[0026] In the related art, the hull is composed of a large number of structures. Among them, the bulb flat steel is one of the most used profiles. Most ship types require thousands of bulb flat steels of different specifications and length dimensions. Due to the complex design of the hull structure, the bulb flat steel needs to be cut and blanked according to the drawings, including marking, cutting allowance, and opening flow holes, R holes, grooves, etc. At present, major domestic shipyards still rely heavily on manual blanking for bulb flat steel. Since the thickness of the bulb head of the bulb flat steel itself is relatively thick and it is an irregular shape, it cannot maintain a horizontal state on the profile cutting platform, resulting in inconvenient operation for construction workers, affecting the cutting quality, and it is difficult to guarantee the blanking accuracy.
[0027] To solve this problem, an embodiment of the present utility model provides a blanking tooling, which can improve the blanking efficiency of the bulb flat steel 300, and can ensure the temporary stable horizontal fixation of the bulb flat steel 300 during blanking, ensuring the stability during the blanking scribing and cutting processes, thereby significantly improving the cutting accuracy and quality. The specific structure and functions of the blanking tooling provided by the embodiment of the present utility model will be further described below in combination with the text and drawings.
[0028] Referring to Figure 1 and Figure 2 , according to the blanking tooling provided by some embodiments of the present utility model, which is applied to the blanking of the bulb flat steel 300. The bulb flat steel 300 includes a web 310 and a bulb head 320. The bulb head 320 is located on one side of the web 310. The blanking tooling includes: a handle 100 and a clamping member 200. The handle 100 includes a cross bar 110 and a gripper 120. The cross bar 110 is arranged in a horizontal direction and the lower end surface is a plane. The gripper 120 is arranged above the cross bar 110. The gripper 120 and the cross bar 110 define a gripper 120 groove through which a worker's palm can pass; the clamping member 200 includes a connecting rod 210 and a clamping rod 220. The connecting rod 210 is arranged in a vertical direction. The upper end of the connecting rod 210 is connected to the middle part of the cross bar 110 and is located below the cross bar 110. The clamping rod 220 is connected to the lower end of the connecting rod 210 and is arranged in a horizontal direction. An opening-facing clamping groove 230 is formed between the upper end surface of the clamping rod 220 and the lower end surface of the cross bar 110; wherein, the web 310 can be clamped into the clamping groove 230. Along the vertical direction, the width of the connecting rod 210 is the same as the width of the bulb head 320.
[0029] According to the blanking tooling provided by some embodiments of the present utility model, this tooling is designed specifically to improve the efficiency and quality of the blanking operation of the bulb flat steel 300. After the web 310 of the bulb flat steel 300 is clamped into the clamping groove 230, since the height of the clamping rod 220 of the clamping member 200 is the same as the height of the bulb head 320 of the bulb flat steel 300, it can ensure the temporary stable horizontal fixation of the bulb flat steel 300, ensuring the stability during the blanking scribing and cutting processes, thereby significantly improving the cutting accuracy and quality. The upper end of the handle 100 is equipped with a gripper 120, and the worker's palm can pass through the gripper 120 groove to hold the gripper 120 tightly, which is convenient for the worker to operate and is beneficial to improving work efficiency. In addition, with its simple structure, light and flexible characteristics, this tooling is not only applicable to the blanking assistance of various bulb flat steels 300 in shipbuilding, but also can be widely used in the processing of similar products in the steel structure industry, effectively improving the working environment, reducing the manual labor intensity, and at the same time greatly improving the work efficiency and economic benefits. It is an indispensable practical tool in the industry.
[0030] Referring to Figure 1 and Figure 2, according to the blanking tooling provided by some embodiments of the present utility model, a guiding inclined surface 140 is provided at one end of the cross bar 110 close to the opening of the clamping groove 230. When the tooling is clamped into the bulb flat bar 300, the guiding inclined surface 140 at the end of the cross bar 110 can guide the web 310 into the clamping groove 230, and can prevent the phenomenon that the end of the cross bar 110 gets stuck with the bulb flat bar 300, resulting in the bulb flat bar 300 being unable to enter the clamping groove 230.
[0031] Refer to Figure 3 , it can be understood that the lower end surface of the cross bar 110 is a horizontal plane as a whole. When multiple bulb flat bars 300 are arranged side by side, one side of the cross bar 110 clamps one bulb flat bar 300, and the other side abuts against the upper part of the adjacent bulb flat bar 300, which is beneficial to ensuring the horizontality of the whole multiple bulb flat bars 300.
[0032] Refer to Figure 1 and Figure 2 , according to the blanking tooling provided by some embodiments of the present utility model, a pointed head part 240 is provided at one end of the clamping rod 220 close to the opening of the clamping groove 230, and an inclined surface is provided on the lower side of the pointed head part 240; during use, the pointed head part 240 first inserts under the bulb flat bar 300, and then the worker pushes the tooling. Under the guidance of the pointed head part 240, the clamping rod 220 can move to the lower side of the web 310, so that the web 310 entering the bulb flat bar 300 can enter the clamping groove 230.
[0033] Refer to Figure 1 and Figure 2 , according to the blanking tooling provided by some embodiments of the present utility model, the gripper 120 is semicircular, and the gripper 120 and the cross bar 110 define a semicircular gripper 120 groove. The semicircular gripper 120 is not easy to bruise the worker, which is beneficial to improving safety.
[0034] Refer to Figure 1 and Figure 2 , according to the blanking tooling provided by some embodiments of the present utility model, the gripper 120 is fixed above the cross bar 110 by welding, and the fixing method of the gripper 120 and the cross bar 110 is simple and reliable.
[0035] Refer to Figure 1 and Figure 2 , according to the blanking tooling provided by some embodiments of the present utility model, the upper end of the connecting rod 210 is fixed to the cross bar 110 by welding, and the fixing method of the connecting rod 210 and the cross bar 110 is simple and reliable.
[0036] It can be understood that the clamping rod 220 is fixed to the lower end of the connecting rod 210 by welding; in addition, the connecting rod 210 and the clamping rod 220 can be an integrally formed structure and can be formed by stamping.
[0037] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the relevant art, various changes can be made without departing from the gist of the present utility model.
