Electrochemical machining is used to generate the helical lobe profiles of the stator of a progressive cavity pump or motor. A thin, elastomeric liner, of uniform thickness is bonded either to the interior of the stator, or to the exterior of the rotor. Where the elastomeric liner is to be bonded to the interior of the stator, bonding is improved by electrically etching the interior of the stator during the electrochemical machining process to produce a roughened surface.

The present invention relates to a mounting and dismounting device for an oil material roller. The mounting and dismounting device is characterized by comprising hydraulic transmission, crank transmission and fixed connection mechanisms; the hydraulic transmission mechanism comprises a double-acting cylinder (4), a piston rod (19) cooperating with the double-acting cylinder (4) to act, a cylinder tailstock (2) and a hinge pin (3); and the crank transmission mechanism comprises a hydraulic rotating arm (7), a roller adjusting shaft sleeve (12), a supporting shaft (5), a large check ring (6), an arc-shaped cover (17), a chuck (18), a bolt (10), a jackscrew (11), nuts (13) and studs (23), and besides, a structure that a connecting rod (27) is arranged at the upper part of the hydraulic rotating arm (7) to replace the roller adjusting shaft sleeve (12), the jackscrew (11), nuts (13) and studs (23) is adopted by the mechanism. The mounting and dismounting device has the characteristics of safe and stable structure, safety and accuracy in mounting and dismounting, high quality and efficiency, low cost and the like.

The invention discloses a sawing machine for forming an opening in a taper sleeve. The sawing machine comprises a rotary disc (1), a hydraulic dividing plate (2), an opening forming device (3) and a hydraulic system (4). The rotary disc (1) is rotationally mounted at the output end of the hydraulic dividing plate (2). A plurality of clamps (5) used for taper sleeve tooling are evenly distributed on the top surface of the rotary disc (1) in the edge direction of the rotary disc (1). The sawing machine has the beneficial effects that the smoothness of the outer surface of the taper sleeve is protected, taper sleeve tooling is achieved fast, the labor intensity of workers is relieved, and the opening forming efficiency is improved.

The invention discloses a system for producing a taper sleeve. The system comprises a nine-station machine tool, a groove processing machine tool and a key slot processing machine tool. The invention further discloses a machining technique for the taper sleeve. The system and technique for producing the taper sleeve have the beneficial effects that the smoothness of the outer surface of the taper sleeve is protected, the degree of automation is high, assembling of the taper sleeve is achieved quickly, the machining precision is high, the taper sleeve production efficiency is improved, the labor intensity of workers is relieved, and the taper sleeve production capacity is improved.

The invention discloses a water-saving environment-friendly car washer without damaging car paint. The water-saving environment-friendly car washer comprises a water tank and a handheld car washer, wherein the handheld car washer comprises a handheld part and a washing part; the handheld part is provided with a speed regulating device driven by a motor; a gear A in the speed regulating device drives a high-speed shaft; the high-speed shaft drives a low-speed shaft through a gear B; the low-speed shaft is a hollow shaft; the washing part comprises a rotating disk and a circular hairbrush chassis; three supporting rods are arranged on the lower surface of the hairbrush chassis, two supporting rods are 21mm in length, and the other one supporting rod is 27mm in length; an inclination angle which is 8.4 degrees is formed between the hairbrush chassis and the horizontal plane; universal wheels are arranged on the lower ends of the supporting rods. Due to the design characteristic of two short supporting rods and one long supporting rod, the inclination angle is enabled to be formed by a rotary hairbrush and the surface of a car body when the rotary hairbrush is in rotary washing, so that in-time draining of girt in the rotary hairbrush can be ensured, the damage to the car paint due to long-time friction of the girt in the rotary hairbrush during washing is avoided, and the integrality and the smooth finish of the car paint are greatly protected.

The invention discloses a hot forging and molding process for oxygen free copper materials. The hot forging and molding process is different from the traditional cold extrusion process in prior art. According to this process, a hot forging method is adopted to process the oxygen free copper materials and process parameters including a preheating temperature of moulds, a heating temperature of materials, and a lubrication oil component are ensured. The hot forging and molding process can be used to prepare precise oxygen free copper components which are smooth on surface, good in performance, and qualified in combustion. The process steps are simple to operate and applicable to industrialization promotion, the finished product rate is high, and all the parameters of products are excellent.
