Abstract

The utility model discloses an automatically facing the middle part of a feeding device for the profile cooling bending processing device. The utility model is characterized in that: the two ends of a feeding machine frame are respectively installed with a rocker arm, and the rocker arm is installed with two connected rods to form a movable parallelogram frame. The feeding device is connected at the two connection rod. The utility model makes the rib achieve automatically facing the middle part in the feeding course, and the feeding direction and the sending motivation always direct to the core of a chuck at the support point of the feeding end, which ensures the rib pass smoothly without forming the geometric dead point in sending. At the same time, the utility model can't cause any limit to left and right remove of the bending of the edge machine frame and the left and right remove regulation of the bending support point distance.

Description

A kind of automatic centering feed arrangement that is used for the section bar cold-bending processing equipment

The utility model belongs to the hull frame process equipment, specifically relates to the automatic centering feed arrangement of section bar cold-bending processing equipment.

The shipbuilding sections cold-bending processing equipment generally is equipped with three frames, i.e. a mid frame 6 and two

limit frames

5,7, see also accompanying drawing, mid frame 6 is provided with central bearing point, the limit frame is provided with the limit fulcrum, when bent frame 1, constitute three bending fulcrums, a kind of during work is that mid frame is motionless, the both sides frame moves forward and backward simultaneously, another kind of section bar cold-bending processing equipment is that the both sides frame maintains static, mid frame moves forward and backward, just can carry out bending machining to one section rib between two limit frames, charging along with feed arrangement, crooked piecemeal rib, finish the bending forming processing of whole root bone at last, because the curvature of the rib after the bending is that each section is inequality, so rib send to will be simultaneously three fulcrums by three frames be very difficult, must adjust the position of fulcrum at any time, rib can pass through, otherwise will be stuck, fill process for manual operation section bar cold-bending processing equipment, the operator must stare at all the time and look three fulcrums, send to according to rib and to bump situation with the fulcrum card in moving, at any time start main curved oil cylinder to dodge it, reach the purpose of charging, but then do not allow individual's operation to intervene for automatic section bar cold-bending processing equipment, automatic feed swimmingly, must eliminate the stuck phenomenon in the fill process, automatically the section bar cold-bending processing equipment generally is provided with cover front and back avoiding device automatically at central bearing point, the problem that solves is exactly rib stuck on two limit fulcrums, domestic prior art is none desirable solution still, feed lead rail 4 in the accompanying drawing is established single-revolution fulcrum L in the outside of feed end limit frame 5, the center line of feed lead rail 4 (also being the power direction of sending to of rib simultaneously) is by the L point, pass through the fulcrum I on feed end limit simultaneously, curvature increasing along with frame bending, the pendulum angle of feed lead rail also strengthens, departing from that rib sends that power direction and I order to is also increasing, is easy to generate self-locking and stuck; The feed arrangement of the section bar cold-bending processing equipment of external Germany is located at the revolution fulcrum on the on-axis point of feed end fulcrum, in order to abdicate the passage that rib is sent to, its actual revolution fulcrum can only be arranged on the superjacent air space and the following side space of feed end limit frame, this just limited the limit frame be provided with before and after or the guide rail of move left and right, force the limit frame to fix and not removable, the distance of two limit fulcrums is non-adjustable, the rib of all size specification can only be crooked in a fixing distance, influenced the forming quality of rib.

The purpose of this utility model is to provide a kind of improved automatic centering feed arrangement that is used for the section bar cold-bending processing equipment, it can make rib realize automatic centering in the automatic feed process, feedstock direction and send the chuck center that power points to the feed end fulcrum all the time to guarantees that rib sends Shi Buhui to and constitute how much dead points and stuck at this.

The technical solution of the utility model is achieved in that a kind of automatic centering feed arrangement that is used for the section bar cold-bending processing equipment, it mainly comprises feed end limit frame and the feed arrangement that is attached thereto, it is characterized in that: a rocking arm is respectively adorned at the two ends in the charging frame, two connecting rods are housed on rocking arm, form mobilizable parallelogram lever, feed arrangement is connected on two connecting rods.

The utility model makes rib realize automatic centering in fill process, feedstock direction and send the chuck center that power points to the feed end fulcrum all the time to, guarantee that rib sends that Shi Buhui forms how much dead points to and can smooth and easy passing through, simultaneously can the opposite side frame do not carry out the crooked move left and right adjustment that moving forward and backward and carrying out crooked pivot distance and cause any restriction.

Fig. 3 is the schematic diagram of the utility model when the rib male bend

Fig. 4 is the utility model at the recessed schematic diagram when curved of rib

The utility model will be further described below in conjunction with drawings and Examples.

The utility model is a kind of automatic centering feed arrangement that is used for the section bar cold-bending processing equipment, mainly comprise feed end limit frame and the feed arrangement that is attached thereto, it is different from prior art and is: respectively adorn a rocking arm 3 at the two ends of charging frame 5, two connecting rods 2 are housed on rocking arm 3, form mobilizable parallelogram lever, feed arrangement 8 is connected on two connecting rods 2, respectively adorn an engaging lug 9 at the two ends of charging frame 5 in the enforcement, engaging lug 9 is mobilizable the connection with rocking arm 3, promptly on the engaging lug of charging frame, A is arranged, two fulcrums of B, four between connecting rod 2 and the rocking arm 3 are connected fulcrum C, D, E, F is can rotating relatively hinged point, feed arrangement is arranged on two connecting rods 2 between the rocking arm 3, two fulcrum G on the feed arrangement center line, H is hinged and connected with two connecting rods 2 respectively, two rocking arms 3 and two connecting rods 2 are isometric, its geometrical relationship is: BC=AF, CD=GH=EF, DG=CH=BI, AB=CF=DE, the quadrangle of Gou Chenging: ABDE like this, EFHG, AIGE, AIHF is parallelogram, rib 1 is under male bend and recessed curved any curvature situation, no matter the framework of parallelogram is in which position, the center line that all can guarantee mobile feed lead rail points to the I point, guarantee the feeding direction of rib and send power to, thereby guaranteed that the rib section bar does not cause how much smooth and easy the passing through of dead points energy when these fulcrum advance and retreat all the time by the I point.
