Description

Technical Field

[0001] The present invention relates to the field of metal stamping, and in particular to a motorhome die for stamping parts. Background Art

[0002] The RV stamping process refers to a processing method that uses pressure to plastically deform metal sheets and ultimately form various parts required for RVs.

[0003] In the process of installing various parts, metal connectors are often used to connect various parts. Therefore, the metal connectors need to be punched into the required angles.

[0017] 3. Under the action of the transverse spring, the two positioning frames and the two positioning rods will move towards each other, and the two positioning rods will contact the end of the metal connector. Since the end of the metal connector is set as an arc surface, the two positioning rods will push the metal connector to move towards the hydraulic rod, and then further position the position of the metal connector, thereby performing a secondary correction on the metal connector, making the position of the metal connector more accurate, thereby further improving the efficiency and accuracy of the metal connector after stamping.

Two driving racks 84 are installed on the side where the two sliding plates 81 are close to each other. A driving gear 85 is rotatably installed on both sides of the middle part of the cylinder 2 through bearings. The two driving racks 84 located on different sliding plates 81 are located on both sides of the driving gear 85 on the same side, and the driving rack 84 is engaged with the driving gear 85.

[0039] The correction mechanism includes a fixed plate 91, a correction rod 92, a correction protrusion 921, a column gear 93, a cross rack 94, a long roller 95 and a groove frame 96. Two fixed plates 91 are installed in the cylinder 2. The two fixed plates 91 are each provided with a correction rod 92 on the side close to each other through a bearing rotation. The two correction rods 92 are each provided with two correction protrusions 921 for correcting the metal connecting piece 51 on the side close to each other. The metal connecting piece 51 is located between the four correction protrusions 921. A column gear 93 is installed on the two correction rods 92. A cross rack 94 is slidingly provided on the two fixed frames 3. The cross rack 94 will slide along the fixed frame 3. The cross rack 94 on the same side is meshed with the column gear 93 on the same side. A long roller 95 is installed on the two cross racks 94. Two groove frames 96 are installed on the side of the two sliding plates 81 close to each other.

[0040] The slot frame 96 has a guide groove formed thereon. The guide groove of the slot frame 96 consists of an oblique groove and a straight groove. Both sides of the long roller 95 on the same side are respectively located in the oblique grooves on the two slot frames 96 on the same side.

[0041] The two correction protrusions 921 on the correction rod 92 are arranged in a straight line.

[0042] The pressing mechanism includes a pressing frame 101, a push rod 1011, a ball 102, a return spring 103, a driving frame 104, a ring 105, a semi-arc protrusion 106 and a semi-arc protrusion 2 107, wherein a pressing frame 101 for pressing the metal connecting piece 51 is slidably provided on one of the hollow fixed tubes 4, and two push rods 1011 are provided on the pressing frame 101. The lower part of the pressing frame 101 passes through the upper part of the placement frame 5, and a number of balls 102 are provided on the lower part of the pressing frame 101. A return spring 103 is connected between the pressing frame 101 and the placement frame 5, and a driving frame 104 is installed on one of the correction rods 92. A ring 105 is installed on the lower part of the driving frame 104, and two semi-arc protrusions 106 are installed on the ring 105. A semi-arc protrusion 2 107 is respectively installed on the two semi-arc protrusions 106, and the two push rods 1011 are in contact with the bottom of the ring 105.

[0043] One side of the semi-arc protrusion 106 and the semi-arc protrusion 107 is configured as an inclined surface.

[0044] First, the operator places the metal connector 51 into the placement rack 5 through the feed port 21, and then the operator controls the telescopic rods of the two hydraulic rods 6 to extend, and the telescopic rods of the two hydraulic rods 6 drive the punching block 7 to move downward, and the upper punching block 7 drives the connecting frame 83 to move downward, and the connecting frame 83 drives the upper sliding plate 81, the upper opening and closing plate 82 and the two upper driving racks 84 to move downward, and the upper two driving racks 84 drive the two driving gears 85 to rotate, and the two driving gears 85 drive the lower two driving racks 84 to move upward, and the lower two driving racks 84 drive the lower sliding plate 81 and the lower opening and closing plate 82 to move upward, and the upper opening and closing plate 82 and the lower opening and closing plate 82 are rotated. When the two sliding plates 81 move toward each other and contact each other, they can block the feed port 21, and then the feed port 21 can be closed during the stamping operation, thereby avoiding the occurrence of safety hazards; when the two sliding plates 81 move toward each other, they drive the four slot frames 96 to move toward each other. Under the action of the inclined grooves on the slot frames 96, the two long rollers 95 and the two transverse racks 94 will move toward the direction of the hydraulic rod 6. After the two long rollers 95 move to the straight grooves on the slot frames 96, the two long rollers 95 and the two transverse racks 94 no longer move. When the two transverse racks 94 move toward the direction of the hydraulic rod 6, they drive the two column gears 93 to rotate. The rotation of the two column gears 93 drives the two correction rods 9 2 and the four correction protrusions 921 rotate, the two correction rods 92 and the four correction rotations will contact the two sides of the metal connector 51 and push the metal connector 51 to swing, thereby performing a preliminary correction on the position of the metal connector 51; after the metal connector 51 is initially corrected, the position of the metal connector 51 is made more accurate, thereby improving the efficiency and accuracy of the metal connector 51 after stamping, and when the correction rod 92 rotates, it drives the driving frame 104, the ring 105, the semi-arc protrusion 1 106 and the semi-arc protrusion 2 107 to rotate, and the inclined surfaces on the semi-arc protrusion 106 and the semi-arc protrusion 2 107 contact the push rod 1011 in turn, and after the semi-arc protrusion 106 contacts the push rod 1011, the push rod 10 11. The lower pressing frame 101 and the ball 102 move downward for a distance. After the semi-arc protrusion 107 contacts the push rod 1011, the ball 102 moves downward and presses against the metal connector 51. The return spring 103 is compressed accordingly, thereby pressing the metal connector 51. After the metal connector 51 is pressed and corrected, the punching block 7 continues to move downward. After the punching block 7 contacts one side of the metal connector 51, since the side of the lower part of the punching block 7 close to the placement frame 5 is inclined at 45 degrees, the metal connector 51 will first bend to 45 degrees along the inclined surface of the lower part of the punching block 7. When the vertical surface of the punching block 7 contacts the metal connector 51, the metal connector 51 will be punched and bent to 90 degrees.The inclined surfaces on the semi-arc protrusion 106 and the semi-arc protrusion 2 107 contact the push rod 1011 in turn, thereby driving the push rod 1011, the lower pressing frame 101 and the ball 102 to move downward and press against the metal connector 51. After the metal connector 51 is pressed and corrected, the punching block 7 continues to move downward to punch the metal connector 51, thereby further improving the efficiency and accuracy of the metal connector 51 after punching; after the metal connector 51 is punched, the operator controls the telescopic rods of the two hydraulic rods 6 to shorten, and the telescopic rods of the two hydraulic rods 6 drive the punching block 7 to move upward, and the upper punching block 7 drives the connecting frame 83 moves upward, the connecting frame 83 drives the upper sliding plate 81, the upper opening and closing plate 82 and the two upper driving racks 84 to move upward, the upper two driving racks 84 drive the two driving gears 85 to rotate in the opposite direction, the two driving gears 85 drive the two lower driving racks 84 to move downward, the lower two driving racks 84 drive the lower sliding plate 81 and the lower opening and closing plate 82 to move downward, the upper opening and closing plate 82 and the lower opening and closing plate 82 move in the direction away from each other to open the feed port 21; when the two sliding plates 81 move in the direction away from each other, they drive the four slot frames 96 to move toward each other. When the two cross racks 94 move in the direction away from the hydraulic rod 6, the two long rollers 95 and the two cross racks 94 will move in the direction away from the hydraulic rod 6. When the two cross racks 94 move in the direction away from the hydraulic rod 6, they drive the two column gears 93 to rotate in the opposite direction. The two column gears 93 rotate in the opposite direction and drive the two correction rods 92 and the four correction protrusions 921 to rotate in the opposite direction. The two correction rods 92 and the four correction reverse rotations will separate from the two sides of the metal connector 51. When the correction rod 92 rotates in the opposite direction, it drives the drive frame 104, the ring 105, the semi-arc protrusion 1 106 and the semi-arc protrusion 2 107 to rotate in the opposite direction. The semi-arc protrusion 1 After 106 and the second semi-arc protrusion 107 rotate in the opposite direction, they separate from the push rod 1011. Under the action of the return spring 103, the push rod 1011, the lower pressing frame 101, and the ball 102 move upward to reset. After the ball 102 moves upward, it separates from the metal connector 51. The operator then picks up a new metal connector 51 and places it into the placement frame 5. The new metal connector 51 pushes the stamped metal connector 51 to move, and the stamped metal connector 51 separates from the placement frame 5 and falls. This process is repeated to continuously press, correct, and stamp the metal connector 51.

[0045] Example 2: Based on Example 1, Figure 14-16As shown, it also includes a positioning mechanism, which is arranged on the placement rack 5 and the lower pressure rack 101. The positioning mechanism is used to position the metal connector 51. The positioning mechanism includes a mounting box 111, a positioning rack 112, a positioning rod 1121, a transverse spring 113, a lower rack 114 and a ladder rack 115. A mounting box 111 is installed on the side of the placement rack 5 close to the feed port 21. Two positioning racks 112 for positioning the metal connector 51 are slidably provided on the mounting box 111. The two positioning racks 112 are divided into two parts on the side close to each other. There are two convex ends, and the upper part of the two positioning frames 112 is provided with a positioning rod 1121. The two positioning rods 1121 slide through the two sides of the placement frame 5 respectively. A transverse spring 113 is provided between the two positioning frames 112 and the two sides of the placement frame 5. A lower frame 114 is slidably provided on the other hollow fixed tube 4. The upper part of the lower frame 114 is fixedly connected to the lower pressure frame 101. The lower part of the lower frame 114 passes through the installation box 111. A ladder frame 115 is installed on the lower part of the lower frame 114, and the ladder frame 115 is located in the installation box 111.

[0046] The ladder frame 115 is provided with four inclined surfaces, and the four inclined surfaces on the ladder frame 115 are in contact with the four protruding ends of the positioning frame 112 respectively.

[0047] Initially, the transverse spring 113 is in a stretched state. After the semi-arc protrusion 106 contacts the push rod 1011, the push rod 1011, the lower pressure frame 101 and the ball 102 will move downward for a distance. At this time, the ball 102 will not contact the metal connector 51. The lower pressure frame 101 will drive the lower frame 114 and the ladder frame 115 to move downward. The four inclined surfaces on the ladder frame 115 move downward and gradually separate from the four convex ends on the positioning frame 112. Under the action of the transverse spring 113, the two positioning frames 112 and the two positioning rods 1121 will move towards each other. The two positioning rods 1121 will contact the end of the metal connector 51. Since the end of the metal connector 51 is an arc surface, the two positioning rods 1121 will push the metal connector 51 to move closer to the hydraulic rod 6, and then further position the position of the metal connector 51, thereby performing a secondary correction on the metal connector 51, making the position of the metal connector 51 more accurate, thereby further improving the efficiency and accuracy of the metal connector 51 after stamping; when the lower pressing frame 101 moves upward, it drives the lower frame 114 and the ladder frame 115 to move upward, and the four inclined surfaces on the ladder frame 115 move upward and gradually contact the four protruding ends on the positioning frame 112, the two positioning frames 112 and the two positioning rods 1121 will move away from each other, and the cross spring 113 will be stretched accordingly, and the two positioning rods 1121 will be separated from the end of the metal connector 51.
