The brace is matched with a manipulator for taking workpieces, and has the advantages of saving production time, improving production efficiency, ensuring workpiece quality, precisely controlling yield, improving productivity, reducing production cost and worker labor intensity and the like.

The invention relates to a finishing mould with a top pressurizing device. The finishing mould comprises a finishing mould body and the top pressurizing device, wherein the finishing mould body comprises a lower mould board, a guide post, an upper mould board, a lower mould holder, a finishing concave mould, a convex mould, a convex mould sleeve, an upper mould guide upper board, an upper mould guide post and an upper mould guide bottom plate; the top pressurizing device comprises a hydraulic mechanism and a workpiece sleeve head; the hydraulic mechanism comprises a hydraulic cylinder and a piston rod; the piston rod and the workpiece sleeve head are connected by virtue of a shaft coupler; and the hydraulic mechanism is connected to the upper mould guide upper board by virtue of a bolt. In order to solve the solve the problem that the top of a workpiece inner cavity possibly has upward bulges for rod components produced by a conventional cold finishing mould, the invention designs a novel finishing mould; meanwhile, the top pressurizing device is additionally arranged for applying pressure to the top of a workpiece, so that a stress state of the workpiece is changed, and therefore, the top defect is eliminated.

The invention provides an intra-mode automatic screw inserting machine. A vibration plate (1) is linked with a displacement step mechanism (3) through a guide groove (2); a screw is fed to the displacement step mechanism (3) along the guide groove (2); the displacement step mechanism (3) transfers the screw to a screw inserting mechanism (4); the screw inserting mechanism (4) is placed on a rotation plate (5) through the screw; a cutter (6) rotates the rotation board (5) for 180 degrees; the rotation board (5) places the screw in a launching device (7); a mechanical arm takes away the launching device (7) provided with the screw, and places the launching device (7) in a mould; and the launching device (7) ejects and launches the screw into a positioning hole inside the mould. The intra-mode automatic screw inserting machine has the advantages that the long-term problem of automatic production as the intra-mode screw can not be nested can be solved; the production efficiency is improved; the labor investment is reduced; the labor intensity is alleviated; the intra-mode automatic screw inserting machine has a simple structure, and is not influenced by human factors; and the production period and the quality factor are stable.

The invention discloses a variable-angle variable-space discharging machine which comprises a workbench, wherein a jig plate and plastic adsorbing plates are correspondingly arranged on two sides of the front end of the workbench; the jig plate is loaded with a plurality of lines of products; the same lines of fixing slots are arranged on the plastic adsorbing plates; the angles of the products are different from those of the fixing slots; the space between adjacent products is different from the space between adjacent fixing slots; a manipulator is arranged in the center of the rear end of the workbench; a sucking part is fixed at the clamping head end of the manipulator and driven by the manipulator to freely move between the jig plate and the plastic adsorbing plates; adsorbing parts are used for adsorbing the products; through a space adjustment assembly, the space between adjacent products can be changed; through an angle adjustment assembly, the products can be rotated by certainangles; and through the adsorbing parts, the products can be placed to the fixing slots. The variable-angle variable-space discharging machine disclosed by the invention has the effects that the products can be transferred in an automated variable-angle variable-space manner; the transfer accuracy is high; and the yield is high.

The invention relates to an error prevention system for the assembly line of a clutch assembly, which prevents the front and back sides of the shell from being wrong by detecting the length of the shell feet on the shell tray when the shell is on the line; The internal and external diameter control and the diameter control of the manipulator grabbing parts prevent 1-2-3-4 gears and low gears, reverse gears, pistons, springs and ribs from mixing, and also provide a clutch assembly assembly line Error proofing method. The error prevention system and method of the present invention can ensure that mixed parts cannot be put on the line, completely eliminate wrong assembly from the source, and meet product performance requirements and output requirements.

The invention provides a novel method for annually planting white fungus in a factory. The method comprises the following steps of A, preparing fungus strains; B, preparing and bagging materials, wherein the formula of a compost comprises 15 percent of bagasse, 45 percent of cyclobalanopsis fine sawdust, 25 percent of cyclobalanopsis coarse sawdust, 14 percent of wheat bran and 1 percent of gypsum; C, performing sterilization and inoculation; D, culturing in an air-conditioning breeding warehouse, i.e. moving fungus bags into the air-conditioning breeding warehouse, and at the ninth day, moving the fungus bags into a white fungus-generating air-conditioning breeding warehouse until the fungus is cultured at the fifteenth day; E, managing during a white fungus generating period, i.e. expanding holes of the fungus bags to keep moisture, using a humidifying machine to control the whole humidity of a room to be 80 to 95 percent, and at the 35th to 37th day, harvesting and packaging the white fungus. The step of the method is innovated at home for the first time; due to the fact that an factory variety and control facilities are selected, and the most beneficial production conditions are provided according to biological characteristics in each growing stage of the white fungus, the aims of guaranteeing the yield and the quality of the white fungus and shortening the period are fulfilled, and the white fungus can be continuously produced.

The invention relates to a synthetic method of polyester resin. The synthetic method comprises esterification reaction and condensation polymerization, wherein the esterification reaction is carried out in a first level reaction kettle while the condensation polymerization is carried out in a second level reaction kettle. According to the synthetic method, by carrying out synthesis in the two reaction kettles, the production efficiency is improved and the energy consumption is reduced. The stability of the product and the operational performance of the product in the later stage are greatly enhanced due to reasonable temperature rise, pressurization and vacuum gradient.
