Abstract
The utility model discloses a guide pin device for a punch, which converts the circular motion of a punch crank shaft into up and down linear motion of a die driven by a slide block, and comprises the crank shaft, saw teeth and a converting device; the converting device consists of a guide pole and a connecting rod which are connected into a whole by a pin; the connecting rod is connected with the crank shaft by a bearing; and the guide pole is connected with the slide block on the punch by the saw teeth. The original converting device is a bulb connecting rod mechanism which is difficult to be machined and has high machining precision requirement; and as the bulb clearance is difficult to be adjusted, the bottom dead point of the punch is not stable, and the punching precision is low, thus influencing the normal operation of the punch. As the guide pole, the connecting rod and the pin are connected, the guide pole and the pin have simple structure and are easy to be machined and installed, thus not only simplifying the structure and the machining, but also reducing the cost, ensuring the stability of the bottom dead point of the punch and the punching precision, and improving the working efficiency.
Description
Technical field
The utility model relates to the critical piece on a kind of machining punch press, particularly the circumference of bent axle is rotatablely moved to be transformed on punch press to drive slide block by the saw tooth and do upper and lower straight-line switching mechanism, the guide pillar pin assembly of punch press.
Background technology
Existing Chang Yong general punch press, usually adopt ball head connecting rod mechanism that crankshaft component and the slider part that is connected with bent axle linked into an integrated entity, and will rotatablely move by the circumference of bent axle and convert the upper and lower rectilinear motion of slide block to, but it is very high that the contact area of ball head connecting rod and ball seat requires, requirement on machining accuracy height, difficult processing, the size of contact area directly has influence on the adjustment in bulb gap, the too small bulb that easily causes in bulb gap is killed, the bulb excesssive gap easily causes punch press lower dead center instability, punching precision low again, and it affects the normal use of punch press always.
Number of patent application 200810025932.6 " a kind of high speed accurate numerical control press ", the movable connection structure of bulb contiguous block and pit is also still adopted in its switching mechanism, has above-mentioned drawback equally.
Summary of the invention
Technical problem to be solved in the utility model is: the guide pillar pin assembly that a kind of punch press is provided, link into an integrated entity by the bent axle and the slide block of this device punch press, the circular motion of bent axle is transformed into the upper and lower rectilinear motion of slide block, it is simple in structure, easily make, easily assemble, and improved the punching precision of punch press.
The technical scheme in the invention for solving the above technical problem, the guide pillar pin assembly of punch press comprises bent axle, saw tooth, slide block, conversion equipment, and described conversion equipment connects into integral body by pin with guide pillar, connecting rod and constitutes, connecting rod is connected with bent axle by bearing, and guide pillar is connected with slide block by the saw tooth.
Compared with prior art, advantage of the present utility model is: former is the not only difficult processing of ball head connecting rod mechanism, the requirement on machining accuracy height, also because of adjustment difficulty in bulb gap causes punch press lower dead center instability, punching precision is low, influence the operate as normal of punch press, now adopt being connected of guide pillar and pin, guide pillar, latch structure are simple, easily processing, easily install, promptly simplify the structure and process and reduced cost, guaranteed that the stability of punch press lower dead center and punching precision have improved operating efficiency again.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Connecting rod 2 by the integral body that screw is fixed into, has upper and lower two through hole by upper and lower two-section, and last through hole is connected with bent axle 1 by bearing, guarantees the punch press sufficient lubrication.
Cross through hole and vertical rectangular channel are arranged on the guide pillar 3, and through hole is vertical with rectangular channel communicates.
Connecting rod 2 inserts in the rectangular channel on the guide pillars 3, passes guide pillar and lower through-hole on the connecting rod respectively with pin 4 and connects whole, and saw tooth 5 is screwed on the bottom surface of guide pillar 3, saws tooth 5 and is fixed on the slide block of punch press by mode transfer gear 6 and gland.
Be to adopt being connected of guide pillar 3 and pin 4 being connected of connecting rod 2 and slide block.
During use, punch press work drive bent axle 1 is done circumference and is rotatablely moved, bent axle 1 is given connecting rod 2 with transmission of power, connecting rod 2 drives guide pillars 3 by bearing, pin 4 and the saw tooth 5 that links into an integrated entity with it is done upper and lower rectilinear motion, and saw tooth 5 is fixed on the slide block, then the mould that is driven on slide block and the slide block by the saw tooth is made upper and lower rectilinear motion, carries out punch process.
