Embodiment Construction

[0026] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] refer to Figure 6a and Figure 6b As shown, the convex-concave assembly structure of the jaw body and the jaw insert in this embodiment includes three components: the jaw body, the jaw insert and the fine-tuning bolt. For the convex part, the fine-tuning bolt is screwed into the fine-tuning threaded hole 3 and the jaw insert is tightened with a slight force.

[0028] The jaw body includes three main components: a fixed boss 1, a fixed cavity 2 and a fine-tuning threaded hole 3. The structure is simple and compact, and the strength is sufficient. The fixed boss 1 is located symmetrically in the middle of the fixed cavity 2 of the jaw body. The upper and lower parts of the upper and lower parts are rectangular p...

Abstract

The invention discloses a convex-concave assembling structure of a jaw body and a jaw insert. The structure comprises the jaw body, the jaw insert and a micro-adjustment bolt; the convex portion and the concave portion of the jaw body correspond to the concave portion and the convex portion of the jaw insert correspondingly, and the micro-adjustment bolt is rotated in a micro-adjustment threaded hole in the jaw body to fasten the jaw insert with micro force. The convex-concave assembling structure is simple in structure, the round bar is simple in clamping process, the jaw insert fixed mounting process is simple, the efficiency is high, reliability is high, the service life of the jaw body and the jaw insert is long, the cost is low, and the problem that a jaw body and a jaw insert of an existing horizontal electric heating upsetting machine are not likely to be fixedly assembled, and the service life of the jaw body and the jaw insert is low is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of forging, and relates to a convex-concave assembly structure of a jaw body and a jaw insert. Background technique [0002] The existing D91, D92, D93 and other series of horizontal electric heating upsetting machines (hereinafter collectively referred to as electric heating upsetting machines) are forging equipment that simultaneously completes two working steps of local heating at one end of a round steel bar and collective upsetting. The diameter specification is φ5.0mm~φ35.0mm, and the minimum length of the electrothermal upsetting round bar should be greater than the width of the jaw insert or the length of the jaw body (the width of the jaw insert or the length of the jaw body is basically the same, generally 70mm~92mm ). [0003] Before the electric heating upsetting machine works, the jaw insert is fixedly assembled on the jaw body, and the round bar is clamped on the jaw insert. The jaw body is c...
