Description

Technical Field

[0001] The utility model relates to the technical field of rivet processing equipment, and more specifically, to a runner retracting mechanism for rivet production. Background Art

[0002] In the production process of rivets, the runner is an important component. The design and manufacture of the runner have a direct impact on the quality and production efficiency of rivets. The runner is responsible for transporting raw materials to the position where the rivets are formed, ensuring the uniform material of the rivets and avoiding quality problems caused by uneven material. When forming the rivets, the runner needs to be retracted.

[0003] In the prior art, almost all the runner retractions of riveting machines are controlled by air cylinders. When the main air cylinder shaft of the riveting machine does not descend, the air cylinder retracts, pulling the end of the runner back between the upper die and the lower die; when the main air cylinder shaft descends, the air cylinder pushes the runner out, pushing the runner away from the axis of the main air cylinder so that the main air cylinder shaft does not collide with the runner. However, there are some problems in its use. When any one of the factors such as insufficient air pressure, circuit failure, solenoid valve not working, or working abnormally, air leakage in the air circuit, and air pipe detachment occurs once, the runner will be damaged and scrapped when the air cylinder descends, and the equipment cannot be automatically stopped when the runner is damaged, posing a safety hazard.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and design a runner retracting mechanism for rivet production.

[0006] To achieve the above purpose, the technical solution of the utility model is a runner retracting mechanism for rivet production, including a base. A stamping lower die is installed at the upper end of the base, and a stamping upper die that can move up and down is arranged above the base. A support frame is installed at the upper end of the base. One side of the upper end of the support frame is hinged with a rivet runner. A pushing mechanism is installed on the base, and an emergency stop mechanism is installed on the base.

[0007] The pushing mechanism includes L-shaped support rods installed on both sides of the end of the rivet runner. A pulley is installed at one end of the L-shaped support rod. Lifting blocks are installed on both sides of the lower end of the stamping upper die. A limiting groove is opened on the lifting block. A reset block is installed on the support frame. The reset block and the upper end of the rivet runner are connected by a reset spring.

[0008] The emergency stop mechanism includes a fixed block installed on the base. An emergency stop switch is installed on the fixed block. A pushing frame is arranged on one side of the fixed block. When the L-shaped support rod is disconnected from the rivet runner, the pushing frame can press the emergency stop switch.

[0009] Furthermore, the pushing frame includes a pressing table located on one side of the emergency stop switch. Guide blocks are installed at the upper and lower ends of one side surface of the pressing table. A plurality of guide grooves are formed on the fixed block, and one end of the guide block extends into the guide groove. Inclined surfaces are provided on both sides of the pressing table. One end of the L-shaped support rod is installed with a telescopic rod, and the telescopic end of the telescopic rod is installed with a pressing wheel. A pressing frame is installed inside the pressing table.

[0010] Furthermore, the pressing frame includes a first pressing plate installed at one end of the inner surface of the pressing table. A lever installed on the fixed block is provided on one side of the emergency stop switch. A second pressing plate is installed at the other end of the inner surface of the pressing table. When the pressing table moves to one side, the emergency stop switch can be pressed down through the first pressing plate. When the pressing table moves to the other side, the emergency stop switch can be pressed down through the second pressing plate and the lever.

[0011] Furthermore, the limiting groove includes a long groove located at the lower end of the lifting block, and an inclined groove is provided at the upper end of the long groove.

[0012] Furthermore, a counter is installed on the support frame, and the counter can be pressed down when the rivet runner retracts.

[0013] Advantages of the present utility model: Through the action of the limiting groove and the pulley, when the stamping upper die moves downward, the rivet runner can be pushed away, thereby avoiding the stamping upper die. When the stamping upper die moves upward, under the action of the return spring, the rivet runner can return to its original position and facilitate feeding. When the L-shaped support rod is disconnected from the rivet runner, the pushing frame can automatically press the emergency stop switch, thereby stopping the operation of this device and reducing potential safety hazards;

[0014] When the L-shaped support rod moves in the direction close to the fixed block, the telescopic rod can be compressed. At this time, the pressing table will not move left and right, nor will it trigger the emergency stop button. When one side of the L-shaped support rod is disconnected from the rivet runner, the L-shaped support rod on the other side can squeeze the telescopic rod, and then under the elastic force of the telescopic rod, the pressing table can be pushed, which is convenient for pressing the emergency stop button and makes the use safer.

[0023] The process of retracting the runner during rivet production by this device is as follows: The raw material can be moved above the stamping lower die 2 through the rivet runner 5. Then, the stamping upper die 3 is moved downward. When the stamping upper die 3 moves, the lifting block 8 can be pushed downward. Then, under the action of the limiting groove 9, the pulley 7 and the L-shaped support rod 6 can be pushed to one side, and the rivet runner 5 is pushed. At this time, the reset spring 11 is stretched. After the rivet is formed, the stamping upper die 3 is moved upward, driving the lifting block 8 and the limiting groove 9 upward. Then, under the pulling force of the reset spring 11, the rivet runner 5 returns to its original position. When the L-shaped support rod 6 is disconnected from the rivet runner 5 after being used for a period of time, the emergency stop switch 13 can be automatically pressed by the pushing frame 14, and this device can be shut down, reducing potential safety hazards.
