(54) DEVICE FOR MANUFACTURING PRODUCTS FROM LONG-LARGE Billets

(57) A device for manufacturing products from lengthy workpieces. Usage: leather goods production. SUMMARY OF THE INVENTION: the device comprises a table along which the workpiece is moved under the yMi, a cutting tool, a guiding device that includes flaps forming a V-shaped groove and their drive. During operation, the workpiece device enters the chute, while its lateral edges are bent inward and thereby increase the stiffness of the workpiece, which contributes to its normal movement along the flaps. 4 ill.

The invention relates to leather goods production, and more particularly, to devices for manufacturing products from lengthy workpieces, such as belts, nerds, and the like. and storing them in a drive.

A device is known for manufacturing products from long workpieces comprising a material feeding mechanism, a chain conveyor, and cutting tools.

The disadvantages of the device are the complexity of the design, the inconvenience of storing manufactured parts.

The closest in technical essence to the proposal is a known device comprising a workpiece feed mechanism, a table with a guide and a cutting tool.

A disadvantage of the known device is: inconvenience of operation due to the lack of devices for storing and storing the cut parts for a long workpiece, which negatively affects the operational properties of the device.

The purpose of the invention is to increase its operational properties.

This goal is achieved in that the known device comprising a table with a guide, a workpiece feeding mechanism and a cutting tool is provided with two notch dies located on the sides of the guide with a hopper for storing the trimmed parts of a lengthy workpiece and a workpiece guiding device including two shutters hinged with their upper edges, forming a V-shaped groove, located with the possibility of interaction of the shutters with the side edges of the workpiece e cylinders kinematically connected to the leaflets with the possibility of their separation to the sides, while located under the leaflets

Figure 1 shows a part of a General view of the device in a perspective view; figure 2 is the same when viewed from the side; in Fig.3 - section aa in Fig.2; figure 4 is a view of B in figure 2.

The device comprises a table 1 with a guide, a feed mechanism for the workpiece 2, a cutting tool 3, and a guide device including two pivotally attached flaps 4 located with the formation of a figurative head, power cylinders kinematically connected with the flaps 4 The feed mechanism includes a roll | 1kb, a pinch roller 7 with a pressure cylinder 8 of the cylinder 8. In addition, the device includes a method for applying (cutting) 9, including a pneumatic cylinder 10, a tool 11 and supports 12 for punching marks 13, and also the bunker 14 nak an opitel of the cut parts 15 of a lengthy workpiece 2.

The device operates as follows.

The feed mechanism feeds the workpiece 2 along the table 1. The corresponding technological operations are performed on the workpieces, the last of which consists in cutting off a part of the workpiece 2 of a certain length by means of a cutting tool 3. Until the moment of cutting, the end of the workpiece enters between the leaves 4 forming a V-shaped gutter. In this case, the shape of the trough provides bending of the lateral edges of the workpiece 2, which gives rigidity to the workpiece, eliminates the wave formation of its surface associated with friction of the workpiece against the sash 4 and its lengthiness and rigidity. The bending of the side edges of the workpiece 2 gives it rigidity and ensures the advancement of the workpiece along the wings 4. After placing the workpiece 2 along the entire length of the wings 4

the cutting tool 3 melts. The cut-off part of the workpiece 2 remains in the groove formed by the leaves 4. The process is repeated. After a series of cut pieces of workpieces from one or more are acopit in the chute formed by the leaves 4, the power cylinders 5 are activated and the cut parts fall into the hopper 6. The leaves are closed and the process continues. The shutters 4 can be made not only flat, but also slightly curved outward, which will contribute to a more effective bending of the side edges of the workpiece 2. The proposed device has a simple structure, reliability and provides ease of use, which generally improves operational properties,
