Portable 2 in1 Line Boring and Overlay Welding (Digital display screen)110V

Portable boring machine is a kind of portable processing equipment developed mainly for on-site maintenance of engineering, energy, and chemical equipment. It is mainly used for processing small pipe inner holes and concentric spacing holes. It is widely used in excavators, cranes, loaders, and cranes. And other construction machinery. Combining the actual needs of on-site processing, our factory continuously improves the equipment structure. After continuous improvement and perfection, the newly developed XDT50 portable boring and welding machine is currently a high-end integrated welding hole, boring, and end surface processing multiple functional modes. The operation of the equipment and equipment only needs one person to complete. The equipment is based on the site from the design concept to the processing. The actual operation difficulty of the workers is greatly reduced, making the maintenance personnel more handy.

Main application scope: post-welding processing of revolving holes, hinge holes, and shaft pin holes on various construction machinery structures, or adding hole sleeves after reaming; excavators, loaders, presses, and cranes with the same core holes Repair and processing, the holes are arranged side by side, and the holes are positioned and processed at one time to ensure the coaxiality of the holes.

7. Boring of processing equipment that is difficult to move with conventional machine tools.

Note
1. The operator must receive safety education and operation training, and have certain mechanical processing experience.
2. You must wear work clothes and protective glasses before using the machine.
3. Before starting the machine, check whether the voltage of the connected power supply is consistent with the voltage requirement on the nameplate of the machine.
4. Before starting the machine, check whether the card loading system is locked.
5. When aligning the workpiece, turn it by hand (when the gear is in the neutral position) or turn on the lowest speed for alignment. High-speed alignment is not allowed.
6. When the machine is started, please do not approach the equipment with your hands or other sundries to avoid personal injury.
7. The wires should be kept away from high temperature, grease and sharp edges.
8. When there is a malfunction or abnormal sound, the power should be turned off through the remote control immediately, and then the machine should be inspected and repaired.
9. Don't let the machine run in an unattended state. Be sure to stop the machine and check whether the transmission system is in neutral. Turn off the power before leaving.
10. It is strictly forbidden to use this machine beyond or below the processing range indicated on the machine, and our company will not bear any responsibility for the consequences.
11. The machine cannot exceed the specified maximum cutting capacity to avoid damage to the equipment and personal accidents.
12. After the machine is running, it is strictly forbidden to change the feed direction directly.
13. After the work is completed, the oil stains and iron chips on the machine should be removed, and anti-rust oil should be sprayed on the knife arm and the main shaft.
Operation Process
1. Support installation
A. Positioning boring bar
Install the fixing seat at the position where the workpiece is allowed to be welded. First use the nylon positioning taper sleeve to push the boring bar into the hole to be processed, and clamp the positioning boring bar with the tool holder at both ends to ensure the concentricity of the two holes.
B. Sleeve the support into the boring bar, and weld the two supports on the workpiece at a suitable position.
C. Remove the positioning taper sleeves (make sure that the boring bar can rotate freely and slide axially).
2 Install the main part
A. Put the main body part into the support .
B. Lock the feed transmission connecting rod and the boring bar.
3 Connect power
A. The equipment requires a power supply voltage of 110V, and the plug of the electric box is connected to a 110V power supply.
4 Hole welding process
A. Replace the boring bar with a welding rod support rod, insert the welding rod, install the welding torch head, and ensure that the welding torch head is 10mm away from the edge of the hole;
B. Connect the back-end connection line of the welding rod with the main welding machine connector;
C. First start the feed motor, adjust the rotation speed, and finally click the red button on the control handle to start automatic hole welding.
5 Boring process
A. Remove the welding assembly and install the boring hole.
B. Choice of tool holder
The hole diameter is Φ55-100mm, and the tool is placed in the strip groove of the boring bar and fixed with a compression screw.
When the hole diameter is greater than 100mm, different tool holders are chosen according to the size of the hole diameter.
C. Tool installation. Fix the ground tool on the boring bar or the tool holder according to the size of the hole to be processed (the sharpening of the tool can refer to the angle of the boring tool).
D. When setting the tool, please select neutral, rotate the boring bar, and adjust the tool so that the tip of the tool rubs the surface of the workpiece (the tool must be installed firmly).
4.5 During trial cutting, please select a single-side plunge depth of 0.2～1.0mm for trial cutting.
4.6 When processing, please arrange the feed amount reasonably according to the size of the trial cutting, adjust the feed knob, and adjust it slowly from zero generally in the range of 0-10 on the knob when adjusting. It must not be too fast, otherwise it will cause damage due to too fast feed.
4.7 When machining, please select a reasonable tool and a reasonable tool angle (refer to the tool angle of the boring tool).
