[0031] In order to make those skilled in the art better understand the present application, Figure 1The steel material easy-cutting performance testing equipment involved in this application is briefly described.

[0032] See also Figure 1 , shows a schematic diagram of the external structure of a steel material cutting performance testing device in one embodiment of the present application.

[0033] like Figure 1 As shown, the steel easy-to-cut performance testing equipment described in the present application may include a controller touch screen 101, an emergency stop control button 102, an up control button 103, a down control button 104, a support 105, a linear slide 106, a linear servo motor 107, a slider 108, a rotary servo motor 109, a fixture 110, a drill bit 111, steel 112, a pad 113, a fixture 114, a drilling force detection device 115 and an equipment base 116.

[0034] First, various operating parameters of the steel easy-to-cut performance testing equipment can be set and read on the controller touch screen 101, such as setting the rotation speed and feed speed of the drill bit 111, and reading the drilling force detected by the drilling force detection device 115; in addition, an up control button 103 and a down control button 104 are also provided to facilitate the control of the up and down of the drill bit 111.

[0035] Secondly, the rotary servo motor 109 is fixed on the slider 108, and the fixture 110 is used to fix the drill bit 111 and is connected to the rotary servo motor 109, so that the drill bit 111 can rotate under the control of the rotary servo motor 109; the slider 108 is arranged on the slide rail side of the linear slide 106, so that the slider 108 can move up and down along the slide rail of the linear slide 106 under the control of the linear servo motor 107; the linear slide 106 is fixed on the pillar 105.

[0037] Next, this application will elaborate on the proposed steel cutting performance testing method.

[0038] Reference Figure 2 , which shows a flow chart of a method for detecting the easy cutting performance of steel in an embodiment of the present application. The method for detecting the easy cutting performance of steel can be executed by a device having a computing and processing function, referring to Figure 2 As shown, the steel material cutting performance detection method includes at least steps 210 to 230, which are described in detail as follows:

[0039] Step 210, obtaining a first target drilling force of the steel sample.

[0040] Step 220, obtaining a second target drilling force of the steel to be tested.

[0041] Step 230: Determine the easy cutting index of the steel to be tested based on the first target drilling force and the second target drilling force, wherein the easy cutting index is used to characterize the easy cutting performance of the steel to be tested.

[0042] In the present application, the steel sample and the steel to be tested meet the set specifications, which can not only prevent the difference in shape and size between the steel sample and the steel to be tested from affecting the acquisition of drilling force, but also enable the steel sample and the steel to be tested to be stably fixed on the fixture to prevent movement during drilling by the drill bit and affect the acquisition of drilling force.

[0043] In the present application, the type of the steel sample can be predetermined and unchanged, that is, the first target drilling force is fixed, and the second target drilling force will change with the change of the type of the steel to be tested. Based on this, through the first target drilling force of the steel sample and the second target drilling force of the steel to be tested, it is determined that the easy-cutting index of the steel to be tested will change with the change of the type of the steel to be tested, so that the easy-cutting performance of the steel to be tested can be quantified, that is, the easy-cutting performance of different types of steel to be tested can be determined by directly comparing the easy-cutting index between different types of steel to be tested, thereby making the comparison of the easy-cutting performance between different steels to be tested objective and direct, and can improve the convenience of easy-cutting performance detection. In a specific embodiment of the present application, the steel sample can be specified as 45# steel. In some other embodiments, the steel sample can also be specified as other types of steel, and the present application does not make specific limitations on this.

[0044] In the above step 210, the first target drilling force of the steel sample is obtained, which can be specifically performed according to the following steps 211 to 213:

[0045] Step 211, controlling a drill bit of a drilling assembly to contact the surface of the steel sample, wherein the drill bit is used to drill the steel.

[0046] Step 212: Control the drill bit to drill the steel sample at a set rotation speed and a set feed speed.

[0047] Step 213: After the drill bit drills the steel sample for a first set time, control the drilling force detection device to obtain a first target drilling force of the drill bit on the steel sample.

[0048] In this application, please combine Figure 1The drilling assembly may include a rotary servo motor 109 , a fixture 110 and a drill bit 111 .

[0049] In the present application, the drill bit can be brought into contact with the surface of the steel sample by manual operation, or the drill bit can be brought into contact with the surface of the steel sample by automatic control through a steel cutting performance testing device. Based on this, a distance detection device can be provided on the drilling assembly to detect the distance between the drill bit and the steel sample, thereby providing a basis for determining whether the drill bit is in contact with the surface of the steel sample.

[0050] In the present application, it can be understood that controlling the contact between the drill bit and the surface of the steel sample first can ensure that the drill bit starts drilling the steel sample from the correct position to prevent the drilling position from deviating and causing the accuracy of the obtained drilling force to decrease, thereby improving the accuracy of the easy-to-cut index, so that the easy-to-cut index can more accurately reflect the easy-to-cut performance of the steel.

[0051] In the present application, several points (for example, 3-5 points) can be selected in the rolling direction and perpendicular to the rolling direction of the steel sample for drilling, so as to avoid the influence of the rolling process of the steel sample and the uniformity of the steel sample on the drilling force. In addition, by controlling the drill bit to drill the steel sample with a set rotation speed and a set feed speed, it can be ensured that the conditions of the drill bit remain consistent when drilling the steel sample multiple times, thereby avoiding the error caused by the different rotation speeds and feed speeds of the drill bit in multiple drillings when obtaining the drilling force, and improving the accuracy of drilling force acquisition.

[0052] In a specific embodiment of the present application, the first set time length may be 3 seconds. According to actual needs, the first set time length may also be other parameter values. The present application does not make too many restrictions on this.

[0053] In the present application, the drill bit is first controlled to drill the steel sample for a first set time, so that the drilling force generated by the drill bit when drilling the steel sample can be gradually stabilized, and then the drilling force detection device is controlled to obtain the first target drilling force of the drill bit on the steel sample, thereby reducing the error caused by instability when the drill bit drills the steel sample and improving the accuracy of drilling force acquisition.

[0054] In the above step 213, the drilling force detection device is controlled to obtain the first target drilling force of the drill bit on the steel sample, which can be specifically performed according to the following steps 2131 to 2133:

[0055] Step 2131, controlling the drilling force detection device to obtain a first measured drilling force of the drill bit on the steel sample once at a second set time interval.

[0056] Step 2132, while the drilling force detection device obtains the first measured drilling force, controls the drill bit to continue drilling the steel sample for a third set time period, and the third set time period is greater than the second set time period.

[0057] Step 2133: determine an average value of each of the first measured drilling forces obtained within a third set time period as the first target drilling force.

[0058] In a specific embodiment of the present application, the second set time length may be 0.2s, and the third set time length may be 20s. According to actual needs, the second set time length and the third set time length may also be other parameter values. In this regard, the present application does not impose too many restrictions.

[0059] In the present application, by obtaining the first measured drilling force of the drill bit on the steel sample once every second set time period within the third set time period, and taking the average value of each of the first measured drilling forces obtained within the third set time period as the first target drilling force, the random error caused by external conditions (such as equipment accuracy) in obtaining the drilling force can be reduced, thereby improving the accuracy of the obtained first target drilling force, and then improving the accuracy of the easy-to-cut index, so that the easy-to-cut index can more accurately reflect the easy-to-cut performance of the steel.

[0060] In the above step 220, the second target drilling force of the steel to be tested is obtained, which can be specifically performed according to the following steps 221 to 223:

[0061] Step 221, controlling the drill bit of the drilling assembly to contact the surface of the steel material to be tested.

[0062] Step 222: Control the drill bit to drill the steel material to be tested at the set rotation speed and the set feed speed.

[0063] Step 223: After the drill bit drills the steel material to be tested for a first set time period, the drilling force detection device is controlled to obtain a second target drilling force of the drill bit on the steel material to be tested.

[0064] In the present application, the drill bit can be brought into contact with the surface of the steel to be tested by manual operation, or the drill bit can be automatically controlled to contact with the surface of the steel to be tested by a steel cutting performance testing device. Based on this, a distance detection device can be set on the drilling assembly to detect the distance between the drill bit and the steel to be tested, so as to provide a basis for determining whether the drill bit is in contact with the surface of the steel to be tested. The present application does not impose too many restrictions on this.

[0065] In the present application, it can be understood that controlling the drill bit to contact the surface of the steel to be tested first can ensure that the drill bit starts drilling the steel to be tested from the correct position to prevent the drilling position from deviating and causing the accuracy of the obtained drilling force to decrease, thereby improving the accuracy of the easy-to-cut index, so that the easy-to-cut index can more accurately reflect the easy-to-cut performance of the steel.

[0066] In the present application, several points (for example, 3-5 points) can be selected in the rolling direction and perpendicular to the rolling direction of the steel to be tested for drilling, so as to avoid the influence of the rolling process of the steel to be tested and the uniformity of the steel to be tested on the drilling force. In addition, by controlling the drill bit to drill the steel to be tested at a set rotation speed and a set feed speed, it can not only ensure that the conditions of the drill bit are consistent when drilling the steel to be tested multiple times, but also avoid the error caused by the different rotation speeds and feed speeds of the drill bit in multiple drillings when obtaining the drilling force, thereby improving the accuracy of the drilling force acquisition, and can also make the rotation speed and feed speed of the drill bit when drilling the steel to be tested and the steel sample remain the same, thereby ensuring that the process of obtaining the drilling force will not be affected by other factors.

[0067] In a specific embodiment of the present application, the first set time length may be 3 seconds. According to actual needs, the first set time length may also be other parameter values. The present application does not make too many restrictions on this.

[0068] In the present application, the drill bit is first controlled to drill the steel to be tested for a first set time, so that the drilling force generated by the drill bit when drilling the steel to be tested can be gradually stabilized, and then the drilling force detection device is controlled to obtain the first target drilling force of the drill bit on the steel to be tested, thereby reducing the error caused by instability when the drill bit is drilling the steel to be tested and improving the accuracy of drilling force acquisition.

[0069] In the above step 223, the controlling of the drilling force detection device to obtain the second target drilling force of the drill bit on the steel to be tested can be specifically performed according to the following steps 2231 to 2233:

[0070] Step 2231, controlling the drilling force detection device to obtain a second measured drilling force of the drill bit on the steel to be tested once at a second set time interval.

[0071] Step 2232: while the drilling force detection device obtains the second measured drilling force, control the drill bit to continue drilling the steel material to be tested for a third set time period.

[0072] Step 2233: determine an average value of each of the second measured drilling forces obtained within a third set time period as the second target drilling force.

[0073] In a specific embodiment of the present application, the second set time length may be 0.2s, and the third set time length may be 20s. According to actual needs, the second set time length and the third set time length may also be other parameter values. In this regard, the present application does not impose too many restrictions.

[0074] In the present application, by obtaining the first measured drilling force of the drill bit on the steel to be tested once every second set time period within the third set time period, and taking the average value of each of the second measured drilling forces obtained within the third set time period as the second target drilling force, the random error caused by external conditions (such as equipment accuracy) in obtaining the drilling force can be reduced, thereby improving the accuracy of the obtained second target drilling force, and further improving the accuracy of the easy-to-cut index obtained based on the first target drilling force and the second target drilling force, so that the easy-to-cut index can more accurately reflect the easy-to-cut performance of the steel to be tested.

[0075] In the above step 230, the machinability index of the steel to be tested can be determined by the following formula (1):

[0076] τ=[1-F2 / (2×F1)]×100 (1)

[0077] Wherein, τ represents the easy cutting index, F1 represents the first target drilling force, and F2 represents the second target drilling force.

[0078] In some specific embodiments of the present application, as shown in Table 1 and Table 2, see Table 1, which shows the drilling force measurement results of different steels to be tested in an embodiment of the present application, and see Table 2, which shows the easy cutting index calculation results of different steels to be tested in an embodiment of the present application. Taking steel 1 to be tested as an example, the first target drilling force F1 is 483.2N, and the second target drilling force F2 is 243.1N. Then the easy cutting index τ of the steel 1 to be tested is [1-F2 / (2×F1)]×100=74.8; taking steel 4 to be tested as an example, the first target drilling force F1 is 483.2N, and the second target drilling force F2 is 633.9N. Then the easy cutting index c of the steel 4 to be tested is [1-F2 / (2×F1)]×100=34.4.

[0083] Table 2

[0084] In the present application, the machinability index of the steel to be tested is determined based on the above formula (1). When the steel to be tested is easier to cut than the steel sample (such as the steel to be tested 1), the drilling force generated when the drill bit drills it is smaller, and the calculated machinability index is larger. The higher the machinability performance, the larger the machinability index. When the steel to be tested is more difficult to cut than the steel sample (such as the steel to be tested 4), the drilling force generated when the drill bit drills it is larger, and the machinability index is smaller. The worse the machinability performance, the smaller the machinability index. This can more intuitively display the relationship between the machinability of the steel and the machinability index, thereby improving the convenience of steel machinability testing.

[0085] Based on the technical solution proposed in the present application, by controlling the drilling assembly to drill the steel sample and the steel to be tested, and waiting for the first set time before obtaining the drilling force of the drill bit on the steel sample and the steel to be tested, it can be ensured that the drilling force generated by the drill bit when drilling the steel sample and the steel to be tested reaches a stable state. At the same time, the drilling force detection device is controlled to obtain the drilling force generated by the drill bit when drilling the steel sample and the steel to be tested once every second time interval within the third set time, which can reduce the impact of random errors on the results. Finally, the first target drilling force of the steel sample and the second target drilling force of the steel to be tested are converted into the easy-to-cut index of the steel to be tested using a mathematical formula, and the easy-to-cut performance of the steel to be tested is quantified, which is convenient for comparing and evaluating the easy-to-cut performance of different steels to be tested, and improves the convenience of steel easy-to-cut performance detection.
