An alloy steel plate blanking device

Abstract

The present invention discloses an alloy steel plate blanking device, belonging to the technical field of alloy blanking. It includes a main body device for blanking alloy steel strips into alloy steel plates. A pushing device is arranged on the main body device for pushing out the blanked alloy steel plates. A winding device is arranged beside the main body device for winding the blanked alloy steel strips. The punch mechanism provided in the present invention uses two pre-punches and a blanking head to perform multiple blankings on the alloy steel strip. Through two pre-blankings, the alloy strip can be processed first to prevent the blanking head from blanking the alloy strip into a steel plate at one time. At the same time, by setting a buffer mechanism, the blanking head and the pressing block are further protected. The alloy strip is wound by driving the winding roller, instead of driving the alloy strip to wind by a winding wheel, effectively avoiding the situation that continuous and precise processing cannot be carried out when more and more alloy strips are wound on the winding disc and the rotation speed of the winding disc remains unchanged.

Description

Technical Field

[0001] The present invention relates to the technical field of alloy blanking, and particularly relates to an alloy steel plate blanking device. Background Art

[0002] Alloy plate blanking is a process of cutting and processing alloy plates through stamping equipment. This process is usually used to manufacture parts that require precise dimensions and shapes. Generally, the pre-prepared alloy plates are placed on a punching press, and the punch and die on the punching press are installed. Through the action of the punching press, the punch presses down, causing the die to blank the alloy plate. Usually, alloy strips are blanked to obtain alloy plates. When the blanking device in the prior art blanks, the blanking head usually directly contacts the bottom plate hard, which will damage the blanking head and the bottom plate. At the same time, the one-time blanking forming will also accelerate the wear of the cutting tool. When winding, when more and more alloy strips are wound on the winding reel and the rotation speed of the winding reel remains unchanged, the winding speed will become slower and slower, unable to meet the requirements of continuous and precise processing. Summary of the Invention

[0003] For the above technical problems, the technical solution adopted by the present invention is: an alloy steel plate blanking device, including a main body device. The main body device includes a housing. The main body device is used to blank alloy steel strips into alloy steel plates. A pushing device is arranged on the main body device. The pushing device includes a descending rack. The pushing device is used to push out the blanked alloy steel plates. A winding device is arranged beside the main body device. The winding device includes a winding frame. The winding device is used to wind the blanked alloy steel strips.

[0004] Further, the main body device includes a base fixedly installed on the housing. An outlet slope is fixedly installed on the base. A feeding roller and a discharging roller are rotatably installed on the base. The alloy steel strip is located on the feeding roller and the discharging roller.

[0005] Further, a blanking mechanism is arranged on the housing. The blanking mechanism includes a heavy turntable rotatably installed on the housing. A guiding frame is fixedly installed on the housing. A rotating rod is rotatably installed on the heavy turntable. A lifting block is rotatably installed on the rotating rod. The lifting block is slidably installed with the guiding frame. A connecting block is fixedly installed on the lifting block. A pressing frame is fixedly installed on the connecting block. An inner transmission wheel and an outer transmission wheel are fixedly installed on the heavy turntable. A horizontal transmission belt is wound around the outer transmission wheel. A motor is fixedly installed on the housing. A motor gear is fixedly installed on the motor shaft of the motor. An inclined transmission belt is wound between the motor gear and the inner transmission wheel.

[0006] Further, a punch mechanism is provided on the lower pressing frame. The punch mechanism includes three sets of guide posts fixedly installed on the lower pressing frame. A front pre-punch, a rear pre-punch, and a blanking head are fixedly installed below the lower pressing frame. Teeth are provided on the four sides of the front pre-punch and the rear pre-punch, and the teeth on the four sides of the front pre-punch are arranged staggeredly with the teeth on the four sides of the rear pre-punch. A blanking cutter is provided at the bottom of the blanking head.

[0007] Further, three buffer mechanisms are provided on the base, which are respectively arranged below the front pre-punch, the rear pre-punch, and the blanking head. The buffer mechanism includes a lower fixed block fixedly installed on the base. The guide post is slidably installed with the lower fixed block. A bottom box is fixedly installed on the lower fixed block. An exhaust hole is provided on the bottom box. A lower pressing block is slidably installed in the bottom box. A lower pressing column is fixedly installed at the bottom of the lower pressing block. The lower pressing column is slidably installed with the bottom box. A compression spring for the pressing column is provided between the lower pressing block and the bottom box.

[0008] The alloy steel strip passes through the feeding idler roller. At the same time, the alloy steel strip is located between the front pre-punch, the rear pre-punch, the blanking head, and the lower pressing block. Subsequently, the alloy steel strip passes through the discharging idler roller and is fixed to the winding device. The motor rotates to drive the motor gear to rotate, drives the inner transmission wheel and the outer transmission wheel to rotate through the inclined transmission belt, drives the transmission gear to rotate through the horizontal transmission belt. At the same time, the inner transmission wheel drives the heavy turntable to rotate, and the rotation of the heavy turntable drives the rotating rod to rotate, thereby driving the lifting block to lift and lower along the guide frame, thereby driving the connecting block and the lower pressing frame to lift and lower, thereby driving the front pre-punch, the rear pre-punch, and the blanking head to lift and lower. The front pre-punch and the rear pre-punch perform pre-blanking on the alloy steel strip below them. Finally, the alloy steel strip is blanked by the blanking head and the blanking cutter. The blanked steel plate is pushed out by the pushing device and leaves along the discharging slope. Whenever the lower pressing frame drives the front pre-punch, the rear pre-punch, and the blanking head to descend, the alloy steel strip does not move. When the front pre-punch, the rear pre-punch, and the blanking head rise, the alloy steel strip moves forward one station. The part originally located below the front pre-punch moves below the rear pre-punch, and the part originally located below the rear pre-punch moves below the blanking head.

[0009] When the front pre-punch, the rear pre-punch, or the blanking head punches the alloy steel strip downward, the front pre-punch, the rear pre-punch, or the blanking head presses the alloy steel strip onto the lower pressing block, and at the same time drives the lower pressing block to descend. The compression spring for the pressing column is compressed, and buffering is performed through the compression spring for the pressing column to prevent damage to the front pre-punch, the rear pre-punch, or the blanking head and the lower pressing block. The exhaust hole is used for exhausting and relieving pressure.

[0010] Further, the pushing device includes a descending rack fixedly installed on the lower pressing frame. A side fixed plate is fixedly installed on the base. A gear rack is fixedly installed on the side fixed plate. A middle transfer gear is rotatably installed on the gear rack. A pushing plate is slidably installed on the side fixed plate. A pushing rack is fixedly installed on the pushing plate. The descending rack meshes with the middle transfer gear, and the middle transfer gear meshes with the pushing rack. A pushing rod is fixedly installed on the pushing plate.

[0011] When the pressing frame and the punching head descend, they will also drive the descending rack to descend, thereby driving the intermediate gear to rotate, and then driving the pushing plate to slide along the side fixing plate through the pushing rack, thereby driving the pushing rod to move to the left side of the pressing block. When the punching head presses down, at this time, the pushing rod is located on the left side of the punching head. When the pressing frame and the punching head rise, the intermediate gear is driven to rotate in the reverse direction by the descending rack, and then the pushing rod is driven to slide towards the discharging slope through the pushing rack and the pushing plate. The alloy steel plate punched by the punching head is pushed onto the discharging slope by the pushing rod.

[0012] Further, the winding device includes a winding wheel and a transmission wheel rotatably installed on the winding frame. A winding roller is rotatably installed on the winding frame. The end of the alloy steel strip passes through the transmission wheel and the winding roller and is fixed on the winding wheel. A driven gear is fixedly installed on the winding roller. A transmission gear is rotatably installed on the winding frame. A semi-tooth gear is fixedly installed on the transmission gear. The semi-tooth gear meshes with the driven gear. A horizontal transmission belt is wound around the transmission gear and the outer transmission wheel.

[0013] Further, a belt pressing mechanism is arranged on the winding frame. The belt pressing mechanism includes a heavy pressing rotating frame rotatably installed on the winding frame. A pressing wheel is rotatably installed on the heavy pressing rotating frame. The gravity of the heavy pressing rotating frame causes the pressing wheel to press the alloy steel strip on the winding roller.

[0014] The horizontal transmission belt drives the transmission gear and the semi-tooth gear to rotate. The semi-tooth gear drives the driven gear to rotate periodically. When the toothed part of the semi-tooth gear contacts the driven gear, it drives the driven gear to rotate. When the toothless part of the semi-tooth gear cooperates with the driven gear, it will not drive the driven gear to rotate. The rotation of the driven gear drives the winding roller to rotate, thereby driving the alloy steel strip to be wound onto the winding wheel. The heavy pressing rotating frame makes the pressing wheel always press the alloy steel strip on the winding roller. Using the winding roller to drive the alloy steel strip to be wound can keep the winding speed of the alloy steel strip constant.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The punching head mechanism provided by the present invention uses two pre-punching heads and a punching head to punch the alloy steel strip multiple times. Through two pre-punchings, the alloy strip can be processed first to prevent the punching head from punching the alloy strip into a steel plate at one time, which causes relatively large wear to the punching head. At the same time, by setting a buffer mechanism, the punching head and the pressing block are further protected; (2) The pushing device provided by the present invention can push out the alloy steel plate punched by the punching head after each descent of the pressing frame, with high automation; (3) The winding device provided by the present invention drives the alloy strip to be wound by the winding roller instead of the winding wheel, effectively avoiding the situation that when more and more alloy steel strip is wound on the winding disc and the rotation speed of the winding disc remains unchanged, the winding speed of the alloy steel strip will become slower and slower, resulting in the inability to continuously and accurately process.

A motor gear 128 is fixedly mounted on the motor shaft of the motor 127. An inclined transmission belt 126 is wound between the motor gear 128 and the inner transmission wheel 123.

[0033] As Figures 2 - 8 shown, a punch mechanism is provided on the pressing frame 106. The punch mechanism includes three groups of guide posts 109 fixedly mounted on the pressing frame 106. A front pre-punch 115, a rear pre-punch 116 and a blanking head 117 are fixedly mounted below the pressing frame 106. Teeth are provided on the four sides of the front pre-punch 115 and the rear pre-punch 116. The teeth on the four sides of the front pre-punch 115 are arranged staggered with the teeth on the four sides of the rear pre-punch 116. A blanking cutter 122 is provided at the bottom of the blanking head 117.

[0034] As Figures 2 - 8 shown, three buffer mechanisms are provided on the base 107, which are respectively arranged below the front pre-punch 115, the rear pre-punch 116 and the blanking head 117. The buffer mechanism includes a lower fixing block 111 fixedly mounted on the base 107. The guide post 109 is slidably mounted with the lower fixing block 111. A bottom box 110 is fixedly mounted on the lower fixing block 111. An exhaust hole 121 is provided on the bottom box 110. A lower pressing block 118 is slidably mounted in the bottom box 110. A lower pressing column 119 is fixedly mounted at the bottom of the lower pressing block 118. The lower pressing column 119 is slidably mounted with the bottom box 110. A compression spring 120 is provided between the lower pressing block 118 and the bottom box 110.

[0035] The alloy steel strip 4 passes through the feeding idler 113. Meanwhile, the alloy steel strip 4 is located between the front pre-punch 115, the rear pre-punch 116, the punching head 117 and the lower pressing block 118. Subsequently, the alloy steel strip 4 passes through the discharging idler 114 and is fixed to the winding device. The motor 127 rotates to drive the motor gear 128 to rotate. The inner transmission wheel 123 and the outer transmission wheel 124 are driven to rotate through the inclined transmission belt 126. The transmission gear 308 is driven to rotate through the horizontal transmission belt 125. Meanwhile, the inner transmission wheel 123 drives the heavy turntable 102 to rotate. The rotation of the heavy turntable 102 drives the rotating rod 103 to rotate, thereby driving the lifting block 104 to lift along the guide frame 105, thus driving the connecting block 108 and the lower pressing frame 106 to lift, thereby driving the front pre-punch 115, the rear pre-punch 116 and the punching head 117 to lift. The front pre-punch 115 and the rear pre-punch 116 perform pre-punching on the alloy steel strip 4 below them. Finally, the alloy steel strip 4 is punched by the punching head 117 and the punching cutter 122. The punched steel plate is pushed out by the pushing device and leaves along the discharging slope 112. Whenever the lower pressing frame 106 drives the front pre-punch 115, the rear pre-punch 116 and the punching head 117 to descend, the alloy steel strip 4 does not move. When the front pre-punch 115, the rear pre-punch 116 and the punching head 117 rise, the alloy steel strip 4 moves forward by one station. The part originally located below the front pre-punch 115 moves below the rear pre-punch 116, and the part originally located below the rear pre-punch 116 moves below the punching head 117.

[0036] When the front pre-punch 115, the rear pre-punch 116 or the punching head 117 punches the alloy steel strip 4 downward, the front pre-punch 115, the rear pre-punch 116 or the punching head 117 presses the alloy steel strip 4 onto the lower pressing block 118, and at the same time drives the lower pressing block 118 to descend. The compression spring 120 of the pressure column is compressed, and buffering is carried out through the compression spring 120 of the pressure column to prevent damage to the front pre-punch 115, the rear pre-punch 116 or the punching head 117 and the lower pressing block 118. The exhaust hole 121 is used for exhausting and relieving pressure.

[0037] As Figure 9 、 Figure 10 shown, the pushing device includes a descending rack 201 fixedly installed on the lower pressing frame 106. A side fixing plate 202 is fixedly installed on the base 107. A gear rack 203 is fixedly installed on the side fixing plate 202. A transfer gear 204 is rotatably installed on the gear rack 203. A pushing plate 206 is slidably installed on the side fixing plate 202. A pushing rack 205 is fixedly installed on the pushing plate 206. The descending rack 201 meshes with the transfer gear 204, and the transfer gear 204 meshes with the pushing rack 205. A pushing rod 207 is fixedly installed on the pushing plate 206.

[0038] When the pressing frame 106 and the blanking head 117 descend, they will also drive the descending rack 201 to descend, thereby driving the intermediate gear 204 to rotate. Then, through the pushing rack 205, the pushing plate 206 is driven to slide along the side fixing plate 202, thereby driving the pushing rod 207 to move to the left side of the pressing block 118. When the blanking head 117 presses down, at this time, the pushing rod 207 is located on the left side of the blanking head 117. When the pressing frame 106 and the blanking head 117 rise, the intermediate gear 204 is driven to rotate in the reverse direction by the descending rack 201. Then, through the pushing rack 205 and the pushing plate 206, the pushing rod 207 is driven to slide towards the discharging slope 112. The alloy steel plate blanked by the blanking head 117 is pushed onto the discharging slope 112 by the pushing rod 207.

[0039] As Figure 11 、 Figure 12 shown, the winding device includes a winding wheel 302 and a transmission wheel 303 rotatably mounted on the winding frame 301. A winding roller 306 is rotatably mounted on the winding frame 301. The end of the alloy steel strip 4 passes through the transmission wheel 303 and the winding roller 306 and is fixed on the winding wheel 302. A driven gear 307 is fixedly mounted on the winding roller 306. A driving gear 308 is rotatably mounted on the winding frame 301. A half-tooth gear 309 is fixedly mounted on the driving gear 308. The half-tooth gear 309 meshes with the driven gear 307. A horizontal transmission belt 125 is wound around the driving gear 308 and the external transmission wheel 124.

[0040] As Figure 11 、 Figure 12 shown, a belt pressing mechanism is provided on the winding frame 301. The belt pressing mechanism includes a heavy pressing rotating frame 304 rotatably mounted on the winding frame 301. A pressing wheel 305 is rotatably mounted on the heavy pressing rotating frame 304. The gravity of the heavy pressing rotating frame 304 causes the pressing wheel 305 to press the alloy steel strip 4 against the winding roller 306.

[0041] The horizontal transmission belt 125 drives the driving gear 308 and the half-tooth gear 309 to rotate. The half-tooth gear 309 drives the driven gear 307 to rotate periodically. When the toothed part of the half-tooth gear 309 contacts the driven gear 307, it drives the driven gear 307 to rotate. When the toothless part of the half-tooth gear 309 cooperates with the driven gear 307, it does not drive the driven gear 307 to rotate. The rotation of the driven gear 307 drives the winding roller 306 to rotate, thereby driving the alloy steel strip 4 to be wound onto the winding wheel 302. The heavy pressing rotating frame 304 causes the pressing wheel 305 to always press the alloy steel strip 4 against the winding roller 306. Using the winding roller 306 to drive the alloy steel strip 4 for winding can keep the winding speed of the alloy steel strip 4 constant.

[0042] The working principle of a blanking device for alloy steel plates disclosed by the present invention is as follows: The end of the alloy steel strip 4 passes through the feeding roller 113. Meanwhile, the alloy steel strip 4 is located between the front pre-punch 115, the rear pre-punch 116, the blanking head 117 and the lower pressing block 118. Subsequently, the alloy steel strip 4 passes through the discharging roller 114, the transmission wheel 303 and the winding roller 306 and is fixed on the winding wheel 302. The motor 127 rotates to drive the motor gear 128 to rotate, drives the inner transmission wheel 123 and the outer transmission wheel 124 to rotate through the inclined transmission belt 126, drives the transmission gear 308 to rotate through the horizontal transmission belt 125. At the same time, the inner transmission wheel 123 drives the heavy turntable 102 to rotate, the heavy turntable 102 rotates to drive the rotating rod 103 to rotate, thereby driving the lifting block 104 to lift along the guiding frame 105, thereby driving the connecting block 108 and the lower pressing frame 106 to lift, thereby driving the front pre-punch 115, the rear pre-punch 116 and the blanking head 117 to lift. The front pre-punch 115 and the rear pre-punch 116 perform pre-blanking on the alloy steel strip 4 below them. Finally, the alloy steel strip 4 is blanked by the blanking head 117 and the blanking cutter 122. When the lower pressing frame 106 and the blanking head 117 descend, it will also drive the descending rack 201 to descend, thereby driving the intermediate gear 204 to rotate, and thereby driving the pushing plate 206 to slide along the side fixing plate 202 through the pushing rack 205, thereby driving the pushing rod 207 to move to the left side of the lower pressing block 118. When the blanking head 117 presses down, at this time, the pushing rod 207 is located on the left side of the blanking head 117. When the lower pressing frame 106 and the blanking head 117 rise, the intermediate gear 204 is driven to rotate in the reverse direction through the descending rack 201, and thereby the pushing rod 207 is driven to slide towards the discharging slope 112 through the pushing rack 205 and the pushing plate 206. The alloy steel plate blanked by the blanking head 117 is pushed onto the discharging slope 112 by the pushing rod 207 and leaves along the discharging slope 112. The horizontal transmission belt 125 drives the transmission gear 308 and the semi-tooth gear 309 to rotate. The semi-tooth gear 309 drives the driven gear 307 to rotate periodically. When the toothed part of the semi-tooth gear 309 contacts the driven gear 307, it drives the driven gear 307 to rotate. When the toothless part of the semi-tooth gear 309 cooperates with the driven gear 307, it does not drive the driven gear 307 to rotate. The driven gear 307 rotates to drive the winding roller 306 to rotate, thereby driving the winding roller 306 to wind onto the winding wheel 302. The heavy pressing frame 304 makes the pressing wheel 305 always press the alloy steel strip 4 on the winding roller 306. Using the winding roller 306 to drive the alloy steel strip 4 to wind can keep the winding speed of the alloy steel strip 4 constant. Whenever the lower pressing frame 106 drives the front pre-punch 115, the rear pre-punch 116 and the blanking head 117 to descend, the alloy steel strip 4 does not move. When the front pre-punch 115, the rear pre-punch 116 and the blanking head 117 rise, the alloy steel strip 4 moves forward one station. The part originally located below the front pre-punch 115 moves below the rear pre-punch 116, and the part originally located below the rear pre-punch 116 moves below the blanking head 117.When the current pre-punch 115, the rear pre-punch 116 or the blanking head 117 punches down on the alloy steel strip 4, the front pre-punch 115, the rear pre-punch 116 or the blanking head 117 presses the alloy steel strip 4 onto the lower pressing block 118, and at the same time drives the lower pressing block 118 to descend. The pressing column spring 120 is compressed, and buffering is carried out through the pressing column spring 120 to prevent damage to the front pre-punch 115, the rear pre-punch 116 or the blanking head 117 and the lower pressing block 118. The exhaust hole 121 is used for exhausting and relieving pressure.

[0043] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
