The invention discloses a stampings bonding prevention device for a stamping die and is suitable for punching of coiled materials. The stampings bonding prevention device for the stamp die comprises two rotary cylinders which are located on one side of the die, and the coiled materials go in from the side. The two rotary cylinders are tightly attached to each other and arranged up and down. Each rotary cylinder comprises an oil storage drum with two sealed ends and an oil impregnating layer which is arranged on the outer side of the oil storage cylinder. The oil impregnating layer has elasticity. A plurality of oil impregnating holes are uniformly formed in the circumferential surface of each oil storage cylinder. One ends of the oil storage cylinders are connected with a punching oil conveying system through pipelines. A damping layer with elasticity is arranged between each oil storage cylinder and each oil impregnating layer. A plurality of oil impregnating cylinders are uniformly arranged on the circumferential surface of each damping layer and embedded in each oil impregnating layer. Oil outlet holes which penetrate through the inner surface of each damping layer are formed in each oil impregnating cylinder. Kerfs which are communicated with the oil outlet holes are uniformly arranged on the circumferential surface of each oil impregnating cylinder. The stampings bonding prevention device for the stamp die can prevent stampings from bonding with the die, and therefore continuous punching can be achieved, and influence of machine halt on production efficiency is avoided. Besides, the stampings bonding prevention device for the stamp die is beneficial for prolonging service life of the die and improving punching quality of products.

A continuous punching device for linear pipes, comprising a base, a punching mechanism arranged on the base, a sliding seat arranged on the base capable of moving horizontally and horizontally, a lateral movement mechanism for driving the sliding seat to move laterally, and a sliding seat arranged on the sliding seat The clamping mechanism used to clamp one end of the straight pipe, and the control device connected with the punching mechanism and the lateral movement mechanism respectively. The punching mechanism includes a mold base, a mandrel and a punching mechanism. There is a through hole that extends horizontally and can be inserted into by a straight pipe, the top surface is formed with a first punching hole that communicates with the through hole, and the bottom surface is formed with a discharge hole that is connected with the through hole; the core mold is set on the In the through hole of the mold base, a second punching hole opposite to the first punching hole is formed on the mandrel; the punching mechanism includes a punch that can move up and down relative to the first and second punching holes and a driving member that drives the punch to move up and down , the present invention has the advantages of simple structure, convenient operation and high punching efficiency.

The invention belongs to the field of vegetable transplanting and relates to a novel perforator for vegetable transplanting. The novel perforator comprises a pressure bar, a casing pipe and a digging bucket. The pressure bar is provided with a wedge-shaped clamp with a downward wedge-shaped structure. Upper and lower ends of the casing pipe are respectively provided with an opening and an enclosed port. The upper end of the casing pipe sleeves the lower end of the pressure bar. The side wall of the casing pipe is provided with a clamping hole. Multiple movable rods are hinged to the lower end of the casing pipe. The other ends of the movable rods are respectively hinged to and uniformly distributed on the same circumference in the digging bucket. The top of the digging bucket is uniformly provided with multiple extending-retracting folding lines connected to the bottom of the digging bucket and the bottom of the digging bucket is provided with a conical cap. In use, a handle is held, the novel perforator is downward inserted into soil and then the pressure bar is lifted so that the soil is dug up along with the digging bucket and thus soil does not fall off and labor efficiency is improved.

The invention provides a continuous forming device for a central tube of a filter, comprising an unwinding device; a punching device installed on the right side of the unwinding device; a pushing device installed on the right side of the punching device; and a pushing device installed on the right side of the pushing device The coiling device; the cutting device installed at the front end of the coiling device, the cutting device includes a rotating shell, the center of the rotating shell is provided with a center hole matching the coiling shaft, and the cutting wheel is fixed on the On the installation shaft, one end of the installation shaft is fixed on the rotating shell, the positioning guide wheel is installed on one side of the center hole of the rotating shell, and the pneumatic pull rod is installed on one side of the rotating shell, the pneumatic pull rod and the rotating shell They are fixedly connected by a tie rod shaft. The continuous forming device of the central tube of the filter can realize automatic unwinding, punching, stable feeding, automatic coiling and cutting of the coiled plate, realize continuous processing and forming of the central tube, and greatly improve the processing efficiency and quality of the central tube.

A continuous punching device for U-shaped pipes, comprising a base, two punching mechanisms symmetrically arranged on the base at the front and rear, a sliding seat arranged on the base that can move horizontally and horizontally, and a lateral movement mechanism that drives the sliding seat to move laterally , the clamping mechanism arranged on the sliding seat for clamping the U-shaped pipe in the middle, the control device connected with the punching mechanism and the lateral movement mechanism respectively, the punching mechanism includes a fixed frame, a movable frame, a mold base, and a mandrel , driving parts and punches, the present invention has the advantages of simple structure, convenient operation and high punching efficiency.

The invention relates a blanking device. The blanking device comprises a rack, a blanking mechanism, a feeding mechanism, a driving mechanism and a transmission mechanism, wherein the rack is provided with a support platform for supporting a material strap; the blanking mechanism is movably arranged on the rack, can ascend and descend relative to the rack and blanks and bends materials on the material strap on the support platform when descending; the feeding mechanism is arranged on the rack and linked with the blanking mechanism; and the driving mechanism is arranged on the tack, the transmission mechanism is connected between the driving mechanism and the blanking mechanism, the driving mechanism drives the blanking mechanism to ascend and descend through the transmission mechanism, and the feeding mechanism is driven to clamp and drive the material strap to move forwards when the blanking mechanism ascends, so that the blanking mechanism can continually blank and bend the materials on the material strap. According to the blanking device, the blanking mechanism and the feeding mechanism are linked and share the same power source, and the blanking device is accurate in processing and high in processing efficiency.
