Abstract

The utility model relates to a reaming frock for step is taken over, anvil on horse frame, reaming plug and step, the reaming plug is arranged in on the horse frame, the anvil is located the horse frame top on the step, the anvil includes the upper padding plate on the step, the upper padding plate below cooperation step is taken over the little excircle and is connected the flat anvil, the connecting hole that is used for connecting the press is still offered to the upper padding plate, a reaming frock for step is taken over, can make the step take over hole reaming for straight hole, product quality is good, and reaming is efficient.

Description

A reaming frock for step is taken over

Technical Field

The utility model relates to a forging device especially relates to a reaming frock for step is taken over.

Background

The inner hole is formed in the stepped connecting pipe, the outer portion of the stepped connecting pipe comprises a large excircle and a small excircle, the stepped connecting pipe is traditional, and when forging is conducted, the large excircle and the small excircle are finally required to be subjected to primary reaming respectively.

SUMMERY OF THE UTILITY MODEL

The applicant carries out research and improvement aiming at the defects and provides a hole expanding tool for a stepped connecting pipe.

The utility model discloses the technical scheme who adopts as follows:

the utility model provides a reaming frock for step is taken over, includes that saddle, reaming plug and step go up the hammering block, the reaming plug is arranged in on the saddle, the hammering block is located the saddle top on the step, the hammering block includes the upper padding plate on the step, the upper padding plate below cooperation step is taken over the little excircle and is connected flat hammering block, the upper padding plate still sets up the connecting hole that is used for connecting the press.

As a further improvement of the above technical solution:

and the upper flat anvil is welded with the upper backing plate.

And notches filled with welding fluxes are cut on two sides of the upper end of the upper flat anvil.

And two sides of the lower end of the upper flat anvil are processed into round corners.

The utility model has the advantages as follows: a reaming frock for step is taken over through setting up the bench anvil, can advance big excircle and little excircle reaming simultaneously, and the reaming is the straight hole, and product quality is good, and reaming machining efficiency is high.

Drawings

Fig. 1 is the utility model provides a processing schematic diagram of a reaming frock for step is taken over.

Figure 2 is the utility model provides a side view that is used for reaming frock step upper anvil of step-shaped takeover.

Figure 3 is the utility model provides a bottom view of anvil on reaming frock step for step is taken over.

In the figure: 1. a horse frame; 2. reaming the core rod; 3. an upper anvil of the step; 31. an upper base plate; 311. connecting holes; 32. and (4) an upper flat anvil.

Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

As shown in fig. 1 to 3, the reaming tool for a stepped pipe of the present embodiment includes a trestle 1, a reaming mandrel 2 and a step upper anvil 3, the reaming mandrel 2 is disposed on the trestle 1, the step upper anvil 3 is disposed above the trestle 1, the step upper anvil 3 includes an upper pad plate 31, a small outer circle of the stepped pipe is matched below the upper pad plate 31 and is welded to the upper flat anvil 32, two sides of the upper end of the upper flat anvil 32 are cut to form unfilled corners filled with solder, so as to improve the welding strength, two sides of the lower end of the upper flat anvil 32 are processed to form rounded corners, and the upper pad plate 31 is further provided with a connecting hole 311 for connecting a lifting driving component.

When the chambering tool for the stepped connecting pipe is used, a bolt penetrates through the connecting hole 311 to fixedly connect the upper anvil 3 of the step with the press, then the stepped connecting pipe is sleeved on the chambering core rod 2, then the chambering core rod 2 is arranged on the saddle 1 below the press, the chambering core rod 2 rotates, meanwhile, the press drives the upper anvil 3 of the step to descend, when the forging is started, due to the material distribution requirement, the height difference between the large outer circle and the small outer circle of the stepped connecting pipe is larger than the thickness of the upper anvil 3 of the step, so the upper cushion plate 31 is firstly contacted with the large outer circle, the large outer circle is firstly stressed to chambering, the chambering is carried out for a period of time, the diameter of the inner hole is continuously enlarged, the height difference between the large outer circle and the small outer circle is reduced, the upper flat anvil 32 is also pressed on the small outer circle, the large outer circle and the small outer circle are simultaneously, and taking the step-shaped connecting pipe off the reaming core rod 2.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
