Technical Field
The utility model belongs to the technical field of the punch press manufacturing technology and specifically relates to a mechanism in punching press clearance is eliminated to punch press.
Background
The punch press drives a flywheel through a motor, and drives a crank connecting rod mechanism to enable a sliding block to move up and down through a clutch so as to drive a drawing die to form a steel plate. The double-acting means that the press is provided with two slide blocks which are an inner slide block and an outer slide block, the inner slide block drives a male die or a female die of the die, the outer slide block drives a blank holder on the die, the blank holder firstly acts to press the edge of a steel plate during drawing, and the inner slide block then acts to draw. Due to the problem of installation tolerance between the transmission gear and the connecting rod and between the connecting rod and the stamping sliding block, gaps often exist above the connecting holes during assembly, so that the stamping sliding block can move upwards when the punch presses, and the stamping precision is influenced.
Disclosure of Invention
The utility model provides a not enough to prior art, the utility model provides a mechanism in punching press clearance is eliminated on punch press carries out synchronous jack-up with the slider through the cylinder, does not have the clearance in the junction upper end of messenger's connecting rod and connecting block, makes the slider can not receive the existence in clearance and remove when the punching press, has guaranteed the machining precision.
The utility model provides a technical scheme that its technical problem adopted is: a mechanism for eliminating a stamping gap on a punch comprises a rack, a stamping assembly and a main slider, wherein the main slider is longitudinally connected on the rack in a sliding manner, the stamping assembly drives the main slider to stamp, the stamping assembly comprises a rotating wheel, a connecting rod and a stamping head, the lower end of the stamping head is fixed on the main slider, the upper end of the connecting rod is rotatably connected with the rotating wheel through a crankshaft, the lower end of the connecting rod is rotatably connected with the stamping head through a rotating shaft, a first air cylinder is further arranged on the rack, the lower end of a piston rod of the first air cylinder is fixedly connected with the main slider, the first air cylinder drives the main slider to drive the stamping head to move upwards, so that no gap exists between the rotating shaft and the crankshaft and the lower end of the connecting part of the connecting rod, and the first air cylinder adjusts the telescopic length of the piston rod according to a stamping stroke during stamping, therefore, no gap exists at the lower end of the connecting part of the rotating shaft, the crankshaft and the connecting rod.
In the above technical scheme, preferably, the stamping machine is further provided with an auxiliary sliding block, the auxiliary sliding block is arranged on the upper portion of the main sliding block and is longitudinally connected with the rack in a sliding manner, the rack is provided with a second cylinder for driving the auxiliary sliding block to move, the rack is provided with two stamping assemblies, the two stamping assemblies are respectively driven by transmission gears arranged on the rack, the two transmission gears are turned in opposite directions, and when the main sliding block moves downwards, the second cylinder drives the auxiliary sliding block to move upwards to offset stamping vibration.
The utility model has the advantages that: the lower end of a piston rod of an air cylinder is fixedly connected with the main sliding block, and in an initial state, the first air cylinder drives the main sliding block to drive the punching head to move upwards, so that no gap exists at the lower end of the connecting position of the rotating shaft, the crankshaft and the connecting rod, and the first air cylinder adjusts the telescopic length of the piston rod according to a punching stroke during punching, so that no gap exists at the lower end of the connecting position of the rotating shaft, the crankshaft and the connecting rod.
