Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic scissor bending equipment, specifically a pneumatic scissor bending device. Background Technology

[0002] Pneumatic shearing and bending equipment is a practical machining device that combines pneumatic technology with the functions of bending and shearing. It can automatically bend and cut the pins of parts. Pneumatic shearing and bending equipment is widely used in the processing of parts in the fields of electronics, communications, automobiles, and aerospace. Especially for parts that require precise bending and cutting of pins, this equipment has significant advantages and application value.

[0003] Most of the devices require manual, step-by-step processing, including cutting and bending, and workers need to process each pin individually. The devices also need to be collected later, which is not only time-consuming and labor-intensive but also inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatic shear bending device that reasonably solves the problem that most devices require manual step-by-step processing, first shearing and then bending, and requires construction personnel to process each pin one by one, and then collect the data later. This is not only time-consuming and labor-intensive, but also inefficient, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic scissor bending device, comprising a base plate, a transmission component with clamping and conveying function fixedly installed on the base plate, a bending component with bending function fixedly installed on the base plate, the transmission component including a conveyor belt, a first fixing block fixedly installed at the lower end of the conveyor belt, a partition fixedly installed at the lower end of the first fixing block, springs fixedly installed on both sides of the partition, clamps fixedly installed on one side of each spring, the bending component including a pneumatic cylinder, a push plate fixedly installed at the output end of the pneumatic cylinder, a scissor block fixedly installed on one side of the push plate, a movable bending device fixedly installed on the other side of the push plate, an adjusting plate installed at the lower end of the movable bending device, a fixed bending device fixedly installed on the adjusting plate, and guide plates installed on both sides of the adjusting plate.

[0006] Preferably, column legs are fixedly installed around the base plate, and the transmission component is fixedly installed on the column legs for fixation. A triangular protrusion is fixedly installed between the column legs on one side.

[0007] Preferably, a collection box is fixedly installed on the base plate for storing the processed pins.

[0008] Preferably, a scissor block is also fixedly installed on one side of the base plate. The base plate has a groove located between the scissor block installed on the push plate and the scissor block installed on the base plate, which is used to connect with the first slider provided at the lower end of the scissor block installed on the push plate for sliding.

[0009] Preferably, a pull rod is fixedly installed on one side of the adjustment plate, and a slot is provided on one side of the guide plate for the pull rod to move.

[0010] Preferably, the push plate passes through the movable bending device and the adjusting plate on one side, so that when the fixed bending device and the movable bending device are moved by the pull rod, it will not hinder the push plate from pushing the movable bending device toward the fixed bending device.

[0011] Preferably, the adjustment plate has grooves a on both sides, located between the movable bending device and the fixed bending device, and the fixed bending device has second sliders on both sides of its lower end for sliding connection with the grooves a to assist the movable bending device in moving.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Workers place the pins into the clamps and clamp them. The pins are then transported by a conveyor belt. A pneumatic cylinder drives a push plate, moving it back and forth, which in turn moves a shearing block. This shearing block, mounted on one side of the base plate, trims any excess pins. A groove on the base plate connects to the shearing block mounted on the push plate, allowing it to slide and assist the shearing block's movement. Simultaneously, the push plate drives a moving bending device to move and bend the pins. This bending device slides through the groove, assisting the moving bending device in bending the pins. When the processed pins are moved by the conveyor belt, the clamps touch the triangular protrusions, causing elastic deformation through a spring. The clamps release, and the pins automatically fall to the base plate, where a collection box is fixed to store the processed pins. This eliminates the need for manual collection and effectively solves the problem of most devices requiring manual, step-by-step processing—cutting and bending each pin individually, followed by collection—which is time-consuming, labor-intensive, and inefficient.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a pneumatic scissor bending device, including a base plate 1, a transmission component 2 with clamping and transmission function fixedly installed on the base plate 1, a bending component 3 with bending function fixedly installed on the base plate 1, and column legs 101 fixedly installed on all four sides of the base plate 1. The transmission component 2 is fixedly installed on the column legs 101 for fixation.

[0022] The transmission component 2 includes a conveyor belt 201 for transmitting pins. A first fixing block 202 is fixedly installed at the lower end of the conveyor belt 201 for fixing. A partition 203 is fixedly installed at the lower end of the first fixing block 202 for fixing. Springs 204 are fixedly installed on both sides of the partition 203 for elastic deformation during operation. A clamp 205 is fixedly installed on one side of each spring 204 for workers to place and clamp the pins to prevent them from falling off during movement. A triangular protrusion 102 is fixedly installed between the column legs 101 on one side. When the processed pins fixed on the 205 are moved by the conveyor belt 201, the clamp 205 touches the triangular protrusion 102, and the springs 204 undergo elastic deformation. The clamp 205 is released, and the pins automatically fall to the bottom plate 1. A collection box 103 is fixedly installed on the bottom plate 1 for storing the processed pins, eliminating the need for manual collection.

[0023] The bending assembly 3 includes a pneumatic cylinder 301, which provides power to push back and forth, causing a push plate 302 fixedly mounted on the output end of the pneumatic cylinder 301 to move back and forth. This causes a scissor block 303 fixedly mounted on one side of the push plate 302 to move, and a scissor block 303 fixedly mounted on one side of the base plate 1 to trim excess parts of the pin. The base plate 1 has a groove between the scissor block 303 mounted on the push plate 302 and the scissor block 303 mounted on the base plate 1, which is connected to a first slider 304 at the lower end of the scissor block 303 mounted on the push plate 302 for sliding and assisting the movement of the scissor block 303. At the same time, a movable bending device 305 is fixedly mounted on the other side of the push plate 302, which drives the movable bending device 305 to bend the pin. An adjustment plate 307 is installed at the lower end of the movable bending device 305 to adjust the height when bending the pin. The device is equipped with a fixed bending device 306 for bending the pins. Guide plates 308 are installed on both sides of the adjusting plate 307 to guide the moving bending device 305 and the fixed bending device 306 when adjusting their height, preventing them from shifting during movement. A pull rod 309 is fixedly installed on one side of the adjusting plate 307 for pulling. A slot is provided on one side of the guide plate 308 to allow the pull rod 309 to move. A push plate 302 passes through the moving bending device 305 and the adjusting plate 307. When the fixed bending device 306 and the moving bending device 305 are moved by the pull rod 309, it will not hinder the push plate 302 from pushing the moving bending device 305 toward the fixed bending device 306. The adjusting plate 307 has grooves 310 on both sides located between the moving bending device 305 and the fixed bending device 306. The lower ends of the fixed bending device 306 have second sliders 311 on both sides for sliding connection with the grooves 310 to assist the moving bending device 305 in moving.

[0024] Working principle: The worker places the pin into the clamp 205 for clamping. The pin is transported by the conveyor belt 201. The pneumatic cylinder 301 drives the push plate 302 to move back and forth, thereby driving the shear block 303 to move. The shear block 303 installed on one side of the base plate 1 trims the excess part of the pin. The base plate 1 has a groove between the shear block 303 installed on the push plate 302 and the shear block 303 installed on the base plate 1. It is used to connect with the first slider 304 at the lower end of the shear block 303 installed on the push plate 302 for sliding and assisting the movement of the shear block 303. At the same time, the push plate 302 also drives the moving bending device 305 to move the fixed bending device 306 to bend the pin. The adjusting plate 307, through the guide plates 308 on both sides, adjusts the moving bending device. When adjusting the height of the bending device 305 and the fixed bending device 306, they are guided to prevent deviation during movement. The push plate 302 passes through the moving bending device 305 and the adjusting plate 307 on one side. When the fixed bending device 306 and the moving bending device 305 are moved by the pull rod 309, it will not hinder the push plate 302 from pushing the moving bending device 305 toward the fixed bending device 306. The moving bending device 305 is assisted to move by the sliding connection through the groove 310 to bend the pin. When the processed pin fixed on 205 is moved by the conveyor belt 201, the clamp 205 touches the triangular protrusion 102. The spring 204 causes elastic deformation, the clamp 205 is released, and the pin automatically falls to the bottom plate 1. A collection box 103 is fixedly installed to store the processed pin, eliminating the need for manual collection.
