Description

Technical Field

[0001] The invention relates to a copper cutting rope shaping and closing device, belonging to the field of pyrotechnic device assembly. Background Art

[0002] Copper cutting rope is widely used in strategic and tactical missiles, launch vehicles and other models. In the production process, it needs to be rolled into a "V" shape. During the rolling process, the copper cutting rope will form an arc shape in the direction of rolling. However, in the assembly process, the copper cutting rope needs to be bent into a ring shape at 90° in the direction of its trend, and then it needs to be left to stand for 30 minutes. The basic shape of the copper cutting rope is finalized and it can be assembled and closed. When closing, it needs to be manually placed in a specific tooling, and then the assembly process is completed by pressing the retaining edge of the tooling into a 30° chamfer. The labor intensity of the operation personnel is high and the efficiency is not high.

[0003] Therefore, there is an urgent need for a semi-automatic forming and closing device for copper cutting rope. Summary of the invention

[0004] The present invention provides a copper cutting rope shaping and closing device, which reduces labor intensity and alleviates the problem of uncontrollable production speed caused by uneven force during manual production.

[0005] The present invention is achieved by the following technical solutions:

[0006] A copper cutting rope shaping and closing device comprises a device frame 2, a follow-up turntable 7 is installed on the table 4 of the device frame 2, the output shaft of the pneumatic motor 3 is fixedly connected to the follow-up turntable 7, a quick clamp 6 is installed on the end face of the follow-up turntable 7 and a guide groove 7-1 along the circumferential direction is provided, an upper table 8 is fixedly connected to the top of the table 4, a rope cutting cylinder 9 and a rope pressing cylinder 10 are fixedly connected to the upper table 8, a cutter 13 and a rope cutter 12 are installed at the lower end of the rope cutting cylinder 9, and a roller pressing wheel and a closing wheel are replaceably installed at the lower end of the rope pressing cylinder 10.

[0007] The lower end of the cable cutting cylinder 9 is provided with a cable cutting device 12 via a cable cutting device bracket 11 and a cutter 13 via a cutter mounting block 9-3.

[0008] The cable cutter 12 is provided with a hole through which the cutting cable passes and a slot through which the cutter 13 passes, and the hole penetrates the slot.

[0009] A protective device is provided on the front of the upper table 8 and is installed on the table 4.

[0010] The protective device is a polycarbonate sheet with a thickness of 15mm.

[0011] The output shaft of the pneumatic motor 3 is fixedly connected to the main transmission shaft 3-4. Two deep groove ball bearings 3-2 and a thrust ball bearing 3-6 that bears the downward pressure of the cylinder are installed between the main transmission shaft 3-4 and the active turntable 3-5. The main transmission shaft 3-4 and the active turntable 3-5 are connected by bolts. The main rotating disk 3-5 is connected to the follower turntable 7 by pins, and the active turntable 3-5 is fixedly connected to the table 4.

[0012] The lower end of the main transmission shaft 3-4 is fixedly connected with a transmission chassis 3-1, which is located below the table 4 and is used to fix the deep groove ball bearing 3-2 and the thrust ball bearing 3-6.

[0013] The maximum rotatable angle of the quick clamp 6 is 170°.

[0014] The pneumatic motor 3 is equipped with two left and right foot valves, which are two-position three-way mechanical valves. The two sides are alternately ventilated. The right foot valve controls counterclockwise rotation, and the left foot valve controls clockwise rotation for pneumatic point control.

[0015] The cable-pressing cylinder 10 is a three-axis cylinder with a two-position five-way reversing valve.

[0016] The beneficial effects of the present invention are:

[0017] (1) The present invention designs a new way of winding the rope. In the old way, the tooling plate is fixed, and the roller mouth / closing wheel rotates. The rotation radius is large, and the operator needs to follow one circle for one circle. The new way of winding the rope is that the tooling plate rotates, the roller mouth / closing wheel remains stationary, and the operator also remains in a fixed position.

[0018] (2) The roller / closing wheel is installed by using an adjustable stroke cylinder. Since the roller wheel and the closing wheel need to maintain different heights, the stroke of the adjustable stroke cylinder needs to be adjusted during closing.

[0019] (3) Use quick clamps, which are relatively easy to operate in the current industrial field, to replace the original tooling screw fixing method. It is fast and simple, easy to open and close, and has strong replaceability and maintainability.

[0020] (4) The method of cutting the excess copper rope is changed to using a double-acting cylinder driven by a cylinder that can move up and down for cutting, which has high work efficiency and neat cutting surfaces.

[0021] (5) The old production tooling had no safety protection device, and it was impossible to set up an effective safety protection device. The new shaping device has a 15mm thick polycarbonate sheet in front, which can protect the life safety of the operator to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention uses a pneumatic motor as a power source, a transmission shaft is connected to the pneumatic motor, and a flange is connected to the transmission shaft. When the pneumatic motor rotates, the transmission shaft also rotates, and the transmission shaft transmits torque to the flange. The flange is fixed by a fixing pin and a cable tool. At this time, the cable tool also rotates, and the copper cable that has been pressed into the "V" groove is fixed by a current quick clamp. The pneumatic motor is used to replace the manually rotated wheel, and two left and right foot valves are installed. The right foot valve controls the counterclockwise rotation, and the left foot valve controls the clockwise rotation. Pneumatic point control is performed, and a three-axis cylinder is used to install a closing wheel and a roller wheel for closing and roller forming respectively. After the roller forming is completed, the copper cable needs to be cut into a circle, and the excess part is marked. After marking, the copper cable with the marked line can be cut at the cable cutting position of the equipment. There is a protective plate with a thickness of 15 mm on the front of the device to protect the safety of the operator when the operator is operating.

[0035] The device as a whole uses compressed air as the power source. The foot valve of the device is a two-position three-way mechanical valve, and the two sides are alternately ventilated. The three-axis cylinder of the device is a two-position five-way reversing valve, which is used for compound-acting cylinders.

[0036] The present invention will be described below with reference to the accompanying drawings:

[0037] like Figure 1-12 As shown, the present invention provides a novel copper cutting rope shaping and closing device. The device includes a device frame 2, a moving part, and a protective panel. The end of the copper cutting rope is placed in the guide groove 7-1 of the follower turntable 7, and the rope pressing cylinder 10 is installed with a roller pressing wheel to press the copper cutting rope into the guide groove 7-1 according to the shape. The quick clamp 6 fixes the copper cutting rope already in the guide groove 7-1 until the entire copper cutting rope is completely placed in the guide groove 7-1. After the copper cutting rope is statically formed, the closing wheel is replaced on the rope pressing cylinder 10, and the entire copper cutting rope is placed on the follower turntable 7. The closing wheel closes the rope. After the closing wheel closes one circle, it ensures that the copper cutting rope is covered with one circle. Then, the excess part of the copper cutting rope is marked, and the marked line can be seen through the hole on the rope cutter 12 through the gap of the rope cutter, and the rope cutting position is just aligned at this time. The rope cutting cylinder 9 is pressed down, and the cutter cuts the copper cutting rope from the marked line.

[0038] The specific movement mode of the transmission part is as follows: the pneumatic motor drives the main transmission shaft to rotate. Two deep groove ball bearings are installed between the main transmission shaft and the active turntable to ensure that there is no friction between the main transmission shaft and the equipment during rotation. Another thrust ball bearing is installed to bear the downward pressure of the cylinder. The main transmission shaft drives the active turntable to be connected by bolts, which drives the main rotating disk to rotate. The main rotating disk is connected to the follower turntable through pins, thereby driving the follower turntable to rotate.

[0039] like Figure 4The mechanical quick clamp used in this device is installed on the follow-up turntable. It is fixed on the turntable with 4 M3 bolts. Its maximum holding force is 680N and the maximum rotation angle is 170°.

[0040] The working principle of the present invention is:

[0041] Put the end of the copper cutting rope to be shaped into a guide groove, and the rope pressing cylinder drives the roller pressing wheel to press down. After pressing, the pneumatic motor indirectly drives the follower turntable to rotate, and the friction force drives the copper cutting rope to move forward. In the tangential direction of the guide groove of the follower turntable, the copper cutting rope can smoothly enter the guide groove. After the shaping is completed, replace the closing wheel, adjust the height of the rope pressing cylinder, and close the rope. After the closing is completed, mark the rope. After marking, use the rope cutter to cut off the excess rope head. After cutting, remove the cutting rope loop from the equipment.
