Description

Technical Field

[0001] This utility model relates to the field of connecting rod manufacturing technology, specifically a precision edge-cutting mold for connecting rod forgings. Background Technology

[0002] For example, a precision trimming die for connecting rod forgings, as disclosed in patent publication number CN216461478U, includes a fixed base, a lower die base fixedly mounted on the fixed base, a lower die inside the lower die base, a top plate fixedly connected to the fixed base via a support rod, a hydraulic cylinder fixedly mounted on the top plate, a lifting plate fixedly mounted at the bottom of the hydraulic cylinder, an upper die base fixedly mounted at the bottom of the lifting plate, and a lower die fixedly mounted at the bottom of the upper die base. Scrap boxes are fixedly mounted on both sides of the fixed base. During trimming, the lower die can move downwards to remove the scrap from the edge of the connecting rod forging using a trimming blade, ensuring that the scrap does not stick to the connecting rod forging and improving the trimming effect. Simultaneously, after trimming, the lower die rises, making it easier to remove the trimmed connecting rod forging, thus making operation more convenient. The removed scrap falls onto the lower die base and automatically slides into the scrap box via an inclined edge, increasing its practicality.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal cutting blade, the spatter that may be generated during the cutting process, such as metal shavings and cutting waste, can easily cause injury to the operator. Therefore, in order to address this issue, we propose a more convenient and practical precision cutting die for connecting rod forgings to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a precision cutting die for connecting rod forgings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision trimming mold for connecting rod forgings, comprising a trimming mechanism and a protective mechanism for cutting connecting rod forgings. The protective mechanism includes a base plate, with slide rails fixedly connected to both sides of the top of the base plate, a connecting plate provided on one side of the top of the base plate, a handle fixedly connected to one side of the connecting plate, protective plates provided on both sides of the connecting plate, and several equidistant through holes opened on both sides of the protective plates, with pins threaded into the through holes, and one end of the pin threadedly connected to the connecting plate.

[0006] Furthermore, the cutting mechanism includes a base, which is connected to a bottom plate. Connecting rods are fixedly connected to the four corners of the top of the base, and a top plate is fixedly connected to one end of each connecting rod.

[0007] Furthermore, a hydraulic cylinder is installed at the center of the top of the top plate, and a sliding plate is fixedly connected to the output end of the hydraulic cylinder. The sliding plate and the connecting rod are slidably connected. An upper mold is fixedly connected to the bottom of the sliding plate, and a cutting blade is installed at the bottom of the upper mold.

[0008] Furthermore, a lower mold is fixedly connected to the top center of the base, and a cutting groove is provided on the top of the lower mold, which is compatible with the cutting blade.

[0009] Furthermore, an observation window is provided on one side of the protective plate, and a slot is provided on the inner wall of the top side of the protective plate, into which a connector plate is inserted.

[0010] Furthermore, the bottom sides of the protective plate are rotatably connected with several equally spaced pulleys, which are matched with the slide rails.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This precision trimming die for connecting rod forgings, through its trimming and protective mechanisms, allows for precise edge trimming. Before trimming, the connecting plate and protective plate are manually connected by rotating a pin. Then, the handle is manually pushed, and the protective plate moves along the base plate with the help of pulleys and slide rails until it completely covers the trimming mechanism. A connecting plate is then inserted into the protective plate through a slot, completing the protective operation. Finally, the working status of the trimming mechanism can be observed in real time through an observation window. This device effectively blocks flying debris, such as metal shavings and trimming waste, from the trimming process, preventing injury to operators. It is highly practical and suitable for widespread adoption.

[0013] Meanwhile, the trimming mechanism enables the trimming blade to accurately cut into the trimming groove, precisely trimming the connecting rod forging, ensuring the accuracy and consistency of the trimming dimensions, and improving the overall quality of the connecting rod forging.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the processing of automotive parts, edge trimming equipment is required. The edge trimming equipment provided by this utility model is specifically used for edge trimming of connecting rod forgings in the automotive parts processing process. During the edge trimming operation, it is necessary to closely observe the operation of the equipment, including whether the movement of the hydraulic cylinder 104 is normal, the wear of the edge trimming blade 109, etc. Regularly clean the metal debris and oil stains in the edge trimming blade 109 and the edge trimming groove 107, keep the mold clean, prevent the edge trimming blade 109 from wearing out and affecting the edge trimming accuracy, and regularly check whether the observation window 207 is damaged or loose, and ensure that the transparency and sealing of the observation window 207 are good so that the operator can clearly observe the edge trimming situation.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a precision trimming mold for connecting rod forgings, including a trimming mechanism 1 for cutting connecting rod forgings and a protective mechanism 2. The protective mechanism 2 includes a base plate 201, slide rails 202 are fixedly connected to both sides of the top of the base plate 201, a connecting plate 203 is provided on one side of the top of the base plate 201, a handle 204 is fixedly connected to one side of the connecting plate 203, protective plates 205 are provided on both sides of the connecting plate 203, and several equidistant through holes are opened on both sides of the protective plate 205. A pin 206 is threadedly connected to the through holes, and one end of the pin 206 is threadedly connected to the connecting plate 203.

[0021] like Figure 2As shown, the trimming mechanism 1 includes a base 101, which is connected to a base plate 201. Connecting rods 102 are fixedly connected to the four corners of the top of the base 101. A top plate 103 is fixedly connected to one end of the connecting rods 102. A hydraulic cylinder 104 is installed at the center of the top of the top plate 103. A sliding plate 105 is fixedly connected to the output end of the hydraulic cylinder 104. The sliding plate 105 and the connecting rods 102 are slidably connected. An upper mold 108 is fixedly connected to the bottom of the sliding plate 105. A trimming blade 109 is installed at the bottom of the upper mold 108. A lower mold 106 is fixedly connected to the center of the top of the base 101. A trimming groove 107 is opened on the top of the lower mold 106. The trimming groove 107 and the trimming blade 109 are compatible with each other.

[0022] It should be noted that during use, the connecting rod forging is first placed in the lower mold 106. Then, the hydraulic cylinder 104 is activated, pushing the sliding plate 105 downward along the connecting rod 102. This causes the upper mold 108 and the trimming blade 109 to be precisely inserted into the trimming groove 107 of the lower mold 106. With the cooperation of the trimming blade 109 and the trimming groove 107, the connecting rod forging is cut, achieving precise trimming. After trimming, the hydraulic cylinder 104 drives the sliding plate 105 and the upper mold 108 to return to their original positions, completing one trimming action. The trimming mechanism 1 enables the trimming blade 109 to accurately cut into the trimming groove 107, precisely trimming the connecting rod forging, ensuring the accuracy and consistency of the trimming dimensions, and improving the overall quality of the connecting rod forging.

[0023] like Figure 3 As shown, an observation window 207 is provided on one side of the protective plate 205, and a slot is provided on the inner wall of one side of the top of the protective plate 205. A plug-in plate 208 is inserted into the slot, and several equally spaced pulleys 209 are rotatably connected to both sides of the bottom of the protective plate 205. The pulleys 209 and the slide rail 202 are compatible with each other.

[0024] It should be noted that during use, before the edge trimming operation, first connect the connecting plate 203 and the protective plate 205 by manually rotating the pin 206. Then, manually push the handle 204, and with the cooperation of the pulley 209 and the slide rail 202, the protective plate 205 moves along the base plate 201 until the protective plate 205 completely covers the edge trimming mechanism 1. Then, insert the plug plate 208 into the protective plate 205 through the slot on the protective plate 205 to form a complete protection. Finally, observe the working status of the edge trimming mechanism 1 in real time through the observation window 207. The protective mechanism 2 is easy to operate. Just push the protective plate 205 gently, and the pulley 209 can slide smoothly on the slide rail 202, thereby easily changing the position of the protective plate 205.

[0025] During use, the connecting rod forging is first placed in the lower mold 106, and the handle 204 is manually pushed. With the cooperation of the pulley 209 and the slide rail 202, the protective plate 205 moves along the base plate 201 until the protective plate 205 completely covers the trimming mechanism 1. Then, the insertion plate 208 is inserted into the protective plate 205 through the slot on the protective plate 205 to complete the protection. Next, the hydraulic cylinder 104 is activated, and the hydraulic cylinder 104 pushes the sliding plate 105 downward along the connecting rod 102. This allows the upper mold 108 and the cutting blade 109 to be precisely inserted into the cutting groove 107 of the lower mold 106. With the cooperation of the cutting blade 109 and the cutting groove 107, the connecting rod forging is cut to achieve precise cutting. After the cutting is completed, the hydraulic cylinder 104 drives the sliding plate 105 and the upper mold 108 to return to their original position, completing one cutting action. This device can block the splashes that may be generated during the cutting process, such as metal shavings and cutting waste, to prevent these splashes from causing injury to the operator.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
