Description

Technical Field

[0001] The invention relates to the technical field of rod processing, and in particular to an optimization method suitable for a threaded rod production process. Background Art

[0002] The bars are widely used in many fields such as construction, infrastructure, manufacturing, etc. The company is committed to intelligent manufacturing and uses CNC steel bar processing equipment for fully automatic assembly line production.

[0003] At present, the production process of threaded rods is: rod cutting → upsetting → threading → grinding → material collection. The production cycle of the original process flow was calculated: cutting 2S, upsetting 30S, threading 60-90S, grinding 30S. Among them, the threading process takes the longest time and is the bottleneck process, which seriously reduces the production capacity of rod threading. At the same time, when the rod is threaded, it goes directly to the material collection. Often, the thread end is not protected in time (or the protection method is incorrect), the thread bumps, resulting in thread damage or even scrapping, which greatly affects product quality and rework costs. Summary of the invention

[0004] The purpose of the present invention is to provide an optimization method suitable for the production process of threaded rods, adding a new threading 2 process, a new rubber protective cover process, two new waiting processes, and a new threading 2 process, which can effectively reduce the waiting time of the remaining processes; for the protection of the threaded end, a new protective cover installation process is added to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An optimization method for a threaded bar production process is based on CNC steel bar processing equipment, which sequentially comprises cutting → upsetting → waiting 1 → threading 1 → threading 2 → waiting 2 → grinding head → installing a protective cover → material receiving station, wherein the cutting, upsetting, waiting 1, threading 1, threading 2, waiting 2, and grinding head stations are all equipped with turning rods for lifting the completed bar material into the next process, wherein the upsetting station is provided with two turning rods, one is a short turning rod, and the other is a long turning rod, which can lift the completed upsetting bar material into the waiting 1 and threading 1 processes respectively.

[0006] A further solution of the present invention is that sensors are respectively arranged under threading station 1 and threading station 2. If it is detected that there is no rod at the station, the turning rod of the process will be lifted up first after the upsetting process is completed.

[0007] A further solution of the present invention is that a sensor is arranged under the grinding head station. If it is detected that the grinding head process is working, the turning rod of the threading station 2 and the turning rod of the waiting station 2 will not move; if there is material in the threading station 2 and the waiting station 2 at the same time, the rod of the threading station 2 will be lifted into the grinding head first.

[0008] A further solution of the present invention is that a chain machine is provided at the protective cover installation station, and an array of V-shaped opening stations is provided on the chain machine.

[0009] A further solution of the present invention is that the number of groups of V-shaped mouth workstations is ≥10.

[0010] A further solution of the present invention is that the protective cover installation station is automatically installed by a machine or manually installed.

[0011] A further solution of the present invention is that the protective cover installation station installs a rubber protective cover.

[0012] Beneficial effects of the present invention: The optimization method for the threaded rod production process of the present invention adds a threading 2 process, a rubber protective cover process, two waiting processes, and a threading 2 process, which can effectively reduce the waiting time of the remaining processes; for the protection of the threaded end, a protective cover installation process is added.

[0016] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1: Figures 1 to 3 As shown, an optimization method suitable for the production process of threaded rods is based on CNC steel bar processing equipment, which includes cutting → upsetting → waiting 1 → threading 1 → threading 2 → waiting 2 → grinding head → installing protective cover → material receiving station in sequence. The cutting, upsetting, waiting 1, threading 1, threading 2, waiting 2, and grinding head stations are all equipped with turning rods to lift the completed rods into the next process, among which the upsetting station is provided with two turning rods, one is a short turning rod and the other is a long turning rod, which can lift the completed upsetting rods into the waiting 1 and threading 1 processes respectively.

[0018] Sensors are set under threading station 1 and threading station 2 respectively. If it is detected that there is no bar at the station, the turning rod of the process will be lifted up first after the upsetting process is completed.

[0019] A sensor is set under the grinding head station. If it is detected that the grinding head process is working, the turning rod of the threading station 2 and the turning rod of the waiting station 2 will not move; if there is material in the threading station 2 and the waiting station 2 at the same time, the rod of the threading station 2 will be lifted into the grinding head first.

[0020] The protective cover installation station is provided with a chain machine 3 , and the chain machine 3 is provided with an array of V-shaped mouth stations 301 .

[0021] The number of groups of the V-shaped mouth stations 301 is ≥10.

[0022] The protective cover installation station is for manually installing the rubber protective cover.

[0023] The working principle of the present invention is as follows: like Figures 1-2 As shown, the CNC steel bar processing equipment is equipped with a turning rod at each station, which is used to lift the completed bar into the next process. The upsetting station is designed with two turning rods, one is a long turning rod and the other is a short turning rod, which can lift the bar into the waiting 1 and threading 1 stations respectively. The bar enters the cutting process for fixed-length cutting, and the machine turning rod is lifted to lift the cut bar into the upsetting station. Sensors are set under the threading 1 station and the threading 2 station respectively. If it is detected that there is no bar at the station, the turning rod of the station will be lifted first after the upsetting process is completed. For example: if there is a shortage of material in the threading 2 process, after the upsetting is completed, the short turning rod is lifted first, and the bar enters the waiting 1, and the turning rod of the waiting 1 is lifted, and the bar is lifted into the threading 2 station. When there is no bar at both the threading 1 and threading 2 stations, the short turning rod is lifted first to feed the waiting 1 and threading 2 stations.

[0024] After the threading process is completed, the turning rod lifts the bar into the grinding head station. A sensor is also set under the grinding head station. If it detects that the grinding head process is working, the turning rod of the threading 2 station and the turning rod of the waiting 2 station will not move. If there is material at both the threading 2 station and the waiting 2 station, the bar of the threading 2 station will be lifted into the grinding head first.

[0025] As shown in 3, after the grinding process is completed, the turning rod is lifted and the bar falls into the V-shaped mouth station 301 of the chain machine 3. The chain machine 3 is set with ≥10 stations, which is convenient for employees to put on the rubber protective cover at one time, and increases the employee's fault tolerance rate, preventing employees from not having time to put on the rubber protective cover, and the rubber protective cover and the two ends of the bar have interference fit or thread fit. After all stations on the chain machine 3 are covered with rubber protective covers, the employee presses the release button, and the bar covered with rubber protective covers is transmitted and falls into the receiving hopper.

[0026] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit of the present invention should be included in the protection scope of the present invention.
