Description

Upset head mechanism of open-close type two-way motion

Technical Field

The utility model relates to a heading mechanism device capable of automatically opening and closing and moving in two directions, in particular to a heading die device suitable for small double-crown blade forgings.

Background

The double-shroud blade of the compressor generally comprises a blade root, a blade shroud and a blade body, and the cross section areas of the blade root and the blade shroud are larger than that of the blade body. Due to the structural characteristics, two-end upsetting blank making is generally required before forging products. According to the principle that the volume of a forging process is not changed, materials required by the process need to be designed and reserved at a position with a large volume, and step-by-step upsetting needs to be used in the process because an original blank is a bar with an equal section. The conventional upsetting die is manually operated at present, the upsetting process has large workload and low working efficiency due to the complexity of the structure, and the upsetting die is easy to expand and die due to blank deformation along with the increase of the production quantity. In order to solve the problem, a brand new die mechanism needs to be designed on the basis of applicable equipment and motion mechanism so as to reduce the operation difficulty and greatly improve the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an upsetting mechanism device capable of automatically opening and closing two-way movement aiming at the problems of complex product structure and high operation difficulty, so that the operation difficulty is greatly reduced.

The utility model provides an upset head mechanism of open-close type two direction motions which characterized in that: the device comprises a guide rail base, wherein a fixed half mold is installed at one end of the guide rail base, a lateral half mold is installed on a guide rail at the other end in a sliding manner, and cavities which can be matched with each other are respectively arranged on opposite surfaces of the fixed half mold and the lateral half mold; and a punch press plate is arranged above the lateral half-die and is arranged on the top surface of the upper machine, and the opposite surfaces of the punch press plate and the lateral half-die are set to be wedge surfaces.

It is further characterized in that:

a limiting plate is mounted at the other end of the guide rail base and arranged on the outer side of the lateral half mold;

Detailed Description

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the embodiments described herein are illustrative of the utility model and are not to be construed as limiting the utility model.

An open-close type heading mechanism moving in two directions comprises a guide rail base 11, wherein one end of the guide rail base 11 is provided with a fixed half mold 8, a guide rail at the other end is provided with a lateral half mold 3 in a sliding way, and opposite surfaces of the fixed half mold 8 and the lateral half mold 3 are respectively provided with a cavity capable of being matched; a punch press plate 2 is arranged above the lateral half-mold 3, the punch press plate 2 is arranged on the upper machine table board 1, and the opposite surfaces of the punch press plate 2 and the lateral half-mold 3 are wedge surfaces. A limiting plate 4 is arranged at the other end of the guide rail base 11, and the limiting plate 4 is arranged outside the lateral half-mold 3; a return spring 9 is pressed between the lateral half mold 3 and one end of the guide rail base 11, and the spring is sleeved outside a return bolt 10; the guide rail base 11 is installed on the die holder 6 through the transition plate 5, and the die holder 6 is installed on the lower machine table surface 7.

In the present embodiment, as shown in fig. 1, it is a schematic diagram of the use of the heading machine of the present invention; FIGS. 2-5 are schematic views of the heading process of the present invention; fig. 6 is a schematic diagram of the backhaul of the present invention. As shown in figure 1, the device is arranged on an upper machine table surface 7 and a lower machine table surface 7 of equipment, a die holder 6 is assembled and connected with the lower machine table surface 7 through a T-shaped bolt, a punch press plate 2 is connected with an upper machine table surface 1 through a bolt and a transverse groove, a transition plate 5 is respectively connected with a guide rail base 11 and the die holder 6 through a bolt, a fixed half die 8 is connected with the guide rail base 11 through a bolt, and a lateral half die 3 is connected and assembled with the guide rail base 11 through a bolt and a tension spring.

As shown in fig. 2, 3, 4 and 5, the blank is placed longitudinally on the guide rail base 11 and positioned transversely across the cavity-carrying stationary mold half 8. And in the descending process of the equipment, the punch press plate 2 contacts the lateral half mould 3 through the inclined surface to automatically hold the blank in the mould. And the inclined surface contact stops entering the straight surface contact along with the continuous descending of the punch press plate 2, so that the upsetting of the blank in the die cavity and the lateral closing and clasping of the mechanism are completed, and the die is prevented from expanding under the lateral force during the upsetting of the blank. At the moment, the die is in a closed state, the blank is upset, and the tension spring is pressed.

As shown in fig. 6, after the heading is completed, the upward punch press plate 2 of the apparatus moves upward, the lateral half mold 3 is gradually rebounded to the original position under the action of the elastic force of the tension spring, and in order to prevent the lateral half mold from exceeding the original position, a limit plate 4 is arranged on the guide rail base 11. At the moment, the half mold is pulled open to obtain the material. The above operation is repeated to complete the blank preparation.

The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the utility model, which changes and modifications are within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
