Description

Continuous stamping device for metal processing and stamping method thereof

technical field

The invention belongs to the technical field of stamping equipment, in particular to a continuous stamping device for metal processing and a stamping method thereof.

Background technique

Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation force and deform in the mold, so as to obtain product parts of a certain shape, size and performance. Among them, for thin steel strips, continuous punching is usually required to complete the opening of holes.

The continuous stamping device for metal processing in the prior art usually puts a thin steel strip on the worktable during use, and clamps and fixes it at multiple places on the side to realize positioning and stably stamp and punch holes. However, due to The thin steel strip has its own curvature and radian when it is laid. When it is actually clamped and tightened, the middle is easy to bulge. The flatness after the actual laying is poor. After manual leveling, it needs to be fixed at the same time. The actual operation is more troublesome and delays The actual punching time reduces the processing efficiency of batch metal parts, and the actual leveling effect is average. When the leveling level is poor, the positioning of the holes after continuous punching is inaccurate, and the processing effect is not good.

In addition, the metal processing continuous stamping device in the prior art usually uses a detachable punching die head when punching holes with different apertures. In order to stabilize the punching quality, a tubular punching die with a cavity at the bottom is generally used However, after the actual punching, part of the metal scrap after punching and segmentation is blocked in the punching die head. In fact, there is interference in the continuous punching and punching process, resulting in punching failure. Clean up the waste in time, take out the waste from the punching die head, increase the cascading process, and the operation is troublesome.

9. The press method of a metal working continuous press apparatus according to any one of claims 1 to 8, wherein: the method comprises the following stamping steps:

the first step is as follows: when a steel strip to be punched is placed, keeping two groups of compression roller mechanisms (11) symmetrically distributed in the middle of the top of the workbench (1), starting the air pump (21), leading the air pump (21) to introduce air into the communicating mechanism (19), and leading the fed air into each group of side edge sleeves (14) through the communicating mechanism (19), leading the movable plugs (13) in the side edge sleeves (14) to move upwards under the pushing of the air, leading the curved rod (10) to move upwards, further driving the compression roller mechanisms (11) fixedly connected with the curved rod (10) to move upwards, and sliding the steel strip into the space between the two groups of compression roller mechanisms (11) from the side surface;

the second step: after the steel belt is placed, an air pump (21) is closed, so that two groups of compression roller mechanisms (11) move downwards under the elastic resetting action of a spring (12) and press the middle part of the steel belt tightly, then telescopic rods (18) are started, so that the telescopic rods (18) at two sides drive two groups of movable frames (8) positioned in the middle part to move reversely to two sides, so that the compression roller mechanisms (11) move to the left side and the right side along the top surface of the steel belt and push the steel belt to be extruded from the middle part to the two sides, the steel belt is gradually leveled, and the compression positioning is finished when the two groups of compression roller mechanisms (11) move to the edge of the steel belt and are stopped;

the third step: after the steel band is positioned and leveled, track mechanism (4) is started, so that lifting rod (5) and die head (6) move to the target punching position, and lifting rod (5) is started, so that die head (6) rapidly impacts the steel band downwards, round plate waste is punched out along with the steel band, simultaneously, round plate waste enters into the inside of die head (6) and extrudes push rod (28), so that push rod (28) drives baffle (27) to press double-gauge spring (26), after moving up die head (6), spring (26) elastic reset and drive push rod (28) reset and move down, the round plate waste clamped inside die head (6) is pushed out, automatic blockage clearing is completed, and continuous punching is performed along with the movement of lifting rod (5) along track mechanism (4).
