Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a die stamping material receiving device. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profile, causing plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0003] During the stamping process, stamped products sometimes fall from the blanking hole at the bottom of the die. It is necessary to collect the stamped products at the blanking hole. The commonly used collection method is to place a collection box at the bottom of the blanking hole to collect the stamped products. Although the operation is convenient, for some products with strict appearance requirements, collecting them in a collection box can easily cause scratches and other defects on the product's appearance, affecting the subsequent use of the product. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, this utility model provides a die stamping material receiving device, which can realize the individual collection of stamped products, avoid the products from contacting each other and causing scratches on the appearance surface, resulting in product defects. At the same time, it can also inspect the products and reject defective products that have been stamped and deformed.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A die stamping and receiving device includes a stamping table, a support on the stamping table, an upper die movably mounted on the support via a pushing device, a lower die corresponding to the bottom of the upper die, a support base between the lower die and the stamping table, a first conveyor belt passing through the support base, a plurality of receiving boxes arranged on the first conveyor belt, a dropping hole communicating with the lower die on the support base, a first intercepting component installed opposite to the dropping hole, the receiving boxes intercepted by the two first intercepting components corresponding to the dropping hole, an optical detection component installed on the support base at the output end of the first conveyor belt, a scrap rejection support frame installed on the stamping table near the optical detection component, the first conveyor belt passing through the scrap rejection support frame, a second intercepting component installed on the scrap rejection support frame above the first conveyor belt, a side pushing component installed on one side of the scrap rejection support frame near the second intercepting component, and a guide groove corresponding to the side pushing component on the other side of the scrap rejection support frame.

[0007] As an improved technical solution, the support base includes a first support plate and a second support plate. The first support plate is connected to the lower die, and the second support plate is connected to the stamping table. A plurality of support blocks are arranged and installed between the first support plate and the second support plate.

[0009] As an improved technical solution, a set of guide plates is installed on the support base at the input end of the first conveyor belt. The set of guide plates has a trumpet-shaped structure and is installed at the bottom of the first support plate.

[0010] As an improved technical solution, the first interception component includes a rotary cylinder, which is installed at the bottom of the first support plate. A first interception plate is installed on the rotary table of the rotary cylinder. The rotary cylinder drives the first interception plate to swing vertically and intercept and limit the receiving box.

[0011] As an improved technical solution, the optical detection component includes a connecting bracket, which is mounted on the first support plate. A detection camera is mounted on the connecting bracket, and a light source is mounted at the bottom of the detection camera. The illumination direction of the light source and the detection direction of the detection camera are both directed toward the first conveyor belt.

[0012] As an improved technical solution, the second interception component includes a support plate that spans the first conveyor belt and is mounted on the waste rejection support frame at both ends. A first cylinder is mounted on the support plate, and the piston rod of the first cylinder passes through the support plate and is connected to the second interception plate. The first cylinder pushes the second interception plate to move vertically and intercepts and limits the receiving box.

[0013] As an improved technical solution, the side-pushing assembly includes a second cylinder, which is mounted on the waste rejection support frame. The piston rod of the second cylinder passes through the waste rejection support frame and is connected to a push block. The push block corresponds to the receiving box intercepted by the second interception assembly and pushes the receiving box to the guide trough.

[0014] As an improved technical solution, an optical sensor is installed on the side of the support plate near the optical detection component. The optical sensor is connected to a PLC controller, and the PLC controller is connected to the first cylinder and the second cylinder.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] By setting up a stamping table with a support, an upper die is movably mounted on the support via a pushing device. A lower die is correspondingly mounted at the bottom of the upper die.

A support base is provided between the lower die and the stamping table. A first conveyor belt is provided inside the support base. Several receiving boxes are arranged on the first conveyor belt. The support base has a blanking hole that communicates with the lower die. A first intercepting component is installed opposite to the blanking hole. The receiving boxes intercepted by the two first intercepting components correspond to the blanking holes. The receiving boxes that collect the stamped products can be conveyed by the first conveyor belt. The first intercepting components intercept the receiving boxes on the first conveyor belt, stopping them directly below the blanking hole, so that the punched stamped product can fall directly into the receiving box and be conveyed to the next process by the first conveyor belt.

[0017] An optical detection component is installed on the support base at the output end of the first conveyor belt. The optical detection component can detect the stamped products in the receiving box and identify defective products with stamping deformation.

The second interception component can intercept the receiving box of defective products detected by the optical detection component, and the side push component pushes the receiving box of defective products through the guide groove to the scrap collection process. In this way, the stamped products can be collected individually, avoiding the problem of product surface scratches caused by product contact and product defects. At the same time, the products can be inspected and defective products with stamping deformation can be rejected.

[0018] In summary, this utility model provides a die stamping material receiving device that can collect stamped products individually, avoiding scratches on the surface caused by contact between products, thus preventing product defects. At the same time, it can also inspect the products and reject defective products that have been deformed during stamping. Attached Figure Description

[0026] 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.

[0028] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0029] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0030] Combination Figures 1-4 As shown, a die stamping receiving device includes a stamping table 1, a support 2 on the stamping table 1, and an upper die 4 movably mounted on the support 2 via a pushing device 3. The pushing device 3 can be a hydraulic cylinder. A lower die 5 is correspondingly provided at the bottom of the upper die 4. The pushing device 3 pushes the upper die 4 downward and cooperates with the lower die 5 to punch the material. The punched product falls down through the blanking hole. The side of the punched product that contacts the upper die 4 is usually the appearance surface, and the other side is the burr surface. It is usually required that there are no scratches, marks or other defects on the appearance surface. In addition, sometimes due to material supply problems or stamping die problems, the stamped product may sometimes have defects such as deformation or surface damage.

[0031] A support base 6 is provided between the lower die 5 and the stamping table 1. A first conveyor belt 7 is installed inside the support base 6. Several receiving boxes 8 are arranged on the first conveyor belt 7. The receiving boxes 8 can be automatically placed on the first conveyor belt 7 by a mechanical gripper or manually. The support base 6 is provided with a dropping hole that communicates with the lower die 5. A first intercepting component 9 is installed opposite to the dropping hole. The receiving boxes 8 intercepted by the two first intercepting components 9 correspond to the dropping holes. The receiving boxes 8 that collect stamped products can be intermittently conveyed by the first conveyor belt 7. The receiving boxes 8 on the first conveyor belt 7 are intercepted by the first intercepting components 9 and stop directly below the dropping holes. This allows the stamped products after stamping to fall directly into the receiving boxes 8 and be conveyed to the next process by the first conveyor belt 7. The inner cavity of the receiving box 8 is lined with soft material to prevent the stamped products from bouncing or flipping when they fall, so that the outer surface of the stamped products always faces upwards, which is convenient for subsequent appearance inspection.

[0032] An optical detection component 10 is installed on the support base 6 at the output end of the first conveyor belt 7. The optical detection component 10 can detect the stamped products in the receiving box 8 and identify defective products such as stamping deformation and crushing. A scrap rejection support frame 11 is installed on the stamping table 1 near the optical detection component 10. The first conveyor belt 7 passes through the scrap rejection support frame 11. A second interception component 12 is provided on the scrap rejection support frame 11 above the first conveyor belt 7. A side push component is provided on one side of the scrap rejection support frame 11 near the second interception component 12. 13. On the other side of the scrap support frame 11, there is a guide groove 14 corresponding to the side push assembly 13. The second interception assembly 12 can intercept the receiving box 8 of defective products detected by the optical detection assembly 10, and push the receiving box 8 of defective products through the guide groove 14 to the scrap collection process through the side push assembly 13. In this way, the stamping products can be collected individually, avoiding the problem of product defects caused by contact between products. At the same time, the products can be inspected and defective products with stamping deformation can be removed.

[0033] Combination Figures 1-4 As shown, the support base 6 includes a first support plate 601 and a second support plate 602. The first support plate 601 is bolted to the lower mold 5, and the second support plate 602 is bolted to the stamping table 1. Several support blocks 603 are arranged and installed between the first support plate 601 and the second support plate 602 by bolt connection.

[0034] The first conveyor belt 7 is located between the first support plate 601 and the second support plate 602. By setting the support block 603, a certain space is provided between the first support plate 601 and the second support plate 602, which facilitates the conveying of the first conveyor belt 7 and the collection of the punched products.

[0035] Combination Figures 1-4 As shown, a guide plate group 15 is installed on the support base 6 at the input end of the first conveyor belt 7. The guide plate group 15 has a trumpet-shaped structure and is installed at the bottom of the first support plate 601. The guide plate group 15 guides the receiving box 8 placed on the first conveyor belt 7 so that the receiving box 8 is located in the middle of the first conveyor belt 7 and is directly below the dropping hole.

[0036] Combination Figure 3As shown, the first interception component 9 includes a rotary cylinder 901, which is installed at the bottom of the first support plate 601. A first interception plate 902 is installed on the rotating platform of the rotary cylinder 901. The rotary cylinder 901 drives the first interception plate 902 to swing vertically and intercept and limit the receiving box 8. The rotary cylinder 901 can drive the first interception plate 902 to rotate vertically and rotate the first interception plate 902 from a horizontal state to a vertical state, thereby realizing the interception and positioning of the receiving box 8, so that the receiving box 8 is located directly below the discharge hole, which is convenient for receiving materials.

[0037] In addition, the rotary cylinder 901 also needs to be connected to the controller signal of the pushing device 3 of the stamping die. Before the pushing device 3 pushes the upper die 4 downward to achieve the punching, the rotary table of the rotary cylinder 901 is activated first, driving the first intercepting plate 902 to rotate and intercept the receiving box 8 on the first conveyor belt 7 directly below the dropping hole, so that the punched product can fall directly into the receiving box 8.

[0038] Combination Figure 1 , Figure 3 and Figure 4 As shown, the optical inspection assembly 10 includes a connecting bracket 1001, which is bolted to the first support plate 601. An inspection camera 1002 is mounted on the connecting bracket 1001, and a light source 1003 is mounted on the bottom of the inspection camera 1002. The illumination direction of the light source 1003 and the detection direction of the inspection camera 1002 are both towards the first conveyor belt 7. The inspection camera 1002 performs optical inspection on the stamped products in the receiving box 8 and transmits the information of non-compliance to the PLC controller. The light source 1003 is mainly a lamp, which illuminates the stamped products to make the inspection camera 1002 detect them more clearly.

[0039] Combination Figure 1 , Figure 3 and Figure 4 As shown, the second interception component 12 includes a support plate 1201, which spans the first conveyor belt 7 and is mounted on the waste rejection support frame 11 at both ends. A first cylinder 1202 is mounted on the support plate 1201. The piston rod of the first cylinder 1202 passes through the support plate 1201 and is connected to the second interception plate 1203. The first cylinder 1202 pushes the second interception plate 1203 to move vertically and intercepts and limits the receiving box 8. The extension of the piston rod of the first cylinder 1202 can drive the second interception plate 1203 to move vertically, thereby intercepting the receiving box 8 conveyed on the first conveyor belt 7.

[0040] Combination Figure 1 , Figure 3 and Figure 4As shown, the side-push assembly 13 includes a second cylinder 1301, which is mounted on the scrap rejection support frame 11. The piston rod of the second cylinder 1301 passes through the scrap rejection support frame 11 and is connected to a push block 1302. The push block 1302 corresponds to the receiving box 8 intercepted by the second interception assembly 12 and pushes the receiving box 8 to the guide trough 14. The extension of the piston rod of the second cylinder 1301 can push the push block 1302 to move. The push block 1302 pushes the receiving box 8 intercepted by the second interception assembly 12 to the guide trough 14, and the defective products are transported to the scrap collection process through the guide trough 14. The scrap collection process can be a scrap collection box or a scrap collection conveyor line.

[0041] Combination Figure 3 and Figure 4 As shown, an optical sensor 16 is installed on the side of the support plate 1201 near the optical detection component 10. The optical sensor 16 is connected to the PLC controller, which is connected to the first cylinder 1202 and the second cylinder 1301. The optical sensor 16 can detect the receiving box 8 being conveyed on the first conveyor belt 7 and transmit the information to the PLC controller. At the same time, the PLC controller can also obtain the detection information transmitted by the optical detection component 10, thereby controlling the first cylinder 1202 and the second cylinder 1301 to operate, intercept the receiving box 8 containing the detected defective products, and push it to the side of the guide chute 14.

[0042] For ease of understanding, the working process of this embodiment is described below:

[0043] Combination Figures 1-4 As shown, firstly, the rotary cylinder 901 of the first intercepting component 9 is activated. The rotary table of the rotary cylinder 901 drives the first intercepting plate 902 to rotate downwards and intercepts and positions the receiving box 8 on the first conveyor belt 7, so that the receiving box 8 is directly below the dropping hole. Then, the pushing device 3 pushes the upper die 4 to move downwards. During the movement, the upper die 4 cooperates with the lower die 5 to stamp the material. The stamped product falls into the receiving box 8 of the first conveyor belt 7 through the dropping hole. After that, the rotary table of the rotary cylinder 901... Reverse rotation: the first conveyor belt 7 transports the receiving box 8 to the optical inspection component 10. The optical inspection component 10 inspects the stamped products in the receiving box 8. When a defective product is found, the defect information is transmitted to the PLC controller. The PLC controller controls the piston rod of the first cylinder 1202 to extend and pushes the second interceptor plate 1203 to intercept the receiving box 8 on the first conveyor belt 7. Then, the PLC controller controls the piston rod of the second cylinder 1301 to extend and pushes the push block 1302 to move. The push block 1302 pushes the receiving box 8 into the guide trough 14 and transports it to the waste collection process through the guide trough 14. After that, the first cylinder 1202 and the second cylinder 1301 are controlled to return to their initial positions, while qualified products are transported to the next process by the first conveyor belt 7.

[0044] In summary, this utility model provides a die stamping material receiving device that can collect stamped products individually, avoiding scratches on the surface caused by contact between products, thus preventing product defects. At the same time, it can also inspect the products and remove defective products that have been deformed during stamping.
