Making an eccentric gear press

2021-06-29

What do I need to make an eccentricgear, press? Many people have seen the function of the eccentric gear press and the convenience brought about by human life, and they are curious about how much it costs to make an eccentric gear press. There are also some people who have a need for presses, but the things they want to process are relatively simple and small-volume. The cost of buying an eccentric gear press is too high, and the stamping factory is not willing to process it. At this time, you can do an eccentric gear press yourself.


Point:
      1. Principles and materials
      2. Production process
      3. Conclusion


1. Principles and materials
To make an eccentric gear press, first confirm the working principle, push the pressure beam down by the jack, and punch the workpiece placed on the pressure plate
The materials to be prepared include channel steel, angle steel, steel plate, jack, gear, spring, ring gear 1, support ring 2, balance body 3, center shaft cylinder 4, and eccentric body 5 respectively disposed at the lower ends of the center shaft cylinder 4, etc. Tools that need to be prepared include cutting machines, electric welders, punchers, and the like.


2. Production process
1) Determine the size, use the cutting machine to cut the channel steel to make the columnbeam, upper beam and pressure beam. And use the puncher to punch holes in the column. The purpose of punching is to adiust the stroke. The holes on the columns on both sides must be on a horizontal line, otherwise the beam will be inclined. Steel is the unit of force, must choose the national standard steel, the size of the specific material can refer to the manual press size chart
2) Use the cut material, the installation drawings are welded or fixed with screws. It should be noted here that eccentric gear press beam is moving up and down. The bottom angle iron must be firm. During the manual press operation, the machine needs to withstand a pressure of ten or even tens of tons. Therefore, it is very important that the machine is welded firmly. The welding cannot be welded, and it must be fully welded.
3) The outer circle of the support ring 2 is welded and fixed in the inner hole of the ringgear, and the inner hole of the support ring 2 is set in the middle of the middle shaft cylinder 4, and is welded to the middle portion of the middle shaf cylinder 4. The balance body 3 is used for balancing the eccentric gear, so that the center of gravity of the eccentric gear is maintained at the center of the center shaft cylinder 4, and the balance body 3 is disposed at the upper middle portion of the center shaft cylinder 4, on the left side of the hub of the support ring 2, and the outer circumference of the center shaft cylinder 4, respectively. Solder joint with support ring 2. The balance body 3 has a fan shape and is welded by two laminated balance sheets 31. The eccentric body 5 includes a connecting rod inner ring 51, a circular lining plate 52, a front inner struts 53 and a rear inner struts 54. The circular lining plate 52 is welded to the middle of the connecting rod inner ring 51 and is welded to the inner shaft cylinder 4 Two.front inner struts 53 and two rear inner struts 54 are symmetrically inclined on both sides of the circular lining plate 53 between the circular lining plate 53 ano the support ring 2, and respectively respectively with the circular lining plate 53 and the middle shaft cylinder 4 The lower outer circle and the support ring 2 are welded and fixed, and the eccentric distance a between the center of the connecting rod inner ring 51 and the center of the central shaft tube 4 is between 290 mm and 310 mm, and the two sides of the circular lining plate 53 are symmetrically welded and four shortly reinforced. The ribs 55 and the six long riby 56 are usedo strengthen the eccentric gear strength, and the front inner struts 53 and the rear inner struts 54 are welded to the corresponding long ribs 55
 4) Install jacks, gears, and springs. lacks should choose a brand with excellent quality andthe spring force must be sufficient. If you feel that the jack is inconvenient to use, you can replace the jack with a manual hydraulic pump and a hydraulic cylinder. The principle and manufacturing process are the same, except that the manual hydraulic pump is fixed to the side of the column.


3. ConclusionThe above is the whole process of making an eccentric gear press. Learning to make an eccentric gear press can fully understand the working principle of this press, even if it is not made, it will help you to use it more.
