Description

[Technical field]

[0001] The utility model relates to the technical field of bolt production and processing, in particular to the technical field of a bolt cold heading machine. [Background technology]

[0002] A bolt is a mechanical part, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut and is used to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, the bolt connection is a detachable connection. Therefore, when producing and processing bolts, a cold heading machine is required to cold extrude the bolts. Most of the existing cold heading machines for bolt processing are not convenient for automatic loading and unloading. When in use, manual loading is required, which is time-consuming and labor-intensive. In addition, the mold cannot be replaced and adjusted according to the shape of the bolt, and the scope of application is limited.

[0003] In order to solve the problems raised in the background technology, publication number CN216502139U discloses a cold heading machine for bolt processing, in which the material is conveyed to the side of the electromagnetic suction plate by a movable splint, the cutting knife cuts the material, the electromagnetic suction plate pushes the material to the side of the mold, and three pressure rods perform cold heading processing on the material in sequence. When the processing is completed, the discharge push rod sets the already formed screws for discharge, thereby completing the processing of the screws, avoiding the inefficiency caused by manual loading and unloading, and can greatly improve the processing efficiency of the device. By replacing the pressure rod and the mold, the device can be adjusted as needed, and the scope of application of the device can be expanded. The linkage plate cooperates with the fixed splint and the movable block to facilitate pushing the material to the required position. The movable splint can be adjusted on the linkage plate, so that the length of material conveying can be adjusted, and it can also be adjusted according to the size of the material. However, the structure still has the following shortcomings:

[0004] 1. The cold heading machine lacks a fixed structure, so the bolts are prone to shift during processing, thus affecting the processing quality.

[0005] 2. The cold heading machine lacks a structure to accelerate cooling, so it is unable to quickly cool the bolts, resulting in slower bolt production. [Contents of the utility model]

[0006] The utility model aims to solve the problems in the prior art and provides a bolt cold heading machine, which can fix the bolts during processing, ensures the processing quality, and accelerates the speed of bolt production by using a cooling mechanism.

[0007] To achieve the above-mentioned purpose, the utility model proposes a bolt cold heading machine, comprising a support plate, support legs, a support frame, a hydraulic cylinder, a lifting column, a punching head, a workbench, a positioning hole, a fixing mechanism, and a cooling mechanism. A plurality of support legs are arranged below the support plate, and a support frame with an L-shaped structure is arranged on the upper rear side of the support plate. A hydraulic cylinder is arranged above the support frame, and a lifting column is arranged below the support frame. The output end of the hydraulic cylinder passes through the support frame and is connected with the lifting column. The end of the lifting column is connected with a punching head for cold heading bolts. A workbench is arranged above the support plate, and a positioning hole is opened on the workbench. Fixing mechanisms for fixing bolts are symmetrically arranged on both sides of the inner wall of the positioning hole, and a cooling mechanism for accelerating the cooling of the bolts is arranged on the support frame.

[0008] Preferably, an anti-slip pad is provided under the supporting leg.

[0009] Preferably, the punching head is located directly above the positioning hole, and the punching head and the positioning hole are used in coordination.

[0010] Preferably, the fixing mechanism includes a threaded rod, a rotating handle, and a fixing block. The threaded rod is located on both sides of the interior of the workbench. One end of the threaded rod passes through the outside of the workbench and is rotatably connected to the rotating handle, and the other end of the threaded rod passes through the outer wall of the positioning hole and is connected to the fixing block.

[0011] Preferably, the cooling mechanism includes a driving device, a rotating shaft, and fan blades. The driving device is located on the rear side of the support frame, the rotating shaft is located on the front side of the support frame, the output end of the driving device passes through the support frame and is connected to the rotating shaft, and one end of the rotating shaft is rotatably connected to the fan blades.

[0012] Preferably, a control switch is provided on the front side of the support plate, and the hydraulic cylinder and the drive device are electrically connected to the control switch.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model can fix the bolt during the bolt processing process through the coordinated use of the hydraulic cylinder, the lifting column, the punching head and the fixing mechanism. After the bolt is placed in the positioning hole, the rotating handles on both sides of the workbench are rotated at the same time, the rotating handles drive the threaded rods to rotate, and the threaded rods drive the fixing blocks to move closer to each other, thereby fixing the bolts. After the fixing is completed, the hydraulic cylinder pushes the lifting column down, and the lifting column drives the punching head down, thereby performing cold heading processing on the bolts in the positioning hole, avoiding the phenomenon of bolt deviation during the processing, improving the processing quality, and solving the problem that the bolts are easy to move during the processing.

[0015] 2. The utility model can speed up the production of bolts by adding a cooling mechanism. The driving device drives the rotating shaft to rotate, and the rotating shaft drives the fan blades to rotate, so as to blow air to the bolts, speed up the flow of air, and further speed up the cooling and forming of the bolts. There is no need to cool down by other means such as sprinkling water, which avoids water accumulation on the operating table and ensures the cleanliness of the operating table. At the same time, the production speed of the bolts is improved, and the problem that the bolts cannot be cooled quickly and the production speed is slow is solved.

[0016] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
