SU823154A1 - Device for cutting polymeric materials - Google Patents

Description

The invention relates to devices for cutting polymeric materials and can be used, for example, in mockup design in design and research institutes, as well as in schools, palaces of pioneers, etc.

. The closest to the present invention is a device for cutting up to-dimensional, dimensional materials, comprising a horn plate with a slot located on its surface. A limiting ruler and a bracket with a heated string passing through the notches of F and T 1.,

However, the known device performs cutting of a material in a limited range of angles with a low cut surface quality,

The purpose of the invention is to improve the quality of cutting and increase operational capabilities.

This goal is achieved by the fact that the device for cutting polymer

materials containing a base plate with a slot located on its top of the upper limit ruler

.and a bracket with a heated string passing through the plate slot is equipped with a movable feed and adjustable npm HMHSj & J sliders mounted on the base plate and fixed on the plate with a guide bar, and the bracket is mounted on the latter with the possibility of displacement.

The presser slider is provided with rollers located on the surface of the slider facing the string.

Fig, I shows the described device, a general view; in fig. 2 section A-A in FIG. one; FIG. 3: Section BB in FIG. 2; in fig. 4 options for making a cut: a) on a straight line, b) at an angle, c) on a cylinder.

Claims (2)

The device-o contains a support plate 1, in which clamping band 3 is installed in mutually intersecting grooves 2 and adjustable feed slide 3 4 is movable by means of weights 5 through blocks 6. In slide 4, a rod 7 is mounted, which interacts with the limit switch 8, providing cutoff of electric current at the end of cutting. In the slider 3, the support rollers 9 are mounted. In the groove of the guide bar 10 fixed to the base plate 1, the bracket 11 is mounted so that it can move along the groove and is fixed in the groove by means of a screw 12. In the bracket 11 by cams. 13, the upper end of the string 14 is fastened. The lower end of the string is fastened with cams 35 located in housing 16 B. The housing 16 has slots J 7 to prevent the string from overheating 14. To prevent the string from bending, a spring 18 is installed in the case. division 19 and a carriage 20 is installed with the possibility of movement and adjustment to a predetermined size. In the carriage 20, the upper end of the axis 21 is fixed, and the lower end is fixed in the holes 22 of the base plate 1. A ruler 23 is glued on to set the material to the back dimension on the base plate and to fix the specified radius and material direction are limited; 24 attached to the base plate with screws 25. From above, the material is fastened by a strap 26 moving along the guides of the rack 27 fixedly attached to the string 24. The device is operated as follows. The movable ruler 24 is set to a predetermined size along the ruler 23 and fixed with screws 25. The slider 4 is withdrawn and the material is inserted which rests against the string 14 with the front surface. From the lateral displacement, the material abuts the surface with the string 14. fastened with slider 3, and from the upper - with clamping plate 26. To start cutting, stresses are applied to string 14. Material is fed with weights 5 through blocks 6 ..- Once the entire volume is cut and the slider 4 feeds to the string, triggered end switch 8 ... . To cut the material at given angles, the pillars 11 are moved along the groove of the strip 10 and secured to a predetermined size (Fig. 4b). For insertion of the cylindrical shape, the carriage 20 with the axis 21 is set to the specified size, the axis is inserted into the material, and the lower part of the axis is fixed in the holes 22. The material is rotated around the axis manually, the sliders are turned off. The use of the invention allows the material to be cut in an unlimited range: in length, at different angles, cylindrical and conical. The use of a string, heated by electric current and rigidly fixed, allows the material to be cut with a high quality cutting surface. . . Claim 1. A device for cutting polymeric materials containing a base plate with a slot, a restrictive ruler located on its surface and a bracket with a heated string passing through the slot of the plate, characterized in that, in order to improve the quality of the cut and increase the operational capabilities, the device It is equipped with a movable feeder and adjuster clamping sliders mounted on the base plate and a guide bar fixed to the plate, and the ycTaHOBneH-aa bracket is movable. 2. The device according to claim 1, about tl and which means that the pressure slider is provided with rollers located on the surface of the slider facing the string.
