Description

Technical Field

[0001] The invention belongs to the technical field related to mold processing, and in particular relates to a wire cutting device used for mold processing. Background Art

[0002] During the production and processing of molds, cutting equipment is needed to cut the raw materials. There are many cutting equipment on the market now, and most of the cutting equipment used in mold production and processing is wire cutting equipment. Since some molds now have high precision requirements and complex structures, some wire cutting cannot stably complete the processing of some complex high-precision molds as a whole, so some wire cutting equipment that can complete the processing with high precision has emerged.

[0003] For example, patent application number CN202020401357.1 discloses a wire cutting device for mold processing, comprising a bearing box, a bearing support rod is arranged on the base surface of the bearing box and on the right side of a water pump mounting seat, a positioning mounting rod is arranged on the upper left side of the bearing support rod, a high-pressure nozzle is arranged on the right side of the positioning mounting rod, a first adjusting mechanism is arranged on the right side of the base surface of the bearing box, a second adjusting mechanism is arranged on the upper side of the first adjusting mechanism, and a loading platform is arranged on the upper side of the bearing top plate. The mold to be cut can be positioned by the cooperation of the first adjusting mechanism and the second adjusting mechanism, and timely response can be made if displacement occurs during the cutting process, and the first adjusting mechanism and the second adjusting mechanism can be regulated manually and electrically, which is simple and convenient. The first adjusting mechanism and the second adjusting mechanism cooperate with the high-pressure nozzle to accurately cut the mold and improve the quality of mold cutting.

[0004] In the prior art, precise cutting of the mold is achieved through multiple adjustment mechanisms, which improves the cutting quality. However, there are still certain deficiencies during use: most of the existing cutting wires are still pulled at the upper and lower ends. Although protection is set above the bottom traction in the prior art, the mold density is relatively large, and the fragments dropped after cutting will still cause vibration to the bottom traction, causing the cutting wire to loosen, resulting in changes in the wire cutting positioning data and loss of the reference position, affecting the cutting accuracy and production efficiency. Summary of the invention

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0030] refer to Figure 1-10 A wire cutting device for mold processing includes an operating table 71 and a base 75. The base 75 is arranged on the end surface of the operating table 71, and a sliding plate 74 is slidably arranged above the base 75. A discharge cylinder 76 is arranged on the end surface of the sliding plate 74, and a wire releaser 79 is arranged on the top of the discharge cylinder 76. A protective cylinder 77 is arranged on the end surface of the base 75 below the wire releaser 79, and a connecting seat 81 is arranged in the protective cylinder 77. The cutting wire is connected between the connecting seat 81 and the wire releaser 79, and a tensioning assembly is arranged on one side of the cutting wire at the bottom of the sliding plate 74, and a hole plate 87 is arranged on the top of the protective cylinder 77 above the connecting seat 81. A plurality of balls 88 are rotatably arranged on the end surface of the hole plate 87, and a plurality of water spray pipes 85 are arranged on the conical surface of the protective cylinder 77 outside the ball 88. A water absorption ring seat 83 is connected to the bottom of the protective cylinder 77 below the water spray pipe 85, and a buffer pad 84 is arranged outside the water spray pipe 85.

[0031] A fence is set on the outer end face of the operating table 71, and the inside can be filled with coolant for rapid cooling. The staff can place a tooling structure for clamping and moving the mold on the end face of the operating table 71, so that the mold can move stably outside the cutting line, so that the cutting line can complete the cutting. Before cutting, the staff can drive the sliding plate 74 upward to move and drive the wire releaser 79 to release part of the cutting line, so that the equipment can complete the cutting processing of molds at different heights. In this relationship, the bottom of the mold can be fitted on the end face of the hole plate 87 and move. The multiple ball bearings 88 on the end face of the hole plate 87 will contact and roll with the bottom of the mold during this process, so that the mold can move smoothly. This setting can quickly determine the cutting reference point, so that the height between the mold and the connecting seat 81 will not be too high, reducing cutting resistance and improving cutting efficiency.

[0032] When the mold is placed, the tensioning assembly will tension the cutting line to ensure that the cutting line remains taut and the cutting effect is guaranteed. Then the connecting seat 81 is energized to complete the cutting process. During the cutting process, the water absorption ring seat 83 can absorb the coolant in the operating table 71, and then spray it onto the hole plate 87 and the cutting line through the water spray pipe 85, so that the cutting position of the mold can be quickly cooled. In this relationship, since the hole plate 87 has a positioning function, the water spray pipe 85 can better cool the cutting point while also flushing away waste chips and dirt, thereby improving the cleaning effect.

[0033] When the cut block falls, the buffer pad 84 will provide protective shock absorption for the protective tube 77 to avoid damage to the components inside the protective tube 77 and improve cutting safety. In this regard, the top of the protective tube 77 is conical, which can facilitate the block to roll down quickly and reduce impact. At the same time, the water spray from the water pipe 85 can also wash the fallen block to one side, reducing the possibility of it falling directly onto the protective tube 77.

[0034] refer to Figure 7 Each water spray pipe 85 is provided with an arc-shaped pipe head 86 made of flexible material at the top.

[0035] The arc-shaped pipe head 86 is made of elastic material, is bent inward as a whole, and has a hole in the middle, which can effectively prevent waste and dirt from accumulating at the end of the water spray pipe 85 and prevent the water spray pipe 85 from being blocked.

[0036] refer to Figure 8 A support plate 89 is provided in the end surface of the base 75 below the protective tube 77. The support plate 89 and the bottom of the protective tube 77 are connected to each other through a plurality of connectors 90. A plurality of buffer pads 93 are provided on the end surface of the support plate 89.

[0037] The support plate 89 can be connected to the bottom of the protective tube 77 through the connecting piece 90, so as to support and fix the protective tube 77. The buffer pad 93 is made of elastic material and is attached to the end surface of the protective tube 77 over a large area. It can effectively absorb the impact of blocks falling onto the protective tube 77 and ensure safety during wire cutting.

[0038] refer to Figure 9-10 The tensioning assembly includes a telescopic seat 78 arranged below the sliding plate 74, a piston plate 96 is slidably arranged in the telescopic seat 78, and two connecting plates 49 are arranged on the end surface of the piston plate 96 close to the discharge barrel 76. One end of the two connecting plates 49 extends out of the end surface of the telescopic seat 78, and a pressing roller 82 is rotatably connected to the end of the connecting plate 49 extending out of the telescopic seat 78, and the outer cylindrical surface of the pressing roller 82 abuts against the cutting line.

[0039] When the cutting line needs to be tightened, the telescopic seat 78 can push the internal piston plate 96 to move toward the room away from the discharge barrel 76, thereby pushing the connecting plate 49 at one end of the piston plate 96 to retract inward, thereby pulling the pressing roller 82 to abut against the outside of the cutting line, thereby pulling the top of the cutting line to move inward, so that the cutting line can be tightened.

[0040] refer to Fig. 9 The tensioning assembly also includes a spring 95 disposed between the piston plate 96 and the telescopic seat 78 , and a vent 99 is disposed at the bottom of the telescopic seat 78 below the spring 95 .

[0041] The spring 95 can push the piston plate 96 to move in the direction away from the discharge barrel 76, so that the lamination roller 82 will abut against the outside of the cutting line when no power is supplied, and perform elastic tensioning. When the cutting line does not need to be tensioned, the vent 99 will draw air inward, so that the piston plate 96 moves toward the discharge barrel 76. At this time, the lamination roller 82 will move away from the cutting line and exit the tensioning state.

[0042] refer to Fig. 9 The tensioning assembly also includes a plurality of elastic rods 97 arranged between the telescopic seat 78 and the bottom of the sliding plate 74.

[0043] The elastic rod 97 is made of an elastic metal material and can absorb the vibration transmitted from the cutting line to the telescopic seat 78, so that the telescopic seat 78 can stably complete the tensioning process.

[0044] refer to Figure 4 , 9 -10, a connecting tube 94 is provided at the bottom of the discharge barrel 76, a plurality of limiting rings 98 are provided in the connecting tube 94, and a discharger 80 is provided above the limiting rings 98 at the bottom of the discharge barrel 76.

[0045] The discharger 80 can energize the cutting line. When the cutting line is released or retracted, it must pass through the connecting tube 94. When the cutting line is tensioned, the cutting line will also abut against the limiting ring 98. The limiting ring 98 is made of elastic material and can elastically support the cutting line, so that the vibration transmitted to the cutting line during cutting can be absorbed by the limiting ring 98, thereby improving the cutting quality.

[0046] refer to Figure 1-3 A bracket 72 is provided on one end surface of the base 75 , a push cylinder 73 is provided on the end surface of the bracket 72 , and an output end of the push cylinder 73 is connected to the end surface of the sliding plate 74 .

[0047] When the cutting line needs to be lengthened or shortened, the output end of the push cylinder 73 can drive the sliding plate 74 to move up and down, thereby driving the discharge barrel 76 to move up and down, so that the cutting line can be retracted and released. Embodiment 2:

[0048] On the basis of or different from the first embodiment, reference Figure 8 A plurality of hard pads 91 are arranged on the end surface of the support plate 89 in the buffer pad 2 93 .

[0049] The hard pad 91 is made of a hard metal material and can provide rigid support to the bottom of the protective tube 77 , thereby increasing the support strength of the protective tube 77 and improving the processing effect. Embodiment three:

[0050] On the basis of or different from the first embodiment, reference Figure 7 A plurality of filter valve ports 92 are provided on the outer circumferential surface of the water absorption ring seat 83 .

[0051] The filter valve port 92 can filter the coolant entering the water suction ring seat 83 to remove waste debris, thereby ensuring the stable operation of the water spray pipe 85 and the water suction ring seat 83 .
