Description

Technical Field

[0001] This utility model relates to the field of lock hook forging equipment, and in particular to a lock hook production forging press with protective function. Background Technology

[0002] Locking hooks are used in a variety of scenarios. To ensure the strength of the locking hooks, a hot pressing process is now adopted. First, the rough blank is forged to form a corresponding locking hook model. Then, the corresponding locking hook model is precision machined.

[0003] Existing hot pressing processes often employ hot forging presses, which are industrial equipment that use high temperature and high pressure to form metal. This process requires first heating the metal material to soften it, reduce its resistance to deformation, and increase its plasticity, facilitating subsequent plastic forming. After the heating process is completed, forging is then performed. Currently, heating the metal often involves directly blowing a flame onto the forging die located on the operating table, causing the forging die itself to reach the operating temperature. The flame is directly exposed to the operating table without any protective devices, making it easy for on-site personnel to be burned during material feeding and receiving operations, thus increasing the danger to on-site personnel.

[0033] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0034] like Figures 1-6 As shown, a locking hook production forging press with protective function provided according to an embodiment of the present utility model includes...

[0035] The pressing platform consists of 1000 units, the heating chamber consists of 2000 units, the pressing mold consists of 4000 units, and the pressing assembly consists of 5000 units.

[0036] The heating chamber 2000 is located on top of the pressing platform 1000. The heating chamber 2000 has a heating cavity 2100, and the bottom of the heating cavity 2100 is provided with an installation groove 2110.

[0037] The heating assembly includes multiple igniters 3100 and oxygen injectors 3200. The multiple igniters 3100 are arranged on the outer walls of both sides of the heating chamber 2000, with one end of each igniter 3100 extending into the heating chamber 2100. The oxygen injectors 3200 are located on the top of the heating chamber 2000, above the igniters 3100.

[0038] The oxygen injection component 3200 includes an oxygen injection plate 3210, multiple oxygen injection nozzles 3220, and the oxygen injection component 3200. The oxygen injection plate 3210 is fixedly mounted on the heating chamber 2000. The multiple oxygen injection nozzles 3220 are obliquely mounted through the oxygen injection plate 3210. One end of the oxygen injection nozzle 3220 extends into the heating chamber 2100, and one end of the oxygen injection nozzle 3220 is located directly above one end of the igniter 3100. The other ends of the multiple oxygen injection nozzles 3220 are connected to the oxygen injection pipeline 3230. The oxygen injection pipeline 3230 is located on the top of the oxygen injection plate 3210, and the oxygen injection pipeline 3230 has an air inlet 3231.

[0039] The pressing mold 4000 is set inside the heating cavity 2100. The bottom of the pressing mold 4000 is placed in the mounting groove 2110, and the top of the pressing mold 4000 is provided with a mold groove 4100.

[0040] The pressing assembly 5000 is located above the pressing platform 1000. The pressing assembly 5000 includes a hydraulic cylinder 5100, a fixed plate 5200, multiple guide pillars 5300, a pressing top plate 5400, and a pressing block 5500. The multiple guide pillars 5300 are distributed at the four corners of the pressing platform 1000. The fixed plate 5200 is located at one end of the multiple guide pillars 5300. The hydraulic cylinder 5100 is located on the fixed plate 5200. The output end of the hydraulic cylinder 5100 passes through the fixed plate 5200 and is connected to the top of the pressing top plate 5400. The pressing top plate 5400 slides on the guide pillars 5300. The pressing block 5500 is located at the bottom center of the pressing top plate 5400. The pressing block 5500 cooperates with the mold groove 4100 on the top of the pressing mold 4000.

[0041] When using the protective lock hook forging press of this utility model, the user needs to first raise the pressing assembly 5000 to its highest position, then place the pressing mold 4000 into the heating chamber 2100, ensuring that the bottom of the pressing mold 4000 is located in the mounting groove 2110, thereby positioning the pressing mold 4000. After completing the installation of the pressing mold 4000, install the oxygen spray plate 3210 onto the top of the heating chamber 2000, ensuring that the oxygen spray nozzles 32 on the oxygen spray plate 3210 are in place. Corresponding to igniter 3100, pure oxygen is supplied to oxygen injection component 3200, so that pure oxygen is sprayed out from multiple oxygen injection nozzles 3220. The user then turns on igniter 3100 to generate a flame. At this time, the flame temperature rises under the action of pure oxygen flow. At the same time, the flame is affected by pure oxygen flow and will directly tilt and burn the outer wall of pressing mold 4000, thereby directly heating pressing mold 4000. During this combustion process, the flame is always located inside heating chamber 2000 to avoid contact between the flame and the user.

[0042] Once the pressing mold 4000 reaches the appropriate temperature, the user places the hook blank into the mold groove 4100 of the pressing mold 4000 and controls the pressing component 5000 to move, causing the pressing block 5500 to press against the hook blank, so that the hook blank forms the corresponding hook shape according to the standard in the mold groove 4100. After pressing is completed, the user takes out the pressed hook and puts in the next hook blank to repeat the above pressing process.

[0043] Furthermore, such as Figure 2 and Figure 3 As shown, auxiliary fixing grooves 2120 are provided at both ends of the inner wall of the heating cavity 2100.

[0044] Furthermore, such as Figure 1 As shown, auxiliary sliders 4200 are provided on both sides of the pressing mold 4000, and the pressing mold 4000 is slidably positioned in the heating cavity 2100 via the auxiliary sliders 4200. During installation, after placing the auxiliary sliders 4200 on both sides of the pressing mold 4000 into the auxiliary fixing grooves 2120, the positioning of the pressing mold 4000 can be ensured to be accurate, so that the bottom of the pressing mold 4000 can be placed in the mounting groove 2110.

[0045] Furthermore, such as Figure 5 As shown, the locking hook forging press with protective function also includes a lifting component, which includes a first lifting ring 6100 and a second lifting ring 6200. The first lifting ring 6100 is located at the bottom of the pressing top plate 5400 and on both sides of the pressing block 5500. The second lifting ring 6200 is respectively set on the auxiliary slider 4200, and the first lifting ring 6100 is located directly above the second lifting ring 6200. The pressing mold 4000 is mostly made of metal, making it relatively heavy. During daily installation, users often need to manually pick it up and place it, thus increasing the user's labor intensity. Therefore, the lifting component is used to reduce the labor intensity of personnel.

[0046] The working principle of the lifting component is as follows: When installing the pressing mold 4000, the pressing top plate 5400 is at its lowest point. The user uses multiple chains to connect the first lifting ring 6100 and the second lifting ring 6200 on the same side. After the chains are installed, the user controls the hydraulic cylinder 5100 in the pressing assembly 5000 to raise the pressing top plate 5400, thereby raising the pressing mold 4000. At this time, the user fine-tunes the position of the pressing mold 4000 and controls the pressing top plate 5400 to descend, ensuring that the auxiliary slider 4200 of the pressing mold 4000 slides into the auxiliary fixing groove 2120, thus completing the installation of the pressing mold 4000. When producing different styles of lock hooks, it is necessary to replace the pressing mold 4000. At this time, the pressing mold 4000 is in a high temperature state. The user can fix both ends of the lock chain to the first lifting ring 6100 and the second lifting ring 6200 respectively through remote operation, and raise the pressing top plate 5400 by controlling the hydraulic cylinder 5100 to remove the high temperature pressing mold 4000 from the heating chamber 2100. Then, the user moves the high temperature pressing mold 4000 away from the pressing platform 1000 and uses the same method to install the new pressing mold 4000 into the heating chamber 2100, thereby completing the replacement of the pressing mold 4000.

[0047] Furthermore, such as Figure 2 As shown, the lock hook production forging press with protective function also includes a shock-absorbing support 7000. A shock-absorbing cavity 1100 is opened at the bottom center of the pressing platform 1000, and the shock-absorbing support 7000 is set in the shock-absorbing cavity 1100.

[0048] Furthermore, such as Figure 2 and Figure 6As shown, the shock-absorbing support 7000 includes a shock-absorbing movable rod 7100, a shock-absorbing spring 7200, and a shock-absorbing fixed column 7300. The shock-absorbing fixed column 7300 has a shock-absorbing groove 7310. Multiple shock-absorbing guide grooves 7311 are provided on the inner circumference of the shock-absorbing groove 7310. One end of the shock-absorbing movable rod 7100 extends into the shock-absorbing groove 7310, and multiple shock-absorbing guide blocks 7110 are provided on the outer wall of one end of the shock-absorbing movable rod 7100. The shock-absorbing guide blocks 7110 are slidably disposed in the shock-absorbing guide groove 7311. The other end of the shock-absorbing movable rod 7100 contacts the bottom of the pressing platform 1000. One end of the shock-absorbing spring 7200 is fixed to one end of the shock-absorbing movable rod 7100, and the other end of the shock-absorbing spring 7200 is fixed to the bottom of the shock-absorbing groove 7310. The pressure block 5500 presses against the locking hook blank in the mold groove 4100. This process generates vertical downward stress. In the existing technology, most of the stress can be eliminated by optimizing the mold structure and the reasonable forging structure, but a small amount of stress will still exist, thus affecting the overall service life of the device. At this time, the shock-absorbing support 7000 is set to absorb a small amount of stress, thereby improving the service life of the overall device. The working principle of the shock-absorbing support 7000 is as follows: a small amount of vertical stress is vertically transmitted from the pressing platform 1000 to the shock-absorbing movable rod 7100. The shock-absorbing movable rod 7100 will generate a vertical downward displacement, causing the shock-absorbing movable rod 7100 to compress the shock-absorbing spring 7200. The shock-absorbing spring 7200 will generate a certain deformation, thereby absorbing this part of the downward stress. When the shock-absorbing movable rod 7100 moves downward, due to the cooperation of the shock-absorbing guide groove 7311 and the shock-absorbing guide block 7110, the shock-absorbing movable rod 7100 will not shift left or right, thereby improving the stability of the shock-absorbing movable rod 7100 during the movement.

[0049] Preferably, the inner wall of the heating chamber 2100 is provided with a fireproof layer. The fireproof layer has high temperature resistance, thereby improving the service life of the heating chamber 2000.
