Description

TECHNICAL FIELD

[0001] The utility model relates to the field of alloy cover, specifically to an alloy cover with a guard plate. BACKGROUND

[0002] The alloy cover is a component made of alloy material, and the existing alloy cover for producing aluminum alloy additive is usually made of 45 carbon steel after quenching and tempering, and the inside is made of hard alloy.

[0003] In the prior art, the upper punch head of the stamping equipment directly contacts the upper part of the alloy cover during the pressing process. Due to the factors such as pressure and speed in the stamping process, it is difficult to achieve absolute uniformity and stability, and in addition, the punch head may have slight defects, thereby causing the alloy cover to be easily damaged. Once damaged, the entire alloy cover will be scrapped, and the price of the alloy cover is relatively high, thereby wasting a lot of financial resources. Therefore, an alloy cover with a guard plate is needed. SUMMARY

[0004] The utility model aims at providing an alloy cover with a guard plate to avoid direct contact between the alloy cover and the punch head of the stamping equipment during the stamping process, avoid damage to the alloy cover, and reduce the waste of financial resources.

[0005] To achieve the above-mentioned purpose, an alloy cover with a guard plate is provided, which comprises an alloy cover and a guard plate. A first butt joint hole is formed in the guard plate, and a screw is threadedly connected to the inner surface of the first butt joint hole. A second butt joint hole is formed in the alloy cover. A plurality of positioning blocks are fixedly connected to the upper surface of the alloy cover. Two positioning grooves are formed in the guard plate.

[0006] According to the alloy cover with a guard plate, the outer surface of the screw is threadedly connected to the second butt joint hole.

[0007] According to the alloy cover with a guard plate, the first butt joint hole and the second butt joint hole are in communication.

[0008] According to the alloy cover with a guard plate, the thickness of the guard plate is 5 mm.

[0009] According to the alloy cover with a guard plate, the outer surface of the positioning block is movably connected to the positioning groove.

[0010] According to the alloy cover with a guard plate, the lower surface of the guard plate is in contact with the alloy cover.

[0011] According to the alloy cover with a guard plate, the number of guard plates is three and they are arranged in a ring array.

[0012] Compared with the prior art, the alloy sleeve with the guard plate has the beneficial effects that:

[0013] 1. The guard plate is arranged to protect the upper part of the alloy sleeve, so that the upper punch of the stamping equipment does not directly contact the upper part of the alloy sleeve, thereby avoiding damage to the alloy sleeve and reducing the waste of financial resources.

[0014] 2. The positioning block and the positioning groove are arranged to provide a positioning structure for the connection between the alloy sleeve and the guard plate. When the alloy sleeve and the guard plate are fixed, the positioning groove is inserted into the positioning block, and the first butt joint hole and the second butt joint hole are aligned, thereby eliminating the need for manual adjustment to align the first butt joint hole and the second butt joint hole, and increasing the convenience of work.

[0015] The additional aspects and advantages of the present application will be partially given in the following description, partially will become obvious from the following description, or will be understood through the practice of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0023] Clearly and completely, the technical solutions in the embodiments of the present application will be described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-5 The present embodiment provides a technical scheme: an alloy sleeve with a guard plate, comprising an alloy sleeve 1 and a guard plate 2, a first butt joint hole 4 is formed on the guard plate 2, the inner surface of the first butt joint hole 4 is threadedly connected with a screw 3, a second butt joint hole 5 is formed on the alloy sleeve 1, the outer surface of the screw 3 is threadedly connected with the second butt joint hole 5, the first butt joint hole 4 and the second butt joint hole 5 are in communication, a plurality of positioning blocks 6 are fixedly connected to the upper surface of the alloy sleeve 1, two positioning grooves 7 are formed on the guard plate 2, the outer surface of the positioning block 6 is movably connected with the positioning groove 7, the lower surface of the guard plate 2 is in contact with the alloy sleeve 1, the thickness of the guard plate 2 is 5mm, the number of the guard plate 2 is three and the guard plate 2 is arranged in a ring array, the guard plate 2 is three separate parts, when one of the guard plates 2 is damaged, only the damaged part of the guard plate 2 needs to be replaced, thereby reducing the waste of resources.

[0025] Working principle: under the action of the guard plate 2, the upper part of the alloy sleeve 1 can be protected, so that in the process of pressing, the upper punch of the stamping equipment is prevented from directly contacting the alloy sleeve 1, thereby protecting the alloy sleeve 1 from being damaged, and if the guard plate 2 is damaged, the screw 3 can be taken out from the first butt joint hole 4 and the second butt joint hole 5 by using a screwdriver or the like, so as to release the connection between the alloy sleeve 1 and the guard plate 2, thereby the damaged guard plate 2 can be taken off from the alloy sleeve 1, then the positioning groove 7 on the new same type of guard plate 2 is inserted on the positioning block 6, so that the first butt joint hole 4 and the second butt joint hole 5 on the guard plate 2 are corresponded together, then the screw 3 is screwed into the first butt joint hole 4 and the second butt joint hole 5 by using a screwdriver or the like, so as to realize the connection and fixation between the alloy sleeve 1 and the guard plate 2.

[0026] The embodiments of the present application have been described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge range of those skilled in the art without departing from the purpose of the present application.
