Description

Technical Field

[0001] The utility model relates to the field of stamping machines, in particular to a waste separation device for stamped parts. Background Technique

[0002] A stamping machine tool, abbreviated as a stamping machine, also known as a press, is a device used for pressure processing of materials. Its working principle is generally to drive the opening and closing of the upper die and the lower die under the action of stamping power by the machine tool, and then cut, punch, stretch and other shaping operations are performed on the raw materials between them to form stamped parts. According to the working principle of the press, it can be divided into mechanical presses and hydraulic presses. In the current stamping work process, some corner wastes will be generated due to stamping of metals. Usually, these corner wastes are cleaned manually, which is likely to pose a hazard to the personal safety of the cleaning personnel, and the time required for manual cleaning is also very long. At the same time, small metal chips and dust are not only not easy to clean but also not easy to separate. Therefore, the metal chips and dust are disposed of together, resulting in waste of resources. If the residual waste remains on the equipment, the waste will accumulate on the equipment and hinder the operation of the equipment.

[0003] At present, a Chinese patent with the authorization announcement number of CN104139127A discloses a blowing and discharging type stamping die machine, which includes a base. Above the base is provided a stamping device. The upper die is fixed on the stamping device, and the lower die is fixed on the base. A groove is provided in the upper die, and a protrusion cooperating with the groove is provided in the lower die. A push rod is provided on the stamping device, and a blowing device and a product collection tray are respectively provided on both sides of the base. The blowing and discharging type stamping die machine proposed by the present invention discharges the product by blowing, reduces the possibility of secondary damage to the formed product and the die, reduces the labor cost, improves the production efficiency, and at the same time reduces the possibility of injury to the operator during manual discharging.

[0004] The above-mentioned existing technical solutions have the following defects: The existing blanking method is very likely to cause waste to accumulate on the workbench, affecting the quality of the next stamping. Therefore, a more effective separation device is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a waste separation device for stamped parts to solve the problems existing in the above-mentioned prior art.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A waste separation device for stamped parts includes a stamping machine body. A die is provided on the stamping machine body. The die includes an upper die and a lower die. The lower die is arranged on a workbench. An extension part is arranged on the left side of the lower die. A material pushing device is arranged on the top of the lower die. An aggregate device is arranged on one side of the workbench;

[0008] The material pushing device includes a material pushing cylinder and a material pushing block. The material pushing cylinder is fixedly installed on the extension part on the left side of the lower die. The material pushing block is arranged on the telescopic rod of the material pushing cylinder, and the material pushing block is used to clean the waste on the top of the lower die;

[0009] The material collecting device includes a first slide plate, a linear guide rail and a driving device. The first slide plate is arranged on the slider of the linear guide rail. The driving device is arranged at the bottom end of the linear guide rail. The driving device is used to make the first slide plate reciprocate on the linear guide rail. One end of the linear guide rail is fixedly connected to the workbench, and an aggregate box is arranged at the other end of the linear guide rail.

[0010] By adopting the above technical solutions, the material pushing device uses a material pushing block to push the waste from the workbench. The finished workpiece will be lifted by the upper die. After the upper die stops, the finished workpiece will be pushed down by the ejector pin in the die. At this time, the first slide plate will be moved to the blanking position by the driving device. The first slide plate is inclined. After the finished workpiece falls on the slide plate, it will slide down along the inclined direction towards the aggregate box. During the sliding process, the first slide plate will return to its original position. The material pushing and collecting of the pure mechanical structure are simple and reliable, which can effectively complete the separation of the waste of the stamping parts, and no dust will be generated during the whole process.

[0011] In a further embodiment, a second slide plate is arranged on the top of the workbench. The second slide plate and the material pushing device are oppositely arranged on the top of the workbench. The second slide plate is provided with an extension end located outside the workbench. One end of the second slide plate located on the top of the workbench is fixedly connected to the workbench through a lifting cylinder, and waste boxes are arranged at intervals at the bottom of the extension end.

[0012] By adopting the above technical solutions, in addition to the first slide plate, a second slide plate is also arranged on the side opposite to the material pushing device. After the material pushing block on the cylinder telescopic rod pushes the waste of the stamping part away from its original position, the waste will rush towards the second slide plate. Since the second slide plate is also inclined, the waste will slide all the way along the inclined direction into the waste box.

[0013] In a further embodiment, a limit stop block is fixedly installed on the side of the material pushing cylinder close to the second slide plate. A through hole is arranged on the limit stop block. The telescopic rod of the material pushing cylinder is coaxially arranged with the through hole. The material pushing block is arranged on the side of the limit stop block close to the second slide plate.

[0014] By adopting the above technical solutions, while further fixing the material pushing cylinder, the limit stop block can also limit the material pushing block, so that the material pushing block always keeps close to the surface of the die, avoiding the situation of material pushing failure when pushing some thinner workpieces, thereby effectively improving the yield rate.

[0015] In a further embodiment, a retaining wall is fixedly installed on the peripheral edge of the top of the first slide plate, and one side of the retaining wall close to the aggregate bin is inclined.

[0016] By adopting the above technical solution, the retaining wall can prevent the workpiece from sliding off the first slide plate during the movement of the first slide plate, and the inclined setting of the side close to the aggregate bin facilitates the workpiece to fall from this side.

[0017] In a further embodiment, a safety two-hand control switch is fixedly installed on the side of the workbench opposite to the first slide plate.

[0018] By adopting the above technical solution, since the feeding of the punching machine is a monotonous and repetitive task, it is easy for the operator to be distracted and inattentive during this process. Therefore, the two-hand switch is crucial for the safety of the punching machine.

[0019] In a further embodiment, an emergency stop button is provided on the safety two-hand control switch.

[0020] By adopting the above technical solution, the emergency stop button on the two-hand switch device is arranged between the left button and the right button, ensuring that it is closest to the human body in case of an emergency and can stop the punching machine immediately.

[0021] In summary, the present utility model has the following beneficial effects:

[0022] 1. Through the setting of the material pushing device, it is possible to complete the pushing of the punching part waste on the workbench by relying on the cylinder to drive the material pushing block without using gas blowing. During the pushing process, the limit stop block will also limit the position of the material blocking block, making it always close to the surface of the mold to ensure no gap. Even very thin workpieces can be pushed onto the second slide plate and fall into the waste bin along the inclined second slide plate. The structure is simple and reliable, with a long service life and does not require frequent maintenance, achieving the effect of avoiding dust and protecting the health of the staff;

[0023] 2. Through the setting of the aggregate device, the inclined first slide plate can reciprocate on the linear guide rail. After the punching is completed, the first slide plate moves to the blanking position to wait for the processed workpiece to fall. The falling workpiece slides along the inclined direction of the first slide plate until it falls into the aggregate bin. Before the punching starts, the first slide plate will reset to the initial position to avoid collision with the punching machine. The retaining wall arranged on the periphery of the first slide plate can prevent the workpiece from sliding off the first slide plate during the movement and achieve the effect of safely and effectively falling the workpiece into the aggregate bin;

[0024] 3. Through the setting of the safety two-hand control switch, the operator's hands can be kept away from the stamping machine body when the stamping machine starts by pressing buttons that need to be pressed simultaneously. The emergency stop button in the middle of the switch is simple and intuitive. In case of dangerous accidents or machine failures, the emergency stop button can be pressed immediately to stop the machine and avoid further hazards, achieving the effect of ensuring safe production and protecting the safety of operators.

[0031] Embodiment:

[0032] As Figure 1 - Figure 2As shown in the figure, a stamping waste separation device includes a stamping machine body 1. A mold 2 is provided on the stamping machine body 1. The mold includes an upper mold 21 and a lower mold 22. The lower mold 22 is arranged on the workbench. An extension part is provided on the left side of the lower mold 22. A material pushing device 3 is arranged on the top of the lower mold 22. An aggregate device 4 is arranged on one side of the workbench. The material pushing device 3 includes a material pushing cylinder 31 and a material pushing block 32. The material pushing cylinder 31 is fixedly installed on the extension part on the left side of the lower mold 22. The material pushing block 32 is arranged on the telescopic rod of the material pushing cylinder 31. The material pushing block 32 is used to clean the waste on the top of the lower mold 22. A limit stop block 5 is fixedly installed on one side of the material pushing cylinder 31 close to the second slide plate 33. A through hole is provided on the limit stop block 5. The telescopic rod of the material pushing cylinder 31 is coaxially arranged with the through hole. The material pushing block 32 is arranged on the side of the limit stop block 5 close to the second slide plate 33. A second slide plate 33 is arranged on the top of the workbench. The second slide plate 33 and the material pushing device 3 are oppositely arranged on the top of the workbench. The second slide plate 33 is provided with an extension end located outside the workbench. One end of the second slide plate 33 located on the top of the workbench is fixedly connected to the workbench through a lifting cylinder. Waste bins 34 are arranged at intervals at the bottom of the extension end. The material pushing cylinder 31 can drive the material pushing block 32 to make a reciprocating motion on the surface of the workbench, while the limit stop block 5 can limit the telescopic rod of the material pushing cylinder 31, so that the material pushing block 32 can fit as closely as possible to the surface of the workbench, preventing the thinner waste from passing through the gap between the material pushing block 32 and the workbench after stamping and remaining on the workbench, which affects the quality of the next stamping part. The second slide plate 33 on one side of the workbench can make the waste pushed out by the material pushing block 32 fall along the slide plate into the waste bins 34, so as to carry out the waste recycling work.

[0033] As Figure 1 - Figure 3As shown in the figure, the aggregate device 4 includes a first slide plate 41, a linear guide rail 42 and a driving device 43. The first slide plate 41 is arranged on the slider of the linear guide rail 42, and the driving device 43 is arranged at the bottom end of the linear guide rail 42. The driving device 43 is used to make the first slide plate 41 reciprocate on the linear guide rail 42. One end of the linear guide rail 42 is fixedly connected to the workbench. A safety two-hand control switch 6 is fixedly installed on the side of the workbench opposite to the first slide plate 41. An emergency stop button is arranged on the safety two-hand control switch 6. An aggregate box 44 is arranged at the other end of the linear guide rail 42. A retaining wall is fixedly installed on the peripheral edge of the top of the first slide plate 41. The side of the retaining wall close to the aggregate box 44 is inclined. By fixing the first slide plate 41 on the linear guide rail 42, the first slide plate 41 can reciprocate with the slider on the linear guide rail 42, thus avoiding the collision between the upper die and the first slide plate 41 during the stamping process. After the stamping is completed, the workpiece is ejected from the upper die by the ejector pin in the die 2 and thus falls on the first slide plate 41. Then the first slide plate 41 moves towards the aggregate box 44. During this process, since the first slide plate 41 is inclined, the workpiece will slide into the aggregate box 44. The retaining wall is arranged on the peripheral edge of the top of the first slide plate 41, which can prevent the workpiece from sliding off from both sides during the movement of the first slide plate 41, further improving the stability of the aggregate device 4. The safety two-hand control switch 6 and the emergency stop button can protect the staff and avoid mechanical injuries caused by their non-standard operations.

[0034] Specific implementation process: Place the workpiece to be processed on the lower die. Press the left button and the right button on the safety two-hand control switch 6. The upper die drops and stamps the workpiece. After the stamping is completed, the waste material will be left on the workbench, and the processed workpiece will be left on the upper die due to the pressure during stamping and will be lifted accordingly. At this time, the pushing cylinder 31 in the pushing device 3 operates, and the telescopic rod extends forward to push the pushing block 32 to move. During the movement, since the telescopic rod of the pushing cylinder is arranged in the through hole on the limit stop block 5, the limit stop block 5 will limit the telescopic rod of the pushing cylinder 31, and then the pushing block 32 will always be close to the surface of the workbench, so that some thinner waste materials will not leak through the gap between the pushing block 32 and the work platform and affect the next processing. The pushed waste material will fall on the second slide plate 33 and slide all the way along the inclined second slide plate 33 into the waste box 34. After the upper die rises to the top, the ejector pin inside the die 2 will drop and eject the processed workpiece. At this time, the first slide plate 41 will move with the slider on the linear guide rail 42, so that the processed workpiece will just fall on the first slide plate 41. With the slider moving again, the workpiece on the first slide plate 41 will fall into the aggregate box 44.

[0035] In the embodiments disclosed by the present utility model, terms such as "installation", "connection", "attachment", "fixation", etc. shall be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments disclosed by the present utility model may be understood according to specific circumstances.

[0036] This specific embodiment is only an interpretation of the present utility model and does not limit the present utility model. After reading this specification, those skilled in the art may make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
