Description

Technical Field

[0001] The utility model relates to the field of steel production and processing, in particular to a positioning mechanism of a punch loading device. Background Art

[0002] With the development of production and operations, the increasing variety of automotive stamping parts, the increasing complexity of processes, and the increasing demand for user-friendly production, punch presses are frequently used in the production of components such as contacts for small circuit breakers to stamp rolled raw materials into the desired finished product shape. The loading device is a mechanical device that automatically or semi-automatically transports the raw material to the punch press's work area. To improve the stability of the raw material (for example, copper), limit plates are installed on both sides of the copper material to prevent its horizontal movement. Specifically, a bidirectional lead screw is rotatably mounted on the machine frame. A handwheel is fixed to one side of the lead screw to control its rotation. Two limit plates are threaded onto different threaded sections of the lead screw. The loading device also includes an extrusion assembly for leveling the copper material. A fixed rod is located at the inlet of the extrusion assembly, and two positioning blocks are mounted on the fixed rod. The two positioning blocks are located on either side of the copper material to control its horizontal position as it enters the extrusion assembly.

[0003] In the prior art, after the steel is loaded, it needs to be extruded using an extrusion roller. However, before extrusion, both sides of the steel are not cleaned, resulting in impurities attached to the steel. During extrusion, the surface of the steel is damaged, affecting the quality of the steel. Therefore, a positioning mechanism for a punch loading device is now proposed. Utility Model Content

The two limit blocks are fixedly connected to a protruding plate, and the ends of the two protruding plates that are close to each other are fixedly connected to a positioning block, and the two positioning blocks cooperate with each other.

[0015] By adopting the above technical solution, since the threads of the two limit blocks are in opposite directions to the threads at both ends of the second bidirectional screw rod, the second bidirectional screw rod drives the two limit blocks to move away from or closer to each other.

The setting of the hand wheel 12 is used to facilitate the staff to drive the first bidirectional screw rod 11. Two screw sleeves 13 are symmetrically connected to the first bidirectional screw rod 11 through threads. Since the thread directions at both ends of the first bidirectional screw rod 11 are respectively opposite to the thread directions of the two screw sleeves 13, the first bidirectional screw rod 11 can drive the two screw sleeves 13 to move closer to or away from each other, and the two screw sleeves The outer wall of 13 is fixedly connected with a limit plate 14, and one side of the two limit plates 14 is slidably connected to the inner wall of the loading seat 1. The two screw sleeves 13 can drive the two limit plates 14 to move away from or approach each other. A second bidirectional screw rod 15 is rotatably connected between the two extended support plates 4, and one end of the first bidirectional screw rod 11 and the second bidirectional screw rod 15 are fixedly connected with a transmission wheel 16, and a transmission belt 17 is connected between the two transmission wheels 16. Since the transmission belt 17 is transmitted between the two transmission wheels 16, the first bidirectional screw rod 11 and the second bidirectional screw rod 15 rotate synchronously.

[0034] Reference Figure 1-3 A positioning assembly is provided between the two extended support plates 4, and the positioning assembly includes two limit blocks 18 that are both slidably connected to one side of the loading seat 1, and the two limit blocks 18 are respectively threadedly connected to the two ends of the second bidirectional screw rod 15, and the two limit blocks 18 are fixedly connected to a protruding plate 19, and the ends of the two protruding plates 19 that are close to each other are fixedly connected to a positioning block 20. When the two positioning blocks 20 are close to each other, the two sides of the steel can be limited. The two positioning blocks 20 cooperate with each other. Since the reverse directions of the threads of the two limit blocks 18 are respectively opposite to the thread directions at both ends of the second bidirectional screw rod 15, the second bidirectional screw rod 15 drives the two limit blocks 18 to move away from or approach each other.

The two extended support plates 4 can ensure that the rotating rod 26 can rotate stably, and one end of the rotating rod 26 is fixedly connected to the second gear 27, and the first gear 25 is meshed with the second gear 27. The meshing between the first gear 25 and the second gear 27 is utilized to make the rotating rod 1 22 and the rotating rod 2 26 rotate synchronously. A brush roller 28 is fixedly connected to the rotating rod 1 22 and the rotating rod 2 26. The two brush rollers 28 cooperate with each other. When the rotating rod 1 22 and the rotating rod 2 26 rotate synchronously, the two brush rollers 28 can rotate to clean the dust and impurities on both sides of the steel.

[0037] The implementation principle of the present utility model is as follows: first, the steel is rolled between the two limit plates 14 in the loading seat 1, one end of the steel is stretched and sequentially passes through the two positioning blocks 20, two brush rollers 28, multiple squeezing rollers 5 and the guide roller 1 7, and passes through the guide roller 2. The staff rotates the handwheel 12 by hand, so that the handwheel 12 drives the first bidirectional screw rod 11 fixedly connected to rotate. Due to the sliding limit between the two limit plates 14 and the loading seat 1, the first bidirectional screw rod 11 drives the two screw sleeves 13 to approach each other, and the two screw sleeves 13 drive the two limit plates 14 to move closer. At the same time, since the two transmission wheels 16 are fixedly connected to the first bidirectional screw rod 11 and the second bidirectional screw rod 15 respectively, and a transmission belt 17 is connected between the two transmission wheels 16, the second bidirectional screw rod 15 rotates synchronously with the first bidirectional screw rod 11.

When it is necessary to When the steel is extruded and loaded, the PLC controller 3 is used to start the drive motor 2, so that the output shaft of the drive motor 2 drives the fixedly connected guide rotating rod 1 6 to rotate. Since the guide rotating rod 1 6 and the rotating rod 1 22 are fixedly connected with the pulley 1 21 and the pulley 23, and the belt 24 is transmitted between the pulley 1 21 and the pulley 23, the rotating rod 1 22 rotates synchronously with the guide rotating rod 1 6. Due to the engagement between the first gear 25 and the second gear 27, the rotating rod 1 22 can utilize the engagement between the first gear 25 and the second gear 27 to drive the rotating rod 1 The rotating rod 26 rotates, and at the same time, the rotating rod 1 22 and the rotating rod 2 26 drive the two fixedly connected brush rollers 28 to rotate, so as to clean the impurities and dust on both sides of the steel. Since the guide rotating rod 1 6 and the guide rotating rod 2 8 are fixedly connected with two synchronous wheels 9, and a synchronous belt 10 is transmitted between the two synchronous wheels 9, the guide rotating rod 1 6 and the guide rotating rod 2 8 rotate synchronously, and drive the two fixedly connected guide rollers 1 7 and the guide roller 2 to rotate, and transport and feed the steel. At the same time, they cooperate with multiple squeezing rollers 5 to extrude and shape the steel to improve the flatness of the steel.
