阅读说明：本技术 皮带硫化接头及其拼接方法 (Belt vulcanization joint and splicing method thereof ) 是由 髙廷虎 何初德 焦杨春 于 2020-04-08 设计创作，主要内容包括：本发明公开了一种皮带硫化接头及其拼接方法,将其中一条皮带接头两侧分别向内去掉48-52mm,形成第一基体,将另一条皮带接头两侧分别保留48-52mm的原边,形成第二基体；在所述第一基体和所述第二基体上分别加工出包括至少三层台阶的第一阶梯部和第二阶梯部,形成第一皮带接头和第二皮带接头；将所述第一阶梯部倒置于所述第二阶梯部上,压紧并用加热以至于使得所述第一皮带接头与所述第二皮带接头紧密粘合。相比于现有厚度减半的拼接方式,本申请第一皮带接头和第二皮带接头处两侧是皮带的原有厚度,一方面提高皮带的边缘抗剪切强度,另一方面能大大增强其抗拉强度和抗扭强度。因而采用该方案拼接方法制成的硫化皮带接头的使用寿命大大延长。(The invention discloses a belt vulcanization joint and a splicing method thereof, wherein two sides of one belt joint are respectively removed inwards by 48-52mm to form a first matrix, and two sides of the other belt joint are respectively reserved with primary sides of 48-52mm to form a second matrix; respectively processing a first step part and a second step part which comprise at least three steps on the first base body and the second base body to form a first belt joint and a second belt joint; inverting the first step portion over the second step portion, compressing and applying heat so as to cause the first belt tab to adhere tightly to the second belt tab. Compare in the concatenation mode that current thickness halved, first belt joint of this application and second belt joint department both sides are the original thickness of belt, improve the marginal shear strength of belt on the one hand, and on the other hand can strengthen its tensile strength and torsional strength greatly. Therefore, the service life of the vulcanized belt joint manufactured by the splicing method is greatly prolonged.)

1. A belt vulcanization joint is characterized by comprising a first belt joint and a second belt joint, wherein the first belt joint comprises a first step part, the second belt joint comprises a second step part, two sides of the first step part respectively retract inwards by 48-52mm in the width direction relative to two sides of a belt, and two sides of the second step part are provided with primary sides of 48-52 mm; the size and shape of the first step part are matched with that of the second step part, and the first step part and the second step part respectively comprise at least three layers of steps.

2. The belt vulcanization joint of claim 1, wherein the first step portion has sides that are recessed by 50mm inward in the width direction from opposite sides of the belt, and the second step portion has sides that have a primary side of 50 mm.

3. The belt vulcanization joint of claim 1, wherein said at least three steps include four steps, each having a thickness of 1/3-1/5 of the belt thickness.

4. The belt vulcanization joint of claim 3, wherein the thickness of each step is 1/4 times the thickness of the belt.

5. The belt vulcanising joint of claim 1 wherein the end surface of each step is a beveled surface.

6. A belt vulcanization joint splicing method is characterized by comprising the following steps:

respectively removing 48-52mm from two sides of one belt joint inwards to form a first base body, and respectively reserving 48-52mm of primary sides on two sides of the other belt joint to form a second base body;

respectively processing a first step part and a second step part which comprise at least three steps on the first base body and the second base body to form a first belt joint and a second belt joint;

inverting the first step portion over the second step portion, compressing and applying heat so as to cause the first belt tab to adhere tightly to the second belt tab.

7. The method of splicing a belt vulcanization joint as claimed in, wherein said first and second substrates are each formed with first and second stepped portions comprising at least three steps, and wherein the step of forming first and second belt joints comprises:

processing four layers of steps on the first base body and the second base body;

processing an end surface of each step of the first step portion and the second step portion into an inclined surface;

and all contact surfaces of the first step part and the second step part are polished to be rough.

8. The belt vulcanization joint of claim 6, wherein the step of each layer has a thickness of 1/3-1/5 of the belt thickness.

9. The belt vulcanization joint of claim 8, wherein each of said steps has a thickness of 1/4 a of the belt thickness.

10. The belt vulcanization joint splicing method of claim 6, wherein when a first step portion and a second step portion including at least three steps are respectively formed on the first base body and the second base body, 2% to 3% of cutting margin is reserved for each of the first step portion and the second step portion.
