The invention can effectively solve the problem that the sliding teeth of the screw are locked and difficult to disassemble, and the ejector rod and the ejector plate are easy to replace and disassemble, which can greatly improve the die-casting efficiency, reduce the efficiency of mold replacement, and also reduce the time for abnormal stop operation.

The invention relates to a control method for preventing a spindle bearing from being burnt. Before the spindle bearing of a machine tool is operated at a high speed, through a PLC control program, the spindle bearing is forcibly controlled to perform warming operation of in a stepped state. The PLC control program is used for controlling, and the machine tool is additionally controlled without any other hardware, so that the integrity of the spindle bearing is ensured, the replacement efficiency of the spindle bearing of the machine tool is lowered, the performance of the machine tool is improved, and the maintenance cost of the spindle bearing can be reduced.

The present application discloses an electric preheating heater suitable for a wind tunnel. The heater includes: a heater main body, a plurality of groups of heating parts, a power supply, a preheating temperature control system, an air inlet and an air outlet, wherein the heating The main body of the device includes an inner hollow cavity structure composed of a shell and a heat insulation layer; each heating part includes a heat storage element and two heating elements; multiple groups of heat storage elements are arranged in the cavity structure along the axis of the cavity structure, and the two heating elements are arranged in the cavity structure. A heating element is inserted into the heat storage element along the direction perpendicular to the axis of the cavity structure and passing through the casing and the heat insulation layer. The cold air in the structure is used for heating; the power supply is used to provide electrical energy for the heating element; the preheating temperature control system is connected to the power supply and used to control the power supply to provide electrical energy for the heating element. The present application solves the technical problems of low frequency of use and low efficiency of heaters in wind tunnels in the prior art.

The invention discloses a person and goods transporting platform for chimney ceramic vitrified brick construction. A fixed chassis and a rotating protecting rod are included, and the middle position of the lower end of the fixed chassis is provided with a threaded connection base; a threaded connection shock absorbing base device is sleeved with the inner position below the threaded connection base; the connected position of the fixed chassis and the shock absorbing base device is provided with the threaded connection base; and meanwhile the shock absorbing base device is changed into the threaded connection shock absorbing base device. When the threaded connection shock absorbing base device is damaged, the fixed chassis and the threaded connection shock absorbing base device are rotationally separated, replacing of the threaded connection shock absorbing base device is facilitated, and the shock absorbing effect of replacing of the threaded connection shock absorbing base device is also improved; in this way, the replacing efficiency is improved, and the shock absorbing performance of the whole device is also improved; and anti-swaying telescopic rods are installed around the person and goods transporting platform, so that the anti-swaying telescopic rods play a certain supporting role in the person and goods transporting platform, and using of the person and goods transporting platform is improved.

The invention discloses minitype and efficient mechanical plate material automatic bending equipment. The minitype and efficient mechanical plate material automatic bending equipment comprises an outer shell body, the front end face of the outer shell body is provided with a shaft sleeve, the shaft sleeve is internally connected with a shaft rod in a sleeving manner, the outer wall of the shaft rod is connected with a rotating roller in a sleeved manner, the center of the end portion of the rotating roller is fixedly provided with a fixed block, the inner wall of the fixed block is in fit withthe outer wall of the shaft rod, the surface of the shaft rod is provided with a square slot, the surface of the fixed block is provided with a square hole, and the square hole is internally providedwith a fixed rod. According to the minitype and efficient mechanical plate material automatic bending equipment, by means of the design of the fixed rod, the shape of the fixed rod is square, so thatthe fixed rod can be fixed with the square slot in the end portion of the shaft rod in a clamping closing manner to make the shaft rod be connected into a whole with the rotating roller and make theshaft rod drive the rotating roller to rotate, when the rotating roller needs to be replaced, the rotating roller can be disassembled by pulling the rotating roller out directly, and the situation that a flat key and a key slot further need to be aligned to perform fixing then in traditional replacement of the rotating roller, and because the flat key and the key slot are matched too tightly, therotating roller is inconvenient to disassemble in subsequent replacement of the rotating roller is avoided.

The invention discloses a bracket assembly used for LED chip packaging and relates to the technical field of LED brackets. The invention comprises a bottom box and a sealing cover. The bottom box is provided with a plurality of grooves on both inner walls opposite to each other. One inner wall of the groove is fixedly connected with a limit spring, and one end of the limit spring is fixedly connected with a block. A number of clamping holes matched with the clamping block, two suspenders are connected with symmetrical rotation on the top of the sealing cover, one end of the suspender is fixedly connected with a pulley, and a number of first elastic telescopic rods are fixedly connected on the side of the transmission belt circumference, one end of the first elastic telescopic rod The fixed connection has a block. The present invention adopts the design of sealing cover, clamping block, support plate, clamping hole, transmission belt, blocking block and T-shaped chute, which is easy to operate, firm in installation and not easy to fall off, and avoids the simple structure of the existing LED packaging bracket, which is inconvenient to disassemble. It reduces the maintenance or replacement efficiency of the LED lamp group, and the package is not firm and easy to fall off, which affects the service life of the LED package bracket.
