Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and more specifically to an adjustable stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] For example, patent CN111545640A discloses an adjustable stamping die, including a stamping head, a die assembly, and a driving device. The upper end of the stamping head is connected to the driving device, which drives the stamping head to press down. The stamping head includes 1-N-1 layers of interlocking outer shells. The first layer of the outer shell is located on the outermost layer of the stamping head. Each of the 1-N-1 layers of the outer shell includes a left shell and a right shell. Each left and right shell includes left and right side plates and a horizontal plate connecting the left and right side plates. Multiple locking blocks are provided on the side edges of the left and right side plates of the left shell corresponding to the side edges of the right shell. Multiple locking blocks are provided on the side edges of the left and right side plates of the right shell corresponding to the side edges of the left shell. The device has multiple slots corresponding to the locking blocks. The left and right shells of the first layer are connected by locking blocks and slots, forming an accommodating space between the horizontal plates at both ends and the connected left and right side plates. The width of the horizontal plate of the second layer is shorter than that of the first layer. The left and right side plates of the second layer are locked together in the same way. After locking, the horizontal plates at both ends are locked onto the inner surfaces of the horizontal plates at both ends of the first layer by locking devices. The left and right side plates are locked onto the inner surfaces of the left and right side plates of the first layer by locking devices. The shells of layers 1-N-1 are locked together in sequence, forming an accommodating space inside the N-1 layer. This invention, by setting the shells of the stamping head to lock together, allows the size of the stamping head to be reduced or increased by removing or adding outer shells when adjusting its size; the shape of the stamping head can be changed by removing all shells and placement blocks; and the size and shape of the mold cavity can be changed by using the pushing device and support device at the bottom of the molding device to correspond to the size and shape of the stamping head.

[0004] In actual operation, most stamping dies can only stamp one size of die. When other sizes of devices need to be stamped, a new die has to be made, which reduces work efficiency and increases costs.

[0005] It is evident that the aforementioned problems with existing technologies urgently need to be addressed. Summary of the Invention

[0006] In view of the above-mentioned problems in the prior art, one objective of the present invention is to provide an adjustable stamping die to solve the problems that most stamping dies cannot stamp multi-size devices, resulting in the need to open new dies, which reduces their working efficiency and increases costs.

[0007] To achieve the above objectives, the present invention provides an adjustable stamping die, comprising an upper die assembly, a lower die assembly being snapped into the bottom of the upper die assembly, and freely sliding sliders being symmetrically arranged inside the lower die assembly, with a slot formed between the two sliders. The upper die assembly includes a stamping mechanism and an inclined guide post. The stamping mechanism is driven to maintain an upward vertical movement to increase the exposed end of the inclined guide post so as to snap into the interior of the slider. The inclined guide post is inserted into the interior of the slider to drive the slider to maintain a lateral opposing movement to maintain opening and closing.

[0008] Preferably, the upper mold assembly includes an upper mold shell, an upper mold inner groove is provided inside the upper mold shell, inclined guide posts are symmetrically arranged inside the upper mold inner groove, and a stamping mechanism is provided at the end of the upper mold inner groove near the lower mold assembly.

[0009] Preferably, the stamping mechanism specifically includes a stop block, the inside of which is provided with slots corresponding to each of the inclined guide posts to drive the inclined guide posts to protrude from the outer wall of the upper die shell.

[0010] Preferably, a first groove is provided in the center of one side of the outer wall of the upper mold shell, and a linear array of locking spring pieces are symmetrically arranged inside the first groove. A locking plate is provided on the outer wall of the stop block and engages with the inside of the first groove. Each of the locking spring pieces is assembled to limit the position of the stop block inside the upper mold shell.

[0011] Preferably, a stamping block is provided at the center of the bottom of the stop block, and multiple stamping blocks of successively decreasing size are snapped together inside the stamping block. Each stamping block is provided with a slot to drive the inclined guide post to remain inserted, and each slot is provided with an elastic buckle to drive each stamping block to remain closed.

[0012] The stop block can be restricted to its position inside the upper mold shell by the snap-fit ​​spring clip, thereby limiting the length of the inclined guide post exposed to the outside. This causes the length inserted into the slider to change. Furthermore, as the stop block rises, the inclined guide post is inserted into the slots inside each stamping block, causing the internal elastic buckles to loosen, and in turn, each stamping block protrudes to the outside.

[0013] Preferably, the lower die assembly includes a lower die housing, the lower die housing having a stamping groove inside, and the stamping block being driven and engaged inside the stamping groove.

[0014] Preferably, the stamping groove is provided with a second sliding groove symmetrically on the inner walls of the two sides, and the two sliders are slidably engaged inside the second sliding groove.

[0015] Preferably, the slider has symmetrically formed inclined guide post grooves inside, so as to drive the inclined guide posts to engage inside the slider.

[0016] By varying the length of the inclined guide post, the length of the part locked inside the slider changes, thus driving the slider to slide a distance that changes synchronously. This also changes the length of the slot between the sliders, allowing for the stamping of workpieces of different sizes.

[0017] Beneficial effects: Compared with the prior art, the adjustable stamping die provided by the present invention has the following beneficial effects: 1. The stop block can be restricted to its position inside the upper mold shell by the snap-fit ​​spring, thereby limiting the length of the inclined guide post exposed to the outside. This causes the length inserted into the slider to change. Furthermore, as the stop block rises, the inclined guide post is inserted into the slots inside each stamping block, causing the internal elastic buckles to loosen, and in turn causing each stamping block to protrude to the outside.

[0018] 2. By changing the length of the inclined guide post, the length of the part locked inside the slider changes, thereby driving the slider to slide a distance that changes synchronously and changing the length of the slot between the sliders, thus enabling the stamping of workpieces of different sizes.

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, an adjustable stamping die includes an upper die assembly 1, a lower die assembly 2 is snapped onto the bottom of the upper die assembly 1, and freely sliding sliders 203 are symmetrically arranged inside the lower die assembly 2, forming a slot between the two sliders 203. The upper die assembly 1 includes a stamping mechanism and a slanted guide post 103. The stamping mechanism is driven to maintain an upward vertical movement to drive the exposed end of the slanted guide post 103 to increase and snap onto the inside of the slider 203. The slanted guide post 103 is inserted into the inside of the slider 203 to drive the slider 203 to maintain a lateral opposing movement to maintain opening and closing.

[0024] The main purpose of this adjustable stamping die is to limit the position of the stop 104 within the upper die housing 101 by using the retaining spring 106, thereby limiting the length of the inclined guide post 103 exposed to the outside. This causes a change in the length inserted into the slider 203. Furthermore, by raising the stop 104, the inclined guide post 103 is inserted into the slot 109 inside each stamping block 108, causing the internal elastic buckle 110 to loosen, and causing each stamping block 108 to protrude to the outside in sequence. Also, by changing the length of the inclined guide post 103, the length of the clip inside the slider 203 changes, thereby driving the slider 203 to slide synchronously and changing the length of the slot between the sliders 203, thus enabling the stamping of workpieces of different sizes.

[0025] In the technical solution provided by this invention, by Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that the upper mold assembly 1 includes an upper mold shell 101, and an upper mold inner groove 102 is also provided inside the upper mold shell 101. Inclined guide posts 103 are symmetrically arranged inside the upper mold inner groove 102. A stamping mechanism is also provided at the end of the upper mold inner groove 102 near the lower mold assembly 2. The length of the exposed part of the inclined guide post 103 can be kept changing by the vertical reciprocating motion of the stamping mechanism.

[0026] Furthermore, the stamping mechanism specifically includes a stop block 104, and the interior of the stop block 104 is provided with slots 109 corresponding to each inclined guide post 103, which can drive the inclined guide post 103 to pass through the interior of the stop block 104 and thus expose the exterior of the upper die housing 101, and can be inserted into the interior of the lower die assembly 2.

[0027] Furthermore, a first groove 105 is provided in the center of one side of the outer wall of the upper mold shell 101, and the first groove 105 is symmetrically provided with locking spring pieces 106 arranged in a linear array inside. The outer wall of the stop block 104 is also provided with a locking plate 107 that is engaged with the inside of the first groove 105. The locking plate 107 is fixed to various heights inside the upper mold shell 101 by each locking spring piece 106 in sequence, thereby adjusting the height of the stop block 104 and changing the exposed length of the inclined guide post 103.

[0028] Furthermore, a stamping block 108 is centrally located at the bottom of the stop block 104, and multiple stamping blocks 108 of progressively smaller size are engaged inside each stamping block 108. The stamping blocks 108 can slide and expand and contract. A slot 109 is provided between each stamping block 108 to drive the inclined guide post 103 to be inserted inside and exposed. An elastic buckle 110 is also provided inside the slot 109 between each stamping block 108 to keep the stamping blocks 108 connected. When the inclined guide post 103 is inserted into the slot 109 between the stamping blocks 108, the elastic buckle 110 can be loosened, thereby causing the stamping blocks 108 to unfold sequentially.

[0029] In the technical solution provided by this invention, by Figure 1 , Figure 2 and Figure 3 It is known that the lower mold assembly 2 includes a lower mold housing 201, and the lower mold housing 201 is also provided with a stamping groove 202, which allows the stamping block 108 to be engaged inside for stamping.

[0030] Furthermore, the stamping groove 202 is symmetrically provided with second sliding grooves 204 on both sides of the inner wall, and two sliders 203 are slidably engaged in the interior of the second sliding grooves 204 to change the spacing between the empty grooves, thereby changing the stamping size.

[0031] Furthermore, the slider 203 has symmetrically provided inclined guide post grooves 205 inside, which can drive the inclined guide post 103 to engage inside the slider 203, thereby driving the slider 203 to perform transverse reciprocating motion.

[0032] Working principle: First, by adjusting the position of the clamping plate 107, it is fixed by each clamping spring piece 106, thereby limiting the station height of the stop block 104 inside the upper mold assembly 1, thus changing the length of the inclined guide post 103 exposed to the outside. When the exposed length of the inclined guide post 103 increases, the length inserted into the slider 203 will also increase, thereby increasing the sliding distance of the slider 203 and shortening the distance between the slots between the two sliders 203. Conversely, the distance between the slots between the sliders 203 increases, thus changing the stamping size. When the stop block 104 rises, the inclined guide post 103 extends through the slot 109. When it is inserted into the slot 109 between the two stamping blocks 108, it will activate the internally engaged elastic buckle 110, thereby loosening it and causing the two stamping blocks 108 to slide and unfold, thereby corresponding to the empty slot distance inside the lower die assembly 2 to perform stamping work.

[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
