Description

Technical Field

[0001] This application relates to the field of spring electroplating, and more particularly to a support for spring electroplating. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. It is made of elastic material and deforms under the action of external force, and returns to its original shape after the external force is removed. The current production process of springs is as follows: pretreatment, rolling, annealing, quenching, tempering, surface treatment, and inspection. Among them, surface treatment is usually carried out by electroplating. The electroplated layer on the surface of the spring can protect the surface of the spring from oxidation and corrosion.

[0003] Currently, Chinese utility model patent CN220265923U discloses an electroplating bracket, including a mounting frame. The inner side wall of the mounting frame has a sliding groove, and the front surface of the mounting frame has a disassembly hole communicating with the sliding groove. A connecting column is slidably connected in the sliding groove, and a suspension hook is installed on the connecting column. A mounting sleeve is slidably connected to the mounting frame. A limit groove is opened on the connecting column, and a limit rod is slidably connected to the mounting sleeve. A stop plate is installed on the limit rod, and a return spring sleeved on the outside of the limit rod is installed on the stop plate. A mounting plate is installed on the mounting sleeve. This electroplating bracket has the function of improving electroplating efficiency.

[0004] Since the mounting bracket is immersed in the electroplating bath in a vertical position, it also needs to enter the electroplating solution along with the spring. As the mounting bracket is exposed to the air for a long time, it will adhere to a large number of impurities, and the material of the mounting bracket itself may even peel off. Impurities or metal residues will enter the electrolytic cell during the electrolysis process, which can easily lead to a decrease in the purity and performance of the electrolyte. Utility Model Content

[0005] In order to reduce the amount of mounting bracket entering the electroplating solution and thus ensure the purity and performance of the electrolyte, this application provides a bracket for spring electroplating.

[0006] This application provides a bracket for spring electroplating, which adopts the following technical solution:

[0007] A bracket for spring electroplating includes a mounting frame, several crossbars, and a limiting member. The mounting frame is provided with several lifting lugs for hoisting. The crossbars are evenly distributed on the mounting frame and inserted into the mounting frame. The crossbars are provided with hooks for hooking springs. The limiting member is used to prevent the crossbars from detaching from the mounting frame.

[0008] By adopting the above technical solution, the hoisting equipment, such as the overhead crane, lifts the mounting frame through the lifting lugs, ensuring the mounting frame is horizontal. Workers adjust the number of crossbars according to the required number of springs to be electroplated. The crossbars are directly inserted into the mounting frame. Restricting components reduce the movement of the crossbars relative to the mounting frame. Once the springs to be electroplated are hooked onto the hooks, the workers move the mounting frame directly above the electroplating tank and adjust the height using the hoisting equipment until the springs are fully in contact with the electroplating solution. At this point, only part of the hooks are in contact with the electroplating solution, reducing the direct entry of the support frame into the electroplating solution and minimizing impurities adhering to the support frame from contaminating the electroplating solution and affecting the spring electroplating quality.

[0009] Optionally, the limiting component includes a limiting frame, several limiting blocks, a limiting screw, and a limiting nut. The limiting frame is slidably connected to the mounting frame. The limiting blocks are disposed on the limiting frame and are used to abut against the side of the crossbar away from the mounting frame. The limiting screw is disposed on the mounting frame and the limiting frame passes through the limiting screw. The limiting nut is used to be threadedly connected to the limiting screw.

[0010] By adopting the above technical solution, the limiting component is used to prevent the crossbar from detaching from the mounting frame. When the crossbar is inserted into the mounting frame, the operator can move the limiting frame, which drives the limiting block to move until the limiting block abuts against the end of the crossbar away from the mounting frame. The movement of the limiting frame is restricted by the limiting nut, so that the limiting block remains abutting against the crossbar.

[0011] Optionally, the limiting block is provided with a guide slope to facilitate guiding the limiting block to abut against the side of the crossbar away from the mounting frame.

[0012] By adopting the above technical solution, when the crossbar is fully inserted into the mounting bracket, the guide ramp can make the crossbar fully inserted into the mounting bracket, and the guide ramp also guides the limiting block to move to a position where the crossbar is away from the mounting bracket.

[0013] Optionally, the crossbar includes a rod body and several adapter blocks. The rod body is inserted into the mounting bracket. The rod body has several adapter slots along its length. The adapter blocks are used to engage with the adapter slots. The hooks are disposed on the adapter blocks.

[0014] By adopting the above technical solution, the number of adapter blocks can be adjusted according to the number of springs that need to be placed on the crossbar. Since the hooks will enter the electroplating solution, the hooks need to be replaced regularly. The hooks are set on the adapter blocks so that the bar can be used continuously.

[0015] Optionally, a rubber pad is provided in the adapter groove, and the rubber pad is used to abut against the adapter block.

[0016] By adopting the above technical solution, the rubber pad is a deformable material. The deformation of the rubber pad enables the interference fit between the crossbar and the mating block, thereby improving the installation strength of the crossbar and the mating block.

[0017] Optionally, the mounting bracket is provided with two levels, which are perpendicular to each other.

[0018] By adopting the above technical solution, the level makes it easier for staff to check the horizontal status of the mounting bracket, ensuring that all springs can enter the electroplating solution during electroplating.

[0019] Optionally, the mounting frame is also provided with four leveling components, which are located around the mounting frame. Each leveling component includes a leveling rod and several counterweights. The leveling rod is vertically mounted on the mounting frame, and the counterweights are mounted on the leveling rod.

[0020] By adopting the above technical solution, when the springs in the mounting frame are unevenly distributed, the level is in an uneven state, and it is also inconvenient to adjust the adapter block. The staff can achieve the balance of the mounting frame by placing different counterweights on the four leveling rods, so that all the springs on the mounting frame can enter the electroplating solution.

[0021] Optionally, the outer side wall of the mounting bracket is also provided with rollers for abutting against the side wall of the electroplating tank.

[0022] By adopting the above technical solution, the electroplating tank is used to hold the electroplating solution, and the mounting frame is used to install the hooks on the crossbar where the spring is placed. When the spring needs to be electroplated, the height of the mounting frame needs to be lowered until the mounting frame enters the electroplating tank. The suspended mounting frame is prone to scratching the electroplating tank, and the impurities that are scratched off will directly enter the electroplating tank. The rollers can reduce the scratching between the mounting frame and the electroplating tank, thus ensuring the purity of the electroplating tank.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The lifting lugs on the sides of the mounting bracket enable the mounting bracket to be placed horizontally, and the hooks on the crossbar enable the spring to be engaged, reducing the part of the mounting bracket that enters the electroplating solution, thereby ensuring the purity and performance of the electrolyte.

Two snap-fit ​​blocks 211 are provided on the rod body 21. The two snap-fit ​​blocks 211 are distributed along the length of the rod body 21. The mounting frame 1 has snap-fit ​​grooves 13 on the upper end surface of the two side frames along the width of the mounting frame 1. The snap-fit ​​grooves 13 are used to snap-fit ​​the snap-fit ​​blocks 211. The rod body 21 abuts against the upper end surface of the mounting frame 1. Several adapter grooves 212 are provided on the upper end surface of the rod body 21. The several adapter grooves 212 are evenly distributed along the length of the rod body 21. A rubber pad 213 is fixedly provided in the adapter groove 212. When the adapter block 22 snaps into the rubber pad 213, the rubber pad 213 is in a deformed state. The hook 23 is fixedly provided on the adapter block 22. The lowest point of the hook 23 is located below the mounting frame 1. The hook 23 is used to hook the spring.

[0032] Reference Figure 1 and Figure 2The limiting component 3 includes a limiting frame 31, several limiting blocks 32, a limiting screw 33, and a limiting nut 34. The limiting frame 31 is slidably connected to the mounting frame 1 along the length direction of the mounting frame 1. Several limiting blocks 32 correspond to several crossbars 2. The limiting blocks 32 are fixedly set on the limiting frame 31. A guide slope 35 is provided between the lower end face of the limiting block 32 and the side wall of the limiting block 32. The lower end face of the limiting block 32 is used to abut against the upper end face of the rod body 21.

The leveling rods 41 are vertically arranged, and the lower end face of the leveling rods 41 is fixedly set on the upper surface of the mounting frame 1. The mating blocks are used to pass through the leveling rods 41 to adjust the levelness of the mounting frame 1.

[0034] The implementation principle of a bracket for spring electroplating in this application embodiment is as follows: the operator adjusts the layout of the crossbar 2 according to the size of the spring to be electroplated, then adjusts the number of adapter blocks 22 according to the number of springs, and then hooks the spring to be electroplated onto the hook 23. Then the operator moves the limiting frame 31 so that the limiting nut 34 cooperates with the limiting screw 33, and the limiting block 32 limits the rod body 21 to detach from the mounting frame 1. Then the mounting frame 1 is lifted by the hoisting device and sent into the electroplating solution. The rollers 12 on the side wall of the mounting frame 1 are used to abut against the inner side wall of the electroplating tank to reduce the scratches on the mounting frame 1.
