Description

Single guide post punching device

                    

The utility model relates to a single guide column punching device, which belongs to the manufacture of cold stamping die processing equipment

technology field.

Background technique

The punching device in the existing punching die processing equipment is generally made up of upper and lower layers of mold bases, one deck of mold bases is equipped with guide pillars, and one deck of mold bases is equipped with guide sleeves. A set of mold bases must have at least 2 guide pillars and 2 guide sleeves. The separate settings of the upper and lower mold bases are prone to processing and assembly deviations and resulting in accumulated errors. Moreover, the structure is huge and time-consuming to install. In addition, after the punch and die are worn out, it is troublesome to disassemble and assemble, which also affects the positioning accuracy, and the common rate of the mold base is low, which affects the processing quality and work efficiency.

Contents of the invention

The purpose of the utility model is to provide a single guide post punching device with reasonable design, simple structure, convenient installation, high mold base universality, and flexible combination to meet different punching requirements.

The utility model is a punching device for a single guide post, which includes an upper mold base and a lower mold base, and is characterized in that the upper mold base and the lower mold base are integral "C"-shaped structures, and the upper mold base is provided with A guide sleeve and a pressing plate with a pressing plate spring, a guide post with a punch is arranged under the pressing plate; a discharge plate is provided on the lower part of the upper die base, and a discharge plate is placed on the lower part of the pressing plate spring; the lower die base There is a die on it. When working, different die holders can be installed according to the punching requirements, and the pressure plate can be moved downward through the pressure mechanism, driving the guide post and the punch to move down along the guide sleeve, so that the punch enters the die to complete the punching.

The punch can be fixedly connected with the pressure plate by a guide post screw placed in the middle of the guide post.

The die can be fixedly connected with the lower die base by a tight ring and bolts.

The stripper plate can be fixedly connected by a stripper plate screw with a stripper plate spring placed in the upper mold base.

Positioning pins can also be provided on the lower mold base. It is convenient to position and fix the utility model on the die processing equipment.

The utility model has a reasonable design, and the integral "C" structure of the upper mold base and the lower mold base can precisely position the punch and the die, so that the relative positions of the punch and the die do not need to be adjusted when they are installed. The positioning accuracy is high, and the punch and die are easy to disassemble after wear. It effectively avoids processing and assembly deviations and accumulated errors, improves the common rate of mold bases, and also improves the processing quality and work efficiency of punching. The utility model can be matched and used on die processing equipment for metal or non-metal materials.

Detailed ways

The utility model is mainly composed of an upper mold base 8 and a lower mold base 11 with an integral "C" structure, a guide sleeve 5 placed on the upper mold base 8, a pressure plate 1 with a pressure plate spring 4, and a convex plate under the pressure plate 1. The guide post 3 of the mold 6, the stripping plate 7 placed on the lower part of the upper mold base 8, the die 10 placed on the lower mold base 11 and the positioning pin 12 etc. constitute. The lower part of the pressure plate spring 4 is placed on the unloading plate 7, and the unloading plate 7 is fixedly connected by the unloading plate screw 13 with the unloading plate spring 14 placed in the upper die base 8; The guide post screw 2 is fixedly connected with the pressing plate 1; the die 10 is fixedly connected with the lower mold base 11 through the tight ring 9 and the bolt 15.

When in use, the utility model is positioned and fixed on the die processing equipment. When working, the pressure mechanism transmits the pressure to the pressure plate 1, and the pressure plate 1 drives the guide post 3 and the punch 6 to slide downward in the guide sleeve 5, and simultaneously drives the stripper plate 7 and the stripper plate screw 13 to move downward. The stripper plate spring 14 is compressed when the stripper plate screw 13 is moved down. When the unloading plate 7 is pressed against the part, the unloading plate 7 does not move, and the pressing plate 1 continues to drive the guide column 3 and the punch 6 to move downward until the hole is punched out, and the pressing plate spring 4 is compressed at the same time. After punching, the pressure mechanism moves upwards, pushes the pressing plate 1 upwards under the elastic force of the pressing plate spring 4, the pressing plate 1 drives the guide post 3 to move upwards, and the punch 6 retracts into the unloading plate 7 to complete the unloading. Under the elastic force of the stripping plate spring 14, the stripping plate screw 13 is driven to move up, and at the same time, the stripping plate screw 13 drives the stripping plate 7 to move back to the original position, and a working cycle is completed.
