Description

Technical Field

[0001] This utility model relates to the field of precision machining technology for hardware parts, specifically a punching machine for machining hardware parts. Background Technology

[0002] Hardware refers to tools or parts made of metal materials, including locks, handles, door and window accessories, etc. They are widely used in building decoration, home equipment and industrial production. In the processing of hardware, punching equipment is used frequently to perform stamping processing on hardware.

[0003] In the prior art, the patent publication number CN 221581838 U proposes a punching machine for processing hardware parts. Although it can perform stamping processing of hardware parts, after processing, in order to avoid the influence of dust and debris on the surface of the processing platform on subsequent processing, it is necessary to frequently clean the surface of the processing platform. Due to the horizontal installation of the processing platform of most stamping equipment, it is inconvenient to remove dust and debris from the platform surface during cleaning, which affects the cleaning efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a punching machine for processing hardware parts. By pushing the movable plate to slide and rotate in the slide groove, the movable plate is in an inclined state during the cleaning process, which facilitates the removal of dust or debris from the surface of the movable plate. This makes the cleaning of the worktable of the punching machine faster and more convenient, improves the efficiency of hardware parts processing, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching machine for processing hardware parts, including a punching machine housing, a processing platform at the front end of the punching machine housing, and a movable platform mechanism; The movable platform mechanism includes a slide groove, a limiting slide groove, a movable plate, and a sliding column. The slide groove is set on the upper surface of the processing platform. The slide groove is an L-shaped groove. The front and rear inner walls of the slide groove are provided with limiting slide grooves. The movable plate is slidably connected inside the slide groove. The middle of the front and rear sides of the movable plate is provided with a sliding column, which is slidably connected to the adjacent limiting slide groove in the lateral direction.

[0006] Furthermore, the movable platform mechanism also includes a limiting insertion hole, a limiting bolt, and a screw hole. The screw hole is located at the right end of the front surface of the processing platform and is connected to the right end of the limiting slide groove. The screw hole is internally threaded with a limiting bolt. The limiting insertion hole is located at the right end of the front surface of the movable plate and is installed in conjunction with the limiting bolt to restrict the left and right movement of the movable plate.

[0007] Furthermore, an external hexagonal column is longitudinally slidably connected in the internal hexagonal groove on the rear side of the limiting bolt, and the front surface of the sliding column is provided with an internal hexagonal socket that mates with the external hexagonal column to limit the tilt angle of the movable plate.

[0008] Furthermore, the outer hexagonal column is provided with a ring on its outer side, and a spring is provided between the ring and the limiting bolt. The spring is movably sleeved on the outer arc surface of the inner hexagonal tube at the right end of the limiting bolt, which facilitates the insertion of the outer hexagonal column and the inner hexagonal socket.

[0009] Furthermore, each of the outer arc surfaces of the sliding column is rotatably connected to a rectangular block, which is laterally slidably connected to the interior of an adjacent limiting groove. Each of the outer arc surfaces of the sliding column is movably fitted with a torsion spring. The end of the torsion spring near the movable plate is fixedly connected to the rectangular block, and the end of the torsion spring away from the movable plate is fixedly connected to the limiting plate at the end of the sliding column, providing resistance to the rotation of the movable plate and making the rotation of the movable plate more stable.

[0010] Furthermore, buffers are provided in the mounting holes on the bottom wall of the chute, and the buffers are installed in conjunction with the left end of the movable plate to reduce the impact of the movable plate resetting on the processing platform.

[0011] Furthermore, the limiting slide is an L-shaped groove, and the upper end of the vertical groove at the left end of the limiting slide is an open structure. A stop block is fixedly connected inside the vertical groove of the limiting slide to provide space for the disassembly of the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By pushing the movable plate to slide and rotate within the chute, the movable plate is tilted during the cleaning process. Compared to cleaning the worktable surface in a horizontal state, this makes it easier for dust or debris to detach from the surface of the movable plate, making the cleaning of the punch press worktable faster and more convenient, and improving the efficiency of hardware processing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This embodiment provides a technical solution: a punching machine for processing hardware parts, including a punching machine housing 1. The punching machine housing 1 adopts a punching machine commonly used in the prior art, including a transmission system, a power system, and a control system. The transmission system includes components such as a flywheel, clutch, gears, crankshaft, and connecting rod to realize the conversion of circular motion to linear motion. The power system is usually driven by an electric motor, which transmits power to the flywheel through a belt or gear, and then controls the punching action through the clutch. The control system can be a PLC controller, which is set at the front end of the punching machine housing 1 to control the start and stop of the entire device. The front end of the punching machine housing 1 is provided with a processing platform 2 to provide support for the stamping processing of hardware parts.

[0017] The system also includes a movable platform mechanism 3. The movable platform mechanism 3 includes a slide 31, a limiting slide 32, a movable plate 33, and a sliding column 34. The slide 31 is located on the upper surface of the processing platform 2. The slide 31 is an L-shaped groove. The right end of the horizontal groove of the slide 31 is connected to the upper end of the vertical groove. The front and rear inner walls of the slide 31 are provided with limiting slides 32. The movable plate 33 is slidably connected inside the slide 31. The middle of the front and rear sides of the movable plate 33 is provided with sliding columns 34, which are slidably connected to the adjacent limiting slides 32. The movable platform mechanism 3 also includes a limiting insertion hole 35, a limiting bolt 36, and a screw hole 37. The screw hole 37 is located on the right end of the front surface of the processing platform 2. The screw hole 37 is connected to the right end of the limiting slide 32. The screw hole 37 is threadedly connected to the internal thread of the screw hole 37. The limiting insertion hole 35 is located on the right end of the front surface of the movable plate 33. The limiting insertion hole 35 and the limiting bolt 36 are installed together.

[0018] Among them, an external hexagonal column 4 is longitudinally slidably connected in the internal hexagonal groove on the rear side of the limiting bolt 36. The front surface of the sliding column 34 is provided with an internal hexagonal socket 5 that mates with the external hexagonal column 4. When the movable plate 33 is in the maximum rightward position, the external hexagonal column 4 and the internal hexagonal socket 5 are longitudinally aligned. The tilt angle of the movable plate 33 is limited by the insertion of the external hexagonal column 4 and the internal hexagonal socket 5.

[0019] Among them, the outer hexagonal column 4 is provided with a ring 6 on its outer side, and a spring 7 is provided between the ring 6 and the limiting bolt 36. The spring 7 is movably sleeved on the outer arc surface of the inner hexagonal tube at the right end of the limiting bolt 36. The limiting bolt 36 is rotated periodically to pull the limiting bolt 36 out of the screw hole 37, so that the spring 7 can be replaced or maintained to ensure the normal use of the spring 7.

[0020] The outer arc surface of the sliding column 34 is rotatably connected to a rectangular block 8. The rectangular block 8 is slidably connected to the interior of the adjacent limiting slide groove 32. The outer arc surface of the sliding column 34 is movably fitted with a torsion spring 9. The end of the torsion spring 9 near the movable plate 33 is fixedly connected to the rectangular block 8, and the end of the torsion spring 9 away from the movable plate 33 is fixedly connected to the limiting plate at the end of the sliding column 34.

[0021] The slide 31 has a buffer 10 installed in the mounting hole in the bottom wall of the horizontal groove. The buffer 10 is installed in conjunction with the left end of the movable plate 33. The buffer 10 can be a hydraulic buffer to reduce the impact force on the processing platform 2 when the movable plate 33 rotates counterclockwise to reset. The limiting slide 32 is an L-shaped groove. The left end of the horizontal groove of the limiting slide 32 is connected to the lower end of the vertical groove. The upper end of the vertical groove at the left end of the limiting slide 32 is an open structure. A stop block 11 is fixedly connected inside the vertical groove of the limiting slide 32. The bolts on the surface of the stop block 11 are rotated periodically to remove the stop block 11 from the vertical groove of the limiting slide 32, providing space for the rectangular block 8 to leave the limiting slide 32. The torsion spring 9 is replaced or maintained to ensure its normal use.

[0022] The working principle of this utility model is as follows: In use, the stamping fixed die is fixed on the surface of the movable plate 33, and the stamping moving die is fixed on the punch at the upper end of the punch press housing 1. The rotational motion of the motor is converted into the linear motion of the punch through the transmission system. The die applies pressure to the hardware parts to realize the stamping process of the hardware parts. After stamping is completed, the limit bolt 36 can be rotated. Through the threaded connection between the limit bolt 36 and the screw hole 37, the limit bolt 36 drives the external hexagonal column 4 to move forward. The external hexagonal column 4 is pulled out from the limit insertion hole 35, thus canceling the left and right movement of the movable plate 33. At this time, the movable plate 33 can be pushed to slide in the horizontal groove of the slide 31, and the sliding column 34 drives the rectangular block 8 to slide in the limiting slide 32. When the rectangular block 8 contacts the inner wall on the right side of the horizontal groove of the limiting slide 32, the rectangular block 8 cannot continue to move. At this time, the sliding column 34 enters the vertical groove of the slide 31, providing clearance space for the clockwise rotation of the movable plate 33. Then, push the movable plate 33 to rotate clockwise to overcome the torque of the torsion spring 9, so that the sliding column 34 and the rectangular block 8 rotate relative to each other. Under the action of the torque of the torsion spring 9, it provides counterclockwise resistance for the rotation of the movable plate 33, making the rotation of the movable plate 33 more stable. At this time, the internal hexagon socket 5 and the external hexagon column 4 are in the longitudinal position corresponding. When the movable plate 33 is rotated to the required angle, the limit bolt 36 is rotated in the opposite direction, causing the limit bolt 36 to drive the external hexagonal column 4 to move backward. When the external hexagonal column 4 does not coincide with the internal hexagonal socket 5, as the external hexagonal column 4 moves backward, after the external hexagonal column 4 contacts the sliding column 34, it will overcome the elastic force of the spring 7, causing the external hexagonal column 4 to slide longitudinally in the internal hexagonal groove of the limit bolt 36. At the same time, the personnel can adjust the angle of the movable plate 33 back and forth. When the external hexagonal column 4 and the internal hexagonal socket 5 are longitudinally aligned, the external hexagonal column 4 is directly inserted into the internal hexagonal socket 5 under the elastic force of the spring 7, which restricts the angle of the movable plate 33 and keeps the movable plate 33 in an inclined state, making it convenient to clean the debris or dust generated on the surface of the movable plate 33 due to processing. After cleaning, repeat the above operation in reverse to restore the movable plate 33 to its initial state. The left and right positions of the movable plate 33 are restricted by the insertion of the external hexagonal post 4 into the limiting socket 35.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
