Description

Technical Field

[0001] The utility model relates to the technical field of automated processing, in particular to a thread rolling processing line. Background Art

[0002] The thread rolling machine is an existing production equipment, and its function is to complete the thread rolling process of the workpiece. However, in the actual production process, the processing of the workpiece is not simply to put the workpiece into the thread rolling machine, but also requires the cooperation of multiple working links. For example, in the processing of the screw rod, the raw materials of the screw rod need to be placed in the corresponding processing area according to different processing links. After the processing of each area is completed, the workpiece is collected into a temporary material box using the material receiving structure, and then the staff collects the processed workpieces and puts them in a trolley, and transports them in different working areas to complete each process one by one.

[0003] At present, the execution of each of the above processes is carried out independently. When a process is completed, the workpiece is transferred to another processing position for the next processing. This processing method is inefficient. In addition to requiring staff for each process, the transfer of workpieces between the workstations of each process may cause the workpiece to be bumped and damaged, thereby damaging the workpiece, reducing the yield rate, and affecting the processing quality.

The production line of this solution forms a flow-type production and processing mode, getting rid of the problem of accumulating workpieces and then transferring them uniformly in the original production and processing mode, thereby avoiding the situation where the workpiece is damaged during the turnover process. The production line of this solution can improve the processing efficiency and the processing quality at the same time.

[0047] Based on the above implementation scheme, the processing stations of the intermediate processing unit 3 include a first station 31 and a second station 32, both of which are equipped with CNC lathes, wherein the first station 31 is used for primary processing of the workpiece; the second station 32 is used for secondary processing of the workpiece.

[0048] The intermediate processing unit 3 uses a set of first workstations 31 and second workstations 32 as a processing area of ​​the intermediate processing unit 3. This combination method is used to divide the intermediate processing unit 3 into a first half area and a second half area. Each half area includes a first workstation 31 and a second workstation 32.

[0049] For the processing of the screw rod, in addition to the first thread rolling unit 1 and the second thread rolling unit 2 as the main processing steps, other processing links are required.
