Description

Combined reaming core rod

Technical Field

The utility model relates to a combination reaming plug.

Background

In the forging process, saddle reaming is often required to be carried out, so that the outer diameter and the inner hole of the ring forging are increased, the wall thickness is reduced, in the saddle reaming process, a core rod is required to be used, the diameter of the core rod is required to be smaller than the size of the inner hole of the forging and can be placed in the ring forging, but along with the increase of the size of the ring forging, the diameter of the core rod is smaller and smaller relative to the inner diameter of the ring forging, so that the contact surface between the inner hole of the ring forging and the core rod is smaller and smaller, in the processing of the ring forging, saddle reaming is required to be carried out by using a small-diameter core rod, and after the outer diameter inner hole of the ring forging is increased to a certain size, a large-diameter core rod is replaced to continue saddle reaming to a preset size; therefore, two sets of tools are needed in the trestle reaming process, the production cost is increased, the working efficiency is reduced, the heating frequency is increased for special alloys, and the inner hole is easy to crack; in the process of reaming the saddle, the single rolling reduction is small, the center of the forge piece cannot be completely forged, and the final structure performance of the ring forge piece is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a combination reaming plug, avoided the increasingly little condition of contact surface of ring rolling spare hole and plug, need not to change the frock, according to work piece size, horse size customized, the suitability is high, improves work efficiency, improves the final organizational performance of ring rolling spare.

In order to achieve the purpose, the technical scheme of the utility model a design a combination reaming plug, the horse-frame supporting seat is equipped with the plug on the horse-frame supporting seat, and the loop forming element is established to the cover on the plug, and the lower limb of back loop forming element and the base of horse-frame supporting seat are equipped with the interval on the plug is established to the loop forming element cover. The ring-shaped piece is designed according to the size of the saddle support seat, so that the contact surface between the inner hole of the ring forging and the core rod is the largest as far as possible, namely the contact surface between the inner hole of the ring forging and the ring-shaped piece is indicated, and the diameter of the core rod is increased and expanded due to the arrangement of the ring-shaped piece.

The further technical scheme is that the core rod is in a stepped column shape with thick middle and thin two ends, the trestle support seats are provided with a pair of trestle support seats, and the parts of the trestle support seats facing the small-size section of the core rod are provided with V-shaped grooves for placing the core rod.

The further technical proposal is that the distance between the two trestle supporting seats is larger than the width of the ring-shaped piece.

The further technical scheme is that the core rod is in a three-step ladder shape with thick middle and thin two ends, a first ring pad is sleeved on the middle section of the core rod, and the annular piece is a second ring pad sleeved outside the first ring pad.

The further technical scheme is that the distance between the horse frame supporting seats is matched with the width of the first ring pad, and the width of the second ring pad is smaller than that of the first ring pad.

The utility model has the advantages and the beneficial effects that: the condition that the contact surface of the inner hole of the ring forging and the core rod is smaller and smaller is avoided, the tool does not need to be replaced, the ring forging and the mandrel are customized according to the size of the workpiece and the size of the horse, the adaptability is high, the working efficiency is improved, and the final organization performance of the ring forging is improved. The ring-shaped piece is designed according to the size of the saddle support seat, so that the contact surface between the inner hole of the ring forging and the core rod is the largest as far as possible, namely the contact surface between the inner hole of the ring forging and the ring-shaped piece is indicated, and the diameter of the core rod is increased and expanded due to the arrangement of the ring-shaped piece.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-2, the utility model relates to a combination reaming plug, horse rest support seat 1 is equipped with plug 2 on the horse rest support seat 1, and the loop forming element 3 is established to the cover on plug 2, and the lower limb of loop forming element 3 is equipped with the interval with the base of horse rest support seat 1 after the loop forming element 3 cover is established on plug 2. The core rod 2 is in a ladder column shape with thick middle and thin two ends, the trestle support seat 1 is provided with a pair of trestle support seats, and the part of the trestle support seat 1 facing the small-size section of the core rod 2 is provided with a V-shaped groove 4 for placing the core rod 2. The distance between the two trestle supporting seats 1 is larger than the width of the ring-shaped piece 3. The core rod 2 is a three-step ladder column shape with thick middle part and thin two ends, the first ring pad 5 is sleeved on the middle part of the core rod 2, and the ring piece 3 is a second ring pad sleeved outside the first ring pad 5. The spacing of the horse-rest supporting seat 1 is matched with the width of the first ring pad 5, and the width of the second ring pad is smaller than that of the first ring pad 5.
