Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to an aluminum strip riveting mechanism. Background Art

[0002] When the aluminum strip is unrolled and unloaded, after the unloading of the previous aluminum coil is completed, the aluminum strip head of the next aluminum coil needs to be put back into the traction equipment to continue unloading. In order to increase the unloading speed of the aluminum coil, the end of the previous aluminum coil is usually riveted to the head end of the next aluminum coil as a whole. In this way, the aluminum strip only needs to be put into the traction equipment once, avoiding the problem of putting the aluminum strip into the traction equipment once for each new aluminum coil opened.

[0003] At present, the riveting of the front and rear aluminum strip ends is done manually. There are two problems in manual operation: 1. It takes a lot of time to punch holes and rivet manually. The time spent on the whole process is basically the same as the time to put the aluminum strip back into the traction equipment. Therefore, this riveting method is inefficient;

[0004] 2. The quality of manual riveting is determined by the worker's skill level. There are many uncontrollable factors, so the quality of riveting cannot be guaranteed.

[0005] Therefore, there is an urgent need for an aluminum strip riveting mechanism to improve the quality and efficiency of aluminum strip riveting. Utility Model Content

[0009] The clamping unit comprises a slide table, a slide rail is provided on the slide table, a slider is slidably provided on the slide rail, a sliding seat is provided at one end of the slider away from the slide rail, the sliding seat is sleeved on the periphery of the slide table, two supporting blocks are symmetrically provided at one end of the sliding seat close to the ejector pin, a riveting table is provided between the two supporting blocks, and a riveting protrusion is provided on the riveting table;

[0010] A second driving device is provided at one end of the sliding seat away from the supporting block, and a pressing arm is provided at the output end of the second driving device, and the pressing arm is used to press the aluminum strip on the supporting block;

[0011] A mounting plate is provided at one end of the slide, a third driving device is provided at one side of the mounting plate close to the clamping unit, and an output end of the third driving device is connected to a nearby supporting block.

[0012] Furthermore, the pressing arm includes two parallel connecting arms, a pressing plate is provided between the two connecting arms, the pressing plate is located above the two supporting blocks, and the pressing plate is provided with through holes having a number equal to that of the punching pins.

[0013] Furthermore, a receiving opening is provided on the two support blocks, and the width of the receiving opening is greater than the width of the aluminum strip.

[0014] Furthermore, sliding grooves are provided on both sides of the sliding seat, and the connecting arms are located in the sliding grooves.

[0015] Furthermore, the punch pin and the ejector pin have the same position and quantity, and the diameter of the punch pin is larger than the diameter of the ejector pin.

In this way, mechanical methods are used to replace manual operations, thereby improving the efficiency of riveting and ensuring the quality.

[0019] (2) The riveting protrusion on the riveting table can be used to expand the end of the rivet pressed into the aluminum strip by the ejector pin, thereby firmly fixing the ends of the two aluminum strips to prevent the rivet from falling off. At the same time, the height of the rivet is reduced, which is beneficial to the movement of the aluminum strip in the traction equipment.

[0020] (3) By providing a slide groove on the sliding seat, the movement stability of the entire pressing arm is improved.

[0021] (4) By using the through hole on the pressing plate, the pressing plate can press the aluminum strip tightly while avoiding the ejector pin and the punch pin.

[0022] (5) The receiving opening on the support block can be used to limit the left and right positions of the two aluminum strips placed therein, thereby ensuring the linearity after riveting. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] See attached Figure 1-2, shown is an aluminum strip riveting mechanism, including a driving unit 1 and a clamping unit 2. When in use, the driving unit 1 and the clamping unit 2 are both installed on a frame, wherein the clamping unit 2 is used to clamp and fix two aluminum strips 23 to be riveted, and the driving unit 1 is used to cooperate with the clamping unit 2 to punch and rivet the aluminum strip 23. Specifically, the driving unit 1 includes three pressing blocks 6 arranged side by side, each of which is connected to a first driving device 3. The pressing blocks 6 realize independent actions through the first driving devices 3 connected to each other, and the middle position of the three pressing blocks 6 The clamping blocks 6 at both ends are both installed with clamping blocks 7 by bolts on one side close to the clamping unit 2, wherein the first clamping block 6 holds a punching needle 9 through the clamping block 7, and the punching needle 9 is used to process the nail hole 25 of the aluminum strip 23 before riveting, and the third clamping block 6 holds an ejector pin 8 through the clamping block 7, and the ejector pin 8 is used to press the rivet 24 into the processed nail hole 25 to complete the riveting. It should be noted here that in order to ensure that the rivet 24 can be smoothly pressed into the nail hole 25, the diameter of the punching needle 9 is larger than the diameter of the ejector pin 8, and the positions of the punching needle 9 and the ejector pin 8 correspond one to one;

[0034] See attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 The clamping unit 2 shown includes a slide 10. When in use, the entire clamping unit 2 is fixed to the frame through the slide 10. A slide rail 11 is installed on the slide 10 along the length direction. A slider 12 is slidably provided on the slide rail 11. The slide 10 is provided with a sliding seat 13 through the top of the slider 12. The cross section of the sliding seat 13 is a square shape. The sliding seat 13 is sleeved on the periphery of the slide 10. Two support blocks 14 are symmetrically provided with bolts on one side of the sliding seat 13 close to the pressure block 6. A receiving port 17 is provided on the side of the two support blocks 14 close to each other. The receiving port 17 is used to place the two overlapping aluminum strips 23 when riveting the aluminum strips 23. The sliding seat 13 is provided with a riveting platform 15 between the two supporting blocks 14. The riveting platform 15 is provided with riveting protrusions 16 having the same number and spacing as the ejector pins 8 and the punch pins 9. The riveting protrusions 16 are umbrella-shaped. When in use, the rivet 24 is pressed into the nail hole 25 by the ejector pin 8. At this time, one end of the rivet 24 is buckled onto the riveting protrusion 16. Under the continuous pressure of the ejector pin 8, one end of the rivet 24 is pushed outward by the riveting protrusion 16 and fits around the nail hole 25 to achieve fixation.

[0035] At the same time, a second driving device 4 is provided at one end of the sliding seat 13 away from the supporting block 14, and a pressing arm 18 is provided at the output end of the second driving device 4. The pressing arm 18 includes two connecting arms 19 arranged in parallel on both sides of the sliding seat 13 and a pressing plate 20 located between the connecting arms 19. The pressing plate 20 is located above the supporting block 14, and a through hole 21 is opened on the pressing plate 20 at the same position as the ejector pin 8. When in use, two overlapping aluminum strips 23 are placed in the accommodating opening 17 of the supporting block 14, and then the second driving device 4 drives the pressing arm 18 to clamp and fix the aluminum strip 23, so as to prevent dislocation in the subsequent punching and riveting process, thereby ensuring the quality of riveting. At the same time, the through hole 21 can be used to complete the clamping and fixing of the aluminum strip 23 while avoiding the punching pin 9 and the ejector pin 8;

[0036] At the same time, in order to increase the stability of the pressing arm 18, a sliding groove 22 is vertically opened at the position of the sliding seat 13 corresponding to the connecting arm 19. The sliding groove 22 slides with the connecting arm 19. When the output end of the second driving device 4 is extended during use, the connecting arm 19 slides downward along the sliding groove 22, and the aluminum strip 23 is clamped and fixed by the pressing plate 20. When the connecting arm 19 slides upward, the pressing arm 18 releases the clamping of the aluminum strip 23.

[0037] At the same time, a third driving device 5 is installed at one end of the slide 10 through a mounting plate, and the output end of the third driving device 5 is connected to a nearby support block 14. When in use, the entire sliding seat 13 holding the aluminum strip 23 is moved along the slide rail 11 to the positions of the punch pin 9 and the ejector pin 8 for punching and riveting respectively.

[0038] In summary, when riveting the two aluminum strips 23, firstly, the ends of the two aluminum strips 23 are riveted. Figure 6 The overlap shown is placed in the accommodating opening 17 of the support block 14, and then the second driving device 4 is used to clamp the aluminum strip 23 through the pressure arm 18, and then the third driving device 5 is used to push the aluminum strip 23 to the position of the punch needle 9, and the first driving device 3 is used to drive the punch needle 9 to punch the aluminum strip 23, and then the third driving device 5 is used again to move the punched aluminum strip 23 to the position of the ejector pin 8, and then the ejector pin 8 is used to press the rivet 24 into the nail hole 25, and cooperate with the riveting protrusion 16 to complete the riveting of the two aluminum strips 23. It can be seen that the use of mechanical riveting instead of manual operation not only improves the efficiency of riveting, but also ensures the quality of riveting, and avoids various uncontrollable factors caused by manual labor.

[0039] See attached Figure 5-6When riveting the aluminum strip 23, firstly, the output end of the second driving device 4 is retracted to increase the distance between the pressing plate 20 of the pressing arm 18 and the supporting block 14 to facilitate the placement of the aluminum strip 23, then the two aluminum strips 23 to be riveted are overlapped end to end and placed in the accommodating port 17 of the supporting block 14, then the second driving cylinder is started to drive the pressing arm 18 to clamp and fix the aluminum strip 23 using the pressing plate 20, then the third driving device 5 is used to move the entire sliding seat 13 clamping the aluminum strip 23 to the bottom of the punch 9, then the first driving device 3 is used to drive the punch 9 to press down to complete the processing of the nail hole 25, then the aluminum strip 23 is moved to the position of the ejector pin 8 again, and the rivet 24 is inserted at the end of the ejector pin 8, then the first driving device 3 is used to drive the ejector pin 8 to press down and cooperate with the riveting protrusion 16 to complete the riveting.

[0040] It should be noted that in order to prevent the ejector pin 8 from pressing the entire ejector pin 8 into the inner hole of the rivet 24 when applying pressure to the rivet 24, the diameter of the ejector pin 8 is set to be larger than the inner diameter of the rivet 24. At the same time, in order to prevent the rivet 24 from falling off the ejector pin 8 when placing the rivet 24, the rivet 24 can also be directly placed in the nail hole 25 of the aluminum strip 23 and pressure is applied thereto by the ejector pin 8.

[0041] It should be noted that the first driving device 3 , the second driving device 4 and the third driving device 5 in the present invention can be one of an oil cylinder, an electric cylinder or a pneumatic cylinder.

[0042] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
