Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve block processing technology, and more specifically, to a surface phosphating device for hydraulic valve block processing. Background Technology

[0002] Hydraulic valve blocks are important components used to regulate and control fluid pressure and flow in hydraulic systems. During processing, hydraulic valve blocks require phosphating, a common pretreatment technique. The purpose of phosphating is primarily to protect the hydraulic valve block, preventing corrosion to a certain extent; it also serves as a primer before painting, improving the adhesion and corrosion resistance of the paint film.

[0003] The existing method of phosphating hydraulic valve blocks involves immersing them all in a phosphating tank, and then removing them one by one after phosphating. This method is inefficient and the removal process is very inconvenient. In addition, during the traditional phosphating process, the hydraulic valve blocks piled up in the phosphating tank are in contact with the static phosphating solution, which prevents the hydraulic valve blocks from fully contacting the phosphating solution and thus reduces the surface treatment effect of the hydraulic valve blocks. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a surface phosphating device for processing hydraulic valve blocks.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A surface phosphating device for processing hydraulic valve blocks includes a processing box with two partitions dividing the box into two heating chambers and a storage chamber. A heating plate is installed in each heating chamber and electrically connected to a temperature sensor located in the storage chamber to detect the temperature of the phosphating solution, ensuring the solution is maintained at a suitable temperature for phosphating the hydraulic valve blocks. An ultrasonic generator is also installed in the storage chamber to generate high-intensity pressure waves during the phosphating process, thereby improving the overall phosphating effect. A lifting mechanism is mounted on the processing box, detachably connected via a lifting device to a storage grid box for holding the hydraulic valve blocks. Operation of the lifting mechanism allows the storage grid box to enter or leave the storage chamber.

[0007] Furthermore, the top of the heating chamber is provided with a cover plate to seal the heating chamber and prevent heat loss from the heating chamber.

[0008] Furthermore, the lifting mechanism includes a mounting frame, a lifting cylinder, a guide rail, and a mounting plate; the mounting frame is vertically installed outside the processing box, and the lifting cylinder and guide rail are vertically installed on the mounting frame. The telescopic end of the lifting cylinder is connected to the mounting plate which is slidably installed on the guide rail so that the lifting cylinder operates to make the mounting plate move up or down. The mounting plate is equipped with a lifting device.

[0009] Furthermore, the lifting device includes hooks and lifting lugs; there are two hooks and they are mounted on the mounting plate, and the hooks are connected to two lifting lugs mounted on the storage grid box.

[0010] Furthermore, the processing tank is equipped with a drain pipe and a filtration and return mechanism. The drain pipe is located at the bottom of the processing tank and is connected to the storage chamber at one end and to the filtration and return mechanism at the other end. This allows the filtration and return mechanism to operate so that the phosphating liquid in the storage chamber is filtered and then discharged back into the storage chamber, thereby improving the utilization rate of the phosphating liquid.

[0011] Furthermore, the filtration return mechanism includes a liquid pump, an inlet pipe, an outlet pipe, a filter box, a filter screen, and a guide pipe; the liquid pump is installed on the processing box and is connected to the inlet pipe and the outlet pipe, the inlet pipe is connected to the filter box, the filter box is equipped with a filter screen, and the filter box is connected to the drain pipe through the guide pipe, while the outlet pipe is connected to the storage chamber.

[0012] Furthermore, the filter box is equipped with at least two layers of filter screens with different pore sizes to improve the filtration effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model improves the phosphating efficiency of hydraulic valve blocks by adopting a batch loading and unloading method. The hydraulic valve blocks are placed in a storage grid box, and the storage grid box is driven into the liquid storage chamber for phosphating or removed from the liquid storage chamber for unloading. Since the storage grid box and the lifting mechanism are connected by a lifting device, the storage grid box and the lifting mechanism are detachable. After the lifting mechanism lifts the storage grid box, the lifting device is released to remove the storage grid box. Then, the storage grid box containing the new batch of hydraulic valve blocks is fixed on the lifting mechanism to complete a new round of phosphating. During the phosphating process, the operation of the ultrasonic generator causes the phosphating liquid to form a high-intensity pressure wave on the hydraulic valve blocks, thereby improving the comprehensiveness of the phosphating of the hydraulic valve blocks and having better application value.

[0015] 2. This utility model improves the utilization rate of phosphating solution by setting up a drain pipe and a filter return mechanism, and avoids excessive impurities in the storage chamber from affecting the normal phosphating operation of the hydraulic valve block.
