Description

The invention relates to mechanical engineering and can be used for the automated manufacture of metal parts of complex configuration, such as sleeves, from a metal tube.

A device for manufacturing parts from piece blanks is known, which contains a punch, a die and a revolving feed mechanism, including a transport disk with slots for parts, a ratchet mechanism, locking pawns and a friction brake. The disadvantages of this device are the comparative complexity of its construction. material. .

The closest to the invention to the technical essence and the achieved result is a device for the manufacture of parts from a lengthy material containing the upper and lower plates, shape tools, a slider, two dL knives, pieces of dimensional workpiece, one of which is mounted on the slider, an ejector of finished products and a mechanism filing lengthy material la 2.

The disadvantages of this device are the impossibility of obtaining on it products of various configurations from tubular material and the inaccurate accuracy of the obtained products.

The purpose of the invention is the expansion of the nomenclature manufactured ;; LIE and LI and increase their dimensional accuracy.

The goal is achieved by the fact that a device for manufacturing products from a long material, containing upper and lower plates, shaping tools, a slider, two knives for cutting dimensional workpieces, one of which is mounted on a slider, an ejector of finished products and a long material feed mechanism, equipped with an intermediate plate placed between the upper and lower alites, spring-loaded to the upper plate and elements of orientation of the workpiece, mounted in a slider, which is mounted on an intermediate plate movably in a plane perpendicular to the direction of feed of elongated material ,. One of the shaping tools is mounted on the slider with the ability to interact with the upper plate and is spring-loaded relative to the slider, while the slider and the knives have holes for long material, and in the upper plate there is a through groove, the length of which is in the direction of movement

the slider exceeds the stroke of the latter, and the ejector is attached to the slider. The device can be equipped with additional driven shape-forming tools installed in grooves made in the orientation elements of the workpiece.

FIG. 1 shows the device in the initial position; in fig. 2 in the closed state) in FIG. 3 section aa on fig .- 2.,

The device (Fig. 1) contains the upper plate 1, the lower plate 2, the slider 3 mounted on the intermediate plate 4. The cutting knives 5 and 6 are mounted on the slider 3 and the intermediate plate. 4 respectively. The knives 5 and b form with their mating surfaces as they move the cutting plane. A wedge 7 is installed in the upper plate to act on the slider 3, which is spring-loaded toward the wedge 7 by a spring 8 mounted on the guide rod 9, which is also the stroke limiter of the slider 3.

In the bore 10- (FIG. 3) on either side of the axis t, the orientation elements of the workpiece 11 are installed. One of the mold tools is a stationary punch 12 fixed on the bottom plate 2, the axis of which coincides with the axis “.

The ejector 13 (FIG. 1), mounted in the longitudinal groove 14 of the intermediate gate 4, is fixed on the slider 3 and has an abutting plane b, limiting the stroke of the rod material,

In the boring 15 of the sliders 3, the shaping tool is installed - a punch 16 pressed against the pin. 17 by a spring 18 in the direction of the upper plate 1. In the slider 3 and the knives 5 and b there are respectively holes 19-21, and in the upper plate 1 there is a through groove 22, the length of which exceeds the stroke of the slider 3, for feeding the bar material

Supports 23 (fig. 3) are installed in the upper plate to act on the intermediate plate 4 by means of kchtsih slats 24 of the slider 3.

In elements 11, bores 25 are made, in which additional shaping elements are installed radial punches. 26.

On the top plate 1 there is a wedge 27, and on the bottom plate 2 on the axle 28 Eichagi 29 interacting with the punches 26..

In the cavity 30, formed by elements 11 and punches 26, springs 31 are installed,

Springs 32 are installed between the upper plate (Fig. 1) and the lower plate 2. The interlocking of the stamp plates is provided with a movable crosshead 33. In the case 34 for feeding the bar, the material has paws 35, which are pressed against each other by springs 36 ,, the case 34 is suspended to the stationary frame 37 on levers 38, which form a rhombus and axles 39 pivotally fastened together. At two opposite corners of the rhombus lying in a horizontal plane, rollers 40 DL9 are mounted on them by wedges 41 mounted by a hollow pusher 42 mounted on a mobile t The version 33. In the roller cover 3, a pawl with a spring 44 is installed with a limited horizontal movement. The guide and the columns and bushes forming, together with the plates 1 and 2, the stamp block are not shown. The operation of the device is shown on the example of the manufacture of a copper conductive material, for the sleeves of connecting cable. When moving the cross bar 33 down the wedge 41, I will act on the rollers 40, turn the levers 38 and move the body 34 down. Dogs 35 feed a bar material (copper tube) below the cut plane to the stop plane b. . The doggie 43, pressed against the rod material by the spring 44, prevents the return of the rod material and fixes it in a new position. Wedge 7, acting on the slider shifts it right along with the ejector 13, while the knife 5, offset from the knife b, cuts off the copper billet from the bar material moving together with the slider 3. When the polyolead 3 is moved to the extreme right position, the punch 16 is aligned coaxially with the punch 12. With further movement, the upper plate 1, acting on the end face of the punch 16, moves it towards the punch 12. The punch 16. acts on the end of the workpiece and moves it down along the axis B. When the workpiece is moved, it is permanently elastically fixed by elements 11. In the process of further moving 2 3 of the upper plate 1, the intermediate plate 4 is moved down. Punches 16 and 12, moving towards each other, produce the molding of the workpiece and the distribution of its ends. At the same time, the wedge 27 acts on the levers 29, which move the punches 26, which nuzzle the side surface of the workpiece. The end of the process of machining the workpiece corresponds to the closed position of the device (Fig. 2 and Fig. 3). During the return stroke of the crosshead 33, the top plate returns to the inlet position by the springs 32. The pusher 13 expands the elements 11, compressing the springs 31, and removes the finished part from the stamping area. After reaching the extreme upper position of the overhang 33, the manufacturing cycle of the part ends. The further manufacturing process of the parts takes place,. similar to that described. The prepursed device allows to manufacture parts of a complex configuration from a bar and, in particular, pipe material, the device is characterized by high precision in the production of parts, due to the fact that transverse movement of the cut piece is excluded during its machining operations. The shape change of the workpiece is carried out in one element of basing.
