Description

Technical Field

[0001] The utility model relates to the technical field of forging processing, in particular to an auxiliary positioning device for forging processing. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet to cause it to undergo plastic deformation, its mechanical properties can be changed. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally performed at room temperature, while hot forging is performed at a temperature higher than the recrystallization temperature of the metal billet. Forging can eliminate the porosity and holes in the metal and improve the mechanical properties of the forging.

[0003] During the forging process, the metal blank needs to be placed on a press to extrude and deform its end face to change its plastic properties. In the process of applying external force to the metal blank, an auxiliary positioning device needs to be used to fix its central position. The traditional cylindrical metal blank auxiliary positioning device cannot perform convenient and quick clamping operations, and the clamping effect is not strong enough, which affects the working efficiency of the device; and it is inconvenient to adjust the placement angle of the forging during use, resulting in a high failure rate of forging processing, which will cause considerable economic losses to people and bring many inconveniences to workers.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3 As shown, an auxiliary positioning device for forging processing includes a base 1, a slidable movable seat 2 is provided on the top surface of the base 1 along its length direction, a rotating shaft 3 is supported by a bearing and penetrated through the middle position of the outer side surface of the movable seat 2, and a connecting seat 4 with an arc structure is fixedly provided on the end surface of the rotating shaft 3, so that it can match the outer wall of the cylindrical metal blank, and arc grooves 5 are symmetrically provided on the outer sides of the left and right ends of the connecting seat 4, and grooves 6 are symmetrically provided at the ends of the two arc grooves 5 away from the rotating shaft 3, respectively, and clamping plates 7 with an arc structure are respectively hinged in the two grooves 6, and electric push rods 8 are respectively hinged at the rear ends of the two clamping plates 7 and the corresponding rear ends of the connecting seat 4. The electric push rods 8 at both ends are set synchronously. By controlling the extension and retraction of the electric push rods 8, the clamping plates 7 at both ends are driven to swing relative to or away from each other, so as to conveniently and quickly clamp and position the middle position of the cylindrical metal billet. Under the action of the arc groove 5, the interference between the end of the electric push rod 8 and the end of the connecting seat 4 can be avoided. The end of the rotating shaft 3 extending out of the front side of the moving seat 2 is connected to the output shaft of the motor 2 9. The motor 2 9 is started to drive the rotating shaft 3 to rotate, and then drive the connecting seat 4 to rotate, so that the angle of the positioned metal billet can be adaptively adjusted according to needs. An adjustment device for sliding control of the moving seat 2 is also provided on the top surface of the base 1.

[0019] The adjusting device includes a tooth plate 11, a gear 13 and a motor 14. A mounting groove 10 is provided on the top surface of the base 1 corresponding to the middle position of the moving seat 2 along its length direction, and a tooth plate 11 is fixedly provided on the bottom wall of the mounting groove 10. A connecting groove is also provided in the middle position of the bottom surface of the moving seat 2, and a U-shaped frame 12 is fixedly provided on the top wall of the connecting groove corresponding to the tooth plate 11. A gear 13 meshing with the tooth plate 11 is provided in the U-shaped frame 12 through a half-axis rotation, and the end of the half-axis extending out of the U-shaped frame 12 is connected to the output shaft of the motor 14. When the motor 14 is started, the gear 13 is driven to rotate, and under the action of meshing with the tooth plate 11, the moving seat 2 can be driven to slide back and forth, so that the position of the metal blank after its positioning can be adaptively adjusted according to needs.

[0020] Slide rails 15 are fixedly provided on the top surface of the base 1 at the left and right ends of the installation groove 10 along its length direction, and sliding seats 16 matching them are provided on the two slide rails 15 respectively. The top ends of the two sliding seats 16 are fixedly connected to the corresponding positions on the bottom surface of the moving seat 2 respectively, and limit seats 17 are fixedly provided on the front and rear end surfaces of the two slide rails 15 respectively. The cooperation between the slide rails 15 and the sliding seats 16 can ensure the stability of the moving seat 2 during the forward and backward movement.

[0021] In specific use, first control the contraction of the electric push rod 8 to make the clamping plates 7 at both ends move away from each other, and then start the motor 14 to drive the gear 13 to rotate. Under the action of meshing with the toothed plate 11, it can drive the movable seat 2 to slide back and forth, so that the clamping plate 7 moves to the cylindrical metal blank. Then control the extension of the electric push rod 8 to drive the clamping plates 7 at both ends to move relatively, so that the middle position of the metal blank can be clamped and positioned conveniently and quickly. During use, the rotating shaft 3 is driven to rotate by starting the motor 2 9, and then the connecting seat 4 is driven to rotate. In this way, the angle of the positioned metal blank can be adaptively adjusted according to needs, thereby improving the practicality of the device.
