Description

Technical Field

[0001] This invention relates to the field of workpiece cutting technology, and in particular to a baffle base device for cutting fixed templates. Background Technology

[0002] Before mechanical property testing, rebar samples must be cut to a specific length according to standard requirements. Currently, a Ф400 heavy-duty cutting machine is typically used for this purpose. The operation requires first measuring the sample length, marking the cutting position with a marker, and then cutting along the mark. The entire process includes three steps: measuring the length, marking, and cutting. On average, each sample takes about 2 minutes. Among these steps, measuring the sample length and marking rely on repeated manual operations, which are too cumbersome and laborious, affecting the processing efficiency of sample cutting.

[0003] Therefore, the present invention provides a baffle base device for cutting fixed sample lengths. Summary of the Invention

[0004] The purpose of this invention is to solve at least one technical problem mentioned in the background art. This invention provides a baffle base device for cutting fixed-length samples, comprising a cutting machine body and a cutting auxiliary mechanism;

[0005] The cutting auxiliary mechanism includes a base plate, a positioning plate, and a baffle plate. The positioning plate is located on the upper right of the base plate, and the baffle plate is located on the right side of the positioning plate. An adjusting plate is provided between the baffle plate and the positioning plate. The right side surface of the positioning plate has two adjusting grooves that are adapted to the two adjusting plates respectively. The right end of the adjusting plate is fixedly connected to the left side surface of the baffle plate, and the end of the adjusting plate away from the baffle plate is slidably connected to the inside of the adjusting groove. The upper surface of the positioning plate and one of the two adjusting plates is provided with a scale.

[0006] By using the adjustment plate and adjustment groove together, the position of the baffle plate can be adjusted. With the help of the scale, the baffle plate's blocking position can be precisely adjusted according to the required cutting length.

[0007] By adopting the above technical solution, when in use, the base plate is horizontally inserted into the gap below the cutting machine body until the left side of the positioning plate abuts against the right side of the cutting machine body. Then, the workpiece to be cut is placed in the cutting groove below the cutting blade of the cutting machine body, and the right end of the workpiece abuts against the baffle plate, and cutting can be performed. During this process, the distance between the baffle plate and the cutting groove of the cutting machine body is the length of the workpiece to be cut, thereby achieving equidistant cutting without the need for distance cutting by measurement, drawing lines, or other methods.

[0008] Preferably, the base plate has a storage groove on both the front and back sides. A No. 1 spring is fixedly connected to the inner wall of the storage groove. A limit stop bar is fixedly connected to the end of the No. 1 spring away from the inner wall of the storage groove. A vertical plate is fixedly installed on the upper surface of the base plate. A rotating opening is opened through the surface of the vertical plate. A threaded rod is rotatably connected to the inner wall of the rotating opening. A threaded cylinder is embedded on the right side surface of the positioning plate. The inner wall of the threaded cylinder is threadedly connected to the surface of the threaded rod. Two symmetrical T-shaped sliders are provided on the lower surface of the positioning plate. A T-shaped groove for the T-shaped sliders to slide is opened on the upper surface of the base plate.

[0009] With the setting of spring number one and limit stop bar, after the base plate is inserted into the gap under the cutting machine body, spring number one pushes the limit stop bar to pop out in the storage groove, which plays a limiting role. At the same time, by rotating the threaded rod, under the guidance of the T-shaped slider, the threaded cylinder can drive the positioning plate to move in a direction through the rotation of the threaded rod until the left side of the positioning plate abuts against the right side of the cutting machine body. With the limit stop bar in place, the cutting auxiliary mechanism can be stably assembled with the cutting machine body.

[0010] Preferably, both sides of the limiting stop are provided with guide blocks, and both sides of the inner wall of the receiving groove are provided with guide grooves for the guide blocks to slide.

[0011] By adopting the above technical solution, the limiting stop bar can move in a directional manner within the receiving groove under the guidance of the guide slider.

[0012] Preferably, the left side surface of the positioning plate has a groove, and an anti-slip pad is embedded inside the groove. The anti-slip pad is made of wear-resistant rubber material.

[0013] By using anti-slip pads, the anti-slip pads can increase friction and enhance stability when the positioning plate contacts the cutting machine body, and also protect the surface of the cutting machine body.

[0014] Preferably, each of the two adjusting plates has an installation cavity inside its housing. A backing plate is installed inside the installation cavity. A second spring is fixedly connected to the inner wall of the installation cavity. The other end of the second spring away from the inner wall of the installation cavity is fixedly connected to the surface of the backing plate. An opening is provided in the inner wall of the installation cavity, extending into the interior of the adjusting groove. A positioning tooth block is installed on the other side of the backing plate away from the second spring through the opening. A rack groove matching the positioning tooth block is provided on the inner wall of the adjusting groove adjacent to the opening. Two sliding strip openings extending into the interior of the two installation cavities are respectively provided on the right side surface of the baffle plate. A push plate for pushing the backing plate is slidably connected to the inner wall of the sliding strip opening.

[0015] By setting up the No. 2 spring, the stop plate, and the positioning tooth block, and through the cooperation of the No. 2 spring, the stop plate, and the positioning tooth block, the No. 2 spring pushes the stop plate to make the positioning tooth block engage with the rack groove, thereby positioning the material blocking position of the adjusting plate and the baffle plate, ensuring the stability of subsequent material blocking operations.

[0016] Preferably, a limiting slider is provided on the left side surface of the abutment, and a limiting groove is provided on the left inner wall of the mounting cavity for the limiting slider to slide.

[0017] By adopting the above technical solution, the stop plate can move smoothly within the mounting cavity under the guidance of the limiting slider.

[0018] Preferably, a mounting shell is fixedly installed on the back of the positioning plate. The interior of the mounting shell has a slot and a cavity. An electric push rod is fixedly installed on the inner rear wall of the slot. A push plate is fixedly installed on the telescopic end of the electric push rod. A controller is installed on the right side surface of the mounting shell. A foot switch is provided on the front of the base plate via a connecting wire.

[0019] With the electric push rod and foot switch, after the workpiece is cut, the operator steps on the foot switch, and the controller controls the electric push rod to extend. The electric push rod drives the pusher plate to push the cut workpiece out of the cutting area, which facilitates subsequent continuous cutting operations.

[0020] Preferably, a telescopic airbag is installed on the inner rear wall of the cavity, and a transmission hole is opened on the inner front wall of the cavity, penetrating through the front of the mounting shell. A transmission rod is fixedly connected to the back of the pusher plate through the transmission hole. A pressure plate is fixedly installed at the rear end of the transmission rod. The side of the pressure plate away from the transmission rod is fixedly connected to the front end of the telescopic airbag. A universal tube and an air outlet tube communicating with the inside of the telescopic airbag are respectively embedded on the back of the mounting shell. A dust suction nozzle is installed at the end of the universal tube away from the mounting shell, and a dust collection bag is covered on the surface of the air outlet tube.

[0021] With the design of the telescopic airbag, universal tube, and exhaust duct, when the electric push rod drives the pusher plate to move back and forth to push the material, the pusher plate simultaneously drives the transmission rod and pressure plate to squeeze and stretch the telescopic airbag. When the telescopic airbag is stretched, the dust generated after the workpiece is cut is sucked into the telescopic airbag through the universal tube and the dust suction nozzle. When the pusher plate moves back to its original position, the telescopic airbag is squeezed, and the dust inside is discharged through the exhaust duct and collected by the dust collection bag, thus realizing the dust collection function.

[0022] Preferably, the surfaces of the universal tube and the air outlet tube are respectively provided with a one-way air inlet valve and a one-way air outlet valve.

[0023] By setting up a one-way inlet valve and a one-way outlet valve, the one-way inlet valve ensures that the airflow can only enter the telescopic airbag from the universal tube, and the one-way outlet valve ensures that the airflow can only exit from the telescopic airbag through the outlet pipe, thereby ensuring one-way circulation of suction and dust removal.

[0024] In summary, the present invention has at least one of the following beneficial technical effects:

[0025] 1. The baffle base device for cutting fixed-length samples according to the present invention is used by horizontally inserting the base plate into the gap below the cutting machine body until the left side of the positioning plate abuts against the right side of the cutting machine body. Then, the workpiece to be cut is placed in the cutting groove below the cutter of the cutting machine body, and the right end of the workpiece abuts against the baffle plate, and cutting can be performed. During this process, the distance between the baffle plate and the cutting groove of the cutting machine body is the length of the workpiece to be cut, thereby achieving equidistant cutting without the need for fixed-distance cutting by measurement, drawing lines, or other methods.

[0026] 2. The baffle base device for cutting fixed sample length according to the present invention has a first spring pushing the limiting stop rod to pop out and lock it on the side of the cutting machine to achieve initial limiting. Then, the threaded rod is rotated and the positioning plate is moved by the T-shaped slider until the anti-slip pad on its left side presses against the right side surface of the cutting machine, thereby completing the stable assembly of the auxiliary mechanism and the cutting machine body together with the limiting stop rod.

[0027] 3. The baffle base device for cutting fixed-length samples according to the present invention, after one cut is completed, stepping on the foot switch drives the controller to extend the electric push rod, and the push plate automatically pushes the cut workpiece out of the cutting area. When the push plate moves forward, it stretches the telescopic airbag through the transmission rod and the pressure plate. The one-way air inlet valve opens and the air outlet valve closes, and the cutting dust is sucked in through the universal tube and the dust suction nozzle. When the push plate moves backward and resets, the pressure plate squeezes the airbag, and the dust-laden gas is discharged into the dust collection bag through the air outlet pipe, thereby realizing dust collection and improving the working environment.

[0041] The following combination Figures 1 to 9 The present invention will be further described in detail below.

[0042] Example 1

[0043] Please refer to the following carefully. Figure 1 , Figure 2 A baffle base device for cutting fixed-length samples includes a cutting machine body 1 and a cutting auxiliary mechanism 2. The cutting auxiliary mechanism 2 includes a base plate 201, a positioning plate 202 and a baffle plate 203. The positioning plate 202 is located on the upper right of the base plate 201, and the baffle plate 203 is located on the right side of the positioning plate 202. An adjusting plate 8 is provided between the baffle plate 203 and the positioning plate 202. The right side surface of the positioning plate 202 is provided with two adjusting grooves that are adapted to the two adjusting plates 8 respectively. The right end of the adjusting plate 8 is fixedly connected to the left side surface of the baffle plate 203. The end of the adjusting plate 8 away from the baffle plate 203 is slidably connected to the inside of the adjusting groove. The upper surface of the positioning plate 202 and one of the two adjusting plates 8 are provided with a scale 9.

[0044] By adjusting the plate 8 and the groove, the position of the baffle plate 203 can be adjusted. With the help of the scale 9, the baffle position of the baffle plate 203 can be precisely adjusted according to the required cutting length.

[0045] Specifically, the base plate 201 is horizontally inserted into the gap below the cutting machine body 1 until the left side of the positioning plate 202 abuts against the right side of the cutting machine body 1. Then, the workpiece to be cut is placed in the cutting groove below the cutter of the cutting machine body 1, and the right end of the workpiece abuts against the baffle plate 203, and cutting can be performed. During this process, the distance between the baffle plate 203 and the cutting groove of the cutting machine body 1 is the length of the workpiece to be cut, thereby achieving equidistant cutting without the need for distance cutting by measurement, drawing lines, or other methods.

[0046] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 , Figure 5 The base plate 201 has storage slots on both the front and back. A spring 3 is fixedly connected to the inner wall of the storage slot. A limit stop bar 4 is fixedly connected to the end of the spring 3 away from the inner wall of the storage slot. A vertical plate is fixedly installed on the upper surface of the base plate 201. A rotating opening is opened through the surface of the vertical plate. A threaded rod 5 is rotatably connected to the inner wall of the rotating opening. A threaded cylinder is embedded on the right side surface of the positioning plate 202. The inner wall of the threaded cylinder is threadedly connected to the surface of the threaded rod 5. Two symmetrical T-shaped sliders 6 are provided on the lower surface of the positioning plate 202. A T-shaped groove for the T-shaped sliders 6 to slide is opened on the upper surface of the base plate 201.

[0047] Specifically, by setting up the No. 1 spring 3 and the limiting stop 4, after the base plate 201 is inserted into the gap below the cutting machine body 1, the No. 1 spring 3 pushes the limiting stop 4 to pop out in the storage groove, which plays a limiting role. At the same time, by rotating the threaded rod 5, under the guidance of the T-shaped slider 6, the threaded cylinder can drive the positioning plate 202 to move in a direction through the rotation of the threaded rod 5 until the left side of the positioning plate 202 abuts against the right side of the cutting machine body 1. With the limiting stop 4, the cutting auxiliary mechanism 2 can be stably assembled with the cutting machine body 1.

[0048] Please refer to this carefully. Figure 3 The limit stop bar 4 has guide sliders 7 on both sides of its surface, and the inner walls of both sides of the storage groove have guide grooves for the guide sliders 7 to slide.

[0049] Specifically, under the guidance of the guide slider 7, the limiting stop bar 4 can move in a specific direction within the receiving groove.

[0050] Please refer to this carefully. Figure 2 , Figure 4 The left side surface of the positioning plate 202 has a groove, and an anti-slip pad is embedded inside the groove. The anti-slip pad is made of wear-resistant rubber material.

[0051] Specifically, by setting up anti-slip pads, the anti-slip pads can increase friction and enhance stability when the positioning plate 202 contacts the cutting machine body 1, and also protect the surface of the cutting machine body 1.

[0052] Please refer to this carefully. Figure 6 , Figure 7 Both adjusting plates 8 have mounting cavities inside their housings. A backing plate 10 is installed inside each mounting cavity. A second spring 11 is fixedly connected to the inner wall of the mounting cavity. The other end of the second spring 11 away from the inner wall of the mounting cavity is fixedly connected to the surface of the backing plate 10. An opening is provided in the inner wall of the mounting cavity, extending into the adjusting groove. A positioning tooth block 12 is installed on the other side of the backing plate 10 away from the second spring 11 through the opening. A rack groove 13 matching the positioning tooth block 12 is provided on the inner wall of the adjusting groove adjacent to the opening. Two sliding strip openings extending into the two mounting cavities are respectively provided on the right side surface of the baffle plate 203. A push plate 14 for pushing the backing plate 10 is slidably connected to the inner wall of the sliding strip opening.

[0053] Specifically, through the arrangement of the second spring 11, the abutment plate 10, and the positioning tooth block 12, and through the cooperation of the second spring 11, the abutment plate 10, and the positioning tooth block 12, the second spring 11 pushes the abutment plate 10 to make the positioning tooth block 12 engage with the rack groove 13, thereby positioning the material blocking position of the adjusting plate 8 and the baffle plate 203, ensuring the stability of subsequent material blocking operations.

[0054] Please refer to this carefully. Figure 6 , Figure 7 A limiting slider 15 is provided on the left side surface of the abutment plate 10, and a limiting groove for the limiting slider 15 to slide is provided on the left inner wall of the mounting cavity.

[0055] Specifically, under the guidance of the limiting slider 15, the abutment 10 can move smoothly within the mounting cavity.

[0056] The working principle of this embodiment is as follows:

[0057] In use, the operator inserts the base plate 201 horizontally into the gap below the cutting machine body 1. Once the base plate 201 is in place, the compressed spring 3, under its own elastic force, pushes the limit stop 4 outward from the storage slot and locks it against the side of the cutting machine body 1, achieving initial limiting. Subsequently, the operator rotates the threaded rod 5, and under the guidance of the T-shaped slider 6 and the T-shaped groove, the threaded cylinder drives the positioning plate 202 to move in a specific direction until the anti-slip pad on the left side of the positioning plate 202 is tightly pressed against the cutting machine body. On the right side surface of 1, under the combined action of the limiting stop 4 and the abutment of the positioning plate 202, the entire cutting auxiliary mechanism 2 is stably assembled with the cutting machine body 1. Before cutting, the operator adjusts the position of the baffle plate 203 according to the standard cutting length required for the threaded steel sample. First, manually move the two push plates 14. The push plates 14 push the abutment plate 10 to compress the second spring 11, causing the positioning tooth block 12 to disengage from the rack groove 13. At this time, the adjusting plate 8 can be freely moved to change the position of the baffle plate 203. During the adjustment process, the distance between the baffle plate 203 and the positioning plate 202 is precisely positioned using the scale 9 on the positioning plate 202 and the adjusting plate 8. When the baffle plate 203 moves to the designated position (i.e., the distance between the baffle plate 203 and the cutting groove of the cutting machine is equal to the required sample length; during this process, the distance between the cutting groove of the cutting machine and the positioning plate 202 needs to be measured first), the push plate 14 is released, the second spring 11 is reset, and the abutment plate 10 is pushed to make the positioning tooth block 12 re-engage in the rack groove 13, thereby positioning the baffle plate 203. Position 203 is firmly locked. After completing the above preparations, the operator directly places the threaded steel sample to be cut in the cutting groove below the cutter of the cutting machine body 1, and pushes its right end face to abut against the inner surface of the baffle plate 203. At this time, the fixed distance between the baffle plate 203 and the cutting groove of the cutting machine is the required sample cutting length. After the cutting is completed, the cut sample is taken out, and the end face of the remaining bar is abutted against the baffle plate 203 again, so that the next equal length cutting can be carried out continuously, which greatly simplifies the operation process.

[0058] Example 2

[0059] Compared with Embodiment 1, another embodiment of the present invention is as follows:

[0060] Please refer to this carefully. Figure 2 , Figure 8 , Figure 9 A mounting shell 16 is fixedly installed on the back of the positioning plate 202. The interior of the mounting shell 16 has a slot and a cavity. An electric push rod 17 is fixedly installed on the inner rear wall of the slot. A push plate 18 is fixedly installed on the telescopic end of the electric push rod 17. A controller 19 is installed on the right side surface of the mounting shell 16. A foot switch 20 is set at the front of the base plate 201 through a connecting wire. Both the electric push rod 17 and the foot switch 20 are electrically connected to the controller 19.

[0061] Specifically, through the setting of electric push rod 17 and foot switch 20, after the workpiece is cut, the operator steps on foot switch 20, the controller 19 controls the electric push rod 17 to extend, and the electric push rod 17 drives the pusher plate 18 to push the cut workpiece out of the cutting area, which is convenient for subsequent continuous cutting operations.

[0062] Please refer to this carefully. Figure 8 , Figure 9 The inner rear wall of the cavity is equipped with a telescopic airbag 21, and the inner front wall of the cavity is provided with a transmission hole that extends through the front of the mounting shell 16. The back of the pusher plate 18 is fixedly connected to the transmission rod 22 through the transmission hole. The rear end of the transmission rod 22 is fixedly installed with a pressure plate. The side of the pressure plate away from the transmission rod 22 is fixedly connected to the front end of the telescopic airbag 21. The back of the mounting shell 16 is respectively embedded with a universal tube 23 and an air outlet tube 24 that communicate with the inside of the telescopic airbag 21. A dust suction nozzle 25 is installed at the end of the universal tube 23 away from the mounting shell 16, and a dust collection bag 26 is covered on the surface of the air outlet tube 24.

[0063] Specifically, through the arrangement of the telescopic airbag 21, the universal tube 23, and the exhaust pipe 24, when the electric push rod 17 drives the pusher plate 18 to move back and forth to push the material, the pusher plate 18 simultaneously drives the transmission rod 22 and the pressure plate to squeeze and stretch the telescopic airbag 21. When the telescopic airbag 21 is stretched, the dust generated after the workpiece is cut is sucked into the telescopic airbag 21 through the universal tube 23 and the dust suction nozzle 25. When the pusher plate 18 moves back to its original position, the telescopic airbag 21 is squeezed, and the dust inside is discharged through the exhaust pipe 24 and collected by the dust collection bag 26, thereby realizing the dust collection function.

[0064] Please refer to this carefully. Figure 9 The surfaces of the universal tube 23 and the air outlet tube 24 are respectively provided with a one-way air inlet valve and a one-way air outlet valve.

[0065] Specifically, by setting up a one-way air inlet valve and a one-way air outlet valve, the one-way air inlet valve ensures that the airflow can only enter the telescopic airbag 21 from the universal tube 23, and the one-way air outlet valve ensures that the airflow can only be discharged from the telescopic airbag 21 through the air outlet pipe 24, thereby ensuring the one-way circulation of suction and dust removal.

[0066] The working principle of this embodiment is as follows:

[0067] After a cut is completed, the operator presses the foot switch 20, and the controller 19 controls the electric push rod 17 to extend, driving the pusher plate 18 to automatically push the cut workpiece out of the cutting area, facilitating the next cut quickly. As the pusher plate 18 moves forward, it stretches the telescopic airbag 21 via the transmission rod 22 and the pressure plate. At this time, the one-way inlet valve opens and the one-way outlet valve closes, drawing the dust generated during cutting into the telescopic airbag 21 through the universal tube 23 and the suction nozzle 25. When the pusher plate 18 moves backward and resets under the drive of the electric push rod 17, the pressure plate squeezes the telescopic airbag 21, opening the one-way outlet valve and closing the one-way inlet valve. The dust-laden gas inside the airbag is discharged into the dust collection bag 26 through the exhaust pipe 24, achieving dust collection and effectively improving the working environment.
