Description

Technical Field

[0001] The utility model relates to the field of mold production equipment, in particular to a mold electric spark and wire cutting bracket structure. Background Art

[0002] At present, aluminum profile extrusion dies are usually processed by electric spark machines or wire cutting machines. Since aluminum profile extrusion dies are mostly cylindrical components, and generally require axially penetrating forming holes to be opened on the components; and because the electrode rods on existing electric spark machines and the working parts of the electrode wires on wire cutting machines are arranged vertically. Therefore, in general, the cylindrical components are vertically installed and positioned on the electric spark machines and wire cutting machines. Only in this way can the cylindrical components be conveniently processed by electric spark machines or wire cutting machines. However, in order to meet some special extrusion molding needs, cylindrical components with forming protrusions on the end faces have appeared, and forming planes are generally processed on the side walls of the forming protrusions. When producing such components, it is difficult to process a convex part with a forming plane if an EDM machine or a wire cutting machine is still used, and vertical installation and positioning are adopted. Although a cylindrical component can be placed horizontally to meet the function of the electrode rod of the EDM machine or the electrode wire of the wire cutting machine, the horizontally placed cylindrical component is very easy to roll, and there is no related fixture on the existing EDM machine and wire cutting machine to limit the horizontally placed cylindrical component, so it is impossible to process a convex part with a forming plane through the EDM machine and wire cutting machine. Therefore, it is very necessary to design a mold EDM and wire cutting bracket structure to solve the above technical problems. Utility Model Content

[0029] like Figures 1 to 4 As shown, a mold electric spark and wire cutting support structure described in the utility model includes a rolling support bracket 1 and a clamping mechanism 2, wherein the clamping mechanism 2 is arranged on the rolling support bracket 1 or beside it.

[0030] The rolling support bracket 1 can be used on the mold EDM and wire cutting support structure to play a rolling support role for the cylindrical component of the aluminum profile extrusion molding die, so that it is convenient to adjust the cylindrical component by rolling, which can facilitate workers to adjust the molding convex part to a suitable angle when processing the molding convex part with a molding plane on the end face of the cylindrical component, so that it is convenient to process the molding convex part with a molding plane on the end face of the cylindrical component. The clamping mechanism 2 can play a clamping and positioning role for the aluminum profile extrusion molding die, which can help to stabilize and accurately position the mold, thereby facilitating the accurate role of EDM or wire cutting, and further improving the relevant processing quality.

[0031] like Figures 1 to 4 , Fig.15 As shown, the clamping mechanism 2 is a radial clamping mechanism for clamping one axial end of the cylindrical component. This can prevent the clamping mechanism 2 from blocking the end of the cylindrical component 10 with the molding protrusion 101, thereby preventing the clamping mechanism 2 from affecting the electric spark and wire cutting, and thus making it more convenient to carry out related processing; and this can also help to play a more stable and reliable clamping role for the cylindrical component 10 with a smaller axial size, which can help to improve the stability and reliability of the installation and positioning of the cylindrical component 10, thereby helping to further improve the reliability and applicability of the mold electric spark and wire cutting bracket structure.

[0032] like Figures 1 to 5As shown, the clamping mechanism 2 includes a positioning frame 21 and two clamping arms 22, the two clamping arms 22 are arranged side by side on the positioning frame 21, and at least one of the two clamping arms 22 can perform lateral reciprocating motion, and the clamping arm 22 capable of lateral reciprocating motion is provided with a locking structure 23 capable of locking it on the positioning frame 21, and a clamping gap 20 is formed between the two clamping arms 22. Such a clamping mechanism 2 can achieve a very good clamping effect, thereby further improving the stability and reliability of the installation and positioning of the cylindrical component.

[0033] like Figure 5 and Figure 7 As shown, the clamping arm 22 includes a limit block 221, a lifting frame 222, and a longitudinal clamping arm 223. The limit block 221 is arranged on the positioning frame 21. The lower end of the lifting frame 222 can be inserted into the limit block 221 in a vertical sliding manner. The limit block 221 is screwed with a first screw 224, and the first screw 224 can be pressed against the lifting frame 222. The longitudinal clamping arm 223 can be inserted into the lifting frame 222 in a longitudinal (longitudinal direction is the front-to-back direction) sliding manner. The lifting frame 222 is screwed with a second screw 225, and the second screw 225 can be pressed against the longitudinal clamping arm 223. In this way, the purpose of lifting and lowering and front-to-back adjustment of the clamping position can be achieved, thereby meeting more clamping requirements, and further helping to further improve the applicability of the mold EDM and wire cutting support structure.

[0034] like Figure 5 and Figure 8 As shown, the clamping arm 22 includes a limit frame 226 and two clamping rollers 227. The limit frame 226 is arranged on the positioning frame 21, and the two clamping rollers 227 are arranged side by side on the limit frame 226; the clamping rollers 227 on the two clamping arms 22 are arranged opposite to each other. This not only plays a very good clamping and positioning role, but also helps to make the cylindrical component roll more stable, thereby helping to further improve the reliability of the mold EDM and wire cutting bracket structure.

[0035] like Fig.16 As shown, when the cylindrical component 10 is a stepped shaft, four clamping rollers 227 can be clamped on the step 102 of the cylindrical component 10, which can better limit the effect.

[0036] like Figure 3 and Figure 8 As shown, the rolling center line of the clamping roller 227 extends longitudinally, and the clamping roller 227 is a step roller with a small front end and a large rear end. This can make the clamping roller 227 have a better clamping effect, thereby further improving reliability.

[0037] like Figure 5As shown, the positioning frame 21 is provided with a transversely extending T-shaped slot 211, the clamping arm 22 is provided with a T-shaped protrusion 228 matching the T-shaped slot 211, the T-shaped protrusion 228 is slidably embedded in the T-shaped slot 211, and the locking structure 23 includes at least one pressing screw screwed on the clamping arm 22, and the pressing screw can be pressed tightly on the positioning frame 21. This not only makes the transverse sliding of the clamping arm 22 very stable and accurate, but also makes the locking of the clamping arm 22 very stable and reliable, thereby helping to further improve the reliability of the mold EDM and wire cutting bracket structure.

[0038] like Figures 5 to 8 As shown, the positioning frame 21 is composed of a vertically arranged positioning plate, the T-shaped slot 211 is horizontally penetrated through the rear wall of the positioning frame 21, the clamping arm 22 includes a limit block 221, a vertical rod 201, a longitudinal rod 202, a positioning block 203, and two clamping rollers 227, the T-shaped protrusion 228 is arranged on the limit block 221, the top pressure screw is screwed on the limit block 221, the lower end of the vertical rod 201 can be vertically slidably placed on the limit block 221, the first screw 224 can be pressed tightly on the vertical rod 201, and the vertical rod 201 can be vertically slidably placed on the limit block 221. On the rod 201, a reinforcing block 2011 is arranged at the upper end of the vertical rod 201, the front end of the longitudinal rod 202 is connected to the rear wall of the positioning block 203, the rear end of the longitudinal rod 202 can be longitudinally slidably inserted into the reinforcing block 2011, the second screw 225 is screwed on the reinforcing block 2011, and the second screw 225 can be pressed tightly on the longitudinal rod 202, two clamping rollers 227 are arranged side by side on the front wall of the positioning block 203, and the rotation center lines of the two clamping rollers 227 are longitudinally extended. The vertical rod 201 and the reinforcing block 2011 together constitute a lifting frame 222; the longitudinal rod 202, the positioning block 203 and the two clamping rollers 227 together constitute a longitudinal clamping arm 223; the limiting block 221, the vertical rod 201, the longitudinal rod 202, the positioning block 203 and the reinforcing block 2011 together constitute a limiting frame 226. This not only satisfies the requirements of actual manufacturing and use very well, but also ensures that the clamping mechanism 2 has very high reliability and can better meet the requirements of clamping various components.

[0039] like Figure 5 As shown, a notch 212 is provided in the middle of the top surface of the positioning frame 21, and the notch 212 runs through the middle of the T-shaped slot 211. This not only reduces the use of raw materials, but also reduces the difficulty of opening the T-shaped slot 211; and the notch 212 can also reduce the shielding of the cylindrical component by the positioning frame 21, so that it is convenient for workers to detect the cylindrical component.

[0040] like Figure 6 As shown, in order to make the positioning block 203 have high structural strength, the positioning block 203 can be made into a block with an L-shaped horizontal cross section.

The positioning seat 12 that can slide horizontally is provided with at least one sliding locking component 14 that can lock it on the positioning plate 11. The two longitudinal rollers 13 are respectively arranged on the two positioning seats 12, and a supporting gap 30 is formed between the two longitudinal rollers 13. Such a rolling support bracket 1 can help to stably support cylindrical components of different diameters, thereby helping to improve the applicable scope of the mold electric spark and wire cutting support structure, and further helping to further improve the reliability and applicability of the mold electric spark and wire cutting support structure.

[0042] like Figure 3 , Figure 4 and Fig. 9 As shown, the sliding locking assembly 14 is a locking bolt, and the positioning plate 11 is provided with a transversely extending T-shaped guide groove 111, and the nut end of the locking bolt is slidably embedded in the T-shaped guide groove 111, and the locking bolt is vertically penetrated through the positioning seat 12, and the locking bolt can lock the positioning seat 12 on the positioning plate 11. In this way, the positioning seat 12 can be conveniently and stably locked on the positioning plate 11, thereby helping to further improve reliability and applicability.

[0043] like Fig. 9 As shown, the nut end of the locking bolt is a T-shaped embedded head 141, the width of the T-shaped embedded head 141 is smaller than the outer groove width of the T-shaped guide groove 111, the length of the T-shaped embedded head 141 is larger than the outer groove width of the T-shaped guide groove 111, and the length of the T-shaped embedded head 141 is smaller than the inner groove width of the T-shaped guide groove 111, so that the nut end of the locking bolt can be moved in and out from any notch position of the T-shaped guide groove 111 by rotating the locking bolt, thereby helping to improve the convenience of assembly, disassembly and maintenance.

[0044] like Figures 9 to 11 As shown, a pinion 15 is provided on the positioning seat 12, and a hand wheel 16 for rotating the pinion 15 is provided on the pinion 15. A large gear 17 is provided on the end of the longitudinal roller 13, and the large gear 17 is meshed with the pinion 15. In this way, the longitudinal roller 13 can be rolled with a small force, and this can ensure that the rolling of the longitudinal roller 13 is very stable, which helps to improve the convenience of rolling and adjusting the cylindrical component, and further helps to further improve the convenience of use.

[0045] like Figures 9 to 11As shown, a protective cover 18 covering the pinion 15 and the gear 17 is provided on the positioning seat 12. This can not only prevent dust and debris from falling on the pinion 15 and the gear 17, but also prevent operators from contacting the pinion 15 and the gear 17, thereby delaying the aging speed and improving safety.

[0046] like Figures 10 to 12 As shown, the positioning seat 12 includes a bottom plate 121 and two support plates 122. The two support plates 122 are arranged side by side on the bottom plate 121. The front and rear ends of the longitudinal roller 13 are respectively connected to the two support plates 122, and the locking bolts are locked on the bottom plate 121. When the large gear 17 and the small gear 15 are set, the large gear 17 and the small gear 15 are arranged on the front side of the front support plate 122, and the protective cover 18 is fixed on the front support plate 122. Such a positioning seat 12 is very simple and reliable, which is not only convenient for manufacturing, but also can provide a very stable and reliable support for the longitudinal roller 13.

[0047] like Fig. 9 and Fig.12 As shown, when the large gear 17 and the small gear 15 are not provided on the positioning seat 12, the two ends of the longitudinal roller 13 are embedded with positioning shafts 131 that can rotate relatively, the outer ends of the two positioning shafts 131 are non-circular shafts, and a clamping notch 1221 matching the outer ends of the positioning shaft 131 is opened on the middle of the upper ends of the two support plates 122, and the outer ends of the two positioning shafts 131 are respectively embedded in the clamping notches 1221 on the two support plates 122. This can greatly improve the stability and reliability of the installation and positioning of the longitudinal roller 13, and it can also facilitate the disassembly and maintenance of the longitudinal roller 13.

[0050] like Fig. 9 As shown, the identification part 113 is a number, and these numbers can identify the diameter size of the cylindrical component that can be supported by the supporting gap 30, so that the adjustment operation can be conveniently performed.
