Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting tool dies, in particular to a tool die with high surface precision. Background Technique

[0002] In the whole die-cutting process design, the design of the tool die is particularly important. Designers need to design corresponding tool dies according to the precision, material, and shape structure of the product. The tool dies designed by designers should be as suitable for die-cutting processing as possible, simple and reasonable, with high material utilization rate and low waste discharging difficulty. Especially for products with small holes, the die-cutting and waste discharging processes are very important. If not mastered well, it is very likely that the products cannot be made or waste will be caused. The purpose of developing refined tool dies is to give full play to the efficiency of the equipment, and also take into account the service life, cost of the tool die, and the difficulty and efficiency of tool setting, so as to reduce product waste and improve production efficiency.

[0003] Common tool dies all use laser tool dies. The blades are embedded in the wooden board for die-cutting production. Laser tool dies mainly use the strong energy of the laser to ablate a gap with high depth on the laser tool die board, and then install the blades into the gap to achieve the purpose of installing the blades. Laser tool dies have the characteristics of small error and high processing efficiency. However, the interface of the laser tool die is easily continuously etched by the laser, resulting in burrs and a decrease in precision. In existing production, there is also an etching tool die. It is formed by laminating a film with the etching tool die board for exposure, then developing and strengthening, and then corroding the redundant part with a corrosion machine. Finally, a milling machine is used to process the blade edge and surface treatment is carried out. The size precision of the etching tool die is very high, generally maintaining at ±0.03 mm, and the flatness of the cutting edge is maintained at about ±0.01. In the existing technology, most of the two tool dies are combined for use. After combination, the characteristics of high service life of the etching tool die and high processing precision of the laser tool die can be combined. However, most of the existing combination methods are through the inlay method, assembling the wooden laser tool die and the rigid etching tool die. However, the existing inlay method is generally difficult to disassemble, and it is difficult to discharge the debris in the laser tool die. In view of this, a tool die with high surface precision is now proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a new technical solution: a die with high surface precision, including a laser die 1, a discharge groove 2 is provided on the front surface of the laser die 1, and a blocking plate 3 is arranged in the discharge groove 2;

[0029] Among them, a disassembly and assembly device is arranged on the laser die 1, and the disassembly and assembly device includes an etching die 4, two insertion holes 5, two slide holes 6, two spring grooves 7, two fixed rods 8, two pull rings 9, two fixed blocks 10, two rings 11, two springs 12, two fixed columns 13 and two card slots 14.

[0030] Further, both jacks 5 are fixedly installed on the lower surface of the laser die 1. Two sliding holes 6 are respectively opened in the vertical plates on opposite sides of the laser die 1, and the two sliding holes 6 communicate with the two jacks 5;

[0031] Among them, both spring grooves 7 are opened in the vertical plates on opposite sides of the laser die 1, and the two spring grooves 7 communicate with the two sliding holes 6.

[0032] Further, two fixing rods 8 are respectively slidably sleeved in the inner walls of the two sliding holes 6. Two fixing blocks 10 are respectively fixedly installed at the opposite ends of the two fixing rods 8, and the lower surfaces of the two fixing blocks 10 are both arranged in an inclined plane;

[0033] Among them, two pull rings 9 are respectively fixedly installed at the opposite ends of the two fixing rods 8.

[0034] Further, two rings 11 are respectively fixedly sleeved on the outer surfaces of the two fixing rods 8. Two springs 12 are respectively fixedly installed on the opposite surfaces of the two rings 11, and the opposite ends of the two springs 12 are both fixedly installed on the inner walls of the spring grooves 7.

[0035] Further, the etching die 4 is arranged on the lower surface of the laser die 1;

[0036] Further, two fixing columns 13 are both fixedly installed on the upper surface of the etching die 4. Two clamping grooves 14 are respectively opened on the outer surfaces of the two fixing columns 13;

[0037] When the die cutter with high surface precision is in use, by inserting the two fixing posts 13 fixedly installed on the upper surface of the etched die cutter 4 into the two jacks 5 opened on the lower surface of the laser die cutter 1, at this time, the inclined surfaces of the two fixing posts 13 impact the inclined surfaces of the two fixing blocks 10, and the two fixing posts 13 exert opposite-direction thrusts on the two fixing blocks 10, causing them to move in opposite directions. At the same time, the two fixing blocks 10 exert opposite-direction thrusts on the two fixing rods 8 fixedly installed on the opposite sides, causing them to move in opposite directions in the two sliding holes 6. At the same time, the two fixing rods 8 drive the two rings 11 fixedly installed on the outer surface to move in opposite directions. While the two rings 11 move in opposite directions, they exert pressure on the two springs 12 fixedly installed on the opposite sides, causing them to contract. At this time, continuously insert the two fixing posts 13 into the two jacks 5. At this time, the two fixing blocks 10 pass through the two card slots 14 opened on the outer surface of the two fixing posts 13. At this time, the two fixing blocks 10 are no longer subjected to the extrusion force of the two fixing posts 13, and at the same time, the two springs 12 are no longer stressed. The two springs 12 expand. At the same time, the two springs 12 exert a thrust on the two rings 11 fixedly connected to the opposite sides, causing the two rings 11 to drive the two fixing rods 8 fixedly installed on the inner surface to move towards the opposite sides. At the same time, the two fixing rods 8 exert opposite-direction thrusts on the two fixing blocks 10 fixedly installed on the opposite sides, causing them to move towards the opposite sides and be clamped into the two card slots 14 opened on the outer surface of the two fixing posts 13 for fixation. In daily use, the blocking plate 3 in the discharge chute 2 can be pulled out manually, and the processing waste chips in the laser die cutter 1 can be discharged by shaking;

[0038] For the die cutter with high surface precision, the etched die cutter embedded in the laser die cutter can be fixed, and the disassembly and assembly are convenient after fixation. The laser die cutter with a lower service life can be disassembled and replaced. After replacement, die cutting can continue on the etched die cutter. Since the combined die cutter has an etched die cutter, the etched die cutter can be used in places where high precision requirements for product dimensions are required to prevent problems such as continuous interfaces caused by using a laser knife, that is, burrs are avoided, the engraving precision is improved, and it also has the characteristics of a high service life. Moreover, for the die cutter with high surface precision, the laser die cutter and the etched die cutter are connected by a clamping method. Compared with the traditional forward method, this method is more stable in fixation, and the bottom of the laser die cutter can be cleaned by disassembly, further improving the engraving precision.

[0039] Working principle: When using the die with high surface precision, two fixing columns 13 fixedly installed on the upper surface of the etched die 4 are inserted into two jacks 5 opened on the lower surface of the laser die 1. At this time, the inclined surfaces of the two fixing columns 13 impact the inclined surfaces of the two fixing blocks 10, and the two fixing columns 13 apply opposite-direction thrusts to the two fixing blocks 10, causing them to move in opposite directions. At the same time, the two fixing blocks 10 apply opposite-direction thrusts to two fixing rods 8 fixedly installed on the opposite sides, causing them to move in opposite directions in the two sliding holes 6. At the same time, the two fixing rods 8 drive two rings 11 fixedly installed on their outer surfaces to move in opposite directions. While the two rings 11 are moving in opposite directions, they apply pressure to two springs 12 fixedly installed on the opposite sides, causing them to contract. At this time, continuously insert the two fixing columns 13 into the two jacks 5. At this time, the two fixing blocks 10 pass through two card slots 14 opened on the outer surface of the two fixing columns 13. At this time, the two fixing blocks 10 are no longer subjected to the extrusion force of the two fixing columns 13, and at the same time, the two springs 12 are no longer stressed and expand. At the same time, the two springs 12 apply thrusts to the two rings 11 fixedly connected to the opposite sides, causing the two rings 11 to drive two fixing rods 8 fixedly installed on their inner surfaces to move towards the opposite sides. At the same time, the two fixing rods 8 apply opposite-direction thrusts to the two fixing blocks 10 fixedly installed on the opposite sides, causing them to move towards the opposite sides and be snapped into two card slots 14 opened on the outer surface of the two fixing columns 13 for fixation. In daily use, the blocking plate 3 in the discharge chute 2 can be pulled out manually, and the processing waste chips in the laser die 1 can be discharged by shaking.
