Description

Technical Field

[0001] This utility model relates to the field of hot forming stamping technology, and more specifically to an automatic material handling device for hot forming stamping. Background Technology

[0002] Hot forming stamping involves heating metal raw materials to a high temperature before stamping. Because the metal raw materials are more plastic after heating, they are easier to form. This processing method is suitable for the processing of many automotive parts in the automotive manufacturing industry, especially the forming of sheet metal.

[0003] During processing, the mold extrudes the high-temperature raw material to form it into a corresponding workpiece. At this time, the workpiece is still in a high-temperature state. Therefore, in the existing technology, a material handling device is often used to remove the formed workpiece from the mold.

[0004] However, when the material handling device is working, it needs to wait for the originally merged mold to fully open before it can start handling the material. Only after the material handling device has completely exited the mold area can the mold close again and enter the next round of stamping. This can easily cause pauses in the material handling process, which can easily lead to low material handling efficiency and low stamping efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an automatic material handling device for hot forming stamping. The operation of the material handling device is synchronously controlled by the up and down movement of the upper mold, making the transition between stamping and material handling more seamless and improving the efficiency of material handling and stamping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic material handling device for hot forming stamping, used to remove a workpiece that has been formed between an upper mold and a lower mold. The upper mold is located above the lower mold. The heated metal raw material is placed between the upper mold and the lower mold. The upper mold moves downward to clamp the metal raw material between the upper mold and the lower mold, thereby using external force to form the metal raw material. The device includes a base plate, and a sliding block is slidably connected to the top of the base plate via a slide rail. The top of the sliding block is provided with two material picking inserts for picking up materials. The front ends of the material picking inserts face the upper mold and the lower mold, and the material picking inserts are flush with the top of the lower mold. Both ends of the sliding block are rotatably connected to control rods. The upper mold has a detachable mounting plate on the side facing the sliding block. During the stamping process, the mounting plate will move up and down synchronously with the upper mold. The end of the control rod away from the sliding block is hinged to the mounting plate.

[0007] Furthermore, the top of the sliding block is provided with a lifting block, and two hydraulic cylinders are provided on both the front and rear sides of the lifting block. The sliding block can be adjusted by sliding up and down at the outer end of the fixed bracket, which can drive the material picking plate to move up and down.

[0008] Furthermore, connecting plates are fixedly provided at both ends of the hydraulic cylinder, and the two connecting plates are respectively connected to the sliding block and the lifting block by bolts.

[0009] Furthermore, a fixed bracket is fixedly provided at the top of the lifting block, and the cross-section of the fixed bracket is rectangular.

[0010] Furthermore, the outer end of the fixed bracket is fitted with two symmetrical adjusting slides, and the outer end of the adjusting slides is provided with fastening bolts by threads.

[0011] Furthermore, two material-picking inserts are respectively fixedly installed at the front end of two adjusting slides. The top of each material-picking insert is provided with an upper clamping plate via a hinge. An electric push rod is hinged to the top of the upper clamping plate, and the rear end of the electric push rod is hinged to the corresponding adjusting slide.

[0012] Furthermore, the front end of the material-taking insert is an inclined plate, and the thickness of the inclined plate gradually decreases from back to front. The special shape of the inclined plate makes it easier to insert into the gap between the workpiece and the lower mold.

[0013] Furthermore, a row of flexible metal wires is fixedly provided at the front end of the inclined plate so as to be inserted into the gap between the mold and the lower mold. The flexible metal wires are flexible and thin, so they are easier to insert into the gap.

[0014] The technical effects and advantages of this utility model are as follows: This utility model connects the mounting plate to the upper mold. During the stamping process, the upper mold moves up and down, driving the mounting plate. The sliding block is driven to slide back and forth by the control linkage. The material picking insert at the top of the sliding block moves accordingly to complete the material picking. Therefore, the operation of this material picking device is synchronously controlled by the up and down movement of the upper mold. The process of stamping and material picking is more seamless, improving the efficiency of material picking and stamping. This invention features a beveled blade and a flexible metal wire at the front end of the material-retrieving insert. The flexible metal wire is pliable and slender, making it easier to insert into gaps. The rear end of the flexible metal wire is connected to the beveled blade. Once the flexible metal wire is inserted into the gap, it guides the beveled blade into the gap, which in turn facilitates the material-retrieving insert to scoop up the workpiece, thus improving the material-retrieving efficiency.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Refer to the instruction manual appendix Figures 1-5 This utility model provides an automatic material handling device for thermoforming stamping, used to take out the workpiece that has been formed between the upper mold 7 and the lower mold 8. The upper mold 7 is located above the lower mold 8 and includes a base plate 1. The top of the base plate 1 is slidably connected to a sliding block 2 via a slide rail. The top of the sliding block 2 is provided with two material picking inserts 3 for picking up materials. The front ends of the material picking inserts 3 face the upper mold 7 and the lower mold 8, and the material picking inserts 3 are flush with the top of the lower mold 8. Both ends of the sliding block 2 are rotatably connected to control rods 6. The upper mold 7 is provided with a detachable mounting plate 4 on the side facing the sliding block 2. The end of the control rod 6 away from the sliding block 2 is hinged to the mounting plate 4.

[0019] The heated metal material is placed between the upper mold 7 and the lower mold 8. The upper mold 7 moves downward, clamping the metal material between the upper mold 7 and the lower mold 8, thereby using external force to shape the metal material. This invention requires the mounting plate 4 to be installed on the upper mold 7. During the stamping process, the mounting plate 4 will move up and down synchronously with the upper mold 7. As the upper mold 7 stamps downward, the mounting plate 4 moves down accordingly. During the downward movement of the mounting plate 4, it pushes the control linkage 6, which in turn pushes the sliding block 2 to move along the slide rail and away from the lower mold 8. The material picking piece 3 on the sliding block 2 also moves away from the lower mold 8 as a result. After the stamping is completed, the upper mold... As the workpiece 7 moves upward away from the lower mold 8, it will cause the mounting plate 4 to move upward. The mounting plate 4 pulls the control linkage 6 and drives the sliding block 2. The sliding block 2 and the material-retrieving insert 3 on its top will gradually approach the lower mold 8. After the material-retrieving insert 3 contacts the top of the lower mold 8, as the material-retrieving insert 3 moves, it can insert into the gap between the workpiece and the lower mold 8, thereby lifting the workpiece and clamping and fixing it. After the workpiece is lifted and fixed, the upper mold 7 moves downward again for the next stamping. The material-retrieving insert 3 and the workpiece it clamps will gradually move away from the lower mold 8 as the upper mold 7 moves downward, thus completing the material-retrieving work after forming. In this way, the operation of the material handling device is synchronously controlled by the up-and-down movement of the upper mold 7. It is not necessary to wait for the upper mold 7 to be fully lifted after stamping before material handling, nor is it necessary to wait for material handling to be completed before stamping. The transition between stamping and material handling is more seamless, which improves the efficiency of material handling and stamping.

[0020] The height of the material-retrieving insert 3 can be adjusted according to the height of different lower molds 8, such as... Figure 3 , Figure 4 As shown, the top of the sliding block 2 is provided with a lifting block 201, and the top of the lifting block 201 is fixedly provided with a fixed bracket 5. The cross-section of the fixed bracket 5 is rectangular, and two left-right symmetrical adjusting slides 501 are sleeved on the outer end of the fixed bracket 5. The outer end of the adjusting slide 501 is provided with a fastening bolt by thread. Tightening the fastening bolt can fix the adjusting slide 501 to the outer end of the fixed bracket 5.

[0021] The sliding adjustment slide 501 at the outer end of the fixed bracket 5 can drive the material picking insert 3 to move up and down, thereby adjusting the height of the material picking insert 3 according to the height of the lower mold 8, so that the material picking insert 3 can be close to the upper surface of the lower mold 8 to pick up the workpiece.

[0022] To facilitate lifting the workpiece, such as Figure 4 , Figure 5As shown, two material picking inserts 3 are fixedly mounted on the front ends of the two adjusting slides 501. The front end of the material picking insert 3 is a slanted piece 303. The thickness of the slanted piece 303 gradually decreases from back to front. The special shape of the slanted piece 303 makes it easier to insert into the gap between the workpiece and the lower mold 8. A row of tough metal wires 304 is fixedly mounted on the front end of the slanted piece 303 so that it can be inserted into the gap between the upper mold 7 and the lower mold 8.

[0023] As the pick-up insert 3 gradually approaches the workpiece until it is lifted up, the tough metal wire 304 will first come into contact with the gap between the workpiece and the lower mold 8. The tough metal wire 304 is flexible and thin, so it is easier to insert into the gap. The rear end of the tough metal wire 304 is connected to the inclined plate 303. After the tough metal wire 304 is inserted into the gap, it can guide the inclined plate 303 to insert into the gap, which in turn facilitates the pick-up insert 3 to insert into the gap, lift up the workpiece and fix it.

[0024] After lifting the workpiece, it needs to be clamped and secured, such as... Figure 4 As shown, the top of the material picking insert 3 is provided with an upper clamping plate 301 via a hinge, and an electric push rod 302 is hinged to the top of the upper clamping plate 301. The rear end of the electric push rod 302 is hinged to the corresponding adjusting slide 501.

[0025] When the front end of the pick-up insert 3 is inserted into the gap between the lower mold 8 and the workpiece, the edge of the workpiece is located at the top of the pick-up insert 3. At this time, the electric push rod 302 is extended, and the electric push rod 302 will push the upper clamping plate 301, causing the upper clamping plate 301 to rotate and gradually approach the pick-up insert 3, until the edge of the workpiece is picked up and clamped between the pick-up insert 3 and the upper clamping plate 301, thereby clamping and fixing the workpiece at the pick-up insert 3.

[0026] After fixing the workpiece, lift it up to separate it from the lower mold 8, as shown. Figure 2 As shown, the lifting block 201 is provided with two hydraulic cylinders 202 on both the front and rear sides. Each hydraulic cylinder 202 has a connecting plate fixed at both ends. The two connecting plates are respectively connected to the sliding block 2 and the lifting block 201 by bolts.

[0027] After the workpiece is scooped up and clamped, the hydraulic cylinder 202 will extend and push the lifting block 201 upward. The fixed bracket 5 and the material picking insert 3 at the top of the lifting block 201 will move upward simultaneously, lifting the workpiece as a whole so that it can be separated from the lower mold 8. The separated workpiece will be smoothly pulled and removed when the sliding block 2 slides away from the lower mold 8.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
