[0040] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0041] like Figure 1-Figure 12 As shown, the present invention provides a surface treatment device for alloy rolls after quenching, comprising a controller, a moving track extending linearly in one direction, a clamping machine base arranged on the moving track and used to fix the alloy rolls after quenching, and a sandblasting device and a grinding wheel device sequentially arranged at intervals along the extending direction of the moving track;

[0042] The clamping machine base comprises two clamping tables which are arranged opposite to each other and can be movably arranged on a movable track, and the two clamping tables have rotatable clamping parts on the opposite surfaces thereof, and the two clamping parts clamp an alloy roller together so as to drive the alloy roller to rotate axially during processing;

[0043] The sandblasting equipment comprises two sandblasting assemblies symmetrically distributed on both sides of the clamping machine base, and the sandblasting assemblies are arranged on a first moving platform which can move on a horizontal plane along the extension direction of the moving track and perpendicular to the extension direction of the moving track, and the sandblasting assembly comprises a semicircular ring-shaped sandblasting head, and the two sandblasting heads of the two sandblasting assemblies can enclose a ring body with a radius larger than that of the alloy rolling roller and a plurality of nozzles evenly distributed in a ring shape on the inner side wall of the corresponding ring body;

[0044] The grinding wheel device comprises two grinding wheel assemblies symmetrically distributed on both sides of the clamping machine base, and the grinding wheel assembly is arranged on a second movable platform which can move along the extending direction of the movable track and perpendicular to the extending direction of the movable track on a horizontal plane, and the grinding wheel assembly comprises a grinding wheel disc and a servo motor for driving the grinding wheel disc;

[0045] When the alloy roller after quenching is fixed between the two clamping parts, the controller first controls the first movable platform to move so that the two sandblasting heads enclose a circular ring body corresponding to the position to be sandblasted of the alloy roller, and then drives the sandblasting head to perform sandblasting on the position to be sandblasted of the alloy roller and controls the first movable platform to move along the axial direction of the alloy roller at the same time, and the moving range covers all the positions to be sandblasted of the alloy roller;

[0046] After sandblasting, the controller first controls the clamping base to move along the moving track to the position of the corresponding grinding wheel equipment, and then controls the clamping part of the clamping base to drive the alloy roller to rotate along the preset direction, and at the same time controls the two grinding wheel discs to rotate at a first preset speed and in the same direction as the preset direction; controls the second moving platform to move so that the two grinding wheel discs simultaneously perform initial grinding on the position of the alloy roller after sandblasting, and at the same time controls the second moving platform to reciprocate along the axial direction of the alloy roller, and the moving range covers all the positions of the alloy roller after sandblasting; after the initial grinding, controls the two grinding wheel discs to rotate at a second preset speed and in the same direction as the preset direction for fine grinding, and at the same time controls the second moving platform to reciprocate along the axial direction of the alloy roller, and the moving range covers all the initially ground positions of the alloy roller; the second preset speed is greater than the first preset speed.

[0047] From the above description, it can be seen that the present invention has the following beneficial effects:

[0048] The present invention provides a surface treatment device for alloy rollers after quenching by blasting. The device comprises a clamping machine base for fixing the alloy rollers after quenching by blasting on a moving track, and a sandblasting device and a grinding wheel device are sequentially arranged at intervals along the extension direction of the moving track. The device is electrically connected to the sandblasting device and the grinding wheel device through a controller to control the sandblasting device and the grinding wheel device to perform sandblasting and grinding operations on the alloy rollers after quenching fixed on the clamping machine base, respectively. Specifically, the order of sandblasting first and then grinding is adopted, and the order of initial grinding first and then fine grinding is adopted during the grinding process, that is, the same grinding wheel disc but different rotation speeds are used to successively grind the alloy rollers after sandblasting. The sandblasting device and the grinding wheel device cooperate with each other to ensure that the oxides formed on the surface of the alloy rollers after quenching are effectively removed, and the efficiency of removing the oxides by chemical immersion is higher and the cost is lower. Furthermore, the two sandblasting heads of the two sandblasting assemblies can be combined to form a ring body with a radius larger than that of the alloy roller and corresponding to the position to be sandblasted of the alloy roller. The multiple nozzles evenly distributed in a ring shape on the inner wall of the corresponding ring body can form an annular sandblasting surface, and the position to be sandblasted of the alloy roller is evenly sandblasted. At the same time, the first movable platform is controlled to move along the axial direction of the alloy roller, which not only obtains the effect of uniform sandblasting, but also greatly improves the sandblasting efficiency. The two clamping parts of the clamping machine base can drive the alloy roller to rotate axially during processing, and the two grinding wheels have the same rotation direction as the alloy roller, thereby increasing the grinding efficiency. The grinding wheel is driven by a servo motor to improve the output stability and output accuracy.

[0049] Furthermore, when the two sandblasting heads are combined to form a circular body and correspond to the position of the alloy roller to be sandblasted, the nozzle on the sandblasting head is facing the position of the alloy roller to be sandblasted and the distance between the nozzle on the sandblasting head and the position of the alloy roller to be sandblasted is in the range of 30mm-70mm, and the air pressure range of the sandblasting equipment is 0.3Mpa-0.7Mpa.

[0050] From the above description, it can be seen that the distance between the sandblasting head and the alloy roller is one of the main factors affecting the outlet pressure of the sandblasting head. When the distance is too close, the jet speed is reduced due to the inertia of the abrasive particles and the recoil force of the compressed air, thereby generating a large impact kinetic energy, causing pits or grooves on the surface of the alloy roller; if the distance is too far, the energy consumption of the jet is too large, so the above parameter range can meet the sandblasting effect.

[0051] Furthermore, the distance between the nozzle on the sandblasting head and the position of the alloy roller to be sandblasted is 50 mm, and the air pressure of the sandblasting equipment is 0.56 MPa.

[0052] From the above description, it can be seen that after a large number of tests, it is concluded that the use of the above specific parameter values ​​can achieve a dynamic balance between distance and air pressure, achieve a better sandblasting effect, and provide further auxiliary effect for subsequent grinding treatment.

[0053] Furthermore, the sandblasting assembly also includes a first infrared sensor electrically connected to the controller, the orientation of the first infrared sensor is perpendicular to the axial direction of the alloy roller, and the controller is configured to control the moving range of the first movable platform to cover all positions to be sandblasted of the alloy roller based on data feedback from the first infrared sensor.

[0054] From the above description, it can be seen that by setting the first infrared sensor, infrared feedback data is used to determine all the positions of the alloy roller to be sandblasted, that is, there are steps between all the positions of the alloy roller to be sandblasted and the positions that do not need to be processed. The step is used as a dividing line. The infrared feedback data corresponding to the positions on both sides of the step are different and the difference is large. It can be judged that the first movable platform has moved to the boundary of the alloy roller to be sandblasted, and then the first movable platform is controlled to move in the reverse direction. Similarly, at the boundary on the other side, the first movable platform is controlled to move in the reverse direction again, thereby forming a reciprocating movement.

[0055] Furthermore, the rotation speed of the alloy roller is 1100 rpm, the second preset rotation speed is 2800 rpm, the first preset rotation speed is 2000 rpm, the initial grinding time is 3 minutes, and the fine grinding time is 2 minutes.

[0056] From the above description, it can be seen that by adopting the above parameters, a relatively low-speed and relatively long initial grinding can be achieved, and then a relatively high-speed and relatively short fine grinding can be adopted. Of course, the rotation speeds of both are higher than the rotation speed of the alloy rolling roller, which can effectively achieve a better grinding effect, and the oxide removal rate can be close to 100%.

[0057] Furthermore, the grinding wheel assembly also includes a second infrared sensor electrically connected to the controller, the second infrared sensor is oriented perpendicular to the axial direction of the alloy roller, and the controller is configured to control the moving range of the second movable platform to cover all positions of the alloy roller after sandblasting based on data fed back by the second infrared sensor.

[0058] From the above description, it can be seen that by setting up a second infrared sensor, infrared feedback data is used to determine the positions of all the alloy rollers after sandblasting, that is, there is a step between the positions of all the alloy rollers after sandblasting and the positions that do not need to be processed. The step is used as a dividing line. The infrared feedback data corresponding to the positions on both sides of the step are different and the difference is large. It can be determined that the first movable platform has moved to the boundary of all the positions of the alloy rollers after sandblasting, and then the first movable platform is controlled to move in the reverse direction. Similarly, at the boundary on the other side, the first movable platform is controlled to move in the reverse direction again, thereby forming a reciprocating movement.

[0059] Furthermore, the clamping portion is embedded with a pressure sensor, and the pressure sensor is electrically connected to the controller.

[0060] From the above description, it can be seen that the pressure sensor is used to detect the clamping force of the clamping part on the alloy roller. When the clamping force reaches the preset pressure value, it means that the alloy roller has been fixed in place, and then it is fed back to the controller, and then the controller starts to trigger the sandblasting process, thereby improving the degree of intelligence.

[0061] Furthermore, it also includes a display electrically connected to the controller.

[0062] From the above description, it can be seen that the display can display the current processing progress, specific parameters of each device and other related data, so that the operator can know the specific processing status in time.

[0063] Furthermore, it also includes a communication module electrically connected to the controller, and the communication module is used to establish a communication connection with a monitoring platform of an external device.

[0064] From the above description, it can be seen that by setting up a communication module, data interaction can be achieved with the monitoring platform of the peripheral device, which is convenient for remote monitoring.

[0065] Furthermore, it also includes an alarm module electrically connected to the controller, and the alarm module is used to issue an alarm by ringing a bell or flashing a light when an abnormal event occurs.

[0066] From the above description, it can be seen that by setting up an alarm module, an alarm can be issued by ringing a bell or flashing a light when an abnormal event occurs, so that the operator can be aware of the abnormal situation in time.

[0067] Several preferred embodiments or application examples are listed below to help those skilled in the art better understand the technical content of the present invention and the technical contribution made by the present invention relative to the prior art:

[0068] Preferred embodiment one:

[0069] like Figures 1 to 12 As shown, the present invention provides a surface treatment device for alloy rollers after quenching, comprising a controller, a movable track 1 extending linearly in one direction, a clamping base 2 arranged on the movable track 1 and used to fix the alloy rollers after quenching, and a sandblasting device 3 and a grinding wheel device 4 arranged in sequence along the extending direction of the movable track 1; wherein, the alloy roller 5 after quenching is columnar, and the position in the middle is the position to be processed, and the corresponding diameter is larger than the diameter of other positions, that is, it is stepped and dislocated with the positions that do not need to be processed.

[0070] The clamping machine base 2 includes two clamping tables 21 which are arranged opposite to each other and can be movably arranged on the movable track 1. The two clamping tables 21 have rotatable clamping parts 22 on the opposite surfaces. The two clamping parts 22 jointly clamp an alloy rolling roller 5 so as to drive the alloy rolling roller 5 to rotate axially during processing. The movement of the clamping table 21 can be controlled by the existing cylinder.

[0071] The sandblasting equipment 3 comprises two sandblasting assemblies 31 symmetrically distributed on both sides of the clamping base 2, and the sandblasting assemblies 31 are arranged on a first moving platform 32 which can move on a horizontal plane along the extension direction of the moving track 1 and perpendicular to the extension direction of the moving track 1, and the sandblasting assembly 31 comprises a semicircular ring-shaped sandblasting head 311, and the two sandblasting heads 311 of the two sandblasting assemblies can enclose a ring body with a radius larger than that of the alloy rolling roller and a plurality of nozzles evenly distributed in a ring shape on the inner side wall of the corresponding ring body;

[0072] In this embodiment, when two sandblasting heads 311 are combined into a ring body and correspond to the position to be sandblasted of the alloy roller, the nozzle 312 on the sandblasting head 311 faces the position to be sandblasted of the alloy roller, the distance between the nozzle on the sandblasting head and the position to be sandblasted of the alloy roller is 50mm, and the air pressure of the sandblasting equipment is 0.56Mpa. The distance between the sandblasting head and the alloy roller is one of the main factors affecting the outlet pressure of the sandblasting head. When the distance is too close, the jet velocity is reduced due to the inertia of the abrasive particles and the recoil force of the compressed air, thereby generating a large impact kinetic energy, causing pits or grooves to appear on the surface of the alloy roller; and if the distance is too far, the energy consumption of the jet is too large, so the above parameter range can be used to meet the sandblasting effect. By using the above specific parameter values, a dynamic balance can be achieved between the distance and the air pressure, and a better sandblasting effect can be achieved, providing further auxiliary effects for subsequent grinding treatment.

[0073] The grinding wheel device 4 comprises two grinding wheel assemblies 41 symmetrically distributed on both sides of the clamping machine base 2, and the grinding wheel assembly 41 is arranged on a second moving platform 42 which can move on a horizontal plane along the extension direction of the moving track 1 and perpendicular to the extension direction of the moving track 1, and the grinding wheel assembly 41 comprises a grinding wheel disc 411 and a servo motor 412 for driving the grinding wheel disc 411; in this embodiment, the grinding wheel disc 411 adopts a resin diamond grinding wheel manufactured by Henan Kemei Abrasives Co., Ltd. The servo motor 412 adopts an MS series servo motor produced by Jingyan Group.

[0074] like Figures 1 to 4 As shown, when the alloy roller 5 after quenching is fixed between the two clamping parts 22, the controller first controls the first movable platform 32 to move so that the two sandblasting heads 311 are surrounded by a circular ring body and correspond to the position to be sandblasted of the alloy roller, and then drives the sandblasting head 311 to perform sandblasting on the position to be sandblasted of the alloy roller and controls the first movable platform 32 to move along the axial direction of the alloy roller at the same time, and the moving range covers all the positions to be sandblasted of the alloy roller;

[0075] like Figures 5 to 8 As shown, after the sandblasting treatment, the controller first controls the clamping base 2 to move along the moving track 1 to the position corresponding to the grinding wheel equipment, and then controls the clamping portion 22 of the clamping base to drive the alloy roller 5 to rotate along the preset direction, wherein the rotation speed of the alloy roller is 1100 rpm; at the same time, the two grinding wheel discs 411 are controlled to rotate at a first preset speed and in the same direction as the preset direction, wherein the first preset speed is 2000 rpm;

[0076] like Figures 9 to 12 As shown, the second movable platform 42 is controlled to move so that the two grinding wheels 411 simultaneously perform initial grinding on the positions of the alloy roller after sandblasting, and the initial grinding time is 3 minutes. At the same time, the second movable platform 42 is controlled to reciprocate along the axial direction of the alloy roller 5, and the moving range covers all the positions of the alloy roller after sandblasting;

[0077] After the initial grinding, the two grinding wheels 411 are controlled to rotate at a second preset speed and in the same direction as the preset direction for fine grinding, wherein the second preset speed is 2800 rpm and the fine grinding time is 2 minutes; at the same time, the second movable platform 42 is controlled to move back and forth along the axial direction of the alloy roller, and the moving range covers all the initially ground positions of the alloy roller.

[0078] By adopting the above parameters, a relatively low-speed and relatively long initial grinding is achieved, and then a relatively high-speed and relatively short fine grinding is adopted. Of course, the rotation speeds of both are higher than the rotation speed of the alloy roller, which can effectively achieve a better grinding effect, and the oxide removal rate can be close to 100%.

[0079] In this embodiment, the first moving platform 32 and the second moving platform 42 can adopt the same existing structure, that is, they can move on a horizontal plane along the extending direction of the moving track and perpendicular to the extending direction of the moving track.

[0080] The sandblasting assembly also includes a first infrared sensor (not shown in the figure) electrically connected to the controller, the first infrared sensor is oriented perpendicular to the axial direction of the alloy roller, and the controller is configured to control the movement range of the first movable platform to cover all positions of the alloy roller to be sandblasted according to the data fed back by the first infrared sensor. The grinding wheel assembly also includes a second infrared sensor (not shown in the figure) electrically connected to the controller, the second infrared sensor is oriented perpendicular to the axial direction of the alloy roller, and the controller is configured to control the movement range of the second movable platform to cover all positions of the alloy roller after sandblasting according to the data fed back by the second infrared sensor. In this embodiment, both the first infrared sensor and the second infrared sensor can be existing products, and only need to be electrically connected to the controller, and the collected infrared data can be fed back to the controller. The controller can realize the processing boundary through simple logical judgment.

[0081] By setting a first infrared sensor, infrared feedback data is used to judge all positions of the alloy roller to be sandblasted, that is, there is a step between all positions of the alloy roller to be sandblasted and the position that does not need to be processed, and the step is used as a dividing line. The infrared feedback data corresponding to the positions on both sides of the step are different and the difference is large. It can be judged that the first mobile station moves to the boundary of the alloy roller to be sandblasted, and then the first mobile station is controlled to move in the opposite direction. Similarly, at the boundary on the other side, the first mobile station is controlled to move in the opposite direction again, thereby forming a reciprocating movement. By setting a second infrared sensor, infrared feedback data is used to judge all positions of the alloy roller after sandblasting, that is, there is a step between all positions of the alloy roller after sandblasting and the position that does not need to be processed, and the step is used as a dividing line. The infrared feedback data corresponding to the positions on both sides of the step are different and the difference is large. It can be judged that the first mobile station moves to the boundary of all positions of the alloy roller after sandblasting, and then the first mobile station is controlled to move in the opposite direction. Similarly, at the boundary on the other side, the first mobile station is controlled to move in the opposite direction again, thereby forming a reciprocating movement.

[0082] The clamping part is embedded with a pressure sensor (not shown in the figure), which is electrically connected to the controller. The pressure sensor is used to detect the clamping force of the clamping part on the alloy roller. When the clamping force reaches a preset pressure value, it means that the alloy roller has been fixed in place, and then the controller is fed back to trigger the sandblasting process, thereby improving the degree of intelligence.

[0083] The above-mentioned surface treatment device for alloy rollers after quenching also includes a display, a communication module and an alarm module electrically connected to the controller respectively; the display can display the current processing progress, the specific parameters of each device and other related data, so that the operator can know the specific processing situation in time. The communication module is used to establish a communication connection with the monitoring platform of the peripheral device, and can realize data interaction with the monitoring platform of the peripheral device, which is convenient for remote monitoring. The alarm module is used to give an alarm by ringing a bell or flashing a light when an abnormal event occurs. It can give an alarm by ringing a bell or flashing a light when an abnormal event occurs, so that the operator can know the abnormal situation in time.

[0084] It should be noted that the electronic devices used above, such as pressure sensors, infrared sensors, controllers, communication modules, displays, and alarm modules, can all be existing products, and the specific connection methods can also be existing electrical connection methods.

[0085] The present invention has been described by the above-mentioned relevant embodiments and drawings, but the above-mentioned embodiments are only examples for implementing the present invention.
