Description

Technical Field

[0001] The utility model relates to the technical field of die-casting part processing, in particular to a full-automatic die-casting part waste cutting press. Background Technique

[0002] A die-casting part is a part produced by die casting. It uses a die-casting machine, which is a die-casting machine equipped with a die-casting mold for casting parts. Molten metals such as copper, zinc, aluminum, or aluminum alloy, which are heated to a liquid state, are poured into the feeding port of the die-casting machine. After being die-cast by the die-casting machine, copper, zinc, aluminum parts, or aluminum alloy parts with shapes and sizes restricted by the mold are cast. Such parts are usually called die-casting parts. Due to the characteristics of the die-casting process, the die-casting parts produced usually have gate runners and exhaust waste packages, which need to be removed after die-casting to avoid affecting the use of the die-casting parts.

[0003] Existing die-casting part waste removal equipment usually uses cutters or pressing rods to remove waste, but it is difficult to automatically complete the work of effectively cleaning the gate runner and exhaust waste package and then classifying and collecting the removed waste and finished products. This makes it difficult for the overall removal process and the collection work of waste and finished products to be synchronized and coordinated, resulting in low efficiency. In addition, the pressing structure used for stamping and removing waste usually has poor adjustability and is difficult to adjust the working range of the pressing structure according to the product size and the form of waste, so its applicability is not good. Therefore, in view of the above problems, a full-automatic die-casting part waste cutting press is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a full-automatic die-casting part waste cutting press. This die-casting part processing can move the die-casting part to be processed through a grasping robotic arm to change the working station for waste removal process. First, the end exhaust waste on the side is removed by stamping at the exhaust waste package removal station, and it falls separately and is collected. Then, the product finished product on the outside is removed by stamping at the finished product punching station, and it falls separately and is collected. Finally, the remaining gate runner waste is driven by the grasping robotic arm to move backward and fall and be collected. In this way, a complete set of waste removal processes, including automatically completing waste removal, collection, and finished product collection, is realized, with high working efficiency. At the same time, the position and quantity of the pressing rods connected by threads on the mounting plate can be changed, so that effective stamping and removal can be achieved for waste of different sizes or forms, greatly improving the overall applicable range of the machine. This solves the technical problems in the prior art that the synchronization and coordination between the entire removal process and the collection work of waste and finished products are poor, it is difficult to be fully automatic, and the pressing structure used for stamping and removing waste usually has poor adjustability.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problems is as follows:

[0006] A fully automatic waste cutting press for die-castings, comprising a workbench, on which a processing table board is installed, and an upper cover is provided over the processing table board. There is a rotary loading platform for positioning and placing die-castings to be processed, an exhaust waste package removal station and a finished product punching station, both of which are installed on the upper cover. There is a grasping robotic arm for grasping and moving the die-castings to be processed to change stations. Among them, the structural compositions and working methods of the exhaust waste package removal station and the finished product punching station are exactly the same. The exhaust waste package removal station includes a working cylinder with an adjustable punching head installed on the output shaft. The adjustable punching head includes a mounting plate with a number of threaded holes, and some of the threaded holes are threadedly connected with pressing rods.

[0007] With the above structural form, the grasping robotic arm moves the die-castings to be processed to change stations for the waste removal process. First, the exhaust waste package removal station punches and removes the end exhaust waste on the side, making it fall separately and be collected. Subsequently, the finished product punching station punches and removes the product finished products on the outside, making them fall separately and be collected. Finally, the grasping robotic arm drives the remaining gate runner waste to move backward, making it fall and be collected. In this way, a complete waste removal process of automatically completing waste clearance, collection and finished product collection is realized, with high working efficiency. In addition, the position and quantity of the pressing rods threadedly connected to the mounting plate can be changed, enabling effective punching and removal of waste of different sizes or forms, greatly improving the overall applicable range of the machine.

[0008] In a possible implementation manner, the die-castings to be processed include gate runner waste in the middle, with product finished products connected to both sides of the gate runner waste, and end exhaust waste connected to the outer ends of the product finished products.

[0009] The above structural form is the composition form of most die-castings. Among them, the gate runner waste is the section before the molten metal enters the gate and reaches the product mold, and the end exhaust waste is formed due to the exhaust phenomenon at the other end of the product mold after the molten metal is poured in.

[0010] In a possible implementation manner, the exhaust waste package removal station is used to press down the end exhaust waste, and the finished product punching station is used to press down the product finished products.

[0011] With the above structural form, the mutual separation of the product finished products, end exhaust waste and gate runner waste can be completed in combination, and since the mutual separation is not carried out at the same position, it is also convenient for the collection of the above three.

[0012] In a possible implementation manner, the exhaust waste package removal station further includes a fixing cylinder, and the output shaft of the fixing cylinder is fixedly connected with a downward pressing fixing head for pressing and fixing the end of the gate runner waste.

[0013] With the above structural form, it is possible to fix the whole die-casting to be processed by using the cylinder to drive the pressing head to press down and clamp the gate runner waste, preventing it from sliding when being pressed and ensuring the normal progress of the work of removing waste or taking finished products.

[0014] In a possible implementation, three blanking ports are arranged on the processing platen from front to back, where the first two blanking ports are respectively located directly below the exhaust waste removal station and the finished product punching station.

[0015] With the above structural form, the first blanking port completes the blanking and collection work of the end exhaust waste, the second blanking port completes the blanking and collection work of the product finished product, and the third blanking port completes the blanking and collection work of the gate runner waste.

[0016] In a possible implementation, a first support member is fixedly arranged on the first blanking port, and a second support member is fixedly arranged on the second blanking port. Both are used to support the die-casting to be processed. Among them, the first support member includes two symmetrically arranged support bars, and the second support member includes a support bar arranged in the middle of the blanking port.

[0017] With the above structural form, it can play a supporting role in the die-casting to be processed. When removing the end exhaust waste, the first support member can support both sides of the end exhaust waste, facilitating the removal of the end exhaust waste. When pressing the finished product, the second support member is used to support the gate runner waste in the middle, facilitating the pressing of the finished product.

[0018] In a possible implementation, a waste package collection port, a finished product collection port, and a gate runner collection port are fixedly arranged on the lower side of the three blanking ports in sequence from front to back.

[0019] With the above structural form, it can respectively complete the collection work of the end exhaust waste, the finished product, and the gate runner waste, and introduce the three into their respective storage containers respectively to achieve fully automatic classification collection.

[0020] In a possible implementation, four guide rods are fixedly arranged on the upper end surface of the adjustable punching head, and the guide rods pass through the upper cover and are in sliding contact with it.

[0021] With the above structural form, the guide rods can play a restraining role, avoiding the deflection of the adjustable punching head during the up and down movement operation, which may cause the punching position of the pressure rod to shift and lead to the failure of the operation of removing waste or taking finished products.

[0022] In summary, the present utility model has the following beneficial technical effects:

[0023] The waste removal process is carried out by moving the die casting to be processed through a robotic arm to change the working station. First, the exhaust waste package removal station punches and removes the end exhaust waste on the side, causing it to fall separately and be collected. Subsequently, the finished product punching station punches and removes the finished product on the outside, causing it to fall separately and be collected. Finally, the robotic arm drives the remaining gate runner waste to move backward, causing it to fall and be collected. In this way, a complete waste removal process of automatically completing waste removal, collection, and finished product collection is achieved, with high working efficiency.

[0024] In addition, the position and quantity of the pressure rod connected by threads on the mounting plate can be changed, enabling effective punching and removal of waste of different sizes or forms, greatly improving the overall applicability of the machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0034] As Figure 1 - Figure 2 As shown in the figure, a fully automatic waste cutting press for die-cast parts provided in this embodiment includes a workbench 1, on which a processing table board 11 is installed, and an upper cover 12 is covered on the processing table board 11. There is a rotary loading platform 5 for positioning and placing the die-cast parts 6 to be processed, an exhaust waste package removal station 2 and a finished product punching station 3, both of which are installed on the upper cover 12, and a grasping robotic arm 4 for grasping and moving the die-cast parts 6 to be processed to change stations. Through the above structural form, the waste removal process is carried out by moving the die-cast parts 6 to be processed by the grasping robotic arm 4 to change stations. First, the end exhaust waste 63 on the side is punched and removed by the exhaust waste package removal station 2, so that it falls separately and is collected. Subsequently, the product finished product 62 on the outside is punched and removed by the finished product punching station 3, so that it falls separately and is collected. Finally, the remaining gate runner waste 61 is driven by the grasping robotic arm 4 to move backward, so that it falls and is collected. In this way, a complete waste removal process of automatically completing waste removal, collection and finished product collection is realized, with high working efficiency.

[0035] As Figure 3 - Figure 4 As shown in the figure, the structural composition and working mode of the exhaust waste package removal station 2 and the finished product punching station 3 are exactly the same. The exhaust waste package removal station 2 includes a working cylinder 21 with an adjustable punching head 23 installed on the output shaft. The adjustable punching head 23 includes a mounting plate 231 with several threaded holes, and some of the threaded holes are threadedly connected with pressure rods 232. Through the above structural form, the position and quantity of the pressure rods 232 threadedly connected to the mounting plate 231 can be changed, so that effective punching and removal effects can be achieved on waste materials of different sizes or forms, greatly improving the overall applicable range of the machine.

[0036] In addition, the exhaust waste package removal station 2 further includes a fixing cylinder 22, and the output shaft of the fixing cylinder 22 is fixedly connected with a downward pressing fixing head 24, which is used to press and fix the end of the gate runner waste 61. Through the above structural form, the whole die-cast part 6 to be processed can be fixed by driving the downward pressing fixing head 24 to press down and fix the gate runner waste 61 by the working of the fixing cylinder 22, preventing it from sliding when being pressed, resulting in the inability to carry out the waste removal or finished product taking work normally.

[0037] Particularly, four guide rods 25 are fixedly arranged on the upper end surface of the adjustable punching head 23, and the guide rods 25 pass through the upper cover 12 and are in sliding contact with it. Through the above structural form, the guide rods 25 can play a restraining role, avoiding the adjustable punching head 23 from deflecting during the up and down movement operation, resulting in the deviation of the punching position of the pressure rod 232 and the failure of the waste removal or finished product taking operation.

[0038] As Figure 5 shown, the die-casting part 6 to be processed includes a gate runner waste 61 in the middle, with product finished parts 62 connected to both sides of the gate runner waste 61, and end exhaust waste 63 connected to the outer ends of the product finished parts 62. The above structural form is the composition form of most die-casting parts. Among them, the gate runner waste 61 is the section of the molten metal after entering the gate and before reaching the product mold, and the end exhaust waste 63 is formed due to the exhaust phenomenon at the other end of the product mold after the molten metal is poured in.

[0039] Among them, the exhaust waste removal station 2 is used to press down the end exhaust waste 63, and the finished product punching station 3 is used to press down the product finished parts 62. Through the above structural form, the mutual separation of the product finished parts 62, the end exhaust waste 63, and the gate runner waste 61 can be completed in combination. And because the mutual separation is not carried out at the same position, it is also convenient for the collection of the above three.

[0040] As Figure 2 、 Figure 6 shown, three blanking openings 111 are arranged on the processing platen 11 from front to back. Among them, the first two blanking openings 111 are respectively located directly below the exhaust waste removal station 2 and the finished product punching station 3. Through the above structural form, the blanking collection of the end exhaust waste 63 is completed by the first blanking opening 111, the blanking collection of the product finished parts 62 is completed by the second blanking opening 111, and the blanking collection of the gate runner waste 61 is completed by the third blanking opening 111.

[0041] In addition, a waste package collection port 71, a finished product collection port 72, and a gate runner collection port 73 are fixedly arranged in sequence from front to back below the three blanking openings 111. Through the above structural form, the collection of the end exhaust waste 63, the product finished parts 62, and the gate runner waste 61 can be completed respectively, and the three are respectively introduced into their respective storage containers to realize fully automatic classification collection.

[0042] As Figure 6 shown, a first support member 131 is fixedly arranged on the first blanking opening 111, and a second support member 132 is fixedly arranged on the second blanking opening 111. Both of the above are used to support the die-casting part 6 to be processed. Among them, the first support member 131 includes two symmetrically arranged support bars, and the second support member 132 includes a support bar arranged in the middle of the blanking opening 111. Through the above structural form, it can play a supporting role for the die-casting part 6 to be processed during processing. Among them, when removing the end exhaust waste 63, the first support member 131 can support both sides of the end exhaust waste 63 to facilitate the removal of the end exhaust waste 63. When pressing the product finished parts 62, the second support member 132 is used to support the gate runner waste 61 in the middle to facilitate pressing down the product finished parts 62.

[0043] The working principle and process of the present utility model are as follows:

[0044] The robotic arm 4 moves the die casting 6 to be processed to change the working station for waste removal process. First, the exhaust waste package removal station 2 punches and removes the end exhaust waste 63 on the side, making it fall separately and be collected. Subsequently, the finished product punching station 3 punches and removes the outer product finished product 62, making it fall separately and be collected. Finally, the robotic arm 4 drives the remaining gate runner waste 61 to move backward, making it fall and be collected. In this way, a complete waste removal process of automatic waste removal, collection, and finished product collection is achieved, with high working efficiency.

[0045] Among them, the structural composition and working mode of the exhaust waste package removal station 2 and the finished product punching station 3 are exactly the same. During processing, both use the method of the fixing cylinder 22 working to drive the pressing fixed head 24 to press down and clamp the gate runner waste 61 to play a role in fixing the whole die casting 6 to be processed. Subsequently, the working cylinder 21 works to drive the adjustable punching head 23 to press down, so that the pressure rod 232 on it contacts the points on the die casting 6 to be processed, playing a role in removing waste or pressing the finished product.

[0046] Moreover, during use, the position and quantity of the pressure rod 232 threadedly connected to the mounting plate 231 can be freely changed, so that effective punching and removal can be achieved for waste of different sizes or forms, greatly improving the overall application range of the machine.

[0047] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
