, forming the target profile outline. After stamping, the cylinder retracts the stamping block, and the clamping block releases the linkage plate under the elastic restoring force of the compression spring. At the same time, the tension spring pulls the mounting block back to its initial position along the slide rail, facilitating the removal of the finished product and preparation for the next cycle. The slide rail and the slider form a linear sliding pair, ensuring the stability of the linkage plate's movement trajectory. During stamping, the linkage plate is subjected to the pressure of the clamping block. The slide block remains stationary. During resetting, the slider slides along the slide rail, assisting the linkage plate in returning to its original position. The mounting block is connected to the fixing pins via tension springs at both ends. After stamping, the tension springs' contraction force pulls the mounting block back to its initial position. The overlapping design of the placement groove and the stamping block ensures precise alignment of the profile processing position after resetting. The slide rail and the slider form a low-friction linear sliding pair. After stamping, the linkage plate can quickly slide back to its initial position along the slide rail, reducing resetting time. The rigid support of the slider ensures stable movement trajectory of the linkage plate, avoiding secondary adjustments caused by offset. The tension springs are connected to the mounting block via fixing pins. After stamping, the tension springs' contraction force directly acts on the mounting block, causing it to quickly reset to the preset position, enhancing the processing efficiency of the mold.

[0008] Furthermore, the upper surface of the base plate is provided with a set of slide rails, and a slider is slidably connected to the outer wall of the set of slide rails. A linkage plate is installed on the upper surface of the slider, and two clamping blocks abut against the top two outer walls of the linkage plate. The purpose of this arrangement is that during the use of the mold, the slide rails and sliders form a low-friction linear sliding pair. After stamping, the linkage plate can quickly slide back to its initial position along the slide rails, reducing the reset time. The rigid support of the slider ensures the stability of the linkage plate's movement trajectory and avoids secondary adjustments caused by deviation.

[0009] Furthermore, a mounting block is provided on the top side of the linkage plate away from the clamping block, and a placement groove is formed on the upper surface of the mounting block. The purpose of this arrangement is that, during the use of the mold, the overlapping design of the placement groove and the stamping block ensures that the profile processing position is accurately aligned after resetting.

[0010] Furthermore, fixing pins are installed on the outer walls of the base plate near the top two sides of the mounting block. Tension springs are sleeved on the inner walls of the top ends of the two fixing pins, and the other ends of the two tension springs are fixedly sleeved on the inner walls of both ends of the mounting block. The purpose of this arrangement is that during the use of the mold, when resetting, the slider slides along the slide rail, assisting the linkage plate to return to its original position. The mounting block is connected to the fixing pins through the tension springs at both ends. After stamping, the contraction force of the tension springs pulls the mounting block back to its initial position.

[0011] Furthermore, a support seat is provided on the outer wall of the base plate near the top of the mounting block. A cylinder is mounted on the top outer wall of the support seat, and a stamping block is mounted on the shaft end of the cylinder. The purpose of this arrangement is that during the use of the mold, the cylinder drives the stamping block to press down, contacting the blank in the placement groove. The pressure causes the aluminum alloy to plastically deform in the groove, forming the target profile outline. After stamping is completed, the cylinder retracts the stamping block.

[0012] Furthermore, the stamping block is placed on the top inner wall of the support base, and the stamping block coincides with the placement groove. The purpose of this arrangement is that, during the use of the mold, the overlapping design of the placement groove and the stamping block ensures that the blank placement position is accurately aligned after resetting, reducing manual calibration time.

[0013] This utility model has the following beneficial effects:

[0014] (1) By setting up clamping blocks and compression springs, the position of the linkage plate is adjusted by the slide rail, so that the clamping blocks clamp the two sides of the linkage plate under the action of the compression spring, thus completing the initial fixing of the blank. The clamping blocks release the linkage plate under the elastic restoring force of the compression spring, and at the same time, the tension spring pulls the mounting block to reset to the initial position along the slide rail, which is convenient for taking out the finished product and preparing for the next cycle, thus enhancing the processing efficiency of the mold.

[0015] (2) In this utility model, by setting up a slider, a tension spring and a linkage plate, the linkage plate is kept stationary by the pressure of the clamping block during stamping; during resetting, the slider slides along the slide rail to assist the linkage plate in returning to its position, and the mounting block is connected to the fixing pin through tension springs at both ends. After stamping, the tension spring contraction force pulls the mounting block back to the initial position.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The fixing member 303 is slidably connected to the inner wall of the sliding groove 306. A compression spring 307 is sleeved on the outside of the fixing member 303. The compression spring 307 is located between the movable frame 304 and the base plate 101. The purpose of this setup is that, during the use of the mold, the aluminum alloy blank is placed in the placement groove 202 of the mounting block 201. The position of the linkage plate 203 is adjusted by the slide rail 204, so that the clamping block 305 clamps both sides of the linkage plate under the action of the compression spring 307, completing the initial fixing of the blank. The cylinder 103 drives the stamping block 104 to press down, contacting the blank in the placement groove 202. The pressure causes the aluminum alloy to plastically deform in the groove, forming the target profile outline. After stamping, the cylinder 103 retracts the stamping block 104, and the clamping block 305 releases the linkage plate 203 under the elastic restoring force of the compression spring 307. At the same time, the tension spring 302 pulls the mounting block 201 back to its initial position along the slide rail 204, facilitating the removal of the finished product and preparation for the next cycle. The slide rail 204 and the slider 205 form a linear sliding pair, ensuring the stability of the movement trajectory of the linkage plate 203. During stamping, the linkage plate 203... 3. The clamping block 305 keeps the block stationary under pressure. During resetting, the slider 205 slides along the slide rail 204, the auxiliary linkage plate 203 returns to its original position, and the mounting block 201 is connected to the fixing pin 301 through the tension springs 302 at both ends. After stamping, the tension springs pull the mounting block 201 back to the initial position. The overlapping design of the placement groove 202 and the stamping block 104 ensures that the profile processing position is accurately aligned after resetting. The slide rail 204 and the slider 205 form a low-friction linear sliding pair. After stamping, the linkage plate 203 can quickly slide back to the initial position along the slide rail, reducing the resetting time. The rigid support of the slider 205 ensures the stability of the linkage plate's movement trajectory and avoids secondary adjustments caused by deviation. The tension spring 302 is connected to the mounting block 201 through the fixing pin 301. After stamping, the tension springs directly act on the mounting block, causing it to quickly reset to the preset position, thus enhancing the processing efficiency of the mold.

[0026] The upper surface of the base plate 101 is provided with a set of slide rails 204. A slider 205 is slidably connected to the outer wall of the slide rails 204. A linkage plate 203 is installed on the upper surface of the slider 205. Two clamping blocks 305 abut against the top two outer walls of the linkage plate 203. The purpose of this arrangement is that during the use of the mold, the slide rails 204 and the slider 205 form a low-friction linear sliding pair. After stamping, the linkage plate 203 can quickly slide back to its initial position along the slide rails, reducing the reset time. The rigid support of the slider 205 ensures the stability of the linkage plate's movement trajectory and avoids secondary adjustments caused by deviation.

A cylinder 103 is mounted on the top outer wall of the support base 102, and a stamping block 104 is mounted on the shaft end of the cylinder 103. The purpose of this arrangement is that during the use of the mold, the cylinder 103 drives the stamping block 104 to press down and contact the blank in the placement groove 202.

The pressure causes the aluminum alloy to plastically deform in the groove, forming the target profile outline. After stamping, the cylinder 103 retracts the stamping block 104, and the clamping block 305 releases the linkage plate 203 under the elastic restoring force of the compression spring 307. At the same time, the tension spring 302 pulls the mounting block 201 back to the initial position along the slide rail 204, making it easy to remove the finished product and prepare for the next cycle.
