Description

Technical Field

[0001] This utility model relates to the field of hardware production technology, specifically to a stamping device for hardware forging. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Stamping is a manufacturing technology that uses the power of conventional or specialized stamping equipment to directly deform sheet metal within a die, thereby obtaining product parts with specific shapes, dimensions, and properties. The stamping process, along with the die, stamping equipment, and stamping material, constitute the three essential elements of stamping; only when these elements are combined can stamped parts be produced. In the forging process of hardware parts, stamping devices are required to form stamped parts; therefore, we are required to manufacture a stamping device for hardware forging.

[0004] Traditional metal forging stamping equipment requires spraying cooling water into the metal profile in the cavity through pipe nozzles during the stamping process. This can quickly cool the material and reduce thermal stress and deformation risks.

[0005] The position of the nozzle on the base plate is often relatively fixed, which limits the spray coverage of cooling water in the cavity. This makes the metal profiles prone to oxidation, deformation or coarse grains due to local overheating during stamping, thus affecting the product quality of the stamped parts.

[0006] In response to this problem, this utility model proposes a stamping device for metal forging to solve the above-mentioned issues. Utility Model Content

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0034] Please combine Figures 1 to 5 A stamping device for metal forging, comprising a base plate 1, a lower die holder 2, an upper die holder 3, a pressure plate 7, a pipe nozzle 15, and a transmission assembly.

[0035] The lower mold base 2 is located on the top of the base plate 1, and the top of the lower mold base 2 has a cavity 4;

[0036] The upper mold base 3 is vertically movable and is positioned above the lower mold base 2. The bottom of the upper mold base 3 is provided with a core 5 that mates with the cavity 4.

[0037] The pressure plate 7 is vertically elastically supported on the base plate 1, and can press and cooperate with the bottom of the lower mold base 2, and move down synchronously with the upper mold base 3;

[0038] The nozzle 15 is movably mounted on the top of the lower mold base 2, with its output end facing the cavity 4; and

[0039] The transmission assembly is mounted on the base plate 1 and can drive the pipe nozzle 15 to move relative to the cavity 4 in the length direction when the pressure plate 7 moves down.

[0040] In practice, before stamping, the metal material is placed into the cavity 4; during stamping, the upper die holder 3 moves vertically downward, causing the core 5 and the cavity 4 to close together, thus stamping the metal profile into a stamped part of the corresponding shape. The nozzle 15 sprays water onto the stamped part in the cavity 4 to cool it down. After stamping, the upper die holder 3 moves vertically upward, and the stamped part is removed from the cavity 4.

[0041] During this period, the lower mold base 2 moves vertically downwards and touches the pressure plate 7 at its bottom, causing the pressure plate 7 to move downwards synchronously. At this time, the transmission component drives the pipe nozzle 15 to move relative to the cavity 4 in the length direction, thereby realizing the moving water spray.

[0042] The advantage of this design is that the pressure plate 7 moves down synchronously with the upper mold base 3, which can reduce the impact force of the lower mold base 2 and the upper mold base 3 when they are closed, reduce the wear between the mold bases, and simultaneously increase the contact area between the water sprayed from the pipe nozzle and the hardware profile, thereby improving the cooling efficiency and effect of the hardware profile during stamping.

[0043] It should be noted that the lower mold base 2 of this application has a drainage channel (not shown) connecting to the bottom of the cavity 4, so as to promptly drain the water in the cavity 4 that has participated in the heat exchange and cooling of the hardware profile. The input end of the pipe nozzle 15 is connected to a water supply device (not shown) through a corresponding water pipe.

[0044] In one embodiment, a guide rod 6 parallel to the moving direction of the upper mold base 3 is fixed on the top of the base plate 1, and a pressure plate 7 is slidably sleeved on the outside of the guide rod 6. A first spring (not shown) is sleeved on the outside of the guide rod 6, and the two ends of the first spring are respectively connected to the top wall of the base plate 1 and the bottom wall of the pressure plate 7.

[0045] Thus, the guide rod 6 can limit the movement direction of the pressure plate 7 to vertical. When the upper mold base 3 closes and moves the pressure plate 7 downwards synchronously, the first spring will be compressed and deformed. When the mold closing is completed and the upper mold base 3 moves upwards to return to the initial height, the bottom of the upper mold base 3 disengages from the top of the pressure plate 7. At this time, the elastic force of the first spring is released, pushing the pressure plate 7 back to the initial height.

[0046] In one embodiment, the transmission assembly includes a cylinder 9, a push rod 8, and a reel 12.

[0047] The cylinder 9 is rotatably and vertically mounted on the top of the base plate 1; a spiral groove 10 is axially formed on the inner side of the cylinder 9;

[0048] The push rod 8 is inserted into the top of the cylinder 9, and the top of the push rod 8 is fixed to the bottom of the pressure plate 7; the outer wall of the push rod 8 is provided with a protrusion 11 that slides and engages with the groove 10; and

[0049] The reel 12 is sleeved and fixed to the outside of the cylinder 9. A tensioned rope is wound around the reel 12 and is used to pull and drive the nozzle 15 of the pipeline to move relative to it in the length direction of the cavity 4.

[0050] Thus, the downward movement of the pressure plate 7 can drive the top rod 8 to extend axially into the top of the cylinder 9, causing the protrusion 11 to continuously rub and squeeze the groove wall of the spiral groove 10, forcing the cylinder 9 to rotate in one direction. The cylinder 9 then drives the reel 12 to rotate, and the reel 12 performs a winding action to drive the pipe nozzle 15 to move relative to the cavity 4 in the length direction by pulling the rope 23.

[0051] It should be noted that a tensioning wheel 18 is installed on the top of the lower mold base 2. The free end of the pull rope 23 passes around the tensioning wheel 18 and is bolted to the pipe nozzle 15, which ensures that the pull rope is always kept taut.

[0052] In one embodiment, a track groove 16 parallel to the length direction of the cavity 4 is provided on the top of the base plate 1. A movable seat 13 is slidably disposed in the track groove 16, and a pipe rack 14 for clamping the pipe nozzle 15 is provided on the top of the movable seat 13. The pipe rack 14 has a U-shaped structure adapted to the pipe nozzle 15.

[0053] In this embodiment, the free end of the pull rope is fixed to the outer wall of the movable seat 13. When the pull rope does not pull the movable seat 13, the movable seat 13 is located on the side away from the corresponding reel 12 in the track groove 16. When the pull rope pulls the movable seat 13, it will move in the track groove 16 toward the direction closer to the corresponding reel 12, thus realizing the relative movement of the pipe nozzle 15 in the length direction of the cavity 4.

[0054] In one embodiment, a slide rod 17 parallel to the extension direction of the track groove 16 is provided in the track groove 16, and the movable seat 13 is slidably sleeved on the outside of the slide rod 17. A second spring (not shown) is sleeved on the outside of the slide rod 17, and the two ends of the second spring are respectively connected to the outer wall of the movable seat 13 and the corresponding groove wall of the track groove 16.

[0055] Thus, when the movable seat 13 moves in the track groove 16 toward the corresponding reel 12, the second spring is compressed. When the pressure plate 7 moves up to the initial height under the action of the first spring's elastic force recovery, it can drive the top rod 8 to extend axially out of the cylinder 9. The protrusion 11 rubs against the groove 10, realizing the opposite rotation of the cylinder 9 and the reel 12, causing the reel 12 to perform the line feeding action. At this time, the second spring's elastic force is released, synchronously driving the movable seat 13 to move back to the initial position in the track groove 16 away from the corresponding reel 12, and keeping the pull rope taut at all times.

[0056] In one embodiment, the two ends of the upper mold base 3 are slidably sleeved on two guide rods 6 respectively, and a bracket 22 is installed on the top of the base plate 1. A hydraulic cylinder 20 is installed at the cantilevered part of the top of the bracket 22, and the bottom of the hydraulic rod 21 of the hydraulic cylinder 20 is fixedly connected to the top of the upper mold base 3.

[0057] Thus, the hydraulic rod 21 of the hydraulic cylinder 20 can drive the upper mold base 3 to move vertically, thereby realizing the mold closing and opening operations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0059] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
