A transfer device for a hot bending apparatus

Abstract

This utility model discloses a transfer device for hot bending equipment, belonging to the technical field of hot bending equipment. It includes a base with multiple rectangular grooves linearly arrayed on both sides of the top of the base, and a handle unit on one side of the top of the base. A connecting sleeve is located at the center of the handle unit. In this utility model, when the device needs to be stopped, the operator's finger automatically disengages from the telescopic trigger unit. At this time, a torsion spring drives the circular shaft and the second lead screw to rotate in the opposite direction, causing the trapezoidal block to move upwards and, through the conical block, to drive the connecting rod and friction block towards the wear-resistant ring. The friction block contacts the wear-resistant ring, increasing the friction on the moving wheel, thereby limiting the rotation of the moving wheel and ensuring the stability of the device when stopped. This device, with its design of moving when gripped and stopping when released, is suitable for short-distance, high-frequency workstation switching scenarios in hot bending processes, significantly improving the efficiency of high-frequency transfer operations.

[0002] Hot bending equipment is an industrial processing equipment that softens materials by heating them and then uses molds or external forces to cool and shape them in a specific shape, thereby obtaining a permanent bent shape. In the hot bending process, in order to ensure the connection between upstream and downstream processes, as well as to ensure production efficiency and product quality, it is necessary to transfer and process the materials through a device.

It includes a support plate, a front moving wheel and a rear moving wheel. Several support seats are fixedly installed at the bottom of the support plate. A drive mechanism is provided between the front moving wheel, the rear moving wheel and the support seats. A storage rack is fixedly installed at the top of the support plate. Several limiting plates are fixedly installed on the inner wall of the storage rack. A storage frame and a reset assembly are provided between the limiting plates. The drive mechanism includes a motor and a pressing rod. The motor drives the welded elbow inside the storage frame to move through the pressing rod and the reset assembly, thereby reducing the blind zone of air cooling of the welded elbow.

The extension component 6 is located inside the base 1 and is used to adjust the lateral position of the base 1 for wider applicability. The brake assembly 7 includes four friction blocks 707 symmetrically arranged in pairs inside the base 1. The friction blocks 707 and the wear ring are on the same horizontal plane, and are used to adjust the working position between the friction blocks 707 and the wear ring by triggering the connecting sleeve 5. Brake assembly 7 also includes: A circular shaft 701 is rotatably connected to the bottom inside the base 1; A torsion spring 709 is disposed inside the base 1 and is sleeved on the outer circumference of the round shaft 701; The spool 708 is located inside the base 1 and is fixedly connected to the outer circumference of the round shaft 701. The spool 708 is located above the torsion spring 709. A cord 710 is sleeved on the outer periphery of the reel 708, and the other end of the cord 710 extends to the outside of the base 1 and is provided with a telescopic trigger unit. The telescopic trigger unit is located inside the connecting sleeve 5 on the side opposite to the base 1. The telescopic trigger unit consists of a spring, a sliding plate and a guide rod. One end of the guide rod extends to the outside of the connecting sleeve 5, and the other end of the guide rod is fixedly connected to the sliding plate that is slidably connected inside the connecting sleeve 5. The other side of the sliding plate is fixedly connected to the spring that is fixedly connected to the inner wall of the connecting sleeve 5. The end of the cord 710 away from the reel 708 is fixedly connected to the side of the sliding plate away from the spring. The second lead screw 702 is fixed to the top of the round shaft 701; Trapezoidal block 703 is slidably connected to the inner bottom side of base 1, and trapezoidal block 703 is connected to the outer periphery of second lead screw 702 through lead screw sleeve on the inner bottom side. Four conical blocks 704 are symmetrically arranged in pairs on the bottom side inside the base 1, and the inclined surfaces of the conical blocks 704 are in contact with the inclined surfaces of the trapezoidal blocks 703.

[0020] Detailed Implementation: The workpiece to be heat-bent is placed directly on the top of the base 1 or placed on the support mold, and the support mold and workpiece are placed together on the top of the base 1. When the operator manually operates the connecting sleeve 5 to move the base 1 and the workpiece for transfer processing in the heat bending process, the operator's finger is connected to the telescopic trigger unit. That is, the finger will drive the sliding plate through the guide rod to squeeze the spring, causing the sliding plate to drive the wheel 708, the round shaft 701 and the second lead screw 702 to rotate through the rope 710. The second lead screw 702 drives the trapezoidal block 703 to move downward, and the force of the spring 706 will drive the conical block 704, the connecting rod 705 and the friction block 707 to move away from the wear ring. When it is necessary to stop the device, the operator's finger will automatically disengage from the telescopic trigger unit. At this time, the torsion spring 709 drives the round shaft 708 to rotate. 01 and the second lead screw 702 rotate in opposite directions, causing the trapezoidal block 703 to move upward and squeeze the conical block 704. This causes the conical block 704 to drive the connecting rod 705 and the friction block 707 to move towards the wear-resistant ring. The friction block 707 contacts the wear-resistant ring and increases the friction on the moving wheel 4, thereby limiting the rotation of the moving wheel 4 and ensuring the stopping stability of the device. This device is designed to move when held by the fingers and stop when released, making it suitable for short-distance, high-frequency workstation switching scenarios in hot bending processes, which greatly improves the efficiency of high-frequency transfer. The telescopic trigger unit can be selected according to actual needs. The telescopic trigger unit can be used to stretch the rope 710 to drive the wheel 708 to rotate. The friction block 707 can be set to U-shape according to actual needs. The energy storage system, control system and power system involved in this device are all known and disclosed technologies known to those skilled in the art, so this application does not elaborate on them.

[0022] Detailed implementation: Start the drive motor 608, which drives the fixed shaft and the second gear 607 to rotate. This causes the first gear 606 to drive the rotating shaft 601 and the first lead screw 602 to rotate. This causes the rectangular lead screw sleeve 603 to drive the L-shaped slide plate 604 and the extension plate 605 to move in opposite directions. This expands and adjusts the horizontal platform at the top of the base 1, making it suitable for workpiece transfer needs of different widths.
