Problems solved by technology

[0002] The traditional production methods of shackles are: free forging and die forging, through upsetting, elongation, indentation, ball shackle shape, middle elongation, flattening, punching, bending, correction, etc. It has the following problems: A. Low production efficiency and high labor intensity; B. Great noise pollution during hammer forging; C. The produced products have rough appearance and poor dimensional accuracy; D. The utilization rate of materials is low. Low; E, relatively high cost
In addition, since the production of this product has been produced by the hammer forging process, there is no related pressing die

Embodiment 1

[0017] For the production of A-type straight anchor shackles (A-type straight anchor shackles: 3.5≤λ≤5.5; λ is the ratio of the length of the workpiece aggregated into a ball and the diameter of the workpiece, the same below).

[0018] The first step is to prepare materials. According to the specifications of the shackles, select the corresponding round steel billets.

[0019] The second step is to gather materials, heat one end of the round steel billet to keep its temperature at 750-1220°C, and put it into the pressing mold. The mold of this embodiment is as figure 1 , 2 As shown, the mold is composed of an upper mold 1 and a lower mold 2, wherein the upper mold 1 is connected with the pressing rod 30 of the pressing equipment, and the left and right opening and closing lower mold 2 is connected with the clamping mechanisms 29 on both sides; its specific structure is The upper mold 1 is formed by a cone-like cavity 6 in the center of the lower end face of the cylindrical m...

Embodiment 2

[0025] For the production of Class B straight anchor shackles (3.0≤λ≤4.5), the process is basically the same as in Example 1: the first step is to prepare materials; the second step is to gather materials; the third step is to form balls; the fourth step is The sphere is flattened; the fifth step is to form a hole; the sixth step is to bend. Among them, because λ is relatively small, the aggregate is used as Figure 5 The specific structure and aggregate action of the mold shown are as follows: the upper mold 19 is formed by a cone-like cavity 21 in the center of the lower end surface of the cylindrical metal block 20; the lower mold 22 is composed of left and right opening and closing molds 23 with the same structure , 24 combined, when the lower mold 22 is closed as a whole, the center of the upper end surface of the cylindrical metal block 25 is formed by a hemispherical cavity 26 and a cylindrical hole 27 opened through the metal block at the center of the bottom end of th...

Embodiment 3

[0027] For the production of Type C straight anchor shackles (λ≤3.5), the specific implementation method is the same as that of Example 1. Since its λ is very small, it is only necessary to directly ball the two ends of the round steel billet. The following steps are required for the type anchor shackle: the first step is to prepare the material; the second step is to form a ball; the third step is to flatten the sphere; the fourth step is to form a hole; the fifth step is to bend. Due to the direct ball forming, the selected pressing die is Figure 4 The mold shown, its structure and ball forming action have been stated in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to a hot die-pressing production technique of a shackle and a die thereof. The invention selects round steel blank, adopts pressing technique to produce the shackle by using the die, greatly reduces labor intensity of workers and noise pollution, obviously improves product quality and production efficiency compared with the traditional hammer forging production technique, saves production cost and is beneficial to realizing automation of the production process. Aiming at realizing the convergence of round steel blank at two ends and ball forming in hot die-pressing forming technique smoothly, a die is also used and comprises an upper die and a lower die; the upper die is formed by a cavity with an opening on the lower end surface, the lower die consists of a left opening die and a right opening die which have same structure, and can be opened and closed; and when the left opening die and the right opening die are closed, a cavity which is communicated with the upper part and the lower part of the lower die is formed.

Description

technical field [0001] The invention relates to a shackle thermal molding production process, and also relates to the hydraulic mold used in the shackle thermal molding production process. Background technique [0002] The traditional production methods of shackles are: free forging and die forging, through upsetting, elongation, indentation, ball shackle shape, middle elongation, flattening, punching, bending, correction, etc. It has the following problems: A. Low production efficiency and high labor intensity; B. Great noise pollution during hammer forging; C. The produced products have rough appearance and poor dimensional accuracy; D. The utilization rate of materials is low. Low; E. The cost is relatively high. In addition, since the production of this product has been produced by the hammer forging process, there is no related pressing die. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shackle hot mol...
