Problems solved by technology

[0003] The present invention aims at the fact that the steel plate in the prior art is affected by forming restraint in the process of pressing, and it is easy to produce tensile defects, and the traditional press needs to be equipped with two or more hydraulic equipment, and the power configuration of the press is high. , leading to high cost of equipment, serious loss of mold, high power consumption of steel plate pressing, high production cost and other disadvantages. It provides a method of distributed pressing using the first pressing mold and the second pressing mold, which solves the defects of steel plate forming pinning and stretching. The power configuration of the press is reduced, the die loss is reduced, and the product quality is superior. It is suitable for the special steel structure industry, especially for the integral press split molding equipment and process for forming corrugated steel plates and special-shaped steel plates.

Embodiment 1

[0031] Integral press split molding equipment, such as Figure 1 to Figure 6 Shown, comprise press platform 1, first press mold 2, back press mold 3 and lower mold 5, described back press mold 3 is connected with press platform 1, first press mold 2 is equipped with adjustable elastic force device 4, can Adjusting elastic force device 4 is connected with press platform 1.

[0032] First press mold 2 and back press mold 3 are split type, and back press mold 3 comprises left back press mold 31 and right back press mold 32, and first press mold 2 is arranged between left back press mold 31 and right back press mold 32. The pre-pressing die 2 and the post-pressing die 3 are separated at the straight line between the crest and the trough of the corrugated steel plate, which can effectively avoid tensile defects at the corners.

[0033] The adjustable elastic device 4 is an adjustable hydraulic oil cylinder. An overpressure relief valve is installed on the adjustable hydraulic cyl...

Embodiment 2

[0044] Integral press split molding equipment, such as Figure 1 to Figure 6 Shown, comprise press platform 1, first press mold 2, back press mold 3 and lower mold 5, described back press mold 3 is connected with press platform 1, first press mold 2 is equipped with adjustable elastic force device 4, can Adjusting elastic force device 4 is connected with press platform 1.

[0045] First press mold 2 and back press mold 3 are split type, and back press mold 3 comprises left back press mold 31 and right back press mold 32, and first press mold 2 is arranged between left back press mold 31 and right back press mold 32.

[0046] The adjustable elastic device 4 is a telescopic rod adjusting device, which includes a telescopic rod 41 and a telescopic rod locking device 42 . There are four adjustable elastic devices 4, which are evenly distributed between the press platform 1 and the first pressing mold 2.

[0047] The integral press split molding process includes the following steps...

Embodiment 3

[0057] The difference between this embodiment and Embodiment 1 is that the adjustable elastic device 4 is an adjustable hydraulic cylinder, and the flat steel plate 8 is put into the lower mold 5, and the first pressing mold 2 is pressed down by controlling the adjustable hydraulic cylinder, and the valley steel plate is pressed down. Press into the mold cavity of lower mold 5. At this time, the rear mold has not been pressed down yet, because the two sides are free and unrestricted, so the lower pressure of the first mold is lower; then the press platform 1 drives the rear mold 3 to press down as a whole, and the The steel plate 8 is pressed into a corrugated form, and this process is repeated to press the continuous corrugated steel plate 9.

[0058] In the above process, during the pressing down process of the first pressing mold 2, until the pressing down of the first pressing mold 2 is completed, the oil pressure of the adjustable hydraulic cylinder rises to the set value,...

Abstract

The invention relates to mould pressing equipment and process, and discloses overall pressing machine split mould pressing equipment and process. The overall pressing machine split mould pressing equipment comprises a pressing machine platform (1), a first pressing mould (2), a second pressing mould (3) and a lower mould (5). The second pressing mould (3) is connected with the pressing machine platform (1), and an adjustable elastic device (4) is arranged on the first pressing mould (2) and is connected with the pressing machine platform (1). The process comprises the steps that the first pressing module presses downwards at first, and then the second pressing mould presses downwards; the second pressing mould is lifted, and then the first pressing mould is lifted. According to the overall pressing machine split mould pressing equipment and process, due to the fact that the first pressing mould and the second pressing mould are distributed to press, the defects of restrained stretching during steel plate forming are overcome, the power configuration of the pressing machine is reduced, mould loss is reduced, and product quality is good; the overall pressing machine split mould pressing equipment and process are suitable for special steel structure industries, and particularly suitable for forming of corrugated steel plates and special-shaped steel plates.

Description

technical field [0001] The present invention relates to molding equipment and technology, in particular to an integral press split molding equipment and technology. Background technique [0002] At present, when corrugated steel plates and other special-shaped parts are molded, the depression of the wave trough steel plate is restrained by the wave crest steel plate, which causes the steel plate to be artificially stretched and causes defects such as cracks. Therefore, the traditional one-time forming method cannot meet the requirements, but there are many wave specifications. It is impossible to make many split presses according to various waveforms, so it is particularly important and urgent to realize the research of split molding on the basis of the whole press. Contents of the invention [0003] The present invention aims at the fact that the steel plate in the prior art is affected by forming restraint in the process of pressing, and it is easy to produce tensile def...
