Description

Technical Field

[0001] This utility model relates to the field of electric arc additive manufacturing equipment technology, and in particular to a pressure-resistant structure for electric arc additive manufacturing equipment. Background Technology

[0002] Arc additive manufacturing equipment uses arc discharge technology to melt metal wires and stack them layer by layer to form metal parts with complex geometries. Its hardware structure includes a gun cable assembly, a wire feeding mechanism, and a CNC machine tool. The arc additives to be formed often need to undergo surface processing, such as stamping to improve surface quality or to modify the shape.

[0003] In practical use, the stamping structure of existing electric arc additive manufacturing equipment requires the operator to clamp the electric arc additive for positioning, which is time-consuming and labor-intensive. In addition, the lack of a pressure-resistant structure on the load-bearing base affects the stability of the load-bearing base. This paper proposes a pressure-resistant structure for electric arc additive manufacturing equipment to solve the above problems. Utility Model Content

Furthermore, the lack of a pressure-resistant structure on the load-bearing base affects the stability of the load-bearing base.

The buffer pads and buffer airbags are all rubber products.

[0009] Preferably, the buffer mechanism includes a cross-shaped block inserted into the groove. The lower end of the vertical section of the T-shaped support is fixedly connected to the upper end of the center of the cross-shaped block. Four hydraulic buffers are fixedly installed on the bottom of the groove. The upper ends of the four hydraulic buffers are fixedly connected to the lower ends of the cross-shaped block. A rectangular limiting block is provided at the end of the cross-shaped block away from the T-shaped support. Rectangular limiting grooves are provided on the inner walls around the center of the groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A pressure-resistant structure for an electric arc additive manufacturing equipment includes a manufacturing equipment body 1, a stamping seat 2 on the manufacturing equipment body 1, a U-shaped load-bearing base 3 on the upper end of the manufacturing equipment body 1 opposite to the stamping seat 2, two slots 4 on the upper end of the manufacturing equipment body 1, and vertical sections on both sides of the U-shaped load-bearing base 3 respectively inserted into the two slots 4. A positioning assembly is provided on the upper end of the horizontal section of the U-shaped load-bearing base 3. The positioning assembly includes hydraulic cylinders 7 respectively fixedly installed on the upper end of the horizontal section near the four corners of the U-shaped load-bearing base 3. The piston rods of the four hydraulic cylinders 7 are arranged in pairs facing each other. The free ends of the piston rods of the two hydraulic cylinders 7 on the same side are fixedly installed with the same L-shaped clamping plate 8. The opposite side walls of the vertical sections of the two L-shaped clamping plates 8 are fixedly mounted. A buffer pad 9 is fixedly connected to the upper end of the U-shaped load-bearing base 3. The electric arc additive is placed on the upper end of the U-shaped load-bearing base 3, so that the hydraulic cylinder 7 at the upper end of the U-shaped load-bearing base 3 drives the L-shaped clamping plate 8 and the rubber buffer pad 9 to clamp and position the electric arc additive. No operator clamping and positioning is required, saving time and effort and reducing labor intensity. The buffer pad 9 can protect the clamped and positioned electric arc additive and prevent damage to the electric arc additive. Several buffer airbags 10 are fixedly installed at the lower end of the horizontal section near the vertical section on both sides of the U-shaped load-bearing base 3. The lower ends of the buffer airbags 10 are all fixedly connected to the upper end of the manufacturing equipment body 1. The buffer pad 9 and the buffer airbags 10 are both rubber products. The rubber buffer airbags 10 can provide buffering for the force on the U-shaped load-bearing base 3.

[0024] The manufacturing equipment body 1 has a groove 5 located at the upper end of the inner side of the U-shaped load-bearing base 3. A buffer mechanism is installed in the groove 5, and a T-shaped support 6 is installed on the buffer mechanism. The horizontal section of the U-shaped load-bearing base 3 is fixedly connected to the upper end of the T-shaped support 6. The buffer mechanism includes a cross-shaped block 11 inserted into the groove 5. The lower end of the vertical section of the T-shaped support 6 is fixedly connected to the upper end of the center position of the cross-shaped block 11. Four hydraulic buffers 12 are fixedly installed on the bottom of the groove 5, and the upper ends of the four hydraulic buffers 12 are all connected to the upper end of the center position of the cross-shaped block 11. The lower end of the cross-shaped block 11 is fixedly connected. A rectangular limiting block 13 is provided at the end of the cross-shaped block 11 away from the T-shaped support 6. Rectangular limiting grooves 14 are provided on the inner walls around the center of the groove 5. When the rectangular limiting blocks 13 move within the rectangular limiting grooves 14, the U-shaped load-bearing base 3, in conjunction with the T-shaped support 6, drives the cross-shaped block 11 to move smoothly vertically along the groove 5. The four rectangular limiting blocks 13 are respectively inserted into the four rectangular limiting grooves 14 and slide against each other. Each of the four rectangular limit blocks 13 has a limiting rod 15 at its bottom. The upper ends of each of the four rectangular limit blocks 13 located within the rectangular limit groove 14 have circular through holes 16. The four limiting rods 15 are vertically inserted through the four circular through holes 16. The lower ends of each of the four rectangular limit blocks 13 are fixedly connected to a buffer spring 17, which fixes the U-shaped load-bearing base 3 onto the T-shaped support 6 and the buffer airbag 10, so that the vertical section of the U-shaped load-bearing base 3 is inserted into the slot 4. The U-shaped load-bearing base 3, under the force of the T-shaped support 6, drives the cross-shaped block 1... 1. Under the limiting action of the rectangular limiting block 13 and the rectangular limiting groove 14, the buffer spring 17 and the hydraulic buffer 12 are compressed along the limiting rod 15, so that the buffer airbag 10, together with the buffer spring 17 and the hydraulic buffer 12, provides buffering for the U-shaped load-bearing base 3, thereby improving the stability of the U-shaped load-bearing base 3. The four buffer springs 17 are respectively sleeved on the four limiting rods 15. The rectangular limiting block 13 and the cross-shaped block 11 are integrally cast. The lower end of the limiting rod 15 is threadedly connected to the bottom of the rectangular limiting groove 14.

[0025] In use, the lower end of the U-shaped load-bearing base 3 is fixed to the upper end of the T-shaped support base 6 and several buffer airbags 10, so that the vertical sections on both sides of the U-shaped load-bearing base 3 are respectively inserted into the slots 4 on both sides. The electric arc additive is placed on the upper end of the U-shaped load-bearing base 3, so that the hydraulic cylinder 7 at the upper end of the U-shaped load-bearing base 3 drives the L-shaped clamping plate 8 and the rubber buffer pad 9 to clamp and position the electric arc additive. No operator clamping and positioning is required, saving time and effort, reducing labor intensity, and allowing the U-shaped load-bearing base to be used. 3 is fixed on the T-shaped support 6 and the buffer airbag 10, so that the vertical section of the U-shaped load-bearing base 3 is inserted into the slot 4. The U-shaped load-bearing base 3 is subjected to force and, in conjunction with the T-shaped support 6, drives the cross-shaped block 11 to compress the buffer spring 17 and the hydraulic buffer 12 along the limiting rod 15 under the limiting action of the rectangular limiting block 13 and the rectangular limiting groove 14. This allows the buffer airbag 10, in conjunction with the buffer spring 17 and the hydraulic buffer 12, to provide buffering for the U-shaped load-bearing base 3 and improve the stability of the U-shaped load-bearing base 3.
