Description

Technical Field

[0001] The present invention belongs to the field of molds, and particularly relates to a multi-station mold capable of rapid positioning. Background Art

[0002] With the development of industrial technology, modern mold technology has become more and more perfect. Stamping molds can stamp sheets in batches with relatively high working efficiency. If the sheets need to be stamped by multiple molds, it is necessary to push the sheets into multiple stamping molds for stamping operations, which is very labor-consuming. For example, a precision stamping mold capable of rapid positioning disclosed in Patent No. 202021205028.6 relates to the field of precision stamping molds. The precision stamping mold capable of rapid positioning includes a frame. A number of groups of support fixing feet are fixedly installed at the lower end of the frame. A fixed-end stamping mold is fixedly installed at the upper end of the frame. A number of groups of limit sliding shafts are fixedly installed at the upper end of the fixed-end stamping mold. A limit block is fixedly installed at one end of each group of limit sliding shafts away from the fixed-end stamping mold. A mobile-end stamping mold is movably installed at the upper end of the fixed-end stamping mold. In the precision stamping mold capable of rapid positioning, each group of support rotating shafts penetrate through both ends of the corresponding limit fixing block, and the distance between each group of support rollers and the corresponding limit fixing block is equal, so that the frame has a moving function and a support roller protection function, thereby improving the scope of use and service life. This device still has defects when in use. First, the molds on this device are relatively single. Only one type of groove can be stamped on the sheet each time. If grooves of multiple different sizes need to be punched on the sheet, it is necessary to place the sheet workpiece on multiple stamping molds for stamping. Second, the previous molds were relatively difficult to debug. Each time the equipment was debugged, the molds needed to be completely disassembled, and debugging or maintenance was very time-consuming and laborious. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-station mold capable of rapid positioning in view of the deficiencies of the prior art. When this device is in use, the sheet to be processed is placed on the loading platform and locked in position with the pressing plate. The loading platform and the sheet workpiece on its top advance one unit distance along the guide groove. The electric push rod pushes out the positioning strip. The other end of the positioning strip then pushes the translation module backward by a certain distance. The hydraulic press drives the mold box and the translation module to drop for stamping operations. The lengths of the six positioning strips are different. Therefore, the distances that the translation module is pushed backward are also different. Six impact grooves of different sizes can be punched on the sheet workpiece. Thus, stamping grooves of different sizes can be stamped on the same stamping mold to solve the problems mentioned in the background art.

[0004] To solve the above problems, the present invention provides the following technical solution: A multi-station mold capable of rapid positioning, including a base plate and a sliding table. A zigzag pipe is fixedly arranged at the top end of the base plate. A positioning turntable is rotatably arranged at the end of the zigzag pipe. The positioning turntable is connected to a torsion positioning component. Six pipe orifices are arranged on the side wall of the positioning turntable. A pipe sleeve is arranged in each pipe orifice. A positioning bar is slidably inserted inside the pipe sleeve. A resilient reset mechanism is arranged between the positioning bar and the pipe sleeve. A length adjustment mechanism is arranged in the middle of the positioning bar. Contact balls are arranged at both ends of the positioning bar. An electric push rod is fixedly arranged in front of the base plate. A contact piece is arranged on the output rod of the electric push rod. The axis of the contact piece is aligned with the positioning bar at the highest position. A loading platform is slidably installed at the top end of the sliding table. A guide groove is arranged at the top end of the sliding table. A slider inserted inside the guide groove is arranged at the bottom end of the loading platform. The loading platform is connected to a linear propulsion component. A pressure bridge is arranged at the top end of the loading platform. A compaction component is arranged on the pressure bridge. Loading frames are arranged at both ends of the loading platform. A sheet workpiece passes through the middle of the loading frames. An arch bridge is arranged at the top end of the sliding table. A hydraulic press is arranged at the top end of the arch bridge. A mold box is arranged on the output rod of the hydraulic press. A translation module is slidably installed inside the mold box. The front side wall of the translation module is connected to the side wall of the mold box through an expansion spring. A limiting block is arranged on the rear side wall of the translation module. Six linearly arrayed reserved impact grooves are arranged on the loading platform. The translation module is vertically aligned with the reserved impact grooves and horizontally aligned with the positioning bar at the highest position. A cutting block is detachably installed inside the reserved impact grooves.

[0005] Further, the torsion positioning component includes a stepping motor at the top end of the base plate. A driving wheel disc is installed at the output end of the stepping motor. A central shaft is arranged at the axis of the positioning turntable. A driven wheel disc is arranged at the end of the central shaft. The driving wheel disc and the driven wheel disc are connected through a positioning belt.

[0006] Further, the length adjustment mechanism includes an interruption link in the middle of the positioning bar. The positioning bar is additionally installed inside the interruption link. The positioning bar and the lengthening square rod are connected through a pin rod assembly.

[0007] Further, the pin rod assembly includes blocks at both ends of the lengthening square rod. A rectangular groove matching the blocks is arranged in the middle of the positioning bar. The blocks are inserted into the rectangular groove. Insertion holes are arranged on the side walls of the blocks and the positioning bar. The insertion holes are fixedly connected through a pin.

[0008] Further, the linear propulsion component includes shaft seats at both ends of the sliding table. A carrying rod is rotatably arranged on one side of the shaft seat. The carrying rods are connected through a carrying belt. And the carrying rods are installed at the output end of a servo motor. The bottom surface of the loading platform is connected to the carrying belt.

[0009] Further, the compaction component includes two nuts at the top of the pressure bridge. A threaded rod is rotatably arranged inside the nuts. A torsion handle is arranged at the top of the threaded rod. A bearing is arranged at the bottom of the threaded rod. The inner ring of the bearing is fixedly connected to the threaded rod. A pressing plate is fixedly arranged on the outer ring of the bearing. The pressing plate presses on the sheet workpiece.

[0010] Further, the translation module and the cutting block are made of high-speed steel. The width of the translation module is two millimeters greater than the width of the reserved impact groove. The translation module and the reserved impact groove are centered and aligned in the vertical direction.

[0011] Further, a steel rod is arranged at the end of the positioning bar. External threads are arranged on the outer side of the steel rod. An internal threaded hole matching the external threads is arranged on the side wall of the abutting ball. The surface of the abutting ball is polished.

[0012] Further, the elastic reset mechanism includes two pulling rubber bands outside the positioning bar. The outer side wall of the positioning bar is fixedly connected to the side wall of the sleeve through the pulling rubber bands. And machine oil is applied between the sleeve and the positioning bar.

[0013] Further, a rubber pad is arranged on the bottom surface of the pressing plate. Rubber blocks are arranged on the rubber pad. Grooves matching the rubber blocks are arranged on the bottom surface of the pressing plate.

[0014] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects: First, when the device is in use, the sheet to be processed is placed on the loading platform and locked in position with the pressing plate. For every unit distance that the loading platform and the sheet workpiece on its top advance along the guide groove, the electric push rod pushes out the positioning bar. The other end of the positioning bar then pushes the translation module backward by a certain distance. The hydraulic press drives the die box and the translation module to drop for stamping operations. The lengths of the six positioning bars are different. Consequently, the distances that the translation module is pushed backward are also different. Six impact grooves of different sizes can be punched on the sheet workpiece. Thus, different-sized stamping grooves can be punched on the same stamping die.

[0015] Second, the pin inside the insertion hole on the positioning bar can be pulled out. Thus, the positioning bar and the lengthening square rod in the middle of it can be separated. The staff can replace the lengthening square rods of different lengths according to the stamping requirements. The cutting blocks inside the reserved impact grooves are also correspondingly replaced with different lengths, achieving the effect of portable equipment debugging.

[0030] In a further embodiment of the present invention, as Figures 1-4 shown, the length adjustment mechanism includes an interruption link in the middle of the positioning strip 402. The positioning strip 402 is installed inside the interruption link, and the positioning strip 402 and the lengthened square rod 404 are connected by a pin rod assembly.

[0031] In this embodiment, the staff replaces the lengthened square rods 404 with different lengths according to the stamping requirements, and the cutting blocks 704 inside the reserved impact grooves 801 also correspondingly change to different lengths, achieving the effect of portable debugging equipment.

[0034] In a further embodiment of the present invention, as Figures 1-5 shown, the linear propulsion assembly includes shaft seats 9 at both ends of the sliding table 2. A carrying rod 901 is rotatably provided on one side of the shaft seat 9. The carrying rods 901 are connected by a carrying belt 902, and the carrying rod 901 is installed at the output end of the servo motor 903. The bottom surface of the load platform 8 is connected to the carrying belt 902.

[0035] In this embodiment, the servo motor 903 drives the carrying belt 902 to operate through the carrying rod 901. The load platform 8 slides synchronously with the carrying belt 902, and the distance advanced by the load platform 8 each time is the distance between two reserved impact grooves 801.

[0036] In a further embodiment of the present invention, as Figures 1-7 shown, the compaction assembly includes two nuts at the top of the pressure bridge 803. A threaded rod 804 is rotatably arranged inside the nuts. A torsion handle is provided at the top of the threaded rod 804. A bearing 806 is provided at the bottom of the threaded rod 804. The inner ring of the bearing 806 is fixedly connected to the threaded rod 804. A pressing plate 805 is fixedly arranged on the outer ring of the bearing 806. The pressing plate 805 presses on the plate workpiece.

[0037] In this embodiment, after the plate workpiece is placed on the loading platform 8, the worker manually rotates the threaded rod 804. The threaded rod 804 advances downward inside the nuts until the pressing plate 805 presses on the plate workpiece and locks its position.

[0038] In a further embodiment of the present invention, as Figures 1-7 shown, the translation module 701 and the cutting block 704 are made of high-speed steel. The width of the translation module 701 is two millimeters greater than the width of the reserved impact groove 801. The translation module 701 and the reserved impact groove 801 are vertically centered and aligned.

[0039] In this embodiment, the translation module 701 drops down and passes through the reserved impact groove 801. Then, a rectangular slot will be punched out of the plate workpiece.

[0040] In a further embodiment of the present invention, as Figures 1-5 shown, a steel rod is provided at the end of the positioning strip 402. External threads are provided on the outer side of the steel rod. An internal threaded hole matching the external threads is provided on the side wall of the abutting ball 407. The surface of the abutting ball 407 is polished.

[0041] In this embodiment, the abutting ball 407 can be detached from the positioning strip 402. The abutting ball 407 can be taken down regularly to check whether its contour is deformed.

[0042] In a further embodiment of the present invention, as Figures 1-3 shown, the elastic reset mechanism includes two pulling rubber bands 403 outside the positioning strip 402. The outer side wall of the positioning strip 402 is fixedly connected to the side wall of the pipe sleeve 401 through the pulling rubber bands 403. And machine oil is applied between the pipe sleeve 401 and the positioning strip 402.

[0043] In this embodiment, when the abutting piece of the electric push rod 101 disengages from the positioning strip 402, the positioning strip 402 is pulled back to its original position through the pulling rubber bands 403.

[0044] In a further embodiment of the present invention, as Figures 1-7As shown, a rubber pad is provided on the bottom surface of the pressing plate 805, and rubber blocks are provided on the rubber pad. Grooves matching the rubber blocks are provided on the bottom surface of the pressing plate 805.

[0045] In this embodiment, the rubber bands on the bottom surface of the pressing plate 805 increase the degree of fit with the sheet workpiece, avoiding the slipping of the sheet workpiece.

[0046] Working principle: Place the sheet to be processed on the loading platform 8 and lock it. As the loading platform 8 and the sheet workpiece on its top advance one unit distance along the guide groove 201, the electric push rod 101 pushes out the positioning bar 402. The other end of the positioning bar 402 then pushes the translation module 701 backward by a certain distance. The hydraulic press 6 drives the die box 701 and the translation module 702 to drop for stamping operations. The lengths of the six positioning bars 402 are different, so the distances that the translation module 701 is pushed backward are also different. Six impact grooves of different sizes can be punched out on the sheet workpiece. Compared with the existing stamping dies, only one type of stamping groove can be stamped by a previous stamping die, while the present invention can stamp stamping grooves of different sizes on the same stamping die. The stepping motor 10 drives the positioning belt 1004 to rotate through the driving wheel disc 1001. The positioning belt 1004 drives the central shaft 1003 and the positioning turntable 4 to rotate through the driven wheel disc 1002. The six positioning bars 402 on the positioning turntable 4 can take turns to reach the top ejection station. The staff can replace the extension square rods 404 of different lengths according to the stamping requirements, and the cutting blocks 704 inside the reserved impact groove 801 also correspondingly change to different lengths, achieving the effect of portable debugging equipment. The pins inside the insertion holes 406 on the positioning bar 402 can be pulled out, so that the positioning bar 402 and the extension square rod 404 in the middle can be separated. Replace the positioning bar 402 of different lengths and then insert the pins back. The servo motor 903 drives the conveying belt 902 to rotate through the conveying rod 901. The loading platform 8 slides synchronously with the conveying belt 902. The distance advanced by the loading platform 8 each time is the distance between two reserved impact grooves 801. After the sheet workpiece is placed on the loading platform 8, the staff manually rotates the threaded rod 804, and the threaded rod 804 advances downward inside the nut until the pressing plate 805 presses the sheet workpiece and locks the position. The translation module 701 drops and passes through the reserved impact groove 801, and then a rectangular slot will be punched out from the sheet workpiece. The abutting ball 407 can be disassembled relative to the positioning bar 402, and the abutting ball 407 can be taken down regularly to detect whether the contour is deformed. When the abutting piece of the electric push rod 101 disengages from the positioning bar 402, the positioning bar 402 is pulled back to its original position by the pulling rubber band 403. The rubber bands on the bottom surface of the pressing plate 805 increase the degree of fit with the sheet workpiece, avoiding the slipping of the sheet workpiece.
