Description
Technical Field
[0001] This utility model relates to the field of stamping technology, and in particular to a stamping die assembly. Background Technology
[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) of the required shape and size. Stamping and forging both belong to plastic processing (or pressure processing) and are collectively called forging and pressing. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. The dies used in stamping are called stamping dies, or simply dies. Dies are special tools for mass-processing materials (metal or non-metal) into the required stamped parts. Dies are crucial in stamping; without dies that meet the requirements, mass stamping production is difficult to carry out; without advanced dies, advanced stamping processes cannot be realized. Stamping processes, dies, stamping equipment, and stamping materials constitute the three elements of stamping processing. Only when they are combined can stamped parts be produced.
[0003] Most existing stamping die assemblies mainly involve fixing the stamping die on a stamping machine, and then moving the upper die downwards via the stamping machine to stamp the sheet metal placed on top of the lower die. However, during the stamping process, the stamping die assembly is prone to damage under high-intensity operation. At the same time, the fixed stamping die is prone to loosening at the connection points after being subjected to vibration, resulting in reduced stability and easy displacement, which can damage the stamped workpiece. Therefore, it is necessary to design a stamping die assembly to solve the above-mentioned problems. Utility Model Content
[0004] The main purpose of this utility model is to provide a stamping die assembly, which aims to solve the problems that stamping dies have poor buffering performance and are easily damaged during high-intensity operation, and poor stability performance and are prone to displacement, resulting in damage to the stamped workpiece.
[0005] To achieve the aforementioned utility model objectives, the first aspect of this utility model proposes a stamping die assembly, including a placement platform; a movable clamping unit, a buffer seat, and a stamping die are provided on the upper part of the placement platform; the movable clamping unit includes two fixed plates, the bottom of which are respectively fixedly connected to the left and right sides of the upper end of the placement platform; a motor is fixedly connected to the front left end of the left fixed plate; a bidirectional lead screw is provided on the front side of the fixed plate; the shaft of the motor is fixedly connected to the left end of the bidirectional lead screw; threaded sleeves are threadedly connected to the left and right sides of the outer side of the bidirectional lead screw; a connecting rod is provided on the rear side of each threaded sleeve; a movable seat is provided on the middle outer side of each connecting rod; side plates are provided on the left and right sides of the upper part of the buffer seat; clamping holes are provided on the bottom of the outer side of each side plate; a first spring is provided on the middle upper end of the buffer seat; the top end of the first spring is located at the middle bottom end of the stamping die.
[0006] Furthermore, a locking groove is provided in the middle of the upper end of the placement platform, and the bottom end of the buffer seat is locked into the inside of the locking groove;
[0007] Furthermore, a guide rod is fixedly connected to the rear side of the fixing plate, and a sliding sleeve is slidably connected to the left and right sides of the outer side of the guide rod. A threaded head is provided at the inner end of both the sliding sleeve and the threaded sleeve, and the two threaded heads are respectively threaded to the front and rear ends of the connecting rod.
[0008] Furthermore, each of the movable seats is provided with a guide pulley at its bottom, and each of the upper left and right sides of the placement platform is provided with a sliding groove, and the guide pulleys are slidably connected to the inner side of the corresponding sliding groove.
[0009] Furthermore, each end of the bidirectional lead screw is provided with a rotating seat, and the rotating seats are respectively fixedly connected to the front part of the inner side of the corresponding fixed plate;
[0010] Furthermore, a first guide sleeve is provided at the middle of the left and right sides of the upper end of the buffer seat, and a second spring is provided inside the first guide sleeve. A fixing groove is provided at the left and right ends of the upper part of the stamping die, and a connecting seat is fixedly connected inside the fixing groove. A second guide post is provided at the bottom of the connecting seat, and the second guide post is slidably connected to the upper inner side of the corresponding first guide sleeve.
[0011] Furthermore, a first mounting groove is provided at the upper center of the buffer seat, and a second mounting groove is provided at the lower center of the stamping die;
[0012] Furthermore, the bottom left and right sides of the stamping die are provided with second guide sleeves, and the middle of the upper left and right sides of the buffer seat are provided with first guide posts, which are slidably connected to the inner side of the corresponding second guide sleeves.
[0013] Furthermore, each of the upper middle parts of the movable base is threaded with a first locking bolt;
[0014] Furthermore, the stamping die is threaded with a second locking bolt at the center of both the left and right sides.
[0015] Beneficial effects:
[0016] This utility model discloses a stamping die assembly. First, a buffer seat is placed in the engagement groove on the upper part of the placement platform. Then, a connecting seat is fixedly connected to the fixing groove using a second locking bolt. Next, the stamping die is placed on top of the buffer seat. A second guide post is placed inside the first guide sleeve, and the second guide sleeve is fitted onto the outside of the first guide post. A first spring is placed between the stamping die and the buffer seat. Then, a motor drives a bidirectional lead screw to rotate, causing the threaded sleeve, connecting rod, moving seat, and sliding sleeve to move from the outside to the inside. The inner end of the moving seat moves to the inside of the clamping hole, securing the buffer seat. Simultaneously, the guide pulley slides inside the sliding groove, and the sliding sleeve rests on the guide rod. The outer side slides, and finally, during the stamping process, when the stamping head presses downward, the stamping die moves downward, causing the second guide post to slide downward inside the first guide sleeve and compress the second spring. The bottom end of the stamping die compresses the first spring, and the second guide sleeve slides outside the first guide post. The first and second springs generate an upward elastic force, which buffers the stamping die. This not only buffers the stamping die downward during the stamping process, preventing damage to the stamping die during high-intensity stamping, but also protects the stamping die. At the same time, the buffer seat supports the stamping die, and the moving clamping unit clamps the buffer seat firmly, preventing the stamped object from deforming and being damaged due to positional movement during the stamping process.
