Description

Technical Field

[0001] This utility model relates to the technical field of tungsten wire drawing equipment, specifically an electric heating oven with a mold frame. Background Technology

[0002] Tungsten wire, due to its high mechanical strength, excellent fatigue resistance, and corrosion resistance, is used in the production of diamond wire. Diamond wire made from tungsten wire can achieve smaller diameters, which is of great significance to the photovoltaic industry. Currently, tungsten wire used in industrial production is usually produced by multiple rounds of drawing using a wire drawing machine. During the drawing process, the tungsten wire needs to be heated to facilitate drawing. Drawing involves extruding coarse-diameter tungsten wires layer by layer using a die to gradually compress them into micrometer-sized wires. For example, Chinese utility model patent CN221018022U discloses a tungsten wire drawing heating device, including an open box containing a heating wire. Grooves are installed on both sides of the open box, with corresponding wire-passing grooves on the two grooves. The open box is mounted at the front end of a mounting frame, and a sliding mechanism facing the open box is located at the rear end of the mounting frame. The sliding mechanism is connected to a heat-insulating cover, and the opening and closing of the heat-insulating cover cooperates with the open box. However, current tungsten wire drawing ovens have the following drawbacks:

[0003] Currently, the wire drawing die is installed inside the mold base of the housing. Replacing the wire drawing die is inconvenient, and long-term use will also cause damage to the mold base and the wire drawing die installation point, resulting in economic losses.

[0004] Therefore, we propose an electric heating oven with a mold frame to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric heating oven with a mold frame to solve the problems mentioned in the background art.

[0009] Preferably, the end of the protective cover near the mounting plate has an open structure, a second strip plate is fixed to the side of the protective cover near the mounting plate, and a first strip plate is fixed to the open side of the protective cover away from the mounting plate. The first strip plate is fixed to the edge of the box with screws, and the second strip plate is fixed to the mounting plate with screws.

[0010] Preferably, the lid has a groove on the side near the box body, and a mica plate is fixed to the groove by screws. Two hinges are fixed between the end of the lid and the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The mold frame of this utility model is used to support the wire drawing die, which is installed on the toothed opening. This makes it easier to replace the wire drawing die. After long-term use, the damage will only appear on the mold frame, so the mold frame can be replaced, reducing the economic losses caused by wear.

[0022] Example 2:

[0023] Please see Figure 1-4 This is the second embodiment of the present invention. Based on the previous embodiment, a mounting plate 13 is fixedly connected to one end of the housing 1, and a heat insulation plate 14 is fixedly connected to the side wall of the mounting plate 13. Seven electric heating rod mounting holes 15 are horizontally opened at the end of the housing 1 near the mounting plate 13. A thermocouple mounting hole 16 is also opened at the end of the housing 1 near the mounting plate 13. The electric heating rod mounting holes 15 are used to install electric heating rods, and the thermocouple mounting holes 16 are used to install thermocouples. Electric heating is adopted. Traditional tungsten wire drawing uses industrial gas heating, which requires high safety requirements. The use of electric heating reduces the safety requirements of the equipment.

[0024] The outer wall of the housing 1 is fitted with a protective cover 4. The protective cover 4 has an open structure on the side near the housing 1. Multiple sawtooth-shaped openings 42 are provided on the top and bottom edges of the opening side of the protective cover 4, corresponding to multiple wire feeding grooves 12. A heat insulation cotton layer 41 is fixed to the inner side of the protective cover 4. Tungsten wires can be easily inserted into the sawtooth openings 42.

[0025] The protective cover 4 has an open structure at one end near the mounting plate 13. The second strip plate 44 is fixed to the side of the protective cover 4 near the mounting plate 13. The first strip plate 43 is fixed to the open side of the protective cover 4 away from the mounting plate 13. The first strip plate 43 is fixed to the edge of the housing 1 by screws. The second strip plate 44 is fixed to the mounting plate 13 by screws.

[0026] The lid 2 has a groove 21 on the side near the body 1. A mica plate 22 is fixed to the groove 21 by screws. Two hinges 23 are fixed between the end of the lid 2 and the mounting plate 13.

[0027] The mounting plate 13 has multiple first strip holes 17 at the ends of the multiple electric heating rod mounting holes 15, and the heat insulation plate 14 has multiple second strip holes 18 at the positions of the multiple first strip holes 17. The mounting plate 13 has a first through hole 19 at the position of the thermocouple mounting hole 16, and the heat insulation plate 14 has a second through hole 110 at the position of the first through hole 19. Electric heating rods can be directly inserted and installed at the positions of the first strip holes 17 and the second strip holes 18, and thermocouples can be directly inserted and installed at the positions of the first through holes 19 and the second through holes 110.

[0028] In use, the drawing die is installed at the toothed opening 31, and the entire assembly is mounted on the large frame via the mounting plate 13 and the heat insulation plate 14. Then, the electric heating rod is installed at the electric heating rod mounting hole 15 from the side, and the thermocouple is installed at the thermocouple mounting hole 16. The machine can then be turned on to check if it is working properly. During operation, the tungsten wire enters the oven through the serrated opening 42 and the wire feeding groove 12, is squeezed by the drawing die mounted on the die frame 3, and is then pulled out from the serrated opening 42 on the other side. The die frame 3 in this invention is used to support the drawing die, which is mounted on the toothed opening 31. This makes die replacement more convenient. After prolonged use, damage will only occur on the die frame 3, requiring only die frame 3 replacement, thus reducing economic losses due to wear and tear. This invention uses electric heating, whereas traditional tungsten wire drawing uses industrial gas heating, which requires higher safety standards. Electric heating lowers the safety requirements of the equipment.
