DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 one Figure 3 The utility model discloses a cold working machine tool for forging aluminum outer covering parts, including a base 1, which plays a role of fixing and supporting, and also includes a accommodating cavity 4 opened on the upper surface of the base 1, and mounting grooves 12 are opened on two opposite sides of the accommodating cavity 4. The upper end of the mounting groove 12 passes through the upper surface of the base 1, and the side of the mounting groove 12 is connected with the accommodating cavity 4. A fixing structure is provided at the bottom end of the mounting groove 12, and the fixing structure includes a fixing frame 8 fixedly arranged at the bottom end of the mounting groove 12, and a fixing cylinder 7 is fixedly arranged at the top end of the fixing frame 8. The fixing cylinder 7 and the fixing frame 8 are both hollow structures, and a through groove 71 penetrating the fixing cylinder 7 is opened on the outer circumferential surface of the fixing cylinder 7.

[0025] In addition, a reverse structure is also provided on the fixed structure, which includes a movable column 9 slidably arranged in the fixed cylinder 7. The movable column 9 can slide up and down in the fixed cylinder 7, and the bottom end of the movable column 9 passes through the fixed frame 8. When the movable column 9 moves downward to the maximum position, its bottom end contacts the bottom end of the mounting groove 12, and an inclined groove 91 passing through the movable column 9 is provided at the position where the movable column 9 is located in the through groove 71. The inclined groove 91 is connected with the through groove 71, and a pushing structure 6 is slidably provided in the inclined groove 91. The pushing structure 6 can move in the inclined groove 91. When the pushing structure 6 moves horizontally, the pushing structure 6 can drive the movable column 9 to move up or down by pushing the inclined groove 91.

[0026] In addition, a die 2 is provided in the accommodating cavity 4, and abutment blocks 21 are fixedly provided on both sides of the die 2 corresponding to the mounting groove 12. The abutment blocks 21 are used to drive the pushing structure 6 to move. When the abutment blocks 21 move downward, the pushing structure 6 can be pushed to move horizontally, thereby driving the movable column 9 to move upward. Conversely, the movable column 9 can be driven to move downward.

[0027] Furthermore, a first spring 10 is provided between the movable column 9 and the abutting block 21 . When the movable column 9 moves upward, the first spring 10 is compressed, so that the first spring 10 plays a buffering role on the die 2 .

[0028] In this embodiment, when stamping is performed, the die 2 will move downward for a distance, thereby causing the supporting block 21 to move downward, and then driving the pushing structure 6 to move. The pushing structure 6 moves horizontally under the limit of the through groove 71, and pushes the movable column 9 to move upward through the inclined groove 91 to push the first spring 10, so that the reverse structure cooperates with the first spring 10 to buffer the impact during stamping, and the vibration of the first spring 10 is offset by the constraint of the reverse structure, thereby avoiding the influence of the vibration generated by the first spring 10 during the compression or resetting process on the workpiece.

[0029] Combination Figure 3 and Figure 5 The pushing structure 6 includes an inclined rod 61, which is slidably arranged in an inclined groove 91. Contact heads 62 are fixed at both ends of the inclined rod 61. The two contact heads 62 are symmetrically arranged about the center of the inclined rod 61. Since the inclined rod 61 is inclined, the inclined rod 61 is moved when the height of the inclined rod 61 remains unchanged, and the movable column 9 can be driven to move through the inclined groove 91.

[0030] Combination Figure 3 and Figure 5 In order to enable the supporting block 21 to drive the pushing structure 6 when moving up and down, a first inclined surface is provided on the surface of the contact head 62 away from the inclined rod 61, and a supporting head 211 is provided on the side close to the pushing structure 6 at both ends of the supporting block 21, and a second inclined surface is provided on the side close to the inclined rod 61. The inclination angles of the first inclined surface and the second inclined surface are the same, so that the supporting head 211 can slide in contact with the contact head 62, thereby pushing the contact head 62.

[0031] Combination Figure 3 In order to enable the movable column 9 to move up or down when the die 2 moves down or up, the length direction of the inclined rod 61 is preferably perpendicular to the first inclined surface, thereby limiting the direction of the thrust of the inclined rod 61 on the movable column 9.

[0032] Combination Figure 4 In order to further buffer the die 2, a baffle 92 is fixedly provided at the bottom end of the movable column 9, and a second spring 11 is provided between the baffle 92 and the fixing frame 8, and the second spring 11 is sleeved on the outer circumferential surface of the movable column 9. When the movable column 9 moves upward, the second spring 11 will be compressed to buffer the die 2. By arranging the first spring 10 and the second spring 11 on the same straight line and at different positions, the first spring 10 and the second spring 11 can be compressed synchronously, thereby reducing the influence of the change of the elastic coefficient of a single spring on the device.

[0033] Combination Figure 1 In order to stamp the workpiece, a top seat 3 is provided above the die 2. The top seat 3 can move up and down in the vertical direction. A punch head 31 is fixedly provided on the surface of the top seat 3 close to the die 2. The punch head 31 can cooperate with the die 2 to stamp the workpiece so that the workpiece is formed into a desired shape.

[0034] Combination Figure 1 In order to push the movable column 9 to move, a top block 32 is fixedly provided on the surface of the top seat 3 close to the die 2. The top block 32 is arranged directly above the abutting block 21. When the top seat 3 moves downward, the top block 32 can contact the abutting block 21. When the top seat 3 contacts the base 1, the top block 32 pushes the abutting block 21 to move to the maximum position, so that the movable column 9 moves upward to the maximum position and compresses the first spring 10 and the second spring 11 to the maximum compression amount, thereby completing the buffering.

[0035] Combination Figure 2 In order to improve the stability of the buffering process, limit blocks 22 are fixedly provided on both sides of the die 2 where no abutting blocks 21 are provided. At the same time, a guide groove 5 is provided at the position of the accommodating cavity 4 corresponding to the limit blocks 22. The limit blocks 22 can move up or down in the guide groove 5, thereby limiting the movement of the die 2 in the horizontal direction to prevent the die 2 from shaking. When the die 2 moves downward to the maximum position, the guide groove 5 can also limit and support the die 2.

[0036] The working principle and use process of the utility model are as follows: when in use, the top seat 3 moves downward, and the punch head 31 cooperates with the die 2 to punch the workpiece into a desired shape. During the punching process, the top block 32 and the punch head 31 will push the abutment block 21 and the die 2 downward, so that the abutment head 211 pushes the contact head 62. Under the limitation of the through groove 71, the pushing structure 6 moves horizontally, and pushes the movable column 9 upward through the inclined rod 61, so that the first spring 10 and the second spring 11 are compressed to play a buffering role, and the movement of the die 2 is limited in the horizontal direction through the cooperation of the limit block 22 and the guide groove 5.

[0037] In summary, the cold working machine for forging aluminum outer covering parts is provided with a supporting block 21, a pushing structure 6, a movable column 9 and a first spring 10. The supporting block 21 is used to push the pushing structure 6, and then the pushing structure 6 is used to push the movable column 9, so that the vibration of the first spring 10 can be offset by the friction between the supporting head 211 and the contact head 62, thereby avoiding the influence of the vibration generated by the first spring 10 during the compression or resetting process on the workpiece; by arranging the first spring 10 and the second spring 11 on the same straight line and at different positions, the first spring 10 and the second spring 11 can be compressed synchronously, thereby reducing the influence of the change of the elastic coefficient of a single spring on the device; the movement of the die 2 is horizontally limited by the cooperation of the limit block 22 and the guide groove 5, thereby avoiding the shaking of the die 2. When the die 2 moves downward to the maximum position, the guide groove 5 can also limit and support the die 2.
