Abstract
Description
Technical Field
[0001] This utility model relates to the field of die casting technology, and in particular to a sawing tool retraction device. Background Technology
[0002] A vertical saw is a cutting device with a vertical layout that uses a ring-shaped saw blade to cut straight lines, curves, and angles in metal or non-metal materials.
[0003] However, the current problem is that ordinary vertical saws are prone to the saw blade falling off when sawing some products with special structures. The sawing direction of the gate of some die-cast products has product characteristics and cannot be sawed in a completely straight line. It needs to be retracted halfway through the sawing. During the retraction process, due to the burrs and other structures on the sawing surface, the saw blade will fall off after multiple processing. Therefore, there is a need for improvement. Utility Model Content
[0004] This utility model provides a sawing tool retraction device that can saw some special product features, effectively prevent the saw blade from falling off during retraction, ensure production continuity, and realize automated production. It solves the technical problem in the existing technology that the current sawing machine has a simple structure, which easily leads to the saw blade falling off during retraction when sawing special products, resulting in production interruption and inability to continue production.
[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a sawing fixture retraction device includes a vertical saw, a saw blade for removing excess features of the product, a material bed that can move laterally on the front side of the saw, a product fixed on a flip plate on the material bed, a flipping mechanism for turning the product between the flip plate and the material bed, and a retraction mechanism on the material bed that works in conjunction with the flipping mechanism. The retraction mechanism can move the product away from the saw blade after sawing. During sawing, the material bed moves the product laterally, and the flipping mechanism turns the product at a different angle, working with the saw blade to cut the excess features of the product. After the excess features of the product are cut, the retraction begins. Before retraction, the retraction mechanism moves the product away from the saw blade by 5-10mm. During the movement, the gear will not disengage from the rack, and the product will completely disengage from the saw blade after movement. When retraction is performed, the product will not pull the saw blade away; otherwise, the saw blade would fall off during retraction due to burrs on the cut surface of the product. This utility model can ensure the continuity of production.
[0006] Preferably, the flipping mechanism includes a rotating shaft installed at the bottom of the flip plate, with several gears sleeved on the rotating shaft. Several racks on the material bed mesh with the gears, and the racks move laterally to flip the flip plate. During the sawing process, the material bed moves the product laterally, while the racks move laterally to adjust the rotating shaft and the product's flipping angle, working in conjunction with the saw blade to cut off any excess features of the product.
[0007] Preferably, the rack in the tilting mechanism is driven by a hydraulic cylinder, pneumatic cylinder, or electric motor. The rack in the tilting mechanism can be driven by one of these methods; this invention will use hydraulic cylinder as an example for illustration.
[0008] Preferably, the ejection mechanism includes a drive mounted on one side of the rotating shaft, which can drive the entire rotating shaft structure to move back and forth. Before the blade is retracted, the ejection device drives the rotating shaft and the entire product structure to move 5-10mm away from the saw blade. During the movement, the gear will not disengage from the rack, and the product will completely detach from the saw blade after the movement. When the blade is retracted, the product will not pull the saw blade away. Otherwise, the burrs on the cut surface of the product would cause the saw blade to fall off during the retraction. This invention can ensure the continuity of production.
[0009] Preferably, the drive is a hydraulic cylinder, pneumatic cylinder, or electric motor drive. The drive in the unloading mechanism can be one of the following: hydraulic cylinder, pneumatic cylinder, hydraulic cylinder, or electric motor drive. This utility model uses a hydraulic cylinder drive as an example for explanation.
[0010] Preferably, the saw is equipped with a positioning detection device for detecting the sawing position of the product. During the sawing process, the material bed moves the product laterally, and the rack moves laterally, causing the shaft to rotate and the product to flip. This, in conjunction with the saw blade, saws off any excess features of the product. When the product is cut and flipped to a specific angle, the detection device sends a signal to start retracting the blade to prevent it from cutting the product.
[0011] Therefore, the sawing fixture retraction device of this utility model has the following advantages: it can saw some special product features, and by pushing the product horizontally during retraction, it can effectively prevent the saw blade from falling off during retraction, ensuring the continuity of production and realizing automated production.

[0018] In the diagram, there is a saw 1, a saw blade 2, a material bed 3, a flip plate 4, a rotating shaft 5, a gear 6, and a rack 7. Detailed Implementation
[0019] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0020] Example:
[0021] like Figure 1 and 2 As shown in Figures 3, 4, 5, and 6, a sawing fixture retraction device includes a vertical saw 1, on which a saw blade 2 for removing excess features from the product is mounted, and a material bed 3 that can move laterally is mounted on the front side of the saw 1. The material bed 3 is driven by a hydraulic cylinder, and the product is fixedly mounted on a flip plate 4 on the material bed 3.
[0022] The saw 1 is equipped with a positioning monitoring device for detecting the sawing position of the product.
[0023] A flipping mechanism for driving the product to flip is installed between the flip plate 4 and the material bed 3. The flipping mechanism includes a rotating shaft 5 fixedly installed at the bottom of the flip plate 4. Two gears 6 are installed on the outer sleeve of the rotating shaft 5. Two gears 6 are installed on the material bed 3, and the racks 7 mesh with each other. The racks 7 move laterally to drive the flip plate 4 and the product to flip at an angle.
[0024] The rack 7 in the material turning mechanism is driven by a hydraulic cylinder to move laterally and reciprocally.
[0025] The material bed 3 is equipped with a material ejection mechanism that works in conjunction with the material turning mechanism. The material ejection mechanism can move the product away from the saw blade 2 after sawing is completed.
[0026] The unloading and boxing process includes a drive installed on one side of the solder mask. The drive is a hydraulic cylinder, which can drive the rotating shaft 5 and the entire product to move back and forth.
[0027] During the sawing process, the material bed 3 drives the product to move laterally, while the rack 7 moves laterally, driving the shaft 5 and the product to rotate at an angle. Together with the saw blade 2, it saws off excess features of the product. When the product is cut and rotated to a specific angle, the detection device sends a signal to start retracting the blade to prevent the product from being sawn.
[0028] Before the blade retraction, the hydraulic cylinder of the ejector device drives the rotating shaft 5 and the overall product structure to move 5-10mm away from the saw blade 2. During the movement, the gear 6 will not disengage from the rack 7. After the product moves, it will completely separate from the saw blade 2. When the blade retraction is performed, the product will not pull the saw blade 2 away. Otherwise, the burrs on the cut surface of the product will cause the saw blade 2 to fall off during the retraction. This utility model can ensure the continuity of production.
[0029] The drive control in this invention is all driven by hydraulic cylinders. The sequential control oil circuit is designed according to actual requirements, which facilitates adjustment and control.
