Description

Technical Field

[0001] The utility model relates to the field of die repair auxiliary equipment, in particular to a die repair bench vise. Background Art

[0002] At present, when a cylindrical aluminum extrusion die is repaired, it is often supported by a die repair vise that can roll and support the aluminum extrusion die. At present, the rolling support structure on this type of die repair vise is mostly composed of a positioning seat and two longitudinal rollers (for example: the roller bracket disclosed in the patent document of China's authorization announcement number CN220534167U), and the two longitudinal rollers are cylindrical shafts with constant diameters, and the two longitudinal rollers are arranged side by side on the positioning seat. Although such a rolling support structure can play a good supporting role for the cylindrical aluminum extrusion die with a constant outer diameter, with the update and upgrade of the aluminum extrusion die structure, a step-shaft-shaped aluminum extrusion die has appeared (hereinafter referred to as a step-shaft-shaped aluminum extrusion die). When this type of die-repairing vise is used to support the step mold, the two longitudinal rollers on the die-repairing vise can only contact the maximum outer diameter of the step mold, and cannot support other parts of the step mold. In this way, the step mold is prone to unstable center of gravity, which can easily cause large shaking or tipping during the die-repairing process, which can easily affect the efficiency, quality and safety of the die-repairing. Therefore, it is very necessary to redesign the structure of the die-repairing vise. Utility Model Content

[0024] like Figure 1 and Figure 2 As shown, the utility model describes a mold repair vise that can stably support a step mold, comprising a main rolling support mechanism 1 and at least one auxiliary rolling support mechanism 2, wherein the auxiliary rolling support mechanism 2 is arranged above the rolling support surface of the main rolling support mechanism 1, and the rolling center line of the auxiliary rolling support mechanism 2 is parallel to the rolling center line of the main rolling support mechanism 1, and the rolling support surface of the auxiliary rolling support mechanism 2 and the rolling support surface of the main rolling support mechanism 1 together form a step-type rolling support portion 10.

[0025] The mold repair bench vise adopts a main rolling support mechanism 1 and at least one auxiliary rolling support mechanism 2, and the auxiliary rolling support mechanism 2 is arranged above the rolling support surface of the main rolling support mechanism 1, and the rolling center line of the auxiliary rolling support mechanism 2 is parallel to the rolling center line of the main rolling support mechanism 1, and the rolling support surface of the auxiliary rolling support mechanism 2 and the rolling support surface of the main rolling support mechanism 1 form a step-type rolling support part 10. The step-type rolling support part 10 can play a rolling support role on the maximum outer diameter and the step of the step mold, which can stably support the step mold and avoid the unstable center of gravity of the step mold, thereby greatly reducing the large shaking and tipping during the mold repair process, and thus can help improve the efficiency, quality and safety of the mold repair. In addition, the mold repair bench vise can also meet the needs of rolling support for the step mold, which can not only meet the needs of rolling adjustment of the step mold, but also ensure that the rolling adjustment is very stable and smooth, so that it can be convenient and safe to carry out comprehensive mold repair on the step mold.

[0026] like Figure 3 As shown, the auxiliary rolling support mechanism 2 includes a positioning frame 21, two lifting and locking components 22, and two supporting rollers 23. The two lifting and locking components 22 are arranged on the positioning frame 21, and the two supporting rollers 23 are respectively arranged on the two lifting and locking components 22, and the rolling center lines of the two supporting rollers 23 are arranged horizontally and parallelly, and an auxiliary supporting gap 20 is formed between the two supporting rollers 23. Such an auxiliary rolling support mechanism 2 can meet the purpose of adjusting the height of the rolling support surface, so that it can be beneficial to play the role of rolling support for steps of different diameters, and further help to further improve the scope of application of the mold repair vise.

[0027] like Figure 3As shown, both lifting and locking assemblies 22 are oblique lifting and locking assemblies; when the two lifting and locking assemblies 22 are raised, the two lifting and locking assemblies 22 can move away from each other; when the two lifting and locking assemblies 22 are lowered, the two lifting and locking assemblies 22 can move closer to each other. Such arrangement of the lifting and locking assemblies 22 can achieve the purpose of adjusting the width between the two supporting rollers 23, so as to effectively support steps of different diameters, thereby helping to further improve the reliability and applicability of the die repair vise.

[0028] like Figure 3 and Figure 4 As shown, the lifting and locking assembly 22 includes a horizontal shaft 221 and two locking nuts 222. The horizontal shaft 221 can be vertically slidably placed on the positioning frame 21. The two locking nuts 222 are screwed on the horizontal shaft 221, and the two locking nuts 222 can be clamped together on the positioning frame 21. The supporting roller 23 is rollingly sleeved on the end of the horizontal shaft 221. Such a lifting and locking assembly 22 is very simple and reliable, which is not only convenient to manufacture, but also makes the lifting and locking assembly 22 very convenient to operate, and can ensure that the locking is very stable and reliable.

[0029] like Figure 3 As shown, the positioning frame 21 is provided with a horizontally penetrating guide hole 211, the radial cross section of the guide hole 211 is in the shape of an inclined strip, and the horizontal shaft 221 is slidably placed on the guide hole 211. Such a guide hole 211 can play a stable and reliable guiding role for the horizontal shaft 221, thereby helping to improve the accuracy and stability of the lifting and lowering of the horizontal shaft 221.

[0030] like Figure 3 As shown, in order to meet the installation of the two lifting and locking components 22, two horizontally penetrating guide holes 211 are opened on the positioning frame 21, and the length direction of the radial cross section of the two guide holes 211 is arranged in an inverted eight-shaped relationship, so that the two lifting and locking components 22 can be oblique lifting and locking components; and when the two lifting and locking components 22 rise, the two lifting and locking components 22 can accurately move away from each other; when the two lifting and locking components 22 fall, the two lifting and locking components 22 can accurately move closer to each other. Such a limit and guide structure is very simple and reliable, which not only facilitates the manufacture of the auxiliary rolling support mechanism 2, but also makes the auxiliary rolling support mechanism 2 have a very high reliability.

[0031] like Figure 3 As shown, the positioning frame 21 is composed of a vertically arranged positioning plate. Such a positioning frame 21 is extremely simple and reliable, which is not only convenient for manufacturing, but also convenient for the installation and positioning of the lifting and locking assembly 22, and can help ensure that the installation and positioning of the lifting and locking assembly 22 has relatively high stability.

The two horizontal rollers 12 are arranged horizontally side by side on the support frame 11, and the rolling center lines of the two horizontal rollers 12 are parallel to each other. A main support gap 30 is formed between the two horizontal rollers 12; the main support gap 30 and the auxiliary support gap 20 together constitute the step-type rolling support part 10. Such a main rolling support mechanism 1 is very simple and reliable, which is not only convenient for manufacturing, but also conducive to a very stable and reliable support effect on the step mold, thereby helping to further improve the reliability and applicability of the mold repair vise.

[0033] like Figures 5 to 7 As shown, the horizontal roller 12 includes a horizontal roller 121 and two positioning shafts 122. The two ends of the horizontal roller 121 can be rotatably mounted on one end of the two positioning shafts 122, and the other ends of the two positioning shafts 122 are non-circular shafts. The support frame 11 is a horizontally arranged rectangular frame. The top surface of one end of the support frame 11 is provided with at least two longitudinal (longitudinal direction is the front-to-back direction) positioning slots 112 that penetrate the inner cavity 111 of the support frame 11, and each positioning slot 112 is arranged side by side horizontally, and the positioning slot 112 matches the other end of the positioning shaft 122. The horizontal roller 121 is arranged on the inner side of the support frame 11, and the other ends of the two positioning shafts 122 can be detachably embedded in the front and rear ends of the positioning slots 112. In this way, the purpose of transversely adjusting the installation and positioning position of the horizontal roller 12 can be met, thereby meeting the purpose of adjusting the distance between the two horizontal rollers 12, which can change the size of the main support gap 30, and further can be conducive to a better support effect for step molds of more diameters.

In this way, more stable and reliable horizontal rotation can be achieved, thereby helping to further improve the reliability and applicability of the die repair vise.

[0038] like Figure 1 and Figure 2 As shown, the mold repairing vise capable of stably supporting the step mold further comprises a swing positioning bracket 4 and a clamping frame 5. The swing positioning bracket 4 is arranged on or beside the main rolling support mechanism 1, and the clamping frame 5 is arranged on the swing end of the swing positioning bracket 4, and the clamping frame 5 can swing in and out of the top of the step rolling support part 10 under the drive of the swing positioning bracket 4. This can not only enhance the stability and reliability of the installation and positioning of the step mold, but also facilitate the up and down movement of the step mold, thereby better meeting the needs of actual use.

[0039] The swing positioning bracket 4 and the clamping frame 5 together constitute a side fixed mold device, which directly adopts the mold repair vise side fixed mold device designed and patented by the applicant, so as to meet the actual use requirements.

[0040] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, the swing positioning bracket 4 is arranged on the outer wall of the support frame 11, the operating handle 113 is arranged on the outer wall of the support frame 11, the positioning frame 21 is composed of a vertical positioning plate formed by an upward protrusion in the middle part of the rear end of the support frame 11, and two guide holes 211 are longitudinally penetrated through the positioning frame 21, and two locking nuts 222 are respectively clamped on the front and rear surfaces of the positioning frame 21, and the rolling center lines of the horizontal axis 221, the horizontal roller 12 and the supporting roller 23 are longitudinally extended. The two supporting rollers 23 are located in the rear end or the upper rear of the main supporting gap 30. Such a mold repair vise can better meet the needs of actual use.

[0041] like Figure 3 and Figure 4 As shown, the front end of the horizontal shaft 221 is a stepped shaft with a small front and a large rear, and the front end of the horizontal shaft 221 is sleeved with at least one bearing 223, and the supporting roller 23 is sleeved on the bearing 223. A clamping cover 225 is fixed on the front end surface of the horizontal shaft 221 by a screw 224, and the clamping cover 225 and the step at the front end of the horizontal shaft 221 are clamped together to position the bearing 223. A limited stop ring 226 is provided on the horizontal shaft 221 at the rear side of the supporting roller 23, and a limited convex ring 231 is provided on the inner circumferential surface of the rear end of the supporting roller 23, and the limited convex ring 231 is placed between the limited stop ring 226 and the bearing 223; the rear end of the horizontal shaft 221 is a threaded shaft, so that the screw connection requirements of the locking nut 222 can be met. In this way, the supporting roller 23 can be stably limited on the horizontal shaft 221, and the rolling of the supporting roller 23 can be ensured to be very smooth, so as to better meet the requirements of actual use.

[0042] When the step mold has more than two steps, auxiliary rolling support mechanisms 2 equal to the number of steps can be set to support each step respectively, so that a very stable and reliable supporting effect can be achieved for the step mold with multiple steps.
