The adjustment principle of the compression spring machine, we know that the adjustment of the compression spring machine can be divided into two types: the compression spring machine and the universal machine. The adjustment methods and basic principles are also different. Today, we will talk about the adjustment principle of the compression spring machine.
Related preparation work before equipment adjustment. The adjustment principle of the compression spring machine, before starting to adjust the sample spring, you need to prepare a series of spring compression machine tools in advance: 1 set of flow plate wire plate, 1 set of power transmission line board, 2 curve gauges, 1 pair of wire feed wheel 1 mandrel (ie auxiliary core), 1 cutter, 1 spacer knife, etc. Among them, the front and rear power transmission plates, curve gauges, and wire feed wheels must be of suitable wire specifications and used in supporting facilities. A group of power transmission The wire plates all include matching power line bubble glass.
In the first step, the basic installation and adjustment of the compression spring machine tool.
1. Transmission line board group after installation. The adjustment principle of the pressure spring machine, after installing the power transmission line board, the rear transmission line bubble glass and the power transmission line board cover;
2. Install wire feed wheel. Release the pressure and pressure handles, install the wire feed reel separately, and clarify the position of the reel seat, then tighten the pressure handle; 3. Install the mandrel. That is, install the auxiliary core and adjust the appropriate aspect ratio for later use.
The second step is to install and adjust the flow plate of the compression spring machine.
The length of the flow plate and the inclination of the import are critical to the accuracy and reliability of the manufacturing. The adjustment principle of the compression spring machine, please refer to the following process to adjust:
1. Adjust the inclination and the appropriate length of the entrance of the transmission line board to match the wire feed wheel and the auxiliary core. The adjustment principle of the pressure spring machine, the adjustment of the inclination of the entrance of the transmission line board should make the distance between the top of the entrance and the upper and lower wire feed wheels as small as possible, and then avoid the situation of squeezing due to excessive gaps. The length of the transmission line board is not suitable for too short. During the adjustment process, the gap between the transmission line board and the auxiliary core must be paid attention to. In addition, pay attention to the level and vertical position of the lower wire feeder when adjusting the power line board;
2. Pay attention to the distance between the transmission line board and the auxiliary core. The adjustment principle of the compression spring machine should not be as close as possible to the auxiliary core as far as it does not affect the stroke arrangement of the cutter.
The third step is to install and adjust the curve rule of the compression spring machine.
1. The curve gauge is adjusted moderately according to different spring diameters and relative requirements; 2. Use the steel wire that meets the specifications and drill finely grinded gypsum line grooves to make the coil forming operation smoother.
Step 4: Install and adjust the cutter.
Install the cutting knife and adjust the sharp knife of the knife. Note that if the sharp knife is too sharp, the adjustment principle of the spring compression machine may reduce its service life.
The fifth step is to install and adjust the flow board wire plate outlet.
If the exit of the flow plate and the wire plate is unfairly rounded in many ways, the formed spring cannot meet the required regulations, and even the spring body cannot be sealed.
Step 6: Install and adjust the interval knife.
When installing the spacing knife, pay attention to the distance between the spacing knife and the flow plate wire plate, the adjustment principle of the compression spring machine, and adjust the appropriate angle of view to make the spacing knife close to the flow plate wire plate.
The seventh step is to adjust and refine the flow plate and wire plate imports. Generally speaking, the inlet of the new flow board contains many sharp edges. If it is not solved, it will hurt the cable, so people have to drill and polish the plaster on the cable to solve it. The specific steps are as follows: 1. Close the power transmission line board and the bubble glass with your fingers; 2. Take a section of cable and smear it with drilled plaster; 3. Finely grind the cable back and forth to the entrance of the power transmission board until the power transmission board No need to scratch the cable.
Step 8: Adjust and fix the power transmission line board.
After moderately repairing all the relevant tools, we can install and fix the tool by adjusting the principle of the compression spring machine: 1. Install the power line board and fix it firmly; 2. Confirm again that all the tools are properly installed Accurate.
In the ninth step, the position of the spacing knife is determined again.
The minimum part of the spacer knife must be determined again before starting the calibration of the spring sample (generally the minimum part of the spacer knife is about mm lower than the spring body).
Step 10: Adjust and fix the fixed curve gauge. Install the curve gauge seat and the position where the fixed curve gauge is fixed.
The eleventh step, installation and adjustment of auxiliary core.
In general, the main purpose of the auxiliary core is only to disconnect the cable forming, the adjustment principle of the compression spring machine, we can adjust the auxiliary core according to the nominal diameter of the spring body and the screw element. The machine has the effect of victory or defeat of the auxiliary core: 1. If it is disconnected at the minimum diameter (or the same diameter), the auxiliary core can maintain the origin without moving; 2. If it is disconnected at a non-minimum diameter, the auxiliary core will be disconnected Reach out, return to the original point after disconnection.
Step 12: Finalize the work.
Make sure that the following relevant work checks are all correct and accurate: 1. Determination of the winding wire forming orientation: The adjustment principle of the compression spring machine, whether the selection of the winding wire orientation is in the appropriate location; 2. Whether the equipment transmission system structure is obstructed: cut Whether the position of the knife, interval knife, wire feed wheel, auxiliary core, etc. will block the movement of the equipment, etc.
Step 13: Install spring cables.
1. Release the pressure pressure handle, the adjustment principle of the pressure spring machine, let the upper wire feeder extend; 2. The spring cable installed will pass over the power line board, wire feed wheel, flow board wire plate successively; 3. Card Tighten the reel.
In the final step, adjust and clarify the minimum diameter of the coil.
1. Move the two curve gauges back, the adjustment principle of the spring compression machine makes the curling space more convenient for the cable; 2. The cable is based on the groove of the curve gauge directly below; 3. Correctly guide the cable into the upper curve gauge The wire groove can now send a piece of wire to form the spring body; 4. Gradually reduce the diameter of the spring.
