Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching and cutting device for machining mechanical parts. Background Art

[0002] Mechanical parts are the basic components of machinery and are also the inseparable individual parts that make up machinery and machines. It is not only a discipline for studying and designing the basic mechanical parts of various equipment, but also a general term for parts and components.

[0003] Stamping is mainly a metal processing method that uses a mold to apply pressure to metal sheets on a press to separate or plastically deform them, thereby obtaining a workpiece of the desired shape and size. In the production process of mechanical parts, when the parts need to be stamped to form a specific shape or structure, a stamping process is required.

[0004] In the prior art, the stamping process of mechanical parts generally relies on manual placement of plates, and then the stamping equipment applies downward pressure to cut out the required shape. This traditional method is not only inefficient because it requires frequent manual feeding, but also has safety hazards that cannot be ignored. In addition, with the continuous development of automation technology, although automated equipment has been introduced to convey plates for stamping operations, the stamping process must coordinate the conveying time cycle, and the equipment must be controlled to stop conveying during stamping, and the control system is relatively complex. In addition, during the stamping process, if huge pressure acts directly on the conveying structure, it is very easy to cause structural damage, thereby seriously affecting the stability and service life of the equipment, and it is urgent to improve. Utility Model Content

[0005] The purpose of the utility model is to provide a punching and cutting device for machining mechanical parts to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A punching and cutting device for machining mechanical parts comprises a frame, on which an operating platform located in the center and a double-layer structure of a top plate located at the top are arranged, a plurality of columns are fixedly connected between the operating platform and the top plate; a hydraulic cylinder is fixedly installed on the frame at the top of the top plate, a piston rod of the hydraulic cylinder extends to the bottom of the top plate and is fixedly connected to a lifting frame, a plurality of punching heads are fixedly connected to the bottom of the lifting frame, a receiving groove is provided on the frame at the top of the operating platform, a liftable conveying component is arranged inside the receiving groove, and the conveying component is used to convey plates; a plurality of die holes are also provided on the frame at the top of the operating platform.

[0008] By adopting the above technical solution, a liftable conveying component is provided, and then the conveying component can be controlled to descend when stamping is required. On the one hand, the stamping process no longer requires continuous feeding, thereby facilitating operation. On the other hand, it avoids direct pressure on the conveying component, thereby greatly improving the service life of the device.

[0009] A further improvement of the technical solution of the utility model is that: a plurality of support rods are slidably connected to the bottom of the inner wall of the accommodating groove, the top of the support rod is fixedly connected to the conveying component, the bottom of the support rod extends to the bottom of the frame and is fixedly connected to a linkage plate, the two sides of the linkage plate are symmetrically fixedly connected to connecting plates, the bottom of the frame is slidably connected to a linkage rod, the bottom of the linkage rod is fixedly connected to the linkage plate, and the top of the linkage rod extends to the top of the operating platform and is fixedly connected to the lifting frame.

[0010] By adopting the above technical solution, the lifting frame moves downward, and drives the connecting plate and the linkage plate to move downward through the linkage rod. The movement of the linkage plate will drive the support rod to move, and then the conveying component moves downward until the top of the conveying component is lower than the bottom height of the inner wall of the groove, so that the plate is supported by the groove, and the conveying component is out of contact with the plate. At this time, no feeding is carried out, which facilitates the stamping operation.

[0011] A further improvement of the technical solution of the utility model is that: two cross bars are symmetrically fixedly connected between the inner sides of the frames, a gear is rotatably connected between the sides of the two cross bars that are close to each other, a rack is fixedly connected to one side of the linkage plate, the rack is meshed with the gear, one side of the gear is connected to two annular plates by screws, the two annular plates are combined into a circular ring, the top of one of the cross bars is connected to a U-shaped plate by screws, one side of the U-shaped plate is slidably connected to a resist column, one end of the resist column extends to the inner side of the U-shaped plate and is fixedly connected to a pad, the other side of the U-shaped plate is slidably connected to a sliding rod, one end of the sliding rod extends to the inner side of the U-shaped plate and is fixedly connected to the pad, a tightening spring is sleeved on the outer side of the sliding rod, the end of the resist column away from the pad contacts with one side of the annular plate, and the side of the annular plate in contact with the resist column is set to a rough surface.

[0012] By adopting the above technical solution, during the movement of the linkage plate, the rack will be driven to move downward, thereby causing the gear to rotate and the annular plate and the support column to slide relative to each other, thereby causing the device to vibrate slightly to assist the cut parts to fall downward to avoid jamming.

[0013] A further improvement of the technical solution of the utility model is that: a plurality of feeding holes communicating with the inside of the die hole are opened at the bottom of the frame, and the diameter of the feeding holes is slightly larger than the die hole.

[0014] When adopting the above technical solution, the operating platform of the frame must have a certain thickness because it needs to bear pressure. Two holes are set to penetrate the platform, and the diameter of the feed hole is slightly larger than the die hole to avoid material jamming due to the die hole being too thick.

[0015] A further improvement of the technical solution of the utility model is that a discharging rack is fixedly connected to the bottom of the frame.

[0016] The above technical solution makes it easy for the cut parts to fall downward to the discharge rack, and a receiving frame is placed under the discharge rack to receive the parts.

[0017] A further improvement of the technical solution of the utility model is that the lifting frame is slidably connected to two of the uprights.

[0018] By adopting the above technical solution, the upright column can be used as a guide rod for the sliding of the lifting frame, so that the movement of the lifting frame is more stable.

[0019] A further improvement of the technical solution of the utility model is that a controller is fixedly connected to one side of the frame, and the hydraulic cylinder and the driving uniform controller in the conveying component are electrically connected.

[0020] By adopting the above technical solution, it is convenient to control the operation of the hydraulic cylinder and the conveying components through the controller.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a punching and cutting device for machining mechanical parts. By setting a liftable conveying component, the conveying component can be controlled to descend when punching is required. On the one hand, the punching process no longer requires continuous feeding, thereby facilitating operation. On the other hand, direct pressure on the conveying component is avoided, thereby greatly improving the service life of the device and facilitating practical application.

[0023] 2. The utility model provides a stamping and cutting device for machining mechanical parts. By setting a linkage rod, the stamping process can drive the connecting plate and the linkage plate to move downward through transmission. The movement of the linkage plate will drive the support rod to move, and then the conveying component will move downward until the top of the conveying component is lower than the bottom height of the inner wall of the groove, so that the plate is supported by the groove, and the conveying component is out of contact with the plate, so there is no need for a special control system and execution drive, which greatly saves the implementation cost.

[0024] 3. The utility model provides a punching and cutting device for machining mechanical parts. By setting an annular plate with a rough surface, the rack is driven to move downward during the movement of the linkage plate, thereby causing the gear to rotate and the annular plate and the support column to slide relative to each other, thereby causing the device to vibrate slightly to assist the cut parts to fall downward to avoid material jamming.

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1-Figure 6 As shown, the utility model provides a punching and cutting device for machining mechanical parts, including a frame 1, on which an operating platform located in a central position and a double-layer structure of a top plate located at the top are provided, and a plurality of columns are fixedly connected between the operating platform and the top plate; the frame 1 is fixedly installed with a hydraulic cylinder 2 on the top of the top plate, the piston rod of the hydraulic cylinder 2 extends to the bottom of the top plate and is fixedly connected with a lifting frame 3, and a plurality of punching heads 4 are fixedly connected to the bottom of the lifting frame 3, a receiving groove 5 is provided on the top of the operating platform of the frame 1, and a liftable conveying component 6 is provided inside the receiving groove 5, and the conveying component 6 is used to convey the plate; the frame 1 is also provided with a plurality of die holes 11 on the top of the operating platform.

[0036] In this embodiment, a liftable conveying component 6 is provided, so that when stamping is required, the conveying component 6 can be controlled to descend. On the one hand, the stamping process no longer requires continuous feeding, thereby facilitating operation. On the other hand, direct pressure on the conveying component 6 is avoided, thereby greatly improving the service life of the device and facilitating practical applications.

[0037] like Figure 3 and Figure 6 As shown, preferably, a plurality of support rods 10 are slidably connected to the bottom of the inner wall of the accommodating groove 5, the top of the support rod 10 is fixedly connected to the conveying component 6, the bottom of the support rod 10 extends to the bottom of the frame 1 and is fixedly connected to a linkage plate 9, the two sides of the linkage plate 9 are symmetrically fixedly connected to connecting plates 8, the bottom of the frame 1 is slidably connected to a linkage rod 7, the bottom of the linkage rod 7 is fixedly connected to the linkage plate 9, and the top of the linkage rod 7 extends to the top of the operating platform and is fixedly connected to the lifting frame 3.

[0038] In this embodiment, the lifting frame 3 moves downward, and drives the connecting plate 8 and the linkage plate 9 to move downward through the linkage rod 7. The movement of the linkage plate 9 drives the support rod 10 to move, thereby causing the conveying component 6 to move downward until the top of the conveying component 6 is lower than the bottom height of the inner wall of the groove, so that the plate is supported by the groove, and the conveying component 6 is out of contact with the plate. At this time, no feeding is performed, thereby facilitating the stamping operation.

[0039] like Figure 1 and Figure 2 As shown, preferably, a controller is fixedly connected to one side of the frame 1, and the hydraulic cylinder 2 and the driving controller in the conveying component 6 are electrically connected.

[0040] In this embodiment, it is convenient to control the operation of the hydraulic cylinder 2 and the conveying component 6 through a controller.

[0041] Example 2

[0042] like Figure 2 and Figure 3As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, two cross bars 14 are symmetrically fixedly connected between the inner sides of the frame 1, a gear 15 is rotatably connected between the two sides of the two cross bars 14 that are close to each other, a rack 16 is fixedly connected to one side of the linkage plate 9, the rack 16 is meshed with the gear 15, one side of the gear 15 is connected to two annular plates 17 by screws, the two annular plates 17 are combined into a circular ring, and the top of one of the cross bars 14 is connected to a U-shaped Plate 18, one side of the U-shaped plate 18 is slidably connected with a support column 21, one end of the support column 21 extends to the inner side of the U-shaped plate 18 and is fixedly connected to a pad 20, the other side of the U-shaped plate 18 is slidably connected with a slide rod 19, one end of the slide rod 19 extends to the inner side of the U-shaped plate 18 and is fixedly connected to the pad 20, a locking spring 22 is sleeved on the outer side of the slide rod 19, one end of the support column 21 away from the pad 20 contacts one side of the annular plate 17, and the side of the annular plate 17 in contact with the support column 21 is set to a rough surface.

[0043] In this embodiment, during the movement of the linkage plate 9, the rack 16 is driven to move downward, thereby causing the gear 15 to rotate and the annular plate 17 and the support column 21 to slide relative to each other, thereby causing the device to vibrate slightly to assist the cut parts to fall downward to avoid jamming.

[0044] like Figure 6 As shown, preferably, a plurality of feed holes 12 communicating with the inside of the die hole 11 are opened at the bottom of the frame 1 , and the diameter of the feed holes 12 is slightly larger than the die hole 11 .

[0045] In this embodiment, due to the need to bear pressure, the operating platform of the frame 1 must have a certain thickness. Two holes are set to penetrate the platform, and the diameter of the feed hole 12 is slightly larger than the die hole 11 to avoid material jamming due to the die hole 11 being too thick.

[0046] like Figure 2 and Figure 3 As shown, preferably, a discharging rack 13 is fixedly connected to the bottom of the frame 1 .

[0047] In this embodiment, in order to facilitate the cut parts to fall downward to the discharge rack 13, a receiving frame is placed under the discharge rack 13 to receive the parts.

[0048] Example 3

[0049] like Figure 1 and Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, the lifting frame 3 is slidably connected to two of the columns.

[0050] In this embodiment, the upright column can be used as a guide rod for the lifting frame 3 to slide, so that the lifting frame 3 can move more stably.

[0051] The working principle of the punching and cutting device for machining mechanical parts will be described in detail below.

[0052] like Figure 1-Figure 6 As shown, the sheet is placed in the groove at the top of the frame 1. When not punched, the sheet is at the top of the conveying component 6. Feeding can be started by controlling the conveying component 6. When the sheet is delivered to the bottom of the punching head 4, the hydraulic cylinder 2 is controlled to work to push the lifting frame 3 to move downward, thereby driving the punching head 4 to move downward on the one hand, and on the other hand, the connecting plate 8 and the linkage plate 9 are driven downward by the linkage rod 7. The movement of the linkage plate 9 will drive the support rod 10 to move, thereby causing the conveying component 6 to move downward until the top of the conveying component 6 is lower than the bottom height of the inner wall of the groove, so that the sheet is supported by the groove, and the conveying component 6 is out of contact with the sheet, and feeding is not performed at this time; and the lifting frame 3 continues to descend, so that the punching head 4 contacts and cuts the sheet, and the punching head 4 pushes the cut sheet into the die hole 11, and falls downward under the action of gravity, passes through the discharge hole 12, and falls into the discharge rack 13, completing the punching and cutting.

[0053] After the stamping is completed, the hydraulic cylinder 2 is controlled to retract, so that the lifting frame 3 is reset, and the punching head 4 is reset, and the linkage plate 9 is reset at the same time, so that the conveying component 6 moves upward until the plate is lifted up. At this time, the conveying component 6 continues to convey the plate.

[0054] During the movement of the linkage plate 9, the rack 16 is driven to move downward, thereby rotating the gear 15 and causing the annular plate 17 and the support column 21 to slide relative to each other, thereby causing the device to vibrate slightly to assist the cut parts to fall downward to avoid jamming.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
