Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a bolt end pressing head device. Background Art

[0002] A bolt is a metal fastener characterized by a threaded surface and usually a nut at one end. It is mainly used to connect or fix two or more parts by threading and is widely used in mechanical equipment, structural engineering, and various assemblies. The selection of bolts depends on its characteristics such as diameter, length, and thread type to ensure a safe and reliable connection during application. The processing of bolts usually involves a variety of processes, among which stamping is one of the common processing methods.

[0003] However, during the current bolt stamping operation, workers directly place the bolts with red-hot ends into the mold, and use a punch to stamp the ends of the bolts to deform them. However, the bolts are not fixed in the mold and are easily displaced during the stamping process, resulting in unstable shapes and sizes of the bolts after stamping, making it difficult to ensure processing accuracy. In addition, workers need to use tweezers to remove the bolts from the mold, which not only adds extra time and labor costs and reduces production efficiency, but the removed bolts may still be very hot, posing burns or other safety risks. Utility Model Content

[0004] The utility model aims to provide a bolt end pressing head device which can fix bolts and quickly take out formed bolts.

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

[0006] A bolt end pressing head device comprises a bottom plate, a left half mold and a right half mold are slidably mounted on the upper surface of the bottom plate, an inner groove is provided on the inner wall of the left half mold and the right half mold, and clamping blocks are arranged inside the two inner grooves. Vertical poles are installed at the four corners of the upper surface of the bottom plate, 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, a lifting plate is installed at the end of the telescopic end of the hydraulic cylinder, a punch is installed on the lower surface of the lifting plate, a clamping mechanism is arranged on the outer side of the lifting plate and the clamping block, and the clamping mechanism can drive the two clamping blocks to move inward while the lifting plate descends. A through hole is arranged on the bottom plate, and a material taking mechanism capable of driving the left half mold and the right half mold to move in the opposite direction is arranged at the bottom of the bottom plate.

[0007] It can be seen that through the setting of the clamping mechanism, when the hydraulic cylinder drives the punch to descend to punch the bolt, it can drive the two clamps to move inward at the same time and clamp on the outside of the bolt, so that the bolt can be fixed, avoiding displacement during the stamping process, resulting in unstable shape and size of the bolt after stamping, and difficulty in ensuring processing accuracy. Through the setting of the material taking mechanism, after stamping, the left half mold and the right half mold can be driven away from each other, so that the formed bolt can fall from between the two and into the through hole, thereby avoiding manual removal of the bolt, which results in additional time and labor costs, reduces production efficiency, and there are burns or other safety risks.

[0008] Furthermore, the clamping mechanism includes two first wedge blocks respectively arranged on the outside of the left half mold and the right half mold, the opposite surfaces of the two first wedge blocks are connected to guide rods, the ends of the guide rods are connected to the clamping blocks, the outer surface of the guide rods is sleeved with springs, and two second wedge blocks are installed on the lower surface of the lifting plate, and the two second wedge blocks correspond to the two first wedge blocks respectively.

[0009] When the hydraulic cylinder drives the lifting plate to descend, the two second wedge blocks at the bottom of the lifting plate squeeze the two first wedge blocks at the same time, thereby driving the two first wedge blocks to move inward at the same time, and driving the two clamping blocks to clamp on the outside of the bolt at the same time through the connection of the guide rod, thereby achieving the purpose of fixing the bolt before stamping, thereby improving the processing accuracy; when the stamping is completed and the hydraulic cylinder drives the lifting plate to rise, the second wedge block separates from the first wedge block, and the compressed spring releases the elastic force at this time, thereby driving the clamping block to separate from the bolt and canceling the fixation.

[0010] Furthermore, the material picking mechanism includes a gear ring rotatably installed on the lower surface of the base plate, and the gear ring is coaxially arranged with the through hole, two L-shaped gear plates parallel to each other are slidably installed on the lower surface of the base plate, and the two L-shaped gear plates are meshed and connected with the gear ring, two through grooves are provided on the base plate, the outer surfaces of the two L-shaped gear plates are connected with connecting blocks, and the ends of the two connecting blocks are respectively connected with the left half mold and the right half mold, an electric push rod is installed on the side surface of the base plate, and the end of the telescopic end of the electric push rod is connected with one of the L-shaped gear plates.

[0011] When the bolt is formed, the electric push rod can be started, and its telescopic end drives the L-shaped toothed plate connected to it to slide. Through the transmission action of the gear ring, the other L-shaped toothed plate can slide in the opposite direction at the same time. Therefore, when the two L-shaped toothed plates slide in opposite directions, the connecting action of the connecting block can drive the left half mold and the right half mold to move away from each other, so that the bolt between the two can fall from the through hole, thereby completing the purpose of automatically removing the bolt.

[0012] Furthermore, support columns are installed at the four corners of the lower surface of the bottom plate, a placement plate is installed between the four support columns, and a material receiving box is arranged on the upper surface of the placement plate.

[0013] When the bolts fall from the through holes, they can fall into the collecting box, thus completing the collection of the bolts.

[0014] Furthermore, linear bearings are installed at the four corners of the lifting plate, and the linear bearings are slidably installed on the vertical rods.

[0015] By setting the linear bearing, the stability of the lifting plate during the lifting process can be improved, thereby improving the punching accuracy of the punch on the bolt.

[0016] Furthermore, the outer surface of the first wedge-shaped block is connected to two guide rods, and the two guide rods are arranged in parallel up and down.

[0017] By providing the two guide rods, the connection strength between the clamping block and the first wedge block can be enhanced, thereby increasing the service life. BRIEF DESCRIPTION OF THE DRAWINGS
