Technical Field
[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a small punch press for processing terminal blocks. Background Technology
[0002] Terminal blocks, as key components in electrical connections, are widely used in various electrical equipment and automation control fields. Their processing typically involves multiple steps such as stamping, punching, and bending. Small punch presses, due to their small size and flexible operation, are frequently used in the small-scale production and precision machining of terminal blocks.
[0003] However, existing small punch presses for terminal block processing have many shortcomings. The feeding and positioning mechanisms are not precise enough, and manual feeding is not only labor-intensive but also makes it difficult to ensure the consistency of the feeding position, resulting in large deviations in the dimensions of the processed terminal blocks. This affects the stamping dimensions of the terminal blocks and thus the processing efficiency. To address these issues, a small punch press for terminal block processing is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a small punch press for processing terminal blocks, so as to solve the problems mentioned in the background art.
[0005] To solve the above problems, the following technical solution is provided: a small punch press for processing terminal blocks, including a frame, a worktable fixedly installed on the upper end of the frame, and a PLC controller fixedly installed on the outer wall of the worktable. An adjustment structure is provided above the worktable, the adjustment structure including a limit frame fixedly installed on the upper end of the worktable, a drive motor fixedly installed inside the limit frame, and a bidirectional lead screw fixedly connected to the output end of the drive motor. Two connecting cylinders are symmetrically threaded to the outer wall of the bidirectional lead screw, and a support plate is fixedly installed on the upper end of each connecting cylinder. Two positioning plates are symmetrically arranged on the upper end of the support plates, and an electric push rod is fixedly installed inside each of the two positioning plates. An anti-slip clamp is fixedly connected to one end of the electric push rod. A mounting frame is fixedly installed above the limit frame at the lower end of the frame, and stamping structures are provided at both ends of the mounting frame.
[0006] As a preferred embodiment of the above technical solution, the bidirectional lead screw is rotatably installed inside the limiting frame, and guide sliders are symmetrically arranged at the bottom of the two support plates and the guide sliders are slidably connected to the guide rails. Both guide rails are fixedly installed on the upper part of the worktable.
[0007] As a preferred embodiment of the above technical solution, a placement frame is fixedly provided on the upper end of the support plate, and a wiring terminal is placed on the upper end of the placement frame, wherein the wiring terminal is adapted to the position of the placement frame.
[0008] As a preferred embodiment of the above technical solution, the two sets of positioning plates are symmetrically connected to the electric push rod with limiting slide rods inside, and one end of the limiting slide rod is fixedly connected to the anti-slip clamp. The two sets of anti-slip clamps are positioned opposite to the two sides of the wiring terminal.
[0009] As a preferred embodiment of the above technical solution, the stamping structure includes two limiting plates fixedly installed at the bottom of the mounting frame, and a positioning frame is fixedly installed on the upper end of each of the two limiting plates. A stamping cylinder is fixedly installed on the upper end of each positioning frame, and a support base is fixedly connected to one end of each stamping cylinder.
[0010] As a preferred embodiment of the above technical solution, a linear slider is fixedly installed on the outer wall of the support base, and the outer wall of the linear slider is slidably connected to the inside of the linear slide rail. The linear slide rail is fixedly installed on the inner wall of the positioning frame. A guide plate is fixedly installed on the outer wall of the positioning frame below the linear slide rail. A stamping rod is fixedly installed at the bottom of the support base, and a buffer spring is sleeved on the outer wall of the stamping rod. A stamping die is fixedly connected to one end of the stamping rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device is equipped with an adjustment structure. By driving the electric push rods in the two positioning plates on the drive support plate to work synchronously, the electric push rods drive the anti-slip clamping plates to clamp and position the two sides of the terminal block. Then, the drive motor in the drive limit frame drives the bidirectional lead screw to rotate, causing the bidirectional lead screw to move the support plates on the two connecting cylinders to move relative to each other directly below the stamping die. This facilitates stable and accurate positioning and feeding of the terminal block while performing dual-station stamping operations, reducing the workload of the workers, ensuring consistent feeding, and improving the stamping efficiency of the terminal block.
[0012] 2. The device of this utility model is equipped with a stamping structure. By driving the stamping cylinders on the two positioning frames, the support base moves. When the support base moves downward, it uses a linear slider to slide on a linear slide rail, which makes the support base stably drive the stamping die on the stamping rod to process and stamp the terminal. At the same time, when the support base presses down, it squeezes the buffer spring to compress and deform, which is beneficial to the precise stamping of the terminal while improving the buffer protection of the stamping die and extending its service life.

It should be understood that the embodiments of the present invention are not limited in scope.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1 to 5 As shown in the figure, this embodiment provides a small punch press for processing terminal blocks, including a frame 1. A worktable 4 is fixedly installed on the upper end of the frame 1, and a PLC controller 6 is fixedly installed on the outer wall of the worktable 4. An adjustment structure 5 is provided above the worktable 4. The adjustment structure 5 includes a limit frame 51 fixedly installed on the upper end of the worktable 4. A drive motor 52 is fixedly installed inside the limit frame 51, and a bidirectional lead screw 53 is fixedly connected to the output end of the drive motor 52. Two connecting cylinders 56 are symmetrically threaded to the outer wall of the bidirectional lead screw 53, and a support plate 57 is fixedly installed on the upper end of each connecting cylinder 56. Two positioning plates 58 are symmetrically arranged on the upper end of the support plate 57. An electric push rod 581 is fixedly installed inside each of the two positioning plates 58, and an anti-slip clamp 583 is fixedly connected to one end of the electric push rod 581. A mounting frame 2 is fixedly installed above the limit frame 51 at the lower end of the frame 1, and a stamping structure 3 is provided at both ends of the mounting frame 2.
[0018] like Figures 3 to 4 As shown, the bidirectional lead screw 53 is rotatably installed inside the limiting frame 51. The bottom of the two support plates 57 is symmetrically provided with guide sliders 55, and the guide sliders 55 are slidably connected to the guide rails 54. The two guide rails 54 are fixedly installed on the upper end of the worktable 4. The upper end of the support plate 57 is fixedly provided with a placement frame 59, and the upper end of the placement frame 59 is provided with a terminal block. The terminal block is matched with the position of the placement frame 59. The two sets of positioning plates 58 are symmetrically slidably connected to the electric push rod 581 with limiting slide rods 582 inside. One end of the limiting slide rod 582 is fixedly connected to the anti-slip clamp 583. The two sets of anti-slip clamps 583 are opposite to the two sides of the terminal block.
[0019] The two connecting cylinders 56 are moved relative to each other by the bidirectional lead screw 53. The support plates 57 are slidably engaged with the guide sliders 55 on both sides of the bottom along the guide rail 54, so that the two support plates 57 can move the terminal blocks relatively stably. At the same time, two limit sliders 582 are set in the positioning plate 58 to make the anti-slip clamping plate 583 relatively stable when clamping the terminal blocks. The PLC controller 6 is electrically connected to the stamping cylinder 33, the drive motor 52 and the electric push rod 581 respectively, receives signals and issues control commands to realize the automated operation and precise control of the punch press. At the same time, a positioning sensor is set at the upper end of the frame 1 below the mounting frame 2, which can accurately detect the position of the raw material and transmit the position information to the control module. The precision support plate 57 is translated by the drive motor 52. The above are existing mature technologies and have not been described in detail in this application.
[0020] like Figure 5 As shown, the stamping structure 3 includes two limiting plates 31 fixedly installed at the bottom of the mounting frame 2, and a positioning frame 32 is fixedly installed on the upper end of each of the two limiting plates 31. A stamping cylinder 33 is fixedly installed on the upper end of each positioning frame 32, and a support base 36 is fixedly connected to one end of the stamping cylinder 33. A linear slider 35 is fixedly installed on the outer wall of the support base 36, and the outer wall of the linear slider 35 is slidably connected to the inside of the linear slide rail 34. The linear slide rail 34 is fixedly installed on the inner wall of the positioning frame 32. A guide plate is fixedly provided on the outer wall of the positioning frame 32 below the linear slide rail 34. A stamping rod is fixedly provided at the bottom of the support base 36, and a buffer spring 37 is sleeved on the outer wall of the stamping rod. A stamping die 38 is fixedly connected to one end of the stamping rod.
[0021] The stamping cylinder 33 drives the support base 36 to slide along the linear slider 35 on the linear slide rail 34, thereby making the stamping rod drive the stamping die 38 to move downwards and making the terminal processing relatively stable. At the same time, a buffer spring 37 is sleeved on the outside of the stamping rod to facilitate buffer protection when the stamping die 38 is stamped again.
[0022] The working principle and process of this utility model are as follows: Before processing, the terminals to be processed are placed on the placement rack 59 according to their specifications and process requirements. Then, the external power supply is connected, and the electric push rods 581 in the two positioning plates 58 on the drive support plate 57 work synchronously, causing the electric push rods 581 to drive the anti-slip clamping plates 583 to clamp and position the terminals on both sides. After the terminals are positioned, the drive motor 52 in the drive limit frame 51 drives the bidirectional lead screw 53 to rotate, causing the bidirectional lead screw 53 to drive the support plates 57 on the two connecting cylinders 56 synchronously. The relative movement to both sides of the mounting bracket 2 enables stable and precise feeding of the terminal block while performing dual-station processing. After the raw material reaches the stamping position, the stamping cylinders 33 on the two positioning brackets 32 drive the support base 36 to move. When the support base 36 moves downward, it uses the linear slider 35 to slide on the linear slide rail 34, which causes the support base 36 to stably drive the stamping die 38 on the stamping rod to perform stamping operation on the terminal block. At the same time, when the support base 36 presses down, it squeezes the buffer spring 37 to compress and deform, thereby buffering and protecting it.
