Description

Technical Field

[0001] The invention belongs to the technical field of electrophoretic coating, in particular to a uniform electrophoretic coating device for stamping parts. Background Art

[0002] Stamping is a forming process in which a press and a die apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. At present, the working environment of some stamping parts is very harsh, and they are often hit by sand and gravel and corroded by dirt such as mud and water on the ground. In order to extend the service life of stamping parts, a method of electrophoretic coating of stamping parts has been developed. Electrophoretic coating is a coating method that uses an external electric field to make particles such as pigments and resins suspended in the electrophoretic liquid migrate in a directional manner and deposit on the substrate surface of one of the electrodes. Compared with the previous dipping and spraying, the surface performance of stamping parts after electrophoretic coating has been greatly improved;

[0003] However, the current electrophoretic coating process for stamped parts requires first ensuring that the stamped parts are pre-treated to ensure that their surfaces are clean and dust-free. However, when the stamped parts are transferred to the top of the electrophoretic coating tank, they will inevitably be exposed to natural air. If the air contains granular dust and powder, it is very likely to adhere to the stamped parts that have been cleaned. When such stamped parts are electrophoretically coated, it is very likely that their surfaces will be uneven. In addition, if the paint, resin, and additives in the electrophoretic coating are not fully stirred in advance, it may also cause uneven electrophoretic coating of the stamped parts.

[0010] Preferably, springs are respectively fixedly connected between the bottom ends of the two groups of T-shaped slide plates and the inner walls of the bottom ends of the two groups of T-shaped slide grooves.

[0011] Preferably, each of the four suction and stirring structures includes an elastic bellows fitting fixedly connected to the inner wall of the bottom end of the electrophoretic coating pool box, and the two ends of the elastic bellows fitting close to the bottom are respectively and fixedly connected with a suction pipe and a delivery pipe, and the pipe bodies of the suction pipe and the delivery pipe are fixedly connected with a one-way valve.

[0012] Preferably, the pipe body of the delivery pipe is specifically connected to one end of the electrophoretic coating pool box, and a U-shaped groove plate is fixedly connected to the outer wall of one end of the electrophoretic coating pool box and is connected to the other end of the delivery pipe, and a rectangular plug plate is tightly clamped on the outer wall of one end of the U-shaped groove plate.

At the same time, the filtering water wheel plate that passively rotates to filter the electrophoretic solution can also synchronously drive the stirring rod to rotate. The rotating stirring rod can stir the electrophoretic solution in the electrophoretic coating tank box, so that various substances in the solution are fully and continuously stirred, thereby avoiding uneven electrophoretic coating.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a uniform electrophoretic coating device for stamping parts, including an electrophoretic coating tank box 1, a stamping part 11 is arranged above the electrophoretic coating tank box 1, a conveying device is tightly clamped on the top of the stamping part 11, and a uniform coating part 2 is also arranged in the electrophoretic coating tank box 1, and the uniform coating part 2 includes a concave folded screen plate 21 which is slidably connected to the inner wall of the electrophoretic coating tank box 1, a support plate 22 is fixedly connected to the inner wall of one end of the electrophoretic coating tank box 1 near the top, and an electric cylinder 23 is fixedly connected to the outer wall of the top of the support plate 22, and the electric cylinder 23 is fixedly connected to the outer wall of the top of the support plate 22. A baffle 24 is fixedly connected to the bottom end of the cylinder 23, and the bottom outer wall of the baffle 24 can be intermittently fitted and connected to the top outer wall of the concave sieve plate 21. A rotating suction structure is provided on the baffle 24, which is used to clean the surface of the stamping part 11 again when it contacts the electrophoretic solution to avoid dust adhesion. Four suction and stirring structures are provided on the bottom end of the electrophoretic coating tank box 1, which are used to circulate and filter the electrophoretic solution while stirring the electrophoretic solution to prevent the solvent from being uneven on the surface of the stamping part 11.

[0031] The above scheme is adopted: after the stamping part 11 is transported to the top of the electrophoretic coating tank box 1 by the conveying equipment on the top of the stamping part 11, the stamping part 11 is then driven to move down into the electrophoretic coating tank box 1. When it moves down to a certain position, the conveying equipment will drive the stamping part 11 to pause for a period of time. During the time when the stamping part 11 is passively stopped, the electric cylinder 23 installed on the support plate 22 can be immediately started to drive the railing 24 to move downward.

[0032] The rotary suction structure includes a bent torsion rod 25, a section of the rod body of the bent torsion rod 25 near the bottom is specifically a threaded rod, and is specifically threadedly connected to the guardrail 24, a sleeve rod 231 is movably sleeved on the rod body of the bent torsion rod 25, one end of the sleeve rod 231 is fixedly connected to the inner wall of the other end of the electrophoretic coating tank box 1, and an annular groove disk 26 is jointly and fixedly connected to the inner wall of the other two ends of the electrophoretic coating tank box 1, and an annular groove 27 is opened in the inner wall of the top end of the annular groove disk 26, and the inner wall of the annular groove disk 26 and the annular groove Two circular clamping horizontal plates 28 are jointly provided between the inner walls of the annular groove disk 26 and the annular groove 27, respectively, and the two circular clamping horizontal plates 28 are fixedly connected and slidably clamped with the inner walls of the annular groove disk 26 and the annular groove 27. A bellows 29 is jointly threadedly connected between the two circular clamping horizontal plates 28, and one end of the bellows 29 is specifically threadedly penetrated with a circular clamping horizontal plate 28 that is slidably clamped on the annular groove disk 26 and the annular groove 27. A trachea groove plate 230 is also jointly and fixedly connected between the outer wall of one end of the bent torsion rod 25 near the top and a circular clamping horizontal plate 28.

[0033] The above scheme is adopted: the downward moving baffle plate 24 will drive the bent torsion rod 25 threadedly connected to it to rotate, and its rotation process will be limited by the sleeve rod 231, so that it will produce a fixed-point rotation, and the rotating bent torsion rod 25 will drive a circular clamp horizontal plate 28 to perform a limited and guided rotation and sliding in the annular groove plate 26 and the annular groove 27, thereby stretching to the bellows 29 fixedly limited by another circular clamp horizontal plate 28, so that a negative pressure suction force is generated inside it, and then the area around the stamping part 11 is sucked through the trachea groove plate 230, so that the surface of the stamping part 11 can be cleaned again through the operation of rotating and sucking to prevent impurities from adhering to its surface.

[0034] Two T-shaped slides 232 are fixedly connected to the outer walls at both ends of the concave folded screen plate 21, and two groups of T-shaped grooves 233 are provided in the inner walls at both ends of the electrophoretic coating pool box 1, which can be slidably engaged with the two groups of T-shaped slides 232 respectively, and springs 234 are respectively fixedly connected between the bottom ends of the two groups of T-shaped slides 232 and the inner walls at the bottom ends of the two groups of T-shaped grooves 233.

[0035] The above scheme is adopted: when the guardrail 24 passively and continuously moves downward and contacts the concave folded screen plate 21, it will drive the concave folded screen plate 21 to move downward. At this time, the stamping part 11 with no dust on the surface is driven downward again by the conveying equipment, so that it gradually moves downward and is immersed in the electrophoretic solution in the electrophoretic coating tank box 1 for electrophoretic coating. The downward movement of the concave folded screen plate 21 will be guided downward in the corresponding T-shaped slide groove 233 through the T-shaped slide plate 232 on the outer walls at both ends, and the corresponding spring 234 will be squeezed at the same time during the downward movement process, and the concave folded screen plate 21 can be subsequently driven to reset through the spring 234.

[0036] Each of the four suction and stirring structures includes an elastic bellows member 235 fixedly connected to the inner wall of the bottom end of the electrophoretic coating tank box 1, and the two ends of the elastic bellows member 235 near the bottom are respectively connected with a suction pipe 236 and a delivery pipe 237, and the pipe bodies of the suction pipe 236 and the delivery pipe 237 are fixedly connected with a one-way valve, and the pipe body of the delivery pipe 237 is also specifically connected to one end of the electrophoretic coating tank box 1 through a fixed connection, and the outer wall of one end of the electrophoretic coating tank box 1 is fixedly connected with a U-shaped groove plate 238 that is connected to the other end of the delivery pipe 237 through a fixed connection, and the U-shaped A rectangular plug plate 239 is tightly clamped on the outer wall of one end of the groove plate 238, and a stirring rod 240 is provided on the other end of the U-shaped groove plate 238. A filtering water wheel plate 241 is fixedly connected to one side of the stirring rod 240, and two sections of the stirring rod 240 are also fixedly connected to rubber plug plates 242. The two rubber plug plates 242 are T-shaped and I-shaped respectively. The outer wall of one end of the T-shaped rubber plug plate 242 is fitted and connected to one end of the filtering water wheel plate 241, and the outer wall of the rubber plug plate 242 is fitted and rotatably connected to the other end plate of the U-shaped groove plate 238.

[0037] The above scheme is adopted: when the concave folded screen plate 21 moves down to a certain position, it will squeeze the elastic bellows 235 so that the solution sucked in advance inside it is output through the delivery pipe 237. When the solution in the U-shaped groove plate 238 with impact force flows upward into the U-shaped groove plate 238, it will first drive the filter water wheel plate 241 to rotate. The filter water wheel plate 241 can filter the upward solution to remove the solid particles and impurities that may exist in the electrophoresis solution. At the same time, the filter water wheel that passively rotates to filter the electrophoresis solution The plate 241 can also synchronously drive the stirring rod 240 to rotate. The rotating stirring rod 240 can stir the electrophoretic solution in the electrophoretic coating tank box 1, so that various substances in the solution are fully and continuously stirred to avoid uneven electrophoretic coating. When the elastic bellows 235 is no longer squeezed, it will automatically reset, and then the electrophoretic solution will be sucked again through the suction tube 236. The one-way valves installed on the suction tube 236 and the delivery pipe 237 are used to allow the solution to flow in only one direction.

[0038] One point that needs to be added is that when the bellows 29 passively rotates one circle, the baffle 24 also separates from the bent torsion bar 25. At this time, while the baffle 24 continues to passively move downward, the conveying equipment will also move the stamping part 11 downward at the same time, and the downward movement distance will not exceed the top position of the threaded rod body of the bent torsion bar 25.

[0039] The working principle and use process of the present invention are as follows: after the stamping part 11 is conveyed to the top of the electrophoretic coating tank box 1 by the conveying equipment on the top of the stamping part 11, the stamping part 11 is then driven to move down into the electrophoretic coating tank box 1. When it moves down to a certain position, the conveying equipment will drive the stamping part 11 to pause for a period of time (the conveying equipment is a prior art, and the specific moving trajectory is also set and driven by the central control system in the prior art). When the stamping part 11 stops passively, the electric cylinder 23 installed on the support plate 22 can be immediately started to drive the guardrail 24 to move downward. The downward-moving guardrail 24 will drive the bent torsion bar 25 threadedly connected to it to rotate. The rotation process will be limited by the sleeve rod 231 to cause it to rotate at a fixed point. The rotating bent torsion bar 25 will drive a circular The horizontal clamping plate 28 performs limited and guided rotation and sliding in the annular groove plate 26 and the annular groove 27, thereby stretching to the bellows 29 fixed and limited by another circular horizontal clamping plate 28, so that a suction force of negative pressure is generated inside the bellows 29, and then the air pipe groove plate 230 is used to suck the area around the stamping part 11, so that the surface of the stamping part 11 can be cleaned again by the operation of rotating and sucking at the same time to prevent impurities from adhering to the surface. When entering the electrophoretic coating tank box 1 for electrophoretic coating, uneven events may occur on the surface. Later, when the torsion bar 25 is passively turned over, a plastic bag is manually put on the air pipe groove plate 230 to discharge the impurities and gas in the bellows 29. When the bellows 29 has been used for too long and needs to be replaced, it can be replaced by rotating the thread to take it out;

[0040] When the guardrail 24 passively moves downward and contacts the concave folded screen plate 21, it will drive the concave folded screen plate 21 to move downward. At this time, the stamping part 11 with no dust on the surface is driven downward again by the conveying equipment, so that it gradually moves downward and is immersed in the electrophoretic solution in the electrophoretic coating tank box 1 for electrophoretic coating. The downward movement of the concave folded screen plate 21 will be guided downward in the corresponding T-shaped slide groove 233 through the T-shaped slide plate 232 on the outer walls at both ends. The downward movement process will squeeze the corresponding spring 234 at the same time, and the spring 234 can subsequently drive the concave folded screen plate 21 to reset. When the concave folded screen plate 21 moves down to a certain position, it will squeeze the elastic bellows 235 so that the solution sucked in advance inside it is output through the delivery pipe 237, and the solution in the U-shaped slot plate 238 with impact force is input. When entering the U-shaped groove plate 238 and generating an upward flow, it will first drive the filter water wheel plate 241 to rotate. The filter water wheel plate 241 can filter the upwardly moving solution to remove solid particles and impurities that may exist in the electrophoretic solution. At the same time, the filter water wheel plate 241 that passively rotates to filter the electrophoretic solution can also synchronously drive the stirring rod 240 to rotate. The rotating stirring rod 240 can stir the electrophoretic solution in the electrophoretic coating tank box 1, so that various substances in the solution are fully and continuously stirred, thereby avoiding uneven electrophoretic coating of the stamping part 11. In this way, the electrophoretic solution is filtered and stirred during the circulation process, and the impurities filtered on the surface of the filter water wheel plate 241 can be cleaned by removing the rectangular plug plate 239 on the U-shaped groove plate 238.
