The invention provides automatic assembling equipment for a blower wheel, and belongs to the technical field of blower wheel production equipment. The technical problems that after existing assemblingequipment is assembled, the stability of connection between blades and an upper disc or an upper disc is poor, and the assembling speed is low are solved. The automatic assembling equipment for the blower wheel comprises a bottom plate and a pressing head support, a rotary disc and a rotary disc driving piece are arranged on the bottom plate, an upper pressing head and an upper pressing head driving piece are arranged on the pressing head support, a lower pressing head is arranged between the rotary disc and the bottom plate, a lower pressing head driving piece is arranged on the lower side of the bottom plate, a through hole matched with the lower pressing head is formed in the rotary disc, and the upper pressing head and the lower pressing head can enable the fixed ends on the blades tobe bent in a positive and negative staggered mode. According to the automatic assembling equipment for the blower wheel, by arranging the upper pressing head and the lower pressing head, the fixed ends on the upper side and the lower side of the blower wheel are bent at the same time, and the bending speed is higher; and furthermore, the upper pressing head and the lower pressing head can enablethe fixed ends on the blades to be bent in a positive and negative staggered mode, and the connection stability is better.

An improved metal panel bending device of the invention comprises a rack; a frame is arranged above the rack, a bending groove is arranged in the upper part of the rack, the frame is provided with a hydraulic device corresponding to the bending groove, a pressing frame is arranged on the lower part of the hydraulic device, the bottom of the pressing frame is provided with a pressing bulge matched with the bending groove, the hydraulic device comprises a middle hydraulic rod and jacks on both sides, the lower part of the hydraulic rod is fixedly connected to the pressing frame, and the jacks are located between the frame and the pressing frame. The improved metal panel bending device is high in bending speed, good in bending quality and timesaving and laborsaving, and labor intensity is reduced.

The invention relates to a bending device, in particular to an efficient steel pipe bending device. According to the technical problems to be solved, the efficient steel pipe bending device provided by the invention is high in bending speed, good in bending effect and easy to operate. By means of the efficient steel pipe bending device provided by the invention, the technical problems can be solved. The efficient steel pipe bending device provided by the invention comprises a bottom plate, a cylinder I, an electric wheel, a pull wire, a sliding rail, sliding blocks, a driven wheel, a collection box, a right frame, a top plate, an electric push rod I, a material box, a support plate, a support, a pressing wheel, a supporting block, a fixed plate I, a cylinder III, a cylinder II, a fixed plate II, a clamping device, a fixed plate III, baffles, electric push rods II, clamping rings and a push plate. The cylinder I is arranged on the left side of the top of the bottom plate. The supporting block is hinged to the top end of the cylinder I. The electric wheel, the sliding rail and the driven wheel are arranged inside the bottom plate sequentially from left to right. The sliding blocks are arranged at the top of the sliding rail symmetrically. Through the efficient steel pipe bending device, the effects of the high bending speed, the good bending effect and easy operation are achieved.

The invention relates to bending equipment, in particular to plastic plate bending equipment for rubber and plastics. The plastic plate bending equipment for rubber and plastics saves time and labor,is high in bending speed and does not need manual bending, and plastic plates are not prone to falling off to be damaged. In order to achieve the technical effects, the plastic plate bending equipmentfor rubber and plastics comprises a top plate and the like; and supporting legs are installed on the left side face and the right side face of the top plate symmetrically, a transverse plate is installed between the lower portions of the inner sides of the supporting legs on the left side and the right side, a base is installed on the right side of the top of the transverse plate, a bending device is arranged on the right side of the bottom of the top plate, a bending component of the bending device is located above the base, and a pressing device is arranged on the right side of the bottom of the top plate. The plastic plates can be pressed and then bent by means of the pressing device and prevented from falling off to be damaged, and the effects that time and labor are saved, the bending speed is high, manual bending is not needed, and the plastic plates are not prone to falling off to be damaged.
