Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a continuous sheet metal part punching device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. The processing technology includes the stamping process of sheet metal. Since sheet metal parts are small, continuous stamping dies are often used to stamp sheet metal. One machine can process sheet metal into the required sheet metal parts. When the sheet metal strip is extended into the upper template of the existing continuous stamping die, the positioning of the sheet metal strip is too loose, which can easily cause the sheet metal strip to deviate. The deviation will affect the shape of the stamping, thereby affecting the quality of the produced sheet metal parts. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and provide a continuous sheet metal stamping device.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a continuous sheet metal stamping device, including a base, the top of the base is fixedly connected with a pad, the top of the pad is fixedly connected with the lower template, the upper surface of the lower template is provided with a sliding groove, the outer surface of the base is fixedly connected with a positioning column, the top of the base is fixedly connected with the blanking table, the top of the positioning column is movably connected with a movable column, the bottom of the movable column is fixedly connected with a spring, the inner wall of the sliding groove is provided with a rubber belt, the outer surface of the rubber belt is fixedly connected with a magnetic block, the outer surface of the rubber belt is movably connected with a transmission wheel, one side of the transmission wheel is movably connected to a fixed shaft through a bearing, and the other side of the transmission wheel is provided with a driving machine, the top of the driving machine is fixedly connected with a fixing plate, and the outer surface of the fixing plate is connected with a bolt through a threaded hole.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] The utility model designs a sliding groove, which runs through the lower template, so as to facilitate the installation of the rubber belt and the magnetic block. The two ends of the sliding groove are sliding surfaces adapted to the rotation of the rubber belt, thereby reducing the resistance of the rubber belt transmission. The depth of the sliding groove makes the top of the magnetic block and the top of the lower template in the same plane, so as to prevent the magnetic block from being too high and affecting the quality of the sheet metal stamping. The design of the positioning column, the movable column and the spring is conducive to buffering the speed of the downward pressure of the upper template, and plays a positioning role in the stamping of the upper template. The designed blanking table facilitates the sheet metal parts that have been stamped and cut to slide from the blanking table. The rubber belt is arranged on the inner wall of the sliding groove, and the rubber belt is a closed rubber ring belt, which is located on the outside of the pad and the base. The rubber belt rotates on the inner wall of the sliding groove, thereby driving the magnetic block arranged on the surface of the rubber belt, so that the magnetic block moves continuously to the sliding The top of the groove makes it convenient for the magnetic block to drive the continuously stamped sheet metal to move continuously to one end under the action of suction. There are multiple magnetic blocks, which are equidistantly distributed on the outer surface of the rubber belt, which can effectively play the transmission role of the magnetic block. By cooperating with the shielding effect of the positioning groove, it prevents the sheet metal from shifting left and right during the forward movement. The shift will cause the stamping shift, and the stamping shift will affect the quality of the product. This design is to assist the sheet metal to be more stably attached to the lower template and move forward. The inner wall of the drive wheel is designed to be movably connected to the inner side of the rubber belt. The inner wall of the drive wheel has a frosted surface, which increases the friction between the rubber belt and the drive wheel, so that the drive wheel can be transmitted more effectively. A fixed shaft connected to the drive wheel by a bearing on one side is mainly used to support and stabilize the drive wheel to prevent the drive wheel from shifting. The drive motor connected on the other side provides a power source for the drive wheel. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0019] Example 1

[0020] like Figures 1-4 As shown, the utility model provides a technical solution: a continuous sheet metal stamping device, including a base 1, a pad 2 is fixedly connected to the top of the base 1, a lower template 3 is fixedly connected to the top of the pad 2, a sliding groove 4 is provided on the upper surface of the lower template 3, a positioning column 7 is fixedly connected to the outer surface of the base 1, a blanking table 8 is fixedly connected to the top of the base 1, a movable column 9 is movably connected to the top of the positioning column 7, a spring 10 is fixedly connected to the bottom of the movable column 9, a rubber belt 11 is provided on the inner wall of the sliding groove 4, a magnetic block 12 is fixedly connected to the outer surface of the rubber belt 11, a transmission wheel 13 is movably connected to the outer surface of the rubber belt 11, and one side of the transmission wheel 13 A fixed shaft 14 is movably connected through a bearing, and a driving machine 15 is provided on the other side of the transmission wheel 13. The top of the driving machine 15 is fixedly connected to a fixing plate 16, and the outer surface of the fixing plate 16 is connected with a bolt 17 through a threaded hole. The outer surface of the positioning column 7 is provided with a groove, and the bottom of the spring 10 is fixedly connected to the bottom of the groove. The output end of the driving machine 15 is fixedly connected to one side of the transmission wheel 13, and the top of the fixing plate 16 is fixedly connected to the top of the base 1 through the bolt 17. The bottom of the base 1 is provided with a runner groove, and the outer surface of the transmission wheel 13 is movably connected to the bottom of the base 1 through the runner groove. The top of the fixed shaft 14 is fixedly connected to the bottom of the base 1.

[0021] The two ends of the sliding groove 4 are sliding surfaces adapted to the rotation of the rubber belt 11, thereby reducing the resistance of the rubber belt 11 to the transmission. The depth of the sliding groove 4 is just enough to make the top of the magnetic block 12 and the top of the lower template 3 in the same plane to prevent the magnetic block 12 from being too high and affecting the quality of the sheet metal stamping. The positioning column 7, the movable column 9 and the spring 10 are designed to buffer the speed of the upper template pressing down, and play a positioning role in the stamping of the upper template. The designed blanking table 8 is convenient for the sheet metal part cut by stamping to slide from the blanking table 8. The rubber belt 11 is provided on the inner wall of the sliding groove 4. The rubber belt 11 is a closed rubber ring belt, which is located on the outside of the pad 2 and the base 1. The rubber belt 11 rotates on the inner wall of the sliding groove 4, thereby driving the magnetic block 12 provided on the surface of the rubber belt 11, so that the magnetic block 12 moves continuously. The magnetic blocks 12 are arranged in a plurality of manners and are evenly distributed on the outer surface of the rubber belt 11, so that the transmission function of the magnetic blocks 12 can be effectively exerted. By cooperating with the shielding function of the positioning groove 6, the sheet metal parts are prevented from shifting left and right during the forward movement. The shifting will cause the stamping shift, and the stamping shift will affect the quality of the product. This design is to assist the sheet metal parts to be more stably attached to the lower template 3 and advance. The inner wall of the transmission wheel 13 is movably connected to the inner side of the rubber belt 11 by design. The inner wall of the transmission wheel 13 has a frosted surface, which increases the friction between the rubber belt 11 and the transmission wheel 13, so that the transmission wheel 13 can be more effectively transmitted. A fixed shaft 14 connected to one side of the transmission wheel 13 by a bearing is mainly used to support and stabilize the transmission wheel 13 to prevent the transmission wheel 13 from shifting. The driving machine 15 connected to the other side provides a power source for the transmission wheel 13.

[0022] Example 2

[0023] like Figure 1 As shown, a positioning block 5 is fixedly connected to the outer surface of the lower template 3 , and a positioning groove 6 is formed on the outer surface of the positioning block 5 . The positioning block 5 is arranged on one side of the sliding groove 4 .

[0024] In this embodiment, the positioning block 5 fixedly connected to the outer surface of the lower template 3 has a positioning function for the continuously moving sheet metal part. The sliding groove 4 opened on its outer surface together with the rubber belt 11 and the magnetic block 12 constitute a structure to prevent the sheet metal part from deflecting. The design of the sliding groove 4 is that it is opened in the middle and lower part of the outer surface of the positioning block 5. The top inner wall of the sliding groove 4 can prevent the sheet metal part from warping up.

[0025] Working principle:

[0026] like Figures 1-4As shown, when a sheet metal part is transmitted to the lower template 3, the transmission wheel 13 and the rubber belt 11 start to rotate synchronously under the drive of the driving machine 15, and the output end of the driving machine 15 drives the transmission wheel 13, and the other end of the transmission wheel 13 rotates smoothly under the support of the bearing. Under the influence of the pressure and friction between the transmission wheel 13 and the rubber belt 11, the rubber belt 11 and the magnetic block 12 are driven to rotate. When the magnetic block 12 rotates to the upper surface of the lower template 3, it absorbs the transmitted sheet metal part, positions it on the outer surface of the lower template 3, and is stuck in the positioning groove 6 at the positioning block 5, ensuring that the sheet metal part moves forward smoothly, making the stamping position of the sheet metal part more accurate, and improving the quality of the product.
