Description

Technical Field

[0001] The present application relates to the field of metal part processing equipment, and particularly to a blanking mechanism for metal workpieces on a hanger. Background Art

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic field to make negatively charged paint particles move in a direction opposite to the electric field and adsorb the paint particles on the surface of the workpiece. The electrostatic spraying equipment consists of a spray gun, a spray cup, and an electrostatic spraying high-voltage power supply, etc. During operation, for the spray gun or spray disc and spray cup of the electrostatic spraying, part of the paint particles are connected to the negative electrode, the workpiece is connected to the positive electrode and grounded. Under the action of the high voltage of the high-voltage power supply, an electrostatic field is formed between the end of the spray gun (or spray disc, spray cup) and the workpiece. The electric field force received by the paint particles is proportional to the voltage of the electrostatic field and the charge amount of the paint particles.

[0003] In the related art, powder electrostatic spray guns are generally arranged on both sides of the spraying line. Metal structure products are hung on metal racks and move through between the spray guns on both sides. The powder electrostatic spray guns move up and down to perform powder electrostatic spraying on the metal structure products. After spraying, heat baking and cooling are carried out to melt the powder on the metal surface to form a protective film, and then painting and drying are carried out.

[0004] During processing, the hanger is driven to move by the moving rack of the production line. Several metal parts are hung on the hanger. The hanger includes a main rod and several hanging rods distributed on the side wall of the main rod. Hanging holes are provided on the metal workpiece, and the metal workpiece is hung on the end of the hanging rod far from the main rod.

[0005] Currently, the blanking of metal workpieces from the hanger is carried out manually, with a relatively high labor cost and slow work efficiency. Summary of the Invention

[0006] In order to reduce labor costs and improve work efficiency, the present application provides a blanking mechanism for metal workpieces on a hanger.

[0007] A blanking mechanism for metal workpieces on a hanger provided by the present application adopts the following technical solution:

[0008] The blanking mechanism for metal workpieces on a hanger includes a hanger body and a blanking mechanism main body. The hanger body includes a main rod and several hanging rods on both sides of the main rod. The length direction of the hanging rod is horizontal, and the hanging rods are symmetrically fixed on the horizontal sides of the main rod. The hanging rods on the same side of the main rod are arranged vertically; the top of the main rod is movably connected with an installation rod, and the top of the installation rod is used to connect the moving rack of the production line; a stable ring is coaxially fixed at the top of the main rod, and a stable surface is provided on one horizontal side of the stable ring, and the stable surface is a vertical surface;

[0009] The main body of the blanking mechanism includes a positioning belt and two groups of blanking components. When the stable ring moves to one side of the positioning belt, the distance between the side wall of the positioning belt and the center of the stable ring is less than the radius of the stable ring, and the positioning belt fits the stable surface. At this time, the hanging rods are located on both sides of the moving direction of the main rod.

[0010] The two groups of blanking components are located on both sides of the moving direction of the main rod, and the blanking components blank the workpieces on both sides of the main rod.

[0011] By adopting the above technical solution, the hanger body moves along the assembly line. When it moves to the blanking area, the stable ring begins to abut against the positioning belt. If the arc surface of the stable ring abuts against the side wall of the stable belt, the stable ring rotates until the stable ring rotates to abut against the stable surface. At this time, the stable surface and the positioning belt are in low-contact sliding, so that the positioning belt keeps abutting against the stable surface to achieve positioning. At this time, the hanging rods are located on both sides of the moving direction of the main rod, and the blanking components blank the workpieces on the hanging rods on both sides of the main rod, realizing automatic blanking and making the blanking convenient.

[0012] Optionally, the mounting rod and the main rod are movably connected by a connecting structure. The connecting structure includes a connecting ball and a connecting ring. The connecting ring is coaxially connected to the bottom end of the mounting rod, the connecting ball is coaxially fixed to the top end of the main rod, and the inner diameter of the connecting ring is larger than the outer diameter of the main rod and smaller than the outer diameter of the connecting ball.

[0013] By adopting the above technical solution, the connecting ball cannot pass through the connecting ring, but the connecting ball can swing, which is convenient for the workpiece to rotate when it is hung on the hanging rod. And when the arc surface of the stable ring abuts against the positioning belt, the main rod remains vertical, so that the workpiece will not fall off.

[0014] Optionally, a friction-reducing layer is provided on the stable surface.

[0015] By adopting the above technical solution, it is convenient for the stable surface to slide on the positioning belt and reduce wear.

[0016] Optionally, the blanking component includes a base, a support column slidably arranged on the base, and two groups of toggle seats slidably arranged on the support column and moving away from or approaching each other; a toggle arm is arranged on the toggle seat, the toggle arm extends in the direction of approaching each other on the toggle seat, and a gap for accommodating the workpiece is arranged between the toggle arm and the support column.

[0017] By adopting the above technical solution, during blanking, the positioning belt positions the workpiece. After the support column slides close to the assembly line, the workpieces on the same side of the main rod are located between the two toggle seats. After the toggle seats slide close to each other, the toggle arm is located on the side of the workpiece far from the support column, that is, the workpiece is located in the gap between the toggle arm and the support column; then the support column slides away from the workpiece, so that the workpiece is separated from the hanging rod, thus completing the blanking and making the blanking of the workpiece convenient.

[0018] Optionally, the support column includes a vertical beam and a horizontal beam, the end of the horizontal beam is arranged on the side wall of the vertical beam, and the two groups of the toggle seats are slidably connected to the horizontal beam.

[0019] By adopting the above technical solution, the end of the crossbeam is fixed to the vertical beam, so that the space below the crossbeam is empty, and a container for storing workpieces is conveniently arranged under the crossbeam.

[0020] Optionally, a guard plate is provided at the bottom of the toggle arm, and an inclined plate is provided at the bottom of the guard plate, and the inclined plates at the bottom of the two toggle arms are close to each other and extend downward.

[0021] By adopting the above technical solution, the inclined plate and the guard plate are set, so that the workpiece is first stored between the two guard plates and the two inclined plates, and then when it is moved to the position farthest from the main rod, the two toggle seats move away from each other, and the workpiece falls into the container where the workpiece is placed, so that the workpiece will not fall during the movement, and the inclined plate has a guiding function, so that the workpiece can slide easily.

[0022] Optionally, a buffer plate is provided on one side of the middle of the two guard plates close to each other, and the buffer plate extends downwardly in an inclined direction toward each other. When the two inclined plates are located at the closest position to each other, there is a gap for falling objects between the two buffer plates.

[0023] By adopting the above technical solution, since several workpieces on the main rod are arranged vertically and hung on the hanging rod, if the workpiece near the top of the main rod falls directly on the inclined plate, the impact force is large, which is easy to cause damage to the workpiece surface, thus affecting the product appearance. By setting a buffer plate, the high-position workpiece falls on the buffer plate first. Since there is a gap between the two buffer plates when the two inclined plates are at the closest position to each other, when the two guard plates are separated to half, the workpiece on the buffer plate falls on the lower inclined plate again. After the guard plates continue to separate, all the workpieces on the inclined plate fall again, so that the high-position workpiece falls in steps, reducing the impact force of the fall and reducing the damage to the workpiece appearance.

[0024] Optionally, buffer pads are provided on the top surfaces of the inclined plate and the buffer plate.

[0025] By adopting the above technical solution, the appearance of the workpiece can be protected and wear can be reduced.

[0026] Optionally, a material collection basket is also included. When the support column slides away from the hanger body, the material collection basket is located below the two toggle seats.

[0027] By adopting the above technical solution, the workpiece falls into the aggregate basket after unloading, which is convenient for subsequent transportation. In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the arc surface of the stable ring abuts against the side wall of the stable belt, the stable ring rotates until it rotates to abut against the stable surface. At this time, the stable surface and the positioning belt have a sliding low contact, so that the positioning belt keeps abutting against the stable surface to achieve positioning. The hanging rods are located on both sides of the moving direction of the main rod. The blanking assembly blanks the workpieces on the hanging rods on both sides of the main rod, realizing automatic blanking, making the blanking convenient and saving labor costs;

[0029] 2. The settings of the connecting ring and the connecting ball facilitate the rotation of the workpiece when it is hung on the hanging rod, and also keep the main rod vertical when the arc surface of the stable ring abuts against the positioning belt, so that the workpiece will not fall off;

[0030] 3. The setting of the buffer plate makes the workpieces at a high position fall in a stepped manner, reducing the impact force received and making the surface of the workpiece not easily damaged. Description of the Drawings

[0035] The following further describes the present application in detail with reference to the drawings.

[0036] The embodiment of the present application discloses a blanking mechanism for metal workpieces on a hanger. Referring to Figure 1 , the blanking mechanism for metal workpieces on the hanger includes a hanger body 1 and a blanking mechanism main body. After several workpieces 7 are hung on the hanger body 1, processes such as powder spraying, heating, painting, and drying are carried out in sequence, and then the blanking structure main body blanks the processed workpieces 7 from the hanger body 1.

[0037] Referring to Figure 1, the hanger body 1 includes a main rod 11 and a number of hanging rods 12 on both sides of the main rod 11. In the embodiment, four hanging rods 12 are arranged on each side of the main rod 11. The length direction of the hanging rod 12 is horizontal, and the hanging rods 12 are symmetrically fixed on the horizontal sides of the main rod 11, and the hanging rods 12 on the same side of the main rod 11 are arranged vertically. The top of the main rod 11 is movably connected with an installation rod 13, and a hook 131 is integrally formed at the top of the installation rod 13. The hook 131 is used to hook and connect the moving frame of the production line, so that the hanger body 1 moves along with the production line.

[0038] Refer to Figure 1 , Figure 2 , the installation rod 13 and the main rod 11 are movably connected by a connection structure 2. The connection structure 2 includes a connection ball 21 and a connection ring 22. A connecting plate is coaxially fixed at the bottom of the installation rod 13, and a number of support rods 23 are fixed on the connecting plate. The bottom ends of the support rods 23 are fixedly connected to the outer wall of the circumference of the connection ring 22, so that the connection ring 22 is coaxially movably connected to the bottom end of the installation rod 13. The connection ball 21 is coaxially fixed to the top of the main rod 11, the connection ball 21 is located above the connection ring 22, the top of the main rod 11 passes through the connection ring 22, the inner diameter of the connection ring 22 is larger than the outer diameter of the main rod 11 and smaller than the outer diameter of the connection ball 21. The top of the main rod 11 can swing within the connection ring 22.

[0039] Refer to Figure 3 , a stable ring 3 is coaxially fixed to the top of the main rod 11, and a stable surface 31 is provided on one horizontal side of the stable ring 3. The stable surface 31 is a vertical surface.

[0040] Refer to Figure 1 , the main body of the blanking mechanism includes a positioning belt 5 and two groups of blanking components 4. The positioning component positions the workpiece 7 on both sides of the moving direction of the main rod 11, and the blanking components 4 blank the workpieces 7 on both sides of the main rod 11 respectively.

[0041] Refer to Figure 1 , Figure 3 , the horizontal height of the positioning belt 5 is the same as that of the stable ring 3, and the side wall of the positioning belt 5 is vertical. When the stable ring 3 moves to one side of the positioning belt 5, the distance between the side wall of the positioning belt 5 and the center of the stable ring 3 is less than the radius of the stable ring 3, and the positioning belt 5 fits the stable surface 31. At this time, the hanging rods 12 are on both sides of the moving direction of the main rod 11. When the arc surface of the stable ring 3 contacts the positioning belt 5, the stable ring rolls. A friction reducing layer is provided on the stable surface 31. The friction reducing layer is a coating layer to reduce the friction between the stable surface 31 and the side wall of the positioning belt 5. When the stable surface 31 contacts the positioning belt 5, the stable surface 31 and the positioning belt 5 slide stably.

[0042] Refer to Figure 1, Two groups of blanking components 4 are symmetrically arranged on both sides of the moving direction of the main rod 11. Each group of blanking components 4 includes a base 41, a support column 42 slidably arranged on the base 41, and the support column 42 slides away from or close to the workpiece 7 after sliding. A driving component 8 for driving the support column 42 to slide on the base 41, and the driving component 8 includes a driving motor 81, a driving slide rail 82 and a driving lead screw 83. The support column 42 includes a cross beam 421 and a vertical beam 422, and the bottom end of the vertical beam 422 is slidably connected to the base 41 through the driving slide rail 82. The two ends of the driving lead screw 83 are rotatably connected to the base 41, the middle part of the driving lead screw 83 is threadedly connected to the bottom of the vertical beam 422, the driving motor 81 is fixed to the base 41, and the rotating shaft of the driving motor 81 is coaxially fixed to the driving lead screw 83.

[0043] Referring to Figure 1 , One end of the cross beam 421 in the horizontal direction is fixed to the top end of the vertical beam 422. There are two groups of toggle seats 43 that slide away from or close to each other and are slidably arranged on the cross beam 421 on the side close to the production line, and the sliding direction of the toggle seats 43 is the horizontal direction. A sliding component 9 for driving the two groups of toggle seats 43 to move away from or close to each other is arranged on the cross beam 421, and the sliding component 9 includes a sliding bidirectional lead screw 91, a sliding motor 92 and a sliding slide rail 93. The two groups of toggle seats 43 are slidably connected to the cross beam 421 through the sliding slide rail 93, the two ends of the sliding bidirectional lead screw 91 are rotatably connected to the cross beam 421, and the two toggle seats 43 are respectively threadedly connected to the threads at both ends of the sliding bidirectional lead screw 91. The sliding motor 92 is fixed to the cross beam 421, and the rotating shaft of the sliding motor 92 is coaxially fixed to the sliding bidirectional lead screw 91.

[0044] Referring to Figure 1 , A toggle arm 44 is arranged on the toggle seat 43, the toggle arm 44 extends in the direction of approaching each other on the toggle seat 43, and there is a gap for accommodating the workpiece 7 between the toggle arm 44 and the cross beam 421. A guard plate 45 is fixed to the bottom of the toggle arm 44, the cross section of the guard plate 45 in the horizontal direction is U-shaped, and the U-shaped openings of the guard plates 45 of the two toggle arms 44 face each other. An inclined plate 46 is fixed to the bottom of the guard plate 45, and the inclined plates 46 at the bottoms of the two toggle arms 44 extend downward close to each other.

[0045] Referring to Figure 1 , A buffer plate 47 is arranged on one side close to each other in the middle of the two guard plates 45. The buffer plate 47 extends obliquely downward in the direction of approaching each other. When the two inclined plates 46 are in the closest position to each other, there is a falling object gap between the two buffer plates 47. The horizontal height position of the buffer plate 47 is located below the two workpieces 7 at the high position on the hanging rod 12. When the toggle arm 44 drives the two workpieces 7 at the high position to break away from the hanging rod 12, the workpieces 7 fall on the two buffer plates 47; when the toggle arm 44 drives the two workpieces 7 at the low position to break away from the hanging rod 12, the workpieces 7 fall on the inclined plates 46. Buffer pads are arranged on the top surfaces of the inclined plates 46 and the buffer plate 47, and the buffer pads are felt pads, so that the workpieces 7 are not easily damaged after falling.

[0046] A material collection basket 6 is provided below the crossbeam 421 . When the support column 42 slides away from the rack body 1 , the material collection basket 6 is located below the two inclined plates 46 , so as to conveniently catch the workpiece 7 that falls from between the two inclined plates 46 .

[0047] The implementation principle of the unloading mechanism for the metal workpiece 7 on the rack body 1 of the embodiment of the present application is as follows: a hole is provided on the workpiece 7 for the end of the hanging rod 12 to pass through, and the workpiece 7 is not easy to fall off the hanging rod 12 due to friction. When the workpiece 7 on the rack body 1 needs to be unloaded after being subjected to processes such as powder spraying, heating, painting, and drying, it is moved to the unloading area, and the winding positioning belt 5 abuts against the stabilizing ring 3. If the arc surface of the stabilizing ring 3 abuts against the side wall of the stabilizing belt, the stabilizing ring 3 rotates until the stabilizing ring 3 rotates to abut against the stabilizing surface 31, and the stabilizing surface 31 and the positioning belt 5 slide and contact low, so that the positioning belt 5 remains abutting against the stabilizing surface 31 to achieve positioning. Then the unloading mechanism body located on both sides of the main rod 11 unloads the workpiece 7.

[0048] First, when the two toggle seats 43 are away from each other, the vertical beam 422 and the horizontal beam 421 move on the base 41 close to the main rod 11, and then the two toggle seats 43 slide close to each other until the workpiece 7 is located in the gap between the toggle arm 44 and the horizontal beam 421, and then the vertical beam 422 moves away from the main rod 11, and the toggle arm 44 toggle the workpiece 7 and then separates it from the hanging rod 12, and the two high-positioned workpieces fall on the buffer plate 47, and the two low-positioned workpieces 7 fall on the inclined plate 46. When the inclined plate 46 moves to the top of the aggregate basket 6, the inclined plate 46 separates. Since the length of the buffer plate 47 is less than that of the inclined plate 46, when the inclined plate 46 is halfway separated, the workpiece 7 on the buffer plate 47 falls on the inclined plate 46. After the inclined plate 46 continues to separate, all the workpieces 7 on the inclined plate 46 fall into the aggregate frame. The empty hanger body 1 continues to move to the loading position of the workpiece 7 for manual loading and enters the next round of processing.

[0049] In summary, the present application solution first positions the workpiece 7 and then automatically unloads the workpiece 7 on the rack body 1. This prevents the workpiece 7 from being damaged, saves labor costs, and has a simple structure and is easy to use.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
