Description

. (5) DEVICE FOR CORRUGATING BELT BILLS

one

The invention relates to the processing of metals by pressure, in particular to equipment for corrugating sheet material.

A device for the manufacture of corrugated products is known, comprising forming tools, tools mounted on both sides of the material, each being connected by an individual drive l. Yu

However, this device does not allow for making corrugations in small steps.

Closest to the present invention is a device for corrugating the tape, containing two sets of them and the bottom bending knives of three each, mounted on the frame, while the symmetrical bending knives of the top Kits are pairwise interconnected, and the pairs are installed with possible 20 relative displacement of G2j.

However, on a known device, each set of bending knives may

to mold only two corrugations in one working stroke.

The purpose of the invention is to increase productivity by increasing the number of corrugations molded in one working stroke.

This goal is achieved by the fact that a device for corrugating a tape blank, containing two sets of upper and lower bending knives, symmetric about its axis, each consisting of two side and one central, each bending knife of one upper set is rigidly connected to the corresponding the knife of the other set, and the pairs of connected knives are installed with the possibility of relative movement, provided with a support bar, rigidly connected with the central knives of the lower sets, of a movable lower trail A coaxially rigidly connected side knives of the lower sets and interacting with the support bar, as well as semi-matrices fixedly mounted on both sides of each upper set, the side knives of each upper set are rigidly connected to each other, while the longitudinal grooves are made in them, and the central The knives are equipped with restrictive pins, the ends of which are placed in the aforementioned grooves and the weights mounted on their non-working ends. FIG. Figure 1 shows the device at the end of the layout, a general view of FIG. 2-5 - sequential operation of one set of bending knives. The device contains fixed on base 1 by means of a half mat and legs-k placed between them two sets of upper bending knives, each consisting of two lateral 5 and central 6. Side knives 5 of both sets are connected by a traverse 7 with a rod 8 of the power cylinder ra. The side knives 5 have a common base E, in which a longitudinal groove 10 is made, a length corresponding to two depths of the formed corrugations, as well as an axial groove for accommodating the central bending knife 6, which is provided with a restrictive pin II installed in the groove 10. At the non-working ends of the bending knives 6 installed sinker 12. On semi-matrix 1 fixed stops 13 for blanks. The 3 lower parts of the device contain sets of lower bending knives, each consisting of two side .14 and central 15. Central neutral bending knives 15 are fixed rigidly on a support bar 16 placed on the stops 17, and the side blades are fixed on a traverse 18 connected with rod 19 of the power cylinder, and guided through columns 20. The central bending knives 15 are provided with two forming surfaces. The device works as follows. Two workpieces 21 are mounted on the stops 13 and the tops of the bending knives 15. The upper power cylinder is turned on, and the rod 8 moves the yoke 7 with the bending knives 5 and 6, while the central knives 6 are pushed to the depth of the corrugations and formed the first corrugation. After the central knives 6 have finished forming the corrugation and have stopped, the molding of the knurled 82 is bent. 4 Zhami 5 semi-tofugs adjacent to the formed corrugation. At the end of the movement of the knives 3 from the rod 19 of the lower pneumatic cylinder, the traverse 18 begins to move with the knives 1, which completes the design of the second and third corrugations. After the yoke 18 contacts the support bar 16, the associated bending knives 15 begin to rise and simultaneously with the bending knives 1 and, approaching the semi-matrix t and 2, the last two half-hems are formed. After the power cylinders are disconnected, the knives return to their original position and the parts are removed. The proposed device, in addition to improved performance, is easy to manufacture and operate, as well as compact. The invention of the Device for corrugating a tape blank, containing two sets of upper and lower bending knives, each symmetrical about its axis, each consisting of two side and one central knives, each bending knife of one upper set being rigidly connected with the corresponding knife of the other. The set, and the pair of knives connected, are installed with the possibility of relative movement, characterized in that, in order to increase productivity by increasing the number of corrugations molded in one working one, it is provided with a support bar, rigidly connected with the central knives of the lower sets, a movable lower head plate, rigidly connected with the side knives of the lower sets and interacting with the support bar, as well as semi-matrix fixedly mounted on both sides of each top set, the side knives of each The upper set is rigidly connected to each other, with longitudinal grooves in them, and the central knives are provided with restrictive pins, the ends of which are placed in the said grooves, and m in their non-working ends, information sources, the received note in the examination certificate USSR 1.Avtorskoe №, Cl.
