specific Embodiment approach 1

[0021] As can be seen from the accompanying drawings, the horse frame for forging and reaming of the present program includes a horse bar 1 and a support plate 2 for supporting the horse bar 1, the horse bar 1 is used to support the blank 10, and a bracket for The arc groove 9 is used to place the horse bar 1 when reaming, and a horse bar push-pull mechanism for pushing the horse bar 1 is arranged on one side of the support plate 2 .

specific Embodiment approach 2

[0023] On the basis of Embodiment 1, there are two support plates 2 , and the same arc-shaped groove 9 is provided above each support plate 2 . Two support plates 2 are fixed on a bottom plate 3 , and a rib 4 is also arranged between the support plates 2 and the bottom plate 3 . The length of the horse bar 1 is a, the thickness of the support plate 2 is b, the distance between the two support plates 2 is c, and a>2b+c.

[0024] The push-pull mechanism of the horse bar includes an oil cylinder 5 and an oil cylinder support frame 6 for fixing the oil cylinder 5. The oil cylinder 5 is fixed on the oil cylinder support frame 6 through a fixing seat 8, and the oil cylinder support frame 6 is fixed on the support plate 2. The oil cylinder 5 is used for When driving the horse bar 1 to make the horse bar 1 move back and forth in the curved surface formed by the two arc-shaped grooves 9, the oil cylinder 5 drives the horse bar 1 to advance or retreat a distance of d, where d>2b+c. A s...

specific Embodiment approach 3

[0026] A method for reaming a hole based on the forged reaming horse frame of Embodiment 1 or 2. The reaming steps are as follows: firstly, an oil cylinder is installed on the support plate, and the oil cylinder pushes and pulls the horse bar, and ensures that the horse bar is positioned between the two support plates. Movement in the curved surface where the arc-shaped groove is located; observe the state of the horse bar, make the horse bar in the retracted state, that is, make the horse bar in the retracted state through the oil cylinder, and the front end of the horse bar does not exceed the support plate of the fixed oil cylinder; use the manipulator to hold the blank and place it Insert it into the middle of the two support plates, and align the inner diameter of the blank with the horse bar; use the oil cylinder to push the horse bar through the inner diameter of the blank, and make the horse bar in the arc-shaped groove, and the two support plates support the horse bar; ...

Abstract

The invention provides a mandrel supporter for forging reaming and a reaming method. The mandrel supporter comprises a mandrel and supporting plates for supporting the mandrel. Arc-shaped grooves areformed in the upper parts of the supporting plates, and the arc-shaped grooves are used for placing of the mandrel during reaming, and mandrel push-pull mechanisms for pushing the mandrel are arrangedon one sides of the supporting plates. During reaming, the mandrel is pushed to penetrate through the inner diameter of a blank by an oil cylinder, after reaming is carried out to the process dimension, a manipulator clamps the blank, the mandrel is wound by the oil cylinder, the front end of the mandrel does not exceed the supporting plates for fixing the oil cylinder, and the blank is removed.Since the mandrel can be automatically adjusted by the oil cylinder, the production efficiency is greatly improved and the production cost is reduced, and because the mandrel does not require manual operation when penetrating or withdrawing the blank, the safety of the reaming process operation is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the field of hole reaming for forging ring and cylinder forgings, in particular to a horse frame for forging and reaming holes and a method for reaming holes. Background technique [0002] The forging of ring and cylindrical forgings needs to go through the hole reaming process. The tooling used in this process is a horse frame and a horse bar. The existing horse frame and horse bar are independent. When the forging is reamed, the blank is placed on the In the middle of the horse frame, the hoisting bar is penetrated into the inner diameter of the billet, and the billet is placed on the horse rack through the bar to ream the hole. After the hole is reamed to the process size, the bar is hoisted to the designated position by the car. figure 1 shown. [0003] There are the following problems in the existing horse frame tooling: 1, the forging efficiency is low, and in actual operation, the horse bar is lifted into the blank inne...
