Description

How to make a non-slip pallet with a forming machine

The present invention relates to a method for producing a non-slip palette, and more particularly, to a method for manufacturing a non-slip palette having a non-slip palette of different left and right sides with a forming machine.

In general, the non-slip pallets used are different in shape from side to side, height from side to side, thickness is 3-5m / m, material is steel, and has a relatively complicated structure, which is widely used in parking towers and modern parking facilities. .

The method used for manufacturing this is a pressing method, which is bent by inserting a steel plate cut to a suitable length and width into a large press, which is inconvenient due to various complicated jig and peripherals, and it is not economical and the productivity per unit time is low. Since mass production was nearly impossible, these factors were the main reason for the high cost. In addition, the problem of lowering the added value was raised because of the poor precision of the product. Therefore, in order to develop a forming method that enables the product's strength and precision to be mass-produced per unit time, the industry has spared a lot of research and investment for many years. It is known that it is almost impossible to accurately manufacture a thick steel sheet with a different and especially a thickness of 3-5m / m by the forming method.

Accordingly, the object of the present invention is to provide a forming method that allows mass production of a product having good strength, precision, and general condition per unit time.

Another object of the present invention is to provide a method for manufacturing a non-slip palette using a conventional forming machine.

The present invention according to the first check to achieve the above object, the first forming roller and the lower forming roller is a first step of assembling a roller for manufacturing a non-slip pallet having a different shape and left and right height of the left and right, and the iron plate When entering into the first forming roller and completing at the last forming roller, the pressing force between the first and second roll forming rollers and the lower forming roller is twice as high as the product. Tightening the axial pressure control handle as much as possible and at the same time, the first upper shaft rotates to the idle, and the third process rotates the upper shaft of the portion where the bending angle of the iron plate reaches almost 45 to the idle; A fourth step of controlling the pressing force of the iron plate at the portion where the angle of the bending part of the iron plate starts to exceed 45 degrees and equally the highest at the right and left sides; The upper and lower forming rollers and the upper and lower forming rollers in front of and behind the forming rollers at the beginning of the two-stage bending starting point at the highest height with the bending angle exceeding 60 degrees and reaching the highest angle. A non-slip pallet consisting of a fifth step of spraying an appropriate amount of lubricating oil and a sixth step of turning the upper axis to idle from the end of the unevenness to the final part of the flat part between the high and the low part of the product, and the final step. We propose a method of manufacturing with a forming machine.

The forming machine used in the present invention uses a forming machine which is commonly used as shown in FIG. 1 and FIG. 2, and the iron plate used is a conventional color sheet (prefabricated building material) and has a thickness of 1 m. If less than / m, it is possible to smoothly produce products with different left and right heights and different shapes of left and right through the forming machine without applying a tricky technique as in the prior art, but the present invention is a thick one with a thickness of 3-5m / m It is almost impossible to produce with a technique applied to a conventional forming machine because it is used to manufacture non-slip pallets with different left and right heights and different left and right shapes. Therefore, the present invention solved the above-mentioned products that were produced only through the pressing method by the forming method.

Hereinafter, a method for manufacturing a non-slip pallet according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1, 2 and 4 to 17. And, in order to more easily explain the manufacturing method of the present invention will be described in detail for each process.

Example 1

[Step 1]

As shown in FIG. 2 and FIG. 4, in order to produce non-slip pallets having different heights and shapes, the steel plate a mounted on the uncoiler 8 is first plate-formed roller 7. Pass between the first upper roller (50) and the lower roller to enter between the roller (70).

That is, when the iron plate (a) enters between the first upper forming roller 50 and the lower forming roller 70 described above, the upper shaft 10 is rotated to idle without assembling gears. At this time, since the gap between the upper forming roller 50 and the lower forming roller 70 is smaller than the thickness of the iron plate, even when the upper shaft 10 is in the idle state, the steel plate a enters the lower shaft under pressure (friction force). There is no problem in operation because it enters the same state as the rotation speed of 30).

[Step 2]

As shown in FIG. 2 and FIG. 5, the iron plate a which has undergone the first process is introduced between the second upper forming roller 51 and the lower forming roller 71. In this case, the upper shaft 11 is forcedly rotated by the gear 90 and the gear 101 engaged with each other while being assembled to the upper shaft 11 and the lower shaft 31.

Here, the first forming rollers (50, 70) and the second forming rollers (51, 71) described above should be adjusted so that the iron plate pressing pressure of the left end is about twice higher than the iron pressing pressure of the right end. As shown in the figure, it is possible to adjust the axial pressure adjusting handle 9. The axial pressure control handle (9) is a known configuration that has a structure that allows the top and bottom of the frame to be adjusted up and down screwing the pusher is assembled between the shaft.

On the other hand, as described above, the reason why the pressing force of the iron plate on the left side should be higher than that of the left edge, as shown in FIG. 3, since the product configuration on the left side is higher than the right side and there are many bending parts, This is because the phenomenon in which the mold rollers 51 and 71 enter to the left side is caused.

Therefore, the above-mentioned phenomenon can be corrected only when the iron pressing pressure on the left side is at least two times or two times higher than the iron pressing pressure on the right end. Therefore, in the embodiment of the present invention, the iron plate pressing pressure on the right side was 0.2kg / cm ² and the iron plate pressing pressure on the left side was 0.4kg / cm ² and there was no defect in the process (left maximum pressure: 0.42kg / cm ² ), Of course, the above-mentioned iron plate pressing pressure may vary somewhat depending on the shape of the product. Importantly, the steel plate pressing pressure of which the height of the product configuration is higher than the other side and the bending part is higher than the iron plate pressing pressure applied to the opposite side is at least 2 Hundreds of experiments confirmed the conclusion that it should be about twice.

[Third process]

As shown in FIGS. 6 and 7, the iron plate which has undergone the first and second processes, preferably the iron plate (a), which begins to bend, has a third up / down forming roller (52, 72) and As it enters between the fourth up and down forming rollers 53 and 73, it bends about 30 degrees and 45 degrees. At this time, the pressing force applied to the left and right sides of the upper forming roller (52, 53) and the lower forming roller (72, 73) is the same, the first and second forming roller (50, 51, 70, 71) Pressure should be applied at least equal to the average value of the pressed plate pressure.

In addition, the fourth upper shaft 13 has to be rotated to the children it can be seen that the phenomenon that the iron plate (a) does not lean to one side.

[4th process]

As shown in FIG. 8, the iron plate (a) having the third fixing described above enters the fifth up and down forming rollers 54 and 74 and is bent at an angle of about 60 degrees. At this time, the pressing force applied to the above-described upper and lower forming rollers 54 and 74 is equal to the left and right sides and the maximum pressure is applied in the process, and the magnitude of the pressure is the first and second forming rollers 50 and 51. 70,71), it should be understood that the minimum pressure should be at least 2 times higher than the average value of the iron pressing pressure. The maximum pressure is applied to the first and second forming rollers (50, 51, 70, 71). It was not possible to exceed three times the mean value of the pressing pressure.

On the other hand, in the embodiment of the present invention, the bending angle of the iron plate (a) should be applied to the fifth upper and lower forming rollers (54, 74) to reach the 60 degrees, the maximum iron plate pressing pressure should be smooth after the subsequent bending process. Many experiments have confirmed the loss.

[5th process]

As shown in Fig. 9, the iron plate (a) having been subjected to the fourth step described above is formed at about 70 to 80 degrees while passing through the sixth up / down forming rollers 55 and 75.

[Step 6]

As shown in FIG. 10, the iron plate (a) having undergone the fifth process enters the seventh up / down forming rollers 56 and 76 to generate a two-stage bending start point “k” at the higher side. do.

[Seventh Step]

As shown in FIG. 11, the above-described two-stage bending portion is preferably passed through the eighth up / down forming rollers 57 and 77 after the iron plate a having undergone the sixth process described above. The part bent by the sixth process is bent at about 45 degrees.

At this time, the sixth, seventh and eighth forming rollers (55, 75) (56, 76) (57, 77) are evenly sprayed with an appropriate amount of lubricant. The occurrence of minute cracks on the surface is almost eliminated, and the scratch sound is greatly reduced and the phenomenon of being pulled to one side is eliminated.

On the other hand, it can be seen that the iron plate pressing pressure of the up and down forming rollers (57, 77) is about half the level than the fifth up and down forming rollers (54, 74) described above, in particular, It was more desirable for one up / down forming rollers 57 and 77 to be slightly reduced in pressure.

[Step 8]

As shown in FIG. 12, the iron plate (a) having undergone the seventh process described above enters the upper and lower forming rollers 58 and 78, and the two-stage bending portion that performs the seventh process is about. The bending is completed at about 70 to 80 degrees, and at the same time, irregularities are formed on the upper side in the center of the straight portion between the left and right bending portions.

[Ninth process]

As shown in FIGS. 13 to 16, the top and bottom forming rollers 59, 79, 60, 80, 61, 81, 62, which are the tenth, eleventh, twelfth and final lines The forming process is terminated while passing through 52) while forming the above-mentioned unevenness, preferably at least four unevennesses formed by the eighth process.

At this time, the last tenth axis (19, 20, 21, 22), that is, the four upper shafts should be rotated to the idle from the above tenth, otherwise the bending state of the uneven portion was found to be poor.

In addition, as shown in FIGS. 14 to 16, the pressing force of the iron plate of each of the forming rollers 60, 80, 61, 81, 62, 82 is gradually decreased while the left and right sides are the same, and the final heat In the third up and down forming rollers (62, 82) it can be seen that the minimum pressure should be applied in the process. Iron plate pressing pressure at this time was about 0.1kg / cm ² was appropriate.

As described above, the present invention relates to a method of manufacturing a non-slip pallet having a non-slip pallet of different left and right and different heights as a forming machine, which is more economical than the pressing method and can be mass-produced per unit time, and has a surface state and a bending angle. In addition, it is possible to obtain a much more precise product than the conventional one, such as the dimensions of the finished product, as well as to reduce the production cost, thereby increasing the internal and external competitiveness, and there are many useful effects.
