Technical Field

[0001] This utility model relates to the field of automotive aluminum parts manufacturing technology, and in particular to an aluminum sheet feeding and limiting structure for automotive aluminum parts manufacturing. Background Technology

[0002] Aluminum coils and sheets are made from pure aluminum or aluminum alloys, rolled into different thicknesses and widths by a cold rolling mill, and then slit by a slitting machine. They are lightweight and corrosion resistant. In the production of automotive aluminum parts, aluminum coils and sheets need to be fed into an automatic punching machine for processing. The automatic punching machine needs to be used in conjunction with an automatic feeder for feeding.

[0003] Existing automatic aluminum sheet feeding machines lack an aluminum sheet limiting structure at the inlet, affecting the feeding and transmission of aluminum sheets. Furthermore, the outlet of the automatic feeding machine lacks an aluminum sheet positioning structure, making it prone to damage from springing during stamping operations. This paper proposes an aluminum sheet feeding limiting structure for automotive aluminum parts production to solve the above problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5An aluminum sheet feeding and limiting structure for automotive aluminum parts production includes a base 1 and an aluminum sheet 2. An automatic feeding machine body 3 is mounted on the base 1. An arc-shaped guide frame 4 is fixed on the left feeding end of the automatic feeding machine body 3. A support seat 5 is fixedly connected to the right discharge end of the automatic feeding machine body 3. Several first guide rollers 6 are fixedly installed on the arc-shaped guide frame 4, and several second guide rollers 7 are fixedly installed on the support seat 5. The aluminum sheet 2 is placed on the several first guide rollers 6 and several second guide rollers 7 and discharged along the automatic feeding machine body 3. The several first guide rollers 6 are used to provide stable support for the aluminum sheet 2 entering the automatic feeding machine body 3, and the several second guide rollers 7 are used to provide stable support for the aluminum sheet 2 discharged from the automatic feeding machine body 3. Two limiting wheels 8 are fixedly installed on the upper end of the arc-shaped guide frame 4 near the left feeding end of the automatic feeding machine body 3. The two limiting wheels 8 slide and abut against the front and rear side walls of the aluminum sheet 2 respectively, and the two limiting wheels 8 are used to limit the side of the aluminum sheet 2.

[0018] An automatic feed machine body 3 has a feeding limit mechanism on its upper left side. The feeding limit mechanism includes two support plates 9 located on the upper left and right sides of the automatic feed machine body 3. The two support plates 9 are positioned near the front and rear ends of the automatic feed machine body 3, respectively. The two support plates 9 are connected and fixed to the automatic feed machine body 3 using two first bolts 10. Each support plate 9 has a cylindrical protrusion 11 at its upper end away from the automatic feed machine body 3. Each support plate 9 has a first L-shaped seat 12 above it. The upper ends of the two cylindrical protrusions 11 vertically penetrate the horizontal sections of the two first L-shaped seats 12. The lower ends of the horizontal sections of the two first L-shaped seats 12 are fixedly connected to first springs 13. 3. Two cylindrical protrusions 11 are respectively fitted onto each other and abut against the upper end of the support plate 9. The two first L-shaped seats 12 are horizontally rotatably mounted on the opposite side walls near the lower end. The first limiting rollers 14 roll against the upper end of the aluminum sheet 2. The cylindrical protrusions 11 and the support plate 9 are integrally cast. The upper end of the aluminum sheet 2 located at the feed port of the automatic feed machine body 3 rolls against the first limiting rollers 14 between the two first L-shaped seats 12. When the aluminum sheet 2 is fed into the automatic feed machine body 3, the first limiting rollers 14 between the two first L-shaped seats 12, together with the first spring 13, provide a limit for the feeding aluminum sheet 2 under the limiting action of the cylindrical protrusions 11, ensuring the smooth feeding of the aluminum sheet 2.

[0019] The automatic feed machine body 3 has a discharge limiting mechanism on its right side. The discharge limiting mechanism includes fixed seats 15 fixedly connected to the front and rear side walls of the automatic feed machine body 3. Both fixed seats 15 are located near the right side of the automatic feed machine body 3. Each fixed seat 15 has a rectangular slot 16 on its right side wall. Limiting rods 17 are provided on the top and bottom surfaces of both rectangular slots 16. The fixed seats 15 and the limiting rods 17 are connected and fixed using two second bolts 18. Each limiting rod 17 is fitted with a second spring 19, and each limiting rod 17 is slidably fitted with a slider 20. The side wall of the slider 20 slides and abuts against the inner wall of the rectangular slot 16. When the slider 20 moves along the limiting rod 17, it can smoothly compress the second spring 19. When the aluminum sheet 2 at the discharge end of the automatic feed machine body 3 rolls and abuts against the second limiting roller 24, the aluminum sheet 2 is subjected to stamping force, which is transmitted to the second limiting roller 24. The second limiting roller 24 is subjected to force and... The two second L-shaped seats 22 and the connecting block 21 drive the slider 20 to move vertically along the limiting rod 17, and make the slider 20 smoothly compress the second spring 19 on the limiting rod 17. This allows the second limiting roller 24 to cooperate with the slider 20 and the second spring 19 on the limiting rod 17 to press and limit the advancing aluminum sheet 2, preventing the advancing aluminum sheet 2 from being damaged by bouncing during the stamping operation. The two sliders 20 are fixedly connected to the connecting block 21 at one end outside the rectangular slot 16. The two connecting blocks 21 are fixedly connected to the second L-shaped seats 22 at the ends away from the sliders 20. The connecting block 21 and the second L-shaped seats 22 are connected and fixed by two third bolts 23. The two second L-shaped seats 22 are horizontally rotatably connected to the opposite sidewalls away from the connecting block 21. The second limiting roller 24 rolls and abuts against the upper end of the aluminum sheet 2. The slider 20 and the connecting block 21 are welded and fixed. The cross-section of the slider 20 and the connecting block 21 is T-shaped.

[0020] In use, the aluminum sheet 2 is mounted on several first guide rollers 6 on an arc-shaped guide frame 4. The aluminum sheet 2 is then fed into the automatic feed machine body 3 after passing through two limiting rollers 8. The automatic feed machine body 3 drives the aluminum sheet 2 for feeding and transmission. The two limiting rollers 8 provide limiting for the sides of the aluminum sheet 2. Simultaneously, the upper end of the aluminum sheet 2 located at the feed inlet of the automatic feed machine body 3 rolls against the first limiting rollers 14 between the two first L-shaped seats 12. As the aluminum sheet 2 is fed and transmitted with the automatic feed machine body 3, the two… The first limiting roller 14 between the first L-shaped seats 12, in conjunction with the first spring 13, provides a limit for the advancing aluminum sheet 2 under the limiting action of the cylindrical protrusion 11, ensuring the smooth advancement of the aluminum sheet 2. The aluminum sheet 2 is discharged along the right discharge end by the automatic advancing machine body 3 and transmitted along several second guide rollers 7. The second limiting roller 24 between the two second L-shaped seats 22, in conjunction with the slider 20 on the limiting rod 17 and the second spring 19, presses and limits the advancing aluminum sheet 2 to prevent it from bouncing up and being damaged during the stamping operation.
