TECHNICAL FIELD

[0001] The utility model relates to punch mechanical field especially is involved in a kind of staggered peak punch press device using split slider. BACKGROUND

[0002] Traditional punch mechanism usually uses following two ways to improve work efficiency: one is to set multiple work positions die mould in the same punch mechanism to punch multiple workpieces simultaneously;Second is to establish multiple punch production lines, and use multiple punch mechanisms to complete punch work.

[0003] The existing invention patent CN201610379512.2 discloses a kind of multi-station punch press, including workbench, driving device, frame body and installation on the punch cylinder of frame body, the bottom of frame body is matched with workbench, driving device is connected with frame body, multiple moulds are provided on workbench, and driving device drives frame body to move along workbench.

[0004] The existing utility model CN201620157832.9 discloses a kind of full-automatic punch press production line, including feeding conveying line, left and right material distribution robot, left material distribution line and right material distribution line;The left material distribution line includes left forming machine, first edge punching punch press, first punching punch press, riveting punch press, multi-station rotary feeding rack and left material pool, and the right material distribution line includes right forming machine, second edge punching punch press and right material pool.The utility model is alternated by left feeding table and right feeding table to carry out double area feeding, and its feeding speed is fast, the positioning mechanism on conveying belt can realize the automatic positioning of plate material, left and right material distribution robot can carry out asynchronous material distribution to plate material, and can adjust the different speed of each process of edge punching, punching and riveting slow, feeding conveying fast, which realizes full-automatic punch press production, and can control conveying speed according to plate material feeding conveying line, and it is also provided with multiple material distribution lines, so that it matches with the feeding speed of feeding conveying line, full-intelligent, automatic production, high production efficiency, low cost.

[0005] In the prior art, there is a problem that during the operation of a multi-station stamping mechanism, the die closing time of multiple stations may overlap, which may cause an increase in load peaks. In order to solve this problem, the design of the frame must be strengthened to make it more robust. However, this improvement may cause an increase in the weight of the frame. In addition, the introduction of a multi-pass stamping line inevitably increases the complexity of the stamping mechanism and requires additional steps to arrange the production of products on different lines. All these factors together lead to an increase in the complexity of the overall structure, the work flow becomes more complex, and the overall work efficiency and energy consumption are adversely affected. Content of the utility model

[0006] In order to solve the above problems, the utility model provides a staggered peak stamping device using split sliding blocks, which adopts a multi-station asynchronous stamping mode to disperse the peak stamping load, reduce the weight of the frame, and realize the lightweight and miniaturization of the mechanism.

[0007] In order to achieve the above purpose, the utility model designs a staggered peak stamping device using split sliding blocks, which includes a crankshaft, characterized in that a connecting rod connected to the split sliding blocks is sleeved in the middle section of the crankshaft, and the connecting rods of the split sliding blocks are installed at different angles on the crankshaft, so that the split sliding blocks stagger the peak stamping of the workpieces in different stations, thereby reducing the power demand of the crankshaft to the sliding blocks within a unit time, and reducing the stamping load during single die stamping. This design reduces the power demand of the crankshaft to the sliding blocks within a unit time, effectively disperses the peak load, and reduces the allowable load. At the same time, under this design, the strength of the crankshaft can be moderately reduced, so the weight of the crankshaft can also be reduced. This means that only a smaller driving force is needed to drive the movement of the crankshaft, thereby realizing the miniaturization of its driving system.

[0008] In order to realize the force balance of the workpieces during asynchronous stamping, the connecting rods of the split sliding blocks can be installed at different angles on the crankshaft in a center-symmetric manner in the middle section. In this way, the force balance of the workpieces during asynchronous stamping is realized.

[0009] As preferred, the crankshaft and the split slider are connected through a connecting rod. One end of the connecting rod is sleeved and installed on the crankshaft at different angular positions, and the other end of the connecting rod is connected with the split slider. The design of the connecting rod effectively converts the rotary motion of the crankshaft into the linear reciprocating stamping motion of the split slider. By adjusting the length and angle of the connecting rod, the movement amplitude and direction of the split slider can be ensured to match the required stamping part specifications, thereby meeting the requirements of stamping processing. Generally speaking, different effects can be obtained by selecting different connecting rod lengths and different phase angles; however, from a machine, the phase angles can be different, but the connecting rod lengths must be the same, otherwise the slider movement will be disorganized. That is, the movement amplitudes of the split sliders described below are different.

[0010] The split slider staggered peak stamping device designed by the utility model can stagger the mold closing time of different stations by using different angles of the crankshaft, adopts split sliders installed at different angles to perform asynchronous stamping on workpieces at different stations, avoids the problem of large peak load when all stations are stamped at the same time, thereby reducing the structural strength requirements of the crankshaft, the rack and other structures, reducing the weight of these structures, thereby realizing lightweight of the entire mechanism and reducing production cost.
