Description

Technical Field

[0001] The utility model relates to the technical field of chain links, and more specifically, to a forging device for chain links. Background Technique

[0002] The chain link is a core component of the crawler walking mechanism and is widely used in engineering machinery and equipment such as excavators, rotary drilling rigs, bulldozers, etc. When working, it needs to bear the machine weight, operating load, impact vibration force generated during operation, etc., and has relatively high requirements for overall strength, wear resistance, and impact toughness.

[0003] After the existing chain links are processed by stamping and forging, the chain links are taken out and placed on the conveying device and then conveyed to the quenching equipment for quenching treatment. Since there is a certain distance and a certain height difference between the mold on the stamping equipment and the conveying device, it is inconvenient to transfer the chain links. Generally, workers need to manually use a fixture to take out the chain links from the mold and walk to transfer them to the conveying device, which requires workers to move frequently, consuming a lot of physical strength and wasting time, affecting the forging efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a forging device for chain links in order to solve the above technical problems.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] A forging device for chain links includes a stamping device and a transfer groove arranged on one side of the stamping device;

[0007] The stamping device includes a U-shaped operation table, a lower mold is arranged on the U-shaped operation table, a hydraulic cylinder is arranged on the top of the U-shaped operation table, and an upper mold is fixedly installed on the output shaft of the hydraulic cylinder;

[0008] The transfer groove is composed of an inclined bottom plate and triangular plates vertically arranged on both sides of the bottom plate. The high side of the bottom plate is arranged close to the lower mold, and the low side of the bottom plate is arranged above the conveying device; support frames are respectively arranged on both sides of the bottom of the transfer groove, and a support plate is arranged on the top of the transfer groove, and a flushing device is arranged on the support plate;

[0009] The flushing device includes a servo electric cylinder fixedly connected to the support plate, a fixed seat fixedly connected to the piston rod of the servo electric cylinder, two nozzles respectively fixedly installed on the top and bottom of the fixed seat, and an air compressor for supplying air to the nozzles. The air outlet end of the air compressor is connected with a hose, the hose is connected with a three-way pipe, the first pipe orifice of the three-way pipe is connected with the hose, the second pipe orifice and the third pipe orifice of the three-way pipe are respectively communicated with one of the nozzles, and an electromagnetic valve is arranged on the first pipe orifice of the three-way pipe.

[0010] Working principle: The lower die is used to place the chain links. After the hydraulic cylinder punches the chain links on the lower die, the worker clamps out the chain links with a fixture and directly places them on the transfer groove. Under the action of free gravity, the chain links slide onto the conveying device through the bottom plate to complete the transfer. The setting of the transfer groove enables the worker to complete the transfer of the chain links in place after taking out the chain links, avoiding frequent walking of the worker and saving physical strength. When it is necessary to clean the upper die and the lower die, the servo cylinder is started. The piston rod of the servo cylinder drives the nozzle to move between the upper die and the lower die. The solenoid valve is started, and high-pressure air is ejected from the nozzle to wash the upper die and the lower die. It should be noted here that a controller is installed on the side of the C-shaped operation table close to the worker. The controller is electrically connected to the servo cylinder and the solenoid valve respectively. The controller is set nearby for the convenience of the worker to operate within reach. The settings of the hydraulic cylinder and the nozzle facilitate the cleaning of dust on the upper die and the lower die, eliminating manual cleaning and avoiding frequent replacement of tools, saving time and effort.

[0011] A U-shaped clamp is provided on the fixed seat, and the hose is fixedly installed on the fixed seat through the U-shaped clamp. The setting of the U-shaped clamp is used to fix the part of the hose close to the tee pipe to prevent the gravity of the hose from being applied to the tee pipe and pulling the tee pipe, causing the connection of the tee pipe to become loose.

[0012] A convex mounting groove is provided on the fixed seat, and the top and bottom of the convex mounting groove are respectively used to mount the nozzle. The setting of the convex mounting groove increases the operating space and facilitates the connection of the tee pipe and the nozzle.

[0013] The support frame includes a base, a support cylinder fixedly connected to the base, and a sliding cylinder sleeved on the support cylinder. The top of the sliding cylinder is fixedly connected to the bottom of the transfer groove. A threaded hole is provided on the outer wall of the support cylinder, and a fastening bolt is connected to the threaded hole. The setting of the fastening bolt is used to fix the sliding cylinder to prevent the sliding cylinder from sliding in the support cylinder, and the height of the transfer groove is adjusted by lifting and lowering the sliding cylinder.

[0014] A U-shaped protective cover is provided at the front end of the fixed seat. A plug rod is fixedly connected to the inner wall of the U-shaped protective cover, and a jack is provided on the side wall of the front end of the fixed seat. The plug rod and the jack are inserted and matched. The setting of the U-shaped protective cover is used to protect the nozzle on the fixed seat from being knocked.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In the present utility model, the setting of the transfer groove enables the worker to complete the transfer of the chain links in place after taking out the chain links, avoiding frequent walking of the worker and saving physical strength; the settings of the hydraulic cylinder and the nozzle facilitate the cleaning of dust on the upper die and the lower die, eliminating manual cleaning and avoiding frequent replacement of tools, saving time and effort; the setting of the U-shaped protective cover is used to protect the nozzle on the fixed seat from being knocked.
