Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a rapid prototyping jig for sheet metal parts. Background Art

[0002] Sheet metal forming mainly includes the following common methods:

[0003] 1. Laser cutting: Use a high-power density laser beam to irradiate the surface of sheet metal materials, causing the materials to melt, evaporate or burn quickly, thereby achieving precise cutting. Laser cutting is fast and accurate, and can directly generate complex sheet metal parts from CAD data, greatly shortening the molding cycle.

[0004] 2. CNC punching machine: By programming and inputting the required sheet metal shape data, the CNC punching machine can realize accurate and fast punching, blanking, bending, shallow drawing and other operations, complete multiple processes at one time, and improve production efficiency.

[0005] 3. Bending machine: With the help of CNC program, it can quickly and accurately position and bend the cut or punched sheet metal parts to achieve rapid forming of three-dimensional shapes.

[0006] 4. Hydraulic forming / stamping: For sheet metal parts with larger volume and complex structure, rapid forming can be carried out by hydraulic press or stamping machine, which is especially suitable for mass production.

[0007] 5. 3D printing technology: In recent years, metal 3D printing technology has also emerged in the rapid prototyping of sheet metal parts, especially technologies such as selective laser melting (SLM) and direct energy deposition (DED), which can directly manufacture highly complex sheet metal parts from powder or wire, greatly improving design freedom and production flexibility.

[0008] 6. Mold stamping: For products that are mass-produced and have relatively fixed shapes, customized molds can be used for batch stamping production. Although the initial mold development time is long, once it is put into production, the production speed of a single piece is very fast.

[0009] 7. Composite forming technology: Combining the above-mentioned technical means, such as laser cutting followed by forming by hydraulic press, can achieve fast and accurate sheet metal production. By rationally selecting and combining the above rapid prototyping technologies, the design and production cycle of sheet metal parts can be significantly shortened, and product quality and production efficiency can be effectively improved.

[0010] In industrial production operations, in order to meet the needs of rapid prototyping of sheet metal parts, die stamping is usually used. However, the existing die usually includes a fixed die and a movable die, and a driving part is connected to the movable die. After the driving part drives the movable die to approach the fixed die, since the sheet metal part to be processed is located between the fixed die and the movable die, the sheet metal part can be quickly formed after being squeezed by the movable die and the fixed die.

[0011] It can be seen that the movable mold is directly involved in the molding, which makes the movable mold easy to wear and the entire mold cannot be used for a long time. Summary of the invention

[0012] The purpose of the utility model is to provide a rapid prototyping jig for sheet metal parts with high operating efficiency and compact structure in view of the above problems existing in the prior art.

[0013] The purpose of the utility model can be achieved through the following technical solutions:

[0014] A rapid prototyping jig for sheet metal parts includes a flat base plate, and is characterized in that it also includes a driving member, a movable block, a fixed block and a molding member, wherein the driving member is fixedly connected to one end of the base plate, the driving member is connected to the inner end of the movable block, the fixed block is fixedly connected to the other end of the base plate, the side of the fixed block has a concave molding cavity, and the molding member is fixedly connected to the outer end of the movable block and the molding member is opposite to the molding cavity.

[0015] The rapid prototyping jig of sheet metal creatively connects the forming part to the movable block. After the sheet metal to be processed is placed between the fixed block and the movable block, the driving part drives the movable block to move toward the fixed block, and after the forming part is embedded in the forming cavity of the fixed block, the sheet metal can be quickly extruded and formed.

[0016] In the above-mentioned rapid prototyping jig for sheet metal parts, the upper part of the fixed block has a connecting hole communicating with the molding cavity, and also includes a stopper, the stopper is penetrated at the connecting hole and the lower end of the stopper is located at the molding cavity, and the above-mentioned molding part is directly opposite to the inner end of the stopper.

[0017] After the stopper is embedded in the connecting hole, the stopper can be stably connected to the fixed block. Since the molded part and the stopper are directly opposite, the molded part and the stopper are subjected to force during the molding process. After long-term use, the worn molded part and the stopper can be replaced separately, which effectively reduces the use cost of the fixture.

[0018] In the above-mentioned rapid prototyping jig for sheet metal parts, the inner side of the stopper has a protruding positioning edge, and the side of the connection hole has a connecting edge matching the positioning edge, and the connecting edge is embedded in the positioning edge.

[0019] The positioning edge and the stopper are an integrated structure. Since the connection hole matches the stopper, the connection stability can be ensured after the stopper is connected to the positioning hole.

[0020] In the above-mentioned rapid prototyping jig for sheet metal parts, the movable block is in the shape of a long plate, and a guide structure is provided between the movable block and the bottom plate to enable the movable block to move smoothly.

[0021] The movable block can move smoothly under the action of the guide structure.

[0022] In the above-mentioned rapid prototyping jig for sheet metal parts, the guide structure includes a guide block 1 and a guide block 2 fixedly connected to the bottom plate, and the above-mentioned movable block is located between the guide block 1 and the guide block 2.

[0023] Since both sides of the movable block are respectively limited by the guide block 1 and the guide block 2, the movable block can move smoothly.

[0024] In the above-mentioned rapid prototyping jig for sheet metal parts, the molding part is in the shape of a long plate, the inner end of the molding part is fixedly connected to the movable block, and the outer end of the molding part is directly opposite to the stop block.

[0025] The outer end of the molded part is telescopically movable.

[0026] In the above-mentioned rapid prototyping jig for sheet metal parts, the stopper and the forming part form a forming unit, the number of the forming units is two, and the two forming units are symmetrically distributed at both ends of the movable block.

[0027] The two forming units can form two corresponding set structures on the sheet metal part at one time.

[0028] In the above-mentioned rapid prototyping jig for sheet metal parts, the movable block is detachably connected to the driving member.

[0029] By replacing different movable blocks in the jig, different sheet metal parts can be processed, which appropriately improves the applicability of the jig.

[0030] In the above-mentioned rapid prototyping jig for sheet metal parts, the driving member is a cylinder, a connecting plate is fixedly connected to the piston rod of the cylinder, and the connecting plate is detachably connected to the movable block.

[0031] The connecting plate provides enough space for the movable block to be detachably connected. In other words, the driving member is indirectly connected to the movable block through the connecting plate.

[0032] In the above-mentioned rapid prototyping jig for sheet metal parts, the inner end of the movable block has a positioning recess that runs through from top to bottom, the size of the positioning recess at the bottom is larger than the size at its end, and the connecting plate has a connecting pin that matches the positioning recess, and the connecting pin is embedded in the positioning recess.

[0033] Since the positioning notch matches the connecting pin, the movable block can be stably connected to the connecting plate by being inserted from top to bottom.

[0034] In the above-mentioned rapid prototyping jig for sheet metal parts, the number of the positioning recesses is several, and the several positioning recesses are evenly distributed along the length direction of the movable block, and the above-mentioned connecting pins are arranged in a one-to-one correspondence with the positioning recesses.

[0035] A plurality of positioning notches and connecting pins that match one to one can enable the movable block to be stably connected to the connecting plate.

[0036] Compared with the prior art, the rapid prototyping jig for sheet metal parts can quickly form the sheet metal parts after the forming parts are embedded in the forming cavity of the fixed block, so the operation efficiency is relatively high.

[0037] At the same time, the molded parts and the corresponding stops are the main stress-bearing parts of the entire fixture. Therefore, the molded parts and the stops can be replaced separately after long-term use, which appropriately reduces the use cost of the fixture and extends the service life of the fixture, and has high practical value.
