Punching die of belt connector

Abstract

The utility model discloses a punching die of a belt connector. The punching die comprises a lengthened punching needle, an inner female die and an outer female die. The inner female die is placed in the belt connector, and a first punching groove is formed in the inner female die in a penetrating mode so that the lengthened punching needle can penetrate through the first punching groove. The outer female die is located below the belt connector, and a second punching groove is formed in the outer female die in a penetrating mode. The first punching groove and the second punching groove are distributed along the same central axis, and the lengthened punching needle sequentially penetrates through the first punching groove and the second punching groove to punch inner holes in the upper face and the lower face of the belt connector at a time. According to the punching die of the belt connector, the length of the punching needle is increased, and the outer female die is additionally arranged, so that on the premise that the product requirement is met, inner holes in the two faces of the belt connector can be punched at the same time as long as a punching machine operates once, and the machining efficiency is greatly improved.

Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a punching die for a belt connector. Background Art

[0002] At present, the belt connectors used in the elevator have been produced and processed by profiles in order to improve production efficiency. The "punching" process generally uses a punch press to punch round holes on both sides.

[0003] like Figure 1 As shown, the specific processing steps include four steps: first, put the belt connector 10 into the inner concave mold 2 of the mold; then run the punching machine to start punching; then take out the punched belt connector 10 on the first side, remove the waste, turn it over and put it into the inner concave mold 2 of the mold; then run the punching machine to punch again; finally, take out the belt connector with holes on both sides, remove the waste, and this process is completed. Each belt connector has holes on both sides, and the original conventional punching mold requires two sides to be punched separately, so the production efficiency is low. Utility Model Content

[0004] The utility model aims to provide a punching die for a belt connector, which lengthens the punch needle and adds an outer concave die. In this way, under the premise of meeting product requirements, the inner holes on two sides of the belt connector can be punched out simultaneously as long as the punch press runs once, which greatly improves the processing efficiency.

[0005] In order to solve the above technical problems, the utility model provides a punching die for a belt connector, comprising an extended punch needle, an inner concave die and an outer concave die; the inner concave die is placed inside the belt connector, and a first punching groove is formed in the inner concave die to allow the extended punch needle to pass through;

[0006] The outer concave mold is located below the belt connector, and a second punching groove is formed through the outer concave mold;

[0007] The first punching groove and the second punching groove are arranged along the same central axis, and the extended punching needle passes through the first punching groove and the second punching groove in sequence to punch out inner holes on the upper and lower surfaces of the belt connector at one time.

[0008] Preferably, the extended punch needle is connected to the punch press through an upper pressing plate, and under the action of the punch press, the extended punch needle is driven to punch and cut the belt connector.

[0009] Preferably, the outer concave mold is embedded in the base.

[0010] Preferably, the outer concave die is open at the bottom, and the waste materials punched out from the upper and lower surfaces of the belt connector are pushed out along the second punch groove under the action of the extended punch needle.

[0011] Preferably, a positioning step is processed on the top of the outer concave mold, and the belt connector is positioned and placed on the outer concave mold.

[0012] Preferably, at least one guide column is provided on the edge of the base to guide the upper pressing plate to move linearly.

[0013] Preferably, a guide sleeve is embedded in the upper pressing plate, and the guide sleeve corresponds to the guide column one by one, so that the upper pressing plate and the base can move up and down in a straight line under the action of the guide column and the guide sleeve.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The punching die of the belt connector lengthens the length of the punch needle and adds an outer concave die. In this way, under the premise of meeting product requirements, the inner holes on both sides of the belt connector can be punched out at the same time as long as the punch press runs once, which greatly improves the processing efficiency.
