Detailed Description

The present application is described in further detail below with reference to fig. 1.

The embodiment of the application discloses a processing technology of a sealing strip framework.

The automobile sealing strip framework is characterized in that steel strips are usually subjected to processes of hobbing, stretching and the like, then finished products are rolled and sent to a process to be further processed, in the sealing strip framework in the related technology, some steel strips with short lengths cannot be processed and utilized due to the short lengths, and the steel strips with short lengths are directly sent to waste products to be melted and reused according to the waste products. The short steel belts are processed through all the procedures of the sealing strip framework processing, and the short steel belts are directly processed according to waste products, so that the processing procedures and working hours which are processed in front of the steel belts are wasted, raw materials and working hours are wasted, the utilization rate of the raw materials is low, and the production cost is high.

Referring to fig. 1, a processing technology of a sealing strip framework comprises the following steps:

a. feeding; the working personnel transfers the material tray to the material supporting chuck, then fixes the material tray on the material supporting chuck, and then pushes the material tray to a working position; before feeding, staff check equipment first, carry out security inspection and functional inspection.

The safety inspection comprises whether the crane steel chain is intact and whether the safety buckle of the crane chain is in a locking position. Checking whether the locking handle can be freely loosened or not when the crane runs up and down normally; when the staff carries out functional inspection, the start pedal needs to be guided down, the start guard bar is guided by hands, the start guide bar rotates 180 degrees, and whether the positioning of the two stations is intact is inspected. The staff need ensure that loop wheel machine equipment can normal operating, guarantees near staff's personal safety.

The raw material needs to be inspected after the inspection of the equipment is completed, and the worker needs to inspect the surface, edges, geometric dimensions, and the like of the raw material steel strip. The surface of the steel belt should have no oxidation color, no concave surface, no indentation, no air hole, no pulling crack and individual scab, no micro scratch exceeding half of the thickness tolerance, and no overweight antirust oil; the edge of the steel belt has no cracked edge, no sawtooth and no torn rough burr; when checking the geometric dimension of the steel strip, a worker should use a digital display micrometer to measure the thickness of the steel strip and use the digital display micrometer to measure the width of the steel strip. Unqualified steel strips are removed after the worker checks, and qualified steel strips are sent to the next procedure, so that the phenomenon that finished products are unqualified due to disqualification of raw materials is avoided, and waste of materials and working hours is avoided.

After the worker examines the raw materials, the qualified material disc is hoisted to a specified position by using the hoisting mechanism, when the worker hoists the material disc, the worker examines whether the spiral direction of the material disc is clockwise spiral, otherwise, the material disc needs to be put down, the direction of the material disc is adjusted, after the worker hoists the material disc, the worker detects a steel belt with an inner ring pasted with a double-sided adhesive, and when the worker hoists the material disc, the worker firstly shears a packing belt and then hoists the steel belt so as to prevent the material disc from being scattered, and the workers and materials nearby are protected. After the staff installed the charging tray, the lifting hook withdrawed from and placed the lifting hook inside waiting to lift by crane the plate core of charging tray, avoided the lifting hook drift to appear, avoided the lifting hook to rock near the staff that damages.

b. Removing oil; conveying the raw materials to a front oil remover for first oil removal, and conveying the raw materials to a rear oil remover for second oil removal; the staff will regularly inspect the deoiling cloth in the front oil remover and the back oil remover when deoiling, when the deoiling cloth is dirty or is full of antirust oil, the staff needs to change the new deoiling cloth, the phenomenon that the front oil remover and the back oil remover are not completely deoiled is avoided, and therefore subsequent hobbing processing is facilitated.

c. Performing rolling cutting processing; conveying the raw materials to a machine room, and enabling the raw materials to pass through a material inlet of the machine room for rolling cutting;

d. welding steel strips; the workers weld the short steel strips together after the rolling cutting;

the working personnel collect some short leftover bits of length, trim the terminal surface of leftover bits, make the terminal surface of leftover bits cut off straightly, make the section can not crooked, later will need the welding steel band centre gripping together to fix. The end face of the steel belt is trimmed, so that the subsequent welding of workers can be facilitated, and the quality of a welding seam can be improved. And (3) the worker abuts one side of the steel strip against the datum device, then the clamp is put down, the steel strip is fixed by the clamp, and then the worker starts to weld the joint of the steel strip. The steel strip is fixed by matching the clamp and the reference device, a worker can fix the steel strip without holding the steel strip by hands when welding operation is carried out, the labor intensity of the worker is reduced, the influence of human factors on the welding line is further reduced, and the quality of the welding line can be further improved.

The staff need start welding from the both ends of welding seam to the centre when welding the steel band, can reduce the steel band because of the deformation that welding high temperature produced like this in weldment work, reduce the influence of welded high temperature to the welding seam to further improve the quality of welding seam. After welding, cleaning up welding slag on the surface of the welding seam by workers, polishing two surfaces of the welding spot and the welding seam to enable the surface of the welding seam to be smooth, and then checking the thickness of the welding seam. Thereby ensuring the quality of the welding seam.

e. And (4) detecting, namely detecting the product after the rolling cutting processing, and then rolling up the qualified finished product.

When the staff inspects the finished product, the thickness, the surface and the width of the finished product need to be inspected, the staff sends the finished product with qualified quality to the winding equipment for winding, and sends the finished product with unqualified quality to a waste product position for waste treatment.

The staff is in the same place the short steel band welding of length, after guaranteeing the quality of welding seam, can splice the long steel band of length that can use with the short steel band of length that can not use, avoids the waste of steel band, has improved the utilization ratio of raw materials and staff's efficiency, reduction in production cost.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
