What are the advantages of the four-column hydraulic press?

The four-column hydraulic machine is an oil pump that delivers hydraulic oil to the integrated cartridge valve block. The hydraulic oil is distributed to the upper chamber or the lower chamber of the cylinder through the respective one-way valve and the relief valve, and the cylinder is moved under the action of the high-pressure oil. A hydraulic press is a device that uses a liquid to transfer pressure.

1. Reduce quality and save materials. For typical parts such as automobile engine brackets and radiator brackets, hydroformed parts are 20% to 40% less than stamped parts, and 40% to 50% of weight can be reduced for hollow stepped shaft parts.
2. Reduce the number of parts and molds and reduce mold costs. Hydroformed parts usually require only one set of molds, while stampings mostly require multiple sets of molds. The number of hydroformed engine bracket parts has been reduced from 6 to 1, and the number of radiator bracket parts has been reduced from 17 to 10.
3. It can reduce the amount of welding for subsequent machining and assembly. Taking the radiator bracket as an example, the heat dissipation area is increased by 43%, the number of solder joints is reduced from 174 to 20. The number of steps is reduced from 13 to 6 and the productivity is increased by 66%.
4. Improve strength and stiffness, especially fatigue strength, such as hydroformed radiator brackets, which can increase stiffness by 39% in the vertical direction and 50% in the horizontal direction.

How can we improve the accuracy of the injection machine?

1. The frame type automobile beam hydraulic machine has a row of hydraulic cylinders mounted on the upper beam along the length thereof. Among the hydraulic cylinders, the piston cylinders are located on the most sides of the two ends, and the rest are plunger cylinders; the moving table is installed on the top of the base The moving workbench, the upper beam, the slider and the base are all welded structure of the steel plate; the column is arranged at four corners between the upper beam and the base, and the column is connected with the upper beam and the base to form an integral frame structure; Guides are provided at the four corners of the slider, and the four guides are in one-to-one correspondence with the four columns. This product greatly improves the accuracy of the hydraulic press. The precision can be improved from the II-III level of the traditional structure to the I-special level. At the same time, the speed and synchronization of the slider movement are effectively improved, and the gap of the slider is reduced by 10-20mm. Up to 1.5mm. The invention also greatly improves the production efficiency of the equipment and the quality of the product, and the production efficiency can be improved by 1-3 times and the energy saving is 20-50%.
   The innovative mechanism of the frame type hydraulic machine locking mechanism comprises: a pair of horizontally arranged guiding blocks fixed on the inner side wall of the column, the outer surfaces of the two guiding blocks are fixed by bolts, and the horizontal locking cylinder is mounted outside the pressing plate; A slide plate is provided between the blocks in sliding engagement with the guide block, and the slide plate is connected to the piston rod of the lock cylinder through the connecting plate. In use, a pair of locking mechanisms are arranged on the inner side of the two columns of the frame hydraulic machine, and are arranged diagonally; the locking cylinder is used to drive the sliding plate to extend, so that the sliding plate enters the lower part of the sliding block to limit the position, thereby protecting the sliding block The staff below. No need to install on the upper beam, easy to install, low cost, safe and reliable structure.
