Description

Technical Field

[0001] The utility model relates to the technical field of calorimetric cup processing, in particular to an extrusion tooling for a calorimetric cup. Background Art

[0002] At present, the domestic main method of producing calorimetric cups is free forging processing technology (the calorimetric cup involved in the utility model is an instrument specially used to measure the heat of a certain gas substance on aerospace equipment). Since the raw materials used in this product are very expensive, the use of this processing technology results in a very high consumption of raw materials and expensive manufacturing costs. The free forging processing technology can meet customer needs in the sample and small batch production stages, but the cost is too high and the efficiency is low.

[0003] With the increase in production demand and cost control requirements, the above processing method is obviously unable to meet production and customer needs. Based on this, it is extremely important to provide a processing method that can not only meet product performance, but also significantly reduce manufacturing costs and meet customer batch production needs. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an extrusion tooling for a calorimetric cup, which adopts extrusion technology, can not only meet the product performance requirements, but also greatly reduce production costs, improve production efficiency, and meet customers' mass production needs.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The invention discloses an extrusion tool for a calorimetric cup, comprising a lower workbench, a lower concave die arranged at the top of the lower workbench, an upper punch arranged just above the lower concave die and capable of vertical displacement, and a material stripping device arranged on the lower concave die.

[0007] Preferably, the material stripping device includes a connecting rod arranged on the outer wall of the lower die, and a material stripping plate arranged on the top end of the connecting rod.

[0008] Preferably, a positioning plate is provided on the top of the lower workbench, and the lower concave mold is sleeved on the outside of the positioning plate.

[0009] Preferably, the outer wall of the lower die is provided with a stepped platform, a pressing plate is provided on the stepped platform, and the pressing plate is connected to the lower workbench through a first screw.

[0011] Preferably, the upper punch and the upper punch pad, as well as the upper punch pad and the upper workbench are connected via second screws.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By providing a lower concave die and an upper punch matched with the lower concave die, the calorimetric cup can be produced by extrusion technology during the downward pressing of the upper punch; this production method can meet the performance requirements of the workpiece, and at the same time can greatly reduce the consumption of expensive raw materials and the processing time required for mechanical processing, greatly reduce production costs, improve production efficiency, and meet customers' needs for mass production; in addition, the utility model provides a material return device, which can press the workpiece adhered to the upper punch downward after the workpiece production is completed and the upper punch is moved up, so as to achieve the purpose of material return and avoid the workpiece sticking to the upper punch, which makes it inconvenient to take out the material.

[0017] Below in conjunction with the attached Figure 1 to Figure 2 , the technical solutions in the embodiments of the utility model are clearly and completely described, but the protection scope of the utility model is not limited to the following.

[0018] Example 1

[0019] At present, the domestic main method of producing calorimetric cups is free forging technology. Since the raw materials used in this product are very expensive, the use of this processing technology results in a very high consumption of raw materials and expensive manufacturing costs. Free end processing technology can meet customer needs in the sample and small batch production stages, but the cost is too high and the efficiency is low.

[0020] With the increase in production demand and cost control requirements, the above processing method is obviously unable to meet production and customer needs. Based on this, the utility model provides an extrusion tooling for a calorimetric cup, such as Figure 1 and Figure 2As shown, it includes a lower workbench 1, a lower die 2 arranged at the top of the lower workbench 1, an upper punch 3 arranged just above the lower die 2 and capable of vertical displacement, and a material stripping device arranged on the lower die 2. Figure 1 As shown, an upper punch pad 9 is installed on the top of the upper punch 3, and an upper workbench 10 is installed on the top of the upper punch pad 9. The upper workbench 10 is connected to the upper slider of the press (existing technology, not shown in the figure). Figure 1 As shown, the upper punch 3 and the upper punch pad 9, as well as the upper punch pad 9 and the upper workbench 10 are connected by second screws.

[0021] Working principle: Calculate the working size of the upper punch 3 head and the cavity size of the lower die 2 according to the designed forging drawing, and determine the length of the upper punch 3 and the height of the lower die 2 according to the working space size of the equipment. Then install it. Specifically, connect the upper punch 3 to the upper punch pad 9 with the second screw, and connect the upper punch pad 9 to the workbench with the second screw; assemble the stripper plate 5 on the lower die 2, etc. After the installation is completed, start the press to check whether the clearance of the moving part is reasonable. After confirming that it is correct, you can start the product trial production.

[0022] After the tooling is preheated and lubricated, the heated and blanked workpiece 11 is placed in the lower concave die 2, and the press is started to extrude. After the size of the workpiece 11 is in place, the press returns. If the workpiece 11 sticks to the punch, it is withdrawn by the material withdrawal device and falls into the lower concave die 2. Since the workpiece 11 is relatively long and exceeds the space size of the equipment, the workpiece 11 can only be taken out in a semi-mechanized way. That is, the lower concave die 2 is forked away from the lower workbench 1 by a forklift, and the workpiece 11 falls out by itself under the action of gravity. Then the lower concave die 2 is forked to the workbench again by a forklift and installed to prepare for the next extrusion. This cycle completes the mass production of products.

[0023] Further, on the basis of Example 1, the material stripping device includes a connecting rod 4 arranged on the outer wall of the lower die 2, and a material stripping plate 5 arranged on the top of the connecting rod 4. In this solution, when the upper punch 3 moves upward, if the workpiece 11 sticks to the upper punch 3, it will move upward with it. At this time, the push plate has a downward pressing action on the workpiece 11, thereby making the workpiece 11 detach from the upper punch 3 and fall into the lower die 2, thereby effectively achieving the purpose of material stripping.

[0024] Further, in order to realize the positioning of the lower die 2, based on Example 1, as Figure 1 and 2As shown, a positioning plate 6 is fixedly provided on the top of the lower workbench 1, and the lower die 2 is firmly sleeved on the outside of the positioning plate 6. When the forklift forks the lower die 2 away from the lower workbench 1, the lower die 2 is separated from the positioning plate 6, and the workpiece 11 falls to the lower end of the lower die 2 under the action of gravity.

[0025] Further, on the basis of Example 1, in order to limit the lower die 2, as shown in FIG. Figure 1 and Figure 2 As shown, the outer wall of the lower die 2 is provided with a stepped platform 7, and a pressing plate 8 is provided on the stepped platform 7, and the pressing plate 8 is connected to the lower workbench 1 through a first screw. Specifically, the stepped platform 7 can be annular, or multiple and evenly distributed on the outer wall of the lower die 2. Figure 1 and Figure 2 The circular stepped platform 7 is shown in FIG.

[0026] In this solution, by providing the stepped platform 7 , the pressing plate 8 and the first screw, the lower die 2 can be firmly fixed on the lower workbench 1 to ensure the smooth operation of the lower die 2 .
