Abstract

The utility model discloses a machining table for an annular forge piece. The machining table comprises a machining table body and a maintaining assembly. A movable hole is formed in the middle of the machining table, and a bearing plate is arranged in the movable hole. And a retaining seat and retaining pieces which are rotationally and symmetrically arranged are arranged in the retaining assembly, one ends of the symmetrically arranged retaining pieces are hinged to the two ends of the retaining seat through hinge rods correspondingly, and retaining blocks are arranged at the other ends of the retaining pieces. According to the machining table for the annular forge piece, a middle round hole of the annular forge piece can be subjected to limiting treatment through limiting of the maintaining assembly. When the annular forge piece is installed, only a direct pressing mode needs to be adopted, and when the annular forge piece needs to be taken out, the annular forge piece can be taken out only by moving the two unlocking rods towards the middle. And meanwhile, limiting can be achieved through the first spring and the retaining assembly, and positioning operation can be effectively achieved under the condition that the surface of the annular forge piece is not damaged.

Description

Technical Field

[0001] This utility model relates to forging processing technology, and more particularly to a processing table for ring forgings. Background Technology

[0002] Forgings are workpieces or blanks obtained by forging metal billets. By applying pressure to a metal billet, plastic deformation is caused, which alters its mechanical properties. Forgings can be classified into cold forging, warm forging, and hot forging based on the temperature at which the billet is processed. Cold forging is generally performed at room temperature, while hot forging is performed at a temperature above the recrystallization temperature of the metal billet. After forging, forgings require surface grinding and drilling on a machining table.

[0003] After forming, the outer surface of the annular forging needs to be ground, which requires a limiting block to facilitate the grinding process. Currently, the limiting block is used to restrict the annular forging using a cylinder or screw, but it is difficult to control the pressure, which can easily lead to surface damage to the annular forging.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figures 1 to 5 As shown, the processing table for this type of annular forging of the present invention includes a processing table 1 and a holding assembly 2. The annular forging 3 is disposed on a support plate 4 on the processing table 1, and the annular forging 3 is limited by the holding assembly 2 disposed at the upper end of the support plate 4.

[0022] The annular forging 3 has a circular hole 5 and a stepped surface 6 in the middle. The retaining component 2 is set in the circular hole 5, while the retaining block 7 restricts the stepped surface 6, thereby setting the annular forging 3 on the bearing plate 4.

[0023] A movable hole 8 is formed in the middle of the processing table 1, and a support plate 4 is provided in the movable hole 8. A first spring 9 is provided in the movable hole 8, and the first spring 9 is located at the lower end of the support plate 4. The first spring 9 is used to support the support plate 4, so that the support plate 4 can automatically reset after being subjected to downward pressure, thereby pushing the annular forging 3 on the support plate 4 towards the holding assembly 2, which is conducive to the grinding of the outer wall surface of the annular forging 3.

[0024] A positioning sleeve 10 is also provided inside the movable hole 8, with a positioning hole 11 formed in the middle of the positioning sleeve 10. A first bolt 12 is provided in the middle of the retaining seat 13, and the first bolt 12 passes through the retaining seat 13 and is set in the positioning hole 11. A positioning sleeve 10 is provided in the middle of the bearing plate 4, passing through a small hole 14.

[0025] The retaining assembly 2 is mounted on the support plate 4. The retaining assembly 2 includes a retaining seat 13 and rotationally symmetrical retaining members 15. One end of each symmetrically arranged retaining member 15 is hinged to both ends of the retaining seat 13 via a hinge rod 16, and the other end of each retaining member 15 has a retaining block 7. An unlocking rod 17 is provided on the retaining member 15. When both unlocking rods 17 move simultaneously towards the first bolt 12 in the middle, the retaining block 7 also moves, causing the retaining member 15 to rotate hinged around the hinge rod 16. This prevents the retaining block 7 from acting on the stepped surface 6, allowing the annular forging 3 to be removed.

[0026] A second bolt 18 and a second limiting hole 19 are provided in the middle of the retaining member 15. A first limiting hole 20 that mates with the second limiting hole 19 is provided on the retaining seat 13. A second spring 21 is provided in the first limiting hole 20 and the second limiting hole 19. The second spring 21 is sleeved on the second bolt 18. A threaded hole 22 is provided in the first limiting hole 20. A threaded portion 23 that mates with the threaded hole 22 is provided on the second bolt 18. Pressing the unlocking rod 17 can compress the second spring 21, thereby causing the retaining block 7 to no longer be at the upper end of the stepped surface 6.

[0027] A retaining hole 24 is provided in the middle of the retaining block 7, and a third bolt 25 is provided in the retaining hole 24. The third bolt 25 is used to limit the position of the retaining block 7. At the same time, a guide ramp 26 is provided on the retaining block 7. When the annular forging 3 is installed, the guide ramp 26 can be directly pressed to guide the annular forging 3. The annular forging 3 can push the retaining block 7, so that the retaining block 7 is subjected to force to drive the retaining member 15 to rotate and compress the second spring 21. Then the annular forging 3 acts on the bearing plate 4, and the bearing plate 4 is subjected to force, so that the first spring 9 is compressed. The first spring 9 generates elastic force, pushing the annular forging 3 in the opposite direction to the retaining block 7, thereby limiting the position of the annular forging 3 and facilitating the grinding of the outer wall surface of the annular forging 3.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
