Description

Technical Field

[0001] The invention relates to the technical field of punching devices, and in particular to a punching machine used for roller processing. Background Art

[0002] Rollers are key components in rolling equipment and are mainly used for pressure processing of metals, such as rolling of steel and nonferrous metals, as well as calendering in industries such as papermaking and plastics. During the assembly process of the rolls, it is necessary to use a punching machine to process some positioning holes and assembly holes on the rolls to ensure the correct installation and positioning of the rolls in the rolling mill.

[0003] A punching machine in the prior art, such as a punching machine for roller processing disclosed in a Chinese patent document with authorization announcement number CN215545077U, can increase the clamping effect of the roller during processing by setting two sets of roller clamps, and can clamp the roller more efficiently; an electrically driven three-jaw chuck is used for rapid clamping and improved work efficiency. Compared with a manual chuck, an electric chuck can automatically center and clamp the workpiece in an instant with just the push of a button, and the clamping force is stable and adjustable; by placing the drill bit and the roller clamp on the same horizontal plane, the drilling accuracy can be improved, and the detachable drill bit can be replaced with another drill bit as needed, which is more convenient to use.

[0004] However, if the debris generated during the drilling process of the punching machine used for roller processing in the prior art is not effectively discharged, it is easy to accumulate between the drill bit and the hole wall. Excessive accumulation of debris will significantly increase the resistance of the drill bit during rotation, thereby affecting the drilling quality, resulting in increased hole wall roughness, reduced drilling accuracy and other problems. In addition, when the drill bit is subject to too much resistance, it may also cause the drill bit to twist off, which will not only damage the drill bit, but also cause the roller processing to be interrupted, or even damage the machine tool. Summary of the invention

[0005] The present invention provides a punching machine for roller processing, aiming to solve the problem in the related art that the debris accumulated between the drill bit and the hole wall in the punching machine for roller processing increases the resistance of the drill bit when rotating, thereby affecting the drilling quality and increasing the risk of the drill bit twisting off.

[0006] The present invention provides a punching machine for roller processing, which adopts the following technical solution: A punching machine for roller processing, comprising a machine body, a clamping mechanism arranged on the machine body for fixing the roller, and a punching mechanism arranged on the machine body for punching holes in the roller, wherein the punching mechanism comprises: A feed seat and a feed driver, wherein the feed seat is movably mounted on the machine body, and the feed driver is mounted on the machine body and connected to the feed seat to drive the feed seat to move along the feeding direction; An adjusting cylinder and a drill bit, wherein the adjusting cylinder is mounted on the feed seat through a first spiral groove, and the drill bit is rotatably mounted on one end of the adjusting cylinder facing the clamping mechanism; A transmission member and a rotary driver, wherein the transmission member is installed at the end of the drill bit close to the adjusting cylinder and comprises a scroll spring for detecting the resistance of the drill bit, a guide plate connected to the inner end of the scroll spring and driving the scroll spring to move along the feeding direction, the rotary driver is installed on the feed seat and connected to the inner end of the scroll spring, the outer end of the scroll spring is connected to the drill bit to drive the drill bit to rotate, and the guide plate is installed on the drill bit through a second spiral groove, so that when the scroll spring is compressed, the guide plate can drive the scroll spring to move to the adjusting cylinder, so that the outer end of the scroll spring is connected to the adjusting cylinder to drive the adjusting cylinder to rotate, and then the adjusting cylinder drives the drill bit to retract.

[0007] By adopting the above technical solution, through the setting of the scroll spring and the adjusting cylinder, it is possible to detect the resistance encountered by the drill bit during the drilling process, and trigger the drill bit to stop rotating and retract the drill bit when the resistance is too large, thereby automatically protecting the drill bit, effectively reducing the risk of the drill bit twisting off, and improving the safety of the processing process. It can also reduce the problems of increased hole wall roughness and reduced drilling accuracy caused by excessive resistance, thereby improving the drilling quality. In addition, the automated resistance detection and drill bit retraction mechanism reduce manual intervention and improve the operating efficiency of the punching machine.

[0008] Furthermore, the drill bit comprises a rotating cylinder rotatably mounted on the adjusting cylinder, a drill body fixed to an end of the rotating cylinder away from the adjusting cylinder, and the transmission member is mounted in the rotating cylinder.

[0009] Furthermore, the inner wall of the rotating cylinder is provided with the second spiral groove and an annular groove, the annular groove is connected to one end of the second spiral groove close to the adjusting cylinder, and the outer wall of the guide plate is fixed with a guide block which is movably assembled in the second spiral groove and can enter the annular groove.

[0010] Furthermore, the transmission member also includes an elastic telescopic tube connected between the spiral spring and the guide plate, and the elastic telescopic tube is used to apply elastic force to the guide plate to move the guide plate away from the spiral spring so that the guide block on the guide plate can enter the second spiral groove from the annular groove.

[0011] Furthermore, a first straight groove is provided on the inner wall of the rotating cylinder, the first straight groove has a first opening near the end of the adjusting cylinder, a spring block is provided at the first opening of the first straight groove, the outer end of the spiral spring is installed in the first straight groove through a clamping block, and can pass over the spring block and enter the adjusting cylinder.

[0012] Furthermore, the elastic block has a first inclined surface on a side close to the adjustment tube and a second inclined surface on a side away from the adjustment tube, and an inclination angle of the first inclined surface is smaller than an inclination angle of the second inclined surface.

[0013] With the above technical solution, the setting of the spring block is used to assist in resistance detection, so that the block of the spiral spring can be smoothly switched between the rotating cylinder and the adjusting cylinder, ensuring that the block of the spiral spring remains in the correct position. When the resistance of the drill bit increases to a certain extent, the block of the spiral spring can pass over the spring block and enter the adjusting cylinder. When resetting, since the inclination angle of the first inclined surface is smaller than the inclination angle of the second inclined surface, the block of the spiral spring can easily pass over the spring block and enter the rotating cylinder. The setting of the spring block can also buffer part of the resistance through its own elastic deformation when the resistance of the drill bit is too large, thereby protecting the drill bit.

[0014] Furthermore, a second straight groove is provided on the inner wall of the adjusting cylinder, and the second straight groove has a second opening at the end close to the rotating cylinder. The second straight groove is provided with an inclined surface at the second opening, and the inclined surface is inclined outward from the first opening toward the second opening, and the blocking block can enter the second straight groove along the inclined surface.

[0015] By adopting the above technical solution, the distances from the first straight groove and the second straight groove to the rotation axis of the drill bit are different, so that the clamping block will only cooperate with the second straight groove after it is completely separated from the first straight groove, which is beneficial to ensure the reliability of transmission switching, avoid jamming or partial cooperation of the clamping block during the switching process, and improve the stability of equipment operation.

[0016] Furthermore, the transmission member also includes a transmission cylinder, the inner end of the volute spring is fixed on the transmission cylinder, and the rotation driver is connected to the volute spring through the transmission cylinder to drive the volute spring to rotate.

[0017] Furthermore, the outer wall of the adjusting cylinder is provided with a plurality of prismatic protrusions distributed along the circumference of the adjusting cylinder, the first spiral groove is opened on the feed seat, and the outer wall of the adjusting cylinder is provided with a spiral protrusion matched with the first spiral groove.

[0018] By adopting the above technical solution, the prismatic protrusion is used to increase the friction between the hand and the adjusting cylinder and provide a better grip, so that the staff can manually rotate the adjusting cylinder to reset it; the cooperation between the spiral protrusion and the first spiral groove can provide axial and radial positioning at the same time, making the adjusting cylinder more stable during movement.

[0019] Furthermore, the punching mechanism also includes a telescopic water pipe arranged on the feed seat and connected to the drill bit through the adjustment tube, one end of the telescopic water pipe is connected to the outside, and the other end is connected to the flushing hole opened at the end of the drill bit.

[0020] By adopting the above technical solution, the telescopic water pipe is used to pass the flushing liquid to flush the drilling hole of the roller and the debris at the end of the drill bit, thereby ensuring the cleanliness of the drilling hole and facilitating the maintenance of the drill bit.

[0021] The beneficial effect of a punching machine for roller processing provided by the present invention is that through the setting of the scroll spring and the adjusting cylinder, the resistance encountered by the drill bit during the punching process can be detected, and when the resistance is too large, the drill bit is triggered to stop rotating and retract the drill bit, thereby automatically protecting the drill bit, effectively reducing the risk of the drill bit twisting off, improving the safety of the processing process, and can reduce the problems of increased hole wall roughness and reduced drilling accuracy caused by excessive resistance, thereby improving the drilling quality.

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 5As shown, an embodiment of the punching machine for roller processing of the present invention includes a body 10, a clamping mechanism 110 and a punching mechanism 120, wherein the clamping mechanism 110 and the punching mechanism 120 are respectively arranged on the body 10, wherein the clamping mechanism 110 is used to fix the roller 130, and the punching mechanism 120 is used to punch holes in the roller 130.

[0030] like Figures 1 to 3 As shown, the punching mechanism 120 includes a feed seat 20 , a feed driver, a transmission member 30 , a rotary driver, an adjustment cylinder 50 , a drill bit 60 and a telescopic water pipe 70 .

[0031] The feed seat 20 is movably mounted on the body 10, and has a mounting hole on one side of the feed seat 20 facing the clamping mechanism 110, and the inner wall of the mounting hole is provided with a first spiral groove 210. The feed driver is mounted on the body 10 and connected to the feed seat 20 to drive the feed seat 20 to move along the feeding direction.

[0032] like Figures 2 to 4 As shown, the adjustment cylinder 50 is installed in the mounting hole of the feed seat 20, and the outer wall of the adjustment cylinder 50 is provided with a spiral protrusion 530 and a prismatic protrusion 520. The spiral protrusion 530 cooperates with the first spiral groove 210. The thread rotation direction of the first spiral groove 210 determines the moving direction of the adjustment cylinder 50 under a specific rotation direction. The setting of the spiral protrusion 530 can provide axial and radial positioning at the same time, so that the adjustment cylinder 50 is more stable during movement. There are multiple prismatic protrusions 520 distributed along the circumference of the adjustment cylinder 50, which are used to increase the friction between the hand and the adjustment cylinder 50 and provide a better grip, so that the staff can manually rotate the adjustment cylinder 50 to reset the adjustment cylinder 50. The inner wall of the adjustment cylinder 50 is provided with a second straight groove 510 extending along the feeding direction.

[0033] The drill bit 60 includes a rotating cylinder 610 rotatably mounted on the adjusting cylinder 50, and a drill body 620 fixed to the end of the rotating cylinder 610 away from the adjusting cylinder 50. The inner wall of the rotating cylinder 610 is provided with a second spiral groove 611, an annular groove 612 and a first straight groove 613. The annular groove 612 is connected to an end of the second spiral groove 611 close to the adjusting cylinder 50. The first straight groove 613 is located on a side of the annular groove 612 away from the second spiral groove 611, the first straight groove 613 extends along the feeding direction, and the end of the first straight groove 613 close to the adjusting cylinder 50 has a first opening. The end of the second straight groove 510 close to the rotating cylinder 610 has a second opening, and the second straight groove 510 is provided with an inclined surface 511 at the second opening, and the inclined surface 511 is inclined outward from the first opening to the second opening. The first straight slot 613 is provided with a spring block 614 at the first opening. The spring block 614 has a first inclined surface on the side close to the adjustment cylinder 50 and a second inclined surface on the side away from the adjustment cylinder 50. The inclination angle of the first inclined surface is smaller than the inclination angle of the second inclined surface. A flushing hole is provided at the end of the drill body 620.

[0034] like Figures 3 to 5 As shown, the transmission member 30 is installed in the rotating cylinder 610 and includes a transmission cylinder 310, a spiral spring 320, an elastic telescopic cylinder 330, a guide plate 340 and a connecting plate 350.

[0035] The transmission cylinder 310 includes an inner sleeve and an outer sleeve which are sleeved with each other. The inner wall of the outer sleeve is provided with a limiting groove along the feeding direction. The outer wall of the inner sleeve has a limiting protrusion extending along the feeding direction and slidingly cooperating with the limiting groove, so that the inner sleeve and the outer sleeve can be retracted and the inner sleeve and the outer sleeve rotate synchronously. The rotary driver is installed on the feed seat 20 and connected to the outer sleeve of the transmission cylinder 310 to drive the transmission cylinder 310 to rotate.

[0036] The scroll spring 320 is used to detect the resistance of the drill bit 60. The inner end of the scroll spring 320 is fixed on the inner sleeve of the transmission cylinder 310, and the outer end of the scroll spring 320 is fixed with a clamping block 321. The clamping block 321 is installed in the first straight groove 613 to drive the drill bit 60 to rotate, so as to perform the drilling work. When the drill bit 60 is subjected to excessive resistance, the scroll spring 320 is compressed, and the clamping block 321 can pass over the spring block 614 and enter the second straight groove 510 of the adjustment cylinder 50 to drive the adjustment cylinder 50 to rotate, thereby making the rotation direction of the adjustment cylinder 50 match the rotation direction of the first spiral groove 210, so that the adjustment cylinder 50 drives the drill bit 60 to retract along the axial direction.

[0037] It should be noted that the setting of the spring block 614 is used to assist in resistance detection, so that the block 321 of the spiral spring 320 can be smoothly switched between the rotating cylinder 610 and the adjusting cylinder 50, ensuring that the block 321 of the spiral spring 320 remains in the correct position; the setting of the spring block 614 can also buffer part of the resistance through its own elastic deformation when the resistance encountered by the drill bit 60 is too large, thereby protecting the drill bit 60.

[0038] The connecting plate 350 is fixed on the inner sleeve of the transmission cylinder 310 and is located on a side of the spiral spring 320 close to the drill body 620 .

[0039] The guide plate 340 is used to drive the spiral spring 320 to move along the feeding direction, so that the block 321 at the outer end of the spiral spring 320 can move between the first straight groove 613 and the second straight groove 510. The guide plate 340 is located on the side of the connecting plate 350 close to the drill body 620, and is connected to the connecting plate 350 through the elastic telescopic cylinder 330. The outer wall of the guide plate 340 is fixed with a guide block 341 that is movably assembled in the second spiral groove 611 and can enter the annular groove 612. The elastic telescopic cylinder 330 is used to apply an elastic force to the guide plate 340 to keep the guide plate 340 away from the spiral spring 320, so that the guide block 341 on the guide plate 340 can enter the second spiral groove 611 from the annular groove 612.

[0040] It should be noted that the distances from the first straight groove 613 and the second straight groove 510 to the rotation axis of the drill bit 60 are different, so that the clamping block 321 will only cooperate with the second straight groove 510 after it is completely separated from the first straight groove 613, which is beneficial to ensure the reliability of transmission switching, avoid jamming or partial cooperation of the clamping block 321 during the switching process, and improve the stability of equipment operation.

[0041] The telescopic water pipe 70 is arranged on the feed seat 20 and passes through the adjustment cylinder 50 to connect the drill bit 60. One end of the telescopic water pipe 70 is connected to the outside, and the other end is connected to the flushing hole opened at the end of the drill bit 60. The telescopic water pipe 70 is used to pass the flushing liquid to flush the debris at the drill hole of the roller 130 and the end of the drill bit 60, so as to ensure the cleanliness of the drill hole and facilitate the maintenance of the drill bit 60.

[0042] The working process of the punching machine for roller processing of the present invention comprises the following steps: The first step is to clamp and drill. The roller 130 to be drilled is fixed on the clamping mechanism 110. The feed driver drives the feed seat 20 to approach the roller 130 along the feed direction. The block 321 at the outer end of the spiral spring 320 is located in the first straight groove 613. The rotary driver drives the transmission cylinder 310 to rotate. The transmission cylinder 310 drives the drill bit 60 to rotate through the spiral spring 320, and the drill bit 60 drills the roller 130.

[0043] The second step is resistance detection. Under normal circumstances, the scroll spring 320 maintains a certain preload and is balanced with the feed force of the drill bit 60. When the resistance of the drill bit 60 gradually increases, the scroll spring 320 begins to be compressed, and the inner end of the scroll spring 320 rotates relative to the outer end, that is, the guide plate 340 rotates relative to the rotating cylinder 610, and the guide block 341 on the guide plate 340 moves in the second spiral groove 611, so that the guide plate 340 drives the scroll spring 320 to move toward the adjustment cylinder 50. When the resistance of the drill bit 60 is too large, the guide block 341 on the guide plate 340 enters the annular groove 612 along the second spiral groove 611, and the guide plate 340 drives the scroll spring 320 to continue to move toward the adjustment cylinder 50, so that the block 321 at the outer end of the scroll spring 320 can pass over the spring block 614 and enter the adjustment cylinder 50, and the scroll spring 320 no longer drives the drill bit 60 to rotate, and the drill bit 60 stops rotating.

[0044] The third step is to protect the retraction. The transmission cylinder 310 rotates continuously under the drive of the rotary driver, and drives the spiral spring 320 to rotate continuously. After the spiral spring 320 enters the adjusting cylinder 50, the elastic force stored in the spiral spring 320 during the resistance detection process makes the block 321 tend to move outward. During the continuous rotation of the spiral spring 320, the block 321 can extend into the second straight groove 510, so that the spiral spring 320 drives the adjusting cylinder 50 to rotate, so that the adjusting cylinder 50 drives the drill bit 60 to retract relative to the feed seat 20. During the process of the adjusting cylinder 50 driving the drill bit 60 to retract, the switch of the rotary driver can be automatically triggered, so that the rotary driver stops driving the transmission cylinder 310 to rotate, thereby cutting off the power supply, which is convenient for the staff to check the drill bit 60 and the drilling condition.

[0045] The fourth step is to flush the debris. While the drill bit 60 is retracted, flushing liquid is introduced into the telescopic water pipe 70 through an external flushing liquid pressure pump. The flushing liquid is sprayed toward the drilling position through the flushing hole at the end of the drill bit 60 via the telescopic water pipe 70 to flush away the debris at the drilling position of the roller 130 and the end of the drill bit 60.

[0046] The fifth step is manual reset. The staff manually rotates the adjusting cylinder 50 so that the adjusting cylinder 50 extends relative to the feed seat 20. The spiral spring 320 rotates driven by the adjusting cylinder 50. Due to the elastic force of the elastic telescopic cylinder 330 on the guide plate 340, the guide block 341 on the guide plate 340 can enter the second spiral groove 611 from the annular groove 612. The rotation of the spiral spring 320 drives the guide block 341 on the guide plate 340 to move along the second spiral groove 611. Under the guidance of the second spiral groove 611, the guide plate 340 drives the spiral spring 320 away from the adjusting cylinder 50. The block 321 at the outer end of the spiral spring 320 passes over the spring block 614 and enters the first straight groove 613 of the rotating cylinder 610 to complete the reset.

[0047] In this way, the punching machine for roller processing of the present invention can detect the resistance encountered by the drill bit 60 during the punching process through the arrangement of the spiral spring 320 and the adjusting cylinder 50, and trigger the drill bit 60 to stop rotating and retract the drill bit 60 when the resistance is too large, thereby automatically protecting the drill bit 60, effectively reducing the risk of the drill bit 60 twisting off, improving the safety of the processing process, and reducing the problems of increased hole wall roughness and reduced drilling accuracy caused by excessive resistance, thereby improving the drilling quality. In addition, the automated resistance detection and drill bit 60 retraction mechanism reduce manual intervention and improve the operating efficiency of the punching machine.
