Description

Technical Field

[0001] This utility model belongs to the technical field of cold heading machine, specifically relating to a material turning device for a cold heading machine. Background Technology

[0002] A cold heading machine is a stamping machine used in mechanical manufacturing. It shapes raw materials into the required shape without altering them (mainly by softening or hardening them).

[0003] In the processing of cold heading machines, materials often need to be flipped to achieve processing on different surfaces. Existing material flipping devices for cold heading machines mainly consist of two worktables, a flipping mechanism, and a material fixing mechanism. When flipping materials, the material fixing mechanism first secures the material, and then the flipping mechanism flips the material from one worktable to another. However, because the two worktables on the material flipping device occupy a large space, it poses certain difficulties for the layout of the production workshop and the installation of the equipment. At the same time, since the position of the material fixing mechanism is fixed, it cannot be adjusted according to different shapes of materials, resulting in low adaptability of the material flipping device.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1 to 8 As shown, a material turning device for a cold heading machine includes a base plate 1. A workbench 2 is fixedly connected to the upper surface of the base plate 1. An electric telescopic rod 3 is fixedly connected to the upper surface of the workbench 2. A rotating mechanism 4 is fixedly connected to the upper surface of the electric telescopic rod 3. A second motor bracket 5 is fixedly connected to the right side of the rotating mechanism 4. A second stepper motor 6 is fixedly connected to the inner wall of the second motor bracket 5. A third rotating shaft 7 is fixedly connected to the output end of the second stepper motor 6. A second bearing 8 is fixedly connected to both the surface of the third rotating shaft 7 and the inner wall of the rotating mechanism 4. A second square column 9 is fixedly connected to the left side of the third rotating shaft 7. A strip hole 10 is opened inside the second square column 9. A fixing mechanism 11 is fitted to both the inner wall of the strip hole 10 and the surface of the second square column 9. A groove 12 is opened on the upper surface of the workbench 2. The inner wall of the groove 12 is fitted to the surface of the fixing mechanism 11.

[0028] The rotating mechanism 4 includes a first connecting block 41, a second connecting block 42, a first bearing 43, a first cylinder 44, a second cylinder 45, a first square column 46, a circular hole 47, a first stepper motor 48, and a first motor bracket 49. The bottom of the first connecting block 41 and the bottom of the second connecting block 42 are fixedly connected to the upper surface of the electric telescopic rod 3. The inner wall of the first connecting block 41 and the inner wall of the second connecting block 42 are fixedly connected to the outer ring of the first bearing 43. The surface of the first cylinder 44 and the surface of the second cylinder 45 are fixedly connected to the inner ring of the first bearing 43. The first square post 46 is fixedly connected to the front and back sides of the first cylindrical post 44 and the second cylindrical post 45, respectively. A circular hole 47 is opened inside the first square post 46, and the inner wall of the circular hole 47 is fixedly connected to the inner wall of the second bearing 8. The output end of the first stepper motor 48 is fixedly connected to the back side of the first cylindrical post 44. The back side of the first stepper motor 48 is fixedly connected to the inner wall of the first motor bracket 49. The front side of the first motor bracket 49 is fixedly connected to the back side of the first connecting block 41. The right side of the first square post 46 is fixedly connected to the left side of the second motor bracket 5.

[0029] It should be noted that the electric telescopic rod 3 can control the rotating mechanism 4 to move up or down, so that when the material fixed on the fixing mechanism 11 is flipped, the electric telescopic rod 3 can make the flipped material parallel to the worktable 2.

[0030] The first stepper motor 48 controls the left and right rotation of the first square column 46, and the second stepper motor 6 controls the forward and backward rotation of the second square column 9.

[0031] like Figures 1 to 2 As shown, the fixing mechanism 11 includes a third column 111, a U-shaped plate 112, a threaded column 113, a nut 114, an electromagnet 115, and a first anti-slip pad 116. The surface of the third column 111 is in contact with the inner wall of the groove 12. The upper surface of the third column 111 is fixedly connected to the bottom of the electromagnet 115. The right side of the third column 111 is fixedly connected to the left side of the U-shaped plate 112. The inner wall of the U-shaped plate 112 is fixedly connected to the left side of the threaded column 113. The surface of the threaded column 113 is in contact with the inner wall of the strip hole 10. The inner wall of the U-shaped plate 112 is in contact with the surface of the second column 9. The surface of the threaded column 113 is threadedly connected to the inner wall of the nut 114. The left side of the nut 114 is in contact with the right side of the second column 9. The upper surface of the electromagnet 115 is bonded to the bottom of the first anti-slip pad 116.

[0032] The upper surface of the workbench 2 is bonded with a second anti-slip pad 13, and the upper surface of the first anti-slip pad 116 is flush with the upper surface of the second anti-slip pad 13.

[0033] It should be noted that when the material is above the electromagnet 115, the attraction of the electromagnet 115 to the material allows the material to come into close contact with the second anti-slip pad 13. The friction between the material and the second anti-slip pad 13 can fix the material on the worktable 2. When the material is separated from the worktable 2 due to the rotation of the fixing mechanism 11, the attraction of the electromagnet 115 to the material allows the first anti-slip pad 116 to come into close contact with the material. The friction between the first anti-slip pad 116 and the material can fix the material on the fixing mechanism 11.

[0034] When the user rotates nut 114 to loosen the second square post 9 from the U-shaped plate 112, the threaded post 113 can move back and forth within the slotted hole 10. When the user rotates nut 114 to clamp the second square post 9 from the U-shaped plate 112, the threaded post 113, and nut 114 together prevent the fixing mechanism 11 from changing its position on the second square post 9. Furthermore, through the cooperation of the second square post 9, slotted hole 10, U-shaped plate 112, threaded post 113, and nut 114, the position of the fixing mechanism 11 on the second square post 9 can be adjusted according to the shape of the material, thus enabling the material turning device to adapt to materials of any shape.

[0035] like Figures 1 to 2 As shown, hollow columns 14 are fixedly connected to both sides of the first connecting block 41 and both sides of the second connecting block 42. A column 15 is attached to the inner wall of the hollow column 14. The bottom of the column 15 is fixedly connected to the upper surface of the base plate 1. Through the cooperation of the hollow column 14 and the column 15, the first connecting block 41 and the second connecting block 42 can only move up and down.

[0036] like Figures 1 to 7 As shown, a hollow block 16 is fixedly connected to the surface of the third rotating shaft 7. A reinforcing ring 17 is fixedly connected to the surface of the hollow block 16 and the surface of the second square column 9. Through the cooperation of the hollow block 16 and the reinforcing ring 17, the second square column 9 and the third rotating shaft 7 can be more firmly fixed.

[0037] The working principle of this utility model is as follows: First, adjust the position of the fixing mechanism 11 on the second square column 9 according to the shape of the material. During adjustment, first, the fixing mechanism 11 is rotated 45° to the right by the first stepper motor 48. Then, by rotating the nut 114, the nut 114 and the U-shaped plate 112 are loosened from the second square column 9. Then, by pushing and pulling the third square column 111, the fixing mechanism 11 is moved to a suitable position. Then, by rotating the nut 114, the nut 114 and the U-shaped column clamp the second square column 9. At this time, through the cooperation of the U-shaped plate 112, the threaded column 113 and the nut 114, the position of the fixing mechanism 11 on the second square column 9 cannot be changed. Then, the fixing mechanism 11 is rotated back into the groove 12 by the first stepper motor 48.

[0038] Then, place the material on the workbench 2 and position it above the second anti-slip pad 13. Then, turn on the electromagnet 115 to make it attract the material. At this time, the attraction makes the material and the second anti-slip pad 13 come into close contact, and the friction between the second anti-slip pad 13 and the material fixes the material on the workbench 2.

[0039] Then, the first stepper motor 48 causes the fixing mechanism 11 to rotate 90° to the right, and the electromagnet 115 attracts the material, so that the first anti-slip pad 116 is in close contact with the material during the rotation of the fixing mechanism 11, and the friction between the first anti-slip pad 116 and the material prevents the material on the fixing mechanism 11 from falling off.

[0040] When the fixing mechanism 11 rotates 90° to the right, the material is flipped by the second stepper motor 6, and the flipped material is rotated 90° to the left by the first stepper motor 48. At the same time, the rotating mechanism 4 is moved up a certain distance by the electric telescopic rod 3. At this time, the flipped material is parallel to the worktable 2 and contacts the second anti-slip pad 13. Then, by turning off the electromagnet 115, the flipped material can be separated from the fixing mechanism 11.

[0041] After the flipped material is removed from the workbench 2, the first stepper motor 48 causes the fixing mechanism 11 to rotate 90° to the right, and the second stepper motor 6 causes the fixing mechanism 11 to flip. Then, the first stepper motor 48 causes the flipped fixing mechanism 11 to rotate 90° to the left, and the electric telescopic rod 3 causes the rotating mechanism 4 to move down a certain distance. At this time, the fixing mechanism 11 can be moved into the groove 12, and the electromagnet 115 is positioned above the third column 111.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
