Description

 The device relates to the field of metalworking, and more particularly to devices for layer-by-layer cutting of titanium blocks, and can be used to produce titanium chips.

 A device is known for cutting blocks of a titanium sponge [1], comprising a frame carrying a wedge knife and moving vertically in the guides of the bed, as well as a table for installing the block mounted in the bed with the possibility of horizontal movement.

 The disadvantage of this device is the complexity and bulkiness of the design, as well as the inability to obtain small chips.

 A device for cutting a titanium block by horizontal layering [2], the design of which is adopted as a prototype, comprising a receiving table for placing the block mounted on a bed, a cutting tool mounted on a carriage moving horizontally from the power cylinder, and clamps, located opposite each other with the possibility of mutual movement from the hydraulic cylinder, while the clamps are mounted on a bed with the possibility of joint horizontal movement above the table m and the carriage in the direction perpendicular to the movement of the carriage from the drive.

 The disadvantage of this device is that, due to the fact that the knife is movable, there is a spread of chips along the entire length of the stroke, which is why it is impossible to ensure high-quality collection of chips.

 In addition, the design of the table is complicated due to the need for lateral movement of the block with clamps, and the removal of the layer occurs in a few moves, which increases the processing time.

 The problem solved by the invention is to provide compact chip collection and simplify the design.

 This problem is solved as follows.

 In the known device for cutting a titanium block containing a bed with guides, a receiving table for a titanium block mounted on it, a cutting tool, a main working hydraulic cylinder and clamps located opposite each other with the possibility of mutual rapprochement on the mechanism for joint movement of the clamps with the titanium block, one of the clamps is connected to the hydraulic cylinder for moving it; according to the invention, the cutting tool is mounted stationary on the bed, and the mechanism for joint movement of the clamps with a titanium block made in the form of a slider connected with the main working hydraulic cylinder and mounted on the bed guides with the possibility of moving relative to the cutting tool and ensuring the contact of the titanium block with the cutting tool over the entire width of the titanium block, while the second clamp is mounted in the bore made in the slider.

 In FIG. 1 shows a longitudinal section of the proposed device.

 In FIG. 2 shows a plan view of the device.

 A device for cutting a titanium block consists of a bed 1 with guide planes 2, on which a slider 3 is mounted with the possibility of movement, a knife 4 fixedly mounted on the bed 1 over the entire width of the titanium block 5 and a receiving table 6, also fixedly mounted horizontally on the bed 1 equipped with a height adjustment mechanism 7.

 On the slider 3, a prismatic bearing surface 8 with teeth 9 is made, which serves as one of the clamps.

 In the bore 10 of the slider 3, a second clamp 11 with teeth 12 is installed, which has the ability to move along the cutting axis from the hydraulic cylinder 13. The main working hydraulic cylinder 14 is connected to the slider 3.

 The device operates as follows.

 Before starting the cutting, the device is in the initial position: the slider 3 is retracted to the extreme position from the knife 4, the receiving table 6 is set to the required cutting height, the clamp 11 is retracted from the prismatic bearing surface 8.

 The titanium block 5 is installed on the table 6 and pressurizes the clamp cylinder 3 and the main working cylinder 14. The clamp 11 presses the titanium block 5 against the prismatic bearing surface 8, ensuring its reliable clamping, and the slider 3 together with the clamped block 5 begins to move to the knife 4, pushes the block 5 onto the knife 4, removing chips across the entire width of the block in one pass.

 After the cut, the slider 3 of the hydraulic cylinder 14 returns to its original position, the clamp 11 of the hydraulic cylinder 13 is removed from the block, releasing it, while the block is lowered to the table 6.

 Next, the cycle repeats.

 The thickness "B" of the removed chips is regulated by high-altitude installation of the table 6 from the mechanism 7.

 When cutting, the chips are removed in one pass and are not scattered along the entire length of the cut, but are collected in one place in the box, while the device has only one direction of movement, which simplifies the design.
