A forming tool rework tooling

Abstract

The invention provides a forming cutter reworking tool, consisting of cutter rests, cutters, pressing blocks and a diamond grinding wheel, wherein a plurality of lined-up cutter placement faces are arranged in an array way on one side of the cutter rests; a plurality of lined-up pressing block grooves are arranged in an array way on the other side of the cutter rests; each cutter placement face corresponds to one pressing block groove; a threaded hole is formed in each pressing block groove; the pressing blocks are arranged on the cutter placement faces and the pressing block grooves; the pressing blocks pass through annual groove holes in the centers of the pressing blocks through bolts and are fixed with the threaded holes in the pressing block grooves in a matching way in the purpose of fixedly assembling the cutters in the cutter placement faces; when the cutters are assembled in the cutter placement faces, the front cutter faces of the cutters and the upper end faces of the cutter rests are all kept horizontal; chip grooves in the cutters and the tangent planes of front cutter faces are kept horizontal as well; when all the cutters are assembled in the cutter placement faces, the diamond grinding wheel makes linear motion along the front cutter faces of the cutters and in a way of leaning on the chip grooves. The forming cutter reworking tool has the beneficial effects of simple structure, low cost and improvement in reworking precision and efficiency.

Description

technical field [0001] The invention relates to the field of repairing tools, in particular to a tool for repairing forming tools. Background technique [0002] At present, the main problems of reworked tools are as follows: 1. The service life of the reworked tool is short, and problems such as chipping, pattern, notch, and poor chip removal occur prematurely, and the reworked tool cannot be used for larger tools; There are differences between new knives. According to the on-site investigation and the introduction of the tool reworker, it is found that the current factors affecting the service life of the reworked tool are: a. Incorrect selection of coolant: when the diamond grinding wheel grinds the reworked tool, a large number of small ceramic metal particles are brought out from the surface of the tool. These particles are hard, and if they cannot be taken away in time, it will have a very bad impact on the subsequent grinding; according to the survey, the coolant used...

Problems solved by technology

[0002] At present, the main problems of reworked tools are as follows: 1. The service life of the reworked tool is short, and problems such as chipping, pattern, notch, and poor chip removal occur prematurely, and the reworked tool cannot be used for larger tools; There are differences between the new knives

[0004] There are two main reasons for the unqualified parameters: (1) The tool grinder does not know the specific geometric parameters of each tool. Since he does not know the specific parameters, the grinder can only roughly Putting out the above-mentioned machine angle, grinding wheel angle, and rotation angle, as for whether it is correct or not, there is no verification; (2) It is difficult to set the tool. At present, it mainly depends on the universal vise on the tool grinder to swing the angle of the vise and adjust the angle. Depending on the adjustment of the adjusting bolt, the accuracy is poor

[0005] In terms of efficiency, there are two main factors that restrict the efficiency of rework: (1) It takes a long time to adjust the tool: every time the tool grinder changes the model, he needs to adjust three parameters, and each parameter is an estimated value It is inevitable that the tool setting will be inaccurate, and such reciprocating adjustments will consume a lot of time; (2) Due to the limitation of the existing tooling tooling, only one tool can be repaired at a time

[0006] At present, the tooling that can repair multiple tools at the same time without adjusting the tool setting faces many technical problems: First, it is impossible to take into account the three angles of the tool's rotation angle, grinding wheel angle, and machine angle at the same time. For example, the machine angle of the tool is 4°, If the tool placement surface is rotated by 4°, so that the machine angle of the first knife is horizontal, the subsequent blades will follow up; secondly, the angle of the tool placement surface rotated by three angles is difficult to calculate
