Description
Technical field
The present invention relates to mold manufacture field, specially a kind of steel pipe automatic punching machine.
Background technique
Tower crane is a kind of most common lifting equipment also known as " derrick crane " on construction site, with a section spreading
(height) (referred to as " standard knot "), for hanging the raw material of the constructions such as working reinforcing bar, wooden flute, concrete, steel pipe.Tower crane standard
Section is the important component of a tower crane, is needed in the manufacturing process for the brace wherein used on the standard knot of tower crane by round tube
Both ends flatten, and cut out inclined angle.
Traditional processing method is required for being first cut into round tube after length, then by the tube ends of fixed length on punching machine
It flattens, the processing efficiency of this method is not high, entitled " the steel pipe fast ram segmentation of Patent No. " CN104384370B ", patent
Machine " patent in disclose a kind of machine that can continue sectional stamping, including leading truck, punching machine, punch die, die punching frame and material containing
Frame, punch die be equipped with the face with slope, the machine due at the punching press segmentation of punch die part two surface slopes it is identical, so being segmented out
The shapes of two sections be all identical, therefore continual can carry out segmentation flattening, improve production efficiency.But
Since the device is in feeding, leading truck is obliquely installed, when steel pipe is oblique to be entered to expect on punch die, the both ends of the steel pipe after punching press
Notch it is in irregular shape, be easy to appear gap, be not easy to it is subsequent transport or installation etc. operation.
Summary of the invention
The invention is intended to provide a kind of steel pipe automatic punching machine, to solve in the prior art, since steel pipe is by oblique pan feeding
To punch die, the phenomenon that both ends notch of steel pipe is easy to appear gap after being stamped.
The present invention provides base case: steel pipe automatic punching machine, including workbench, the guiding being respectively positioned on above workbench
Plate and punching mechanism；Guide plate close to one end of punching mechanism hingedly on the table；Punching mechanism includes moving reciprocatingly
The both ends of upper trimming die and fixed lower punch on the table, upper trimming die and lower punch are inclined-plane, and the lower plane of upper trimming die is set
There is formed punch, plane is equipped with the groove matched with formed punch on lower punch；Wherein, it is additionally provided with elevating mechanism below workbench, rises
Descending mechanism includes inclined support plate, first connecting rod, connecting rod, pedestal and the second connecting rod, and support plate is located at going out for lower punch
The lower end of the obliquely downward of material mouth, support plate is connected to the upper end of first connecting rod；The lower end of first connecting rod is hinged on connecting rod
One end；The other end of connecting rod and the lower end of the second connecting rod are hinged, are hinged on pedestal in the middle part of connecting rod；The upper end of second connecting rod
It offsets with guide plate far from the lower end of punching mechanism.
The working principle of base case: when work, start punching mechanism, upper trimming die moves reciprocatingly in the vertical direction；
Steel pipe on guide plate is pushed in punching mechanism, so that lower die, general who has surrendered's steel pipe pressure under upper trimming die are stretched out in one end of steel pipe
Disconnected, the waste material after punching press is fallen into groove；Steel pipe after punching press is good is since center of gravity is close to one end that lower punch exports, in gravity
Under effect, the steel pipe after punching press is good is fallen in the support plate of lower section；Support plate decline, first connecting rod decline, the second connection
Bar rises, and the one end for driving leading truck and the second connecting rod to offset rises, and leading truck tilts at this time, and steel pipe is made in the gravity of itself
It is slided into punching mechanism under along leading truck；When steel pipe slides into punching mechanism, the good steel pipe of punching press is also from support
It is slid on plate, at this point, the second connecting rod declines under the action of guide plate, first connecting rod rises, and elevating mechanism restores balance
State, steel pipe no longer slide after sliding on lower punch, and are horizontally arranged on lower punch；Upper trimming die decline carries out punching press, punching
Steel pipe after pressing is fallen, and guide plate inclination, steel pipe enters punching mechanism, and punching mechanism carries out punching press, completes continuous operation.
Elevating mechanism is set, changes the state of elevating mechanism using steel pipe, is i.e. lengths of steel pipes after punching press slides into elevating mechanism
In, elevating mechanism inclination, steel pipe inclination to be punched slides into punching mechanism；After lengths of steel pipes slides from elevating mechanism, lifting
Mechanism restores balance again under the action of steel pipe to be punched, and then level is stuck in punching mechanism steel pipe to be punched, completes
Punching operation without in addition setting driving mechanism, and ensure that steel pipe is horizontality when by punching press, therefore will not
There is the phenomenon that gap, convenient for subsequent assembling and transport etc..
The beneficial effect of base case is: 1. during the loading and unloading of punching mechanism, pass through elevating mechanism state
Change, achievees the purpose that automatic feed/discharge；2. steel pipe is in heeling condition when comparing former punching press, after elevating mechanism, though
So in charging still by the way of inclination charging, but after the completion of charging, steel pipe can be horizontally arranged in punching mechanism,
Therefore the phenomenon that being not in gap in binder.
Preferred embodiment one: as the preferred of basic scheme, scraping wings is slidably connected on guide plate.The utility model has the advantages that guiding
When plate tilts, scraping wings glides along guide plate, so that steel pipe be pushed to glide, ensure that the smooth downslide of steel pipe；Meanwhile it utilizing
The cooperation of scraping wings and the second connecting rod further ensures the reset of elevating mechanism.
Preferred embodiment two: as the preferred of basic scheme, pedestal is positioned close to the side of guide plate.The utility model has the advantages that will
Pedestal is positioned close to the side of guide plate, ensure that one end energy of guide plate under the action of when the steel pipe after punching press is good is fallen
Smoothly rise, steel pipe can be slided into smoothly and carry out punching press in punching mechanism.
Preferred embodiment three: preferably two it is preferred, be rotatably connected to gear on the side of workbench, the second connection
Bar is provided with the rack gear engaged with gear close to the side of workbench.The utility model has the advantages that setting gear and rack gear, utilize rack-and-pinion
Engaged transmission, ensure that the second connecting rod movement stationarity, to ensure that the stationarity that steel pipe is placed on guide plate.
Preferred embodiment four: preferably three it is preferred, support plate is connected with collecting box far from one end of workbench.Have
Beneficial effect: setting collecting box, the steel pipe slid from support plate directly fall into collecting box, avoid the collection operation to steel pipe.
Preferred embodiment five: preferably four it is preferred, scrap collecting tank is slidably connected in groove.The utility model has the advantages that
Waste material after punching press is fallen directly into scrap collecting tank, when waste from stacking mostly after, slide scrap collecting tank, that is, can be taken off waste material
Collecting box completes the cleaning of waste material.
