Description

Technical Field

[0001] This invention relates to the field of metal sawing technology, specifically to a band saw with a positioning and clamping mechanism for stopper rod sprue treatment. Background Technology

[0002] Stopper rod nozzles are refractory components used in continuous steel casting. The interior of the integral stopper rod is generally equipped with a metal steel core. In order to process round steel raw materials, a band saw is used to cut the round steel raw materials. However, the band saw under the current technology still has the following shortcomings when cutting round steel raw materials.

[0003] Firstly, the saw blades used in existing band saws are made of high-toughness alloy spring steel to achieve the flexible characteristics of the saw blade. Therefore, band saws use a limiting guide mechanism to keep the saw blade vertically downward when cutting round steel raw materials, without deviation or tilting. However, the high-speed rotating saw blade will come into contact with the limiting guide mechanism, which will continuously generate heat and make the saw blade high temperature, thereby reducing its base toughness and lateral stiffness. The saw blade is more likely to elastically deviate under the action of cutting lateral force, forming a bevel cut, reducing the accuracy of steel core cutting, and the high temperature will weaken the hardness of the saw teeth, resulting in a decrease in cutting ability. Existing band saws do not have the function of cooling the saw blade at the limiting guide mechanism.

[0004] Secondly, when band saws cut round steel raw materials, sawdust often falls onto the machine base, and the operator needs to clean the sawdust that falls onto the machine base frequently. However, band saws under the current technology do not have a convenient and automatic sawdust cleaning function.

[0005] Therefore, in order to solve the above problems, there is a need to provide a band saw with a positioning and clamping mechanism for stopper rod sprue treatment. Summary of the Invention

[0006] The purpose of this invention is to provide a band saw with a positioning and clamping mechanism for stopper rod sprue treatment, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a band saw with a positioning and clamping mechanism for stopper rod sprue treatment, comprising a machine base assembly, a sawing assembly mounted on the machine base assembly, a guide cooling mechanism mounted on the sawing assembly, and a guide wheel drive mechanism mounted on the guide cooling mechanism;

[0008] The guiding cooling mechanism has a left front flow channel, a left front curved channel, a left rear curved channel, a left rear flow channel, a right rear flow channel, a right rear curved channel, a right front curved channel, and a right front flow channel. The above flow channels are connected in sequence to form a unidirectional circulation flow channel. A left front gear ring impeller, a left rear gear ring impeller, a right front gear ring impeller, and a right rear gear ring impeller are movably installed in the left front flow channel, the left rear flow channel, the right front flow channel, and the right rear flow channel, respectively. The above impellers are driven by the guide wheel drive mechanism.

[0009] When the left front gear ring impeller and the right rear gear ring impeller are driven to rotate, the rotation direction of their impellers causes the coolant to move downwards, and when the left rear gear ring impeller and the right front gear ring impeller are driven to rotate, the rotation direction of their impellers causes the coolant to move upwards, and the coolant flows in the unidirectional circulation channel.

A left square column is fixedly installed at the left end of the horizontal plate, and a right square column is fixedly installed at the right end of the horizontal plate. Guide grooves are provided at the bottom of both the left and right square columns, and the flexible saw blade passes through the guide grooves and is guided and limited by them.

[0015] Furthermore, the left column has a left front flow channel inside, in which a left front gear ring impeller is movably installed. The bottom of the left column has a left front curved channel, which is connected to the left front curved channel. Both the left front flow channel and the left front curved channel are located in front of the guide groove. The right column has a right front flow channel inside, in which a right front gear ring impeller is movably installed. The bottom of the right column has a right front curved channel, which is connected to the right front curved channel. Both the right front flow channel and the right front curved channel are located in front of the guide groove. The upper openings of the left and right front flow channels are connected to front water boxes, and the front water boxes are connected by evenly distributed front thin tubes.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. When the flexible saw blade enters the guide groove for further guidance and limiting, the coolant flowing in the left front curved track, left rear curved track, right front curved track, and right rear curved track will exchange heat and cool the flexible saw blade passing through this area, thereby preventing it from overheating due to friction. When the saw blade is running and cutting, the coolant circulation is automatically generated. When the saw is idle and the guide wheel does not rotate, the cooling circulation automatically stops. There is no ineffective energy consumption of the water pump. Moreover, the heat generated during cutting is concentrated in the limiting and guiding friction area, and the heat is directly exchanged internally at the heat source location, which is far superior to long-distance external spraying.

[0021] 2. The cutting position of the round steel raw material is located on the front side of the platform. Some of the sawdust produced by cutting falls into the chip collection trough for collection, and some falls onto the chip conveyor belt. The chip conveyor motor drives the drum to rotate, which drives the chip conveyor belt to move towards the chip collection trough, thereby continuously feeding the sawdust that falls onto the chip conveyor belt into the chip collection trough for collection. In this way, the sawdust produced during the cutting process can be automatically fed into the small space of the chip collection trough, which facilitates the centralized collection and subsequent cleaning of sawdust.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] Please see Figures 1 to 13 This invention provides a technical solution: a band saw with a positioning and clamping mechanism for stopper rod sprue treatment. This band saw with a positioning and clamping mechanism addresses the problem of continuous frictional heat generation between the high-speed movement of the saw band and the limiting and guiding mechanism, providing a new approach. The specific implementation is as follows:

[0038] Reference Figure 1 The machine includes a machine base assembly 1, a clamping assembly 2 on the machine base assembly 1, a sawing assembly 3 on the machine base assembly 1, a guide cooling mechanism 4 on the sawing assembly 3, and a guide wheel drive mechanism 5 on the guide cooling mechanism 4.

[0039] In this embodiment, the round steel raw material to be processed is clamped and fixed by the clamping assembly 2, the sawing assembly 3 cuts and processes the fixed round steel raw material, and the guide cooling mechanism 4 and the guide wheel drive mechanism 5 provide vertical guidance and limit the operation of the belt body. The guide cooling mechanism 4 and the guide wheel drive mechanism 5 can cool down the belt body operating here to prevent the belt body from generating high temperature due to continuous contact and friction with the guide cooling mechanism 4 and the guide wheel drive mechanism 5.

[0040] Reference Figures 2-4 The machine assembly 1 includes a base 101. A chip collection groove 102 is provided at one end of the front side of the base 101. An inner plate 103 and an outer plate 104 are fixedly installed at the other end of the front side of the base 101. The inner plate 103 and the outer plate 104 are respectively aligned with the two side walls of the chip collection groove 102.

The chip feeding belt 107 rotates in the direction of the chip collection groove 102.

[0041] In this embodiment, the cutting position of the round steel raw material is located in front of the platform 101. Part of the sawdust generated by cutting falls into the chip collection groove 102 for collection, and part falls onto the chip conveyor belt 107. The chip conveyor motor 109 drives the rotating drum 106 to rotate, causing the chip conveyor belt 107 to move towards the chip collection groove 102, thereby continuously feeding the sawdust that falls onto the chip conveyor belt 107 into the chip collection groove 102 for collection. In this way, the sawdust generated during the cutting process can be automatically fed into the small space of the chip collection groove 102, thereby facilitating the centralized collection and subsequent cleaning of the sawdust.

A handwheel 205 is fixedly installed at the end of the shaft of the lead screw 202. A support platform 206 is installed on the front side of the clamping platform 201.

[0043] In this embodiment, the rotating screw 202 drives the clamping plate 204 and the fixed plate 203 to cooperate in fixing and clamping the round steel material, thereby facilitating the cutting of the round steel material. The support platform 206 is used to receive part of the cut round steel material.

[0045] In this embodiment, the sawing motor 308 drives the drive wheel 309 to rotate via the transmission belt 310, thereby driving the driven wheel 306 to rotate, which in turn drives the worm gear 305 to rotate. The worm gear 305 drives the turbine 304 to rotate the right wheel 313, thereby driving the flexible saw band 316 to rotate. The front plate 303 can be raised and lowered using the movable shaft 302, so that the rotating flexible saw band 316 can cut the round steel raw material. The flexible saw band 316 uses a flexible metal material, generally high-toughness alloy spring steel. Since the material of the flexible saw band 316 is a technical means commonly used by those skilled in the art, it will not be described in this embodiment.

[0046] Reference Figures 8-12 The guiding cooling mechanism 4 includes a horizontal plate 401, which is fixedly installed on the front side of the beam plate 311.

[0049] Both sides of the left front gear ring impeller 406 are provided with circular rails 421, and the left square column 402 is provided with a matching swirl groove 422. The left front gear ring impeller 406 is movably installed in the left front flow channel 405 by means of the circular rails 421 and the swirl groove 422. The outer side of the left square column 402 is provided with a swirl groove 423, and some teeth of the left front gear ring impeller 406 are exposed in the swirl groove 423. The installation method of the left rear gear ring impeller 414, the right front gear ring impeller 409 and the right rear gear ring impeller 417 is the same as that of the left front gear ring impeller 406, so it will not be described in detail in this embodiment.

[0050] Evenly distributed fans 424 are also installed on the horizontal plate 401;

[0051] Reference Figure 13The guide wheel drive mechanism 5 includes a sealing chamber 501. The sealing chamber 501 is fixedly installed on the outer side of the left column 402 and the right column 403. The sealing chamber 501 is fixedly installed at the slot 423. The sealing chamber 501 is movably sleeved with the front shaft 502 and the rear shaft 503. The bottom ends of the front shaft 502 and the rear shaft 503 are respectively fixedly sleeved with the front guide wheel 504 and the rear guide wheel 505. The flexible saw blade 316 passes through the gap between the front guide wheel 504 and the rear guide wheel 505 and is limited and guided by them. Gears are fixedly sleeved on the shafts of the front shaft 502 and the rear shaft 503. The gears on the front shaft 502 and the rear shaft 503 are located in the sealing chamber 501 and are respectively connected to the left front gear ring impeller 406 and the left rear gear ring impeller 414. The driving method of the right front gear ring impeller 409 and the right rear gear ring impeller 417 is the same.

[0052] When the left front gear ring impeller 406 and the right rear gear ring impeller 417 are driven to rotate, the rotation direction of their impellers drives the coolant to move downward. When the left rear gear ring impeller 414 and the right front gear ring impeller 409 are driven to rotate, the rotation direction of their impellers drives the coolant to move upward. The coolant circulates unidirectionally in the left front flow channel 405, left front curved channel 407, left rear curved channel 415, left rear flow channel 413, rear thin tube 420, right rear flow channel 416, right rear curved channel 418, right front curved channel 410, right front flow channel 408, and front thin tube 412.

[0053] In this embodiment, the flexible saw blade 316 is limited and guided through the gap between the front guide wheel 504 and the rear guide wheel 505. The high-speed rotating flexible saw blade 316 drives the front guide wheel 504 and the rear guide wheel 505 to rotate, thereby driving the left front gear ring impeller 406 and the left rear gear ring impeller 414 to rotate through gears. The driving method of the right front gear ring impeller 409 and the right rear gear ring impeller 417 on the other side is the same. By setting the impeller rotation direction of the left front gear ring impeller 406, the right rear gear ring impeller 417, the left rear gear ring impeller 414, and the right front gear ring impeller 409, the coolant can be made to flow unidirectionally in the left front flow channel 405, the left front curved channel 407, the left rear curved channel 415, the left rear flow channel 413, the rear thin tube 420, the right rear flow channel 416, the right rear curved channel 418, the right front curved channel 410, the right front flow channel 408, and the front thin tube 412. In the circulating flow, when the flexible saw blade 316 enters the guide groove 404 for further guidance and limiting, the coolant flowing in the left front curved channel 407, left rear curved channel 415, right front curved channel 410, and right rear curved channel 418 will exchange heat and cool the flexible saw blade 316 passing through this point, thereby preventing it from overheating due to friction. When the coolant passes through the front thin tube 412 and the rear thin tube 420, it can quickly exchange heat and cool with the surrounding air, thereby reducing the coolant temperature again. The fan 424 can accelerate the airflow speed at this point. Furthermore, the device synchronously drives the coolant through the left front gear ring impeller 406, left rear gear ring impeller 414, right front gear ring impeller 409, and right rear gear ring impeller 417 respectively set in each flow channel, so that the coolant can flow stably in the flow channel circuit, improving its heat dissipation performance.
