Abstract
Description
Technical Field
[0001] The utility model relates to a clamping device for forgings. Background Art
[0002] Forging is a machining process where metal is subjected to pressure and plastic deformation to form the required shape or appropriate compression force. This force is typically achieved by using a hammer or pressure. The forging process builds a fine grain structure and improves the physical properties of the metal. In the actual use of parts, a correct design enables the grain flow in the direction of the main pressure. Forgings need to be consistent from piece to piece without any porosity, inclusions or other defects. The components produced by this method have a high strength-to-weight ratio. Existing equipment is inconvenient for clamping metal tube forgings, and it is easy to scratch the surface and inner wall of the forging, which directly affects the yield rate of the forgings.

[0016] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, Figures 1 to 3 The figure schematically shows the structure of an implementation mode of the present utility model. The present utility model will be further described below in conjunction with a specific implementation mode.
[0017] Example
[0018] like Figure 1-Figure 3 As shown, the utility model provides a clamping device for forgings, whose structure includes a clamping unit 1, a bottom bearing seat 2, an assembly cylinder 3, a movable arm 4, and a control arm device 5. The clamping unit 1 is arranged below the control arm device 5 and is locked with the control arm device 5. A movable arm 4 is arranged below the control arm device 5. The movable arm 4 is arranged above the assembly cylinder 3 and is movably connected with the assembly cylinder 3. A bottom bearing seat 2 is arranged below the assembly cylinder 3, and the assembly cylinder 3 is locked with the bottom bearing seat 2. The clamping unit 1 includes an assembly splint 11, a movable inner groove 12, a spring inner tube 13, a support plate 14, a buffer gasket 15, and a contact tube device 16. The contact tube device 16 is buckled on the inner side of the movable inner groove 12 and has a clearance fit with the movable inner groove 12. The spring inner tube 13 is embedded in the middle of the movable inner groove 12. The spring inner tube 13 is arranged above the inner end of the contact tube device 16 and forms an extrusion relationship. The movable inner groove 12 is arranged in the middle of the support plate 14. The outer side of the support plate 14 is provided with an assembly splint 11 and is locked with the assembly splint 11. The outer ring of the inner side of the support plate 14 is glued with a buffer gasket 15. The contact tube device 16 includes a contact strip 161, an anti-sliding block 162, a butt joint tube 163, a stress tube 164, and a telescopic shaft 165. The anti-sliding block 162 is arranged above the contact strip 161 and is buckled with the contact strip 161. The contact strip 161 is embedded in the upper end of the stress tube 164. The outer side of the stress tube 164 is buckled with the butt joint tube 163. The inner side of the butt joint tube 163 is buckled with the telescopic shaft 165. The contact tube device 16 is made of rubber material and has anti-slip texture on the surface.
[0019] The working principle of the above technical solution is explained as follows: through the cooperation between the bottom bearing seat 2 and the assembly cylinder 3, it is connected to the corresponding automatic control unit, and with the rotation of the movable arm 4, it can rotate in multiple directions. By issuing the target clamping command, the control arm device 5 is responsible for execution, and then under the coordination of the assembly clamping plate 11 and the support plate 14, the telescopic shaft 165 is driven to telescope accordingly according to the different lengths of the forged pipes. At this time, the butt-jointed pipes 163 in the two directions will eventually form an interlocking relationship. At this time, the upward displacement is lifted, and the contact strip 161 and the anti-sliding block 162 at the upper end of the stress tube 164 will contact the inner wall of the forged pipe without causing scratches, which effectively plays a protective role, and the buffer gasket 15 plays a role in protecting the edges on both sides. During transportation, the stress tube 164 will squeeze the spring inner tube 13 and move up along the movable inner groove 12, and then when the transportation and clamping process is completed, it can be separated outwards, and the spring inner tube 13 plays an auxiliary role in resetting.
