Description

A chain link hook production device

technical field

The utility model relates to a production device, in particular to a chain link hook production device, which belongs to the technical field of mechanical processing.

Background technique

With the progress of large-scale infrastructure construction in the country, the use of bucket elevators, an important equipment for cement production, continues to expand, and the demand for chain link hooks, an important part of them, is increasing day by day. The current domestic production process of chain link hooks is: blanking-weaving U-ring-braiding-machining-heat treatment-inspection-asphalt dipping. At present, most manufacturers adopt backward production technology. Generally, U-rings are compiled first, then the mold is replaced, and then formed into shapes. After two processes. This operation has the following disadvantages: low efficiency, generally 2 to 3 people are required to operate the process, and two processes are required, especially the mold needs to be replaced, and debugging is required before production, which not only wastes raw materials, but also has very low efficiency and ugly appearance ; In addition, because the workers in the two processes use special tools to place the semi-finished products of the previous process on the mold, it is inevitable that the position of the placement is not accurate, so that the quality is difficult to guarantee; because the production method has to go through two cold extrusion processes, processing The stress is relatively large, which is prone to work hardening. Therefore, for the above situation, it is very necessary to study a kind of device for producing chain link hooks with high efficiency.

Utility model content

In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a link hook production device capable of producing link hooks with high efficiency, high quality and low cost, so as to meet the needs of industrial production.

For solving the problems of the technologies described above, the technical scheme that the utility model takes is as follows:

A chain link hook production device, including an upper mold device and a lower mold device, the lower mold device includes a bottom plate, two vertically fixed support frames are arranged on the bottom plate, and a cross-shaped top pressure block is arranged under the bottom plate. A spring I is arranged between the briquetting block and the support frame, a rotary mold base is arranged on the bottom plate, a rotary mold is fixedly arranged on the rotary mold base through a pin shaft, a roller is arranged in the rotary mold, and a spring is arranged between the rotary mold and the supporting plate. II. The upper die device includes a U-shaped die handle and an upper die fixed on the die handle, and the formed workpiece is located between the upper die and the rotary die.

As a further preferred solution, the support frame is also provided with adjustment screws.

As a further preferred solution, the bottom plate is fixed on the workbench of the press.

Compared with the prior art, since the mold of the utility model is divided into upper and lower molds, which are fixed on the open press, the opening degree of the lower mold can be adjusted. Therefore, the utility model can complete the production and molding of the chain link hook in one process. , the structural design is simple and reasonable, and the semi-automatic operation is used to produce and shape the chain link hook, which solves the problem of low production efficiency of the chain link hook, and ensures the quality of the finished product, and has good industrial application value.

Fig. 2 is a structural schematic diagram of the chain link hook described in the utility model.

Detailed ways

Below in conjunction with accompanying drawing and embodiment thereof, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a chain link hook production device provided by the utility model includes an upper mold device and a lower mold device, and the lower mold device includes a base plate 1, and the base plate 1 is provided with two vertically fixed supports Frame 3, bottom plate 1 is also provided with cross-shaped top press block 13, is provided with spring I 14 between top press block 13 and bracing frame 3, and base plate 1 is provided with rotary mold base 12, and on rotary mold base 12, passes Pin shaft 10 is fixedly provided with rotary mold 2, and roller 9 is arranged in rotary mold 2, and spring II4 is arranged between rotary mold 2 and support plate 3, and upper mold device 15 includes U-shaped mold handle 7 and is fixed on mold handle 7. The upper die 8 on the top, the forming workpiece 11 is located between the upper die 8 and the rotary die 2, the support frame 3 is also provided with an adjusting screw 6, the blank workpiece 5 is located between the two adjusting screws 6, and the bottom plate 1 is fixed on the bottom of the press. on the workbench.

The operating method of using the utility model to produce chain link hooks includes the following steps: 1) start the press; 2) accurately place a round bar on the roller of the lower die; 3) step on the foot switch of the press , the upper die moves downward under the drive of the crank slider mechanism of the press, punches the round bar blank, and finally bends the blank, pay attention to lift the foot immediately after the clutch of the press is opened; 4) After the above process is completed, the press slides The block is at the bottom dead point. Due to the inertia, the upper die and the die handle return to the top dead point together with the press slider. The tension spring makes the rotary die return to the initial state, and the top pressure block rebounds under the action of the compression spring. Go to the original position; 5) Take out the molded chain link hook molding workpiece with a special fixture and put it in a special semi-finished turnover box.

Because the mold of the utility model is divided into upper and lower molds, which are fixed on the open press, and the opening degree of the lower mold can be adjusted, therefore, the production and molding of the chain link hook can be completed in one process by using the utility model, and its structural design is simple and reasonable , using semi-automatic operation to produce and shape the chain link hook, which solves the problem of low production efficiency of the chain link hook, and ensures the quality of the finished product, which has good industrial application value.

At last it is necessary to point out that: the above embodiments are only used to further describe the utility model in detail, and cannot be interpreted as limiting the protection scope of the utility model. Essential improvements and adjustments all belong to the protection scope of the present utility model.
