Technical Field

[0001] The utility model relates to the field of equipment related to metal surface hardening, in particular to a cleaning and drying device for metal parts before surface hardening. Background Art

[0002] The so-called surface hardening method refers to a process in which the surface of a part is hardened by appropriate methods while the core of the part still has strong toughness. Through this treatment, the wear resistance and fatigue resistance of the part can be improved, and since the core of the part still has good toughness and strength, it has good resistance to impact loads.

[0003] Before traditional metal parts undergo surface hardening, they must be thoroughly cleaned and dried. First, the parts are placed in a cleaning tank, where they undergo high-pressure and low-pressure cleaning with detergents, followed by a final rinse with clean water. After cleaning, the parts enter the drying phase. Traditional drying equipment uses direct hot air to evaporate any remaining moisture on the surface. However, this type of equipment consumes a lot of electricity and takes a long time to remove surface water droplets during the static process, resulting in low efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide a pre-hardening cleaning and drying device for metal parts that can effectively remove a large number of water droplets on the surface of metal parts and pre-squeeze the moisture absorbed by the sponge roller to ensure that it maintains good absorption capacity, which can solve the problems raised in the above-mentioned background technology.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1 、 Figure 2 and Figure 3 The figure shows a device for cleaning and drying metal parts before surface hardening, comprising a box body 1, the top of the box body 1 being open, and a conveying structure 2 being installed inside, a water absorption structure 4 being installed on the conveying structure 2, the water absorption structure 4 comprising a sponge roller 405 and an extrusion plate 406, and several extrusion plates 406 being evenly arranged, both sides of the extrusion plates 406 being fixedly connected with a drainage box 404, the top of one side wall of the box body 1 being connected to a water collection bin 401, and the bottom of the other side wall being fixedly connected with several support rods 403, several evenly arranged sponge rollers 405 being installed on the top of the box body 1, and the sponge rollers 405 and the extrusion plates 406 being staggered.

[0019] It is worth noting that the box body 1 can be placed in the unloading area of ​​the metal cleaning machine. After cleaning, the metal parts are placed on the surface of the mesh conveyor belt 201 in sequence, and each metal part is placed between two squeezing plates 406. Before the metal parts reach the squeezing and wiping area of ​​the upper sponge roller 405, the squeezing plates 406 will collide and squeeze the sponge roller 405. This action prompts the sponge roller 405 to absorb water and drain it. The squeezed water flows into the drainage box 404 and is discharged from both sides of the mesh conveyor belt 201 to avoid backflow to the surface of the metal parts. This process can effectively remove a large amount of water droplets on the surface of the metal parts and pre-squeeze the water absorbed by the sponge roller 405 to ensure that it maintains a good absorption capacity, thereby ensuring the wiping effect and reducing the power consumption of the metal parts directly dried after cleaning; through multiple sponge wiping, a large amount of water droplets can be quickly removed, ensuring the efficiency of the drying process.

[0020] See also Figure 1 and 2A first cover plate 101 and a second cover plate 102 are placed on the top of the box body 1, and several embedded hot fans 3 are installed on the second cover plate 102. It is worth noting that after the sponge wipes and absorbs the surface moisture, the hot fan 3 is continuously turned on to quickly dry the surface.

[0021] See Figure 1 、 Figure 2 and Figure 3 A drain port is provided at the front end face of the bottom of the water collecting bin 401, and a sealing plug 402 is connected to the internal thread. It is worth noting that the water squeezed out will flow into the water collecting bin 401 for collection. The sealing plug 402 should be removed regularly to drain the internal water resources.

[0022] See Figure 1 、 Figure 2 and Figure 3 The conveying structure 2 includes a mesh conveyor belt 201, and two parallel rotating shafts 203 rotate inside the box body 1. The outer wall of the rotating shaft 203 is fixedly sleeved with a conveying roller 204. The two conveying rollers 204 are connected through the mesh conveyor belt 201. The bottom side wall of the extrusion plate 406 is fixedly connected to the surface of the mesh conveyor belt 201. The box body 1 is located at the front corner position. A motor 202 is installed. The output end of the motor 202 passes through the side of the box body 1, and the through end is fixedly connected to one end of the adjacent rotating shaft 203. The mesh conveyor belt 201 is used to facilitate the contact of hot air during transportation, thereby ensuring drying and transportation at the same time. The mesh conveyor belt 201 is made of iron mesh material. Long-term hot air blowing and the conveying process are prone to deformation. It is fixedly connected to the surface of the mesh conveyor belt 201 through the extrusion plate 406, forming a reinforcing rib on the surface of the mesh conveyor belt 201, reducing the deformation rate of the mesh conveyor belt 201, thereby ensuring the service life of the mesh conveyor belt 201.

[0023] See Figure 3 The side wall of the extrusion plate 406 away from the mesh conveyor belt 201 is chamfered. It is worth noting that during the collision between the sponge roller 405 and the extrusion plate 406, the chamfered design on the extrusion plate 406 makes the collision contact surface arc-shaped, thereby reducing the puncture damage to the sponge roller 405 caused by the sharp edge collision, ensuring the complete service life of the sponge roller 405.

[0024] See Figure 4The sponge roller 405 is provided with a mounting shaft 4051, and the box body 1 is provided with two symmetrically arranged pads 4052 at the position of the sponge roller 405. The pads 4052 are fixedly connected to the adjacent sides of the box body 1. The top of the pads 4052 is fixedly connected to the plug rod 4056, and the top of the plug rod 4056 is fixedly connected to the screw 4055. The top of the screw 4055 slides through the mounting shaft 4051. The top of the screw 4055 is provided with a compression spring 4054, and the top of the screw 4055 is also threaded with a nut 4053. It is worth noting that by rotating and unscrewing the two nuts 4053 and removing the compression spring 4054, the entire sponge roller 405 can be removed. By adopting this installation method, a damaged sponge roller 405 can be replaced in time, ensuring that the service life of the device is extended. After installation, the compression spring 4054 generates a buffering force when the sponge roller 405 contacts the extrusion plate 406 and metal parts, effectively reducing the instantaneous impact force on the sponge roller 405, thereby reducing the risk of damage and further improving its service life.

[0025] Working Principle: The box body 1 can be placed in the unloading area of ​​the metal cleaning machine. After cleaning, the metal parts are placed on the surface of the mesh conveyor belt 201 in sequence. Each metal part is placed between two extrusion plates 406. The motor 202 is turned on, and the mesh conveyor belt 201 conveys the placed metal parts. When the metal parts reach the extrusion and wiping area of ​​the upper sponge roller 405, the extrusion plates 406 collide and squeeze the sponge roller 405. This action causes the sponge roller 405 to absorb water and drain it. The squeezed water flows into the drainage box 404 and is discharged from both sides of the mesh conveyor belt 201 to prevent it from flowing back onto the surface of the metal parts. The squeezed water flows into the water collection bin 401 for collection. The sealing plug 402 can be removed periodically for drainage.
