Description
Technical Field
[0001] The invention relates to the technical field of sawing machines, in particular to a vertical band sawing machine. Background Art
[0002] The vertical band saw is a cutting device widely used in the metal, wood, plastic and other material processing industries. Its notable feature is that the saw blade is perpendicular to the work surface, and the workpiece is moved under the saw blade by clamping or manually pushing, so as to achieve cutting of various shapes. Compared with traditional manual cutting tools, the vertical band saw has higher precision and efficiency, so it is widely used in modern manufacturing and processing. The original intention of the design of the vertical band saw is to solve the complex cutting needs of various shapes. Compared with the horizontal band saw, the vertical band saw is more suitable for curve and special-shaped cutting, as well as processing of materials of different sizes and thicknesses due to its vertical saw blade design. The vertical band saw can be installed with various saw blades, and different saw tooth specifications can be selected according to the hardness and density of the cutting material to meet a variety of processing needs. This type of equipment is also of high precision, especially suitable for scenes such as precision mold manufacturing and curve cutting, which can significantly improve processing accuracy and process effects; There are still the following defects in specific use: 1. Vibration ripples will cause the saw blade's cutting path to deviate, making the cutting uneven and difficult to obtain a smooth cutting surface. This irregular vibration will cause dimensional deviation and affect the precision of the finished product, especially in the processing of parts that require high precision. The cutting effect does not meet the requirements. Secondly, vibration ripples will form irregular bumps on the cutting surface, making the surface rough and uneven. The rough surface not only affects the appearance, but also requires more finishing treatment in subsequent processing (such as polishing and welding), which increases the additional processing cost.
[0003] 2. In addition, overheating can cause local softening of the material, making the cutting surface rough and uneven, with slag or irregular texture, which reduces the surface quality of the workpiece. The rough surface does not meet the requirements of precision machining and will affect the appearance and functionality of the finished product. At the same time, overheating can cause thermal expansion and deformation of the material, especially on heat-sensitive materials or thin plate materials. This deformation may lead to inaccurate cutting dimensions. For some parts with high precision requirements, thermal deformation will lead to dimensional deviation, and ultimately the workpiece will not meet the design requirements.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can accelerate the cutting process by moving the cutting piece, which can make the cutting piece actively generate friction with the saw belt, which helps to shorten the cutting time and improve production efficiency, especially when high-speed cutting is required; the addition of the moving cutting piece can stabilize the position of the saw belt during the cutting process, and by controlling the moving trajectory of the cutting piece, it can help maintain the cutting direction of the saw belt; when the cutting piece moves, it can disperse the cutting force, so that the force exerted by the saw belt on the material is more uniform. This uniform cutting force can reduce the ripples and roughness of the cutting surface, improve the quality of the cutting surface, and reduce subsequent processing steps; moderate moving friction makes the cutting piece more evenly stressed, thereby reducing local wear of the saw belt. This can extend the service life of the saw belt, reduce the replacement frequency and maintenance costs; by moving the cutting piece, regular friction can be generated between the saw belt and the material, which helps to discharge the chips from the cutting area, keep the cutting area clean, and avoid cutting resistance caused by chip accumulation.
[0018] (2) The present invention can offset the cutting vibration of the saw belt by introducing high-frequency and micro-amplitude vibrations, thereby offsetting some irregular vibrations. This can better balance the feed force, reduce irregular ripples, and make the cutting surface smoother; the vibration offset mechanism can form a slight alternating impact force between the saw belt and the workpiece surface, making the cut more uniform, which will make the surface texture more delicate and reduce the subsequent surface finishing; the introduction of offset vibration can reduce the pressure in a single direction during the cutting process, making the wear distribution of the saw belt more uniform. This can avoid excessive wear in certain parts, increase the tool life, and maintain the stability of the cutting effect; during the cutting process, workpieces of different materials may produce cutting force fluctuations. The vibration offset mechanism can automatically adapt to these fluctuations through the action of micro-vibration, balance the feed force, and thus maintain the stability of the cutting force.
[0019] (3) The temperature control balancing mechanism of the present invention can temporarily reduce the friction pressure of the saw belt during the cutting process by intermittently clamping and releasing the saw belt, so that the friction between the saw belt and the workpiece can be controlled in a time-sharing manner. This dynamic clamping method allows the saw belt to obtain a short cooling time at a certain interval, avoiding excessive heat generated by the saw belt and the workpiece due to long-term continuous contact, and reducing heat accumulation; the temperature control balancing mechanism reduces heat accumulation during cutting, reduces the temperature change frequency of the saw belt, reduces the impact of thermal expansion on the saw belt, extends the service life of the saw belt, and reduces the cost of frequent replacement of the saw belt; the temperature control balancing mechanism reduces heat deformation while reducing heat accumulation, making the cutting process more stable, thereby obtaining a higher quality cutting surface and improving the finished product accuracy of the workpiece; the temperature control balancing mechanism is equivalent to providing the saw belt with a short cooling "rest" time during the cutting process. This intermittent cooling has a positive effect on protecting the saw belt and the saw wheel, avoiding material fatigue and equipment damage caused by high temperature. At the same time, this method reduces the load of the motor and reduces the heat accumulation of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] refer to Figure 7 As shown, the temperature control balance mechanism 4 is used to provide additional support to reduce local overheating of the material; refer to Figure 7 As shown, the temperature control balance mechanism 4 includes an external plate 41 fixedly connected to the outer wall of one side of the circular plate 211, and an obstacle column 42 is fixedly connected to the outer wall of one end of the external plate 41 away from the circular plate 211, and a bottom block 43 is arranged below the obstacle column 42, and a support plate 44 is fixedly connected to the inner wall of one side of the bottom block 43, and an upper clamping plate 45 is rotatably connected to the outer wall of one end of the support plate 44 away from the bottom block 43, and a lower support column 46 is fixedly connected to the outer wall of the upper clamping plate 45 away from the support plate 44, and the upper clamping plate A lower spring telescopic rod 47 is fixedly connected to the outer wall of one side of 45 close to the lower support column 46, and two lower spring telescopic rods 47 are symmetrically arranged with the central axis of the support plate 44.

This dynamic clamping method allows the saw band 12 to obtain a short cooling time at a certain interval, avoiding excessive heat generated by the saw band 12 and the workpiece due to long-term continuous contact, and reducing heat accumulation; the temperature control balance mechanism 4 reduces heat accumulation during cutting, reduces the frequency of temperature changes of the saw band 12, reduces the impact of thermal expansion on the saw band 12, extends the service life of the saw band 12, and reduces the cost of frequent replacement of the saw band 12; the temperature control balance mechanism 4 reduces heat deformation while reducing heat accumulation, making the cutting process more stable, thereby obtaining a higher quality cutting surface and improving the finished product accuracy of the workpiece; the temperature control balance mechanism 4 is equivalent to providing a short cooling "rest" time for the saw band 12 during the cutting process. This intermittent cooling has a positive effect on protecting the saw band 12 and the saw wheel 11, avoiding material fatigue and equipment damage caused by high temperature. At the same time, this approach reduces the load on the motor 14 and reduces the heat accumulation of the motor 14 .
[0025] The complete working principle and steps of the above embodiment are as follows: Initial Limitation: 1. Preparation Phase First, according to the material, size and cutting requirements of the workpiece, the operator makes settings adjustments on the band saw machine body 1. This includes the adjustment of the workpiece clamping device 13 and the control of the tension of the saw band 12. Selecting the type and tooth shape of the saw band 12 suitable for the cutting task ensures that the saw band 12 can withstand the cutting pressure and provide the best cutting effect.
[0026] 2. Workpiece clamping and feeding Before the saw band 12 is started, the operator places the workpiece on the workpiece clamping device 13. The workpiece clamping device 13 ensures that the workpiece is fixed by a mechanical, hydraulic or pneumatic system to prevent sliding or tilting during cutting. For larger and heavier workpieces, the workpiece clamping device 13 provides more stable support to ensure cutting quality. At this time, the feed mechanism will push the workpiece toward the saw band 12 according to the set feed speed to ensure that the workpiece contacts the saw band 12 at a stable rate.
[0027] 3. Start-up and operation of saw band 12 As the motor 14 is started, power is transmitted to the saw wheel 11, causing it to rotate and drive the saw band 12 to run in a fixed direction. The saw band 12 performs a circular motion around the saw wheel 11, forming a continuous cutting force. According to the set speed and the pitch of the saw band 12, the saw band 12 contacts the workpiece at an appropriate feed rate and starts cutting.
[0028] When the saw belt 12 is running at high speed, the teeth gradually cut into the surface of the workpiece. The teeth grind the material at alternating angles and speeds during the cutting process to form a smooth cutting path. Since the tooth shape of the saw belt 12 is precisely designed, the cutting in and out of each tooth during the cutting process is relatively uniform, thereby reducing the surface roughness of the workpiece and ensuring the cutting quality.
[0029] 4. Cooling and lubrication During the cutting process, the friction between the saw band 12 and the workpiece generates a lot of heat. In order to prevent the saw band 12 from overheating, resulting in a decrease in cutting efficiency, or even deformation or damage of the saw band 12, the cooling system is activated. Coolant or lubricant is delivered to the contact area between the saw band 12 and the workpiece to reduce the accumulation of frictional heat and take away some of the chips, thereby ensuring the stability of the saw band 12 for a long time. The coolant can also improve the quality of the cut surface to a certain extent, making it smoother.
[0030] 5. Guiding and Control of Saw Band 12 The guide device on the band saw machine body 1 plays a key role in helping the saw band 12 to run within the predetermined track. The guide device is located on both sides of the saw wheel 11 to ensure that the saw band 12 does not deviate when subjected to cutting pressure. The guide system works in conjunction with the workpiece clamping device 13 and the feed system to keep the workpiece stable during the cutting process and ensure the accuracy of the cutting line.
[0031] 6. Feed control and speed adjustment The feed system continuously adjusts the feed rate according to the changes in the workpiece material, the rotation speed of the saw band 12, and the cutting depth. When the workpiece is hard or thick, the feed system slows down appropriately to ensure the cutting stability of the saw band 12. When the workpiece is thin or soft, the feed system can speed up appropriately to improve the cutting efficiency. By adjusting the feed speed and the power output of the motor 14, it is ensured that the saw band 12 works at the optimal cutting angle and pressure.
[0032] 7. Cutting process monitoring and real-time adjustment During the cutting process, the control system of the band saw machine body 1 monitors the tension of the saw band 12, the rotation speed of the saw wheel 11, the flow rate of the coolant and the feed rate in real time, and adjusts the parameters in time to prevent abnormalities. If the cutting resistance is too large or the saw band 12 deviates, the system will automatically sound an alarm and adjust the feed speed, tension or cooling intensity to ensure a continuous and stable cutting effect.
[0033] 8. Cutting completion and unloading When the workpiece is cut, the band saw machine body 1 stops running, the saw belt 12 stops running, and the cooling system is suspended. The workpiece clamping device 13 is released, and the operator removes the cut workpiece. At this time, the operator can check the quality of the cut surface to ensure that it meets the requirements.
[0034] 9. Maintenance and cleaning After the band saw machine body 1 has finished its work, the operator cleans and inspects the saw band 12, the saw wheel 11 and the cooling system. The saw band 12 surface will be attached with cutting chips and lubricating oil, which need to be cleaned in time to prevent them from affecting the accuracy of the next cutting. The saw wheel 11 and the guide device also need to be inspected and cleaned to prevent the cutting residue from affecting the smooth operation of the saw band 12.
[0035] Through reasonable maintenance and care, the service life of each component of the band saw can be extended, ensuring that it maintains accurate and efficient cutting performance for a long time.
[0036] When using: The dynamic friction mechanism 2 for allowing the cutting piece to actively generate friction with the saw belt 12 to accelerate the cutting process has the following steps: like Figure 3 to Figure 4 As shown, the operator starts the reducer fixedly connected to the output end of the drive shaft 29, and the rotation of the drive shaft 29 drives the short rod 28 rotatably connected to one end thereof to rotate, and the rotation of the short rod 28 drives the long rod 27 rotatably connected to one end thereof to rotate, so that the rotation of the long rod 27 also drives the rotating plate tooth 25 rotatably connected to one end thereof to deflect and rotate, and the deflection of the rotating plate tooth 25 also causes the upper gear 22 meshing with its outer wall to rotate, so that the rotation of the upper gear 22 drives the lower gear 2 fixedly connected to its lower end 6 rotates, so that the rotation of the gear 26 pushes the toothed plate strip 24 meshing with the outer wall thereof to move inside the wedge block 23, and then the tail end of the cutting piece placed inside the placing plate 212 moves synchronously with the movement of the toothed plate strip 24, so that when the saw belt 12 moves to cut the surface of the object, the tail end of the cutting piece placed inside the placing plate 212 actively rubs against the saw belt 12, and at the same time, the deflection and reset process of the rotating plate teeth 25 causes the placing plate 212 to reciprocate and rub against the surface of the saw belt 12 through a series of actions; The vibration hedging mechanism 3 steps for generating a hedging effect with the cutting vibration of the saw belt 12 to offset part of the irregular vibration: like Figure 5 to Figure 6 As shown, when the lower gear 26 rotates, the fixed shaft 31 fixedly connected to one end of the lower gear 26 and the universal ball 32 will rotate together, so that the push plate 33 eccentrically fixedly connected to the outer wall of the universal ball 32 will rotate eccentrically, and the eccentric rotation of the push plate 33 will push the long shaft 36 fixedly connected to the outer walls of both sides of the buckle shaft 34 to reciprocate left and right at the inner wall of the vertical block 35, so the left and right reciprocating movement of the long shaft 36 will drive the card plate 37 fixedly connected to one end thereof to move synchronously, and the vibration cylinder 38 rotatably connected to the outer wall of the card plate 37 will achieve slight deflection and shaking with the left and right reciprocating movement of the card plate 37, so that the slight deflection and rotation of the vibration cylinder 38 will push the placement plate 212 that its top end contacts to vibrate; Temperature-controlled balancing mechanism to provide additional support and reduce local overheating of the material 4 steps: like Figures 7 and 8 As shown, when the tooth plate strip 24 moves inside the wedge block 23, the circular plate 211 fixedly connected to the outer wall of one end of the tooth plate strip 24 and the external plate 41 fixedly connected to the outer wall of the circular plate 211 will move synchronously, so that the obstacle column 42 fixedly connected to the outer wall of one end of the external plate 41 will be disengaged from the initial position where it abuts against the outer walls of the upper and lower support columns 410 and 46, and then the upper and lower support columns 410 and 46 will be pushed by them to deflect inward in the same direction, so that the lower groove provided at one end of the lower clamping plate 49 and the upper clamping plate 45 provided at one end The upper slot of the outer plate 41 is deflected outwardly to open, thereby loosening the tail end of the cutting piece placed in the placement plate 212. Similarly, when the external plate 41 is reset, the external plate 41 will drive the obstacle column 42 to make its outer wall squeeze the upper support column 410 and the lower support column 46, so that the lower clamping plate 49 and the upper clamping plate 45 are deflected outwardly, thereby the lower slot provided at one end of the lower clamping plate 49 and the upper slot provided at one end of the upper clamping plate 45 are gathered and contracted inwardly in the same direction, thereby tightening the tail end of the cutting piece placed in the placement plate 212; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
