Technical Field

The invention belongs to the technical field of nut closing devices, and particularly relates to a nut taper closing device capable of automatically discharging.

Background

Self-locking nuts are very common in the production process, and the taper closing-in is the main closing-in mode of the slotted self-locking nut. The closing-up surface of the traditional slotted self-locking nut has a certain taper (such as HB8045 and HB 8049), and the unloading is convenient during closing-up. With the updating of products, some slotted self-locking nuts (such as Q/S15.1084-5) with non-taper closing surfaces appear, the unloading of the nuts in the closing process is difficult, and sometimes the closed products can be taken down by using pliers, which seriously affects the processing efficiency of the products, prolongs the processing period of the products, and is easy to damage the slotted self-locking nuts.

Disclosure of Invention

The invention aims to overcome the defects and provide the nut taper closing device which has the advantages of simple structure, convenience and quickness in operation, high efficiency, stability, high quality and reliability and can automatically unload materials.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention discloses a nut taper closing device capable of automatically discharging, which comprises an ejector rod, a press machine and a closing female die, wherein: the press machine is fixedly connected with the closing-in female die, a through hole is formed in the closing-in female die, the ejector rod is arranged in the through hole, a spring is sleeved on the upper portion of the ejector rod, two ends of the spring are respectively pressed at the top of the closing-in female die and the lower end of the head of the ejector rod, a pressure workbench is arranged below the closing-in female die, a positioning pin is arranged on the pressure workbench, and the positioning pin is arranged under the.

Above-mentioned but nut tapering binding off device of automatic discharge, wherein: the through hole is composed of a straight cylindrical section at the head and a conical section at the tail.

Compared with the prior art, the invention has obvious advantages and beneficial effects. According to the technical scheme, in the nut taper necking device capable of automatically discharging, the press machine is fixedly connected with the necking female die, so that the necking female die is driven to ascend and descend by the press machine, and the functions of stamping and discharging are realized; a through hole is formed in the closing-up female die, the ejector rod is arranged in the through hole, a spring is sleeved on the upper portion of the ejector rod, two ends of the spring are respectively pressed at the top of the closing-up female die and the lower end of the head of the ejector rod, so that the ejection and unloading of a product can be conveniently carried out through the ejector rod, and the ejector rod returns under the action of the spring; a pressure workbench is arranged below the necking female die, a positioning pin is arranged on the pressure workbench and is arranged right below the through hole, and the positioning pin is used for positioning the nut to be subjected to necking, so that the operation is stable and reliable; the through hole is composed of a straight cylindrical section at the head and a conical section at the tail, and the conical section realizes punching and closing of a product. In a word, the automatic discharging and closing device is simple in structure, convenient to operate, efficient, stable, high-quality and reliable, and suitable for popularization and use of automatic discharging and closing of the slotted self-locking nut.

Detailed Description

The following detailed description of the embodiments, structures, features and effects of the tapered nut necking device for automatically discharging according to the present invention will be made with reference to the accompanying drawings and the preferred embodiments.

Referring to fig. 1, the nut taper closing device capable of automatically discharging comprises an ejector rod 1, a press machine 3 and a closing female die 4, wherein: the press machine 3 is fixedly connected with the closing-in female die 4, a through hole 5 is formed in the closing-in female die 4, the ejector rod 1 is arranged in the through hole 5, the spring 2 is sleeved on the upper portion of the ejector rod 1, two ends of the spring 2 are respectively pressed at the top of the closing-in female die 4 and the lower end of the head of the ejector rod 1, the pressure workbench 7 is installed below the closing-in female die 4, the positioning pin 6 is installed on the pressure workbench 7, and the positioning pin 6 is arranged under the through. The through hole 5 consists of a straight cylindrical section at the head and a conical section at the tail.

During the use, adjust the stroke of press 3 according to the demand, the fluting self-locking nut that will treat the binding off is installed on pressure workstation 7 and is fixed a position through locating pin 6, start press 3 and push down the fluting self-locking nut that treats the binding off and carry out the punching press binding off, binding off back fluting self-locking nut can press the toper section of binding off die 4 and move along vertical direction together, when reacing preset's maximum stroke department, ejector pin 1 contacts with the stripper of fixing on the organism, produce the power of unloading, under the effect of the power of unloading, the fluting self-locking nut separates with binding off die 4, when the press leaves maximum stroke position downstream, ejector pin 1 resumes original position under spring 2's effect, realize tapering binding off automatic discharge. The automatic discharging and closing device is simple in structure, convenient to operate, efficient, stable, high in quality, reliable and suitable for popularization and use of automatic discharging and closing of the slotted self-locking nut.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are within the scope of the present invention without departing from the technical spirit of the present invention.
