Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a bolt pressing head device which is convenient for replacing a mold. Background Art

[0002] A bolt is a commonly used mechanical connection element, usually made of metal, with a rod-like structure and external threads. It is used to connect or fix objects together and is often used in conjunction with a nut. By rotating the bolt, the position of the nut can be adjusted to achieve the effect of tightening or loosening. Therefore, it is widely used in the fields of engineering and manufacturing. When processing the bolt, the prefabricated pipe is generally placed in the lower die and its head is pressed using a punch.

[0003] However, the existing lower mold is usually installed on the processing table with bolts, which makes it troublesome to replace the mold and consumes more time. Especially when different types of bolts need to be processed frequently, it will have a certain impact on production efficiency. In addition, after the prefabricated pipe is stamped, the debris on its surface is easy to fall into the lower mold, and manual cleaning is more troublesome. If the debris is not cleaned up, it will cause defects such as indentation on the surface of subsequent products, affecting product quality. Utility Model Content

[0004] The utility model aims to provide a bolt pressing head device which is convenient for replacing a lower mold and can clean up debris in the lower mold.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A bolt pressing device for facilitating mold replacement includes a processing table, a lower mold is arranged on the upper surface of the processing table, clamps are slidably installed on the four sides of the upper surface of the processing table located at the lower mold, and a clamping mechanism capable of driving the four clamps to move toward the lower mold at the same time is arranged at the bottom of the processing table. A driving mechanism that cooperates with the clamping mechanism is arranged on the lower side of the processing table. Vertical poles are installed at the four corners of the upper surface of the processing table, and a top plate is installed on the top of the four vertical poles. A hydraulic cylinder is installed on the upper surface of the top plate, and a punch is installed at the end of the telescopic end of the hydraulic cylinder. An L-shaped support rod is rotatably installed on the upper surface of the processing table, and a motor is installed on the lower surface of the processing table. The output shaft of the motor is connected to the L-shaped support rod, and a cleaning mechanism is arranged on the outer surface of the L-shaped support rod.

[0007] It can be seen that through the transmission cooperation between the clamping mechanism and the driving mechanism, the four clamps can be pressed on the four sides of the lower mold to fix it at the same time. When the four clamps cancel the pressure on the four sides of the lower mold at the same time, the lower mold can be taken out, so that the lower mold can be quickly replaced, reducing the time consumed in replacing the lower mold and improving production efficiency. The cleaning mechanism is driven by the motor to rotate to the top of the lower mold, so that the debris dropped from the lower mold can be absorbed, thereby achieving the purpose of quick cleaning and reducing the labor workload of workers.

[0008] Furthermore, the clamping mechanism includes a cross plate arranged at the bottom of the processing table, four through slots are opened on the processing table, wedge plates are installed at the four ends of the cross plate, and the wedge plates are arranged in the through slots, wedge blocks are installed on the outer surfaces of the four clamping plates, the wedge plates are adapted to the wedge blocks, a threaded rod is passed through the interior of the cross plate and threadedly connected, and the top of the threaded rod is rotatably connected to the bottom of the processing table.

[0009] Since the four groups of through grooves and wedge plates limit the cross plate, when the threaded rod is rotated, the cross plate can be driven to rise and fall vertically. By making the cross plate rise, it drives the four wedge plates to squeeze the four wedge blocks at the same time, thereby driving the four clamps to press on the four sides of the lower mold to fix it. When the threaded rod is rotated in the opposite direction to drive the four wedge plates to descend, the clamping and fixing of the lower mold by the clamps can be cancelled, so that the lower mold can be taken out for replacement.

[0010] Furthermore, the driving mechanism includes a U-shaped plate installed at the bottom of the processing table, and the bottom of the threaded rod is rotatably connected to the U-shaped plate, a rotating shaft is rotatably connected between the two side walls of the U-shaped plate, a worm is installed on the outer surface of the rotating shaft, a worm wheel is installed on the outer surface of the threaded rod, the worm wheel is meshingly connected to the worm, and a handwheel is installed on the end of the rotating shaft.

[0011] When the handwheel is rotated, it drives the shaft to rotate, and the shaft drives the worm to rotate. Since the worm and the worm wheel are meshed with each other, the purpose of driving the threaded rod to rotate can be achieved. Moreover, the worm and the worm wheel have good self-locking properties, which can prevent the threaded rod from reversing and causing the lower mold to loosen.

[0012] Furthermore, the cleaning mechanism includes a fan installed on the upper surface of the L-shaped support rod, a dust filter box is installed on the upper surface of the L-shaped support rod, and the suction end of the fan is connected to the dust filter box, the outer surface of the dust filter box is connected to a connecting pipe, the end of the connecting pipe is connected to a bellows, an air collecting hood is provided at the bottom of the L-shaped support rod, the end of the bellows is connected to the air collecting hood, a filter screen is installed inside the dust filter box, and a collection box is provided inside the dust filter box at the lower side of the filter screen.

[0013] When the fan is started, the suction force it generates acts on the air collecting hood, which can be used to suck out the debris inside the lower mold. The sucked-out debris enters the debris filter box through the bellows and the connecting pipe, and falls into the collection box after being intercepted by the filter, thereby achieving the purpose of collecting the debris.

[0014] Furthermore, a groove is provided on the upper surface of the processing table, a top block is arranged inside the groove, an inner groove is provided inside the processing table, a first electric push rod is installed inside the inner groove, and the end of the telescopic end of the first electric push rod is connected to the top block.

[0015] When the prefabricated pipe is stamped, the first electric push rod can be started, and its telescopic end drives the top block to rise, so that the pipe can be pushed up to facilitate its removal from the lower mold.

[0016] Furthermore, a first ventilation hole is provided on the lower surface of the processing table, and the first ventilation hole is connected to the inner groove. A second ventilation hole is provided on the upper surface of the processing table, and both ends of the second ventilation hole are respectively connected to the inner groove and the interior of the lower mold. A second electric push rod is installed on the upper surface of the L-shaped support rod, and the end of the telescopic end of the second electric push rod is connected to the wind collecting hood.

[0017] When the motor drives the cleaning mechanism to rotate to the top of the lower mold, the second electric push rod is started, and its telescopic end drives the air collecting hood to fit the upper surface of the lower mold. Then the fan is started. The suction force generated can allow external air to enter the interior of the lower mold from the first ventilation hole, the inner groove and the second ventilation hole, thereby reducing the loss of suction force and being able to clean up the debris inside the lower mold, avoiding defects such as indentations on the surface of subsequent products, which affects product quality.

[0028] When in use, the prefabricated pipe with the end portion red-hot is inserted into the lower mold 101, and the hydraulic cylinder 105 is started. The hydraulic cylinder 105 drives the punch 106 to descend to punch the end portion of the prefabricated pipe, thereby completing the pressing head processing of the bolt.
