Description

Technical Field

[0001] This utility model relates to the field of punch press blanking and collection technology, and in particular to a punch press blanking auxiliary mechanism. Background Technology

[0002] A punch press is a mechanical device that uses vertical pressure to form, punch, bend, and process metal or non-metal materials. The punch press is the pressure execution platform, and the mold is the process implementation tool. The two need to be used together.

[0003] Furthermore, some large punch presses, when used with progressive dies, can achieve progressive stamping. Progressive stamping is an efficient and continuous metal sheet processing technology. Through multi-station progressive dies, the punching, forming, bending and other processes are completed step by step on the punch press, and finally complete parts are produced.

[0004] When a punch press is used in conjunction with progressive dies for multi-station progressive stamping, some waste material will be generated at multiple stations. If the waste material cannot be transported to the outside of the punch press in time, the waste material generated during the stamping process will fall onto the lower table of the punch press. When the waste material accumulates to a certain extent on the lower table, the machine needs to be stopped to clean up the waste material, which reduces the production efficiency of the punch press. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a punch press blanking auxiliary mechanism to solve the problem that when existing punch presses are used in conjunction with progressive dies for progressive stamping production, the waste generated cannot be transported to the outside of the punch press in a timely manner, and the waste will continue to accumulate on the lower table. When the waste accumulates to a certain extent, the machine needs to be stopped for cleaning, which reduces the production efficiency of the punch press.

[0006] To achieve the above objectives, this utility model provides a punch press blanking auxiliary mechanism, including a lower table, a progressive die body mounted on the lower table, and a plurality of receiving grooves on the progressive die body, and a receiving hopper inclinedly disposed in the receiving grooves. A support rod is mounted on one side of the progressive die body via a support, and the support rod contacts the bottom of the receiving hopper.

[0007] It also includes a support frame bolted to the press bed, on which a swing arm assembly is rotatably connected. The swing arm assembly is connected to the receiving hopper, and a drive assembly for driving the swing arm assembly to swing is fixedly connected to the top of the support frame. When the drive assembly drives the swing arm assembly to swing, the swing arm assembly can push the receiving hopper to slide on the support rod, so that the receiving hopper can extend into or out of the receiving slot.

[0008] Preferably, the swing arm assembly includes a swing arm rotatably connected to a support frame via a pin, and a swing rod is movably connected to the bottom end of the swing arm. A movable part connected to the receiving hopper is slidably sleeved on the swing rod.

[0009] Preferably, the swing arm has a through hole, and the end of the swing rod is rotatably connected in the through hole.

[0010] Preferably, the movable part includes a movable sleeve that is slidably sleeved on the swing rod, and a mounting base is fixedly connected to the movable sleeve, the mounting base being connected to the receiving hopper.

[0011] Preferably, the movable sleeve is provided with a locking bolt, and the movable sleeve has a threaded hole adapted to the locking bolt, and the end of the locking bolt abuts against the swing rod.

[0012] Preferably, the drive assembly includes a housing fixedly connected to the top of the support frame, and the bottom of the housing has a slot for the top of the swing arm to pass into the housing. A cylinder is hinged inside the housing, and the output end of the cylinder is hinged to the top of the swing arm.

[0013] The beneficial effects of this utility model are as follows: The punch press blanking auxiliary mechanism provided by this utility model can push the receiving hopper to slide on the support rod when the punch press and progressive die are used to perform progressive stamping on the workpiece. When the progressive die body is closed, the swing arm assembly can push the receiving hopper to slide on the support rod by swinging clockwise, so that the receiving hopper moves into the receiving groove, thereby allowing the waste generated by stamping the workpiece to fall onto the receiving hopper, avoiding the waste from falling directly onto the lower table.

[0014] When the progressive die body completes the mold closing action and the mold is separated, the counterclockwise swing of the swing arm assembly can push the receiving hopper to slide on the support rod, causing the receiving hopper to move out of the receiving groove, completing one action. Because the receiving hopper is tilted and there will be some vibration during the movement of the receiving hopper, it is convenient for the waste material received in the receiving hopper to be transported to the outside of the punch press. This enables the punch press to transport the generated waste material to the outside in a timely manner during production, reducing downtime and improving work efficiency.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a punch press blanking auxiliary mechanism includes a lower table 1, a progressive die body 2 mounted on the lower table 1, and a plurality of receiving grooves 3 on the progressive die body 2. It also includes a receiving hopper 8 inclinedly arranged in the receiving grooves 3. A support rod 4 is mounted on one side of the progressive die body 2 through a support, and the support rod 4 contacts the bottom of the receiving hopper 8.

[0025] It also includes a support frame 5 bolted to the press bed (not shown in the figure), a swing arm assembly 6 rotatably connected to the support frame 5, the swing arm assembly 6 being connected to the receiving hopper 8, and a drive assembly 7 for driving the swing arm assembly 6 to swing is fixedly connected to the top of the support frame 5. When the drive assembly 7 drives the swing arm assembly 6 to swing, the swing arm assembly 6 can push the receiving hopper 8 to slide on the support rod 4, so that the receiving hopper 8 can extend into or out of the receiving groove 3.

[0026] In a preferred embodiment of the present invention, the swing arm assembly 6 includes a swing arm 61 rotatably connected to the support frame 5 via a pin. A swing rod 62 is movably connected to the bottom end of the swing arm 61. A through hole is provided on the swing arm 61. The end of the swing rod 62 is rotatably connected to the through hole. A movable part connected to the receiving hopper 8 is slidably sleeved on the swing rod 62.

[0027] When the punch press, in conjunction with the progressive die body 2, performs progressive stamping on the workpiece, and the punch press drives the progressive die body 2 to close the die, refer to [reference needed]. Figure 5 The drive assembly 7 pushes the swing arm 61 to swing clockwise around the pin. Since the swing rod 62 is rotatably connected to the swing arm 61, the swing arm 61 can always push the receiving hopper 8 to move on the support rod 4 during the swinging process. The support rod 4 can always support the receiving hopper 8, making the receiving hopper 8 move more smoothly and steadily into the receiving groove 3. This allows the waste generated by stamping the workpiece to fall onto the receiving hopper 8, preventing the waste from falling directly onto the lower table 1.

[0028] When the progressive die body 2 completes its mold closing action and then proceeds with mold separation, refer to... Figure 4 The drive assembly 7 pushes the swing arm 61 to swing counterclockwise around the pin shaft. The swing arm 61 drives the swing rod 62 to swing, so that the swing rod 62 can move the receiving hopper 8 to the outside of the receiving groove 3. When it moves to the initial position of the receiving hopper 8 before the mold is closed, one action is completed. Since the receiving hopper 8 is tilted and there will be a certain vibration during the movement of the receiving hopper 8, the waste in the receiving hopper 8 can fall to the outside of the lower table 1 when the receiving hopper 8 moves to the outside of the receiving groove 3. This makes it easy for the waste in the receiving hopper 8 to be transported to the outside of the punch press. This realizes that the punch press can transport the generated waste to the outside in a timely manner during production, reduce downtime and improve work efficiency.

[0029] In another preferred embodiment of the present invention, the movable part includes a movable sleeve 63 that is slidably sleeved on the swing rod 62, and a mounting base 64 is fixedly connected to the movable sleeve 63. The mounting base 64 is connected to the receiving hopper 8.

[0030] The movable sleeve 63 is provided with a locking bolt 65, and the movable sleeve 63 is provided with a threaded hole that matches the locking bolt 65. The end of the locking bolt 65 abuts against the swing rod 62.

[0031] The position of the receiving hopper 8 can be adjusted by adjusting the position of the movable sleeve 63, ensuring that the receiving hopper 8 is located in the receiving groove 3 to receive the waste that falls off during the stamping of the workpiece.

[0032] When it is necessary to change the position of the receiving hopper 8, loosen the locking bolt 65 to release the limiting fixation of the moving sleeve 63 and the receiving hopper 8, then move the receiving hopper 8 so that the moving sleeve 63 can slide on the swing rod 62. After moving to the appropriate position, tighten the locking bolt 65.

[0033] In another embodiment of the present invention, the drive assembly 7 includes a housing 71 fixedly connected to the top of the support frame 5, and the bottom of the housing 71 is provided with a slot for the top of the swing arm 61 to pass into the housing 71. A cylinder 72 is hinged inside the housing 71, and the output end of the cylinder 72 is hinged to the top of the swing arm 61.

[0034] When it is necessary to drive the swing arm 61 to swing clockwise or counterclockwise, the swing arm 61 can be driven to swing around the pin shaft by controlling the extension and retraction of the output end of the cylinder 72.

[0035] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0036] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
