Description

Technical Field

[0001] The utility model belongs to the technical field of stamping, and in particular relates to a material taking device for a stamping workpiece. Background Art

[0002] Stamping is a process that uses rapid impact to deform metal on a punch press. Stamping and punching is a common technical means of mechanical processing. The punching equipment is used to punch holes in the carrier plate to obtain the finished workpiece. After the existing stamping equipment completes the punching, it is generally separated and recycled by a robot or manually.

[0003] With the development of science and technology, people's requirements for stamping workpieces are gradually increasing. The number of punching holes on the same carrier plate is increasing, the inner diameter of the punched holes is gradually decreasing, and the requirements for the smoothness of the punched cross-section are increasing. Therefore, it is necessary to use a fine-blanking punching machine to complete the stamping operation of complex workpieces. After fine-blanking, the waste sheet will be embedded in the punched holes, and it is difficult to use a robot to separate the workpiece and the waste sheet. In addition, a large amount of debris and waste will be generated near the workpiece after stamping. When the workpiece is moved, these debris and waste can easily scratch the surface of the workpiece, affecting the molding quality of the workpiece. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the utility model provides a material taking device for stamping workpieces. By installing the material taking device between the upper die and the lower die of the fine blanking machine, the blowing mechanism first blows away the debris and waste materials near the stamping workpiece from the stamping workpiece to prevent these debris and waste materials from scratching the surface of the stamping workpiece, thereby ensuring the molding quality of the workpiece. Then the pushing mechanism pushes the stamping workpiece and the waste sheet material embedded in the punching hole of the stamping workpiece from the lower die to the conveyor, and the conveyor is transported to the vibrating separation screen to achieve separation of the stamping workpiece and the waste sheet material.

[0005] The utility model is realized by the following technical solutions:

[0006] A material taking device for stamping workpieces is installed between the upper die and the lower die of a fine-blanking machine. The upper die and the lower die can move toward each other to punch holes in the bearing plate located above the lower die to form a stamping workpiece. The material taking device includes a blowing mechanism, a pushing mechanism and a conveyor. The blowing mechanism is located on one side of the lower die. The blowing mechanism includes a support frame and a blowing pipe installed on the support frame. The blowing pipe points to the stamping workpiece to blow away the debris and waste near the stamping workpiece. The pushing mechanism is located below the blowing mechanism. The pushing mechanism includes a base and a pushing cylinder installed on the base. The pushing cylinder is horizontally arranged, and the pushing cylinder and the stamping workpiece are in the same horizontal plane. The conveyor is located on the side of the lower die away from the blowing mechanism. The conveyor includes a conveyor belt and a material receiving plate connected to the conveyor belt. The material receiving plate is built on the lower die. The conveyor belt can convey the stamping workpiece and the waste plate to the vibrating separation screen to achieve screening of the stamping workpiece and the waste plate.

[0007] Furthermore, the support frame includes two vertical poles, a horizontal pole located between the two vertical poles, and a connector. The connector is provided with a vertical hole that is sleeved to the vertical poles and a horizontal hole that is sleeved to the horizontal pole. The connector is also provided with an adjustment groove connecting the vertical holes and the horizontal holes and a threaded hole passing through the adjustment groove. The adjusting bolt is screwed into the threaded hole to adjust the aperture of the vertical hole or the horizontal hole, thereby realizing the adjustment of the height position of the horizontal pole and the blowing pipe installed on the horizontal pole.

[0008] Furthermore, a connector is provided between the air blowing pipe and the cross bar of the support frame. The connector is provided with a vertical hole that is sleeved to the air blowing pipe and a cross hole that is sleeved to the cross bar. The connector is also provided with an adjustment groove that connects the vertical hole and the cross hole and a threaded hole that passes through the adjustment groove. The adjusting bolt is screwed into the threaded hole to adjust the aperture of the vertical hole or the cross hole, thereby adjusting the deflection angle of the air blowing pipe relative to the cross bar, so as to adjust the direction of the airflow blown out of the air blowing pipe.

[0009] Furthermore, a plurality of air blowing pipes are provided along the extension direction of the cross bar, which are helpful to fully blow away the debris and waste materials near the stamping workpiece and prevent the debris and waste materials from scratching the surface of the stamping workpiece when the stamping workpiece moves.

[0010] Furthermore, the blowing mechanism also includes a controller connected to the fine blanking machine and a high-pressure air pump connected to the controller. The high-pressure air pump is connected to the blowing pipe by a pipeline to provide a power airflow for the blowing pipe.

[0011] Furthermore, the pushing cylinder is connected with the controller data to improve the automation level of the material taking device.

[0012] Furthermore, the pushing mechanism also includes a pushing plate fixed to the front of the pushing cylinder, and the side of the pushing plate close to the stamping workpiece is provided with an arc surface matching the stamping workpiece, so as to facilitate pushing the stamping workpiece and waste plate above the lower mold away to the conveyor.

[0013] Furthermore, the surface of the push plate is coated with a Teflon coating, which has a low friction coefficient and good wear resistance. Coating the surface of the push plate with the Teflon coating helps to reduce the movement resistance of the push plate relative to the lower mold.

[0014] Furthermore, an upper punching rod is installed in the upper mold, and a lower punching rod vertically aligned with the upper punching rod is installed in the lower mold. When the supporting plate is punched, the upper punching rod abuts against the top surface of the supporting plate, and the lower punching rod abuts against the bottom surface of the supporting plate, thereby improving the punching quality of the supporting plate.

[0015] Beneficial effects of the utility model:

[0016] By installing the material taking device between the upper die and the lower die of the fine blanking machine, the blowing mechanism first blows away the debris and waste materials near the stamping workpiece to prevent these debris and waste materials from scratching the surface of the stamping workpiece and ensure the forming quality of the workpiece. Then the pushing mechanism pushes the stamping workpiece and the waste sheet embedded in the punching hole of the stamping workpiece from the lower die to the conveyor, and the conveyor is transported to the vibrating separation screen to separate the stamping workpiece from the waste sheet.

[0029] like Figures 1 to 6The material-removing device for a stamped workpiece shown is installed between the upper die 11 and the lower die 12 of the fine-blanking machine 1. The upper die 11 and the lower die 12 can move toward each other to punch the supporting plate located above the lower die 12 to form a stamped workpiece 2. The material-removing device includes a blowing mechanism 3, a pushing mechanism 4, and a conveyor 5. The blowing mechanism 3 is located on one side of the lower die 12. The blowing mechanism 3 includes a support frame 31 and a blowing pipe 32 installed on the support frame 31. The blowing pipe 32 points to the stamped workpiece 2 to blow away the debris and waste near the stamped workpiece 2. The pushing mechanism 4 is located below the blowing mechanism 3. The pushing mechanism 4 includes a base 41 and a pushing cylinder 42 installed on the base 41. The pushing cylinder 42 is horizontally arranged, and the pushing cylinder 42 and the stamped workpiece 2 are in the same horizontal plane. The conveyor 5 is located on the side of the lower mold 12 away from the blowing mechanism 3. The conveyor 5 includes a conveyor belt 51 and a receiving plate 52 connected to the conveyor belt 51. The receiving plate 52 is extended to the lower mold 12. The conveyor belt 51 can convey the stamping workpiece 2 and the waste plate to the vibrating separation screen to achieve screening of the stamping workpiece 2 and the waste plate.

[0030] In one embodiment, first, the carrier plate is placed at the punching position of the lower die 12. The fine punching machine 1 is started, and the upper die 11 moves vertically downward to abut against the carrier plate. Specifically, the upper punching rod of the upper die 11 abuts against the top surface of the carrier plate, and the lower punching rod of the lower die 12 abuts against the bottom surface of the carrier plate. The upper punching rod and the lower punching rod move downward synchronously to punch the carrier plate, so that the carrier plate is completely in a compressive stress state during the punching process, thereby improving the punching quality of the carrier plate. After the punching is completed, the upper punching rod moves vertically upward to the initial position, and the lower punching rod synchronously retreats upward to the initial position and drives the punched waste sheet material to retreat to the punching position of the carrier plate, that is, the punching hole of the stamped workpiece 2 after the punching is completed is embedded with the waste sheet material. During the punching process, a certain amount of debris and waste will be generated near the stamped workpiece 2. In order to prevent these debris and waste materials from scratching the stamped workpiece 2. After the stamping is completed, the controller first controls the air blowing pipe 32 to blow air toward the stamped workpiece 2 to blow the debris and waste near the stamped workpiece 2 away from the stamped workpiece 2. Then, the pushing cylinder 42 of the pushing mechanism 4 moves horizontally toward the stamped workpiece 2 to push the stamped workpiece 2 and the waste sheet embedded in the stamped workpiece 2 away from the lower die 12 to the conveyor 5. The conveyor 5 moves the stamped workpiece 2 and the waste sheet embedded in the stamped workpiece 2 to the vibrating separation screen through the conveyor belt 51 to separate the stamped workpiece 2 and the waste sheet embedded in the stamped workpiece 2.

[0031] In one embodiment, the workpiece to be punched can be directly placed on the location to be punched above the lower die 12 to perform the punching operation on the workpiece.

[0032] It should be noted that the air blow pipe 32 can blow the debris and waste materials onto the conveyor belt 51 of the conveyor 5, and the conveyor belt 51 first transports the debris and waste materials. Then the push cylinder 42 pushes the stamping workpiece 2 onto the conveyor belt 51, and the conveyor belt 51 transports it. Since the air blow pipe 32 is started before the push cylinder 42, there will be a certain distance between the debris and waste materials on the conveyor belt 51 and the stamping workpiece 2, which effectively prevents the debris and waste materials from scratching the stamping workpiece 2. It should also be noted that during the process of the material taking device taking the stamping workpiece 2, a small amount of debris and waste materials or waste plates may still scratch the stamping workpiece 2. Before the push cylinder 42 is started, starting the air blow pipe 32 first can blow most of the debris and waste materials away from the stamping workpiece 2. Compared with not setting the air blow pipe 32, the stamping workpiece 2 can be better protected.

[0033] Preferably, the support frame 31 includes two vertical poles 311, a horizontal pole 312 located between the two vertical poles 311, and a connector 33. The connector 33 is provided with a vertical hole 331 that is sleeved to the vertical pole 311 and a horizontal hole 332 that is sleeved to the horizontal pole 312. The connector 33 is also provided with an adjustment groove 333 connecting the vertical hole 331 and the horizontal hole 332, and a threaded hole passing through the adjustment groove 333. The adjustment bolt 334 is screwed into the threaded hole to adjust the aperture of the vertical hole 331 or the horizontal hole 332, so as to adjust the height position of the horizontal pole 312 and the blowing pipe 32 installed on the horizontal pole 312.

[0034] In one embodiment, the vertical hole 331 of the connector 33 is sleeved to the vertical rod 311, so that the connector 33 can move relative to the vertical rod 311 in the extension direction of the vertical rod 311, thereby adjusting the height of the cross bar 312 installed on the connector 33 and the air blowing pipe 32 installed on the cross bar 312. After adjusting the height positions of the air blowing pipe 32 and the cross bar 312, screw the adjusting bolt 334 into the threaded hole, as shown in FIG. Figure 5 As shown, tighten the adjusting bolt 334, the connector 33 is deformed to reduce the width of the adjusting slot 333, thereby reducing the diameter of the entire vertical hole 331, thereby achieving the fastening of the opposing rod 311 and the connector 33. The connection method between the cross bar 312 and the cross hole 332 is similar.

[0035] Preferably, a connector 33 is provided between the air blowing pipe 32 and the cross bar 312 of the support frame 31, and the connector 33 is provided with a vertical hole 331 which is sleeved to the air blowing pipe 32 and a cross hole 332 which is sleeved to the cross bar 312. The connector 33 is also provided with an adjustment groove 333 which connects the vertical hole 331 and the cross hole 332, and a threaded hole which passes through the adjustment groove 333. The adjustment bolt 334 is screwed into the threaded hole to adjust the aperture of the vertical hole 331 or the cross hole 332, so as to adjust the deflection angle of the air blowing pipe 32 relative to the cross bar 312, so as to adjust the direction of the airflow blown out of the air blowing pipe 32.

[0036] Preferably, a plurality of air blowing pipes 32 are provided along the extension direction of the cross bar 312 , which helps to fully blow away the debris and waste materials near the stamped workpiece 2 and prevent the debris and waste materials from scratching the surface of the stamped workpiece 2 when the stamped workpiece 2 moves.

[0037] Preferably, the blowing mechanism 3 further includes a controller connected to the fine blanking machine 1 and a high-pressure air pump connected to the controller. The high-pressure air pump is connected to the blowing pipe 32 by a pipeline to provide a power airflow for the blowing pipe 32 .

[0038] In one embodiment, the high-pressure air pump adopts an existing air pump structure, and the connection method between the air blowing pipe 32 and the high-pressure air pump belongs to the existing technology and will not be described in detail here.

[0039] Preferably, the pushing cylinder 42 is connected to the controller data to improve the automation level of the material taking device.

[0040] Preferably, the pushing mechanism 4 also includes a pushing plate 43 fixed to the front of the pushing cylinder 42, and the side of the pushing plate 43 close to the stamping workpiece 2 is provided with an arc surface 431 matching the stamping workpiece 2, so as to facilitate pushing the stamping workpiece 2 and the waste plate above the lower mold 12 away to the conveyor 5.

[0041] Preferably, the surface of the push plate 43 is coated with a Teflon coating, which has a low friction coefficient and good wear resistance. Coating the surface of the push plate 43 with the Teflon coating helps to reduce the movement resistance of the push plate 43 relative to the lower mold 12.

[0042] Preferably, an upper punching rod is installed in the upper mold 11, and a lower punching rod vertically aligned with the upper punching rod is installed in the lower mold 12. When the supporting plate is punched, the upper punching rod abuts against the top surface of the supporting plate, and the lower punching rod abuts against the bottom surface of the supporting plate, thereby improving the punching quality of the supporting plate.
