The invention discloses a temperature control precision improving device of a forging mechanical press. The device comprises a crankshaft bearing bush and eccentric body bush temperature control device, and further comprises a sliding block guide rail temperature control device and a ball head temperature control device; the sliding block guide rail temperature control device comprises temperaturecontrol channels arranged at the front left side, the front right side, the rear left side and the rear right side of a sliding block, the temperature control channels are arranged at the position, provided with a guide rail plate, in the sliding block, and each temperature control channel is provided with an air inlet and an air outlet; and the ball head temperature control device comprises a wear-resistant copper pad arranged in a ball head seat, a ball head screw rod doses relative movement in the wear-resistant copper pad, the wear-resistant copper pad is connected with the ball head seatthrough a screw, a seal ring is arranged between the wear-resistant copper pad and the ball head seat, and a spiral temperature control channel is arranged on the fitting surface of the ball head seat and the interior of wear-resistant copper pad. According to the device, the temperature of the guide rail plate is controlled to be stable, the guide rail plate can not be expanded due to heating temperature rise, the precision of a sliding block guide rail is kept stable, the stability of the ball head screw rod and the ball head seat is guaranteed, and the overall precision, production efficiency and machined product quality of the forging mechanical press are improved.

The invention discloses a die-cut knife mold and making method, which is characterized by the following: loading the die-cut blade on the knife mold board; displaying inclined plane among the joint of die-cut blades; coinciding the inclined plane tightly; joining the knife; setting the reinforced part under the joint part; inserting the blade and reinforced part in the knife mold board. The invention supports limits and protects the joint die-cut blade, which improves key part strength, precision, lifetime and product quality of knife mold board.

This invention discloses an environmental protection and energy-saving drier including a bracket, a baking unit and a cooling unit connected with the baking unit, in which the baking unit includes a compressor and a condenser connected with it and a heat exchanger in between, the cooling unit includes an expansion valve, an evaporator and a four-way valve, one end of the expansion valve is connected with the condenser, the other end is connected with the evaporator by the four-way valve, the other end of the evaporator is connected with the compressor, the baking unit and the cooling unit areset in the bracket, which can recover and utilize waste heat of cold water set and turn heat of low quality to that of high quality to realize waste heat recovery and environmental protection.

The invention relates to the field of high-end equipment manufacturing industry, in particular to a precision and high-efficiency hot die forging press, including a frame, and the frame is equipped with a forging extrusion force heavy-duty control device, a pressure pin unloading device, Crankshaft bearing bush temperature control device, slider guide temperature control device, ball head temperature control device and clutch temperature control device. The forging force heavy-duty control device can meet the automatic and precise regulation of the forging force under heavy load, and the pressure pin unloading device can float the pressure pin upwards to reduce the rotation torque and the resistance in the transmission link. The temperature control device controls the temperature of the bearing bush precisely, and at the same time performs efficient sealing and thin oil lubrication; the clutch temperature control device is used to realize precise and efficient temperature control of the clutch; the slider guide rail temperature control device and the ball joint temperature control device are used to cool the friction pair Temperature control effectively improves the transmission accuracy, efficiency, reliability and product quality of the equipment, and realizes intelligent operation and maintenance, automatic control and connection.

The invention relates to a technology of a direction conversion device of a manufacturing engineering conveyor line of a glass plate for a liquid crystal display device, in particular to a pneumatic spiral direction-converted conveyor. In order to more stably convert the conveying direction of a heavy-weight large-size glass plate, a balanced level state is integrally kept by uniformly dispersingpower in the ascending / descending action process of an upper stand provided with trip rollers in an arraying way so that partial subsidence is not generated, therefore bad influence is ensured not tobe caused on the glass plate and the quality of processed products is also enhanced when the direction of the large-size glass plate is converted.

The invention provides a mold core-pulling anti-retraction mechanism, which includes a mold body, a driving device installed on the mold body, a transmission part connected to the output end of the driving device, an inner drawing fixing block, and a driving device installed on the inner drawing fixing block. The inner tap and the anti-retraction block are provided with a guide groove extending along the inner and outer directions in the inner drawer fixed block, the anti-retraction block is embedded in the guide groove, the driving part is provided with an active part, and the anti-retraction block is provided with There is a passive part matched with the active part, and the mold body is provided with a limit groove; when the driving device pushes the transmission part to move forward, the transmission part pushes the anti-retraction block, the inner drawing fixed block, and the inner tap to move forward , and the transmission part pushes the anti-retraction block to protrude outwards and embeds it in the limit groove of the mold body; when the driving device pulls the transmission part to move backward, the transmission part pulls the anti-retraction block to shrink inward and exit the limit slot, and the transmission member pulls the anti-retraction block, the inner drawer fixing block, and the inner tap to move backward.
